Summary of the Invention

Problems to be Solved by the Invention

[0004] The male genital organ can be directed in various directions at the tip. Therefore, when the tip of the male genital organ deviates from the center in the width direction of the absorbent article and faces either the left or the right, urine discharged from the tip of the male genital organ may leak out of the absorbent article.

[0005] Therefore, an object of the present invention is to provide an absorbent article that can suppress the possibility of urine leakage as much as possible.

Means for Solving the Problems

[0006] In order to solve the above problems, in the present invention, in addition to the first absorption part that can cover the male genital organ, a second absorption part that can support the male genital organ from both sides in the width direction is overlapped on the skin surface side of the first absorption part.

[0007] Specifically, the present invention relates to an absorbent article having a length along the longitudinal direction and a width along the width direction orthogonal to the longitudinal direction, comprising an absorber extending along the longitudinal direction, a liquid-permeable skin-side sheet disposed on the skin side of the absorber, and a liquid-impermeable non-skin-side sheet disposed on the non-skin side of the absorber. The absorber forms a region including the virtual center line in the width direction of the absorbent article, and has a first absorption portion capable of covering at least the male genitalia of the wearer, and a second absorption portion that overlaps the first absorption portion from the skin side at positions on both left and right sides at a predetermined distance from the virtual center line and can support the male genitalia covered by the first absorption portion from both sides in the width direction.

[0008] Note that the absorber may be provided in a portion sandwiched from both left and right sides by the second absorption portion of the first absorption portion, and may further have a flow path formed by a groove or slit extending along the longitudinal direction.

[0009] Further, the absorber may form the first absorption portion and the second absorption portion by being bent along the longitudinal direction on both left and right sides of the virtual center line.

[0010] Further, a part of the non-skin-side sheet bent together with the absorber may be sandwiched between the first absorption portion and the second absorption portion.

[0011] Further, the first absorption portion and the second absorption portion may be formed of absorbent materials separate from each other.

[0012] Further, the absorber may sandwich a part of the non-skin-side sheet between the first absorption portion and the second absorption portion.

Advantages of the Invention

[0013] With the above absorbent article, the possibility of urine leakage can be suppressed as much as possible.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, embodiments of the present invention will be described. The embodiments shown below are examples of embodiments of the present invention, and do not limit the technical scope of the present invention to the following aspects.

[0016] <Embodiment> In the present embodiment, for a diaper and a pad (both are examples of the "absorbent article" as used in the present application), the direction connecting the front body portion disposed facing the abdomen of the wearer and the back body portion disposed facing the back is defined as the longitudinal direction. Between these front body portions (one side in the longitudinal direction) and the back body portions (the other side in the longitudinal direction) (the center in the longitudinal direction), there is a crotch portion disposed under the crotch of the wearer (opposite to the crotch). Further, in a state where the diaper or pad is worn on the wearer (hereinafter abbreviated as the "worn state"), the side facing the skin of the wearer (the inner side in the worn state) is defined as the skin side, and the opposite side of the skin side (the outer side in the worn state) is defined as the non-skin side. Furthermore, the direction connecting the skin side and the non-skin side is defined as the thickness direction, and the direction orthogonal to both the longitudinal direction and the thickness direction is defined as the width direction. In addition, viewing from the thickness direction is defined as a plan view.

[0017] FIG. 1 is a perspective view of an absorbent article according to an embodiment. FIG. 2 is a view of the absorbent article according to the embodiment seen from the skin side. The absorbent article 6 is used to absorb and hold liquids such as urine. The absorbent article 6 can 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 It has a lateral width along the width direction orthogonal to the longitudinal direction. The absorbent article 6 has a central region 6C including the virtual center line in the width direction of the absorbent article 6, and peripheral regions 6S provided on both the left and right sides of the central region 6C. In the absorbent article 6, a slit 61S extending along the longitudinal direction is provided inside. This slit 61S is disposed in a portion of the central region 6C sandwiched from both the left and right sides by the peripheral regions 6S. Note that the slit 61S may be a groove or may be omitted.

[0018] As can be seen from FIG. 1, the central region 6C is lower than the peripheral region 6S. Also, as can be seen from FIG. 2, the peripheral regions 6S are disposed at positions on both the left and right sides at 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 worn by the wearer, the peripheral regions 6S come into contact with the wearer's skin. And the central region 6C sandwiched by the peripheral regions 6S forms a space between it and the wearer's skin.

[0019] FIG. 3 is a view showing the internal structure of the absorbent article 6. The absorbent article 6 includes a mat 61, a liquid-permeable skin-side sheet 62 disposed on the skin side of the mat 61, and a liquid-impermeable non-skin-side sheet 63 disposed on the non-skin side of the mat 61.

[0020] The mat 61 has a structure in which granular absorbent resins such as SAP (Super Absorbent Polymer), which is a hydrophilic polymer having a crosslinked structure capable of absorbing and retaining water, are held in the gaps between short fibers of cellulosic fibers such as pulp fibers, rayon fibers, or cotton fibers, and short fibers obtained by subjecting synthetic fibers such as polyethylene, polypropylene, or polyethylene terephthalate to a hydrophilic treatment. And since the mat 61 is a member that forms the core of the absorbent article 6, it will extend along the longitudinal direction of the absorbent article 6 between the skin-side sheet 62 and the non-skin-side sheet 63. The mat 61 is provided with a central absorbent portion 61C that forms a central region 6C and peripheral absorbent portions 61A and 61B that form a peripheral region 6S by being bent along the longitudinal direction on both the left and right sides of the virtual center line. The surfaces of the valley-folded portions facing each other by the folding are partially or entirely adhered to each other so that the folded portion does not return to its original state. The peripheral absorbent portions 61A and 61B are configured to overlap the central absorbent portion 61C from the skin 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. For this reason, in the absorbent article 6, the portion of the peripheral region 6S is higher than the central region 6C by the thickness of the peripheral absorbent portions 61A and 61B compared to the portion of the central region 6C. Note that the mat 61 may have the same thickness or different thicknesses among the portion of the peripheral absorbent portion 61A, the portion of the skin-side sheet 62, and the portion of the non-skin-side sheet 63.

[0021] Specifically, a woven fabric, a non-woven fabric, a porous film, etc. are used for the skin-side sheet 62. Note that as the non-woven fabric, those obtained by subjecting fibers of thermoplastic resins such as polypropylene, polyethylene, polyester, and nylon to a hydrophilic treatment may be used, or an air-through non-woven fabric, a point-bond non-woven fabric, a spunbond non-woven fabric, a meltblown non-woven fabric, etc. may be used. Also, specifically, a liquid-impermeable film formed of a polyethylene resin is used for the non-skin-side sheet 63. A microporous polyethylene film having a plurality of fine pores may be used for the non-skin-side sheet 63 in order to obtain air permeability for preventing stuffiness in the wearing state while maintaining liquid impermeability.

[0022] In addition, when the absorbent article 6 is used, for example, as a part of a constituent member of a diaper or a pad described later, the skin-side sheet 62 and the non-skin-side sheet 63 may be regarded as a core wrap sheet that wraps the mat 61. When the skin-side sheet 62 and the non-skin-side sheet 63 are regarded as a core wrap sheet, the non-skin-side sheet 63 may be a liquid-permeable sheet.

[0023] In such an absorbent article 6, even when a load is applied to the outer surface located on the non-skin side of the absorbent article 6 and the central absorbent portion 61C is pressed toward the skin side, the central absorbent portion 61C is supported from the skin side by the peripheral absorbent portions 61A and 61B. FIG. 4 is a diagram showing the state of support. For example, when a wearer wearing the absorbent article 6 sits on a chair, a load is applied to the outer surface of the absorbent article 6 from the seat surface S of the chair, and even when the central absorbent portion 61C is pressed toward the skin side of the wearer, the central absorbent portion 61C is supported from the skin H side by the peripheral absorbent portions 61A and 61B sandwiched between the central absorbent portion 61C and the skin H of the wearer's buttocks. For this reason, in the portion of the central region 6C, the space between the central absorbent portion 61C and the skin H of the wearer is maintained. For this reason, even when the central absorbent 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 a flow path is almost lost, the space in the portion of the central region 6C maintained between the central absorbent portion 61C and the wearer by the peripheral absorbent portions 61A and 61B retains the function as a flow path. For this reason, 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.

[0024] Further, the mat 61 forms a central absorption portion 61C that forms a central region 6C and peripheral absorption portions 61A and 61B that form a peripheral region 6S by being bent along the longitudinal direction together with the skin-side sheet 62 and the non-skin-side sheet 63 on both the left and right sides of the virtual center line. Therefore, the mat 61 has a form in which a part of the non-skin-side sheet 63 bent together with the mat 61 is sandwiched between the peripheral absorption portion 61A and the central absorption portion 61C. And the folded-back portion exhibits a Z-shaped cross-sectional form. This non-skin-side sheet 63 is liquid-impermeable as described above. For this reason, the liquid absorbed by the mat 61 does not easily flow between the peripheral absorption portion 61A and the central absorption portion 61C. For this reason, the non-skin-side sheet 63 sandwiched between the peripheral absorption portion 61A and the central absorption portion 61C exhibits the following effects.

[0025] FIG. 5 is a diagram showing an example of the liquid flow path in the mat 61. The liquid such as urine discharged from the wearer diffuses from the slit 61S to both left and right sides of the absorbent article 6 and is absorbed by the central absorbent portion 61C. Since the skin-side sheet 62 partially sandwiched between the central absorbent portion 61C and the peripheral absorbent portion 61B is a liquid-permeable sheet, the liquid absorbed by the central absorbent portion 61C can diffuse to the peripheral absorbent portion 61B through the skin-side sheet 62. On the other hand, since the non-skin-side sheet 63 sandwiched between the peripheral absorbent portion 61A and the peripheral absorbent portion 61B is a liquid-impermeable sheet, the liquid absorbed by the peripheral absorbent portion 61B cannot diffuse to the peripheral absorbent portion 61A through the non-skin-side sheet 63. Therefore, the liquid absorbed by the peripheral absorbent portion 61B cannot diffuse to the peripheral absorbent portion 61A unless it passes through the folded-back portion connecting the peripheral absorbent portion 61A and the peripheral absorbent portion 61B. Since the effective area as a flow path is narrow due to the folding of the folded-back portion, the liquid does not flow easily. For this reason, the peripheral absorbent portion 61A can maintain a relatively dry state before absorption for a relatively long time compared to the peripheral absorbent portion 61B and the central absorbent portion 61C. Therefore, it is possible to suppress as much as possible the possibility that the liquid absorbed by the absorbent article 6 comes into contact with the portion of the skin surface H facing the peripheral region 6S. Also, in the portion of the skin surface H facing the central region 6C, since the central absorbent portion 61C is supported from the skin surface H side by the peripheral absorbent portions 61A and 61B and the absorbent article 6 is less likely to come into contact with the skin surface H in the central region 6C, the possibility that the liquid absorbed by the central absorbent 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 has a novel structure that can suppress contact of liquid with the skin as much as possible over the entire area of the portion substantially in contact with the skin surface H.

[0026] In order to effectively exert the supporting 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, since it is preferable that the peripheral absorption portions 61A and 61B do not sink into the central absorption portion 61C under the load, for example, it is conceivable to make at least one of the peripheral absorption portion 61A and the peripheral absorption portion 61B 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 sink somewhat into the central absorption portion 61C, the peripheral absorption portion 61A can maintain a sufficient height to secure an effective space in the portion of the central region 6 C.

[0027] Also, in order to effectively exert the supporting 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. For example, it is 10 to 100 mm, more preferably 20 to 50 mm, and still more preferably 30 to 40 mm. If the peripheral region 6S has such a width, the peripheral absorption portions 61A and 61B can appropriately support the load applied to the absorbent article 6. Also, the width of the central region 6C depends on the age group of the wearer wearing the absorbent article 6. For example, it is 10 to 100 mm, more preferably 20 to 50 mm, and still more preferably 30 to 40 mm. If the central region 6C has such a width, the peripheral absorption portions 61A and 61B can appropriately support the load applied to the absorbent article 6.

[0028] Further, the peripheral absorption portions 61A and 61B are formed by bending the mat 61. As described above, in order to prevent the bent portion from returning to its original state, a part or all of the surfaces of the opposing valley-folded portions are adhered to each other by bending. However, if the surfaces of the opposing valley-folded portions are not adhered to each other by bending, in the state where the absorbent article 6 is worn by the wearer, the restoring force of the bent portion between the peripheral absorption portion 61A and the peripheral absorption portion 61B and the restoring force of the bent portion between the peripheral absorption portion 61B and the central absorption portion 61C generate a force that presses the peripheral absorption portion 61A toward the skin surface side of the wearer. Therefore, for example, when a three-dimensional gather that rises toward the skin surface side of the wearer is provided in the peripheral region 6S, the three-dimensional gather does not easily separate from the skin surface of the wearer, and it is possible to effectively suppress urine leakage and the like from the absorbent article 6.

[0029] Incidentally, 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 exemplified.

[0030] <First Modified Example> FIG. 6 is a view showing a first modified example of the internal structure of the absorbent article 6. In this first modified example, the peripheral absorption portion 61A and the central absorption portion 61C are not connected and are separate. 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. Therefore, in this first modified example, there is no corresponding part to the peripheral absorption portion 61B described above. Therefore, in FIG. 6, for easy understanding, the portion where the peripheral absorption portion 61B described above existed is hollow, but actually the hollow is in a collapsed state.

[0031] Further, in this first modified example, since there is no corresponding part to the peripheral absorption part 61B described above, the part of the peripheral region 6S is lower by the thickness of the peripheral absorption part 61B compared to the above-described embodiment. However, also in this first modified example, the part of the peripheral region 6S is higher by the thickness of the peripheral absorption part 61A compared to the part of the central region 6C. Therefore, also in this first modified example, as in the above-described embodiment, even when a load is applied to the outer surface located on the non-skin side of the absorbent article 6 and the central absorption part 61C is pressed toward the skin side, the central absorption part 61C is supported from the skin side by the peripheral absorption part 61A. For this reason, even when the wearer wearing the absorbent article 6 sits on a chair, in the part of the central region 6C, the space between the central absorption part 61C and the wearer's skin surface H is maintained. For this reason, even when the central absorption part 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 a flow path is almost lost, the space of the part of the central region 6C maintained between the central absorption part 61C and the wearer by the peripheral absorption part 61A maintains the function as a flow path. For this reason, 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.

[0032] Also, in this first modified example, the absorbent article 6 is folded along the longitudinal direction of the absorbent article 6 with the skin-side sheet 62 and the non-skin-side sheet 63 sandwiching the peripheral absorption part 61A and the central absorption part 61C on both the left and right sides of the virtual center line, so that a part of the folded non-skin-side sheet 63 is sandwiched between the peripheral absorption part 61A and the central absorption part 61C. For this reason, the non-skin-side sheet 63 sandwiched between the peripheral absorption part 61A and the central absorption part 61C suppresses as much as possible the possibility that the liquid absorbed by the absorbent article 6 comes into contact with the part of the skin surface H facing the peripheral region 6S, as in the above-described embodiment. Also, in the part of the skin surface H facing the central region 6C, since the central absorption part 61C is supported from the skin surface H side by the peripheral absorption part 61A and the central region 6C is less likely to come into contact with the skin surface H, the possibility that the liquid absorbed by the central absorption part 61C of the absorbent article 6 comes into contact is suppressed as much as possible.

[0033] <Second Modified Example> FIG. 7 is a diagram showing a second modification of the internal structure of the absorbent article 6. In the above-described embodiment and the first modification, the interior of the absorbent article 6 was composed of the mat 61, but a SAP sheet 65 may be used in addition to the mat 61. The SAP sheet is a sheet made of a fibrous material and carrying a SAP layer formed by including particles of a superabsorbent polymer, hereinafter also referred to as "SAP particles". When sandwiching the SAP layer between two sheets, both sheets are formed of a fibrous material. And, for the sheet disposed at least on the skin side, a hydrophilic sheet is adopted. As such a sheet, as an example, a nonwoven fabric made of synthetic fibers such as polypropylene (PP) fibers and polyethylene terephthalate (PET) fibers can be mentioned. The "nonwoven fabric" can be, for example, a sheet or web formed by adhering or entangling short fibers or filaments made of non-cellulose synthetic fibers. In order to make the sheet hydrophilic, a hydrophilization treatment such as applying, spraying, or impregnating a surfactant to the raw cotton of the nonwoven fabric may be performed.

[0034] The SAP particles used in the SAP sheet 65 are granular SAP, and for example, those capable of absorbing and retaining water more than five times their own weight can be adopted. Also, as the SAP, SAPs such as starch-based, cellulose-based, and synthetic resin-based can be used. For example, it may be composed of a starch-acrylic acid (salt) graft copolymer, a saponified product of a starch-acrylonitrile copolymer, a crosslinked product of sodium carboxymethyl cellulose, or an acrylic acid (salt) polymer. Also, regarding the particle shape of the SAP, for example, crushed type and pearl type are known.

[0035] This second modification example is the same as the first modification example, except that the peripheral absorption portion 61A of the first modification example is replaced with the SAP sheet 65. Therefore, in this second modification example, the portion of the peripheral region 6S is further lower by the amount that the thickness of the SAP sheet 65 is thinner than that of the peripheral absorption portion 61A, compared to the first modification example. However, also in this second modification example, the portion of the peripheral region 6S is higher by the thickness of the SAP sheet 65, compared to the portion of the central region 6C. Therefore, also in this second modification example, similar to the above-described embodiment and the first modification example, even when a load is applied to the outer surface located on the non-skin surface side of the absorbent article 6 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. For this reason, even when the wearer wearing the absorbent article 6 sits on a chair, in the portion of the central region 6C, the space between the mat 61 and the skin surface H of the wearer is maintained. For this reason, 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 a flow path is almost lost, the space of the portion of the central region 6C maintained between the mat 61 and the wearer by the SAP sheet 65 maintains the function as a flow path.

[0036] Further, the absorbent article 6 bends the skin surface side sheet 62 and the non-skin surface side sheet 63 with the SAP sheet 65 and the mat 61 sandwiched therebetween along the longitudinal direction of the absorbent article 6 on both the left and right sides of the virtual center line, so that a part of the bent non-skin surface side sheet 63 is sandwiched between the SAP sheet 65 and the mat 61. This non-skin surface side sheet 63 is liquid-impermeable as described above. For this reason, between the SAP sheet 65 and the mat 61, the liquid absorbed by the mat 61 does not easily flow. For this reason, the non-skin surface side sheet 63 sandwiched between the mat 61 and the SAP sheet 65 suppresses as much as possible the possibility that the liquid absorbed by the mat 61 comes into contact with the portion of the skin surface H facing the peripheral region 6S, similar to the above-described embodiment. Also, in the portion of the skin surface H facing the central region 6C, since the mat 61 is supported from the skin surface H side by the SAP sheet 65 and the central region 6C is less likely to come into contact with the skin surface H, the possibility that the liquid absorbed by the mat 61 of the absorbent article 6 comes into contact is suppressed as much as possible.

[0037] <Third Modified Example> FIG. 8 is a view showing a third modified example of the internal structure of the absorbent article 6. In this third modified example, the skin-side sheet 62 and the non-skin-side sheet 63 are not folded along the folded portion of the mat 61, but the mat 61 is folded to form a peripheral absorption portion 61A, a peripheral absorption portion 61B, and a central absorption portion 61C, and is sandwiched between the skin-side sheet 62 and the non-skin-side sheet 63.

[0038] Also in this third modified example, similar to the above-described embodiment, even when a load is applied to the outer surface located on the non-skin side of the absorbent article 6 and the central absorption portion 61C is pressed toward the skin side, the central absorption portion 61C is supported from the skin 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 wearer's skin surface H is maintained. For this reason, 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 a flow path is almost lost, the space in the portion of the central region 6C maintained between the central absorption portion 61C and the wearer by the peripheral absorption portions 61A and 61B maintains the function as a flow path. For this reason, 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.

[0039] <Fourth Modified Example> FIG. 9 is a view showing a fourth modified example of the internal structure of the absorbent article 6. This fourth modified example is basically the same as the third modified example, but the form of the skin-side sheet 62 is slightly different. That is, in the third modified example, the space in the portion 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 formed on the non-skin side of the skin-side sheet 62, in other words, inside the absorbent article 6. On the other hand, in this fourth modified example, since the skin-side sheet 62 is in a form that closely adheres to the shape of the mat 61, the space in the portion 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 formed on the skin side of the skin-side sheet 62.

[0040] Therefore, in this fourth modification example, when a load is applied to the outer surface located on the non-skin side of the absorbent article 6 and the central absorption portion 61C is pressed toward the skin side, the space between the central absorption portion 61C and the wearer's skin surface H is maintained. In addition to the space functioning as a flow path, the space can also function as a space for accommodating solid matter such as feces.

[0041] <Fifth Modification Example> FIG. 10 is a diagram showing a fifth modification example of the internal structure of the absorbent article 6. In this fifth modification example, the peripheral absorption portion 61A and the central absorption portion 61C are not connected and are separate. Further, in this fifth modification example, the skin-side sheet 62 and the non-skin-side sheet 63 are not sandwiched between the folded-back portions of the mat 61 or the like, and the state in which the peripheral absorption portion 61A and the central absorption portion 61C are overlapped is sandwiched between the skin-side sheet 62 and the non-skin-side sheet 63.

[0042] Also in this fifth modification example, similar to the above-described embodiments and modification examples, even when a load is applied to the outer surface located on the non-skin side of the absorbent article 6 and the central absorption portion 61C is pressed toward the skin side, the central absorption portion 61C is supported from the skin side by the peripheral absorption portion 61A. For this reason, in the portion of the central region 6C, the space between the central absorption portion 61C and the wearer's skin surface H 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 a flow path is almost lost, the space in the portion of the central region 6C maintained between the central absorption portion 61C and the wearer by the peripheral absorption portion 61A maintains the function as a flow path. For this reason, 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.

[0043] <Sixth Modification Example> FIG. 11 is a diagram showing a sixth modification of the internal structure of the absorbent article 6. This sixth modification is basically the same as the fifth modification, but the form of the skin-side sheet 62 is slightly different. That is, in the fifth modification, the space in the central region 6C formed between the central absorbent portion 61C and the skin surface H by the peripheral absorbent portion 61A is formed on the non-skin side of the skin-side sheet 62, in other words, inside the absorbent article 6. On the other hand, in this sixth modification, since the skin-side sheet 62 is in a form that adheres along the shape of the mat 61, the space in the portion of the central region 6C formed between the central absorbent portion 61C and the skin surface H by the peripheral absorbent portion 61A is formed on the skin side of the skin-side sheet 62.

[0044] Therefore, in this sixth modification, when a load is applied to the outer surface located on the non-skin side of the absorbent article 6 and the central absorbent portion 61C is pressed toward the skin side, the space between the central absorbent portion 61C and the wearer's skin surface H is maintained. In addition to the space functioning as a flow path, the space can also function as a space for accommodating solids such as feces.

[0045] <Seventh Modification> FIG. 12 is a diagram showing a seventh modification of the internal structure of the absorbent article 6. This seventh modification has basically the same structure as the fifth modification, but is provided with a SAP sheet 65 instead of the peripheral absorbent portion 61A.

[0046] Also in this seventh modification, similar to the above-described embodiments and each modification, when a load is applied to the outer surface located on the non-skin side of the absorbent article 6 and the mat 61 is pressed toward the skin side, the mat 61 is supported from the skin side by the SAP sheet 65. For this reason, 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 a flow path is almost lost, the space in the portion of the central region 6C maintained between the mat 61 and the wearer by the SAP sheet 65 retains the function as a flow path. For this reason, the liquid discharged from the wearer can be diffused in the longitudinal direction of the absorbent article 6, and the liquid can be absorbed throughout the absorbent article 6.

[0047] <Eighth Modification Example> FIG. 13 is a diagram showing an eighth modification example of the internal structure of the absorbent article 6. This eighth modification example is the same as the above-described embodiment except that an SAP sheet 65 is added to the skin surface side of the peripheral absorbent portion 61A in the above-described embodiment. Therefore, in this eighth modification example, compared with the above-described embodiment, the peripheral region 6S is further increased by the thickness of the SAP sheet 65. Therefore, when the central absorbent portion 61C is pressed toward the skin surface side in this eighth modification example, the central absorbent portion 61C is supported from the skin surface side by the peripheral absorbent portion 61A, the peripheral absorbent portion 61B, and the SAP sheet 65. For this reason, in the portion of the central region 6C, the space between the central absorbent portion 61C and the wearer's skin surface H is more surely maintained than in the above-described embodiment. Therefore, even when the central absorbent 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 a flow path is almost lost, the central region 6C maintained between the central absorbent portion 61C and the wearer by the peripheral absorbent portion 61A, the peripheral absorbent portion 61B, and the SAP sheet 65 The space of the portion functions as a flow path. For this reason, 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.

[0048] Also, in this eighth modification example as well, the absorbent article 6 has, on both the left and right sides of the virtual center line, the skin-side sheet 62 and the non-skin-side sheet 63 with the peripheral absorption part 61A and the central absorption part 61C sandwiched therebetween, and is folded along the longitudinal direction of the absorbent article 6, so that a part of the folded non-skin-side sheet 63 is sandwiched between the peripheral absorption part 61A and the central absorption part 61C. Therefore, the non-skin-side sheet 63 sandwiched between the peripheral absorption part 61A and the central absorption part 61C, similar to the above-described embodiment, suppresses as much as possible the possibility that the liquid absorbed by the central absorption part 61C contacts the part of the skin surface H facing the peripheral region 6S. Also, in the part of the skin surface H facing the central region 6C, since the central absorption part 61C is supported from the skin surface H side by the peripheral absorption part 61A, the peripheral absorption part 61B, and the SAP sheet 65, and the central region 6C is less likely to contact the skin surface H, the possibility that the liquid absorbed by the central absorption part 61C of the absorbent article 6 contacts is suppressed as much as possible.

[0049] Note that this eighth modification example is also effective when it is desired to make the mat 61 thinner. When the peripheral absorption part 61A and the peripheral absorption part 61B are provided by folding back the mat 61, it is necessary to make the mat 61 itself thinner to some extent so that the mat 61 can be folded. When the mat 61 is made thinner, the absorption capacity of the mat 61 itself decreases. In this regard, in the case of this eighth modification example in which the SAP sheet 65 is overlapped with the peripheral absorption part 61A, it is possible to compensate for the absorption capacity of the peripheral absorption part 61A composed of the thin mat 61 with the SAP sheet 65.

[0050] <Other Modification Examples> Also, the internal structure of the absorbent article 6 can be made into an appropriate structure by further combining the above-described embodiment and each modification example. Also, it is possible to replace all of the mats 61 with SAP sheets.

[0051] <First Application Example> Hereinafter, the case where the absorbent article 6 of the above-described embodiment and each modification example is applied to a diaper will be exemplified. In this first application example, the case of a so-called tape-type diaper will be exemplified, but it can be similarly applied to pants-type diapers and pads.

[0052] Figure 14 is a perspective view of the diaper. The diaper 1 has a crotch region 1B which is a part corresponding to the crotch region covering the wearer's crotch in the worn state, a front body region 1F which is located on the front side of the crotch region 1B and corresponds to the front body of the wearer, and a back body region 1R which is located on the rear side of the crotch region 1B and corresponds to the back body of the wearer. Tapes 2L and 2R that can be attached to a front patch 2F provided on the non-skin side surface of the front body region 1F are provided at the left and right edges of the back body region 1R. Therefore, when the tapes 2L and 2R are attached to the front patch 2F with the front body region 1F arranged on the ventral side of the wearer and the back body region 1R arranged on the dorsal side of the wearer, the diaper 1 is fixed to the wearer's body in a state of surrounding the wearer's abdominal circumference and thighs. Since the diaper 1 is fixed to the wearer's body in such a form, the wearer can walk around while wearing the diaper 1.

[0053] An absorber that can absorb and hold liquid is mainly arranged around the crotch region 1B in the diaper 1. The absorber that absorbs and holds liquid is provided in the diaper 1 in a form sandwiched between a back sheet 5 forming the outer surface of the diaper 1 and a top sheet 7 forming a skin contact surface inside the diaper 1. Further, in the diaper 1, three-dimensional gathers 3BL and 3BR are provided at the part surrounding the wearer's thighs, and a waist gather 3R is provided at the part surrounding the wearer's abdominal circumference in order to suppress the formation of a gap serving as a liquid outflow path between the diaper 1 and the wearer's skin. The three-dimensional gathers 3BL, 3BR and the waist gather 3R adhere to the wearer's skin by the elastic force of the thread rubber. Therefore, the liquid excreted from the wearer's crotch is absorbed by the absorber of the diaper 1 with almost no leakage from the diaper 1.

[0054] When applying the absorbent article 6 of the above-described embodiment and each modification example to the diaper 1 in such a form, the skin-side sheet 62 corresponds to the top sheet 7, the non-skin-side sheet 63 corresponds to the back sheet 5, and the mat 61 corresponds to the absorbent body provided between the top sheet 7 and the back sheet 5. When the absorbent article 6 is applied to such a diaper 1, in the front crotch region 1F and the back crotch region 1R, a folded-back portion provided in the absorbent article 6 can be formed. However, when worn, by attaching the tapes 2L and 2R to the front patch 2F, the folded-back portion is pulled and spreads as shown in FIG. 14. However, if the folded-back state of the folded-back portion is maintained in the crotch region 1B and its vicinity, the support function by the peripheral absorbent portion 61A and the like when the wearer sits on a chair or the like is exhibited as described in the above embodiment.

[0055] <Second Application Example> Hereinafter, the case where the absorbent article 6 of the above-described embodiment and each modification example is applied to a pad will be exemplified. FIG. 15 is a perspective view of the pad. The pad 11 is used to absorb and hold liquids such as urine and can be used alone or stacked inside a disposable diaper such as the diaper 1. The pad 11 is divided, when viewed in the longitudinal direction, into a crotch region 15 that covers the wearer's genitals, a front crotch region 14 located on the abdominal side of the wearer, and a back crotch region 16 located on the back side of the wearer. In FIG. 15, the pad 11 has the narrowest width in the crotch region 15, and the crotch region 15 has an hourglass shape with a constriction. However, the pad 11 is not limited to such a form and may be, for example, a non-hourglass shape without constriction, such as a substantially rectangular shape.

[0056] As shown in FIG. 15, the pad 11 includes a topsheet 12 disposed on the skin-facing surface side in the worn state. The topsheet 12 is the portion (skin-facing surface) that contacts the wearer's skin in the worn state of the pad 11 and is formed of a liquid-permeable material that allows liquids such as urine to pass through. Further, the pad 11 includes a backsheet 13 disposed on the opposite side of the skin-facing surface in the worn state. The backsheet 13 is the portion that becomes the non-skin-facing surface (outer surface) opposite to the skin-facing surface throughout the pad 11 and is formed of a liquid-impermeable material that does not allow liquids such as urine to pass through. The peripheral edges of the topsheet 12 and the backsheet 13 are joined to each other. Also, an absorber for absorbing liquids such as urine is disposed between the topsheet 12 and the backsheet 13.

[0057] The pad 11 is provided with an absorber that can absorb and hold liquids. The absorber that absorbs and holds liquids is provided in the pad 11 in a form sandwiched between the backsheet 13 that forms the exterior surface of the pad 11 and the topsheet 12 that forms the skin-contact surface inside the pad 11. Therefore, the liquid excreted from the wearer's genital area is absorbed by the absorber in the pad 11 through the topsheet 12.

[0058] When applying the absorbent article 6 of the above-described embodiment and each modification to the pad 11 of such a form, the skin-side sheet 62 corresponds to the topsheet 12, the non-skin-side sheet 63 corresponds to the backsheet 13, and the mat 61 corresponds to the absorber provided between the topsheet 12 and the backsheet 13. Even when the absorbent article 6 is applied to the pad 11 of such a form, when the wearer sits on a chair or the like, the support function by the peripheral absorption portion 61A and the like is exhibited as described in the above embodiment.

[0059] The functions exhibited when applying the absorbent article 6 of the above-described embodiment and modification to the diaper 1, the pad 11, etc. will be described below.

[0060] <Slit alternative function> FIG. 16 is a view showing a state in which the crotch region 1B of the diaper 1 is pressed by the lower limbs of the wearer from both left and right sides when the diaper 1 is worn. When the diaper 1 is worn by the wearer, the crotch region 1B of the diaper 1 is sandwiched by the lower limbs of the wearer from both left and right sides. For this reason, the crotch region 1B of the diaper 1 has a form as if it is sandwiched and crushed from both left and right sides as shown in FIG. 16. The same applies to the pad 11 and the pant-type diaper. Therefore, when the absorbent article 6 is applied to the diaper 1, the absorbent article 6 is as follows.

[0061] FIG. 17 is a first view exemplifying a state in which the slit 61S is closed. When the diaper 1 or the pad 11 to which the absorbent article 6 is applied is worn by the wearer, the absorbent article 6 is sandwiched by the lower limbs of the wearer from both left and right sides. For this reason, the absorbent article 6 is in a state of narrowing from both left and right sides toward the virtual center line in the longitudinal direction as shown in FIG. 17. For this reason, the effective area as a flow path of the slit 61S provided in the central absorption portion 61C becomes smaller than before wearing. However, a predetermined distance L2 is secured between the end portion on the central region 6C side of the peripheral region 6S in the width direction and the end portion on the peripheral region 6S side of the slit 61S in the width direction, and the end portion on the peripheral region 6S side of the slit 61S in the width direction is arranged more inward in the width direction than the end portion on the central region 6C side of the peripheral region 6S in the width direction. Even if the slit 61S is closed, a space having a width of at least (L2×2), indicated by a broken line in FIG. 17, is secured in the portion of the central region 6C. For this reason, the absorbent article 6 is in a state of narrowing from both 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 portion of the central region 6C serves as a flow path for flowing the liquid instead of the slit 61S. For this reason, the liquid such as urine discharged from the wearer diffuses in the longitudinal direction of the absorbent article 6 through the space in the central region 6C, and the absorbent article 6 can absorb the liquid throughout. Such an effect is similarly exhibited even when the SAP contained in the vicinity of the slit 61S of the central absorption portion 61C swells due to water absorption and the swollen SAP closes the slit 61S.

[0062] In addition, since the slit 61S is configured to penetrate the central absorption portion 61C, the actual dimensions of the slit 61S may be narrower than the design due to the deformation of the material forming the central absorption portion 61C at the edge of the slit 61S. In this regard, the peripheral absorption portions 61A and 61B that form a space in the central region 6C are configured such that the portion facing the space is covered by the skin-side sheet 62. Therefore, even if the material forming the peripheral absorption portions 61A and 61B is deformed, the portion of the central region 6C is less likely to be narrowed due to such deformation. Thus, the shape of the space formed in the central region 6C is more reliably maintained than the slit 61S.

[0063] <Slit holding function>

[0064] FIG. 18 is a second diagram illustrating the state in which the slit 61S is closed. In FIG. 18, the slit 61S is wider than in FIG. 17. For example, as shown in FIG. 18, a predetermined distance L3 is secured between the end on the central region 6C side of the peripheral region 6S in the width direction and the end on the peripheral region 6S side of the slit 61S in the width direction, and the end on the peripheral region 6S side of the slit 61S in the width direction is arranged outside the width direction of the end on the central region 6C side of the peripheral region 6S in the width direction. Even if the space in the portion of the central region 6C is closed, at least a lateral width of (L3×2) is secured in the portion of the slit 61S. For this reason, the absorbent article 6 becomes narrower from both the left and right sides toward the virtual center line in the longitudinal direction. Even when the space in the portion of the central region 6C is closed, the slit 61S does not lose its function as a flow path for flowing the liquid. 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 absorbent article 6 can absorb the liquid throughout. Note that when the space in the portion of the central region 6C is closed The liquid flowing through the slit 61S will flow through the slit 61S in a state of being hidden from the skin side of the absorbent article 6, and thus can be regarded as seepage water. The liquid flowing through the slit 61S in a state like seepage water is less likely to adhere to the wearer's skin. Therefore, in such a form, it is possible to suppress as much as possible the possibility of liquid such as urine adhering to the wearer's skin.

[0065] <Male organ support function> FIG. 19 is a view showing the parts corresponding to the urethral orifice and the anus. For example, when the absorbent article 6 has a length (for example, about 56 cm) reaching from the front body of the wearer through the crotch region to the back body, as shown in FIG. 19, in the central region 6C of the absorbent article 6, the urethral orifice facing region R1 and the anus facing region R2 are arranged along the longitudinal direction of the absorbent article 6. The urethral orifice of the wearer is located slightly in front of the wearer's crotch. Therefore, the urethral orifice facing region R1 is located slightly on the front body side rather than at the center in the longitudinal direction of the absorbent article 6. Also, the anus of the wearer is located slightly behind the wearer's crotch. Therefore, the anus facing region R2 is located slightly on the back body side rather than at the center in the longitudinal direction of the absorbent article 6.

[0066] When urine is discharged from the urethral orifice of the wearer, the urine flows through the slit 61S and the like from the urethral orifice facing region R1 and diffuses to each part of the absorbent article 6, and is absorbed by the mat 61 and the SAP sheet 65. When feces are discharged from the anus of the wearer, the feces adhere to the vicinity of the anus facing region R2 in the central region 6C.

[0067] When the absorbent article 6 is worn by a male, the male organ is held in the space of the central region 6C. FIG. 20 is a view showing how the male organ is supported. In FIG. 20, in the absorbent article 6 of the above-described embodiment, a cross-section when the absorbent article 6 is cut along the symbol C-C shown in FIG. 19 is illustrated. However, it is not limited to the absorbent article 6 of the embodiment, and the same applies to any of the above-described modified examples.

[0068] When the central absorption part 61C is worn at a position covering the male genital organ D of a male wearer, the peripheral absorption parts 61A and 61B that overlap the central absorption part 61C from the skin 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 can support the male genital organ D covered by the central absorption part 61C from both sides in the width direction of the absorbent article 6. Therefore, the male genital organ D is held along the virtual center line of the absorbent article 6. For this reason, the possibility that the tip of the male genital organ D with the urethral orifice deviates to the left and right from the virtual center line of the absorbent article 6 is suppressed. If the tip of the male genital organ D is held along the virtual center line of the absorbent article 6, when urine is discharged from the urethral orifice at the tip of the male genital organ D, the urine diffuses substantially evenly to both the left and right sides of the virtual center line in the absorbent article 6. Therefore, compared with an absorbent article in which the male genital organ D is not supported from both sides in the width direction, the possibility of urine leaking from the absorbent article 6 can be suppressed as much as possible.

[0069] In addition, in order to effectively exert the supporting function of the male genital organ D, the width of the central region 6C, in other words, the length of (L1×2) is preferably set in consideration of the standard thickness of the male genital organ of a male assumed to be worn, at least in the vicinity of the urethral orifice facing region R1. If the width of the central region 6C is too large, the male genital organ D will not be supported by the peripheral absorption parts 61A and 61B. Also, if the width of the central region 6C is too small, the male genital organ D will not fit in the part of the central region 6C, and the male genital organ D will not be supported by the peripheral absorption parts 61A and 61B. Therefore, the width of the central region 6C at least in the vicinity of the urethral orifice facing region R1 is, for example, within the range of 10 to 80 mm, more preferably within the range of 20 to 70 mm, and even more preferably within the range of 30 to 60 mm.

[0070] In addition, in order to effectively exert the supporting function of the male genital organ D, the height difference between the central region 6C and the peripheral region 6S is preferably set in consideration of the standard thickness of the male genital organ of a male assumed to be worn, at least in the vicinity of the urethral orifice facing region R1. The width of the central region 6C If it is too small, it is because the supporting force from the left and right sides of the peripheral absorption parts 61A and 61B for the male genital organ D is significantly lost. Therefore, the height difference in the vicinity of at least the urethral orifice facing area R1 is, for example, within a range of 2 to 30 mm, more preferably within a range of 5 to 25 mm, and even more preferably within a range of 10 to 20 mm.

[0071] In addition, the absorbent article 6 may be worn in a state where the tip of the male genital organ D faces downward toward the wearer's crotch, or may be worn in a state where the tip of the male genital organ D faces forward toward the wearer's front body. However, from the viewpoint of absorbing urine throughout the absorbent article 6, the former wearing state is preferable.

[0072] <Feces storage function> FIG. 21 is a view showing a state in which feces are stored. In FIG. 21, in the absorbent article 6 of the above-described embodiment, a cross-section when the absorbent article 6 is cut along the line D-D shown in FIG. 19 is illustrated. 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 modified examples.

[0073] When the central absorption part 61C is mounted at a position covering the wearer's anus, the peripheral absorption parts 61A and 61B that overlap the central absorption part 61C from the skin side at positions on the left and right sides with a predetermined distance L1 from the virtual center line of the absorbent article 6 form a wall part of a storage part capable of storing feces B between the central absorption part 61C and the wearer's anus. Therefore, the feces discharged from the wearer's anus are discharged into a storage part (the space of the central region 6C) where the wall part is formed by the peripheral absorption parts 61A and 61B and the bottom surface is formed by the central absorption part 61C. Therefore, compared with an absorbent article in which such a storage part is not formed, the possibility of feces leaking out from the absorbent article 6 can be suppressed as much as possible.

[0074] In order to effectively utilize the storage function of feces B, the width of the central region 6C, that is, the length of (L1×2), is preferably set in consideration of the standard defecation volume of the assumed wearer, at least in the vicinity of the anus-facing region R2. This is because if the width of the central region 6C is too small, feces B will not fit in the central region 6C. Therefore, the width of the central region 6C in the vicinity of at least the anus-facing region R2 is, for example, 10 mm or more, more preferably 20 mm or more, and even more preferably 30 mm or more.

[0075] Also, in order to effectively utilize the storage function of feces B, the height difference between the central region 6C and the peripheral region 6S is preferably set in consideration of the standard defecation volume of the assumed wearer, at least in the vicinity of the anus-facing region R2. This is because if the width of the central region 6C is too small, feces B will not fit in the central region 6C. Therefore, the height difference in the vicinity of at least the anus-facing region R2 is, for example, 2 mm or more, more preferably 5 mm or more, and even more preferably 10 mm or more. However, even if the feces do not completely fit in the storage portion, the storage portion can still function to hold the feces. Therefore, it is not always necessary to design the absorbent article 6 such that the storage portion has dimensions that can completely contain the feces.

[0076] As described above, the various functions of the above-described embodiments and each modification have been explained. However, the absorbent article 6 is not limited to those that exhibit only such functions. The absorbent article 6 can also exhibit functions such as, for example, cushioning an external impact transmitted to the wearer's buttocks, keeping the wearer's buttocks warm, and various other functions.

[0077] <Manufacturing apparatus> FIG. 22 is a diagram showing an example of an apparatus for manufacturing the absorbent article 6. The absorbent article 6, for example, when a flat, long intermediate product C that has not been folded is continuously fed in, has a folding mechanism that folds both the left and right sides in the width direction of the intermediate product C into a Z-shaped cross-section and discharges them. It can be manufactured by the built-in manufacturing apparatus M. The folding mechanism in the manufacturing apparatus M includes, for example, a first roller that gradually raises both the left and right sides in the width direction of the intermediate product C, and a first sealer that folds the raised portion of the intermediate product C raised by the first roller so as to wrap it around the central portion side in the width direction at a portion that is a predetermined first distance from both the left and right end portions in the width direction of the intermediate product C, a second roller that gradually raises both the left and right sides in the width direction of the intermediate product C, and a second sealer that folds the raised portion of the intermediate product C raised by the second roller so as to fold it outward in the width direction at a portion that is a predetermined second distance shorter than the predetermined first distance from both the left and right end portions in the width direction of the intermediate product C, and the like.

[0078] For a manufacturing apparatus M incorporating such a folding mechanism, for example, an intermediate product C with only a mat 61 sandwiched between the skin-side sheet 62 and the non-skin-side sheet 63 is prepared, and by simply feeding the intermediate product C into the manufacturing apparatus M, it is possible to continuously manufacture the absorbent article 6.
