Description

[Technical field]

[0001] The present disclosure relates to a disposable absorbent sanitary product comprising a chassis having first and second end portions and a central portion extending therebetween, a pair of side portions extending transversely on each side of the first end portion, and at least one fastener disposed on at least one of the side portions and / or the second end portion of the disposable absorbent sanitary product for fastening the absorbent sanitary product around the waist of a wearer. [Background technology]

[0002] Absorbent products (also called disposable absorbent hygienic products) in the form of disposable diapers and incontinence briefs (also called open diapers or all-in-one diapers) are generally known, in which the absorbent products are provided with a fastening system comprising a pair of side panels with fasteners, such as fastening tabs, fixed on either side of one end region of the diaper. The fastening tabs are intended to engage with receiving means located on the other end region of the diaper. Such diapers are generally placed on the wearer when the wearer is lying down.

[0003] Another type of absorbent product is a belted absorbent product, which allows the wearer or caregiver to apply the diaper in a standing position. A belted absorbent product (i.e., a belt product) typically has a belt that is integrally attached to the chassis of the absorbent product. The belt can have two belt portions extending on either side of the rear end of the chassis. The two belt portions are intended to be fastened around the waist of the wearer, while the front end of the absorbent section hangs down between the wearer's legs. Once the belt portions are joined together by fasteners or, for example, fastening tabs, the wearer can reach between his / her legs, pull the absorbent section up between his / her legs, and attach the free end of the absorbent section to the belt portion by a second fastener (e.g., fastener tabs, etc.). Similarly, the product can be made such that the belt is fastened to the front portion of the product and is secured around the back of the wearer. In this case, the absorbent section will hang down at the front and be secured to the belt at the back. This type of product is particularly useful for caregivers who care for patients who may have dementia or the like.

[0004] Both types of absorbent products use fastening systems to fasten the product to the wearer. Various types of fastening systems are known to connect or hold parts of the absorbent product together and / or to secure the absorbent product on the wearer of the absorbent product. Easy removal of the absorbent product and / or easy adjustment of the absorbent product during use may be desirable. Examples of refastening systems include adhesive tapes and hook-and-loop fastening systems. Hook-and-loop fastening systems are sold, for example, under the trademark Velcro®. Hook-and-loop fasteners generally include two strips or patches that are attached (glued, heat sealed, welded...) to the opposing surfaces that are to be fastened. The first strip / patch includes a hook and the second strip / patch includes a loop. When the two strips / patches are pressed together, the hook catches the loop and the two strips / patches are fastened.

[0005] Both types of absorbent products are usually folded in a bag, and during the folded state, the hook strip / patch can be (temporarily) attached onto the topsheet or backsheet of the absorbent product. Also, during use, the hook strip / patch can accidentally become attached to the topsheet or backsheet of the absorbent product, for example, during adjustment of the product. Depending on the material or materials from which the topsheet and / or backsheet are made, the hook strip / patch can accidentally come loose from the absorbent product before use or when unfolding the product during use. This can happen, for example, when peel and shear forces become too high between the hook strip / patch and other materials (such as, for example, a topsheet or backsheet that is not designed to act as a loop zone for the hook strip / patch).

[0006] This can also occur when the absorbent product is being unfolded and when the hook strip / patch is attached to its intended loop area.

[0007] Therefore, there is a desire to minimise the risk of the hook strip / patch coming loose from the product before or during use. Summary of the Invention [Problem to be solved by the invention]

[0008] It is desirable to provide an improved fastening system for disposable absorbent sanitary products which uses fasteners to fasten the absorbent product around the waist of a wearer. According to the present disclosure there is provided a disposable absorbent sanitary product according to the accompanying claims. [Means for solving the problem]

[0009] "Absorbent products" (also called disposable absorbent sanitary products) refer to consumer products that absorb and contain bodily exudates, and more specifically, to products that are placed against or in close proximity to the body of a wearer to absorb and contain various exudates discharged from the body. Absorbent products include, for example, diapers and incontinence devices. Diapers include, for example, all-in-one diapers, pant diapers, and belt diapers. Diapers can be baby, toddler, or adult diapers.

[0010] So-called all-in-one diapers (also called open diapers) are characterized by the fact that they contain fastening tabs / panels by which the front and rear portions of the diaper are joined when the diaper is applied around the waist of the wearer.

[0011] So-called pant diapers are characterized in that the front and rear parts of the diaper are joined at the waist. This type of diaper is intended to be worn by the wearer (i.e. pulled over the legs of the wearer) exactly like a pair of underpants. The joining at the waist part of the pant diaper is usually such that it can be torn open to remove it from the wearer and that it is not necessary to pull the pant down over the legs and feet of the wearer to remove it. Pant diapers usually contain elastic areas both in the waist section and around the leg openings. There are also pant diapers that can be opened and reclosed by refastening means. Such pant diapers can be opened, for example, to check if the product has been soiled or to adjust the width of the product, and then reclosed afterwards.

[0012] So-called belt-type diapers / belt products are characterized in that they comprise a belt, which is oriented transversely with respect to the chassis of the diaper and is attached integrally thereto. An absorbent core is arranged in the chassis. The belt can have two belt portions extending on either side of the rear end or the front end of the chassis. When wearing the belt-type diaper, the two belt portions are intended to be fastened around the waist of the wearer in a first stage. The front or rear end of the chassis of the belt-type diaper hangs loosely from the belt between the legs of the wearer. When the belt portions are joined together, the absorbent chassis is led between the legs of the wearer and fastened to the belt. The belt comprises a fastening surface intended to be fastened by its free transverse edge to a fastening element arranged on the chassis of the diaper. This type of product is particularly useful for caregivers who care for patients who may have dementia or the like.

[0013] Another type of belt diaper is in the form of a two-piece product, including a separate belt and a separate chassis with an absorbent structure. In use, the belt is fastened around the waist of the wearer, and the chassis is subsequently joined to the outside of the belt by hook-and-loop or tape elements at the corners of the chassis. The absorbent products according to the present disclosure are disposable products. The term "disposable" is generally used to describe absorbent products that are not intended to be washed or otherwise restored or reused as absorbent products (e.g., they are intended to be disposed of after a single use and can also be configured to be recycled, composted, or otherwise disposed of in an environmentally compatible manner).

[0014] The terms "longitudinal" or "longitudinally" refer to the length or lengthwise direction, particularly the direction running between a first and second end portion of the product or between the front and back of the wearer.

[0015] The terms "transverse" or "transversely" refer to the width or lateral direction, corresponding to the direction perpendicular to the longitudinal direction. The transverse direction runs from side to side, particularly from the left side to the right side of the wearer (and vice versa).

[0016] The disposable absorbent sanitary product according to the present disclosure comprises a chassis having first and second end portions and a central portion extending therebetween, the chassis having a body-facing surface intended to face the wearer's body and a garment-facing surface intended to face away from the wearer's body, a longitudinal axis extending in a longitudinal direction and defining a longitudinal direction from the first end portion to the second end portion, and a transverse axis defining a transverse direction perpendicular to the longitudinal direction. The chassis comprises a liquid-permeable topsheet at the body-facing surface, a liquid-impermeable backsheet at the garment-facing surface, and an absorbent core assembly including at least one absorbent core disposed between the topsheet and the backsheet. The disposable absorbent sanitary product further comprises a pair of side portions extending in the transverse direction on either side of the first end portion for fastening the disposable absorbent sanitary product to the waist of the wearer. The disposable absorbent sanitary product includes at least one fastener disposed on at least one of the side portions and / or the second end portion of the disposable absorbent sanitary product for fastening the disposable absorbent sanitary product to a waist of a wearer. The fastener includes a sheet-formed base having generally parallel upper and lower surfaces, the lower surface being attached to at least one of the side portions and / or the second end portion of the disposable absorbent sanitary product. The sheet-formed base includes at least one fastening area having a longitudinal length and a transverse width and including one or more areas of fastening material including a plurality of discrete fastening elements including stems projecting from an upper surface of the sheet-formed base. The fastening area is disposed a predetermined distance from one outer edge of the sheet-formed base disposed in a first transverse direction, forming an area on the sheet-formed base free of fastening material.The fastener is attached to the disposable absorbent sanitary product at an attachment area that at least partially overlaps the fastening area and extends outside the fastening area into an area of ​​the sheet-formed base that does not include the fastening element, but inside the outer edge of the sheet-formed base.

[0017] The pair of transversely extending side portions on either side of the first end portion for fastening the absorbent sanitary product to the waist of the wearer can be first and second belt portions when the absorbent sanitary product is a belt-type diaper (i.e. a belt product). Alternatively, the pair of transversely extending side portions on either side of the first end portion for fastening the absorbent sanitary product to the waist of the wearer can be first and second side panels when the absorbent sanitary product is an open-type diaper (i.e. an all-in-one diaper).

[0018] The sheet-molded base of the fastener having generally parallel upper and lower surfaces, with the lower surface attached to at least one of the side portions and / or the second end portion of the disposable absorbent sanitary product, can have a square shape, a rectangular shape, a round shape, or any other shape.

[0019] The fastening area of ​​the sheet-formed base, which includes one or more areas of fastening material including a plurality of discrete fastening elements including stems protruding from the upper surface of the sheet-formed base, can have the fastening elements evenly distributed throughout the area, or can have, for example, stripes of fastening elements in different zones. The stems can be, for example, hooks adapted to attach to loops. When the fasteners (i.e., areas of fastening material) are pressed together or placed over the loop material, the hooks catch on the loops and the two are fastened together. The topsheet, backsheet, or any other material of the absorbent sanitary product can act as the loop material.

[0020] The attachment area where fasteners are attached to the disposable absorbent sanitary product at least partially overlaps the fastening area, but it can overlap the entire area, as long as it extends outside the fastening area, into an area where the sheet-formed base does not contain the fastening elements, but inside the edge of the sheet-formed base.

[0021] The fastener can be attached to the disposable absorbent sanitary product at the attachment area by, for example, adhesive, ultrasonic welding, or heat sealing / welding, or a combination thereof. The attachment material (i.e., adhesive or weld) can cover all or a portion of the attachment area, for example, the weld or adhesive can be applied in stripes distributed evenly or unevenly across the attachment area.

[0022] By disposing the fastening area at a predetermined distance from one outer edge of the sheet-molded base, an area free of fastening material in a first transverse direction is generated. The outer edge can be the first outer edge. The distance can be considered to be the first distance. By projecting the attachment area into the area free of fastening material, forces are distributed in a beneficial manner when removing the fastener from the material to which it is attached (e.g., the topsheet or backsheet, or any other material of the absorbent sanitary product) when the product is unfolded after being removed from the package. When the wearer or caregiver unfolds the product, they usually grip the vicinity of the fastener with their fingers. That is, the wearer / caregiver usually grips the material near the fastener (i.e., the side portion or the second end portion) and pulls the fastener through the side portion or the second end portion. With the other hand, the wearer / caregiver usually holds the remaining part of the product. When the wearer / caregiver begins to pull on the material near the fastener, the sheet-formed base and fastener-free areas (which are attached to the side portion or second end portion by the attachment areas) begin to move with the side portion or second end portion as the wearer pulls the side portion or second end portion away from the material to which the fastener fastening areas are attached. That is, as the wearer / caregiver pulls the side portion or second end portion away, the sheet-formed base and fastening material-free areas begin to bend slightly upward / away from the material to which the fastening areas are attached. As the wearer / caregiver continues to pull the side portion or second end portion further away from the material, multiple discrete fastening elements, including the stem closest to the fastening material-free area, begin to release from the material to which it is attached, and other stems release as the wearer / caregiver pulls further until the entire fastener is released from the material. This also applies when adjusting the product.

[0023] Fasteners currently on the market are usually attached by adhesive that only partially covers the fastening area, i.e., the fastening area is larger than the attachment area and protrudes outside the outer boundary of the attachment area. When the wearer / caregiver is pulling on the side portion or the second end portion, the fastener may come loose from the side portion or the second end portion. This is because when the wearer / caregiver starts to pull on the material near the fastener, the force that removes the fastener (i.e., the discrete fastening elements) from the material to which it is attached may be greater than the force in the attachment area, especially if the material to which the fastener is temporarily attached is not designed to be used with the fastener. Thus, the fastener starts to come loose in the attachment area, and as it starts to come loose, there is a higher risk of the entire fastener coming loose instead of the discrete fastening elements releasing from the material to which they are attached.

[0024] The adhesive can be any adhesive suitable for application For example, the adhesive can be a hot melt adhesive that is applied during manufacture of the product or it can be an adhesive that is pre-applied to the fastener.

[0025] The fasteners can be manufactured by extruding a polymer into a mold that forms a sheet-molded base with integrally formed stems in the fastening areas, and by extruding a polymer onto a sheet-molded base to form stems that protrude from an upper surface of the sheet-molded base. When making the fasteners, the areas without fastening material can be left without stems or, alternatively, melted in a second step.

[0026] According to one exemplary embodiment, the first transverse direction is in a direction away from the longitudinal axis. When deploying or adjusting the fastener, the wearer or caregiver will most commonly grip with their fingers at the outer ends of the side portions and / or the outer ends of the second end portions, which are in a direction away from the longitudinal axis when the product is in its deployed state.

[0027] According to one exemplary embodiment, the fastening area is disposed in a second transverse direction, disposed in the opposite direction of the first outer edge of the sheet-formed base, disposed at a second distance from the second outer edge of the sheet-formed base, forming a second area on the sheet-formed base that is free of fastening material, and the attachment area extends into the second area where the sheet-formed base does not include the fastening elements, but inside the second edge of the sheet-formed base. By having two opposite sides in the transverse direction that the attachment area protrudes into both areas that are free of fastening areas, the attachment area is larger than the fastening area in both transverse directions. This allows the wearer or caregiver to grip either side of the fastener and still have the advantages as described above.

[0028] According to one exemplary embodiment, the fastening area is disposed a third distance from a third outer edge of the sheet-formed base disposed in a first longitudinal direction, forming a third area on the sheet-formed base that is free of fastening material, and the attachment area extends into the third area where the sheet-formed base does not include the fastening elements, but inboard of the third outer edge of the sheet-formed base.

[0029] According to one exemplary embodiment, the fastening area is disposed a fourth distance from a fourth outer edge of the sheet-formed base, which is disposed in a second longitudinal direction, forming a fourth area on the sheet-formed base that is free of fastening material, and the attachment area extends into the fourth area where the sheet-formed base does not include the fastening elements, but inboard of the fourth outer edge of the sheet-formed base.

[0030] An advantage of having third and / or fourth areas free of fastening material, and of having attachment areas extending into these areas, is that when a wearer or caregiver grasps the side portion and / or second end portion at an angle to the longitudinal direction, forces will be distributed differently, which further reduces the risk of the fasteners accidentally coming loose from the side portion and / or second end portion.

[0031] According to one exemplary embodiment, the first, second, third and / or fourth distances are between 3 and 10 mm, specifically between 3 and 6 mm, or more specifically between 3 and 4 mm.

[0032] According to one exemplary embodiment, the attachment area is located at a predetermined distance from the first and / or second and / or third and / or fourth outer edge, said distance being smaller than the first, second, third and / or fourth distance between the fastening area and the respective outer edge. Alternatively, the attachment area can extend up to the first and / or second and / or third and / or fourth outer edge, but preferably does not protrude beyond the first and / or second and / or third and / or fourth outer edge.

[0033] According to one exemplary embodiment, the fastener is attached to the disposable absorbent sanitary product at the attachment area by adhesive, welding, or heat sealing, or a combination thereof.

[0034] According to one exemplary embodiment, the fastening elements are hooks. That is, at least a plurality of discrete fastening elements, including stems protruding from the upper surface of the sheet-molded base, are hooks. By "hook" is intended to mean a hook part or surface protrusion of a hook-and-loop type fastener adapted to be fastened to a zone (called a landing zone) that includes a fibrous loop. The hooks can have any shape. Examples of hooks include pins, e.g., straight pins, angled pins, curved pins, tapered pins, limbed or multi-limbed pins, hooks, limbed or multi-limbed hooks, mushroom-shaped protrusions, and palm-tree-shaped protrusions. The hooks can have any type of cross-section, such as round, oval, square, rectangular, or polygonal. The hooks can have a solid core. Within one fastening part, all hooks can have the same shape. Alternatively, one fastening part can include several different shapes of hooks.

[0035] The fasteners can be manufactured by extruding a polymer into a mold to form a sheet-molded base with integrally formed hook or pin-like projections, and alternatively by post-forming a mushroom-shaped head on the pin-like projections. The fasteners can also be manufactured by extruding a polymer onto a sheet-molded base to form the hooks of the pin-like projections.

[0036] When making the fastener, the areas without fastening material can be left without hook or pin-like protrusions or, alternatively, can be melted in a second step.

[0037] According to one exemplary embodiment, the first end portion is a rear region of a disposable absorbent sanitary product, the second end portion is a front region of a disposable absorbent sanitary product, and the central portion is a crotch region.

[0038] According to one exemplary embodiment, the sheet-molded base protrudes beyond the outer edge of the side portion and / or the second end portion of the disposable absorbent sanitary product, thereby forming a fingerlift. The fingerlift can reduce the risk of the hook being torn off the side portion and / or the second end portion, because the wearer or caregiver can grip the hook directly, rather than through the side portion and / or the second end portion of the disposable absorbent sanitary product when unfolding or adjusting the product. Thus, when the wearer / caregiver grips the fingerlift directly (i.e., grabs the fastener directly), there may be little or no force on the attachment layer. The fingerlift (i.e., the area forming the fingerlift) can be totally or partially different from the side portion and / or the second end portion of the disposable absorbent sanitary product in terms of color, shape, or texture. The fingerlift (i.e., the area forming the fingerlift) can be totally or partially different from the rest of the fastener in terms of color, shape, or texture. Thus, a different color, shape, or texture from the side portion and / or the second end portion of the disposable absorbent sanitary product makes it easier for the wearer or caregiver to see the fastener, which may trigger the wearer or caregiver to grasp the fingerlift instead of the side portion and / or the second end portion.

[0039] According to one exemplary embodiment, the attachment area is located at a predetermined distance from the outer edge of the side portion and / or the second end portion, the distance being less than 5 mm, i.e. when a finger lift is provided, the attachment area is located at a predetermined distance from the outer edge of the side portion and / or the second end portion, the distance being less than 5 mm.

[0040] According to one exemplary embodiment, the sheet-molded base protrudes beyond the outer edges of the side portions and / or the second end portion by at least 5 mm, specifically between 5 mm and 15 mm.

[0041] According to one exemplary embodiment, when the sheet-molded base protrudes beyond the outer edge of the side portion and / or the second end portion of the disposable absorbent sanitary product forming a finger lift, the fastening area protrudes beyond the outer edge of the side portion and / or the second end portion of the disposable absorbent sanitary product and the attachment area is located a predetermined distance from the outer edge of the side portion and / or the second end portion of the disposable absorbent sanitary product.

[0042] According to one exemplary embodiment, the disposable absorbent sanitary product is a belt product, and the side portions are first and second belt portions for fastening together around a waist of a wearer of the product to form a belt having an outer surface, the first belt portion having a free end carrying the fastener adapted to be attached to the outer surface of the other of the belt portions.

[0043] According to one exemplary embodiment, the disposable absorbent sanitary product is a belt product, the side portions being first and second belt portions for fastening together around a waist of a wearer of the product to form a belt having an outer surface, the first belt portion being adapted to be attached to the outer surface of the other of the belt portions, and the second end portion of the chassis including the fastener for fastening the second end portion of the chassis to the belt portions, such that the product assumes a pant-like shape with the belt portions forming part of the waist portion of the pant.

[0044] According to one exemplary embodiment, the side portions are side panels each including a fastener, which connects the first and second end portions to one another when the product is worn, the fastener being adapted to be attached to a contact area on the second end portion. Thus, the absorbent sanitary product is an open absorbent product (i.e. a so-called all-in-one diaper).

[0045] According to one exemplary embodiment, the disposable absorbent sanitary product comprises a second pair of side portions extending in the transverse direction on each side of the second end portion, the side portions on the first end portion being side panels each including the fastener, which connect the first and second end portions to each other when the product is worn, the fastener being adapted to be attached to a contact area on each side portion of the second pair of side portions. Thus, the absorbent sanitary product is another type of open absorbent product (i.e. the so-called all-in-one diaper).

[0046] According to one exemplary embodiment, the fastener is disposed at the second end portion of the disposable absorbent sanitary product, and the topsheet and the backsheet are attached together at a bond area that at least partially overlaps the attachment area and extends outside the attachment area at least in the first transverse direction.

[0047] According to another exemplary embodiment, a disposable absorbent sanitary product is disclosed, said disposable absorbent sanitary product being a belt product comprising a chassis having first and second end portions and a central portion extending therebetween, said chassis having a body-facing surface intended to face the body of a wearer and a garment-facing surface intended to face away from the body of the wearer, a longitudinal axis extending in a longitudinal direction and defining a longitudinal direction from said first end portion to said second end portion, a transverse axis extending in a longitudinal direction, the disposable absorbent sanitary product further comprises a pair of side portions in the form of belt portions extending in the transverse direction on either side of a first end portion for fastening the absorbent sanitary product about a waist of a wearer, the disposable absorbent sanitary product further comprising ... at least one absorbent core assembly including a liquid permeable topsheet on a body facing surface, a liquid impermeable backsheet on a garment facing surface, and an absorbent core assembly including at least one absorbent core disposed between the topsheet and the backsheet, the disposable absorbent sanitary product further comprising at least one side portion in the form of a belt portion extending in the transverse direction on either side of a first end portion for fastening the absorbent sanitary product about a waist of a wearer, a fastener for fastening an absorbent sanitary product to a waist of a wearer, the fastener comprising a sheet-formed base having generally parallel upper and lower surfaces for fastening an absorbent sanitary product to a waist of a wearer, the lower surface being attached to at least one of the belt portion and / or the second end portion of the disposable absorbent sanitary product, the sheet-formed base having a longitudinal length and a transverse width, the sheet-formed base including at least one fastening area including one or more areas of fastening material including a plurality of discrete fastening elements including stems projecting from an upper surface of the sheet-formed base, the fastening area being disposed a predetermined distance from one outer edge of the sheet-formed base disposed in a first transverse direction, forming an area free of fastening material on the sheet-formed base, the fastener being attached to the disposable absorbent sanitary product at an attachment area,The attachment area at least partially overlaps the fastening area and extends outside the fastening area into an area where the sheet-formed base does not contain the fastening elements, but inside the edge of the sheet-formed base. The same advantages and features discussed above are also associated with this exemplary embodiment.

[0048] According to another exemplary embodiment, a disposable absorbent sanitary product is disclosed, said disposable absorbent sanitary product being an open-type absorbent sanitary product, comprising a chassis having first and second end portions and a central portion extending therebetween, said chassis having a body-facing surface intended to face the body of a wearer and a garment-facing surface intended to face away from the body of the wearer, a longitudinal axis extending in a longitudinal direction and defining a longitudinal direction from said first end portion to said second end portion and a transverse direction from said first end portion to said second end portion. The cross-sectional axis defines a transverse direction perpendicular to the longitudinal direction, the chassis includes a liquid permeable topsheet on a body-facing surface, a liquid impermeable backsheet on a garment-facing surface, and an absorbent core assembly including at least one absorbent core disposed between the topsheet and the backsheet, the disposable absorbent sanitary product further including a pair of side portions in the form of side panels extending in the transverse direction on either side of a first end portion for fastening the absorbent sanitary product about a waist of a wearer and a front end portion for fastening the absorbent sanitary product about a waist of a wearer. The disposable absorbent sanitary product includes at least one fastener disposed on at least one of the side panels of the disposable absorbent sanitary product for fastening the absorbent sanitary product to a waist of a wearer, the fastener comprising a sheet-formed base having generally parallel upper and lower surfaces for fastening the absorbent sanitary product to a waist of a wearer, the lower surface being attached to at least one of the side panels of the disposable absorbent sanitary product, the sheet-formed base having a longitudinal length and a transverse width, the sheet-formed base including at least one fastening area including one or more areas of fastening material including a plurality of discrete fastening elements including stems projecting from an upper surface of the sheet-formed base, the fastening area being disposed a predetermined distance from one outer edge of the sheet-formed base disposed in a first transverse direction, forming an area free of fastening material on the sheet-formed base, the fastener being attached to the disposable absorbent sanitary product at an attachment area, the attachment area beingThe sheet-formed base at least partially overlaps the fastening area and extends outside the fastening area into an area that does not include the fastening elements, but inside the edge of the sheet-formed base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0053] All figures are highly schematic and not necessarily to scale; they show only the parts necessary to elucidate the invention, other parts being omitted or merely suggested.

[0054] Various aspects of the disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments are shown. Exemplary embodiments may take many different forms, however, and should not be construed as being limited to the details of the embodiments set forth herein, but rather, these embodiments are provided for thoroughness and completeness. Like reference characters refer to like elements throughout the description.

[0055] For purposes of description herein, the terms "rear," "anterior," "longitudinal," "medial," "lateral," "external," and derivatives thereof, refer to the exemplary embodiments as oriented, for example, in FIGS. 1 and 4. However, it should be understood that the exemplary embodiments are capable of various alternative orientations unless expressly specified to the contrary. It should also be understood that the examples illustrated in the figures and described herein are merely exemplary embodiments. Thus, dimensions and other physical attributes relating to the exemplary embodiments disclosed herein should not be considered as limiting, unless expressly stated to the contrary.

[0056] This disclosure primarily refers to disposable absorbent sanitary products, which means products that are not intended to be washed or otherwise restored or reused as absorbent products after use. By "absorbent product" is meant a product that absorbs or is adapted to absorb bodily fluids (e.g., urine and / or blood) and / or contains solid bodily waste.

[0057] Figures 1 and 2 show a first embodiment of a disposable absorbent sanitary product 1 in the form of an open type product (i.e. an open type diaper). Open type diapers are generally intended to be placed on the wearer while the wearer is lying down.

[0058] The open type diaper 1 comprises a main part, i.e. a chassis 10 having a body-facing surface intended to face the wearer's body and a garment-facing surface intended to face away from the wearer's body. The chassis 10 comprises a liquid-permeable topsheet 11 on its body-facing surface, a liquid-impermeable backsheet 12 on its garment-facing surface, and an absorbent assembly 30 disposed between the topsheet and the backsheet (see FIG. 2).

[0059] In the disposable absorbent sanitary product illustrated in Figures 1 and 2, the topsheet 11 and the backsheet 12 extend outside the outer contour of the absorbent assembly 30 and are joined together outside the absorbent assembly contour using methods such as, for example, thermal or ultrasonic gluing or welding.

[0060] The chassis 10 has a first end portion 15 and a second end portion 14, where the second end portion 14 is a front end portion intended to be in the front (abdominal) waist region of the wearer and the first end portion 15 is a rear end portion 15 (i.e., rear region) intended to be in the back waist region of the wearer when the product is worn. A central portion 13 extends between the front end portion 14 and the rear end portion 15. The chassis 10 defines a longitudinal direction L extending from a front edge 4 of the front end portion 14 to a rear edge 5 of the rear end portion 15 and a transverse direction T perpendicular to the longitudinal direction L. The longitudinal side edges 2, 3 connect the front edge 4 and the rear edge 5 of the chassis on opposite sides of an imaginary longitudinal centerline C (i.e., longitudinal axis LO).

[0061] The open-type diaper 1 comprises a first pair of side portions 23, 24 which in the illustrated embodiment take the form of side panels 23, 24. They are rear side panels 23 which are attached to the chassis 10 at their longitudinal side edges 2, 3 near their rear edge 5.

[0062] A second pair of side portions 21, 22 in the form of front side panels 21, 22 are attached to the chassis 10 at their longitudinal side edges near the front edge 4. As an alternative, the open-type diaper 1 may not have a second pair of side portions at the front, i.e. it may lack the second front side panels 21, 22.

[0063] The rear side panels 23, 24 are each provided with a fastener 25 near an outer edge 26 of the rear side panel (i.e., the distal end of the rear side panel opposite the end attached to the chassis 10) that is intended to be fastened onto a garment-facing surface of the corresponding front side panel 21, 22 or onto a garment-facing surface of the chassis 10 to fit a disposable absorbent sanitary product around the waist of a wearer.

[0064] Leg elastics 17 extending in a generally longitudinal manner may be attached to the chassis 10, such as sandwiched between the topsheet 11 and the backsheet 12 proximal to the longitudinal side edges 2, 3, to provide leg cuffs for the open-type diaper 1. Alternatively or in addition to the leg elastics 17 in the exemplary embodiment of Figures 1 and 2, the defined leg cuffs may comprise one or more elastic threads, elastic film strips, or elastic foam strips, and may be attached to the chassis 10 in a stretched state to exert a longitudinal contracting force on the open-type diaper 1.

[0065] The absorbent assembly 30 is disposed between the topsheet 11 and the backsheet 12, as shown in Figure 2. The absorbent assembly 30 defines a longitudinal direction from the front end to the rear end, and a transverse direction perpendicular to the longitudinal direction. In the open-type diaper 1, the absorbent assembly 30 is aligned such that the longitudinal direction of the assembly is parallel to the longitudinal direction of the open-type diaper 1, with the front end of the absorbent assembly facing the front end of the open-type diaper 1 and the rear end of the assembly facing the rear edge of the open-type diaper 1.

[0066] As illustrated in Figures 1 and 2, the absorbent assembly 30 includes two absorbent cores, i.e., a first absorbent core 31 and a second absorbent core 32, in a superimposed relationship (i.e., placed one on top of the other such that both longitudinal ends of the second absorbent core are between (longitudinally inboard of) the longitudinal ends of the first absorbent core). However, the open-type diaper is not limited to having two cores. For example, it can have only one core or it can have three or more cores.

[0067] The first absorbent core 31 is larger than the second absorbent core 32. The first absorbent core 31 comprises cellulosic fibers (optionally mixed with a superabsorbent polymer). The first absorbent core 31 extends the entire longitudinal length of the absorbent assembly.

[0068] The secondary absorbent core 32 is positioned in the central portion 13. The secondary absorbent core 32 comprises a mixture of cellulosic fibers and high-absorbency particles.

[0069] The planar surface area of ​​the second absorbent core 32 is smaller than that of the first absorbent core, for example, it can be less than 75% of the planar surface area of ​​the first absorbent core 31, for example less than 60% or less than 50%, for example between 40% and 75%.

[0070] 1 and 2, the second absorbent core 32 is on the garment-facing side of the first absorbent core 31 and is positioned between the first absorbent core 31 and the backsheet 12. In alternative embodiments, the second absorbent core 32 can be on the body-facing side of the absorbent core 31 and can be positioned between the first absorbent core 31 and the topsheet 11.

[0071] In disposable absorbent sanitary products according to the present disclosure, in which a second absorbent core is positioned between a first absorbent core and a backsheet, the first absorbent core can act in part as a transfer layer to direct fluid away from the topsheet and into the second absorbent core, where a major portion of the liquid holding capacity is concentrated, thereby contributing to good liquid handling in the product.

[0072] The first absorbent core 31 and the second absorbent core 32 can be in direct contact with each other, meaning that there is no additional layer of material (e.g., a tissue or nonwoven core wrap layer) between the two cores.

[0073] 1 and 2, the outer contour of the absorbent assembly 30 can be hourglass shaped, with a central region having a narrower width than the anterior and posterior regions, which may be equal or different in width, for example, the posterior region may be wider than the anterior region.

[0074] In alternative embodiments, the outer contour of the absorbent assembly can take on different shapes (eg, rectangular or oval, etc.).

[0075] 1 and 2, the acquisition layer 16 can be sandwiched between the topsheet 11 and the absorbent assembly 30. Although the absorbent assembly 30 is intended to receive and retain large volumes of exudate (e.g., urine, etc.), it can be advantageous to include an acquisition layer between the topsheet 11 and the absorbent core assembly 30 to provide interim acquisition of larger volumes of liquid and to provide a layer to distribute the liquid away from the immediate area of ​​impact.

[0076] FIG. 3 shows the open diaper described in FIGS. 1 and 2 in a closed state.

[0077] FIG. 4 shows a second embodiment of a disposable absorbent sanitary product in the form of a belt product 100. The belt product generally comprises a belt and a chassis part. The belt product comprises a transverse belt connected to either the front end part or the rear end part of the chassis part of the product. When applying such a belt product, the belt is in a first stage fastened around the waist of the wearer by means of fasteners. The chassis part of the belt product, in this type of product, hangs loosely from the belt. The chassis part is then led between the legs of the wearer and attached to the belt, which by its free transverse edge comprises a fastening surface intended to adhere to a fastening member or fastening device (i.e. the second and / or third fastener) located on the chassis part.

[0078] Figures 4 and 5 show several components of the belt product 100 in a schematic manner, where the belt product 100 is shown from the side intended to face the wearer when in use.

[0079] 4, the belt product 100 includes a chassis 110 and a waist belt. The belt in this exemplary embodiment includes a pair of side portions in the form of a first belt portion 123 and a second belt portion 124.

[0080] Furthermore, the belt product 100 has a longitudinal direction L and a transverse direction T. In other words, the belt product has a length extension in the longitudinal direction L and a width extension in the transverse direction T. Moreover, the chassis 110 has a first end portion 115, a second end portion 114 and a central portion 113 extending therebetween. The first end portion 115 defines a rear end portion 115 (i.e., a rear region). The second end portion 114 defines a front end portion 114 (i.e., a front region). The chassis 110 defines a longitudinal direction L from a front edge 104 of the front end portion 114 to a rear edge 105 of the rear end portion 115 and a transverse direction T perpendicular to the longitudinal direction. Longitudinal side edges 102, 103 connect forward and rearward edges 104, 105 of chassis 110 on opposite sides of an imaginary longitudinal centerline C (ie, longitudinal axis LO).

[0081] The chassis 110 includes a first covering layer 111 (i.e., a topsheet 111), which has a first surface intended to face towards the wearer in use and a second surface intended to face away from the wearer.

[0082] A pair of side portions in the form of a first belt portion 123 and a second belt portion 124 are attached to the chassis 110 such that the first belt portion 123 and the second belt portion 124 extend on either side of a first end portion 115 of the chassis for fastening together around the waist of a wearer to form a belt having an outer surface. Thus, each of the first and second belt portions 123, 124 is connected to the chassis 110 at the rear end portion 115, respectively. The first belt portion 123 is joined to the longitudinal side edge 102 and the second belt portion 124 is joined to the opposing longitudinal side edge 103. Typically, although not strictly required, the belt portions 123, 124 may be partially or wholly elastic.

[0083] Each belt portion 123, 124 has an inner surface facing the wearer during use and an outer (external) surface facing away from the wearer during use. In the belt product 100 shown in FIG. 4, the belt portions (first belt portion 123 and second belt portion 124) extend in a transverse direction T of the belt product. The belt portions (first belt portion 123 and second belt portion 124) also extend in a longitudinal direction L and have a width. The width of the belt portions can be between 5 cm and 20 cm, for example between 7 cm and 15 cm. The first belt portion 123 and the second belt portion 124 are of the same length. In an alternative embodiment, one belt portion can be longer than the other belt portion. The combined length of the two belt portions is designed to reach around the waist of the wearer. The two belt portions 123, 124 of the belt product 100 can, in some embodiments, be formed from only one piece of material, which extends in the transverse direction T across the entire rear end portion 115 and beyond the respective longitudinal side edges 102, 103 (not shown).

[0084] The first belt portion 123 and the second belt portion 124 are attached to the chassis 110 such that the first belt portion 123 and the second belt portion 124 extend on either side of the first end portion 115 of the chassis for fastening them together around a wearer of the product. To this end, as described more fully below, the first belt portion 123 has a fastener 125 on its inner surface that faces the wearer during use. The fastener 125 is adapted to be attached to the second belt portion 124 for fastening the belt portions 123, 124 together around a wearer of the product. The fastener 125 is located near an outer edge 126 of the belt (i.e., the distal end opposite the end of the belt portion that is attached to the chassis 110).

[0085] In this example, as shown, for example, in FIG. 4, the first belt portion 123 has a free end 106 carrying a fastener 125 adapted to be attached to the outer surface of the other of the belt portions (i.e., the second belt portion 124). The outer surface of the second belt portion 124 can in some examples be provided with a mating fastening component (not shown) or itself acts as the mating fastening component. In this example, the outer surface of the second belt portion 124 acts as the mating fastening component. The fastener 125 and the mating fastening component are thereby mechanically connectable to form an interconnection between the first belt portion and the second belt portion for securing them together around the wearer of the absorbent sanitary product.

[0086] As mentioned above, the second end portion 114 of the chassis 110 includes at least one further fastening device. In Fig. 4, two fasteners 148, 149 are arranged on the second end portion 114 of the chassis for fastening the second end portion 114 of the chassis to the belt portions 123, 124, so that the product assumes a pant-like shape with the belt portions 123, 124 forming part of the waist portion of the pant. The second end portion 114 of the chassis can be fastened to the outer surface of the first belt portion 123 and / or the second belt portion 124. In other words, the front end portion of the chassis (i.e., the second end portion 114) includes a fastening device (i.e., the fasteners 148, 149) for fastening the front end portion of the chassis to the belt.

[0087] Turning now to Figure 5, the belt product 100 of Figure 4 is shown with the first and second belt portions 123, 124 folded onto the topsheet 111 to form a folded belt configuration prior to use of the product, whereby the first belt portion 123 is disposed above the second belt portion 124. The belt product is shown here in the folded belt configuration. The belt product will typically be further folded before it is placed into a package (not shown).

[0088] As illustrated in Fig. 5, the second belt portion 124 is arranged to overlap the chassis 110 of the product, and the first belt portion 123 is arranged to overlap the second belt portion 124. In other words, the second belt portion 124 is arranged to overlap the first end portion 115 (i.e., the rear end portion 115 of the chassis 110), and the first belt portion 123 is arranged to overlap the second belt portion 124. For this purpose, the fastener 125 on the free end 106 of the first belt portion 123 is releasably attached to the outer surface 124a of the second belt portion 124 (see, for example, Fig. 6).

[0089] The second belt portion 124 can be positioned to overlap the absorbent core assembly 131 of the product, and the first belt portion 123 is then positioned to overlap the second belt portion 124. Thus, prior to use of the product, when the first belt portion 123 and the second belt portion 124 are folded onto the topsheet 111 to form a folded belt configuration, the second belt portion 124 is positioned to overlap the absorbent core 131 of the product, and the first belt portion 123 is positioned to overlap the second belt portion 124 (not shown).

[0090] Furthermore, the second belt portion 124 can be releasably attached to the topsheet 111 by a breakable adhesive. In other words, when the first belt portion 123 and the second belt portion 124 are folded onto the topsheet 111 to form a folded belt configuration prior to use of the product, the second belt portion 124 is releasably attached to the topsheet 111 by a breakable adhesive (not shown).

[0091] Similarly, the first belt portion 123 can be releasably attached to the outer surface 124a of the second belt portion 124 by a breakable adhesive (not shown). In other words, the first belt portion 123 is releasably attached to the outer surface 124a of the second belt portion 124 by a breakable adhesive when the first belt portion 123 and the second belt portion 124 are folded onto the topsheet 111 to form a folded belt configuration prior to use of the product. The breakable adhesives are optional, however, they can help the belt portions stay in place during manufacturing.

[0092] The belt can be inelastic or partially elastic. A partially elastic belt means that certain parts of the belt length have elastic properties, while certain other parts of the belt length do not. In some design variations, either or both of the first or second belt portions 123, 124 include an intermediate elastic region (not shown).

[0093] As mentioned above, the belt product 100 comprises a first covering layer (i.e. the topsheet 111), which comprises a first surface intended to face towards the wearer when the belt product 100 is in use.

[0094] In Figures 4 and 5, the fastening devices 148, 149 (e.g. the first and second fasteners 148, 149) are arranged on the side of the topsheet 111 that is intended to face towards the wearer when the belt product 100 is in use. The fasteners 148, 149 are arranged on the respective longitudinal edges 102, 103 of the front end portion 114 of the topsheet 111, i.e. connected to the two front corners of the chassis 110. The fastening devices (i.e. the fasteners 148, 149 at the front end portions) are intended to be releasably connected to the belt portions 123, 124 that are intended to face away from the wearer upon application of the belt product 100 on the wearer.

[0095] When the belt product 100 is to be applied to a wearer, the belt portions 123 and 124 (forming the belt) are first fastened around the wearer's waist. The loosely hanging front end portion 114 of the belt product 100 is then guided between the wearer's legs, and the fastening devices 148, 149 are subsequently fastened to the belt portions 123 and 124 (i.e. the belt) over the wearer's stomach on the side of the belt that is oriented away from the wearer.

[0096] Also conceivable are belt products in which the belt is connected to a front end portion of the belt product, such products being applied to the wearer in a reverse manner, i.e. after the belt has been fastened around the wearer's waist, the loosely hanging rear end part is led between the wearer's legs and fastened to the belt at the back, on the side of the belt oriented away from the wearer.

[0097] To improve the fit of the belt product 100, the longitudinal edges 102, 103 of the chassis 110 can be provided with leg elastics 117 arranged substantially in the longitudinal direction L of the product. The tasks of the leg elastics 117 include improving the fit of the product and making the belt product 100 more like a textile multi-use brief / pants. The leg elastics 117 can include one or more elastic threads, which in the stretched state are joined to the topsheet by gluing or ultrasonic welding or the like. Alternatively, the leg elastics 117 can include an elastic ribbon material, for example of a foam material. The leg elastics 117 can be arranged on the side of the topsheet 111 that is intended to face away from the wearer in use.

[0098] The rear end portion 115 or the front end portion 114 of the belt product 100 can also be provided with so-called waist elastics 146 in the form of elastic elements arranged along the front edge 104 or the rear edge 105 of the belt product 100, giving the belt product 100 a soft, flexible enclosure of the wearer's waist. In FIG. 4, only the front end portion 114 of the belt product 100 is provided with waist elastics 146. The waist elastics 146 comprise thin strips of elastic foam material attached by glue to the side of the topsheet intended to face away from the wearer. The waist elastics 146 are applied in a stretched state and realize a holding together force that stretches the belt product 100 around the wearer's waist. When the fasteners 148, 149 are fastened to the belt, it is expedient that the waist elastics 146 are tensioned in the transverse direction T of the belt product 100, such that the front end part 114 has a smooth configuration on the wearer's stomach in use.

[0099] The belt product 100 comprises a second covering layer 112 arranged on the side of the first topsheet that is intended to face away from the wearer in use. The second covering layer 112 is the so-called backsheet 112. The backsheet has the same extension in the L / T plane as the topsheet. The backsheet 112 is typically substantially liquid-impermeable, although other types of covering layers can be used instead. Typically, although not strictly necessary, the topsheet and the backsheet of the belt product 100 have an hourglass shape. In other design variants, other shapes (such as, for example, rectangular shapes) can also be considered.

[0100] The topsheet 111 and the backsheet 112 can be joined together in several different ways. Examples of joining methods are gluing, heat sealing, or ultrasonic welding. For a belt product 100 including a topsheet 111 and a substantially liquid-impermeable backsheet 112, it is appropriate that the leg elastics 117 and waist elastics 146 described above are disposed between the topsheet 111 and the backsheet 112. The topsheet 111 may have a low absorption capacity in the belt product 100, where smaller amounts of bodily secretions such as occasional urine drops (e.g., early menstrual fluid) can be absorbed.

[0101] The belt product 100 comprises an absorbent assembly 130 in the form of an absorbent core 131 (see FIG. 5) arranged between a topsheet 111 and a backsheet 112. The topsheet 111 of the belt product according to this example can be liquid permeable. The absorbent core 131 has substantially the same profile as the topsheet 111 and the backsheet 112, but has a smaller surface than them. The topsheet 111 and the backsheet 112 therefore extend outside the edges of the absorbent core 131 along the entire periphery of the absorbent core 131. The absorbent core 131, like the topsheet 111 and the backsheet 112, can have front and rear end parts and a narrower crotch part located between the end parts. The belt product 100 according to this example relates to a diaper intended to be used by incontinent adults or by children who are not yet continent. During use of the belt product comprising the absorbent core 131, the front part and the front end part of the crotch part act primarily as a receiving area for urine, while the rear part and the rear end part of the crotch part act primarily as a receiving area for feces. The topsheet 111 and the backsheet 112 are connected to each other on the outside of the absorbent assembly 130 along their entire periphery.

[0102] Turning now to FIG. 6, there is shown an enlarged view of a section of the belt of the product described in relation to FIGS. 4 and 5 (i.e., the first belt portion 123 and the second belt portion 124). FIG. 6 is an exploded view of the belt portion to facilitate illustration of the components of the belt portion. As mentioned above, the first belt portion 123 of the waist belt is intended to be interconnected to the second belt portion 124 by a fastener 125 for fastening together around the wearer of the belt absorbent sanitary product. Furthermore, as described in relation to FIGS. 4 and 5, the second end portion 114 of the chassis 110 includes a fastening device (i.e., fasteners 148, 149) for fastening the second end portion 114 of the chassis to the belt portion such that the product assumes a pant-like shape with the belt portion forming part of the waist portion of the pant. The fasteners 148, 149 include two separate fasteners as shown in FIGS. 4 and 5. However, it may also be provided as an extended piece of fastener over the length of the second end portion when viewed in the transverse direction T. The second end portion 114 of the chassis may be secured to either one of the belt portions 123, 124. Typically, the second end portion 114 of the chassis 110 may be secured to both belt portions (i.e., to the outer surfaces 123a, 124a), as shown in FIG.

[0103] Furthermore, in all exemplary embodiments described herein in relation to the belt product 100, and in other possible exemplary embodiments, a portion of any one of the first and second belt portions extending from the first end portion of the product is typically permanently attached to the first end portion. In other words, the end portion of the first belt portion 123 opposite the free end portion 106 is now permanently attached to the first end portion 115 of the chassis. Similarly, the end portion of the second belt portion 124 is now permanently attached to the first end portion 115 of the chassis.

[0104] The belt portions 123, 124 can be made of one layer of fibrous material or can be a flexible laminate of at least two layers of fibrous material bonded together in a bonding pattern provided, for example, by ultrasound, laser, and / or heat. If it is a flexible laminate, at least some of the fibers in the layer of fibrous material should be meltable by such bonding techniques. As an alternative, the laminate can include at least three layers of fibrous material. One outer layer intended to form the outside of the belt is a fibrous material adapted to serve as an attachment surface for the fasteners 148, 149 on the front portion 114. Examples of nonwoven materials are spunbond materials, meltblown materials, carded bonded materials, etc. The middle layer can be made of a fibrous material with a relatively high tear strength (for example, a spunbond material or a meltblown material with continuous filaments, etc.). The other outer layer intended to form the inner layer of the belt facing the wearer can be made of soft, skin-friendly fibrous materials. Examples of suitable materials are spunbond and meltblown materials, carded bonded materials, etc. Examples of polymeric materials used in different fibrous materials suitable for this purpose include polypropylene, polyethylene, polyester, and / or so-called bicomponent fibers. The basis weight of the nonwoven laminate can vary between about 40 gsm and about 150 gsm, for example between about 60 gsm and about 120 gsm, in particular between about 75 gsm and about 105 gsm. One or more layers of the laminate can be creped. For example, the outer layer intended to act as a receiving material for fastening means (in particular as a loop material for hook-and-loop type fasteners) is creped. Creping improves the loop function of the material.

[0105] As mentioned above, belt products are typically disposable absorbent sanitary products, such as diapers and incontinence guards.

[0106] Both exemplary embodiments shown in Figures 1-6 include a topsheet 11, 111, a backsheet 12, 112, and an absorbent core assembly 30, 130 therebetween with at least one absorbent core 31, 32, 131, as described.

[0107] The topsheet in both embodiments is a liquid permeable topsheet 11, 111 that is disposed on the boldfacing side of the disposable absorbent sanitary product. Materials suitable for topsheets are commonly known in the art of disposable absorbent sanitary products, and for the purposes of this disclosure, any material commonly known for use as a topsheet material can be used, including, but not limited to, nonwoven materials and apertured polymeric films.

[0108] The topsheet 11, 111 is suitably sufficiently fluid permeable to permit exuded bodily fluids (such as, for example, urine) to penetrate through the thickness of the topsheet 11, 111. The topsheet 11 is also suitably manufactured from a material that is compliant and soft-feeling against the wearer's skin.

[0109] The topsheet 11, 111 can be manufactured from a variety of web materials, such as woven and nonwoven webs, apertured films, open cell foams, or combinations or laminates of the aforementioned materials.

[0110] In the context of this disclosure, a "nonwoven" is a manufactured sheet, web, or batt of unidirectionally or randomly oriented fibers bound by friction and / or cohesion and / or adhesion, whether or not additionally needled, except for paper and woven, knitted, tufted, stitch-bonded, or felted products incorporating bonded yarns or filaments, or products felted by wet milling. The fibers may be of natural or man-made origin, staple or continuous filaments, or formed in situ. Commercially available fibers have diameters ranging from less than about 0.001 mm to more than about 0.2 mm, and they come in several different forms: staple fibers (known as staple or chopped), continuous single fibers (filaments or monofilaments), untwisted bundles of continuous filaments (tows), and twisted bundles of continuous filaments (yarns). Nonwoven fabrics can be formed by many processes, such as meltblowing, spunbonding, solvent spinning, electrospinning, and carding.

[0111] Nonwoven materials suitable for the topsheet can be made from synthetic fibers (such as, for example, polyester or polypropylene) or natural fibers (such as, for example, cotton fibers). Blends of synthetic and natural fibers can also be used.

[0112] The nonwoven material to be used as the topsheet 11, 111 can be made of, for example, spunbond, spunbond / spunbond composite, or spunbond / meltblown composite, such as SMS (spunbond / meltblown / spunbond), SSMS, SSMMS, SMMS, nonwoven material of polypropylene or bicomponent fibers of polypropylene and polyethylene, or a combination of such materials. The topsheet 11 can also have elastic properties.

[0113] The topsheet 11, 111 can be hydrophilized to improve the tendency of urine to permeate the topsheet into the underlying structure. Methods for hydrophilizing nonwovens are known and include coating the nonwoven material with a hydrophilic coating, for example, by applying a surfactant coating, by applying a hydrophilic monomer composition and a radical polymerization initiator onto the nonwoven followed by initiating a polymerization reaction on the nonwoven, by applying a coating of hydrophilic nanoparticles, or by treating the nonwoven surface with a high energy treatment (corona, plasma), etc.

[0114] The surfactant coating can be obtained, for example, by applying a surfactant composition to the nonwoven material by any suitable means, including spraying, slot coating, kiss roll coating, and / or immersion of the material in a bath containing the surfactant. The hydrophilization treatment can be performed in-line during the assembly of the absorbent sanitary product or it can be performed separately, and the topsheet can then be delivered as a ready-to-use roll to the manufacturing plant of the disposable absorbent sanitary product.

[0115] The topsheet material can have a basis weight of 8 g / m to 20 g / m, such as, for example, 12 g / m to 17 g / m, however, the present disclosure is not limited to only topsheet materials having this basis weight.

[0116] The backsheet 12, 112 in both embodiments is disposed on the garment-facing side of the disposable absorbent sanitary product. Materials suitable for backsheets are generally known in the art of disposable absorbent sanitary products. The backsheet 12, 112 prevents exudates absorbed by the absorbent assembly from staining other external products (e.g., bed sheets, undergarments, etc.) that may come into contact with the disposable absorbent sanitary product. The backsheet 12, 112 can be substantially impermeable to liquids (e.g., urine, etc.).

[0117] The backsheet is substantially liquid impermeable, but may be breathable (i.e., gas permeable), which implies that air and other gases can pass through the backsheet 12, 112 while being substantially impermeable to liquids.

[0118] For purposes of the present disclosure, any material commonly known for use as a backsheet material can be included in the backsheet, including, but not limited to, polymeric films such as films of polyethylene, polypropylene, or copolymers of polyethylene or polypropylene, hydrophobized nonwoven materials, fluid-impermeable foams, and fluid-impermeable laminates.

[0119] The backsheet can include one or more layers of material, for example, the backsheet can be a laminate of a liquid impermeable polymeric film laminated to the absorbent assembly and a nonwoven fabric laminated to the garment side to provide a soft feel of fabric to the outer surface of the disposable absorbent sanitary product.

[0120] It is also contemplated that the backsheet may be made from or otherwise include, in whole or in part, an elastic material to provide a better fit for the product during use.

[0121] The absorbent assemblies 30, 130 in both examples can include one or more absorbent cores. The cores can be constructed from one or more layers of cellulosic fluff pulp. The cellulosic fluff pulp can be mixed with fibers or particles of a type of superabsorbent polymer material (so-called superabsorbent polymer) that chemically binds large amounts of fluids upon absorption with the formation of a fluid-retaining gel. The absorbent cores can also include superabsorbent polymer materials that are layered inside the absorbent core or connected to one or more surfaces of the absorbent core. The absorbent cores can further include additional components to improve the properties of the absorbent core. Examples of such components are binding fibers, various types of fluid distribution layers or fibers, dimensionally stabilizing components, or reinforcing fibers.

[0122] Superabsorbent polymers are well known in the field of absorbent products and are used to help improve the absorbency properties of such products. Superabsorbent polymers are constructed by water-swellable and water-insoluble polymers that, upon formation of a hydrogel, can absorb large amounts of fluid (e.g., can absorb at least 5 times the weight of an aqueous 0.9% saline solution as measured according to method NSWP241.0.R2(15)). Superabsorbent polymers for use according to the present disclosure can be inorganic or organic cross-linked hydrophilic polymers (e.g., polyvinyl alcohol, polyethylene oxide, cross-linked starch, guar gum, xanthan gum, and cross-linked polyacrylates). The polymers can be in the form of, for example, powders, granules, microparticles, films, foams, and fibers. Upon contact with fluid, such superabsorbent polymers swell by absorbing the fluid into their structure. Generally, superabsorbent polymers are capable of rapidly absorbing fluids intruded into such products and can help retain such fluids, prevent leakage, and provide a dry feel even after fluid intrusion.

[0123] The types of superabsorbent polymers used in the absorbent assemblies of the embodiments discussed herein may be the same or may vary within the assembly. For example, a superabsorbent polymer having a first set of characteristics may be used in the front and rear regions of the absorbent assembly or in the first absorbent core, and a superabsorbent polymer having a second set of characteristics may be used in the central region of the absorbent assembly or in the second absorbent core. Characteristics referred to in this section are, for example, Centrifuge Retention Capacity (CRC), Absorbency Under Load (AUL), and / or Gel Layer Penetration (GLP).

[0124] Although the acquisition layer has been described in relation to an open diaper, it can also be used in belt products. Materials suitable as acquisition layers (also referred to in the art as transfer layers or ADLs (acquisition and distribution layers)) are generally known in the art of disposable absorbent sanitary products, and for the purposes of this disclosure, any material known to those skilled in the art as useful as an acquisition layer can be used. The acquisition layer can be in the form of, for example, an airlaid layer, a spunlace layer, a high loft, a foam, or any other type of material layer that can be used in absorbent sanitary products to act as a liquid acquisition and absorption layer. The acquisition layer is suitably adapted to rapidly receive and temporarily store the exhaled liquid before it is absorbed by the absorbent core. Such an acquisition layer can be composed of, for example, an airlaid nonwoven, a spunlace nonwoven, a high loft nonwoven, or a foam material. Airlaid nonwovens can be produced by fluffing wood pulp, where the fluff fibers are dispersed into a fast moving air stream and condensed by pressure and vacuum onto a moving screen. The acquisition layer can preferably be of an air-through bonded nonwoven fabric of polyester fibers.

[0125] The term "nonwoven" is mentioned in relation to the different parts (e.g. topsheet, backsheet and / or side parts) of the disposable absorbent product disclosed in Figures 1 to 6, which, in terms of their properties, are positioned between the group of papers and cardboard on the one hand and woven fabrics on the other hand. For nonwovens, a large number of very diverse production processes are used, such as airlaid, wetlaid, spunlace, spunbond, meltblown techniques, etc. The fibers can be in the form of endless fibers or prefabricated fibers with endless length, as synthetic fibers are produced in situ, or in the form of staple fibers. Alternatively, they can be made from natural fibers or from blends of synthetic and natural fibers.

[0126] Further components commonly used in disposable absorbent sanitary products, which are shown in the figures of the present disclosure but not illustrated, can be used in disposable absorbent sanitary products according to the present disclosure For example, raised elastic members (commonly known as standing gathers) can be attached to the topsheet.

[0127] A wetness indicator (e.g., a material that changes color upon contact with urine) can be included in the disposable absorbent sanitary product (e.g., disposed between the absorbent assembly and the backsheet and visible through the backsheet, e.g., to indicate whether a wetness event has occurred).

[0128] Both exemplary embodiments of the disposable absorbent sanitary product shown in Figures 1-6 include fasteners for fastening the product to the wearer.

[0129] In Figures 1 to 3, two fasteners 25 are attached to the side panels 23, 24 of the open-type diaper 1. Each side panel has a fastener. In Figures 4 to 6, one fastener 125 is attached to the first belt portion 123 of the belt product to connect the two belt portions 123, 124 around the wearer. The fastener 125 can alternatively be attached to the second belt portion 124. Two further fasteners 148, 149 are attached to the topsheet above the second end portion 114 (i.e. the front portion of the absorbent product).

[0130] The fasteners 125, 148, 149 used in the belt product 100 may all be of the same design or they may be different. The fasteners 25 used in the open diaper 1 may both have the same design or they may be different.

[0131] One fastener will now be described in more detail and shown in an exemplary embodiment in Figures 7 to 13. The fastener shown in Figures 7 to 11 is illustrated as a fastener 125 arranged on the first belt portion 123 of the belt product 100 of Figures 4 to 6. However, the fastener described could also be a fastener 148, 149 which could be attached to the topsheet 111 on the front portion 114 of the belt product 100 or to the respective side panels 23, 24 of the open type diaper 1.

[0132] Figure 7 shows a first exemplary embodiment of a fastener 125 attached to the belt portion 123 of the belt product of Figures 4-6. The shape of the fastener 125 is rectangular, but the fastener is not limited to this shape. The fastener can have a shape such as a square, a circle, a hexagon, etc.

[0133] The fastener 125 comprises a sheet-formed base 200 (see also Figures 7a and 7b) having generally parallel upper and lower surfaces 201, 202. The lower surface 202 of the sheet-formed base 200 is attached to the belt portion 123. The sheet-formed base 200 has a width in the transverse direction T defined by a first outer edge 204 and a second outer edge 205, and a length in the longitudinal direction L of the belt diaper defined by a third outer edge 206 and a fourth outer edge 207.

[0134] The sheet-formed base 200 has one fastening area 203 that includes one area of ​​fastening material 203 that includes a plurality of discrete fastening elements including stems (not explicitly shown) that extend from the upper surface 201 of the sheet-formed base throughout the area. Alternatively, as shown in Figures 8 and 8a, the fastening area 203 includes several areas of fastening material, where it is illustrated as three areas of fastening material 203a, 203b, 203c that include a plurality of discrete fastening elements including stems that extend from the upper surface 201 of the sheet-formed base. Thus, the fastening area 203 is an area that covers all three areas of fastening material 203a, 203b, 203c (i.e., includes the spaces between the three areas of fastening material 203a, 203b, 203c).

[0135] Figure 7 shows the end of the first belt portion of Figure 4 with the fastener 125 located near the outer edge 126 of the belt 123. When opening the belt, for example, prior to use of the product, when the belt product is in a folded belt configuration, or when adjusting or removing the product on the wearer, the wearer or caregiver can grasp and pull the end of the belt portion.

[0136] As shown in Figures 7 and 7a (Figure 7a shows cross section AA of Figure 7), the fastening area 203 is located at a first distance D1 from a first outer edge 204 of the sheet-formed base 200, which is located in a first transverse direction, forming an area 208, i.e. a first area 208 without fastening material located on the sheet-formed base 200. The first transverse direction is the direction away from the longitudinal axis when the absorbent product is in its unfolded state (see Figure 4 for belt products and Figure 1 for open type diapers). The fastening area 203 is also located at a second distance D2 from a second outer edge 205 of the sheet-formed base 200, which is located in the opposite direction to the first outer edge 204 of the sheet-formed base 200, which is located in a second transverse direction, forming a second area 209 without fastening material on the sheet-formed base 200. The second transverse direction T is towards the longitudinal axis (see FIG. 4 for a belt product and FIG. 1 for an open diaper).

[0137] The fastening area 203 is disposed across the entire longitudinal direction L of the sheet-formed base 200, as shown in Figures 7 and 7b (which shows cross section BB of Figure 7), i.e., the fastening area extends between the third outer edge 206 and the fourth outer edge 207 of the sheet-formed base 200.

[0138] A second alternative embodiment of the fastener is shown in Figures 8, 8a and 8b, where the belt portion 123 and the fastener 125 are of the same design as those in Figures 7, 7a and 7b, except for the fastening area 203, which includes several areas of fastening material. Figure 8a shows section AA of Figure 8, and Figure 8b shows section BB of Figure 8. As shown in Figures 8 and 8a, the fastening area 203 is illustrated as the sum of the three areas of fastening material 203a, 203b, 203c, which include a plurality of discrete fastening elements including stems protruding from the upper surface 201 of the sheet-molded base 200. Thus, the fastening area 203 is an area covering all three areas of fastening material 203a, 203b, 203c. That is, in the transverse direction, the area is limited by the outer edges of the first area 203a and the third area 203c. Other features are the same, the same reference numerals are used, and therefore will not be described. In addition to the areas of fastening material 203a, 203b, 203c including a plurality of discrete fastening elements, adhesive can be disposed between the three areas of fastening material 203a, 203b, 203c on the upper surface 201 of the sheet-molded base 200. The adhesive can then increase the fastening force.

[0139] The fastening area 203 is not limited to having only one area of ​​fastening material as shown in Figures 7, 7a, and 7b, or to having three areas as shown in Figures 8, 8a, and 8b, it can have two or more areas of fastening material.

[0140] A third alternative embodiment of the fastener is shown in Figures 9, 9a and 9b, in which the belt portion 123 and the fastener 125 are of the same design as those in Figures 7, 7a and 7b, except for the fastening area 203 in section BB in Figure 7b. The other features are the same, the same reference numbers are used and therefore will not be described. Figure 9a shows section AA in Figure 9 and Figure 9b shows section BB in Figure 9. Figures 9 and 9b show that in addition to the first distance D1 and the second distance D2 and the respective first and second areas 208, 209 free of fastening material as described in Figures 7 and 7a and also shown in Figure 9a, the fastening area 203 can also be located at a third distance D3 from a third outer edge 206 of the sheet-formed base 200, located in the first longitudinal direction, forming a third area 210 free of fastening material on the sheet-formed base 200. Additionally, the fastening area 203 may be disposed a fourth distance D4 from a fourth outer edge 207 of the sheet-formed base, which is disposed in a second longitudinal direction, forming a fourth area 211 free of fastening material on the sheet-formed base 200. In other words, Figure 9 illustrates a fastener 125 in which the fastening area 203 is surrounded by a larger area free of fastener material combined by all four areas 208, 209, 210, 211 free of fastening material.

[0141] Alternatively (not shown), the fastening area 203 can only be located at a first distance from one outer edge of the sheet-formed base, which is located in a first transverse direction, forming an area on the sheet-formed base that is free of fastening material. For example, the first transverse direction can be a direction away from the longitudinal axis when the absorbent product is in its unfolded state (see FIG. 4). Thus, on all other sides, the fastening material can extend to the outer edge of the sheet-formed base. Figures 7a and 7b show a fastener 125 attached to a disposable absorbent sanitary product in an attachment area 212 that overlaps with the fastening area 203 and extends outside the area of ​​the fastening area 203 into areas 208, 209 where the sheet-formed base 200 does not contain fastening elements, but inside the outer edges 204, 205 of the sheet-formed base 200. Thus, the attachment area 212 does not protrude beyond the outer contour of the fastener 125. The attachment area 212 is the area where the fasteners are attached to the underlying material, for example by adhesive, heat sealing, or welding, or a combination thereof. The welds achieved by adhesive, heat sealing, or welding can be located throughout the entire attachment area, i.e., can cover the entire attachment area, or can be distributed throughout the area as long as the fasteners are attached within the areas 208, 209 that do not include fastening elements, but inside the outer edges 204, 205 thereof.

[0142] In Figures 7a and 7b, the attachment area 212 is adhesive and overlaps almost the entire fastening area 203 in the transverse direction T (see Figure 7a). 212 is the length L of the fastening area 203 in the transverse direction 2037b, the attachment area 112 overlaps the entire fastening area except for a small area along the third and fourth outer edges 206, 207 due to the undesirability of having adhesive on the outside of the fastener. Alternatively, the attachment area could be disposed all the way up to the third and fourth outer edges 206, 207. Thus, the area of ​​the attachment area 212 is greater than the area of ​​the fastening area 203.

[0143] By making the attachment area 112 larger than the fastening area 203, the forces are distributed in a beneficial manner, reducing the risk of the fasteners tearing from the chassis or belt. This occurs especially when the attachment area 212 extends into the fastener-free first area 208, which is in a direction away from the longitudinal direction when the product is in its deployed state and in a direction that the wearer or caregiver would normally grip with his or her fingers at the outer end of the first belt portion 123 when deploying the product or adjusting it on the wearer. When the wearer or caregiver begins to pull on the outer end of the first belt portion 123, the sheet-formed base 200 and the area 208 free of fastening material (which are attached to the first belt portion 123 by the attachment area 212) begin to move with the belt portion 213 as the wearer or caregiver pulls the belt portion away from the material to which the fastening area 203 of the fastener is attached.

[0144] That is, as the wearer or caregiver pulls the belt portions 123 apart, the sheet-formed base 200 and the area 208 free of fastening material begin to bend slightly upward / away from the material to which the fastening area 203 is attached. As the wearer or caregiver continues to pull the outer end of the first belt portion 123 further away from the material, the multiple discrete fastening elements, including the stem closest to the area 208 free of fastening material, begin to release from the material to which it is attached, with other stems releasing as the wearer or caregiver pulls further, until the entire fastener 125 is free from the material. This also applies when adjusting the product.

[0145] 8, 8a, and 8b. In FIG. 8a, the length L 212 is the length L of the fastening area 203 defined by the three areas of fastening materials 203a, 203b, and 203c in the transverse direction. 203 8b), the attachment area 112 overlaps the entire fastening area, except for a small area along the third and fourth outer edges 206, 207 due to the desire to avoid having adhesive on the outside of the fastener. Thus, the area of ​​the attachment area is greater than the area of ​​the fastening area.

[0146] Figure 9a shows the section AA of Figure 9, which is the same as that of Figure 7a and will therefore not be described. Figure 9b shows a longitudinal section in which the attachment area 212 extends inside the third and fourth outer edges 206 and 207 of the sheet-formed base 200, respectively, but also into the third and fourth areas 210 and 211 where the sheet-formed base 200 is free from fastening elements.

[0147] The respective distances D1, D2, D3 and D4 discussed in relation to Figures 7, 7a, 7b, 8, 8a, 8b, 9, 9a and 9b from the fastening area 203 to one outer edge 204, 205, 206, 207 of the sheet-formed base, i.e. when there is an area on the sheet-formed base without fastening material, can be between 3 mm and 10 mm, for example between 3 mm and 6 mm, specifically between 3 mm and 4 mm.

[0148] The fastening area 203 illustrated in Figures 7-9b includes a plurality of discrete fastening elements (not shown) including stems protruding from the upper surface of the sheet-molded base. These stems are hooks that form a hook-and-loop (hook and loop) connection with the material of the second belt portion 124 that forms a hook and loop on the first belt portion 123. When the fastener 125 is used on a belt product at the front end portion 114 on the topsheet 111 (i.e. connected to the two front corners of the topsheet), the outer layers of the two attached belt portions act as loop elements to secure the second end portion (i.e. the front end portion 114 of the chassis) to the belt portions, such that the product assumes a pant-like shape with the belt portions forming part of the waist portion of the pant.

[0149] When the fastener 125 illustrated in Figures 7-9b is used in an open-type diaper, the fastener 125 illustrated in Figures 7-9b is the fastener 25 of Figures 1-3. The fastener 25 (i.e. the fastener illustrated in Figures 7-9b) is arranged on the rear side panels 23, 24, which are attached to the chassis 10 at their longitudinal side edges near the rear end of the chassis 10. The fastener 25 is intended to be fastened onto the garment-facing surface of the corresponding front side panels 21, 22 or onto the garment-facing surface of the chassis 10 in order to fit the disposable absorbent sanitary product around the waist of the wearer, which will act as a loop element.

[0150] Figures 10 and 10a show a fourth embodiment of a fastener 125' having a design almost similar to that of the fastener 125 described in Figures 7, 7a, 7b. It can also have the design described in relation to Figures 8, 8a, 8b or 9, 9a, 9b. Only the differences between the fourth embodiment and Figures 7, 7a, 7b will be described. The fastener 125' comprises a fingerlift portion 226, which is part of the first area 208 without fastening material on said sheet-formed base 200. The sheet-formed base 200 protrudes beyond the outer edge 126 of the first belt portion 123 in the belt product, forming the fingerlift 226.

[0151] If the fastener 125' is placed on the second end portion 114 of a belt-type diaper, the sheet-formed base 200 protrudes beyond the outer edge of the second end portion (i.e., the front end portion 114, also called the transverse front portion) to form a finger lift (not shown). If the fastener is placed on the side panels 23, 24 of an open-type diaper, the sheet-formed base 200 protrudes beyond the outer edge of the side panels to form a finger lift (not shown). The attachment area 212' is similar to the attachment area 212 in Figures 7, 7a, and 7b. The attachment area 212' does not protrude beyond the outer edge 126, since it is not desirable to have adhesive on the outside of the product.

[0152] The fingerlift portion can help the caregiver to find the opening of the absorbent product before use (i.e., to identify the end of the belt) or to easily find the fastener during use. The fingerlift portion allows the wearer to grasp the fingerlift portion with their fingers. The fingerlift can reduce the risk of the fastener being torn from the belt or side panel or second end because the wearer can grasp the fastener directly when unfolding or adjusting the product, instead of through the material to which the fastener is attached. Thus, the attachment strength between the fastener and the part to which the fastener is attached can be reduced.

[0153] The fingerlift portion or the entire fastener can be provided in a color different from the color of the belt, side panels, and / or chassis to allow the wearer to easily see the fingerlift portion. The sheet-molded base 200 when forming the fingerlift protrudes beyond said outer edge 126 by at least about 5 mm, for example, between about 5 mm and about 15 mm.

[0154] FIG. 11 shows an alternative fastener 125″ to the fastener 125′ in FIGS. 10 and 10a, where both the sheet-molded base 200 and the fastening area 203 protrude beyond the outer edge 126 of the belt portion 123, but still leaving an area 208 without fastening elements. The area 208 without fastening elements forms a fingerlift 226. The attachment area 212′ can have the same dimensions as those described and shown in FIGS. 10 and 10a, except that on the side with the fingerlift 226, the attachment area 212′ is located within the fastening area 203.

[0155] Figures 12 and 13 show the fastener 125' of Figures 10 and 10a as the fastener 148 of Figure 4. The fastener 125', 148 is disposed on the topsheet 111 at the second end portion 114 of the belt product 100. The topsheet 111 and the backsheet 112 are attached together by a bond area 127. The bond area 127 overlaps with the attachment area 212' described in relation to Figures 10 and 10a, and the bond area 127 extends outside the attachment area 212' in at least one direction.

[0156] Figure 13 (which shows cross section AA of Figure 12) shows that the bond area 127 overlaps the entire attachment area 212' and extends outside the attachment area 212' in both transverse directions T. The same is true for the longitudinal direction L, which can be seen in Figure 12. Thus, the bond area 127 extends outside the attachment area 212' in all directions. This reduces the risk that the fastener will tear from the topsheet when unfolding or adjusting the product, because a stronger laminate is provided.

[0157] In the longitudinal direction L, the sheet-formed base 200 and the attachment area 212' can have the same dimensions as described in Figure 7b or Figure 9b. The topsheet 111 and the backsheet 112 are attached to each other in the bond areas, for example by gluing, heat sealing, or ultrasonic welding.

[0158] As shown in Figure 12, the fastening area 203 can be located in longitudinal alignment with the leg elastics 117 to ensure a good fit and sealing to the body to avoid leakage. This applies to any of the fasteners shown in Figures 7, 7a, 7b, 8, 8a and 8b or 9, 9a and 9b when they are located on the topsheet 111 at the second end portion 114 of the belt product 100.

[0159] Additionally, the present disclosure covers all possible combinations of the described aspects, modifications, alternatives, and exemplary embodiments of the present disclosure.

[0160] It has been disclosed that open and belt diapers can include the fasteners of Figures 7-11 in various locations. It should be understood that within one diaper, different fasteners can be used in the different locations described. Alternatively, the same type of fastener can be used for all locations.

[0161] It has been disclosed that open-type diapers and belt-type diapers can include the fasteners shown in Figures 7-11, however, pant-type diapers which can be opened and reclosed by refastening means can also have the fasteners shown in Figures 7-11.
