Description

  The present invention relates to a body fluid absorbent article that absorbs body fluid, and particularly to a body fluid absorbent article suitable for men.

Paper diapers are well known as absorbent articles for body fluids such as urine. In general, a disposable diaper is arranged from the middle of the front body to the middle of the back body through the crotch, so that urine is absorbed and retained by the absorbent body during incontinence, etc. It is configured.
JP-A-2005-237782 JP2005-073921

However, in the case of men, the orientation of the penis always changes depending on the posture, etc., so in conventional paper diapers, for example, if urination is made vigorously when the penis is upward (chest direction), the urine becomes a disposable diaper. There was a case of leaking from the waist opening. In addition, if urination is performed vigorously in a sideways state, there may be a leak from the opening around the legs.
Furthermore, in particular, when light incontinence occurs when the penis is lying on its back with the penis facing upwards, urine does not reach the absorber in conventional disposable paper diapers and remains on the lower abdomen of the incontinent person. There were times when people were extremely uncomfortable.
Then, the main subject of this invention is providing the bodily fluid absorptive article which does not have the leak of urine and discomfort resulting from the direction of such a penis.

The present invention that has solved the above-described problems and the effects thereof are as follows.
<Invention of Claim 1>
A paper diaper main body part in which a front body and a back body are connected via a crotch part, and a body fluid absorbing element is arranged from the front body to at least the crotch part,
A bag body having a bag portion having a function of absorbing and holding body fluid therein and an end piece formed by extending a part of the opening edge of the bag portion;
The bag body is bonded to the front body of the diaper main body at the extended end edge portion of the end piece, and a free portion excluding the bonded portion rotates in the front-rear direction of the diaper main body using the bonded portion as a base. A bodily fluid-absorbing article characterized in that it is made freely and has a penis insertion hole or notch formed in its end piece.

(Function and effect)
In the present invention, the bag is bonded to the front body of the paper diaper main body at the extended edge of the end piece formed by extending a part of the opening edge of the bag, and the remaining free part is the bonded part. The diaper main body is rotated in the front-rear direction with the base as a base. Therefore, when the wearer wears the paper diaper main body, it is possible to move the free portion of the bag up and down. Therefore, for example, in a state in which the opening portion of the bag body is positioned on the paper diaper main body side in a normal state (a state where the paper diaper main body portion is mounted and the free portion of the bag body is lowered), the bag portion is naturally The opening is on the ventral side in the state of screaming. And in this invention, since the hole part or notch part for penis insertion is formed in the end piece of a bag body, if it says in the said form, the bag part of a normal state (state which is not raised) The penis can be inserted downward through the hole, and the penis can be directly inserted directly into the bag without passing through the hole.
In the normal state (the state in which there is no talk), in the form in which the opening is located on the ventral side, the penis is inserted downward into the bag part without inserting the penis into the hole part, When it is raised, the penis is inserted into the bag part upward through the hole or the like.
Thus, in the present invention, the penis can be reliably inserted into the bag portion regardless of whether the penis is upward or downward. And since a bag part has a bodily fluid absorption capability, even if incontinence arises in the state which inserted the penis, for example, if it is a small amount, urine can be retained in the bag. Moreover, even if urine in an amount that cannot be absorbed into the bag is released, it can be absorbed by the absorbent element that exists from the front body of the diaper main body to the crotch. Furthermore, even if urine is released at this time, it hits the inner bottom of the bag portion and is suppressed. Therefore, the possibility of leakage from the waist opening and the underbody opening of the diaper body is markedly reduced.
In the present invention, the wearer selects whether to insert the penis downward, upward, or through the hole into the bag.

<Invention of Claim 2>
The bodily fluid absorbent article according to claim 1, wherein an elastic elastic member is arranged around the hole or around the notch, and the hole diameter or the size of the notch can be changed.

(Function and effect)
When versatility with respect to penis size increases and the periphery of the hole or notch fits into the penis inserted into the hole, etc., so that the penis is inserted through the hole and inserted into the bag In, the urine made in the bag portion is reliably prevented from moving to the lower abdomen through the insertion hole.

<Invention of Claim 3>
The bodily fluid absorbent article according to claim 1 or 2, wherein a locking member for temporarily fixing the free portion of the bag body to the diaper main body is provided.

(Function and effect)
The bag portion can be temporarily fixed. For example, when there is little movement of the penis in the vertical (front / rear) direction, such as when there is little change in posture such as at bedtime, the leakage prevention effect is improved by suppressing the movement of the free part. For example, when the penis is facing upward, it can be temporarily fixed to the diaper main body with the bag portion raised.

<Invention of Claim 4>
The body fluid absorbent article according to any one of claims 1 to 3, wherein an elastic elastic member is interposed between at least the adhesive portion and the bag portion.

(Function and effect)
Since the elastic expansion / contraction member is provided between the bonding portion and the bag portion, the elastic expansion / contraction member expands / contracts so that the bag portion can move not only in the front-rear direction but also in the left-right direction. Therefore, the bag portion can be made to follow the movement of the penis more flexibly and the bag portion can be made to follow more flexibly.

  As described above, according to the present invention, a bodily fluid absorbent article free from urine leakage and discomfort caused by the orientation of the penis is provided.

(First embodiment)
<Overview>
The pants-type disposable paper diaper 1 as a body fluid absorbent article according to the present embodiment is the same as a conventional general pants-type disposable paper diaper in appearance as shown in FIG. The disposable paper diaper of the present embodiment is on the side in contact with the skin of the front body F of the paper diaper main body 1X, as will be apparent from the plan view in the unfolded state shown in FIG. 2 or the partial sectional view shown in FIG. The bag body 1Y is bonded.

<About the diaper body>
As shown in FIGS. 1 and 5, the disposable diaper main body 1X absorbs cotton pulp or the like between a liquid-permeable top sheet 11 made of nonwoven fabric and the liquid-impermeable back sheet 12 made of polyethylene or the like. An absorbent element 10 having a body 13 interposed therebetween and an exterior sheet 20 integrally provided on the outer surface side of the absorbent element 10, and the front body and the back body of the exterior sheet 20 are joined at both sides in the product state. This is a pants-type disposable diaper having a structure in which a waist opening and a pair of left and right leg openings are formed.

  As described above, the absorbent element 10 has a structure in which the absorbent body 13 such as cotton-like pulp is interposed between the liquid-permeable top sheet 11 made of nonwoven fabric or the like and the sheet 12 made of polyethylene or the like. Is to absorb and hold.

  In the illustrated example, the absorbent body 13 is formed with a substantially square shape in plan view, and the width dimension thereof is a dimension width that does not give the wearer a feeling of gore by hitting the crotch portion. The absorbent body 13 is surrounded by the crepe paper 14 in order to maintain the shape and improve the diffusibility of the body fluid that has passed through the liquid-permeable top sheet 11. As the absorber 13, it is desirable to use an airlaid absorber that can reduce the bulk.

  As the liquid-permeable top sheet 11 covering the surface side (skin contact surface side) of the absorbent body 13, a porous or non-porous nonwoven fabric or a porous plastic sheet is preferably used. The material fibers that make up the nonwoven fabric can be synthetic fibers such as olefins such as polyethylene or polypropylene, polyesters, and polyamides, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in terms of flexibility and drapeability, and the thermal bond method is excellent in terms of being bulky and soft. When a large number of through holes are formed in the liquid permeable top sheet 11, urine and the like are quickly absorbed, and the dry touch property is excellent. The liquid-permeable top sheet 11 extends to the back side of the absorbent body 13 around the side edge of the absorbent body 13.

  As the liquid-impermeable back sheet 12 covering the back surface side (non-skin contact surface side) of the absorbent body 13, a liquid-impervious plastic sheet such as polyethylene or polypropylene is used. Those having wettability are preferably used. This water-impervious / breathable sheet is a microporous sheet obtained by, for example, melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. If the sheet thickness is the same, the rigidity is lower than that of the non-porous sheet, which is superior in terms of flexibility.

  On the other hand, the exterior sheet 20 is a two-layered nonwoven fabric sheet composed of an upper nonwoven fabric 20A and a lower nonwoven fabric 20B, and various elastic members are disposed between the upper nonwoven fabric 20A and the lower nonwoven fabric 20B to impart elasticity. ing. The planar shape forms a pseudo hourglass shape as a whole by the concave leg-around cut lines 29 formed to form leg openings on both sides of the middle.

  In the exterior sheet 20 according to the present invention, as the elastic member, as shown in the developed shape plan view of FIG. 2, waist elastic members 24, 24... Disposed around the waist opening 23, and the front body F And the back body B has a plurality of waist elastic members 25, 25... Arranged in the horizontal direction at intervals in the up-down direction, and each of the front body F and the back body B has the waist Separately from the rotational elastic member groups 25, 25..., Extends from the one side joint edge that joins the front body F and the back body B to the crotch side, bypasses the crotch side, and joins the other side joint edge of the front body and the back body And a plurality of curved elastic member groups 26, 28,... Arranged at intervals without crossing each other. In the exterior sheet 20, a so-called leg-hole elastic member that is substantially continuous along the leg-hole cut line 29 is not provided, but may be provided.

<About the bag>
On the other hand, as shown in FIGS. 2 to 4 in particular, the bag body 1Y includes a bag portion 31 and an end piece 32 in which a part of the opening edge of the bag portion 31 extends. In particular, the bag body 1Y has a three-sided closed shape in which a substantially rectangular sheet material is folded back with its end edges shifted in the longitudinal direction, and both side edges 31S and 31S of the overlapped portion are thermally welded. Note that the method of bonding the side edges 31S and 31S is not limited to heat welding, and hot melt bonding or the like can also be employed.

  The sheet material of the bag body 1Y is obtained by interposing an absorbent body 34 between the liquid-permeable sheet 37 and the liquid-impermeable sheet 33 as shown in the sectional view of FIG. It is comprised so that it may become a bag part inner surface. Here, the absorbent body 34 is the same material as the absorbent body 13 used for the absorbent element 10 of the paper diaper main body, and the liquid permeable sheet 32 is the same material as the liquid permeable top sheet 11 of the paper diaper main body 1X. As the material of the liquid-permeable sheet 33, the same material as the liquid-impermeable back sheet 12 can be used for the paper diaper main body 1X.

  The bag body 1Y has adhesive portions 32ES and 32ES for adhering to the paper diaper main body portion 1X on both sides 32ES and 32ES of the extended edge portion of the end piece 32, and the extended edge between them. The central portion is cut out to form a cutout portion 32C. This notch edge 32EC is not bonded to the paper diaper main body 1X.

  On the other hand, in the bag body 1Y, elastic elastic members 35, 35 are interposed between the bonding portions (both sides of the extended edge portion) 32ES, 32ES and the bag portion 31, and the elastic elastic members 35, 35 The expansion and contraction of the bag portion allows the bag portion to move slightly in the lateral direction or the bag bottom direction even when the adhesive portions 32ES and 32ES are fixed to the paper diaper main body portion. Here, as the elastic elastic member 35, a flat rubber material, an elastomer film, an elastic sheet in which a thread rubber is interposed between nonwoven fabric sheets, or the like can be suitably used.

<Structure and usage of body fluid absorbent article>
As shown in FIGS. 2 and 5, the bodily fluid absorbent article 1 has the bag 31 in contact with the skin of the front body F of the disposable diaper main body 1 </ b> X at the adhesive portions (extended end edge side portions) 32 </ b> ES and 32 </ b> ES. The free portion 30F that is bonded to the side and includes a part of the remaining bag portion 31 and the end piece 32 is free with respect to the paper diaper main body portion 1X.

  The bag body 1Y is bonded to the paper diaper main body portion 1X so that the extending edge 32E of the bag body 1Y is parallel to the waist line 20E of the paper diaper main body portion 1X. It goes straight to the line 20E. Therefore, as shown in FIG. 5, the free portion 30F is rotatable in the front-rear direction 1A (the height direction of the wearer in the worn state) of the disposable diaper main body 1X with the adhesive portion 32ES as a base, and the free portion 30F. Can be moved up and down, and the opening 30H of the bag 31 can be selected to be upward or downward. Here, the bonding between the paper diaper main body 1X and the bag body 1Y can be performed by a known bonding method such as hot melt bonding or heat welding that is often used for bonding nonwoven fabrics.

  On the other hand, locking members 36 for temporarily fixing the bag 31 to the surface of the paper diaper main body 1Y on the front and back surfaces of the bag 31 and the surface of the paper diaper main body 1X. 36 is arranged. In this embodiment, the locking member is composed of a mechanical fastener, but an adhesive sheet or the like can also be used.

  Subsequently, the usage method of the bodily fluid absorbent article 1 of this form is demonstrated. In the present embodiment, as shown particularly in FIG. 5, the opening 30H of the bag body 1Y is located on the side of the disposable diaper main body 1X in the normal state where the free portion 30F is lowered (the state where it is not raised). And if the free part 30F is raised, the opening part 30H comes to be located in a user's ventral side (S).

  Therefore, in the present embodiment, in a normal state that is not raised, the penis is inserted into the notch 32C formed in the end piece 32, and the penis tip is inserted downward into the bag portion and stored. This use in the normal state is a use mode suitable for a case where the state where the penis is facing downward continues for a long time, for example, when the user is walking or standing.

  On the other hand, in the raised state in which the opening 30H with the bag part 31 raised is positioned on the ventral side (S), the penis is inserted directly into the bag part without passing through the notch part and stored. This raised state is a preferred mode of use when, for example, when the penis tip is facing upwards of the body for a long time, such as at bedtime.

(Other embodiments)
Another form of the bag is shown in FIG. In this embodiment, the bag body 1Y is configured such that the entire extended end edge portion 32EA is an adhesive portion 32EA for the paper diaper main body portion 1X. A penis insertion hole 32H, not a penis insertion notch, is formed at a position close to the adhesive portion 32E of the end piece 32, and a rubber thread 32G is arranged around the hole to provide elasticity. Is provided so that the hole periphery 32HE fits the inserted penis. In this embodiment, no elastic elastic member is disposed between the adhesive portion 32EA and the bag portion 31. Other configurations are the same as those in the first embodiment.

(Other)
In addition, although the said form is a form of the paper diaper main-body part 1X of a pants-type paper diaper, a diaper main-body part is a form of what is called a tape-type paper diaper by which the front body F and the back body B are not joined previously by the waist part. It can also be.

  Moreover, it is good also as a form which the opening part 30H is located in the ventral side S in the said normal state (state which has lowered | hung the bag part without raising).

  The present invention can be used for disposable paper diapers, underwear such as briefs, and other pants-type products.
