Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to sanitary disposable shorts.

Conventional technology In conventional disposable shorts, the body part is sewn with a fabric that can withstand repeated use through washing, and an inner crotch piece made of fabric coated with an impermeable material is layered and sewn to the crotch area. . When worn during menstruation, a body fluid disposal device (sanitary napkin) is glued to the inner crotch piece.

Conventionally, disposable shorts have been provided that are made of paper or synthetic fiber nonwoven fabric and are sewn using a flexible disposable material.

Problems to be Solved by the Invention However, with the conventional menstrual shorts mentioned above, when the inner crotch area becomes dirty due to fluid exuded from the body fluid treatment device, it must be washed each time, which is not only extremely troublesome, but also Stains caused by body fluids are difficult to remove even when washed. For this reason, it feels unclean when worn, and cannot withstand long-term use. These sanitary shorts are expensive and therefore uneconomical. Also, if you have a menstrual period while traveling, you will need to carry multiple sanitary shorts with you.
Since it is expensive as mentioned above, it is uneconomical.

On the other hand, although the above-mentioned conventional disposable shorts have a double-layered groin area, they cannot be used during menstruation because body fluids that seep out from the body fluid treatment device seep out from the groin area and stain clothing such as skirts and pants. .

In addition, in any of the above shorts, the crotch area is formed by forming two inner and outer crotch pieces separately from the front body piece and the back body piece, and overlapping these two crotch pieces and sewing the side edges. After that, these front and rear edges are sewn to the front body and the back body, so not only is the molding work troublesome, but also the sewing work is time-consuming.

Therefore, the present invention is an attempt to solve the above-mentioned conventional problems. It does not require washing, it can reliably prevent the body fluid exuded from the body fluid disposal device from seeping out, and it is moldable. It is an object of the present invention to provide disposable sanitary shorts which can be easily removed and sewn, and which are also more economical.

Means for Solving the Problems The technical means of the present invention for solving the above problems is that the front body and the crotch piece, and the back body piece and the crotch piece are connected to each other using a single piece of flexible material. The side edges of the front body piece and the back body piece were sewn together, and both crotch pieces connected to the front body piece and the back body piece were placed on the thin and flexible body fluid absorbing material and on the outside thereof. They are layered with a thin, flexible, water-impermeable sheet material interposed therebetween, and the crotch piece, body fluid absorbent material, and sheet material are sewn together.

Effect The effects of the above technical means are as follows.

Since it is disposable, there is no need to wash it. In addition, even if body fluid oozes out from the body fluid disposal device, it will be absorbed by the body fluid absorbing material interposed between the two layers of groin pieces, and the exuded body fluid will be absorbed by the body fluid absorbent material interposed between the two layers of groin pieces. It is possible to reliably prevent the body fluid exuded from the body fluid treatment tool from leaking outside by reducing the amount that reaches the water-permeable sheet material to the outside, and to prevent staining of clothing such as skirts and pants. In addition, since the crotch piece is connected to the front body piece and the back body piece and each is formed from a single piece of material, molding and sewing work can be easily performed.
It can be manufactured at low cost.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figures 1 to 5 show an embodiment of the present invention, with Figure 1 being an exploded view, Figures 2 and 3 being a front view during manufacture, and Figure 4 being a complete state. FIG. 5 is a partially cutaway front view of the stretched state, and FIG. 5 is an enlarged longitudinal sectional view of the stretched state.

As shown in FIG. 1, a front body piece 1 and a crotch piece 2 are connected by a disposable material such as a sheet of paper or a nonwoven fabric made of synthetic fibers. The back body piece 3 and the crotch piece 4 are also made of a single piece of disposable material similar to the above. This disposable material is a material used in conventional disposable shorts, and is flexible and feels good against the skin, and has numerous ventilation holes formed throughout. The body fluid absorbing material 5 is made of a nonwoven fabric made of synthetic fibers, etc., and is thin and flexible. For example, Benliese Super Rub (trade name) manufactured by Asahi Kasei Corporation is used. The water-impermeable sheet material 6 is
For example, a film made of a water-impermeable material such as polyethylene is laminated onto a material similar to the above-mentioned disposable material, and is thin and flexible. This water-impermeable sheet material 6 can also be made of materials used in conventional body fluid treatment tools. Then, as shown in FIG. 2, the side edges of the front body piece 1 and the back body piece 3 are sewn together,
As shown in FIG. 3, the crotch piece 2 connected to the front body piece 1 is on the inside, and the crotch piece 4 connected to the back body piece 3 is on the outside, and these crotch pieces 2 and 4 are connected to the body fluid absorbing material 5. and a water-impermeable sheet material 6 interposed therebetween, and the front edges of these crotch pieces 2, 4, body fluid absorbent material 5, and water-impermeable sheet material 6 are sewn together, as shown in FIGS. 4 and 5. As shown in the figure, both side edges of the crotch pieces 2 and 4, the body fluid absorbent material 5, and the water-impermeable sheet material 6 are sewn with elastic thread 7, and this elastic thread 7 connects the front body piece 1 and the rear body piece 1. It is sewn along the edge of the body piece 3. This gives stretchability to the foot insertion/removal section 8. Front body piece 1 and back body piece 3
The upper edge of is folded inward, and a rubber tape 9 is inserted and sewn to give elasticity. The disposable sanitary shorts constructed in this way is shrunk to a small size as a whole due to the elastic thread 7 and rubber tape 9, but in order to make it easier to understand, it is shown in an enlarged state in Figures 4 and 5. It is shown in

When the sanitary disposable shorts having the above structure is worn, an adhesive tape provided on the body fluid treatment device is adhered to the inside of the groin piece 2. Even if body fluid associated with menstruation oozes out from the body fluid treatment device, this should be removed from the groin pieces 2 and 4.
The body fluid absorbed by the body fluid absorbing material 5 interposed between the groin pieces 2 and 4 can similarly reach the impermeable sheet material 6 interposed between the groin pieces 2 and 4 in a very small amount. The water-permeable sheet material 6 eliminates the risk of leakage not only to the outside but also from the sides of the water-impermeable sheet material 6. Therefore, leakage of body fluids can be reliably prevented. If the inner crotch piece 2 becomes soiled due to exudation of bodily fluids, new sanitary shorts should be worn. As a result of the wearing test,
Even if the body fluid treatment equipment was replaced, it was confirmed that it could withstand the strength for one day.

Note that the front body piece 1, the crotch piece 2, the back body piece 3, and the crotch piece 4 do not necessarily have ventilation holes throughout.
Further, rubber tape may be sewn onto the leg insertion/removal portion 8. The present invention can be modified in various other ways without departing from its basic technical concept.

Effects of the Invention As is clear from the above description, the present invention is disposable and does not require washing. In addition, even if body fluid oozes out from the body fluid treatment device, it will be absorbed by the body fluid absorbing material interposed between the two layers of groin pieces, and the exuded body fluid will be absorbed by the body fluid absorbent material interposed between the two layers of groin pieces. The amount that reaches the water-permeable sheet material is very small, eliminating the risk of body fluids seeping out not only from the water-impermeable sheet material but also from the sides, and body fluids seeping out from the body fluid treatment device to the outside. It is possible to reliably prevent the liquid from seeping into the skin, and to prevent soiling of clothing such as skirts and pants. In addition, since the crotch piece is connected to the front body piece and the back body piece and each is formed from a single piece of material, molding and sewing work can be easily performed, and furthermore, manufacturing can be done at low cost. is possible and economical.
