DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a pad for menstrual blood treatment,
Related to female incontinence pads .

[0002]

2. Description of the Related Art Conventionally, in order to reduce the feeling of wetness when wearing this kind of pad , there is known a technique of making only a central portion of a skin contact surface liquid-permeable and a peripheral portion thereof liquid-impermeable. is there. For example, JP Utility Model 59-25374, in pad menstrual blood processing, a technique for performing a sequential densely waterproof toward the outer circumferential region from the central portion of the menstrual blood absorption surface is disclosed.

[0003]

According to the above-mentioned prior art, menstrual blood absorbed in the core is blocked by the waterproofed portion when flowing backward, and the reverse flow to the upper surface of the pad is reduced accordingly. , The feeling of wetness can be reduced. However, with this pad, the area that allows liquid permeation on the skin contacting surface is narrowed, and on the contrary, absorption is slowed by that amount, and menstrual blood flowing out of the central part is no longer absorbed by the core. However, there is a problem that the wet feeling is rather increased.

[0004] It is an object of the present invention to solve the above-mentioned problem by providing a pocket made of an end flap that opens toward the opposite end at the end of the pad.

[0005]

[MEANS FOR SOLVING THE PROBLEMS]
Means of the invention are as follows.

[0006] The present invention provides a pad book having a liquid-absorbent core interposed between a liquid-permeable top sheet and a liquid-impermeable back sheet.
A body, and the topsheet is provided at a peripheral portion of the main body.
A liquid-resistant flap to be coated is joined to the periphery and
Menstrual treatment to form a pocket opening towards the center
Or, it is an improvement of the pad for female incontinence .

A feature of the present invention according to the improvement is that the liquid resistance
Sex flaps are located on both lateral edges of the body
A pair of elastic side flaps and the side flaps
Separately and larger than the width dimension of the side flap
The body is formed to have a vertical dimension, and both ends of the main body in the vertical direction
The vertical end portions of the side flaps are
And a pair of end flaps arranged to cover
It is composed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The body fluid absorbent article according to the present invention will be described below in detail with reference to the accompanying drawings, taking a pad for menstrual treatment as an example.

FIGS. 1 and 2 are a partially cutaway perspective view and a sectional view taken along line 2-2 of a pad 1 for menstrual blood treatment . Pad 1 is
The upper surfaces of the front and rear end portions 10 and 11 of the pad body 6 including the liquid-permeable top sheet 3, the liquid-impermeable back sheet 4, and the liquid-absorbent core 5 interposed between the sheets 3 and 4 are paired. D
The top sheet is exposed at a central portion 12 between both end portions 10 and 11.

The front and back sheets 3 and 4 and the end flap 7 are joined to each other at a portion extending from the peripheral edge of the core 5 by a fusion line 8, and the end flap 7 is free edge 13 near the center 12. , And form a pair of pockets 15, 16 each opening toward the ends 10, 11. The depth of each of the pockets 15 and 16 in the front-back direction of the pad 1 is ４ to ３ of the entire length of the pad 1, and therefore, between the open edges of the pockets 15 and 16,
The length of the central portion 12 where the topsheet 3 is exposed is 1/1 of the entire length.
It is in the range of 2/3.

In such a pad 1, it is preferable to use a nonwoven fabric or a perforated plastic film for the top sheet 3 and a plastic film for the back sheet 4. The end flap 7 means a gas-permeable or non-gas-permeable liquid-impermeable or liquid-impermeable sheet. For example, a known plastic film having gas-permeable fine pores in addition to a conventional plastic film is used. be able to. Also,
These plastic films can be replaced with nonwoven fabrics. The core 5 may be made of ground pulp or a mixture of ground pulp and a superabsorbent polymer. If any of the sheets 3, 4 and the end flap 7 are non-fusible, the fusing line 8 can be replaced with a bonding line using a hot melt adhesive or the like.

The pad 1 constructed as described above has a central portion 1
2 is used in contact with the vaginal opening. In addition to being absorbed into the core 5 at the central portion 12, menstrual blood enters pockets 15 and 16 and is absorbed into the core 5 therefrom. In the pad 1, when the body pressure acts, the absorbed menstrual blood may flow back to the upper surface of the topsheet 3, but in the front and rear portions 10, 11, the menstrual blood is blocked by the end flap 7 and the wearer's skin is blocked. Never touch.

In the pad 1, when an elastic sheet extending in the width direction of the pad 1 is used as the end flap 7, the pad 1 is bent in the width direction and the pocket 15,
The large opening 16 can facilitate the inflow of menstrual blood. In addition, an elastic member can be attached to the free edge 13 in an extended state instead of the elastic sheet. Endow
The wrap 7 may be provided only on one of the front and rear sides of the pad 1, so that the exposed area of the topsheet 3 can be increased.

FIG. 3 is a partially cutaway perspective view of the sanitary pad 1 in a mode different from that of FIG. A pair of side flaps 20 are attached to the upper surface of the topsheet 3 on both left and right sides of the pad 1, and an end flap 7 is on the side flap 20. The end flap 7 is clear from the figure.
If the vertical dimension is larger than the width of the side flap 20
It is formed large. The top- and backsheets 3, 4, rhinoceros
And de flap 20, and the end flaps 7, are integrally joined by pad 1 peripheral weld line 8. The side flaps 20 have shrinkage due to the action of an elastic member 21 having an outer edge fixed by the welding line 8 and an unfixed inner edge adhered thereto in an extended state. Therefore, when the pad 1 is bent in the front-rear direction, the side flaps 20 tend to rise from the topsheet 3, and together with the topsheet 3, form a pocket 22 that opens toward the inside of the pad 1. Since the side flaps 20 push up the end flaps 7 when standing up, the pockets 15 and 16 at the front and rear end portions are greatly opened to facilitate the inflow of menstrual blood.

[0015]

The pad according to the present invention has two ends of the main body.
Place end flaps that form pockets in each of the
At the same time, end flaps on each side edge of the body
An end flange that lifts up to facilitate the formation of the pocket.
Side flange with a width smaller than the vertical
The pads are located so that the pad can absorb
Without reducing the body, together with the end flap
It reduces dirt on the menstrual absorption surface due to
Leakage from the edge can be prevented.

[0016] The end flaps in case of having a stretchability which is extended in the width direction of the pad body, the flow of fluid is facilitated by easier said pocket is larger opening.
