Description

Technical Field

[0001] The present disclosure relates to a disposable absorbent sanitary product, comprising a base having a first end portion and a second end portion and a central portion extending between the first end portion and the second end portion, a pair of side portions extending in a transverse direction on each side of the first end portion, and at least one fastener arranged on at least one of the side portions and / or the second end portion of the disposable absorbent sanitary product to fasten the absorbent sanitary product to the waist of a wearer. Background Art

[0002] Generally known are absorbent products in the form of disposable diapers and incontinence briefs, also called disposable absorbent hygiene products, also called open diapers or all-in-one diapers, in which the absorbent products are provided with a fastening system comprising a pair of side panels having fasteners, such as fastening tabs, fixed to both sides of one end region of the diaper. The fastening tabs are intended to engage receiving means located on the other end region of the diaper. Such diapers are usually placed on the wearer while 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.

[0004] Absorbent products with belts, i.e. belted products, typically have a belt that is integrally attached to the base of the absorbent product. The belt may have two belt portions extending on either side of the rear end of the base. The two belt portions are intended to be fastened around the waist of the wearer, while the front end of the absorbent section is suspended between the legs of the wearer. Once the belt portions have been joined together by fasteners or such as fastening tabs, the wearer can reach between his or her legs to pull up the absorbent section between the legs and attach the free end of the absorbent section to the belt portion by a second fastener such as a fastening tab. Similarly, the product can be made so that the belt is fastened to the front portion of the product and fixed around the back of the wearer. In this case, the absorbent section will be suspended in the front and will be fixed to the belt at the back. This type of product is particularly useful for caregivers who are caring for patients who may suffer from dementia or the like.

[0005] Both types of absorbent products use fastening systems to fasten the product to the wearer. Various types of fastening systems for connecting or holding together parts of an absorbent product and / or for securing an absorbent product to the wearer of the absorbent product are known. Easy removal of the absorbent product and / or easy adjustment of the absorbent product during use may be desirable. Examples of refastening systems include tape and hook-and-loop fastening systems. Hook-and-loop fastening systems are available, for example, under the trademark Sold. Hook-and-loop fasteners usually consist of two strips or patches attached (glued, heat-sealed, welded...) to opposite surfaces to be fastened. The first strip / patch comprises the hooks and the second strip / patch comprises the loops. When the two strips / patches are pressed together, the hooks are captured in the loops and the two strips / patches are fastened.

[0006] When in use, both types of absorbent products will be fastened to the wearer as described above by one or more fasteners fastened to designated fastening areas of the product (e.g., complementary hook / loop elements). In addition, in order to adjust the fit of the product, or to remove the product from the wearer, it is necessary to be able to remove the fasteners from the fastening location. In addition, both types of absorbent products may initially be provided in a folded state, wherein the fasteners may be fastened to designated fastening areas of the product, or to another portion of the product.

[0007] For example, both types of absorbent products are usually folded in a bag, and during the folded state, the hook strip / patch can be temporarily attached to the top sheet or back sheet of the absorbent product. In addition, during use, such as during adjustment of the product, the hook strip / patch may be accidentally attached to the top sheet or back sheet of the absorbent product.

[0008] In the above-exemplified situations where the wearer or caregiver has to handle the fasteners, it is desirable to provide a product with fasteners that are easy to identify and use.

[0009] When removing a fastener from a fastening position (where it is fastened to an underlying material, e.g., to a designated fastening area or another area of ​​the product), peel and shear forces need to be overcome to break the connection between the fastener and the underlying material. Therefore, if a wearer or caregiver fails to identify the fastener and attempts to remove the fastener from the fastening position by grasping and pulling on the product component carrying the fastener (e.g., pulling on a strap or side portion to which the fastener is attached), there may be a risk that the force applied will damage the material of the strap or side portion, and / or remove the fastener from the product component by breaking the attachment to the product component, rather than removing the fastener from the fastening position.

[0010] Therefore, there is a need to provide a product having a fastener that facilitates identification of the fastener to reduce the risk of a user or caregiver grasping another portion of the product when desiring to remove the fastener from a fastened location.

[0011] The application and removal of absorbent products to and from a wearer may be performed under various conditions, such as in poor lighting conditions, such as when it is undesirable to disturb the user by lighting at night. In addition, the user's mobility or other conditions may require a caregiver to apply or remove the product to or from the user from a location where the fasteners may be difficult to reach and / or see. Therefore, it is desirable to provide a product having fasteners that facilitate identification of the fasteners when visual identification is not possible. Summary of the invention

[0012] It would be desirable to provide an improved disposable absorbent hygiene product which uses a fastener to fasten the absorbent product to the waist of a wearer and which meets one or more of the above needs.According to the present disclosure, there is provided a disposable absorbent hygiene product according to the appended claims.

[0013] "Absorbent products" are also called disposable absorbent sanitary products, and refer to consumer products that absorb and contain body exudates, and more specifically, products that are placed against or near the wearer's body 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 diapers for infants, young children, or adults.

[0014] So-called all-in-one diapers, also called open diapers, are characterized in that they comprise fastening tabs / fastening panels by means of which the front and rear parts of the diaper are joined when the diaper is applied around the waist of the wearer.

[0015] So-called pant diapers are characterized in that the front and back of the diaper are joined at the waist. Diapers of this type are intended to be worn on the wearer exactly like a pair of underpants, i.e. pulled over the legs of the wearer. The join at the waist of a pant diaper can usually be disconnected to remove the pant diaper from the wearer, so that it is not necessary to pull the pants down over the legs and feet of the wearer to remove the pant diaper. Pant diapers usually include elastic areas in the waist section and around the leg openings. There are also pant diapers that can be opened and reclosed by a refastening device. Such pant diapers can, for example, be opened to check whether the product is soiled or in order to adjust the width of the product, and then reclosed.

[0016] So-called belted diapers / belted products are characterized in that they comprise a belt oriented transversely with respect to the base of the diaper and integrally attached to the base. The absorbent core is arranged in the base. The belt may have two belt parts extending on either side of the rear end or the front end of the base. When the belted diaper is put on, the two belt parts are intended to be fastened around the waist of the wearer in a first stage. The front or rear end of the base of the belted diaper hangs loosely from the belt between the legs of the wearer. Once the belt parts have been joined together, the absorbent base is guided between the legs of the wearer and fastened to the belt. The belt comprises a fixing surface, which is intended to adhere to a fixing element arranged on the base of the diaper by its free transverse edge. This type of product is particularly useful for caregivers who care for patients who may suffer from dementia or the like.

[0017] Another type of belt diaper is a two-piece product that includes a separate belt and a separate chassis with an absorbent structure. When used, the belt is fastened around the waist of the wearer, and then the chassis is joined to the outside of the belt by hook-and-loop elements or tape elements in the corners of the chassis.

[0018] The absorbent products according to the present disclosure are disposable products. The term "disposable" is used to describe absorbent products that are generally not intended to be laundered or otherwise restored or reused as absorbent products, e.g., they are intended to be discarded after a single use and may also be configured to be recycled, composted, or otherwise disposed of in an environmentally compatible manner.

[0019] The terms "longitudinal" or "longitudinally" relate to the length or lengthwise direction, and in particular the direction extending between a first end portion and a second end portion of a product or between the front and back of a wearer.

[0020] The term "lateral" or "transversely" relates to the width or broad dimension and corresponds to a direction perpendicular to the longitudinal direction. The transverse direction extends from one side to the other, in particular from the left side to the right side of the wearer and vice versa.

[0021] A disposable absorbent sanitary product according to the present disclosure includes a substrate having a first end portion and a second end portion and a central portion extending between the first end portion and the second end portion, the substrate having a body-facing surface intended to face the body of the wearer and a clothing-facing surface intended to face away from the body of the wearer, extending in the longitudinal direction and defining a longitudinal axis from the first end portion toward the longitudinal direction of the second end portion and defining a transverse axis perpendicular to the longitudinal direction. The substrate includes a liquid-permeable top sheet at the body-facing surface, a liquid-impermeable back sheet at the clothing-facing surface, and an absorbent core assembly including at least one absorbent core arranged between the top sheet and the back sheet. The disposable absorbent sanitary product also includes a pair of side portions extending in the transverse direction on each side of the first end portion to fasten the disposable absorbent sanitary product to the waist of the wearer. The disposable absorbent sanitary product includes at least one fastener, which is arranged on at least one of the side portions and / or the second end portion of the disposable absorbent sanitary product to fasten the disposable absorbent sanitary product to the waist of the wearer. The fastener comprises a base formed of a sheet having a substantially parallel upper surface and a lower surface, the lower surface being attached to at least one of the side and / or the second end portion of the disposable absorbent sanitary product. The sheet-formed base has a length in the longitudinal direction and a width in the transverse direction, and comprises at least one fastening region, the fastening region comprising one or more fastening material regions, the fastening material region comprising a plurality of discrete fastening elements, the fastening elements comprising rods protruding from the upper surface of the sheet-formed base. The fastening region is arranged at a distance from an outer edge of the sheet-formed base, and a fastening material-free region is formed on the sheet-formed base. The fastener is attached to the disposable absorbent sanitary product in an attachment region that at least partially overlaps the fastening region.

[0022] If the absorbent sanitary product is a belt-type diaper, i.e., a belt-type product, the pair of side portions extending along the transverse direction on each side of the first end portion to fasten the absorbent sanitary product to the waist of the wearer may be the first belt portion and the second belt portion. Alternatively, if the absorbent sanitary product is an open diaper, i.e., an all-in-one diaper, the pair of side portions extending along the transverse direction on each side of the first end portion to fasten the absorbent sanitary product to the waist of the wearer may be the first side panel and the second side panel.

[0023] The sheet-formed base of the fastener has substantially parallel upper and lower surfaces, wherein the lower surface is attached to at least one of the side portions and / or the second end portion of the disposable absorbent sanitary product, and the sheet-formed base of the fastener may have a square, rectangular, circular or any other shape.

[0024] For example, the sheet-formed base may have a rectangular shape, which may facilitate manufacture using strips of base material and minimize spillage of material.

[0025] The fastening area of ​​the base formed by the sheet includes one or more fastening material areas, the fastening material area includes a plurality of discrete fastening elements, the fastening elements include a rod protruding from the upper surface of the base formed by the sheet, and the fastening area of ​​the base formed by the sheet can have fastening elements uniformly distributed over the entire area or in different zones, for example, strips of fastening elements. The rod can be, for example, a hook suitable for attachment to a loop. When the fastener (i.e., the area of ​​the fastening material) is pressed together with the loop material or arranged on the loop material, the hook is captured in the loop and the two are fastened to each other. The top sheet, back sheet or any other material of the absorbent sanitary product can be used as the loop material.

[0026] By arranging the fastening area at a distance from one outer edge of the base formed by the sheet material, a region without fastening material is created. The outer edge may be a first outer edge. The distance may be considered a first distance. The fastening area may be arranged at a distance from one outer edge of the base formed by the sheet material in a first transverse direction.

[0027] The fastener may be manufactured by extruding a polymer into a mold forming the sheet-formed base, with an integrally formed stem in the fastening region. The fastener may also be manufactured by extruding a polymer onto the sheet-formed base to form a stem protruding from the upper surface of the sheet-formed base. When manufacturing the fastener, the fastening material-free region may be free of stems, or alternatively melted in a second step.

[0028] The first transverse direction may be a direction away from the longitudinal axis. When unfolding, removing or adjusting the product, most commonly, the wearer or caregiver grasps the outer ends of the side portions and / or the outer ends of the second end portions with his / her fingers when the product is in its unfolded state.

[0029] According to a first aspect, the above object is achieved by a product according to the attached claim 1. Thus, the fastening material free area has a greater bending stiffness than the side portion and / or the second end portion to which the fastener is arranged.

[0030] Therefore, the fastener includes a region without fastening material extending from the outer edge of the base formed by the sheet, and the region without fastening material has a greater bending stiffness than the bending stiffness of the side and / or second end portion to which the fastener is arranged. When the fastener is in a fastening position in which the fastening region is fastened to the underlying material, the region without fastening material will remain free and not fastened to the underlying material, regardless of whether the article is in a closed state around the user or, for example, in a folded delivery state. Therefore, when attempting to remove the fastener from the fastening position, that is, disconnecting the connection between the fastening region and the underlying material, the region without fastening material can be identified by the user's finger touch. In addition, since the region without fastening material has a greater bending stiffness than the side and / or second end portion, when the user strives to find the fastener, the side and / or second end portion can yield more easily than the region without fastening material of the fastener away from the user's fingers. Thus, the area without fastening material will form a free edge portion that can be identified by the user's sense of touch and that indicates the correct position at which the fastener is to be pulled to be released from the underlying material. The user will be prompted to grasp the area without fastening material, rather than the side and / or second end portion to which it is attached, to remove the fastener from its connection with the underlying material.

[0031] Furthermore, according to a second aspect, the above object is achieved by a product according to the attached claim 22. Thus, the distance from a first outer edge of the base formed by the sheet material, where the fastening area is located, is at least 5 mm. Furthermore, the fastening material-free area has an extension of at least 20 mm in a direction perpendicular to the distance.

[0032] Therefore, the fastener includes a non-fastening material area extending from the outer edge of the base formed by the sheet, and the non-fastening material area has a minimum size defined by the above means. When the fastener is in a fastening position in which the fastening area is fastened to the lower material, the non-fastening material area will remain free and not fastened to the lower material, regardless of whether the article is in a closed state around the user or, for example, in a folded delivery state. Therefore, when trying to remove the fastener from the fastening position, that is, disconnecting the connection between the fastening area and the lower material, the non-fastening material area can be identified by the user's finger touch. Therefore, the non-fastening material area will form a free edge portion, which can be identified by the user's touch, and the free edge portion indicates the correct position where the fastener will be pulled to release from the lower material. Due to the suitable size of the non-fastening material area, the user will be prompted to grasp the non-fastening material area, rather than the side and / or second end portion to which it is attached, to remove the fastener from its connection with the lower material.

[0033] Although the above-mentioned first aspect and second aspect can achieve the object of the present invention alone as described above, the two aspects may be combined.

[0034] Therefore, a product according to the preamble of any one of the attached claims 1 or 22 can be provided, wherein the area without fastening material has a greater bending stiffness than the bending stiffness of the side and / or second end portion to which the fastener is arranged, and the fastening area is arranged at a distance from a first outer edge of a base formed by the sheet material on which the fastening area is arranged, the distance being at least 5 mm, and the area without fastening material has an extension range of at least 20 mm in a direction perpendicular to the distance.

[0035] In the following, many additional optional features, advantages and embodiments will be described. Each of these features, advantages and embodiments, alone or in combination, is also applicable to the first aspect, the second aspect and the combination of the first and second aspects.

[0036] As mentioned above, the fastening material free area may have a greater bending stiffness than the side and / or second end portion to which the fastener is arranged.

[0037] Thus, the stiffness of the side and / or second end portion may be such that it yields more easily under a user's fingers than areas without fastening material, thereby enabling the user to identify the fastener.

[0038] For example, the area without fastening material may have a bending stiffness that is at least 15%, such as at least 20%, greater than the bending stiffness of the side and / or second end portion. Thus, the difference in stiffness may allow a person grasping the fastener to easily identify and find the area without fastening material rather than the side and / or second end portion.

[0039] Thus, the bending stiffness of the area without fastening material may be selected depending on the bending stiffness of the side portion and / or the second end portion to which it is attached.

[0040] For example, the side of the absorbent sanitary product (such as a side panel) can be made of a material with relatively low stiffness (such as a nonwoven material). For example, such a side panel can have a bending stiffness of no more than 15 mgf, such as no more than 10 mgf. The side panel can have a bending stiffness greater than 1 mgf or greater than 5 mgf.

[0041] Thus, for example, the bending stiffness of the fastening material-free region may be selected to be, for example, at least 20 mgf, such as at least 22 mgf.

[0042] Thus, in one example, the bending stiffness of the side portion and / or the second end portion may be no greater than 10 mgf, and the bending stiffness of the area without fastening material may be at least 20 mgf, such as at least 22 mgf. For example, the fastener may be arranged to the side panel, wherein the bending stiffness of the side panel may be no greater than 10 mgf, and the bending stiffness of the area without fastening material of the fastener may be at least 20 mgf.

[0043] However, in order to provide easier identification, the bending stiffness of the fastening material-free area may still be selected to be, for example, at least 30 mgf, such as at least 40 mgf or at least 45 mgf.

[0044] For example, the bending stiffness of the side portion and / or the second end portion may be at least 30 mgf, such as at least 35 mgf. This may be preferred, for example, when the side portion is a belt part of a belt-type product.

[0045] For example, the bending stiffness of the fastening material-free area may be at least 30 mgf, such as at least 40 mgf or at least 45 mgf.

[0046] Thus, in one example, the bending stiffness of the side portion and / or the second end portion may be at least 35 mgf, and the bending stiffness of the fastening material free area may be at least 40 mgf, such as at least 45 mgf.

[0047] Considering that the side and / or second end portion need to be flexible enough to adapt to the wearer without causing discomfort, the bending stiffness of the side and / or second end portion can be further selected. For example, the bending stiffness of the side and / or second end portion can be no more than 90 mgf, such as no more than 80 mgf or no more than 70 mgf. The bending stiffness of the area without fastening material can also be selected considering the comfort of the user. Therefore, the bending stiffness of the area without fastening material can be, for example, no more than 100 mgf, such as no more than 90 mgf or no more than 70 mgf.

[0048] In another example, the disposable absorbent hygiene product is a belted product, and the side portions are a first belt portion and a second belt portion for being fixed to each other around the waist of a wearer of the product to form a belt having an outer surface, wherein the first belt portion has a free end, the free end carrying the fastener adapted to be attached to the outer surface of the other of the belt portions. Optionally, in this example, the bending stiffness of the first belt portion can be at least 35 mgf, and the bending stiffness of the fastening material-free area can be at least 40 mgf, such as at least 45 mgf.

[0049] For example, the fastener free region may be a continuous region comprising a base formed of a sheet of material. This provides for easy and efficient manufacture, wherein the fastener may be provided as a single unit for attachment to the side and / or end portions.

[0050] The fastening material-free area may, for example, include only one layer. For example, the fastening material-free area may include a single layer of nonwoven material or polymer film material. In other examples, the fastening material-free area may partially or completely include more than one layer. For example, the fastening material-free area may include a laminate of a nonwoven layer and a polymer film layer.

[0051] As described above, the distance from a first outer edge of the base formed by the sheet to the fastening area can be at least 5 mm. Therefore, the area without fastening material can have a size that facilitates the discovery of the fastener. In addition, when the distance is at least 5 mm, the user can grasp the area without fastening material when removing the fastener from the connection with the underlying material. Therefore, the area without fastening material can provide a portion that is suitable for grasping and tactilely recognizable when the fastener is in a fastened position, wherein the fastener is attached to the underlying material via the fastening area.

[0052] For example, the fastening area may be arranged at a distance from the first outer edge of the base formed by the sheet material, arranged in the first transverse direction. Thus, the area without fastening material may provide a portion suitable for grasping the fastener from the transverse direction of the product. For example, the fastening area may be arranged at a distance from the first outer edge of the base formed by the sheet material, arranged in the first transverse direction away from the longitudinal axis. Thus, the area without fastening material may provide a portion suitable for grasping at the outer end portion of the side portion and / or the second end portion, for example at the outer end portion of the belt or the side panel.

[0053] The fastening material free area may have a transverse width equal to the distance from said one first outer edge of the base formed by the sheet of material to the fastening area.

[0054] The lateral width of the fastening material-free area refers to any lateral width of the fastening material as may be measured in a direction parallel to the lateral axis.

[0055] For example, the distance (e.g., lateral width) can be at least 10 mm. In this way, the gripping of the area without fastening material can be further promoted. For example, the distance (e.g., lateral width) can be 5 to 15 mm, or 10 to 15 mm.

[0056] For example, the area without fastening material may have an extension in a direction perpendicular to the distance. Thus, when the distance is the transverse width, the extension may be the longitudinal length of the area without fastening material.

[0057] For example, the distance (e.g., lateral width) may be at least 5 mm over a continuous extension range of at least 20 mm (e.g., in the longitudinal length) perpendicular to the distance without fastening material area, for example over a continuous extension range of at least 30 mm (e.g., in the longitudinal length) or over a continuous extension range of at least 50 mm (e.g., in the longitudinal length), or any other range mentioned above.

[0058] In an alternative, the distance may be constant over a continuous extension in a direction perpendicular to the distance. For example, the transverse width may be constant over a continuous longitudinal length.

[0059] In another alternative, the distance may vary over a continuous extension in a direction perpendicular to the distance. For example, the transverse width may vary over a continuous longitudinal length.

[0060] For example, over the entire vertical extension (eg longitudinal length) of the fastening material free area, the distance (eg transverse width) may be at least 5 mm, or any other range mentioned above.

[0061] For example, over the entire vertical extension (e.g. longitudinal length) of the fastener, the distance (e.g. transverse width) can be at least 5 mm or any other range mentioned above. This helps to promote the area without fastening material to form a free edge portion from the outer edge of the fastener, which can be easily identified.

[0062] Furthermore, and as mentioned above, the area without fastening material may have a vertical extension (eg longitudinal length) of at least 20 mm. For example, the area without fastening material may have a vertical extension (eg longitudinal length) of at least 30 mm or at least 50 mm.

[0063] For example, the fastening material-free area may have a vertical extension (eg, longitudinal length) of no more than 200 mm, such as no more than 150 mm or no more than 100 mm. In some examples, the vertical extension (eg, longitudinal length) may be no greater than 70 mm.

[0064] For example, the vertical extension (eg longitudinal length) may be 30 mm to 70 mm, such as 40 mm to 50 mm.

[0065] The longitudinal length of the fastening material free area refers to any longitudinal length that may be measured in a direction parallel to the longitudinal axis.

[0066] For example, the vertical extension of the area without fastening material may correspond to the extension of the fastener in the vertical extension direction. For example, the longitudinal length of the area without fastening material may correspond to the length of the fastener.

[0067] The vertical extension (e.g. longitudinal length) of the area without fastening material can be, for example, greater than or substantially equal to the extension (e.g. longitudinal length) of the fastening area of ​​the fastener. Therefore, the force from pulling the area without fastening material can be distributed in an advantageous manner to the fastening area to be removed from the underlying material.

[0068] For example, the area without fastening material can be substantially rectangular. Therefore, the fastener can be substantially rectangular.

[0069] For example, the longitudinal length of the fastening area and / or the longitudinal length of the area without fastening material may be selected according to the longitudinal length of the side and / or second end portion to which the fastener is attached.

[0070] For example, it may be desirable that the longitudinal length of the fastening area is at least 50% of the longitudinal length of the side portion and / or the second end portion. For example, when the absorbent product is a belted product and the side portion is the first belt portion to which the fastener is attached, the longitudinal length of the fastening area may be at least 50% of the longitudinal length of the first belt portion.

[0071] In some embodiments, the base formed by the sheet material may protrude beyond the outer edge of the side and / or the second end portion of the disposable absorbent hygiene product. In such an embodiment, the area without fastening material may at least partially protrude beyond the outer edge of the side and / or the second end portion. In this way, the tactile and visual identification of the fastener may be further promoted.

[0072] In some variations, the fastening material-free area is located partially on the portion of the sheet-formed base that protrudes beyond the outer edge of the side portion and partially on the portion of the sheet-formed base that overlaps the side portion.

[0073] In some variations, the fastening material-free area may substantially correspond to the portion of the base formed by the sheet that protrudes beyond the outer edge of the side and / or second end portion. In other words, the fastening material-free area may extend over 100% of the area of ​​the base formed by the sheet that protrudes beyond the outer edge of the side and / or second end portion.

[0074] In some variations, the fastening material-free area is completely located on the portion of the base formed by the sheet that protrudes beyond the outer edge of the side and / or second end portion, and the fastening area is partially located on the portion of the base formed by the sheet that protrudes beyond the outer edge of the side and / or second end portion. For example, the fastening material-free area can extend over at least 30% of the area of ​​the base 200 formed by the sheet that protrudes beyond the outer edge of the side and / or second end portion, such as at least 50% or at least 70%.

[0075] For example, the base formed by the sheet material may protrude beyond the outer edge by a distance of at least 3 mm, such as at least 5 mm. For example, the base formed by the sheet material may protrude beyond the outer edge by a distance of between 3 mm and 15 mm, such as between 5 mm and 15 mm.

[0076] Thus, the wearer or caregiver may optionally grasp the fastening material-free area directly, rather than together with the side portions and / or the second end portion of the disposable absorbent hygiene product, when unfolding or adjusting the product.

[0077] The area without fastening material may have a color, shape or texture that is completely or partially different from the side and / or the second end portion of the disposable absorbent sanitary product. For example, when at least a portion of the area without fastening material protrudes beyond the outer edge of the side and / or the second end portion, the protruding portion may have a color, shape or texture that is completely or partially different from the rest of the fastener. Having a color, shape or texture that is different from the color, shape or texture of the side and / or the second end portion of the disposable absorbent sanitary product makes it easy for the wearer or caregiver to see the fastener, and this will trigger the wearer or caregiver to grasp the area without fastening material instead of the side and / or the second end portion.

[0078] The base formed by the sheet material may be free of fold lines. Thus, the area without fastening material will actually extend in the transverse direction of the product so as to be easily identifiable by the user. For example, the required bending stiffness of such an area without fastening material will be effective for tactile identification of fasteners. On the contrary, if the base formed by the sheet material is provided with fold lines, the base formed by the sheet material may tend to fold away from the user's fingers when searching for fasteners.

[0079] According to one exemplary embodiment, the fastening elements are hooks. That is, at least a plurality of discrete fastening elements comprising stems protruding from the upper surface of the base formed by the sheet of material are hooks.

[0080] "Hook" is intended to mean a hook component or surface projection of a hook-and-loop type fastener, which is adapted to be fastened to an area including a fiber annulus, referred to as an attachment area. The hook can have any shape. Examples of hooks include pins, such as straight pins, angled pins, curved pins, tapered pins, pins with limbs or multiple limbs, hooks, hooks with limbs or multiple limbs, mushroom-shaped projections, and palm tree-shaped projections. The hook can have any type of cross-section, such as circular, oval, square, rectangular, or polygonal. The hook can have a solid core. In a fastening portion, all hooks can have the same shape. Alternatively, a fastening portion can include hooks of several different shapes.

[0081] The fastener can be manufactured by extruding a polymer into a mold forming a base formed of sheet material with an integrally formed hook or pin-like protrusion, and optionally post-forming a mushroom-shaped head on the pin-like protrusion. The fastener can also be manufactured by extruding a polymer onto a base formed of sheet material to form a hook of a pin-like protrusion.

[0082] When manufacturing the fastener, the fastening material-free area may be free of hook or pin-like protrusions, or may be optionally melted in a second step. The attachment area with which the fastener is attached to the disposable absorbent hygiene product at least partially overlaps the fastening area. Thus, the fastening area at least partially overlaps the attachment area and the side and / or second end portion of the attachment fastener.

[0083] For example, the attachment area may overlap the entire fastening area. In other words, the fastening area will not extend beyond the side and / or second end portion to which the fastener is attached.

[0084] In another example, the fastening region may extend beyond the side and / or second end portion to which the fastener is attached, as long as the fastening region at least partially overlaps the attachment region and the side and / or second end portion.

[0085] Optionally, the attachment area with which the fastener is attached to the disposable absorbent hygiene product at least partially overlaps the fastening area and extends outside the fastening area into an area where the base formed by the sheet is free of the fastening elements but inside the edge of the base formed by the sheet.

[0086] When the product is unfolded after being removed from the packaging, by allowing the attachment area to protrude into the no fastener material area, when the fastener is removed from the material to which it is attached (e.g., the top sheet or back sheet of the absorbent sanitary product or any other material), the force is distributed in a beneficial manner. When the wearer or caregiver unfolds the product, they usually grasp it close to the fastener with their fingers. That is, the wearer / caregiver usually grasps the material close to the fastener, i.e. the side or the second end portion, and pulls the fastener via the side or the second end portion. The wearer / caregiver usually holds the rest of the product with the other hand. When the wearer / caregiver begins to pull the material close to the fastener, the base formed by the sheet material attached to the side or the second end portion by the attachment area and the no fastener area begin to move with the side or the second end portion as the wearer pulls the side or the second end portion away from the material to which the fastening area of ​​the fastener is attached. That is, as the wearer / caregiver pulls away the side or second end portion, the base formed by the sheet and the area without fastening material begin to bend slightly upward / away from the material to which the fastening area is attached. As the wearer / caregiver continues to pull the side or second end portion even further away from the material, a plurality of discrete fastening elements including the rods closest to the area without fastening material begin to release from the material to which they are attached, and as the wearer / caregiver pulls even further until the entire fastener is released from the material, other rods are also released. This is also applicable when adjusting the product.

[0087] The attachment area may be arranged at a distance from said outer edge of said side portion and / or said second end portion. This is advantageous in view of production requirements, for example for applying an adhesive in the attachment area.

[0088] For example, the attachment area may be arranged at a distance from the outer edge of the side and / or second end portion, wherein the distance does not exceed 5 mm. Thus, the portion of the side and / or second end portion that freely extends beyond the attachment area in the same direction as the fastening material-free area of ​​the fastener is relatively small. Thus, tactile identification of the fastener is facilitated, since the user may conclude that the small and possibly yielding edge of the side and / or second end portion is not suitable for gripping to remove the fastener from the connection with the underlying material, and instead chooses to grip the fastening material-free area of ​​the fastener (possibly together with the edge of the side and / or second end portion).

[0089] For example, the attachment area may be arranged at a distance from the outer edge of the side portion and / or the second end portion, wherein the distance does not exceed 3 mm.

[0090] For example, the attachment area may be arranged at a distance from the outer edge of the side and / or second end portion, wherein the distance is at least 2 mm smaller than the distance between the attachment area and the outer edge of the fastener (ie the outer edge of the area without fastening material).

[0091] For example, the fastener may be attached to the disposable absorbent hygiene product in the attachment area by adhesive, ultrasonic welding or heat sealing / welding or a combination thereof. The attachment material, i.e., adhesive or weld, may cover all or part of the attachment area, for example, the weld or adhesive may be applied in strips evenly or unevenly distributed over the attachment area.

[0092] The adhesive may be an adhesive suitable for application. For example, the adhesive may be a hot melt adhesive applied during product manufacture or an adhesive pre-applied on the fastener.

[0093] According to an exemplary embodiment, the fastener is attached to the disposable absorbent hygiene product in the attachment area by adhesive, welding or heat sealing or a combination thereof.

[0094] In some variations, the attachment area can extend into the area of ​​the base formed by the sheet without fastening elements. When the product is unfolded after being removed from the package, by having the attachment area protrude into the area without fastening material, the force is distributed in a beneficial manner when the fastener is removed from the material to which it is attached (e.g., the top sheet or back sheet of an absorbent hygiene product or any other material). When the wearer or caregiver unfolds the product, they usually grasp it close to the fastener with their fingers. That is, the wearer / caregiver usually grasps the material close to the fastener, i.e., the side or second end portion, and pulls the fastener via the side or second end portion.

[0095] For example, the attachment region may extend into a region of the sheet-formed base that is free of fastening elements but is inside the outer edge of the sheet-formed base.

[0096] According to an exemplary embodiment, the fastening area is arranged at a second distance from the second outer edge of the base formed by the sheet, and the second outer edge is arranged in the opposite direction of the first outer edge of the base formed by the sheet. For example, the fastening area can be arranged at a second distance from the second outer edge of the base formed by the sheet arranged in the second transverse direction (the second outer edge is arranged in the opposite direction of the first outer edge of the base formed by the sheet), thereby forming a second fastening material-free area on the base formed by the sheet. Although it may not be primarily intended that the fastener should be opened from the second outer edge side of the base formed by the sheet, providing a second fastening element-free area can enable the user to grasp the fastener at this second area in certain circumstances. This allows the wearer or caregiver to grasp either side of the fastener and still have the advantages as described above.

[0097] For example, the attachment area may extend into a second area where the base formed by the sheet material is free of the fastening elements but inside the second edge of the base formed by the sheet material. By having two opposite sides in a transverse direction, where the attachment area protrudes into two areas without fastening areas, the attachment area is larger than the fastening area in both transverse directions.

[0098] According to an exemplary embodiment, the fastening area is arranged at a third distance from a third outer edge of the base formed by the sheet arranged in the first longitudinal direction, forming a third area without fastening material on the base formed by the sheet. Similar to the second area described above, the attachment area can extend into a third area in which the base formed by the sheet is free of fastening elements but inside the third outer edge of the base formed by the sheet.

[0099] According to an exemplary embodiment, the fastening area is arranged at a fourth distance from a fourth outer edge of the base formed by the sheet arranged in the second longitudinal direction, forming a fourth area without fastening material on the base formed by the sheet. Similar to the second and / or third area as described above, the attachment area can extend into a fourth area, in which the base formed by the sheet is free of fastening elements, but inside the fourth outer edge of the base formed by the sheet.

[0100] According to an exemplary embodiment, the attachment area is arranged at a distance from the first outer edge and / or the second outer edge and / or the third outer edge and / or the fourth outer edge, and the distance is smaller than the first and / or the second and / or the third and / or the fourth distance between the fastening area and the corresponding outer edge. Alternatively, the attachment area can be up to the first outer edge and / or the second edge and / or the third outer edge and / or the fourth outer edge, but preferably does not protrude beyond the first outer edge and / or the second outer edge and / or the third outer edge and / or the fourth outer edge.

[0101] According to an exemplary embodiment, the second and / or third and / or fourth distance is 3-10 mm, in particular 3-6 mm or more in particular 3-4 mm.

[0102] The second and / or third and / or fourth distances may be smaller than the first distance, i.e., in some embodiments, smaller than the lateral width of the first fastening element-free area. Thus, when grasping the fastener to remove the fastener from the underlying material, the user is primarily encouraged to use the first fastening element-free area. For example, the second and / or third and / or fourth distances may be at least 2 mm smaller than the first distance.

[0103] The second outer edge, the third outer edge and the fourth outer edge of the fastener may be arranged not to protrude beyond the outer edge of the side and / or the second end portion. For example, as described above, the first outer edge of the fastener may be arranged to protrude beyond the first outer edge of the side and / or the second end portion, and the second outer edge, the third outer edge and the fourth outer edge may be arranged not to protrude beyond the outer edge of the side and / or the second end portion. Thus, the user is prompted to grip the first fastening element-free area to remove the fastener from the underlying material.

[0104] According to one exemplary embodiment, the first end portion is a rear region of the disposable absorbent hygiene product, the second end portion is a front region of the disposable absorbent hygiene product, and the central portion is a crotch region.

[0105] According to an exemplary embodiment, the base formed by the sheet protrudes beyond the outer edge of the side and / or the second end portion of the disposable absorbent sanitary product, and the attachment area is arranged at a distance from the outer edge of the side and / or the second end portion of the disposable absorbent sanitary product. For example, the fastening area can protrude beyond the outer edge of the side and / or the second end portion of the disposable absorbent sanitary product.

[0106] According to an exemplary embodiment, the disposable absorbent sanitary product is a belt-type product, and the side portions are a first belt portion and a second belt portion, which are used to be fixed to each other around the waist of the wearer of the product to form a belt with an outer surface, wherein the first belt portion has a free end, and the free end carries the fastener suitable for attachment to the outer surface of another of the belt portions.

[0107] According to an exemplary embodiment, the disposable absorbent sanitary product is a belt-type product, and the side portion is a first and a second belt portion, which are used to be fixed to each other around the waist of the wearer of the product to form a belt having an outer surface, wherein the first belt portion is suitable for being attached to the outer surface of another of the belt portions, and wherein the second end portion of the base includes the fastener for fixing the second end portion of the base to the belt portion, so that the product presents a pant-like shape, wherein the belt portion forms part of the waist portion of the pants.

[0108] According to an exemplary embodiment, the side parts are side panels, each side panel comprising said fastener and connecting the first end portion and the second end portion to each other, said fastener being adapted to be attached to a contact area on the second end portion when the product is worn. In this way, the absorbent hygiene product is an open absorbent product, a so-called all-in-one diaper.

[0109] According to an 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, and wherein the side portions on the first end portion are side panels each comprising the fastener and connecting the first end portion and the second end portion to each other, the fastener being adapted to be attached to the contact areas on the respective side portions of the second pair of side portions when the product is worn. In this way, the absorbent sanitary product is another type of open absorbent product, namely the so-called all-in-one diaper.

[0110] According to an exemplary embodiment, the fastener is arranged in the second end portion of the disposable absorbent sanitary product, where the top sheet and the back sheet are attached together at a bonding area, which at least partially overlaps the attachment area and extends outside the attachment area at least in the first transverse direction.

[0111] According to another exemplary embodiment, a disposable absorbent sanitary product is disclosed, the disposable absorbent sanitary product being a belt-type product, the belt-type product comprising a substrate having a first end portion and a second end portion and a central portion extending between the first end portion and the second end portion, the substrate having a body-facing surface intended to face the body of a wearer and a clothing-facing surface intended to face away from the body of the wearer, a longitudinal axis extending in the longitudinal direction and defining the longitudinal direction from the first end portion toward the second end portion and a transverse axis defining a transverse direction perpendicular to the longitudinal direction, the substrate comprising a liquid-permeable top sheet at the body-facing surface, a liquid-impermeable back sheet at the clothing-facing surface, and an absorbent core assembly comprising at least one absorbent core arranged between the top sheet and the back sheet, the disposable absorbent sanitary product also comprising a pair of side portions, the side portions being in the form of belt portions extending along the transverse direction on each side of the first end portion to fasten the absorbent sanitary product to the waist of the wearer, the disposable absorbent sanitary product comprising at least one fastener, the fastener being arranged on at least one of the belt portion and / or the second end portion of the disposable absorbent sanitary product to fasten The absorbent sanitary product is fastened to the waist of the wearer, the fastener comprising a base formed by a sheet, the base formed by the sheet having a substantially parallel upper surface and a lower surface, 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 to fasten the absorbent sanitary product to the waist of the wearer, the base formed by the sheet having a length in the longitudinal direction and a width in the transverse direction, and comprising at least one fastening area, the fastening area comprising one or more fastening material areas, the fastening material area comprising a plurality of discrete fastening elements, the fastening elements comprising The invention relates to a disposable absorbent sanitary product comprising a rod protruding from the upper surface of the base formed by the sheet, the fastening area being arranged at a certain distance from an outer edge of the base formed by the sheet arranged along the first transverse direction, a fastening material-free area being formed on the base formed by the sheet, the fastener being attached to the disposable absorbent sanitary product in an attachment area at least partially overlapping with the fastening area, wherein the fastening material-free area has a greater bending stiffness than the bending stiffness of the side and / or second end portion and / or wherein the distance is at least 5 mm, and wherein the fastening material-free area has an extension range of at least 20 mm in a direction perpendicular to the distance.

[0139] Various aspects of the present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments are shown. However, exemplary embodiments may take many different forms and should not be construed as limited to the details of the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness. Throughout the specification, the same reference numerals refer to the same elements.

[0140] For the purposes of this description, the terms "posterior", "anterior", "longitudinal", "inner", "outer", "exterior" and their derivatives refer to the same as in e.g. Figure 1 and Figure 4 . However, it should be understood that the exemplary embodiments may take various alternative orientations unless expressly specified to the contrary. It should also be understood that the examples shown in the drawings and described herein are merely exemplary embodiments. Therefore, unless otherwise expressly stated, the dimensions and other physical characteristics associated with the exemplary embodiments disclosed herein should not be considered limiting.

[0141] The present disclosure relates primarily to disposable absorbent hygiene products, which means products that are not intended to be laundered or otherwise restored or reused as absorbent products after use."Absorbent product" means a product that absorbs or is adapted to absorb body fluids such as urine and / or blood and / or contains solid excreta.

[0142] Figure 1 and Figure 2 A first embodiment of a disposable absorbent hygiene product 1 is shown, which is in the form of an open product, namely an open diaper.Open diapers are generally intended to be placed on the wearer while the wearer is lying down.

[0143] The open diaper 1 comprises a main part, namely a chassis 10, which has a body-facing surface intended to face the body of the wearer and a garment-facing surface intended to face away from the body of the wearer. The chassis 10 comprises a liquid-permeable topsheet 11 at the body-facing surface, a liquid-impermeable backsheet 12 at the garment-facing surface, and an absorbent assembly 30 disposed between the topsheet and the backsheet (see FIG. Figure 2).

[0144] exist Figure 1 and Figure 2 In the disposable absorbent sanitary product shown, the topsheet 11 and the backsheet 12 extend beyond the outer contour of the absorbent assembly 30 and are joined together outside the absorbent assembly contour using methods such as gluing or welding achieved by heat or ultrasound.

[0145] The chassis 10 has a first end portion 15 and a second end portion 14, wherein the second end portion 14 is a front end portion 14 intended to be located at the front (abdominal) waist region of the wearer, and the first end portion 15 is a rear end portion 15 intended to be located at the rear waist region of the wearer when the product is worn, i.e., the rear region. The 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 the front edge 4 of the front end portion 14 toward the rear edge 5 at the rear end portion 15 and a transverse direction T perpendicular to the longitudinal direction L.

[0146] The longitudinal side edges 2, 3 connect the front edge 4 and the rear edge 5 of the base body on mutually opposite sides of an imaginary longitudinal center line C, ie the longitudinal axis LO.

[0147] The open diaper 1 comprises a first pair of side portions 23, 24 which, in the embodiment shown, are in the form of side panels 23, 24. They are rear side panels 23 attached to the chassis 10 at the longitudinal side edges 2, 3, close to their rear edge 5.

[0148] The second pair of side portions 21, 22 in the form of front side panels 21, 22 are attached to the chassis 10 at the longitudinal side edges near the front edge 4. As an alternative, the open diaper 1 may not have a second pair of side portions at the front. That is, it may lack the second front side panels 21, 22.

[0149] The back side panels 23, 24 are each provided with a fastener 25, close to the outer edge 26 of the back side panels, i.e. the distal end of the back side panels opposite to the end attached to the chassis 10. The fasteners 25 are intended to be fastened on the garment-facing surface of the respective front side panels 21, 22 or on the garment-facing surface of the chassis 10 in order to fit the disposable absorbent sanitary product around the waist of the wearer.

[0150] Leg elastics 17 extending in a generally longitudinal manner may be attached to the chassis 10, for example sandwiched between the topsheet 11 and the backsheet 12 close to the longitudinal side edges 2, 3, to provide leg cuffs of the open diaper 1. Figure 1 and Figure 2As an alternative or in addition to the leg elastic members 17 in the exemplary embodiment of the present invention, the defined leg cuffs may include one or more elastic threads, elastic film strips or elastic foam strips and may be attached to the chassis 10 in a stretched state so as to exert a longitudinal contraction force on the open diaper 1.

[0151] The absorbent assembly 30 is arranged between the top sheet 11 and the back sheet 12. Figure 2 As shown. 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 diaper 1, the absorbent assembly 30 is arranged so that the longitudinal direction of the assembly is parallel to the longitudinal direction of the open diaper 1, the front end of the absorbent assembly faces the front end of the open diaper 1, and the rear end of the assembly faces the rear edge of the open diaper 1.

[0152] like Figure 1 and Figure 2 As shown, the absorbent assembly 30 includes two absorbent cores, a first absorbent core 31 and a second absorbent core 32, which are in a stacked relationship, that is, placed on top of each other so that both longitudinal ends of the second absorbent core are between the longitudinal ends of the first absorbent core, and are longitudinally located on the inner side of the longitudinal ends of the first absorbent core. However, the open diaper is not limited to having two cores. For example, it can have only one core or more than two cores.

[0153] The first absorbent core 31 is larger than the second absorbent core 32. The first absorbent core 31 comprises cellulose fibers, optionally mixed with superabsorbent polymers. The first absorbent core 31 extends over the entire longitudinal length of the absorbent assembly.

[0154] The second absorbent core 32 is located in the central portion 13. The second absorbent core 32 comprises a mixture of cellulose fibers and superabsorbent particles.

[0155] The flat surface area of ​​the second absorbent core 32 is smaller than the flat surface area of ​​the first absorbent core, for example, it may be less than 75%, such as less than 60% or less than 50%, such as 40 to 75% of the flat surface area of ​​the first absorbent core 31 .

[0156] exist Figure 1 and Figure 2 In the illustrated embodiment, the second absorbent core 32 is positioned between the first absorbent core 31 and the backsheet 12 on the garment-facing side of the first absorbent core 31. In alternative embodiments, the second absorbent core 32 can be positioned between the first absorbent core 31 and the topsheet 11 on the body-facing side of the absorbent core 31.

[0157] In a disposable absorbent sanitary product according to the present disclosure, in which the second absorbent core is positioned between the first absorbent core and the back sheet, the first absorbent core can partially act as a transfer layer for directing the fluid away from the top sheet and into the second absorbent core, and the main part of the liquid retention capacity is concentrated in the second absorbent core, thereby contributing to good liquid handling in the product.

[0158] The first absorbent core 31 and the second absorbent core 32 may be in direct contact with each other, which means that there is no additional layer of material, such as tissue or a nonwoven core wrap, between the two cores.

[0159] like Figure 1 and Figure 2 As shown, the outer contour of the absorbent assembly 30 can be hourglass-shaped, so that the width of the central region is narrower than the width of the front region and the rear region, respectively, wherein the width of the rear region and the front region can be equal or different. For example, the rear region can be wider than the front region.

[0160] In alternative embodiments, the outer contour of the absorbent assembly may be a different shape, such as rectangular or oblong.

[0161] like Figure 1 and Figure 2 As shown, the acquisition layer 16 may be sandwiched between the topsheet 11 and the absorbent assembly 30. Although the absorbent assembly 30 is intended to receive and retain large amounts of exudates (e.g., urine), it may be advantageous to include an acquisition layer between the topsheet 11 and the absorbent core assembly 30 to provide temporary acquisition of large amounts of liquid, as well as to provide a layer for distributing liquid away from the immediate impact site.

[0162] Figure 3 Shown in closed state Figure 1 and Figure 2 An open diaper as depicted in.

[0163] Figure 4 A second embodiment of a disposable absorbent hygiene product in the form of a belted product 100 is shown. A belted product generally comprises a belt and a base part. A belted product comprises a transverse belt connected to a front end portion or a rear end portion of the base part of the product. When such a belted product is applied, the belt is fixed around the waist of the wearer by means of fasteners in a first stage. In this type of product, the base part of the belted product is loosely suspended on the belt. The base part is then guided between the legs of the wearer and attached to the belt, wherein the belt comprises a fixing surface intended to be quickly adhered to a fixing member or fastening means (i.e. a second and / or third fastener) arranged on the base part by its free transverse edge.

[0164] Figure 4 and Figure 5Some components of the belted product 100 are schematically shown, wherein the belted product 100 is shown from the side intended to face the wearer when in use.

[0165] like Figure 4 As shown, the belted product 100 includes a base 110 and a waistband. 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.

[0166] Furthermore, the belted product 100 has a longitudinal direction L and a transverse direction T. In other words, the belted product has a length extension in the longitudinal direction L and a width extension in the transverse direction T. Furthermore, the base 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 base 110 defines a longitudinal direction L from a front edge 104 of the front end portion 114 toward a rear edge 105 at the rear end portion 115 and a transverse direction T perpendicular to the longitudinal direction.

[0167] The longitudinal side edges 102, 103 connect the front edge 104 and the rear edge 105 of the base 110 on mutually opposite sides of an imaginary longitudinal center line C (ie, the longitudinal axis LO).

[0168] The chassis 110 comprises a first covering layer 111 , ie a topsheet 111 , having a first surface intended to face towards the wearer in use and a second surface intended to face away from the wearer.

[0169] A pair of side portions in the form of a first belt portion 123 and a second belt portion 124 are attached to the base 110 such that the first belt portion 123 and the second belt portion 124 extend on each side of a first end portion 115 of the base for securing to each other around the waist of the wearer to form a belt having an outer surface. Thus, each of the first belt portion 123 and the second belt portion 124 is connected to the base 110 in 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 opposite longitudinal side edge 103. Typically, although not strictly required, the belt portions 123, 124 may be partially or completely elastic.

[0170] Each belt portion 123, 124 has an inner surface that faces toward the wearer during use and an outer (exterior) surface that faces away from the wearer during use. Figure 4In the belt-type product 100 shown, the belt portions (the first belt portion 123 and the second belt portion 124) extend in the transverse direction T of the belt-type product. The belt portions (the first belt portion 123 and the second belt portion 124) also extend in the longitudinal direction L and have a width. The width of the belt portion can be between 5 and 20 cm, for example, between 7 and 15 cm. The first belt portion 123 and the second belt portion 124 have the same length. In an alternative embodiment, one belt portion can be longer than the other. The combined length of the two belt portions is designed to reach around the waist of the wearer. In some embodiments, the two belt portions 123, 124 of the belt-type product 100 can be formed by only one piece of material, which extends across the entire rear end portion 115 in the transverse direction T and passes through the corresponding longitudinal side edges 102, 103 (not shown).

[0171] The first and second belt portions 123, 124 are attached to the base 110 such that the first and second belt portions 123, 124 each extend on each side of the first end portion 115 of the base for securing to each other 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 facing the wearer during use. The fastener 125 is adapted to be attached to the second belt portion 124 for securing the belt portions 123, 124 to each other around a wearer of the product. The fastener 125 is arranged proximate to an outer edge 126 of the belt, i.e., the distal end opposite to the end of the belt portion attached to the base 110.

[0172] In this example, as e.g. Figure 4 As shown, the first belt portion 123 has a free end 106, which carries a fastener 125 suitable for attaching to the outer surface of another belt portion (i.e., the second belt portion 124). In some examples, the outer surface of the second belt portion 124 can be provided with a mating fastening component (not shown) or it itself acts as a mating fastening component. In this example, the outer surface of the second belt portion 124 is used as a mating fastening component. Thus, the fastener 125 and the mating fastening component can be mechanically connected to form an interconnection between the first belt portion and the second belt portion for fixing to each other around the wearer of the absorbent hygiene product.

[0173] As mentioned above, the second end portion 114 of the base body 110 includes at least one additional fastening means. Figure 4In the embodiment of the invention, two fasteners 148, 149 are arranged on the second end portion 114 for fixing the second end portion 114 of the base body to the belt portions 123, 124, so that the product presents a trouser-like shape, wherein the belt portions 123, 124 form a part of the waist of the trousers. The second end portion 114 of the base body can be fixed 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 base body, i.e. the second end portion 114, comprises a fastening device (or a plurality of fastening devices), i.e. fasteners 148, 149, for fixing the front end portion of the base body to the belt.

[0174] Now go to Figure 5 , Figure 4 The belted product 100 in FIG. 1 is depicted in a state where the first belt portion 123 and the second belt portion 124 are folded over the top sheet 111 to form a folded belted configuration prior to use of the product. Thus, the first belt portion 123 is arranged on top of the second belt portion 124. Here, the belted product is shown in its folded belted configuration. The belted product is typically further folded before being arranged in a package (not shown).

[0175] like Figure 5 As shown, the second belt portion 124 is arranged to overlap with the base 110 of the product, and the first belt portion 123 is arranged to overlap with the second belt portion 124. In other words, the second belt portion 124 is arranged to overlap with the first end portion 115 (i.e., the rear end portion 115 of the base 110), and the first belt portion 123 is arranged to overlap with the second belt portion 124. To this end, 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 Figure 6 ).

[0176] The second belt portion 124 can be arranged to overlap the absorbent core assembly 131 of the product, and then the first belt portion 123 is arranged to overlap the second belt portion 124. Therefore, when the first belt portion 123 and the second belt portion 124 are folded on the top sheet 111 to form a folded belt configuration before using the product, the second belt portion 124 is arranged to overlap the absorbent core 131 of the product, and the first belt portion 123 is arranged to overlap the second belt portion 124 (not shown).

[0177] In addition, the second belt portion 124 can be releasably attached to the top sheet 111 by a destructible adhesive. In other words, when the first belt portion 123 and the second belt portion 124 are folded on the top sheet 111 to form a folded belt configuration before using the product, the second belt portion 124 is releasably attached to the top sheet 111 by a destructible adhesive (not shown).

[0178] 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, when the first belt portion 123 and the second belt portion 124 are folded over the top sheet 111 to form a folded belt configuration before using the product, the first belt portion 123 is releasably attached to the outer surface 124a of the second belt portion 124 by the breakable adhesive. Breakable adhesives are optional; however, they can help the belt portions remain in place during manufacturing.

[0179] The strap may be inelastic or partially elastic. A partially elastic strap is one in which some portion of the strap length has elastic properties, while some other portion of the strap length does not have elastic properties. In some design variations, one or both of the first strap portion 123 or the second strap portion 124 include an intermediate elastic region (not shown).

[0180] As mentioned above, the belted product 100 comprises a first covering layer, namely the topsheet 111, wherein the first covering layer comprises a first surface intended to face the wearer when the belted product 100 is in use.

[0181] exist Figure 4 and Figure 5 In the embodiment, fastening means 148, 149 (e.g. first fasteners 148 and second fasteners 149) are arranged on a side of the top sheet 111 intended to face the wearer when the belted product 100 is used. The fasteners 148, 149 are arranged in the front end portion 114 of the top sheet 111 at the respective longitudinal edges 102, 103, i.e. connected to the two front corners of the base body 110. The fastening means, i.e. the fasteners 148, 149 on the front end portion are intended to be detachably connected to the belt portions 123, 124 intended to face away from the wearer when the belted product 100 is applied to the wearer.

[0182] When the belted product 100 is applied to a wearer, the belt portions 123 and 124 (forming a belt) are first secured around the wearer's waist. The loosely suspended front end portion 114 of the belted product 100 is then guided between the wearer's legs, and then the fastening devices 148, 149 are secured to the belt portions 123 and 124 (i.e., the belt) on the wearer's stomach on the side of the belt that is oriented away from the wearer.

[0183] It is also possible to consider a belted product in which the belt is connected to the front end portion of the belted product. Such a product is applied to the wearer in the reverse manner, i.e. after the belt has been fastened around the wearer's waist, the loosely hanging rear end portion is guided between the wearer's legs and fastened to the belt at the back on the side of the belt oriented away from the wearer.

[0184] In order to improve the fit of the belted product 100, the longitudinal edges 102, 103 of the substrate 110 may be provided with leg elastics 117 arranged substantially along the longitudinal direction L of the product. The tasks of the leg elastics 117 include improving the fit of the product and making the belted product 100 more like a multi-purpose briefs / pants of fabric. The leg elastics 117 may include one or more elastic threads that have been connected to the top sheet by gluing, ultrasonic welding, etc. in a stretched state. Alternatively, the leg elastics 117 may include an elastic band-like material such as a foam material. The leg elastics 117 may be arranged on a side of the top sheet 111 that is intended to be facing away from the wearer when in use.

[0185] The rear end portion 115 or the front end portion 114 of the belt-type product 100 may also be provided with a so-called waist elastic 146 in the form of an elastic element arranged along the front edge 104 or the rear edge 105 of the belt-type product 100 so that the belt-type product 100 softly and flexibly surrounds the waist of the wearer. Figure 4 In the embodiment, only the front end portion 114 of the belt-type product 100 is provided with a waist elastic 146. The waist elastic 146 comprises a thin strip of elastic foam material, which is attached to the side of the top sheet intended to face away from the wearer by adhesive. The waist elastic 146 is applied in a stretched state to achieve a retaining conformity force that stretches the belt-type product 100 around the waist of the wearer. When the fasteners 148, 149 are fastened to the belt, it is appropriate that the waist elastic 146 is tensioned in the transverse direction T of the belt-type product 100 so that the front end portion 114 has a smooth configuration on the stomach of the wearer in use.

[0186] The belted product 100 comprises a second covering layer 112 arranged on the side of the first top sheet which is intended to face away from the wearer when in use. The second covering layer 112 is a so-called backsheet 112. The backsheet has the same extension in the L / T plane as the top sheet. The backsheet 112 is generally substantially liquid-impermeable, but other types of covering layers may also be used instead. Typically, although not strictly necessary, the topsheet and backsheet of the belted product 100 have an hourglass shape. Other shapes, such as a rectangular shape, may also be considered in other design variations.

[0187] The top sheet 111 and the back sheet 112 can be joined to each other in several different ways. Examples of joining methods are gluing, heat fusion, ultrasonic welding, etc. For a belt-type product 100 comprising a top sheet 111 and a substantially liquid-impermeable back sheet 112, it is appropriate to arrange the above-mentioned leg elastics 117 and waist elastics 146 between the top sheet 111 and the back sheet 112. In a belt-type product 100, the top sheet 111 can have a low absorption capacity, wherein smaller body secretions, such as occasional drops of urine, such as initially secreted menstrual fluid, etc., can be absorbed.

[0188] The belted product 100 has an absorbent core 131 disposed between a top sheet 111 and a back sheet 112 (see FIG. Figure 5 ) form of absorbent assembly 130. According to the top sheet 111 of the belt-type product of this example, it can be liquid permeable. The absorbent core 131 has a profile substantially the same as the top sheet 111 and the back sheet 112, but has a smaller surface. Therefore, the top sheet 111 and the back sheet 112 extend to the edge of the absorbent core 131 outside along the entire periphery of the absorbent core 131. Similar to the top sheet 111 and the back sheet 112, the absorbent core 131 can have a front end and a rear end portion and a narrower crotch portion between the end portions. According to the belt-type product 100 of this example, it is related to a diaper intended to be used by an incontinent adult or a child who has not yet become incontinent. When using the belt-type product including the absorbent core 131, the front portion and the front end portion of the crotch portion are mainly used as the receiving area of ​​urine, and the rear portion and the rear end portion of the crotch portion are mainly used as the receiving area of ​​feces. The top sheet 111 and the back sheet 112 are connected to each other along the entire periphery of the absorbent assembly 130 outside the absorbent assembly 130.

[0189] Now go to Figure 6 , Figure 6 Shows the combination Figure 4 and Figure 5 An enlarged view of one section of the strap of the depicted product, namely the first strap portion 123 and the second strap portion 124. Figure 6 1 is an exploded view of the belt portion to facilitate illustrating the components of those components. As described above, the first belt portion 123 of the waistband is intended to be interconnected to the second belt portion 124 by fasteners 125 for securing each other around the wearer of the belted absorbent hygiene product. In addition, as described with respect to Figure 4 and Figure 5 As described, the second end portion 114 of the base 110 includes fastening means, namely fasteners 148, 149, for fixing the second end portion 114 of the base to the belt portion so that the product presents a trouser-like shape, wherein the belt portion forms a part of the waist of the trousers. The fasteners 148, 149 are two separate fasteners, such as Figure 4 and Figure 5However, it can also be provided as an extended piece of the fastener spanning the length of the second end portion as seen in the transverse direction T. The second end portion 114 of the base body can be fixed to either of the belt portions 123, 124. Typically, the second end portion 114 of the base body 110 can be fixed to both belt portions, i.e., to Figure 6 Outer surfaces 123a, 124a are shown.

[0190] Furthermore, in all of the exemplary embodiments described herein in conjunction with the belted product 100, as well as in other possible exemplary embodiments, the portion of either the first belt portion and the second belt portion that extends 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 hereby permanently attached to the first end portion 115 of the base. Similarly, the end portion of the second belt portion 124 is hereby permanently attached to the first end portion 115 of the base.

[0191] The belt parts 123, 124 can be made of a layer of fiber material, for example, made of nonwovens (such as spunbond nonwovens). In another example, the belt parts 123, 124 can be a flexible laminate of at least two layers of fiber materials combined with a bonding pattern provided by, for example, ultrasound, laser and / or heat. If it is a flexible laminate, at least some of the fibers in the fiber material layer should be meltable by this bonding technology. As an alternative, the laminate can include at least three fiber material layers. An outer layer intended to form the outside of the belt is a fiber material suitable for use as a fastener 148, 149 on the front 114. Examples of nonwoven materials are spunbond, meltblown, combed bonding materials, etc. The middle layer can be a fiber material with relatively high tear strength, such as a spunbond or meltblown material containing continuous filaments. Another outer layer of the inner layer facing the wearer for forming the belt can be a soft and skin-friendly fiber material. Examples of suitable materials are spunbond and meltblown materials, combed bonding materials, etc. Examples of polymeric materials used in different fiber 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 40gsm and about 150gsm, for example, between about 60gsm and about 120gsm, and specifically between about 75gsm and about 105gsm. One or more layers of the laminate can be wrinkled. For example, the outer layer of the receiving material intended to be used as a fastening device, particularly as a loop material of a hook-and-loop type fastener, is wrinkled. By wrinkling, the loop function of the material is improved.

[0192] As mentioned above, belted products are typically disposable absorbent hygiene products such as diapers and incontinence guards.

[0193] Figure 1-6 Both exemplary embodiments shown in comprise a topsheet 11 , 111 , a backsheet 12 , 112 as described, and an absorbent core assembly 30 , 130 having at least one absorbent core 31 , 32 , 131 therebetween.

[0194] The topsheet in both embodiments is a liquid permeable topsheet 11, 111 arranged at the body-facing side of the disposable absorbent sanitary product. Suitable materials for the topsheet are well known in the field of disposable absorbent sanitary products, and for the purpose of this disclosure, any material known for use as a topsheet material may be used, including but not limited to nonwoven materials and perforated polymer films.

[0195] The topsheet 11, 111 suitably has sufficient fluid permeability to allow discharged body fluids such as urine to penetrate through the thickness of the topsheet 11, 111. In addition, the topsheet 11 is suitably made of a material that is compliant and soft to the wearer's skin.

[0196] The topsheet 11 , 111 may be made of various web materials, such as woven and nonwoven webs, perforated films, open-cell foams, or combinations or laminates of the above materials.

[0197] In the context of the present disclosure, "nonwoven" is a sheet, web or mat of fibers of directional or random orientation combined by friction and / or cohesion and / or adhesion, excluding paper and combined yarns or filaments combined by weaving, knitting, tufting, stitching or felting by wet grinding, whether or not additionally needled. The fiber can be of natural or artificial origin, and can be staple or continuous filament or formed in situ. The diameter range of commercially available fibers is less than about 0.001 mm to greater than about 0.2 mm, and they have several different forms: staple fibers (called cotton wool fibers, or short-cut fibers), continuous single fibers (filaments or monofilaments), untwisted continuous filament bundles (tows) and twisted continuous filament bundles (yarns). Nonwoven fabrics can be formed by many methods, such as meltblowing, spunbonding, solvent spinning, electrospinning and combing.

[0198] The nonwoven material suitable as top sheet can be made of synthetic fibers such as polyester or polypropylene, or natural fibers such as cotton fibers. Also a mixture of synthetic fibers and natural fibers can be used.

[0199] The nonwoven material for top sheet 11,111 can be for example made of spunbond, spunbond / spunbond composite material or spunbond / meltblown composite material, for example SMS (spunbond / meltblown / spunbond), SSMS, SSMMS, SMMS, nonwoven material of polypropylene or bicomponent fiber of polypropylene and polyethylene, or made of the combination of these materials. Top sheet 11 can also have elastic properties.

[0200] The top sheet 11, 111 can be hydrophilic in order to improve the tendency of urine to penetrate the top sheet into the underlying structure. Methods for hydrophilizing nonwoven materials are known and include coating the nonwoven material with a hydrophilic coating, for example by applying a surfactant coating; by applying a hydrophilic monomer complex and a free radical polymerization initiator to the nonwoven and then 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).

[0201] The surfactant coating can be obtained, for example, by applying the surfactant complex to the nonwoven material by any suitable means, including spraying, slot coating, kiss roll coating and / or immersing the material in a bath containing the surfactant. The hydrophilization treatment can be performed in-line during the assembly of the absorbent hygiene product, or can be performed separately, and the top sheet can then be delivered to the disposable absorbent hygiene product manufacturing plant as a ready-to-use roll.

[0202] The basis weight of the topsheet material can be from 8 g / m 2 Up to 20g / m 2 , for example from 12g / m 2 Up to 17g / m 2 However, the present disclosure is not limited to topsheet materials having only this basis weight.

[0203] The backsheet 12, 112 of both embodiments is arranged on the garment-facing side of the disposable absorbent sanitary product. Materials suitable as backsheets are well known in the field of disposable absorbent sanitary products. The backsheet 12, 112 prevents exudates absorbed by the absorbent assembly from soiling other external products that may contact the disposable absorbent sanitary product, such as bed sheets and underwear. The backsheet 12, 112 can be substantially impermeable to liquids, such as urine.

[0204] The backsheet may be substantially liquid impermeable yet breathable, ie, gas permeable, meaning that water vapor, air and other gases can pass through the backsheet 12, 112 while being substantially liquid impermeable.

[0205] For purposes of this disclosure, any material commonly known for use as a backsheet material may 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.

[0206] The backsheet may comprise one or more layers of material. For example, the backsheet may be a laminate of a liquid-impermeable polymer film towards the absorbent assembly and a nonwoven towards the garment side to provide a soft feel of fabric to the outer surface of the disposable absorbent hygiene product.

[0207] It is also contemplated that the backsheet may be made of or otherwise include a fully or partially elastic material to impart a better fit to the product when in use.

[0208] The absorbent assembly 30,130 of two examples can all comprise one or more absorbent cores.The core can be made of one or more layers of cellulose fluff pulp.Cellulose fluff pulp can be mixed with the fiber or particle of high absorbent polymer material (so-called super absorbent polymer), and its type is to chemically combine a large amount of fluid when forming fluid to keep gel when absorbing.The absorbent core can also comprise the high absorbent polymer material that is arranged in the layer inside the absorbent core or is connected to one or more surfaces of the absorbent core.The absorbent core can also comprise other components for improving the performance of the absorbent core.The example of these components is adhesive fiber, various types of fluid dispersion layer or fiber, dimensionally stable component, reinforcing fiber etc.

[0209] Superabsorbent polymers are well known in the absorbent product field and are used to help improve the absorbent properties of such products. Superabsorbent polymers are composed of water-swellable and water-insoluble polymers that are capable of absorbing large amounts of fluid when forming a hydrogel, for example, capable of absorbing at least 5 times their weight of a 0.9% saline solution as measured according to method NSWP 241.0.R2 (15). Superabsorbent polymers for use in accordance with the present disclosure may be inorganic or organic cross-linked hydrophilic polymers, such as polyvinyl alcohol, polyethylene oxide, cross-linked starch, guar gum, xanthan gum, cross-linked polyacrylates, and the like. The polymers may be in the form of, for example, powders, granules, particulates, films, foams, and fibers. Upon contact with fluid, these superabsorbent polymers swell by absorbing the fluid into their structure. Typically, superabsorbent polymers can quickly absorb fluid introduced into such products, and can retain such fluid to prevent leakage and help provide a dry feel even after the introduction of fluid.

[0210] The type of superabsorbent polymer used in the absorbent assembly of the embodiments discussed herein can be the same or can vary within the assembly. For example, a superabsorbent polymer with a first set of properties can be used in the front and rear regions of the absorbent assembly, or in a first absorbent core, and a superabsorbent polymer with a second set of properties can be used in the center region of the absorbent assembly, or in a second absorbent core. The properties mentioned in this section are, for example, centrifuge retention capacity (CRC), absorbency under load (AUL), and / or gel layer permeability (GLP).

[0211] The acquisition layer is mentioned with respect to open diapers, but can also be used in belt-type products. Materials suitable as acquisition layers (also referred to as transfer layers in the art) or ADLs (acquisition and distribution layers) are well known in the field of disposable absorbent sanitary products, and for the purposes of this disclosure, any material known to those skilled in the art as being useful as an acquisition layer can be used. The acquisition layer can be, for example, in the form of 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 suitable for quickly receiving and temporarily storing discharged liquid before the discharged liquid 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 with fluff, wood pulp, where the fluff fibers are dispersed into a fast-moving air stream and condensed onto a moving screen by means of pressure and vacuum. The acquisition layer can preferably be an air-through bonded nonwoven of polyester fibers.

[0212] The term "nonwoven" refers to Figure 1-6 The different parts of the disposable absorbent product disclosed in the invention, such as the top sheet, the back sheet and / or the side, which are located between the paper and paperboard group on the one hand and the fabric group on the other hand in terms of performance. Regarding nonwovens, a large number of extremely different production methods are used, such as air-laid, wet-laid, spunlace, spunbond, melt-blown technology, etc. The fibers can be in the form of circular fibers or prefabricated fibers with circular lengths, such as the form of synthetic fibers or staple fibers produced in situ. Alternatively, they can be made of natural fibers or of a blend of synthetic fibers and natural fibers.

[0213] Other components commonly used in disposable absorbent hygiene products that are shown but not described in the drawings of the present disclosure may be used in disposable absorbent hygiene products according to the present disclosure. For example, raised elastic members, commonly referred to as standing gathers, may be attached to the top sheet.

[0214] A wetness indicator, such as a material that changes its color when in contact with urine, can be included in a disposable absorbent hygiene product, such as disposed between the absorbent assembly and the backsheet and visible through the backsheet, such as to indicate whether a wetting event has occurred.

[0215] Figure 1-6 Both exemplary embodiments of disposable absorbent hygiene products shown include fasteners to secure the product to a wearer.

[0216] exist Figure 1-3 In the embodiment, two fasteners 25 are attached to the side panels 23, 24 of the open diaper 1. There is one fastener for each side panel. Figure 4-6In the embodiment of the present invention, one fastener 125 is attached to the first belt portion 123 of the belt-type 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 other fasteners 148, 149 are attached to the top sheet at the second end portion 114 (i.e., the front of the absorbent product).

[0217] The fasteners 125, 148, 149 used in the belted product 100 may all be of the same design, or they may be different. The fasteners 25 used in the open diaper 1 may all be of the same design, or they may be different.

[0218] A fastener will now be described in more detail and in Figure 7-13 The exemplary embodiment is shown in FIG. Figures 7 to 11 The fasteners shown are illustrated as being arranged in Figures 4 to 6 The fastener 125 on the first belt portion 123 of the belt-type product 100 in FIG. However, the fastener described may also be the following fasteners 148 , 149 : it can be attached to the top sheet 111 on the front 114 of the belt-type product 100 or to the corresponding side panels 23 , 24 of the open diaper 1 .

[0219] Figure 7 A first exemplary embodiment of a fastener 125 is shown, which is attached to Figure 4-6 The shape of the fastener 125 is rectangular, but the fastener is not limited to this shape. The fastener can have a square, circular, hexagonal, etc. shape.

[0220] The fastener 125 includes a base 200 formed of a sheet of material having generally parallel upper and lower surfaces 201, 202 (see also Figure 7a and Figure 7b ). The lower surface 202 of the base 200 formed of the sheet is attached to the belt portion 123. The base 200 formed of the sheet has a width W200 in the transverse direction T defined by the first outer edge 204 and the second outer edge 205, and has a length L200 in the longitudinal direction L of the belt diaper defined by the third and fourth outer edges 206, 207.

[0221] The sheet-formed base 200 has a fastening region 203 comprising a fastening material region 203 comprising a plurality of discrete fastening elements comprising rods (not explicitly shown) protruding over the entire region from the upper surface 201 of the sheet-formed base. Figure 8 and Figure 8aAs shown, the fastening area 203 includes several fastening material areas, here exemplified as three fastening material areas 203a, 203b, 203c, the fastening material area includes a plurality of discrete fastening elements, the fastening elements include rods protruding from the upper surface 201 of the base formed by the sheet. Therefore, the fastening area 203 is an area covering all three fastening material areas 203a, 203b, 203c, that is, including the space between the three fastening material areas 203a, 203b, 203c.

[0222] Figure 7 Shows Figure 4 123, wherein the fastener 125 is arranged near the outer edge 126 of the belt 123. When opening the belt, such as when the belt-type product is in a folded belt configuration before using the product, or when adjusting or removing the product on the wearer, the wearer or caregiver can grasp the end of the belt portion and pull.

[0223] like Figure 7 and Figure 7a As shown ( Figure 7a Shows Figure 7 AA in the cross section), the fastening area 203 is arranged at a first distance D1 from the first outer edge 204 of the base 200 formed by the sheet material, arranged in the first transverse direction, forming an area 208, that is, a first fastening material-free area 208 arranged on the base 200 formed by the sheet material. The first transverse direction is the direction away from the longitudinal axis when the absorbent product is in its unfolded state (for belt-type products, see Figure 4 , for open diapers see Figure 1 ).

[0224] The fastening material free region 208 may have a greater bending stiffness than the bending stiffness of the strap 123 where the fasteners 125 are arranged.

[0225] For example, the fastening material free area 208 may have a bending stiffness that is at least 15% greater than the bending stiffness of the strap 123, such as at least 20% greater.

[0226] The difference in stiffness can be such that a person grasping fastener 125 by approaching his / her hand toward outer edge 126 of strap 123 will be able to easily identify and grasp region 208 devoid of fastening material rather than the outermost end of strap 123. For example, the outermost end of strap 123 may yield more easily under the hand of the user, thereby making relatively stiff region 208 devoid of fastening material of fastener 125 easier to grasp.

[0227] Therefore, the bending stiffness of the fastening material free region 208 may be selected in view of the bending stiffness of the strap.

[0228] For example, in a Figure 7 to Figure 7b In the belt-and-belt product exemplified in FIG. 1 , the belt 123 may have a bending stiffness of at least 30 mgf, such as at least 35 mgf.

[0229] For example, the fastening material-free area may be selected to be at least 40 mgf or at least 45 mgf.

[0230] Thus, in one example, the bending stiffness of the strap 123 may be at least 35 mgf, and the bending stiffness of the fastening material free region 208 may be at least 40 mgf, such as at least 45 mgf.

[0231] For example, the belt may be a suitable belt material, such as the single layer material or laminate material mentioned above, having a basis weight of about 60-80 gsm and a bending stiffness of about 35-40 mgf.

[0232] The fasteners may be fastening materials such as hook materials, wherein the fastening material free area (eg the base formed by the sheet) may be a material as described above, for example comprising a nonwoven material having a basis weight of 50-60 gsm and a bending stiffness of about 45-55 mgf.

[0233] The fastening material free area 208 may have a transverse width D1 of at least 5 mm. Thus, a user may grip the fastening material free area when removing the fastener from connection with the underlying material.

[0234] For example, the lateral width may be at least 10 mm. In this way, the gripping of the area without fastening material may be further facilitated. For example, the lateral width may be 5 to 15 mm, or 10 to 15 mm.

[0235] Furthermore, and as mentioned above, the fastening material free areas 208, 209 may have a longitudinal length L1 of at least 20 mm. For example, the fastening material free areas may have a longitudinal length of at least 30 mm or at least 50 mm.

[0236] The longitudinal length of the fastening material-free area refers to the maximum longitudinal length that can be measured in a direction parallel to the longitudinal axis.

[0237] As illustrated in the embodiment of the figures, the transverse width D1 of the fastening material free region 208 may be substantially constant over the length L200 of the base 200 formed of the sheet of material.

[0238] For example, the fastening material-free area 208 may be substantially rectangular. For example, as in the embodiment of the figures, this may be preferred when the fastener 125 is substantially rectangular.

[0239] The longitudinal length L208 of the no fastening material area 208 may be, for example, greater than or substantially equal to the longitudinal length of the fastening area 203 of the fastener 124. Thus, the force from pulling the no fastening material area 208 may be distributed in an advantageous manner to the fastening area 203 to be removed from the underlying material.

[0240] The longitudinal length of the fastening region 203 and / or the longitudinal length L208 of the fastening material free region 208 may be selected in view of the longitudinal length of the strap 123 to which the fastener is attached.

[0241] For example, it may be desirable for the longitudinal length of the fastening region 203 to be at least 50% of the longitudinal length of the strap 123 .

[0242] In some variations, the longitudinal length L200 of the sheet-formed base 200 may be substantially similar to the longitudinal length of the strap 123 .

[0243] In other variations, as shown in the figures, the longitudinal length L200 is less than the longitudinal length of the strap 123. For example, the longitudinal length L200 of the base 200 formed of the sheet of fastener 125 may be at least 50% of the longitudinal length of the strap 123.

[0244] As illustrated in the embodiment of the drawings, the sheet-formed base 200 may be free of fold lines. A "fold line" refers to any line in the sheet-formed base that is or has been folded so as to imply a higher tendency of the sheet-formed base 200 to fold along the fold line. Thus, when the sheet-formed base 200 is free of fold lines, it will lack any tendency to fold in either direction, and thus the yield resistance felt when grasping the fastener is substantially derived from the inherent bending stiffness of the material of the fastener 125 attached to the strap 123 via the attachment area 212.

[0245] In some embodiments, where the fastener can be initially folded into the transport configuration, the sheet-formed base 200 can possibly include a fold line in an area outside the fastening area but on another side than the area without fastening material. Thus, at least in the area without fastening material 208, and optionally in the fastening area 203, the sheet-formed base 200 has no fold line.

[0246] Thus, the fastener may be such that at least the area without fastening material exhibits the same bending stiffness regardless of the orientation in which the bending stiffness is measured, ie, the area without fastening material exhibits a uniform stiffness.

[0247] Therefore, the bending stiffness of the material in the no fastening material region 208 will be substantially related to the manner in which the fastener 125 can be tactilely identified.

[0248] For example, and if Figure 7 to Figure 7aAs shown, the attachment area 212 may be arranged at a distance E1 from the outer edge 126 of the strap 123. This is advantageous in view of production requirements, for example for applying adhesive in the attachment area 212.

[0249] For example, the attachment area may be arranged at a distance E1 from an outer edge of the side portion and / or the second end portion, wherein the distance is not greater than 5 mm.

[0250] Thus, the portion of the strap 123 that freely extends beyond the attachment area 212 in the same transverse direction as the fastening material-free area 203 of the fastener 125 is relatively small. Thus, tactile identification of the fastener 125 is facilitated, as the user can conclude that the small, yielding edge of the strap 123 that protrudes beyond the attachment area 212 is not suitable for gripping in order to remove the fastener 125 from connection with the underlying material. Instead, the user may choose to grip the fastening material-free area 208 of the fastener 125. It should be appreciated that in situations such as Figure 7 and Figure 7a In the illustrated embodiment, when grasping the area without fastening material 208, the user will grasp the area without fastening material 208 together with the strap 123 to which the fastener 125 is attached.

[0251] exist Figure 7 and Figure 7a In the example of FIG. 1 , the fastening area 203 is also arranged at a second distance D2 from a second outer edge 205 of the base 200 formed of the sheet material arranged along the second transverse direction, thereby forming a second fastening material-free area 209 on the base 200 formed of the sheet material, wherein the second outer edge 205 is arranged in a direction opposite to the first outer edge 204 of the base 200 formed of the sheet material. The second transverse direction T is the direction toward the longitudinal axis (for belt-type products, see Figure 4 , for open diapers see Figure 1 ).

[0252] In another example, the second distance D2 may be omitted and the fastening region 203 extends all the way from the second outer edge 205 of the base 200 formed of a sheet of material.

[0253] For example, Figure 7 and Figure 7a As shown, the first distance D1 may be greater than the second distance D2. Thus, grasping of the fastener is facilitated at the first fastening material-free region 208 adjacent the outer lateral edge of the belt.

[0254] In this example, the fastening area 203 is arranged in the entire longitudinal direction L of the base 200 formed of the sheet material. Figure 7 and Figure 7b As shown, Figure 7b Shows Figure 7That is, the fastening region extends between the third outer edge 206 and the fourth outer edge 207 of the base 200 formed of the sheet material.

[0255] As in the example shown, the longitudinal length L200 of the fastener 125 may be less than the side and / or second end portions (ie, Figure 7 123). Thus, the strap extends from the attachment area 212 in a direction beyond the third edge 206 of the fastener 125 by more than a distance E3, and extends from the attachment area 212 by more than a distance E4 beyond the fourth edge 207 of the fastener 125. The longitudinal length L200 of the fastener 125 may, for example, be greater than 50% of the longitudinal length of the strap 123. Optionally, the distances E3, E4 between the attachment area 212 and the respective outer edges of the strap may be no greater than 5 mm.

[0256] Figure 8 , 8a A second alternative embodiment of the fastener is shown in Figures 8b, wherein the strap portion 123 and the fastener 125 have the same Figure 7 , 7a Same design as in 7b, except that the fastening area 203 comprises several areas of fastening material. Figure 8a Shows Figure 8 The cross section AA in Figure 8b Shows Figure 8 The cross section BB in Figure 8 and Figure 8a As shown, the fastening area 203 is illustrated as the total area of ​​three fastening material areas 203a, 203b, 203c, the fastening material comprising a plurality of discrete fastening elements, the fastening elements comprising rods protruding from the upper surface 201 of the base 200 formed of the sheet. Therefore, the fastening area 203 is an area covering all three fastening material areas 203a, 203b, 203c. That is, in the transverse direction, this area is defined by the outer edges of the first area 203a and the third area 203c. Other features are the same as above with respect to Figure 7-7b The same as described above and the same reference numerals are used, so no further description will be given. In addition to the fastening material areas 203a, 203b, 203c comprising a plurality of discrete fastening elements, an adhesive may be arranged between the three fastening material areas 203a, 203b, 203c on the upper surface 201 of the base 200 formed of a sheet. Thus, the adhesive may increase the fastening force.

[0257] Despite Figure 8 , Figure 8a and Figure 8b In the embodiment, the first distance D1 is shown to be approximately equal to the second distance D2, but it should be understood that the first distance D1 may alternatively be greater than the second distance D2, such as in combination with Figure 7 , Figure 7a and Figure 7b As shown and described.

[0258] The fastening area 203 is not limited to having only one fastening material area, such as Figure 7 , 7a and 7b, or three fastening material areas, such as Figure 8 , 8a 8b, it may have two or more areas of fastening material.

[0259] Fig. 9 , 9a A third alternative embodiment of the fastener is shown in Figures 9b, wherein the strap portion 123 and the fastener 125 have the same Figure 7 , 7a Same design as in 7b, except Figure 7b The fastening area 203 in the cross section BB in FIG. The other features are the same and use the same reference numerals and will therefore not be described again. Figure 9a Shows Fig. 9 The cross section AA in Figure 9b Shows Fig. 9 Cross section BB in. Fig. 9 and Figure 9b In addition to the first distance D1 and the second distance D2, Figure 7 and Figure 7a Described in and also in Figure 9a In addition to the corresponding first and second fastening material-free areas 208, 209 shown in the figure, the fastening area 203 can also be arranged at a third distance D3 from the third outer edge 206 of the base 200 formed by the sheet material and arranged in the first longitudinal direction, thereby forming a third fastening material-free area 210 on the base 200 formed by the sheet material. The fastening area 203 can also be arranged at a fourth distance D4 from the fourth outer edge 207 of the base formed by the sheet material and arranged in the second longitudinal direction, thereby forming a fourth fastening material-free area 211 on the base 200 formed by the sheet material. In other words, Fig. 9 A fastener 125 is shown in which the fastening region 203 is surrounded by a larger fastening material-free region composed of all four fastening material-free regions 208 , 209 , 210 , 211 combined.

[0260] Despite Fig. 9 , Figure 9a and Figure 9b In the embodiment, the first distance D1 is shown to be approximately equal to the second distance D2, but it should be understood that the first distance D1 may alternatively be greater than the second distance D2, such as in combination with Figure 7 , Figure 7a and Figure 7bAs shown and described.

[0261] As an alternative, not shown, the fastening area 203 may be arranged only at a first distance from one outer edge of the base formed by the sheet material arranged in the first transverse direction, thereby forming a fastening material-free area on the base formed by the sheet material. For example, when the absorbent product is in its unfolded state, the first transverse direction may be a direction away from the longitudinal axis (see Figure 4 ). Thus, on all other sides, the fastening material may extend to the outer edge of the base formed by the sheet material.

[0262] Figure 7a and Figure 7b The fastener 125 attached to the disposable absorbent hygiene product in the attachment area 212 is shown, the attachment area 212 overlaps with the fastening area 203 and extends beyond the area of ​​the fastening area 203, into the area where the base 200 formed by the sheet material is free of fastening elements 208, 209 but inside the outer edges 204, 205 of the base 200 formed by the sheet material. Therefore, the attachment area 212 does not protrude beyond the outer contour of the fastener 125. The attachment area 212 is the area where the fastener is attached to the underlying material by, for example, adhesive, heat sealing or welding or a combination thereof. The adhesive, heat sealing or weld seam achieved by welding can be arranged on the entire attachment area, i.e. covering the entire attachment area or distributed over this area, as long as the fastener is attached in an area free of fastening elements 208, 209 but inside its outer edges 204, 205.

[0263] exist Figure 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 ).exist Figure 7a 2 shows that the length W212 of the attachment area 212 is longer than the length W203 of the fastening area 203 in the transverse direction. Figure 7b , the attachment area 112 overlaps the entire fastening area except for a small area along the third and fourth outer edges 206, 207, because it is not desirable to have adhesive outside the fastener. Alternatively, the attachment area can be arranged all the way to the third and fourth outer edges 206, 207. Therefore, the area of ​​the attachment area 212 is larger than the area of ​​the fastening area 203.

[0264] By making the attachment area 112 larger than the fastening area 203, the forces will be distributed in a beneficial manner and the risk of the fastener tearing off the base or the belt is reduced. This is particularly true when the attachment area 212 extends into the first fastener-free area 208, which is in a direction away from the longitudinal direction when the product is in its unfolded state and in the direction in which the wearer or caregiver typically grasps the fastener with his / her fingers at the outer end of the first belt portion 123 when the product is unfolded or adjusted on the wearer. When the wearer or caregiver begins to pull on the outer end of the first belt portion 123, the base 200 formed by the sheet material attached to the first belt portion 123 by the attachment area 212 and the fastening material-free area 208 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.

[0265] That is, as the wearer or caregiver pulls the strap portion 123 away, the base 200 formed of the sheet material and the no fastening material area 208 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 strap portion 123 even further away from the material, multiple discrete fastening elements including the rods closest to the no fastening material area 208 begin to release from the material to which they are attached, and other rods are released as the wearer or caregiver pulls even further until the entire fastener 125 is released from the material. This also applies when adjusting the product.

[0266] The same applies to Figure 8 , Figure 8a and Figure 8b .exist Figure 8a 2 shows that the length W212 of the attachment area 212 is longer in the transverse direction than the length W203 of the fastening area 203, which is limited by three fastening material areas 203a, 203b, 203c. Figure 8b ), since it is desirable to avoid having adhesive on the outside of the fastener, the attachment area 112 overlaps the entire fastening area except for a small area along the third and fourth outer edges 206, 207. Thus, the area of ​​the attachment area is greater than the area of ​​the fastening area.

[0267] Figure 9a Shows Fig. 9 The cross section AA in Figure 7a are the same and therefore will not be described again. Figure 9b A cross section in the longitudinal direction is shown, wherein the attachment area 212 also extends into a third area 210 and a fourth area 211 of the sheet-formed base 200 which are free of fastening elements, but inside the respective third and fourth outer edges 206 and 207 of the sheet-formed base 200 .

[0268] about Figure 7 , 7a , 7b, 8, 8a, 8b, 9, 9a and 9b, the respective distances D2, D3 and D4 from the fastening area 203 to one of the second, third and fourth outer edges 205, 206, 207 of the base formed by the sheet (i.e. when there is a fastening material-free area on the base formed by the sheet) can be between 3 and 10 mm, for example between 3 and 6 mm, and specifically between 3 and 4 mm. For example, each of the respective distances D2, D3 and D4 can be less than the first distance D1 from the fastening area 203 to the first outer edge 204. For example, each of the respective distances D2, D3 and D4 can be at least 1 mm smaller than the first distance D1, such as at least 2 mm or at least 3 mm.

[0269] Figure 7-9b The fastening area 203 described in the figure comprises a plurality of discrete fastening elements (not shown) comprising rods protruding from the upper surface of the base formed of a sheet material. These rods are hooks that form a hook-and-loop connection with the hooks provided on the first belt portion 123 and the loop-forming material of the second belt portion 124. When the fastener 125 is used in a belt-type product in the front end portion 114 on the top sheet 111, i.e. connected to the two front corners of the top sheet, the outer layers of the two attached belt portions act as loop elements for fixing the second end portion (i.e. the front end portion 114 of the base) to the belt portion, so that the product presents a trouser-like shape, wherein the belt portion forms part of the waist of the trousers.

[0270] when Figure 7-9b When the fastener 125 described in the foregoing is used in an open diaper, Figure 7-9b The fastener 125 described in Figure 1-3 The fastener 25 in the embodiment of the present invention. The fastener 25, namely Figure 7-9b The fasteners 25 described in the foregoing are arranged on the back side panels 23, 24, which are attached to the chassis 10 at the longitudinal side edges near their rear ends. The fasteners 25 are intended to be fastened to the garment-facing surfaces of the respective front side panels 21, 22 (which will act as loop elements), or to the garment-facing surfaces of the chassis 10 (which will act as loop elements), so as to fit the disposable absorbent sanitary product around the waist of the wearer.

[0271] Fig.10 and 10a A fourth embodiment of a fastener 125' is shown, which is designed similar to Figure 7 , 7a , 7b described in the fastener 125 is almost similar. It can also have about Figure 8 , 8a and 8b or 9, 9a and 9b. Only the fourth embodiment will be described with Figure 7 , Figure 7a , Figure 7b The difference between.

[0272] like Fig.10 and Fig.10a As illustrated in the variation of , the base 200 formed of the sheet material can protrude beyond the outer edge 126 of the strap 123. Therefore, the fastening material-free area 208 can at least partially protrude beyond the outer edge 126 of the side strap 123. In this way, the tactile and visual identification of the fastener 125 can be further promoted.

[0273] In some variations, such as Figure 10-10a As shown, the fastening material free area 208 may be located partially on the portion of the sheet-formed base 200 that protrudes beyond the outer edge 126 of the strap 123 and partially on the portion of the sheet-formed base 200 that overlaps the strap 123 .

[0274] In some variations, the fastening material-free area 208 may substantially correspond to the portion of the sheet-formed base 200 that protrudes beyond the outer edge 126 of the belt 123. In other words, the fastening material-free area 208 may extend over 100% of the area of ​​the sheet-formed base 200 that protrudes beyond the outer edge 126 of the belt 123.

[0275] Fig.11 Shows Fig.10 and 10a An alternative fastener 125' is provided in which both the base 200 formed by the sheet and the fastening region 203 protrude beyond said outer edge 126 of the belt portion 123, but still leaves an area 208 free of fastening elements.

[0276] In some variations, such as Fig.11 As shown, the fastening material-free area 208 is completely located on the portion of the base 200 formed from the sheet that protrudes beyond the outer edge 126 of the belt 123, and the fastening area 203 is partially located on the portion of the base 200 formed from the sheet that protrudes beyond the outer edge 126 of the belt 123. For example, the fastening material-free area 208 can extend over at least 30% of the area of ​​the base 200 formed from the sheet that protrudes beyond the outer edge 126 of the belt 123, such as at least 50% or at least 70%.

[0277] For example, and as in Figure 10-10 and / or Fig.11 As exemplified in the variation of , the base 200 formed of the sheet material may protrude a distance F1 of at least 3 mm, such as at least 5 mm, beyond the outer edge 126 of the strap 123. For example, the distance F1 may be between 5 mm and 15 mm.

[0278] Thus, when unfolding or adjusting the product, the wearer or caregiver may optionally grasp the fastening material-free area directly, rather than grasping the side portions and / or the second end portion of the disposable absorbent hygiene product together.

[0279] The area without fastening material may have a color, shape or texture that is completely or partially different from the side and / or the second end portion of the disposable absorbent sanitary product. For example, when at least a portion of the area without fastening material protrudes beyond the outer edge of the side and / or the second end portion, the protruding portion may have a color, shape or texture that is completely or partially different from the rest of the fastener. Having a color, shape or texture that is different from the color, shape or texture of the side and / or the second end portion of the disposable absorbent sanitary product makes it easy for the wearer or caregiver to see the fastener, and this will trigger the wearer or caregiver to grasp the area without fastening material instead of the side and / or the second end portion.

[0280] The fastener 125' includes a protrusion 226 which is a portion of the first fastening material free area 208 on the sheet-formed base 200. The sheet-formed base 200 protrudes beyond the outer edge 126 of the first belt portion 123 in the belt-type product to form the protrusion 226.

[0281] If the fastener 125' is arranged on the second end portion 114 of a belt-type diaper, the base 200 formed by the sheet protrudes beyond the outer edge of the second end portion (i.e., the front end portion 114) (also referred to as the front portion) in the transverse direction to form a protrusion (not shown). If the fastener is arranged on the side panels 23, 24 in an open diaper, the base 200 formed by the sheet protrudes beyond the outer edge of the side panels to form a protrusion (not shown). The attachment area 212' is similar to Figure 7 , 7a and attachment area 212 in 7b. Attachment area 212' does not protrude beyond outer edge 126, as it is not desirable to have adhesive on the exterior of the product.

[0282] The protruding portion can help the caregiver to find the opening of the absorbent product before use, i.e. to identify the end of the drawstring, or to easily find the fastener during use. The protruding portion allows the wearer to grasp the area of ​​the protruding portion without fastening material with his / her fingers. This can reduce the risk of the fastener tearing from the drawstring or the side panel or the second end portion, because when unfolding the product or adjusting the product, the wearer can grasp the fastener directly rather than via the material to which the fastener is attached. Therefore, the attachment strength between the fastener and the part to which it is attached can be reduced.

[0283] The protruding portion, the area without fastening material, or the entire fastener can be provided in a color different from the color of the strap, side panel and / or base so that the wearer can easily see the finger lifting portion. When the finger lifting portion is formed, the base 200 formed by the sheet material can protrude beyond the outer edge 126 by at least about 5 mm, for example, between about 5 mm and about 15 mm.

[0284] Fig.11 Shows Fig.10 and 10a 125 ', wherein both the base 200 and the fastening area 203 formed by the sheet material protrude beyond the outer edge 126 of the belt portion 123, but still leave a fastening element-free area 208. Therefore, when the fastener is attached to the underlying material, the fastening element-free area 208 will be free for grasping to remove the fastener from the fastened position. The attachment area 212 'can have the same Fig.10 and Fig.10a The same dimensions as described and shown in FIG. 2 , except that the attachment area 212 ′ is arranged inside the fastening area 203 on the side where the finger lift 226 is located.

[0285] Fig.12 and Fig.13 Shows Fig.10 and 10a The fastener 125' in Figure 4 The fasteners 125', 148 are arranged on the top sheet 111 in the second end portion 114 of the belt-type product 100. The top sheet 111 and the bottom sheet 112 are attached together by the bonding area 127. The bonding area 127 is connected to the bonding area 127. Fig.10 and 10a The attachment areas 212' are depicted as overlapping, and the bonding area 127 extends beyond the attachment areas 212' in at least one direction.

[0286] Fig.13 Shows Fig.12 The cross section AA in FIG. 1 shows that the bonding area 127 overlaps the entire attachment area 212' and extends beyond the attachment area 212' in both transverse directions T. The same applies to the longitudinal direction L, which can be Fig.12 Thus, the bonding area 127 extends outside the attachment area 212' in all directions. This reduces the risk of the fastener being torn off the top sheet when the product is unfolded or adjusted, as a strong laminate is provided.

[0287] In the longitudinal direction L, the base 200 formed by the sheet and the attachment area 212' may have the same Figure 7bOr the same dimensions as described in 9b. The top sheet 111 and the back sheet 112 are attached to each other in the bonding area by, for example, gluing, heat fusion, ultrasonic welding, etc.

[0288] like Fig.12 As shown, the fastening area 203 can be arranged in a position aligned with the leg elastic member 117 in the longitudinal direction to ensure a good fit and seal with the body to avoid leakage. This also applies to Figure 7 , 7a , 7b, 8, 8a and 8b or any of the fasteners shown in 9, 9a and 9b if they are arranged on the top sheet 111 in the second end portion 114 of the belt-type product 100.

[0289] Bending stiffness measurement method

[0290] The sheets used for evaluation should be conditioned for at least 24 hours in a laboratory environment set at 23°C + / - 1°C and 50% + / - 5% relative humidity. All measurements are performed in the same environment.

[0291] The stiffness (bending resistance) is determined using a Gurley-type tester according to the principles described in the standards ASTM D6125-97 or TAPPI T 543-05. The force required to bend the sample under controlled conditions is determined. The instrument allows a wide variation in the applied force and the length and width of the sample. In the context of the present disclosure, the sample should be 25.4 mm (1 inch) long × 12.7 mm (0.5 inch) wide. The length direction of the sample should coincide with the longitudinal axis of the sanitary product. Samples from the relevant area are cut from the sanitary product. However, if the specified sample size cannot be obtained from the area 208 without fastening material, these samples can be taken instead from pre-treated material sheets (i.e., as received from the material supplier).

[0292] The sample must be uniform, cleanly cut, free of distortions and irregularities. When testing relatively soft materials such as nonwovens, care should be taken not to clamp the sample too tightly into the upper clamp, as the tendency to bend will increase along the attachment line.

[0293] Test results are reported in milligram-force (mgf), where one milligram-force equals one Gurley Unit.

[0294] For each relevant material, a series of 10 individual samples shall be tested and the arithmetic mean calculated therefrom.

[0295] The present disclosure also covers all conceivable combinations of the described aspects, variations, alternatives, and exemplary embodiments of the present disclosure.

[0296] It has been disclosed that open diapers and belt diapers may include a Figure 7-11 It should be understood that in a diaper, different fasteners can be used in the different positions described. Optionally, the same type of fastener can be used in all positions.

[0297] It has been disclosed that open diapers and belt diapers may include Figure 7-11 However, a pant diaper that can be opened and reclosed by a refastening device may also have Figure 7-11 Fasteners shown.

[0298] Furthermore, the present disclosure is not limited to the aforementioned aspects or examples, but naturally applies to other aspects and exemplary embodiments within the scope of the appended claims.

[0299] Reference signs mentioned in the claims should not be considered as limiting the scope of the matter protected by the claims, and their sole function is to make the claims easier to understand.
