Description

ABSORBENT ARTICLE THAT HAS A SYSTEM OF IMPROVED MECHANICAL CLAMPING.

FIELD OF THE INVENTION The present invention relates to absorbent articles such as diapers incontinence pads and diaper holders and the like, and more particularly, the present invention relates to absorbent articles having an improved mechanical fastening system.

BACKGROUND OF THE INVENTION Infants and other incontinent individuals use absorbent articles such as diapers to receive and contain urine and other body exudates. The absorbent articles work either to contain the discharged materials, or to isolate them from the user's body and the user's garments and bedding. Disposable absorbent articles having many different basic designs are known in the art. For example, Patent E.U.A. No. Re. 26,152, issued to Duncan et al. On January 31, 1967, describes a disposable diaper that has widely accepted commercial success and acceptance. The Patent E.U.A. No. 3,860,003, issued to Buell on January 14, 1975, discloses a disposable diaper of elasticated leg bending, which has a commercial success and widely accepted acceptance. Absorbent articles such as diapers generally include some type of fastening system or securing system for securing the diaper or absorbent article to the wearer. The mechanical fastening system, such as hook and loop system, have been used in absorbent articles in the past. However, several limitations have prevented the general commercialization of these systems on disposable absorbent articles. The limitations for the commercialization of mechanical fastening systems in disposable absorbent articles include the cost of the system and the functionality of this system. Typically, the cost and functionality of the system is a trade. In other words, greater functionality and performance can be achieved by using more expensive materials. In general, the hook and loop systems fail in the "detachment" mode. For example, a detachment mode exists when one component remains static, while the other component is removed or pulled out of the first component sequentially. When the two joining components, such as a plurality of hooks and a plurality of clips, are disengaged in the release mode, the hooks and clips are progressively separated. That is, each row or line of hooks disconnects a little at a time until all the hooks are disengaged from the respective clips. The development of the detachment of hook and loop systems is very sensitive to the cost / development relationship. Generally, to obtain a higher detachment, a hook of higher basis weight can be used which finally moves to more hooks, greater thickness of fabric and greater total cost, therefore, it would be advantageous to provide a disposable article so of improved detachment. Therefore, it is an object of the present invention to improve the development of the detachment mode of the mechanical fastening systems, such as the hook and loop systems in the hook and loop systems in the disposable absorbent articles.

BRIEF DESCRIPTION OF THE INVENTION The present invention provides absorbent articles such as disposable diapers, incontinence briefs, diaper carriers and the like having a unique fastening system. Said absorbent articles have longitudinal edges, end edges, a front waist portion, a rear waist portion, an outer surface and an inner surface. The absorbent articles comprise a containment assembly comprising a liquid-permeable top sheet, a liquid-impermeable back sheet attached to the top sheet, and an absorbent core placed between the top sheet and the back sheet. The absorbent core has lateral edges and waist edges. The absorbent article includes a fastening system having a securing member disposed adjacent each longitudinal edge in the rear waist portion and at least one landing member disposed in the front waist portion. The securing member includes a plurality of hooks and the landing member includes a plurality of clips that are engageable with the hooks of the securing member. The landing member is secured to the backsheet at the front waist portion around its periphery along the peripheral seal lines. The landing member may include a plurality of slits. The landing member can be secured to the backsheet by means of an adhesive, sonic joint or by hot sealing. The portion of the backsheet adjacent to the landing member is preferably not attached to the adjacent layer immediately, such as the absorbent core. The landing member is preferably a woven or nonwoven web. The hooks of the securing members may be connected in a single direction or in a multiplicity of directions.

DETAILED DESCRIPTION OF THE INVENTION As used herein the term "absorbent article" refers to devices that absorb and contain exudates from the body, and more specifically refers to devices that are placed against or close to the user's body to absorb and contain the various discharged exudates. for the body. The term "disposable" is used herein to describe absorbent articles, which do not intend to be washed, or otherwise restored or reused as an absorbent article (ie, they are intended to be discarded after a single use, and preferably , to be recirculated, composed or otherwise placed in an environmentally compatible manner). An "unitary" absorbent article refers to absorbent articles, which are formed of separate parts joined together to form a coordinated identity, so that they do not require separate manipulated parts as separate support and liner. A preferred embodiment of an absorbent article of the present invention is the disposable absorbent article diaper 20, shown in Figure 1. As used herein, the term "diaper" refers to an absorbent article generally used by infants and by persons incontinent that is used around the lower back of the user. However, it should be understood that the present invention can also be applied to other absorbent articles, such as incontinence briefs, incontinence underwear, diaper liners and liners, feminine sanitary garments, trainers and the like. Figure 1 is a plan view of the diaper 20 of the present invention in a non-contracted, extended (ie, with the elastic induced downward contraction) state, the portions of the structure being cut to more clearly show the construction of the diaper 20, and the portion of diaper 20 which looks away from the wearer, the outer surface, looking at the observer. As shown in Figure 1, the diaper 20 preferably comprises a liquid-permeable top sheet 24, a liquid-impermeable backsheet 26 attached to the topsheet 24, and an absorbent core 28, positioned between the topsheet 24 and the top sheet 24. back sheet 26, elastic leg cuffs 32, a front waist portion 34, a rear waist portion 35 and a generally multiple fastening system designated 36. The diaper 20, shown in Figure 1, has an outer surface 49, an inner surface 54 opposite the outer surface 49, and a periphery 60, which is defined by the outer edges of the diaper 20, wherein the longitudinal edges are designated with the number 62 and the end edges are designated with the number 64. The inner surface 54 of the diaper 20, comprises that portion of the diaper 20, which is positioned adjacent the wearer's body during use (i.e., the inner surface 54, is generally formed by at least a portion of the topsheet 24 and the other components attached to the upper sheet 24). The outer surface 49, comprises that portion of the diaper 20, which is positioned away from the wearer's body (i.e., the outer surface 49, is generally formed by at least a portion of the back sheet 26 and the other components attached to it. the back sheet 26). Figure 1 shows a preferred embodiment of the diaper 20, in which the topsheet 24 and the backsheet 26 have length and width dimensions generally greater than those of the absorbent core 28. The topsheet 24 and the backsheet 26, extend beyond the edges of the absorbent core 28, to thereby form the periphery 60 of the diaper 20. Since the topsheet 24, the backsheet 26, the absorbent core 28, can be assembled in a variety of well-known configurations, the configurations of the diaper are generally described in the US Patent No. 3,860,003, issued to Kenneth B. Buell, on January 14, 1975, Patent E.U.A. 5,151,092 issued to Kenneth B. Buell, on September 29, 1992, Patent E.U.A. 5,196,000 issued to Clear et al. On March 23, 1993. Each of these patents is hereby incorporated by reference. Figure 2 is a cross-sectional view of the diaper 20, taken along the sectional line 2-2 of Figure 1 in the first waist portion 34. Figure 2 shows the construction of the fastening system 36, in the front waist portion 34. The fastening system 36 in the front waist portion 34 includes a landing member 40 secured to the back sheet 26 to form a portion of the outer surface 52. The landing member may be a fabric material woven or nonwoven, manufactured to have an elevated hook construction in which the fabric is stabilized, i.e. the individual hooks are erect from the base of the fabric. The landing member 40 may also be of any suitable material having non-woven hooks on it. A suitable landing member is a woven material manufactured by Guilford Mills of New York, and marketed by Guilford Loop 18904 or Loop 34072. Other suitable members are described in U.S. Patent No. 5,256,231, issued to Gorman et al. October 1993, and the US Patent No. 5,032,122 issued to Noel et al. On July 16, 1991. Each of these patents is incorporated herein by reference. The landing member 40 is secured to the front waist portion 34 of the backsheet 26 such that the hooks extend outward from there. The geometrical shape of the landing member 40 may be of any desired shape such as rectangular, irregular, diamond, triangular. circular, oval, chevron or similar. The landing member 40, shown in Figures 1 and 2 is generally rectangular in shape. The landing member 40 is secured to the backsheet 26 around its periphery along the peripheral seal lines 41. Accordingly, the portion of the landing member 40, within the peripheral seal lines 41, is unattached to the backsheet 26 and is free to move in relation to the backsheet 26, and is free to move in relation to the backsheet 26. Adhesives that have been found suitable for attaching the landing member 40 to the backsheet 26, include, but are not limited to hot melt adhesives Findley Hot Melt H2031 or H2085, manufactured by Findley Aadhesives of Wauwatosa, Wl. The landing member 40 may also be attached to the backsheet 26, along the periphery seal lines 41, by sonic joins or hot sealing techniques, known in the art. The peripheral seal lines 41, are shown in Figure 1, as being continuous around the total periphery of the landing member 40. However, the seal lines do not have to be continuous and may be discontinuous or interrupted. The securing system 36 also includes a securing member 50 disposed adjacent each longitudinal edge 62 in the rear waist portion 35. The securing member 50 includes a plurality of hook members 52 for coupling a plurality of the loop members. on the landing member 40. The hook members 52 can face in a single direction or can be oriented in multiple directions. For example, one set of rows of hook members 52 can look up while the other set of rows can have its hook member facing in an opposite direction. Alternatively, the individual hook members 52 can be oriented in any number of different directions as desired. The hook members 52 may have any desired geometry or shape, such as, hooked, mushroom-shaped or T-shaped, and may be made of any suitable material, such as nylon or polyester. A preferred hook material is manufactured by The Bostik Company of Middleton, and sold as Bostik 7199 Hotmelt Polyester, hot melt polyester. Examples of hooks and methods for making them are described in the commonly assigned U.S. Patents. No. 5,058,247 issued to Thomas et al., October 22, 1991, US Pat. No. 5,116,563 issued to Thomas et al., May 26, 1992, US Patent No. No. 5,180,534, issued to Thomas et al. On January 19, 1993, and Patent E.U.A.No. 5,230,851, issued to Thomas on July 27, 1993. Each of these patents is incorporated herein by reference. The hooks 52 project from and are secured to a substrate of flexible material. A suitable substrate material is a 1.0 mil thick polyester film available from the disposable product division of 3M, St. Paul. MN. To secure the diaper to the wearer, the hooks 52 of the securing member 50 are secured to the clip of the landing member 40 around the wearer's waist. The nubs 52 engage the clips of the landing member 40 to secure the waist portions of the diaper. Upon the separation of the hooks 52 from the clips in the landing member 40, the portion of the landing member 40, which is inside the peripheral seal lines 41 and is not attached to the backsheet 26, will lift and separate the the backsheet 26, resulting in an increase in the adhesion force between the hooks 52 and the clips of the landing member 40. Referring now to Figure 3, the "S" line of the graph illustrates the adhesion force of a conventional hook and loop system in which the total surface of the landing member is secured to its substrate. In contrast, line "P" of the graph illustrates the adhesion force of a hook and loop system of the present invention where the landing member is secured to its substrate around its periphery along the seal lines peripheral. As can be seen from Figure 3, the adhesive force of the hook and loop system of the present invention, line "P", is significantly greater than the adhesion force of the conventional hook and loop system, line "S". Without being bound by any specific theory or mechanism, it has been found that the increase in adhesion strength results from the peripheral joining of the landing member 40 to the backsheet 26, which allows a portion of the landing member within the peripheral seal. , lift and separate from the back sheet 26, upon separation of the securing member 50 from the landing member 40. Figure 4, is a fragmented plan view of an alternative embodiment of disposable diaper of the present invention. The disposable diaper 120 includes a landing member 140 in the front waist portion 134. The landing member 140 is secured to the backsheet 126 to form a portion of the outer surface of the diaper 120. landing 140 to the backsheet 126, around its periphery along the peripheral seal line 141. The landing member 140 includes a plurality of clips that engage the hooks 52 of the securing member 50 to securely secure the waist position of the diaper. Upon the separation of the hooks 52 from the clips of the landing member 140, the portions of the landing member 140, not secured to the backsheet 126, will rise and separate from the backsheet 126. In addition, the slit view 136 on the landing member 140, will allow for even greater uniform separation and distortion of the landing member 140, thereby increasing the adhesion force of the mechanical fastening system. In order to maintain the integrity and appearance of the landing member 140, it may be desirable to use an elastomeric adhesive to secure the portions of the landing member 140 within the peripheral seal lines 140 to the backsheet 126. By using an elastomeric adhesive, the portions of the landing member 140 adjacent the slits 136 will substantially return to their non-deformed condition after the separation of the clips from the landing member 140 from the hooks 52. In order to further increase the adhesive force of the landing system. According to the present invention, it may be desirable to have the backsheet portion 26 adjacent the landing member not attached to the immediate adjacent layer, for example the absorbent core 28. By having the adjacent backsheet portion, the landing member is not attached to the immediate adjacent layer, a posterior sheet will raise and lift independently of the landing member, which will also raise and lift upon the occurrence of the separation of the hooks from the clips of the landing member, thereby further increasing the grip strength of the restraint system. In another embodiment of the present invention, the adjacent backsheet portion of the landing member is not attached to the immediately adjacent layer even though the landing member is secured to the backsheet by techniques known in the art. For example, the total surface or substantially the total surface of the landing member can be secured to the backsheet. The backsheet and the landing member will raise or lift in unison upon separation of the hooks from the clips of the landing member, thereby increasing the grip force of the fastening system. The containment assembly 22 of the diaper 20, is shown in Figure 1 as comprising the main body (chassis), of the diaper 20. The containment assembly 22, comprises at least one absorbent core 28 and preferably an outer cover layer that comprises the top sheet 24 and the back sheet 26. When the absorbent article comprises a separation support and a liner, the containment assembly 22, generally comprises the separator and the liner (i.e., the containment assembly comprises one or more layers). of material to define the support, while the liner comprises an absorbent composite such as a topsheet, a backsheet, and an absorbent core). For sanitary absorbent articles, the containment assembly 22 comprises a main structure of the diaper with other aspects added to form the composite diaper structure. Accordingly, the containment assembly 22 for the diaper 20, generally the topsheet 24, the backsheet 26, and the absorbent core 28. The absorbent core 28 can be any absorbent member, which is generally compressible, comfortable and non-irritating to the wearer's skin, and capable of absorbing and retaining liquids, such as urine and other exudates from the body. As shown in Figure 1, the absorbent core 28 has a garment-facing side, a body surface, side edges, and waist edges. The absorbent core 28 can be manufactured in a wide variety of sizes and shapes (v, gr., Rectangular, hourglass-shaped, "T" -shaped, asymmetrical, etc.), and a wide variety of materials liquid absorbers commonly used in disposable diapers and other absorbent articles, such as crushed wood pulp, which is generally referred to as air felt. Include examples of other suitable absorbent materials, curly cellulose wadding; meltblown polymers, including coform; hardened, modified or chemically entangled cellulosic fibers; fabric including fabric wraps and fabric laminar units; absorbent foams; absorbent sponges; superabsorbent polymers; absorbent gel materials; or any equivalent material or combinations of materials. The configuration and construction of the absorbent core may vary (e.g., the absorbent core may have variable gauge zones, a hydrophilic gradient, a superabsorbent gradient, or areas of low average density and weight gain with a lower average basis; may comprise one or more layers or structures). However, the total absorbent capacity of the absorbent core 28 must be compatible with the design load and intended use of the diaper 20. In addition, the size and absorbent capacity of the absorbent core 28 may be varied to accommodate users varying from infants. even adults. Examples of absorbent structures for use as the absorbent core 28 are described in the U.S.A. 4,610,678 issued to Weisman et al. On September 9, 1986; patent of E.U.A. 4,673,402 issued to Weisman et al. On June 16, 1987; patent of E.U.A. 4,888,231 issued to Angstadt on December 19, 1989; and the patent of E.U.A. 4,834,735, issued to Alemany et al. On May 30, 1989. The backsheet 26 is positioned adjacent the garment facing surface of the absorbent core 28 and preferably is attached thereto by attachment means (not shown) such as those well known in the art. . For example, the backsheet 26 can be secured to the absorbent core 28 by a uniform, continuous layer of adhesive, a patterned layer of adhesive, or an array of separate lines, coils, or spots of adhesive. The adhesives that have been found satisfactory are manufactured by H. B. Fuller Company of St. Paul, Minnesota and they are sold as HL-1258. The attachment means preferably will comprise an open pattern web of adhesive filaments as described in the U.S.A. No. 4,573,986 issued to Minetola et al. On March 4, 1986, more preferably several adhesive filament lines wound in a spiral pattern as illustrated by the apparatus and methods shown in US Pat. 3,911,173 issued to Sprague, Jr. on October 7, 1975; patent of E.U.A. 4,785,996 issued to Ziecker et al. On November 22, 1978; and patent of E.U.A. 4,842,666 issued to Werenicz on June 27, 1989. Each of these patents is incorporated herein by reference. Alternatively, the joining means may comprise heat bonds, pressure joints, ultrasonic joints, dynamic mechanical joints, or any other joining means or combinations of these joining means as are known in the art. The back sheet 26 is impervious to liquids (e.g., urine) and preferably manufactured from a thin plastic film, although other flexible liquid impermeable materials may also be used. As used herein, the term "flexible" refers to materials that are comfortable and readily adapt to the shape and contours of the human body. The backsheet 26 prevents the exudates absorbed and contained in the absorbent core 28 from wetting the articles that are in contact with the diaper 20, such as bed sheets and underwear. In this way, the backsheet 26 may comprise polymeric films of woven or nonwoven material, such as polyethylene or polypropylene thermoplastic films, or mixed materials, such as a nonwoven material coated with a film. Preferably, the backsheet is a thermoplastic film having a thickness of about 0.012 mm (0.5 millimicrons) to about 0.051 mm (2.0 millimicrons). Particularly preferred materials for the backsheet include RR8220 blown films and RR5475 cast films, such as those manufactured by Tredegar Industries, Inc. of Terre Haute, IN. Preferably, the backsheet 26 is etched and / or finished to matte to provide a clothing type appearance. In addition, the backsheet can allow vapors to escape from the absorbent core 28 (ie, be breathable), while still preventing the exudates from passing through the backsheet 26. The topsheet 24 is positioned adjacent to the surface 56 that faces the body of the absorbent core 28 and is preferably attached thereto and the backsheet 26 by attachment means (not shown) such as those known in the art. Suitable attachment means are described with respect to the attachment of the backsheet 26 to the absorbent core 28. As used herein, the term "attached" refers to configurations by means of which one element is directly secured to another element by fixing the element directly to the other element, and configurations by means of which the element is indirectly secured to the other element by fixing the element to the intermediate member (s) which are instead fixed to the other element. In a preferred embodiment of the present invention, the topsheet 24 and the backsheet 26 are directly bonded together at the periphery of the diaper 60 and are indirectly bonded together by attaching them directly to the absorbent core 28 by the attachment means (not shown) . The upper sheet 24 is comfortable, soft feeling and non-irritating to the user's skin. In addition, the topsheet 24 is permeable to liquid allowing liquids (e.g., urine) to easily penetrate through its thickness. A suitable top sheet 24 can be made from a wide variety of materials, such as porous foams; cross-linked foams; plastic films with opening; or woven or nonwoven webs of natural fibers (e.g., wood or cotton fibers), synthetic fibers (e.g., polyester or polypropylene fibers), or a combination of natural and synthetic fibers. The topsheet 24 is preferably made of a hydrophobic material to isolate the wearer's skin from the liquids contained in the absorbent core 28. There are a number of manufacturing techniques that can be used to manufacture the topsheet 24. For example, the sheet upper 24 may be a non-woven web of spunbonded, carded, wet-stretched, meltblown, hydroentangled, combinations of the above, or the like. A suitable top sheet 24 is carded and thermally bonded by means well known to those skilled in the cloth art. A satisfactory top sheet 24 comprises long polypropylene fibers as manufactured by Veratec, Inc., a division of the Division of International Paper Company, of Walpole, Mass., Under the designation of P-8. The diaper 20 preferably further comprises elastic leg cuffs 32 to provide improved containment of liquids and other exudates from the body. Each elastic leg cuff 32 can comprise several different modalities to reduce the runoff of exudates from the body in the leg regions. (The fold of the leg can also be referred to sometimes as leg frames, side flaps, barrier folds, or elastic folds). The patent of E.U.A. 3,860,003 discloses a disposable diaper that provides a contractible leg opening having a side flap and one or more elastic members to provide an elastic leg fold (packing fold). The patent of E.U.A. 4,909,803 issued to Aziz et al. On March 20, 1990 discloses a disposable diaper having "straight" elastic flaps (barrier folds) to improve containment of the leg regions. The patent of E.U.A. 4,695,278 issued to Lawson on September 22, 1987 discloses a disposable diaper having dual folds including a packing fold and a barrier fold. The diaper 20 preferably further comprises an elastic waist feature that provides improved fit and containment. The elastic waist feature is that portion or area of the diaper 20 that is intended to expand or contract elastically to dynamically adjust to the wearer's waist. The elastic waist feature preferably extends longitudinally outwardly from at least one of the waist edges of the absorbent core 28 and generally forms at least a portion of the end edge 64 of the diaper 20. Disposable diapers are generally constructed so that they have two elastic characteristics of waist, one placed in the rear waist portion and another placed in the front waist portion, although diapers can be constructed with a single elastic waist feature. In addition, since the elastic waist feature or any of its constituent elements may comprise a separate element fixed to the diaper 20, the elastic waist feature is preferably constructed as an extension of other diaper elements, such as the back sheet 26 or the top sheet 24, preferably both the back sheet 26 and the top sheet 24. The elastic waist feature can be constructed in a large number of different configurations, including those described in the US patent. 5,151,092 and in the patent E.U.A. 5,196,000; both of which are incorporated herein by reference. The diaper 20 is preferably applied to a wearer by placing one of the waist portions, preferably at the rear waist portion, under the user's back and directing the remainder of the diaper between the user's legs in such a way that the other portion waist, preferably the front waist portion, is placed across the front of the user. The hooks 52 of the securing member 50 of the fastening system 36, are secured from the clips of the landing member 40 of the diaper to effect a lateral closure. Although particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art, that various other changes and modifications may be made without departing from the spirit and scope of the invention. It is therefore ided to protect in the appended claims such changes and modifications as are within the scope of this invention.
