Description

  The present invention relates to a male absorbent article. More specifically, the present invention relates to an absorbent article for men that is easy to be worn by any wearer regardless of the size of the male penis, and that does not fall off even if urine is transmitted to the ventral side.

  In addition to basic absorptive articles such as tape type and underpants type, excreta absorbent articles (diapers) for adults are what are called smaller flat types and pad types that are supposed to be used in combination with these. These combinations are commercially available, and are widely used particularly in nursing care sites such as care facilities. That is, in the case of a wearer or the like in which crimping has occurred, it may be difficult to properly fit the wearer's body surface with only the above basic absorbent article. The auxiliary absorbent article is deformed into an appropriate shape such as a loose shape, and is sandwiched in the gap between the body surface and the basic product (or the part where gaps are likely to be generated), or rolled into a cone when the wearer is male. A measure to wrap around the penis (hereinafter also referred to as male winding) is taken.

  There exist invention of patent document 1 and patent document 2 as a bag-shaped pad type thing.

JP 2001-204755 A JP 2011-30962 A

However, the bag-shaped pad type of Patent Document 2 is difficult to wear when the male genitalia is short, and may come off after wearing.
In this respect, Patent Document 1 is superior in terms of wearability, but depending on the orientation and state of the male genital, a space is created between the male genital and the pad, urine is not absorbed by the pad, and the skin is It may be leaked from the ventral side.
One of the reasons is that, considering the number of purchasers, a plurality of pads are not provided according to the size of male genitalia, so that it is apt to be limited to a single size.
In this respect, when it is so-called male winding, because it is wound around the penis in the field according to the size of the subject's male genitals, it is mounted regardless of whether the male genitals are short, etc. Due to the size of the male genitals (especially the penis diameter is small), there is a space between the male genitalia and the pad, and the leakage tends to be relatively small.

  Although the so-called male winding has advantages, it is still not possible to solve the problem, depending on the orientation and condition of the male genitalia during the wearing process, for example, if the tip of the male genital warps back to the ventral side, it protrudes from the pad Urine may not be absorbed by the pad and may travel through the skin and leak from the ventral side.

  In addition to the pad that covers the penis, in addition to the pad that covers the penis, another user puts an absorbent pad on the stomach to prevent leakage. There is a problem that it is costly and costly.

  The present invention has been made in order to solve the above-described problems, and it is an object of the present invention to provide a male pad that is excellent in wearability and can effectively prevent leakage regardless of the size of a male genitalia.

As an invention according to claim 1 for solving the problems of the present invention,
It has a surface sheet provided on the use surface side, a back sheet provided on the back surface side, and an absorption element that absorbs bodily fluid that is interposed between them and is transmitted from the use surface side,
The abutting portion, the extending portion extending from the abutting portion, and the covering portion continuing from the extending portion are L-shaped in a developed plan view, and the two inner sides of the L-shape are in the product state. Are joined together,
At the time of wearing, the abutment portion is applied to the wearer's inguinal lower abdominal region that is substantially partitioned by the wearer's left and right inguinal portions and the region that spans these including the wearer's penis,
The extending portion extends from the contact portion below the wearer,
A penis insertion part is formed on the lower side of the contact part,
The covering portion has left and right separated covering pieces as a pair capable of meeting, separated into right and left,
At the time of wearing, at least the tip side portion of the penis is inserted from the abdomen side of the wearer to the opposite side through the insertion portion, and in this insertion state, the lower side of the penis faces the extension portion. And
The upper side of the wearer's penis is covered by a pair of separated covering pieces,
The tip side portion of the penis is configured to be wrapped with the extending portion and the covering portion,
An absorbent article for men is provided.

(Function and effect)
A penis insertion part is formed on the lower side of the contact part, and at the time of wearing, at least the tip side part of the penis is inserted from the abdomen of the wearer of the contact part to the opposite side through the insertion part. In the inserted state, the lower side of the wearer's penis faces the extension.
On the other hand, for the upper side of the wearer's penis, mainly by the meeting of the left and right separation covering pieces after insertion of the penis, or by the insertion of the penis after meeting of the left and right separation covering pieces according to the size of the penis The upper side of the penis is covered, and at least the tip side portion of the penis of the wearer is wrapped with the extension part and the covering part.
Therefore, since the separation covering pieces are arranged according to the size of the subject's penis, it is difficult for the male absorbent article to come off. In addition, the penis insertion and the separation covering piece meeting are not complicated, and can be performed relatively easily.
The meeting of the separation covering pieces according to the size of the subject's penis can prevent separation from the extension part and the covering part and ensure a contact state, and thus has a high leakage prevention effect.
Furthermore, even if it tries to leak to the abdomen, the penis insertion part is formed on the lower side of the contact part.On the contrary, in the penis insertion state, the contact part exists on the umbilicus side from the penis. Therefore, the contact portion can absorb leaked urine, and leakage to the outside can be prevented. For example, the effect of preventing leakage to the outside is brought about when urination occurs when the penis is inserted through the insertion part and the tip side of the penis warps to the umbilicus.

  As a second aspect of the invention, at least a portion corresponding to the penis portion through which the contact portion, the extending portion, and the covering portion are inserted is liquid-permeable on the use surface side and liquid-impermeable on the back surface side. An absorbent article for men according to claim 1 is provided.

(Function and effect)
At least the part corresponding to the penis part through which the contact part, the extension part and the covering part are inserted is liquid permeable on the use surface side and liquid impervious on the back side, and transmitted from the use surface side between them. Since the body fluid absorption element is interposed, when urination occurs, urine can be transmitted from the use surface side and absorbed by the absorption element.

  According to a third aspect of the present invention, there is provided the absorbent article for men according to the first aspect, wherein the insertion portion has a substantially liquid drop shape in which the lower portion is narrowed and the upper portion is swollen.

(Function and effect)
When the penetrating part is in the shape of a droplet with the upper part swollen and the upper part swollen, after inserting the penis, the edge of the lower part of the penetrating part is in contact with the outer peripheral surface of the penis. Leakage from between the outer peripheral surface and the edge of the insertion portion can be suppressed. In addition, when the shape of the insertion portion is, for example, a circle, it does not open to a diameter larger than that, but according to the present invention, when the insertion portion is a substantially droplet-shaped insertion portion that swells upward when not in use, The edge of the narrowed portion below the insertion portion changes in shape three-dimensionally, and the entire insertion portion opens larger than the maximum diameter portion of the droplet shape when not in use, allowing penis insertion. Therefore, by reducing the diameter of the maximum diameter portion of the droplet shape and positively contacting the edge of the insertion portion with the outer peripheral surface of the penis, the effect of suppressing leakage can be enhanced.

  According to a fourth aspect of the present invention, there is formed a notch portion that is formed on the lower side of the insertion portion to the left or right, or that extends to the left or right across the insertion portion and that is formed in advance or is broken by a user operation. A male absorbent article according to claim 1 or 3 is provided.

(Function and effect)
If the notch is formed, the action of the vertical deformation force of the penis after insertion through the penis becomes the force that lifts and deforms the extended portion with respect to the abutment, and the notch depends on the deformation force. Because the part opens, there is no deformation resistance, it deforms as it is, it becomes easy to follow the deformation of the extension part, the maintenance of the contact state between the outer peripheral surface of the penis and the edge of the insertion part is stable, leakage The suppression effect is high.

  5. The male absorption according to claim 4, wherein the notch is located at a boundary between the contact portion and the extending portion, and the absorbing element is not provided at the boundary. A sex article is provided.

(Function and effect)
The notch portion in which the absorption element is not provided is easily opened by the action of the deforming force, and the function and effect of claim 4 are remarkably exhibited.

  As a sixth aspect of the present invention, there is provided the absorbent article for men according to the first aspect, wherein a joining portion for maintaining a meeting state of the pair of separation covering pieces is formed.

It is a top view of the example which formed the notch part on either side of the other insertion part. It is a top view for description of the relationship between the penis and the insertion part in the aspect of FIG. It is the front view which showed the wearer's inguinal lower abdominal area Z.

Hereinafter, the form for implementing the absorbent article of this invention is demonstrated concretely, referring drawings.
In the following description, the vertical direction in “upper” and “lower” refers to the vertical (extension) direction in a state where the absorbent article of the present invention is worn as shown in FIG. "Left and right" refers to the left and right direction (left and right width direction with respect to the center of the body) when the absorbent article of the present invention is worn as shown in FIG.
Further, “the penis lower side” refers to the side of the penis close to the testis, and “the penis upper side” refers to the side opposite to the penis lower side.

  When the absorbent article for men of the present invention is worn, as shown in FIG. 5, the left and right inguinal portions m and m of the wearer M and the region straddling these including the penis P of the wearer M are substantially included. The contact portion 10 applied to the inguinal lower abdominal region Z (FIG. 11) of the partitioned wearer, the extending portions 20A and 20B extending downward from the contact portion 10 to the wearer, and continuous from the extending portions 20A and 20B And a covering portion 30 that covers at least the tip side portion of the penis P of the wearer from above; the penetrating portion 1 of the penis P is formed on the lower side of the contact portion 10, and the covering portion 30 is The left and right separation covering pieces 30A and 30B as a pair that can be separated are separated, and at the time of wearing, at least the tip side portion of the penis P is opposed through the insertion portion 1 from the abdomen side of the wearer of the contact portion 10 The pendant P lower side of the wearer M is the extended portion in this inserted state. The upper side of the penis P is covered by a meeting of the left and right separation covering pieces 30A, 30B with respect to the upper side of the penis P of the wearer M, and at least the tip side of the penis P of the wearer extends 20A. , 20B and the covering portion 30.

As shown in FIGS. 1 to 3, the absorbent article for men of the present invention is provided with an absorbent element 52 made of cotton pulp or the like on the liquid-impermeable back sheet 51 as shown in FIGS. A liquid-permeable surface sheet 53 is provided on the (use surface side), and is formed into, for example, an L shape shown in FIG.
In this case, an absorbing element 52 is provided at a predetermined position of at least the abutting portion 10, the extending portions 20A and 20B, and the separation covering piece 30A (preferably also the separation covering piece 30B).

  On the other hand, at the final stage of production, the L-shaped open side edges are joined to each other by, for example, the part indicated by the symbol S in FIGS. 1 and 2 by heat welding or hot melt adhesive. Moreover, the penetrating part 1 having an appropriate shape for the penis P is formed. The shape of the insertion portion 1 in the illustrated example has a substantially droplet shape in which the lower part is narrowed and the upper part is swollen. The shape of the insertion part 1 may be a simple circle, but if it is a droplet shape, it brings the advantages described later.

  Further, in the embodiment, the L-shaped boundary portion extends to the left and right of the insertion portion 1 below (extends to the left and right in the wearing state), and is preliminarily formed or broken by a user's operation by a perforation or the like. Notches 40A and 40B are formed.

  2, 4, and 5, in order to maintain the meeting state of the left and right separation covering pieces 30 </ b> A and 30 </ b> B and maintain the covering state on the upper side of the penis P, the corner portion of the separation covering piece 30 </ b> A is used. The joint portion 60 is provided in the above. The joint portion 60 is obtained by covering the adhesive application portion 60a with a release tape 60b. In use, the separation tape 60b is peeled and removed to expose the adhesive application portion 60a, and the separation coating piece 30A is exposed on the separation coating piece 30A. 30B is brought into a meeting state (superimposed state of the front body).

  On the other hand, since the absorbing element 52 described above has a property of imparting rigidity and inhibiting folding, the valley shown in FIGS. 1 to 3 is finally formed for the purpose of folding in FIGS. 4 and 5. Since it is desirable to form a valley fold along the fold line (dashed line), it is desirable not to provide the absorbent element 52 at the location of the valley fold line.

  In using the male absorbent article of the present invention, the product is expanded from the state of FIG. 2 and applied to the wearer's local area as shown in FIG. At that time, the penetrating part 1 is inserted through the penis P from the back side toward the use side. This insertion state is shown in FIGS.

Moreover, the peeling tape 60b is peeled and removed to expose the adhesive application part 60a, and then valley-folded at the valley fold lines La and Lb to which FIG. 1 is referenced, as shown in FIGS. The separation covering piece 30B is brought into a meeting state (overlapping state of the front body) on the separation covering piece 30A.
As a result, at least the tip side portion of the penis P is inserted from the back surface side of the abutment portion 10 to the use surface side through the insertion portion 1, and the lower side of the wearer M's penis P is extended to the extension portions 20A and 20B. The upper side of the penis P is covered by a meeting of the left and right separation covering pieces 30A and 30B with respect to the upper side of the penis P of the wearer M. This covering state is maintained by the joint portion 60.

  In this case, when the notches 40A and 40B are formed, after the penis P is inserted, the action of the deforming force in the vertical direction of the penis (the deforming force due to the change in the sleeping posture) The extending portions 20A and 20B are lifted and deformed, and the cutout portions 40A and 40B open as shown in FIG. 6 according to the deforming force. It becomes easy to follow the deformation of the extending part, the maintenance of the contact state between the outer peripheral surface of the penis P and the edge of the insertion part is stabilized, and the effect of suppressing leakage is high.

As the shape of the insertion part 1, when the pendulum P is inserted when the lower part is narrowed and the upper part is swollen, as shown in FIG. Leakage from between the outer peripheral surface of the penis and the edge of the insertion portion can be suppressed by contacting the lower peripheral surface of the penis.
Further, when the insertion portion has a circular shape, for example, the insertion portion 1 does not open to a diameter larger than that. However, according to the embodiment, the insertion portion 1 has a substantially droplet shape that swells upward when not in use. In particular, the edge of the narrowed portion below the insertion portion 1 changes three-dimensionally, and as shown in FIG. 8, the entire insertion portion has a larger diameter than the diameter portion D0 of the droplet shape when not in use. It becomes part D1, and the insertion of the penis is permitted. Therefore, by reducing the diameter of the maximum diameter portion of the droplet shape and positively contacting the edge of the insertion portion with the outer peripheral surface of the penis, the effect of suppressing leakage can be enhanced.

As described above, in the present invention, the insertion part 1 of the penis P is formed on the lower side of the contact part 10, and at the time of wearing, at least the tip side part of the penis P is abdomen of the wearer of the contact part 10. Since it is inserted in the opposite side through the insertion part 1 from the side, the lower side of the penis P of the wearer M faces the extension parts 20A and 20B in the insertion state.
On the other hand, for the upper side of the penis P of the wearer M, the left and right separation covering pieces 30A, 30A, 30B depending on the size of the penis P, mainly by the meeting of the left and right separation covering pieces 30A, 30B after the penis P is inserted. By inserting the penis after meeting 30B, the upper side of the penis P is covered, and at least the tip side part of the penis P of the wearer M is covered with the extending portions 20A and 20B and the covering portion 30.
Therefore, since the separation covering pieces 30A and 30B are arranged in accordance with the size of the penis P of the subject, it is difficult for the male absorbent article to come off. Further, the penis P can be inserted and the separation covering pieces 30A and 30B can be arranged in a relatively simple manner without being complicated.
Since the meeting of the separation covering pieces 30A and 30B according to the size of the penis P of the subject M can prevent separation from the extending portions 20A and 20B and the covering portion 30, a contact state can be secured, thus preventing leakage. High effect.
Furthermore, even if it tries to leak to the abdomen, the penetrating part 1 is formed on the lower side of the abutting part. On the contrary, when the penis P is inserted, the abutting part is closer to the umbilicus than the penis P is. Because of this, the contact portion can absorb the leaked urine, and leakage to the outside can be prevented. For example, after inserting the penis P through the insertion part 1, when urination occurs in a state where the tip side of the penis P is warped to the umbilicus side, an effect of preventing leakage to the outside is brought about.

By the way, as a position of a notch part, as shown in FIG.9 and FIG.10, notch part 41A, 41B extended right and left across the insertion part 1 may be sufficient. Similarly, the notches 41A and 41B may be formed in advance or broken by a user's operation.
The notches 41A and 41B can be deformed together with the insertion portion 1 as shown in FIG.

  As the liquid-permeable surface sheet 53 in the embodiment, 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 skin contact surface sheet, urine and the like are quickly absorbed, and the dry touch property is excellent.

  As the liquid-impermeable back sheet 51, a liquid-impermeable plastic sheet such as polyethylene or polypropylene is used. In recent years, a sheet having moisture permeability is preferably used from the viewpoint of prevention of stuffiness. The liquid-impermeable back sheet 51 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. It is.

  As the absorbent element 52, a known one, for example, a pulp fiber stack, a collection of filaments such as cellulose acetate, or a non-woven fabric is basically mixed and fixed with a superabsorbent polymer as necessary. Can be used. The absorbent element 52 can be packaged by a wrapping sheet having liquid permeability and liquid retention, such as crepe paper, if necessary, for holding the shape and polymer. The shape of the absorbent element 52 may be a rectangular shape or a triangular shape as illustrated, a circular shape, or any combination of these shapes.

  In addition, the wearer's inguinal lower abdominal region which is substantially partitioned by the left and right inguinal portions of the wearer and the region straddling them including the wearer's penis in the present invention should not be strictly intervened. It should be understood that the site is suitable for the insertion of the umbilicus and is the lower abdomen under the umbilicus.
