Description

[Technical Field]

[0001] The present invention relates to an absorbent article having an ear portion, particularly an elastic ear. [Background technology]

[0002] It has long been known that absorbent articles, such as conventional absorbent articles (e.g., diapers, adult incontinence products, feminine hygiene pads), offer the advantage of receiving and containing urine and / or other bodily discharges (e.g., feces, menstruation, mixtures of feces and urine, mixtures of menstruation and urine, etc.). For effective containment of bodily discharges, the article needs to fit snugly around the wearer's waist and legs.

[0003] Manufacturers often incorporate stretchable areas, such as stretch side panels (i.e., ears), within their garments to help achieve a snug fit. When worn, the elastic ears extend the garment around the wearer's buttocks and waist, securing the product during use while also allowing the wearer to move comfortably. Fastening systems are typically attached to the ears to further secure the product around the wearer. Elastic ears are typically a laminate of a surface material (such as nonwoven fabric) and an elastomer material.

[0004] It has been proposed to fabricate stretchable laminates using ultrasonic bonding. In this case, an elastomerized material is combined with a nonwoven fabric via ultrasonic bonding. After bonding, the nonwoven fabric forms pleats when the laminate is in a relaxed state. These laminates can produce highly stretchable selvages (depending on the level of stretchability imparted in the elastomerized material) while avoiding the use of glue and mechanical activation. Furthermore, unlike other forms of laminates, the elastomerized material does not need to extend across the entire width of the laminate. However, ultrasonically bonded selvages may lack the strength of other selvages. If the selvages lack the necessary strength during application, the selvages themselves may break, fasteners may detach from the selvages, and / or the selvages may detach from the rest of the article. Such defects can render the article unusable.

[0005] In addition to requiring adequate strength, manufacturers must balance numerous other factors when constructing earrings, including minimal stress concentration, desired force and stretch profile, breathability, shape, and aesthetic appeal. Furthermore, reducing costs and increasing efficiency during the production process are crucial to maintaining competitiveness in the field. [Overview of the project] [Problems that the invention aims to solve]

[0006] Therefore, there is a continuing need for elastic earlobes with desirable elasticity balanced with appropriate strength, particularly thermally (especially ultrasonically coupled) elastic earlobes with appropriate strength. Furthermore, there is a need for elastic earlobes with improved breathability while maintaining strength, appropriate stress profile, and / or other desirable properties. There is also a need for elastic earlobes that provide desired elasticity and / or force profile. Moreover, there is a need to provide desired properties and / or customizable profiles at minimal cost and with high efficiency. [Means for solving the problem]

[0007] In the embodiment, the absorbent article includes a chassis comprising a first waist region, a second waist region, a groin region positioned between the first and second waist regions, a top sheet, a back sheet, and an absorbent core positioned between the top sheet and the back sheet. The absorbent article also includes an ear positioned in one of the waist regions. The ear has a proximal side, a distal side, and an elasticized region. The ear includes a laminate having a first nonwoven fabric and a second nonwoven fabric, and an elastomeric material sandwiched between the first and second nonwoven fabrics in the elasticized region.

[0008] The laminate may include a first bonding region and a second bonding region. The first bonding region may include a first plurality of ultrasonic bonds having a first bonding density, and the second bonding region may include a second plurality of ultrasonic bonds having a second bonding density. The first bonding density may be higher than the second bonding density. In further embodiments, the first bonding region may have a first ultrasonic bonding pattern, and the second bonding region may have a second ultrasonic bonding pattern. The second ultrasonic bonding pattern may differ from the first ultrasonic bonding pattern by design elements, average bonding interval, pattern uniformity, bonding size, bonding shape, bonding orientation, total bonding area, total bonding range, total pattern shape, and / or combinations thereof.

[0009] In certain embodiments, the absorbent article includes a chassis comprising a first waist region, a second waist region, a groin region located between the first and second waist regions, and a top sheet, a back sheet, and an absorbent core located between the top sheet and the back sheet. The absorbent article also includes an ear located in either the first or second waist region, the ear being transversely stretchable. The ear has a proximal and distal side, an elastic region, and a laminate. The laminate includes a first nonwoven fabric and a second nonwoven fabric, and an elastomeric material sandwiched between the first and second nonwoven fabrics in the elastic region. The laminate also includes ultrasonic bonding of a first pattern. A fastening system may be bonded to the ear and may include a fastener pattern of ultrasonic bonding. The first pattern may coincide with the fastener pattern.

[0010] In a further embodiment, the absorbent article includes a first waist region, a second waist region, and a crotch region disposed between the first waist region and the second waist region, and a chassis including a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet. The absorbent article may also include ears disposed in one of the first waist region or the second waist region and having a laminate. The laminate may include a first nonwoven fabric and a second nonwoven fabric, an elastomeric material sandwiched between the first nonwoven fabric and the second nonwoven fabric in an elasticized region, and a plurality of ultrasonic bonds. Further, the laminate may include a first region and a second region, each region having an air permeability value of at least 1.0 m / m 2 / minute, and the air permeability ratio of the first region to the second region is at least 1.1.

[0012] definition The term "disposable" in relation to absorbent articles means that the absorbent article is not generally intended to be washed or otherwise restored or reused as an absorbent article (i.e., it is intended to be discarded after a single use, preferably recycled, composted, or disposed of in another environmentally friendly manner).

[0013] "Absorbent articles" refer to devices that absorb and contain bodily waste, and more specifically, devices that are in contact with or near the wearer's body and absorb and contain various types of bodily waste discharged from the body. Examples of absorbent articles include diapers, training pants, pull-on diapers (i.e., diapers with pre-formed waist and leg openings as shown in U.S. Patent No. 6,120,487), refastened diapers or diaper-type diapers, incontinence briefs and underwear, diaper holders and liners, panty liners and other feminine hygiene clothing, and absorbent inserts.

[0014] "Activation" is the mechanical deformation of a plastically stretchable material in which the stretchable material or a portion of the stretchable material permanently stretches in the activation direction in the XY plane of the material. For example, activation occurs when a web or a portion of a web is exposed to a stress that deforms the material beyond the strain that would cause plasticity, which may or may not involve complete mechanical breakage of the material or a portion of the material. Activation of a laminate containing an elastic material bonded to a plastically stretchable material typically results in the permanent deformation of the plastic material, while the elastic material substantially returns to its original dimensions. The activation process is disclosed in U.S. Patent Application Publication 2013 / 0082418, U.S. Patent No. 5,167,897, and U.S. Patent No. 5,993,432.

[0015] "Body-facing" and "clothing-facing" refer to the relative position of an element, its surface, or a group of elements, respectively. "Body-facing" means that the element or surface is closer to the wearer when worn than any other element or surface. "Clothing-facing" means that the element or surface is further away from the wearer when worn than any other element or surface (i.e., the element or surface is closer to the wearer's clothing that may be worn over a disposable absorbent article).

[0016] "Binding density" refers to the binding frequency and / or the total binding range.

[0017] "Bond frequency" refers to the 1 cm determined by the bond dimension test method specified herein. 2 This refers to the number of connections per unit.

[0018] "Total joint range" refers to the sum of the joint areas within a given region as determined by the joint dimension test method described herein.

[0019] "Longitudinal direction" refers to the direction that extends substantially perpendicularly from one waist edge of an article to the opposite waist edge, and substantially parallel to the article's maximum straight-line dimension. Directions within 45 degrees of the longitudinal direction are considered "longitudinal direction." "Longitudinal extension" refers to a component whose longitudinal dimension is greater than its lateral dimension. "Longitudinal stretchability" refers to a component that is stretchable in the longitudinal direction.

[0020] "Transverse" refers to a direction extending approximately perpendicular to the longitudinal direction from one longitudinal edge of an article to the opposite longitudinal edge. Directions within 45 degrees of the transverse direction are considered "transverse." "Extending transversely" refers to a component that has a transverse dimension greater than its longitudinal dimension. "Laterally stretchable" refers to a component that is stretchable when stretched transversely.

[0021] "Installed" means that an element is placed in a specific location or position.

[0022] "Joined" refers to a form in which an element is directly fixed to another element by directly attaching it to that element, and a form in which an element is indirectly fixed to another element by attaching it to one or more intermediate members, which in turn are attached to other elements.

[0023] A "film" refers to a sheet-like material in which the length and width of the material exceed its thickness (for example, 10 times, 50 times, or even 1000 times). Films are typically impermeable to liquids, but can be configured to be permeable.

[0024] "Laminate" means two or more materials bonded together by any preferred method known in the art (e.g., adhesive bonding, thermal bonding, or high-pressure bonding using unheated or heated patterned rolls).

[0025] "Nonwoven fabric" refers to a porous fibrous material produced from continuous (long) filaments (fibers) and / or discontinuous (short) filaments (fibers) by processes such as spun bonding, melt blowing, air laminating, carding, co-formation, and water entanglement. Nonwoven fabrics do not have a woven or knitted filament pattern. Nonwoven fabrics may be permeable to liquids or impermeable to liquids.

[0026] "Relaxed" means the state of an element, material, or component at rest, where there are virtually no external forces acting on it other than gravity.

[0027] "Elastic," "elastomerous," and "elastically stretchable" mean the ability of a material to stretch at least 100% under a given load without breaking or fracturing, according to the hysteresis tests described herein, and, when the load is removed, to exhibit at least 70% recovery in one of its directions (i.e., having a permanent set of less than 30%). Stretching, sometimes also called strain, strain rate, engineering strain, elongation ratio, or elongation, can be determined, as well as recovery and permanent set, according to the hysteresis tests described in more detail below. Materials that are not elastic are referred to as inelastic.

[0028] "Stretchability" means the ability to stretch or elongate by at least 50% without breaking or fracturing, according to step 5(a) of the hysteresis test specified herein (where the specified 100% strain is replaced with 50% strain).

[0029] As used herein, “design element” means a shape or combination of shapes that visually creates a distinct component, regardless of the size or orientation of the component. A design element may exist in one or more patterns. A design element may exist more than once within a single pattern. In a non-limiting example, the same design element may exist twice in a single pattern, with the second instance of the design element being smaller than the first instance. Those skilled in the art will recognize that other arrangements are also possible. A design element may include a mark. A design element and / or a combination of design elements may include letters, words, and / or graphics such as flowers, butterflies, hearts, or lettering. A design element may be formed from combinations that include one or more combined shapes. A design element and / or a combination of design elements may include directive markings that give guidance or instructions to a caregiver regarding the placement and / or fit of an article around the wearer.

[0030] As used herein, “pattern” means a decorative or distinctive design that is not necessarily repetitive or imitative, and includes, but is not limited to, clusters, geometric shapes, speckled, spiral, swirling, grid patterns, textures, helical, periodic, embossed, lace-like, mosaic patterns, star shapes, leaf shapes, blocks, pleated, concave, convex, mesh-like, tapered shapes, and combinations thereof. In some embodiments, a pattern includes one or more repeating design elements.

[0031] As used herein, “Mark” means any object, character representation, word, color, shape, or other indication that can be used to distinguish, identify, or represent a product manufacturer, retailer, wholesaler, and / or brand, including but not limited to trademarks, logos, emblems, symbols, designs, figures, fonts, lettering, coats of arms, or similar identifying marks.

[0032] Absorbent articles Figure 1 is a plan view of an exemplary, non-limiting embodiment of the absorbent article 10 of the present invention in a flat, non-shrinking state. The body-facing surface 115 of the absorbent article 10 faces an observer. The absorbent article 10 includes a longitudinal centerline 100 and a transverse centerline 110.

[0033] The absorbent article 10 comprises a chassis 20. The absorbent article 10 and chassis 20 are shown having a first waist region 14, a second waist region 18 opposite the first waist region 14, and a crotch region 16 located between the first waist region 14 and the second waist region 18. The waist regions 14 and 18 generally include portions of the absorbent article 10 that surround the wearer's waist when worn. The waist regions 14 and 18 may include elastic members 55 that form gathers around the wearer's waist to improve fit and containment. The crotch region 16 is the portion of the absorbent article 10 that generally lies between the wearer's legs when the absorbent article 10 is worn.

[0034] The outer periphery of the chassis 20 is defined by longitudinal edges 12 and waist edges (a first waist edge 13 in the first waist region 14 and a second waist edge 19 in the second waist region 18). The chassis 20 may have opposing longitudinal edges 12 oriented approximately parallel to the longitudinal centerline 100. However, for a better fit, the longitudinal edges 12 may be curved or angled so that, for example, an "hourglass" shaped article is produced when viewed in plan, as shown in Figure 1. The chassis 20 may also have opposing transverse edges 13, 19 (i.e., a first waist edge 13 and a second waist edge 19) oriented approximately parallel to the transverse centerline 110.

[0035] The chassis 20 may comprise a liquid-permeable top sheet 24, a back sheet 26, and an absorbent core 28 between the top sheet 24 and the back sheet 26. The top sheet 24 may be bonded to the core 28 and / or the back sheet 26. The back sheet 26 may be bonded to the core 28 and / or the top sheet 24. It will be understood that other structures, elements, or substrates may be positioned between the core 28 and the top sheet 24, and / or between the core 28 and the back sheet 26. In some embodiments, a capture-dispersion system 27 is positioned between the top sheet 26 and the absorbent core 28.

[0036] In certain embodiments, the chassis 20 includes the main structure of the absorbent article 10, along with other mechanisms added to form a composite absorbent article structure. The top sheet 24, back sheet 26, and absorbent core 28 can be assembled in various well-known configurations, but the configurations of absorbent articles are generally described in U.S. Patents 3,860,003, 5,151,092, 5,221,274, 5,554,145, 5,569,234, 5,580,411, and 6,004,306.

[0037] Top sheet: The top sheet 24 is generally part of the absorbent article 10 that may be at least partially in contact with or in close proximity to the wearer. Suitable top sheets 24 may include porous foams, mesh foams, perforated plastic films, or natural fibers (e.g., wood or cotton fibers), synthetic fibers (e.g., polyester or polypropylene fibers), or woven or nonwoven webs made of a combination of natural and synthetic fibers. The top sheet 24 is generally supple and soft to the wearer's skin and non-irritating. Generally, at least a portion of the top sheet 24 is liquid-permeable, allowing liquids to easily pass through its thickness. One useful top sheet 24 described herein is available from BBA Fiberweb (Brentwood, TN) under supplier code 055SLPV09U. The top sheet 24 may be perforated.

[0038] Any portion of the top sheet 24 may be coated with a lotion or skincare composition known in the art. Non-limiting examples of suitable lotions include those described in U.S. Patents 5,607,760, 5,609,587, 5,635,191, and 5,643,588. The top sheet 24 may be elasticized or shrunk, either entirely or partially, to create a void space between the top sheet 24 and the core 28. Exemplary structures including elasticized or shrunk top sheets are described in detail in U.S. Patents 4,892,536, 4,990,147, 5,037,416, and 5,269,775.

[0039] Absorbent core: The absorbent core 28 may include a wide variety of liquid absorbent materials commonly used in disposable diapers and other absorbent articles. Examples of suitable absorbent materials include crushed wood pulp, commonly referred to as air felt crepe cotton; meltblown polymers including coform; chemically stiffened, modified, or crosslinked cellulose fibers; tissue paper including tissue paper packaging and tissue paper laminates; absorbent foam; absorbent sponge; superabsorbent polymer; absorbent gelling material; or any other absorbent material or combination of materials. In one embodiment, at least a portion of the absorbent core may be substantially cellulose-free, contain less than 10% by weight of cellulose fibers, less than 5% by weight of cellulose fibers, less than 1% by weight of cellulose fibers, contain trace amounts of cellulose fibers, or contain no cellulose fibers. It will be understood that trace amounts of cellulose material do not substantially affect at least one of the thinness, flexibility, and absorbency of a substantially cellulose-free portion of the absorbent core. Among other advantages, when at least a portion of the absorbent core is substantially cellulose-free, this portion of the absorbent core is considered to be significantly thinner and more flexible than a similar absorbent core containing more than 10% by weight of cellulose fibers. The amount of absorbent material present in the absorbent core, such as absorbent particulate polymer material, may vary, but in certain embodiments, it may be present in the absorbent core in amounts of more than about 80% by weight of the absorbent core, or more than about 85% by weight of the absorbent core, or more than about 90% by weight of the absorbent core, or more than about 95% by weight of the core. In some embodiments, the absorbent core may comprise one or more channels 29, which are substantially free of absorbent particulate polymer material. The channels 29 may extend longitudinally or transversely. The absorbent core may further comprise two or more channels. The channels may be linear, curved, angled, or any functional combination thereof. In one non-limiting example, two channels are arranged symmetrically around a longitudinal axis.

[0040] Exemplary absorbent structures for use as absorbent core 28 are described in U.S. Patents Nos. 4,610,678, 4,673,402, 4,834,735, 4,888,231, 5,137,537, 5,147,345, 5,342,338, 5,260,345, 5,387,207, and 5,397,316, as well as U.S. Patent Applications Nos. 13 / 491,642 and 15 / 232,901.

[0041] Backseat: The backsheet 26 is generally positioned to be at least part of the surface 120 of the absorbent article 10 that faces clothing. The backsheet 26 may be designed to prevent soiling of items that may come into contact with the absorbent article 10, such as bed sheets and underwear, by excrement absorbed and contained within the absorbent article 10. In certain embodiments, the backsheet 26 is substantially impermeable to water. Suitable materials for the backsheet 26 include films manufactured by Tredegar Industries Inc. (Terre Haute, IN) and sold under trade names X15306, X10962, and X10964. Other suitable materials for the backsheet 26 include breathable materials that allow vapor to escape from the absorbent article 10 but prevent excrement from passing through the backsheet 26. Examples of breathable materials include composite materials such as woven webs, nonwoven webs, and film-coated nonwoven webs, as well as materials such as microporous films (manufactured by Mitsui Toatsu Co., Ltd. in Japan under the name ESPOIR NO, and by EXXON Chemical Co. (Bay City, TX) under the name EXXAIRE). A suitable breathable composite material containing polymer blends is available from Clopay Corporation (Cincinnati, OH) under the name HYTREL Blend P18-3097. Such breathable composite materials are described in detail in International Publication No. 95 / 16746 and U.S. Patent No. 5,865,823. Other breathable backsheets, including nonwoven webs and porosity-forming films, are described in U.S. Patent No. 5,571,096. An exemplary suitable backsheet is disclosed in U.S. Patent No. 6,107,537. Other suitable materials and / or manufacturing techniques may be used to provide a suitable backsheet 26, including, but not limited to, surface treatment, selection and processing of a particular film, and selection and processing of a particular filament.

[0042] The backsheet 26 may also consist of two or more layers. The backsheet 26 may comprise an outer cover and an inner layer. The outer cover may be made from a soft nonwoven material. The inner layer may be made from a substantially liquid-impermeable film such as a polymer film. The outer cover and the inner layer may be joined together by an adhesive or any other suitable material or method. A particularly suitable outer cover is available from Corovin GmbH (Peine, Germany) under supplier code A18AH0, and a particularly suitable inner layer is available from RKW Gronau GmbH (Gronau, Germany) under supplier code PGBR4WPR. While various backsheet configurations are envisioned herein, it will be apparent to those skilled in the art that various other changes and modifications are possible without departing from the spirit and scope of the invention.

[0043] Ears / fasteners: The absorbent article 10 may include one or more ears 30, for example, an anterior ear 32 located in a first waist region and / or a posterior ear 34 located in a second waist region. The ears 30 may be integral with the chassis or may be separate elements joined to the chassis 20 in chassis attachment joints 35 that can join one or more layers of the ears to the chassis. The ears 30 may be stretchable or elastic. The ear portions 30 may be formed from one or more nonwoven webs, woven webs, knitted fabrics, polymer films and elastomer films, perforated films, sponges, foams, scrims, or combinations and / or laminates thereof.

[0044] As shown in Figure 2, the ear may include a distal end 36 and a proximal edge 38. The distal end 36 is the free distal longitudinal edge of the ear. The proximal edge 38 is substantially opposite to the distal end 36. The proximal edge 38 is joined to or overlaps with the chassis when the ear is joined to the chassis, or is defined by a line extending from the longitudinal side 12 in the widest area of ​​the crotch region, and in the case of a one-piece ear, is the side parallel to the longitudinal centerline. The ear may further include a first transverse edge 40 and an opposing second transverse edge 42, and a transverse centerline 43 that is substantially parallel to the transverse centerline 110 of the article. The ear may further comprise a maximum width W extending between the distal end and the proximal edge, and a length Lv extending between the first and second transverse edges. In some examples, the length may vary in portion along the width of the ear, as shown in Figure 2. For example, the ear may have its maximum length along its proximal end 38 and may be tilted or otherwise varied such that the ear has its minimum length at its distal end 36. The ear further comprises a proximal side 380 encompassing the portion of the ear that extends approximately 5 mm lateral to the proximal edge 38 when measured parallel to the transverse centerline 43, and a distal side 360 ​​encompassing the portion of the ear that extends approximately 5 mm inward to the distal end when measured parallel to the transverse centerline 43.

[0045] In some embodiments, the selvage 30 may contain an elastomer, so the selvage is stretchable. In certain embodiments, the selvage 30 may be formed of a stretchable laminate such as a nonwoven / elastomerized material laminate or a nonwoven / elastomerized material / nonwoven laminate, which also results in the selvage being stretchable. The selvage 30 may be stretchable in the transverse direction. In some embodiments, the selvage is elastic when stretched in the transverse direction. In further embodiments, the selvage 30 may be stretched longer in the transverse direction than in the longitudinal direction. Alternatively, the selvage may be stretched more in the longitudinal direction than in the transverse direction.

[0046] In some embodiments, the selvage comprises a laminate of a first nonwoven fabric 300 and an elastomer layer 304. In the specific embodiments shown in Figures 3-4, the selvage comprises a first nonwoven fabric 300, a second nonwoven fabric 302, and an elastomer layer 304. The elastomer layer 304 may be sandwiched between the first and second nonwoven fabrics. Additional layers may be included (e.g., additional nonwoven fabrics, inelastic materials, elastic or stretchable materials, etc.).

[0047] Any suitable nonwoven fabric may be used in the selvage 30. Suitable nonwoven fabrics may include basis weights of at least about 8 gsm, or about 30 gsm or less, or about 22 gsm or less, or about 17 gsm or less, or about 10 gsm to about 22 gsm, and these ranges are listed in increments within this range. In non-limiting examples, the nonwoven fabric includes a meltblown layer. Further or alternatively, the nonwoven fabric may include a spunbond layer. In non-limiting examples, the nonwoven fabric includes two or more spunbond layers. In further non-limiting examples, one or more nonwoven fabrics may have an SMS configuration. Alternatively, one or more of the nonwoven fabrics in the selvage may not have a meltblown layer. Although the meltblown layer has been found to enhance bonding in the selvage where adhesive is required (in view of the meltblown layer inhibiting the diffusion of adhesive through the porous nonwoven structure), the meltblown layer is often insufficient in strength. In some embodiments, the nonwoven fabric essentially consists of spunbond layers. In some non-limiting examples, both the first and second nonwoven fabrics include at least two spunbond layers, or three or more spunbond layers.

[0048] If the selvage 30 contains more than one nonwoven fabric, the nonwoven fabrics may have the same or different basis weights. Similarly, the nonwoven fabrics may have the same (e.g., SMS) or different layer configurations. Furthermore, the nonwoven fabric in the selvage may include nonwoven fabrics of the same or different mechanisms in the backsheet, topsheet, leg gasket system, and / or waist mechanism.

[0049] The elastomeric layer 304 comprises one or more elastomeric materials that provide elasticity to at least a portion of the layer 304. Non-limiting examples of the elastomeric material include films (e.g., polyurethane films, films derived from rubber and / or other polymer materials), elastomeric coatings applied to another substrate (e.g., hot-melt elastomers, elastomeric adhesives, printed elastomers, or elastomers co-extruded onto another substrate), elastomeric nonwovens, scrims, and the like. The elastomeric material may be formed from any suitable known elastomer, including but not limited to styrene derivatives, polyesters, polyurethanes, polyetheramides, polyolefins, combinations thereof, or co-extruded VISTAMAXX®. Exemplary elastomers and / or elastomeric materials are disclosed in U.S. Patent Nos. 8,618,350, 6,410,129, 7,819,853, 8,795,809, 7,806,883, 6,677,258, and U.S. Patent Application Publication 2009 / 0258210.Commercially available elastomeric materials include KRATON (styrene-based block copolymer; available from Kraton Chemical Company (Houston, TX)), SEPTON (styrene-based block copolymer; available from Kuraray America, Inc. (New York, NY)), VECTOR (styrene-based block copolymer; available from TSRC Dexco Chemical Company (Houston, TX)), ESTANE (polyurethane; available from Lubrizol, Inc (Ohio)), PEBAX (polyether block amide; available from Arkema Chemicals (Philadelphia, PA)), HYTREL (polyester; available from DuPont (Wilmington, DE)), VISTAMAXX (homopolyolefin and random copolymer, and blends of random copolymers; available from EXXON Mobile (Spring, TX)), and VERSIFY (homopolyolefin and random copolymer, and blends of random copolymers; available from Dow Chemical Company (Midland, Michigan)).

[0050] In non-limiting examples, the elastomer layer 304 includes a film. The film may include a single layer or multiple layers. The film may be transversely stretchable or elastic when stretched transversely. The film may be pre-activated, for example, as disclosed in U.S. Patent No. 9,533,067. The elastomer layer may have a width Y, as shown, for example, in Figure 2. In some embodiments, Y is at least about 10 mm shorter than the width W of the ear 30. The elastomer layer may have the same longitudinal dimension as the ear 30 in addition to the width of the elastomer layer, or it may have a longitudinal dimension shorter than the longitudinal length of the ear at any point in addition to the width of the elastomer layer. In some embodiments, the elastomer layer may have a basis weight of about 5 to about 150 gsm, or about 10 to about 100 gsm, or less than about 150 gsm, and each range is enumerated in 5 gsm increments within this range.

[0051] As shown in Figure 2, the ear 30 may include an elastic region 306. The elastic region 306 is generally defined by the periphery of the elastomer material 304. In the elastic region, the ear is elastically stretchable. In some embodiments, the area of ​​the elastic region includes at least about 20%, or about 30% to about 100%, or about 80% or less, of the total area of ​​the ear, and these ranges are enumerated in 5% increments within this range. In further embodiments, Y (i.e., the maximum width of the elastomer layer) includes at least about 20%, or about 25% to about 100%, or about 35% to about 85%, or about 80% or less, of the total width W of the ear, and these ranges are enumerated in 5% increments within this range.

[0052] The ear may further include one or more inelastic regions. In a particular embodiment, the ear 30 includes a first inelastic region 308 which extends laterally outward from the proximal edge 38 and is adjacent to the elastic region 306 at the first elastomeric material edge 307. The ear may further include a second inelastic region 310 which may extend laterally inward from the proximal edge 36 and be adjacent to the elastic region 306 at the second elastomeric material edge 309. The first and second inelastic regions may be made of the same material or of different materials.

[0053] In certain embodiments, the selvage 30 includes a gathered laminate 44 in which one layer of the layers deforms more than the remaining layers during lamination. Thus, the low-stretch layers (i.e., nonwoven fabrics 300, 302) form gathers when the laminate 44 is relaxed. In some embodiments, at least a portion of the elastomer layer deforms while the nonwoven fabric is relaxed during lamination. The elastomer layer can be stretched in one or more directions. Then, when the subsequently formed laminate 44 is relaxed, folds are formed within the nonwoven fabric layers. In non-limiting examples, the elastomer layer is stretched in a direction corresponding to the transverse direction of the article. In other words, when the selvage is joined to the chassis after lamination, the selvage laminate is oriented so that the selvage is stretchable in the transverse direction of the article (i.e., the selvage is stretchable in the transverse direction). In further non-limiting examples, the selvage is also stretchable in the longitudinal direction.

[0054] In some examples, the edges of the first and / or second elastomeric material do not elongate or elongate by less than 10% during lamination, providing one or more non-elongated regions 37, 39 along the edges. In some embodiments, the non-elongated regions have a maximum lateral width of about 2 mm to about 12 mm, and are enumerated in 1 mm increments within this range. The maximum lateral width of the non-elongated regions may be about 40% or less of the width Y of the elastomeric layer. In further embodiments, the non-elongated regions have a longitudinal length L of the edge over which regions 37, 39 are located. v It can be stretched by at least about 80%. The length and / or width of the non-stretched regions may be different. If there are multiple non-stretched regions, they may have the same or different dimensions. For example, Figure 2 shows two non-stretched regions 37, 39 of different lengths (i.e., different from each other), where each region 37, 39 has a different length across its respective width (Z1, Z2).

[0055] The absorbent article 10 may also include a fastening system 48. When fastened, the fastening system 48 connects the first waist region 16 and the rear waist region 18, resulting in a waist circumference that can surround the wearer while the absorbent article 10 is being worn. The fastening system 48 may comprise fastening elements 50 such as tape tabs, hook-loop fastening components, interlocking fasteners such as tabs and slots, buckles, buttons, snaps, and / or hermaphroditic fastening components, but any other known fastening means are generally acceptable. The absorbent article may further include a landing zone into which the fastening elements can engage and / or a release tape that protects the fastening elements from injury before use. Several exemplary surface fastening systems are disclosed in U.S. Patents No. 3,848,594, No. 4,662,875, No. 4,846,815, No. 4,894,060, No. 4,946,527, No. 5,151,092 and No. 5,221,274. An exemplary interlocking fastening system is disclosed in U.S. Patent No. 6,432,098. In some embodiments, the fastening system 48 and / or element 50 is foldable.

[0056] The fastening system 48 can be joined to any suitable part of the article 10 by any suitable means. In some embodiments, the fastening system is joined to the ear 30 in a fastener attachment joint 52, for example, as shown in Figures 3-4. The fastening system may be joined to the ear between layers, as shown in Figure 4. The fastening system may be joined to the ear or the outer surface of the ear, for example, as shown in Figure 3. The fastening system may be joined to the body-facing surface of the ear or to the garment-facing surface. In a non-limiting example, the fastening system 48 and / or fastening element 50 are ultrasonically coupled to the ear 30. The fastening attachment joint 52 has a maximum length measured parallel to the longitudinal centerline. The maximum length may be about 30 mm or less, or about 28 mm or less, or about 20 mm to about 35 mm, and these ranges are listed in 1 mm increments within the range. The fastening attachment joint may join the fastening system to one or more layers of the ear, as shown in Figures 3-4.

[0057] The fastening system 48 may be joined to the ear at the distal end 360. The fastening system may be located within a second inelastic region 310 (see Figure 3). In a further embodiment, the fastening system 48 is joined in the elastic region 306 of the ear (see Figure 4). The inventors have found that joining the fastening system to the ear in the elastic region 306 improves the overall strength of the ear / fastening system combination during use and / or application. Although not bound by theory, since intact nonwoven fabrics are resistant to the stretching of the elastomeric layer, breakage of the ear formed from the ultrasonically bonded laminate first occurs in the inelastic region at the distal end 360, and therefore, joining the fastening system within the elastic region 306 is thought to reduce stress on the inelastic region of the ear. In some embodiments, the fastening system 48 is joined in the elastic region such that it overlaps with the elastic region by a maximum lateral overlap distance D, as shown in Figure 4. In certain non-limiting examples, D may be approximately 0.05% to 5% or 1% to 5% of Y (i.e., the maximum width of the elastic region), and each range is listed in 0.02% increments within that range.

[0058] In certain embodiments, the ear has an air permeability of at least about 1 m 3 / m 2 / min, or about 1 m 3 / m 2 / min to about 125 m 3 / m 2 / min, or about 2 m 3 / m 2 / min to about 50 m 3 / m 2 / min and may list each 1 m 3 / m 2 increments within the range for each range.

[0059] In some embodiments, the ear may not have an adhesive. In some non-limiting examples, the ear includes only adhesive bonds to the chassis attachment bond 35 and / or the fastener attachment bond 52.

[0060] The layers of the laminate can be joined by one or more thermal bonds 46, such as ultrasonic bond 46a, as shown in FIGS. 5-6 for example. The ultrasonic bond can join the nonwoven layer through an elastomeric layer. The thermally bonded laminate can be formed by the processes and / or equipment disclosed in U.S. Patent Application No. 62 / 419,515, assigned to the same assignee as the present application filed as Attorney Docket No. 14562P. Similarly, the chassis attachment bond 35 can include a thermal bond that may consist of an ultrasonic bond. The chassis attachment bond 35 can join one or more layers of the ear to the chassis as shown in FIGS. 3-4. The fastener attachment bond 52 can also include a thermal bond that may consist of an ultrasonic bond. The bonds can be arranged in regions and / or patterns and can be used to impart special properties to the regions and / or patterns.

[0061] Returning to Figures 5-6, in the embodiments, the ear includes a first bonding region 400. The first bonding region may include a thermal bond 46 within a first plurality of bonds 402. In some embodiments, the thermal bond consists of an ultrasonic bond 46a located within the first plurality of ultrasonic bonds 402. For the purposes of this disclosure, the bonding region may be described as including an ultrasonic bond, but other forms of thermal bonding are also within the scope of this disclosure.

[0062] Figure 5 shows a first bonding region outlined to indicate the periphery (i.e., shape of the region) of the region created by the first plurality of ultrasonic couplings 402. The first plurality of ultrasonic couplings 402 can bond one or more layers of the ear laminate. Furthermore, or alternatively, the first plurality of ultrasonic couplings 402 can bond two or more layers of the ear to the fastening system 48 or chassis 20. The couplings 46 within the first plurality of 402 can bond the same layer of the ear or different layers of the ear. The first bonding region may extend longitudinally or transversely. The first bonding region may extend to the entire length of the ear in which the first bonding region exists (as shown in Figure 6), or to a shorter length than the entire length of the ear in which the bonding region exists (see Figure 5). In some embodiments, the first bonding region may extend about 20% to about 80%, or less than about 80%, or less than about 75%, or less than about 60%, shorter than the total length of the ear in which the first bonding region exists, and these ranges are enumerated in 10% increments within the range. Thus, at a given lateral distance from the distal end of the ear, the ear may include different bonding regions and / or bonding regions at different longitudinal positions. In other words, the bonding and the properties resulting from the bonding as described herein may vary longitudinally. Furthermore or alternatively, the first bonding region may be aligned with the ear or fastener mechanism, or a specific position of the mechanism. In non-limiting examples, the first bonding region is aligned such that a portion of the periphery of the first bonding region aligns with the waist edge, the edge of the fastening system, and / or a portion of the fastening system.

[0063] Furthermore, as shown in Figure 6, the first set of multiple connections 402 may be arranged in pattern 404. Alternatively, the first set of multiple connections 402 may be arranged so as not to form a recognizable pattern, as shown in Figure 5.

[0064] The ear may further comprise a second bonding region 406, which includes a second plurality of thermal bonds 408. The second plurality of thermal bonds may comprise a second plurality of ultrasonic bonds 408. The second bonding region 406 may be adjacent to the first bonding region 400 or spaced apart from the first bonding region 400. The second plurality of ultrasonic bonds 408 may bond two or more layers of the ear's laminate. Furthermore, the second plurality of ultrasonic bonds 408 may bond one or more layers of the ear to the fastening system 48 or chassis 20. The second plurality of bonds 408 may bond the same or different layers as the first plurality. Bonds 46 within the second plurality 408 may bond the same or different layers. The second bonding region may extend longitudinally or transversely. The second bonding region may extend to the entire length of the ear in which the second region exists (as shown in Figure 6), or it may extend to a shorter length than the entire length of the ear in which the second region exists (see Figure 5). In some embodiments, the second bonding region may extend to about 20% to about 80%, or less than about 80%, or less than about 75%, or less than about 60%, shorter than the entire length of the ear in which the second region exists, and these ranges are enumerated in 10% increments within the range. Thus, at a given lateral distance from the distal end of the ear, the ear may include different bonding regions and / or bonding regions at different longitudinal positions. In other words, the bonding and the properties resulting from the bonding as described herein may vary in the longitudinal direction. Furthermore or alternatively, the second bonding region may be aligned with the mechanism of the ear or fastening system, or a specific position of the mechanism. In non-limiting examples, the second bonding region is aligned such that a portion of the periphery of the second bonding region aligns with the waist edge, the edge of the fastening system, and / or a portion of the fastening system.

[0065] Furthermore, as shown in Figure 6, the second set of bonds 408 may be arranged in the second pattern 410. In other embodiments, the second set of bonds 410 may be arranged in the first pattern. In other words, the two regions may contain substantially the same pattern. Alternatively, the second set of bonds 408 may be arranged so as not to form a recognizable pattern, as shown in Figure 5.

[0066] Similarly, the ear may have additional bonding regions having thermal bonds that can be arranged in a pattern. For example, the ear may include a third bonding region 412 having a third plurality of thermal bonds 414 that can be arranged in a third pattern 416, for example, as shown in Figure 6. The additional region may have the same properties as the first or second bonding region, or it may have different properties. The additional bonding region, such as the third bonding region, may extend laterally or longitudinally, and may extend along the entire longitudinal length of the ear in which the additional bonding region exists, or may extend to a shorter length than the entire length of the ear in which the additional bonding region exists. In some embodiments, the additional bonding region may extend to about 20% to about 80%, or less than about 80%, or less than about 75%, or less than about 60%, shorter than the entire length of the ear in which the additional bonding region exists, and these ranges are enumerated in 10% increments within the range. Thus, at a given lateral distance from the distal end of the ear, the ear may include different bonding regions and / or bonding regions at different longitudinal positions. In other words, the bond and the properties resulting from the bond as described herein may vary in the longitudinal direction. Furthermore or alternatively, additional bond regions may be aligned with the ear or fastener mechanism, or specific locations of the mechanism. In a non-limiting example, the additional bond region may be aligned such that a portion of the periphery of the additional bond region aligns with the waist edge, the edge of the fastening system, and / or a portion of the fastening system.

[0067] The first plurality of bonds 402 may have a first bond density. The second plurality of bonds 408 may have a second bond density different from the first bond density. In some embodiments, the first and second bond densities differ by the bond frequency determined by the bond measurement test method described herein. In further embodiments, the first and second bond densities differ by the overall bond range of each region determined by the bond measurement test method described herein. As a non-limiting example, the first bond region may have a higher bond frequency than the second bond region, as schematically shown in Figure 5, and / or the first bond region may have a larger overall bond range than the second bond region. The first bond density may be at least 5% higher than the second bond density (i.e., 5% higher bond frequency and / or 5% higher overall bond area), or at least 10% higher than the second bond density, or about 10% to about 90% higher, or about 15% to about 85% higher, or about 25% to about 75% higher, listed in 10% increments within each range. In some embodiments, the first bond region has a higher bond frequency than the second bond region. Furthermore or alternatively, the first bond region may have a higher overall bond area than the second bond region. By providing a higher bond density in a given bond region, it is possible to increase the bond strength, reduce stress concentration, increase the modulus of elasticity, enable different levels of extension, and / or increase breathability in the bond region. Similarly, the ear may have a third bond density in a third bond region 412, which may be the same as the first bond region or the same as the second bond region. Alternatively, the third bond density may be larger than the second bond region or differ in other respects from the first and / or second bond densities. It is also conceivable that two or more bond densities may be the same. In some embodiments, the first and second bond densities are the same, but these bond regions differ in design elements; the average spacing between bonds in the region; the size, shape, and / or orientation of bonds in the region; the total bond area; and / or the overall shape of the bond region (i.e., the periphery of the region).

[0068] The first bonding region 400 may be positioned on the proximal side 380 of the ear such that, when measured parallel to the transverse centerline 43, the minimum distance between the nearest bond in the first plurality and the proximal edge 38 of the ear is 5 mm or less. In some embodiments, the chassis mounting bond 35 is positioned at least partially within the bonding region 400. In further non-limiting examples, the first bonding region 400 extends longitudinally and is positioned at least partially on the proximal side 380. By positioning the first bonding region with a higher bonding density on the proximal side, the strength of the ear laminate in the mounting region can be increased. This increased laminate strength can improve the transmission of forces from the chassis mounting bond to the ear, reducing stress on the bonding site and / or stress concentration in the laminate. Furthermore or alternatively, by having the first bonding region of the first bonding pattern positioned on the proximal side 38, the ear can have a visual characteristic specific to that region. As a non-limiting example, pattern 404 may include markings, indicators, garment-like patterns, and / or other design elements that distinguish the proximal side from the rest of the ear, as shown in Figure 6.

[0069] In certain embodiments, the bonding regions (e.g., a first bonding region or a third bonding region) may be positioned on the distal side 36 of the ear such that, when measured parallel to the transverse centerline 43, the minimum distance between the closest bonding region in the first group and the distal edge of the ear is 5 mm or less. In non-limiting examples, the fastener attachment bonding region 52 is at least partially positioned within the bonding region (shown as a third bonding region 412 in Figure 6). By positioning bonding regions with a higher bonding density on the distal side, the strength of the ear laminate in the attachment region can be increased, and this increased strength of the laminate can improve the transmission of force from the fastener attachment bonding to the fastener, thereby reducing stress on the bonding site and / or stress concentration in the laminate. Furthermore or alternatively, by having bonding regions of a bonding pattern positioned on the distal side 360, the ear can have visual characteristics specific to that region. As a non-limiting example, pattern 416 may include markings, indicators, garment-like patterns, and / or other design elements that distinguish the distal side from the rest of the ear, as shown in Figure 6.

[0070] A first bond region may have a first pattern 404, and a second bond region may have a second pattern 410. The first and second bond patterns may differ in various ways, including but not limited to: design elements; average spacing between bonds within the pattern; uniformity within the pattern; size, shape and / or orientation of bonds within the pattern; total bond area within the pattern; and / or overall pattern shape (i.e., the periphery of the pattern). In embodiments including a third bond region, the third pattern 416 may similarly differ from the first and / or second bond patterns. Bond regions may have different bond densities, and two or more bond regions may have the same bond density but different bond patterns. In a non-limiting example, the first and second bonding regions have the same bonding density, and the first and second bonding patterns differ by design elements; the average spacing between bonds within the pattern; uniformity within the pattern; size, shape, and / or orientation of bonds within the pattern; total bonding area within the pattern; and / or the overall pattern shape (i.e., the periphery of the pattern).

[0071] In some embodiments, the second pattern is at least partially located within the elasticized region 306. In some non-limiting examples, the second bonding pattern 410 has bonding spacing in pattern 410 that, on average, is greater than the bonding spacing in the first bonding pattern 404. Larger spacing can emphasize certain characteristics of the ear. For example, larger bonding spacing in the elasticized region 306 can emphasize the folds that occur in the elasticized region. Indeed, wider lateral spacing between bonding can form fewer but larger folds in the gathered laminate 44. In further embodiments, the second bonding pattern 410 may include graphics.

[0072] Furthermore, or alternatively, as shown in Figure 7, bond regions (e.g., a first bond region or a third bond region) can be used to highlight and frame the elasticized regions, indicating to the end user where the elasticized regions are located. This can be achieved, for example, by making the spacing between bonds closer, increasing the bond density, or shifting the pattern and / or graphics in regions adjacent to and / or non-stretched regions of the elasticized regions.

[0073] In certain embodiments, the first bonding region 400 may at least partially overlap with at least one non-stretched region 37, 39. The first bonding region may overlap with the non-stretched region in at least a portion of it, over the entire length of the portion in the longitudinal direction, or for a shorter period than the entire length. Increasing the bonding density in the non-stretched region can reduce stress concentration in the elastomeric material that occurs during stretching, making it possible to use lower basis weight elastomeric material, weaker elastomeric material, and / or less elastomeric material while maintaining sufficient lamination strength for article 10. The increased bonding density can also reduce the risk of film tearing. In some embodiments, the non-stretched region may be located within the first bonding region and have a maximum width Z1 of about 2 to about 6 mm or about 2 to about 4 mm, listed for each range in 1 mm increments within the range. In some embodiments, an additional non-extended region 39 is located in the third bonding region 412, which may have a higher bonding density than the first and / or second bonding densities.

[0074] In certain embodiments, as shown in Figure 8, the orientation of one or more bonds in the first plurality 402 may differ from the orientation of one or more bonds in the second plurality 408. As a non-limiting example, most of the bonds in the first plurality may be oriented at 1 to 90° with respect to the ear centerline 43, and most of the bonds in the second plurality may be oriented at 91 to 180° with respect to the ear centerline 43, or vice versa. Any functional combination of different orientations is conceivable. Similarly, the bonds in the third plurality may have a different orientation from those in the first and / or second plurality.

[0075] In the embodiment, the first bonding region and the second bonding region are determined by the air permeability test method specified herein, with a minimum of 1 m 3 / m 2 / min, or approximately 1m 3 / m 2 / min ~ approx. 125m 3 / m 2 The first bonding region has an air permeability value of / min, and the first bonding region contains a greater air permeability value than the second bonding region. In non-limiting examples, the air permeability ratio of the first bonding region to the second bonding region is at least 1.1. Furthermore or alternatively, the bonding regions may differ in modulus of elasticity, extensibility, strength, and / or appearance. In some non-limiting examples, the modulus of elasticity in the first bonding region is greater than that in the second bonding region.

[0076] Any of the bonding regions may extend in the direction of elongation within the ear. In this way, bonding regions can be used to improve the elongation profile of the ear. In some embodiments, one or more bonding regions extend laterally. In further embodiments, the bonding region has a shape determined by the periphery created by the outermost bonding in that region. In non-limiting examples, one or more bonding regions 400, 406, 412 may have a substantially trapezoidal shape, as shown in Figure 9. By forming the bonding regions in a trapezoidal shape, the elastic modulus of the ear can be customized to create a better fit profile for the wearer. Furthermore, bonding regions and / or patterns can be used to create force, elongation, elastic modulus profiles or other features described in U.S. Patent Applications Nos. 8,858,523, 8,062,278, 8,491,557, 8,690,852, and 9,211,221.

[0077] Returning to Figure 6, fastener 48 may include a thermal coupling, which may consist of an ultrasonic coupling. The ultrasonic coupling may be located within one or more fastener coupling regions 480, 482, 484, any of which may have coupling patterns 486, 488, 490. In some non-limiting examples, fastener coupling pattern 480 may match one or more coupling patterns in the ear. For example, fastener coupling pattern 480 may match a first coupling pattern 404 or a second coupling pattern 410 as shown in Figure 6. Matching does not require the patterns to be exactly the same; the patterns may contain substantially similar design elements, which may be rotated, inverted, reduced in size, increased in size, and / or have their aspect ratios changed, and still be considered to match. In some non-limiting examples, fastener coupling pattern 484 may differ from one or more coupling patterns in the ear. The pattern may differ in various ways, including but not limited to: design elements; average spacing between bonds within the pattern; uniformity within the pattern; size, shape, and / or orientation of bonds within the pattern; total bond area within the pattern; and / or overall pattern shape (i.e., pattern periphery). The fastening system may overlap with the distal side of the ear to form an overlapping region 492, as shown in Figure 6. In some embodiments, the overlapping region includes a bonded region 484. The bonded region 484 may have a pattern 490 that differs from any of the bonded patterns in the ear (404, 410, 416) and / or any of the bonded patterns in the fastening system (486, 488). Alternatively, the overlapping region 492 may include a bonded region 484 having a pattern 490 that matches any of the remaining bonded patterns in the ear and / or the fastening system. The fastening system is at least 1 m 3 / m 2 It may have an air permeability value of / min. In a non-limiting example, the air permeability ratio between the binding regions 400, 406, 412 in the ear and the fastener binding region 480 is at least 1.1. The fastener binding region 480 may be positioned on the fastening system so as not to overlap with the ear laminate.

[0078] Furthermore, the ear may include one or more bonds formed by other bonding techniques, including but not limited to adhesive bonding, mechanical bonding, pressure bonding, thermal bonding, and functional combinations thereof. These additional bonds may be used in conjunction with one or more ultrasonic bonding regions and may be used in separate regions of the ear. In some embodiments, at least a portion of the ear is activated by mechanical activation.

[0079] Leg gasket system Returning to Figure 1, the absorbent article 10 may include a leg gasket system 70 attached to a chassis 20, the chassis may include one or more cuffs 71. The leg gasket system may include a pair of barrier leg cuffs 72. Each barrier leg cuff may be formed from a single piece of material bonded to the absorbent article, so as to extend upward from the wearer-facing surface of the absorbent article and provide improved containment of liquids and other excretions near the junction of the wearer's torso and legs. The barrier leg cuff is bounded by a proximal edge bonded directly or indirectly to the top sheet 24 and / or back sheet 26 and a free edge 75 intended to contact the wearer's skin and form a seal with the wearer's skin. In some embodiments, the free edge 75 includes a folded edge. The barrier leg cuffs 72 extend at least partially between the front waist edge 13 and the rear waist edge 19 of the absorbent article on both sides of the longitudinal centerline 100 and are at least present within the crotch area. The barrier leg cuff may be joined to the article chassis at its proximal edge by bonding, which may be carried out by gluing, melt bonding, or a combination of other suitable bonding processes.

[0080] The barrier leg cuff may be integrated with the top sheet 24 or back sheet 26, or it may be a separate material bonded to the chassis of the article. Each barrier leg cuff 72 may have one, two, or more elastic elements 55 adjacent to the free edge 75 to provide better sealing.

[0081] In addition to the barrier leg cuff 72, the article may include a gasket cuff 76 bonded to the chassis of the absorbent article, particularly the top sheet 24 and / or back sheet 26, and positioned outside the barrier leg cuff 72. The gasket cuff 76 can provide a better seal around the wearer's thigh. The gasket cuff may have a proximal edge and a free end edge 77. The free end edge 77 may have a folded edge. Each gasket cuff may have one or more elastic elements 55 in the chassis of the absorbent article between the top sheet 24 and the back sheet 26 in the leg opening region. The barrier leg cuff and / or gasket cuff, in whole or in part, may be treated with a lotion or another skincare composition.

[0082] In a further embodiment, the leg gasket system includes a barrier leg cuff integrated with a gasket cuff.

[0083] Suitable leg gasket systems, which may be part of an absorbent article, are disclosed in U.S. Patent Applications No. 62 / 134,622, No. 14 / 077,708, and U.S. Patents No. 8,939,957, No. 3,860,003, No. 7,435,243, and No. 8,062,279.

[0084] Elastic waist mechanism As shown in Figure 1, the absorbent article 10 may include at least one elastic waist mechanism 80 that helps provide improved fit and containment. The elastic waist mechanism 80 is generally intended to stretch and contract to dynamically fit the wearer's waist. The elastic waist mechanism includes a waist band, a waist cuff having a pocket formed from a portion of the waist mechanism 80 that is detached from the chassis 20, and a waist panel designed to fit snugly around the wearer's abdomen. Non-limiting examples of elastic waist mechanisms are disclosed in U.S. Patent Applications No. 13 / 490,543, No. 14 / 533,472, and No. 62 / 134,622. The waist mechanism 80 may be bonded to the chassis 20 in a first waist region 14 and / or a second waist region 16. The waist mechanism may be used in conjunction with ears 30 to provide desirable stretch and flexibility for a proper fit of the article to the wearer.

[0085] package The absorbent articles 10 of this disclosure may be placed in a package. The package may include a polymer film and / or other materials. Patterns and / or indicators relating to the properties of the absorbent articles may be formed, printed, positioned, and / or placed on the outer portion of the package.

[0089] Test method Joint Dimension Test Method Bond dimensional testing is used to measure the bond density of laminates in various bond regions. For the purposes of this method, a bond is an intentional joint of two or more layers, and is a deformed region that occurs during the bonding process (e.g., reduced caliper at the bond site). In some cases, a deformed region may be recognized as containing one or more openings.

[0090] Sample collection 1. Uniform pattern region: To measure the bonding density of a bonding region with a uniform pattern, measure 1 cm². 2Cut out a square sample of area 1 cm from the patterned bonding region of the laminate. If different, care must be taken to avoid collecting sample from adjacent regions. 2 If the square sample collection size is larger than the patterning area, 1 cm 2 A rectangular sample with an area of ​​1 cm² was collected, and the shorter dimension of the patterned area formed one side of the rectangle, while the other side formed the area of ​​the rectangle with an area of ​​1 cm². 2 It will be selected to be so. 2. Other regions: To measure the binding density of binding regions that do not have a uniform pattern, identify multiple target bonds and draw the peripheral contour obtained as shown in Figure 5. Collect the sample by cutting along the periphery. 3. The ear may be segmented into three longitudinally extending regions to such an extent that the connection region is indistinguishable: the first region has a width corresponding to the maximum width between the proximal edge of the ear and the edge of the chassis connection closest to the distal edge of the ear. The second region has a width corresponding to the maximum width between the distal edge and the edge of the fastener attachment connection closest to the proximal edge of the ear. The third region has a width extending between the first and second regions. Each region extends longitudinally with respect to the length of the ear within its respective region, and its length may change in the same way that the length of the ear changes within its respective region.

[0091] Bonding frequency: Bonding density based on bonding frequency is calculated by counting the number of bonds in the sample and dividing the number of bonds by the area of ​​the sample. Partial bonds are counted as a proportion equal to the ratio of the area of ​​bonds contained in the sample to the area of ​​all bonds (i.e., bonds before the sample was cut) to the extent that partial bonds are formed within the sample region by sample collection. Bond dimensions are measured with an accuracy of 0.01 mm using a microscope and / or imaging software. Using the dimensions of each bond, the bond area is calculated according to a mathematical area formula for a given bond shape. Using a total of five samples, the average bond density based on bonding frequency is calculated.

[0092] Total Bonding Range: The bonding density based on the total bonding range is calculated by summing the bonding areas of each bond in the sample and dividing it by the sample area. Bond dimensions are measured with an accuracy of 0.01 mm using a microscope and / or imaging software. The bonding area is calculated using the dimensions of each bond according to a mathematical area formula for a given bond shape. The area of ​​partial bonds within the sample is also measured. The total bonding area of ​​the sample is calculated by adding up all bonding areas within the sample, and then the total bonding area is divided by the sample area to obtain the total bonding range. The total bonding range based on bonding frequency is calculated using a total of five samples.

[0093] Hysteresis testing methods Hysteresis testing can be used for various specified strain values. Hysteresis testing utilizes a commercially available tensile testing machine connected to a computer (e.g., Instron Engineering Corp. (Canton, MA), SINTECH-MTS Systems Corporation (Eden Prairie, MN), or equivalent). The computer is used to control the test speed and other test parameters, and to collect, calculate, and report data. The test is performed under laboratory conditions of 23°C ± 2°C and 50% ± 2% humidity. The sample is conditioned 24 hours prior to the test.

[0094] The sample is cut to dimensions of 10 mm in the intended elongation direction of the ear and 25.4 mm in the direction perpendicular to the intended elongation direction of the ear. The sample is collected from either the inelastic or elastic region.

[0095] Test protocol 1. Select an appropriate grip and load cell. The grip must have a flat surface and be wide enough to hold the sample along its entire width. The grip must also provide sufficient force and a suitable surface to ensure the sample does not slip during testing. The load cell should be selected so that the tensile response from the sample being tested is 25% to 75% of the load cell capacity used. 2. Calibrate the testing machine according to the manufacturer's instructions. 3. Set the distance between the grips (gauge length) to 7mm. 4. Place the sample on the grip plane so that a uniform width is aligned perpendicular to the gauge length. Secure the sample with the upper grip, allowing the sample to hang loosely, then close the lower grip. Set the preloaded slack to 5 grams / force. This means that data acquisition will begin when the slack is removed with a force of 5 grams-force (at a constant crosshead speed of 13 mm / min). Strain is measured over the adjusted gauge length (l ini The calculation is based on the following, but the adjusted gauge length is the length of the sample between the grips of a tensile testing machine with a force of 5 grams force. This adjusted gauge length is taken as the initial sample length, which corresponds to 0% strain. The strain rate at any point in the test is defined as the change in length relative to the adjusted gauge length, which is obtained by dividing by the adjusted gauge length and multiplying by 100. 5(a) First period loading: Pull the sample to 100% strain at a constant crosshead speed of 70 mm / min. The elongated sample length between the grips is l max I will report it as such. 5(b) First period load release: Hold the sample at 100% strain for 30 seconds, then move the crosshead to its starting position (0% strain or initial sample length, l) at a constant crosshead speed of 70 mm / min. ini Return to the original position. Hold the sample in a relaxed state for 1 minute. 5(c) Second period loading: The sample is pulled to 100% strain at a constant crosshead speed of 70 mm / min. 5(d) Second period load release: Next, the sample is held at 100% strain for 30 seconds, and then the crosshead is returned to its starting position (i.e., 0% strain) at a constant crosshead speed of 70 mm / min.

[0096] The computer data system records the force applied to the sample during the test as a function of the applied strain. From the resulting data, the following quantities are reported: i. Preloaded slack in units of 0.001 mm, 5 grams (l) ini The sample length between grips in ). ii. 100% distortion (l) in units of 0.001 mm max Sample length between grips in the first cycle of ). iii. 7 grams (l) in units of 0.001 mm ext The sample length between grips at the second cycle load force. iv. In units of 0.01%, (l ext -l ini ) / (l max -l ini Permanent strain %) is defined as ) × 100%.

[0097] The test is repeated with six separate samples, and the mean and standard deviation are reported.

[0098] Air permeability test method The air permeability of a perforated laminate or substrate (e.g., film, nonwoven fabric, or component of an article) is determined by measuring the flow velocity of standard conditioned air passing through a sample driven by a specified pressure drop. This test is particularly suitable for materials with relatively high gas permeability, such as nonwoven fabrics and perforated laminates. ASTM D737 was used with the following modifications.

[0099] Use a TexTest FX3300 instrument or equivalent available from Textest AG (Switzerland) or Advanced Testing Instruments ATI (Spartanburg SC, USA). Follow the procedures described in the operating instructions of the TEXTEST FX3300 air permeability tester manual, under Airtightness Testing and Functional and Calibration Checks. If using a different instrument, follow similar provisions regarding airtightness and calibration as specified in the manufacturer's instructions.

[0100] The sample is tested while it is in a relaxed state.

[0101] The test pressure drop was set to 500 Pascals, and 1 cm 2Use an area test head (FX3300-5 model) or equivalent. Record the results with three significant figures. Calculate the average of the five samples and determine the air permeability value (m²). 3 / m 2 Report as ( / minute).

[0102] To determine the air permeability ratio between two regions, divide the air permeability value of region (i) by the air permeability value of the comparison region (ii): BV i / BV ii = permeability ratio.

[0103] Bag stack height test The stacking height inside the bag of absorbent material packaging is determined as follows:

[0104] device A thickness tester is used that includes a flat, rigid horizontal sliding plate. The thickness tester is configured such that the horizontal sliding plate moves freely in the vertical direction, while the horizontal sliding plate is always maintained in a horizontal orientation directly above a flat, rigid horizontal base plate. The thickness tester includes a device suitable for measuring the gap between the horizontal sliding plate and the horizontal base plate to within ±0.5 mm. The horizontal sliding plate and the horizontal base plate are larger than the surface of the absorbent article package that each plate contacts, i.e., each plate extends beyond the contact surface of the absorbent article package in all directions. The horizontal sliding plate applies a downward force of 850 ± 1 g (8.34 N) to the absorbent article package, which can be achieved by placing a suitable weight in the center of the upper surface of the horizontal sliding plate that does not contact the package, such that the total mass of the sliding plate plus an additional weight equals 850 ± 1 g.

[0105] Test Procedure The absorbent article package is equilibrated at 23±2°C and 50±5% relative humidity before measurement.

[0106] Lift the horizontal sliding plate and center the absorbent material package under the horizontal sliding plate so that the absorbent material inside the package is oriented horizontally (see Figure 10). Minimize the impact on the measurement by folding any handles or other packaging mechanisms on the surface of the package that will come into contact with either of the plates flat against the surface of the package. Slowly lower the horizontal sliding plate until it touches the top surface of the package, then release it. Ten seconds after releasing the horizontal sliding plate, measure the gap between the horizontal plates to within ±0.5 mm. Measure five identical packages (packages of the same size and the same number of absorbent materials) and report the arithmetic mean as the package width. Calculate the "in-bag stack height" = (package width / number of absorbent materials per stack) × 10 and report it to within ±0.5 mm.

[0107] The dimensions and values ​​disclosed herein should not be understood as being strictly limited to the exact numerical values ​​stated. Rather, unless otherwise indicated, each such dimension is intended to mean both the stated value and a functionally equivalent range around that value. For example, a dimension disclosed as "40 mm" is intended to mean "approximately 40 mm".
