[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, flaps are respectively arranged on the upper surfaces 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 a sanitary napkin, it has the following features.

That is, a part of the outer sheet and both of the flaps is extended outward at a position deviated to the front end side of the laminate to form a wing portion, and the laminate and the both wing portions are included. The outer peripheral edges of both flaps are joined, and while the two flaps in the middle region of the laminate are given liquid resistance, the two flaps in the front and rear regions of the laminate are given liquid permeability, A string attached along the inner edges of the flaps in the middle area.

In a preferred embodiment, the provision of the liquid permeability of both flaps is performed by providing a large number of openings in the front and rear flaps. A point that the two flaps in the front and rear regions are subjected to a hydrophilic treatment, and a point that the cord-like material is an elastic body and is covered with an inner edge of the flap in the intermediate region. including.

[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. This is because the flaps are located in both the front and rear regions, but the front and rear regions are provided with liquid permeability.

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 to 3, a liquid-permeable inner sheet 1, a liquid-impermeable outer sheet 2 having a larger width, and a liquid-absorbing panel interposed between the 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 laminate 4, 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 two flaps 9 shown in FIG. 1 provide liquid resistance in the intermediate region 6 of the laminate 4, while the front and rear regions 7 and 8 have a large number of apertures 1.
By providing 2, liquid permeability is provided. The two flaps 9 shown in FIG. 2 impart liquid resistance in the middle region 6 of the laminate 4, while imparting liquid permeability in the front and rear regions 7 and 8 by performing a hydrophilic treatment. It is. The outer periphery 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 a pocket 17 is provided between each flap 9 and the inner sheet 1 (menstrual absorption surface). The wing portion 10 is formed from the outer sheet portion 2b and the extended portion 9a of the flap 9 joined to the upper surface thereof. Inner part 9 of each flap 9 in the intermediate area 6
b is folded back to the lower surface, and the cord 11 is interposed along the folded line, and the inner edge 18 is positioned above the side edge of the panel 3.

As shown in FIG. 4, on both sides of the lower surface of the laminate 4, an adhesive portion 13 and a wing portion 10 extending in the longitudinal direction thereof are provided.
Adhesive portions 14 are provided on the lower surface of each of them, and these are covered with release tapes 15 and 16 to protect them.

In the napkin constructed as described above, the lower surface, which is a non-menstrual non-absorbing surface, is in contact with the inner surface of the crotch pad of the shorts to be worn and is fixed with the adhesive portion 13, and each wing portion 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 114 for use. Thus, the wing part 1
When 0 is folded back, both 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 hydrophobic film or a hydrophobic fiber nonwoven fabric, and the string 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.
