DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary napkin in an individual bag, and more particularly, to a napkin that can be easily removed from an individual bag.

[0002]

2. Description of the Related Art In a sanitary napkin described in Japanese Utility Model Laid-Open Publication No. Hei 7-33314, a side flap formed on each side edge in the width direction of a liquid-absorbent core has first and second sides extending from the flap. It has a second wing. The first wing is biased toward the front end of the napkin, and the second wing is biased toward the rear end of the napkin. On the back surface of the napkin, an adhesive is applied to a central portion in the width direction of the napkin and both first wings in the width direction, and the adhesive in the central portion allows the napkin to be fixed to the inner surface of the shorts crotch region where the napkin is worn. The first wing is bent at the side edge of the shorts crotch region, overlaps the outer surface of the shorts, and is fixed to the outer surface by an adhesive. The first wing covers the shorts side edge so as not to be soiled, and also prevents deformation such as twisting of the napkin. The second wing covers the hips of the shorts widely so that menstrual blood flowing in the hip direction of the wearer does not stain the shorts. When such a known napkin is sealed in an individual bag, the first and second wings are bent inside the napkin so as to overlap the topsheet,
The adhesive of both first wings is covered and protected by a first release paper hanging on both wings, and the adhesive at the center of the napkin is covered and protected by a second release paper. The napkin is folded in three in the front-rear direction so that the front end is on the top and the rear end is on the bottom with the top sheet inside.

[0003]

The known napkin does not move back and forth and right and left in the crotch region of the shorts by fixing the widthwise central portion to the inner surface of the shorts worn.
Menstrual blood can be captured accurately. However, since the second wing that spreads in the width direction is not fixed to the shorts, the second wing is twisted or broken by the movement of the hip of the wearer and does not perform its original function, or hinders a good feeling of wearing. And so on. In addition, when the napkin is worn, an operation of removing the napkin from the individual bag and an operation of sequentially peeling off the release paper one by one are necessary, and the individual bag and the first and second release papers are required. Each is a separate piece of waste and requires a lot of effort, such as having to discard at least three pieces of waste.

Accordingly, the present invention is to provide a napkin having the first and second wings, such as the above-mentioned known napkin, in which each wing can easily exhibit its original function, and the napkin can be easily taken out of an individual bag. Is an issue.

The material has a size extending from the periphery of the folded napkin, and the first and second wings each have an adhesive area individually formed on the back surface thereof. The two adhesive areas of the second wing are covered with the second release paper by one release paper, and the first and second release papers are fixed to each other in a portion where the napkins are folded in three layers, And the first release paper is fixed to the inner surface of the sheet material at a portion extending rearward from a rear end of the napkin.

In one preferred embodiment of the present invention, the sheet material constituting the individual bag extends from the left and right side edges of the napkin folded in three layers and is releasably joined at the overlapping portions. The first release paper has higher rigidity than the sheet material, extends rearward from the rear end of the napkin folded into the three layers, and is fixed to the inner surface of the sheet material, and It also extends rearward from the rear end of the sheet material.

In another embodiment of the present invention, the first and second release papers are constituted by a single common release paper.

In still another embodiment, the napkin has an adhesive area on the lower surface of the back sheet at the center in the width direction of the napkin separately from the adhesive areas of the first and second wings, The adhesive area is separate from the first and second release papers, and is covered by a third release paper fixed to the inner surface of the sheet material.

The fourth release paper 51 differs from the fourth release paper 51 in that it is a surface to be fixed.

In the sanitary napkin with individual bags shown in FIG. 8, one relatively long fifth release paper 52 is used in place of the first and second release papers 31 and 32. One surface of the fifth release paper 52 serves as a surface covering the first and second adhesive areas 26 and 27 and also serves as a surface fixed to the inner surface of the individual bag 3.
In the arrangement intervals of the first and second eigs 23 and 24 as shown in the illustrated example, the amount of release paper used may be larger than those in FIGS.

[0023]

According to the sanitary napkin in an individual bag according to the present invention, since the second adhesive region is formed on the second wing covering the hip portion of the shorts to be worn, the second wing can be prevented from being displaced or twisted. . The first and second adhesive areas separately formed on the first and second wings are covered and protected with separate first and second release papers, respectively, and the first and second release papers are fixed to each other and the first release is performed. By fixing the paper to the individual bag, the individual bag opening operation and the first and second release paper peeling operations become continuous operations. Since the first release paper uses a sheet material having higher rigidity than the plastic film of the individual bag, and the rear end of the release paper is extended rearward from the rear end of the individual bag to form the holding portion. In addition, it becomes possible to quickly open the individual bag. Since the individual bag and the release paper become one fixed to each other and come off the napkin, there is no trouble in disposing of this as garbage.
