  FIG. 1 is a plan view showing a male light incontinence pad 1 according to an embodiment of the present invention in an unfolded state. The light incontinence pad 1 for men (hereinafter simply referred to as “light incontinence pad 1”) is attached to the inside of the underwear worn by the wearer (that is, the wearer's side) to remove excrement such as urine from the wearer. It is an absorbent article to receive. The male light incontinence pad 1 may be attached to the inside of a disposable diaper or the like worn by the wearer. In FIG. 1, the light incontinence pad 1 is drawn with the surface on the side in contact with the wearer when worn.

  2 to 4 respectively show the light incontinence pad 1 perpendicular to the longitudinal direction (ie, the vertical direction in FIG. 1) at the positions II-II, III-III and IV-IV shown in FIG. It is sectional drawing cut | disconnected by the plane. 2 to 4, the components of the light incontinence pad 1 are illustrated separately in the thickness direction for convenience of illustration.

  As shown in FIGS. 1 to 4, the light incontinence pad 1 includes a sheet-like main body 2 that extends in the longitudinal direction and a cover 3 that covers one surface (main surface) of the main body 2. The main body 2 includes a liquid-permeable top sheet 21, a water-repellent or liquid-impervious back sheet 23, a sheet-like absorbent core 22, and water-absorbing paper 24. The absorbent core 22 is disposed between the top sheet 21 and the back sheet 23. The water absorbent paper 24 is disposed between the absorbent core 22 and the back sheet 23. In FIG. 1, the broken line indicating the outline of the absorbent core 22 is thicker than the broken line indicating the outline of the water absorbent paper 24 in order to facilitate understanding of the drawing. In the plan view of the light incontinence pad 1, the entire water absorbent paper 24 is located inside the outer peripheral edge of the main body 2, and the entire absorbent core 22 is located inside the outer peripheral edge of the water absorbent paper 24.

  As shown in FIGS. 2 to 4, the top sheet 21 covers the main surface of the absorbent core 22 on the wearer side. The water absorbent paper 24 covers the other main surface of the absorbent core 22, that is, the main surface opposite to the wearer. The back sheet 23 covers the surface of the water absorbent paper 24 opposite to the absorbent core 22, that is, the surface opposite to the wearer. The top sheet 21 is joined to the water absorbent paper 24 by a hot melt adhesive or the like around the absorbent core 22. In the light incontinence pad 1, the sheet laminate 20 that defines the outer shape of the main body 2 is formed by the top sheet 21, the cover 3, and the backsheet 23. The sheet laminated body 20 has a shape extending in the longitudinal direction in the same manner as the main body 2.

  The top sheet 21 is a liquid-permeable sheet member that quickly captures moisture of excrement from the wearer and moves it to the absorbent core 22. The absorbent core 22 absorbs moisture that has passed through the top sheet 21 and quickly fixes it. The water absorbent paper 24 absorbs moisture that has passed through the absorbent core 22. The back sheet 23 prevents moisture that has reached the back sheet 23 from oozing out of the main body 2.

  As will be described later, in a state where the wearer wears the light incontinence pad 1, one end portion of the light incontinence pad 1 in the longitudinal direction (the upper end portion in FIG. 1) is the front end portion 11 below the wearer. Contact the abdomen. Further, the other end portion (the lower end portion in FIG. 1) of the light incontinence pad 1 faces the wearer's crotch portion as a crotch lower end portion 12. Actually, the portion of the light incontinence pad 1 on the front end 11 side in the longitudinal direction, that is, the portion including the front end 11 when the light incontinence pad 1 is roughly divided into two in the longitudinal direction is the wearer's male. Touch the vessel. In the following description, the portion of the light incontinence pad 1 is referred to as the “front portion 110”, and the remaining portion of the light incontinence pad 1, that is, the portion on the crotch lower end 12 side of the light incontinence pad 1 in the longitudinal direction is referred to as “inseam”. Part 120 ".

  The width of the light incontinence pad 1 in the width direction perpendicular to the longitudinal direction, that is, the width of the sheet laminate 20 changes along the longitudinal direction, and the front end portion 11 is a portion where the width of the sheet laminate 20 is maximum. including. The width of the sheet laminate 20 gradually decreases from the front end portion 11 toward the crotch lower end portion 12. For example, each side edge of the sheet laminate 20 between the front end 11 and the crotch lower end 12 is linear, and the width of the sheet laminate 20 is linear from the front end 11 toward the crotch lower end 12. To decrease. Thus, in the sheet laminated body 20, the width of the crotch lower end portion 12 in the width direction is smaller than the width (maximum width) of the front end portion 11. The shape of the sheet laminate 20 can also be regarded as a substantially triangular shape.

  As the above-mentioned hot melt adhesive, those of polyolefin type, rubber type, vinyl acetate type and the like are used. The top sheet 21, the water absorbent paper 24, and the back sheet 23 may be joined by other joining methods (for example, heat fusion joining, ultrasonic joining, or the like). The same applies to other parts where the hot melt adhesive is used for bonding.

  As the top sheet 21, for example, a liquid-permeable non-woven fabric formed of hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.) whose surface is hydrophilically treated with a surfactant is used. The said nonwoven fabric is a point bond nonwoven fabric, an air through nonwoven fabric, and a spun bond nonwoven fabric, for example. In addition, as the top sheet 21, a nonwoven fabric (for example, a spunlace nonwoven fabric) formed of hydrophilic fibers such as cellulose, rayon, or cotton may be used.

  As the back sheet 23, a water-repellent or liquid-impervious nonwoven fabric (for example, a spunbond nonwoven fabric, a meltblown nonwoven fabric, an SMS (spunbond / meltblown / spunbond) nonwoven fabric) formed of hydrophobic fibers, A liquid-impervious plastic film or a laminated sheet in which any nonwoven fabric and a plastic film are laminated is used. From the viewpoint of preventing wear of the light incontinence pad 1 and improving the comfort of the wearer, the plastic film used in the back sheet 23 preferably has moisture permeability (breathability).

  As shown in FIGS. 2 to 4, the absorbent core 22 includes a plurality of absorbent sheets 220. In an example of the light incontinence pad 1, two absorbent sheets 220 having the same structure are provided and are accurately stacked in the thickness direction (vertical direction in FIGS. 2 to 4). As will be described later, the outer shape of each absorbent sheet 220 is rectangular. When the light incontinence pad 1 is viewed in plan as shown in FIG. 1, the outer shape of the absorbent core 22 matches the outer shape of the absorbent sheet 220 and is rectangular. In the following description, when the two absorbent sheets 220 shown in FIGS. 2 to 4 are distinguished, the absorbent sheet 220 that contacts the top sheet 21 is referred to as an “upper absorbent sheet 220”, and the absorbent sheet that contacts the water absorbent paper 24. 220 is referred to as a “lower absorbent sheet 220”. In the absorbent core 22, only one absorbent sheet 220 may be provided.

  Each absorbent sheet 220 includes a liquid-permeable upper layer sheet 221, a liquid-permeable lower layer sheet 222, and a superabsorbent material layer 223. The upper layer sheet 221 is disposed between the top sheet 21 and the lower layer sheet 222. The lower layer sheet 222 is disposed between the upper layer sheet 221 and the back sheet 23. The superabsorbent material layer 223 is a layer composed of the superabsorbent material 224. In FIGS. 2-4, the superabsorbent material 224 is shown abstractly with white circles. The superabsorbent material layer 223 is disposed between the upper layer sheet 221 and the lower layer sheet 222 and is fixed to one or both by a hot melt adhesive or the like. The superabsorbent material layer 223 is in contact with both the upper layer sheet 221 and the lower layer sheet 222 (including the case of contacting via an adhesive). The upper layer sheet 221 and the lower layer sheet 222 are overlapped and joined to each other in a region where the superabsorbent material 224 is not present. In the preferred absorbent sheet 220, only the superabsorbent material 224 is present between the upper layer sheet 221 and the lower layer sheet 222 except for the adhesive in principle.

  FIG. 5 is a plan view showing the absorbent sheet 220. The outer shape of each absorbent sheet 220 is a rectangle (rectangle) that is long in the longitudinal direction. Similarly, the upper layer sheet 221 and the lower layer sheet 222 have shapes extending in the longitudinal direction. In the absorbent sheet 220, a plurality of material presence regions 225 and a plurality of material absence regions 226 are provided. In each material existence region 225, the superabsorbent material 224 is disposed between the upper layer sheet 221 and the lower layer sheet 222. That is, the superabsorbent material 224 is fixed to the plurality of material existence regions 225. In FIG. 5, a parallel oblique line is given to the material existence region 225.

  Each of the plurality of material existence regions 225 has a strip shape extending substantially parallel to the longitudinal direction, and is arranged while being separated from each other in the width direction. That is, the absorbent sheet 220 is provided with a plurality of material existence regions 225 arranged in a stripe shape extending in the longitudinal direction. In the example of FIG. 5, the plurality of material existence regions 225 have the same width (width in the width direction). For example, the basis weight (weight per unit area) of the superabsorbent material 224 in the plurality of material existence regions 225 is approximately equal.

  The plurality of material absence regions 226 are regions in the absorbent sheet 220 excluding the plurality of material presence regions 225. Each of the plurality of material absence regions 226 has a strip shape extending along the longitudinal direction. In the example of FIG. 5, the width of each material absence region 226 in the width direction is smaller than the width of the material presence region 225. The widths of the plurality of material absence regions 226 are equal to each other. The plurality of material absence regions 226 and the plurality of material presence regions 225 are alternately arranged in the width direction.

  In each material absence region 226, there is no superabsorbent material between the upper layer sheet 221 and the lower layer sheet 222. In the material absence region 226, the upper layer sheet 221 and the lower layer sheet 222 are preferably bonded to each other by a bonding method that does not use an adhesive, such as heat fusion bonding or bonding by embossing. In the material absence region 226, the upper layer sheet 221 and the lower layer sheet 222 may be partially unbonded. Even if the material absence region 226 is a region containing a little superabsorbent material, that is, a region where the density of the superabsorbent material 224 is lower than other regions (material present region 225) (material low density region). Good.

  As the upper layer sheet 221 and the lower layer sheet 222 of the absorbent sheet 220, for example, as with the top sheet 21, the surface is made of hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.) that are hydrophilically treated with a surfactant. A liquid permeable nonwoven fabric is used. The said nonwoven fabric is a point bond nonwoven fabric, an air through nonwoven fabric, and a spun bond nonwoven fabric, for example. Moreover, as the upper layer sheet 221 and the lower layer sheet 222, a nonwoven fabric (for example, spunlace nonwoven fabric) formed of hydrophilic fibers such as cellulose, rayon, or cotton may be used. As the upper layer sheet 221 and the lower layer sheet 222, a tissue, a plastic film having a plurality of openings, or the like may be used.

  As the superabsorbent material 224, for example, a granular superabsorbent polymer (SAP (Super Absorbent Polymer)) or a fibrous superabsorbent fiber (SAF (Super Absorbent Fiber)) is used. The superabsorbent material 224 is in principle formed of a polymer and does not contain pulp.

  A preferable absorbent core 22 includes only one or a plurality of absorbent sheets 220 and does not include a fiber aggregate layer for water absorption in which pulp fibers and the like are aggregated. That is, in the preferred light incontinence pad 1, a Palpress absorbent core 22 (so-called polymer sheet) is used. The thickness of such an absorption core 22 is, for example, 5 millimeters (mm) or less, and 1 mm or more. The upper absorbent sheet 220 and the lower absorbent sheet 220 may have different structures. For example, the positions of the plurality of material existence regions 225 in the width direction may be different between the upper absorbent sheet 220 and the lower absorbent sheet 220.

  Here, when the light incontinence pad 1 is viewed in plan as shown in FIG. 1, the area around the absorbent core 22 in the sheet laminate 20 is referred to as “absence area of the absorbent core 22” or “core absence area”. Call. As described above, the absorbent core 22 is rectangular, and the front end portion 11 includes a portion where the width of the sheet laminate 20 is maximum. Therefore, a relatively large core absence region exists on both sides of the front end portion 11.

  The water absorbent paper 24 is disposed between the lower layer sheet 222 and the back sheet 23 of the lower absorbent sheet 220 and covers the absorbent core 22 from the back sheet 23 side (see FIGS. 2 to 4). As shown in FIG. 1, the water absorbent paper 24 extends in the longitudinal direction from the front end portion 11 to the crotch lower end portion 12, and the length of the water absorbent paper 24 in the longitudinal direction is larger than the length of the absorbent core 22. The width of the water absorbent paper 24 in the width direction is larger than the width of the absorbent core 22 at any position in the longitudinal direction, and the entire absorbent core 22 is covered with the water absorbent paper 24 from the back sheet 23 side.

  The water absorbent paper 24 includes a part 241 having a constant width in the width direction and a part 242 having a width larger than that of the part 241. Hereinafter, these parts 241 and 242 are referred to as “narrow part 241” and “wide part 242”, respectively. The wide portion 242 is disposed at the front end portion 11, and a part of the narrow portion 241 is disposed at the crotch lower end portion 12. That is, the width of the water absorbent paper 24 at the crotch lower end 12 is smaller than the width of the water absorbent paper 24 at the front end 11. The width of the water absorbent paper 24 is maximum at the front end portion 11. As described above, a relatively large core absence region is located on both sides of the front end portion 11, and the wide portion 242 of the water absorbent paper 24 overlaps with the core absence region.

  The position in the longitudinal direction where the width of the water absorbent paper 24 is maximized is substantially the same as the position where the width of the sheet laminate 20 is maximized. As described above, the width of the sheet laminate 20 decreases linearly from the front end portion 11 toward the crotch lower end portion 12. In the water absorbent paper 24, the width of the wide portion 242 gradually decreases from the position in the longitudinal direction where the width is maximum toward the narrow portion 241, and the reduction amount is larger than the reduction amount of the width of the sheet laminate 20. . Therefore, in the portion on the narrow portion 241 side in the wide portion 242, the distance between the side edge and the side edge of the sheet laminate 20 gradually increases as the narrow portion 241 is approached in the longitudinal direction.

  Here, in each side part of the sheet laminated body 20, the region 201 between the side edge of the sheet laminated body 20 and the side edge of the water absorbent paper 24 is not arranged because both the absorbent core 22 and the water absorbent paper 24 are not arranged. It can be considered as an absorptive region. Further, the non-absorbable region 201 is preferably formed of a laminate of the cover portion 3 and the back sheet 23 without the top sheet 21 being disposed. The width of the non-absorbent region 201 in the width direction gradually increases from the longitudinal position where the widths of the sheet laminate 20 and the water absorbent paper 24 are maximized toward the boundary position between the wide portion 242 and the narrow portion 241. The maximum is obtained at the boundary position. The width of the non-absorbent region 201 at the position where the width is maximum is preferably 15 mm or more because it is easy to pick.

The water absorbent paper 24 is formed of, for example, pulp fibers. The basis weight of the water absorbent paper 24 is larger than the basis weight of the nonwoven fabric constituting the top sheet 21 and the back sheet 23. The basis weight of the water absorbent paper 24 is, for example, 20 g / m ² or more and 45 g / m ² or less, and preferably 30 g / m ² or more and 40 g / m ² or less. If it is 20 g / m ² or more, the water absorption amount and rigidity can be obtained. On the other hand, if it is 45 g / m ² or less, wet back of urine from the water absorbent paper 24 to the top sheet 21 can be suppressed. The thickness of the water absorbent paper 24 is smaller than the thickness of the absorbent core 22.

  The cover part 3 covers the surface of the main body part 2 on the top sheet 21 side. The cover part 3 includes a pair of water-repellent or liquid-impervious cover sheets 31 and a cover part elastic member 36. The pair of cover sheets 31 are respectively disposed on portions on both sides of the main body portion 2 in the width direction, that is, on two portions when the main body portion 2 is roughly divided into two in the width direction. Precisely, the two cover sheets 31 partially overlap each other in the center of the main body 2 in the width direction. Each cover sheet 31 extends over substantially the entire length of the main body 2 in the longitudinal direction.

  Each cover sheet 31 includes an outer edge 32 and an inner edge 33. When the light incontinence pad 1 is viewed in plan as shown in FIG. 6, the outer edge 32 is a portion that overlaps with the peripheral edge 29 (hereinafter referred to as “main body peripheral edge 29”) of the main body 2. The outer edge 32 is joined to the wearer-side surface (the top sheet 21, the water absorbent paper 24, the back sheet 23) of the main body 2 by a hot melt adhesive or the like. In FIG. 6, parallel oblique lines (parallel oblique lines having a wider interval than a joining portion 331 described later) are attached to the outer edge portion 32. Since each cover sheet 31 is disposed at one side of the main body 2 in the width direction, the outer edge 32 of the cover sheet 31 is joined to one side of the main body peripheral edge 29 in the width direction.

  In the example of FIG. 6, the main body peripheral edge portion 29 is a portion around the absorbent core 22 in the main body portion 2. The main body peripheral edge 29 may overlap the outer edge of the absorbent core 22. The outer edge 32 of the pair of cover sheets 31 overlaps with the peripheral edge of the main body 2 (the peripheral edge of the sheet laminate 20), and the surface on the wearer side of the light incontinence pad 1 in an expanded state. Is the surface of the cover sheet 31. In the center of the main body 2 in the width direction, at the portions of the outer edge portion 32 that overlap each other in the two cover sheets 31, these portions are also joined together by a hot melt adhesive or the like. In the cover part 3, the outer edge 32 of the pair of cover sheets 31 becomes the peripheral part of the cover part 3, and the peripheral part is joined to the main body peripheral part 29, so that the surface of the main body part 2 on the top sheet 21 side becomes. Covered by the cover 3.

  The inner edge 33 is a portion excluding the outer edge 32 in the peripheral edge of each cover sheet 31. The inner edge 33 extends in the longitudinal direction in the vicinity of the center of the main body 2 in the width direction. The edge of the inner edge 33 is preferably a straight line extending in the longitudinal direction. In a state where the main body 2 is extended in the longitudinal direction, the inner edge portions 33 of the pair of cover sheets 31 overlap each other along the longitudinal direction. That is, the inner edge portion 33 of the other cover sheet 31 is disposed so as to cover the wearer side surface of the inner edge portion 33 of the one cover sheet 31. For example, these inner edge portions 33 overlap each other over the entire length of the main body portion 2.

  Each inner edge portion 33 includes a joint portion 331 and a non-joint portion 332. The joint portion 331 is a portion of the inner edge portion 33 in the crotch portion 120. The joining portions 331 of the inner edge portions 33 in the pair of cover sheets 31 are joined together by a hot melt adhesive or the like (see FIG. 4). In FIG. 6, parallel diagonal lines with a smaller interval than the outer edge portion 32 are given to the joint portion 331. As described above, the inner edge portion 33 of the pair of cover sheets 31 is joined to each other at the crotch 120 side portion of the cover portion 3, so that the portion of the cover portion 3 forms a bag shape with the main body portion 2. A portion 34 is formed. In the bag-shaped portion 34, an internal space is formed in which each direction except the front portion 110 side is closed. The bag-like portion 34 can also be regarded as a pocket.

  The non-joining part 332 is a part of the inner edge part 33 in the front part 110. The non-joining portions 332 of the inner edge portions 33 in the pair of cover sheets 31 are not joined to each other (see FIGS. 2 and 3). Thereby, in a state where the wearer wears the light incontinence pad 1 as described later, an opening 35 into which the penis of the wearer's male genital is inserted (insertable) is formed. The non-joining part 332 of a pair of cover sheet 31 is an edge part of the opening part 35, and the opening part 35 is long in a longitudinal direction. In FIG. 1 and FIG. 6 which show the state which extended the light incontinence pad 1 to the longitudinal direction, the non-joining part 332 in a pair of cover sheet 31 has mutually overlapped.

  As described above, in the light incontinence pad 1, the opening 35 is formed in one part (the part on the front part 110 side) of the cover part 3 in the longitudinal direction, and the other part (the crotch part 120) of the cover part 3. A bag-like portion 34 is formed on the side portion. In the light incontinence pad 1 in which the opening 35 is formed at a position shifted from the center in the longitudinal direction, a large internal space can be secured in the bag-like portion 34. The width in which the two inner edge portions 33 overlap in the width direction is, for example, 5 mm or more. Thereby, sufficient joint strength is ensured in the joint part 331 of the two inner edge parts 33. Moreover, when the width | variety with which the two inner edge parts 33 overlap is too large, when inserting a male genitalia into the opening part 35, the operation | work which expands the opening part 35 becomes complicated. From such a viewpoint, the width in which the two inner edge portions 33 overlap in the width direction is preferably 10 mm or less.

  As shown in FIGS. 1 to 3, a cover elastic member 36 extending in the longitudinal direction is joined to the inner edge 33 of each cover sheet 31 in a stretched state by a hot melt adhesive or the like. In the example of FIGS. 2 and 3, in the sheet constituting the cover sheet 31, the cover elastic member 36 is provided between a folded portion whose side edge is folded back to the top sheet 21 side and a facing portion facing the folded portion. The cover elastic member 36 is joined to one or both of them. The tip of the folded portion is joined to the surface of the sheet on the main body 2 side. Here, the inner edge portion 33 includes a folded portion and a facing portion.

  As shown in FIG. 1, the cover elastic member 36 is provided in the non-joining portion 332, that is, provided along the edge of the opening 35. When the cover part elastic member 36 contracts along the edge of the opening 35, the non-joining part 332 of the two cover sheets 31 is separated from the main body part 2 toward the wearer as shown in FIGS. To do. Further, a gap in the width direction is generated between the non-joining portions 332 of the two cover sheets 31. That is, the state in which the opening 35 is opened in advance is maintained. Thereby, as will be described later, when the wearer wears the light incontinence pad 1, the male genitalia can be easily inserted into the opening 35. The non-joining portion 332 of the inner edge portion 33 can also be regarded as a free end portion of the cover sheet 31. The cover elastic member 36 is preferably provided over the entire non-joining portion 332 in the longitudinal direction. In addition to the non-joining part 332, the cover part elastic member 36 may be provided on a part or the whole of the joining part 331.

  As the cover sheet 31, a water-repellent or liquid-impervious nonwoven fabric (for example, a spunbond nonwoven fabric, a melt blown nonwoven fabric, or an SMS nonwoven fabric) formed of hydrophobic fibers is used. As the cover part elastic member 36, for example, a polyurethane thread, a strip-shaped polyurethane film, a thread-shaped or strip-shaped natural rubber, or the like is used, and the light incontinence pad 1 shown in FIG. 1 uses a polyurethane thread.

  FIG. 7 is a view showing the light incontinence pad 1 in a folded state. The light incontinence pad 1 is accommodated in a predetermined packaging bag 91 (shown by a broken line in FIG. 7) in a folded state. When the light incontinence pad 1 is folded, the light incontinence pad 1 is located on the cover part 3 side, that is, the cover, by two folding lines F1 and F2 (indicated by a one-dot chain line in FIG. 1) perpendicular to the longitudinal direction. It is bent so that the portion 3 is inside. One folding line F1 overlaps the opening 35 in the front portion 110, and the other folding line F2 is provided at a position away from the folding line F1 toward the crotch lower end 12 side.

  In the preferred light incontinence pad 1, an adhesive is applied to the surface of the back sheet 23 opposite to the top sheet 21, and a belt-like film covering almost the entire back sheet 23 is applied to the surface of the back sheet 23. Is affixed. The light incontinence pad 1 is folded to the cover part 3 side by two folding lines F1, F2 in a state where the film is adhered. The light incontinence pad 1 is accommodated in the packaging bag 91 formed by the film by bonding each side portion of the film folded together with the light incontinence pad 1 by a predetermined bonding method. In addition, the light incontinence pad 1 folded together with the film may be accommodated in the packaging bag 91 formed in a bag shape in advance. The light incontinence pad 1 may be fastened to the underwear by a tape piece of an adhesive tape (double-sided adhesive tape) or the like.

  When the wearer wears the light incontinence pad 1, the light incontinence pad 1 is taken out from the packaging bag 91, and the film attached to the back sheet 23 is peeled off. Subsequently, the light incontinence pad 1 is attached to the inner surface of the underwear with the adhesive of the back sheet 23 in a state where the underwear worn by the wearer is shifted downward (toe side). At this time, in the underwear, the front portion 110 is disposed at a position facing the wearer's male genital when worn, and the crotch lower end portion 12 is disposed at a position facing the wearer's crotch portion. And the light incontinence pad 1 is worn in a wearer by raising the said underwear upward with respect to a wearer, and also inserting the penis of a male genital into the opening part 35 (that is, attaching light incontinence pad 1) Underwear is worn.)

  In the absorbent core 22 of the light incontinence pad 1, a superabsorbent material layer 223 composed of a superabsorbent material 224 is provided between the upper layer sheet 221 and the lower layer sheet 222, and is used for water absorption in which pulp fibers and the like are gathered. A fiber assembly layer is not provided. Thereby, thickness reduction of the absorption core 22 can be achieved, and it can be made hard to understand that the said wearer is wearing the light incontinence pad 1 in the appearance of the wearer who wore clothing. Moreover, in a wearer, it can suppress that the discomfort by the light incontinence pad 1 arises around a male genitalia.

  Since both side portions of the front end portion 11 are regions where the absorbent core 22 is absent, the both side portions are prevented from becoming bulky or stiff, and the wearer can be lightly viewed. It can be made more difficult to understand that the incontinence pad 1 is worn. Further, as will be described later, even when the superabsorbent material 224 of the absorbent core 22 absorbs the urine excreted by the wearer and swells, the swollen absorbent core 22 into the lower abdomen of the wearer. The pressure caused by can be suppressed.

  In the light incontinence pad 1, one folding line F <b> 1 when accommodated in the packaging bag 91 is provided so as to intersect with the non-joining part 332 of the inner edge portion 33, and the main body 2 is connected to the back sheet 23 in the folding line F <b> 1. It is brazed so as to protrude to the side. Thereby, coupled with the contraction of the cover elastic member 36, the distance at which the non-joining portion 332 is separated from the main body portion 2 is increased, and the opening 35 is in a state of being largely opened. As a result, the wearer can easily insert the male genital into the opening 35. Moreover, in the state in which the wearer wears the light incontinence pad 1, the portion of the main body portion 2 that faces the wearer's male genitalia protrudes on the opposite side of the wearer. It is possible to further suppress the uncomfortable feeling caused by the light incontinence pad 1 around. In the light incontinence pad 1, the width of the crotch lower end portion 12 in the width direction is smaller than the width of the front end portion 11, thereby preventing the wearer from feeling uncomfortable due to the light incontinence pad 1 in the crotch portion. it can.

  When urine is excreted from the wearer's male genitalia, the urine is received in the front part 110 in principle, passes through the top sheet 21 and reaches the absorbent core 22. Urine is absorbed by the superabsorbent material 224 in the plurality of material existence regions 225, and the superabsorbent material 224 swells. At this time, since urine diffuses to some extent in the longitudinal direction through the material absence region 226, a wide range of superabsorbent material 224 in the front portion 110 can be used for urine absorption. Moreover, since the male genitalia is inserted into the opening 35, the excreted urine can be prevented from leaking out of the light incontinence pad 1. In the light incontinence pad 1, the penis of the male genitalia is held in the opening 35, so that the position of the penis is prevented from being shifted with respect to the light incontinence pad 1.

  After a certain amount of urine is excreted by the wearer and the superabsorbent material 224 of the front portion 110 swells, there is a groove extending in the longitudinal direction in the material absence region 226 between the material presence regions 225 adjacent to each other. It is formed. Thereafter, when the urine is further excreted by the wearer, the urine is efficiently diffused in the longitudinal direction (mainly toward the crotch lower end 12 side) through the groove, and a wide range of high absorption in the light incontinence pad 1 is achieved. The material 224 can be used for urine absorption (the same applies when a material low density region is provided). Further, even when a large amount of urine is excreted by a wearer (particularly, a seated or standing wearer) and it takes time to absorb all the urine by the absorbent core 22, the bag-like portion 34 having a relatively large internal space. By holding the urine at, the urine can be prevented from returning to the wearer.

  In the light incontinence pad 1, the width of the non-absorbable region 201 is maximized at a predetermined position between the front end portion 11 and the crotch lower end portion 12 in the longitudinal direction. Therefore, after the light incontinence pad 1 is used, the wearer (or caregiver) picks up the non-absorbable region 201 at the predetermined position (without picking up the absorbent core 22 and the absorbent paper 24 including urine). ), The light incontinence pad 1 can be easily removed from the underwear. In addition, by bending the non-absorbent region 201 toward the top sheet 21 along the side edge of the water absorbent paper 24, the non-absorbable region 201 can be used as a simple side wall portion.

  In the light incontinence pad 1, the water absorbent paper 24 can be omitted. In this case, the part of the absence region of the absorbent core 22 on both sides of the front end portion 11 is formed only by the cover sheet 31, the top sheet 21, and the back sheet 23. As a result, the rigidity of the part is lowered, and the part is bent unnecessarily, so that the wearer may feel uncomfortable.

  On the other hand, in the preferred light incontinence pad 1, the water absorbent paper 24 is provided between the absorbent core 22 and the back sheet 23, and a part of the water absorbent paper 24 is formed in the absence region of the absorbent core 22 on both sides of the front end portion 11. Overlap. Thereby, a certain amount of rigidity can be ensured in each side portion of the front end portion 11, and a state in which the front end portion 11 is appropriately expanded in the width direction can be maintained. As a result, it is possible to prevent the wearer from feeling uncomfortable due to the bending of the region in the region.

  The cover portion 3 in the light incontinence pad 1 of FIG. 1 can be easily manufactured using equipment related to manufacturing a so-called three-dimensional gather. FIG. 8 is a cross-sectional view showing a light incontinence pad 8 of a comparative example in which the cover 3 in the light incontinence pad 1 is changed to a pair of side sheets 81 forming a three-dimensional gather. In the light incontinence pad 8 of the comparative example, each side sheet 81 is bent along a folding line 82 extending over the entire length in the longitudinal direction. In the side seat 81, one side portion of the folding line 82 is a side wall fixing portion 83, and the other side portion is a side wall portion 84. The side wall fixing portion 83 corresponds to a part of the outer edge portion 32 of the light incontinence pad 1 and is joined to the side portion of the main body portion 2. The side wall portion 84 continues from the side wall fixing portion 83 at a folding line 82. At each end portion 841 of the side wall portion 84 in the longitudinal direction (hereinafter referred to as “side wall end portion 841”), the side wall portion 84 is folded in two and overlapped with the side wall fixing portion 83 and joined. The elastic member 85 is joined to the distal end portion of the side wall portion 84 in an extended state. When the elastic member 85 contracts, the side wall 84 rises from the main body 2 toward the wearer between both end portions (two side wall end portions 841) in the longitudinal direction to form a three-dimensional gather (see FIG. 8) (refer to the side wall portion 84 indicated by a two-dot chain line).

  On the other hand, in the light incontinence pad 1 in FIG. 2, the pair of side sheets 81 in the light incontinence pad 8 of the comparative example in FIG. 8 is handled as a pair of cover sheets 31. Bending is omitted. Further, the folding of the side wall 84 according to the formation of the side wall end 841 is also omitted, and the portion of the side wall 84 corresponding to the side wall end 841 is joined to the main body 2 in an extended state. As a result, the portions of the side wall fixing portion 83 and the side wall portion 84 become the outer edge portion 32. Furthermore, the front-end | tip part of the side wall part 84 becomes the inner edge part 33, and the junction part 331 is formed by joining the inner edge parts 33 in a pair of cover sheet 31 in the predetermined range in a longitudinal direction (refer FIG. 4). ). Thereby, the cover part 3 formed of a pair of cover sheets 31 is produced. As described above, the cover portion 3 of the light incontinence pad 1 in FIG. 1 can be produced by a simple change to the equipment related to the production of the three-dimensional gather, and the manufacture of the light incontinence pad 8 of the comparative example having the three-dimensional gather. 1 can be easily switched to the manufacture of the light incontinence pad 1 of FIG.

  The light incontinence pad 1 can be variously modified.

  As shown in FIG. 9, a folded portion may be provided in which the side edge of the nonwoven fabric constituting the cover sheet 31 is folded back to the wearer side. In this case, the tip of the folded portion is joined to the wearer-side surface of the nonwoven fabric. Moreover, the cover part elastic member 36 is arrange | positioned between the said folding | returning part and the opposing part which opposes the said folding | returning part. Thus, in the inner edge part 33 of each cover sheet 31, the edge of the nonwoven fabric which comprises the said cover sheet 31 is turned back to the opposite side (wearer side) from the top sheet 21, The edge of the said nonwoven fabric becomes It is possible to prevent stimulation of the penis of the male genitalia arranged in the opening 35 without being arranged in the space between the cover 3 and the main body 2.

  The light incontinence pad 1 may employ a design in which the cover elastic member 36 is omitted from the inner edge 33. However, in this case, the inner edge portions 33 of the pair of cover sheets 31 or the inner edge portion 33 and the main body portion 2 are easily maintained in contact with each other. However, it takes time and effort to widen the opening 35 by separating the non-joining portion 332 of the pair of cover sheets 31 from the main body portion 2. On the other hand, when the cover elastic member 36 is provided along the edge of the opening 35, the opening 35 naturally expands due to the shrinkage of the cover elastic member 36, and thus it is possible to eliminate the above trouble for the wearer. Become.

  As shown in FIG. 10, the cover part 3 may be formed of a single cover sheet 31a. The cover sheet 31a covers the entire wearer side surface of the main body 2 (the surface on the top sheet 21 side). Further, a slit extending in the width direction is formed as an opening 35 in a portion of the cover sheet 31 a on the front portion 110 side, and a cover elastic member 36 is provided along the edge of the opening 35. A bag-like portion 34 is formed between the cover sheet 31a and the main body 2 at the crotch portion 120 side. Also in the light incontinence pad 1 of FIG. 10, leakage of excreted urine out of the light incontinence pad 1 can be prevented by inserting a male genital into the opening 35. Moreover, even when a large amount of urine is excreted, the urine can be prevented from returning to the wearer side by being held by the bag-like portion 34. In the cover sheet 31a, an opening 35 extending in the longitudinal direction may be formed.

  As shown in FIG. 11, in the absorbent core 22, a region A <b> 1 where a plurality of absorbent sheets 220 are provided and a region A <b> 2 where a smaller number of absorbent sheets 220 than the region A <b> 1 are provided may be set. Preferably, the region A1 is provided in the front portion 110, and the region A2 is provided in the crotch portion 120. Thus, the manufacturing cost of the light incontinence pad 1 can be reduced by stacking more absorbent sheets 220 than other parts only in the front part 110 where a large amount of absorption is required.

  Depending on the design of the light incontinence pad 1, the absorbent core 22 may have a shape other than a rectangle. Further, depending on the amount of urine absorption required in the light incontinence pad 1, the absorption core 22 may be provided only in the front portion 110.

  In the absorbent sheet 220, the pattern of the material presence region 225 may be changed as appropriate. When the light incontinence pad 1 is not required to be thinned, the absorbent core 22 may include a water-absorbing fiber aggregate layer in which pulp fibers and the like are aggregated.

  The configurations in the above-described embodiments and modifications may be combined as appropriate as long as they do not contradict each other.
