Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sanitary napkin.
[0002]
[Prior art]
Conventionally, a napkin used by sticking an adhesive area formed on the back surface of a sanitary napkin to a crotch area of a wearing short is well known.
[0003]
[Problems to be solved by the invention]
In the known napkin, when the wearing short is lowered, the napkin is lowered together with the napkin, and the napkin may be separated from the vaginal opening and the periphery thereof to cause menstrual leakage.
[0004]
An object of the present invention is to eliminate menstrual leakage due to such a cause.
[0005]
[Means for Solving the Problems]
The present invention for solving the above-mentioned problems includes both end edges that extend in the width direction and are positioned on the front and rear sides of the wearing shorts in the wearing state, and both side edges that extend in the front-rear direction along both edges around the legs of the wearing shorts. A sanitary napkin having a portion,
A pair of elastic members extending in the front-rear direction in the front-rear direction from the respective width-direction central portions of the both end edges and extending the center region of the napkin from the wearing shorts by the contraction property. Each of the pair of elastic members has a proximal end portion and a distal end portion, and is joined to each of the both end edge portions of the napkin at the proximal end portion, and a wearing shorts contact surface of the distal end portion Is characterized in that an adhesive zone is formed .
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The details of the sanitary napkin according to the present invention will be described with reference to the accompanying drawings as follows.
[0007]
FIG. 1 is a perspective view of a sanitary napkin 1 that is curved for attachment to wearing shorts. When the napkin 1 is worn, the napkin 1 has both end edges 2 extending in the width direction located on the front and rear sides of the wearing shorts, and both side edges 3 extending in the front-rear direction along the leg periphery edges. the central region 4 surrounded by the edge portion 2 and the side edges 3, menstrual blood absorber for a conventionally well-known are formed to those skilled in the art.
[0008]
From the end edges 2, respectively in the width direction central portion of the napkin 1, extends the elastic member 5 having stretchability in the longitudinal direction. The elastic member 5 has a base end portion 5A and the remaining portion including the distal end portion 7, the width of the elastic member 5 is in the range of 1/5 to 5/5 of the width of the napkin 1, and its length Saga, can reach 30~300mm during elongation, in which the return stress at that time is made from a sheet material that is adjusted to be 30 to 500 g, base portion 5A, the width of the tip portion It is larger than 7 and is bonded to the back surface of the napkin 1. An adhesive region 6 is formed on the wearing shorts contact surface of the distal end portion 7 of the elastic member 5 by applying an adhesive. The tip 7 may be the same as the member 5, but is preferably formed by joining a non-stretchable sheet piece to the member 5. Although not shown, the adhesive area 6 is covered and protected by release paper, and is peeled off when the napkin is used.
[0009]
The napkin 1 having such a configuration has the back surface (the lower surface in the figure) of the central region 4 curved as shown in the figure and applied to the crotch portion of the wearing shorts, and the elastic members 5 at the front and rear are respectively extended to form the adhesive region 6. Fasten on the inner side of the wearing shorts. After fastening, the napkin 1 moves so that the central region 4 is lifted upward from the crotch portion of the shorts by the contraction of the elastic member 5 and approaches the wearer's body. Therefore, even when the worn shorts are lowered, the napkin can maintain a close contact with the body, and menstrual blood does not leak.
[0010]
In the figure, although the respective respectively and the elastic member 5 of the edge portion 2 are indicated by the same shape, it is also possible to these shapes embodying the present invention in different embodiments.
[0011]
As the elastic member 5, an elastic stretchable rubber sheet, a plastic sheet, a nonwoven fabric, or the like can be used.
[0012]
【The invention's effect】
The sanitary napkin according to the present invention floats from the crotch of the wearing short by using the elastic member and moves so as to approach the wearer's body, so that menstrual blood does not leak even when the wearing short is lowered.
