Description

DISPOSABLE GARMENT THAT HAS A HANDLING OF OPENING BY IMPROVED RASGADURA AFTER MESSAGE FIELD OF THE INVENTION _ The present invention relates to disposable garments that carve. Examples of these pre-cut garments include disposable undergarments, fitted nappies, training pants, and disposable panties for menstrual use. The present invention relates more particularly to a unitary disposable absorbent garment such as fitted nappies, training pants, trusses that fit for adult incontinence, and the like, which provide improved aperture handling by tearing after staining. .

BACKGROUND OF THE INVENTION Babies and other incontinent individuals use disposable absorbent articles such as diapers to receive and contain urine and other exudates from the body. Absorbent garments that have fixed sides (for example, training pants or fitted nappies) have become very popular for use in children who are able to walk and are often taught to go to the bathroom. In order to contain body exudates, as well as adjust to a wide variety of body sizes and shapes, these pants must be tightly wrapped around the wearer's waist and legs, without falling, collapsing or sliding downward from their position , on the torso, as well as adjusting to larger users without causing irritation to the skin because the product is too narrow. In this way, the pants must have sufficient elastic extension capacity at the waist and legs with the elastic characteristics that a degree of elasticity provides.

Elevated Stretch Many training pants and fitted nappies use conventional elastic elements secured in an elastically contractible condition at the waist and leg openings Typically, for the purpose of securing the fit and fully elastic around the legs and waist as provided with durable undergarments, the leg openings and the waist opening are surrounded by elastic rubber bands or other matting placed along the opening curve. These briefs are typically characterized as "balloon style" shorts, because of ' shrinkage caused by elasticized bands and specific areas of the product, while the remaining matepal tends to fall into folds. Examples of these training pants are disclosed in U.S. Patent No. 5,171, 239 by Igaue, and others on 15 December 199, and in the United States Patent No, 610,681 per Strohbeen et al. On September 9, 1986. These training pants typically have side panels, the edges of which are sewn together to form two leg openings and a waist opening. In a typical manner of forming seams, the sides facing the body of the sewing panels are sewn together on their edges Examples of this way of sewing or joining are disclosed in the antecedently referenced patents of the United States No 5, 171, 239 and 4 610,681 In another typical way of sewing or joining, the side that one toward the body of a seam panel and the side facing away from the other seam panel are stitched together into their opponents. An example of such a way of joining is disclosed in U.S. Patent No. 5,569.23 by Buell and others on October 29, 1996 The last way to join generally provides a stitching structure stronger than the previous way of joining In particular, to ensure a better fit of garments from pitches that are put on, the seams are required to withstand great forces during application and use. Otherwise, these forces and stresses may cause the side panels to separate or tear open. Although those stronger stitching structures are highly desirable, it is also desired that in addition, the joined or sewn panels can be easily torn open by the user's fingers after staining. However, because of the strength of the seam. The overlapping seam structure tends to be difficult to open by tearing after the notch garment has been soiled. Based on the above, there is a need for a disposable garment that has notched side seams that are strong enough to withstand the large forces during application and use, while not interfering excessively, with the removal of the garment afterwards. to mess. None of the existing art provides all the advantages and benefits of the present invention.

Figure 1 shows a perspective view of the disposable diaper notching 10 according to the aspect of the present invention. The notching diaper 10 has an external surface, an inner surface, a front portion 11, a rear portion 12, a crotch portion 13, each of the front portion 11 of the back portion 12 having side panels with side edges 1, overlapping side seams 15, which join together to the side panels of the front portion 11, and to the rear portion 12 to form the leg openings 16 and a waist area, and at least one side flap 17 (or tear opening tab) that is disposed outwardly from each side of the shore! 1 of the side panels forming the outermost portions of the overlapping side seams 15 Preferably, the side flap 17 is an integral part of the disposable diaper that is notched The notch diaper 10 preferably comprises a chassis layer, an elastically extensible stretch laminate placed in each side panel of the front portion 11, laminate of front stretches, an elastically extensible stretch laminate, placed on each side panel of the post-up portion 12, post-stretch laminates, and at least one elasticized waistband positioned on both sides of the front portion 11 and the post portion 12 The notch diaper 10 comprises leg openings 16, which additionally comprise elastic leg features to improve leg adjustment in the crotch portion 13 The notch diaper 10 can be supplied with openings or vents (not shown), in at least the side panels of the diaper that notches 10 to provide breathability and ventilation The notch diaper 10 has a crotch portion 13, which comprises a main panel and a pair of leg flap panels. The absorbent core is generally positioned within the main panel of the crotch portion 13, since the body exudates are typically incorporated in this area A leg flap panel extends generally laterally outwards from and along each lateral edge of the main panel Each leg flap panel generally forms at least a portion of the elastic leg feature The outer surface of the notch diaper 10 comprises that part which is placed away from the body of the user during use The inner surface of the honeycomb 10 it is opposite to the external surface and comprises that part of the diaper which is placed adjacent to the body of the user during use. The stretch laminates elastically extensible (front stretch laminates and rear stretch laminates) are formed in each side panel of both of the front portion 11 of the postepor portion 12 Each stretch laminate is stretched or mechanically lengthened to allow the stretch laminate to be elastically extensible in at least the lateral direction (lateral direction or x or width direction), is defined as the direction Parallel to the lateral centerline of the diaper that cuts 10) The bread The laterals are preferably an extension of a chassis layer and other elements such as the topsheet, or any other combination of these elements. In the overlapping side seams 15, the stretch laminate is preferably activated by mechanical stretching to provide extensibility in This region The overlapping side seams 15 may also not be activated by mechanical stretching In order to provide the necessary absorbency to contain the bodily discharges, the notching diaper 10 comprises a liquid permeable top sheet and an absorbent core placed between the top sheet and the chassis layer The top sheet is placed adjacent to the body surface of the absorbent core and is preferably the absorbent core and the chassis layer by attachment means such as those well known in the art. In a preferred embodiment the top sheet and the chassis layer are very direct They are joined together by attaching them directly to the absorbent core or to the elastic panel members or other elements of the notch diaper The top sheet preferably it comprises three distinct layers joined together. A liquid-permeable primary layer is placed on the absorbent core to rapidly absorb liquids into the product. The barrier layers are bonded to the primary layer and are preferably elongatable, more preferably hydrophobic, to allow the side panels to remain mechanically stretched without tearing apart while providing barrier folds along the sides of the notch diaper 10. The elastic leg features preferably comprise a packing fold and a barrier fold. The packing fold is preferably formed by one or more elastic leg members operatively attached to the chassis layer, the barrier layer or amboe, preferably between the barrier layer and the fin portion of the barrier layer. in the leg flap panel of the crotch portion 3. The barrier fold is preferably formed by a flap (the erect portion of the barrier layer), the closure members to secure the longitudinal ends of the erect portion to the flap. primary layer, and an elastic separation member operatively linked to the erect portion.The primary layer is preferably docile, soft-feeling, and non-irritating to the user's skin, the primary layer is permeable to liquid (eg, urine, penetrate easily through thickness.) A suitable primary layer can be manufactured from a wide range of materials, such as porous foams, cross-linked foams.; plastic films with openings or films formed three-dimensionally expanded; woven or non-woven wefts of natural fibers, synthetic fibers, or a combination of natural and synthetic fibers. Preferably, the primary layer is manufactured by Amoco. The primary layer is preferably non-coextensive with the chassis layer such that liquids will not impregnate along and through the primary layer towards the edges of the notching diaper 10, such that liquids will not impregnate below and below. beyond the erect barrier folds formed by the barrier layers, and in such a way that the More stretchable materials can be placed on the side panels to produce stronger stretch laminates. The primary layer preferably covers a larger part of the body surface of the absorbent core, more preferably all of the body surface area of the absorbent core in at least the crotch portion 13 such that the exudates that are discharged into the diaper They carve 10 penetrate through the primary layer where they are absorbed by the absorbent core. The primary layer extends laterally outwardly towards the lateral edges of the absorbent core, preferably beyond the lateral edges of the absorbent core in at least crotch portion 13. However, the primary layer ends inward from the leg edges. of the crotch portion 13. In the most preferred configurations, the primary layer ends adjacent to the proximal edge of the barrier layer, (ie the terminal edge of the primary layer is positioned adjacent to the proximal edge), or the edge terminal is placed away from and inward from the adjacent, "adjacent" shore, is used in this context to imply that the primary layer ends in the near shore more or less the small areas of the primary layer material that can extend inward or beyond the near shore due to machine tolerances during manufacture or variations in the area of the primary layer when it is manufactured. In the top sheet embodiment, the barrier layers form the characteristics of an elastic leg (preferably, a gusset fold and / or a barrier fold), and, preferably, a portion of the stretch laminates. The chassis layer preferably comprises a continuous sheet or web, which defines the front portion 11, the back portion 12, and the crotch portion 13. In this manner, the chassis layer is the primary layer or extract of the diaper that notch 10. (as used herein the term "layer" does not necessarily limit the element to a single extract of material in which a layer may actually comprise laminates or combinations of sheets or frames of the type of materials required). The chassis layer has an internal surface and an external surface. The internal surface, and the outer surface of the chassis layer corresponds in its orientations to the inner surface and the outer surface of the notching diaper 10. In preferred embodiments, the chassis layer generally determines the overall shape of the notched diaper. 10. The chassis layer acts as the main structural layer of the notching diaper 10 to which other features can be added or joined. The chassis layer is thus placed in all or most of the surface area of the notch diaper 10, although in certain embodiments, certain parts of the chassis layer can be perforated, cut out or removed ("with window"). , or increase the stretch capacity and / or breathability of the notch diaper 10 or the characteristics of the diaper notch 10 in that area. The chassis layer can thus comprise a continuous sheet or web having no "seams" or "seams", such that the forces are transmitted in a distributed manner throughout the entire layer or the chassis layer can comprise a sheet or continuous pattern "that do not have unions", with elastified leg folds 12. As discussed hereinabove, the continuous sheet or web of the chassis layer may comprise a simple web of material or a laminate of several continuous webs or layers of different materials. The chassis layer can form the outer surface, the inner surface, or part of either or both, or it can be completely placed inside the notching diaper 10. The chassis layer preferably forms an outer surface of the diaper notching 10 the crotch portion 13. Since at least a portion of the chassis layer is subject to mechanical stretching, for the purpose of providing stretch laminates on the side panels, it is preferably stretchable, more preferably stretchable (but not necessarily elastomeric) , so that the chassis layer will be, when stretched mechanically at least to a permanently elongated degree, such that it will not fully return to its original, undistorted configuration. The chassis layer can thus comprise any of the known materials for use in the absorbent articles such as non-woven or woven wefts; polymeric films, such as polyethylene thermoplastic films, polypropylene, or mixtures thereof, laminates of these materials; or composite materials. In preferred embodiments, the chassis layer can be mechanically stretched with minimal or no tearing or ripping. Therefore, the chassis layer is preferably a polymeric film. Due to the fact that the chassis layer is preferably a polymeric film, it is also generally impervious to liquids (eg, urine), so that it can also serve as the component that prevents the general discharges absorbed and contained within the absorbent core, moisten garments that are in contact with the diaper that adjusts 10, such as sheets and undergarments, ie, this acts like the backsheet of the traditional diaper). If the chassis layer is not impervious to liquid, typically an additional layer such as a traditional backsheet should be used behind the absorbent core. The chassis layer can also be breathable (permeable to air or water vapor), if desired. The chassis layer may alternatively comprise breathable materials that are microporous and that are typically inferior to stretch and elongation. An example of this film is that manufactured by Exxon Chemical Company under the trade name EXXAIRE. Exemplary films to be used as the chassis layer having relatively good stretchability but which are not breathable, include polymer films manufactured by Clopay Coforation of Cincinnati, Ohio, under the designation Clopay 1401, or available from Tredegar films of Terre Haute, Indiana, under the designation X-8323 or X-9954. The size of the chassis layer is dictated by the size of the user or diaper notch 10 that is designed to fit. In a preferred embodiment, the chassis layer has a modified hourglass configuration to better fit the user. In a mode designed to fit larger babies (from about 9 kilograms to about 15.4 kilograms), the chassis layer is preferably approximately 483 mm long by approximately 234 mm wide in the frontal region and in the posterior region, and approximately 165 mm wide in the crotch region. The side panels are approximately 41 mm wide, the activated portion of the side panels is 32 mm wide, and the lap seams 15 are approximately 8.5 mm wide (the actual overlap area of the lap seams 15 is approximately 11 mm in the modality shown there). The front portion 11 is approximately 114 mm long, the rear portion 12 is approximately 165 mm long, and the crotch portion 13 is approximately 220 mm long.

The seams are formed by joining the side panels of the front portion 11 together to the side panels of the back portion 12. The seams can be joined by any suitable means well known in the art, appropriate for the specific materials used in the seams. sewing panels. In this way, sonic sealing, heat sealing, pressure bonding, adhesive bonding, sewing, autogenous bonding, and the like may be the appropriate techniques. In a preferred embodiment, the side panels of the front portion 11 and the side panels of the back portion 12 join to form the overlapping side seams 15. The overlapping side seams 15 are joined by a pattern of heat welds / pressure or ultrasonic. In this particular embodiment, the seams comprise a pattern of intermittent individual joints grouped in a cluster. The potentially strong overlapping side seams can be produced by increasing certain amounts of polymeric material in the side seam panels 15. The amount of polymeric material in the side seams 15 can be increased by using higher-weight non-woven materials, thicker plastic films or by introducing layers of additional mats to the side panels. For example, additional plastic films or non-woven wefts can be joined in the side panels. Alternatively, the layers which form the notching diaper 10, can be extended beyond the intended area of the seam and folded back into the side panel to introduce additional layers into the side panels Examples of these types of stitching are discussed in the foregoing referenced patent of the United States No. 5,236,430 The notch diaper 10 comprises ury leg area 14 comprising elastic leg cuffs 12 to provide improved fluid containment and other exudates from the leg Elastic leg characteristics provide improved containment of liquids and other exudates of the spine in the crotch portion 13, and around the leg openings 16 in general. Each elastic leg feature can comprise various different modalities to reduce the drainage of body exudates in the leg flap panels. The elastic leg feature can be and is sometimes also referred to as bands. of leg, side flaps, barrier folds or elastic folds) U.S. Patent No. 3,860,003 discloses a disposable diaper that provides a collapsible leg opening 16 having a side flap and one or more elastic panel members to provide a fold Elastic Leg (Packing Fold) United States Patent No 4,909,803 discloses a disposable diaper having "upright" elasticated fins (barrier folds), to improve containment of leg regions. U.S. Patent No. 4,695,278 teaches a disposable diaper having double folds that include a gusset fold and a barrier fold. U.S. Patent No. 4,795,454 discloses a disposable diaper having double folds resistant to Runoffs where the top sheet for near the side edge of the diaper to prevent impregnation outside the side of the garment. Although each elastic leg feature can be configured to be similar to any of the leg bands, side flaps, barrier folds or elastic folds described above, it is preferred that each elastic leg feature comprises a combination of a gusset fold and an elastic leg feature. barrier fold. The packing gusset and the barrier folds are preferably formed as shown in U.S. Patent No. 4,795,454. The absorbent core is preferably positioned adjacent to the inner surface of the chassis layer and is preferably attached thereto by joining means such as those well known in the art. For example, the chassis layer can be secured to the absorbent core by a continuous uniform adhesive layer, a patterned adhesive layer, or an array of separate lines, coils, or adhesive spots. Alternatively, the joining means may comprise heat bonds, pressure joints, ultrasonic joints, mechanical dynamic joints, or any other suitable joining means or combinations of these joining means as are known in the art. The absorbent core can be any absorbent means that is generally compressible, conformable, non-irritating to the wearer's skin, and capable of absorbing and retaining liquids such as urine and other certain coforal discharges. The absorbent core can be manufactured in a variety of sizes and shapes (eg rectangular, hourglass, "T", asymmetric, etc.), and from a wide variety of absorbent materials commonly used in diapers disposable and other absorbent articles such as crushed wood pulp, which is generally referred to as an air filter. Examples of other suitable absorbent materials include accreted cellulose wadding, meltblown polymers, including coform, crosslinked cellulose fibers, tissue, including tissue wraps, absorbent foams, superabsorbent polymers, absorbent gelling materials or any equivalent materials or combinations of materials. The configuration and construction of the absorbent core can also be varied (for example, the absorbent core can have zones of variable gauge, hydrophilic gradients, superabsorbent gradients, or acquisition zones of lower basis weight and lower average density, or they can comprise one or more layers or structures).

However, the total absorbent capacity of the absorbent core must be compatible with the design load and with the intended use of the notch diaper 10. In addition, the size and absorbent capacity of the absorbent core can be varied to encompass users ranging from babies to adults. A preferred embodiment of an absorbent core has an asymmetric modified hourglass shape and has a body surface toward the user's body (inner surface), of a garment surface opposite the body surface. An exemplary absorbent structure for use as the absorbent core which has achieved wide acceptance and commercial success is described in U.S. Patent No. 5,360,420. Preferably, the absorbent core will comprise an acquisition / distribution layer of chemically hardened cellulosic fibers and a storage layer positioned below the acquisition / distribution layer, comprising a mixture of wood pulp fibers and superabsorbent material as disclosed in U.S. Patent No. 4,610,478. The notch diaper 10 may also preferably be provided with vents or openings to allow passage of air and water vapor to and from the interior of the notch diaper 10. In a preferred embodiment, the openings are placed in the side panels. In this configuration it is avoided that the corporal discharges run out of the areas adjacent to the absorbent core but it allows the air and water vapor to be exchanged in the product, to ventilate it in such a way that the product does not get to get wet excessively through body perspiration and being uncomfortable to use. Ventilation holes may additionally be provided in other panels of the notch diaper 10 or over certain features of the notch diaper 10, such as in the waistband. The notching diaper 10 would preferably have a plurality of ventilation holes within the side panels, the ventilation holes being arranged in a defined pattern of large and small openings. The breathability can be provided alternately by making the diaper materials that mesh 10 of air permeable or vapor permeable materials as is known in the art. For example, the chassis layer may comprise a breathable plastic film (vapor permeable). The elastic panel members may be of open material, such as foams, non-woven material canvases, or breathable elastomeric films to further increase the breathability of the notch diaper 10. In a particularly preferred embodiment, the breathable waistband to allow vapor to escape of water of the frotal portion 11 and of the back portion 12, of the notch diaper 10. Breathability can be provided in the waistband by selecting relatively breathable materials for its construction and / or for perforating or forming ventilation holes in the waistband such as discussed here with respect to the stretch laminates on the side panels. In another embodiment, the waistband may be hydrophobic, hydrophilic, or a combination of hydrophobic / hydrophilic member, a hydrophilic waistband may be used to pull moisture away from the wearer's skin, to prevent the skin from becoming hydrated. Alternatively, a hydrophobic waistband can be used to prevent fluid absorbed by the diaper 10 from leaking out through the waist openings. A hydrophobic / hydrophilic waistband combination can be used to prevent fluid absorbed by the diaper 10 from leaking out through the waist opening, while also removing moisture from the user's skin, to prevent the skin from hydrating. . The present invention also relates to a method for making a slotted disposable diaper 10. Referring to Figure 11, before joining the side panels of the front portion 11 to the side panels of the back portion 12, the side flap or tear opening tab 17 is cut from the side edges 14 of the side panels that eventually form the outermost portions of the overlapping side seams 15. For this embodiment, the tear-open tab 17 is cut from the side edge 14 of the side panel of the back portion 12, is say, the tear opening tab 17 is disposed outwardly from the lateral edges 14 of the side panels. In an alternate embodiment, the side panels of the back portion 12 can be attached to the side panels of the front portion 11, and for this the tear tab 17 is cut, starting from the side edge of the side panel 11. The tab The tear-open opening 17 preferably has a curved shape for ease of handling and is preferably disposed along the side edge 14 of the side panel which corresponds to either the waist area, the leg area or the area between the skin area. waist and leg area. No extra material is needed to create the tear-open tab 17. In this manner, the tear-open tab 17 is an integral part of the notch diaper 10. An alternative to this integral structure is a tear-open tab 17. which can be attached to any edge 14 of the side panel of the front portion 11 or of the side edge 14 of the side panel of the portion 12 of the chassis prior to assembly, using means well known in the art. The notching diaper 10 can be applied by a caregiver or self-applied by the user. Typically, the waist opening will expand to allow the user to insert one of their feet into one of their leg openings 16. The other foot is then inserted into the other leg opening 16. The diaper notch 10 is then pulled towards up on the user's torso to its position of use. The wall of force created by the stretch laminates especially help in the self-application of the diaper that cuts forcing the diaper 10 that is pulled up on the buttocks instead of expanding more. The notch diaper 10 is then used and can contain and retain the discharged coforal exudates. The notch diaper 10 is removed from the wearer by tearing open the tear opening tab 17 disposed outwardly from the side edges forming the outermost portion of the lap side seams 15. Figure 1 is a perspective view of a disposable diaper notch 20 according to another aspect of the present invention. Referring to Figure 1, the notch diaper 20 comprises a chassis 41 having a front region 26, a back region 28 and a crotch region 30 between the front region 26 and the rear region 28. The chassis 41 comprises a sheet liquid-permeable upper 80, a liquid-impermeable backsheet 22, associated with the topsheet 80, and an absorbent core 84 (not shown in Figure 1), disposed between the topsheet 80 and the backsheet 22. The diaper that notch 20 further comprises front panels 46 each extending laterally outward from the corresponding side of the chassis 41 in the front region 26 and lateral rear panels 48 each extending laterally outward from the corresponding side of the chassis 41 in the rear region 28. diaper groove 20 further comprises seam panels 66, each extending laterally outwards from each of the front and rear side panels s 46 and 48; rip-opening tabs 31 each extending laterally outward from the seam panels 66. Preferred examples of the notch diaper 20 are disclosed in the patents of the United States.

In the embodiment shown, the elastic waist feature 50 preferably comprises a cover of belt / waistband unit 82 operably linked in the waistband panel in an elastically contractible condition, preferably to the primary layer of the top sheet 80. The waistband / unitary waistband 82 acts as a barrier to the drainage of exudates out of the opening waistband of the diaper 20, as well as a collapsible waistband to provide the fit of the notch diaper 20 around the wearer's waist. In the most preferred embodiments, the unit waist / waist cover is also breathable to allow venting of the water vapor out of the notch diaper adjacent the waist opening. In the embodiment shown in Figure 3, the notch diaper 20 is also provided with an elastic waist feature 52 to improve fit on the legs in the crotch region 30. The notch diaper 20 additionally comprises an upper sheet 80 and an undercut diaper. absorbent core 84 (not shown), positioned between top sheet 80 and chassis layer 40, to provide an absorbent assembly that cooperates with the web to contain discharged exudates. Figure 4 is a cross-sectional perspective view of the notch diaper 20 taken along line 4-4 of Figure 3, in the front region 26. The chassis layer 40 is shown to form the stratum or layer primary diaper 20 and has an inner surface 76 and an outer surface 77. The first web layer 42 is placed on the outer surface 77 of the chassis layer 40 to form the backsheet 22 of the diaper notch 20 in the front region 26.

Barrier layers 88 extend laterally outwardly from primary layer 86 towards side edges 72. Each barrier layer 88 nde a fin portion 90 and an upstanding portion 92. The upstanding portion 92 is not attached to the primary layer 86, to allow the gathering forces of the elastic separation members 94 to cause the upstanding portion 92 to lift away from the surface the primary layer 86 to form a barrier fold 93, which is a barrier or wall during use. The fin portion 90 extends laterally outwardly from the upstanding portion 92. (the proximal edge), towards the side edge 72. The absorbent core 84 is preferably positioned between the primary layer 86 and the chassis layer 40. The construction of the rear region 28 is preferably identical to the construction of the front region 26. Figure 5 is a partially cut-away plan view of the diaper showing 20 shown in Figure 1, in its apyled state, not contracted (i.e., with the contraction induced by the elastic, pulled out except for the side panels where the side panels are left in their relaxed condition), with the inner surface 24 of the notching diaper 20 facing towards the observer, before the front region 26 and the back region 28 are joined together by the seams. For the purpose of providing the absorbency necessary to contain the exudates of the body, the notch diaper 20 comprises a liquid-permeable Top sheet 80, and an absorbent core 84 positioned between the top sheet 80 and the chassis layer 40. In the modality shown in Figure 5, the topsheet 80 preferably comprises 3 distinct layers joined together. A liquid permeable primary layer 20 and 86 is placed on the absorbent core 84 to rapidly absorb liquids into the product. The barrier layers 88 are bonded to the primary layer 86 and are preferably stretchable, more preferably hydrophobic to allow the side panels to be mechanically stretched without tearing or tearing, while providing barrier folds 93 along the notch diaper 20. The barrier layers 88 have a flap portion 90 and a channel or upright portion 92 to provide the various components of the elastic leg features 52. The leg features elastic 52 preferably comprises a packing fold 91 and a barrier fold 93. A packing fold 91 is preferably formed by one or more elastic leg members 96, operatively attached to the chassis layer 40, the barrier layer 88, both , preferably between the chassis layer 40, and the fin portion 90 of the barrier layer 88 on the leg flap panel of the crotch region 30. The barrier fold 93 is preferably formed by a flap (the erect portion). 92 of the barrier layer 88), closure means 98 for securing the longitudinal ends of the upstanding portion 92 to the primary layer 86, and an elastic separation member 94 operatively attached to the upstanding portion 92. The capacity of Elastic extension in the side panels 46 and 48 can be provided by a number of different materials and configurations. The various components of the web (for example, the web layer or the chassis layer) can comprise conventional elastic materials or the side panels of the web can be constructed from a number of different elastic laminated structures. For example, the side panels of the web may comprise an elastic material operably linked to one or more inelastic components (the web layer or the chassis layer or both) in an elastically contractible condition as described in the United States No. 3,860,003 entitled "Shrinkable side portions for a disposable diaper", issued to Buell on January 14, 1975. Alternatively, the side panels may comprise a film frame in the form of structural elastic (SELF) such as is described in WO 95/03765, "Screen materials exhibiting performance in the form of elastic", The Procter & Gamble Company, published February 9, 1995. Although the side panels of the web can be constructed from a number of different stretchable or elastic materials as are known in the art, one or more, and preferably each, of the Side panels of the band are constructed from a laminate of stretching. In a preferred embodiment of the present invention, an elastic panel member 78 is operatively attached to the side panels 46 and 48, preferably between the chassis layer 40, and the band layers 42 and 44, to allow the side panels 46 and 48 are elastically extensible in at least the lateral direction. Elastomeric materials that have been found to be especially suitable for use as elastic panel members (especially for zero tension stretch laminates), are elastic films based on the styrene block copolymer, preferably having a thickness of 0.05 mm - 0,064 mm, as made by Clopay Corporation of Cincinnati, Ohio under the designation PA18-2870 or the elastic films of the Exxon 500 series from Exxon Chemical of Baytrown, Texas. Other elastomeric materials suitable for use as the elastic panel members, include "active" synthetic or natural rubber, or other synthetic or natural rubber foams, elastomeric films (including heat-shrinkable elastomeric films), woven or non-woven elastomeric fabrics, canvases, materials elastomeric compounds, or the like. More preferably, the elastic panel member 78 is an elastomeric canvas material. This elastomeric canvas material is provided with a plurality of first yarns intersecting a plurality of second yarns, forming an open network-like structure having a plurality of apertures. Each opening is defined by at least two first adjacent threads and at least two adjacent second threads, such that the openings are substantially rectangular in shape. A preferred elastomeric canvas is manufactured by Conwed Plastics Company under the designation TN2514. In a more preferred embodiment, the elastic panel members are operatively attached to the side panel by securing them to the chassis layer 40, the band layers 42 and 44, or both while in a substantially non-existent condition. stressed (zero voltage). At least a portion of the resulting composite stretch laminate containing the elastic panel member is then subjected to sufficient mechanical stretching to permanently elongate non-elastic components (the chassis layer, the barrier layer, and the band layer). ), of the stretch laminate. The composite stretch laminate is then left to return to its substantially unstressed condition. The side panel is then formed into a "zero tension" stretch laminate. (Alternatively, the elastic panel member may be operatively attached in a stressed condition and then subjected to mechanical stretching, although this is not as preferred as a "zero tension" stretch laminate). As used herein, the term "zero stress" stretch laminate refers to a laminate composed of at least two sheets of material that are secured to one another along at least a portion of their coextensive surfaces. while they are in a substantially unstressed condition ("zero stress"); one of the sheets comprising a material that is stretchable and elastomeric (i.e., it will substantially return to its unstressed dimensions after an applied tension force has been released) and a second sheet that is stretchable but not necessarily elastomeric), such so that when stretching the second sheet will be, at least to a degree, permanently elongated in such a way that when releasing the applied tension forces, it will not fully return to its original, non-deformed configuration. The resulting stretch laminate is thus made elastically extensible at least up to the point of initial stretch in the initial stretch direction. Particularly preferred methods and apparatuses used to make the stretch laminates use indentation corrugation rollers to mechanically stretch the components. Particularly preferred apparatuses and methods are described in U.S. Patent No. 5,167,897 issued to Weber et al. On December 1, 1992; ios patent United States No. 5,156,793 issued to Buell et al. On October 20, 1990; and in U.S. Patent No. 5,143,679 issued to Weber et al. on September 1, 1992. The web 38 acts to mechanically create adjustment forces in the notch diaper 20 when placed on the user, to maintain the diaper grooving on the wearer even when loaded with the exudates of the weave, in this way keeping the absorbent core in close proximity to the wearer, and to distribute the dynamically generated forces during use around the waist, thus providing supplemental support for The absorbent core loosens or ablates the absorbent core in the mid panel of the notch diaper. The band is designed to be elastically extensible in certain segments and at least elastically extensible, preferably elastically contractible in other segments around the waist opening; to be elastically extensible around a part of the leg opening; and so as not to pucker or bulge in the middle panel where the absorbent core is located. The elastic extension capacity of the band also has a "strength / extension wall", beyond the Which the band will not stretch elastically in order to allow the napkin to be more easily applied, since the diaper will not stretch excessively thus allowing the product to slide more easily over the buttocks. This "wall strength / extension" is especially important for young children who self-access the product and would be unable to pull and completely place a fully stretchable product on their buttocks. The band also manipulates the tensions of best use with the webs that surround the absorbent core. The resulting diaper is less cumbersome in its fit around the user's waist, the lack of puckering or shrinkage in the band over the absorbent core in combination with the continuity of the band through the absorbent core, also provides the improved fit by providing a Normal continuous force based on the stresses generated in the band, which tend to press the absorbent core against the core during use. In this way, the absorbent core is maintained in a narrower, more comfortable and less separate way than those diapers that provide elastic shrinkage or gathering over the area of the absorbent core, or those that do not provide a band to concentrate within the space and distribute Through space the stresses of the surrounding area of the absorbent core. The seam panels 66 and 66 'are those parts designed to be braced or joined together by the manufacturer, to form the waist opening and the leg openings 34 defined. As shown in Figure 2, the seam panels 66 and 66 'extend laterally outward from the respective side panels 46 and 48 toward the side edge 72 or 72' and generally extend longitudinally from the end edge 70 or 70 'towards leg edge 71 or 71 ', respectively. The sewing panels are preferably an extension of the chassis layer and other elements such as the web layers and the topsheet, or any other combination of these elements. In a preferred embodiment, each seam panel is formed by parts of the chassis layer, the web layers, the elastic panel members, and the barrier layers of the top sheet, (in the seam panel, the laminate The stretch is preferably not activated by mechanical stretching, although it may be provided, if desired, with additional extension capacity in this region In a more preferred embodiment, the seams 32 have a predetermined seam pattern such that the seam can be open by tearing easily when using the tear-open tab 31. Preferably, the seam 32 comprises an intermittent pattern of an individual junction or junctions bunched into clusters 4a, 4b 4c and 4d as shown, for example, in Figure 6. In this mode, sewing 32 It comprises 4 groups 4a-4d. Other suitable seams can have any number of groups such as two, three, five or more. Any form of union and / or group can be used while the seam can easily be opened by tearing when using the tear-open tab 31. Preferred union forms and / or groups include a circle, an oval, a triangle and a rectangle The spacing between the adjacent groups 4a-4d creates spaces or unattached portions 5a-5c in the seam 32. When the diaper 20 is used, the seams 32 tend to bend or buckle with the movement of the wearer. This buckling of the seams 32 in the gaps between the adjacent groups creates channels that allow air to move in and out of the diaper during use to ventilate the diaper. In this way, the portion not attached to the seam 32, (ie, the sum of all the individual separation distances), determines the breathability of the seams, and thus the breathability of the diaper 20. As the unattached portion of the seam 32 increases thus does the breathability of the diaper. However, since the unattached portion of the seam 32 increases, the strength of the seam 32 decreases. Preferably, the unattached portion of the seam 32 varies from about 20% to about 65% of the total length of the seam, as measured from the leg opening 34 toward the waist opening 36 along the seam 32. Examples of suitable seams have an unbonded portion comprising from about 30% to 35% or 40% of the total length of the seam. Unbonded portions below about 20% are generally not desirable since they do not allow a sufficient amount of air to enter the diaper, unbound portions above about 65% are generally not desirable, as these allow between sufficient amounts of air to vent the diaper, but they are not strong enough to withstand the forces and high stresses placed on the diaper during use.

Preferred sewing patterns may include different seam strength patterns which provide variable bond strengths between seam panels 66, such that the seam can be easily torn open when using the tear-open tab. In the preferred embodiments, this control of the bonding resistances can be produced by changing certain amounts of polymeric material contained in the seam panels 66. To increase the bond strength, for example, the amount of polymeric material contained therein can be increased. in the elements forming the sewing panels 66, by using nonwoven materials of higher basis weight, thicker plastic films, or by introducing layers of additional materials to the seam panels 66. For example, plastic films can be attached or the nonwoven webs in the sewing panels 66. Alternatively, the The layers forming the diaper can be extended beyond the attempted seam area and folded back over the seam panel to introduce additional layers of the seam panels. Examples of these types of sewing are discussed in the aforementioned U.S. Patent No. 5,236,430. In preferred embodiments, the tear opening tab 31 may be placed anywhere along the edge of the seam panel 66. In the embodiment shown in Figure 6, the tear-open tab 31 is placed in a tightly portion extending outward from separation 5a, which is approximately equally close to both of groups 4a and 4b. Preferably, the tear opening tab position 31 is biased between the leg opening 34 and the waist opening 36. In a preferred embodiment, the position of the tear opening tab is closer to the leg opening 34 that towards the waist opening 36. In a more preferred embodiment, the position of the tear opening tongue 31 is closer to the opening 36. that towards the leg opening 34 as shown in Figure 6. The predisposed position of the tear opening tongue 31 indicates to the user from which part he or she should begin to tear open the diaper with the fingers. Figure 7a shows the overlapped seam structure 32 formed by joining the seam panels 66. In this Figure, one of the seam elements 32 is depicted in an exaggerated manner in terms of its thickness and width for the purpose of explanation. The arrows F1 and F2 show the forces that are generated when the diaper 20 is used, thus applied to the seaming element 32 in the seam panels 66 and 66 'through the front and rear side panels 46 and 48. The The overlapping seam structure provides a necessary stitching resistance, which is required to maintain the diaper notching on the wearer's waist area. Figure 7B shows the forces F3 and F4 applied to the tear opening tongue 31 and the side front panel 46, respectively, when the notch diaper is tear open during removal of the wearer's diaper. Since the opposing forces F3 and F4 function effectively to separate the seam panel 66 from the side front panel 46 of the seam panel 66 'of the side rear panel 48- The predisposed position of the tear opening tab 31 causes a concentration of the tearing opening force F3 in the specific seaming element 32, which is placed closer towards the leg opening 34 or the waist opening 36. In this way, the notch diaper 20 can be torn open from the leg opening 34 or the waist opening 36 by applying a small amount of user force. In the most preferred embodiments, the notch diaper 20 further comprises an elimination or waste means 33 attached to the tear opening tab 31 to allow the notch diaper to be secured in a configuration that provides convenient removal. A preferred example of the elimination medium 33 is shown in Figure 8 In the preferred embodiments, the tear opening tab 31 has an inner surface 35 and an outer surface 37 (shown in Figure 9). The removal means 33 are attached to the inner surface 35 of the opening tab by Ripping 31 in such a way that the disposal means 33 are placed between the tear opening tab 31 and the side front panels 46, and hidden therebetween as shown in Figure 1 The disposal or disposal means 33 can be any material which may allow the notch diaper 20 to be secured in a configuration that provides convenient removal In the preferred embodiments, the removal means is a matepal which may be coupled with or attached to at least a portion of the post-tensioner sheet 22 or to a of the front and side postspor panels 46 and 48 for removal In a preferred embodiment, the means of removal 33 comprise an element d e mechanical fastening, which constitutes a mechanical fastening system with the back sheet 22 for disposal In a preferred alternative embodiment, the disposal or disposal means 33 comprise a mechanical fastening element that constitutes a mechanical fastening system with one of the panels Front and Side Pole 46 and 48 for Disposal The mechanical fastening element can comprise any known means for achieving a closure such as buttons, fasteners, hook fastening materials, or pzo fastening materials.

The hook fastening material is intended for coupling with the fibrous elements of a curl fastening material, which is formed on or on the backsheet 22 or on one of the front and rear panels 46 and 48. The base can be joined to the tear opening tongue 31 by any suitable means. In the preferred embodiments, these are directly bonded to the inner surface of the tear-open tab 31. In other preferred embodiments, the backsheet 22 or the rear front panels 46 and 48 comprise a mooring component (not shown), at least in the expected mooring portion of the disposal means 33 for disposal. The mooring component can be coupled with or attached to the removal means 33. The mooring component can be manufactured from a wide range of materials and configurations capable of securely coupling to the coupling component. For example, the mooring component may comprise identical complementary elements, or different complementary elements. As used herein, the term "identical elements" is used to define mechanical fastening systems where the coupling elements of the coupling component and the clamping component comprise the same configuration and structure. Different complements are used herein to designate a system in which the coupling component is different from the mooring component, but is capable of coupling with it. In a preferred embodiment, the mooring component comprises a plurality of fiber elements, such as a terry fastening material, which engage with the coupling elements of the waste or disposal means 33.
