Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a sanitary napkin.

[0002]

2. Description of the Related Art Conventionally, sanitary napkins have been made by applying an adhesive to the outer surface of the leak-proof sheet of the napkin body to form a fastening portion to the inner surface of the shorts, and the surface of the fastening portion is made of paper. It is covered with release paper. Also, the napkin body was placed inside, and the napkin body and release paper were folded back in three or four in the lengthwise direction, and the folded napkin body and release paper were individually packaged in individual packaging bags. .

[0003]

However, although the conventional sanitary napkin is formed by folding back the napkin body and the release paper, the individual packaging shape is large and bulky. Therefore, when the sanitary napkin is to be stored in a bag such as a small case or a pochette, it occupies a large storage space in the bag, which makes it inconvenient to carry.

In this conventional sanitary napkin,
It is considered to increase the number of times the napkin body is folded. In this method, the napkin body is made small by arranging the folding parts in parallel and folding the napkin body a plurality of times, and then folding the napkin body in a direction intersecting the folding parts. However, this method has never been implemented.
Because the release paper made of paper is folded back several times in parallel, and then folded back in the direction intersecting with the folding side,
The folds are hard and deformed, and the folds of the hardened release paper may come into contact with the napkin body, damaging the napkin body. In addition, when using a conventional sanitary napkin, take out the napkin body and empty the individual bag,
The release paper peeled off from the fixing portion becomes dust, and it is troublesome to process both of these dusts.

The present invention is intended to solve the above-mentioned problems, and the sanitary napkin can be individually packaged in a small size as compared with the conventional method.
There is no damage to the napkin body. Therefore, when it is stored in a bag such as a small case or a pochette, it does not occupy a large storage space in the bag and can be carried easily. Further, it is intended to reduce the amount of dust generated during use and simply dispose of the dust.

[0006]

In order to solve the above-mentioned problems, the present invention provides a body fluid-absorbing absorbent layer between a water-permeable surface sheet and a water-impermeable leak-proof sheet. The napkin body is formed, the outer surface of the leak-proof sheet of the napkin body is formed with a fastening part to the inner surface of the shorts, and the release treatment surface that contacts and covers the surface of the fastening part is wider than the napkin body. Of the individual packaging film, the individual packaging film and the napkin main body are placed inside the napkin main body from both end sides in the lengthwise direction and folded back, and then the individual packaging film is further intersected with the folding side. The napkin body is folded back inward, and the tip of the folded back is fixedly formed.

Further, the fastening of the tip portion of the folded back may be performed by laminating the tip portion in parallel with the napkin body.

Further, the fastening of the tip portion of the folded back piece may be performed by raising the tip portion at a right angle to the napkin body.

The tip of the folded back may be fixed with an adhesive tape.

The tip of the folded back may be fixed by applying an adhesive.

Further, the fixing of the tip portion of the folded back may be performed by heat fusion.

[0012]

Since the sanitary napkin before use is configured as described above, the individual packaging shape is smaller and more compact than the conventional individual packaging method in which folding is performed a plurality of times only in parallel. Is formed. Therefore, the accessory case,
When it is stored in a bag such as a pochette, it does not occupy a large space for storing the bag and enables easy carrying.

Further, since the individual packaging film, which is thinner than the release paper, is arranged on the side of the fastening portion without using the release paper, the folds of the napkin body are folded parallel to each other and intersect the fold sides. Even if the folding part is formed in the direction of the arrow, unlike the conventional method, the intersecting part of the folding becomes hard and there is no possibility of damaging the napkin body.

Further, since the sanitary napkin before use is formed by individually compactly packaging it, it is possible to hold the sanitary napkin in the hand so as not to be seen by others without being folded back. Therefore, it becomes possible to protect the privacy of the user.

When a sanitary napkin is used,
After the fastening of the tip of the folded back is released, the napkin body and the individual packaging film are expanded to the outside, and all folded portions are stretched. Further, after the release-treated surface of the individual packaging film is peeled from the fastening portion, the fastening portion is fastened to the inner surface of the shorts and the napkin body is attached to the inner surface of the shorts. By this mounting, the individual packaging film peeled from the fastening part becomes dust,
As compared with the conventional method of discarding the release paper and the individual packaging bag, the amount of dust generated is small and the dust can be easily discarded.
Also, the individual packaging bag can be used for packaging and discarding the used napkin body.

Further, the fastening of the tip end portion of the folded back may be carried out by laminating the tip end portion in parallel with the napkin body or by raising the tip end at a right angle to the napkin body. It is also possible to do by.

Also, if the tip end of the folded back is fixed with an adhesive tape, both sides can be easily fixed. In addition, when opening both sides, the adhesive tape can be peeled off and easily opened.

If the tip end of the folded back is fixed by applying an adhesive, the amount of the material used for the fixing can be reduced and the cost can be reduced.

Further, if the tip end of the folded back is fixed by heating and fusion, the material for the fixing is unnecessary, and the cost can be further reduced.
