[0009] (1) Overview of the embodiment At least the following matters will become clear from the description of this specification and the accompanying drawings. A first aspect of the invention is an absorbent article having mutually orthogonal front-to-back, width, and thickness directions, a crotch region including the center in the front-to-back direction, a front waist region located forward of the crotch region, and a rear waist region located rear of the crotch region, an absorbent core disposed at least in the crotch region and having an absorbent material, and compressed portions compressing at least the absorbent core in the thickness direction. The absorbent core has a center region located in the middle of three equal regions obtained by dividing the absorbent core in the width direction at the center of the front-to-back direction of the absorbent article, and side regions extending from the outer edges of the center region to the outer edges of the absorbent core. The absorbent article has a center compressed region in which the compressed portions are disposed in the center region, and a first high-compression region in which the compressed portions are disposed at an area ratio higher than the overall center area ratio, which is the area ratio of the compressed portions to the entire center compressed region. The first high-compression region is disposed in the side region and has a length of at least 50% of the overall length of the absorbent core in the front-to-back direction. A first high-pressure region is disposed in the side region. The first high-pressure region is likely to improve the ability of the compressed portions to draw in and disperse bodily fluids. This can improve the ability to draw in and disperse bodily fluids in the side region. The center region is disposed opposite the excretory opening. The compressed portions are disposed in a lower area ratio in the center region than in the first high-pressure region. The presence of the compressed portions prevents the center region from becoming too hard. This can soften the contact with the excretory opening and improve the wearing comfort. Furthermore, because the compressed portions are disposed in a low area ratio in the center region, it is possible to improve rigidity while preventing the absorbent core from becoming too hard, maintaining its shape and allowing the absorbent core to continue to contact the excretory opening. This can improve the ability to draw in and disperse bodily fluids in the side region while softening the contact with the excretory opening in the center region and improving the wearing comfort.

[0010] According to a preferred embodiment, in the invention according to embodiment 2, the first high-pressure compression region is disposed over the entire area of ​​the absorbent core in the front-to-rear direction. According to this embodiment, since the first high-pressure compression region is disposed over the entire area of ​​the absorbent core in the front-to-rear direction, it is possible to obtain the effect of diffusing bodily fluids over the entire area of ​​the absorbent core in the front-to-rear direction, thereby making full use of the absorption capacity of the absorbent core.

[0011] According to a preferred aspect, the invention according to aspect 3 may have the following features in the invention according to aspect 1 or aspect 2. The invention comprises a first lattice region in the center region, in which the compressed portions are arranged in a lattice pattern, and a second lattice region in the side region, in which the compressed portions are arranged in a lattice pattern. The area ratio of the compressed portions in the first lattice region is lower than the area ratio of the compressed portions in the second lattice region. According to this aspect, because the area ratio of at least the first lattice region arranged in the center region is low, the presence of the compressed portions does not make the center region too stiff. This can soften the contact with the excretory opening, improving the wearing comfort. Furthermore, because the lattice-patterned compressed portions are arranged in the center region, the lattice-patterned compressed portions can improve the diffusion of bodily fluids while preventing the diaper from becoming too stiff. Furthermore, because the area ratio of the second lattice region arranged in the side region is high, the absorption and diffusion of bodily fluids in the side region can be improved.

[0012] According to a preferred aspect, the invention according to aspect 4 may have the following feature in the invention according to aspect 3: The first lattice region and the second lattice region are arranged at a distance from each other. According to this aspect, when an external force is applied to the absorbent core, the area where the first lattice region and the second lattice region are arranged at a distance deforms to absorb the force, maintaining the shapes of the first lattice region and the second lattice region, continuously improving the liquid absorption and diffusion properties, and allowing the absorbent core to continue to be applied to the excretory opening.

[0013] According to a preferred embodiment, the invention according to embodiment 5 may have the following features in the invention according to any one of embodiments 1 to 4. The area ratio of the compressed portions to the entire center region is lower than the area ratio of the compressed portions to the entire side regions. According to this embodiment, the center region does not become too stiff due to the presence of the compressed portions, thereby improving the fit to the body. Furthermore, the side regions are made more rigid due to the presence of the compressed portions, improving the absorption and diffusion of bodily fluids over a wide area.

[0014] According to a preferred embodiment, the invention according to Aspect 6 may be any of the inventions according to Aspects 1 to 5, and may have the following features. The absorbent core has a front widest section at the front end of the absorbent core, which is the longest section in the width direction of the absorbent core; a rear widest section at the rear end of the absorbent core, which is the longest section in the width direction of the absorbent core; and a waisted region between the front widest section and the rear widest section, where the length of the absorbent core in the width direction is shortened. The first high-compression region is disposed over the entire front-to-rear area of ​​the waisted region. The waisted region is pinched between the legs and is susceptible to forces directed inward in the width direction. Because the first high-compression region is provided over the entire front-to-rear area of ​​the waisted region, deformation of the side regions in the waisted region can be suppressed by the first high-compression region. Therefore, even when subjected to forces during wear, the shape of the side regions can be maintained, and the absorption and diffusion of bodily fluids can be maintained.

[0015] According to a preferred aspect, the invention according to aspect 7 may have the following characteristics in the invention according to aspect 6: The first high-compression region is arranged from the waist region to the rear widest portion and the front widest portion. According to this aspect, the first high-compression region is arranged to span the front widest portion and the rear widest portion, which suppresses deformation of the waist region as well as the front widest portion and the rear widest portion, thereby ensuring the area of ​​the absorbent core and ensuring absorption capacity.

[0016] According to a preferred embodiment, the invention according to embodiment 8 may have the following features in the invention according to any one of embodiments 1 to 7. The absorbent core has a minimum width portion where the widthwise length of the absorbent core is the shortest. The outer edge of the first compressed region in the widthwise direction is located widthwise inward of the narrowest imaginary line extending in the front-to-rear direction from the outer edge of the absorbent core at the minimum width portion. According to this embodiment, since the first compressed region is not positioned widthwise outward of the narrowest imaginary line, the rigidity of the outer portion of the absorbent core can be reduced, and the impact of the absorbent core can be softened. Uncomfortable sensations in the groin and buttocks can be reduced.

[0017] A ninth aspect of the invention relates to an absorbent article having a crotch region including a center in the front-to-back direction, a width direction, and a thickness direction, which are perpendicular to each other, a front waist region located forward of the crotch region, and a rear waist region located rearward of the crotch region, an absorbent core disposed at least in the crotch region and having an absorbent material, and compressed portions formed by compressing at least the absorbent core in the thickness direction. The absorbent core has a crotch region located in the center of three equal regions obtained by dividing the absorbent core in the front-to-back direction, a front region located forward of the crotch region, and a rear region located rearward of the crotch region. The absorbent article also has a crotch compression region in which the compression portions are disposed in the crotch region, and a second high compression region in which the compression portions are disposed at a higher area ratio than the overall crotch area ratio, which is the area ratio of the compression portions to the entire crotch compression region. The second high compression region is disposed in at least one of the front region and the rear region. According to this aspect, a second high-pressure compression region is provided in at least one of the front region and the rear region. The second high-pressure compression region is likely to improve the ability of the compression portions to draw in and disperse bodily fluids. This can improve the ability to draw in and disperse bodily fluids in at least one of the front region and the rear region. The crotch region is positioned opposite the excretory opening. The compression portions are arranged in the crotch region with a lower area ratio than the second high-pressure compression region. The presence of the compression portions prevents the crotch region from becoming too hard. This softens the contact with the excretory opening, improving the wearing comfort. Furthermore, because the compression portions are arranged in a low area ratio in the crotch region, the rigidity of the crotch region is increased while preventing the absorbent core from becoming too hard, allowing the shape of the absorbent core to be maintained and the absorbent core to continue to be in contact with the excretory opening.

[0018] According to a preferred embodiment, the invention according to embodiment 10 may have the following characteristics in the invention according to embodiment 9: The second compressed region reaches the outer edge of the absorbent core in the front-to-rear direction. According to this embodiment, bodily fluids can be diffused over a wide area up to the outer edge of the absorbent core, making effective use of the absorption capacity of the absorbent core.

[0019] According to a preferred embodiment, the invention according to embodiment 11 may have the following characteristics in the invention according to embodiment 9 or embodiment 10: The second compressed region reaches the outer edge of the absorbent core in the width direction. According to this embodiment, the second compressed region is provided up to the outer edge of the absorbent core, which allows bodily fluids to be diffused over a wide range up to the outer edge of the absorbent core, thereby making effective use of the absorption capacity of the absorbent core.

[0020] According to a preferred aspect, the invention according to aspect 12 may be the invention according to any one of aspects 9 to 11, and may have the following features. The garment comprises a third lattice region in the crotch region, in which the compressed portions are arranged in a lattice pattern; a fourth lattice region in the front region, in which the compressed portions are arranged in a lattice pattern; and a fifth lattice region in the rear region, in which the compressed portions are arranged in a lattice pattern. The area ratio of the compressed portions in the fourth lattice region is higher than the area ratio of the compressed portions in the third lattice region. The area ratio of the compressed portions in the fifth lattice region is higher than the area ratio of the compressed portions in the third lattice region. According to this aspect, the crotch region does not become too stiff due to the presence of the compressed portions, and the fit to the body can be improved. Furthermore, the absorption and diffusion of bodily fluids can be improved throughout the front region R58 and the entire rear region.

In the following description of the drawings, identical or similar parts are denoted by identical or similar reference numerals. However, it should be noted that the drawings are schematic and the ratios of the dimensions may differ from those of the actual product. Therefore, specific dimensions should be determined with reference to the following description. Furthermore, the drawings may include parts with different dimensional relationships and ratios.

[0022] FIG. 1 is a front view of an absorbent article 10 according to an embodiment, and FIG. 2 is a plan view of the absorbent article 10 in an unfolded state. The plan view shown in FIG. 1 is a view of the absorbent article in an extended state, as seen from the skin side. Note that the extended state in the present invention refers to a state in which the absorbent article 10 is extended to a state in which no wrinkles are formed when a side joining portion 60, which will be described later, is extended. Furthermore, in the present invention, the natural state refers to a state in which, in the case of an absorbent article housed in a package, the absorbent article is removed from the package and left in an atmosphere of 20°C±2°C and a relative humidity of 60%±5%RH for 24 hours. FIG. 3 is a cross-sectional view taken along line AA shown in FIG. 2.

[0023] The absorbent article 10 may be any absorbent article that covers the waist of a wearer, and may be, for example, a disposable diaper. The absorbent article 10 may be a pants-type absorbent article or an open-type (tape-type) absorbent article. This embodiment is a pants-type absorbent article. The absorbent article 10 has a front-to-rear direction L, a width direction W, and a thickness direction T that are perpendicular to each other. The front-to-rear direction L is defined by the direction extending toward the front and rear of the body. In other words, the front-to-rear direction L is the direction extending from front to back in the opened absorbent article 10. The absorbent article 10 also has a thickness direction T that is perpendicular to both the front-to-rear direction L and the width direction W. The thickness direction T extends between a skin side T1 that faces the wearer and a non-skin side T2 that faces away from the wearer.

[0024] The absorbent article 10 has a crotch region S3, a front waist region S1 located in front of the crotch region S3, and a rear waist region S2 located behind the crotch region S3. The front waist region S1 and the rear waist region S2 form waist regions that cover the waist of the wearer. The front waist region S1 is a region that is placed against the wearer's stomach. The rear waist region S2 is a region that is placed against the wearer's back. The crotch region S3 is a region that is located between the front waist region S1 and the rear waist region S2 under the crotch of the wearer.

[0025] The absorbent article 10 may be provided with a pair of side joining sections 60 joining the outer sides of the front waistline region S1 and the rear waistline region S2. The absorbent article 10 is folded in two around a fold line FL located at the center of the absorbent article 10 in the front-to-rear direction L, and joined in this folded state by the side joining sections 60 to form a pants-like shape. The fold line FL extends in the width direction W, and is a fold line along which the absorbent article 10 is folded in two so that the skin-side surfaces T1 of the absorbent article 10 face each other. In this embodiment, the fold line FL coincides with the center of the absorbent article in the front-to-rear direction L. The side joining sections 60 are defined by the portions where the outer sides of the front waistline region S1 and the outer sides of the rear waistline region S2 are engaged with each other, and may extend along the front-to-rear direction L in each of the front waistline region S1 and the rear waistline region S2.

[0026] Here, the outer portion in the present invention refers to a portion occupying a certain range in the width direction W including an edge in the width direction W, and the outer edge refers to an edge in the width direction W. Furthermore, the outer edge in the present invention refers to an edge located on the outer side in the front-to-back direction L, and the inner edge refers to an edge located on the inner side in the front-to-back direction L. Here, FIG. 1 shows a state in which the side joints 60 are joined, and FIG. 2 shows a state in which the side joints 60 are released and the absorbent article 10 is unfolded. With the side joints 60 formed, the absorbent article 10 is formed with a waist opening 62 through which the wearer's waist is passed and a pair of leg openings 66 through which the wearer's legs are inserted. The waist opening 62 is defined by the front edge of the front waist region S1 and the rear edge of the rear waist region S2. The boundary between the front waist region S1 and the crotch region S3 may be defined by the rear end edge of the side joint 60 provided in the front waist region S1, and the boundary between the rear waist region S2 and the crotch region S3 may be defined by the front end edge of the side joint 60 provided in the rear waist region S2.

[0027] The absorbent article 10 has an absorbent core 50 disposed at least in the crotch region S3 and containing an absorbent material. FIG. 4 is a plan view of the absorbent core 50. The absorbent core 50 may contain, for example, fluff pulp, superabsorbent polymer (SAP), or a mixture thereof. The absorbent core 50 is disposed at least in the crotch region S3. Preferably, the absorbent core 50 may extend from the front waist region S1 to the rear waist region S2 in the front-to-back direction L. The absorbent core 50 may be covered by a core wrap (not shown). As shown in FIG. 4, the absorbent core 50 may have a waist region 55 between the front and rear ends of the absorbent core 50, where the length of the absorbent core 50 in the width direction W is shortened. The waist region 55 is located between a front maximum width portion 50FM at the front end of the absorbent core 50 and a rear maximum width portion 50RM at the rear end of the absorbent core 50. The constricted region 55 may have a shortest width portion 55N, which has the shortest widthwise length of the absorbent core 50, and a widening region 56, which is located outside the shortest width portion 55N in the front-to-back direction L and in which the length in the widthwise direction W of the absorbent core 50 increases toward the outside in the front-to-back direction L.

[0028] The absorbent core 50 has a center region R51 located in the middle of the regions obtained by dividing the absorbent core 50 into three equal parts in the width direction at the center of the front-rear direction L of the absorbent article 10, and side regions R52 extending from the outer edges of the center region R51 to the outer edges of the absorbent core 50. At the center of the front-rear direction L of the absorbent article 10, the widthwise lengths of each region are the same. However, in an embodiment having a constricted region 55 as in the present embodiment, the length in the widthwise direction W of the outer edge of the absorbent core 50 is longer than the center of the absorbent core 50 in the front-rear direction L, so the lengths in the widthwise direction W of each region at the outer edge of the absorbent core 50 are different. At the outer edge of the absorbent core 50, the length in the widthwise direction W of the side regions R52 is longer than the length in the widthwise direction W of the center region R51.

[0029] The absorbent core 50 has a crotch region R57 located in the center of three regions obtained by dividing the absorbent core 50 into three equal parts in the front-to-back direction L, a front region R58 located forward of the crotch region R57, and a rear region R59 located rearward of the crotch region R57. The crotch region R57, the front region R58, and the rear region R59 are formed by three regions obtained by dividing the absorbent core 50 into three equal parts in the front-to-back direction L, and all have the same length in the front-to-back direction L. The front region R58 is the region between the front edge of the crotch region R57 and the front edge of the absorbent core 50, and the rear region R59 is the region between the rear edge of the crotch region R57 and the rear edge of the absorbent core 50.

The top sheet 41 and the non-skin side sheet 43 may be made of nonwoven fabric. The back sheet 42 may be made of film. The absorbent main body 40 may be configured as a separate body from the waist sheet arranged in the waist region.

[0031] The absorbent article 10 has an exterior body 30 that is located closer to the wearer's skin side T2 than the absorbent main body 40 and covers the wearer's waist in the rear waist region S2 and front waist region S1. The exterior body 30 only needs to be located in at least the rear waist region S2 and the front waist region S1, and may also be located across the crotch region S3. The exterior body has multiple waist sheets. The waist sheets are sheets located in the waist region other than the absorbent main body 40. The waist sheets may include a first waist sheet 35 and a second waist sheet 36 that is located closer to the wearer's skin side T2 than the first waist sheet 35. The first waist sheet 35 and the second waist sheet 36 may be made of nonwoven fabric. The second waistline sheet 36 may have a non-folded portion 361 located closer to the skin side T2 than the first waistline sheet 35, and a folded portion 362 folded back to the skin side T1 from the waistline opening 62 (the front end edge of the front waistline region S1 and the rear end edge of the rear waistline region S2). The folded portion 362 of the second waistline sheet 36 may be located on the skin side T1 of the first waistline sheet 35 and the absorbent main body 40.

[0032] 3, the absorbent article 10 is provided with a front joining region R31 that joins the outer body 30 and the absorbent main body 40 on the front waistline region S1 side, and a rear joining region R32 that joins the outer body 30 and the absorbent main body 40 on the rear waistline region S2 side. The front joining region R31 and the rear joining region R32 are arranged on the non-skin side of the absorbent main body 40. The front joining region R31 and the rear joining region R32 are spaced apart in the front-to-rear direction L, and may extend along the width direction W.

[0033] The outer casing 30 may have waist elastic members that stretch in the width direction W. The waist elastic members may be made of rubber thread that stretches in the width direction W or elastic sheets that stretch in the width direction W. In this embodiment, the waist elastic members are made of rubber thread, and multiple waist elastic members may be arranged in each of the front waist region S1 and the rear waist region S2 at intervals in the front-to-back direction L. The waist elastic members only need to be arranged in at least the waist region, and may be arranged across the waist region and the crotch region. In this embodiment, the waist elastic members are arranged across the rear waist region S2 and the crotch region S3, and include leg elastic members 38 arranged along the leg openings 66. The leg elastic members 38 curve from the outer side of the rear waist region S2 in the width direction toward the inside in the width direction W, and then toward the inside in the front-to-back direction (toward the crotch region). Three leg elastic members 38 are provided in the rear waist region S2.

[0034] The waist elastic members may include a front continuous elastic member 31 that is continuously disposed from one end to the other in the width direction of the front waist region S1 and stretches in the width direction, and a rear continuous elastic member 32 that is continuously disposed from one end to the other in the width direction W of the rear waist region S2 and stretches in the width direction. All of the waist elastic members (including the leg elastic members 38) in this embodiment are continuous elastic members.

[0035] The absorbent article 10 has at least a compressed section 80 that compresses the absorbent core 50 in the thickness direction T. The compressed section 80 may compress only the absorbent core 50, or may compress the core wrap together with the absorbent core 50. For convenience, the compressed section is illustrated as a blackened area in the cross-sectional view, but in an actual product, it is an area where the absorbent material is compressed and recessed in the thickness direction. The compressed section 80 may be recessed from the non-skin side T2 of the absorbent core 50 toward the skin side T1, or from the skin side T1 of the absorbent core 50 toward the non-skin side T2. That is, the compressed section 80 may be formed by pressing the non-skin side T2 surface of the absorbent core 50 toward the skin side T1, or by pressing the skin side T1 surface of the absorbent core 50 toward the non-skin side T2. The compressed section 80 in this embodiment is recessed from the non-skin side T2 of the absorbent core 50 toward the skin side T1.

[0036] The compression portions 80 may include a center compression portion 81 arranged in the center region R51, side compression portions 82 arranged in the side regions R52, a crotch compression portion 87 arranged in the crotch region R57, a front compression portion 88 arranged in the front region R58, and a rear compression portion 89 arranged in the rear compression region R89. The compression portions 80 may be arranged across the center region R51 and the side regions R52, or may be arranged in each of the center region R51 and the side regions R52 and spaced apart. The compression portions 80 may be arranged across the crotch region R57 and the front region R58, or may be arranged in each of the crotch region R57 and the front region R58 and spaced apart. The compression portions 80 may be arranged across the crotch region R57 and the rear region R59, or may be arranged in each of the crotch region R57 and the rear region R59 and spaced apart.

[0037] The absorbent article 10 of the present embodiment is configured to improve the liquid absorption and diffusion properties while softening the contact with the excretory opening to improve the wearing comfort. There are roughly two configurations for improving the liquid absorption and diffusion properties while softening the contact with the excretory opening to improve the wearing comfort. The first configuration will be described in the first embodiment, and the second configuration will be described in the second embodiment described below.

[0038] In the first embodiment, the absorbent article 10 has a center compressed region R81 in which compressed sections 80 are arranged in the center region R51, a side compressed region R82 in which compressed sections 80 are arranged in the side region R52, and a first high compression region HR1 in which compressed sections are arranged at an area ratio higher than the overall center area ratio, which is the area ratio of compressed sections to the entire center compressed region. The compressed region is a region in which compressed sections 80 are arranged, and is a region of a certain range that includes compressed sections in a certain pattern. The compressed region may have a single compressed section (for example, a continuous linear compressed section) arranged therein, or may have an array of multiple compressed sections (for example, a lattice-shaped array of compressed sections, as described below) arranged therein.

[0039] The center compressed region R81 is a region in which the center compressed portions 81 are arranged. In this embodiment, only the compressed portions that make up the first lattice region R71 (described later) are arranged in the center region R51, so the center compressed region R81 and the first lattice region R71 are the same region. However, in a modified example, if compressed portions other than those that make up the first lattice region R71 are arranged in the center region R51, the center compressed region is configured to include the first lattice region R71 and the region in which the other compressed portions are arranged. Also, the center compressed region R81 may not be provided with a first lattice region, and compressed portions other than those in a lattice pattern may be arranged. In this embodiment, the widthwise range of the center compressed region R81 is the range sandwiched between the outer edges on both sides of the lattice-shaped center compressed portion 81. The range of the center compression region R81 in the front-to-back direction L is the range sandwiched between the outer edges on both sides of the lattice-shaped center compression portion 81, and since the center compression portion 81 is arranged up to both outer edges of the absorbent core 50, it is the range sandwiched between the front and rear edges of the absorbent core 50.

[0040] The side compression region R82 is a region where the side compression sections 82 are arranged. In this embodiment, only the compression sections that constitute the second lattice region R72 (described later) are arranged in the side region R52, so the side compression region R82 and the second lattice region R72 are the same region. However, in a modified example, if compression sections other than those that constitute the second lattice region R72 are arranged in the side region R52, the side compression region R82 is configured to include the second lattice region R72 and a region where the other compression sections are arranged. Also, the side compression region R82 may not be provided with the second lattice region R72, and compression sections other than those in a lattice pattern may be arranged. In this embodiment, the range of the side compression region R82 in the width direction W is the range sandwiched between the outer edges on both sides of the lattice-shaped side compression sections 82. The range of the side compression region R82 in the front-to-back direction L is the range sandwiched between the outer edges on both sides of the lattice-shaped side compression portion 82, and since the side compression portion 82 is arranged up to both outer edges of the absorbent core 50, it is the range sandwiched between the front and rear edges of the absorbent core 50.

[0041] The first high compression region HR1 is a region in which the compressed portions 80 are arranged at a higher area ratio than the overall center area ratio. In this embodiment, the first high compression region HR1 is the same region as the second lattice region R72 and the side compression region R82. The area ratio of the compressed portions is the ratio of the area in which the compressed portions are arranged. When calculating the area ratio of the compressed portions, the area of ​​the compressed regions (the entire area surrounding the compressed portions) and the area of ​​the compressed portions (the area of ​​only the compressed portions) are measured, and the ratio can be calculated as the area of ​​the compressed portions / the area of ​​the compressed regions. The overall center area ratio is the area ratio of the compressed portions to the overall area of ​​the center compression region R81. When there is one center compressed region R81, as in the present embodiment, the overall center area ratio can be calculated from the area ratio of that one center compressed region R81. However, when there are multiple center compressed regions R81, it can be calculated by dividing the total area of ​​the compressed regions (the total area of ​​the center compressed regions in multiple regions) by the total area of ​​the compressed regions (the total area of ​​the center compressed regions in multiple regions). In other words, when there are multiple center compressed regions R81, the average area ratio is used. Furthermore, the area of ​​the center compressed region R81 does not include the area of ​​the center region other than the center compressed region R81, for example, the region between the center compressed region R81 and the outer edge of the center region.

[0042] According to this embodiment, the first high-pressure region HR1 is disposed in the side region R52 and has a length of 50% or more of the overall length of the absorbent core 50 in the front-to-rear direction L. The first high-pressure region HR1 is likely to improve the bodily fluid absorption and diffusion properties of the compressed portions. In the side region R52, the bodily fluid absorption and diffusion properties can be improved over more than half of the absorbent core 50 in the front-to-rear direction. The center region R51 is disposed opposite the excretory opening. The compressed portions are disposed in the center region R51 at a lower area ratio than the first high-pressure region HR1. The center region R51 does not become too hard due to the presence of the compressed portions. This softens the contact with the excretory opening, improving the wearing comfort. Furthermore, because the compressed portions are disposed at a low area ratio in the center region R51, the rigidity can be improved while preventing the absorbent core 50 from becoming too hard, allowing the absorbent core 50 to maintain its shape and continue to be in contact with the excretory opening. Therefore, the center region R51 can soften the impact on the excretory opening, improving the wearing comfort, while the side regions R52 can improve the absorption and diffusion of bodily fluids.

[0043] The first high compression region HR1 may extend in the front-to-rear direction L. Here, the shape extending in the front-to-rear direction L may be a straight line along the front-to-rear direction L, or may have a wavy or other shape that has portions that are inclined with respect to the front-to-rear direction L, but extends in the front-to-rear direction as a whole. Note that the shape extending in the front-to-rear direction is not limited to a configuration that is parallel to the front-to-rear direction L, but may also be a configuration that is slightly inclined (for example, less than 10 degrees, preferably less than 5 degrees) with respect to the front-to-rear direction.

[0044] The first compressed region HR1 may be disposed at least in the crotch region R57. This is because the crotch region R57 is easily disposed opposite the excretory opening. Preferably, the first compressed region HR1 may be disposed across the crotch region R57 and the rear region R59. According to this embodiment, the first compressed region HR1 is disposed across the crotch region R57 and the rear region R59, thereby improving the diffusion of bodily fluids in the regions where urine and feces are excreted.

[0045] The first high-compression region HR1 may be disposed across the entire area of ​​the constricted region 55 in the front-to-back direction L. The first high-compression region HR1 extends in the front-to-back direction L and may be disposed forward of the front edge of the constricted region 55 and behind the rear edge of the constricted region 55. The constricted region 55 is pinched between the legs and is likely to receive forces directed inward in the width direction W. Because the first high-compression region HR1 is provided across the entire area of ​​the constricted region 55 in the front-to-back direction L, the first high-compression region HR1 can suppress deformation of the side regions R52 in the constricted region 55. Therefore, even when forces are applied while wearing the garment, the shape of the side regions R52 can be maintained, and bodily fluid diffusion can be maintained.

[0046] The first high-compression region HR1 may be arranged across the waist region 55 to the rear widest portion 50RM and the front widest portion 50FM. Since the first high-compression region is arranged across the front widest portion and the rear widest portion, deformation of the waist region is suppressed, and deformation of the front widest portion and the rear widest portion is suppressed, ensuring the area of ​​the absorbent core and ensuring absorption capacity.

[0047] The first high-pressure compression region HR1 may be disposed over the entire front-to-rear direction of the absorbent core 50. Since the first high-pressure compression region is disposed over the entire front-to-rear direction of the absorbent core 50, it is possible to obtain the effect of diffusing bodily fluids over the entire front-to-rear direction of the absorbent core and utilizing the absorption capacity of the absorbent core. The first high-pressure compression region HR1 in this embodiment is disposed over the entire front-to-rear direction of the absorbent core, spanning the crotch region R57, front region R58, and rear region R59.

[0048] The range of the first high-compression region HR1 in the width direction W is not limited, as long as at least a portion of the first high-compression region HR1 is located in the side region R52. The first high-compression region HR1 may be located only in the side region R52 and not in the center region R51, or may straddle the center region R51 and the side region R52. In this embodiment, the first high-compression region HR1 is located only in the side region R52. The length of the first high-compression region HR1 in the width direction W may be 50% or more of the length of the side region R52 in the width direction W.

[0049] The outer edge of the first compressed region HR1 in the width direction W may be located widthwise inward of the narrowest imaginary line EL55 extending in the front-to-rear direction from the outer edge of the absorbent core 50 at the shortest width portion 55N. According to this embodiment, the first compressed region is not located widthwise outward of the narrowest imaginary line, so the rigidity of the outer portion of the absorbent core 50 can be reduced, and the impact of the absorbent core 50 can be softened. This can reduce discomfort in the groin and buttocks.

[0050] In a configuration having a waisted region 55 as in this embodiment, the compressed portions do not have to be located on the outer sides of the absorbent core 50 at the rear widest portion 50RM, and they do not have to be located on the outer sides of the absorbent core 50 at the front widest portion 50FM. The outer sides of the absorbent core 50 at the front widest portion 50FM are likely to come into contact with the groin, and the outer sides of the absorbent core 50 at the rear widest portion 50RM are likely to come into contact with the bulge of the buttocks. By not providing compressed portions in the areas that come into contact with the groin and buttocks, the rigidity of these areas is prevented from increasing, improving the wearing comfort.

[0051] The absorbent article 10 may have a first lattice region R71 in the center region R51, in which compressed portions are arranged in a lattice pattern, and a second lattice region R72 in the side region R52, in which compressed portions are arranged in a lattice pattern. The area ratio of the compressed portions in the first lattice region R71 may be lower than the area ratio of the compressed portions in the second lattice region R72. Because the area ratio of the first lattice region R71 arranged in the center region R51 is low, the presence of the compressed portions 80 does not make the center region R51 too stiff. This can soften the contact with the excretory opening, improving the wearing comfort. Furthermore, because the compressed portions are arranged in the center region R51, the lattice-shaped compressed portions can improve the diffusion of bodily fluids while preventing the garment from becoming too stiff. Furthermore, because the area ratio of the second lattice region R72 arranged in the side region R52 is high, the absorption and diffusion of bodily fluids in the side region R52 can be improved. The compressed portions of the second lattice region R72 of this embodiment have a shorter lattice pitch and are more densely arranged than the compressed portions of the first lattice region R71. The second lattice region R72 may constitute the first high-compression region HR1, or may be provided separately from the first high-compression region HR1. The second lattice region R72 of this embodiment constitutes the first high-compression region HR1.

[0052] The first lattice region R71 and the second lattice region R72 may be spaced apart. According to this embodiment, when an external force is applied to the absorbent core 50, the spaced-apart region of the first lattice region R71 and the second lattice region R72 deforms, absorbing the force and maintaining the shapes of the first lattice region R71 and the second lattice region R72, thereby continuously improving the liquid absorption and diffusion properties and keeping the absorbent core in contact with the excretory opening. In this embodiment, the first lattice region R71 and the second lattice region R72 are spaced apart in the width direction W.

[0053] The area ratio of the compressed portions 80 in the entire center region R51 may be lower than the area ratio of the compressed portions 80 in the entire side regions R52. The area ratio of the compressed portions 80 in the entire center region R51 can be calculated by dividing the total area of ​​the compressed portions 80 arranged in the center region R51 by the total area of ​​the center region R51 (including areas other than the compressed regions), and the area ratio of the compressed portions in the entire side regions R52 can be calculated by dividing the total area of ​​the compressed portions arranged in the side regions R52 by the total area of ​​the side regions R52 (including areas other than the compressed regions). According to this embodiment, the center region R51 does not become too stiff due to the presence of the compressed portions, thereby improving its fit to the body. Furthermore, the presence of the compressed portions increases the rigidity of the side regions R52, improving the absorption and diffusion of bodily fluids over a wide area.

[0054] (3) Absorbent article according to the second embodiment Next, an absorbent article according to a second embodiment will be described with reference to FIG. 5. FIG. 5 is a plan view of an absorbent core 50A of the absorbent article according to the second embodiment. The absorbent article according to the second embodiment has a second aspect. In the following description, the same components as those in the above-described embodiment will be denoted by the same reference numerals and will not be described again. In the second embodiment, only the absorbent core 50 will be illustrated and described, but the other components of the absorbent article, such as the outer casing, can be the same as those of the absorbent article according to the first embodiment.

[0055] In the second embodiment, the absorbent article has a crotch compression region R87 in which crotch compression sections 87 are arranged in the crotch region R57. In this embodiment, only compression sections that constitute a third lattice region R73 (described later) are arranged in the crotch region R57, so the crotch compression region R87 and the third lattice region R73 are the same region. However, in a modified embodiment, when compression sections other than those that constitute the third lattice region R73 are arranged in the crotch region R57, the crotch compression region R87 is configured to include the third lattice region R73 and an area in which the other compression sections are arranged. Also, the third lattice region R73 may not be provided in the crotch compression region R87, and compression sections other than those in a lattice pattern may be arranged. In this embodiment, the widthwise range of the crotch compression region R87 is the range sandwiched between the outer edges on both sides of the lattice-shaped crotch compression section 87. The range of the crotch compressing region R87 in the front-rear direction L is the range sandwiched between the outer edges on both sides of the lattice-shaped crotch compressing portion 87.

[0056] In the second embodiment, the absorbent article has at least one of a front compression region R88 in which front compression sections 88 are arranged in the front region R58, and a rear compression region R89 in which rear compression sections 89 are arranged in the rear region R59. In this embodiment, only compression sections constituting the fourth lattice region R74 (described later) are arranged in the front region R58, so the front compression region R88 and the fourth lattice region R74 are the same region. However, in a modified example, if compression sections other than those constituting the fourth lattice region R74 are arranged in the front region R58, the front compression region R88 is configured to include the fourth lattice region R74 and a region in which the other compression sections are arranged. Alternatively, the front compression region R88 may not be provided with a fourth lattice region, and may instead have compression sections other than those in a lattice pattern. Furthermore, the front compression region R88 in this embodiment is the same region as the second high compression region HR2. The widthwise range of the front compressed region R88 is the range sandwiched between the outer edges on both sides of the lattice-shaped front compressed section 88. The front-to-rear range of the front compressed region is the range sandwiched between the outer edges on both sides of the lattice-shaped front compressed section 88. The front edge of the front compressed region R88 coincides with the front edge of the absorbent core.

[0057] In this embodiment, only the compressing sections that constitute the fifth lattice region R75, which will be described later, are arranged in the rear region R59, and therefore the rear compressing region R89 and the fifth lattice region R75 are the same region. However, in a modified example, when compressing sections other than those that constitute the fifth lattice region R75 are arranged in the rear region R59, the rear compressing region R89 is configured to include the fifth lattice region R75 and a region in which other compressing sections are arranged. Furthermore, the rear compressing region R89 may not be provided with the fifth lattice region R75, and may instead have compressing sections other than those in a lattice pattern. Furthermore, the rear compressing region R89 in this embodiment is the same region as the second high-compression region HR2. The rear compressing region R89 in this embodiment is the same region as the fifth lattice region R75, which will be described later. The widthwise range of the rear compressing region R89 is the range sandwiched between the outer edges on both sides of the lattice-shaped rear compressing section 89. The range in the front-to-rear direction of the rear compressed region R89 is the range sandwiched between the outer edges on both sides of the lattice-shaped rear compressed portion 89. The rear edge of the rear compressed region coincides with the rear edge of the absorbent core.

[0058] In the second embodiment, the absorbent article has a second high-compression region HR2. The second high-compression region HR2 has compressed portions arranged at a higher area ratio than the overall crotch area ratio, which is the area ratio of compressed portions to the entire crotch compression region R87. The overall crotch area ratio can be calculated based on the overall center area ratio. The second high-compression region HR2 is arranged in at least one of the front region R58 and the rear region R59. Preferably, the second high-compression region HR2 may be arranged in both the front region R58 and the rear region R59. In this embodiment, two second high-compression regions HR2 are provided. The first second high-compression region HR2 is in the same region as the fourth lattice region R74 and the front compression region R88 in the front region R58. The second second high-compression region HR2 is in the same region as the fifth lattice region R75 and the rear compression region R89 in the rear region R59.

[0059] A second high-pressure compression region HR2 is provided in at least one of the front region R58 and the rear region R59. The second high-pressure compression region HR2 is likely to improve the ability of the compressed portions to draw in and disperse bodily fluids. This improves the ability to draw in and disperse bodily fluids in at least one of the front region R58 and the rear region R59. The crotch region R57 is positioned opposite the excretory opening. The compressed portions are arranged in a lower area ratio in the crotch region R57 than in the second high-pressure compression region HR2. The presence of the compressed portions prevents the crotch region R57 from becoming too hard. This softens the contact with the excretory opening, improving the wearing comfort. Furthermore, because the compressed portions are arranged in a low area ratio in the crotch region R57, the rigidity of the crotch region R57 is increased while preventing the absorbent core 50 from becoming too hard, allowing the absorbent core 50 to maintain its shape and continue to contact the excretory opening.

[0060] The range of the second high-compression region HR2 in the front-to-rear direction L is not limited, as long as at least a portion of the second high-compression region HR2 is located in the front region R58 or the rear region R59. The second high-compression region HR2 may be located in the front region R58 without being located in the crotch region R57, or may straddle the crotch region R57 and the front region R58, or may be located in the rear region R59 without being located in the crotch region R57, or may straddle the crotch region R57 and the rear region R59. The second high-compression region HR2 in the second embodiment is located in both the front region R58 and the rear region R59. The second high-compression region HR2 may straddle the center of the absorbent core 50 in the front-to-rear direction L. The length in the front-to-rear direction L of the second high-compression region HR2 located in the front region R58 may be 50% or more of the length in the front-to-rear direction L of the front region R58. The length in the front-rear direction L of the second high compression region HR2 arranged in the rear region R59 may be 50% or more of the length in the front-rear direction L of the rear region R59.

[0061] The second high-pressure compression region HR2 may reach the outer edge in the front-to-rear direction L of the absorbent core 50. More specifically, the second high-pressure compression region HR2 in the front region R58 may reach the front edge of the absorbent core 50, and the second high-pressure compression region HR2 in the rear region R59 may reach the front edge of the absorbent core 50. According to this embodiment, bodily fluids can be diffused over a wide range up to the outer edge of the absorbent core, and the absorption capacity of the absorbent core can be effectively utilized.

[0062] The outer edge of the second compressed region HR2 in the width direction W may be located inside in the width direction W of the narrowest imaginary line EL55 extending from the outer edge of the absorbent core 50 at the shortest width part 55N in the front-to-rear direction L. According to this embodiment, since the second compressed region HR2 is not located outside in the width direction of the narrowest imaginary line EL55, the rigidity of the outer part of the absorbent core 50 can be reduced, and the impact of the absorbent core 50 can be softened.

[0063] The second high-compression region HR2 may be spaced apart from the outer edge of the absorbent core 50 in the width direction W. Preferably, the second high-compression region HR2 may be spaced apart from the outer edge of the absorbent core 50 in the width direction W at the center position of the absorbent core 50 in the front-to-rear direction L. According to this embodiment, since the second high-compression region HR2 is not provided on the outer edge of the absorbent core 50 in the width direction, the region between the outer edge of the absorbent core 50 in the width direction W and the second high-compression region HR2 is easily deformed and easily positioned along the body. The distance between the second high-compression region HR2 and the outer edge of the absorbent core 50 may be 5 mm or more, preferably 10 mm or more.

[0064] In a modified example, the second high-pressure compression region HR2 may reach the outer edge of the absorbent core 50 in the width direction. According to this embodiment, the second high-pressure compression region HR2 is provided up to the outer edge of the absorbent core 50, which allows bodily fluids to be diffused over a wide range up to the outer edge of the absorbent core, thereby making effective use of the absorption capacity of the absorbent core. The second high-pressure compression region HR2 may be arranged across the outer edge of both sides of the absorbent core 50 in the width direction. In other words, the second high-pressure compression region HR2 may be arranged across the entire width of the absorbent core.

[0065] The absorbent article 10 may have a third lattice region R73 in the crotch region R57, in which compressed portions are arranged in a lattice pattern, a fourth lattice region R74 in the front region R58, and a fifth lattice region R75 in the rear region R59, in which compressed portions are arranged in a lattice pattern. The area ratio of the compressed portions in the fourth lattice region R74 may be higher than the area ratio of the compressed portions in the third lattice region R73, and the area ratio of the compressed portions in the fifth lattice region R75 may be higher than the area ratio of the compressed portions in the third lattice region R73.

[0066] The high area ratio of the fourth lattice region R74 arranged in the front region R58 and the high area ratio of the fifth lattice region R75 arranged in the rear region R59 improves the absorption and diffusion of bodily fluids in the front and rear regions. Furthermore, the low area ratio of the third lattice region R73 arranged in the crotch region R57 prevents the crotch region R57 from becoming too stiff due to the presence of the compressed portions. This softens the impact on the excretory portion, improving the wearing comfort. The compressed portions of the fourth lattice region R74 and the fifth lattice region R75 have a shorter lattice pitch and are more densely arranged than the compressed portions of the third lattice region R73. The fourth lattice region R74 and the fifth lattice region R75 may constitute the second compressed region HR2, or may be provided separately from the second compressed region HR2. In this embodiment, the fourth lattice region R74 and the fifth lattice region R75 constitute the second compressed region HR2.

[0067] The third lattice region R73 and the fourth lattice region R74 may be spaced apart, and the third lattice region R73 and the fifth lattice region R75 may be spaced apart. In this embodiment, the third lattice region R73 and the fourth lattice region R74 are spaced apart in the front-to-back direction L, and the third lattice region R73 and the fifth lattice region R75 are spaced apart in the front-to-back direction L. According to this aspect, when an external force is applied to the absorbent core 50, the area where the lattice regions are spaced apart deforms, thereby absorbing the force and making it easier to maintain the shape of each lattice region.

[0068] The area ratio of the compressed portions in the entire front region R58 may be higher than the area ratio of the compressed portions in the entire crotch region R57, and the area ratio of the compressed portions in the entire rear region R59 may be higher than the area ratio of the compressed portions in the entire crotch region R57. The area ratios of the compressed portions in the entire crotch region R57, the area ratios of the compressed portions in the entire front region R58, and the area ratios of the compressed portions in the entire rear region R59 can be calculated based on the area ratios of the compressed portions in the entire center region and the area ratios of the compressed portions in the entire side regions. According to this embodiment, the crotch region R57 does not become too stiff due to the presence of the compressed portions, improving the fit to the body. Furthermore, the absorption and diffusion of bodily fluids can be improved throughout the entire front region R58 and rear region R59.

[0069] (4) Absorbent articles according to modified examples Next, an absorbent core of an absorbent article according to a modified example will be described with reference to Fig. 6. Fig. 6(A) is a plan view of an absorbent core 50B according to a modified example 1. The absorbent core 50B according to the modified example 1 is provided with compressed regions in which compressed portions are arranged in different patterns. The compressed regions R801 of the first pattern have a higher area ratio of compressed portions than the compressed regions R802 of the second pattern. The compressed regions R801 of the first pattern are arranged on the outer sides in the front-to-rear direction and on the sides in the width direction of the absorbent core. The compressed regions R801 of the first pattern are arranged in at least the side regions R52, the front region R58, and the rear region R59, and constitute a first high-pressure region HR1 and a second high-pressure region HR2.

[0070] 6(B) is a plan view of an absorbent core 50C according to Modification 2. The absorbent core 50C according to Modification 2 has a compressed region R803 in which the compressed portions are arranged in a grid pattern, and a compressed region R804 in which linear compressed portions are arranged. The grid-shaped compressed region R803 is arranged across the entire absorbent core. The compressed region R804 has linear compressed portions that occupy a higher area ratio than the grid-shaped compressed region R803. The compressed region R804 is arranged in the side region R52, and constitutes a first high-pressure region HR1. Because the area ratio of the compressed portions in the crotch region R57, the area ratio of the compressed portions in the front region R58, and the area ratio of the compressed portions in the rear region R59 are the same, the absorbent article according to Modification 2 does not have a second high-pressure region HR2.

[0071] FIG. 6(C) is a plan view of an absorbent core 50D according to Modification 3. The absorbent core 50D according to Modification 3 has a compressed region R805 in which the compressed regions are arranged in a grid pattern, and a compressed region R806 in which linear compressed regions are arranged. The compressed region R806 has linear compressed regions that occupy a higher area ratio than the grid-shaped compressed region R805. The compressed region R806 is arranged in the side region R52, and constitutes a first high-pressure region HR1. The compressed regions R805 and R806 are arranged with the same width throughout the entire front-to-rear direction. The area ratio of the compressed regions in the crotch region R57, the front region R58, and the rear region R59 are the same, so the absorbent article according to Modification 3 does not have a second high-pressure region HR2.

[0072] Fig. 6(D) is a plan view of an absorbent core 50E according to Modification 4. The absorbent core 50E according to Modification 4 has a compressed region R807 in the crotch region R57 where compressed regions are arranged in a grid pattern, a compressed region R808 in the front region R58 where linear compressed regions are arranged, and a compressed region R809 in the rear region R59 where linear compressed regions are arranged. In the compressed regions R808 and R809, the linear compressed regions have a higher area ratio than in the grid-like compressed region R807. The compressed region R808 is arranged in the front region R58, and the compressed region R809 is arranged in the rear region R59, and they constitute a second high-pressure region HR2.

[0073] Fig. 6(E) is a plan view of an absorbent core 50F according to Modification 5. The absorbent core 50E according to Modification 5 has a compressed region R810 in which compressed portions are arranged in a lattice pattern, and a compressed region R811 in which linear compressed portions are arranged. In the compressed region R811, the linear compressed portions have a higher area ratio than in the lattice-patterned compressed region R810. The compressed region R811 is arranged in the front region R58 and the rear region R59, and constitutes the second high-pressure region HR2.
