Abstract

The present invention relates to absorbent articles, in particular sanitary napkins or panty liners, which are manufactured for bonding to the undergarment of the wearer. Such products are typically coupled to the wearer's undergarment while the wearer has an undergarment stretched between the legs. In the extended position, the undergarment has an extended surface. As the undergarment is pulled up, the undergarment stretches and thus stretches the attached absorbent product. According to the present invention, the absorbent article shrinks the stretching of the undergarment in more than one direction, thereby reducing the wave shape or folding of the absorbent article.

Description

Shrinkable Sanitary Napkin {CONTRACTIBLE SANITARY NAPKIN}

Absorbent articles worn on the wearer's undergarment are known to significantly improve the performance of absorbent articles if their fixation, structural integrity and specific suitability for particular wear conditions can be ensured all the time during the use of the article. In this regard, a number of attempts have been made to provide absorbent articles with extensibility, elastic extensibility, high flexibility or, more generally, deformability that can produce products having the ability to adapt to the wearer's movement during use. Has been improved.

Thus, it is taught in the prior art to utilize the aforementioned elements to ensure the proper suitability of disposable absorbent articles, such as sanitary napkins or panty liners, to produce comfortable and high performance absorbent articles during use. Thus, products that are adapted to movement during use are advancing over time. However, absorbent articles are typically not provided directly to the wearing position in use, but adhere to the wearer's undergarment while the undergarment is twisted. Typically the undergarment is placed in a particular installation or application position and the undergarment is not similar to being pulled into the wearing position.

Typically, a sanitary napkin or panty liner is attached to the undergarment while the undergarment is in a pulled position between the wearer's legs. Conventional undergarments can be stretched and retracted, ie elastically stretched to provide good comfort and proper suitability during the wearing of undergarments and the use of such undergarments. In particular, the crotch region of the undergarment sometimes imparts elasticity in the cross direction and in the longitudinal direction. Thus, the undergarment in the pulled position may be in an extended form. When the disposable absorbent product is applied, the undergarment will stretch and be pulled into use.

If the undergarment shrinks, there can be several consequences. One of these is that for relatively stiff products, part of the attachment area is broken into pieces. Another thing is that very flexible products are wrinkled or twisted. However, the majority of products exhibit moderate behavior at these extremes, and have been found to crumple or crack early in use, resulting in unacceptable compatibility.

It is therefore an object of the present invention to provide a disposable absorbent article, in particular a sanitary napkin or panty liner, which can provide good suitability even after carrying out conventional application work. In particular, it is an object of the present invention to provide an absorbent article having persistence according to the movement and stress of the undergarment in order to maintain the wearer proximity of the undergarment itself. In particular, it is an object of the present invention to provide an absorbent article that can initially shrink when the absorbent article is placed in a worn position with an external force.

The present invention relates to absorbent articles, in particular sanitary napkins or panty liners, which are manufactured for bonding to the undergarment of the wearer. Such products are typically coupled to the wearer's undergarment while the wearer has an undergarment stretched between the legs. The undergarment is typically a pair of elastic, self-stretch fabric or woven panties. In this extended position, the undergarment has an extended surface. As the undergarment is pulled up, the undergarment stretches and thus stretches the attached absorbent product. In accordance with the present invention, the absorbent article shrinks the stretch direction of one or more undergarments to reduce the corrugation or folding of the absorbent article.

The present invention relates to an absorbent article bonded for use in the undergarment of the wearer. The article has a longitudinal axis and a transverse or intersecting axis and comprises three main elements, a top sheet which is liquid permeable, a back sheet which forms an outer surface in contact with the undergarment during use, and is inserted between the top sheet and the back sheet. And an absorbent core. The absorbent article also has panty fastening means provided on the outer surface of the backsheet for bonding the article to the undergarment of the wearer. The article according to the invention is shrinkable in at least one of a direction parallel to the longitudinal axis or a direction parallel to the transverse axis or a combination thereof. Since stretching of the undergarment is important in a direction substantially parallel to the longitudinal axis of the disposable absorbent article, a product that can shrink in at least this direction is a preferred embodiment of the present invention.

Particularly preferred disposable absorbent articles are sanitary napkins or panty liners having a maximum thickness of less than 5 mm, preferably less than 2 mm. In one embodiment according to the invention, the entire absorbent article comprising the topsheet, the backsheet and the absorbent core is corrugated or corrugated with corrugations or corrugations parallel to the transverse direction of the absorbent article.

The absorbent article according to the invention may comprise a release liner that protects the panty fixation means prior to use of the article. If the release liner is almost non-extensible and non-shrinkable, it is placed on a corrugated or corrugated absorbent product to protect the corrugated or wrinkled during manufacture, packaging, and transportation of the absorbent product until the release liner is split and used before installing the absorbent product in the undergarment. It is particularly preferable to.

One, some or all of the absorbent articles (top sheet, back) as long as the one or more inelastically extensible element (s) are provided in corrugations or corrugations substantially perpendicular to the same direction of extension of the elastically extensible element of the product. Sheet and absorbent core) are elastically extensible. This will provide a disposable absorbent article with the desired shrinkage and will also provide elasticity to the article. Thus, particularly preferred embodiments of the present invention when all the major elements of the article are mainly the top sheet, the absorbent core and the back sheet, are elastically extensible parallel to the longitudinal and transverse axes, individually and in combination thereof, whereas the absorbent article The entirety of the corrugations is corrugated or corrugated with corrugations or corrugations at least substantially parallel to the longitudinal axis of the absorbent article.

In a particularly preferred embodiment according to the invention, when the absorbent article is corrugated or corrugated as a means for imparting shrinkage, the panty securing means is preferably provided by a pressure sensitive adhesive which is preferably provided only on the corrugated or wrinkled outer contact surface of the backsheet.

The present invention will be described with reference to a sanitary napkin or pantyliner. However, it is equally well applicable to sanitary napkins or adult incontinence products worn on undergarments, and bonded to undergarments during wear of absorbent articles.

Absorbent articles according to the invention typically comprise three main components: a liquid permeable topsheet, a backsheet and an absorbent core. The absorbent core is enclosed by the backsheet and the topsheet, wherein the article is worn such that the exposed surface of the topsheet contacts the wearer of the absorbent article, while the exposed surface of the backsheet contacts the undergarment, and the article is a panty. By means of fastening attachment means. Typically this is an adhesive but can also be a mechanical attachment.

The present invention relates to the contractility of a product. The degree of shrinkage, as mentioned above, is determined by its individual amount of elongation, which is processed to provide the selectivity and shrinkage of the material with respect to the components of the product. The choice of the type, amount and treatment of the raw material in order to obtain shrinkage according to the present invention should be equivalent to other desired properties of the absorbent product, such as absorption capacity, absorption rate and surface dryness on the exterior of the topsheet during use, for example. It will be apparent to those skilled in the art.

Thus, the following description of the main ingredient materials of typical absorbent articles will provide a number of product variants that meet the shrinkage requirements in accordance with the present invention.

In addition to shrinkage, absorbent articles according to preferred embodiments of the present invention are elastically stretchable. As used herein, the term “elastically stretchable” will tend to restore the product to its non-extension or non-extension (or “original” size) when the stretching force is removed. However, it is not necessary to recover in all directions to its unextended size. If the absorbent article is elastically stretchable, it can stretch in one or two directions (non-parallel) in the plane of the article, ie essentially parallel to the garment contact surface.

Materials for shrinkable and elastically stretchable products may themselves be elastic or processed to provide elastic extensibility. In particular, in elastic backsheet materials, filament materials in combination with elastic topsheet materials, elastic strands, yarns or webs, as well as corrugated, corrugated or ring rolls of such materials can be used herein. Suitable materials and methods are known in the art and are described, for example, in U.S. Patent Application Serial No. 08/04 of February 4, 1994, which is specifically mentioned to facilitate the selection of materials when stretchable absorbent products according to the invention are produced. 192240 is described in detail.

In the following, non-limiting embodiments of the principal elements of an absorbent article that can be used in shrinking and preferably elastically extensible, non-extending designs are described.

Absorption Core

The absorbent core typically comprises (a) optionally a first fluid distribution layer; (b) optional but preferably a second fluid distribution layer; (c) a fluid storage layer; (d) a fibrous ("dust") layer optionally underlying the storage layer; And (e) other optional ingredients.

a. First fluid distribution layer

One optional component of the absorbent core according to the invention is the first fluid distribution layer. The first fluid distribution layer typically lies below the topsheet and is in fluid communication. The topsheet transports the captured physiological fluid to the first distribution layer for ultimate distribution to the storage layer. Transport of the fluid through the first distribution layer occurs along the length and width directions as well as the thickness of the absorbent article.

b. Optional second fluid distribution layer

A further preferred but preferred component of the absorbent core according to the invention is the second fluid distribution layer. The second distribution layer typically lies below the first distribution layer and is in fluid communication. The purpose of this second distribution layer is to easily capture fluid from the first distribution layer and to quickly transport it down the storage layer. This helps to make full use of the fluid capacity of the underlying storage layer.

c. Fluid storage layer

Positioned in fluid communication and typically lying below the first or second distribution layer is a fluid storage layer comprising a particular absorbent gelling material and / or other absorbent material, which may form a carrier matrix for the absorbent gelling material. Absorbent gelling materials are commonly referred to as "hydrogel", "superabsorbent" "hydrocolloid" materials. Absorbent gelling materials absorb such fluids upon contact with aqueous fluids, especially aqueous body fluids, and thus form hydrogels. These absorbent gelling materials typically can absorb large amounts of aqueous body fluids and can also retain such absorbed fluids under controlled pressure. These absorbing gelling materials are typically in the form of discontinuous, non-fibrous particles.

The fluid storage layer may only comprise absorbent gelling materials, or these absorbent gelling materials may be uniformly or heterogeneously dispersed in a suitable carrier or may only comprise absorbent carrier materials.

Suitable carriers are in the form of fluff, tissue or paper as commonly utilized in the absorbent core. Modified cellulose fibers (eg, reinforced cellulose fibers) can also be used. Synthetic fibers can also be used, cellulose acetate, polyvinyl fluoride, polyvinylidene chloride, acrylics (eg orlon), polyvinyl acetate, insoluble polyvinyl alcohol, polyethylene, polypropylene, polyamides (eg nylon) And polyesters, bicomponent fibers, ternary fibers, mixtures thereof and the like. Preferred synthetic fibers have from about 3 denier to about 25 denier per filament, more preferably from about 5 denier to about 16 denier per filament. Also preferably, the fibrous side is hydrophilic or treated hydrophilically. The storage layer may also include filler materials such as pearlite, diatomaceous earth, vermiculite and the like with low rewetting problems.

If unevenly dispersed in the carrier, the storage layer may be locally uniform, ie have a distribution gradient in one or multiple directions within the size of the storage layer. Heterogeneous distribution may also refer to a laminate of carriers containing partially or fully absorbent gelling material. If laminates are used they can be formed with or without absorbent gelling particles. In particular, thermally bonded air laminated fibrous sheets or laminates and / or thermally bonded wet laminated sheets or laminates have been found to be useful in the field of panty liners, especially when no absorbent gelling material is used.

Preferably, the storage layer comprises about 15 to 100% absorbent gelling material and 0 to about 85% carrier. More preferably, the storage layer comprises about 30 to 100% absorbent gelling material, most preferably about 60 to 100% and 0 to about 70% of carrier, most preferably 0 to about 40%.

Absorbent gelling materials suitable for use herein include mostly crosslinked, partially neutralized, partially polymerized polymer gelling materials that are often almost insoluble. This material forms a hydrogel upon contact with water. Such polymeric materials can be prepared from polymerizable, unsaturated, acid containing monomers. Unsaturated acidic monomers suitable for use in the preparation of the polymer absorbent gelling materials used in the present invention include those described in US Pat. No. 4,654,039 and licensed as RE 32,649. Preferred monomers include acrylic acid, methacrylic acid and 2-acrylamido-2-methyl propane sulfonic acid. Acrylic acid itself is particularly preferred for the preparation of polymeric gelling materials. Polymer components formed from unsaturated acid-containing monomers may be grafted onto other forms of polymer residues such as starch or cellulose. Particular preference is given to polyacrylate grafted starch materials of this form. Preferred polymeric absorbent gelling materials that can be prepared from conventional monomeric forms include hydrolyzed acrylonitrile graft starch, polyacrylate graft starch, polyacrylates, maleic anhydride based copolymers and combinations thereof. Especially preferred are polyacrylates and polyacrylate graft starches.

While the absorbent gelling material is typically in particulate form, it is contemplated that the absorbent gelling material may be in the form of macrostructures such as fibers, sheets or strips.

d. Optional fiber ("dust") layer

An optional component for inclusion in the absorbent core according to the present invention is a fibrous layer adjacent to and typically underlying the storage layer. The underlying fibrous layer is typically referred to as a "dust" layer because it provides a substrate for depositing the absorbent gelling material in the storage layer during fabrication of the absorbent core. In fact, when the absorbent gelling material is in the form of a laminate or a macrostructure (eg fiber, sheet or strip), this fiber "dust" layer need not be included. However, their inclusion is typically preferred for absorbent cores according to the present invention as they provide some additional fluid handling performance, such as quick wicking of the fluid along the length of the pad.

e. Other optional ingredients

The absorbent core according to the present invention may comprise other optional components generally present in the absorbent web. For example, the reinforcement scrims may be located in or between individual layers of the absorbent core. Such reinforcing scrims should be shaped particularly to not form interfacial barriers for fluid transport when located between individual layers of the absorbent core. Reinforced scrims, given the structural integrity normally occurring as a result of thermal bonding, are usually not required for the absorbent structure according to the present invention. However, when used they should allow for the desired shrinkage.

Another component which may be included in the absorbent core according to the invention, preferably provided in close proximity as part of the first or second fluid distribution layer, is an odor inhibitor. These may be selected from activated carbon or color coated activated carbon, suitable zeolites or clay materials may optionally be incorporated into the absorbent core, and in combination with any zeolite, absorbent gelling materials have been found to be useful. These components may be incorporated in any desired form but are often included as discrete, non-fibrous particles.

Top sheet

The topsheet is docile, soft to the touch and non-irritating to the wearer's skin. As indicated above, the topsheet material is also elastically stretchable in one or two directions. In addition, the topsheet is originally a fluid permissible fluid (eg, physiological fluids and / or urine) that can easily penetrate through its thickness. Suitable topsheets include woven and nonwoven fabrics; Polymeric materials such as perforated thermoplastic films, perforated plastic films and hydroformed thermoplastic films; Porous foams; Reticular foam; Network thermoplastic films; And a wide variety of materials such as thermoplastic scrims. Suitable fabrics and nonwovens can be constructed from natural fibers (such as wood or cotton fibers), synthetic fibers (such as polymer fibers such as polyester, polypropylene or polyethylene fibers) or combinations of natural and synthetic fibers.

Preferred topsheets for use in the present invention are selected from high-layer nonwoven topsheets and perforated film topsheets. Perforated films are particularly preferred for topsheets because they are permeable to body excretion and are also nonabsorbent and reduce the tendency to pass and rewet fluid through the wearer's skin. Thus, the surface of the formed film in contact with the body remains dry, thus reducing body contamination and creating a more pleasant feeling for the wearer. Suitably formed films are described in US Pat. No. 3,929,135; US Patent No. 4,324,246; US Patent No. 4,342,314; US Patent No. 4,463,045; And US Pat. No. 5,006,394. Particularly preferred microperforated film topsheets are described in US Pat. No. 4,609,518 and US Pat. No. 4,629,643. Preferred topsheets for the present invention are the formed films described in one or more of the above patents, and are marketed as sanitary napkins by The Procter & Gamble Company, Cincinnati, Ohio under the trade name "DRI-WEAVE".

Topsheets which do not have a uniform distribution of the liquid passages but which have only a portion of the topsheet comprising the liquid passages are also contemplated by the present invention. Typically such topsheets will have a liquid passageway oriented to produce a topsheet that is centrally permeable and peripherally impermeable to the liquid.

If the body surface is not hydrophilic, the body surface of the film topsheet formed to transport liquid through the topsheet more quickly may be hydrophilic. In a preferred embodiment, the surfactants are described in US patent application Ser. No. 07 / 794,745 filed November 19, 1991. On the other hand, the body surface of the topsheet can be made hydrophilic by treating with a surfactant as described in US Pat. No. 4,950,254, which is incorporated by reference.

Back sheet

The backsheet prevents the excretions absorbed and contained in the absorbent core from the wet product in contact with sanitary napkins such as panties, pajamas and undergarments. The backsheet is preferably impermeable to liquids (eg physiological fluids and / or urine) and is preferably made from thin plastic films, although other flexible impermeable materials may also be used. The backsheet needs to be compliant and will easily fit into the general shape and appearance of the body. The backsheet may preferably also have a specific ability to elastically stretch in one or two directions.

The backsheet may comprise a woven fabric, a nonwoven fabric, a polymer film (such as a thermoplastic film of polyethylene or polypropylene) or a composite material (such as a film coated nonwoven). Preferably, the backsheet is a polyethylene film having a thickness of about 0.012 mm to about 0.051 mm.

Exemplary polyethylene films are prepared by Clofei Corporation, Cincinnati, Ohio under trade name P18-0401 and Bisquin Division Ethyl Corporation, Terre Haute, Indiana under trade name XP-39385. The backsheet is preferably embossed and / or mated to provide a more woven appearance. Moreover, the backsheet can escape water vapor from the absorbent structure (ie, breathable) and also prevent the feces from passing through the backsheet. The use of perforated hydrophobic polymer films with directional liquid transport as described above for the topsheet towards the absorbent structure as a breathable backsheet for a pantyliner or sanitary napkin with a small amount of liquid for absorption, in particular according to their intended use It is possible.

contractility

According to the invention, the product as a whole shrinks the product immediately after it has been applied to the undergarment to adapt the initial stress inserted into the product by the usual application method. It is necessary to take into account that the sanitary napkin is placed in the undergarment at this point in a relaxed state or the undergarment itself is also pre-extended with a particular extension to accommodate the application situation.

This depends entirely on the user's individual habits and practices, and thus cannot give a globally valid answer to this problem, but I think it would be a different stress / strain situation than undergarment where the conditions under which the absorbent product is placed in the undergarment are fixed. do. The user cannot pre-stretch the product but can place it under these conditions by providing it with an elongated undergarment.

If such a product has wings or side flaps that are folded around the crotch edge of the undergarment, some stretches may also provide the product in the transverse direction. In the folding process, some users tend to pull on each wing so that the product is pre-extended to any extension. However, under normal use conditions, it is considered that no longitudinal or transverse pre-elongation exceeding the under garment occurs. Thus, the need for shrinkage varies depending on the application technique used by the individual user, but the basic requirements of shrinkage benefit many users.

In order to provide shrinkage, the absorbent article may be adapted such that the material used shrinks as a foam material, and the shrinkage or elongation can be adapted based on the foam structure of the material, and the fibrous structure that shrinks by modifying the fiber contacts is typically fibrous. Retain the structure. It is therefore possible to provide a key element of each absorbent article having shrinkage as a criterion for selecting a suitable material. In this regard, each individual component is necessary to provide at least minimal desired shrinkage. In addition, the way in which the materials are bonded to each other, such as adhesives, requires adaptation of such contractions in order not to show limiting the shrinkage factor beyond the minimum desired shrinkage. Another method for providing shrinkage allows for storage of the access material in the direction of the desired shrinkage. This may be provided by providing a material having a single or a series of corrugations or wrinkles. These corrugations or folds are instructed and designed to accommodate the external stresses approached by shrinking the undergarment in a form typically devised by the desired shrinkage without the contraction causing the corrugation or release of the panty fixation means from the undergarment. Will transform the product. Such corrugations or corrugations may be provided in the longitudinal or transverse direction or in two longitudinal and transverse directions to impart individually shrinkable articles in one or the other or both directions.

It is of course also possible to combine the inherent material shrinkage with structural shrinkage provided in the form of corrugations or wrinkles. As used herein, the term “waveform or wrinkle” refers to the presence of a series of continuous changes in the normal direction of the sheet plane. The "normal direction" of a plane is the direction perpendicular to the plane. Although the waveform is a continuous change in the normal direction of the plane of the sheet, the term "wrinkle or corrugated" as used herein refers to the folding or in other words the breaking change in the normal direction of the sheet plane. A series of wrinkles can also be used to stimulate the waveform and is approached by an infinite number of wrinkles from the theoretical point of view of the waveform.

In particular, the method of ring rolls for pantyliners can be used for the entire product to provide structural waveforms for shrinkage of the product as desired. In high speed manufacturing operations at least these ring-rolls require a material that is carefully selected by those skilled in the art, but there is no problem with the material selection and the desired shrinkage. Prior to combination, ring-rolls of individual materials may also be useful to provide products in addition to their shrinkage, which has flexibility and flexibility improvements over ordinary products. Ring-rolls are described in U.S. Patent Nos. 4,107,364, U.S. Patent 4,834,741, U.S. Patent 5,156,793, U.S. Patent 5,143,679, U.S. Patent 5,167,897, and U.S. Pat. It is described in more detail below. Waveforms are also well known and will be readily available to those skilled in the art. Waveforms may exist in the longitudinal and transverse directions of the absorbent article, but waveform techniques are being developed to provide a crosswise direction of the direction of material transport during manufacture of the article. Thus, ring-roll operation can be considered to provide a waveform in the direction of transport of the material during manufacture, while the waveform method will typically provide only a waveform in the vertical direction.

However, the term waveform or corrugation as used herein refers to the result of a ring-roll or waveform, regardless of the method used in the direction of transport of the material or in the direction perpendicular to it during manufacture.

The required amount of waveform or corrugation (defined by size and frequency) can be easily defined by simple trial and error to adapt the required shrinkage. This will depend on the bonding thickness and flexibility of the product. Those skilled in the art will also appreciate that the same waveform or wrinkle may be provided to again flatten or not or depend on other degrees of shrinkage. In particular, the overall shrinkage can be increased by stretching the corrugations or wrinkles of the product perpendicular to the lines of the corrugations or wrinkles.

Panties-fixed-adhesive

The backsheet typically forms a garment contact surface in which the panty anchoring adhesive is located. Panty-adhesive-adhesives may include any adhesive or glue used in the art for this purpose, with pressure sensitive adhesives being preferred. Suitable adhesives are Century A-305-IV, manufactured by Century Auchbus Corporation, Lock 34-2823, manufactured by National Starch Company, 3 manufactured by Sigma. Fuller H-2238ZP manufactured by Sigma 3153 and H. B. Fuller Company. Suitable adhesive fasteners are also described in US Pat. No. 4,917,697.

Other suitable panty-stick-adhesives are described in PCT International Publication WO 92/04000; It is shown in WO 93/01783 and WO 93/01785.

It should be understood that in particular adhesives need to support this performance because it is desirable to make a component that forms the garment contact surface of a sanitary napkin (and any underlying component) that is shrinkable in the wearer's panties. The panty anchoring adhesive is preferably applied to intermittent patterns, such as intermittent dots, intermittent strips, irregular or devised filament patterns, for example to shrink and / or extend sanitary napkins.

In addition to the adhesive, other types of fasteners may be used instead of or in addition to the adhesive. These other types of fasteners are arranged in a pattern similar to an adhesive. Such fasteners include, but are not limited to, conventional Velcro hook material or similar fasteners.

The optional protective side flap can have an optional fastener for additional protection. The optional protective side flap fastener can be any type of anchoring material herein. The fastener assists the protective side flap while remaining in a position after wrapping around the edge of the crotch surface of the protective side flap.

Prior to use of the absorbent article, the panty fixative adhesive typically protects against contamination and adhesion to any surface and is not preferred by protective cover means such as silicone coated release paper, plastic film or any other easily removable cover. . Protective cover means can be provided, for example, as single or multiple parts for covering individual adhesive areas.

Particularly in an embodiment according to the invention having a corrugation or corrugation in the backsheet (or the entire product), the part of the corrugation or corrugation directed outward from the article (ie the part of the backsheet which first comes into contact with the undergarment in use of the product). It is desirable to provide a panty sticking adhesive only onto the bed. In these embodiments, the protective covering means is preferably non-extensible and non-shrinkable material. The adhesive will then be protected and the product held during corrugation or crease until the cover means are removed. The release papers mentioned above have been found to be most useful herein.
