Abstract

An absorbent article having a liquid permeable topsheet layer, a backsheet layer and an absorbent structure positioned therebetween. The absorbent article has a front waist section, a rear waist section and an intermediate section interconnecting the two waist sections. An apertured liner at least partially defines a rear portion of the bodyside surface of the article and may include a bodyside apertured film layer. The topsheet layer at least partially defines a front portion of the bodyside surface and may be a fibrous material. The apertured liner defines a fecal target zone and enhances the ability of the absorbent article to contain low viscosity fecal materials and separate such materials from the skin of the wearer. The apertured liner may be formed by attaching an apertured film layer to a low density hydrophilic fibrous material. An absorbent body may also be attached to the underside of the apertured liner. A portion or all of the apertured liner may overlay the topsheet layer and the absorbent body can be positioned between the apertured liner and the topsheet layer. Attaching the apertured liner in an overlapping relation with the topsheet layer facilitates the manufacture of the absorbent article.

Description

413630 A7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs __B7__ V. Description of the Invention (1) Field of the Invention The present invention relates to an absorbent article that absorbs and contains body exudates. More particularly, the present invention relates to disposable absorbent articles, such as disposable diapers, child training pants and adult incontinence clothing, which are designed to include body exudates with low viscosity feces. Absorbent articles such as disposable diapers often use an absorbent shaft between a thin layer of liquid permeable layer adjacent to the wearer's body and a liquid-impermeable rear cover (defined as the outer surface of the garment). Liquid exudate (such as urine) penetrates the upper layer and is absorbed by the shaft, but the liquid-impermeable back cover helps to maintain a clean and dry outside surface ^ Traditional absorbent clothing is also commonly used to suppress and absorb solid and semi-solid exudates (Such as feces with significant changes in viscosity). Absorbent clothing typically includes elastic waistbands and trousers to prevent liquid and solid exudates from leaking. Traditional absorbent garments also include spin-offs or flaps on the legs or waist of the article to further prevent leaks. Some traditional absorbent garments also include a space with large voids into which solid waste is introduced. Recently, designs have been developed to include absorbent garments with a thin layer above the holes to provide the ability to increase the content of low viscosity materials, as exemplified by US Patent No. 5,342,338. number. SUMMARY OF THE INVENTION The present invention is to provide an improved absorbent article which can be efficiently manufactured and which provides suppression and absorption of low-viscosity feces by reducing contact between feces and the skin of the wearer. _ ί 丨! ί 装 i I (please read the notes on the back to fill out this page) Order ·-· This paper size applies to China National Standard (CNS) A4 (210x 297 mm) 4

Description of the invention (2) In a formation, the present invention includes (ie includes, but is not limited to) a bottom portion having a front waist portion, a rear waist portion, and a middle portion connecting the front and rear waist portions to each other. The bottom includes a rear cover plate layer, a liquid-permeable upper layer, and a basic structure disposed between the rear cover plate and the upper layer. When using the object, the body side surface of the object can be placed adjacent to the wearer. The absorbent article also includes a hole pad attached to the article, by which the hole pad is at least partially defined as the rear part of the side surface of the object, and the upper thin layer is at least partially defined as the front part of the side surface of the object. In some embodiments, the hole liner and the upper thin layer are separation members', either completely or part of the hole liner may overlap the upper thin layer. Another embodiment may include an upper thin layer with a necessary hole liner. The intercalation layer may also be arranged between the underlying basic absorbent structure and the hole liner to prevent the particulate matter in the basic absorbent structure from migrating outward. The hole liner may comprise a perforated film layer or a sheet product having a body-side perforated layer attached to a low density fiber layer. Some implementations of the present invention may also include an absorber disposed between the hole liner and the upper layer. The absorbent body may have an outer peripheral end (ie, a peripheral edge) which is substantially equal to the peripheral edge of the hole pad, thereby effectively cutting a sheet material of two materials' and attaching it to the top of the absorbent article. The invention provides many advantages. One advantage is that the holes of the hole pad disposed behind the body side surface allow the hole pad to block and suppress liquid and particulate feces below the side surface. As a result, the amount of skin contact with the wearer is reduced, resulting in improved comfort and skin health.

Description of the invention (3 ) Hole liner stacked on the body-side perforated film of more absorbent material. For a soiled piece of clothing, the resulting shape can be a cleaner and drier appearance and reduce the wearer's skin-to-feces contact. Absorption through the side layers of the pore liner body and contamination in combination with the absorption action reduces or removes fecal fluids, and these results are obtained because porous films are generally hydrophobic. In addition, the smooth surface provided by the perforated film layer reduces the number of visible feces, which are blocked on the slightly uneven surface on the side surface of the hole pad body. The fibrous absorbent material disposed under the perforated film layer provides a mechanism for absorbing and inhibiting feces from passing through the perforated film layer. All these functions have a tendency to reduce the tendency of feces to be stored on the body surface, thereby improving the performance and appearance of the hole liner. An additional advantage of the present invention is to provide a body-side surface including a front portion of a liquid-permeable upper sheet and a rear portion including a hole pad. This shape allows the thin layer and hole padding of the present invention to fully utilize individual different functions. Therefore, specific regions of the body-side surface of the absorbent article may have different material properties to improve the overall performance of the article. For example, a thin layer on a more hydrophilic fiber can be combined with a hole-forming structure formed by a hydrophobic porous film. It has been found that caregiver often uses the front part of the top sheet as an "initial wipe" to remove feces from the wearer's skin when soiled absorbent clothing is removed. Due to the texture of the partial fiber feed, the hydrophilic fiber material allows urine to pass quickly, 1 often forming an effective "initial wipe" material. In other words, the porous film is generally hydrophobic and resistant to fecal staining, but does not provide an efficient beta initial wipe.

The film obtained from Edison Plastics under the trade name XP313 4A is composed of 94% Rexene (with a melt index of 5.5 and 0.923 g / cc) and 6% Ampacet (a consistency of Ti02 consisting of 70% Ti02 and 30% LDPE). Holes are provided in the layer (64) in a suitable manner by pin rollers or other known techniques. The illustrated perforated layer (64) has an open area of 28%. Therefore, the pores in the diaper layer (64) in the diaper are about 28% of the open area of the body-side surface portion of the pore layer. Another number of open areas ranging from about 20% to 60% can also be effectively used as a perforated layer (64). The open area of the pores in the porous layer (64) ranges from about 4000 to 3000 microns in equivalent diameter, or about 400 to 1300 microns. The holes in the illustrated embodiment have an open area equal to the circular open area (approximately 700 microns in diameter). The pin roll manufacturing used to form the illustrated holes often introduces changes in the size and shape of individual holes. For example, due to subsequent material illustrations, initially circular holes can often become slightly elliptical. In another embodiment, the size and / or shape of the pores may be selectively varied. A single embodiment may include two or more individual groups of pores of different sizes or shapes. For example, the perforated layer (64) may include a fixed percentage of smaller holes with remaining holes (consisting of larger holes), where the smaller holes are similar in size and shape to another pierced hole, and the larger holes are It is also similar in size and shape to another hole.

A material includes a thermoplastic film having an open area and a nonwoven fibrous material. Foam-like materials (especially the closed cell foam-like material family with "skin") can also be effectively used as the porous layer (64). A perforated, thin foam-like material will generally have a "soft" feel, which is a beneficial characteristic of body-side surface materials. An additional material for the perforated layer (64) includes a thermoplastic netting which contains highly permeable areas of size. This network is manufactured by Na]] e Plastics, Inc., under the trade name Naltex, and is based in Austin, Texas. It is also possible to use a bi-planar filter mesh 'which is manufactured by the company's aet Specialty Net and Profile located in Saline, Mass. Porous layer (64) can also be treated to reduce adhesion and soiling of feces. For example, it can be resisted by adding protein, or by adding or adding hydrophobic properties to the material. These treatment methods include using fluorocarbons, Peng, PLEURONICS (three groups of common products of ethylene oxide, propylene oxide and ethylene oxide 'made by BASF, Germany), surfactants and other treatment methods, including ethylene oxide and other treatment methods of well-known technology. Ethylene-based materials (such as nonwovens) are more likely to require surface treatment to improve their hydrophobic properties than naturally hydrophobic film materials. The resistance of a fibrous material to a liquid's humidity or penetration depends on many factors. These factors include chemical nature, geometry, rough surface of the fiber, and capillary spacing of the material. A further advantage of the use of the film to form the porous layer (64) is that the film is stored on a smooth surface of the driver.

Description of the invention (2 3) The pores of the absorber can be formed individually, and are generally placed on the record, partly recorded or not recorded at all. The holes in 64) may all have similar records, or the holes in the absorbent body (68) may have different records stored in various percentages and different spatial distributions. On the upper Φί: supply the sheet material, and perform on the upper sheet unwinding (84). Similarly, the 'slush mud material avoids unwinding of the stratosphere (8 6). Hole liners and surge materials are attached to the opposite side of the upper layer using known techniques of cutting and placement modules (88) and (90). In the embodiment described here, the cutting and placing modules (88) and (90) operate in a similar manner. That is, the module cutting material is not applied to the hole liner or is a flowing material, and includes a roller rotating at least at a speed that is faster than the material loading speed. Due to the different speeds, when the roller in contact with the material is moved at a higher rotation speed than the material loading speed, the roller will create a distance between the material fragments, which is cut off from the loaded material and thereby allows the material fragments to attach to the space Another material in the arrangement. Before the upper thin layer is brought into contact with the application material, the 'bonding agent is not applied to the upper layer or the application material. Another method of attaching a piece of material used in a spaced relationship to the upper layer is also possible. The method of formula order is described by Boothe et al. In U.S. Patent No. 5,716,478; it was issued on February 10, 1998, and is incorporated herein by reference. As exemplified by this reference, the cutting and placing module can also utilize an eccentrically moving segment that rotates approximately coaxially. This moving fragment is defined as a cylindrical surface of less than 360 degrees, which allows the fragments to rotate in proportion to each other, and thereby allows the rotation speed of each fragment to be changed. In this way, a moving segment can introduce a material at the first rotation speed, and generally move on a paper scale that applies the Chinese National Standard (CNS) A4 specification (21〇χ 297 mm) ^ ^ ---- --- I ---------- ^ (Please read the notes on the back to fill out this page) 26 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 413630 A7 ___B7___ V. Description of the invention (24) Spacer pattern The material is a fabric that moves at a speed greater than the initial speed at which the material was attached to the fabric. As shown in the shape of the diaper (20), the cutting and placing modules (88) and (90) are queuing and the surge layer and hole pad are attached to the opposite side of the upper sheet, and the hole liner is attached to the face of the upper sheet On the surface of the body. It is recorded that the guide rods (92) and (94) are used in the ideal position for fixing the surge layer and hole gasket to the upper thin layer. The guide bar monitors the progession of the upper thin layer, and the advance length of the upper sheet can be removed or increased to provide a slight adjustment between the fragments of adjacent materials (applied to the thin layer above the guide bar described below). (96) is inserted between the cutting and placing module (90), which is used to apply the surge layer and the recording guide before the hole pad is attached. Another manufacturing method is illustrated in FIG. 8 which is similar to FIG. 7. The most significant difference between the methods illustrated in Figure 8 and Figure 8 is that the hole liner (62) is adhered to the absorbent layer before the absorbent article is assembled. A hole liner / absorber sheet product is provided on the roll of the sheet product unwind (98). By pre-cutting the off-line ground cavity liner (62) and the absorber (68) into thin sheets, an unwinding and a set of adhesive equipment (that is, a glue sprayer and rollers) can be removed from the diaper machine and located in the more Convenient offline location. The off-line laminate action facilitates the use of pre-existing diaper machinery to reduce the number of pieces of equipment (must be incorporated into pre-existing diaper machinery) and disposable cushioned disposable absorbent garments. Other alternative manufacturing methods can also be used. For example, the unwinding roller (98) illustrated in Figure 8 can be used to unwind only the hole liner (64) to make an absorbent article that does not include a low density fiber layer (66) or an absorbent layer (680.
