- absorbent article refers to a device that absorbs and contains liquid, and more specifically, refers to a device that is placed against or in proximity to the body of the wearer to absorb and contain the various exudates discharged from the body.
- doctor refers to an absorbent article that is generally worn by infants and incontinent persons about the lower torso so as to encircle the waist and the legs of the wearer and that is specifically adapted to receive and contain urinary and fecal waste.
- absorbent articles that generally are not intended to be laundered or otherwise restored or reused as an absorbent article, i.e., they are intended to be discarded after a single use and, preferably, to be recycled, composted or otherwise disposed of in an environmentally compatible manner.
- longitudinal refers to a direction running from a waist edge to an opposing waist edge of the article and generally parallel to the maximum linear dimension of the article. Directions within ⁇ 45° of the longitudinal direction are considered to be “longitudinal”.
- lateral refers to a direction running from a side edge to an opposing side edge of the article and generally at a right angle to the longitudinal direction. Directions within ⁇ 45° of the lateral direction are considered to be “lateral”.
- disposed refers to an element being attached and positioned in a particular place or position in a unitary structure with other elements.
- attached refers to elements being connected or united by fastening, adhering, bonding, etc. by any method suitable for the elements being attached together and their constituent materials. Many suitable methods for attaching elements together are well-known, including adhesive bonding, pressure bonding, thermal bonding, mechanical fastening, etc. Such attachment methods may be used to attach elements together over a particular area either continuously or intermittently.
- cohesive refers to the property of a material that sticks to itself but does not to any significant degree stick to other materials.
- water-permeable and water-impermeable refer to the penetrability of materials in the context of the intended usage of disposable absorbent articles. Specifically, the term “water-permeable” refers to a layer or a layered structure having pores, openings, and/or interconnected void spaces that permit liquid water to pass through its thickness in the absence of a forcing pressure. Conversely, the term “water-impermeable” refers to a layer or a layered structure through the thickness of which liquid water cannot pass in the absence of a forcing pressure. A layer or a layered structure that is water-impermeable according to this definition may be permeable to water vapor, i.e., may be “vapor-permeable”.
- hydrostatic pressure test also called a hydrostatic head test or simply a “hydrohead” test.
- Suitable well known compendial methods for hydrohead testing are approved by INDA (formerly the International Nonwovens and Disposables Association, now The Association of the Nonwoven Fabrics Industry) and EDANA (European Disposables And Nonwovens Association).
- proximal and distal refer respectively to the location of an element near to or far from the center of a structure, e.g., the proximal edge of a longitudinally extending element is located nearer to the longitudinal axis than the distal edge of the same element is located relative to the same longitudinal axis.
- one end portion of the exemplary diaper 20 is configured as a front waist region 36 .
- the longitudinally opposing end portion of the diaper 20 is configured as a back waist region 38 .
- An intermediate portion of the diaper 20 extending longitudinally between the front waist region 36 and the back waist region 38 is configured as a crotch region 37 .
- the basic structure of the diaper 20 includes a chassis 100 .
- the chassis 100 has a laterally extending front waist edge 136 in the front waist region 36 and a longitudinally opposing and laterally extending back waist edge 138 in the back waist region 38 .
- the chassis 100 has a longitudinally extending left side edge 137 a and a laterally opposing and longitudinally extending right side edge 137 b , both chassis side edges extending longitudinally between the front waist edge 136 and the back waist edge 138 .
- the chassis 100 has an interior surface 102 and an exterior surface 104 .
- the chassis 100 also has a longitudinal axis 42 and a lateral axis 44 .
- the longitudinal axis 42 extends through the midpoint of the front waist edge 136 and through the midpoint of the back waist edge 138 of the chassis 100 .
- the lateral axis 44 extends through the midpoint of the left side edge 137 a and through the midpoint of the right side edge 137 b of the chassis 100 .
- the exemplary chassis 100 shown in FIG. 1 additionally has longitudinally extending and laterally opposing side flaps 147 a and 147 b that are described in more detail below.
- the basic structure of the diaper 20 also includes an absorbent assembly 200 that is attached to the chassis 100 .
- the absorbent assembly 200 has a laterally extending front edge 236 in the front waist region 36 and a longitudinally opposing and laterally extending back edge 238 in the back waist region 38 .
- the absorbent assembly 200 has a longitudinally extending left side edge 237 a and a laterally opposing and longitudinally extending right side edge 237 b , both absorbent assembly side edges extending longitudinally between the front edge 236 and the back edge 238 .
- the absorbent assembly 200 has an interior surface 202 and an exterior surface 204 .
- the absorbent assembly 200 may be disposed symmetrically with respect to either or both of the longitudinal axis 42 and the lateral axis 44 .
- the absorbent assembly 200 may be disposed asymmetrically with respect to either or both of the longitudinal axis 42 and the lateral axis 44 .
- the absorbent assembly 200 shown in FIG. 1 is disposed symmetrically with respect to the longitudinal axis 42 and asymmetrically with respect to the lateral axis 44 .
- the absorbent assembly 200 shown in FIG. 1 is disposed asymmetrically toward the front waist region 36 .
- the respective front edge 236 , back edge 238 , left side edge 237 a , and right side edge 237 b of the absorbent assembly 200 may lie inward of the respective front waist edge 136 , back waist edge 138 , left side edge 137 a , and right side edge 137 b of the chassis 100 , as in the exemplary diaper 20 shown in FIG. 1 .
- Such a configuration in which one or more of the edges of the absorbent assembly 200 lies inward of the corresponding edges of the chassis 100 may be desirable, for example, in order to allow the relatively more flexible layer or layers adjacent to the edges of the chassis to conform to the body of the wearer and thereby form effective gasket-like seals against the skin of the wearer without being constrained by a relatively thicker and relatively less flexible absorbent assembly.
- one or more of the edges of the absorbent assembly 200 may coincide with the corresponding edge or edges of the chassis 100 .
- the front waist edge 136 and the back waist edge 138 encircle the waist of the wearer, while at the same time the chassis side edges 137 a and 137 b encircle the legs of the wearer.
- the crotch region 37 is generally positioned between the legs of the wearer and the absorbent assembly 200 extends from the front waist region 36 through the crotch region 37 to the back waist region 38 .
- the exemplary chassis 100 is shown laid out flat before the side flaps 147 a and 147 b are formed by folding portions of the chassis 100 laterally inward, i.e., toward the longitudinal axis 42 , to form both the respective side flaps 147 a and 147 b and the side edges 137 a and 137 b of the chassis 100 as shown in FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4 , FIG. 5 , and FIG. 6 .
- the chassis 100 has a longitudinally extending left outer side edge 155 a and a laterally opposing and longitudinally extending right outer side edge 155 b . Both of these chassis outer side edges extend longitudinally between the front waist edge 136 and the back waist edge 138 . As is described in more detail below, when the side flaps 147 a and 147 b are formed by folding portions of the chassis 100 laterally inward, the outer side edges 155 a and 155 b of the chassis form the respective proximal edges 157 a and 157 b of the side flaps.
- the chassis 100 includes a water-impermeable backsheet 26 .
- the backsheet 26 forms an exterior surface that is intended to be placed toward any clothing that is worn over the diaper 20 .
- Many suitable materials for use as the backsheet 26 are well-known, including films of polyethylene and other polyolefins.
- Multi-layer backsheets such as laminates of a film and a nonwoven, are also well-known and may be suitable for use as the backsheet 26 .
- Such a laminate backsheet may be oriented with the nonwoven disposed exteriorly to provide the feel and appearance of a more cloth-like outermost layer than would be provided by using the film as the outermost layer.
- the chassis 100 may, but need not, additionally include an inner liner 22 attached to the backsheet 26 .
- the inner liner 22 may form a portion of the interior surface 102 of the chassis 100 that is intended to be placed against the body of the wearer.
- the inner liner 22 preferably is formed of a soft material that will not irritate the skin of the wearer.
- Such an inner liner 22 may serve to isolate the skin of the wearer from a portion of the backsheet 26 as may be desirable, for example, when the diaper 20 is worn under conditions in which contact between the skin and a backsheet film could be uncomfortable.
- Many suitable materials for the inner liner 22 are well-known in the art, including rayon and synthetic nonwovens such as spunbonded or carded polypropylene or polyester.
- the inner liner 22 may extend to the same width and the same length as the backsheet 26 .
- the edges of the inner liner 22 are not separately identified because the inner liner 22 has the same extent as the backsheet 26 .
- one or more of the edges of the inner liner 22 may lie inward of the edges of the backsheet 26 .
- the edges of the inner liner 22 may lie inward of the edges of the backsheet 26 .
- the portions of the inner liner 22 lying in the gaps between the front edge 236 of the absorbent assembly 200 and the front waist edge 136 of the chassis 100 and between the back edge 238 of the absorbent assembly 200 and the back waist edge 138 of the chassis 100 are exposed, while the remainder of the inner liner 22 is covered by the absorbent assembly 200 and the side flaps 147 a and 147 b .
- a laterally extending strip of the inner liner 22 disposed in the gap in the front waist region 36 and a similar laterally extending strip of the inner liner 22 disposed in the gap in the back waist region 38 may suffice to isolate the skin of the wearer from the backsheet 26 in these two gaps.
- the exemplary chassis 100 has longitudinally extending and laterally opposing side flaps 147 a and 147 b that are disposed on the interior portion of the diaper 20 that faces inwardly toward the wearer and contacts the wearer.
- the side flaps 147 a and 147 b may be formed by folding portions of the chassis 100 laterally inward, i.e., toward the longitudinal axis 42 , to form both the respective side flaps 147 a and 147 b and the side edges 137 a and 137 b of the chassis 100 .
- the side flaps 147 a and 147 b may be formed by attaching an additional layer or layers to the chassis 100 at or adjacent to each of the respective side edges 137 a and 137 b of the chassis 100 .
- each of the additional layer or layers may be attached at or adjacent to its laterally distal edge.
- Portions of a film backsheet 26 that are folded laterally inward to form the side flaps may contact the skin of a wearer during the use of the diaper 20 .
- the alternating ridges and valleys in such a film backsheet that has been deformed in order to make it extensible may provide channels through which air can pass to alleviate any concern regarding such contact of the film backsheet with the skin.
- the chassis 100 may simply be folded loosely or may be creased along a portion of each of its side edges 137 a and 137 b .
- a portion of each of the folded side flaps 147 a and 147 b adjacent to the side edges 137 a and 137 b may be attached to the interior surface 102 of the chassis 100 to achieve a similar result.
- the left side flap 147 a has a proximal edge 157 a and the right side flap 147 b has a proximal edge 157 b .
- the left side flap 147 a and the right side flap 147 b overlap the absorbent assembly 200 , i.e., the proximal edge 157 a and the proximal edge 157 b lie laterally inward of the respective left side edge 237 a and right side edge 237 b of the absorbent assembly 200 .
- Such an overlapped configuration may be desirable in order to impart a more finished appearance to the diaper 20 than that imparted by a non-overlapped configuration.
- the left side flap 147 a and the right side flap 147 b may not overlap the absorbent assembly 200 , i.e., the proximal edge 157 a and the proximal edge 157 b may lie laterally outward of the respective left side edge 237 a and right side edge 237 b of the absorbent assembly 200 .
- the left side flap 147 a and the right side flap 147 b extend the full length of the chassis 100 between the front waist edge 136 and the back waist edge 138 .
- Such a full length configuration may be desirable in order to minimize the amount of waste material and the difficulty associated with the manufacture of the diaper 20 , especially when the method used to manufacture the diaper 20 requires the introduction of the material or materials for the chassis 100 in the form of a continuous web or multiple continuous webs.
- the side flaps may be shorter and extend less than the full distance between the front waist edge 136 and the back waist edge 138 . Such a shorter configuration may be desirable in order to minimize the total amount of material used in the manufacture of the diaper 20 .
- Each of the side flaps 147 a and 147 b is attached to the interior surface 102 of the chassis 100 in attachment zones located in the front waist region 36 and in the back waist region 38 .
- the side flaps 147 a and 147 b are attached to the interior surface 102 of the chassis 100 in the adhesive attachment zones that are shown there and that are more clearly visible in FIG. 10 , where the chassis 100 is shown laid out flat before the side flaps 147 a and 147 b are formed.
- the left side flap 147 a is attached to the interior surface 102 of the chassis 100 in a longitudinally oriented adhesive attachment zone 151 a adjacent to its proximal edge 157 a near the front waist edge 136 and in a longitudinally opposing longitudinally oriented adhesive attachment zone 152 a adjacent to its proximal edge 157 a near the back waist edge 138 .
- the right side flap 147 b is attached to the interior surface 102 of the chassis 100 in a longitudinally oriented adhesive attachment zone 151 b adjacent to its proximal edge 157 b near the front waist edge 136 and in a longitudinally opposing longitudinally oriented adhesive attachment zone 152 b adjacent to its proximal edge 157 b near the back waist edge 138 .
- the adhesive attachment zones may have equal areas or may be unequal in area.
- the front longitudinally oriented adhesive attachment zones 151 a and 151 b may be of one size and the back longitudinally oriented adhesive attachment zones 152 a and 152 b may be of another size.
- the left side flap 147 a is also attached to the interior surface 102 of the chassis 100 in a laterally oriented adhesive attachment zone 153 a adjacent to the front waist edge 136 and in a longitudinally opposing laterally oriented adhesive attachment zone 154 a adjacent to the back waist edge 138 .
- the right side flap 147 b is attached to the interior surface 102 of the chassis 100 in a laterally oriented adhesive attachment zone 153 b adjacent to the front waist edge 136 and in a longitudinally opposing laterally oriented adhesive attachment zone 154 b adjacent to the back waist edge 138 .
- the adhesive attachment zones may have equal areas or may be unequal in area.
- the front laterally oriented adhesive attachment zones 153 a and 153 b may be of one size and the back laterally oriented adhesive attachment zones 154 a and 154 b may be of another size.
- each attachment zone may extend laterally across the full width of the respective side flap.
- a laterally oriented adhesive attachment zone may extend laterally from the chassis left side edge 137 a to the left side flap edge 157 a and thereby attach the entire width of the left side flap 147 a adjacent to the front waist edge 136 to the interior surface 102 of the chassis 100 .
- the side flaps 147 a and 147 b may be attached to the absorbent assembly 200 instead of, or in addition to, being attached to the interior surface 102 of the chassis 100 .
- each side flap preferably includes a longitudinally extensible flap elastic member that is attached adjacent to the proximal edge of the side flap by any of many well-known means.
- Each such flap elastic member may be attached over its entire length or over only a portion of its length. For example, such a flap elastic member may be attached only at or near its longitudinally opposing ends and may be unattached at the middle of its length.
- Such a flap elastic member may be disposed in the crotch region 37 and may extend into one or both of the front waist region 36 and the back waist region 38 .
- an elastic strand 167 a is attached adjacent to the proximal edge 157 a of the left side flap 147 a and extends into both the front waist region 36 and the back waist region 38 .
- an elastic strand 167 b is attached adjacent to the proximal edge 157 b of the right side flap 147 b and extends into both the front waist region 36 and the back waist region 38 .
- Each flap elastic member may be enclosed inside a folded hem.
- the elastic strand 167 a is enclosed inside a hem 170 a formed adjacent to the proximal edge 157 a of the left side flap 147 a and the elastic strand 167 b is enclosed inside a hem 170 b formed adjacent to the proximal edge 157 b of the right side flap 147 b .
- the flap elastic member may be sandwiched between two layers of the chassis, e.g., between the layers of a laminate backsheet or between a backsheet and an inner liner.
- the flap elastic member may be attached on a surface of the chassis 100 and remain exposed.
- the flap elastic member adjacent to each side flap edge allows the side flap edge to extend to the flat uncontracted length of the chassis, e.g., the length of the chassis 100 , as shown in FIG. 1 .
- the flap elastic member contracts to gather the portion of the side flap edge along which the flap elastic member is attached and thereby make the relaxed length of the side flap edge less than the flat uncontracted length of the chassis.
- the elastic strand 167 a contracts to gather the proximal edge 157 a of the left side flap 147 a and the elastic strand 167 b contracts to gather the proximal edge 157 b of the right side flap 147 b .
- the contractive forces of the elastic strands 167 a and 167 b are transmitted at the respective front attachment zones 151 a and 151 b to the interior surface 102 of the chassis 100 at the front waist region 36 .
- the contractive forces of the elastic strands 167 a and 167 b are transmitted at the respective back attachment zones 152 a and 152 b to the interior surface 102 of the chassis 100 at the back waist region 38 .
- These contractive forces pull the front waist region 36 and the back waist region 38 toward each other and thereby bend the diaper 20 into a “U” shape in which the interior of the “U” shape is formed by the portions of the diaper 20 that are intended to be placed toward the body of the wearer.
- the contractive force of the elastic strand 167 a lifts the proximal edge 157 a away from the interior surface 102 of the chassis 100 .
- the contractive force of the elastic strand 167 b lifts the proximal edge 157 b away from the interior surface 102 of the chassis 100 . As shown in FIG.
- this lifting of the proximal edges 157 a and 157 b when the diaper 20 is in the relaxed condition lifts the side flaps 147 a and 147 b into position to serve as side barriers adjacent to the side edges 237 a and 237 b of the absorbent assembly 200 .
- the relaxed “U” shape generally conforms to the body of the wearer such that the front waist region 36 and the back waist region 38 can be fastened together to encircle the waist and the legs of the wearer.
- the elastic strands 167 a and 167 b tend to hold the lifted proximal edges 157 a and 157 b of the side flaps 147 a and 147 b in contact with the body of the wearer and thereby form seals to help prevent the leakage of deposited bodily waste out of the diaper 20 .
- the lateral spacing of the lifted proximal edges 157 a and 157 b is selected to allow the deposit of bodily wastes from the lower torso of the wearer into the space between the lifted side flaps 147 a and 147 b and thereby directly onto the absorbent assembly 200 .
- the width of each of the side flaps 147 a and 147 b in effect becomes its height when the free portion of its proximal edge is lifted and the side flap serves as a side barrier to leakage. This height preferably is selected to allow the lifted proximal edges 157 a and 157 b to fit into the leg creases of the body of the wearer at the same time as the absorbent assembly 200 is held in contact with the body.
- the chassis may have a generally rectangular shape, as in the exemplary diaper 20 shown in FIG. 1 and FIG. 2 .
- a generally rectangular configuration may be desirable in order to minimize the amount of waste material and the difficulty associated with the manufacture of the diaper 20 .
- the chassis may have side edges 137 a and 137 b that are not straight, but instead are curved and/or notched, thereby giving an overall shape in plan view of an hourglass or of an “I” to the diaper 20 .
- Such a non-rectangular configuration may be desirable in order to impart a tailored appearance to the diaper 20 when it is worn.
- Such a non-rectangular configuration may also be desirable in order to impart an impression that the diaper 20 will fit comfortably between the legs of a wearer.
- any one of many well-known ways may be used to form a non-rectangular configuration of the chassis.
- laterally distal portions may be removed from the chassis to make its lateral dimension at and adjacent to the lateral axis 44 smaller than its lateral dimension at and adjacent to the front waist edge 136 and smaller than its lateral dimension at and adjacent to the back waist edge 138 , i.e., to make the chassis narrower in the crotch region 37 than at the waist edges 136 and 138 .
- a portion of each of the side edges 137 a and 137 b may be folded laterally inward in order to achieve the same result.
- Such folded portions of the side edges 137 a and 137 b may be creased or attached, or both creased and attached, in order to prevent their unfoldment.
- FIG. 17 An exemplary form of a non-rectangular configuration of the chassis is shown in FIG. 17 .
- portions of the chassis extending laterally between the outer side edges and the respective side edges in one or both of the waist regions may be left laid out flat, i.e., may remain unfolded, when other portions are folded laterally inward to form the side flaps.
- the portions 106 a and 106 b extending longitudinally from the front waist edge 136 toward the lateral axis 44 in the front waist region 36 and extending laterally between each of the outer side edges 155 a and 155 b and the respective side edges 137 a and 137 b may be left laid out flat, i.e., may remain unfolded.
- the portions 108 a and 108 b extending longitudinally from the back waist edge 138 toward the lateral axis 44 in the back waist region 38 and extending laterally between each of the outer side edges 155 a and 155 b and the respective side edges 137 a and 137 b may be left laid out flat, i.e., may remain unfolded.
- Other portions extending longitudinally between the portions that remain unfolded and through the crotch region 37 may be folded laterally inward to form the side flaps 147 a and 147 b .
- the portions 106 a and 106 b and the portions 108 a and 108 b form “ears” that project laterally outward from each of the waist regions of the diaper.
- portions 106 a and 106 b in the front waist region 36 may remain unfolded and only the portions 108 a and 108 b in the back waist region 38 may be folded laterally inward, or vice versa, in some embodiments.
- An alternative way to form an “I”-shaped non-rectangular configuration of the chassis as shown in FIG. 17 is to form the chassis in the “I” shape and attach an additional layer or layers to the interior surface of the “I”-shaped chassis at or adjacent to each of the side edges 137 a and 137 b of the chassis 100 to form the respective side flaps 147 a and 147 b .
- each of the additional layer or layers may be attached at or adjacent to its laterally distal edge.
- FIG. 18 and FIG. 19 Another exemplary way to form a non-rectangular configuration of the chassis is shown in FIG. 18 and FIG. 19 .
- laterally opposing portions 107 a and 107 b of the chassis between each of the side edges 137 a and 137 b and the respective proximal edges 157 a and 157 b of the side flaps 147 a and 147 b may be folded laterally inward in the crotch region 37 along respective diagonal fold lines 105 a , 105 b , 105 c , and 105 d such that each of the folded portions 107 a and 107 b of the chassis overlaps the absorbent assembly 200 in the crotch region 37 .
- each of the folded portions 107 a and 107 b may be attached to the interior surface 202 of the absorbent assembly in the crotch region 37 at attachment zones 109 a and 109 b .
- This folding and attachment forms “W” shaped folds 112 a and 112 b in the chassis in the crotch region 37 as shown in FIG. 19 , while retaining the configuration of the waist regions 36 and 38 as shown in FIG. 3 and FIG. 6 .
- the overall effect on the shape of the chassis is to form an hourglass-shaped configuration as shown in FIG. 18 .
- the attachment zones 109 a and 109 b may be disposed symmetrically with respect to either or both of the longitudinal axis 42 and the lateral axis 44 .
- the attachment zones 109 a and 109 b may be disposed asymmetrically with respect to either or both of the longitudinal axis 42 and the lateral axis 44 .
- the attachment zones 109 a and 109 b shown in FIG. 18 are disposed symmetrically with respect to the longitudinal axis 42 and asymmetrically with respect to the lateral axis 44 .
- the attachment zones 109 a and 109 b shown in FIG. 1 are disposed asymmetrically toward the front waist region 36 .
- the laterally opposing portions 107 a and 107 b of the chassis may be folded laterally inward in one or both of the waist regions in addition to being folded laterally inward in the crotch region.
- the laterally opposing portions 107 a and 107 b of the chassis may be folded laterally inward over their entire longitudinal lengths.
- the interior surface 102 of each of the folded portions 107 a and 107 b may be attached to the interior surface 202 of the absorbent assembly in the crotch region 37 at attachment zones 109 a and 109 b . This folding and attachment forms “W” shaped folds 112 a and 112 b in the chassis as shown in FIG.
- An hourglass shape may subsequently be imparted to the chassis when the laterally opposing portions are laterally extended by unfolding at their longitudinally distal ends to prepare the disposable absorbent article for use in the configuration shown in FIG. 18 .
- a portion or the whole of the chassis 100 may be made extensible to a degree greater than the inherent extensibility of the material or materials from which the chassis is made, e.g, the backsheet 26 , the inner liner 22 , or both.
- the additional extensibility may be desirable in order to allow the chassis 100 to conform to the body of a wearer during movement by the wearer.
- the additional extensibility may also be desirable, for example, in order to allow the user of a diaper 20 including a chassis 100 having a particular size before extension to extend the front waist region 36 , the back waist region 38 , or both waist regions of the chassis 100 to encircle the waist of an individual wearer whose waist circumference falls within a predefined range, i.e., to tailor the diaper to the individual wearer.
- Such extension of the waist region or regions may give the diaper a generally hourglass shape, so long as the crotch region 37 is extended to a relatively lesser degree than the waist region or regions, and may impart a tailored appearance to the diaper 20 when it is worn.
- the additional extensibility may be desirable in order to minimize the cost of the diaper. For example, an amount of material that would otherwise be sufficient only to make a relatively smaller diaper lacking this extensibility can be used to make a diaper capable of being extended to fit a wearer larger than the smaller diaper would fit. In other words, a lesser amount of material is needed in order to make a diaper capable of being properly fit onto a given size of a wearer when the material is made extensible as described.
- Additional extensibility in the chassis 100 in the lateral direction is relatively more useful than additional extensibility in the longitudinal direction.
- the abdomen of the wearer is likely to expand when the wearer changes posture from standing to sitting and the corresponding abdominal expansion increases the circumference that is encircled by the waist edges of the chassis 100 , necessitating the lateral extension of the waist region or regions.
- Additional lateral extensibility in the chassis 100 may be provided in a variety of ways.
- a material or materials from which the chassis 100 is made may be pleated by any of many known methods.
- all or a portion of the chassis may be made of a formed web material or a formed laminate of web materials like those described in U.S. Pat. No. 5,518,801 issued on 21 May 1996 in the name of Chappell et al.
- An exemplary fragment 300 of such a formed web material 305 is shown in FIG. 20 .
- This formed web material 305 includes distinct laterally extending regions 310 in which the original material has been altered by embossing or another method of deformation to create a pattern of generally longitudinally oriented alternating ridges 312 and valleys 314 .
- the formed web material 305 also includes laterally extending unaltered regions 316 located between the laterally extending altered regions 310 .
- Such a formed web material 305 can be laterally extended beyond its original dimension with the application of relatively less force than that required to extend the same material to the same extent when undeformed.
- the effects of an application of opposing divergent forces directed generally perpendicular to the ridges 312 and valleys 314 include an extension of such a formed web material along an axis between the opposing forces and the generation of a resistive contractive force, primarily in the unaltered regions 316 .
- This resistive force is relatively smaller than the resistive force that is generated by the same material in its unaltered form when extended to the same extent, at least up to an extension at which the ridges and valleys in the altered regions flatten and begin to contribute to the resistive force.
- such formed web materials exhibit an extensible behavior resembling that of traditional elastic materials in the range of extensibility that is useful for the type of lateral extension desired for use in absorbent articles.
- such formed web materials may be made of relatively less expensive materials that are not inherently elastic and, thus, their use may provide an advantage in terms of the cost of manufacturing the absorbent articles.
- the range of extensibility of a web material or a laminate that is formed as described in the Chappell et al. '801 patent can be controlled by the degree of deformation of the altered regions and can be varied from near zero to a maximum that is dependent upon the original material.
- the materials used in the chassis 100 of the exemplary diaper 20 may typically be formed to provide any range of extensibility from near zero to a maximum of more than 100 percent of the original dimension.
- a portion of the chassis 100 may have a maximum extensibility of approximately 20 percent of its original dimension.
- any particular value for the maximum extensibility in the range from approximately one percent to approximately 100 percent may be selected to suit a particular choice of the original size of the diaper 20 and the range of sizes of the intended wearers.
- a diaper having a specific unextended waist opening circumference may be suitable for use on wearers having waist circumferences ranging from equal to this unextended waist opening circumference up to the maximum extensibility.
- the front laterally central portion 117 and the back laterally central portion 118 of the chassis 100 between the attachment zones 151 , 152 , 153 , and 154 where the side flaps 147 a and 147 b are attached to the interior surface 102 of the chassis adjacent to the respective waist edges 137 and 138 may have a different range of extensibility from the portions of the chassis in the attachment zones. Additionally or alternatively, the laterally central portions 117 and 118 may be extensible to a greater or lesser degree when subjected to a given level of opposing tensile forces, i.e., may be more easily or less easily extensible, than the portions of the chassis in the attachment zones.
- the double layering in the areas of the attachment zones after the formation of the side flaps may have an effect of decreasing the degree of lateral extensibility of those areas under a given level of opposing tensile forces, such as by the side flaps acting as parallel “springs” that must be extended in order to extend the underlying attached portion of the chassis.
- the altered regions in the laterally central portions of the chassis may be deformed to a greater or a lesser degree than the altered regions in the attachment zones to render the laterally central portions more easily or less easily extensible than the respective portions in the attachment zones.
- Such differential range of extensibility and/or differential relationship of tensile force to extensibility may be desirable.
- each waist region is typically subjected to a generally uniform level of opposing tensile forces across its entire width, so long as the user grasps the diaper at or adjacent to the laterally opposing side edges.
- the laterally central portion of the chassis is less easily extensible than the portions in the attachment zones, the lateral spacing between the proximal edges 157 a and 157 b of the side flaps will increase less under a given level of applied tensile forces than if the laterally central portion were equally easily extensible or more easily extensible than the portions in the attachment zones.
- This effect of minimizing the change in the lateral spacing between the side flaps may help to ensure that the diaper fits as intended on the body of the wearer by, for example, making it more likely that the proximal edges 157 a and 157 b of the side flaps will fit into the leg creases of the body while the diaper is being worn.
- any of a variety of materials may be formed as described in the Chappell et al. '801 patent.
- a film, a nonwoven, or a laminate of either or both of these materials may be formed to provide the desired extensibility. It is also possible to modify such a material in more than one way while forming it to provide extensibility.
- a film that is originally formed to resist the permeation of vapor through its thickness and to contain fine particles of a granular filler material such as calcium carbonate may be treated as described in the Chappell et al. '801 patent to simultaneously provide extensibility and create small holes that allow water vapor to pass through its thickness.
- the film can simultaneously be rendered extensible and breathable.
- the front waist region 36 and the back waist region 38 can be fastened together to encircle the waist and the legs of the wearer in many well-known ways.
- separate fastening devices such as safety pins, separate tapes, a separate tie strap or straps, and/or a separate belt can be used for this purpose.
- fastening elements can be incorporated into the chassis 100 to enable a user to apply the diaper 20 to the body of the wearer without, or in conjunction with, any separate fastening devices.
- Many suitable types of such incorporated fastening elements are well-known, including, for example, tapes, adhesives, adhesive tape tabs, ties, buttons, hooks, loops, snap fasteners, other forms of mechanical fasteners, cohesive patches, etc.
- These incorporated fastening elements may project laterally outward, i.e., away from the longitudinal axis 42 beyond one or both of the side edges 137 a and 137 b and/or may project longitudinally outward, i.e., away from the lateral axis 44 beyond one or both of the waist edges 136 and 138 or they may lie entirely inside the edges of the diaper 20 .
- some forms of mechanical fasteners that typically require specific mating fastener elements, such as hooks that mate with loops, may be configured to engage with the nonwoven and thereby make the inclusion of the specific mating fastener element unnecessary.
- laterally opposing adhesive tape tabs 114 a and 114 b may be attached to the chassis 100 at or adjacent to the side edges 137 a and 137 b of the diaper 20 .
- the adhesive tape tabs 114 a and 114 b shown in FIG. 21 and FIG. 22 project laterally outward from the respective side edges 137 a and 137 b in the back waist region 38 .
- the adhesive tape tabs 114 a and 114 b shown in FIG. 21 and FIG. 22 may be adhered to the exterior surface 104 of the chassis 100 in the front waist region 36 to fasten the back waist region 38 to the front waist region 36 in a back-over-front manner.
- similar adhesive tape tabs may be attached to the chassis 100 in the front waist region 36 and used to fasten the front waist region 36 to the back waist region 38 in a front-over-back manner.
- Suitable adhesive tapes are available from the 3M Corporation of St. Paul, Minn., U.S.A., under the designation of XMF99121.
- Each of the adhesive tape tabs may be formed of two or more layers and different ones of these layers may be attached to different surfaces of the chassis. For example, as shown in FIG. 21 and FIG. 22 , an interior layer 114 c of the left adhesive tape tab 114 a is attached onto the left side flap 147 a , while an exterior layer 114 d of the left adhesive tape tab 114 a is attached onto the exterior surface 104 of the chassis 100 . Similarly, an interior layer 114 e of the right adhesive tape tab 114 b is attached onto the right side flap 147 b , while an exterior layer 114 f of the right adhesive tape tab 114 b is attached onto the exterior surface 104 of the chassis 100 .
- the interior layers may extend farther toward the longitudinal axis than do the interior layers of the adhesive tape tabs.
- the interior layers may extend farther toward the longitudinal axis than the exterior layers, or both layers may extend equally far toward the longitudinal axis. If the materials onto which the layers of the adhesive tape tab differ in tensile strength or if the attachment of the adhesive tape tab is relatively more secure on one of the surfaces, it may be desirable that the layer that is attached to the stronger material or that is more securely attached to the surface extend farther toward the longitudinal axis in order to distribute the force carried by the adhesive tape tab disproportionately onto the stronger material or the more secure attachment.
- a fastening sheet 116 may be attached onto the exterior surface 104 of the chassis 100 in the front waist region 36 as shown in FIG. 21 and FIG. 22 .
- the fastening sheet 116 shown in FIG. 21 and FIG. 22 lies entirely inside the edges of the diaper 20 .
- two or more discrete fastening sheets may be attached onto the exterior surface of the chassis, instead of a single fastening sheet.
- two laterally opposing fastening sheets may be attached in locations approximately corresponding to the left and right portions of the single fastening sheet 116 .
- the adhesive tape tabs may be adhered to the fastening sheet to fasten the back waist region 38 and the front waist region 36 together.
- the fastening sheet may be formed of a material used elsewhere in the diaper, such as a film or a nonwoven.
- any fastening sheet also be extensible such that the fastening sheet will not restrict the extensibility of the portion of the chassis onto which it is attached.
- an extensible nonwoven may be used for the fastening sheet.
- the fastening sheet serves to distribute the tensile force transmitted by each of the adhesive tape tabs over an area of the backsheet 26 that is larger than the adhered area of the adhesive tape tab.
- a single fastening sheet such as fastening sheet 116 in FIG. 21 and FIG.
- the fastening sheet may, itself, bear a portion of the tensile force between the laterally opposing adhesive tape tabs and thereby relieve a portion of the force exerted on the backsheet.
- the incorporation of such a fastening sheet may be desirable, for example, in order to make it possible to use a relatively inexpensive and relatively weak material for the backsheet 26 .
- the fastening sheet may be formed of a material having greater strength than the backsheet. Such a stronger material may be more expensive per unit area than the backsheet, but the fastening sheet may be relatively smaller than the backsheet. Therefore, the total cost of a diaper having a fastening sheet may be less than the total cost of a diaper having a backsheet having sufficient strength for adhesive tape tabs to be adhered directly to the exterior surface of the backsheet.
- fastening elements in the form of cohesive fastening patches are described in this application and the description of their disposition, configuration, and use is intended to apply to any other type of incorporated fastening element insofar as is practical for each such type of fastening element.
- Exemplary fastening elements in the form of cohesive fastening patches may be formed of an inherently crystalline water-based synthetic elastomer to which a tackifying agent has been added to disrupt the polycrystalline structure and thereby render the elastomer cohesive.
- Such synthetic cohesive products are available from Andover Coated Products, Incorporated, of Salisbury, Mass., U.S.A. and are described in U.S. Pat. No. 6,156,424 issued on 5 Dec. 2000 in the name of Taylor.
- a cohesive elastomeric fastening element preferably remains extensible in use.
- such a cohesive elastomeric fastening element may be capable of extending as the extensible chassis extends.
- Cohesive fastening patches may be formed by the application of a cohesive material directly onto the chassis or onto a separate substrate that is in turn attached to the chassis.
- a cohesive material may be applied in its molten state onto a surface and allowed to cool and solidify to form such a patch.
- the cohesive material may be applied in any of a variety of patterns, such as a continuous film, discrete dots, stripes, polygons, etc., and/or spaced and interconnected geometric elements describing a grid.
- Exemplary cohesive fastening patches are shown incorporated into the chassis in FIG. 1 , FIG. 2 , FIG. 3 , FIG. 6 , FIG. 10 , FIG. 11 , FIG. 12 , FIG. 15 , FIG. 23 , and FIG. 24 .
- a cohesive fastening patch 110 a is disposed on the exterior of the chassis 100 in the front waist region 36 adjacent to the left side edge 137 a and a laterally opposing cohesive fastening patch 110 b is disposed on the exterior of the chassis 100 in the front waist region 36 adjacent to the right side edge 137 b .
- a cohesive fastening patch 120 a is disposed on the interior of the chassis 100 in the back waist region 38 adjacent to the left side edge 137 a and a laterally opposing cohesive fastening patch 120 b is disposed on the interior of the chassis 100 in the back waist region 38 adjacent to the right side edge 137 b .
- the back left cohesive fastening patch 120 a overlaps the front left cohesive fastening patch 110 a and the cohesion of these two cohesive fastening patches fastens the front waist region 36 and the back waist region 38 together at the left side of the diaper 20 .
- the back right cohesive fastening patch 120 b overlaps the front right cohesive fastening patch 110 b and the cohesion of these two cohesive fastening patches fastens the front waist region 36 and the back waist region 38 together at the right side of the diaper 20 .
- the configuration of the cohesive fastening patches shown in these figures is adapted for back-over-front fastening.
- the front cohesive fastening patches may be disposed on the interior of the chassis in the front waist region and the back cohesive fastening patches may be disposed on the exterior of the chassis in order to adapt the configuration of the cohesive fastening patches for front-over-back fastening.
- the cohesive fastening patches are shown overlapped but not exactly aligned along any of their respective edges only for clarity of illustration and can actually be aligned as desired, e.g., to maximize their areas of overlap.
- the cohesive fastening patches may be disposed in a reversible configuration that is adapted to provide the user of the diaper 20 with both options for fastening, i.e., either back-over-front or front-over-back, according to personal preference.
- a back cohesive fastening patch may overlap a front cohesive fastening patch or the front cohesive fastening patch may overlap the back cohesive fastening patch and, in either arrangement, the cohesive fastening patches fasten the front waist region 36 and the back waist region 38 together at the side of the diaper 20 .
- the fastening of the diaper 20 at the sides is reversible so that each side can be fastened in a back-over-front manner or, alternatively, in a front-over-back manner.
- FIG. 25 , FIG. 26 , FIG. 27 , and FIG. 28 Two such reversible configurations of cohesive fastening patches are shown in FIG. 25 , FIG. 26 , FIG. 27 , and FIG. 28 .
- a cohesive fastening patch 110 a wraps around the left side edge 137 a and is disposed on both the exterior and the interior of the chassis 100 in the front waist region 36 adjacent to the left side edge 137 a .
- a laterally opposing cohesive fastening patch 110 b wraps around the right side edge 137 b and is disposed on both the exterior and the interior of the chassis 100 in the front waist region 36 adjacent to the right side edge 137 b .
- Such a continuous configuration may be desirable, for example, in order to allow the cohesive polymer for each cohesive fastening patch to be applied in a single area that is then folded over when the corresponding folded side flap is formed in a manufacturing process.
- a pair of back cohesive fastening patches 120 a and 120 b do not extend around the side edges 137 a and 137 b and thus are not continuous from the exterior to the interior of the chassis 100 . Instead, a back left interior cohesive fastening patch 120 a and a back left exterior cohesive fastening patch 120 c are disposed on the respective interior and exterior of the chassis 100 adjacent to the left side edge 137 a in the back waist region 38 . Similarly, a back right interior cohesive fastening patch 120 b and a back right exterior cohesive fastening patch 120 d are disposed on the respective interior and exterior of the chassis 100 adjacent to the right side edge 137 b in the back waist region 38 .
- any or all of the cohesive fastening patches may extend around the side edges 137 a and 137 b or may be discontinuous from the exterior to the interior of the chassis 100 .
- the fastening patches may be disposed on the interior surface of the chassis and may be abutted in a face-to-face arrangement to form a flanged connection in which, for example, a portion of the side edge 137 a in the back waist region and a portion of the same side edge 137 a in the front waist region are superposed, i.e., unlike an overlapped connection, both of the portions of the side edge are exposed in such a flanged connection.
- the exemplary diapers shown in FIG. 1 , FIG. 2 , FIG. 3 , FIG. 6 , FIG. 10 , FIG. 11 , FIG. 12 , FIG. 15 , FIG. 23 , and FIG. 24 include discrete laterally opposing cohesive fastening patches.
- a single laterally extending cohesive fastening patch may be attached at each of the longitudinally opposing waist regions of the diaper.
- each such single cohesive fastening patch may extend laterally to approximately the lateral extent that is defined by the laterally distal edges of the discrete cohesive fastening patches shown in these figures.
- such a single cohesive fastening patch may have approximately the same extent and be located in approximately the same location as the fastening sheet 116 shown in FIG. 21 and FIG. 22 .
- the absorbent assembly 200 includes an absorbent core 250 .
- the absorbent core 250 has a laterally extending front edge 256 in the front waist region 36 and a longitudinally opposing and laterally extending back edge 258 in the back waist region 38 .
- the absorbent core 250 also has a longitudinally extending left side edge 257 a and a laterally opposing and longitudinally extending right side edge 257 b , both absorbent core side edges extending longitudinally between the front edge 256 and the back edge 258 .
- any or all of the respective front edge 256 , back edge 258 , left side edge 257 a , and right side edge 257 b of the absorbent core 250 may lie inward of the respective front edge 236 , back edge 238 , left side edge 237 a , and right side edge 237 b of the absorbent assembly 200 .
- the absorbent core 250 has its left side edge 257 a and right side edge 257 b located laterally inward of, respectively, the left side edge 237 a and right side edge 237 b of the absorbent assembly 200 .
- one or more of the edges of the absorbent core 250 may coincide with the corresponding edge of the absorbent assembly 200 .
- the front edge 256 and back edge 258 of the absorbent core 250 coincide with the respective front edge 236 and back edge 238 of the absorbent assembly 200 .
- the absorbent assembly 200 may be attached to the chassis 100 over any part or the whole of the area of the absorbent assembly 200 .
- the absorbent assembly 200 is attached on its exterior surface 204 to the chassis 100 in a cruciform attachment pattern, i.e., in an attachment pattern that forms or is arranged in a cross or “+” shape.
- the cruciform attachment pattern may be contiguous, i.e., all of its portions may be touching or connected throughout the pattern in an unbroken sequence.
- the cruciform attachment pattern may include detached portions and thereby lack contiguity but still be arranged such that the shape of the overall pattern is a cruciform.
- a discontiguous cruciform attachment pattern may include a longitudinally extending portion disposed along the longitudinal axis and separate left and right laterally distal portions disposed along or adjacent to the lateral axis and thereby form a cruciform as the shape of the overall pattern.
- FIG. 26 An exemplary contiguous cruciform attachment pattern 210 is shown in FIG. 26 , FIG. 29 , FIG. 30 , and FIG. 31 .
- the portions of the chassis 100 that lie outside such a cruciform attachment pattern are not restrained by attachment to the absorbent assembly 200 and therefore remain extensible.
- a relatively narrow longitudinally extending portion 212 of a cruciform attachment pattern 210 like that shown in FIG. 29 and FIG. 31 leaves the majority of the width of the chassis 100 in the front waist region 36 and in the back waist region 38 freely extensible and thereby allows extension of the chassis 100 in the lateral direction in these regions.
- a relatively wide laterally extending portion 214 of a cruciform attachment pattern 210 may also contribute to the effectiveness of the side flaps 147 a and 147 b when the elastic strands 167 a and 167 b lift the proximal edges 157 a and 157 b into contact with the body of the wearer.
- the side flaps 147 a and 147 b might easily distort and fail to maintain contact with the body.

- the cruciform attachment pattern 210 in FIG. 29 , FIG. 30 , and FIG. 31 extends longitudinally from near the front edge 236 to near the back edge 238 of the absorbent assembly 200 at and adjacent to the longitudinal axis 42 , but does not extend longitudinally to this extent over the full width of the absorbent assembly 200 .
- the cruciform attachment pattern 210 may extend to any or all of the side edges 237 a and 237 b and the front edge 236 and the back edge 238 of the absorbent assembly 200 .
- the cruciform attachment pattern 210 may extend laterally from the left side edge 237 a to the right side edge 237 b of the absorbent assembly 200 , but may extend longitudinally only a part of the distance from the front edge 236 to the back edge 238 of the absorbent assembly 200 .
- the absorbent assembly 200 may be attached to the chassis 100 continuously or intermittently. For example, a film of an adhesive may be applied continuously over the entire area of the cruciform attachment pattern and then used to continuously attach the absorbent assembly to the chassis.
- an adhesive may be applied discontinuously at and inside the boundaries of the cruciform attachment pattern, such as in the form of dots, stripes, beads, spirals, etc., and then used to attach the absorbent assembly to the chassis.
- the cruciform attachment pattern 210 may be disposed symmetrically with respect to either or both of the longitudinal axis 42 and the lateral axis 44 of the chassis 100 .
- the cruciform attachment pattern 210 may be disposed asymmetrically with respect to either or both of the longitudinal axis 42 and the lateral axis 44 .

- the cruciform attachment pattern 210 shown in FIG. 29 is disposed asymmetrically toward the front waist region 36 .
- the laterally extending portion 214 of the cruciform attachment pattern 210 may be located distant from the lateral axis 44 and the longitudinally extending portion 212 of the cruciform attachment pattern 210 may similarly be located distant from the longitudinal axis 42 .
- the cruciform attachment pattern 210 may be disposed symmetrically with respect to either or both of the side edges 237 a and 237 b and the front edge 236 and the back edge 238 of the absorbent assembly 200 .
- the cruciform attachment pattern 210 shown in FIG. 29 is centered on the absorbent assembly 200 .
- the cruciform attachment pattern 210 may be disposed asymmetrically with respect to either or both of the side edges 237 a and 237 b and front edge 236 and back edge 238 of the absorbent assembly 200 , i.e., the cruciform attachment pattern 210 may be disposed off-center on the absorbent assembly 200 .
- the absorbent core 250 may be disposed between a lower covering sheet that is disposed on the exterior face of the absorbent core 250 in a face-to-face arrangement with the interior surface 102 of the chassis and an upper covering sheet that is disposed on the interior face of the absorbent core 250 .
- Such an upper covering sheet and lower covering sheet may be attached together to contain the absorbent core 250 between them and thereby form the absorbent assembly 200 .
- an upper covering sheet 24 and a lower covering sheet 25 are attached together at or adjacent to the side edges 237 a and 237 b of the absorbent assembly 200 in longitudinally extending adhesive attachment zones 29 a and 29 b .
- the upper covering sheet 24 and the lower covering sheet 25 may be attached together in places other than the side edges 237 a and 237 b of the absorbent assembly 200 , e.g., at or adjacent to the end edges 236 and 238 of the absorbent assembly 200 , or at or adjacent to both the end edges 236 and 238 and the side edges 237 a and 237 b.
- the upper covering sheet 24 is water-permeable and allows liquid waste to pass through to the absorbent core 250 , where the liquid waste is absorbed.
- the lower covering sheet 25 may be water-impermeable. However, the lower covering sheet 25 preferably is water-permeable. In embodiments in which both the upper covering sheet 24 and the lower covering sheet 25 are water-permeable, any liquid waste that is deposited onto the upper covering sheet 24 but does not pass through the upper covering sheet 24 to the absorbent core 250 can flow around an edge of the absorbent assembly 200 to reach the lower covering sheet 25 and then pass through the lower covering sheet 25 to the absorbent core 250 .
- the upper covering sheet 24 may form the interior surface 202 of the absorbent assembly 200 that is intended to be placed against the body of the wearer.
- the upper covering sheet 24 preferably is formed of a soft material that will not irritate the skin of the wearer.
- Many materials that are suitable for a water-permeable covering sheet are well-known in the art, including synthetic nonwovens such as spunbonded or carded polypropylene, polyester, or rayon.
- many materials that are suitable for a covering sheet that is water-impermeable are well-known in the art, including the materials that are suitable for the backsheet 26 .
- the upper covering sheet 24 and the lower covering sheet 25 may extend to the same width and the same length.
- one or more of the edges of one of the covering sheets may lie distally relative to the respective edge or edges of the other covering sheet.
- the upper covering sheet may extend longitudinally only to an extent sufficient to cover the absorbent core and the lower covering sheet may extend longitudinally beyond the upper covering sheet toward or to the adjacent waist edge.
- Such an extended covering sheet may serve to isolate the skin of the wearer from a portion of the backsheet 26 as may be desirable, for example, when the diaper 20 is worn under conditions in which contact between the skin and a backsheet film could be uncomfortable.
- Suitable absorbent materials for the absorbent core are well-known, including cellulose fibers in the form of comminuted wood pulp, which is commonly known as “airfelt”, layers or sheets of natural or synthetic fibrous material, superabsorbent polymer, etc. These absorbent materials may be used separately or in combination. Many known absorbent materials may be used in a discrete form, i.e., in the form of fibers, granules, particles, and the like. Such a discrete form of an absorbent material may be immobilized by an adhesive that attaches the discrete pieces together to form a coherent layer or that attaches the discrete pieces to a substrate layer, such as a covering sheet, or that attaches the discrete pieces both to each other and to the substrate layer.
- the discrete form of an absorbent material may be immobilized in pockets formed by a layer of a thermoplastic material, such as a hot melt adhesive, that intermittently contacts and adheres to a substrate, such as a covering sheet, while diverging away from the substrate at the pockets.
- a thermoplastic material such as a hot melt adhesive
- Absorbent assemblies having such structures are described in U.S. Patent Application Publications Nos. 2004/0162536 of 19 Aug. 2004 and 2004/0167486 of 26 Aug. 2004.

- the absorbent core 250 includes particles of superabsorbent polymer 270 that are contained inside pockets 280 formed by a layer 275 of a thermoplastic material. This absorbent core 250 contains no cellulose fibers.
- the absorbent core 250 may include both particles of superabsorbent polymer and airfelt and both materials may be contained inside the pockets formed by the layer of the thermoplastic material.
- the layer 275 of the thermoplastic material intermittently contacts and adheres to the lower covering sheet 25 at the areas of attachment 282 . Between the areas of attachment 282 , the layer 275 diverges away from the lower covering sheet 25 to form the pockets 280 .
- the layer 275 may have the form of a sheet of fibers of the thermoplastic material through which the liquid waste may pass to the particles of superabsorbent polymer 270 to be absorbed.
- a separate upper covering sheet 24 is shown overlying the layer 275 of the thermoplastic material.
- the separate upper covering sheet 24 may be omitted and the layer 275 in the form of a fibrous sheet may serve as the upper covering sheet 24 .
- two absorbent assemblies each like that shown in FIG. 32 except for the omission of the upper covering sheet 24 may be superposed with one absorbent assembly inverted such that its pockets nest into the recesses at the areas of attachment 282 of the other absorbent assembly and the respective single covering sheets distally oppose each other.
- the distally opposing single covering sheets may serve respectively as the upper covering sheet 24 and the lower covering sheet 25 .
- the upper covering sheet 24 and the lower covering sheet 25 are of the same size, i.e., both the upper covering sheet 24 and the lower covering sheet 25 extend to the front edge 236 and back edge 238 , as well as to the left side edge 237 a and right side edge 237 b of the absorbent assembly 200 .

- a single covering sheet may be wrapped around the absorbent core 250 and attached to itself to contain the absorbent core 250 .
- Such a single covering sheet forms an upper layer and a lower layer when wrapped around the absorbent core 250 and, in general, the description of the separate upper covering sheet 24 and lower covering sheet 25 are intended to apply to such upper and lower layers of a wrapped single covering sheet.
- the absorbent core 250 is contained laterally by the covering sheet or sheets being wrapped around the absorbent core 250 or attached together at or adjacent to the left side edge 237 a and right side edge 237 b of the absorbent assembly 200 .
- the upper covering sheet 24 and the lower covering sheet 25 are attached together only in left adhesive attachment zone 29 a and right adhesive attachment zone 29 b at or adjacent to the respective left side edge 237 a and right side edge 237 b of the absorbent assembly 200 .
- the upper covering sheet 24 and the lower covering sheet 25 cannot be attached directly together at or adjacent to the front edge 236 and back edge 238 because the absorbent core 250 extends the full length of the absorbent assembly 200 , i.e. the front edge 256 and back edge 258 of the absorbent core 250 coincide with the respective front edge 236 and back edge 238 of the absorbent assembly 200 .
- the upper and lower layers of the covering sheet or sheets may each be attached to the absorbent core 250 at or adjacent to the front edge 256 and back edge 258 of the absorbent core 250 to form a sandwich.

Description
- This application is a continuation of application Ser. No. 10/770,043 filed Feb. 2, 2004, the substance of which is incorporated herein by reference.
- This invention relates to disposable absorbent articles such as disposable absorbent articles and other articles intended for use on incontinent persons.
- Disposable absorbent articles are designed to absorb and contain bodily waste in order to prevent soiling of the body and clothing of the wearer, as well as bedding or other objects with which the wearer comes into contact.
- As the usage of disposable absorbent articles has expanded, their complexity has increased with the incorporation of additional features serving to enhance their performance and appearance. The costs of the materials and the costs of the manufacturing processes have also increased in conjunction with the increase in complexity. As a result, the prices at which these articles are sold have risen to levels that many potential purchasers around the world cannot afford to pay. Thus, a need exists for a simple disposable absorbent article.
- A disposable absorbent article may comprise a front waist region, a back waist region, a crotch region between the waist regions. The article may comprise a front waist edge and a back waist edge. A longitudinal axis may extend from a midpoint of the front waist edge through the crotch region to a midpoint of the longitudinally opposed back waist edge. A web of the article may comprise an interior surface and an exterior surface. An absorbent assembly of the article may comprise an interior surface and an exterior surface. The web may be folded at a first fold line and attached to itself forming a first hem, and the first hem may comprise a first layer and a second layer, and the second layer may be disposed between the first layer and the backsheet.
- The web may be folded at a second fold line and attached to itself forming a second hem, and the second hem may comprises a first layer and a second layer, and the second layer may disposed between the first layer and the backsheet.
- The web may be folded over at a third fold line toward the longitudinal axis and attached to the interior surface of one or both of the web and absorbent assembly in the front and back waist regions forming a first side flap. The third fold line may form a first side edge of the diaper.
- The web may be folded over at a fourth fold line toward the longitudinal axis and attached to the interior surface of one or both of the web and absorbent assembly in the front and back waist regions forming a second side flap. The fourth fold line may form a second side edge of the diaper.
- The first side flap may comprise the first hem and the second side flap may comprise the second hem. Each of the first and second hems may comprise a longitudinally extending gathering member. The proximal edges of the first and second side flaps may be disposed laterally inward of the respective side edges.

FIG. 32 is a section view of an exemplaryabsorbent assembly 200 showing details of an exemplary absorbent core. - In this description, the following terms have the following meanings:
- The term “absorbent article” refers to a device that absorbs and contains liquid, and more specifically, refers to a device that is placed against or in proximity to the body of the wearer to absorb and contain the various exudates discharged from the body.
- The term “diaper” refers to an absorbent article that is generally worn by infants and incontinent persons about the lower torso so as to encircle the waist and the legs of the wearer and that is specifically adapted to receive and contain urinary and fecal waste.
- The term “disposable” refers to the nature of absorbent articles that generally are not intended to be laundered or otherwise restored or reused as an absorbent article, i.e., they are intended to be discarded after a single use and, preferably, to be recycled, composted or otherwise disposed of in an environmentally compatible manner.
- The term “longitudinal” refers to a direction running from a waist edge to an opposing waist edge of the article and generally parallel to the maximum linear dimension of the article. Directions within ±45° of the longitudinal direction are considered to be “longitudinal”.
- The term “lateral” refers to a direction running from a side edge to an opposing side edge of the article and generally at a right angle to the longitudinal direction. Directions within ±45° of the lateral direction are considered to be “lateral”.
- The term “disposed” refers to an element being attached and positioned in a particular place or position in a unitary structure with other elements.
- The term “attached” refers to elements being connected or united by fastening, adhering, bonding, etc. by any method suitable for the elements being attached together and their constituent materials. Many suitable methods for attaching elements together are well-known, including adhesive bonding, pressure bonding, thermal bonding, mechanical fastening, etc. Such attachment methods may be used to attach elements together over a particular area either continuously or intermittently.
- The term “cohesive” refers to the property of a material that sticks to itself but does not to any significant degree stick to other materials.
- The terms “water-permeable” and “water-impermeable” refer to the penetrability of materials in the context of the intended usage of disposable absorbent articles. Specifically, the term “water-permeable” refers to a layer or a layered structure having pores, openings, and/or interconnected void spaces that permit liquid water to pass through its thickness in the absence of a forcing pressure. Conversely, the term “water-impermeable” refers to a layer or a layered structure through the thickness of which liquid water cannot pass in the absence of a forcing pressure. A layer or a layered structure that is water-impermeable according to this definition may be permeable to water vapor, i.e., may be “vapor-permeable”. As is well known in the art, a common method for measuring the permeability to water of the materials typically used in absorbent articles is a hydrostatic pressure test, also called a hydrostatic head test or simply a “hydrohead” test. Suitable well known compendial methods for hydrohead testing are approved by INDA (formerly the International Nonwovens and Disposables Association, now The Association of the Nonwoven Fabrics Industry) and EDANA (European Disposables And Nonwovens Association).
- The terms “proximal” and “distal” refer respectively to the location of an element near to or far from the center of a structure, e.g., the proximal edge of a longitudinally extending element is located nearer to the longitudinal axis than the distal edge of the same element is located relative to the same longitudinal axis.
- As shown in
FIG. 1 ,FIG. 2 ,FIG. 3 ,FIG. 4 ,FIG. 5 , andFIG. 6 , one end portion of theexemplary diaper 20 is configured as afront waist region 36. The longitudinally opposing end portion of thediaper 20 is configured as aback waist region 38. An intermediate portion of thediaper 20 extending longitudinally between thefront waist region 36 and theback waist region 38 is configured as acrotch region 37. - The basic structure of the
diaper 20 includes achassis 100. Thechassis 100 has a laterally extendingfront waist edge 136 in thefront waist region 36 and a longitudinally opposing and laterally extending backwaist edge 138 in theback waist region 38. Thechassis 100 has a longitudinally extendingleft side edge 137 a and a laterally opposing and longitudinally extendingright side edge 137 b, both chassis side edges extending longitudinally between thefront waist edge 136 and theback waist edge 138. Thechassis 100 has aninterior surface 102 and anexterior surface 104. Thechassis 100 also has alongitudinal axis 42 and alateral axis 44. Thelongitudinal axis 42 extends through the midpoint of thefront waist edge 136 and through the midpoint of theback waist edge 138 of thechassis 100. Thelateral axis 44 extends through the midpoint of theleft side edge 137 a and through the midpoint of theright side edge 137 b of thechassis 100. Theexemplary chassis 100 shown inFIG. 1 additionally has longitudinally extending and laterally opposing side flaps 147 a and 147 b that are described in more detail below. - The basic structure of the
diaper 20 also includes anabsorbent assembly 200 that is attached to thechassis 100. Theabsorbent assembly 200 has a laterally extendingfront edge 236 in thefront waist region 36 and a longitudinally opposing and laterally extending backedge 238 in theback waist region 38. Theabsorbent assembly 200 has a longitudinally extendingleft side edge 237 a and a laterally opposing and longitudinally extendingright side edge 237 b, both absorbent assembly side edges extending longitudinally between thefront edge 236 and theback edge 238. Theabsorbent assembly 200 has aninterior surface 202 and anexterior surface 204. Theabsorbent assembly 200 may be disposed symmetrically with respect to either or both of thelongitudinal axis 42 and thelateral axis 44. Alternatively, theabsorbent assembly 200 may be disposed asymmetrically with respect to either or both of thelongitudinal axis 42 and thelateral axis 44. For example, theabsorbent assembly 200 shown inFIG. 1 is disposed symmetrically with respect to thelongitudinal axis 42 and asymmetrically with respect to thelateral axis 44. In particular, theabsorbent assembly 200 shown inFIG. 1 is disposed asymmetrically toward thefront waist region 36. - The respective
front edge 236, backedge 238,left side edge 237 a, andright side edge 237 b of theabsorbent assembly 200 may lie inward of the respectivefront waist edge 136, backwaist edge 138,left side edge 137 a, andright side edge 137 b of thechassis 100, as in theexemplary diaper 20 shown inFIG. 1 . Such a configuration in which one or more of the edges of theabsorbent assembly 200 lies inward of the corresponding edges of thechassis 100 may be desirable, for example, in order to allow the relatively more flexible layer or layers adjacent to the edges of the chassis to conform to the body of the wearer and thereby form effective gasket-like seals against the skin of the wearer without being constrained by a relatively thicker and relatively less flexible absorbent assembly. Alternatively, one or more of the edges of theabsorbent assembly 200 may coincide with the corresponding edge or edges of thechassis 100. - As shown in
FIG. 7 ,FIG. 8 , andFIG. 9 , when thediaper 20 is worn on the lower torso of a wearer, thefront waist edge 136 and theback waist edge 138 encircle the waist of the wearer, while at the same time the chassis side edges 137 a and 137 b encircle the legs of the wearer. At the same time, thecrotch region 37 is generally positioned between the legs of the wearer and theabsorbent assembly 200 extends from thefront waist region 36 through thecrotch region 37 to theback waist region 38. - In
FIG. 10 ,FIG. 11 ,FIG. 12 ,FIG. 13 ,FIG. 14 , andFIG. 15 , theexemplary chassis 100 is shown laid out flat before the side flaps 147 a and 147 b are formed by folding portions of thechassis 100 laterally inward, i.e., toward thelongitudinal axis 42, to form both the respective side flaps 147 a and 147 b and the side edges 137 a and 137 b of thechassis 100 as shown inFIG. 1 ,FIG. 2 ,FIG. 3 ,FIG. 4 ,FIG. 5 , andFIG. 6 . In this condition of being laid out flat, thechassis 100 has a longitudinally extending leftouter side edge 155 a and a laterally opposing and longitudinally extending rightouter side edge 155 b. Both of these chassis outer side edges extend longitudinally between thefront waist edge 136 and theback waist edge 138. As is described in more detail below, when the side flaps 147 a and 147 b are formed by folding portions of thechassis 100 laterally inward, the outer side edges 155 a and 155 b of the chassis form the respectiveproximal edges chassis 100 includes a water-impermeable backsheet 26. Thebacksheet 26 forms an exterior surface that is intended to be placed toward any clothing that is worn over thediaper 20. Many suitable materials for use as thebacksheet 26 are well-known, including films of polyethylene and other polyolefins. Multi-layer backsheets, such as laminates of a film and a nonwoven, are also well-known and may be suitable for use as thebacksheet 26. Such a laminate backsheet may be oriented with the nonwoven disposed exteriorly to provide the feel and appearance of a more cloth-like outermost layer than would be provided by using the film as the outermost layer. - The
chassis 100 may, but need not, additionally include aninner liner 22 attached to thebacksheet 26. Theinner liner 22 may form a portion of theinterior surface 102 of thechassis 100 that is intended to be placed against the body of the wearer. Theinner liner 22 preferably is formed of a soft material that will not irritate the skin of the wearer. Such aninner liner 22 may serve to isolate the skin of the wearer from a portion of thebacksheet 26 as may be desirable, for example, when thediaper 20 is worn under conditions in which contact between the skin and a backsheet film could be uncomfortable. Many suitable materials for theinner liner 22 are well-known in the art, including rayon and synthetic nonwovens such as spunbonded or carded polypropylene or polyester. Theinner liner 22 may extend to the same width and the same length as thebacksheet 26. For example, in theexemplary chassis 100 shown inFIG. 10 andFIG. 11 , the edges of theinner liner 22 are not separately identified because theinner liner 22 has the same extent as thebacksheet 26. - Alternatively, one or more of the edges of the
inner liner 22 may lie inward of the edges of thebacksheet 26. For example, with reference to theexemplary diaper 20 shown inFIG. 1 , only the portions of theinner liner 22 lying in the gaps between thefront edge 236 of theabsorbent assembly 200 and thefront waist edge 136 of thechassis 100 and between theback edge 238 of theabsorbent assembly 200 and theback waist edge 138 of thechassis 100 are exposed, while the remainder of theinner liner 22 is covered by theabsorbent assembly 200 and the side flaps 147 a and 147 b. Therefore, a laterally extending strip of theinner liner 22 disposed in the gap in thefront waist region 36 and a similar laterally extending strip of theinner liner 22 disposed in the gap in theback waist region 38 may suffice to isolate the skin of the wearer from thebacksheet 26 in these two gaps. - As shown in
FIG. 1 ,FIG. 2 ,FIG. 3 ,FIG. 4 ,FIG. 5 , andFIG. 6 , theexemplary chassis 100 has longitudinally extending and laterally opposing side flaps 147 a and 147 b that are disposed on the interior portion of thediaper 20 that faces inwardly toward the wearer and contacts the wearer. The side flaps 147 a and 147 b may be formed by folding portions of thechassis 100 laterally inward, i.e., toward thelongitudinal axis 42, to form both the respective side flaps 147 a and 147 b and the side edges 137 a and 137 b of thechassis 100. Alternatively, the side flaps 147 a and 147 b may be formed by attaching an additional layer or layers to thechassis 100 at or adjacent to each of the respective side edges 137 a and 137 b of thechassis 100. In embodiments in which the side flaps are formed by attaching an additional layer or layers to the chassis, each of the additional layer or layers may be attached at or adjacent to its laterally distal edge. - Portions of a
film backsheet 26 that are folded laterally inward to form the side flaps may contact the skin of a wearer during the use of thediaper 20. However, the alternating ridges and valleys in such a film backsheet that has been deformed in order to make it extensible may provide channels through which air can pass to alleviate any concern regarding such contact of the film backsheet with the skin. - In embodiments in which portions of the
chassis 100 are folded laterally inward to form the side flaps 147 a and 147 b, thechassis 100 may simply be folded loosely or may be creased along a portion of each of its side edges 137 a and 137 b. For example, it may be desirable to form creases along portions of the side edges 137 a and 137 b in thecrotch region 37 in order to impart a more finished appearance to thediaper 20. Alternatively or in addition to creasing, a portion of each of the folded side flaps 147 a and 147 b adjacent to the side edges 137 a and 137 b may be attached to theinterior surface 102 of thechassis 100 to achieve a similar result. - The
left side flap 147 a has aproximal edge 157 a and theright side flap 147 b has aproximal edge 157 b. In theexemplary diaper 20 shown inFIG. 1 , theleft side flap 147 a and theright side flap 147 b overlap theabsorbent assembly 200, i.e., theproximal edge 157 a and theproximal edge 157 b lie laterally inward of the respectiveleft side edge 237 a andright side edge 237 b of theabsorbent assembly 200. Such an overlapped configuration may be desirable in order to impart a more finished appearance to thediaper 20 than that imparted by a non-overlapped configuration. Alternatively, theleft side flap 147 a and theright side flap 147 b may not overlap theabsorbent assembly 200, i.e., theproximal edge 157 a and theproximal edge 157 b may lie laterally outward of the respectiveleft side edge 237 a andright side edge 237 b of theabsorbent assembly 200. - In the
exemplary chassis 100 shown inFIG. 1 , theleft side flap 147 a and theright side flap 147 b extend the full length of thechassis 100 between thefront waist edge 136 and theback waist edge 138. Such a full length configuration may be desirable in order to minimize the amount of waste material and the difficulty associated with the manufacture of thediaper 20, especially when the method used to manufacture thediaper 20 requires the introduction of the material or materials for thechassis 100 in the form of a continuous web or multiple continuous webs. Alternatively, the side flaps may be shorter and extend less than the full distance between thefront waist edge 136 and theback waist edge 138. Such a shorter configuration may be desirable in order to minimize the total amount of material used in the manufacture of thediaper 20. - Each of the side flaps 147 a and 147 b is attached to the
interior surface 102 of thechassis 100 in attachment zones located in thefront waist region 36 and in theback waist region 38. For example, in thechassis 100 shown inFIG. 1 , the side flaps 147 a and 147 b are attached to theinterior surface 102 of thechassis 100 in the adhesive attachment zones that are shown there and that are more clearly visible inFIG. 10 , where thechassis 100 is shown laid out flat before the side flaps 147 a and 147 b are formed. In particular, theleft side flap 147 a is attached to theinterior surface 102 of thechassis 100 in a longitudinally orientedadhesive attachment zone 151 a adjacent to itsproximal edge 157 a near thefront waist edge 136 and in a longitudinally opposing longitudinally orientedadhesive attachment zone 152 a adjacent to itsproximal edge 157 a near theback waist edge 138. Similarly, theright side flap 147 b is attached to theinterior surface 102 of thechassis 100 in a longitudinally orientedadhesive attachment zone 151 b adjacent to itsproximal edge 157 b near thefront waist edge 136 and in a longitudinally opposing longitudinally orientedadhesive attachment zone 152 b adjacent to itsproximal edge 157 b near theback waist edge 138. The adhesive attachment zones may have equal areas or may be unequal in area. For example, the front longitudinally orientedadhesive attachment zones adhesive attachment zones - In the
exemplary chassis 100 shown inFIG. 1 , theleft side flap 147 a is also attached to theinterior surface 102 of thechassis 100 in a laterally orientedadhesive attachment zone 153 a adjacent to thefront waist edge 136 and in a longitudinally opposing laterally orientedadhesive attachment zone 154 a adjacent to theback waist edge 138. Similarly, theright side flap 147 b is attached to theinterior surface 102 of thechassis 100 in a laterally orientedadhesive attachment zone 153 b adjacent to thefront waist edge 136 and in a longitudinally opposing laterally orientedadhesive attachment zone 154 b adjacent to theback waist edge 138. The adhesive attachment zones may have equal areas or may be unequal in area. For example, the front laterally orientedadhesive attachment zones adhesive attachment zones - Alternatively, each attachment zone may extend laterally across the full width of the respective side flap. For example, a laterally oriented adhesive attachment zone may extend laterally from the chassis left
side edge 137 a to the leftside flap edge 157 a and thereby attach the entire width of theleft side flap 147 a adjacent to thefront waist edge 136 to theinterior surface 102 of thechassis 100. In embodiments in which thefront edge 236 or theback edge 238 of theabsorbent assembly 200 coincides with the respectivefront waist edge 136 or backwaist edge 138 of thechassis 100 and the side flaps 147 a and 147 b overlap theabsorbent assembly 200, the side flaps 147 a and 147 b may be attached to theabsorbent assembly 200 instead of, or in addition to, being attached to theinterior surface 102 of thechassis 100. - Between the attachment zones, the
proximal edges interior surface 102 of thechassis 100 or to theabsorbent assembly 200. Also between the attachment zones, each side flap preferably includes a longitudinally extensible flap elastic member that is attached adjacent to the proximal edge of the side flap by any of many well-known means. Each such flap elastic member may be attached over its entire length or over only a portion of its length. For example, such a flap elastic member may be attached only at or near its longitudinally opposing ends and may be unattached at the middle of its length. Such a flap elastic member may be disposed in thecrotch region 37 and may extend into one or both of thefront waist region 36 and theback waist region 38. For example, in theexemplary chassis 100 shown inFIG. 1 , anelastic strand 167 a is attached adjacent to theproximal edge 157 a of theleft side flap 147 a and extends into both thefront waist region 36 and theback waist region 38. Similarly, anelastic strand 167 b is attached adjacent to theproximal edge 157 b of theright side flap 147 b and extends into both thefront waist region 36 and theback waist region 38. - Each flap elastic member may be enclosed inside a folded hem. For example, in the
exemplary chassis 100 shown inFIG. 4 andFIG. 5 , theelastic strand 167 a is enclosed inside ahem 170 a formed adjacent to theproximal edge 157 a of theleft side flap 147 a and theelastic strand 167 b is enclosed inside ahem 170 b formed adjacent to theproximal edge 157 b of theright side flap 147 b. Alternatively, the flap elastic member may be sandwiched between two layers of the chassis, e.g., between the layers of a laminate backsheet or between a backsheet and an inner liner. As another alternative, the flap elastic member may be attached on a surface of thechassis 100 and remain exposed. - When stretched, the flap elastic member adjacent to each side flap edge allows the side flap edge to extend to the flat uncontracted length of the chassis, e.g., the length of the
chassis 100, as shown inFIG. 1 . When allowed to relax, the flap elastic member contracts to gather the portion of the side flap edge along which the flap elastic member is attached and thereby make the relaxed length of the side flap edge less than the flat uncontracted length of the chassis. For example, when theexemplary diaper 20 is in a relaxed condition as shown inFIG. 16 , theelastic strand 167 a contracts to gather theproximal edge 157 a of theleft side flap 147 a and theelastic strand 167 b contracts to gather theproximal edge 157 b of theright side flap 147 b. The contractive forces of theelastic strands front attachment zones interior surface 102 of thechassis 100 at thefront waist region 36. Similarly, the contractive forces of theelastic strands back attachment zones interior surface 102 of thechassis 100 at theback waist region 38. These contractive forces pull thefront waist region 36 and theback waist region 38 toward each other and thereby bend thediaper 20 into a “U” shape in which the interior of the “U” shape is formed by the portions of thediaper 20 that are intended to be placed toward the body of the wearer. Because theproximal edge 157 a remains free between theattachment zones elastic strand 167 a lifts theproximal edge 157 a away from theinterior surface 102 of thechassis 100. Similarly, because theproximal edge 157 b remains free between theattachment zones elastic strand 167 b lifts theproximal edge 157 b away from theinterior surface 102 of thechassis 100. As shown inFIG. 16 , this lifting of theproximal edges diaper 20 is in the relaxed condition lifts the side flaps 147 a and 147 b into position to serve as side barriers adjacent to the side edges 237 a and 237 b of theabsorbent assembly 200. - When the
diaper 20 is worn, the relaxed “U” shape generally conforms to the body of the wearer such that thefront waist region 36 and theback waist region 38 can be fastened together to encircle the waist and the legs of the wearer. When thediaper 20 is worn in this manner, theelastic strands proximal edges diaper 20. The lateral spacing of the liftedproximal edges absorbent assembly 200. The width of each of the side flaps 147 a and 147 b in effect becomes its height when the free portion of its proximal edge is lifted and the side flap serves as a side barrier to leakage. This height preferably is selected to allow the liftedproximal edges absorbent assembly 200 is held in contact with the body. - In the finished diaper, the chassis may have a generally rectangular shape, as in the
exemplary diaper 20 shown inFIG. 1 andFIG. 2 . Such a generally rectangular configuration may be desirable in order to minimize the amount of waste material and the difficulty associated with the manufacture of thediaper 20. Alternatively, the chassis may haveside edges diaper 20. Such a non-rectangular configuration may be desirable in order to impart a tailored appearance to thediaper 20 when it is worn. Such a non-rectangular configuration may also be desirable in order to impart an impression that thediaper 20 will fit comfortably between the legs of a wearer. Any one of many well-known ways may be used to form a non-rectangular configuration of the chassis. For example, laterally distal portions may be removed from the chassis to make its lateral dimension at and adjacent to thelateral axis 44 smaller than its lateral dimension at and adjacent to thefront waist edge 136 and smaller than its lateral dimension at and adjacent to theback waist edge 138, i.e., to make the chassis narrower in thecrotch region 37 than at the waist edges 136 and 138. Alternatively, a portion of each of the side edges 137 a and 137 b may be folded laterally inward in order to achieve the same result. Such folded portions of the side edges 137 a and 137 b may be creased or attached, or both creased and attached, in order to prevent their unfoldment. - An exemplary form of a non-rectangular configuration of the chassis is shown in
FIG. 17 . As shown in this figure, portions of the chassis extending laterally between the outer side edges and the respective side edges in one or both of the waist regions may be left laid out flat, i.e., may remain unfolded, when other portions are folded laterally inward to form the side flaps. For example, as shown inFIG. 17 , theportions front waist edge 136 toward thelateral axis 44 in thefront waist region 36 and extending laterally between each of the outer side edges 155 a and 155 b and the respective side edges 137 a and 137 b may be left laid out flat, i.e., may remain unfolded. Similarly, theportions back waist edge 138 toward thelateral axis 44 in theback waist region 38 and extending laterally between each of the outer side edges 155 a and 155 b and the respective side edges 137 a and 137 b may be left laid out flat, i.e., may remain unfolded. Other portions extending longitudinally between the portions that remain unfolded and through thecrotch region 37 may be folded laterally inward to form the side flaps 147 a and 147 b. Theportions portions FIG. 17 . It is not necessary that portions remain unfolded at both ends as shown inFIG. 17 . For example, theportions front waist region 36 may remain unfolded and only theportions back waist region 38 may be folded laterally inward, or vice versa, in some embodiments. - An alternative way to form an “I”-shaped non-rectangular configuration of the chassis as shown in
FIG. 17 is to form the chassis in the “I” shape and attach an additional layer or layers to the interior surface of the “I”-shaped chassis at or adjacent to each of the side edges 137 a and 137 b of thechassis 100 to form the respective side flaps 147 a and 147 b. In embodiments in which the side flaps are formed by attaching an additional layer or layers to the chassis, each of the additional layer or layers may be attached at or adjacent to its laterally distal edge. - Another exemplary way to form a non-rectangular configuration of the chassis is shown in
FIG. 18 andFIG. 19 . As shown in these figures, laterally opposingportions proximal edges crotch region 37 along respectivediagonal fold lines portions absorbent assembly 200 in thecrotch region 37. Theinterior surface 102 of each of the foldedportions interior surface 202 of the absorbent assembly in thecrotch region 37 atattachment zones crotch region 37 as shown inFIG. 19 , while retaining the configuration of thewaist regions FIG. 3 andFIG. 6 . The overall effect on the shape of the chassis is to form an hourglass-shaped configuration as shown inFIG. 18 . Theattachment zones longitudinal axis 42 and thelateral axis 44. Alternatively, theattachment zones longitudinal axis 42 and thelateral axis 44. For example, theattachment zones FIG. 18 are disposed symmetrically with respect to thelongitudinal axis 42 and asymmetrically with respect to thelateral axis 44. In particular, theattachment zones FIG. 1 are disposed asymmetrically toward thefront waist region 36. - Alternatively, the laterally opposing
portions portions interior surface 102 of each of the foldedportions interior surface 202 of the absorbent assembly in thecrotch region 37 atattachment zones FIG. 19 over the entire longitudinal lengths of the laterally opposingportions FIG. 18 . - A portion or the whole of the
chassis 100 may be made extensible to a degree greater than the inherent extensibility of the material or materials from which the chassis is made, e.g, thebacksheet 26, theinner liner 22, or both. The additional extensibility may be desirable in order to allow thechassis 100 to conform to the body of a wearer during movement by the wearer. The additional extensibility may also be desirable, for example, in order to allow the user of adiaper 20 including achassis 100 having a particular size before extension to extend thefront waist region 36, theback waist region 38, or both waist regions of thechassis 100 to encircle the waist of an individual wearer whose waist circumference falls within a predefined range, i.e., to tailor the diaper to the individual wearer. Such extension of the waist region or regions may give the diaper a generally hourglass shape, so long as thecrotch region 37 is extended to a relatively lesser degree than the waist region or regions, and may impart a tailored appearance to thediaper 20 when it is worn. In addition, the additional extensibility may be desirable in order to minimize the cost of the diaper. For example, an amount of material that would otherwise be sufficient only to make a relatively smaller diaper lacking this extensibility can be used to make a diaper capable of being extended to fit a wearer larger than the smaller diaper would fit. In other words, a lesser amount of material is needed in order to make a diaper capable of being properly fit onto a given size of a wearer when the material is made extensible as described. - Additional extensibility in the
chassis 100 in the lateral direction is relatively more useful than additional extensibility in the longitudinal direction. The abdomen of the wearer is likely to expand when the wearer changes posture from standing to sitting and the corresponding abdominal expansion increases the circumference that is encircled by the waist edges of thechassis 100, necessitating the lateral extension of the waist region or regions. - Additional lateral extensibility in the
chassis 100 may be provided in a variety of ways. For example, a material or materials from which thechassis 100 is made may be pleated by any of many known methods. Alternatively, all or a portion of the chassis may be made of a formed web material or a formed laminate of web materials like those described in U.S. Pat. No. 5,518,801 issued on 21 May 1996 in the name of Chappell et al. Anexemplary fragment 300 of such a formedweb material 305 is shown inFIG. 20 . This formedweb material 305 includes distinct laterally extendingregions 310 in which the original material has been altered by embossing or another method of deformation to create a pattern of generally longitudinally oriented alternatingridges 312 andvalleys 314. The formedweb material 305 also includes laterally extendingunaltered regions 316 located between the laterally extendingaltered regions 310. - Such a formed
web material 305 can be laterally extended beyond its original dimension with the application of relatively less force than that required to extend the same material to the same extent when undeformed. In particular, the effects of an application of opposing divergent forces directed generally perpendicular to theridges 312 andvalleys 314 include an extension of such a formed web material along an axis between the opposing forces and the generation of a resistive contractive force, primarily in theunaltered regions 316. This resistive force is relatively smaller than the resistive force that is generated by the same material in its unaltered form when extended to the same extent, at least up to an extension at which the ridges and valleys in the altered regions flatten and begin to contribute to the resistive force. Thus, such formed web materials exhibit an extensible behavior resembling that of traditional elastic materials in the range of extensibility that is useful for the type of lateral extension desired for use in absorbent articles. However, such formed web materials may be made of relatively less expensive materials that are not inherently elastic and, thus, their use may provide an advantage in terms of the cost of manufacturing the absorbent articles. - The range of extensibility of a web material or a laminate that is formed as described in the Chappell et al. '801 patent can be controlled by the degree of deformation of the altered regions and can be varied from near zero to a maximum that is dependent upon the original material. For example, the materials used in the
chassis 100 of theexemplary diaper 20 may typically be formed to provide any range of extensibility from near zero to a maximum of more than 100 percent of the original dimension. In some embodiments of the present invention, a portion of thechassis 100 may have a maximum extensibility of approximately 20 percent of its original dimension. However, any particular value for the maximum extensibility in the range from approximately one percent to approximately 100 percent may be selected to suit a particular choice of the original size of thediaper 20 and the range of sizes of the intended wearers. In particular, a diaper having a specific unextended waist opening circumference may be suitable for use on wearers having waist circumferences ranging from equal to this unextended waist opening circumference up to the maximum extensibility. - The front laterally
central portion 117 and the back laterallycentral portion 118 of thechassis 100 between the attachment zones 151, 152, 153, and 154 where the side flaps 147 a and 147 b are attached to theinterior surface 102 of the chassis adjacent to the respective waist edges 137 and 138 may have a different range of extensibility from the portions of the chassis in the attachment zones. Additionally or alternatively, the laterallycentral portions - Such differential range of extensibility and/or differential relationship of tensile force to extensibility may be desirable. For example, when the waist regions are laterally extended by a user when applying a diaper to the body of a wearer, each waist region is typically subjected to a generally uniform level of opposing tensile forces across its entire width, so long as the user grasps the diaper at or adjacent to the laterally opposing side edges. If the laterally central portion of the chassis is less easily extensible than the portions in the attachment zones, the lateral spacing between the
proximal edges proximal edges - Any of a variety of materials may be formed as described in the Chappell et al. '801 patent. For example, a film, a nonwoven, or a laminate of either or both of these materials may be formed to provide the desired extensibility. It is also possible to modify such a material in more than one way while forming it to provide extensibility. For example, a film that is originally formed to resist the permeation of vapor through its thickness and to contain fine particles of a granular filler material such as calcium carbonate may be treated as described in the Chappell et al. '801 patent to simultaneously provide extensibility and create small holes that allow water vapor to pass through its thickness. Thus, the film can simultaneously be rendered extensible and breathable.
- The
front waist region 36 and theback waist region 38 can be fastened together to encircle the waist and the legs of the wearer in many well-known ways. For example, separate fastening devices such as safety pins, separate tapes, a separate tie strap or straps, and/or a separate belt can be used for this purpose. Alternatively or in addition, fastening elements can be incorporated into thechassis 100 to enable a user to apply thediaper 20 to the body of the wearer without, or in conjunction with, any separate fastening devices. Many suitable types of such incorporated fastening elements are well-known, including, for example, tapes, adhesives, adhesive tape tabs, ties, buttons, hooks, loops, snap fasteners, other forms of mechanical fasteners, cohesive patches, etc. These incorporated fastening elements may project laterally outward, i.e., away from thelongitudinal axis 42 beyond one or both of the side edges 137 a and 137 b and/or may project longitudinally outward, i.e., away from thelateral axis 44 beyond one or both of the waist edges 136 and 138 or they may lie entirely inside the edges of thediaper 20. When a laminate backsheet is used and is oriented with the nonwoven disposed exteriorly, some forms of mechanical fasteners that typically require specific mating fastener elements, such as hooks that mate with loops, may be configured to engage with the nonwoven and thereby make the inclusion of the specific mating fastener element unnecessary. - For example, as shown in
FIG. 21 andFIG. 22 , laterally opposingadhesive tape tabs chassis 100 at or adjacent to the side edges 137 a and 137 b of thediaper 20. Theadhesive tape tabs FIG. 21 andFIG. 22 project laterally outward from the respective side edges 137 a and 137 b in theback waist region 38. In use, theadhesive tape tabs FIG. 21 andFIG. 22 may be adhered to theexterior surface 104 of thechassis 100 in thefront waist region 36 to fasten theback waist region 38 to thefront waist region 36 in a back-over-front manner. Alternatively, similar adhesive tape tabs may be attached to thechassis 100 in thefront waist region 36 and used to fasten thefront waist region 36 to theback waist region 38 in a front-over-back manner. Suitable adhesive tapes are available from the 3M Corporation of St. Paul, Minn., U.S.A., under the designation of XMF99121. - Each of the adhesive tape tabs may be formed of two or more layers and different ones of these layers may be attached to different surfaces of the chassis. For example, as shown in
FIG. 21 andFIG. 22 , aninterior layer 114 c of the leftadhesive tape tab 114 a is attached onto theleft side flap 147 a, while anexterior layer 114 d of the leftadhesive tape tab 114 a is attached onto theexterior surface 104 of thechassis 100. Similarly, aninterior layer 114 e of the rightadhesive tape tab 114 b is attached onto theright side flap 147 b, while anexterior layer 114 f of the rightadhesive tape tab 114 b is attached onto theexterior surface 104 of thechassis 100. This form of attachment of adhesive tape tabs to the chassis provides the advantage that each of the interior layer and the exterior layer of each adhesive tape tab is subjected essentially to only a shear force at its attachment to the chassis, rather than being subjected to both shear and peel forces. For example, any tendency of theinterior layer 114 c to peel off of theleft side flap 147 a is counteracted by theexterior layer 114 d acting in tension to prevent theinterior layer 114 c from peeling off. Conversely, any tendency of theexterior layer 114 d to peel off of theexterior surface 104 of thechassis 100 is counteracted by theinterior layer 114 c acting in tension to prevent theexterior layer 114 d from peeling off. The exterior layers of the adhesive tape tabs shown inFIG. 21 andFIG. 22 extend farther toward the longitudinal axis than do the interior layers of the adhesive tape tabs. Alternatively, the interior layers may extend farther toward the longitudinal axis than the exterior layers, or both layers may extend equally far toward the longitudinal axis. If the materials onto which the layers of the adhesive tape tab differ in tensile strength or if the attachment of the adhesive tape tab is relatively more secure on one of the surfaces, it may be desirable that the layer that is attached to the stronger material or that is more securely attached to the surface extend farther toward the longitudinal axis in order to distribute the force carried by the adhesive tape tab disproportionately onto the stronger material or the more secure attachment. - Optionally, a
fastening sheet 116 may be attached onto theexterior surface 104 of thechassis 100 in thefront waist region 36 as shown inFIG. 21 andFIG. 22 . Thefastening sheet 116 shown inFIG. 21 andFIG. 22 lies entirely inside the edges of thediaper 20. Alternatively, two or more discrete fastening sheets may be attached onto the exterior surface of the chassis, instead of a single fastening sheet. For example, two laterally opposing fastening sheets may be attached in locations approximately corresponding to the left and right portions of thesingle fastening sheet 116. When a fastening sheet is provided, the adhesive tape tabs may be adhered to the fastening sheet to fasten theback waist region 38 and thefront waist region 36 together. The fastening sheet may be formed of a material used elsewhere in the diaper, such as a film or a nonwoven. In embodiments in which the chassis is extensible, it is preferred that any fastening sheet also be extensible such that the fastening sheet will not restrict the extensibility of the portion of the chassis onto which it is attached. For example, an extensible nonwoven may be used for the fastening sheet. The fastening sheet serves to distribute the tensile force transmitted by each of the adhesive tape tabs over an area of thebacksheet 26 that is larger than the adhered area of the adhesive tape tab. In addition, when a single fastening sheet such asfastening sheet 116 inFIG. 21 andFIG. 22 is used, the fastening sheet may, itself, bear a portion of the tensile force between the laterally opposing adhesive tape tabs and thereby relieve a portion of the force exerted on the backsheet. Thus, the incorporation of such a fastening sheet may be desirable, for example, in order to make it possible to use a relatively inexpensive and relatively weak material for thebacksheet 26. The fastening sheet may be formed of a material having greater strength than the backsheet. Such a stronger material may be more expensive per unit area than the backsheet, but the fastening sheet may be relatively smaller than the backsheet. Therefore, the total cost of a diaper having a fastening sheet may be less than the total cost of a diaper having a backsheet having sufficient strength for adhesive tape tabs to be adhered directly to the exterior surface of the backsheet. - Exemplary fastening elements in the form of cohesive fastening patches are described in this application and the description of their disposition, configuration, and use is intended to apply to any other type of incorporated fastening element insofar as is practical for each such type of fastening element.
- Exemplary fastening elements in the form of cohesive fastening patches may be formed of an inherently crystalline water-based synthetic elastomer to which a tackifying agent has been added to disrupt the polycrystalline structure and thereby render the elastomer cohesive. Such synthetic cohesive products are available from Andover Coated Products, Incorporated, of Salisbury, Mass., U.S.A. and are described in U.S. Pat. No. 6,156,424 issued on 5 Dec. 2000 in the name of Taylor. A cohesive elastomeric fastening element preferably remains extensible in use. Thus, when applied onto an extensible chassis, such a cohesive elastomeric fastening element may be capable of extending as the extensible chassis extends. As a result, when subjected to the tensile hoop forces typically found at the waist opening of a diaper when the diaper is worn, the area of attachment of two cohesive elastomeric fastening elements to each other may be subject only to a shearing force, rather than being subjected to a peeling force. This behavior may enable the fastening elements to remain cohered even when they are extended because cohesive fastening elements typically exhibit relatively higher resistance to shearing forces than to peeling forces.
- Cohesive fastening patches may be formed by the application of a cohesive material directly onto the chassis or onto a separate substrate that is in turn attached to the chassis. For example, a “hot melt” cohesive material may be applied in its molten state onto a surface and allowed to cool and solidify to form such a patch. The cohesive material may be applied in any of a variety of patterns, such as a continuous film, discrete dots, stripes, polygons, etc., and/or spaced and interconnected geometric elements describing a grid.
- Exemplary cohesive fastening patches are shown incorporated into the chassis in
FIG. 1 ,FIG. 2 ,FIG. 3 ,FIG. 6 ,FIG. 10 ,FIG. 11 ,FIG. 12 ,FIG. 15 ,FIG. 23 , andFIG. 24 . In these exemplary embodiments, acohesive fastening patch 110 a is disposed on the exterior of thechassis 100 in thefront waist region 36 adjacent to theleft side edge 137 a and a laterally opposingcohesive fastening patch 110 b is disposed on the exterior of thechassis 100 in thefront waist region 36 adjacent to theright side edge 137 b. Acohesive fastening patch 120 a is disposed on the interior of thechassis 100 in theback waist region 38 adjacent to theleft side edge 137 a and a laterally opposingcohesive fastening patch 120 b is disposed on the interior of thechassis 100 in theback waist region 38 adjacent to theright side edge 137 b. When thediaper 20 is worn as shown inFIG. 23 andFIG. 24 , the back leftcohesive fastening patch 120 a overlaps the front leftcohesive fastening patch 110 a and the cohesion of these two cohesive fastening patches fastens thefront waist region 36 and theback waist region 38 together at the left side of thediaper 20. Similarly, the back rightcohesive fastening patch 120 b overlaps the front rightcohesive fastening patch 110 b and the cohesion of these two cohesive fastening patches fastens thefront waist region 36 and theback waist region 38 together at the right side of thediaper 20. Thus, the configuration of the cohesive fastening patches shown in these figures is adapted for back-over-front fastening. Alternatively, the front cohesive fastening patches may be disposed on the interior of the chassis in the front waist region and the back cohesive fastening patches may be disposed on the exterior of the chassis in order to adapt the configuration of the cohesive fastening patches for front-over-back fastening. InFIG. 23 andFIG. 24 , the cohesive fastening patches are shown overlapped but not exactly aligned along any of their respective edges only for clarity of illustration and can actually be aligned as desired, e.g., to maximize their areas of overlap. - Alternatively, the cohesive fastening patches may be disposed in a reversible configuration that is adapted to provide the user of the
diaper 20 with both options for fastening, i.e., either back-over-front or front-over-back, according to personal preference. When the cohesive fastening patches are disposed on both the exterior and the interior of thechassis 100, a back cohesive fastening patch may overlap a front cohesive fastening patch or the front cohesive fastening patch may overlap the back cohesive fastening patch and, in either arrangement, the cohesive fastening patches fasten thefront waist region 36 and theback waist region 38 together at the side of thediaper 20. Thus, with this configuration of the cohesive fastening patches, the fastening of thediaper 20 at the sides is reversible so that each side can be fastened in a back-over-front manner or, alternatively, in a front-over-back manner. - Two such reversible configurations of cohesive fastening patches are shown in
FIG. 25 ,FIG. 26 ,FIG. 27 , andFIG. 28 . In the first of these exemplary configurations, acohesive fastening patch 110 a wraps around theleft side edge 137 a and is disposed on both the exterior and the interior of thechassis 100 in thefront waist region 36 adjacent to theleft side edge 137 a. A laterally opposingcohesive fastening patch 110 b wraps around theright side edge 137 b and is disposed on both the exterior and the interior of thechassis 100 in thefront waist region 36 adjacent to theright side edge 137 b. Such a continuous configuration may be desirable, for example, in order to allow the cohesive polymer for each cohesive fastening patch to be applied in a single area that is then folded over when the corresponding folded side flap is formed in a manufacturing process. - In the second exemplary reversible configuration of the cohesive fastening patches, a pair of back
cohesive fastening patches chassis 100. Instead, a back left interiorcohesive fastening patch 120 a and a back left exteriorcohesive fastening patch 120 c are disposed on the respective interior and exterior of thechassis 100 adjacent to theleft side edge 137 a in theback waist region 38. Similarly, a back right interiorcohesive fastening patch 120 b and a back right exteriorcohesive fastening patch 120 d are disposed on the respective interior and exterior of thechassis 100 adjacent to theright side edge 137 b in theback waist region 38. Such a discontinuous configuration may be desirable, for example, in order to allow the cohesive polymer to be applied after the side flaps are formed in a manufacturing process. In general, any or all of the cohesive fastening patches may extend around the side edges 137 a and 137 b or may be discontinuous from the exterior to the interior of thechassis 100. - As an alternative to overlapping cohesive fastening patches to fasten the
front waist region 36 and theback waist region 38 together to encircle the waist and the legs of the wearer, the fastening patches may be disposed on the interior surface of the chassis and may be abutted in a face-to-face arrangement to form a flanged connection in which, for example, a portion of theside edge 137 a in the back waist region and a portion of thesame side edge 137 a in the front waist region are superposed, i.e., unlike an overlapped connection, both of the portions of the side edge are exposed in such a flanged connection. - The exemplary diapers shown in
FIG. 1 ,FIG. 2 ,FIG. 3 ,FIG. 6 ,FIG. 10 ,FIG. 11 ,FIG. 12 ,FIG. 15 ,FIG. 23 , andFIG. 24 include discrete laterally opposing cohesive fastening patches. Alternatively, a single laterally extending cohesive fastening patch may be attached at each of the longitudinally opposing waist regions of the diaper. For example, each such single cohesive fastening patch may extend laterally to approximately the lateral extent that is defined by the laterally distal edges of the discrete cohesive fastening patches shown in these figures. Thus, such a single cohesive fastening patch may have approximately the same extent and be located in approximately the same location as thefastening sheet 116 shown inFIG. 21 andFIG. 22 . - As shown in
FIG. 29 ,FIG. 30 , andFIG. 31 , theabsorbent assembly 200 includes anabsorbent core 250. Theabsorbent core 250 has a laterally extendingfront edge 256 in thefront waist region 36 and a longitudinally opposing and laterally extending backedge 258 in theback waist region 38. Theabsorbent core 250 also has a longitudinally extendingleft side edge 257 a and a laterally opposing and longitudinally extendingright side edge 257 b, both absorbent core side edges extending longitudinally between thefront edge 256 and theback edge 258. Any or all of the respectivefront edge 256, backedge 258,left side edge 257 a, andright side edge 257 b of theabsorbent core 250 may lie inward of the respectivefront edge 236, backedge 238,left side edge 237 a, andright side edge 237 b of theabsorbent assembly 200. For example, in the exemplaryabsorbent assembly 200 shown inFIG. 29 , theabsorbent core 250 has itsleft side edge 257 a andright side edge 257 b located laterally inward of, respectively, theleft side edge 237 a andright side edge 237 b of theabsorbent assembly 200. Alternatively, one or more of the edges of theabsorbent core 250 may coincide with the corresponding edge of theabsorbent assembly 200. For example, in the exemplaryabsorbent assembly 200 shown inFIG. 29 , thefront edge 256 andback edge 258 of theabsorbent core 250 coincide with the respectivefront edge 236 andback edge 238 of theabsorbent assembly 200. - The
absorbent assembly 200 may be attached to thechassis 100 over any part or the whole of the area of theabsorbent assembly 200. Preferably, theabsorbent assembly 200 is attached on itsexterior surface 204 to thechassis 100 in a cruciform attachment pattern, i.e., in an attachment pattern that forms or is arranged in a cross or “+” shape. The cruciform attachment pattern may be contiguous, i.e., all of its portions may be touching or connected throughout the pattern in an unbroken sequence. Alternatively, the cruciform attachment pattern may include detached portions and thereby lack contiguity but still be arranged such that the shape of the overall pattern is a cruciform. For example, a discontiguous cruciform attachment pattern may include a longitudinally extending portion disposed along the longitudinal axis and separate left and right laterally distal portions disposed along or adjacent to the lateral axis and thereby form a cruciform as the shape of the overall pattern. - An exemplary contiguous
cruciform attachment pattern 210 is shown inFIG. 26 ,FIG. 29 ,FIG. 30 , andFIG. 31 . The portions of thechassis 100 that lie outside such a cruciform attachment pattern are not restrained by attachment to theabsorbent assembly 200 and therefore remain extensible. In particular, a relatively narrow longitudinally extendingportion 212 of acruciform attachment pattern 210 like that shown inFIG. 29 andFIG. 31 leaves the majority of the width of thechassis 100 in thefront waist region 36 and in theback waist region 38 freely extensible and thereby allows extension of thechassis 100 in the lateral direction in these regions. A relatively wide laterally extendingportion 214 of acruciform attachment pattern 210 like that shown inFIG. 29 andFIG. 30 prevents the portion of thechassis 100 in thecrotch region 37 to which theabsorbent assembly 200 is attached from shifting relative to theabsorbent assembly 200 in that region. A relatively wide laterally extendingportion 214 of acruciform attachment pattern 210 may also contribute to the effectiveness of the side flaps 147 a and 147 b when theelastic strands proximal edges chassis 100 in thecrotch region 37 were free to shift laterally inward, i.e., toward thelongitudinal axis 42 such that theleft side edge 137 a and/or theright side edge 137 b moved toward thelongitudinal axis 42, the side flaps 147 a and 147 b might easily distort and fail to maintain contact with the body. However, because the relatively wide laterally extendingportion 214 of thecruciform attachment pattern 210 restrains thechassis 100 over a relatively wide portion of the width of thecrotch region 37, the side flaps 147 a and 147 b are better supported at their bases while being lifted by theelastic strands - The
cruciform attachment pattern 210 inFIG. 29 ,FIG. 30 , andFIG. 31 extends laterally from near theleft side edge 237 a to near theright side edge 237 b of theabsorbent assembly 200 at and adjacent to thelateral axis 44, but does not extend laterally to this extent over the full length of theabsorbent assembly 200. Similarly, thecruciform attachment pattern 210 inFIG. 29 ,FIG. 30 , andFIG. 31 extends longitudinally from near thefront edge 236 to near theback edge 238 of theabsorbent assembly 200 at and adjacent to thelongitudinal axis 42, but does not extend longitudinally to this extent over the full width of theabsorbent assembly 200. Alternatively, thecruciform attachment pattern 210 may extend to any or all of the side edges 237 a and 237 b and thefront edge 236 and theback edge 238 of theabsorbent assembly 200. For example, thecruciform attachment pattern 210 may extend laterally from theleft side edge 237 a to theright side edge 237 b of theabsorbent assembly 200, but may extend longitudinally only a part of the distance from thefront edge 236 to theback edge 238 of theabsorbent assembly 200. Within the extent of thecruciform attachment pattern 210, theabsorbent assembly 200 may be attached to thechassis 100 continuously or intermittently. For example, a film of an adhesive may be applied continuously over the entire area of the cruciform attachment pattern and then used to continuously attach the absorbent assembly to the chassis. As an alternative example, an adhesive may be applied discontinuously at and inside the boundaries of the cruciform attachment pattern, such as in the form of dots, stripes, beads, spirals, etc., and then used to attach the absorbent assembly to the chassis. Thecruciform attachment pattern 210 may be disposed symmetrically with respect to either or both of thelongitudinal axis 42 and thelateral axis 44 of thechassis 100. Alternatively, thecruciform attachment pattern 210 may be disposed asymmetrically with respect to either or both of thelongitudinal axis 42 and thelateral axis 44. For example, thecruciform attachment pattern 210 shown inFIG. 29 is disposed symmetrically with respect to thelongitudinal axis 42 and asymmetrically with respect to thelateral axis 44. In particular, thecruciform attachment pattern 210 shown inFIG. 29 is disposed asymmetrically toward thefront waist region 36. Also, the laterally extendingportion 214 of thecruciform attachment pattern 210 may be located distant from thelateral axis 44 and thelongitudinally extending portion 212 of thecruciform attachment pattern 210 may similarly be located distant from thelongitudinal axis 42. In addition, thecruciform attachment pattern 210 may be disposed symmetrically with respect to either or both of the side edges 237 a and 237 b and thefront edge 236 and theback edge 238 of theabsorbent assembly 200. For example, thecruciform attachment pattern 210 shown inFIG. 29 is disposed symmetrically with respect to both the side edges 237 a and 237 b and thefront edge 236 and theback edge 238, i.e., thecruciform attachment pattern 210 shown inFIG. 29 is centered on theabsorbent assembly 200. Alternatively, thecruciform attachment pattern 210 may be disposed asymmetrically with respect to either or both of the side edges 237 a and 237 b andfront edge 236 andback edge 238 of theabsorbent assembly 200, i.e., thecruciform attachment pattern 210 may be disposed off-center on theabsorbent assembly 200. - The
absorbent core 250 may be disposed between a lower covering sheet that is disposed on the exterior face of theabsorbent core 250 in a face-to-face arrangement with theinterior surface 102 of the chassis and an upper covering sheet that is disposed on the interior face of theabsorbent core 250. Such an upper covering sheet and lower covering sheet may be attached together to contain theabsorbent core 250 between them and thereby form theabsorbent assembly 200. For example, in the exemplaryabsorbent assembly 200 shown inFIG. 29 ,FIG. 30 , andFIG. 31 , anupper covering sheet 24 and alower covering sheet 25 are attached together at or adjacent to the side edges 237 a and 237 b of theabsorbent assembly 200 in longitudinally extendingadhesive attachment zones upper covering sheet 24 and thelower covering sheet 25 may be attached together in places other than the side edges 237 a and 237 b of theabsorbent assembly 200, e.g., at or adjacent to the end edges 236 and 238 of theabsorbent assembly 200, or at or adjacent to both the end edges 236 and 238 and the side edges 237 a and 237 b. - The
upper covering sheet 24 is water-permeable and allows liquid waste to pass through to theabsorbent core 250, where the liquid waste is absorbed. Thelower covering sheet 25 may be water-impermeable. However, thelower covering sheet 25 preferably is water-permeable. In embodiments in which both theupper covering sheet 24 and thelower covering sheet 25 are water-permeable, any liquid waste that is deposited onto theupper covering sheet 24 but does not pass through theupper covering sheet 24 to theabsorbent core 250 can flow around an edge of theabsorbent assembly 200 to reach thelower covering sheet 25 and then pass through thelower covering sheet 25 to theabsorbent core 250. - The
upper covering sheet 24 may form theinterior surface 202 of theabsorbent assembly 200 that is intended to be placed against the body of the wearer. Theupper covering sheet 24 preferably is formed of a soft material that will not irritate the skin of the wearer. Many materials that are suitable for a water-permeable covering sheet are well-known in the art, including synthetic nonwovens such as spunbonded or carded polypropylene, polyester, or rayon. Likewise, many materials that are suitable for a covering sheet that is water-impermeable are well-known in the art, including the materials that are suitable for thebacksheet 26. - The
upper covering sheet 24 and thelower covering sheet 25 may extend to the same width and the same length. Alternatively, one or more of the edges of one of the covering sheets may lie distally relative to the respective edge or edges of the other covering sheet. For example, the upper covering sheet may extend longitudinally only to an extent sufficient to cover the absorbent core and the lower covering sheet may extend longitudinally beyond the upper covering sheet toward or to the adjacent waist edge. Such an extended covering sheet may serve to isolate the skin of the wearer from a portion of thebacksheet 26 as may be desirable, for example, when thediaper 20 is worn under conditions in which contact between the skin and a backsheet film could be uncomfortable. - Suitable absorbent materials for the absorbent core are well-known, including cellulose fibers in the form of comminuted wood pulp, which is commonly known as “airfelt”, layers or sheets of natural or synthetic fibrous material, superabsorbent polymer, etc. These absorbent materials may be used separately or in combination. Many known absorbent materials may be used in a discrete form, i.e., in the form of fibers, granules, particles, and the like. Such a discrete form of an absorbent material may be immobilized by an adhesive that attaches the discrete pieces together to form a coherent layer or that attaches the discrete pieces to a substrate layer, such as a covering sheet, or that attaches the discrete pieces both to each other and to the substrate layer.
- Alternatively, the discrete form of an absorbent material may be immobilized in pockets formed by a layer of a thermoplastic material, such as a hot melt adhesive, that intermittently contacts and adheres to a substrate, such as a covering sheet, while diverging away from the substrate at the pockets. Absorbent assemblies having such structures are described in U.S. Patent Application Publications Nos. 2004/0162536 of 19 Aug. 2004 and 2004/0167486 of 26 Aug. 2004. An exemplary
absorbent assembly 200 having such a structure is shown inFIG. 32 . In thisabsorbent assembly 200, theabsorbent core 250 includes particles ofsuperabsorbent polymer 270 that are contained insidepockets 280 formed by alayer 275 of a thermoplastic material. Thisabsorbent core 250 contains no cellulose fibers. Alternatively, theabsorbent core 250 may include both particles of superabsorbent polymer and airfelt and both materials may be contained inside the pockets formed by the layer of the thermoplastic material. As shown inFIG. 32 , thelayer 275 of the thermoplastic material intermittently contacts and adheres to thelower covering sheet 25 at the areas ofattachment 282. Between the areas ofattachment 282, thelayer 275 diverges away from thelower covering sheet 25 to form thepockets 280. Thelayer 275 may have the form of a sheet of fibers of the thermoplastic material through which the liquid waste may pass to the particles ofsuperabsorbent polymer 270 to be absorbed. - In
FIG. 32 , a separateupper covering sheet 24 is shown overlying thelayer 275 of the thermoplastic material. Alternatively, the separateupper covering sheet 24 may be omitted and thelayer 275 in the form of a fibrous sheet may serve as theupper covering sheet 24. As another alternative, two absorbent assemblies each like that shown inFIG. 32 except for the omission of theupper covering sheet 24 may be superposed with one absorbent assembly inverted such that its pockets nest into the recesses at the areas ofattachment 282 of the other absorbent assembly and the respective single covering sheets distally oppose each other. In such a combinedabsorbent assembly 200, the distally opposing single covering sheets may serve respectively as theupper covering sheet 24 and thelower covering sheet 25. - In the exemplary
absorbent assembly 200 shown inFIG. 29 ,FIG. 30 , andFIG. 31 , theupper covering sheet 24 and thelower covering sheet 25 are of the same size, i.e., both theupper covering sheet 24 and thelower covering sheet 25 extend to thefront edge 236 andback edge 238, as well as to theleft side edge 237 a andright side edge 237 b of theabsorbent assembly 200. Alternatively, theupper covering sheet 24 and thelower covering sheet 25 may differ in size. For example, thelower covering sheet 25 may be larger than theupper covering sheet 24 and may be wrapped over the side edges 257 a and 257 b of theabsorbent core 250 onto the interior surface of theabsorbent core 250, where theupper covering sheet 24 and thelower covering sheet 25 may be attached together. Alternatively, in place of a separateupper covering sheet 24 and a separatelower covering sheet 25, a single covering sheet may be wrapped around theabsorbent core 250 and attached to itself to contain theabsorbent core 250. Such a single covering sheet forms an upper layer and a lower layer when wrapped around theabsorbent core 250 and, in general, the description of the separateupper covering sheet 24 andlower covering sheet 25 are intended to apply to such upper and lower layers of a wrapped single covering sheet. - At a minimum, the
absorbent core 250 is contained laterally by the covering sheet or sheets being wrapped around theabsorbent core 250 or attached together at or adjacent to theleft side edge 237 a andright side edge 237 b of theabsorbent assembly 200. For example, in the exemplaryabsorbent assembly 200 shown inFIG. 29 ,FIG. 30 , andFIG. 31 , theupper covering sheet 24 and thelower covering sheet 25 are attached together only in leftadhesive attachment zone 29 a and rightadhesive attachment zone 29 b at or adjacent to the respectiveleft side edge 237 a andright side edge 237 b of theabsorbent assembly 200. In this embodiment, theupper covering sheet 24 and thelower covering sheet 25 cannot be attached directly together at or adjacent to thefront edge 236 andback edge 238 because theabsorbent core 250 extends the full length of theabsorbent assembly 200, i.e. thefront edge 256 andback edge 258 of theabsorbent core 250 coincide with the respectivefront edge 236 andback edge 238 of theabsorbent assembly 200. In such an embodiment, the upper and lower layers of the covering sheet or sheets may each be attached to theabsorbent core 250 at or adjacent to thefront edge 256 andback edge 258 of theabsorbent core 250 to form a sandwich. In addition, a sealing agent may be applied at or adjacent to thefront edge 256 andback edge 258 of theabsorbent core 250 to contain any fibers or particles that might otherwise escape theabsorbent core 250. Alternatively, instead of being contained only laterally by the covering sheet or sheets, theabsorbent core 250 may additionally be contained longitudinally by the upper and lower layers of the covering sheet or sheets being attached together at or adjacent to thefront edge 236 andback edge 238 of theabsorbent assembly 200. - The disclosures of all patents, patent applications and any patents which issue thereon, as well as any corresponding published foreign patent applications, and all publications listed and/or referenced in this description, are hereby incorporated herein by reference. It is expressly not admitted that any of the documents or any combination of the documents incorporated herein by reference teaches or discloses the present invention.
