[Technical Field]
[0001] The present invention relates to an absorbent article package. [Background Art]
[0002] Sanitary napkins, disposable diapers, panty liners, incontinence pads, fecal incontinence pads, breast milk pads and the like are known as absorbent articles. Such absorbent articles are desired to be more flexible products in order to improve comfort during wear. For example, Patent Document 1 discloses a sanitary napkin in which flexibility and fitting properties are improved by forming a low basis weight portion over the entire area of an absorbent core. [Prior Art Literature] [Patent Literature]
[0003] [Patent Document 1] Japanese Unexamined Patent Publication No. 2012-245130 [Summary of the Invention] [Problems to be Solved by the Invention]
[0004] However, as in the sanitary napkin described in Patent Document 1, as a low basis weight portion is provided in a wide range of the absorbent core to increase the flexibility of the sanitary napkin, the comfort during wear improves. Nevertheless, when the sanitary napkin is in a packaged state, external force may deform the sanitary napkin or crush the low basis weight portion provided for increasing flexibility, which may give a feeling of discomfort to the wearer in the worn state.
[0005] The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide an absorbent article package that facilitates making the absorbent article flexible and easily improves comfort when the absorbent article is worn. [Means for Solving the Problems]
[0006] The main invention for achieving the above objective is an absorbent article and a packaging material for packaging the absorbent article, wherein the absorbent article, in an unfolded state, has a longitudinal direction, a width direction and a thickness direction, and is folded at at least one folding portion along the width direction, the absorbent article having an absorbent core having liquid absorbent fibers, a skin-side sheet portion located on the skin side of the absorbent core, and a non-skin-side sheet portion located on the non-skin side of the absorbent core, the absorbent core having a low-basis-weight portion where the basis weight of the liquid absorbent fibers is lower than that of the surrounding area, the low-basis-weight portion having one low-basis-weight portion on one side in the width direction, and the other The absorbent article packaging is characterized by having a low basis weight section on one side, wherein in the unfolded state, the low basis weight section on one side and the low basis weight section on the other side are arranged intermittently along the longitudinal direction, the front end of the low basis weight section located furthest forward is inclined with respect to the longitudinal direction, the rear end of the low basis weight section located furthest rear is inclined with respect to the longitudinal direction, and having a pair of compressed sections along the longitudinal direction in which the skin-side sheet section and the non-skin-side sheet section are compressed in the thickness direction, and the compressed sections have a portion that overlaps with the low basis weight section when viewed in the thickness direction. Other features of the present invention will be made clearer by description in this specification and the accompanying drawings. [Effects of the Invention]
[0007] According to the present invention, it is possible to create an absorbent article packaging that makes it easier to make absorbent articles flexible and improves the comfort of the absorbent articles when worn. [Brief explanation of the drawing]

[Figure 11] This figure schematically shows the cross-section along the line N-N in Figure 3. [Modes for carrying out the invention]
[0009] The following matters become clear from this specification and the accompanying drawings: Embodiment 1 comprises an absorbent article and a packaging material for packaging the absorbent article, wherein the absorbent article, in an unfolded state, has a longitudinal direction, a width direction and a thickness direction, and is an absorbent article package folded at at least one fold portion along the width direction, the absorbent article having an absorbent core having liquid absorbent fibers, a skin-side sheet portion located on the skin side of the absorbent core, and a non-skin-side sheet portion located on the non-skin side of the absorbent core, the absorbent core having a low basis weight portion where the basis weight of the liquid absorbent fibers is lower than that of the surrounding area, the low basis weight portion having one low basis weight portion on one side in the width direction and the other low basis weight portion on the other side The absorbent article packaging is characterized by having a weight section, wherein in the unfolded state, the one low-basis-weight section and the other low-basis-weight section are each arranged intermittently along the longitudinal direction, the front end of the foremost low-basis-weight section is inclined with respect to the longitudinal direction, the rear end of the rearmost low-basis-weight section is inclined with respect to the longitudinal direction, and having a pair of compressed sections along the longitudinal direction in which the skin-side sheet section and the non-skin-side sheet section are compressed in the thickness direction, and the compressed sections have a portion that overlaps with the low-basis-weight section when viewed in the thickness direction.
[0010] While greater flexibility of absorbent materials improves comfort during wear, greater flexibility also increases the risk of deformation of the absorbent material in its packaging. According to Embodiment 1, the low-basis-weight portion provided in the absorbent core makes the absorbent material more flexible, and the presence of a compression portion in the thickness direction, overlapping with the low-basis-weight portion, reduces the risk of the low-basis-weight portion being crushed. Furthermore, the low-basis-weight portions are intermittently arranged in the longitudinal direction, and there are portions between adjacent low-basis-weight portions in the longitudinal direction where the basis weight of the liquid absorbent fiber is higher than that of the low-basis-weight portion. This makes it easier to return the deformed low-basis-weight portion to its original shape even if it is crushed by force applied from the outside in the width direction in the packaging. Therefore, even if force is repeatedly applied from the outside in the width direction in the packaging, the risk of the low-basis-weight portion being completely crushed is reduced. As a result, it becomes easier to improve the comfort of the absorbent material when worn. Furthermore, the front and rear ends of the low-basis-weight section are inclined with respect to the longitudinal direction, which makes it easier for the force applied to the absorbent article packaging from the outside in the width direction to be absorbed and dispersed at both ends in the longitudinal direction of the low-basis-weight section. In addition, it also makes it easier to disperse the force applied to the absorbent article packaging from the outside in the longitudinal direction.
[0011] Embodiment 2 is an absorbent article packaging according to Embodiment 1, having a portion of the low basis weight section that has zero basis weight.
[0012] According to Embodiment 2, the flexibility of the absorbent article packaging is improved, and the skin-side sheet portion and the non-skin-side sheet portion at the compressed area are more easily joined. This reduces the risk of the low-basis-weight portion being crushed in the absorbent article packaging, while also reducing the creasing of the absorbent article when worn, thus reducing discomfort during wear.
[0013] Aspect 3 is the absorbent article package according to Aspect 1 or 2, wherein in the deployed state, the one-side low basis weight portion and the other-side low basis weight portion are each configured such that the front end of the low basis weight portion located most frontward is spaced apart from the front edge of the absorbent core, and the rear end of the low basis weight portion located most rearward is spaced apart from the rear edge of the absorbent core.
[0014] According to Aspect 3, the risk of deformation of the absorbent core in the packaged state can be reduced. Further, since portions having a higher basis weight of liquid-absorbent fibers than the low basis weight portions are provided on the front side and the rear side of the low basis weight portions respectively, even when a force is applied in the longitudinal direction in the packaged state and the worn state and the absorbent core is deformed, the shape of the absorbent core is easily restored. This can reduce the risk that the low basis weight portions provided on the absorbent core are worn in a crushed state, and facilitates improving the comfort of the absorbent article in the worn state.
[0015] Aspect 4 is the absorbent article package according to any one of Aspects 1 to 3, wherein in the deployed state, the absorbent article has a pair of wing portions extending to both outer sides in the width direction, wing adhesive portions coated with an adhesive are each provided on the non-skin side surfaces in the thickness direction of the pair of wing portions, the one-side low basis weight portion and the other-side low basis weight portion each have a central low basis weight portion including a portion overlapping the wing adhesive portion in the longitudinal direction, and both end portions of the central low basis weight portion in the longitudinal direction are each inclined inward with respect to the longitudinal direction.
[0016] According to aspect 4, the position overlapping the wing adhesive portion in the longitudinal direction is a portion that abuts against the excretory opening in the worn state. Since both ends of the central low-basis-weight portion in the longitudinal direction are each inclined inward in the longitudinal direction, when a force is applied from the outside in the width direction in the packaged state and the worn state, the force applied to the central low-basis-weight portion can be easily buffered first between the both ends in the longitudinal direction. This makes it easy to maintain the shape of the portion of the absorbent article that abuts against the excretory opening, and can reduce the risk that both ends of the central low-basis-weight portion in the longitudinal direction will be crushed.
[0017] Aspect 5 is the absorbent article package according to any one of aspects 1 to 3, wherein in the unfolded state, the absorbent article has a pair of wing portions extending to both outer sides in the width direction, wing adhesive portions coated with an adhesive are respectively provided on non-skin side surfaces in the thickness direction of the pair of wing portions, the one side low-basis-weight portion and the other side low-basis-weight portion each have a central low-basis-weight portion including a portion overlapping the wing adhesive portion in the longitudinal direction, and both ends of the central low-basis-weight portion in the longitudinal direction are each inclined outward with respect to the longitudinal direction.
[0018] According to aspect 5, the position overlapping the wing adhesive portion in the longitudinal direction is a portion that abuts against the excretory opening in the worn state. Since both ends of the central low-basis-weight portion in the longitudinal direction are each inclined inward in the longitudinal direction, when a force is applied from the outside in the width direction in the packaged state and the worn state, the force applied to the central low-basis-weight portion can be easily buffered first at the both ends in the longitudinal direction. Accordingly, the risk that the portion between both ends of the central low-basis-weight portion in the longitudinal direction will be crushed can be reduced.
[0019] Aspect 6 is the absorbent article package according to any one of aspects 1 to 5, wherein in the unfolded state, when viewed in the thickness direction, at least one of the folded portions does not overlap the compressed portion.
[0020] According to embodiment 6, the folded portion that does not overlap with the compressed portion when viewed in the thickness direction can make the folded portion of the absorbent article packaging softer than the folded portion that overlaps with the compressed portion when viewed in the thickness direction, making it easier to fold the absorbent article packaging at the folded portion and making it easier to maintain the folded shape of the absorbent article packaging in its packaged state.
[0021] Embodiment 7 is an absorbent article packaging according to any one of Embodiments 1 to 6, wherein in the unfolded state, the absorbent article has a pair of wing portions extending outward on both sides in the width direction and a middle-high portion that is thicker than the surrounding area, and each of the pair of wing portions has a wing adhesive portion on the non-skin side in the thickness direction to which adhesive is applied, and at least a part of the middle-high portion is located at a position overlapping with the wing adhesive portion in the longitudinal direction and between the pair of low-basis-weight portions in the width direction.
[0022] According to embodiment 7, the position in the longitudinal direction that overlaps with the wing adhesive portion is the part that comes into contact with the excretory opening when worn. Therefore, the low basis weight portions on both sides in the width direction of the mid-high portion make it easier to buffer external forces in the packaged state, make it easier to maintain the shape of the mid-high portion provided between the pair of low basis weight portions, and make it easier to absorb excrement.
[0023] Embodiment 8 is an absorbent article packaging according to Embodiment 7, wherein, in the unfolded state, the absorbent article has a front compression section in front of the pair of compression sections and a rear compression section behind the pair of compression sections, the front compression section and the rear compression section are portions in which the skin-side sheet portion and the non-skin-side sheet portion are compressed in the thickness direction, and in the packaged state, when viewed in the thickness direction, the front compression section and the rear compression section each have portions that overlap with the middle-high section.
[0024] According to embodiment 8, in the packaged state, the low basis weight portions provided on both sides in the width direction of the mid-high portion cushion the force, and the highly rigid front and rear compression portions have portions that overlap with the mid-high portion when viewed in the thickness direction, making it easier to maintain the shape of the mid-high portion and to absorb excrement.
[0025] Embodiment 9 is an absorbent article packaging according to any one of Embodiments 1 to 8, wherein the absorbent article has a back sheet located on the non-skin side of the non-skin side sheet portion, the non-skin side of the back sheet is provided with a main adhesive portion to which adhesive is applied, and in the unfolded state, the low basis weight portion has a portion that overlaps with the main adhesive portion when viewed in the thickness direction.
[0026] According to embodiment 9, by having an adhesive portion of the main body that overlaps with the low-basis-weight portion when viewed in the thickness direction, the position of the low-basis-weight portion is less likely to shift relative to the packaging material even when packaged. This reduces deformation of the low-basis-weight portion and reduces the risk of the backsheets of absorbent articles sticking together due to the low-basis-weight portions being spaced apart from each other in the longitudinal direction.
[0027] Embodiment 10 is an absorbent article packaging according to any one of Embodiments 1 to 9, wherein in the unfolded state, the absorbent article has a pair of wing portions extending outward on both sides in the width direction, and each of the pair of wing portions has a wing adhesive portion on the non-skin side in the thickness direction to which adhesive is applied, and in the packaged state, each of the pair of wing portions is folded inward in the width direction toward the skin side, and when viewed in the thickness direction, each of the low basis weight portions has a portion that overlaps with the wing adhesive portion.
[0028] According to embodiment 10, in the packaged state, the rigidity of the folded wing portion can reduce the risk of the low-basis-weight portion being crushed.
[0029] Embodiment 11 is an absorbent article packaging according to any one of Embodiments 1 to 10, wherein in the unfolded state, the absorbent article has a back sheet located on the non-skin side of the non-skin side sheet portion and a pair of wing portions extending outward on both sides in the width direction, the non-skin side of the back sheet is provided with a main body adhesive portion to which adhesive has been applied, the non-skin side of the pair of wing portions in the thickness direction is provided with wing adhesive portions to which adhesive has been applied, and in the region overlapping with the wing adhesive portion in the longitudinal direction, the other end in the width direction of the low basis weight portion on one side in the width direction is located to one side in the width direction from the center in the width direction of the absorbent article, and the other end in the width direction of the low basis weight portion on the other side in the width direction is located to the other side in the width direction from the center in the width direction of the absorbent article.
[0030] According to embodiment 11, in the region overlapping with the wing adhesive portion in the longitudinal direction, the risk of the non-skin sides of the pair of low-basis-weight portions adhering to each other at the main body adhesive portion can be reduced, making it easier to maintain the shape of the absorbent article in the area corresponding to the wearer's crotch when worn. Furthermore, since the low-basis-weight portion overlapping with the wing adhesive portion in the longitudinal direction is likely to come into contact with the wearer's excretory opening when the absorbent article is worn, the fact that the low-basis-weight portions provided on both sides in the width direction, which have relatively low rigidity, are not continuous reduces the risk that the low-basis-weight portions will hinder the diffusion of excrement in the longitudinal direction, thus making it easier to promote the absorption of excrement over a wide area of the absorbent article.
[0031] Embodiment 12 is an absorbent article packaging according to any one of Embodiments 1 to 11, wherein the packaging material comprises an outer material and a release sheet provided inside the outer material, the outer material and the release sheet are fixed together by a fixing portion to which adhesive is applied, and in the unfolded state and in the width direction, at least a part of the fixing portion is provided between a pair of low basis weight areas.
[0032] According to embodiment 12, the rigidity of the fixing part that secures the outer packaging material and the release sheet reduces deformation of the central part in the width direction of the absorbent article in the packaged state, making it easier to maintain the shape of the area that is likely to come into contact with the excretory opening when worn.
[0033] Embodiment 13 is an absorbent article packaging according to Embodiment 12, wherein a high-density portion is provided between the low-basis-weight portion on one side and the low-basis-weight portion on the other side in the width direction, where the density of the liquid absorbent fibers is higher than that of the surrounding area.
[0034] According to embodiment 13, the rigidity of the high-density portion reduces deformation of the central part in the width direction of the absorbent article in the packaged state, making it easier to maintain the shape of the area that is likely to come into contact with the wearer's excretory opening when worn.
[0035] Embodiment 14 is an absorbent article packaging according to any one of Embodiments 1 to 13, having, in the packaged state, a portion where the low basis weight portions on one side overlap when viewed in the thickness direction, and a portion where the low basis weight portions on the other side overlap when viewed in the thickness direction.
[0036] According to embodiment 14, in the packaged state, the low-basis-weight portion on one side and the low-basis-weight portion on the other side become more resistant to external forces, thereby reducing the risk of deformation of the area between the low-basis-weight portion on one side and the low-basis-weight portion on the other side.
[0037] Embodiment 15 is an absorbent article packaging according to any of Embodiments 1 to 14, wherein, in the unfolded state, the absorbent article has a pair of wing portions extending outward on both sides in the width direction, and each of the pair of wing portions has a wing adhesive portion on the non-skin side in the thickness direction to which adhesive is applied, and each of the low-basis-weight portion on one side and the low-basis-weight portion on the other side has a central low-basis-weight portion that overlaps with the wing adhesive portion in the longitudinal direction, and the central low-basis-weight portion does not overlap with the folded portion when viewed in the thickness direction.
[0038] According to embodiment 15, the central low-basis-weight portion that overlaps with the wing adhesive portion in the longitudinal direction is likely to come into contact with the excretory opening when worn. Therefore, by ensuring that the central low-basis-weight portion and the folding portion do not overlap in the longitudinal direction, the risk of the central low-basis-weight portion being crushed when the absorbent article packaging is folded at the folding portion can be reduced.
[0039] Embodiment 16 is an absorbent article packaging according to any one of Embodiments 1 to 15, wherein, in the unfolded state and at a predetermined position in the longitudinal direction, the length in the width direction of the low basis weight portion on one side is longer than the length in the width direction of the compressed portion located on one side in the width direction.
[0040] According to embodiment 16, the risk of the low-basis-weight section on one side being crushed can be reduced.
[0041] ===Execution=== Hereinafter, embodiments of the absorbent article packaging according to the present invention will be described using sanitary napkin 1 (hereinafter also referred to as "napkin 1") as an example of the absorbent article. However, the absorbent article is not limited to sanitary napkins, and may also be disposable diapers, panty liners, incontinence pads, fecal incontinence pads, breast pads, and other absorbent articles.
[0042] <<Basic configuration of packaging 100>> Figure 1 is a plan view of the unfolded packaging (also called "packaging for napkin 1" or "absorbent article packaging") 100 as seen from the skin side. Figure 2 is a plan view of the unfolded packaging 100 as seen from the non-skin side. Figure 3 is a plan view of the packaged packaging 100 as seen from the tape member 102 side. The unfolded packaging 100 and the packaged packaging 100 each have a longitudinal direction, a width direction, and a thickness direction that are orthogonal to each other, and the longitudinal direction, width direction, and thickness direction of the packaged packaging 100 are directions that are aligned with the longitudinal direction, width direction, and thickness direction of the unfolded napkin 1, respectively. Center CC shown in Figure 1 etc. indicates the center of napkin 1 in the width direction, and center CL indicates the center of napkin 1 in the longitudinal direction.
[0043] The packaging 100 comprises a napkin 1 and packaging material 101 for packaging the napkin 1. As shown in Figure 1, a tape member 102 is provided at the end of the packaging material 101 that is located on the front side of the napkin 1 when unfolded. When opening the packaging 100 in its unfolded state, the wearer first grasps the tape member 102 and pulls the tape member 102 to unfold the packaging 100. The tape member 102 is not necessarily required, but it is preferable to provide it.
[0044] The packaging 100 has a first folding section F1 and a second folding section F2. To unfold the packaging from the state shown in Figure 3, the first folding section F1 is unfolded first, and then the second folding section F2 is unfolded. The first folding section F1 and the second folding section F2 are both aligned in the width direction. Note that the first folding section F1 and the second folding section F2 are not "lines" but "regions" with a certain area.
[0045] The "unfolded" packaging 100 refers to the state in which the packaging 100 in its unfolded state is opened and the unfoldable parts of the folded portions of the packaging material 101 and napkin 1 are unfolded, as shown in Figures 1 and 2. The "packaged" packaging 100 refers to the state in which a predetermined part of the unfolded packaging 100 is sealed by folding a pair of wing portions 1W inward in the width direction, folding the top sheet 21 inward at the first folded portion F1 and the second folded portion F2, and welding and joining the ends of the packaging material 101 in the width direction to form a welded portion 105 (Figure 3).
[0046] Figure 4 is a schematic cross-sectional view taken along the line A-A in Figure 1. Figure 5 is a diagram illustrating the structure of the packaging 100. Figure 4 schematically shows a cross-sectional view of the napkin 1, and the dimensions are not necessarily accurate. Figure 5 is a perspective view of the unfolded packaging 100, disassembled into the napkin 1, release sheet 103, and packaging material 101. As shown in Figures 2, 4, and 5, the unfolded packaging 100 consists of the napkin 1, release sheet 103, and packaging material 101 stacked in order from the skin side in the thickness direction. The napkin 1 and release sheet 103 are fixed together so as to be removable by the adhesive part 32 (described later) of the napkin 1, and the release sheet 103 and packaging material 101 are fixed together so as not to be removable by the fixing part 104.
[0047] The packaging material 101 is a sheet-like packaging component that individually wraps the napkins 1, and is removed when the napkins 1 are used. The packaging material 101 has a tape component 102 and a release sheet 103. As the packaging material 101, various films such as plastic film and nylon film, nonwoven fabric, and films laminated with nonwoven fabric can be used as outer packaging materials.
[0048] The release sheet 103 is a rectangular sheet material. The release sheet 103 is provided to prevent deterioration of the adhesive part 32 of the napkin 1, and the side of the release sheet 103 facing the napkin 1 is a resin film layer that allows the napkin 1 to be easily peeled off. Note that the packaging body 100 does not necessarily need to have a release sheet 103, and if the packaging body 100 does not have a release sheet 103, the side of the packaging material 101 facing the napkin 1 can be made of a material that allows the napkin 1 to be easily peeled off.
[0049] <<<Configuration of napkin 1 in this embodiment>>> When unfolded, napkin 1 has a longitudinal direction, a width direction, and a thickness direction. In the longitudinal direction, the side that comes into contact with the wearer's lower abdomen is the front side, and the side that comes into contact with the wearer's buttocks is the back side. In the thickness direction, the side that comes into contact with the wearer's skin is the skin side, and the opposite side is the non-skin side.
[0050] The napkin 1 has an absorbent core 10, a top sheet 21, a pair of side sheets 23, and a back sheet 31. A sheet-like second sheet 22 may be located on the skin side of the absorbent core 10 and on the non-skin side of the top sheet. Each material adjacent to each other in the thickness direction is joined together with an adhesive such as hot melt.
[0051] The napkin 1 has a pair of wing portions 1W extending outwards in both directions in the width direction from the center in the longitudinal direction. The wing portions 1W are mainly formed by a side sheet 23 and a back sheet 31.
[0052] The top sheet 21 is a liquid-permeable sheet located on the skin side of the absorbent 10. The top sheet 21 is a surface sheet located on the skin side of the skin-side sheet portion 12a (core wrap sheet 12) described later. Examples of the top sheet 21 include nonwoven fabrics made of synthetic fibers such as polyethylene (PE) and polypropylene (PP) (e.g., air-through nonwoven fabrics and spunbond nonwoven fabrics), flexible sheets such as synthetic resin films with perforations, and nonwoven fabric sheets made of cotton. In this embodiment, the top sheet 21 is formed of a liquid-permeable sheet of air-through nonwoven fabric made of polyethylene terephthalate (PET) and polyethylene (PE), etc.
[0053] The pair of side sheets 23 are located on the non-skin side of the top sheet 21 and second sheet 22, and on the skin side of the absorbent 10, and are sheets that extend outward from both sides in the width direction of the top sheet 21, etc. Examples of side sheets 23 include the same flexible liquid-permeable nonwoven fabric as the top sheet 21, or a hydrophobic nonwoven fabric. Furthermore, a reinforcing sheet 24 is provided between the side sheets 23 and the back sheet 31 in the thickness direction, outside the width direction of the top sheet 21, second sheet 22, and absorbent 10, to reinforce the strength of the side sheets 23. For example, the same sheet material as the back sheet 31, etc., can be used as the reinforcing sheet 24.
[0054] The backsheet 31 is a sheet located on the non-skin side of the absorbent core 10. Examples of the backsheet 31 include liquid-impermeable sheets such as polyethylene (PE) resin film. The shape of the backsheet 31 is almost identical to the outer shape of the napkin 1.
[0055] The backsheet 31 is provided with multiple adhesive body sections 32 on the non-skin side. In this embodiment, the adhesive body section 32 is an area to which multiple strip-shaped hot-melt adhesives are applied along the longitudinal direction. When wearing the napkin 1, the adhesive body section 32 can be attached to the inside of the crotch area of the underwear (clothing) to prevent the napkin 1 from shifting relative to the wearer's body.
[0056] Furthermore, the wing portion 1W is provided with a wing adhesive portion 33 on the non-skin side of the backsheet 31. In this embodiment, the wing adhesive portion 33 is an area to which a rectangular hot-melt adhesive has been applied. When wearing the napkin 1, the wing portion 1W is folded back to the non-skin side of the underwear, and the wing adhesive portion 33 is attached to the non-skin side in the crotch area of the underwear, thereby securing the napkin 1 to the underwear.
[0057] The position in the longitudinal direction that overlaps with the wing adhesive portion 33 (see Figure 1) is the crotch region CA. The crotch region CA is the area that comes into contact with the wearer's crotch in the longitudinal direction when worn, and is the area that comes into contact with the blood discharge opening from which the wearer's excrement is discharged. If the napkin 1 does not have a wing portion 1W, the crotch region CA in the worn state can be the area in the longitudinal direction that overlaps with the area with the highest basis weight of the absorbent core 11 (described later) (the mid-high portion 11d described later).
[0058] The absorbent body 10 has an absorbent core 11 and a core wrap sheet 12. Examples of the absorbent core 11 include liquid absorbent fibers such as pulp fibers, cellulose-based absorbent fibers, polyolefins, polyesters, acrylics, acrylates, etc., which are molded into a predetermined shape and to which a superabsorbent polymer (SAP) is added. Figure 6A is a plan view of the absorbent core 11. Figure 6B is a schematic cross-sectional view taken along the line J-J in Figure 6A. Figure 7 is a schematic cross-sectional view taken along the line K-K in Figure 6A. Note that in Figures 6A, 6B and 7, irregularities caused by compression sections such as the compression section EL are omitted.
[0059] The absorbent core 11 has regions with different basis weights of liquid absorbent fibers. The absorbent core 11 has a pair of openings 11h. The openings 11h are portions through which the absorbent core 11 penetrates in the thickness direction, and are portions where the basis weight of the liquid absorbent fibers is zero (0). The absorbent core 11 has adjacent portions 11n that are adjacent to the contour of the openings 11h from the outside. It also has a high-basis-weight portion 11f that is adjacent to the adjacent portions 11n from the outside and has a higher basis weight of liquid absorbent fibers than the adjacent portions 11n. In other words, the adjacent portions 11n have a lower basis weight of liquid absorbent fibers than the high-basis-weight portion 11f. The high-basis-weight portion 11f has a medium-high portion 11d that is thicker (longer in the thickness direction) than the surrounding area, located at a position that overlaps with the wing adhesive portion 33 in the longitudinal direction and between it and the pair of openings 11h in the width direction. In the high-basis-weight portion 11f, the medium-high portion 11d is a portion where the basis weight of the liquid absorbent fibers is even higher than the surrounding area. In this embodiment, the raised portion 11d is a part that protrudes towards the non-skin side in the thickness direction and is a substantially elliptical region in plan view. By positioning the raised portion 11d in the center of the absorbent core 11 in the width direction and overlapping with the crotch region CA in plan view, it becomes easier to retain excrement discharged from the wearer's anus within the absorbent core 11 when worn. Alternatively, the raised portion 11d of the absorbent core 11 may protrude towards the skin side in the thickness direction. By protruding the raised portion 11d towards the skin side, it becomes easier to bring the napkin 1 into contact with the wearer's anus when worn, making it easier to fit the napkin 1 to the wearer's body and to quickly absorb excrement.
[0060] The pair of openings 11h are spaced apart in the width direction and have a shape that aligns with the longitudinal direction. In this embodiment, each pair of openings 11h is provided in multiple locations along the longitudinal direction, and is provided on both outer sides of the three equal divisions of the width direction of the absorbent core 11. In the absorbent core 11, the opening 11h located on one side in the width direction (one side from the center CC in the width direction) is the one-side opening 11hx, and the opening 11h located on the other side in the width direction (one side from the center CC in the width direction) is the other-side opening 11hy. Since the liquid absorbent fibers and superabsorbent polymer (SAP) constituting the absorbent core 11 are soft or fluid materials, the openings 11h are not only areas through which the absorbent core 11 is completely penetrated and where no liquid absorbent fibers are provided at all, but the openings 11h may also contain some liquid absorbent fibers or superabsorbent polymer (SAP), etc.
[0061] In this embodiment, the pair of openings 11h are provided as a first opening 11ha, a second opening 11hb, and a third opening 11hc, respectively, in order from the front in the longitudinal direction. Specifically, the pair of first openings 11ha are provided in front of the wing adhesive portion 33 in the longitudinal direction, the pair of second openings 11hb are provided in a position where at least a part of them overlaps with the wing adhesive portion 33 in the longitudinal direction, and the pair of third openings 11hc are provided behind the wing adhesive portion 33 in the longitudinal direction. The first opening 11ha, the second opening 11hb, and the third opening 11hc are each openings along the longitudinal direction, with a length in the longitudinal direction being longer than the length in the width direction. The first opening 11ha has a first opening 11hxa located on one side in the width direction and a first opening 11hya located on the other side. The second opening 11hb has a first-side second opening 11hxb located on one side in the width direction and a second-side second opening 11hyb located on the other side. The third opening 11hc has a first-side third opening 11hxc located on one side in the width direction and a third-side third opening 11hyc located on the other side.
[0062] An adjacent portion 11n is provided on the outside of each opening 11h. Specifically, the first opening 11ha, the second opening 11hb, and the third opening 11hc are each provided with a first adjacent portion 11na, a second adjacent portion 11nb, and a third adjacent portion 11nc that are adjacent to the contours of each opening 11ha, 11hb, and 11hc from the outside. The first adjacent portion 11na, the second adjacent portion 11nb, and the third adjacent portion 11nc are provided so as to surround the entire contour of the first opening 11ha, the second opening 11hb, and the third opening 11hc, respectively. Since the first opening 11ha, the second opening 11hb, and the third opening 11hc are shaped along the longitudinal direction, the first adjacent parts 11na, the second adjacent part 11nb, and the third adjacent part 11nc, which are adjacent to the first opening 11ha, the second opening 11hb, and the third opening 11hc from the outside, are also shaped along the longitudinal direction. The first adjacent part 11na has a first adjacent part 11nxa located on one side in the width direction and a first adjacent part 11nya located on the other side. The second adjacent part 11nb has a second adjacent part 11nxb located on one side in the width direction and a second adjacent part 11nyb located on the other side. The third adjacent part 11nc has a third adjacent part 11nxc located on one side in the width direction and a third adjacent part 11nyc located on the other side.
[0063] In this embodiment, the absorbent core 11 is provided with a pair of low-basis-weight sections 11g, which are arranged in order from the front in the longitudinal direction: a first low-basis-weight section 11ga, a second low-basis-weight section 11gb, and a third low-basis-weight section 11gc. The pair of low-basis-weight sections 11g are portions in which the basis weight of the liquid absorbent fibers is lower than that of the surrounding area. Specifically, the first low-basis-weight section 11ga is composed of a first low-basis-weight section 11gxa on one side, consisting of a first opening 11hxa on one side and a first adjacent section nxa on one side, and a first low-basis-weight section 11gya on the other side, consisting of a first opening 11hya on the other side and a first adjacent section nya on the other side. The second low-basis-weight section 11gb is composed of a one-side second low-basis-weight section 11gxb consisting of a one-side second opening 11hxb and a one-side second adjacent section 11nxb, and a other-side second low-basis-weight section 11gyb consisting of a other-side second opening 11hyb and a other-side second adjacent section 11nyb. The third low-basis-weight section 11gc is composed of a one-side third low-basis-weight section 11gxc consisting of a one-side third opening 11hxc and a one-side third adjacent section 11nxc, and a other-side third low-basis-weight section 11gyc consisting of a other-side third opening 11hyc and a other-side third adjacent section 11nyc.
[0064] The core wrap sheet 12 is a liquid-permeable sheet member that improves the shape retention of the absorbent core 11, and can be exemplified by tissue paper. In this embodiment, the skin side and non-skin side of the absorbent core 11 are covered with the core wrap sheet 12 by folding both ends of the core wrap sheet 12 back to the non-skin side of the absorbent core 11, but it is not limited to this. For example, the core wrap sheet 12 may be configured as two sheet members, one placed on the skin side and the other on the non-skin side of the absorbent core 11.
[0065] As shown in Figure 8, the core wrap sheet 12 has a skin-side sheet portion 12a located on the skin side of the absorbent core 11, and a non-skin-side sheet portion 12b located on the non-skin side of the absorbent core 11. Figure 8 is an enlarged view of the absorbent body 10 in Figure 4.
[0066] The core wrap sheet 12 is fixed to the absorbent core 11 by applying an adhesive such as a hot melt adhesive to the non-skin side of the skin-side sheet portion 12a in a predetermined application pattern, and by applying an adhesive to the skin side of the non-skin-side sheet portion 12b in a predetermined application pattern. The applied adhesive joins the skin-side sheet portion 12a and the non-skin-side sheet portion 12b at positions that overlap with each opening 11h when viewed in the thickness direction, forming a joint portion 12s. The adhesive application pattern in region S can be a spiral pattern, an omega (Ω) pattern, a wave pattern, a linear (stripe) pattern, etc.
[0067] As shown in Figure 1, the napkin 1 has linear compression sections EL. The linear compression sections EL are the parts of the napkin 1 that have been compressed in the thickness direction. By providing the linear compression sections EL, the bonding of each component in the thickness direction is strengthened, the density of the fibers is increased, and the liquid absorbency can be improved. The linear compression sections EL are linear compression sections that run along the longitudinal direction in a plan view, and a pair is provided with a predetermined interval in the width direction. In the thickness direction, the linear compression sections (compression sections) EL at positions that overlap with the low basis weight section 11g compress at least the skin-side sheet section 12a and the non-skin-side sheet section 12b in the thickness direction. Within the low basis weight section 11g, the linear compression sections EL at positions that overlap with each opening 11h strengthen the bonding by pressing the joint 12s, which joins the skin-side sheet section 12a and the non-skin-side sheet section 12b, in the thickness direction. The linear compression section EL comprises a one-side compression section ELx provided on one side in the width direction and a other-side compression section ELy provided on the other side in the width direction.
[0068] In this embodiment, the one-sided compression portion ELx of the napkin 1 directly joins the skin-side sheet portion 12a and the non-skin-side sheet portion 12b at a position where it overlaps with the one-sided low-basis-weight portion 11gx when viewed in the thickness direction of the napkin 1 (for example, position AA in the longitudinal direction). Similarly, the other-sided compression portion ELx directly joins the skin-side sheet portion 12a and the non-skin-side sheet portion 12b at a position where it overlaps with the other-sided low-basis-weight portion 11gy when viewed in the thickness direction of the napkin 1 (for example, position AA in the longitudinal direction). However, the one-sided compression portion ELx and the other-sided compression portion ELx may indirectly join the skin-side sheet portion 12a and the non-skin-side sheet portion 12b by interposing liquid-absorbing fibers or superabsorbent polymer (SAP) of the absorbent core 11 between them.
[0069] Furthermore, the napkin 1 has front compression sections Ef1 and Ff2 located in front of the pair of linear compression sections EL, and a rear compression section Eu located behind the pair of linear compression sections EL. The front compression sections Ef1 and Ff2 and the rear compression sections Eu1 and Eu2 are portions that compress at least the skin-side sheet portion 12a and the non-skin-side sheet portion 12b in the thickness direction, and in the napkin 1, these are portions that compress the top sheet 21, the second sheet 22 and the absorbent material 10 in the thickness direction. The front compression sections Ef1 and Ff2 are each provided at the front end of the absorbent core 11 so as to straddle the center CC in the width direction from one side to the other in the width direction, and in a shape that follows the contour of the front end of the absorbent core 11. The rear compression sections Eu1 and Eu2 are provided at the rear end of the absorbent core 11, on one side in the width direction and the other side, respectively, in a shape that follows the contour of the rear end of the absorbent core 11.
[0070] Multiple circular compression sections ee are provided in the central part in the width direction and in a position that overlaps with the crotch area CA in the longitudinal direction. The circular compression sections ee are circular compression sections in a plan view, and are portions of the top sheet 21, second sheet 22, and absorbent 10 that have been compressed in the thickness direction.
[0071] The linear compression section EL and the circular compression section ee are the parts where members stacked in the thickness direction are crushed, so the fiber density of each member in each compression section is higher than the fiber density of the parts where no compression section is provided. The linear compression section EL and the circular compression section ee are formed, for example, by passing the napkin 1 in the manufacturing process through the gap between a convex roller having multiple protrusions and an anvil roller with a flat surface and compressing it.
[0072] <<<Regarding Packaging 100>>> It has long been known that the more flexible an absorbent material is, the more easily it conforms to the wearer's body and fits well when worn. However, the more flexible an absorbent material is, the greater the risk that it may deform due to external forces while in its packaging.
[0073] In contrast, the napkin 1 of the packaging 100 has a low basis weight section 11g in the absorbent core 11, where the basis weight of the liquid absorbent fibers is lower than that of the surrounding area, thereby improving the flexibility of the napkin 1. As shown in Figure 1, etc., when the packaging 100 is unfolded, this low basis weight section 11g is provided on one side in the width direction as one low basis weight section 11gx and on the other side as the other low basis weight section 11gy, and these are arranged along the longitudinal direction and intermittently in the longitudinal direction. The front end of the lowest low basis weight section 11g located at the front is inclined with respect to the longitudinal direction, and the rear end of the lowest low basis weight section 11g located at the rear is also inclined with respect to the longitudinal direction. Specifically, in the napkin 1, the first low basis weight section 11ga, the second low basis weight section 11gb, and the third low basis weight section 11gc are provided spaced apart in the longitudinal direction. Furthermore, the low-basis-weight section 11gx on one side and the low-basis-weight section 11gy on the other side have their front ends xap and yap inclined with respect to the longitudinal direction, respectively, at the front end xap of the first low-basis-weight section 11gxa on one side and the front end yap of the first low-basis-weight section 11gyb on the other side, which are located at the very front, and the rear end xcp of the third low-basis-weight section 11gxc on one side and the rear end ycp of the third low-basis-weight section 11gyc on the other side, which are located at the very back, which are inclined with respect to the longitudinal direction. At least the skin-side sheet section 12a and the non-skin-side sheet section 12b are compressed in the thickness direction, and each has a pair of linear compression sections EL along the longitudinal direction, and when the napkin 1 is viewed in the thickness direction, the linear compression sections EL have a portion that overlaps with the low-basis-weight section 11g.
[0074] The linear compression section EL is the part of the napkin 1 where at least the skin-side sheet portion 12a and the non-skin-side sheet portion 12b are compressed in the thickness direction. Therefore, the part where the linear compression section EL is provided is a part where the overlapping members are directly or indirectly crushed and joined by the compression, and thus has higher rigidity than other parts.
[0075] Therefore, by providing the napkin 1 with a linear compression section EL, deformation of the napkin 1 in the packaging body 100 in the packaged state can be reduced, but there is a risk that the napkin 1 itself will become hard. In this respect, the napkin 1 of this embodiment has a linear compression section EL at a position that overlaps with the low basis weight section 11g when viewed in the thickness direction, which makes it easier for the low basis weight section 11g to form the absorbent core 11, thus improving the flexibility of the napkin 1. On the other hand, the more flexible the napkin 1 becomes, the more easily the napkin 1 will deform when external force is applied to the packaging body 100 in the packaged state, and there is a risk that the low basis weight section 11g, which has low rigidity, will be crushed. In this regard, the front end xap of the first low-basis-weight section 11gxa on one side and the front end yap of the first low-basis-weight section 11gyb on the other side are inclined with respect to the longitudinal direction, and the rear end xcp of the third low-basis-weight section 11gxc on one side and the rear end ycp of the third low-basis-weight section 11gyc on the other side are inclined with respect to the longitudinal direction, thereby reducing the risk that the first low-basis-weight section 11gxa on one side and the first low-basis-weight section 11gyb on the other side, the third low-basis-weight section 11gxc on one side and the third low-basis-weight section 11gyc on the other side will be crushed by force from the outside of the packaging body 100.
[0076] Furthermore, when viewing napkin 1 in the thickness direction, the linear compression section EL, which is positioned to overlap with the low basis weight section 11g, can reduce the risk of the low basis weight section 11g being crushed.
[0077] Furthermore, because the low-basis-weight sections 11g are intermittently arranged in the longitudinal direction, there are high-basis-weight sections 11f between adjacent low-basis-weight sections 11g in the longitudinal direction, where the basis weight of the liquid-absorbing fibers is higher than that of the low-basis-weight sections 11g. Therefore, even if the low-basis-weight sections 11g are crushed by force applied from the outside in the width direction while the packaging 100 is in its packaged state, the high-basis-weight sections 11f make it easier to return the deformation of the low-basis-weight sections 11g to their original shape. As a result, even if force is repeatedly applied from the outside in the width direction of the packaging 100 while the packaging 100 is in its packaged state, the risk of the low-basis-weight sections 11g being completely crushed is reduced, making it easier to wear the napkin 1 with the low-basis-weight sections 11g intact.
[0078] In this way, the napkin 1 in the packaging 100 improves flexibility while also reducing deformation of the low-basis-weight portion 11g even in the packaging state, thereby improving the comfort of the napkin 1 when worn.
[0079] Regarding the absorbent core 11, it is preferable that, as in the napkin 1 of this embodiment, the low basis weight portion 11g has a portion (opening 11h) where the basis weight of the liquid absorbent fibers is zero. Having a portion of liquid absorbent fibers with zero basis weight in the absorbent core 11 further improves the flexibility of the napkin 1 (absorbent core 11). Furthermore, since the skin-side sheet portion 12a and the non-skin-side sheet portion 12b can be brought into contact with each other in the portion of liquid absorbent fibers with zero basis weight inside the low basis weight portion 11g, the bond between the skin-side sheet portion 12a and the non-skin-side sheet portion 12b can be made stronger, thereby reducing the risk of the low basis weight portion 11g being crushed by force applied from outside the packaging 100 in the packaged state. In addition, in the worn state, the bonded skin-side sheet portion 12a and the non-skin-side sheet portion 12b reduce the risk of the absorbent core 11 losing its shape, and reduce the bunching of the napkin 1. Furthermore, when the absorbent core 11 absorbs excrement, there is a risk that the absorbent core 11 may deform and separate from the skin-side sheet portion 12a and the non-skin-side sheet portion 12b. However, the joint portion 12s, where the skin-side sheet portion 12a and the non-skin-side sheet portion 12b are joined, makes it easier for the absorbent core 11 to deform integrally with the skin-side sheet portion 12a and the non-skin-side sheet portion 12b, thereby reducing discomfort to the wearer.
[0080] The joint portion 12s of the napkin 1 may be joined only by an adhesive such as a hot melt adhesive applied to at least one of the non-skin side of the skin-side sheet portion 12a or the skin side of the non-skin-side sheet portion 12b, or it may be joined by compressing the skin-side sheet portion 12a and the non-skin-side sheet portion 12b together by compression in the thickness direction by a linear compression portion EL, or it may be joined by both adhesive and compression.
[0081] Furthermore, as shown in Figure 6A, it is preferable that the front end xaf of the first low-basis-weight section 11gxa on one side and the front end yaf of the first low-basis-weight section 11gyb on the other side, which are located at the very front, are spaced apart from the front edge of the absorbent core 11, and the rear end xcu of the third low-basis-weight section 11gxc on one side and the rear end ycu of the third low-basis-weight section 11gyc on the other side, which are located at the very rear, are spaced apart from the front edge of the absorbent core 11.
[0082] This reduces the risk of the absorbent core 11 becoming excessively flexible, and reduces the risk of the absorbent core 11 deforming against the wearer's intentions while in the packaged state. Furthermore, since high-basis-weight sections 11f, which have a higher basis weight of liquid absorbent fibers than the low-basis-weight section 11g, are provided in front of the first low-basis-weight section ga, which is located at the very front, and behind the third low-basis-weight section gc, which is located at the very back, even if the absorbent core 11 (napkin 1) deforms when force is applied from the outside in the longitudinal direction of the packaged body 100 and when the napkin 1 is worn, the high-basis-weight sections 11f make it easier to return the absorbent core 11 to its original shape. Therefore, by reducing the risk of the low-basis-weight section 11g of the absorbent core 11 remaining crushed while worn, it becomes easier to improve the comfort of the napkin 1 when worn.
[0083] As described above, the napkin 1 has a pair of wing portions 1W, and wing adhesive portions 33 are provided on the non-skin sides of the pair of wings 1W. In such a napkin 1, as shown in Figure 1, when unfolded, one low-basis-weight portion 11gx and the other low-basis-weight portion 11gy each have a second low-basis-weight portion (central low-basis-weight portion) 11gb (11gxb, 11gyb) that overlaps with the wing adhesive portion 33 in the longitudinal direction. Both ends of the second low-basis-weight portion 11gb in the longitudinal direction are inclined inward with respect to the longitudinal direction. Specifically, the front end xbq and rear end xbr of the second low-basis-weight portion 11gxb on one side are inclined inward with respect to the longitudinal direction, and the front end xbq and rear end ybr of the second low-basis-weight portion 11gyb on the other side are inclined inward with respect to the longitudinal direction. In other words, the second low-basis-weight portion 11gxb on one side of napkin 1 has a curved shape in which the central part in the longitudinal direction protrudes outward in the width direction (to one side) compared to the ends xbq and xbr in the longitudinal direction, and the second low-basis-weight portion 11gyb on the other side has a curved shape in which the central part in the longitudinal direction protrudes outward in the width direction (to the other side) compared to the ends ybq and ybr in the longitudinal direction.
[0084] In the napkin 1, the portion that overlaps with the wing adhesive portion 33 in the longitudinal direction is the part that is likely to come into contact with the wearer's anus when worn. Therefore, because both ends of the second low-basis-weight portion 11gb in the longitudinal direction are inclined inward with respect to the longitudinal direction, when force is applied from the outside in the width direction in the packaged and worn state, the force is more easily buffered between the ends of the second low-basis-weight portion 11gb in the longitudinal direction than between the ends xbq, xbr, ybq, and ybr of the second low-basis-weight portion 11gb in the longitudinal direction, making it easier to maintain the shape of the portion of the napkin 1 that comes into contact with the wearer's anus, and between one second low-basis-weight portion 11gxb and the other second low-basis-weight portion 11gyb. In addition, the risk of the ends of the second low-basis-weight portion 11gxb and the other second low-basis-weight portion 11gyb being crushed in the longitudinal direction is reduced.
[0085] Furthermore, as shown in Figure 1, when the unfolded packaging 100 has a second low-basis-weight portion (central low-basis-weight portion) 11gb (11gxb, 11gyb) in the longitudinal direction, where one low-basis-weight portion 11gx and the other low-basis-weight portion 11gyb each have a portion that overlaps with the wing adhesive portion 33, it is preferable that, when viewing the unfolded packaging 100 in the thickness direction, the second low-basis-weight portion 11gb (11gxb, 11gyb) does not overlap with the folded portions F1 and F2.
[0086] In the napkin 1, the area where the wing adhesive portion 33 overlaps with the napkin in the longitudinal direction (crotch area CA) is a part that is likely to come into contact with the wearer's excretory opening when worn. Therefore, when viewing the napkin 1 in the thickness direction, by ensuring that the second low-basis-weight portion 11gb does not overlap with the folding portions F1 and F2, the risk of deformation or crushing of the second low-basis-weight portion 11gb, which would occur when the napkin is folded at the folding portions F1 and F2, can be reduced.
[0087] In the unfolded state of the packaging 100, it is preferable that at least one folded portion does not overlap with the linear compression portion EL when viewed in the thickness direction. In the napkin 1 of this embodiment, as shown in Figure 1, when the unfolded packaging 100 is viewed in the thickness direction, the second folded portion F2 does not overlap with the linear compression portion EL. On the other hand, when the unfolded packaging 100 is viewed in the thickness direction, the first folded portion F1 overlaps with the linear compression portion EL. The napkin 1 has two folded portions F1 and F2, and the second folded portion F2 is a folded portion provided on the rear side and is the first part to be folded when the unfolded packaging 100 is returned to its packaged state.
[0088] Thus, when viewing the unfolded packaging 100 in the thickness direction, the second folding portion F2, which does not overlap with the linear compression portion EL, can have lower rigidity than the first folding portion F1, which overlaps with the linear compression portion EL. This makes it easier to fold the packaging 100 at the second folding portion F2 and easier to maintain the folded shape of the packaging 100 in the packaged state.
[0089] In this embodiment, when the unfolded packaging 100 is viewed in the thickness direction, the second folded portion F2 does not overlap with the linear compression portion EL, while the first folded portion F1 overlaps with the linear compression portion EL. However, the embodiment is not limited to this configuration. For example, when the unfolded packaging 100 is viewed in the thickness direction, all folded portions (the first folded portion F1 and the second folded portion F2) may not overlap with the linear compression portion EL.
[0090] In the case of napkin 1 of this embodiment, which has a raised center portion 11d that is thicker than the surrounding area and a wing portion 1W having a wing adhesive portion 33 on the non-skin side, it is preferable that in the unfolded packaging 100, at least a part of the raised center portion 11d is located at a position that overlaps with the wing adhesive portion 33 in the longitudinal direction (crotch area CA) and is located between a pair of low basis weight portions 11g in the width direction. In napkin 1, the raised center portion 11d of the absorbent core 11, which is thicker and has a high basis weight of liquid absorbent fibers, is also the raised center portion 11d that is thicker than the surrounding area of the napkin 1.
[0091] Of the napkin 1, the portion that overlaps with the wing adhesive portion 33 in the longitudinal direction is the portion that is most likely to come into contact with the wearer's anus when worn. By providing at least a portion of the mid-high portion 11d at a position that overlaps with the wing adhesive portion 33 in the longitudinal direction, and between a pair of low-basis-weight portions 11g in the width direction, the mid-high portion 11d is positioned to easily come into contact with the wearer's anus in the longitudinal direction, while providing low-basis-weight portions 11g on both sides of the mid-high portion 11d in the width direction. As a result, when force is applied to the packaging 100 from the outside in the width direction while the packaging 100 is in its packaged state, the force acts on the low-basis-weight portions 11g provided on both sides of the mid-high portion 11d in the width direction before the mid-high portion 11d, making it easier for the pair of low-basis-weight portions 11g to buffer the external force. Therefore, it becomes easier to maintain the shape of the mid-high portion 11d, and the napkin 1 becomes more efficient at absorbing waste when worn.
[0092] Furthermore, in the case of napkin 1, where the packaging body 100 has front compression sections Ef1 and Ef2 in front of the linear compression section EL and rear compression sections Eu1 and Eu2 in rear of the linear compression section EL, it is preferable that, in the packaged state of the packaging body 100, when viewed in the thickness direction, the front compression sections Ef1 and Ef2 and the rear compression sections Eu1 and Eu2 each have portions that overlap with the mid-high section 11d. Figure 9 is a schematic diagram showing the cross section in the direction of the arrow M-M in Figure 3. Figure 9 is a schematic diagram showing the positions of the mid-high section 11d, the front compression sections Ef1 and Ef2 and the rear compression sections Eu1 and Eu2 of the packaged packaging body 100, and the MM position in Figure 3 is the same as MM in the unfolded state in Figure 1. In Figure 9, the dimensions etc. are not necessarily accurate. As shown in Figure 9, in the packaged state, the packaging body 100 of this embodiment has front compression sections Ef1 and Ef2 that overlap with the mid-high section 11d when viewed in the thickness direction, and the rear compression section Eu1 that overlaps with the mid-high section 11d.
[0093] As a result, when force is applied to the packaging 100 from the outside in the width direction while the packaging 100 is in its packaged state, the force acts on the low basis weight sections 11g provided on both sides of the width direction of the mid-high section 11d before the mid-high section 11d, making it easier for the pair of low basis weight sections 11g to buffer the external force, and when viewed in the thickness direction, the front compression sections Ef1, Ef2 and the rear compression sections Eu1, Eu2, which are the parts of the napkin 1 that have high rigidity, overlap with the mid-high section 11d, making it easier to maintain the shape of the mid-high section 11d, and making it easier for the napkin 1 to absorb excrement when worn.
[0094] Furthermore, when the packaging 100 is unfolded, it is preferable that, when viewed in the thickness direction, each pair of low-basis-weight portions 11g overlaps with the main adhesive portion 32 provided on the non-skin side of the back sheet 31, which is located on the non-skin side of the non-skin side sheet portion 12b of the napkin 1. In the packaging 100 of this embodiment, as shown in Figure 2, when the packaging 100 is unfolded, when viewed in the thickness direction, each low-basis-weight portion 11g overlaps with the main adhesive portion 32.
[0095] Thus, when viewed in the thickness direction, the pair of low-basis-weight sections 11g have a portion that overlaps with the body-holding adhesive section 32 provided on the non-skin side of the back sheet 31, which is located on the non-skin side of the back sheet 31, which is located on the non-skin side of the non-skin side sheet 12b of the napkin 1. This makes it difficult for the low-basis-weight sections 11g to shift relative to the packaging material 101 and the release sheet 103 when packaged. Therefore, even if external force is applied to the packaging body 100 when packaged, deformation of the low-basis-weight sections 11g can be reduced. Furthermore, since the low-basis-weight sections 11g are provided spaced apart (intermittently) in the longitudinal direction of the napkin 1, the risk of the back sheets 31 of the napkin 1 sticking together at the main body adhesive section 32 can be reduced.
[0096] In this embodiment, when the unfolded packaging 100 is viewed in the thickness direction, the first low-basis-weight portion 11ga, the second low-basis-weight portion 11gb, and the third low-basis-weight portion 11gc each have portions that overlap with the main adhesive portion 32, but this is not limited to this configuration. When the unfolded packaging 100 is viewed in the thickness direction, any one of the first low-basis-weight portion 11ga, the second low-basis-weight portion 11gb, and the third low-basis-weight portion 11gc may have a portion that overlaps with the main adhesive portion 32.
[0097] In this embodiment, the packaging body 100, like the napkin 1, has a pair of wing portions 1W that extend outward on both sides in the width direction when unfolded, and a wing adhesive portion 33 is provided on the non-skin side of the wing portions 1W. In the packaged state, the pair of wing portions 1W are each folded inward in the width direction toward the skin side. At this time, when viewing the packaged body 100 in the thickness direction, it is preferable that the low basis weight portions 11g each have portions that overlap with the wing adhesive portions 33.
[0098] Figure 10 shows the packaged body 100 when unfolded at the folded sections F1 and F2. In Figure 10, the packaged body 100 is unfolded at the folded sections F1 and F2, and the pair of wing sections 1W are each folded inward in the width direction toward the skin side. Therefore, the positional relationship between the wing adhesive section 33 and the second low-basis-weight section 11xb when viewed in the thickness direction as shown in Figure 10 is the same as when it is in the packaged state. In this embodiment, when the packaged body 100 is viewed in the thickness direction, the second low-basis-weight section 11xb has a portion that overlaps with the wing adhesive section 33.
[0099] When the wing 1W, which is provided with the wing adhesive portion 33, is folded back, the portion of the package 100 that overlaps with the wing adhesive portion 33 becomes less susceptible to deformation even when external force is applied, due to the rigidity of the wing portion 1W. Therefore, when viewing the package 100 in the thickness direction, the low basis weight portion 11g has a portion that overlaps with the wing adhesive portion 33, thereby reducing the risk of deformation of the low basis weight portion 11g.
[0100] In the case of the napkin 1 of the packaging 100 of this embodiment, where, in the unfolded state, the napkin has a main adhesive portion 32 on the non-skin side of the back sheet 31, and wing adhesive portions 33 are provided on the non-skin sides of a pair of wing portions 1W extending outward on both sides in the width direction, it is preferable that in the region overlapping with the wing adhesive portion 33 in the longitudinal direction (crotch region CA), the other end of the low basis weight portion 11gx on one side in the width direction is located to one side in the width direction from the center CC of the napkin 1 in the width direction, and the other end of the low basis weight portion 11gy on the other side in the width direction is located to the other side in the width direction from the center CC of the napkin 1 in the width direction. Simply put, as shown in Figure 1, etc., in the crotch area CA in the longitudinal direction, one low basis weight portion 11gx and the other low basis weight portion 11gy are spaced apart with the central CC in between, with one low basis weight portion 11gx located on one side of the central CC in the width direction of the napkin 1, and the other low basis weight portion 11gy located on the other side of the central CC in the width direction of the napkin 1.
[0101] Of the napkin 1, the area in the longitudinal direction that overlaps with the wing adhesive portion 33 (crotch area CA) is the part that is likely to come into contact with the wearer's ostomy opening when worn. Therefore, by separating the pair of low-basis-weight portions 11g in this crotch area CA, the risk of the pair of low-basis-weight portions 11g sticking together with the main adhesive portion 32 can be reduced. As a result, when the napkin 1 is worn, it is easier to maintain the shape of the napkin 1 in the area that comes into contact with the wearer's crotch (crotch area CA), which reduces leakage of excrement and reduces the risk of causing discomfort to the wearer due to deformation.
[0102] Furthermore, it is preferable that a high-density section with a higher density of liquid-absorbing fibers than the surrounding area is provided between the low-basis-weight section 11gx on one side and the low-basis-weight section 11gy on the other side in the width direction. As shown in Figure 1, the napkin 1 of the packaging 100 of this embodiment has a plurality of circular compressed sections ee between the low-basis-weight section 11gx on one side and the low-basis-weight section 11gy on the other side in the width direction. The circular compressed sections ee are portions formed by compressing the top sheet 21, the second sheet 22, and the absorbent material 10 (core wrap sheet 12, absorbent core 11) in the thickness direction, and are high-density sections with a high density of liquid-absorbing fibers.
[0103] In this way, by providing a circular compressed section ee (high-density section) between one low-basis-weight section 11gx and the other low-basis-weight section 11gy in the width direction, the rigidity of the high-density section reduces deformation of the crotch area CA and the central part in the width direction of the napkin 1 in the packaged state of the packaging body 100. Therefore, it becomes easier to maintain the shape of the area that comes into contact with the wearer's anus when worn, and it becomes easier to improve the wearer's comfort when wearing the napkin.
[0104] As shown in Figures 2 and 5, a release sheet 103 is provided inside the packaging material 101 (outer packaging material) of the packaging body 100, and the packaging material 101 and the release sheet 103 are fixed together by a fixing part 104 to which adhesive is applied. In the unfolded state of such packaging body 100, it is preferable that at least a portion of the fixing part 104 is provided between a pair of low-basis-weight sections 11g in the width direction. In this embodiment, as shown in Figure 2, the unfolded packaging body 100 has a plurality of fixing parts 104 provided in the center in the width direction, spaced apart in the longitudinal direction. Each of these fixing parts 104 is provided between a pair of low-basis-weight sections 11g, and is located inside each low-basis-weight section 11g in the width direction.
[0105] In the packaging 100, the portion equipped with fixing parts 104 that secure the packaging material 101 and release sheet 103, in addition to the packaging material 101 and release sheet 103, has greater rigidity due to the fixing parts 104 than the portion equipped with only the packaging material 101 and release sheet 103. Therefore, in the packaged state of the packaging 100, deformation of the central part in the width direction, which is between the pair of low-basis-weight portions 11g of the napkin 1, is reduced, making it easier to maintain the shape of the area that comes into contact with the wearer's anus when worn, and improving the wearer's comfort when wearing the napkin.
[0106] It is preferable that the packaged body 100 in its packaged state has a portion where two low-basis-weight portions 11gx overlap when viewed in the thickness direction, and a portion where two low-basis-weight portions 11gy overlap when viewed in the thickness direction. Figure 11 is a schematic diagram showing a cross-section taken along the N-N arrow in Figure 3. Figure 11 is a schematic diagram showing the positions of the low-basis-weight portion 11gx and the high-basis-weight portion 11f of the absorbent core 11 of the napkin 1 at the N-N position in Figure 3 of the packaged body 100 in its packaged state, and the NN position in Figure 3 is NN in the unfolded state in Figure 1. In Figure 11, the dimensions etc. are not necessarily accurate. As shown in Figure 11, in the packaged state, the packaged body 100 of this embodiment has a portion where one first low-basis-weight portion 11gxa and one second low-basis-weight portion 11gxb overlap when viewed in the thickness direction. Furthermore, since the packaging body 100 and the napkin 1 have a symmetrical shape with respect to the center CC, the other side low-basis-weight portion 11gy also has a portion G in the packaging state where, when viewed in the thickness direction, the other side first low-basis-weight portion 11gya and the other side second low-basis-weight portion 11gyb overlap.
[0107] As a result, when a force is applied to the packaging 100 from the outside in the width direction while the packaging 100 is in its packaged state, the force acts on the one low-basis-weight section 11gx and the other low-basis-weight section 11gy before the region between the one low-basis-weight section 11gx and the other low-basis-weight section 11gy in the width direction, making it easier for the pair of low-basis-weight sections 11g to buffer the external force. Therefore, it becomes easier to maintain the shape of the region between the one low-basis-weight section 11gx and the other low-basis-weight section 11gy in the width direction, which can reduce leakage of excrement when worn and reduce the risk of causing discomfort to the wearer due to deformation.
[0108] Furthermore, at a predetermined position in the longitudinal direction of the napkin 1 in the unfolded packaging 100, it is preferable that the widthwise length of the low-basis-weight portion 11gx on one side is longer than the widthwise length of the linear compression portion ELx on one side. For example, at position AA in the longitudinal direction of the napkin 1 in the unfolded packaging 100 shown in Figure 1, when viewing the napkin 1 in the thickness direction, the compression portion ELx on one side overlaps with the low-basis-weight portion 11gx on one side, and the widthwise length dgx of the second low-basis-weight portion 11gxb on one side is longer than the widthwise length de of the compression portion ELx on one side.
[0109] The low-basis-weight section 11gx on one side is prone to deformation due to its low rigidity. However, by making the width of the low-basis-weight section 11gx longer than the width of the linear compression section ELx on one side, a relatively rigid linear compression section ELx is provided inside the low-basis-weight section 11gx, creating a core inside the low-basis-weight section 11gx. This reduces the risk of the low-basis-weight section 11gx being crushed even when force is applied from the outside in the width direction of the packaging body 100 in the packaged state.
[0110] ===Other Examples=== While embodiments of the present invention have been described above, these embodiments are intended to facilitate understanding of the present invention and are not intended to limit its interpretation. Furthermore, the present invention can be modified or improved without departing from its spirit, and it goes without saying that the present invention includes equivalents thereof.
[0111] In the above-described embodiment, as shown in Figure 1, in the unfolded state, both ends in the longitudinal direction of the second low-basis-weight portion (central low-basis-weight portion) 11gb (11gxb, 11gyb) having a portion that overlaps with the wing adhesive portion 33 in the longitudinal direction are inclined inward with respect to the longitudinal direction, but the embodiment is not limited to this. In the unfolded state, both ends in the longitudinal direction of the second low-basis-weight portion 11gb having a portion that overlaps with the wing adhesive portion 33 in the longitudinal direction may be inclined outward with respect to the longitudinal direction. In other words, the front end xbq and the rear end xbr of one side of the second low-basis-weight portion 11gxb may be inclined outward with respect to the longitudinal direction, and the central part in the longitudinal direction of the napkin 1 may have a curved shape in which it protrudes inward in the width direction (to the other side) more than the ends xbq and xbr in the longitudinal direction. Similarly, the front end xbq and rear end ybr of the other side second low basis weight section 11gyb may be inclined outward with respect to the longitudinal direction, and the other side second low basis weight section 11gyb may have a curved shape in which the central part in the longitudinal direction protrudes inward (to one side) in the width direction more than the ends ybq and ybr in the longitudinal direction.
[0112] In the napkin 1, the portion that overlaps with the wing adhesive portion 33 in the longitudinal direction is the part that is likely to come into contact with the wearer's anus when worn. Therefore, because both ends of the second low-basis-weight portion 11gb in the longitudinal direction are inclined outward with respect to the longitudinal direction, when force is applied from the outside in the width direction in the packaged and worn state, the force applied to the second low-basis-weight portion 11xb is first easily buffered by both ends xbq, xbr, ybq, and ybr in the longitudinal direction of the second low-basis-weight portion 11xb, thereby reducing the risk of the portion between the ends of the second low-basis-weight portion 11xb in the longitudinal direction being crushed.
[0113] In the napkin 1 of the above embodiment, the skin-side sheet portion and the non-skin-side sheet portion forming the joint portion 12s are made up of a core wrap sheet 12 (skin-side sheet portion 12a, non-skin-side sheet portion 12b), but the invention is not limited to this. For example, the absorbent body 10 (napkin 1) may be configured without a core wrap sheet 12. If the absorbent body 10 does not have a core wrap sheet 12, the second sheet 22 or top sheet 21 located on the skin side of the absorbent core 11 can be made up of a skin-side sheet portion, and the back sheet 31 can be made up of a non-skin-side sheet portion.
[0114] In the napkin 1 of the above-described embodiment, all low-basis-weight portions 11g are provided with an opening 11h and an adjacent portion 11n, but this is not limited to this. The low-basis-weight portions 11g may consist only of the opening 11h, or may not have an opening 11h.
[0115] In the above-described embodiment, the pair of low-basis-weight sections 11g and the linear compression section EL are each symmetrically shaped and arranged with respect to the center CC in the width direction, but the embodiment is not limited to this. The pair of low-basis-weight sections 11g and the linear compression section EL may each be shaped and arranged asymmetrically with respect to the center CC in the width direction.
