However, the above-mentioned package has the following problems. In the above-mentioned package, the wrapping material for wrapping the napkin is a single film, so that the peeling property decreases with time, and the wrapping material is stretched or torn when the napkin is taken out. Further, if the film thickness is increased in order to suppress this, not only the cost will be increased, but also the film itself will be hard and the package cannot be easily opened. In the above packaging, the film strength is low, there is a problem of stretching or tearing when peeling the packaging material, also, if the peeling degree of the film is increased to solve such a problem, The water solubility is impaired and the toilet bowl becomes clogged when it is discarded. In the above package, since the adhesive layer can be provided only on a part of the napkin, the fixability is poor when the napkin is used. In the above-mentioned package, perforations are provided, but since air easily enters from the perforations and the package expands, it is difficult to carry or open. In the above and the above packaging, since the content or copolymer of the peeling substance such as silicone resin is used as the thermoplastic resin, the peeling substance bleeds out and the peeling degree becomes unstable depending on the temperature and humidity. It is easy to get into a state. Further, a region where the peeling force is partially reduced is generated on the peeling surface, and in some cases, the film does not peel off. Further, the bleed-out peelable substance often migrates to the adhesive surface, and it is difficult to maintain the daily peeling stability in any environment. The above packaging has the same problems as above, and since a film in which a peelable area and a sealable area are set in advance is used, a heat seal layer is provided and the product is always packaged at a fixed position. Must be done, and it is inferior in economic efficiency and productivity. In the package of 1) above, release paper is still required for the adhesive layer of the absorbent main body, and in the packaging structure of 2) above, release paper is required for the adhesive layer of the flap portion. It is necessary, and neither of them has solved the above-mentioned problem caused by the release paper. Further, in the packaging body of the above 3), since the adhesive layers of both the flap and the absorbent main body are covered with the double-sided release paper, the above-mentioned problems caused by the release paper have not been solved. In the packaging structures of 1) and 2) above, since the packaging material is opened and one end of the packaging material is peeled off so as to be flipped over, the napkin cannot be immediately taken out from the packaging material. (3 above)
Similarly, in the packaging structure described above, after the exposed release paper is pulled from the opening of the packaging material to open it, the napkin and the release paper are peeled off, so that the napkin cannot be immediately taken out. In the packaging structure of the above 4), since the napkin is pulled out from the front end or the rear end of the napkin and the napkin is in the expanded form, it cannot be immediately taken out from the packaging material while the napkin is folded. That is, the above-mentioned structure of the packaging body, the adhesive layer provided on the sanitary napkin and the peeling property between the peeling layer provided on the packaging body, and the tack force against the shorts of the adhesive layer are sufficient for practical use. There is a problem that we cannot satisfy with sex.

Therefore, it is an object of the present invention that the release paper does not have to be discarded, and the sanitary napkin is provided with an adhesive layer having a sufficient tack force against shorts when used, and the packaging of the adhesive layer. It is an object of the present invention to provide a packaging structure for a sanitary napkin which is also excellent in peelability from a material.

[0006]

As a result of intensive studies to solve the above problems, the present inventors achieved the above object by fixing one end of a release paper at a specific position in a packaging structure. They found that they could obtain the present invention and completed the present invention.

That is, the present invention comprises a sanitary napkin and a packaging material for packaging the sanitary napkin, the adhesive layer being provided on the non-skin-contacting surface of the sanitary napkin, and being fixed to the inner surface of the packaging material. In a packaging structure of a sanitary napkin, which is detachably adhered with a release paper, the sanitary napkin is folded in the longitudinal direction to form a bent portion, and the sanitary napkin is formed in the longitudinal direction. Of the sanitary napkin formed by opening the packaging material is provided along the side edge or the bent portion, and at least one end of the release paper is The present invention provides a sanitary napkin packaging structure characterized by being fixed to the inner surface of the packaging material in the vicinity thereof.

[0008]

In the packaging structure of the present invention, the sanitary napkin folded in the longitudinal direction is packaged by the packaging material, and the adhesive layer of the sanitary napkin is detachably attached to the release paper fixed to the packaging material. It is sticky. Before the sanitary napkin is used (at the time of storage), the adhesive layer provided on the sanitary napkin is entirely protected by a release paper fixed to the packaging material. Further, when the sanitary napkin is used, the packaging material is opened, and the sanitary napkin is taken out from the taking-out port of the sanitary napkin thus formed, whereby the adhesive layer and the release paper are peeled off, The sanitary napkin with the adhesive layer exposed can be attached to shorts.
