Detailed Description

An embodiment of the absorbent article according to the present invention will be described in detail with reference to fig. 1 to 5. However, the present invention is not limited to the embodiment of the present embodiment.

In the description and claims, the "longitudinal direction" refers to a direction from the front portion side of the absorbent article to the rear portion side via the crotch portion, and the "width direction" refers to a direction perpendicular to the longitudinal direction.

First, an embodiment in which the present invention is applied to an open-type disposable diaper will be described below.

< major constitution of diaper >

Fig. 1 is a perspective view of an example of the appearance of a diaper according to an embodiment of the present invention, as viewed from the front side. The diaper 10 of the present embodiment is an open-type disposable diaper, and includes a front body portion 10F, a back body portion 10R, and a crotch portion 10C connecting the front body portion 10F and the back body portion 10R. Further, a waist circumferential opening 10W is formed in a portion surrounding the waist of the wearer when worn by the front body 10F and the rear body 10R. Similarly, a pair of left and right leg hole portions 10L are formed to surround the thigh portions of the wearer's legs by the lower end portions and the crotch portion 10C of the front body portion 10F and the rear body portion 10R.

When worn, the front body 10F is positioned on the abdomen side of the wearer, and the rear body 10R is positioned on the back side of the wearer. When worn, the crotch unit 10C covers the crotch of the wearer, and the legs of the wearer pass through the pair of left and right leg hole openings 10L. Therefore, the leg hole openings 10L are located at a certain position from the base of the legs to the thigh band of the wearer.

The imaginary line P extends from the abdomen side to the back side in the central part of the diaper, passing through the crotch part. Specifically, for example, when the waist side of the diaper is defined as the upper side and the crotch side is defined as the lower side, the imaginary line P extends in the vertical direction along the diaper front surface and also extends in the vertical direction on the back side via the crotch portion.

A pair of left and right fastening tapes (first joining members) 10A that are overlapped with and joined to the left and right end edges of the front body 10F when worn, and that can form leg hole openings 10L, are bonded to the left and right end edges of the back body 10R of the cover sheet 11 positioned outside the diaper 10. The fastening tape 10A is connected to the front patch (the 2 nd joining member) 10B bonded to the cover sheet 11 of the front body portion 10F in a manner capable of being repeatedly peeled. In the present invention, the fastening tape 10A and the front patch 10B can function as a mechanical fastener. As shown in fig. 3, the end edge portion of the front patch 10B on the crotch portion 10C side is disposed close to the end portion of the absorbent body 13 on the front body portion 10F side. In the present invention, the longitudinal end of the absorbent member 13 may be extended to the vicinity of the end on the front body 10F side of the diaper 10, and the front patch 10B and the absorbent member 13 may be arranged so as to overlap in the thickness direction of the diaper 10. With this configuration, abdominal leakage (ventral leakage) can be reduced.

Fig. 2 is a schematic exploded perspective view of the diaper 10 shown in fig. 1, and fig. 3 is a plan view of the diaper 10 in an extended state as viewed from the topsheet 14 side in one embodiment of the present invention. For convenience of explanation, the absorbent member 13 of fig. 2 and the diaper 10 of fig. 3 are each shown partially cut away.

As shown in fig. 2, the diaper 10 of the present embodiment has a laminated structure in which a cover sheet 11 formed of a thin nonwoven fabric for obtaining a good texture, a liquid-impermeable back sheet (back sheet) 12, an absorber 13, a liquid-permeable top sheet (front sheet) 14, and a pair of side sheets 15 are sequentially stacked from the outside (non-skin surface side).

Fig. 4 is a sectional view taken along the direction IV-IV in fig. 3, and fig. 5 is a sectional view taken along the direction V-V in fig. 3.

In the present embodiment, as shown in fig. 3 to 5, the absorbent body 13 has a region in which a plurality of compressed concave portions 20 are formed. That is, a plurality of recesses 20 are formed in a part of the recess forming region. In the present embodiment, the absorbent body 13 has the concave portions 20 formed in a lattice shape. As shown in fig. 3 to 5, the formation of the concave portion 20 facilitates the bending of the concave portion 20, thereby improving the fit of the diaper 10. Further, by continuously forming the concave portion 20, air can pass through the ventral side or the dorsal side, and air permeability can be ensured. In addition, the discharged body fluid can be rapidly diffused, and the absorbent 13 can be efficiently absorbed by using the absorbent 13 as a whole.

In the present invention, the plurality of concave portions 20 is a concept including a plurality of physically continuous concave portions formed by overlapping a plurality of concave portions 20 as constituent units, in addition to a plurality of individual concave portions 20 each of which is physically discontinuous. Examples of the above-mentioned constituent unit include a straight line and a continuous curve having no meandering (angle) in the middle thereof, but are not limited thereto.

For example, an adhesive is applied to the surface of the top sheet 14 in contact with the absorbent body 13, and the concave portions 20 are provided by pressing the laminate (hereinafter also referred to as "absorbent portion") of the absorbent body 13 and the top sheet 14. The pressing is carried out, for example, by means of an embossing roller. Thus, the top sheet 14 is integrally connected to the absorbent body 13 by engaging with the entire recess 20 from the bottom surface (bottom wall) to the wall surface (side wall) of the recess 20. The thickness of the bottom portion of the concave portion 20 (the thickness of the absorbent portion) formed by the top sheet 14 and the absorbent body 13 is preferably about 1/2 to 1/7 of the thickness without being pressed. More preferably about 1/4-1/7. According to this configuration, since the top sheet 14 is formed integrally with the absorbent body 13, the top sheet 14 is firmly connected to the absorbent body 13, and the top sheet 14 is less likely to peel off, and even when the absorbent body 13 swells after urination, the top sheet 14 is in a state of following the groove, and the groove is maintained.

In the present embodiment, the absorbent body 13 is provided with a concave portion forming region in which a plurality of concave portions 20 formed by compression are formed and a concave portion non-forming region in which no concave portion 20 is formed. According to this configuration, the recess non-formation region functions as a bank and can block (or weaken) the body fluid that has passed through the recess 20, and therefore, lateral leakage can be prevented. In the absorbent article 10 of the present embodiment, the absorbent body 13 is formed with the concave portions 20 in a lattice shape, but the absorbent article of the present invention is not limited to this, and it is also permissible that no concave portions 20 are formed at all in the absorbent body 13. In the absorbent article of the present invention, the concave portions 20 formed in the absorbent body 13 are not limited to the lattice shape, and concave portions formed in a vertical stripe shape in the longitudinal direction, concave portions formed in a horizontal stripe shape in the width direction, intermittently provided concave portions, and the like may be employed, and concave portions having various shapes may be employed as long as the effects of the present invention are exhibited.

As shown in fig. 2 and 3, a pair of notches 11N serving as leg hole openings 10L are formed on both left and right sides of the crotch portion 10C of the cover sheet 11. A pair of rubber threads 16 for forming gathers around the legs are bonded in a stretched state between the cover sheet 11 and the pair of side sheets 15. In the present invention, a plurality of holes that can be ventilated may be formed in the cover sheet 11. According to this embodiment, when the diaper 10 is viewed from the non-skin surface side, the colored fastening tape 10A and the stretchable member 10D, which will be described later, are easily visually recognized through the plurality of holes. As the plurality of holes, a plurality of holes may be formed in a vertical stripe pattern intermittently in the cover sheet 11 along the longitudinal direction of the diaper 10. In the present invention, the transmittance of the cover sheet 11 can be increased, and according to this configuration, the colored fastening tape 10A and the stretchable member 10D can be easily visually recognized as in the above-described effect.

The top sheet 14 is made of a liquid-permeable nonwoven fabric or the like. The back sheet 12 has moisture permeability and is attached to the skin surface side of the cover sheet 11 (for example, by an adhesive such as a hot melt adhesive), the absorbent body 13 is disposed between the back sheet 12 and the top sheet 14, and the top sheet 14 is attached to the back sheet 12 via the absorbent body 13 (for example, by an adhesive such as a hot melt adhesive).

In addition, an extensible member 10D that extends in the width direction of the back sheet 12 and forms a waist gather that gives a proper wearing feeling to the wearer around the waist is connected in an extended state to a region of the back sheet 12 corresponding to the upper end of the back body portion 10R. In the present invention, the stretchable member 10D is, for example, a polyurethane elastic sheet formed by forming polyurethane foam into a sheet shape, and has a thickness approximately equal to the thickness of the absorbent body 13. The valley (thin-walled region 1 described later) formed between the stretchable member 10D having such a thickness and the absorbent body 13 allows the user to easily recognize which side of the diaper 10 is the back side and which side is the abdomen side. In the present invention, the stretchable member 10D may be an elastic sheet made of, for example, a rubber filament, a stretchable film, or a polyurethane foam. In the present invention, the extensible member 10D is preferably thick and sheet-shaped, and according to this configuration, the configuration of the 3 rd thin region described later can be easily grasped by the touch. In the present embodiment, the stretchable member 10D is a polyurethane elastic sheet formed by forming polyurethane foam into a sheet shape, and has a thickness approximately equal to the thickness of the absorbent body 13. In the present invention, the thin region (the 2 nd thin region T2 described later) between the longitudinal end portion on the front body portion 10F side of the diaper 10 and the longitudinal end portion on the front body portion 10F side of the absorbent body 13 and the thin region (the 3 rd thin region T3 described later) between the longitudinal end portion on the back body portion 10R side of the diaper 10 and the longitudinal end portion on the waist portion side of the extensible member 10D are configured such that the structures of the sheets forming the respective thin regions are different (for example, a structure in which the manufacturing method of the nonwoven fabric is different (a structure in which one is an air-permeable nonwoven fabric or one is a long fiber nonwoven fabric, or the like), a structure in which the embossing pattern, the bonding area ratio, the thickness of the nonwoven fabric fibers, or the like are different), according to this configuration, the user can grasp the difference in configuration by touch, and as a result, it is easy to recognize which side of the diaper 10 is the back side and which side is the abdomen side. The details will be described later. An example of the polyurethane constituting the elastic member 10D is a flexible polyurethane foam.

In the present embodiment, as shown in fig. 3, a pair of colored fastening tapes 10A and colored extensible members 10D, which will be described later, are arranged along the width direction of the diaper 10. That is, a pair of fastening tapes 10A are disposed in the extending direction of the stretchable member 10D in the rear body portion 10R of the diaper 10. According to this configuration, when the user visually recognizes the colored stretch member 10D, the pair of colored fastening tapes 10A can be quickly found by directly looking in the width direction of the diaper 10, and therefore, the time taken to wear the diaper 10 can be shortened.

The absorbent body 13 of the present embodiment located below the top sheet 14 is formed by covering an absorbent core 17 mainly composed of pulp and SAP with a covering member (core covering material) 18 such as tissue paper or nonwoven fabric. The seam formed by wrapping the absorbent core 17 with the covering member 18 is formed to extend in the longitudinal direction on the upper surface of the absorbent body 13, as shown in fig. 2, for example. In the present invention, the form of the formation of the seam is not limited to this. The absorber 13 of the present embodiment is elongated so as to straddle the front, crotch, and back. The absorber 13 is divided into a back portion, a crotch portion, and a front portion. Here, if the front-back (up-down) direction is defined as the front-back direction from the front body portion to the rear body portion, and the direction orthogonal thereto is defined as the left-right direction, the absorber 13 of the present embodiment is a rectangle having different front-back (up-down) left-right lengths (in fig. 2 and 3, the front-back (up-down) length is longer than the left-right length). The shape of the absorbent body 13 of the present embodiment is not limited to this, and includes various shapes such as a substantially square shape having a length that is the same in the front-rear (up-down) left-right direction, a rounded shape at the front-rear (up-down) end, an oval shape extending in the front-rear (up-down) direction, and a circular shape. In the crotch portion of the absorber 13, a pair of notches having an arc shape may be formed so as to correspond to the pair of leg hole openings 10L. In addition, although the absorbent body 13 wrapped with the wrapping member 18 is used in the diaper 10 of the present embodiment, the absorbent article of the present invention may use the absorbent core 17 that is not wrapped with the wrapping member 18.

The top sheet 14 in the present embodiment includes a pair of hydrophobic side sheets 15 forming three-dimensional gathers at both left and right side edges in the width direction. The pair of side sheets 15 are members that rise along both left and right side edges of the absorbent body 13 when worn, and prevent lateral leakage of discharged body fluid. A notch 15N is formed in the outer edge of the pair of side sheets 15 in the same shape as the pair of notches 11N of the cover sheet 11. The rubber threads 19, which are three-dimensional gather stretch materials, are arranged in an extended state in a state in which the inner edge portions of the pair of side sheets 15 are folded back toward the absorbent body 13 and held. The pair of side sheets 15 rise in the direction of contact with the skin of the wearer when the rubber thread 19 contracts. The three-dimensional gathers can be formed by a known structure used in conventional disposable diapers. For example, the stretched three-dimensional gather stretch material may be sandwiched between layers of the waterproof sheet and fixed.

< thin wall region >

< 1 st thin wall region >

In the present invention, as described above, as a configuration for facilitating the front-rear separation of the diaper 10 by the sense of touch, by providing the thin region having a thickness smaller than the thickness of the absorber 13 and the thickness of the extensible member 10D in the rear body portion 10R, the user can grasp the front-rear separation of the diaper 10 by the sense of touch, and as a result, the front-rear separation of the diaper 10 by the sense of touch can be facilitated.

In the present embodiment, as shown in fig. 5, a 1 st thin region T1 having a thickness D1 smaller than the thickness de of the stretchable member 10D and the thickness da of the absorbent body 13 is provided between the stretchable member 10D and the absorbent body 13 in the longitudinal direction of the diaper 10. According to this configuration, if the 1 st thin region T1 exists between the thick stretchable member 10D and the thick absorbent body 13 on the back body 10R side of the diaper 10, the user can grasp it, and therefore, the front and back of the diaper 10 can be easily distinguished. That is, when the vicinity of both longitudinal end portions of the diaper 10 is grasped with fingers and the fingers are moved toward each other at both end portions of the absorbent body 13, the back side is caught (because the valley generated between the stretchable member 10D and the absorbent body 13, that is, the 1 st thin region T1 is caught with fingers), and it can be easily grasped that there is a difference between the front and back of the diaper 10.

In the present invention, the top sheet 14 may be provided with an embossed pattern having a convex shape protruding toward the skin surface side so as to extend in the longitudinal direction. According to this configuration, when the diaper 10 is touched, the fingers can be easily moved along the 3D emboss of the top sheet 14, and the valleys described above can be easily reached, and the valleys can be easily grasped with the fingers.

In the present invention, as described above, a plurality of holes that can be ventilated may be formed in the cover sheet 11 in a vertical stripe pattern intermittently along the longitudinal direction of the diaper 10, and according to this configuration, as in the 3D embossing, when the diaper 10 is touched, fingers are easily moved along the plurality of holes formed along the longitudinal direction of the top sheet 14, and the above-described valleys are easily reached, and the valleys are easily grasped with the fingers.

In addition, in the present embodiment, the 1 st thin region T1 is a configuration of only 3 sheets of the top sheet 14, back sheet 12, and cover sheet 11 as shown in fig. 5, but the present invention is not limited to this, and an absorbent body having a thickness smaller than that of the absorbent body 13 may be provided separately from the absorbent body 13.

In the present invention, the length L1 in the longitudinal direction of the absorbent article 10 of the 1 st thin-walled region T1 is preferably 5mm or more and 20mm or less, from the viewpoint of exerting the effects of the present invention. When the length L1 is less than 5mm, it is difficult to grasp with a finger, and when the length L1 is greater than 20mm, it is difficult to recognize with a finger as a valley as described above.

It is preferable that the thickness da of the absorbent body 13 is 1.5mm to 4.0mm, the thickness de of the stretchable member 10D is 0.5mm to 1.5mm, and the thickness D1 of the 1 st thin region is 0.3mm to 0.5mm, in order to exhibit the effects of the present invention.

Since the 1 st thin-walled region T1 is less rigid than the absorbent body 13 and tends to contract, wrinkles (for example, a pleat or bellows-like portion) are formed in the 1 st thin-walled region T1 by the influence of the extensible member 10D. That is, in the present embodiment, the 1 st thin region T1 is a region where wrinkles are formed when the extensible member 10D is not extended, that is, a region where wrinkles are formed in a state where the extensible member 10D is not extended in the width direction (natural state/free state). In this case, since a different texture can be obtained in the region where the wrinkles are formed from the other region where no wrinkles are formed, the front and rear sections of the diaper can be easily distinguished by recognizing the difference in texture.

In order to form the gathers, a certain degree of space is required between the stretchable member 10D and the absorbent body 13, and the length L1 in the longitudinal direction of the 1 st thin-walled region T1 is preferably 5mm or more in order to form the gathers.

< 2 nd and 3 rd thin-walled regions >

In addition, in the present embodiment, as a configuration for facilitating the front-rear separation of the diaper 10 by the sense of touch, the 2 nd thin-walled region and the 3 rd thin-walled region having a thickness smaller than the thickness of the absorbent body 13 and the thickness of the extensible member 10D are provided in the front body portion 10F and the rear body portion 10R, respectively, and the configuration of the sheet forming the thin-walled region of the diaper 10 (for example, the length of the thin-walled region in the longitudinal direction of the diaper 10) is made different between the front body portion 10F side and the rear body portion 10R side, so that the user can grasp the difference in the configuration (for example, the length of the thin-walled region in the longitudinal direction of the diaper 10) by the sense of touch, and as a result, the front-rear separation of the diaper 10 by the sense of touch can be facilitated.

In the present embodiment, as shown in fig. 5, a 2 nd thin region T2 having a thickness D2 smaller than the thickness de of the stretchable member 10D and the thickness da of the absorbent body 13 is provided between the longitudinal end of the diaper 10 on the front body 10F side and the absorbent body 13 in the longitudinal direction of the diaper 10. Specifically, as shown in fig. 5, the 2 nd thin-walled region T2 is provided between the longitudinal end portion on the front body 10F side of the diaper 10 and the longitudinal end portion on the front body 10F side of the 2 nd joining member 10B in the longitudinal direction of the diaper 10. In the present embodiment, as shown in fig. 5, a 3 rd thin region T3 having thicknesses D31 and D32 thinner than the thickness de of the stretchable member 10D and the thickness da of the absorber 13 is provided between the longitudinal direction end portion of the diaper 10 on the back 10R side and the stretchable member 10D in the longitudinal direction of the diaper 10. Further, a length L2 in the longitudinal direction of the 2 nd thin-walled region T2 is different from a length L3 in the longitudinal direction of the 3 rd thin-walled region T3. In the present embodiment, as shown in fig. 5, the length L2 in the longitudinal direction of the 2 nd thin-walled region T2 is shorter than the length L3 in the longitudinal direction of the 3 rd thin-walled region T3. The user can recognize by touch that there is a significant difference between the length L2 and the length L3, and for example, the thickness of the 2 nd thin-wall region T2 and the 3 rd thin-wall region T3 is grasped with the thumb and forefinger, and therefore, the front and rear of the diaper 10 can be easily distinguished. That is, by providing the end portions that are pinched more when the diaper 10 is unfolded with regions having different lengths, it is possible to recognize that there is a difference between before and after (there is a difference between before and after). In the present invention, a scheme is also permissible in which the average value of the length L2 in the longitudinal direction of the 2 nd thin-wall region T2 is different from the average value of the length L3 in the longitudinal direction of the 3 rd thin-wall region T3.

In the present invention, the length L2 in the longitudinal direction of the 2 nd thin-walled region T2 and the length L3 in the longitudinal direction of the 3 rd thin-walled region T3 are preferably 30mm or less, respectively, and according to this configuration, the length within the 1 st joint of the thumb can be set, the ventral end or the dorsal end can be easily grasped by the thumb abdomen of the thumb, and the difference in the configuration between the 2 nd thin-walled region T2 and the 3 rd thin-walled region T3 can be easily recognized.

In the present invention, the number of members constituting the 2 nd thinned region T2 and/or the 3 rd thinned region T3 of the diaper 10 may be smaller on the waist side than on the crotch side of the absorbent article 10. In the present embodiment, as shown in fig. 5, of the members constituting the 3 rd thin-walled region T3 of the diaper 10, the number of members on the waist side of the diaper 10 is 1 (only the cover sheet 11) and the thickness is d32, whereas the number of members on the crotch side of the diaper 10 is 3 (the cover sheet 11, the back sheet 12, and the top sheet 14) and the thickness is d31, and the members on the waist side of the diaper 10 are smaller than the number of members on the crotch side and are also thinner. On the other hand, in the present embodiment, as shown in fig. 5, of the members constituting the 2 nd thin-walled region T2 of the diaper 10, the number of members on the waist portion side and the number of members on the crotch portion side of the diaper 10 are both 1 (only the cover sheet 11), and the number of members on the waist portion side and the number of members on the crotch portion side of the diaper 10 are equal. According to these configurations, the user can recognize the difference in the number of members (or the thickness of the members) constituting the 2 nd thin-walled region T2 and the number of members (or the thickness of the members) constituting the 3 rd thin-walled region T3 by tactile sensation, and therefore, the front and rear of the diaper 10 can be easily distinguished. Further, by making the length of the thick portion (hard portion) different between the 2 nd thin-wall region T2 and the 3 rd thin-wall region T3 as shown in fig. 5, the difference between the two can be recognized more reliably. In the present embodiment, the number of members constituting the 2 nd thin-walled region T2 is 1, but in the present invention, the number of members constituting the 2 nd thin-walled region T2 may be 2 or more. In short, the sheet configuration may be different between the 2 nd thin-wall region T2 and the 3 rd thin-wall region T3, and the user can recognize the difference.

The difference between the length L2 of the 2 nd thin-walled region T2 in the longitudinal direction and the length L3 of the 3 rd thin-walled region T3 in the longitudinal direction is preferably 10mm or more and 30mm or less in order to exhibit the effects of the present invention. It is preferable that the thickness d2 of the 2 nd thin-walled region is 0.2mm to 0.3mm, the thickness d31 of the 3 rd thin-walled region is 0.3mm to 0.5mm, and the thickness d32 of the 3 rd thin-walled region is 0.2mm to 0.3mm, in order to exhibit the effects of the present invention.

The structure of the sheet forming the 2 nd thin-walled region T2 and the structure of the sheet forming the 3 rd thin-walled region T3 may be different as follows. The difference in the structure of the sheet can be realized, for example, by: (i) one of the sheet forming the 2 nd thin-wall region T2 and the sheet forming the 3 rd thin-wall region T3 is made of an air-permeable nonwoven fabric or a filament nonwoven fabric (for example, one of the sheets is made of an air-permeable nonwoven fabric and the other is made of a filament nonwoven fabric), (ii) the structure of embossing applied to the sheet forming the 2 nd thin-wall region T2 and the structure of embossing applied to the sheet forming the 3 rd thin-wall region T3 are different from each other (for example, the embossing pattern, the size, shape, height, depth, and/or the like of the embossing are different from each other), (iii) in the case of a sheet forming the 2 nd thin-wall region T2 and a sheet forming the 3 rd thin-wall region T3 each being a sheet laminate in which a plurality of sheets are bonded and laminated, the bonding area ratio of the sheet laminate of the 2 nd thin-wall region T2 is different from the bonding area ratio of the sheet laminate of the 3 rd thin-wall region T3, (iv) the thickness of the nonwoven fabric fibers constituting the sheet forming the 2 nd thinned region T2 and the thickness of the nonwoven fabric fibers constituting the sheet forming the 3 rd thinned region T3 were made different from each other. Here, the bonded area ratio is a ratio of an area where fibers of the nonwoven fabric are partially thermally bonded to each other. According to the above configurations (i) to (iv), the feeling of touch can be made different between the 2 nd thin region T2 and the 3 rd thin region T3, and therefore, the front and rear of the diaper can be further easily distinguished.

< colors of fastening band and stretchable Member >

In the present embodiment, the fastening tape 10A and the stretchable member 10D having different colors from the surroundings can be visually distinguished also in the rear body portion 10R of the diaper 10, thereby facilitating the front-rear separation of the diaper 10.

< color of fastening tape >

In the present embodiment, the pair of fastener tapes 10A are colored in a 2 nd color (for example, green) different from a 1 st color (for example, white) of the periphery of the diaper 10 to which the pair of fastener tapes 10A are attached. As shown in fig. 3, the fastening tape 10A is composed of a hook portion 101 and a hook receiver 102 disposed so that the hook portion 101 is disposed at one end 102a thereof and the other end 102b thereof is sandwiched by the constituent members (in the present embodiment, the side sheet 15 and the cover sheet 11) of the diaper 10, and the hook portion 101 and/or the hook receiver 102 are colored in the 2 nd color. With this configuration, it is possible to recognize at a glance which of the front body 10F and the back body 10R of the diaper 10 is, that is, which of the front side and the back side of the diaper 10 is the abdominal side, and as a result, the time and effort for wearing the diaper 10 can be reduced. Further, since it is possible to quickly grasp at which position of the diaper 10 the hook portion 101 connected to the front patch 10B is attached, the diaper 10 can be worn vigorously (or worn by another person).

In general, the absorbent article has a white color as a whole from the viewpoint of giving a clean feeling to a person, but it is understood that the absorbent article in this case is not easily visually distinguished from the front and back. In particular, since many members having a white color are provided on the skin surface side of the absorbent article, it is considered that it is further difficult to distinguish them. In the present embodiment, the diaper 10 has a portion other than the fastening tape 10A and the below-described stretch member 10D with the same color (for example, white), and the fastening tape 10A and the below-described stretch member 10D are colored in a color different from the color of the portion. Thus, even when the entire diaper 10 is viewed from the skin surface side, the user can see through the fastening tape 10A and the stretchable member 10D from the cover sheet 11 and the top sheet 14, and thus can grasp the back side of the diaper 10 at a glance.

In the present embodiment, one of the components that sandwich the other end 102b of the hooking support 102 is the side sheet 15, the other end 102b of the hooking support 102 is colored in the 2 nd color, and the other end 102b of the hooking support 102 and the side sheet 15 are arranged so that the coloring of the other end 102b of the hooking support 102 can be visually confirmed through the side sheet 15. According to this configuration, immediately before wearing, when the diaper 10 is viewed from the skin surface side, it can be quickly recognized which side is the abdomen side and which side is the back side, and therefore, the diaper 10 can be worn vigorously (or worn by another person). In the present invention, even if the top sheet 14 is used instead of the side sheet 15 having the above-described configuration, one of the components that sandwich the other end portion 102b of the hook receiver 102 is the top sheet 14, and the other end portion 102b of the hook receiver 102 and the top sheet 14 are arranged so that the coloring of the other end portion 102b of the hook receiver 102 can be visually confirmed through the top sheet 14, the same effect is exhibited.

< color of the stretching Member >

In the present embodiment, as described above, the stretchable member 10D is colored in the 4 th color (for example, green) different from the 3 rd color (for example, white) of the periphery of the absorbent article 10 to which the stretchable member 10D is attached. With this configuration, it is possible to recognize at a glance which of the front body 10F and the back body 10R of the diaper 10 is, that is, which of the abdomen and the back of the diaper 10 is, and as a result, the time and effort for wearing the diaper 10 can be reduced.

In the present embodiment, the extensible member 10D is a polyurethane sheet as described above. With this sheet-like structure, the area to be colored becomes large, and the whole waist gather area can be visually recognized, so that the front and back of the diaper 10 can be quickly distinguished.

In the present embodiment, the 4 th color colored in the extensible member 10D and the 2 nd color colored in the fastening band 10A are the same color. With this configuration, the stretchable member 10D and the fastening tape 10A located in the vicinity thereof can be visually recognized as one unit, and therefore, the front and rear sections of the diaper 10 can be instantly distinguished.

In the present embodiment, the 1 st color is a color of the diaper 10 on the skin surface side in the periphery where the pair of 1 st joining members 10A are attached, the 3 rd color is a color of the diaper 10 on the skin surface side in the periphery where the stretchable member 10D is attached, and the 1 st and 3 rd colors are white. With this configuration, the presence of the fastening band 10A having the 2 nd color and the stretchable member 10D having the 4 th color can be clearly grasped.

< part changing the number of Components >

In the present embodiment, as described above, in the 3 rd thinned region T3, the number of components of the sheet to be configured changes from the longitudinal end portion of the diaper 10 toward the crotch portion 10C, and the 3 rd thinned region T3 functions as a component number changing portion.

In the present embodiment, as shown in fig. 5, in the 3 rd thin-walled region T3 (the number-of-components changing portion): the number of components of the sheets to be configured decreases from the crotch portion 10C side toward the longitudinal end of the diaper 10, and gradually softens toward the longitudinal end; on the other hand, the number of components of the configured sheet increases from the longitudinal end of the diaper 10 toward the crotch portion 10C, and gradually increases toward the crotch portion 10C, thereby increasing the stiffness. With this configuration, the longitudinal end portion side is soft, and therefore a gap is likely to be formed between the diaper 10 and the skin (not in close contact with the skin), and air permeability can be improved. In addition, in general, if the longitudinal end portion side of the diaper 10 is too soft, the longitudinal end portion side of the diaper 10 is curled up, and for example, the contact area with pants worn on the diaper 10 increases, so that a phenomenon in which the diaper 10 is detached together when the pants are detached occurs, and in the present embodiment, the number of components of the stepwise sheets toward the crotch portion 10C increases, and the thickness and the rigidity increase, so that it is possible to make it difficult to cause this phenomenon. In the present invention, the 3 rd thin-wall region T3 is not limited to the above configuration.

The configuration of the number-of-components changing portion may be adopted in the region including the 2 nd thin-walled region T2 on the front body portion 10F side. In the above embodiment, as shown in fig. 5, the following 3 regions are provided in order from the longitudinal end portion on the front portion 10F side of the diaper 10 between the longitudinal end portion on the front portion 10F side of the absorbent body 13 and the longitudinal end portion on the front portion 10F side of the diaper 10: only the region of 1 layer of the cover sheet 11 (the 2 nd thin wall region T2); 2 nd bonding member (front patch) 10B and cover sheet 11; the front patch 10B, the cover sheet 11, the back sheet 12 and the top sheet 14 are provided in 4-layer regions, but these structures are provided, for example, in the order of the 1 st region of 2 layers of the inner cover sheet and the top sheet 14 from the longitudinal end of the diaper 10 on the front body 10F side; the 2 nd region of the 3 layers of the outer cover sheet, inner cover sheet, topsheet 14; the front patch 10B, the outer cover sheet, the inner cover sheet, and the 3 rd region of the 4 layers of the top sheet 14, which is the 3 rd region, can function as the component number changing portion. With this configuration, similarly to the effect obtained by the 3 rd thin region T3, in the 1 st to 3 rd sheet regions (member number changing portions), the number of members of the sheets constituting decreases from the crotch portion 10C side toward the longitudinal end portion of the diaper 10 and becomes gradually soft toward the longitudinal end portion, while the number of members of the sheets constituting increases from the longitudinal end portion of the diaper 10 toward the crotch portion 10C side and becomes gradually thicker toward the crotch portion 10C side, thereby increasing the rigidity. With this configuration, as with the effect obtained by the 3 rd thinned region T3, the longitudinal end portion sides are soft, so that a gap is likely to be formed between the diaper 10 and the skin (not in close contact with the skin), and air permeability can be improved. In addition, with this configuration, similarly to the effect obtained by the 3 rd thin region T3, since the number of components of the diaper increases stepwise toward the crotch portion 10C side, the thickness increases, and the rigidity increases, it is possible to make it difficult to cause a phenomenon in which the diaper 10 is detached together when the pants are taken off. Further, according to this configuration, the ventilation property is ensured by providing a soft region (region which is easily opened) at the longitudinal end of the diaper 10, and the diaper 10 can be prevented from being rolled up at all on the longitudinal end side of the diaper 10 as compared with the front patch 10B by providing a hard region (region which is easily pulled along the skin) between the soft region and the front patch 10B. Further, according to this configuration, since the diaper is folded at the boundary between the 1 st panel region and the 2 nd panel region and is not easily folded at the boundary between the 2 nd panel region and the 3 rd panel region, the diaper 10 can be prevented from coming off together with the pants by absorbing the force applied when the pants are worn and taken off, while ensuring air permeability by folding only a sufficient amount necessary for the diaper. Further, according to this configuration, for example, when an infant wearing the diaper 10 has made the waist-side end of the diaper 10, the sheet located at the waist-side end is folded at the boundary between the 1 st sheet region and the 2 nd sheet region and the boundary between the 2 nd sheet region and the 3 rd sheet region, and therefore, it is possible to prevent the diaper 10 from being displaced by the hand entering the inside of the diaper 10 (the fixed position by the front patch 10B and the waist gather and/or the crotch 10C side thereof).

The length of the diaper 10 in the longitudinal direction of the 1 st panel region and the 2 nd panel region is preferably 5mm to 15mm, respectively. If the length is less than 5mm, the sheet is less likely to bend at the boundary between the 1 st and 2 nd sheet regions, and the above-described effects are less likely to be exhibited. On the other hand, if the length is greater than 15mm, the friction (contact area) with the pants increases, and the diaper 10 is likely to be displaced as the pants are put on and taken off. The sum of the lengths of the diaper 10 in the longitudinal direction of the 1 st and 2 nd sheet regions is preferably 25mm or less. If the total length is greater than 25mm, the 1 st and 2 nd regions will roll over together, and there is a possibility that the diaper 10 will fall off together with the pants.

In the present invention, at least the topsheet 14 and/or the (outer, inner) cover sheet 1, which is a material constituting the 2 nd sheet region, may be provided with a longitudinal reinforcing portion formed by embossed portions, bonded regions, and the like extending in the longitudinal direction of the diaper 10. The reinforcing portion may be formed by 3D embossing on the top sheet 14 in the longitudinal direction or by forming a groove in the cover sheet 11 in the longitudinal direction. According to this structure, the diaper 10 is prevented from falling off together with pants because the diaper is hard to be folded, and the 1 st region and the 2 nd region are hard to be rolled up together.

In the present invention, the skin surface side of the 1 st region and/or the 2 nd region may have a smaller static friction coefficient than the non-skin surface side. According to this configuration, it is possible to make it difficult for the diaper to be displaced by putting on and off the pants after folding and rolling. As a configuration in which the static friction coefficient is smaller on the skin surface side of the 1 st region and/or the 2 nd region than on the non-skin surface side, a configuration in which the above-described 3D embossing is applied to the top sheet 14 on the skin surface side of the 1 st region and/or the 2 nd region to reduce the contact area with pants, a configuration in which a lubricant is added only to the skin surface side of the 1 st region and/or the 2 nd region, and a configuration in which the kind of lubricant is changed between the non-skin surface side and the skin surface side of the 1 st region and/or the 2 nd region can be employed.

< others >

The present invention is not limited to the above-described embodiments and the modifications described in any place, and can be appropriately modified and modified without departing from the scope of the technical idea of the present invention.

For example, the structure of the diaper according to the above embodiment or its modified example is not limited to the above-described open type, and any structure may be used as long as it is an absorbent article defined in claims. For example, pants-type disposable diapers, diaper pads, and the like can be applied to the present invention.

In the case where the absorbent article of the present invention is a pants-type disposable diaper, a sheet-like stretchable member having a thickness to form waist gathers may be provided over the entire circumference of the waist opening, a 2 nd thin region may be provided between a longitudinal end portion on the front body side of the diaper and a longitudinal end portion on the front body side of the stretchable member, a 3 rd thin region may be provided between a longitudinal end portion on the back body side of the diaper and a longitudinal end portion on the back body side of the stretchable member, and the length in the longitudinal direction of the 2 nd thin region and the length in the longitudinal direction of the 3 rd thin region may be made different. According to this configuration, the user can recognize the difference between the 2 lengths by the tactile sense, and therefore, the front and rear of the diaper can be easily distinguished.

In the case where the absorbent article of the present invention is a pants-type disposable diaper, the polyurethane sheet-like stretchable member forming the waist gather may be provided over the entire circumference of the waist opening, and thin regions having a thickness smaller than the thickness of the stretchable member and the thickness of the absorbent body may be provided in 2 regions between the crotch-side end of the stretchable member and the longitudinal ends of the absorbent body. Further, a thin region between a crotch side end portion on the back side of the stretchable member and a longitudinal direction end portion on the back side of the absorbent body may be set as a 1 st thin region, and a thin region between a crotch side end portion on the abdomen side of the stretchable member and a longitudinal direction end portion on the front side of the absorbent body may be set as a 4 th thin region, so that the length in the longitudinal direction of the 1 st thin region is different from the length in the longitudinal direction of the 4 th thin region. According to this configuration, the user can recognize the difference between the 2 lengths by tactile sensation, and for example, the difference in the length can be recognized by pinching the 1 st thin-wall region and the 4 th thin-wall region with the thumb and the index finger, so that the diaper can be easily divided into the front and rear. In addition, it may be: the 2 nd thin region is provided between the longitudinal end portion on the front body side of the diaper and the longitudinal end portion on the front body side of the stretchable member, and the 3 rd thin region is provided between the longitudinal end portion on the back body side of the diaper and the longitudinal end portion on the back body side of the stretchable member, and the length in the longitudinal direction of the 2 nd thin region is different from the length in the longitudinal direction of the 3 rd thin region. According to this configuration, the user can recognize the difference between the 2 lengths by the tactile sense, and therefore, the front and rear of the diaper can be easily distinguished.

In addition, the above-described embodiment or its modified examples are not limited to diapers for infants, but may be applied to various absorbent articles such as diapers for adults and diaper pads.

Further, the above embodiment or its modified example includes the configuration colored in the fastening band 10A and the configuration colored in the extensible member 10D, but in the present invention, it is also acceptable to include a configuration colored in either one of the both configurations or a configuration including neither of the both configurations.

Further, although the diaper 10 according to the embodiment or the modification thereof is provided with the 1 st thin-walled region T1, the 2 nd thin-walled region T2, and the 3 rd thin-walled region T3, respectively, it is permissible to provide no 2 nd thin-walled region T2 and no 3 rd thin-walled region T3 in the absorbent article of the present invention.

The above embodiments and modifications may be combined.
