Description

TRAINER SHEET DISPOSABLE. ENTALLADO. ADJUSTABLE. OR GARMENT FOR INCONTINENCE THAT HAS MEANS DISPOSABLE BACKGROUND AND FIELD OF THE INVENTION The present invention relates to a disposable trainer or incontinence garment where improved embossing and adjustability is provided. Specifically, the present invention relates to disposable trainers for a child or articles for incontinent adults. In general, these incontinent articles or training pants have elastic side panels, with layers of woven or non-woven fibers provided on the outer and / or inner faces of the elastic side panels. Conventional baby diapers and some incontinent adult products are produced with adjustable, adhesive closure systems provided on ears or handles or opposite corner portions of the garment. These closure systems comprise a small pressure-sensitive adhesive fastening strip permanently attached to a garment lug at one end of the small fastening strip with a free end of the small fastening strip stored on it. a release tape or film before use. The small fastening strip is permanently attached to one end of the diaper and the free end of the small fastening strip is releasably secured to an opposite end of the diaper when in use. The opposite end of the REF: 23640 diaper, generally the front end, is often provided with a reinforcing strip or tape on the inner or outer face of an outer liquid-impervious sheet, where the free end of the sheet is adhered. small fastening strip. The backsheet is conventionally a thin polymer or copolymer film. As the free end of the small, adhesive fastening strip can be placed across the entire front end of the diaper, the diaper waist opening easily adjusts to the individual user. When the child is trained to use the toilet or toilet, traditionally, a trainer pants is used. This trainer overall is a cotton garment provided with an absorbent fabric and is used in combination with an outer rubber pant, or the like. Recently, disposable trainers have become popular. However, these disposable coveralls lack the adjustability of a conventional fastening strip fastening system, adhesive of a conventional diaper. A slight adjustability in the entallamiento or sizing has been obtained by the extensive use of elastics in calzones disposable trainers. The elastics are used, for example; in the regions of the legs; in the waist regions; along the portions of the side panels of the training pants, as described in U.S. Patent No. 4,938,753 (Van Gompel * et al.)-stretchable side panels, with elastic; U.S. Patent No. 5,246,433 (Hasse et al.) - ear flaps with elastic; European Patent No. 547 497 A2 (van Gompel et al.) - elastic side panels having gradient stretch or elastic bands on the side panels; U.S. Patent 5,047,854 (Davis) - openings in the waist and legs with elastic; European Patent No. 526, 868 A2-Elastic front ear portions or US Patent No. 5, 163,932 (Nomura et al.) - waist and leg regions with elastic. Other patents that describe the use of elastics include U.S. Patent Nos. 4,940,464; 4,938,757; 5,171, 439; and 5,188,627. The difficulty with these designs rests on the limited adjustability provided by the elastics without considering the placement (either at the waist, legs or side panel region or a combination thereof) or the degree to which the elastic is used in the training pants. . Although in general the most used elastic, the most adjustable there are limits in the entallamiento or sizing. In general, the improvements in the fit of the trim decrease with the increased use of elastics in a trainer design. In addition, the use of increased levels of elastic in a disposable training pants also increases the complexity and cost of manufacturing. The present invention seeks to provide a disposable trainer brief with increased adjustability in the carving or sizing in addition to that which can be obtained with the elastics.

BRIEF DESCRIPTION OF THE INVENTION According to the present invention, a disposable trainer brief is provided having a fibrous outer fabric that can be coupled with the mechanical, male fasteners on a small mechanical fastening strip. The small mechanical fastening strip is located on a binding or sewing potion or the side panel of the training pant so that a free end of the small mechanical fastening strip is capable of engaging the outer woven or non-woven cover fabric. The free end of the small mechanical fastening strip adjusts the circumference of the trainer brief or the waist size or dimensioning by joining the side panel portion. The portion of the side panel is attached at least in part to be free of any integrally bonded absorbent core structure. Preferably, the permanent attached end of the small mechanical fastening strip is heat sealed to a fibrous outer fabric, or an upper sheet permeable to the liquid, inner or other fibrous fabric. This heat sealing permanently joins or closes at least some of the mechanical, male fastening elements of the small mechanical fastening strip to the fibers of the outer fabric, top sheet or other fabric. In a further preferred embodiment the free end of the small mechanical fastening strip may also be subsequently used as a disposable medium when the trainer pant is removed from the wearer, for example, by separating the side panel. The small clamping strip remains on the side panel portion of the trainer brief. The trainer shorts are then rolled up in a compact form to be discarded and the small mechanical restraint strip is used to keep the trainer's pants in a rolled up shape.

DESCRIPTION OF THE PREFERRED MODALITIES The constructions of the small mechanical fastening strip of the present invention will be described with reference to the disposable trainer brief, however, the constructions would be equally applicable to other similar disposable garments and incontinent devices. A disposable underpants are shown, known in Figures 1 and 2, wherein the underpants frame or chassis (1) is formed of an absorbent core (2) containing a portion and portions of the side panels (10) designed to carve around the user's hip. The portions of the side panels (10) with the absorbent core define the openings of the legs in the chassis or frame of the trainer shorts. The structure of the absorbent core (2) would be of conventional design, as described, for example, in U.S. Patent No. 5,246,433, using fibers and / or absorbent particles in the form of a discrete pad. The pad is covered on one inner side by a liquid-permeable upper sheet (11) and on the outer side by an outer layer impervious to liquid (18): The liquid-permeable top sheet (11) can cover the absorbent core (2). ) and extend continuously within the portions of the side panels (10), as shown in Figure 2, or can be attached to the portions of the side panels (10) by a seam (not shown). Similarly, the liquid impermeable outer layer (18) can extend beyond the portion of the absorbent core (2) within the portions of the side panels (10), as shown in Figure 2, or it can be joining by a seam (6) to a portion of the side panel, described (10). In a preferred arrangement, as shown in Figure 2, the liquid impervious outer layer (18) is a sheet material comprising an inner layer impervious to liquid (17) laminated to an outer layer (19) of a fibrous web. The inner layer (17) would preferably be a liquid-impermeable plastic film, such as a polyethylene or polypropylene film or a consolidated woven or non-woven fabric. The outer layer (19) is preferably a soft woven fabric (including interwoven or knitted fabrics) or nonwoven, such as spun, spunbonded, carded or otherwise formed nonwoven fabric formed from synthetic and / or natural fibers. Preferably, the fibrous fabric (19) is sufficiently consistent and high, such that the fibers of the fabric (19) are spaced far enough apart from each other and the backs, such that the fibers are coupled with the mechanical fastening elements, male of the free end of the small mechanical fastening strip. The upper liquid permeable sheet (11) is of conventional design as used in disposable diapers and would generally be a linked spinning fabric of hydrophobic thermoplastic fibers (ie, polypropylene fibers). The layers of the backsheet and the backsheet 11 and 18 are joined to each other and the absorbent pad by conventional lamination techniques, which include the use of hot melt adhesives, thermal bonds, sonic joints and the like. The portions of the side panels (10) may be integral with the front panel (31) of the absorbent core portion (2) and / or the rear panel portion (32) of the absorbent core portion (2) or be they are joined together by a side seam (5), as shown in Figure 2. Alternatively, the side panels (10) can be integral with either the front panel (31) or only the rear panel ( 32) and extend to the opposite rear or front panel and are joined to the opposite panel by adhesion, casting, or the like, as described in the PCT. 94/00292, published January 6, 1994. In an alternative embodiment shown in Figure 1, the side panels 10 are joined at the seams or seams (6) to both the front panel 31 and the rear panel (32) with an intermediate seam or union (5). The intermediate seam (5) in this arrangement could be eliminated by the use of a single side panel element, however, preferably the intermediate seam (5) is used to facilitate the manufacture of the trainer pants, as described in U.S. Patent Nos. 4,938,757 or 5,246,433 and the incorporation of the small mechanical fastening strip (20) in the joint or seam (5). The side panels (10) can be elastic or non-elastic, however they are preferably elastic, such as by incorporating an elastomeric layer (15) to facilitate the embossing. The elastomeric layer (15) can be any conventional elastomeric woven or nonwoven fabric comprising elastomeric fibers such as meltblown fibers, spun bonded fibers, extruded fibers, or the like or a co-extruded elastomeric film. At least the outer or inner side of the side panels (10) are provided with a woven or non-woven fibrous fabric, (12) or (14), they are coupled with the mechanical fastening elements, male (25) on the small strip mechanical fastening (20). The small mechanical fastening strip (20) has an array of male, straight, or upright mechanical fastening elements (25) which may be in the form of straight or upright spikes having structures that engage the fibers at the distal end , structures that are coupled to the fibers which have a suitable shape for coupling to the fibers. Preferably, the male, mechanical fastening elements would be in the form of straight or upright hook or fungal structures. The elements (25) in general are 75 to 500 microns high from the base of the spike to the outer tip of the structures that are attached to the fibers. The spikes, different from the structure that is attached to the fibers, distal end, in general would be free of structures that are attached to the fibers or prominences and would be straight or tapering inward from the base of the spike to the structure that is Fits the fibers, from the distal end. The structures that engage the fibers of the distal end would generally extend outward, preferably outwardly and downwardly, of the spike at a distance of at least once the average fiber width coupled. At an industrial end (22), the small mechanical fastening strip (20) is permanently bonded to the extension of the upper, inner sheet (11), the inner fibrous fabric (12) or the outer fibrous fabric (14). The male mechanical fastening elements (25) at the opposite free end (21) remain free to releasably couple an outer fibrous web (14), layer of the outer fibrous web (19) or a discrete mechanical fastening element. attached to a side panel (10) or to the front panel (31). This mechanical fastening element will also be a fibrous fabric, such as a woven fabric (including interwoven or knitted fabric) or nonwoven where the fibers are sufficiently consistent and high (for example fibrous meshes or an open fiber structure) for coupling the mechanical fastening elements, male. The mechanical coupling fastener element can be extended through the entire side panel and / or the front panel or back panel or only a portion of the side panel or front panel or back panel, or a combination thereof. The permanent link at the fabricated link end or the manufacturer 22 is preferably formed by the male, mechanical fastening elements (25) that securely attach the fibers of the topsheet or a fibrous web (12, 14, 19). or a coupling mechanical fastening element). This secure coupling is created preferentially by closing the mechanical fasteners around and between the fibers of the upper sheet or fibrous fabric, using heat melt, pressure cast, ultrasonic melt, mechanical cast or the like, however, an adhesive may also be employed. In this way, certain of the mechanical fastening elements (25) permanently fasten the small fastening strip (20) to at least one panel while other mechanical fastening elements (25) on the free end (21) of the The small retaining strip (20) remains undeformed to releasably couple the fibers of an outer fibrous web (14 or 19) or a properly stored mechanical clamping element.

The small mechanical fastening strip (20) allows for extensive adjustments to the fit or sizing of the trainer pant (1) by joining the excess side panel material between the permanently attached drawn end (22) and the user's free placed end (21) . The embossing can also be adjusted after use to join the excess material created due to the elastic hysteresis or cold stretching of the side panels (10) or the structure of the absorbent core (2) of the chassis or frame of the trainer (1) ). Either one or more small mechanical fastening strips (20) can be placed on or adjacent to each side panel (10), with small mechanical fastening strips (20) movable on one or both sides of the trainer pant (1). When the trainer pant (1) is ready to be discarded, the small mechanical fastening strip (20) can be used to keep the trainer pant in a rolled or folded form, as shown in Figure 6, by properly fitting the end. free (21) of the small mechanical fastening strip (20) where the processed end (22) remains permanently attached to the panel (10). Figure 3 shows a preferred embodiment for placing the small fastening strip (20) between the adjacent side panels (10) connected by a seam (5), as shown in Figure 1. Although in the Figure 1 this joint or seam (5) is shown provided equidistantly between the front and rear panels (31) and (32) of the structure of the absorbent pad (2), the joint or seam (5) can be placed in any location and one or more seams or seams may be provided depending on the number and type of side panels (10). For example, in European Patent Application No. 320 989, a non-elastic, broken side panel is provided, intermediate between the two elastic side panels providing at least two seams or seams and three side panels intermediate to the front and rear panels ( 31) and (32) of the structure of the absorbent core (2). The side panels (10) are joined along the joint or seam (5) by the use of heat, pressure, ultrasound or the like, which preferably permanently couples the mechanical, male fastening elements simultaneously (25). ) at the processed ends (22) with the fibers of the inner fibrous fabric (12) or an extension of the upper sheet. If the side seam (5) is subsequently torn in order to remove the trainer shorts, the small mechanical fastening strip (20) will remain permanently attached to a panel member (10) by the fasteners (25) in the frame. elaborated end (22), being properly released from the opposite panel element (10) on the opposite side of the small strip along the side seam (5). In the alternative embodiment of Figure 4, the small mechanical fastening strip (20) is permanently attached to the outer fibrous web (14) in a side panel (10). Alternatively, the outer fibrous web could be a cloth 19 or a mechanical fastening element, coupling. Preferably, the permanent joint is formed simultaneously with the formation of the side seam (5), however, this permanent joint can be created before or after the formation of the side seam (5). The mechanical joining of the fastening elements (25) at the end of the manufacturer (22) with the fibers of the fabric (14) keeps the small fastening strip (20) temporarily in place before the formation of the permanent joint through the application of heat, pressure, ultrasound or the like, to permanently join at least some of the fastening elements (25) with the fibers of the fabric (14). In the embodiment shown in Figure 5, the small mechanical fastening strip (20) is attached at the processed ends (22) to one side of the side panel (10) having an outer fibrous web (14). Figure (5) shows the presence of a fused side joint or seam (29), which can be formed in the manner described in U.S. Patent No. 5,246,433. As is clear from the foregoing description, the design of the trainer pant of the invention allows for extensive adjustments in the notching and sizing, by a suitable joining of the side panel material between an elaborate end (22) permanently attached and a free end ( 21) of a small mechanical fastening strip (20). The permanent joint at the end (22) can be created without the need for adhesive, although in itself it could undoubtedly be employed, and is easily integrated into known manufacturing schemes employing heat, ultrasound or pressure to form lateral seams or seams for the joints. disposable trainers shorts. The various modifications and alterations of this invention will be apparent to those skilled in the art without departing from the scope and spirit of the invention, and this invention should not be restricted to that set forth for purposes of illustration only.

It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it relates.
