Description

Technical Field

[0001] This utility model relates to the field of personal hygiene care products, specifically to a disposable wearable absorbent product. Background Technology

[0002] In existing technology, tapered diapers and pull-up diapers have become standard products for infant care. One of the core functions of these products is their ability to securely fit the wearer's body to prevent leaks and ensure comfort. A key component for achieving this is a mechanical fastener, commonly referred to as a "hook." Currently, this hook is widely used in diaper fastening systems. Specifically, in tapered diapers, the hook is attached to what are called "ear tabs" (also known as "back ear tabs," "elastic ear tabs," or "side waist tabs"). Its main function is to engage with the non-woven fabric side (i.e., the "loop") of the diaper's front waistband, mechanically securing the diaper around the baby's waist for an adjustable fit and secure hold—the core mechanism for leak prevention. In some pull-up diaper designs, the hook is also used to adjust the waistband or reinforce side support.

[0003] In existing manufacturing processes, a specific cutting method is typically used to simultaneously produce the ear flaps (left and right ear flaps) that connect to the left and right sides of the absorbent panel of the diaper. Specifically, this involves combining... Figure 1 As shown, a roughly rectangular raw material with hook components is divided using an S-shaped curve. This S-shaped cutting process efficiently divides a single raw material into two symmetrical parts, directly producing the left and right waistbands for attaching to the absorbent panels of the diaper. This design not only improves material utilization and production efficiency, but the resulting S-shaped contour also mimics a "handle" shape, aiming to provide caregivers with an easy-to-grip and manipulate part, enhancing ease of use.

[0004] However, existing technologies still have room for improvement in terms of material savings and cutting methods. Providing consumers with more useful information is also an area that FMCG manufacturers hope to enhance. Therefore, there is an urgent need for a novel wearable absorbent product that can further optimize production costs while ensuring ease of use. Utility Model Content

[0005] Therefore, the purpose of this invention is to provide a disposable wearable absorbent article that can solve at least one of the above-mentioned deficiencies in the prior art.

[0006] This utility model provides a disposable wearable absorbent article having mutually perpendicular longitudinal and transverse directions, and a thickness direction perpendicular to the longitudinal and transverse directions. The absorbent article is divided along the longitudinal direction into a front waist area, a back waist area, and a crotch area connecting the front waist area and the back waist area. It includes: an absorbent panel having a top layer facing the body, a bottom layer opposite to the top layer and facing the clothing, and an absorbent core located between the top layer and the bottom layer; and a fastening system including a front waistband located in the front waist area and a crotch area located in the crotch area. The rear waist area has a pair of side waist stickers, each side waist sticker having an outer contour. At least one continuously extending dividing line is formed inside each side waist sticker. The line connecting the two endpoints of the dividing line or the perpendicular line between the endpoints of the dividing line and the outer contour forms an outer edge straight line. This outer edge straight line extends generally along the longitudinal direction. The dividing line and the outer edge straight line enclose a foldable adhesive portion. The portion of the side waist sticker, excluding the adhesive portion, includes a fixing portion. This foldable adhesive portion can be folded relative to the fixing portion of the side waist sticker with the outer edge straight line as the fold line and used to adhere to the front waist sticker.

[0013] Preferably, the dividing line intersects with the outer contour of the side waist patch.

[0014] Preferably, the dividing line includes a first dividing line extending laterally and a second dividing line extending longitudinally and intersecting the first dividing line at a first endpoint. The perpendicular line between the second endpoint of the first dividing line away from the second dividing line and the outer contour is the outer edge straight line. The second dividing line intersects the outer contour at a third endpoint. The first dividing line, the second dividing line, the outer edge straight line, and a portion of the outer contour enclose and form the adhesive portion.

[0015] Preferably, the outer contour of the side waist patch includes a first outer contour line and a second outer contour line that are spaced apart from each other and extend along the longitudinal direction. The dividing line includes a first dividing line and a second dividing line that extend along the transverse direction and are spaced apart. The first endpoint and the second endpoint of the first dividing line are respectively located on the first outer contour line and inside the side waist patch. The third endpoint and the fourth endpoint of the second dividing line are respectively located on the second outer contour line and inside the side waist patch. The first endpoint divides the first outer contour line into a first segment and a second segment arranged vertically along the longitudinal direction. The third endpoint divides the second outer contour line into a third segment and a fourth segment arranged vertically along the longitudinal direction. The outer contour also includes a third outer contour line and a fourth outer contour line that are spaced apart vertically along the longitudinal direction and respectively connected between the first outer contour line and the second outer contour line. The perpendicular line between the fourth endpoint and the first dividing line is a first outer edge straight line. The perpendicular line between the two endpoints and the third outer contour line is the second outer edge line. The first outer edge line divides the first dividing line into the fifth and sixth segments. The second outer edge line divides the third outer contour line into the seventh and eighth segments. The second segment, the fourth outer contour line, the second dividing line, the first outer edge line, and the fifth segment enclose and form a fixed part. The third segment, the second dividing line, the first outer edge line, the sixth segment, the second outer edge, and the eighth segment enclose and form a transition part. The second outer edge line, the first dividing line, the first segment, and the seventh segment enclose and form an adhesive part. The transition part and the adhesive part can be folded relative to the fixed part with the first outer edge line as the fold line. The adhesive part can be folded relative to the transition part with the second outer edge line as the fold line and adhered to the front waist sticker.

[0043] Disposable wearable absorbent products

[0044] Figure 1The diagram illustrates a cutting method for a side waist patch 9 in the prior art. The roughly rectangular side waist patch raw material has a hook component in its longitudinal central region. An S-shaped dividing line 94, extending substantially continuously longitudinally, is formed in this central region. At the point closest to the transverse side edges of the S-shaped dividing line 94, multiple longitudinally spaced, transversely extending first horizontal dividing lines 95 and second horizontal dividing lines 96 are provided. The S-shaped dividing line 94, first horizontal dividing lines 95, and second horizontal dividing lines 96 divide the raw material of the side waist patch into multiple symmetrical side waist patches with ergonomic handles. Each side waist patch has a base material portion 92 and an adhesive portion 20 and a fixing portion 30 located on the base material portion 92. The adhesive portion 20 is adhered to the front waist patch of the absorbent product, causing the absorbent product to close. The fixing portion 30 is adhered to the bottom sheet of the absorbent product. This cutting process can simultaneously divide the raw material into two symmetrical parts, thereby directly obtaining left and right waist patches for connection to the left and right sides of the diaper absorbent sheet, respectively. However, the existing front waist patch 9 still has room for improvement in terms of cutting method and saving raw materials.

[0045] Figure 2 , Figure 5 , Figure 8 as well as Figure 11 This invention illustrates a disposable wearable absorbent article having mutually perpendicular longitudinal and transverse directions, and a thickness direction perpendicular to the longitudinal and transverse directions. Along the longitudinal direction, it is divided into a front waist area 1, a back waist area 2, and a crotch area 3 connecting the front waist area 1 and the back waist area 2. It includes an absorbent panel and a fastening system located on the absorbent panel. The absorbent panel has a top layer 4 facing the body, a bottom layer 6 opposite to the top layer 4 and facing the clothing, and an absorbent core 5 located between the top layer 4 and the bottom layer 6. The fastening system includes a front waist patch 7 located in the front waist area 1 and a pair of side waist patches 8 located in the back waist area 2. The side waist patches 8 have dividing lines, such that they are at least divided into a foldable adhesive portion 20 and a fixing portion 30 other than the adhesive portion 20. The adhesive portion 20 can be folded relative to the fixing portion 30 and used to fix it to the front waist patch 7. Through the above methods, the side waist patch 8 of this utility model effectively reduces unnecessary raw material consumption compared with the prior art. While ensuring the convenience of wearing the absorbent product, it also reduces production costs and conforms to the green and environmentally friendly product design concept.

[0046] The side waist patch 8 of this utility model will be described in detail below.

[0047] Example 1

[0048] Combination Figures 2 to 4In one embodiment of this utility model, a non-closed, continuously extending dividing line 100 is formed inside the side waist patch 8. The line connecting the two endpoints of the dividing line 100 is an outer edge straight line 101, which extends generally longitudinally. The dividing line 100 and the outer edge straight line 101 enclose an adhesive portion 20. The part of the side waist patch 8 other than the adhesive portion 20 is a fixing portion 30. The adhesive portion 20 can be folded relative to the fixing portion 30 with the outer edge straight line 101 as the fold line and then adhered to the front waist patch 7. The dividing line 100 is a continuously extending and smoothly transitioning arc. Specifically, the outer edge straight line 101... Figure 3 The image is indicated by a double-dotted line. It can be understood that the side waist patch 8 is typically adhered symmetrically to the left and right sides of the back waist area 2 of the base layer 6, with the longitudinal center of the absorbent material as the axis. Figure 3 It shows Figure 2 The side waist patch 8 on the upper right side covers the front waist patch 7. Figure 4 It shows Figure 3 The middle adhesive part 20 is folded over and bonded to the front waist patch 7.

[0049] Furthermore, preferably, the outer contour of the side waist patch 8 has a straight edge 102 extending longitudinally, and the adhesive portion 20 covers at least a portion of the straight edge 102 after being folded over, wherein preferably the longitudinal extension length of the outer edge straight line 101 itself is not less than the vertical distance between the outer edge straight line 101 and the straight edge 102.

[0050] Furthermore, the front waist patch 7 can display information on multiple different dimensions of the same body dimension, and the side waist patch 8 has a notch area 40 formed in response to the folding of the adhesive portion 20. After the adhesive portion 20 is adhered to the front waist patch 7, the size information of the front waist patch 7 corresponding to the wearer's body dimension is displayed through the notch area 40. (See reference) Figure 4 The body dimension can be the waist circumference, and the size information is symmetrical about the longitudinal centerline of the absorbent product. In one embodiment, the size information on the front waist patch 7 can be the numbers 1, 2, 3, and 4 arranged sequentially, and the numbers gradually increase from the longitudinal center of the absorbent product outwards.

[0051] In this system, 1 represents the smallest size of the absorbent product, 2 represents the small size, 3 represents the medium size, and 4 represents the large size. Assuming a consumer purchases a small-sized absorbent product, the correct size should, after wearing, show the number "2" on the front waist patch 7 through the notch area 40. If the area between the numbers "2" and "3" on the front waist patch 7, or an area further outward from the number "2," is visible through the notch area 40, it indicates that the absorbent product is not suitable for the wearer. The wearer's caregiver, i.e., the consumer, needs to purchase a larger size absorbent product. This implementation method visually demonstrates the fit between the absorbent product size and the wearer, allowing consumers to better understand changes in their body dimensions and thus easily select a suitable absorbent product.

[0052] Furthermore, the adhesive portion 20 may include an operating area 220 for finger gripping and a bonding area 210 for bonding to the front waist patch 7. The operating area 220 comprises a nonwoven fabric, and the bonding area 210 comprises a substrate 22 and hook material 23 located on the substrate 22. Preferably, the basis weight of the nonwoven fabric is not less than 20 gsm, and the basis weight of the bonding area 210 is preferably not less than 50 gsm. (Refer to...) Figure 15 The substrate 22 has an overall planar shape, and the hook material 23 may have a plurality of bidirectional micro-sized hooks. The micro-sized hooks may be distributed across the engagement area 210 in various patterns and hook densities. For example, the hooks may be arranged in rows and / or columns, or any other arrangement of hooks known in the art. In various embodiments, the engagement area 210 may have 10-1,000 hooks / cm², or any integer number of hooks between 10 and 1,000, or a hook density within any range formed by any of these values. Examples suitable for the engagement area 210 are as follows. The engagement area 210 may include hooks of any shape, such as a "J" shape, a "T" shape, or a mushroom shape, or any other shape known in the art.

[0053] When a hook is used on a side waist patch 8 of a fastening system having an engagement area 210, and the fastening system uses a fibrous material as the material for the front waist patch 7, the overall hook height can be determined based on the overall thickness of the fibrous material, such as the overall thickness of the material of the front waist patch 7. The overall hook height can be 33-200% of the overall thickness of the fibrous material, or any integer percentage between 33% and 200% of the overall thickness of the fibrous material, or any range formed by any of these values. For example, the overall hook height can be 33%, 50%, 100%, 150%, or 200% of the overall thickness of the fibrous material, or any range formed by any of these values. Unbound by this theory, it is believed that selecting the overall hook height based on the overall thickness of the fibrous material as described above allows the hook to penetrate the fibrous material to a significant depth, which increases the likelihood that the hook may encounter fibers to be captured by the hook.

[0054] The side waist patch 8 can be made from a wide variety of moldable and / or formable materials, including any natural or synthetic materials mentioned herein and / or any other suitable materials known in the art in any feasible combination thereof, together with any additives or processing aids known in the art. As a specific example, the side waist patch 8 can be made from a variety of renewable materials, including protoplasts derived from renewable biomass sources such as sugars, starches, cellulose, biopolymers, etc. In various alternative embodiments, the hooks and the substrate can be formed independently or made from different materials. Exemplary side waist patch 8 materials are available under trade names 960, 957, and 942 from Aplix, Inc. (Charlotte, NC, USA). Other side waist patch 8 materials are available under trade names CS200, CS300, MC5, and MC6 from 3M Company (St. Paul, Minnesota, USA).

[0055] Example 2

[0056] Combination Figures 5 to 7 In one embodiment of this utility model, the dividing line 100 includes two first dividing lines 200 extending laterally and spaced apart longitudinally, and a second dividing line 300 connecting the endpoints of the two first dividing lines 200. The second dividing line 300 extends longitudinally. The line connecting the two endpoints of the two first dividing lines 200 away from the second dividing line 300 is an outer edge straight line 101. The two first dividing lines 200, the second dividing line 300, and the outer edge straight line 101 enclose and form an adhesive portion 20. The portion of the side waist patch 8 outside the adhesive portion 20 is a fixing portion 30. The adhesive portion 20 can be folded relative to the fixing portion 30 and adhered to the front waist patch 7 using the outer edge straight line 101 as a folding line. The adhesive portion 20 is rectangular, and the outer edge straight line 101... Figure 6The image is indicated by a double-dotted line. It can be understood that the side waist patch 8 is typically adhered symmetrically to the left and right sides of the back waist area 2 of the base layer 6, with the longitudinal center of the absorbent material as the axis. Figure 6 It shows Figure 5 Fold the upper right side waist sticker 8 and attach it to the front waist sticker 7. Figure 7 It shows Figure 6 The middle adhesive part 20 is folded over and bonded to the front waist patch 7.

[0057] Furthermore, the outer contour of the side waist sticker 8 has a straight edge 102 extending longitudinally, and the adhesive portion 20 covers at least a portion of the straight edge 102 after being folded over. The longitudinal extension length of the outer edge straight line 101 itself is not less than the vertical distance between the outer edge straight line 101 and the straight edge 102.

[0058] Furthermore, the front waist patch 7 can display information on multiple different dimensions of the same body dimension, and the side waist patch 8 has a notch area 40 formed in response to the folding of the adhesive portion 20. After the adhesive portion 20 is adhered to the front waist patch 7, the size information of the front waist patch 7 corresponding to the wearer's body dimension is displayed through the notch area 40. (See reference) Figure 6 The body dimension can be waist circumference, and the size information is symmetrically arranged with the longitudinal center line of the absorbent product as the axis. In one embodiment, the size information on the front waist patch 7 can be the numbers 1, 2, 3, and 4 arranged sequentially, and these numbers gradually increase outward from the longitudinal center of the absorbent product. Here, 1 can represent the smallest size of the absorbent product, 2 can represent the small size, 3 can represent the medium size, and 4 can represent the large size. Assuming the consumer purchases a small-sized absorbent product, the appropriate absorbent product, after being worn, should display the number "2" on the front waist patch 7 through the notch area 40. If the area between the numbers "2" and "3" on the front waist patch 7, or an area further outward from the number "2," is displayed through the notch area 40, it indicates that the absorbent product size is not suitable for the wearer, and the wearer's caregiver, i.e., the consumer, needs to purchase a larger size absorbent product. Through the above implementation, the fit between the absorbent product size and the wearer is intuitively demonstrated, allowing consumers to more clearly understand changes in the wearer's body dimensions, thus facilitating the selection of absorbent products that fit the wearer's size.

[0059] Furthermore, the adhesive portion 20 may include an operating area 220 for finger gripping and a bonding area 210 for bonding to the front waist patch 7. The bonding area 210 includes a substrate 22 and hook material 23 located on the substrate 22. The portion of the adhesive portion 20 other than the bonding area 210 comprises nonwoven fabric, preferably with a basis weight of not less than 20 gsm, and the basis weight of the bonding area 210 is preferably not less than 50 gsm. (Refer to...) Figure 15The substrate 22 has an overall planar shape, and the hook material 23 may have a plurality of bidirectional micro-sized hooks. The micro-sized hooks may be distributed across the engagement area 210 in various patterns and hook densities. For example, the hooks may be arranged in rows and / or columns, or any other arrangement of hooks known in the art. In various embodiments, the engagement area 210 may have 10-1,000 hooks / cm², or any integer number of hooks between 10 and 1,000, or a hook density within any range formed by any of these values. Examples suitable for the engagement area 210 are as follows. The engagement area 210 may include hooks of any shape, such as a "J" shape, a "T" shape, or a mushroom shape, or any other shape known in the art.

[0060] When a hook is used on a side waist patch 8 of a fastening system having an engagement area 210, and the fastening system uses a fibrous material as the material for the front waist patch 7, the overall hook height can be determined based on the overall thickness of the fibrous material, such as the overall thickness of the material of the front waist patch 7. The overall hook height can be 33-200% of the overall thickness of the fibrous material, or any integer percentage between 33% and 200% of the overall thickness of the fibrous material, or any range formed by any of these values. For example, the overall hook height can be 33%, 50%, 100%, 150%, or 200% of the overall thickness of the fibrous material, or any range formed by any of these values. Unbound by this theory, it is believed that selecting the overall hook height based on the overall thickness of the fibrous material as described above allows the hook to penetrate the fibrous material to a significant depth, which increases the likelihood that the hook may encounter fibers to be captured by the hook.

[0061] The side waist patch 8 can be made from a wide variety of moldable and / or formable materials, including any natural or synthetic materials mentioned herein and / or any other suitable materials known in the art in any feasible combination thereof, together with any additives or processing aids known in the art. As a specific example, the side waist patch 8 can be made from a variety of renewable materials, including protoplasts derived from renewable biomass sources such as sugars, starches, cellulose, biopolymers, etc. In various alternative embodiments, the hooks and the substrate can be formed independently or made from different materials. Exemplary side waist patch 8 materials are available under trade names 960, 957, and 942 from Aplix, Inc. (Charlotte, NC, USA). Other side waist patch 8 materials are available under trade names CS200, CS300, MC5, and MC6 from 3M Company (St. Paul, Minnesota, USA).

[0062] Example 3

[0063] Reference Figures 8 to 10In one embodiment of this utility model, the dividing line 100 intersects with the outer contour of the side waist patch 8, and the dividing line 100 includes a first dividing line 200 extending laterally and a second dividing line 300 extending longitudinally and intersecting the first dividing line 200 at a first endpoint 201. The second endpoint 202 of the first dividing line 200 away from the second dividing line 300 and the perpendicular line to the outer contour line extending laterally form an outer edge straight line 101. The second dividing line 300 intersects the outer contour line at a third endpoint 301. The first dividing line 200, the second dividing line 300, the outer edge straight line 101 and part of the outer contour line surround and form an adhesive portion 20.

[0064] The portion of the side waist sticker 8 outside the adhesive portion 20 is the fixing portion 30. The adhesive portion 20 can be folded relative to the fixing portion 30 and adhered to the front waist sticker 7, with the outer edge straight line 101 as the fold line. The adhesive portion 20 is rectangular, and the outer edge straight line 101... Figure 9 The image is indicated by a double-dotted line. It can be understood that the side waist patch 8 is typically adhered symmetrically to the left and right sides of the back waist area 2 of the base layer 6, with the longitudinal center of the absorbent material as the axis. Figure 9 It shows Figure 8 The side waist patch 8 on the upper right side covers the front waist patch 7. Figure 10 It shows Figure 9 The middle adhesive part 20 is folded over and bonded to the front waist patch 7.

[0065] Furthermore, the outer contour of the side waist sticker 8 has a straight edge 102 extending longitudinally, and the adhesive portion 20 covers at least a portion of the straight edge 102 after being folded over. The longitudinal extension length of the outer edge straight line 101 itself is not less than the vertical distance between the outer edge straight line 101 and the straight edge 102.

[0066] Furthermore, the front waist patch 7 can display information on multiple different dimensions of the same body dimension, and the side waist patch 8 has a notch area 40 formed in response to the folding of the adhesive portion 20. After the adhesive portion 20 is adhered to the front waist patch 7, the size information of the front waist patch 7 corresponding to the wearer's body dimension is displayed through the notch area 40. (See reference) Figure 8The body dimension can be waist circumference, and the size information is symmetrically arranged with the longitudinal center line of the absorbent product as the axis. In one embodiment, the size information on the front waist patch 7 can be the numbers 1, 2, 3, and 4 arranged sequentially, and these numbers gradually increase outward from the longitudinal center of the absorbent product. Here, 1 can represent the smallest size of the absorbent product, 2 can represent the small size, 3 can represent the medium size, and 4 can represent the large size. Assuming the consumer purchases a small-sized absorbent product, the appropriate absorbent product, after being worn, should display the number "2" on the front waist patch 7 through the notch area 40. If the area between the numbers "2" and "3" on the front waist patch 7, or an area further outward from the number "2," is displayed through the notch area 40, it indicates that the absorbent product size is not suitable for the wearer, and the wearer's caregiver, i.e., the consumer, needs to purchase a larger size absorbent product. Through the above implementation, the fit between the absorbent product size and the wearer is intuitively demonstrated, allowing consumers to more clearly understand changes in the wearer's body dimensions, thus facilitating the selection of absorbent products that fit the wearer's size.

[0067] Furthermore, the adhesive portion 20 can be used for the finger-pinching operating area 220 and for bonding to the front waist patch 7, the bonding area 210 including a substrate 22 and hook material 23 located on the substrate 22, wherein the portion of the adhesive portion 20 other than the bonding area 210 includes non-woven fabric, the basis weight of which is preferably not less than 20 gsm, and the basis weight of the bonding area 210 is preferably not less than 50 gsm. (Refer to...) Figure 15 The substrate 22 has an overall planar shape, and the hook material 23 may have a plurality of bidirectional micro-sized hooks. The micro-sized hooks may be distributed across the engagement area 210 in various patterns and hook densities. For example, the hooks may be arranged in rows and / or columns, or any other arrangement of hooks known in the art. In various embodiments, the engagement area 210 may have 10-1,000 hooks / cm², or any integer number of hooks between 10 and 1,000, or a hook density within any range formed by any of these values. Examples suitable for the engagement area 210 are as follows. The engagement area 210 may include hooks of any shape, such as a "J" shape, a "T" shape, or a mushroom shape, or any other shape known in the art.

[0068] When a hook is used on a side waist patch 8 of a fastening system having an engagement area 210, and the fastening system uses a fibrous material as the material for the front waist patch 7, the overall hook height can be determined based on the overall thickness of the fibrous material, such as the overall thickness of the material of the front waist patch 7. The overall hook height can be 33-200% of the overall thickness of the fibrous material, or any integer percentage between 33% and 200% of the overall thickness of the fibrous material, or any range formed by any of these values. For example, the overall hook height can be 33%, 50%, 100%, 150%, or 200% of the overall thickness of the fibrous material, or any range formed by any of these values. Unbound by this theory, it is believed that selecting the overall hook height based on the overall thickness of the fibrous material as described above allows the hook to penetrate the fibrous material to a significant depth, which increases the likelihood that the hook may encounter fibers to be captured by the hook.

[0069] The side waist patch 8 can be made from a wide variety of moldable and / or formable materials, including any natural or synthetic materials mentioned herein and / or any other suitable materials known in the art in any feasible combination thereof, together with any additives or processing aids known in the art. As a specific example, the side waist patch 8 can be made from a variety of renewable materials, including protoplasts derived from renewable biomass sources such as sugars, starches, cellulose, biopolymers, etc. In various alternative embodiments, the hooks and the substrate can be formed independently or made from different materials. Exemplary side waist patch 8 materials are available under trade names 960, 957, and 942 from Aplix, Inc. (Charlotte, NC, USA). Other side waist patch 8 materials are available under trade names CS200, CS300, MC5, and MC6 from 3M Company (St. Paul, Minnesota, USA).

[0070] Example 4

[0071] like Figures 11 to 14As shown, in one embodiment of this utility model, the outer contour of the side waist patch 8 includes a first outer contour line 24 and a second outer contour line 25 that are spaced apart from each other and extend longitudinally. The dividing line 100 includes a first dividing line 200 and a second dividing line 300 that extend laterally and are spaced apart. The first endpoint 201 and the second endpoint 202 of the first dividing line 200 are located on the first outer contour line 24 and inside the side waist patch 8, respectively. The third endpoint 301 and the fourth endpoint 302 of the second dividing line 300 are located on the second outer contour line 25 and inside the side waist patch 8, respectively. The first endpoint 201 divides the first outer contour line 24 into a first segment 241 and a second segment 242 arranged vertically in the longitudinal direction. The third endpoint 203 divides the second outer contour line 25 into a third segment 251 and a fourth segment 252 arranged vertically in the longitudinal direction. The outer contour of the side waist patch 8 also includes a third outer contour line 26 and a fourth outer contour line 27, which are arranged vertically and vertically between the first outer contour line 24 and the second outer contour line 25, respectively. The perpendicular line between the fourth endpoint 302 and the first dividing line 200 is the first outer edge line 112, and the perpendicular line between the second endpoint 202 and the third outer contour line 26 is the second outer edge line 113. The first outer edge line 112 divides the first dividing line 200 into a fifth segment 211 and a sixth segment 212. Two outer edge straight lines 113 divide the third outer contour line 26 into a seventh segment 261 and an eighth segment 262; the second segment 242, the fourth outer contour line 27, the fourth segment 252, the second dividing line 300, the first outer edge straight line 112, and the fifth segment 211 enclose to form a fixing part 30; the third segment 251, the second dividing line 300, the first outer edge straight line 112, the sixth segment 212, the second outer edge straight line 113, and the eighth segment 262 enclose to form a transition part 50. The second outer edge straight line 113, the first dividing line 200, the first segment 241, and the seventh segment 261 enclose to form an adhesive part 20.

[0072] The transition portion 50 and the adhesive portion 20 can be folded relative to the fixing portion 30 along the first outer edge straight line 112, and the adhesive portion 20 can be folded relative to the transition portion 50 along the second outer edge straight line 113 and adhered to the front waist sticker 7. Specifically, the first outer edge straight line 112 and the second outer edge straight line 113 are... Figure 12 and Figure 13 The image is indicated by a double-dotted line. It can be understood that the side waist patch 8 is typically located symmetrically on the left and right sides of the back waist area 2, with the longitudinal center of the absorbent material as the axis. Figure 12 yes Figure 11 The side waist patch 8 on the upper right side covers the front waist patch 7. Figure 13 yes Figure 12 The state of the intermediate transition portion 50 and the adhesive portion 20 after being folded relative to the fixing portion 30. Figure 14 yes Figure 13 The state of the middle adhesive portion 20 after being folded relative to the transition portion 50.

[0073] Furthermore, the front waist patch 7 can display information on multiple different dimensions of the same body dimension, and the side waist patch 8 has a notch area 40 formed in response to the folding of the adhesive portion 20. After the adhesive portion 20 is adhered to the front waist patch 7, the size information of the front waist patch 7 corresponding to the wearer's body dimension is displayed through the notch area 40. (See reference) Figure 13 and Figure 14 The body dimension can be waist circumference, and the size information is symmetrically arranged about the longitudinal centerline of the absorbent product. In one embodiment, the size information on the front waist patch 7 can be the numbers 1, 2, 3, and 4 arranged sequentially, with the numbers gradually increasing outward from the longitudinal center of the absorbent product. Here, 1 can represent the smallest size of the absorbent product, 2 can represent the small size, 3 can represent the medium size, and 4 can represent the large size. Assuming the consumer purchases a small-sized absorbent product, the appropriate absorbent product, after being worn, should display the number "2" on the front waist patch 7 through the notch area 40. If the area between the numbers "2" and "3" on the front waist patch 7, or an area further outward from the number "2," is displayed through the notch area 40, it indicates that the absorbent product size is unsuitable for the wearer, and the wearer's caregiver, i.e., the consumer, needs to purchase a larger size absorbent product. Through the above implementation, the fit between the absorbent product size and the wearer is intuitively demonstrated, allowing consumers to more clearly understand changes in the wearer's body dimensions, thus facilitating the selection of absorbent products that fit the wearer's size.

[0074] Furthermore, the adhesive portion 20 may include an operating area 220 for finger gripping and a bonding area 210 for bonding to the front waist patch 7. The bonding area 210 includes a substrate 22 and hook material 23 located on the substrate 22. The portion of the adhesive portion 20 other than the bonding area 210 comprises nonwoven fabric, preferably with a basis weight of not less than 20 gsm, and the basis weight of the bonding area 210 is preferably not less than 50 gsm. (Refer to...) Figure 15 The substrate 22 has an overall planar shape, and the hook material 23 may have a plurality of bidirectional micro-sized hooks. The micro-sized hooks may be distributed across the engagement area 210 in various patterns and hook densities. For example, the hooks may be arranged in rows and / or columns, or any other arrangement of hooks known in the art. In various embodiments, the engagement area 210 may have 10-1,000 hooks / cm², or any integer number of hooks between 10 and 1,000, or a hook density within any range formed by any of these values. Examples suitable for the engagement area 210 are as follows. The engagement area 210 may include hooks of any shape, such as a "J" shape, a "T" shape, or a mushroom shape, or any other shape known in the art.

[0075] When a hook is used on a side waist patch 8 of a fastening system having an engagement area 210, and the fastening system uses a fibrous material as the material for the front waist patch 7, the overall hook height can be determined based on the overall thickness of the fibrous material, such as the overall thickness of the material of the front waist patch 7. The overall hook height can be 33-200% of the overall thickness of the fibrous material, or any integer percentage between 33% and 200% of the overall thickness of the fibrous material, or any range formed by any of these values. For example, the overall hook height can be 33%, 50%, 100%, 150%, or 200% of the overall thickness of the fibrous material, or any range formed by any of these values. Unbound by this theory, it is believed that selecting the overall hook height based on the overall thickness of the fibrous material as described above allows the hook to penetrate the fibrous material to a significant depth, which increases the likelihood that the hook may encounter fibers to be captured by the hook.

[0076] The side waist patch 8 can be made from a wide variety of moldable and / or formable materials, including any natural or synthetic materials mentioned herein and / or any other suitable materials known in the art in any feasible combination thereof, together with any additives or processing aids known in the art. As a specific example, the side waist patch 8 can be made from a variety of renewable materials, including protoplasts derived from renewable biomass sources such as sugars, starches, cellulose, biopolymers, etc. In various alternative embodiments, the hooks and the substrate can be formed independently or made from different materials.
