Description

  The present invention relates to an absorbent product capable of retaining manure.

For absorbent products for conventional incontinence and infants, pants that have the same shape as pants and tape-type disposable diapers that are assembled into pants with tape, or placed in pants There are urine picking pads used.
Patent Document 1 is an example of this diaper. As shown in FIG. 5, a top sheet 13 in which a liquid-permeable non-woven fabric or the like is arranged on the crotch side of a user, and excrement permeate outside. And an absorbent body 14 made of an absorptive polymer or the like that absorbs excretion that has passed through the top sheet 13 and is sandwiched between the top sheet 13 and the back sheet 12.

  In the diaper of this patent document 1, when the excrement is loose stool or the like, even if the absorbent body 14 cannot quickly absorb and absorb it, the loose stool or the like is prevented from adhering to the wearer's skin. We are trying to prevent troubles. Specifically, it has a skin contact sheet 23 that does not hang down due to the force of the elastic members 20, 21 when attached, and a gap 24 is formed between the skin contact sheet 23 and the top sheet 13. Yes. An opening 29 having a predetermined size is formed in the skin contact sheet 23 corresponding to the anus, and loose stool or the like passes through the opening 29 and falls into the gap 24. Yes.

JP 2002-204811 A

By the way, in the diaper of Patent Document 1, soft stool or the like can be dropped from the opening 29 of the skin contact sheet 23 into the gap 24.
However, when a man wears it, urination is performed on the skin contact sheet 23, so that it is difficult to quickly move it to the absorber 14. In particular, in Patent Document 1, since there is a gap 24 between the skin contact sheet 23 and the absorbent body 14, it is difficult for urine placed on the skin contact sheet 23 to move to the absorbent body 14. For this reason, the result is that the wearer's skin is soiled with urine.
In the case of men, a pad that wraps the penis is sold separately, and if this is used, the problem of urine is eliminated. However, when such a pad is used, the gap 24 is crushed and loose stool or the like is put into the gap 24. Can be difficult.
In this regard, if a hole for inserting a penis is formed in the skin contact sheet 23 separately from the opening 29, the penis can be inserted between the skin contact sheet 23 and the absorbent body 14. However, in such a form, not only are the holes unnecessary for use by women, but also loose stool or the like that breaks out from the opening 29 leaks from the penis insertion hole to the skin side, and the woman's skin There is a risk of loose stool sticking to the skin.
Therefore, an object of the present invention is to provide an absorptive product capable of serving both men and women while avoiding as much as possible excrement touching the body.

The subject is mounted between at least the lower abdomen and the anus of the wearer, the waterproof sheet prevents passage of the excrement of the wearer, and is disposed closer to the wearer than the waterproof sheet. An absorbent body that absorbs and retains, and a sheet body that is arranged on the most wearer side and is made of a nonwoven fabric, and the sheet body has a fiber orientation in the front-rear direction connecting the lower abdomen and the anus And having an elastic member that exerts an elastic force so as to be separated from the absorber at least in a region from the crotch portion to the anus portion when worn, and at least loose stool of the excrement to the absorber side And a perforation formed by intermittently arranging a plurality of cuts along substantially the left-right direction of the male at a position corresponding to the base of the penis when the male is worn. Made which are, the perforations may have a row of first and second perforations adjacent to one another in the longitudinal direction, the first perforation row and the second perforation row A This is solved by an absorbent product in which the positions of the cuts are formed alternately in the left-right direction .

According to the present invention, a waterproof sheet that is mounted between at least the lower abdomen and the anus of the wearer and prevents the wearer's excrement from passing through, and is disposed closer to the wearer than the tarpaulin and absorbs excrement. And an absorbent body to be held. Therefore, if the excrement can be moved to the absorber, the excrement can be held by the absorber and can be prevented from adhering to the clothing side by the waterproof sheet.
In this regard, the sheet body closest to the wearer has an elastic member that exerts an elastic force so as to be separated from the absorbent body in the region from the crotch portion to the anus portion when worn. A space can be formed between the sheet body and the absorber in the region.
And since the sheet | seat body has the passage means for letting at least the loose stool of excrement pass to the absorber side, it can move at least a soft stool from the passage means to the absorber side. At this time, since a space is positively formed by the action of the elastic member between the sheet body and the absorbent body, soft stool or the like is accommodated in the space and then absorbed by the absorbent body. In the meantime, it is possible to suppress the situation where the stool or the like and the skin are partitioned by the sheet body to contaminate the wearer's skin.
Moreover, perforations formed by intermittently arranging a plurality of cuts along the substantially left-right direction of the male are formed at positions corresponding to the base of the penis when the male is wearing the sheet. For this reason, when a man wears, it can tear at the perforation of this sheet | seat body, and can insert a penis between a sheet | seat body and an absorber. Therefore, even if urine is excreted from the penis, it can be absorbed by the absorber.
In addition, when a woman uses it, if the perforation is not torn, there is no opening, so that loose stool or the like that has entered from the passage means leaks out from the perforation to the skin as much as possible. Can be prevented.

In addition , since the sheet body made of nonwoven fabric has fiber orientation in the front-rear direction connecting the lower abdomen and the anus, urine can be guided in the front-rear direction by capillary action, and the width of the crotch is narrow in the left-right direction It is possible to effectively prevent urine from leaking from the end.
In this respect, if there is fiber orientation in the front-rear direction connecting the lower abdomen and the anus, there is almost no stretch in the front-rear direction, while the wearer has a predetermined stretch in the left-right direction. If it does so, the row | line | column of the perforation formed along the substantially left-right direction for penis insertion will become difficult to tear by the elastic property of the left-right direction. If this is forcibly cut, there is a risk that the front-rear direction will be torn apart carelessly.
However, in the configuration of the present invention, the perforation has a row of first and second perforations adjacent to each other in the front-rear direction, and the row of the first perforation and the row of the second perforation Are formed with staggered incisions in the left-right direction. For this reason, since there is almost no elasticity in the front-back direction between the edge part of the 1st perforation and the edge part of the 2nd perforation adjacent to this, it is comparatively easy to tear. Accordingly, it is possible to form a cut for inserting the penis along the left-right direction as a whole while tearing between the first perforation and the second perforation.

Preferably, the passage means is a plurality of slits or long holes arranged in the region corresponding to the anus, the female external urethral orifice, and the periphery thereof.
Then, the passage means is in the area corresponding to the anus and its periphery, and the position of the anus in men and women does not change so much, so both men and women can quickly absorb loose stool etc. It can be moved to the body side.
And since it has a plurality of slits or long holes in the region corresponding to the outer urethral mouth of the woman and the periphery thereof, when the wearer is female and urinates, from the slit or long hole around the mouth of the outer urethra Urine can be moved to the absorber side.
Furthermore, when the wearer is a man, the perforation is torn as described above, and the penis is inserted between the sheet body and the absorbent body to urinate, but in that case, the urine jumps, etc. However, since the passage means is a slit or a long hole and has a narrow width, the opportunity for urine to touch the skin can be avoided as much as possible.
The “long hole” is a long hole having a narrow width, and is not limited to a straight hole, for example, a bent hole, a narrow oval / elliptical / triangular hole, etc. Is also included.

Preferably, the elastic member is connected to the sheet body in an extended state and is disposed along the front-rear direction connecting the lower abdominal part and the crotch part at the center part in the left-right direction when attached. It is characterized by being.
Then, with such an elastic member, when the seat body is worn, the center portion of the wearer in the left-right direction is convex upward, so that the seat body can be easily worn along a shape like an inverted U-shape of the crotch portion. It can be more closely attached to the wearer's skin. Therefore, it is possible to effectively prevent a situation in which excrement enters between the sheet body and the crotch portion and soils the wearer's skin. In addition, the space between the sheet body and the absorbent body is the largest space in the center of the wearer in the left-right direction, making it easier to insert the penis.
The above-mentioned “elastic member” is disposed at the center in the left-right direction of the wearer, but is not necessarily disposed directly below the anus or the outer urethral mouth, and is adjacent to the anus or the outer urethra. Are also included.

  As described above, the present invention can provide an absorptive product capable of serving both men and women while avoiding as much as possible excrement touching the body.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
The embodiment described below is a preferred specific example of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.
Moreover, in the following drawings, the parts denoted by the same reference numerals have the same configuration.
In the following description, unless otherwise specified, “front-back direction” refers to the direction connecting the lower abdomen, crotch, and buttocks of the wearer when the absorbent product is worn, and “left-right direction” refers to absorbability. It means the wearer's left and right direction when wearing the product (the direction connecting the right leg and the left leg).

[First Embodiment]
First, the absorbent product 10 which concerns on 1st Embodiment of this invention is demonstrated using FIGS. FIG. 1 shows a state of being bent by an elastic member 28 described later, and FIG. 2 is a plan view of the absorbent product 10 shown in FIG. In FIG. 3B, the pants are omitted. 4 is an enlarged view around the elastic member 28.
Although the absorbent product 10 of FIGS. 1-9 has shown the example of the urine picking pad for incontinence (it is also called "the incontinence pad") laid and used in underpants as a suitable example of this invention. The absorbent product of the present invention is not limited to incontinence but can also be used as a baby diaper. Moreover, it can be used not only in the form of laying in the pants, but also in disposable diapers such as a pants type in which the diaper itself has a pant shape, or a tape type that is assembled and used in the shape of the pants with a tape.

As shown in FIGS. 1 and 2, when the absorbent product 10 is expanded, the absorbent product 10 is generally flat and has a shape like a bag, and is long in one direction (Y direction in the figure). This longitudinal direction Y is along the wearer's front-rear direction, and is attached to the buttocks side from the wearer's lower abdomen side through the crotch part, and both end portions 10a, 10b in the longitudinal direction Y are shown in FIG. The pants 2 are arranged up to the waist of the wearer US or a position close to the girth of the wearer US and fixed to the pants 2 with an adhesive or the like. The absorbent product 10 is generally bowl-shaped and fits the wearer, and is disposed at a predetermined position without a fixing means such as an adhesive. The absorbent product 10 may be appropriately provided with a fixing means to the pants 2 according to the overall shape.
Moreover, the width direction (short direction) X orthogonal to this longitudinal direction Y is mounted | worn along a wearer's left-right direction.
As shown in FIG. 2, the reduced width portion 12 is formed in the absorbent product 10 by shortening the dimension in the width direction X in the vicinity of the central portion in the longitudinal direction Y. The reduced width portion 12 is a portion attached to the crotch portion.
The reduced width portion 12 is not at the center in the longitudinal direction Y, but is slightly shifted in position, and the distance L1 from the reduced width portion 12 to the end portion 10b on the buttocks side is the end portion 10a on the lower abdomen side. Longer than the distance L2. The shape from the reduced width portion 12 to the end portion 10b on the heel portion side and the shape from the reduced width portion 12 to the end portion 10a on the lower abdomen side are each generally circular. In addition, about the width direction X, the absorptive product 10 is left-right symmetric.

  The absorbent product 10 shown in FIG.1 and FIG.2 has a pair of side gathers 14 and 14 which stand on the skin side along the longitudinal direction Y. FIG. The side gathers 14 are standing portions for preventing so-called side leakage from which excrement leaks from the width direction X. Specifically, as shown in FIG. 1 and FIG. 4, along the longitudinal direction Y, the free end portion 15 a of the waterproof side sheet 15 connected to both ends in the width direction X of the absorbent product 10. The elastic material 16 such as synthetic rubber is connected in an extended state. The dimension between the pair of side gathers 14 and 14 corresponds to the dimension in the lateral direction of the crotch portion. When the absorbent product 10 is attached, the side seat 15 is erected by the force of the elastic material 16 and is free. The end 15a hits between the crotch and the vicinity of the base of the inner thigh, so-called side leakage can be prevented.

As shown in FIG. 4, such an absorbent product 10 is composed of a plurality of layers, a waterproof sheet 18 exposed on the outside (pants side), and a wearer US side (skin side) rather than the waterproof sheet 18. The absorbent body 19 and the sheet body 20 arranged closest to the wearer US are included.
The waterproof sheet 18 is a member for preventing the excrement of the wearer US from passing through and preventing dirt on clothes, and is also called a back sheet. A known material can be used for the waterproof sheet 18 and is made of a flexible material, for example, a thin plastic film. Specifically, the waterproof sheet 18 may be a polyethylene film, polyethylene laminated paper, or the like. Preferably, a water-permeable but moisture-permeable material such as a microporous waterproof resin film may be used.

The absorber 19 is a member that absorbs and holds excrement, and is polymerized by being attached to the waterproof sheet 18 with hot melt or the like. It is preferable that the absorbent body 19 has a high retention property of the absorbed liquid and is relatively thin and not bulky. As such an absorber 19, for example, a pulp absorber formed by mixing a polymer that is an absorbent material with pulp, or spraying a polymer with pulp, and a polymer between the sheet materials made of pulp or the like with high density. A polymer sheet or the like arranged in a sheet shape can be used.
The absorber 19 is wrapped in a tissue 17 and is prevented from being exposed to the outside. The tissue 17 is formed into a sheet by combining a soft material that absorbs liquid, such as pulp, rayon, cotton, kenaf, bagasse, silk, hydrophilic fibers (polyolefin, polyester, acrylic), etc. Things can be used. In the case of forming a sheet, it is preferable that the surface is embossed and the liquid is diffused on the surface to absorb the liquid in a wide area of the absorber 19.

The sheet body 20 has a sheet shape, and forms a required space S between the skin of the wearer US and the absorbent body 19 and serves to spatially separate the space S and the skin of the wearer US. Have.
The sheet body 20 of this embodiment is formed from a nonwoven fabric. Known nonwoven fabrics can be used. For example, heat-bondable fibers (for example, PET / PE, PP / PE, PET / EP, PP / EP) obtained by fiberizing a synthetic resin are used for the thermal bond method or the spun bond method. It is formed by fusing without using a binder. Since such a nonwoven fabric is a material that is difficult to raise, it can be suitably used as a material that touches the user's skin, and can allow the excrement to permeate the absorbent body 19 side. This nonwoven fabric has liquid permeability and liquid permeability.

As shown in FIG. 3B and FIG. 4, the peripheral portion of such a sheet body 20 is connected to the absorber 19, but the region excluding the peripheral portion is not connected to the absorber 19. And the sheet | seat body 20 is an area | region from at least a crotch part to an anus part (at least the area | region from the position corresponding to the female external urethra HR shown to FIG. 3 (B) to the anus AN, and its periphery) , An elastic member 28 that exerts an elastic force so as to be separated from the absorber 19 is provided. Thereby, as shown in FIG.3 and FIG.4, the required space S can be positively formed between the sheet | seat body 20 and the absorber 19. FIG.
As shown in FIGS. 1 and 4, the sheet body 20 has passage means 25 for passing at least soft stool through the absorber 19, that is, the space S. Therefore, the loose stool excreted by the wearer moves to the space S through the passage means 25 formed in the sheet body 20, and after the soft stool is accommodated in the space S, it is absorbed by the absorber 20. In the meantime, the loose stool and the skin are separated by the sheet body 20, and even the soft stool that cannot be quickly absorbed by the absorbent body 19 can suppress the situation of soiling the wearer's skin. As will be described later, the passage means 25 of the present embodiment can move not only soft stool but also urine to the space S side, and can move to the space S side unless the stool is large and hard.

The absorbent product 10 of the present embodiment has the above characteristics, and further has a characteristic elastic member 28, a passing means 25, and a perforation 64.
First, the elastic member 28 will be described.
The elastic member 28 of this embodiment is connected to the sheet body 20 in an extended state as shown in FIGS. 1 to 4, and is attached to the wearer in the front-rear direction at the center of the wearer in the left-right direction. Arranged along.
That is, in the state of FIG. 2 in which the absorbent product 10 is stretched and expanded, the elastic member 28 is stretched along the longitudinal direction Y in the central portion in the width direction X and connected to the sheet body 20. In the state, an elastic force is exerted in the longitudinal direction Y. For this reason, as shown in FIG. 3B, when the absorbent product 10 is shaped along a curve connecting the lower abdomen, the crotch part, and the buttock, the elastic member 28 is contracted and the elastic member 28 is connected. In the sheet body 20, the state where the center portion in the left-right direction is convex upward as shown in FIG. 4 continues in the front-rear direction as shown in FIG. It becomes easy to wear along and can be made to adhere more closely to a wearer's skin.

Specifically, as shown in FIGS. 3 and 4, the sheet body 20 includes a skin side sheet body 26 made of a skin-side nonwoven fabric and an outer sheet body 27 made of a nonwoven fabric on the absorber 19 side, An elastic member 28 such as a synthetic rubber is sandwiched between the skin side sheet body 26 and the outer sheet body 27, and the skin side sheet body 26, the elastic member 28, and the outer sheet body 27 are fixed to each other by being adhered to each other. Yes.
A known elastic material such as a synthetic rubber can be used for the elastic member 28. However, when the thin sheet 20 touches the skin, a thin belt-like synthetic rubber (for example, heat It is preferable to use a polyurethane elastomer tape made of a plastic polyurethane tape.
In the present embodiment, when the elastic member 28 of FIGS. 1 and 4 is contracted, the gathers 29 are formed in the vicinity of the elastic member 28 of the sheet body 20 (the left and right side portions of the elastic member 28 of FIG. 4). The surface of the sheet body 20 is uneven. Thereby, even if the vicinity of the elastic member 28 is wet, a feeling of wearing can be improved.
Further, the elastic member 28 of the present embodiment has a lower side of the buttocks through the crotch portion and the anal portion from the lower abdomen as shown in FIG. 3 so that the largest possible space S can be formed. It is arranged until.
The outer sheet body 27 preferably has a higher fiber density than the skin side sheet body 26, whereby the liquid is positively guided to the outer sheet body 27 by capillary action and the liquid skin side sheet body 26. Can be suppressed.

Next, the passage means 25 will be described with reference to FIGS. 1, 2, and 4 described above and FIG. 5 showing a use state.
The passage means 25 has a plurality of slits and / or long holes arranged around the elastic member 28, and the passage means 25 of the present embodiment comprises the slits 3 as shown in FIG. The “periphery of the elastic member 28” means a region that receives the action of the elastic member 28.
Specifically, in the state of FIG. 2 in which the absorbent product 10 is stretched and spread, the slit 3 is completely closed. In the manufacturing process, the slit 3 is formed by inserting a cutter from above the sheet body 20 stretched and spread against the elastic force of the elastic member 28. On the other hand, in the curved state of FIG. 1, since the longitudinal direction Y contracts around the elastic member 28 of the sheet member 20 due to the elastic force of the elastic member 28, the width of the slit 3 is slightly expanded. That is, the slit 3 is opened.

As shown in FIG. 2, such a plurality of slits 3 are intermittently arranged along the longitudinal direction to form a row, and this row is arranged in the width direction X to form a plurality of rows G1 to G6. ing. In the present invention, the number of rows is not limited to the number in FIG. 2, but it is preferable that the right and left sides are similar to each other around the elastic member 28 in the width direction X. In this case, the right three rows G1 to G3 and the left three rows G4 to G6 have the same configuration.
The rows G3 and G4 closest to the center in the width direction X are arranged on the left and right sides of the anus adjacent to the wearer's anus when worn. The elastic member 28 is disposed between the rows G3 and G4 with a slight gap W1 from both sides of G4 (the gathers 29 in FIG. 4 are formed on the sheet body 20 in the region of the gap W1). ) Therefore, as shown in FIG. 4, the elastic member 28 is disposed almost immediately below the anus, and the sheet body 20 fits into the cracks of the buttocks and the like, and excrement is placed between the sheet body 20 and the absorber 19. A large space S for entering can be formed.
In addition, it is preferable that the elastic member is not arranged adjacent to the left and right sides of the rows G3 and G4 arranged on the most central side.

In this regard, as shown in FIG. 2, in the relationship between the adjacent columns G1 to G6, the slits 3 are shifted from each other in the longitudinal direction Y so that the phases are shifted. As a result, when excrement flows in the width direction X, even if loose stool is transmitted between the plurality of slits 3 intermittently arranged in the central row (for example, G3, G4), the outer row thereof A plurality of slits 3 (for example, G2 and G5) intermittently arranged so as to catch soft stool. Further, there is a standard for how to shift this position, and the boundary between the wearer's buttocks and inner thighs, And / or, at the boundary between the buttocks and the inner thighs (for example, the boundary between the buttocks HP and the inner thigh TH in FIG. 3), the slits 3 are arranged in a plurality of rows G1 to G6 along the boundary. The position in the longitudinal direction Y of the slits 3 of the rows G1 to G6 is determined with reference to the arrangement of the slits 3 at the boundary. That is, taking FIG. 2 as an example, the arrangement (arrangement direction R1) of the plurality of slits 3a, 3b, 3c in each row arranged in the width direction X is the direction R2 of the boundary between the hip HP and the inner thigh TH in FIG. The slits 3 of the rows G1 to G6 are regularly arranged along the longitudinal direction Y with reference to the arrangement of the slits 3a, 3b, 3c in FIG. Thus, for example, even when soft stool or urine flows along the boundary between the hip HP and the inner thigh TH in FIG. 3 (along the direction of the arrow R2), the slit at the boundary (slits 3a, 3b, 3c in FIG. 2) However, the loose stool and urine can be caught reliably.

In addition, the length L3 of the slit 3 is preferably a length that allows soft stools to easily pass through and does not easily return to the skin side. In the case of FIG. 2, which is a general adult incontinence pad, Although the length is about 4 cm, the length L3 of the slit 3 of the present invention is not limited to this.
In FIG. 2, the distance L4 between the slits 3 adjacent to each other in the longitudinal direction Y is about 0.5 cm, which is about 1/8 of the length L3 of the slit 3.
Further, the interval W between the columns G1 and G2, and the columns G2 and G3, the columns G4 and G5, and the columns G5 and G6 adjacent to each other in FIG. 2 is about 1 cm.

The width of the passage means 25 including the plurality of slits 3 as described above is somewhat widened by being attached, but the width is further widened by the weight of loose stool and the excreted pressure.
FIG. 5 (A) shows a state in which the width of the slit 3 is widened. As shown in this figure, when the wearer excretes the loose stool CA, the elastic member directly below the anus with pressure and weight at that time. 28 is pushed, and the loose stool CA tends to spread on the left and right sides of the elastic member 28. Then, due to the weight of the loose stool CA and the pressure at the time of excretion, the left and right sheet body portions 20a of the slit 3 (particularly the slits 3 in the rows G3 and G4 adjacent to the anus) are pushed, so that the slit 3 in FIG. The width W2 widens as shown in FIG. 5A to become a large width W3, and from here the soft stool CA moves to the absorber 19 side (that is, the space S) relatively soon.
At this time, since the elastic member 28 is not arranged adjacent to the left and right sides of the slits 3 in the rows G3 and G4 adjacent to the anus, the slits 3 in the rows G3 and G4 are likely to spread due to the weight of the loose stool CA. It is possible to prevent the elastic member from interfering as much as possible.

In addition, the slit 3 of this embodiment is arrange | positioned in the area | region corresponding to the anal part AN, the female external urethral opening part HR (refer FIG. 3), and these periphery, and also not only soft stool but predetermined amount and Even when urine having pressure is excreted, the width is widened by the weight and pressure, and the urine can move to the space S. Further, since the slit 3 has a length L3 (see FIG. 2) of about 4 cm, a small, hard stool can be moved into the space S.
As shown in FIG. 1, the slit 3 has an elastic force of the elastic member 28 and has a width W2 that slightly widens in advance when the slit 3 is mounted. Therefore, even if the soft stool tries to spread the surface of the sheet body 20 quickly, the slit 3 You can avoid the situation of passing through as much as possible.
Further, in the present embodiment, since the plurality of rows G1 to G6 including the plurality of slits 3 are provided, a large amount or vigorous loose stool CA is excreted, and the loose stool CA can be captured by the rows G3 and G4 of the slit 3 on the center side. Even if not, the loose stool CA can be moved to the space S by the slits 3 of the outer rows G2, G5, etc., as shown in FIG.

  And after excretion is complete, as shown in FIG. 5 (B), the soft stool CA accommodated in the space S is absorbed by the absorber 19 (of course, there are also soft stools that are not absorbed). At this time, the sheet body 20 has a width W4 in which the slit 3 also tries to return to the original state by the force of the elastic member 28 to return to the state before excretion. In addition, since the excretion may adhere to the sheet body 20 after excretion, the width W4 of the slit 3 after excretion may not be completely restored as in the width W2 of FIG. However, a predetermined restoration is performed. Therefore, the excrement accommodated in the space S can be effectively prevented from touching the skin. Further, as described above, the gather 29 in the vicinity of the elastic member 28 of the sheet body 20 reduces the area in which the sheet body 20 itself touches the skin, and even if the sheet body 20 is wet, it can avoid feeling uncomfortable. .

Next, the perforation 64 will be described mainly with reference to FIGS. 1 to 3, 8, and 9.
As shown in the figure, the absorbent product 10 allows for the insertion of a penis and serves both for men and women.
That is, as shown in FIGS. 1 and 2, the sheet body 20 has a substantially horizontal direction at a position corresponding to the base of the penis when the male wears the absorbent product 10 with the reduced width portion 12 applied to the crotch portion. A perforation 64 formed by intermittently arranging a plurality of cuts 61 along the (substantially width direction) X is formed.
Therefore, when a man wears, the part of the perforation 64 of the sheet body 20 is torn, and the penis MS is inserted between the sheet body 20 and the absorber 19 as shown in FIG. The urine from can be absorbed by the absorber 19.
Further, when the female uses, as shown in FIG. 3, the perforation 64 does not open unless the perforation 64 is torn. Therefore, loose stool or the like entering from the passage means 25 is removed from the perforation 64 to the skin side. Can be prevented as much as possible. In the case of the present embodiment, as shown in FIG. 1, there is no elastic member 28 in the region where the perforation 64 is disposed (the elastic member 28 is relatively disposed on the anus side), and the absorbent product The elastic member 28 exerts an urging force in the longitudinal direction Y after the both end portions 10 a and 10 b of 10 are fixed to the pants 2. Even in such a state, the notch 61 is formed to have a short length so that the width of the notch 61 is expanded and does not open under the influence of the elastic member 28 (at least shorter than the passage means 25). .

Specifically, the sheet body 20 shown in FIG. 1 has fiber orientation in the front-rear direction (longitudinal direction) Y, guides urine in a direction connecting the wearer's lower abdomen and buttocks along the fibers, (Short direction) It effectively prevents urine from leaking from the end of X. Thus, when there is fiber orientation in the front-rear direction Y, there is almost no stretch in the front-rear direction Y, while there is a predetermined stretch in the left-right direction X. Then, the row of perforations 64 formed substantially along the left-right direction X is difficult to tear due to the stretchability in the left-right direction X, and if this is forcibly cut, it is inadvertently broken in the front-rear direction Y There is a risk of doing.
Therefore, the perforation 64 of the present embodiment includes first and second perforation rows 62 and 63 which are parallel to each other in the front-rear direction Y, and the first perforation row 62 and the first perforation row 62 The positions of the incisions 61 are alternately (alternately) formed in the left-right direction X with respect to the second perforation line 63. Therefore, as shown in FIG. 8, when the region of the perforation 64 is pulled in the front-rear direction Y, it is between the end 62a of the first perforation 62 and the end 63a of the second perforation 63 adjacent thereto. Since NF is hardly stretchable in the front-rear direction Y, it is relatively easy to tear, and the NF tears at the NF between the first perforation 62 and the second perforation 63, so that the entire left-right direction X The insertion hole 66 for inserting the penis MS can be formed as shown in FIG.

Note that the passage means 25 of the present embodiment is the slit 3 as described above, so that the width of the slit 3 is narrower than that of the long hole, so even if the urine jumps when a man urinates, The opportunity to touch the skin can be avoided as much as possible.
Further, in the present embodiment, the elastic member 28 along the front-rear direction Y in the center in the left-right direction makes it easy to insert a penis between the sheet body 20 and the absorber 19 as shown in FIG. Although the space S is formed and the penis is easily inserted, as shown in FIG. 7 which is a modified example of the present embodiment, a non-woven sheet (for example, a known top) having a smoother surface than the tissue 17 A surface material (also called a sheet) 30 may be arranged on the space S side of the absorber 19.
In addition, as shown in FIG. 8, as a preferred embodiment in the present embodiment, the end 62 a of the first perforation 62 and the end 63 a of the second perforation 63 adjacent thereto are positioned in the left-right direction X. Although it is substantially the same, the present invention is not limited to this, and even if the notches 61 of the first perforation 62 and the second perforation 63 in FIG. (For example, when an imaginary line is drawn from the end 63a of the second perforation 63 in the Y direction of FIG. 8, the imaginary line may hit any position of the cut 61 of the first perforation 62. ).

The first embodiment is configured as described above, and effectively accommodates loose stool in the space S and effectively prevents the contained loose stool from touching the skin, regardless of whether it is male or female. In addition, it is possible to realize the absorbent product 10 in which urine can be appropriately absorbed by the absorber 19.
The first and second perforation lines 62 and 63 are one line in the drawing, but the present invention is not limited to this, and may be two or more lines, for example.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. 10 to 12 show an absorbent product 32 according to the second embodiment, FIG. 10 is a schematic perspective view, FIG. 11 shows a case where the absorbent product 32 is mounted and cut at the CC position in FIG. FIG. 12 is a schematic cross-sectional view, and FIG. 12 is a view for explaining the use state of the absorbent product 32 at the cross-sectional position of FIG. In these figures, the gathers 29 shown in FIGS. 1 and 4 are omitted.
The absorbent product 32 in these figures is mainly different from the absorbent product 10 in FIGS. 1 to 9 in the arrangement of the elastic member 33 and the passage means 35.

That is, the elastic member 33 has the same configuration as the elastic member 28 described above, but the arrangement and number thereof are different. As shown in FIG. 10 and FIG. It is arranged along the longitudinal direction Y on both the left and right sides of the anal part so as to be adjacent to the part.
And the passage means 35 has the row | line | column G9 which consists of the some slit 3 pinched | interposed into the elastic members 33 and 33 adjacent to this anal part. The structure of the slit 3 itself is the same as that already described, but the rows of the plurality of slits 3 along the longitudinal direction Y are five rows G7 to G11 as shown in FIG. One less than the columns G1 to G6 and symmetrical with respect to the column G9 at the center in the width direction X.

The absorbent product 32 according to the second embodiment of the present invention is configured as described above. Thus, even if the elastic members 33 and 33 are not necessarily disposed directly below the anus, they are disposed adjacent to the anus. If so, the effects described in FIGS. 1 to 9 can be exhibited.
Moreover, as shown to FIG. 12 (A) which shows the use condition of the absorptive product 32, the excreted loose stool CA is the slit pinched | interposed into the elastic members 33 and 33 arrange | positioned on both right and left sides adjacent to an anus. 3, it is possible to immediately move to the absorber 19 side and suppress the loose stool CA from spreading in the lateral direction where the width of the surface of the sheet body 20 is narrow. In addition, since the elastic member 35 is not disposed directly below the anus, it is possible to eliminate the poor wearing feeling that the sheet body 20 is in close contact with the anus.
Moreover, since there are two rows of elastic members 35, the restoring force of the sheet body 20 after excretion is stronger than in the first embodiment.
In the absorptive product 32 of the second embodiment, the number of rows of the slits 3 is as small as five rows G7 to G11. However, even if a large amount or vigorous loose stool CA is excreted, FIG. As shown in B), the elastic members 33 on the left and right sides serve as a barrier to some extent, and can be prevented from flowing vigorously in the width direction (short direction) X.

[Third Embodiment]
Next, a third embodiment of the present invention will be described. 13 and 14 show an absorbent product 37 according to the third embodiment, FIG. 13 is a schematic perspective view, and FIG. 14 shows a case where the absorbent product 37 is mounted and cut at the DD position in FIG. It is a schematic sectional drawing. In these figures, the gathers 29 shown in FIGS. 1 and 4 are omitted.
The absorbent product 37 in these figures is different from the absorbent product 10 in FIGS. 1 to 9 in that an elastic member 40 is additionally provided.

That is, the elastic member 28 at the center in the width direction X described above is the first elastic member 28, and the sheet body 20 is arranged around the aggregate of the plurality of slits 3 (the elastic member 28 at the center, Second elastic members 40, 40 are provided on the left and right outer sides of the plurality of slits 3) affected by the elastic force.
The second elastic member 40 on the left side in the width direction X and the second elastic member 40 on the right side have the same configuration, are arranged along the longitudinal direction Y, and the row G1 of the outermost slits 3 in the width direction X. , G6.
Note that the elastic force of the first elastic member 28 and the second elastic member 40 may be different. In this case, the second elastic member 40 is made weaker than the elastic force of the first elastic member 28. May be.
The absorbent product 37 according to the third embodiment of the present invention is configured as described above. For this reason, as shown in FIG. 14, the adhesiveness of the sheet body 20 to the skin can be improved, and a large amount of momentum can be obtained. Even if it is a good soft stool, the portion 20b, 20b of the sheet body in which the second elastic members 40, 40 are arranged can be in close contact with the skin to prevent so-called side leakage, and the excretion is finished. The restoring force of the subsequent sheet body 20 can also be improved as compared with the first embodiment.

[Modification of Third Embodiment]
Next, a modification of the third embodiment of the present invention will be described. FIG. 15 is a partial plan view in which the absorbent product 39 according to the modification is stretched and spread, and the periphery of the passage means 25 of the sheet body 20 is viewed from the plane. In addition, the right side of FIG. 15 is the end part 10b on the buttocks side, and the left side is the end part 10a on the lower abdomen side. In this figure, the gathers 29 shown in FIGS. 1 and 4 are omitted.
The absorbent product 39 in FIG. 15 is different from the absorbent product 37 in FIGS. 13 and 14 in that the passage means 25 has slits 5 having different directions.
That is, the passage means 25 formed on the sheet body 20 is the slit 3 along the longitudinal direction (the wearer's front-rear direction) Y in the area AR1 from the crotch part to the anus part, as in FIG. 13, and this area AR1. In the region AR2 on the waistline side, the slit 5 is formed substantially along the waistline direction. The absorbent product 39 of this modification is a urine-absorbing pad and is not worn around the waistline, but is worn only from the abdomen through the crotch to the waist, so the slit 5 is in the left-right direction (width direction of the wearer). X).
The slit 5 in the width direction X is disposed on the waist side of the elastic members 28 and 40, and is disposed so that excrement flowing between the rows G1 to G6 of the slit 3 hits.

  This modification is configured as described above, and accordingly, when loose stool flows into the waistline area AR2 (for example, loose stool flows to the waist side while sleeping with the buttocks raised to prevent bed slippage). Even in this case, the slit 5 can catch the loose stool and move it to the absorber side, thereby preventing the loose stool from leaking.

[Fourth Embodiment]
Next, a fourth embodiment of the present invention will be described. FIG. 16 is an absorptive product 42 according to the fourth embodiment, and is a schematic longitudinal sectional view when the absorptive product 42 is mounted and cut in the left-right direction in the vicinity of the wearer's outer urethral opening. In this figure, the gathers 29 shown in FIGS. 1 and 4 are omitted.
The absorbent product 42 in this figure is different from the absorbent product 37 in FIGS. 13 and 14 in that the sheet body 20 and the absorbent body 19 are partially connected.
That is, between the sheet body 20 and the absorbent body 19 of the absorbent product 42, there is a connecting portion 43 that is a member through which urine can permeate and partially connects the sheet body 20 and the absorbent body 19. Is provided. Therefore, even if the space S is formed, urine adhering to the sheet body 20 after excretion can be guided to the absorber 19 side through the connecting portion 43. In addition, since this connection part 43 connects the sheet | seat body 20 and the absorber 19 partially, the accommodation amount with respect to the soft stool of the space S is not inhibited significantly.

In the connection portion 43 of the present embodiment, the outer sheet body 27 made of nonwoven fabric, which is a layer on the absorbent body 19 side of the multi-layer sheet body 20, is partially stretched to absorb the absorbent body 19 (specifically, the tissue 17). The extended portion of the outer sheet body 27 becomes the connecting portion 43. The connecting portion 43 and the absorber 19 are preferably connected by thermocompression bonding so as not to impede urine penetration.
Further, the outer sheet body 27 has a higher fiber density than the skin side sheet body 26, and as a result, the fiber density of the connecting portion 43 is also formed higher than the fiber density of the skin side sheet body 26. Thereby, the urine adhering to the sheet body 20 can be actively guided to the absorber 19 side by a capillary phenomenon by the connecting portion 43 having a relatively high fiber density.

Moreover, it is preferable that the connection part 43 is connected to the part close | similar to the elastic members 28 and 40 among the sheet bodies 20, Thereby, the urine adhering to the circumference | surroundings of the elastic members 28 and 40 is absorbed more actively. Since it can guide to 19 side, even if the area | region of the elastic members 28 and 40 tends to closely_contact | adhere to skin after excretion, a wearing feeling can be improved.
In the case of FIG. 16, as a more preferable aspect, the connecting portion 43 is connected only to a portion close to the elastic members 40, 40 on the left and right outer sides in the width direction X than the aggregate of the plurality of slits 3. Thereby, the connection part 43 does not become an obstacle when inserting the penis into the space S.
In the case of the present embodiment, only the portion 27 a of the outer sheet body 27 sandwiching the elastic member 40 together with the skin-side sheet body 26 is extended to the absorber 19 side. About the part 27a of this outer side sheet | seat body 27, it cooperates with the skin side sheet | seat body 26, clamps the elastic member 40 so that the elastic member 40 can be reliably affixed on the sheet | seat body 20, and is in a hook shape or a pleat shape. It is stretched and connected to the absorbent body 19, and the stretched hook-shaped or pleated-shaped portion is a connecting portion 43.
Such a hook-shaped or pleated-shaped connecting portion 43 is continuously formed along the wearer's front-rear direction (longitudinal direction Y in FIG. 13), and partitions the space S in the wearer's left-right direction X. Yes. Accordingly, in the case of FIG. 16, the space S is partitioned into the spaces S1, S2, and S3 to prevent the excrement from flowing in the short left-right direction X and leaking from the side.

The absorbent product 42 of the fourth embodiment is configured as described above. For example, in the case of a woman, loose stool and a large amount of urine are moved to the absorber 19 side by the passing means 25, and a sheet body after a small amount of urine and excretion. The urine remaining in 20 can be moved to the absorber 19 side via the connecting portion 43. Thus, it is possible to avoid touching the body as much as possible regardless of whether it is urine or loose stool, and to avoid feeling uncomfortable and skin trouble after excretion.
The present invention is not limited to the embodiment shown in FIG.
For example, the connecting portion 43 is not limited to the one that directly connects the sheet body 20 and the absorbent body (including the tissue 17) 19, and is called, for example, a top sheet that covers the skin-side surface of the absorbent body 19. You may connect a surface material and the sheet | seat body 20 via the connection part 43. FIG.
Moreover, in this embodiment, although the connection part 43 is formed by extending | stretching the outer side sheet body 27 of the sheet body 20 to the absorber 19, the sheet body 20 and the connection part 43 are formed from completely different members. May be. At this time, it is preferable that the fiber density of the connecting portion 43 is higher than the fiber density of the outer sheet body 27, so that urine is positively guided to the absorbent body 20 side and the urine adhering to the connecting portion 43 is not removed. The situation transmitted to the body 20 side can be prevented.
Moreover, in this embodiment, although the connection part 43 is connected only to the part close | similar to the elastic member 40, if it does not interfere with insertion of a penis, it will be connected to the part close | similar to the elastic member 28 of a center part. Also good. At this time, it is preferable to arrange the connecting portion 43 only around the female external urethral orifice HR (see FIG. 9), thereby preventing the possibility of impeding the insertion of the penis and the space S around the anal portion. It is also possible to ensure the capacity for loose stool.
Furthermore, the connection part which connects the sheet | seat body 20 and the absorber 19 between the female external urethral opening HR shown in FIG. 9 and the front-end | tip of the penis MS inserted from the insertion hole 66 is shown in FIG. Along the direction X, it may be arranged in almost all regions except the passing means 25 to partition the wearer's front-rear direction. This prevents the urine from the penis MS shown in FIG. 9 from flowing into the space S on the anus AN side as much as possible, and the urine passes through the passage means 25 around the anus AN and around the anus AN. The risk of adhesion can be prevented more effectively.

[Fifth Embodiment]
Next, a fifth embodiment of the present invention will be described. FIG. 17 is an absorbent product 50 according to the fifth embodiment, and is a schematic cross-sectional view when the absorbent product 50 is mounted and cut in the left-right direction. In this figure, the gathers 29 shown in FIGS. 1 and 4 are omitted.
The absorbent product 50 in this figure is different from the absorbent product 37 in FIGS. 13 and 14 in that the sheet body 20 is provided with a bellows-like portion.

That is, as shown in FIG. 17, the sheet body 20 has a plurality of bent portions 49 that are bent in the left-right direction (width direction X) of the wearer by alternately repeating mountain folding and valley folding, and has a bellows shape. It has area | region AR3 which became. Accordingly, the wearer's left and right dimensions can be increased compared to the flat sheet body 20, and even if the crotch portion is narrow in the left and right direction, the situation where the excrement immediately reaches both ends in the width direction is suppressed. it can. In particular, since the angle θ1 is attached to the wearer's left and right direction, even if the wearer lies down sideways, the excrement is in the wearer's left and right direction (up and down direction of lying down sideways). It is possible to move the excrement from the passage means 25 to the space S easily by reducing the transmission speed.
In addition, what is necessary is just to hold | maintain the shape of such a bellows shape substantially by elastic members (not shown), such as a synthetic rubber provided in the both ends of the longitudinal direction Y along the width direction X.
In addition, the bellows-shaped region AR3 is bilaterally symmetric with respect to the valley-folded bent portion 49a in the central portion in the width direction X (the portion corresponding to the anus when attached), and the same number ( It has three bent portions 49 in the case of the figure.

  In the case of the figure, the elastic member 52 having a circular cross section is disposed along the longitudinal direction Y on the left and right sides of the anus so as to be close to the anus at the center in the left and right direction. Specifically, the elastic member 52 is sandwiched and connected between the skin side sheet body 26 and the outer sheet body 27, but is disposed on the mountain fold side (skin side). In addition, although the elastic member 52 of this embodiment is arrange | positioned in the center part of the width direction X as a preferable aspect which is easy to put a penis in the space S, this invention is not limited to such an aspect, width | variety You may arrange | position between the center part of the direction X, and the elastic member 40, or may provide only the right and left elastic members 40 and 40, without providing the elastic member 52.

  The passing means 25 of the present embodiment is the same slit 3 as in FIG. 1 in its own form, but as shown in FIG. 17, the bent portion 49 along the longitudinal direction Y extends along the longitudinal direction Y. It is formed intermittently. Thus, when loose stool or the like is excreted, the bellows-like bending angle θ1 is increased due to the weight of the loose stool or the like and the excreted pressure. Therefore, the width of the slit 3 becomes easier to spread, and excrement can be easily moved in the space S. After the excretion is finished, the elastic force of the elastic members 40 and 52 allows the width of the slit 3 to return before excretion, thereby preventing the excrement accommodated in the space S from contacting the skin more effectively. .

By the way, this invention is not limited to the said embodiment, The separate structure of the above-mentioned embodiment may be abbreviate | omitted as needed, or may be combined with the other structure which is not demonstrated.
For example, in the embodiment described above, the urine collecting pad is exemplified, but a pants-type diaper or the like may be used.
Further, the number, type, and dimensions of the passing means 25 of the present invention are not limited to the above-described embodiment.
Moreover, in the said embodiment, although the slit was mention | raise | lifted as an example of the passage means 25, a narrow long hole may be sufficient, or you may use combining a slit and a long hole.
Moreover, you may arrange | position the surface material called a well-known top sheet in the space S side of the absorber 19 of embodiment of FIGS.
