Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an absorbent article, and more specifically, it is used together with a diaper cover, a garment or underwear for an incontinent person who does not excrete much, or is an auxiliary for a disposable diaper for adults. The present invention relates to an absorbent article that is used in combination with, and is used for men.

[0002]

2. Description of the Related Art Absorbent articles which are used as auxiliary materials for incontinence or adult diapers for men have an absorbent body inside and are already formed into a tubular shape or a bag shape. Etc. are provided. However, since such an absorbent article has a fixed size, has a feeling of pressure, and has a low absorption amount of body fluid such as urine, it cannot be applied to all wearers.

Another auxiliary absorbent article comprises a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber disposed between the two sheets, and the above-mentioned top. It is a belt-like material that can be folded back into a substantially bag-like or funnel-like shape with the sheet inside, and has at least a first side flap and a second side flap with the back sheet extending outward from both side ends of the absorbent body. What you have done is already known.

For example, as shown in FIGS. 4 and 5, a water absorbent article 70 includes a top sheet 72, a back sheet 74,
It consists of an absorber 76 sandwiched between both sheets 72, 74,
The absorbent body 76 has side flaps 78, 80 extending from the backsheet 72 and the topsheet 74 at both ends. The side flaps 78, 80 are provided with gathers 82a, 82b which are elastic members, and an adhesive tape 84 and a release paper 86 are provided at predetermined positions on the surface of the back sheet 74 (actual opening flat 2- No. 6024).

When such an absorbent article 70 is used for men, as shown in FIG. 5, the absorbent article 70 is used.
Is folded back into a bag shape or a funnel shape, and the end portion 70a of the absorbent article provided with the adhesive tape 84 is folded into the bag shape, and the absorbent article is substantially diagonally opposed to the absorbent article through the adhesive tape 84. ) It is adapted to be attached to the inner surface (top sheet surface) of the portion 70b. Such an absorbent article 70 has the advantages that the size can be adjusted according to the use state and the amount of whole body fluid such as urine is absorbed.

[0006]

However, in the conventional absorbent article, since the adhesive tape 84 is adhered to the surface of the top sheet 72, there is a problem that the adhesive force between them is weak. That is, the top sheet 72 is
The top sheet 72 weakens the adhesive force of the adhesive tape 84 because it is formed of a non-adhesive non-woven fabric, a porous film, or the like, and a silicone oil, paraffin wax, or the like is applied to the periphery thereof. There is a risk that the absorbent article may lose its shape when used for a long time.

Further, in the conventional absorbent article 70, the end portion 70a provided with the adhesive tape 84 is a portion 70 which is diagonally opposed.
When folded in b, gather 82 of side flap 80
There is a risk that b may disturb the operation. Further, since the folded and overlapped portions 70a and 70b are arranged on the side (or the side opposite to the skin side) with which the disposable diaper or the like comes into contact during wearing, as a result, the absorbent article in the diaper is There is a lack of positional stability, the fit is deteriorated during long-time wearing, and the gathers 82a of the side flaps 78, which are the opening edges of the formed bag or the like, directly contact the skin, so that the wearing feeling may be deteriorated.

Furthermore, since the side flaps 80 extend in the direction of exudation of liquid, it is difficult to suppress liquid leakage. Therefore, an object of the present invention is to provide a supplementary absorbent article that is easy to mount during use and does not have a risk of losing its shape during long-term use and that is used together with a disposable diaper or the like. ..

Another object of the present invention is to provide, in addition to the above objects, an absorbent article which is excellent in wearing feeling at the time of use and has little leakage of liquid such as urine.

[0010]

The present invention comprises a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorber disposed between the two sheets. An absorbent article that is a belt-like material that can be folded back into a substantially bag-like or funnel-like shape on the inside, and that has a first side flap and a second side flap at least with the back sheet extending outward from both ends of the absorbent body. Back sheet surface of the first side flap, in which the first side flap is folded back to the top sheet side, a part or all of the first side flap is fixed to the top sheet, and folded back An absorbent article, characterized in that an adhesive portion is provided on at least a part of the surface of the second side flap, and a stretchable elastic member is arranged along the flap in the central region of the second side flap. It is obtained by achieved by providing a.

[0011]

According to the absorbent article of the present invention, when the absorbent article is folded back into a bag shape or a funnel shape, the side end portion of the article without the elastic member is not contracted. The operation can be simplified. In addition, the end of the absorbent article provided with the adhesive section is folded with the part diagonally opposite to the inner side, so that there is no extra absorber left on the outside and the size of the opening can be freely selected. it can. In the adhesive portion, since the back sheets are joined together, a sufficient adhesive force is maintained and it is difficult to lose the shape. Furthermore, since the adhesive portion is located in the longitudinal direction, the overlapped portions are completely joined together and there is no leakage from this portion.

When the absorbent article shaped like a bag or a funnel is mounted, the overlapping portion of the absorbent article is
Since there is no elastic elastic member etc., when using it together with a disposable diaper, arrange the overlapping part so that it is in contact with the surface material,
When the absorbent article of the present invention is used alone like an incontinence person, the overlapped portion can be placed on the side in contact with the skin, and a stable feeling and fitting property occur during wearing.

Further, when the second side flap is folded back, particularly when both ends of the second side flap are fixed, the central portion of the second side flap rises,
It becomes a leak-proof wall at the opening of the bag-shaped or funnel-shaped absorbent article. Further, the elastic member of the second side flap is located on the upper portion, and the possibility of directly pressing the skin is reduced.

[0014]

Embodiments of the absorbent article according to the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of an absorbent article according to the present invention. FIGS. 1 (a) and 1 (b) are plan views of the absorbent article according to the embodiment, and FIG. 2 (a). 3B is a sectional view taken along the line I-I and a sectional view taken along the line II-II in the embodiment shown in FIG. 1, and FIG. 3 is a view showing a usage state of the absorbent article.

In the absorbent article according to this embodiment, as shown in FIG. 1, a liquid-permeable top sheet 2, a liquid-impermeable back sheet 3, and a sheet between the two sheets 2 and 3 are arranged. Is a belt-like material that is folded back into a bag shape or a funnel shape with the top sheet 2 inside, and the back sheet 3 extends outward from both side ends of the absorber 4.
And the first side flap 6 with the topsheet 2 extended
The configuration including the second side flap 7 is the same as that of the known absorbent article.

Thus, in the absorbent article according to this embodiment, as shown in FIGS. 1 to 3, the first side flaps 6 are folded back to the top sheet 2 side, and the first side flaps 6 are formed. A part or all of the above is fixed to the top sheet 2, and an adhesive portion 8 is provided on at least a part of the back sheet 3 surface of the folded first side flap 6.
In addition, a stretchable elastic member 9 is arranged along the flap in the central region of the second side flap 7.

Further, the second side flap 7 is folded back to the top sheet 2 side, and the front and rear ends of the second side flap 7 are fixed to at least the top sheet 2. Explaining this embodiment in more detail, as shown in FIG. 1, the absorbent article 1 is a strip having a constant width, and the widths of the topsheet 2 and the backsheet 3 are the absorbers 4.
Is formed longer than the width of. Then, both sheet portions extending from both side ends of the absorber 4 are fixed to each other and
And the second side flaps 6 and 7, and are folded back to the top sheet 2 side.

As shown in FIG. 2, the first side flap 6
All of the folded back inner surfaces are fixed to the topsheet 2 surface, and the backsheet 3 surface covers a part of the topsheet 2 surface (near the side end surface). Further, an adhesive tape 8 as an adhesive portion and a release paper 10 covering the adhesive tape 8 are provided on the surface of the first side flap 6 (backsheet 3 surface). The second side flap 7 is in a state in which both end portions of the folded back inner surface are fixed to the top sheet 2 surface, and the central portion thereof is not fixed. Further, a gather 9 which is a stretchable elastic member is attached to substantially the center of the second side flap 7.

As the above-mentioned fixing method, a known method can be adopted, and for example, adhesion by a hot-melt type adhesive, welding by ultrasonic waves, welding by heat, etc. can be appropriately used. Moreover, since the topsheet 2 surface of the absorbent article 1 of the present embodiment is an absorption surface for body fluids such as urine,
The top sheet 2 is a liquid-permeable sheet, the back sheet 3 is a liquid-impermeable sheet, and the absorber 4 is a holding carrier that holds water sufficiently.

That is, the top sheet 2 is a liquid permeable sheet that allows excrement to permeate into the absorbent body 4, and it is preferable that the top sheet 2 has a feeling close to that of underwear. As such a liquid permeable sheet, for example, a woven cloth can be used. , Non-woven fabric, porous film and the like are preferable. In addition, a silicone-based oil agent on the periphery of the top sheet,
Urine, etc. in the peripheral area is treated by applying water repellent treatment by applying a hydrophobic compound such as paraffin wax or by applying a hydrophilic compound such as alkyl phosphate ester in advance and washing the peripheral edge with warm water. Leakage due to bleeding may be prevented.

As the back sheet 3, a liquid-impermeable sheet having moisture permeability to allow vapor to pass therethrough, which is obtained by adding a filler to a thermoplastic resin, and a sheet having a feel similar to underwear,
For example, a strong water-repellent non-woven fabric, a composite material of a film and a woven fabric, or the like is used. As the absorbent body 4, it is preferable to use defibrated pulp as a main material together with a highly water-absorbent polymer, and in addition to that, a mixture of thermoplastic resin, cellulose fiber, and high-molecular-weight water-absorbent polymer to which heat treatment is applied is preferable. The high-molecular water-absorbing polymer may be present in any of the upper layer, the middle layer, and the lower layer of the absorbent body 4, or may be mixed with the defibrated pulp.

For incontinence persons, it is desirable that the thickness of the absorber 4 is also thin so that the appearance is not noticeable when worn.
Further, in order to use it together with a disposable diaper, it is desirable that the absorbent body 4 has a high absorption capacity, so that it is not necessary to frequently replace the diaper body. Further, in any of the above cases, it is desirable that the bending rigidity be small and that the bending feeling be good, and that the bending rigidity be small.

The gather, which is a stretchable elastic member attached to the second side flap 7, is not limited to a thread-shaped stretchable elastic member, and may be a tape-shaped member or flat rubber. Such a stretchable elastic member is
It is particularly preferable that the expansion / contraction stress at 100% elongation is 100 g or less, and it is also possible to use a yarn having absorption and expansion properties.

In the absorbent article of this embodiment constructed as described above, when the absorbent article 1 is used, it is folded back into a bag shape or a funnel shape with the surface of the top sheet 2 inside. In this case, since the side end portion (the side end portion having the adhesive tape 8) of the absorbent article 1 that is folded back to be tapered does not have a contracting action because it does not have a stretchable elastic member, the folding operation can be easily performed, and a predetermined operation can be performed. The shape can be easily adjusted.

In addition, the end portion provided with the adhesive tape 8 is folded at a portion substantially diagonally opposite to the end portion, and the adhesive tape 8 is provided on the outer surface of the diagonally opposite folded portion, that is, the back sheet 3 surface. Stick it. Therefore, the pressure-sensitive adhesive tape 8 is to be joined by superimposing the three surfaces of the back sheets. When the absorbent article 1 shaped like a bag or a funnel is mounted as described above, since the overlapping portion 12 does not have an elastic elastic member or the like as shown in FIG. 3, it can be placed on the side in contact with the skin. At the same time, since the gathers 9 are located above, the stability and fit in wearing, and the gathers 9 are prevented from directly touching the skin, and the feel is improved.

Further, the second side flap 7 is folded back with its both ends fixed to the surface of the top sheet 2, and the central part other than both ends where the gather 9 is raised rises from the inside of the bag-like shape and the leak-proof wall. Becomes In the above embodiment,
The first side flap 6 and the second side flap 7 are
The top sheet 2 and the back sheet 3 were extended and overlapped and joined together.
Only the first side flap 6 or the second side flap 7 may be formed by extending only one side.

When the first side flap 6 is folded back and fixed to the surface of the top sheet 2, the entire side flap 6 is fixed in the above embodiment, but the fixed portion need not be the whole and is provided in a proper place. Just do it. When the second side flap 7 is folded back and fixed to the surface of the top sheet 2, it is desirable to use both end portions of the side flap 7 as fixing portions as in the above-mentioned embodiment, but even if the whole is fixed, a predetermined leakage prevention is performed. You can get sex.
