Description

[Technical field]

[0001] The present invention relates to an absorbent article, and more particularly to an absorbent article having a fastening member. [Background technology]

[0002] In recent years, the demand for disposable absorbent articles has been expanding due to the aging of the population. Disposable absorbent articles are used, for example, by infants, the elderly, and people receiving care in hospitals, nursing homes, or at home. In addition, for convenience and cost reasons, pad-type absorbent articles (also called "urinary pads" or "innerwear") are often used by attaching them to the inside of tape-type or pants-type absorbent articles, diaper-like covers, or reusable underwear (also called "outerwear"). In order to stably attach the innerwear to the inside of the outerwear, a urine pad having a fastening member on the opposite side of the skin-facing side (also called "non-skin-facing side") has also been proposed. However, the fastening member may be placed on the non-skin-facing side of the urine pad (for example, on the back sheet) and may stick to an unintended location. For example, when a folded urine pad is stored in a package, the fastening member on the non-skin-facing side may adhere to a member such as a nonwoven fabric of another adjacent folded urine pad, and there is a risk of damaging the member if the attached fastening member is forcibly removed. In such a case, unintentional attachment of the fastening member causes stress and trouble for the caregiver or user.

[0003] Patent Document 1 discloses an absorbent article in which an engaging member is disposed on a non-skin-facing surface at a position in a first longitudinal region that overlaps with a second longitudinal region in the thickness direction and is not exposed on the outer surface of the absorbent article in a folded state. With this configuration, it is possible to prevent the folded absorbent articles from adhering to other absorbent articles when they are taken out one by one from a container. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2018-064718 Summary of the Invention [Problem to be solved by the invention]

[0005] In the absorbent article of Patent Document 1, both the top sheet and the back sheet are made of nonwoven fabric, and in the folded state, the engaging member is engaged with the nonwoven fabric that forms the skin-facing surface or the non-skin-facing surface. Therefore, when unfolding the absorbent article, it may be difficult for elderly caregivers and users, especially those with weak fingers, to remove the engaging member that has engaged with the nonwoven fabric. In addition, if force is applied when removing the engaging member that has engaged with the nonwoven fabric, the nonwoven fabric may be damaged. Furthermore, there is a risk that the engaging member that has finally been removed may unintentionally adhere to the nonwoven fabric again.

[0006] The present invention has been made in consideration of the above-mentioned problems, and aims to provide an absorbent article that reduces the possibility of a fastening member arranged on the non-skin-facing side of the absorbent article unintentionally adhering to an adjacent member such as a nonwoven fabric. [Means for solving the problem]

[0007] The absorbent article of the present invention has a main body having a top sheet, a back sheet, and an absorbent core disposed between them, and a fastening member provided on the back sheet of the main body, the back sheet being formed of a moisture permeable material. The main body has a front region, a crotch region, and a rear region in the longitudinal direction. In at least one of the front region and the rear region in the longitudinal direction of the absorbent article, an absorbent core non-existence portion where no absorbent core is present is provided. The fastening member is provided at a position overlapping the absorbent core in the thickness direction, and has a first long side and a second long side in the short direction perpendicular to the longitudinal direction of the absorbent core, and the first long side of the fastening member is closer to the absorbent core non-existence portion than the second long side. In the longitudinal direction, the length of the absorbent core non-existence portion is longer than the length from the longitudinal end of the absorbent core to the second long side of the fastening member. Effect of the Invention

[0008] According to the present invention, the back sheet provided with the fastening member is formed from a moisture-permeable material, and the length of the non-absorbent core portion in the longitudinal direction is made longer than the length from the longitudinal end of the absorbent core to the second long side of the fastening member, thereby making it possible to provide an absorbent article that reduces the possibility of the fastening member arranged on the non-skin side of the absorbent article unintentionally adhering to materials such as nonwoven fabric. [Brief description of the drawings]

[Figure 7] 1 shows an example of a state of a folding line when a fastening member provided on an absorbent article is covered by an absorbent core-free portion. [Figure 8] FIG. 2 is a plan view of an absorbent article having fastening members provided in the front region and the rear region as a second embodiment of the present invention. [Figure 9] 1 shows an example of a package in which an absorbent article is contained in a packaging bag. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] FIG. 1 shows a plan view of an absorbent article 100 as one embodiment of the present invention, as seen from the skin-facing side. FIG. 1 shows the skin-facing side of the absorbent article 100 when it is spread out flat. FIG. 2 shows an example of a plan view of the absorbent article 100 shown in FIG. 1 as seen from the non-skin-facing side. FIG. 2 shows the non-skin-facing side of the absorbent article 100 when it is spread out flat. The absorbent article 100 has a main body portion 1 having a top sheet 2, a back sheet 3, and an absorbent core 5 disposed therebetween, and a fastening member 8 provided on the back sheet 3 of the main body portion 1. The back sheet 3 is formed of a material having moisture permeability. The main body portion 1 has, in order from the longitudinal direction, a front region 20, a crotch region 30, and a rear region 40. In at least one of the front region 20 and the rear region 40 in the longitudinal direction of the absorbent article 100, an absorbent core non-existent portion 7 where the absorbent core 5 is not present is provided in the outer region of the absorbent core 5. The fastening member 8 is provided at a position overlapping with the absorbent core 5 in the thickness direction. It has a first long side 8a and a second long side 8b in the short direction perpendicular to the longitudinal direction of the absorbent core 5. The first long side 8a of the fastening member 8 is located closer to the non-absorbent core portion 7 than the second long side 8b. In the longitudinal direction of the absorbent article 100, the length of the non-absorbent core portion 7 is longer than the length from the longitudinal end 5a of the absorbent core 5 to the second long side 8b of the fastening member 8. The back sheet 3 on which the fastening member 8 is provided is formed of a material such as a moisture-permeable plastic film rather than a nonwoven fabric, so that the fastening member 8 is unlikely to engage with the back sheet 3 unintentionally. In addition, in the longitudinal direction, the length 7c of the non-absorbent core portion 7 is longer than the length from the longitudinal end 5a of the absorbent core 5 to the second long side 8b of the fastening member 8, so that the back sheet 3, which also constitutes the non-skin facing side of the non-absorbent core portion 7, is arranged around the fastening member 8, allowing it to be distanced from members that are more likely to engage, such as nonwoven fabrics. Furthermore, for example, since the non-absorbent core portion 7 is thinner than the absorbent core 5, it is more likely to bend at the longitudinal end portion 5a of the absorbent core 5. However, even if it is bent, the fastening member is covered by the back sheet 3 which also forms the non-skin facing side of the non-absorbent core portion 7, so that the possibility of it adhering to a member which is easily engaged can be further reduced.

[0011] The absorbent article 100 can be used as an innerwear as an auxiliary device that is placed inside (i.e., on the wearer's side) of an outerwear worn by a wearer and receives excrement from the wearer. In the following description, the direction of the arrow X in Fig. 1 is referred to as the "longitudinal direction" of the absorbent article 100, and the direction of the arrow Y perpendicular to the longitudinal direction is referred to as the "transverse direction" of the absorbent article 100.

[0012] As shown in the figure, the fastening member 8 is disposed on the backsheet 3 of the absorbent article 100 in at least one of the front region 20 and the rear region 40 of the absorbent article 100. In FIG. 2, as an example, the fastening member 8 is disposed only in the front region 20. In this case, it is sufficient that the length 7c of the absorbent core-free part 7 in at least the front region 20 in the longitudinal direction is set longer than the length 8c from the longitudinal end 5a of the absorbent core 5 to the second long side 8b of the fastening member 8.

[0013] FIG. 3 shows an example of a cross section of the absorbent article 100 shown in FIG. 1 taken along line III-III. The absorbent article 100 includes a top sheet 2, a back sheet 3, and an absorbent core 5 disposed between the top sheet 1 and the back sheet 3. The absorbent core 5 includes at least one of a fiber aggregate, a mixture of a fiber aggregate and a water-absorbent resin, and a sheet-like absorbent core having a water-absorbent resin between nonwoven fabrics. As shown in the figure, the absorbent core 5 may have a plurality of absorbent layers, and the number of absorbent layers may be appropriately determined depending on the application. The shape (planar shape) of the absorbent core 5 is not particularly limited except as described above. The shape of the absorbent core 5 may be appropriately determined depending on the application, and may be, for example, a substantially rectangular shape, an hourglass shape, a gourd shape, or a shuttlecock shape. When the absorbent core 5 has multiple absorbent layers, the shapes (planar shapes) and / or sizes of the absorbent layers may be different from one another, but if the ends of the absorbent layers are aligned at the longitudinal end 5a of the absorbent core 5, there is an advantage that the absorbent core 5 can be easily folded when at least one fastening member is covered with the absorbent core-free part 7 and folded. In addition, when the end 5a of the absorbent core 5 is convex rather than linear as shown in Figures 1 and 2, the apex position of the convex shape can be the longitudinal end 5a of the absorbent core 5.

[0014] FIG. 4 shows an example of an embodiment of the absorbent article 100 in which the fastening member 8 provided on the back sheet 3 is covered by the absorbent core absent portion 7. FIG. 4 is a diagram showing the absorbent article being folded in three. The absorbent article is folded so that the fastening member 8 is located inside the three folds in the folded state. The length 7c of the absorbent core absent portion 7 in the longitudinal direction is set longer than the length 8c from the end 5a of the absorbent core 5 to the second long side 8b of the fastening member 8, so that the fastening member 8 located inside the three folds is covered by the absorbent core absent portion 7. In the folded state of the absorbent article 100, the fastening member 8 is entirely covered by the back sheet 3. Since the fastening member 8 is not located on the outer surface of the absorbent article 100, and there is no concern that the fastening member 8 will adhere to the back sheet 3 of another adjacent absorbent article 100 when stored, it is possible to provide an absorbent article 100 that is easy to store in the packaging bag 50 and easy to handle.

[0015] FIG. 5 shows another example of the absorbent article 100 folded in three. FIG. 5 shows the absorbent article 100 folded in three, with the fastening member 8 positioned on the outer surface of the folded absorbent article 100. The back sheet 3 is formed of a moisture-permeable material with which the fastening member 8 is difficult to engage, so that when a plurality of absorbent articles 100 folded in three are stored in a packaging bag 50, the fastening member 8 can be opposed to the back sheet 3 of another absorbent article 100 arranged adjacently, thereby suppressing the possibility of the fastening member 8 unintentionally adhering to another member. In addition, since the length 7c of the absorbent core non-existence portion 7 in the longitudinal direction is set longer than the length 8c from the end portion 5a of the absorbent core 5 to the second long side 8b of the fastening member 8, the absorbent core non-existence portion 7 may be folded outward to cover the fastening member 8. By folding in three in such a manner, the fastening member 8 can be prevented from unintentionally adhering to another member.

[0016] Fig. 6 shows an example of fold lines when the absorbent article 100 is folded in thirds. When folding in thirds, the top sheets 2 are folded inward at the first longitudinal fold line 9a and the second longitudinal fold line 9b so that they face each other. Furthermore, by folding in thirds from one end in the longitudinal direction at the first transverse fold line 10a and the second transverse fold line 10b so that the top sheets 2 face each other, the absorbent article 100 can be folded in the arrangement of the fastening members 8 shown in Fig. 4 or Fig. 5. The fastening members 8 arranged on the back sheet 3 are located between the first longitudinal fold line 9a and the second longitudinal fold line 9b.

[0017] Fig. 7 shows an example of the fold line configuration in an example of folding with the fastening member 8 arranged as shown in Fig. 4. The fastening member 8 arranged on the back sheet 3 is located between the first longitudinal fold line 9a and the second longitudinal fold line 9b. Also, the second transverse fold line 10b is folded along the edge of the longitudinal end 5a of the absorbent core 5 of the main body portion 1. If the absorbent article 100 is folded along normal three-fold fold lines, the fastening member 8 provided on the absorbent article 100 is covered by the absorbent-core-free portion 7, so there is no need to fold along an additional fold line.

[0018] Fig. 8 shows an example of an embodiment in which fastening members are provided in the front region 20 and the rear region 40 of the absorbent article 100. A first fastening member 8A is disposed in the front region 20, and a second fastening member 8B is disposed in the rear region 40. Both the first fastening member 8A and the second fastening member 8B are disposed on the back sheet 3 formed of a moisture-permeable member at positions overlapping with the absorbent core 5 in the thickness direction. The direction of the arrow X in Fig. 8 is referred to as the "longitudinal direction" of the absorbent article 200, and the direction of the arrow Y perpendicular to the longitudinal direction is referred to as the "transverse direction" of the absorbent article 200.

[0019] 9 shows an example of an embodiment of a package 300 in which the absorbent article 100 or the absorbent article 200 is contained in a packaging bag 50. The absorbent article 100 or the absorbent article 200 is arranged in a folded state in the left-right direction. Furthermore, as shown in the figure, the absorbent article 100 or the absorbent article 200 may be stacked in the height direction and contained in the packaging bag 50. As described above, whether the absorbent article has one fastening member 8 or multiple fastening members 8, according to the embodiment of the present invention, it is possible to provide an absorbent article that suppresses the possibility of unintentional adhesion to members such as nonwoven fabric, or a package 300 including multiple absorbent articles.

[0020] (Top sheet) The top sheet is usually the sheet placed closest to the wearer in the absorbent article and serves as the skin contact surface, and quickly captures the wearer's bodily fluids and transfers them to the absorbent core. The top sheet is a liquid-permeable sheet material, and for example, a nonwoven fabric made of hydrophilic fibers can be used. Examples of nonwoven fabrics used as the top sheet include point-bonded nonwoven fabrics, air-through nonwoven fabrics, spunlace nonwoven fabrics, and spunbonded nonwoven fabrics, and cellulose, rayon, cotton, and the like are usually used as hydrophilic fibers forming these nonwoven fabrics. Note that the top sheet may be a liquid-permeable nonwoven fabric made of hydrophobic fibers (for example, polypropylene, polyethylene, polyester, polyamide, nylon) whose surfaces have been hydrophilized with a surfactant.

[0021] (Back seat) The back sheet is a sheet disposed on the outermost side of the absorbent article, and prevents body fluids and the like from leaking out to the outside. As the liquid-impermeable sheet used for the back sheet, for example, a water-repellent and / or liquid-impermeable nonwoven fabric (for example, spunbond nonwoven fabric, meltblown nonwoven fabric, SMS (spunbond-meltblown-spunbond) nonwoven fabric) formed of hydrophobic fibers (for example, polypropylene, polyethylene, polyester, polyamide, nylon) or a water-repellent and / or liquid-impermeable plastic film is used, and prevents body fluids that reach the liquid-impermeable sheet from seeping out to the outside of the absorbent article. When a plastic film is used for the liquid-impermeable sheet, it is preferable to use a plastic film having moisture permeability (breathability) from the viewpoint of preventing stuffiness and improving the comfort of the wearer. In addition, a sheet material such as a paper sheet may be placed between the plastic film and the absorbent core to further impart diffusion properties and shape stability. Although a laminate of a nonwoven fabric and a plastic film may be used, in the embodiment of the present invention, it is preferable that the plastic film is disposed on the non-skin facing side of the backsheet.

[0022] (Side seat) Side sheets extending in the longitudinal direction of the absorbent article may be joined to both widthwise edges of the top sheet. The side sheets may be made of, for example, a liquid-impermeable plastic film or a water-repellent nonwoven fabric. The inner end of the side sheet in the widthwise direction of the absorbent article may be provided with an elastic member for standing. The elastic member arranged at the inner end of the side sheet causes the inner end of the side sheet to stand up toward the wearer's skin due to the contraction force of the elastic member when the absorbent article is in use, thereby preventing lateral leakage of excrement such as urine.

[0023] (Absorbent core) The absorbent core may contain at least one layer of fiber assembly to absorb and retain body fluids. When the absorbent core contains a fiber assembly, the shape retention of the absorbent core is increased, and a path for body fluids is secured. The fiber assembly is, for example, a fiber assembly containing at least one type of fiber selected from pulp fibers, cellulose fibers, rayon, acetate fibers, heat-fusible fibers, etc. As the heat-fusible fibers, for example, polyolefin fibers such as polyethylene and polypropylene, polyester fibers, composite fibers, etc. are used. The absorbent core may be formed only from a fiber assembly. The molded body may have a covering sheet such as tissue paper, thin paper, a core wrap sheet, or a liquid-permeable nonwoven fabric sheet. When the absorbent core is composed of a plurality of absorbent layers, the above-mentioned sheet may be disposed between the absorbent layers. The absorbent core may contain a water-absorbent resin, as described later.

[0024] In addition to the fiber aggregate, the absorbent core may contain a water-absorbing resin such as SAP (Super Absorbent Polymer) and / or SAF (Super Absorbent Fiber). As the water-absorbing resin, a polyacrylic acid-based, polyaspartic acid-based, cellulose-based, starch-acrylonitrile-based, or other water-absorbing resin may be used.

[0025] The absorbent core may be a sheet-like absorbent core, may have a sheet-like absorbent layer as a part of the absorbent core, or may have multiple sheet-like absorbent layers. The sheet-like absorbent core is formed by having a water-absorbent resin between nonwoven fabrics without including pulp fibers. The sheet-like absorbent core can achieve a high absorption capacity because it has a water-absorbent resin between the nonwoven fabrics. In addition, since it does not include pulp fibers, bulkiness is suppressed and it can be formed thin. The absorbent core may include an absorbent layer including a fiber aggregate and a sheet-like absorbent core.

[0026] (Fastening member) The fastening member is a member provided on the non-skin facing side of the absorbent article and capable of fastening to the skin facing side of the outerwear. Examples of the fastening member include a resin hook-and-loop fastener having a large number of hook elements and an adhesive member. After the fastening member is attached to and / or engaged with another part, it can be separated again and can be attached and / or engaged repeatedly.

[0027] The fastening member is provided at a position overlapping the absorbent core in the thickness direction, and has a first long side and a second long side in the short direction of the absorbent article. The first long side is on the outer side of the absorbent article in the longitudinal direction, and the second long side is on the inner side of the absorbent article in the longitudinal direction.

[0028] In an embodiment of the present invention, an absorbent core-free portion where no absorbent core is present is provided on the outside of the absorbent core in at least one of the front and rear regions of the absorbent article. The longitudinal length of the absorbent core-free portion is preferably longer than the length from the end of the absorbent core in the longitudinal direction to the second long side of the fastening member. With this configuration, when the absorbent article is folded and stored in a packaging bag and when the absorbent article is removed from the packaging bag, the fastening member is covered by the absorbent core-free portion, so that the fastening member can be prevented from unintentionally adhering to other members.

[0029] The fastening members may be provided in both the front and rear regions of the absorbent article. By providing the fastening members in both the front and rear regions, it is possible to further prevent the inner from shifting when used in combination with the outer. Even if the fastening members are provided in both the front and rear regions, the fastening members are covered by the absorbent core-free portion and / or the back sheet formed of a moisture-permeable member, so that it is possible to prevent the fastening members from unintentionally adhering to other members when the absorbent article is folded and stored in a packaging bag and when the absorbent article is removed from the packaging bag.

[0030] Although the absorbent article according to the embodiment of the present invention is not particularly limited, it is preferable that the absorbent article is a large innerwear having a longitudinal length of 530 mm or more and 650 mm or less. Compared with a small innerwear, a large innerwear is more likely to slip when the wearer moves. Therefore, by providing a fastening member in at least one of the front region and the rear region of the large innerwear, it is possible to fix it to the outerwear, thereby suppressing slippage and preventing leakage of urine, etc. In order to further prevent slippage, a fastening member may be provided not only in at least one of the front region and the rear region but also in the crotch region.

[0031] (Storage of absorbent articles) The absorbent article is preferably stored in a folded state in the package. Examples of the folded shape of the absorbent article include folding in two, folding in three, folding in four, etc. In Figs. 4 to 7 of this embodiment, folding in three is exemplified. The folding method is such that the top sheet is folded so as to face each other at a first longitudinal fold line and a second longitudinal fold line extending in the longitudinal direction. Furthermore, the top sheet is folded so as to face each other at a first transverse fold line and a second transverse fold line extending in the transverse direction, and the article is folded in thirds in the longitudinal direction by the first transverse fold line and the second transverse fold line. The fastening member disposed on the backsheet is preferably located between the first longitudinal fold line and the second longitudinal fold line, and the second transverse fold line is preferably folded along an edge of the longitudinal end of the absorbent core of the main body portion.

[0032] (packaging) The package contains two or more absorbent articles. In this case, the fastening member provided on the back sheet is covered with the absorbent core-free portion and / or the back sheet formed of a moisture-permeable material, thereby preventing the fastening member from unintentionally adhering to other members or adjacent absorbent articles.

[0033] Furthermore, the configuration of the present invention may be used not only in the innerwear described using the embodiment, but also in other absorbent articles having fastening members.

[0034] The configurations in the above-described embodiment and each of the modified examples may be combined as appropriate as long as they are not mutually inconsistent. [Explanation of symbols]
