  Hereinafter, embodiments will be described in detail with reference to the drawings. However, the constituent elements described in this embodiment are merely examples, and are not intended to limit the scope of the present invention only to them.

<1. First Embodiment>
FIG. 1 is a plan view showing the entire absorbent article 100 according to the first embodiment. The absorbent article 100 is configured as an auxiliary absorbent device such as a urine picking pad attached to the inner side (skin surface side) of a so-called disposable diaper or an outer body such as underwear, and attached to the wearer's crotch part. ing. FIG. 1 illustrates a state in which the inner surface side in contact with the wearer is viewed.

  In the following description, the wearer's abdomen side is defined as the front side and the back side is defined as the rear side with reference to the state where the absorbent article 100 is mounted. This front-rear direction corresponds to the longitudinal direction of the absorbent article 100 shown in FIG. 1, and the left-right direction orthogonal to the longitudinal direction corresponds to the width direction of the absorbent article 100.

  As shown in FIG. 1, the absorbent article 100 is installed on both sides in the width direction on the inner side (skin surface side) of the main body 2 and the pair of three-dimensional gathers 3 and 3 extending along the longitudinal direction. And. The pair of three-dimensional gathers 3 and 3 are provided with a gap in the center in the width direction of the main body 2. Although not shown, a fastening portion (surface fastener, adhesive tape, etc.) for attaching the absorbent article 100 to the exterior body is provided on the outer surface (opposite to the skin surface side) of the main body 2. It has been.

  The main body 2 has a shape in which both sides are constricted inward in the vicinity of the center in the longitudinal direction. When the wearer wears the absorbent article 100, the constricted portion is disposed on the crotch, and both side portions thereof extend around the legs. In addition, the shape of the main-body part 2 is not restricted to such a thing, It can change suitably.

  FIG. 2 is a schematic cross-sectional view of the absorbent article 100 cut along a plane perpendicular to both the longitudinal direction and the width direction at the position II-II shown in FIG. The main body 2 includes a substantially flat absorbent body 21, a top sheet 22 that covers an inner main surface that is the skin surface side of the absorber 21, and an outer main body that is opposite to the skin surface side of the absorbent body 21. It is a laminate composed of a back sheet 23 covering the surface. Although not shown, the absorber 21, the top sheet 22, and the back sheet 23 are bonded to each other via a hot melt adhesive or the like. Further, a liquid collection container (specifically, a urine collection container) 24 is disposed together with the absorber 21 in the internal space 2S of the main body 2 formed by the top sheet 22 and the back sheet 23.

  The absorbent body 21 is made of, for example, an absorbent element composed of hydrophilic fibers such as pulverized pulp fiber or cellulose fiber, a water-absorbing polymer formed in a granular form (for example, SAP (Super Absorbent Polymer)), or a mixture thereof. It is formed so as to be covered and wrapped with a liquid-permeable sheet-like member such as tissue. The absorber 21 quickly absorbs and holds the body fluid that has passed through the top sheet 22. The absorbent element constituting the absorbent body 21 is bonded to the sheet-like member via, for example, a hot melt adhesive.

  The top sheet 22 is made of, for example, a nonwoven fabric that is made liquid-permeable by treating the surface of hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.) with a surfactant. However, the top sheet 22 may be composed of a nonwoven fabric using hydrophilic fibers (cellulose, rayon, cotton, etc.), or a plastic film in which holes to the extent that body fluid such as urine can permeate are formed. Or the like.

  The back sheet 23 is made of, for example, a plastic film on which a plastic film or a highly flexible nonwoven fabric is stuck. However, the back sheet 23 may be made of a water-repellent nonwoven fabric using hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.).

  The liquid recovery container 24 includes a container body 241 having a substantially cylindrical shape that is a hollow cup shape having an opening 24a formed on the upper side, and a cover sheet 242 that covers the opening 24a. The liquid collection container 24 stores the urine excreted by the wearer inside the container body 241 through the opening 24a. As shown in FIG. 2, the liquid collection container 24 is arranged so that the opening 24a opens toward the top sheet 22 (that is, the skin surface side), so that the excreted urine enters the liquid collection container. It becomes easy and urine can be collected well.

  As shown in FIG. 2, a recess 211 having a size corresponding to the liquid recovery container 24 is formed on the outer main surface of the absorber 21. The liquid recovery container 24 is positioned by aligning the top of the opening 24a of the liquid recovery container 24 with the recess 211. Although the capacity | capacitance of the liquid collection | recovery container 24 shall be about 4-5 milliliters, for example, a magnitude | size is not limited to this. However, the liquid recovery container 24 can be stored in the internal space 2S, and has a capacity that can secure the minimum necessary urine.

  The liquid recovery container 24 is made of soft plastic (ethylene-vinyl acetate copolymer (EVA), soft polyethylene, polybutene, etc.) or rubber (natural rubber, synthetic rubber). By configuring the liquid recovery container 24 with such a relatively easily deformable material, the wearer's skin can be prevented from being damaged, and the absorbent article 100 can be comfortably worn. Further, by installing the liquid collection container 24 outside the absorbent body 21, the absorbent body 21 can also function as a cushioning material that softens the contact of the liquid collection container 24 with the skin, so that the feeling of discomfort at the time of wearing is reduced and comfort is provided. Will improve.

  The urine immediately after being excreted from the urination port of the wearer once passes through the absorber 21 and moves toward the liquid collecting container 24 on the opposite side with the excreted momentum. Here, since the absorber 21 is thinly formed in the recess 211, urine can easily pass through this portion. A part of the moved urine is collected in the liquid collection container 24. Since the opening 24 a of the liquid recovery container 24 is formed on the skin surface side of the container main body 241, urine is efficiently stored inside the container main body 241. Urine that has not been collected in the liquid collection container 24 is appropriately absorbed by the absorber 21.

  As shown in FIG. 1, the liquid recovery container 24 is installed at the center in the width direction and the center in the longitudinal direction of the main body 2. The absorbent article 100 according to the present embodiment is configured for women, and the vicinity of the central portion in the longitudinal direction is the urination opening of the wearer when the absorbent article 100 is attached to the crotch of the wearer. It corresponds to the position (urination point). Therefore, since the liquid collection container 24 can receive the urine discharged from the urination port by the wearer in the vicinity thereof, the urine can be efficiently stored. When the absorbent article 100 is configured for men, the urination port slightly approaches the ventral side, and the position of the liquid recovery container 24 may be moved accordingly. However, the position where the liquid collection container 24 is installed does not necessarily have to be matched with the urination point, and can be freely set as appropriate.

  As shown in FIG. 2, a liquid absorbing element 243 made of sponge, pulp, or a mixture thereof is accommodated in the container main body 241. Such a liquid absorption element 243 can appropriately hold the absorbed body fluid. For example, when a polymer absorbent is used as the liquid absorbent element 243, it is necessary to take out urine from the polymer absorbent by osmotic pressure using salts or the like. On the other hand, when sponges or pulps are used as the liquid absorbing element 243, urine can be collected with almost no influence on the components by simply applying pressure, which is suitable for urinalysis.

  The cover sheet 242 that covers the opening 24 a is formed of a liquid-permeable sheet, similar to the top sheet 22. The cover sheet 242 is attached to the container main body 241 via a hot melt adhesive or the like. By attaching such a cover sheet 242, it is possible to prevent foreign matters such as dust from entering the liquid collection container 24 from the outside, and thus it is possible to perform a good inspection with the collected urine. Moreover, since the opening part 24a is covered with the cover sheet 242, it can reduce that the accommodated bodily fluid flows out through the opening part 24a.

  FIG. 3 is a perspective view when the cross section of the liquid recovery container 24 cut along a plane perpendicular to the longitudinal direction is viewed from below. As shown in FIG. 3, a projecting portion 241 b projecting inward from the side wall portion 241 a constituting the circumferential surface is provided around the opening 24 a of the container main body 241. The opening 24a is formed by the edge of the inner end of the overhang 241b. That is, the opening area of the opening 24 a is smaller than the opening area inside the container main body 241 of the liquid recovery container 24 (opening area of the container cross section). The overhang portion 241b can function as a return member when urine in the container main body portion 241 is about to leak through the opening portion 24a. Therefore, it is possible to reduce leakage of urine stored in the container main body 241 from the opening 24a.

  FIG. 4 is a plan view of the absorbent article 100 as viewed from the back sheet 23 side. As shown in FIG. 4, a take-out port forming portion 231 for forming a take-out port for the liquid recovery container 24 is provided in the vicinity of the portion of the back sheet 23 where the liquid recovery container 24 is provided.

  The extraction port forming portion 231 has a fragile portion 232 formed thinner than the peripheral portion by forming a so-called perforation provided with a plurality of holes in a broken line shape. Each hole of the perforation is sized so that excreted urine does not leak to the outside. The fragile portion 232 is provided so as to extend linearly along a predetermined direction (the front-rear direction in the present embodiment). Thereby, since the weak part 232 becomes easy to fracture | rupture linearly, a taking-out port can be formed comparatively easily. Although illustration is omitted, the visibility of the fragile portion 232 is improved by attaching a mark in the vicinity of the fragile portion 232 by various marking means such as a figure (such as an arrow), character printing, or coloring.

  The method of providing the fragile portion 232 is not limited to a perforation. For example, a linear notch (slit) or the like may be formed in the back sheet 23 in advance, and the notch may be easily broken than the peripheral portion by adhering and closing the notch with hot melt or the like. .

  In order to smoothly remove the liquid recovery container 24 from the internal space 2S, it is only necessary to form an extraction port that opens to such an extent that the liquid recovery container 24 can easily pass through without being caught. Therefore, for example, as shown in FIG. 4, by making the length of the fragile portion 232 longer than the width of the liquid recovery container 24, it is possible to easily form a takeout port through which the liquid recovery container 24 can be smoothly taken out.

  Returning to FIG. 2, the three-dimensional gathers 3 and 3 are joined to the top sheet 22 by a hot melt adhesive or the like. The three-dimensional gathers 3, 3 are formed by bending the side sheets 31, 31 inside as shown in FIG. The elastic member 32 is attached to each inner side of the bent portion in a state where the elastic member 32 is extended from the natural length along the longitudinal direction. By the expansion and contraction action of the elastic member 32, the three-dimensional gathers 3 and 3 stand up inward so as to be pressed against the wearer's skin side.

  The side sheet 31 is formed of a water-repellent or liquid-impervious nonwoven fabric (such as a spunbond nonwoven fabric), a plastic film, or a composite material thereof. In addition, from the viewpoint of making the absorbent article 100 comfortable to wear, the side seat 31 is preferably made of a highly breathable material. The elastic member 32 is made of a synthetic rubber (polyurethane or the like), natural rubber, or the like formed in a thread shape or an elongated sheet shape.

  The pair of three-dimensional gathers 3 and 3 are not necessarily provided so as to be parallel to each other along the front-rear direction, and need only extend with at least a component in the longitudinal direction. However, when standing, it is desirable to have a shape corresponding to the buttocks so that it can be fitted to the buttocks of the body.

  As described above, in the absorbent article 100 according to the present embodiment, since the liquid collection container 24 is stored in the internal space 2S, it is not necessary to expose the urine collection part to the outside of the main body 2. Therefore, the absorbent article 100 can be configured more compact than the conventional product. Thereby, since the bulk when the absorbent article 100 is mounted on an outer package such as a disposable diaper or underwear can be reduced, the wearer can comfortably wear the absorbent article 100 from which urine collection is easy. Become.

  Further, since the volume of the urine storage bag described in Patent Document 1 is very large, it is not suitable for use for storing a small amount (for example, several milliliters) of urine for the purpose of, for example, urinalysis. On the other hand, the urine absorbent article 100 of the present embodiment is suitable for collecting urine for the purpose of examination and the like because an appropriate amount of urine can be secured by the urine collecting container 24.

  The liquid absorbing element 243 may not necessarily be stored in the urine collection container 24. In this case, since urine is stored as it is in the urine collection container 24, after removing the urine collection container 24, an appropriate test paper is inserted into the opening 24a and immersed in urine to immediately carry out a urine test. Is possible. Of course, it is not impeded to collect urine from the urine collection container 24 with a dropper or pipette.

<2. Second Embodiment>
In the first embodiment, the absorbent article 100 is provided with the recess 211, and the liquid recovery container 24 is positioned by fitting the recess 211 therein. However, the installation method of the liquid recovery container 24 is as follows. It is not limited to such a thing. In the following description, elements having the same functions as those in the first embodiment are appropriately denoted by the same reference numerals and description thereof is omitted.

  FIG. 5 is a schematic cross-sectional view of the absorbent article 100 according to the second embodiment. 5 corresponds to the position II-II shown in FIG.

  The absorbent article 100 according to the present embodiment includes an absorbent body 21A in which a through hole 211A having a size corresponding to the width direction of the liquid recovery container 24 is formed instead of the absorbent body 21 provided with the recess 211. Yes. By inserting the liquid recovery container 24 into the through hole 211A, the liquid recovery container 24 is positioned at a predetermined position.

  Even when the absorbent article 100 is configured as in the present embodiment, the liquid recovery container 24 is housed in the internal space 2S of the main body 2 so that the urine can be easily recovered as in the first embodiment. The product 100 can be formed compactly. When the liquid collection container 24 is arranged in this way, the excreted urine can enter the opening 24a without going through the absorber 21A. Therefore, the urine collection efficiency is higher than that in the first embodiment. improves.

<3. Third Embodiment>
In the above embodiment, the fragile portion 232 is formed so that the back sheet 23 is easily broken, so that the extraction port of the liquid recovery container 24 is formed. It is not limited.

  FIG. 6 is a schematic perspective view showing a take-out port forming portion 231A according to the third embodiment. In FIG. 6, the take-out port forming portion 231A viewed from the back sheet 23 side is illustrated.

  The take-out port forming portion 231A includes a seal member 233 that covers the opening (take-out port 23a) provided in advance in the back sheet 23 so as to block all of the openings. The seal member 233 is made of a liquid-impervious material such as a plastic film like the back sheet 23 and is bonded to the back sheet 23 via an adhesive.

  In the present embodiment, when the liquid collection container 24 is taken out from the used absorbent article 100, the takeout port 23a is formed by peeling the seal member 233 from the back sheet 23. Since the takeout port 23a can be easily exposed in this manner, the liquid collection container 24 can be taken out easily. The seal member 233 may be configured to be able to be completely peeled off from the back sheet 23, but may be fixed so that a part thereof remains on the back sheet 23. By comprising in this way, it becomes easy to discard the sealing member 233 with the main-body part 2. FIG.

<4. Fourth Embodiment>
As shown in FIGS. 2 and 3, the liquid recovery container 24 according to the above embodiment has a shape that is relatively flat and has wide upper and lower surfaces. However, the liquid recovery container is limited to such a shape. is not.

  FIG. 7 is a perspective view of a liquid recovery container 24A according to the fourth embodiment. The liquid recovery container 24A has an elongated shape (bar shape) extending in a predetermined direction, and is configured by a hollow member having a hollow inside. As shown in FIG. 7, the liquid recovery container 24A has an elongated outer peripheral surface 244, and a plurality of openings 24aA are formed on the outer peripheral surface 244. Although not shown, the liquid absorbing element 243 is stored in advance in the hollow member of the liquid recovery container 24A as in the first embodiment.

  The liquid recovery container 24A of the present embodiment can be disposed at the same position as the liquid recovery container 24 in the main body 2 according to the first embodiment. However, in order to ensure comfort when the absorbent article 100 is mounted, the liquid recovery container 24A is disposed near the center in the width direction of the main body 2, and the extending direction of the liquid recovery container 24A is the absorbent article 100. It is desirable to arrange it along the longitudinal direction. By arranging in this way, when the absorbent article 100 is mounted, the liquid collection container 24A is arranged so as to extend along the front and rear in the wearer's crotch, so that a sense of incongruity due to contact with the skin is reduced. Can be done.

  Further, when the liquid recovery container 24A is arranged in the internal space 2S, the urine recovery efficiency is improved by installing the liquid recovery container 24A so that a part or all of the plurality of openings 24aA open toward the skin surface side.

  The material constituting the liquid recovery container 24A is not particularly limited. However, for example, when the outer peripheral surface 244 of the liquid recovery container 24A is formed thin in order to secure a large capacity with a small size, it is made of a relatively hard plastic (polystyrene, acrylic resin, etc.). This makes it difficult for the liquid recovery container 24A having an elongated shape to be deformed. Thereby, it can suppress that the urine accommodated in the container leaks from opening part 24aA.

  Also, instead of providing a plurality of openings 24aA, a single opening may be provided as in the first embodiment. In this case, it is desirable to provide a hole that is somewhat large in order to improve the urine collection efficiency. When such a large-sized opening is provided, it is desirable to cover the opening with a cover sheet 242 in order to suppress leakage of urine and contamination with foreign matter.

  As described above, even when the liquid recovery container 24A according to the present embodiment is employed, the urine can be easily recovered by disposing the liquid recovery container 24A in the internal space of the main body 2 as in the above embodiment. It is possible to form the absorbent article 100 compactly.
