Hereinafter, embodiments of the present invention will be described. The embodiments shown below are examples of embodiments of the present invention, and the technical scope of the present invention is not limited to the following embodiments.

<Embodiment>
In this embodiment, for a diaper and a pad (both are examples of "absorbent articles" in the present application), the front body is arranged to face the abdomen of the wearer and the back body is arranged to face the back. The direction connecting with is the longitudinal direction. An inseam placed in the wearer's inseam (opposed to the crotch) between these front bodies (one side in the longitudinal direction) and the back body (other side in the longitudinal direction) (center in the longitudinal direction). The part is located. In addition, when the diaper or pad is attached to the wearer (hereinafter abbreviated as "wearing state"), the side facing the wearer's skin (inside in the attached state) is the skin surface side, and the skin surface side. The opposite side (outside when worn) is the non-skin side. Further, the direction connecting the skin surface side and the non-skin surface side is the thickness direction, and the direction orthogonal to both the longitudinal direction and the thickness direction is the width direction. In addition, viewing from the thickness direction is defined as a plan view.

FIG. 1 is a perspective view of an absorbent article according to an embodiment. Further, FIG. 2 is a view of the absorbent article according to the embodiment as viewed from the skin surface side. The absorbent article 6 is used to absorb and retain a liquid such as urine. The absorbent article 6 can also be regarded as a pad described later or a part of a disposable diaper. As shown in FIG. 1, the absorbent article 6 has a length along the longitudinal direction and a lateral width along the width direction orthogonal to the longitudinal direction. The absorbent article 6 has a central region 6C including a virtual center line in the width direction of the absorbent article 6 and peripheral regions 6S provided on both left and right sides of the central region 6C. The absorbent article 6 is provided with a slit 61S extending in the longitudinal direction inside. The slit 61S is arranged in the portion of the central region 6C sandwiched from both the left and right sides by the peripheral region 6S. The slit 61S may be a groove or may be omitted.

As can be seen from FIG. 1, the central region 6C is lower than the peripheral region 6S. Further, as can be seen from FIG. 2, the peripheral region 6S is arranged at positions on both the left and right sides with a predetermined distance L1 from the virtual center line extending along the longitudinal direction of the absorbent article 6. Therefore, when the absorbent article 6 is attached to the wearer, the peripheral region 6S comes into contact with the wearer's skin. The central region 6C sandwiched by the peripheral regions 6S forms a space between the wearer's skin and the wearer's skin.

FIG. 3 is a diagram showing the internal structure of the absorbent article 6. The absorbent article 6 includes a mat 61, a liquid-permeable skin-side sheet 62 arranged on the skin surface side of the mat 61, and a liquid-impermeable non-skin surface arranged on the non-skin surface side of the mat 61. A side sheet 63 is provided.

The mat 61 is provided with water in the gaps between short fibers of cellulose-based fibers such as pulp fibers, rayon fibers, or cotton fibers, and short fibers obtained by hydrophilizing synthetic fibers such as polyethylene, polypropylene, or polyethylene terephthalate. It has a structure that retains granular absorbent resin such as SAP (Highly Absorbent Polymer), which is a hydrophilic polymer having a crosslinked structure that can be absorbed and retained. Since the mat 61 is a member forming the core of the absorbent article 6, it extends along the longitudinal direction of the absorbent article 6 between the skin surface side sheet 62 and the non-skin surface side sheet 63. Become. The mat 61 is provided with a central absorption portion 61C forming the central region 6C and peripheral absorption portions 61A and 61B forming the peripheral region 6S by bending along the longitudinal direction on both the left and right sides of the virtual center line. Part or all of the faces of the valley folds facing each other by bending are adhered to each other so that the bent portions do not return to their original positions. The peripheral absorption portions 61A and 61B are configured to overlap the central absorption portion 61C from the skin surface side at positions on both the left and right sides at a predetermined distance L1 from the virtual center line of the absorbent article 6. Therefore, in the absorbent article 6, the portion of the peripheral region 6S is higher than the portion of the central region 6C by the thickness of the peripheral absorbing portions 61A and 61B as compared with the portion of the central region 6C. The thickness of the mat 61 may be the same or different between the peripheral absorption portion 61A, the skin surface side sheet 62, and the non-skin surface side sheet 63.

Specifically, a woven fabric, a non-woven fabric, a porous film, or the like is used for the skin surface side sheet 62. As the non-woven fabric, a thermoplastic resin fiber such as polypropylene, polyethylene, polyester, or nylon that has been hydrophilized may be used, or an air-through non-woven fabric, a point bond non-woven fabric, a spunbond non-woven fabric, a melt blow non-woven fabric, or the like may be used. May be good. Further, as the non-skin surface side sheet 63, specifically, a liquid-impermeable film made of polyethylene resin is used. The non-skin surface side sheet 63 may be made of a microporous polyethylene film having a plurality of fine holes formed in order to obtain air permeability for preventing stuffiness in the mounted state while maintaining liquid impermeableness. good.

When the absorbent article 6 is used, for example, as a part of a component of a diaper or a pad described later, the skin surface side sheet 62 and the non-skin surface side sheet 63 are captured as a core wrap sheet wrapping the mat 61. You may. When the skin surface side sheet 62 and the non-skin surface side sheet 63 are regarded as core wrap sheets, the non-skin surface side sheet 63 may be a liquid permeable sheet.

In such an absorbent article 6, even if a load is applied to the exterior surface of the absorbent article 6 located on the non-skin surface side and the central absorbing portion 61C is pressed toward the skin surface side, the central absorbing portion 61C remains at the periphery. It is supported from the skin surface side by the absorption portions 61A and 61B. FIG. 4 is a diagram showing a state of support. For example, when the wearer wearing the absorbent article 6 sits on the chair, a load is applied to the exterior surface of the absorbent article 6 from the seat surface S of the chair, and the central absorbing portion 61C presses the wearer's skin surface side. Even so, the central absorption portion 61C is supported from the skin surface H side by the peripheral absorption portions 61A and 61B sandwiched between the central absorption portion 61C and the skin surface H of the wearer's buttocks. Therefore, in the portion of the central region 6C, the space between the central absorption portion 61C and the skin surface H of the wearer is maintained. Therefore, even when the central absorption portion 61C itself is compressed by the load and the effective area of the flow path of the slit 61S is lost and the function as the flow path is almost lost, the peripheral absorption portions 61A and 61B center the center. The space of the central region 6C maintained between the absorption portion 61C and the wearer maintains the function as a flow path. Therefore, the liquid discharged from the wearer can be diffused in the longitudinal direction of the absorbent article 6, and the liquid can be absorbed by the entire absorbent article 6.

Further, the mat 61 has a central absorption portion 61C forming a central region 6C and a peripheral region by bending along the longitudinal direction together with the skin surface side sheet 62 and the non-skin surface side sheet 63 on both the left and right sides of the virtual center line. Peripheral absorption portions 61A and 61B forming 6S are formed. Therefore, the mat 61 has a form in which a part of the non-skin surface side sheet 63 bent together with the mat 61 is sandwiched between the peripheral absorption portion 61A and the central absorption portion 61C. The folded portion has a Z-shaped cross-sectional view. The non-skin surface side sheet 63 is liquid impermeable as described above. Therefore, the liquid absorbed by the mat 61 does not easily flow between the peripheral absorption portion 61A and the central absorption portion 61C. Therefore, the non-skin surface side sheet 63 sandwiched between the peripheral absorption portion 61A and the central absorption portion 61C exerts the following effects.

FIG. 5 is a diagram showing an example of a liquid flow path in the mat 61. The liquid such as urine discharged from the wearer diffuses from the slit 61S to the left and right sides of the absorbent article 6 and is absorbed by the central absorption portion 61C. Since the skin surface side sheet 62 partially sandwiched between the central absorption portion 61C and the peripheral absorption portion 61B is a liquid permeable sheet, the liquid absorbed by the central absorption portion 61C is the skin surface side sheet 62. It can be diffused to the peripheral absorption portion 61B through. On the other hand, since the non-skin surface side sheet 63 sandwiched between the peripheral absorption portion 61A and the peripheral absorption portion 61B is a liquid impermeable sheet, the liquid absorbed by the peripheral absorption portion 61B is a non-skin surface. It cannot diffuse to the peripheral absorption portion 61A through the side sheet 63. Therefore, the liquid absorbed by the peripheral absorption unit 61B cannot diffuse to the peripheral absorption unit 61A unless it passes through the folded portion connecting the peripheral absorption unit 61A and the peripheral absorption unit 61B. Since the effective area of the folded portion as a flow path is narrow due to the folded portion, the liquid does not easily flow. Therefore, the peripheral absorption unit 61A can maintain a dry state before absorption for a relatively long time as compared with the peripheral absorption unit 61B and the central absorption unit 61C. Therefore, it is possible to suppress the possibility of the liquid absorbed by the absorbent article 6 coming into contact with the portion of the skin surface H facing the peripheral region 6S as much as possible. Further, also in the portion of the skin surface H facing the central region 6C, the central absorption portion 61C is supported from the skin surface H side by the peripheral absorption portions 61A and 61B, and the absorbent article 6 becomes the skin surface H in the central region 6C. Since it is difficult to come into contact with the skin surface H, the possibility that the liquid absorbed by the central absorbing portion 61C of the absorbent article 6 comes into contact with the skin surface H is suppressed as much as possible. Therefore, it can be said that the absorbent article 6 is a form of an epoch-making novel structure capable of suppressing the contact of the liquid with the skin as much as possible in the entire area of the portion substantially in contact with the skin surface H.

In order to effectively exert the support function of the peripheral absorption portions 61A and 61B, it is preferable that the peripheral absorption portions 61A and 61B have an appropriate thickness. In order to effectively secure the space in the central region 6C, it is preferable that the peripheral absorption portions 61A and 61B do not sink into the central absorption portion 61C by a load. Therefore, for example, at least one of the peripheral absorption portions 61A and the peripheral absorption portion 61B. It is conceivable to make the top thicker than the central absorption portion 61C. For example, if the peripheral absorption portion 61A is thicker than the central absorption portion 61C, even if a load is applied to the peripheral absorption portion 61A and the peripheral absorption portions 61A and 61B slightly sink into the central absorption portion 61C, the peripheral absorption portion 61A is in the center. It is possible to maintain a sufficient height to secure an effective space in the portion of the region 6C.

Further, in order to effectively exert the support function of the peripheral absorption portions 61A and 61B, it is preferable that the peripheral region 6S and the central region 6C have an appropriate width. The width of the peripheral region 6S depends on the age group of the wearer wearing the absorbent article 6, but is, for example, 10 to 100 mm, more preferably 20 to 50 mm, still more preferably 30 to 40 mm. If the peripheral region 6S has such a lateral width, the peripheral absorbing portions 61A and 61B can appropriately support the load applied to the absorbent article 6. The width of the central region 6C is, for example, 10 to 100 mm, more preferably 20 to 50 mm, still more preferably 30 to 40 mm, depending on the age group of the wearer wearing the absorbent article 6. If the central region 6C has such a lateral width, the peripheral absorbing portions 61A and 61B can appropriately support the load applied to the absorbent article 6.

Further, the peripheral absorption portion 61A and the peripheral absorption portion 61B are formed by bending the mat 61, and as described above, one of the surfaces of the valley fold portions facing each other by bending so that the bent portion does not return to the original position. Part or all are glued together. However, if the surfaces of the valley fold portions facing each other are made non-adhesive by bending, the restoring force of the bent portion between the peripheral absorption portion 61A and the peripheral absorption portion 61B can be obtained when the wearer is attached. Due to the restoring force of the bent portion between the peripheral absorption portion 61B and the central absorption portion 61C, a force for pressing the peripheral absorption portion 61A toward the skin surface side of the wearer is generated. Therefore, for example, when the peripheral region 6S is provided with a three-dimensional gather that rises toward the wearer's skin surface, the three-dimensional gather does not easily separate from the wearer's skin surface, and urine from the absorbent article 6 is provided. It is possible to effectively suppress leakage and the like.

By the way, the absorbent article 6 of the present embodiment may have the following internal structure. Hereinafter, a modified example of the internal structure of the absorbent article 6 will be illustrated.

<First modification>
FIG. 6 is a diagram showing a first modification of the internal structure of the absorbent article 6. In this first modification, the peripheral absorption portion 61A and the central absorption portion 61C are not connected and are separate bodies. That is, the peripheral absorption portion 61A and the central absorption portion 61C are not formed by folding back the mat 61, but are formed separately and sandwiched between the skin surface side sheet 62 and the non-skin surface side sheet 63. be. Therefore, in the first modification, there is no corresponding peripheral absorption portion 61B described above. Therefore, in FIG. 6, in order to facilitate understanding, the portion where the peripheral absorption portion 61B described above was present is hollow, but the cavity is actually collapsed.

Further, in the first modification, since there is no corresponding peripheral absorption portion 61B described above, the portion of the peripheral region 6S is lower by the thickness of the peripheral absorption portion 61B as compared with the above embodiment. .. However, even in the first modification, the peripheral region 6S is higher than the central region 6C by the thickness of the peripheral absorbing portion 61A. Therefore, also in the first modification, as in the above embodiment, even if a load is applied to the exterior surface of the absorbent article 6 located on the non-skin surface side and the central absorption portion 61C is pressed toward the skin surface side, the center The absorbing portion 61C is supported from the skin surface side by the peripheral absorbing portion 61A. Therefore, even if the wearer wearing the absorbent article 6 sits on the chair, the space between the central absorbent portion 61C and the wearer's skin surface H is maintained in the central region 6C. Therefore, even when the central absorption portion 61C itself is compressed by the load and the effective area of the flow path of the slit 61S is lost and the function as the flow path is almost lost, the central absorption portion 61A causes the central absorption portion. The space in the portion of the central region 6C maintained between the 61C and the wearer maintains its function as a flow path. Therefore, the liquid discharged from the wearer can be diffused in the longitudinal direction of the absorbent article 6, and the liquid can be absorbed by the entire absorbent article 6.

Further, also in the first modification, the absorbent article 6 has a skin surface side sheet 62 and a non-skin surface side sheet 63 sandwiching the peripheral absorption portion 61A and the central absorption portion 61C on both the left and right sides of the virtual center line. Is bent along the longitudinal direction of the absorbent article 6, so that a part of the bent non-skin surface side sheet 63 is sandwiched between the peripheral absorbing portion 61A and the central absorbing portion 61C. Therefore, the non-skin surface side sheet 63 sandwiched between the peripheral absorption portion 61A and the central absorption portion 61C is an absorbent article for the portion of the skin surface H facing the peripheral region 6S, as in the above embodiment. The possibility of contact with the liquid absorbed in 6 is suppressed as much as possible. Further, even in the portion of the skin surface H facing the central region 6C, the central absorption portion 61C is supported from the skin surface H side by the peripheral absorption portion 61A, and the central region 6C does not easily come into contact with the skin surface H, so that the absorption property is absorbable. The possibility that the absorbed liquid comes into contact with the central absorption portion 61C of the article 6 is suppressed as much as possible.

<Second modification>
FIG. 7 is a diagram showing a second modification of the internal structure of the absorbent article 6. In the above embodiment and the first modification, the inside of the absorbent article 6 is made of the mat 61, but the SAP sheet 65 may be used in addition to the mat 61. The SAP sheet is a sheet made of a fibrous material on which a SAP layer formed by containing particles of SAP which is a super absorbent polymer "hereinafter, also referred to as" SAP particles "" is supported. When the SAP layer is sandwiched between two sheets, both sheets are formed from a fibrous material. Then, at least for the sheet arranged on the skin surface side, a hydrophilic sheet is adopted. Examples of such a sheet include a non-woven fabric made of synthetic fibers such as polypropylene (PP) fiber and polyethylene terephthalate (PET) fiber. The "nonwoven fabric" can be, for example, a sheet or a web formed by adhering or entwining short fibers or filaments made of non-cellulose synthetic fibers. In order to make the sheet hydrophilic, a hydrophilic treatment such as coating, spraying, or impregnating the raw cotton of the non-woven fabric with a surfactant may be performed.

The SAP particles used in the SAP sheet 65 are granular SAPs, and for example, those capable of absorbing and retaining water having a weight of 5 times or more of its own weight can be adopted. Further, as the SAP, a starch-based, cellulose-based, synthetic resin-based, etc. SAP can be used. It may be a crosslinked product or one made of an acrylic acid (salt) polymer. Further, as for the particle shape of SAP, for example, a crushed type and a pearl type are known.

This second modification is the same as the first modification except that the peripheral absorption portion 61A of the first modification is replaced with the SAP sheet 65. Therefore, in the second modification, the portion of the peripheral region 6S is lower than that of the peripheral absorption portion 61A because the thickness of the SAP sheet 65 is thinner than that of the first modification. However, also in the second modification, the portion of the peripheral region 6S is higher than the portion of the central region 6C by the thickness of the SAP sheet 65. Therefore, in the second modification as well, as in the above embodiment and the first modification, a load is applied to the exterior surface of the absorbent article 6 located on the non-skin surface side, and the mat 61 is pressed toward the skin surface side. Also, the mat 61 is supported from the skin surface side by the SAP sheet 65. Therefore, even if the wearer wearing the absorbent article 6 sits on the chair, the space between the mat 61 and the wearer's skin surface H is maintained in the central region 6C. Therefore, even when the mat 61 itself is compressed by the load and the effective area of the flow path of the slit 61S is lost and the function as the flow path is almost lost, the SAP sheet 65 allows the mat 61 and the wearer to work together. The space of the portion of the central region 6C maintained between the two maintains the function as a flow path.

Further, in the absorbent article 6, on the left and right sides of the virtual center line, the skin surface side sheet 62 and the non-skin surface side sheet 63 sandwiching the SAP sheet 65 and the mat 61 are placed along the longitudinal direction of the absorbent article 6. By bending the sheet 63, a part of the folded non-skin surface side sheet 63 is sandwiched between the SAP sheet 65 and the mat 61. The non-skin surface side sheet 63 is liquid impermeable as described above. Therefore, the liquid absorbed by the mat 61 does not easily flow between the SAP sheet 65 and the mat 61. Therefore, the non-skin surface side sheet 63 sandwiched between the mat 61 and the SAP sheet 65 was absorbed by the mat 61 with respect to the portion of the skin surface H facing the peripheral region 6S, as in the above embodiment. The possibility of liquid contact is suppressed as much as possible. Further, also in the portion of the skin surface H facing the central region 6C, the mat 61 is supported from the skin surface H side by the SAP sheet 65, and the central region 6C does not easily come into contact with the skin surface H. The possibility of contact with the liquid absorbed by the mat 61 is suppressed as much as possible.

<Third modification example>
FIG. 8 is a diagram showing a third modification of the internal structure of the absorbent article 6. In the third modification, the skin surface side sheet 62 and the non-skin surface side sheet 63 are not folded back along the folded portion of the mat 61, and the mat 61 is folded back to the peripheral absorption portion 61A, the peripheral absorption portion 61B, and the center. The one in which the absorption portion 61C is formed is sandwiched between the skin surface side sheet 62 and the non-skin surface side sheet 63.

Also in the third modification, as in the above embodiment, even if a load is applied to the exterior surface of the absorbent article 6 located on the non-skin surface side and the central absorption portion 61C is pressed toward the skin surface side, the central absorption portion The 61C is supported from the skin surface side by the peripheral absorption portions 61A and 61B. Therefore, in the portion of the central region 6C, the space between the central absorption portion 61C and the skin surface H of the wearer is maintained. Therefore, even when the central absorption portion 61C itself is compressed by the load and the effective area of the flow path of the slit 61S is lost and the function as the flow path is almost lost, the peripheral absorption portions 61A and 61B center the center. The space of the central region 6C maintained between the absorption portion 61C and the wearer maintains the function as a flow path. Therefore, the liquid discharged from the wearer can be diffused in the longitudinal direction of the absorbent article 6, and the liquid can be absorbed by the entire absorbent article 6.

<Fourth modification>
FIG. 9 is a diagram showing a fourth modification of the internal structure of the absorbent article 6. This fourth modification is basically the same as the third modification, but the form of the skin surface side sheet 62 is slightly different. That is, in the third modification, the space of the central region 6C formed between the central absorption portion 61C and the skin surface H by the peripheral absorption portion 61A and the peripheral absorption portion 61B is the non-skin portion of the skin surface side sheet 62. It was formed on the surface side, in other words, inside the absorbent article 6. On the other hand, in the fourth modification, since the skin surface side sheet 62 is in close contact with each other along the shape of the mat 61, the peripheral absorption portion 61A and the peripheral absorption portion 61B allow the central absorption portion 61C and the skin to adhere to each other. The space of the portion of the central region 6C formed between the surface H and the surface H is formed on the skin surface side of the skin surface side sheet 62.

Therefore, in the fourth modification, when a load is applied to the exterior surface of the absorbent article 6 located on the non-skin surface side and the central absorption portion 61C is pressed toward the skin surface side, the central absorption portion 61C The space between the wearer's skin surface H and the skin surface H is maintained, and the space can function as a flow path, and can also function as a space for accommodating solids such as stool.

<Fifth variant>
FIG. 10 is a diagram showing a fifth modification of the internal structure of the absorbent article 6. In the fifth modification, the peripheral absorption portion 61A and the central absorption portion 61C are not connected and are separate bodies. Further, in the fifth modification, the skin surface side sheet 62 and the non-skin surface side sheet 63 are not sandwiched between the folded portions of the mat 61, and the peripheral absorption portion 61A and the central absorption portion 61C are overlapped with each other. Is sandwiched between the skin surface side sheet 62 and the non-skin surface side sheet 63.

Also in the fifth modification, as in the above embodiment and each modification, even if a load is applied to the exterior surface of the absorbent article 6 located on the non-skin surface side and the central absorption portion 61C is pressed toward the skin surface side. The central absorption portion 61C is supported from the skin surface side by the peripheral absorption portion 61A. Therefore, in the portion of the central region 6C, the space between the central absorption portion 61C and the skin surface H of the wearer is maintained. Therefore, even when the central absorption portion 61C itself is compressed by the load and the effective area of the flow path of the slit 61S is lost and the function as the flow path is almost lost, the central absorption portion 61A causes the central absorption portion. The space in the portion of the central region 6C maintained between the 61C and the wearer maintains its function as a flow path. Therefore, the liquid discharged from the wearer can be diffused in the longitudinal direction of the absorbent article 6, and the liquid can be absorbed by the entire absorbent article 6.

<Sixth modification>
FIG. 11 is a diagram showing a sixth modification of the internal structure of the absorbent article 6. The sixth modification is basically the same as the fifth modification, but the form of the skin surface side sheet 62 is slightly different. That is, in the fifth modification, the space of the central region 6C formed between the central absorption portion 61C and the skin surface H by the peripheral absorption portion 61A is the non-skin surface side of the skin surface side sheet 62, in other words. , Was formed inside the absorbent article 6. On the other hand, in the sixth modification, since the skin surface side sheet 62 is in close contact with each other along the shape of the mat 61, the peripheral absorption portion 61A betweens the central absorption portion 61C and the skin surface H. The space of the portion of the central region 6C formed in is formed on the skin surface side of the skin surface side sheet 62.

Therefore, in the sixth modification, when a load is applied to the exterior surface of the absorbent article 6 located on the non-skin surface side and the central absorption portion 61C is pressed toward the skin surface side, the central absorption portion 61C The space between the wearer's skin surface H and the skin surface H is maintained, and the space can function as a flow path, and can also function as a space for accommodating solids such as stool.

<7th modification>
FIG. 12 is a diagram showing a seventh modification of the internal structure of the absorbent article 6. The seventh modification has basically the same structure as the fifth modification, but is provided with the SAP sheet 65 instead of the peripheral absorption portion 61A.

Also in the seventh modification, as in the above embodiment and each modification, even if a load is applied to the exterior surface of the absorbent article 6 located on the non-skin surface side and the mat 61 is pressed toward the skin surface side, the mat 61 is supported from the skin surface side by the SAP sheet 65. Therefore, in the portion of the central region 6C, the space between the mat 61 and the wearer's skin surface H is maintained. Therefore, even when the mat 61 itself is compressed by the load and the effective area of the flow path of the slit 61S is lost and the function as the flow path is almost lost, the SAP sheet 65 allows the mat 61 and the wearer to work together. The space of the portion of the central region 6C maintained between the two maintains the function as a flow path. Therefore, the liquid discharged from the wearer can be diffused in the longitudinal direction of the absorbent article 6, and the liquid can be absorbed by the entire absorbent article 6.

<8th modification>
FIG. 13 is a diagram showing an eighth modification of the internal structure of the absorbent article 6. This eighth modification is the same as the above embodiment except that the SAP sheet 65 is added to the skin surface side of the peripheral absorption portion 61A in the above embodiment. Therefore, in the eighth modification, the peripheral region 6S is further increased by the thickness of the SAP sheet 65 as compared with the above embodiment. Therefore, in the eighth modification, when the central absorption portion 61C is pressed toward the skin surface side, the central absorption portion 61C is supported from the skin surface side by the peripheral absorption portion 61A, the peripheral absorption portion 61B, and the SAP sheet 65. .. Therefore, in the portion of the central region 6C, the space between the central absorption portion 61C and the skin surface H of the wearer is more reliably maintained than in the above embodiment. Therefore, even when the central absorption unit 61C itself is compressed by the load and the effective area of the flow path of the slit 61S is lost and the function as the flow path is almost lost, the peripheral absorption unit 61A and the peripheral absorption unit 61B are lost. And the space of the central region 6C maintained between the central absorption portion 61C and the wearer by the SAP sheet 65 maintains the function as a flow path. Therefore, the liquid discharged from the wearer can be diffused in the longitudinal direction of the absorbent article 6, and the liquid can be absorbed by the entire absorbent article 6.

Further, also in the eighth modification, the absorbent article 6 has a skin surface side sheet 62 and a non-skin surface side sheet 63 sandwiching the peripheral absorption portion 61A and the central absorption portion 61C on both the left and right sides of the virtual center line. Is bent along the longitudinal direction of the absorbent article 6, so that a part of the bent non-skin surface side sheet 63 is sandwiched between the peripheral absorbing portion 61A and the central absorbing portion 61C. Therefore, the non-skin surface side sheet 63 sandwiched between the peripheral absorption portion 61A and the central absorption portion 61C has the central absorption portion for the portion of the skin surface H facing the peripheral region 6S, as in the above embodiment. The possibility of contact with the liquid absorbed by 61C is suppressed as much as possible. Further, also in the portion of the skin surface H facing the central region 6C, the central absorption portion 61C is supported from the skin surface H side by the peripheral absorption portion 61A, the peripheral absorption portion 61B, and the SAP sheet 65, and the central region 6C is the skin surface. Since it is difficult to come into contact with H, the possibility that the liquid absorbed by the central absorbing portion 61C of the absorbent article 6 comes into contact is suppressed as much as possible.

The eighth modification is also effective when the mat 61 is desired to be thinned. When the peripheral absorption portion 61A and the peripheral absorption portion 61B are provided by folding back the mat 61, it is necessary to make the mat 61 itself thin to some extent so that the mat 61 can be bent. When the mat 61 is made thin, the absorption capacity of the mat 61 itself is lowered. In this respect, in the eighth modification in which the SAP sheet 65 is superposed on the peripheral absorption portion 61A, the absorption capacity of the peripheral absorption portion 61A composed of the thin mat 61 can be supplemented by the SAP sheet 65.

<Other variants>
Further, the internal structure of the absorbent article 6 can be made into an appropriate structure by further combining the above-described embodiments and modifications thereof. It is also possible to replace all the mats 61 with SAP sheets.

<First application example>
Hereinafter, a case where the absorbent article 6 of the above embodiment or each modification is applied to a diaper will be illustrated. In this first application example, the case of so-called tape-type diapers is illustrated, but the same can be applied to pants-type diapers and pads.

FIG. 14 is a perspective view of a diaper. The diaper 1 is located in the inseam area 1B, which is a part corresponding to the inseam area covering the wearer's pubic area in the worn state, and the front body area 1F, which is a part corresponding to the wearer's front body, located on the front side of the inseam area 1B. And the back body region 1R, which is located behind the inseam region 1B and corresponds to the back body of the wearer. Tapes 2L and 2R that can be attached to the front patch 2F provided on the non-skin surface side of the front body region 1F are provided on the left and right edges of the rear body region 1R. Therefore, in the diaper 1, when the front body area 1F is arranged on the ventral side of the wearer and the back body area 1R is arranged on the back side of the wearer, the tapes 2L and 2R are attached to the front patch 2F. , It is fixed to the wearer's body in a state surrounding the wearer's abdomen and thigh. Since the diaper 1 is fixed to the wearer's body in such a form, the wearer can walk while wearing the diaper 1.

In the diaper 1, an absorber capable of absorbing and holding the liquid is mainly arranged in the vicinity of the inseam region 1B. The absorber that absorbs and retains the liquid is sandwiched between the back sheet 5 that forms the exterior surface of the diaper 1 and the top sheet 7 that forms the skin contact surface inside the diaper 1. It is provided inside. In addition, in order to prevent the formation of a gap that serves as a liquid outflow route between the diaper 1 and the wearer's skin, the diaper 1 has three-dimensional gathers 3BL, 3BR at the portion surrounding the wearer's thigh. Is provided, and a waist gather 3R is provided at a portion surrounding the wearer's abdominal circumference. The three-dimensional gathers 3BL, 3BR and the waist gathers 3R are in close contact with the wearer's skin due to the elastic force of the rubber thread. Therefore, the liquid excreted from the wearer's genital area is absorbed by the diaper 1 absorber with almost no leakage from the diaper 1.

When the absorbent article 6 of the above embodiment or each modification is applied to the diaper 1 in such a form, the skin surface side sheet 62 corresponds to the top sheet 7, and the non-skin surface side sheet 63 corresponds to the back sheet 5. Correspondingly, the mat 61 corresponds to an absorber provided between the top sheet 7 and the back sheet 5. When the absorbent article 6 is applied to such a diaper 1, a folded portion provided in the absorbent article 6 may be formed in the front body region 1F and the back body region 1R, but when worn, the front patch 2F of the tapes 2L and 2R may be formed. By sticking to, the folded portion is pulled and spreads as shown in FIG. However, if the folded state of the folded portion is maintained in or near the inseam region 1B, the support function by the peripheral absorbing portion 61A or the like when the wearer sits on a chair or the like is exhibited as described in the above embodiment. Will be done.

<Second application example>
Hereinafter, a case where the absorbent article 6 of the above embodiment or each modification is applied to the pad will be illustrated. FIG. 15 is a perspective view of the pad. The pad 11 is used for absorbing and holding a liquid such as urine, and can be used alone or stacked on the inside of a disposable diaper such as a diaper 1. The pad 11 is divided into an inseam region 15 that covers the wearer's pubic area, a front body region 14 located on the abdomen side of the wearer, and a back body region 16 located on the back side of the wearer when viewed in the longitudinal direction. Will be done. In addition, in FIG. 15, the pad 11 has the narrowest lateral width in the inseam region 15, and the inseam region 15 has a constricted gourd shape. However, the pad 11 is not limited to such a form, and may have a non-gourd shape having no constriction, for example, a substantially rectangular shape.

As shown in FIG. 15, the pad 11 includes a top sheet 12 arranged on the skin facing surface side in the mounted state. The top sheet 12 is a portion (skin facing surface) in contact with the wearer's skin when the pad 11 is attached, and is made of a liquid-permeable material that allows liquid such as urine to pass through. Further, the pad 11 includes a back seat 13 arranged on the opposite side of the skin facing surface in the mounted state. The back sheet 13 is a portion of the entire pad 11 that is a non-skin facing surface (outer surface) opposite to the skin facing surface, and is made of a liquid-impermeable material that does not allow liquids such as urine to permeate. The peripheral portions of the top sheet 12 and the back sheet 13 are joined to each other. Further, an absorber that absorbs a liquid such as urine is arranged between the top sheet 12 and the back sheet 13.

The pad 11 is provided with an absorber capable of absorbing and holding a liquid. The absorber that absorbs and retains the liquid is sandwiched between the back sheet 13 that forms the exterior surface of the pad 11 and the top sheet 12 that forms the skin contact surface inside the pad 11. It is provided inside. Therefore, the liquid excreted from the wearer's genital area is absorbed by the absorber in the pad 11 through the top sheet 12.

When the absorbent article 6 of the above embodiment or each modification is applied to the pad 11 of such a form, the skin surface side sheet 62 corresponds to the top sheet 12, and the non-skin surface side sheet 63 becomes the back sheet 13. Correspondingly, the mat 61 corresponds to the absorber provided between the top sheet 12 and the back sheet 13. Even if the absorbent article 6 is applied to the pad 11 in such a form, when the wearer sits on a chair or the like, the support function by the peripheral absorbing portion 61A or the like is exhibited as described in the above embodiment.

The functions exhibited when the absorbent article 6 of the embodiment or the modification is applied to the diaper 1, the pad 11, or the like will be described below.

<Slit alternative function>
FIG. 16 is a diagram showing how the inseam region 1B is pushed from both the left and right sides by the wearer's lower limbs when the diaper 1 is worn. When the diaper 1 is attached to the wearer, the portion of the inseam region 1B of the diaper 1 is sandwiched between the wearer's lower limbs from both the left and right sides. Therefore, as shown in FIG. 16, the inseam region 1B of the diaper 1 is sandwiched from both the left and right sides and collapsed. The same applies to the pad 11 and the pants-type diaper. Therefore, when the absorbent article 6 is applied to the diaper 1, the absorbent article 6 becomes as follows.

FIG. 17 is a first diagram illustrating how the slit 61S is closed. When the diaper 1 or the pad 11 to which the absorbent article 6 is applied is attached to the wearer, the absorbent article 6 is sandwiched between the wearer's lower limbs from both the left and right sides. Therefore, as shown in FIG. 17, the absorbent article 6 is in a state of being narrowed from both the left and right sides toward the virtual center line in the longitudinal direction. Therefore, the effective area of the slit 61S provided in the central absorption portion 61C as a flow path is smaller than that before mounting. However, a predetermined distance L2 is secured between the end of the peripheral region 6S on the central region 6C side in the width direction and the end of the slit 61S on the peripheral region 6S side in the width direction, and the width direction If the end portion of the peripheral region 6S on the peripheral region 6S side in the width direction is arranged inside the central region 6C side of the peripheral region 6S in the width direction, it is a case where the slit 61S is closed. However, in the portion of the central region 6C, a space having a width of at least (L2 × 2) shown by a broken line in FIG. 17 is secured. Therefore, the absorbent article 6 is narrowed from both the left and right sides toward the virtual center line in the longitudinal direction, and even when the slit 61S is closed, the space secured in the central region 6C is provided. Instead of the slit 61S, it becomes a flow path through which the liquid flows. Therefore, the liquid such as urine discharged from the wearer diffuses in the longitudinal direction of the absorbent article 6 through the space of the central region 6C, and the liquid can be absorbed by the entire absorbent article 6. It should be noted that such an effect is similarly exhibited when the SAP contained in the vicinity of the slit 61S of the central absorption portion 61C swells due to water absorption and the swelled SAP closes the slit 61S.

Further, since the slit 61S has a form that penetrates the central absorption portion 61C, the actual dimensions of the slit 61S are designed at the edge portion of the slit 61S due to the shape loss of the material constituting the central absorption portion 61C. May be narrower than. In this respect, the peripheral absorption portion 61A and the peripheral absorption portion 61B that form a space in the central region 6C have a form in which the portion facing the space is covered with the skin surface side sheet 62, so that the peripheral absorption portion 61A Even if the material constituting the peripheral absorption portion 61B loses its shape, it is unlikely that the portion of the central region 6C is narrowed due to the shape loss. Therefore, the shape of the space formed in the portion of the central region 6C is more reliably maintained than that of the slit 61S.

<Slit holding function>

FIG. 18 is a second diagram illustrating how the slit 61S is closed. In FIG. 18, the slit 61S is wider than in FIG. For example, as shown in FIG. 18, a predetermined distance L3 is secured between the end portion of the peripheral region 6S on the central region 6C side in the width direction and the end portion of the slit 61S on the peripheral region 6S side in the width direction. If the end portion of the slit 61S on the peripheral region 6S side in the width direction is arranged outside the end portion on the central region 6C side of the peripheral region 6S in the width direction, the central region 6C is tentatively arranged. Even when the space of the portion is closed, the width of at least (L3 × 2) is secured in the portion of the slit 61S. Therefore, even when the absorbent article 6 is narrowed from both the left and right sides toward the virtual center line in the longitudinal direction and the space of the central region 6C is closed, the slit 61S allows the liquid to flow. It does not lose its function as a flow path. Therefore, the liquid such as urine discharged from the wearer diffuses in the longitudinal direction of the absorbent article 6 through the slit 61S, and the liquid can be absorbed by the entire absorbent article 6. The liquid flowing through the slit 61S in a state where the space of the central region 6C is closed is hidden from the skin surface side of the absorbent article 6 in the slit 61.
Since it flows through S, it can be regarded as underground water. The liquid flowing through the slit 61S in a state like underground water does not easily adhere to the wearer's skin. Therefore, with such a form, it is possible to suppress the possibility that a liquid such as urine adheres to the wearer's skin as much as possible.

<Male genital support function>
FIG. 19 is a diagram showing sites corresponding to the urinary meatus and the anus. When the absorbent article 6 has a length (for example, about 56 cm) reaching from the wearer's front body through the inseam region to the back body, for example, the central region of the absorbent article 6 is shown in FIG. In 6C, the urinary meatus facing region R1 and the anus facing region R2 are aligned along the longitudinal direction of the absorbent article 6. The wearer's urinary meatus is located slightly anterior to the wearer's inseam. Therefore, the urinary meatus facing region R1 is located slightly on the front body side of the center of the absorbent article 6 in the longitudinal direction. Also, the wearer's anus is located slightly behind the wearer's inseam. Therefore, the anus facing region R2 is located slightly on the back body side of the center of the absorbent article 6 in the longitudinal direction.

Then, when urine is discharged from the urinary meatus of the wearer, the urine flows from the urethral meatus facing region R1 through the slit 61S and the like, diffuses into each part of the absorbent article 6, and is absorbed by the mat 61 and the SAP sheet 65. To. Further, when the stool is discharged from the wearer's anus, the stool adheres to the vicinity of the anus facing region R2 in the central region 6C.

Then, when the male wears the absorbent article 6, the male genitalia are held in the space of the central region 6C. FIG. 20 is a diagram showing how the male genitalia are supported. FIG. 20 illustrates a cross section of the absorbent article 6 of the above-described embodiment when the absorbent article 6 is cut by the reference numerals CC shown in FIG. However, the present invention is not limited to the absorbent article 6 of the embodiment, and the same applies to any of the above-described modifications.

When the central absorption portion 61C is mounted at a position covering the male genitalia D of the male wearer, the skin surface of the central absorption portion 61C is located on both the left and right sides at a predetermined distance L1 from the virtual center line of the absorbent article 6. The peripheral absorbing portions 61A and 61B overlapping from the side can support the male genitalia D covered by the central absorbing portion 61C from both sides in the width direction of the absorbent article 6. Therefore, the male genitalia D is held along the virtual center line of the absorbent article 6. Therefore, the possibility that the tip of the male genitalia D having the urinary meatus deviates from the virtual center line of the absorbent article 6 to the left or right is suppressed. If the tip of the male genitalia D is held along the virtual center line of the absorbent article 6, when urine is discharged from the urinary meatus at the tip of the male genitalia D, the urine is in the virtual center line of the absorbent article 6. It spreads almost evenly on both the left and right sides. Therefore, the possibility that urine leaks from the absorbent article 6 can be suppressed as much as possible as compared with the absorbent article in which the male genitalia D is not supported from both sides in the width direction.

In order to effectively exert the support function of the male genitalia D, the width of the central region 6C, in other words, the length of (L1 × 2) is assumed to be worn at least in the vicinity of the urinary meatus facing region R1. It is preferable to set it in consideration of the standard thickness of male genitalia. If the width of the central region 6C is excessive, the male genitalia D will not be supported by the peripheral absorption portions 61A and 61B. Further, if the width of the central region 6C is too small, the male genitalia D will not fit in the portion of the central region 6C, and the male genitalia D will not be supported by the peripheral absorption portions 61A and 61B. Therefore, the width of the central region 6C at least in the vicinity of the urinary meatus facing region R1 is, for example, in the range of 10 to 80 mm, more preferably in the range of 20 to 70 mm, and further preferably in the range of 30 to 60 mm.

Further, in order to effectively exert the support function of the male genitalia D, the height difference between the central region 6C and the peripheral region 6S is such that the male male is expected to be worn at least in the vicinity of the urinary meatus facing region R1. It is preferable to set it in consideration of the standard thickness of the vessel. This is because if the width of the central region 6C is too small, the supporting force from the left and right sides of the peripheral absorption portions 61A and 61B with respect to the male genitalia D is significantly lost. Therefore, the height difference at least in the vicinity of the urinary meatus facing region R1 is, for example, in the range of 2 to 30 mm, more preferably in the range of 5 to 25 mm, and further preferably in the range of 10 to 20 mm.

The absorbent article 6 may be worn with the tip of the male genitalia D facing toward the inseam of the wearer, or with the tip of the male genitalia D facing toward the front body of the wearer. Although it may be worn, the former wearing state is preferable from the viewpoint of absorbing urine by the entire absorbent article 6.

<Stool storage function>
FIG. 21 is a diagram showing how stool is stored. FIG. 21 illustrates a cross section of the absorbent article 6 of the above-described embodiment when the absorbent article 6 is cut by the reference numerals DD shown in FIG. However, the present invention is not limited to the absorbent article 6 of the embodiment, and the same applies to any of the above-described modifications.

When the central absorption portion 61C is attached to a position covering the wearer's anus, it overlaps the central absorption portion 61C from the skin surface side at positions on both the left and right sides at a predetermined distance L1 from the virtual center line of the absorbent article 6. The peripheral absorption portions 61A and 61B form a wall portion of a storage portion capable of storing the stool B between the central absorption portion 61C and the wearer's anus. Therefore, the stool discharged from the wearer's anus is discharged to the storage portion (space in the central region 6C) where the wall portion is formed by the peripheral absorption portions 61A and 61B and the bottom surface is formed by the central absorption portion 61C. become. Therefore, it is possible to suppress the possibility of stool leaking from the absorbent article 6 as much as possible, as compared with the absorbent article in which such a storage portion is not formed.

In order to effectively exert the storage function of stool B, the width of the central region 6C, in other words, the length of (L1 × 2), is the standard of the assumed wearer, at least in the vicinity of the anal facing region R2. It is preferable to set it in consideration of the amount of defecation. This is because if the width of the central region 6C is too small, the stool B will not fit in the portion of the central region 6C. Therefore, the width of the central region 6C at least in the vicinity of the anus facing region R2 is, for example, 10 mm or more, more preferably 20 mm or more, still more preferably 30 mm or more.

Further, in order to effectively exert the storage function of the stool B, the height difference between the central region 6C and the peripheral region 6S is assumed to be the standard defecation of the wearer, at least in the vicinity of the anal facing region R2. It is preferable to set it in consideration of the amount. This is because if the width of the central region 6C is too small, the stool B will not fit in the portion of the central region 6C. Therefore, the height difference at least in the vicinity of the anus facing region R2 is, for example, 2 mm or more, more preferably 5 mm or more, still more preferably 10 mm or more. However, even if the stool does not completely fit in the storage section, the storage section can exert the function of holding the stool. Therefore, the absorbent article 6 is designed so that the storage section is sized to completely fit the stool. You don't have to.

As described above, the various functions of the above-described embodiment and each modification have been described, but the absorbent article 6 is not limited to those exhibiting only such functions. The absorbent article 6 can also exhibit, for example, a function of alleviating an external impact transmitted to the wearer's buttocks, a function of keeping the wearer's buttocks warm, and various other functions.

<Manufacturing equipment>
FIG. 22 is a diagram showing an example of an apparatus for manufacturing the absorbent article 6. The absorbent article 6 is bent, for example, when an unfolded flat long intermediate product C is continuously fed, the left and right sides of the intermediate product C in the width direction are bent in a Z-shape in a cross-sectional view and discharged. It can be manufactured by the manufacturing apparatus M having a built-in mechanism. The bending mechanism in the manufacturing apparatus M is, for example,
The first roller that gradually raises both the left and right sides of the intermediate product C in the width direction and the rising portion of the intermediate product C that has been raised by the first roller are the portions of the predetermined first distance from the left and right ends of the intermediate product C in the width direction. The first sailor that is bent so as to wrap it toward the center in the width direction, the second roller that gradually raises both the left and right sides of the intermediate product C in the width direction, and the rising portion of the intermediate product C that is raised by the second roller. It can be composed of a second sailor or the like that bends outward in the width direction at a predetermined second distance shorter than the predetermined first distance from the left and right ends of the intermediate product C in the width direction.

In the case of the manufacturing apparatus M having such a bending mechanism built-in, for example, an intermediate product C in which the mat 61 is simply sandwiched between the skin surface side sheet 62 and the non-skin surface side sheet 63 is prepared, and the intermediate product C is prepared. It is possible to continuously manufacture the absorbent article 6 simply by sending the product to the manufacturing apparatus M.
