[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary napkin for absorbing and retaining menstrual blood.

[0002]

2. Description of the Related Art Conventionally, in a sanitary napkin, in order to prevent so-called lateral leakage of menstrual blood, liquid-resistant flaps are respectively disposed on both sides of a menstrual blood absorbing surface, and pockets for receiving menstrual blood are provided. What is formed between the flap and the menstrual absorption surface is known.

However, due to the arrangement of the liquid-resistant flap,
The area of the menstrual absorption surface becomes smaller, and menstrual blood may flow on the surface of the flap to its outer edge and leak laterally. Also,
Since the pocket does not open sufficiently, menstrual blood cannot be introduced into the pocket and cannot be received. In this respect, menstrual blood may leak laterally.

[0004]

According to this invention, the area of the menstrual blood absorbing surface is not reduced and the pockets are sufficiently opened despite the placement of the liquid-resistant flaps on both sides of the menstrual blood absorbing surface. It is a subject to be configured in such a manner.

[0005]

According to the present invention, a liquid-resistant flap is provided on the upper surface of both sides of a laminate having a liquid-absorbent panel interposed between a liquid-permeable inner sheet and a liquid-impermeable outer sheet. Assuming that the sanitary napkins are arranged respectively, the following features are characteristic.

That is, a part of the outer sheet and both of the flaps is extended outward at a portion deviated to the front end of the laminated body to form a wing portion, and both the wing portion including the laminated body and the both wing portions are formed. Join the outer edge of the flap,
The distance between the inner edges of the two flaps in the front and rear regions of the laminate located before and after the intermediate region is greater than the distance between the inner edges of the two flaps in the intermediate region of the laminate. A string attached along the inner edges of the flaps in the area.

[0007] In a preferred embodiment, the cord includes an elastic body, which is covered with an inner edge of the flap in the intermediate region.

[0008]

The napkin according to the present invention having the above-described structure is:
Both wings are folded back and fixed to the lower surface of the crotch pad of the shorts to be used. When the two wings are folded in this way, the two flaps in the intermediate region where the two wings are located are pulled outward by the two wings and rise, and the facing distance between the two flaps is increased, and the both flaps and the menstrual blood are absorbed. The pocket in the intermediate region formed between the surface and the surface is sufficiently opened, the menstrual blood absorbing surface in the intermediate region is sufficiently secured, and menstrual blood that has flowed and diffused in the lateral direction on the menstrual blood absorbing surface has both flaps in the intermediate region. Or, on the other hand, leakage to the outside is prevented. The front and rear regions have a smaller amount of menstrual blood flowing and diffusing in the lateral region than the intermediate region, but also have a sufficient menstrual absorption surface in the front and rear regions. Although the flaps are also located in the front and rear regions, the menstrual absorption surface defined by the inner edges of the flaps is, as described above, larger than the opposing interval between the two flaps in the intermediate region where the opposing interval is enlarged. Because it is not narrow.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of a napkin according to the present invention will be described below.

As shown in FIGS. 1 and 2, a liquid-permeable inner sheet 1, a liquid-impermeable outer sheet 2 formed to have a larger width, and a liquid-absorbing panel interposed between these sheets. 3 form a laminate 4. Base flaps are formed by extending the inner and outer sheets 1 and 2 outward from the outer peripheral edge of the panel 3. Of these base flaps, those 5 on both sides extend further outward in the inner and outer sheet portions 1a and 2a extending outward from the side edges of the panel 3 and the intermediate region 6 of the laminate 4 biased toward the front end. It is formed from the outer sheet portion 2b that has been put out.

On the upper surface of both sides of the laminated body 4, liquid-resistant flaps 9 each having a portion 9a extending in the same shape and the same size as the outer sheet portion 2b are arranged. The outer peripheral edge of the laminated body 4 and the side edges and longitudinal ends of each flap 9 are joined by an adhesive or a fusion means, so that each flap 9 and the inner sheet 1 are joined.
The pocket 17 is formed between the outer sheet portion 2b and the outer sheet portion 2b, and the wing portion 10 is formed from the extended portion 9a of the flap 9 joined to the upper surface thereof. The inner portion 9b of each flap 9 in the intermediate region 6 is folded back to the lower surface, and the cord 11 is placed inside the folded line.
, And the inner edge 12 is located on the upper side inside the side edge of the panel 3. Front and rear regions 7 of the laminate 4,
8, the inner portion of each flap 9 is cut away, so that the inner edge 13 of each flap 9 in the front region 7 and the rear edge thereof are larger than the inner space 12 of each flap 9 in the intermediate region 6. The facing distance between the inner edges 14 of the flaps 9 in the side region 8 is large.

As shown in FIG. 3, an adhesive portion 15 and a wing portion 10 extending in the vertical direction
Adhesive portions 16 are provided on the lower surface of each of them, and these are covered with release tapes 17 and 18 to protect them.

In the napkin constructed as described above, the lower surface, which is the non-menstrual absorbing surface, abuts against the inner surface of the crotch pad of the shorts to be worn and is fixed by the adhesive portion 15, and each wing section 10 is further attached to the crotch pad. It is folded back to the lower surface of the part and fixed to the lower surface with an adhesive surface 16 for use. Thus, the wing section 10
Is folded back, the two flaps 9 in the intermediate region 6 are pulled outward by the respective wing portions 10 to increase the facing distance therebetween, and the pocket 17 is fully opened.

A nonwoven fabric or a porous plastic sheet is used for the inner sheet 1, a plastic sheet is used for the outer sheet 2,
The panel 3 may be made of a mixture of fluff pulp and superabsorbent polymer particles, the flap 9 may be made of a non-woven fabric subjected to a water-repellent treatment, and the cord 11 may be made of an elastic material.

[0015]

According to the napkin according to the present invention having the above-described structure, the napkin has the above-mentioned action, and thus has a liquid-resistant flap on both sides of the menstrual absorption surface. The pocket in the region is sufficiently opened, and the menstrual blood absorbing surface is sufficiently secured, and the menstrual blood absorbing surface in the front and rear regions is also sufficiently secured, so that lateral leakage of menstrual blood can be prevented. In addition, since the inner edges of the flaps attached to the inner edges of both flaps in the intermediate region are raised, menstrual blood leaks outside the raised inner edges even if the pocket may not be opened. Less is.

Since the string is an elastic body, even if the user's skin is pressed against the inner edges of both flaps on which the string is located, the user does not feel uncomfortable.
