[0005] Patent Document 1: Japanese Patent Application Publication No. 2019-136286 Summary of the Invention

[0006] However, even with the same weight, the position of the front and back ends of absorbent materials can sometimes deviate from the ideal position due to differences in each wearer's physique (e.g., body size). This can result in the absorbent material not fitting properly, leading to a poor wearing experience and / or leakage of excrement.

[0007] Furthermore, the wearer's weight can easily vary depending on daily diet, exercise, and the development of any illness. Therefore, if the wearer's hips are positioned according to markings that do not match the actual weight of the wearer, absorbent materials may not fit properly.

[0008] Therefore, the object of the present invention is to provide an absorbent article having a marking portion indicating the placement position of a part of the wearer's body, which allows an installation assistant to properly install the absorbent article onto the wearer.

[0009] One absorbent article comprises: a front-back direction and a width direction orthogonal to the front-back direction; and a marking portion indicating the partial placement of a wearer's body. The marking portion at least partially indicates the placement of the wearer's bones and is positioned outside the central region of the absorbent article in the width direction.

[0018] (1) Overview of the implementation method

[0019] One type of absorbent article is an absorbent article having: a front-back direction and a width direction orthogonal to the front-back direction; and a marking portion indicating the placement of a portion of the wearer's body. The marking portion at least partially indicates the placement of the wearer's bones and is positioned outside the width direction of the central region of the absorbent article.

[0020] Compared to the wearer's hips, the position of the wearer's bones is less affected by changes in the wearer's physique and weight. Therefore, even though each wearer has a different body type, the absorbent material can be properly installed on each wearer by aligning the position of their bones with the markings indicating the placement of their bones. This prevents the front and rear ends of the absorbent material from shifting from their ideal positions, thus suppressing discomfort and / or leakage of excrement. Furthermore, the markings are positioned wider than the central area, making them less likely to be obscured by the wearer's body compared to when they are positioned in the central area. This allows the installer to easily visually identify the markings, facilitating easy installation of the absorbent material using them as a reference.

[0021] In a preferred embodiment, the marking may indicate the placement of the wearer's iliac crest. In cases where multiple installers in hospitals and / or care facilities are installing absorbent articles on wearers (especially the elderly), the identification of the buttocks may differ for each installer. Therefore, even if some installers align the wearer's buttocks with the marking indicating the buttocks' placement, the absorbent article may not be properly installed. Here, the iliac crest is typically located in the protruding part near the wearer's waist; therefore, installers can easily identify the iliac crest's location not only visually but also accurately by touching the wearer's waist. Thus, based on accurate identification of the iliac crest's location, each installer can align the wearer's iliac crest with the marking, enabling proper installation of the absorbent article.

[0022] According to a preferred embodiment, the absorbent article may have: a front waist region, a back waist region, and a crotch region disposed between the front waist region and the back waist region; and a hook-and-loop fastener disposed in the back waist region and secured to the front waist region. The marking portion may be at least partially disposed behind the front edge of the hook-and-loop fastener and forward of the rear edge of the hook-and-loop fastener. Thus, with the wearer's bones aligned with the marking portion, the area between the front and rear edges of the hook-and-loop fastener, secured to the front waist region, closely adheres to the wearer's body, preventing the wearer's bones from easily shifting away from the marking portion. Therefore, the absorbent article can be properly installed, thus continuously suppressing the deterioration of wearing comfort and / or leakage of excrement.

[0023] According to a preferred embodiment, the hook and loop fastener may have: a first engaging portion that engages with the front waist region; and a second engaging portion that engages with the front waist region at a position inside the front-rear direction compared to the first engaging portion. Alternatively, the marking portion may be at least partially positioned forward of the rear end edge of the first engaging portion and rearward of the rear end edge of the second engaging portion. Thus, by engaging the first and second engaging portions in a manner that at least a portion of the marking portion is clamped in the front-rear direction, the wearer's skeletal position is less likely to shift from the marking portion. Therefore, it is possible to maintain the absorbent article in a properly installed state.

[0024] According to a preferred embodiment, the marking portion may consist of a pair of marking portions disposed on both outer sides of the central region in the width direction. The absorbent article may have: a front waist region, a back waist region, and a crotch region disposed between the front waist region and the back waist region; and a pair of leak-proof seams extending in the front-back direction at least in the crotch region, and disposed on both sides across the center of the absorbent article in the width direction, i.e., the width center. The pair of leak-proof seams may have: a raised portion capable of rising towards the skin side by contraction in the front-back direction; and a front-back joining portion located on the outer side of the raised portion in the front-back direction, and joined in a manner that prevents it from rising towards the skin side. Each of the pair of marking portions may be at least partially disposed on the outer side of the front-back joining portion on the width center side in the width direction. With the pair of marking portions, the marking portion can be visually identified from either the left or right side of the wearer's body. Furthermore, the area inside the front and rear joints in the width direction is the area for collecting excrement and is where the wearer's body rests when the absorbent material is installed. Therefore, by positioning the marking portion outside the area where the wearer's body rests (i.e., the area inside the front and rear joints in the width direction), the marking portion is less likely to be obscured by the wearer's body. As a result, the installer can easily visually identify the marking portion, and thus the absorbent material can be easily installed using the marking portion as a reference.

[0025] In a preferred embodiment, each of the pair of marking portions may be positioned at least partially outside the width direction of the raised end edge. Since the raised portion blocks excrement, the area inside the width direction of the raised end edge is an area where the wearer's body is easily supported when installing the absorbent article. Therefore, by positioning the marking portion outside the width direction of the area where the wearer's body is easily supported (i.e., the area inside the width direction of the raised end edge), the marking portion is less likely to be obscured by the wearer's body. This makes it easier for the installation assistant to visually identify the marking portion.

[0026] According to a preferred embodiment, the absorbent article may have one or more sheets disposed at a position closer to the skin side than the marking portion. Thus, the marking portion does not come into direct contact with the wearer's skin, thereby suppressing any effects on the wearer's skin caused by the marking portion (e.g., ink movement towards the skin, or ink damage to the skin, when the marking portion is set using ink-formed characters).

[0027] In a preferred embodiment, the absorbent article may include a shrinkable member. The marking portion may be disposed in a region that does not overlap with the shrinkable member in the thickness direction. Therefore, the area where the marking portion is disposed is less likely to shrink due to the shrinkage of the shrinkable member, thus suppressing a decrease in the visual recognizability of the marking portion.

[0028] In a preferred embodiment, the markings may indicate the range of the wearer's bone placement in the front-back direction. This allows the installer to freely adjust the wearer's bone placement within the range indicated by the markings. This reduces the mental burden on the installer, who must precisely position the wearer's bones for proper installation. Furthermore, compared to precisely positioning the wearer's bones, the time spent adjusting the bone placement is reduced, thus shortening the installation time.

[0029] Furthermore, when multiple installers attach absorbent materials to the wearer, compared to the case where the markings indicate the precise placement of the bones, each installer can more easily position the wearer's bones within the range shown by the markings. Therefore, multiple installers can appropriately attach absorbent materials to each other.

[0030] In a preferred embodiment, the markings may graphically represent the mounting location of the absorbent article and the placement of the wearer's bones. This allows the installer to clearly identify the mounting location and the placement of the wearer's bones using the graphics, making it easy to understand the meaning of the markings and facilitating the installation of the absorbent article using the markings as a reference.

[0031] In a preferred embodiment, the markings may use text to indicate the bone structure of the wearer that should be positioned at the location indicated by the markings. Thus, an installation assistant who has visually recognized the text can use the markings to understand the correct bone structure of the wearer, thereby reducing the likelihood of the installation assistant incorrectly positioning other parts of the wearer's body.

[0032] In a preferred embodiment, the absorbent article may have other markings with a design different from the marked portion. The marked portion may be separate from the other markings in the front-back direction. This makes it easier for the wearer to recognize the difference between the marked portions and the other markings, reducing the likelihood of the wearer's bones misaligning with the other markings.

[0033] In a preferred embodiment, at least a portion of the marking portion overlaps with the other marking portions in the front-back direction. Therefore, when other marking portions are found, the marking portion can be located by moving the line of sight in the front-back direction, making it easy for the installation assistant to spot. Consequently, the installation assistant can easily install the absorbent article using the marking portion as a reference.

[0034] According to a preferred embodiment, the absorbent article may have: a front waist region, a back waist region, and a crotch region disposed between the front waist region and the back waist region; and a hook and loop fastener disposed in the back waist region and secured to the front waist region. The marking portion and other marking portions may be positioned rearward than the front edge of the hook and loop fastener. Therefore, when other marking portions are discovered, the marking portion is also easily visible, making it easy for the installation assistant to locate. Consequently, the installation assistant can easily install the absorbent article using the marking portion as a reference.

[0035] In the following embodiments, the “marking portion” described in the claims corresponds to the body marking portion, and the “other marking portion” described in the claims corresponds to the pad marking portion.

[0036] (2) Overall general structure of absorbent materials

[0037] Hereinafter, the absorbent article according to the embodiments will be described with reference to the accompanying drawings. Furthermore, in the following description of the drawings, the same or similar parts will be labeled with the same or similar reference numerals. However, it should be noted that the drawings are schematic diagrams, and the proportions of each dimension may differ from actual proportions. Therefore, specific dimensions should be determined by referring to the following description. Additionally, the drawings may contain parts with different dimensional relationships or proportions. Furthermore, when comparing the length and positional relationships of the present invention, unless otherwise specifically mentioned, an absorbent article in an elongated state, where the absorbent article is stretched to a state where wrinkles are not formed by the stretchable members, is used. Figure 4 Indicates in Figure 3 The state in which the erected part 61, described later, is erected at line F4-F4.

[0038] The absorbent article in this embodiment is a disposable diaper for adults. The absorbent article is preferably of the type that is installed by an installer, such as a caregiver, onto a wearer (especially the elderly). Additionally, in this embodiment, an absorbent pad 100 can be attached to the absorbent article 10. The absorbent pad 100 is attached to the absorbent article 10 on its skin-side surface.

[0039] The absorbent article 10 has a front-to-back direction L and a width direction W. The front-to-back direction L extends towards the front and back of the wearer's body. The width direction W is orthogonal to the front-to-back direction L. The absorbent article 10 has a thickness direction T that is orthogonal to both the front-to-back direction L and the width direction W. In this specification, "skin side" refers to the side facing the wearer's skin during use. "Non-skin side" refers to the side facing the opposite side of the wearer's skin during use. The thickness direction T extends towards the skin side T1 and the non-skin side T2.

[0040] The absorbent article 10 has a front waist area S1, a back waist area S2, and a crotch area S3. The front waist area S1 faces the front of the wearer's body when in use. The back waist area S2 faces the rear of the wearer's body when in use. The crotch area S3 is located between the front waist area S1 and the back waist area S2. The crotch area S3 is located in the wearer's crotch area when in use. Alternatively, the crotch area S3 may be a region with a leg opening 15, with the front waist area S1 and the crotch area S3 defined by the front edge of the leg opening 15, and the back waist area S2 and the crotch area S3 defined by the rear edge of the leg opening 15.

[0041] The absorbent article 10 may have an absorbent core 50 disposed at least in the crotch region S3. The absorbent core 50 extends from the crotch region S3 to the front waist region S1 and the back waist region S2. The absorbent core 50 may be, for example, a laminate of absorbent material containing pulverized pulp or superabsorbent polymer (SAP) or a mixture thereof. Furthermore, the outer edge 50E of the absorbent core 50 has an innermost outer edge 50IE in the width direction W. The absorbent article 10 may have an absorbent body comprising the absorbent core 50 and a core-covering layer (not shown). The core-covering layer is disposed in a manner that covers the absorbent core 50, and may be, for example, cotton paper or a nonwoven sheet.

[0042] The absorbent article 10 may have a skin sheet 41 located on the skin side T1 of the absorbent core 50 and a non-skin sheet 42 located on the non-skin side T2 of the absorbent core 50. The skin sheet 41 may have a top sheet 41a and side sheets 41b. The top sheet 41a may be liquid-permeable and is arranged to cover at least the center of the absorbent core 50 in the width direction W. The side sheets 41b may be made of a hydrophobic nonwoven fabric and are arranged to cover both sides of the top sheet 41a in the width direction W, at a position outside the center of the absorbent core 50 in the width direction W. The non-skin sheet 42 may be liquid-impermeable and is located on the non-skin side of the absorbent core 50. The non-skin sheet 42 may have a liquid-impermeable backing membrane 42a and a backing nonwoven fabric 42b disposed on the non-skin side of the backing membrane 42a.

[0043] The absorbent article 10 may have a pair of leak-proof seams 60. The pair of leak-proof seams 60 extend in the front-to-back direction L at least in the crotch area S3. The pair of leak-proof seams 60 are disposed on both sides with respect to the center of the width direction W of the absorbent article 10, i.e., the width center WC. The pair of leak-proof seams 60 may have a raised portion 61, a front-to-back joint portion 62, a width joint portion 63, and a leak-proof elastic member 65.

[0044] The raised portion 61 can be raised towards the skin surface T1 by contraction in the front-back direction L. The front-back joint portion 62 is located on the outer side of the raised portion 61 in the front-back direction L, and is joined in such a way that it cannot be raised towards the skin surface T1. The front-back joint portion 62 has an inner edge 62E located on the width center WC side and an inner end edge located on the crotch side (i.e., the front end edge 62F of the front-back joint portion 62 in the back waist area S2). The width joint portion 63 is located on the outer side of the raised portion 61 in the width direction W, and is joined in such a way that it cannot be raised towards the skin surface T1. The leak-proof elastic member 65 is arranged on the side plate 41b in an elongated state in the front-back direction L. The leak-proof elastic member 65 can be clamped and fixed by the side plate 41b. By contraction of the leak-proof elastic member 65, the raised portion 61 can be raised by contraction in the front-back direction L. Figure 4As shown, the erected portion 61 rises from the erected end edge 61WE in the width direction W. The erected end edge 61WE is formed by the inner edge of the width joint portion 63 in the width direction W. Additionally, the erected portion 61 rises from the erected end edge 61LE in the front-rear direction L. The erected end edge 61LE is formed by the inner end edge of the front-rear joint portion 62 located on the crotch side in the front-rear direction L.

[0045] The absorbent article 10 may have a leg opening 15 with a stretchable leg member 16 in the front-to-back direction L. The leg member 16 extends in the front-to-back direction L and is disposed along the leg opening 15. This allows the leg opening 15 to conform to the wearer's leg circumference. Figure 3 As shown, the absorbent article 10 may have a waist elastic member 17 in the rear waist region S2 that is elastic in the width direction W. The waist elastic member 17 may extend in the width direction W, across the center of the absorbent article 10 in the width direction W.

[0046] The absorbent article 10 has an absorbent body 11 and a hook and loop fastener 90. The absorbent body 11 is composed of at least an absorbent core 50, a skin-friendly surface 41, and a non-skin-friendly surface 42. The hook and loop fastener 90 is disposed in the rear waist region S2 and fixed to the front waist region S1. The hook and loop fastener 90 is provided on both outer sides of the rear waist region S2 in the width direction W. The hook and loop fastener 90 extends outward from the outer edge 11E of the absorbent body 11 in the rear waist region S2 in the width direction W. The hook and loop fastener 90 may have a protrusion 92 extending outward from a portion of the outer side of the hook and loop fastener 90 in the width direction W. The length of the protrusion 92 in the front-rear direction L is shorter than the length of the hook and loop fastener 90 in the front-rear direction L. The protrusion 92 may have a first protrusion 921 and a second protrusion 922 located inside the first protrusion 921 in the front-rear direction L.

[0047] The hook and loop fastener 90 has an engaging portion 96 that engages with the front waist region S1. The engaging portion 96 engages with the front waist region S1, thereby securing the hook and loop fastener 90. The engaging portion 96 may be located at the protrusion 92. The engaging portion 96 has a first engaging portion 961 that engages with the front waist region S1 and a second engaging portion 962 that engages with the front waist region S1 at a position L further in the front-rear direction than the first engaging portion 961. Alternatively, the first engaging portion 961 may be located at the first protrusion 921, and the second engaging portion 962 may be located at the second protrusion 922.

[0048] (3) Body landmarks

[0049] Next, the body marking portion 20 will be described. The absorbent article 10 has a body marking portion 20 indicating the placement position of a part of the wearer's body. The body marking portion 20 is used to install the absorbent article 10 at an appropriate position on the wearer's body. The body marking portion 20 can be visually identified from the skin-side T1 of the absorbent article 10. The body marking portion 20 can be visually identified. For example, in the L*a*b* color system, a body marking portion 20 with a color difference ΔE of 8 or more relative to the surrounding area adjacent to the body marking portion 20 can be visually identified. The body marking portion 20 can be provided, for example, by printing on the absorbent article 10 using an oil-based ink. The body marking portion 20 can also be provided using a colored hot-melt adhesive.

[0050] The body marking portion 20 may have a front edge 20F located at the foremost point in the front-rear direction L and a rear edge 20R located at the rearmost point in the front-rear direction L (see reference). Figure 5 (B). Additionally, the body marking portion 20 may have an innermost inner edge 20I located in the width direction W and an outermost outer edge 20O located in the width direction W (see reference). Figure 5 (B). The maximum length of the body marking portion 20 in the front-rear direction L (i.e., the length in the front-rear direction L from the front edge 20F to the rear edge 20R) can be, for example, 20 mm or more, or 70 mm or less. The maximum width of the body marking portion 20 in the width direction W (i.e., the length in the width direction W from the inner edge 20I to the outer edge 20O) can be, for example, 20 mm or more, or 70 mm or less. The maximum length and / or maximum width of the body marking portion 20 is 20 mm or more, so that the body marking portion 20 can be easily and clearly identified visually. The maximum length and / or maximum width of the body marking portion 20 is 70 mm or less, so that the size of the body marking portion 20 does not need to be increased beyond the necessary placement position relative to the wearer's body, so that the installer can easily grasp the range of the placement position of the wearer's body.

[0051] The body marker 20 at least partially indicates the placement of the wearer's bones and is positioned laterally than the central region CR of the absorbent article 10 in the width direction W. The body marker 20 may indicate the placement of the wearer's iliac crest. In this embodiment, the case where the body marker 20 indicates the placement of the wearer's iliac crest as a bone structure will be described as an example. The body marker 20 may consist of a pair of body markers 20 positioned on both outer sides of the central region CR in the width direction W. Furthermore, the central region CR is either (a) the area between the leak-proof openings 60 in an extended state where the absorbent article 10 does not form wrinkles, from one inner edge 60E to the other inner edge 60E, or (b) the area between the innermost outer edges 50IE and the other outer edge 50IE of the absorbent core 50 in the width direction W (i.e., the area of ​​the shortest width of the absorbent core 50). The central area CR can be the area between the leak-proof openings 60 and the area between the absorbent cores 50, where the width direction W is narrower.

[0052] like Figure 3 As shown, the body marking portion 20 may have a first body marking portion 21 indicating the range of the wearer's bone placement in the front-back direction L. Thus, the body marking portion 20 can indicate the range of the wearer's bone placement in the front-back direction L. The first body marking portion 21 may, for example, be composed of a first portion 211 extending outward in the width direction W along the outer side of the front-back direction L and a second portion 212 extending outward in the width direction W along the outer side of the first portion 211 in the front-back direction L. The range of the wearer's bone placement in the front-back direction L may be indicated by the length from the front edge of the first portion 211 to the rear edge of the second portion 212. The length of the first body marking portion 21 in the front-back direction L may, for example, be 20 mm or more, or 70 mm or less.

[0053] The body marking section 20 may have a second body marking section 22 that graphically represents the mounting location of the absorbent article 10 and the arrangement position of the wearer's bones. Thus, the body marking section 20 can graphically represent the mounting location and the arrangement position of the wearer's bones. The second body marking section 22 may be composed of a graphic consisting of dotted or dashed lines depicting the arrangement position of the wearer's bones on the periphery of the buttocks and hip area (e.g., waist and thigh), which are the mounting locations, such as the back side.

[0054] The body marking section 20 may have a third body marking section 23 that uses text to indicate the wearer's bones that should be positioned at the location indicated by the body marking section 20. Thus, the body marking section 20 can use text to indicate the wearer's bones that should be positioned. In one embodiment, the third body marking section 23 is composed of the character for "lumbar bone". Similarly, when the body marking section 20 indicates the position of the wearer's iliac crest, since the iliac crest is generally less well-known, the third body marking section 23 can be composed of the well-known character for "lumbar bone". The text constituting the third body marking section 23 can be expressed in Japanese, English, or other languages ​​(e.g., Chinese).

[0055] In this embodiment, the body marking portion 20 is composed of a first body marking portion 21, a second body marking portion 22, and a third body marking portion 23. The first body marking portion 21 may be positioned inside the second body marking portion 22 in the width direction W. The third body marking portion 23 may be positioned outside the second body marking portion 22 in the width direction W.

[0056] At least a portion of the body marking portion 20 may be disposed in the rear waist region S2. The body marking portion 20 may be disposed in the rear waist region S2 instead of the crotch region S3. At least a portion of the body marking portion 20 may be disposed (a) at a position rearward of the front edge 90F of the hook and loop fastener 90, (b) at a position rearward of the center of the front-rear direction L of the hook and loop fastener 90, (c) at a position rearward of the front edge 962F of the second engaging portion 962, (d) at a position rearward of the rear edge 962R of the second engaging portion 962, (e) at a position rearward of the front edge 961F of the first engaging portion 961, and (f) at a position rearward of the rear edge 961R of the first engaging portion 961. Additionally, the front edge 20F of the body marking portion 20 can be positioned (a) rearward of the front edge 90F of the hook and loop fastener 90, (b) rearward of the center of the hook and loop fastener 90 in the front-rear direction L, (c) rearward of the front edge 962F of the second engaging portion 962, (d) rearward of the rear edge 962R of the second engaging portion 962, (e) rearward of the front edge 961F of the first engaging portion 961, and (f) rearward of the rear edge 961R of the first engaging portion 961. Additionally, at least a portion (g) of the body marking portion 20 may be positioned rearward of the rear end edge 50R of the absorbent core 50, (h) may be positioned rearward of the front end edge 62F of the front-to-back joint 62 in the rear waist region S2, and (i) may be positioned rearward of the front end edge 17F of the waist elastic member 17. The front end edge 20F (g) of the body marking portion 20 may be positioned rearward of the rear end edge 50R of the absorbent core 50, (h) may be positioned rearward of the front end edge 62F of the front-to-back joint 62 in the rear waist region S2, and (i) may be positioned rearward of the front end edge 17F of the waist elastic member 17. Furthermore, a portion of the body marking portion 20 may be positioned forward of the front end edge 17F of the waist elastic member 17, and the remaining portion of the body marking portion 20 may be positioned rearward of the front end edge 17F of the waist elastic member 17. Alternatively, the body marking portion 20 may be configured entirely within the area extending in the width direction from the hook and loop fastener 90 (a flap extending outward from the absorbent body 11 in the width direction).

[0057] At least a portion of the body marking portion 20 may be positioned forward of the rear end edge 90R of the hook and loop fastener 90. The rear end edge 20R of the body marking portion 20 may be positioned forward of the rear end edge 90R of the hook and loop fastener 90. At least a portion of the body marking portion 20 may be positioned forward of (a) the rear end edge 961R of the first engaging portion 961, (b) the front end edge 961F of the first engaging portion 961, (c) the rear end edge 962R of the second engaging portion 962, (d) the front end edge 962F of the second engaging portion 962, and (e) the rear end edge 17R of the waist elastic member 17. Additionally, the rear end edge 20R of the body marking portion 20 (a) can be positioned forward of the rear end edge 961R of the first engaging portion 961, (b) can be positioned forward of the front end edge 961F of the first engaging portion 961, (c) can be positioned forward of the rear end edge 962R of the second engaging portion 962, (d) can be positioned forward of the front end edge 962F of the second engaging portion 962, and (e) can be positioned forward of the rear end edge 17R of the waist elastic member 17.

[0058] like Figure 1 and Figure 3 As shown, at least a portion of each of the pair of body marker portions 20 may be disposed on the outer side of the inner edge 62E of the front-to-back joint portion 62 located on the width center WC side in the width direction W. The inner edge 20I of the body marker portion 20 may be disposed on the outer side of the inner edge 62E of the front-to-back joint portion 62 in the width direction W. At least a portion of each of the pair of body marker portions 20 may be disposed on the outer side of the upright end edge 61WE in the width direction W in the upright portion 61. For example, the first body marker portion 21 may be disposed on the inner side of the upright end edge 61WE in the width direction W in the upright direction W, and the third body marker portion 23 may be disposed on the outer side of the upright end edge 61WE in the width direction W in the upright direction W. In addition, the inner edge 20I of the body marker portion 20 may be disposed on the outer side of the upright end edge 61WE in the width direction W in the upright portion 61. At least a portion of each of the pair of body marker portions 20 may be positioned outside the outer edge 17E of the waist elastic member 17 in the width direction W. The inner edge 20I of the body marker portion 20 may be positioned outside the outer edge 17E of the waist elastic member 17 in the width direction W.

[0059] At least a portion of each of the pair of body marker portions 20 may be positioned inside the outer edge 11E of the absorbent body 11 in the width direction W. The outer edge 20O of the body marker portion 20 may be positioned inside the outer edge 11E of the absorbent body 11 in the width direction W. In addition, the outer edge 20O (a) of the body marker portion 20 may be positioned inside the outer edge of the top plate 41a in the width direction W, and (b) may be positioned inside the outer edge of the width joint portion 63 in the width direction W.

[0060] Alternatively, in the front-rear direction L, the front edge 20F of the body marking portion 20 may be located in front of the rearmost rearward edge of the locking portion 96 (in this embodiment, the rearward edge 961R of the first locking portion 961), and the rearward edge 20R of the body marking portion 20 may be located in a position rearward of the rearmost rearward edge of the locking portion 96. Or, in the front-rear direction L, the front edge 20F of the body marking portion 20 may be located in a position rearward of the foremost frontward edge of the locking portion 96 (in this embodiment, the front edge 962F of the second locking portion 962).

[0061] The absorbent article 10 may have one or more sheets disposed on the skin-side T1 of the body marker portion 20. These sheets are translucent. For example, the sheets may be made of non-woven fabric to be translucent. In this embodiment, the body marker portion 20 is provided on the non-skin-side of the top sheet 41a. The body marker portion 20 may be provided on either the skin-side of the top sheet 41a or the non-skin-side of the side sheet 41b.

[0062] The absorbent article 10 may include shrinkable members. In this embodiment, the shrinkable members are leg elastic members 16, waist elastic members 17, and leak-proof elastic members 65. These elastic members are fixed to the structural members constituting the absorbent article 10 in an extended state, and therefore have shrinkability. The body marking portion 20 may be disposed in an area that does not overlap with the shrinkable members in the thickness direction T.

[0063] (4) Pad marking section

[0064] Next, the pad marking portion 30 will be described. The absorbent article 10 has a pad marking portion 30 indicating the placement position of the end of the absorbent pad 100 in the front-to-back direction L. The pad marking portion 30 is used to install the absorbent pad 100 in the absorbent article 10 in the appropriate position. The pad marking portion 30 may indicate the placement position of the rear end portion 100R of the absorbent pad 100. The pad marking portion 30 may be composed of a pair of pad marking portions 30 disposed on both outer sides of the width center WC of the absorbent article 10 in the width direction W. The pad marking portion 30 may be disposed in the back waist area S2. Figure 5As shown in Figure B, the front edge 30F of the pad marking portion 30 can be positioned rearward than the front edge 90F of the hook and loop fastener 90. Therefore, when the body marking portion 20 is positioned rearward than the front edge 90F of the hook and loop fastener 90, the body marking portion 20 can be easily visually identified when an installer attaches the absorbent article 10 to which the pad marking portion 30 is mounted. Furthermore, the entire pad marking portion 30 can also be positioned within the area extending in the width direction from the hook and loop fastener 90 (the flap extending outward from the absorbent body 11 in the width direction).

[0065] The pad marking portion 30 is visually identifiable from the skin-side T1 of the absorbent article 10. The pad marking portion 30 can be identified visually. The pad marking portion 30 can be provided, for example, by printing on the absorbent article 10 using an oil-based ink. The pad marking portion 30 may have a front edge 30F located at the foremost point in the front-rear direction L and a rear edge 30R located at the rearmost point in the front-rear direction L (see reference). Figure 5 (B). Additionally, the pad marking portion 30 may have an innermost inner edge 30I located in the width direction W and an outermost outer edge 30O located in the width direction W (see reference). Figure 5 (B). The maximum length of the pad marking portion 30 in the front-rear direction L (i.e., the length of the pad marking portion 30 in the front-rear direction L from the front end edge 30F to the rear end edge 30R) can be, for example, 20 mm or more, or 80 mm or less. The maximum width of the pad marking portion 30 in the width direction W (i.e., the length of the pad marking portion 30 in the width direction W from the inner edge 30I to the outer edge 30O) can be, for example, 20 mm or more, or 70 mm or less.

[0066] like Figure 3As shown, the pad marking portion 30 may have a first pad marking portion 31 indicating the range of the front-rear direction L of the placement position of the end of the absorbent pad 100. Thus, the body marking portion 20 can indicate the range of the front-rear direction L of the placement position of the end of the absorbent pad 100. The first pad marking portion 31 can indicate the range of the front-rear direction L of the placement position of the rear end portion 100R of the absorbent pad 100. The length of the first pad marking portion 31 in the front-rear direction L may be, for example, 20 mm or more, or 80 mm or less. For example, the length of the first pad marking portion 31 in the front-rear direction L may be 20 mm or more and 60 mm or less when the absorbent article 10 is S-size or M-size, and 60 mm or more and 80 mm or less when the absorbent article 10 is L-size. The pad marking portion 30 may have a second pad marking portion 32 that graphically indicates that the pad marking portion 30 is for mounting the absorbent pad 100. Thus, the pad marking portion 30 can graphically indicate that the pad marking portion 30 is for mounting the absorbent pad 100. The pad marking section 30 may have a third pad marking section 33 that indicates in text that the pad marking section 30 is for mounting the absorbent pad 100. Thus, the pad marking section 30 can indicate in text that the pad marking section 30 is for mounting the absorbent pad 100. In this embodiment, the third pad marking section 33 is composed of the text "pad end".

[0067] like Figure 3 As shown, the body marker portion 20 and the pad marker portion 30 can be configured with different designs. The body marker portion 20 and the pad marker portion 30 are separated in the front-rear direction L. The length ML from the body marker portion 20 to the pad marker portion 30 can be longer than half the maximum length of the body marker portion 20 in the front-rear direction L. Therefore, the body marker portion 20 and the pad marker portion 30 can be easily identified separately. In addition, the length ML can be longer than the maximum length of the body marker portion 20 in the front-rear direction L. For example, the length ML can be more than 20 mm apart. In addition, the body marker portion 20 can be located inside the pad marker portion 30 in the front-rear direction L. Therefore, the body marker portion 20 can be visually identified even after the absorbent pad 100 is installed. Furthermore, the length ML can be less than three times the maximum length of the body marker portion 20 in the front-rear direction L. Therefore, when the installation assistant installs the absorbent article 10 with the pad marker portion 30 installed, the body marker portion 20 can be easily visually identified.

[0068] At least a portion of the body marking portion 20 may overlap with the pad marking portion 30 in the front-rear direction L. At least a portion of the pad marking portion 30 may overlap with the body marking portion 20 in the front-rear direction L. Specifically, in the width direction W, the inner edge 20I of the body marking portion 20 may be located inside the width direction W of the outer edge 30O of the pad marking portion 30, and the outer edge 20O of the body marking portion 20 may be located outside the width direction W of the inner edge 30I of the pad marking portion 30. Alternatively, the inner edge 30I of the pad marking portion 30 may be located inside the width direction W of the outer edge 20O of the body marking portion 20, and the outer edge 30O of the pad marking portion 30 may be located outside the width direction W of the inner edge 20I of the body marking portion 20. In this embodiment, in the width direction W, the inner edge 20I of the body marking portion 20 is located inside the inner edge 30I of the pad marking portion 30. Furthermore, the third body marking portion 23 and the third pad marking portion 33, both composed of text, can overlap in the front-back direction L. Thus, the text is arranged along the front-back direction L, allowing the installer to easily grasp the text simply by sliding their gaze along the front-back direction L, reducing the installer's workload.

[0069] (5) Installation method

[0070] Here is an example of how to install the absorbent article 10. First, the installer unfolds the absorbent article 10 and visually identifies the pad marking 30. Using the pad marking 30 as a reference, the installer aligns the absorbent pad 100 with its rear end 100R. (As shown...) Figure 5 As shown, the installer inserts the rear end 100R of the absorbent pad 100 into the non-skin side T2 of the raised portion 61, thereby installing the absorbent pad 100 onto the absorbent article 10.

[0071] Next, the installer attaches the absorbent material 10 to the wearer. The unfolded absorbent material 10 is placed on the back of the side-lying wearer. The installer adjusts the position of the absorbent material 10 based on the body marker 20. Specifically, the installer aligns the wearer's bones with the body marker 20. In this embodiment, the absorbent material 10 is moved to adjust its position so that the body marker 20 overlaps with the iliac crest IC in the width direction W. Even when the wearer's skin protrudes due to the iliac crest IC, the installer can visually identify the position of the iliac crest IC. The installer can also accurately identify the position of the iliac crest IC by touching the wearer's waist.

[0072] Next, as Figure 7As shown, the wearer's body rests on the absorbent material 10, and the wearer lies supine on the absorbent material 10. The body marker 20 is positioned lateral to the central region CR in the width direction W, so that compared to the case where the body marker 20 is only positioned in the central region CR, the body marker 20 is less likely to be obscured by the wearer's body. Even when the wearer lies supine on the absorbent material 10, the installer can easily visually identify the body marker 20. If the wearer notices misalignment between the body marker 20 and the wearer's skeleton, the position of the absorbent material 10 can be adjusted by moving it during installation to align the wearer's skeleton with the body marker 20.

[0073] Next, the front of the absorbent material 10 is fitted to cover the wearer's groin and abdomen. Thus, as... Figure 5 As shown in Figure A, the front waist area S1 of the absorbent article 10 covers the wearer's abdomen. Next, the hook and loop fasteners 90 are secured to the front waist area S1. Figure 5 As shown in Figure B, the wearer engages the second engaging portion 962 with the front waist area S1. The wearer can engage the second engaging portion 962 with the second extending portion 922 extending along the width direction W with the second engaging portion 922 engaged with the front waist area S1, or... Figure 5 As shown in B, the second engaging portion 962 is engaged with the front waist area S1 in a manner that the second protrusion 922 is tilted towards the wearer's waist (so-called tilt fixation). Thereafter, as... Figure 5 As shown in C, the wearer engages the first engaging portion 961 with the front waist area S1. The wearer can engage the first protrusion 921 with the first protrusion 921 extending along the width direction W with the first protrusion 921 engaged with the front waist area S1, or as shown in Figure C. Figure 5 As shown in C, the first protrusion 921 is engaged in the front waist area S1 with the first protrusion 921 tilted towards the wearer's crotch side (so-called tilt fixation). The wearer can also engage the first protrusion 921 in the front waist area S1 by hooking and fastening the hook and fastener 90 to the iliac crest IC. In this way, the absorbent article 10 can be installed on the wearer.

[0074] As described above, in this embodiment, the body marker 20 at least partially indicates the placement of the wearer's bones and is positioned outward from the central region CR of the absorbent article 10 in the width direction W. Compared to the wearer's hips, the position of the wearer's bones is less affected by changes in the wearer's physique and weight. Therefore, even if each wearer has a different body shape, the absorbent article 10 can be properly installed on each wearer by aligning the position of the wearer's bones with the body marker 20 indicating the placement of the wearer's bones. Consequently, the positions of the front and rear ends of the absorbent article 10 are less likely to deviate from their ideal positions, suppressing a deterioration in wearing comfort and / or leakage of excrement. Furthermore, since the body marker 20 is positioned outward in the width direction W, compared to when it is positioned in the central region CR, the body marker 20 is less likely to be obscured by the wearer's body. Therefore, the installation assistant can easily visually identify the body marker 20, and the absorbent article 10 can be easily installed using the body marker 20 as a reference.

[0075] Alternatively, the body marker 20 may indicate the placement position of the wearer's iliac crest IC. In cases where multiple installers of the absorbent article 10 are used in hospitals and / or nursing facilities to install the absorbent article 10 on wearers (especially the elderly), the identification of the buttocks may differ for each installer. Therefore, even if some installers align the wearer's buttocks with the body marker 20 indicating the buttocks' placement, the absorbent article 10 may not be properly installed. Here, the iliac crest IC is typically located in a protruding part near the wearer's waist; therefore, installers can easily identify the location of the iliac crest IC not only visually but also accurately identify it by touching the wearer's waist. Thus, based on accurate identification of the iliac crest IC's location, each installer can align the wearer's iliac crest IC with the body marker 20, enabling proper installation of the absorbent article 10.

[0076] Alternatively, at least a portion of the body marker 20 may be positioned rearward of the front edge 90F of the hook and loop fastener 90 and forward of the rear edge 90R of the hook and loop fastener 90. Thus, when the marker is aligned with the wearer's skeletal structure, and the hook and loop fastener 90 is secured to the front waist region S1, the area between the front edge 90F and the rear edge 90R of the hook and loop fastener 90 remains close to the wearer's body, preventing the wearer's skeletal structure from shifting away from the body marker 20. Therefore, the absorbent article 10 can be properly installed, thus continuously suppressing the deterioration of wearing comfort and / or leakage of excrement.

[0077] Alternatively, at least a portion of the body marker 20 may be positioned forward of the rear end edge 961R of the first engaging portion 961 and rearward of the rear end edge 962R of the second engaging portion 962. This engages the first engaging portion 961 and the second engaging portion 962 in a manner that at least a portion of the body marker 20 is clamped in the front-rear direction L, thus making it less likely for the wearer's skeletal structure to shift from the body marker 20. Consequently, the absorbent article 10 can be properly installed.

[0078] Alternatively, each of the pair of body markers 20 may be positioned at least partially outside the inner edge 62E of the front-to-back joint 62 located on the width center WC side, further outward in the width direction W. Using the pair of body markers 20, the body markers 20 can be visually identified from either the left or right side of the wearer's body. Furthermore, the area inside the inner edge 62E of the front-to-back joint 62 in the width direction W is the area for collecting excrement and is the area where the wearer's body is placed when the absorbent article 10 is installed. Therefore, by positioning the body markers 20 outside the area where the wearer's body is placed (i.e., the area inside the inner edge 62E of the front-to-back joint 62 in the width direction W), the body markers 20 are less likely to be obscured by the wearer's body. Thus, the installer can easily visually identify the body markers 20, and therefore, the absorbent article can be easily installed using the body markers 20 as a reference.

[0079] Alternatively, each of the pair of body markers 20 may be positioned at least partially outside the width-direction W of the raised end edge 61WE of the raised portion 61. Since the raised portion 61 blocks excrement, the area inside the width-direction W of the raised end edge 61WE is an area where the wearer's body is easily supported when the absorbent article 10 is installed. Therefore, by positioning the body markers 20 outside the width-direction W of the area where the wearer's body is easily supported (i.e., the area inside the width-direction W of the raised end edge 61WE), the body markers 20 are less likely to be obscured by the wearer's body. This makes it easier for the installation assistant to visually identify the body markers 20.

[0080] Alternatively, it may have one or more pieces positioned at a position closer to the skin surface T1 than the body marking portion 20. Thus, the body marking portion 20 does not directly contact the wearer's skin, thereby suppressing any impact on the wearer's skin caused by the body marking portion 20 (e.g., ink movement towards the skin, or ink damage to the skin, when the body marking portion 20 is set using ink-formed characters).

[0081] Alternatively, the body marker 20 can be disposed in a region that does not overlap with the shrinking member in the thickness direction T. Therefore, the region where the body marker 20 is disposed is less likely to shrink due to the shrinking of the shrinking member, thus suppressing a decrease in the visual recognizability of the body marker 20.

[0082] Alternatively, the body marking section 20 can indicate the range L of the front-back direction of the wearer's bone placement position. This allows the installer to freely adjust the wearer's bone placement within the range indicated by the body marking section 20. This reduces the mental burden on the installer, who must precisely position the wearer's bones for proper installation. Furthermore, compared to precisely positioning the wearer's bones, the time spent adjusting the bone placement is reduced, thus shortening the installation time. Moreover, when multiple installers install the absorbent article 10 on the wearer, each installer can more easily position the wearer's bones within the range indicated by the body marking section 20 compared to when the body marking section 20 indicates the bone placement position precisely. Therefore, multiple installers can properly install the absorbent article 10.

[0083] Alternatively, the body marking section 20 can graphically represent the mounting location of the absorbent article 10 and the placement of the wearer's bones. This allows the installer to clearly understand the mounting location and the placement of the wearer's bones using the graphics, making it easier to understand the meaning of the body marking section 20 and facilitating the installation of the absorbent article using the body marking section 20 as a reference.

[0084] Alternatively, the body marking section 20 can use text to indicate the wearer's skeleton that should be positioned at the location indicated by the body marking section 20. Thus, an installation assistant who has visually recognized the text can use the body marking section 20 to understand the correct placement of the wearer's skeleton, thereby reducing the possibility of the installation assistant incorrectly placing other parts of the wearer's body.

[0085] Alternatively, the body marker 20 and the pad marker 30 can be separated in the front-to-back direction L. This makes it easier for the wearer to distinguish between the body marker 20 and the pad marker 30, allowing them to identify each other separately. Consequently, it reduces the likelihood of the wearer's bones misaligning with the position of the pad marker 30.

[0086] Alternatively, at least a portion of the body marker 20 may overlap with the pad marker 30 in the front-rear direction L. Therefore, when the pad marker 30 is found, the body marker 20 can be found by moving the line of sight in the front-rear direction L, making it easy for the installation assistant to locate the body marker 20. Consequently, the installation assistant can easily install the absorbent article using the body marker 20 as a reference.

[0087] Alternatively, the body marker 20 and the pad marker 30 can be positioned further rearward than the front edge 90F of the hook and loop fastener 90. This makes it easier for the body marker 20 to come into view when the pad marker 30 is discovered, allowing the installer to easily locate it. Consequently, the installer can easily install the absorbent material using the body marker 20 as a reference.

[0088] (6) Other implementation methods

[0089] The present invention has been described in detail above using the embodiments described above. However, it will be apparent to those skilled in the art that the present invention is not limited to the embodiments described in this specification. The present invention can be implemented in modified and altered forms without departing from the spirit and scope of the invention as defined by the claims. Therefore, the description in this specification is for illustrative purposes only and does not have any limiting meaning for the present invention.

[0090] In the above-described embodiment, the body marking section 20 indicates the placement of the wearer's iliac crest, which is part of the wearer's skeleton, but is not limited thereto. The body marking section 20 may also indicate the placement of any of the wearer's skeletons, such as the sacrum, ilium, lumbar vertebrae (e.g., the 3rd, 4th, and 5th lumbar vertebrae, etc.), pubis, coccyx, greater trochanter, etc.

[0091] Furthermore, the first body marking portion 21 can, like the first pad marking portion 31, use arrows to indicate the range of the front-back direction L of the wearer's bone placement position. The first pad marking portion 31 can, like the first body marking portion 21, be composed of a first portion extending outward in the front-back direction L and inward in the width direction W, and a second portion extending outward in the width direction W from the first portion 211 outward in the front-back direction L.

[0092] In the above-described embodiments, the absorbent article 10 may have marking portions other than the body marking portion 20 and the pad marking portion 30. For example, the absorbent article 10 may have marking portions that guide the fixing position of the hook and loop fastener 90. This also allows for the tilting and fixing of the hook and loop fastener 90.

[0093] In the above-described embodiment, the absorbent article 10 has a pad marking portion 30, but is not limited thereto. The absorbent article 10 may not have the pad marking portion 30. The absorbent pad 100 may also be used without being attached to the absorbent article 10.
