[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary napkin packaging structure which does not have a release paper for protecting an adhesive portion for fixing to a short, and has a sufficient tack force to the short.

[0002]

2. Description of the Related Art Generally, sanitary napkins are fixed to shorts,
In addition, an adhesive for preventing displacement during use and a release paper for protecting the adhesive are provided. In such a sanitary napkin, it is necessary to peel and discard the release paper when using the sanitary napkin. Therefore, there is a problem in that the disposal of the release paper is troublesome, and when the paper is discarded in the toilet, the toilet is clogged.

Therefore, various techniques relating to a sanitary napkin packaging structure having no release paper have been proposed, and specific examples thereof include the following. A sanitary napkin package in which an adhesive layer of a sanitary napkin is directly in contact with a polyolefin-based film (Japanese Utility Model Publication No. 59-9615).
A package made of a water-soluble film and individually packaged with a sanitary napkin, using a packaging material having a release layer at a portion in contact with the adhesive layer of the sanitary napkin (Japanese Utility Model Application Laid-Open No. 59-253).
No. 71). The adhesive layer of the sanitary napkin is exposed from the opening end of the pocket portion of the packaging material, and the non-adhesive layer of the packaging material is fixed on the upper surface of the pocket portion by fastening the adhesive layer. No. 34211). An individual sanitary napkin wrapping material (actually opened) is provided with a wrapping material having a peeling treatment portion at a portion in contact with the adhesive portion of the sanitary napkin, sealing four sides of two sheets and providing perforations for opening. 1958
-179120). A sanitary napkin package (Japanese Utility Model Application Laid-Open No. 63-63) in which a multi-layer resin film having a release layer in a portion in contact with the pressure-sensitive adhesive layer of the sanitary napkin is used as a packaging material.
No. 71025). A napkin packaging material comprising a film made of a resin mainly composed of an olefin polymer and a silicone copolymer (Japanese Utility Model Laid-Open No. 2-35724).
Napkin wrapping material with a silicone-coated release area and a heat-sealable sealing area.
No. 11324). 1) A package of a napkin with a wing using a flap as a protective member for covering and protecting the adhesive of a sanitary napkin (Japanese Utility Model Laid-Open No. 3-46316). 2) A packaging structure of a napkin with a wing, in which a release paper is provided to protect an adhesive layer at a flap portion.
(Japanese Utility Model Laid-Open No. 2-17127) 3) In a napkin with a wing, using a double-sided release paper,
A sanitary napkin package coated with a flap and an adhesive layer of an absorbent main body (Japanese Utility Model Laid-Open No. 63-186645). A packaging structure in which a featherless sanitary napkin is packaged with a packaging material subjected to a peeling treatment (Japanese Patent Application Laid-Open No. 3-176376).

[0004] However, in the above-mentioned package,
There are the following problems. In the above-mentioned package, since the packaging material for packaging the napkin is a single film, the releasability decreases with time, and the packaging material stretches or tears when the napkin is taken out. Further, if the film thickness is increased to suppress this, not only the cost is increased but also the film itself becomes hard and the package cannot be easily opened. In the above-mentioned package, there is a problem that the film strength is low, and the package is stretched or peeled when peeling the packaging material, and when the degree of peeling of the film is increased to solve such a problem, Water solubility is impaired and clogs the toilet bowl when discarded. In the above-mentioned package, since the adhesive layer can be provided only on a part of the napkin, the napkin has poor fixability when used. In the above-mentioned package, a perforation is provided. However, since air easily enters from the perforation and the package swells, it is difficult to carry or open the package. In the above-mentioned package, since the material or copolymer containing a peelable substance such as a silicone resin is used as the thermoplastic resin, the peeled substance bleeds out and the peeling degree is unstable due to temperature or humidity. It is easy to be in a state. Further, a region where the peeling force is partially reduced occurs on the peeling surface, and in some cases, the film does not peel off. In addition, the bleed-out release material often migrates to the adhesive surface, and it is difficult to maintain daily release stability in any environment. In the above-mentioned package, there is a problem similar to the above,
Furthermore, since a film in which a peelable area and a sealable area are set in advance is used, it is necessary to provide a heat seal layer and always package the product at a fixed position, which is inferior in economy and productivity. In the package of the above 1), a release paper is still required for the adhesive layer of the absorbent main body, and in the packaging structure of the above 2),
For the adhesive layer of the flap part, release paper is required,
In both cases, the problem with the release paper described above has not been solved. Further, in the package 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 problem with the release paper has not been solved. In the above-mentioned packaging structure, no technique relating to a napkin with a wing has been proposed, and the problem of providing the above-described release paper in a napkin with a wing has not been solved.

[0005] That is, the structure of the above-mentioned package has the following characteristics: the releasability between the adhesive layer provided on the feathered sanitary napkin and the release layer provided on the package, and the tack force of the adhesive layer against shorts. There is a problem that both cannot be satisfied with sufficient practicality.

Accordingly, it is an object of the present invention to provide a sanitary napkin with a wing having a wide range of adhesive layer so as to have a sufficient tack force to shorts when used, and to peel the adhesive layer from a packaging material. It is an object of the present invention to provide a sanitary napkin packaging structure having excellent properties.

[0007]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies in order to solve the above-mentioned problems. As a result, the sanitary napkin having a flap is temporarily wrapped with a packaging material, and the temporarily wrapped sanitary napkin is used. The above object has been achieved by a packaging structure folded integrally with a packaging material.

Accordingly, the present invention includes a napkin main body, the left and right side edge portions in the longitudinal direction, the upper Symbol sanitary napkins that have a pair of flaps formed by extending the width of each of outward , temporarily packaged with packaging materials, the temporary packaged the sanitary napkin and folded integrally with the wrapping material in the bent portion, formed by fastening the side edge portions of the packaging material, for physiological In the packaging structure of the napkin, a main body adhesive layer is provided on a non-skin contact surface of the napkin main body, and a peeling portion is provided on a corresponding portion of the main body adhesive layer on an inner surface of the wrapping material, The pair of flaps has a non-skin contact surface

[0010]

According to the present invention, the sanitary napkin having a flap is temporarily wrapped with a wrapping material, and the temporarily wrapped sanitary napkin is integrally folded with the wrapping material and individually wrapped. Before use (during storage), at least the adhesive part provided on the napkin body is entirely protected by the peeling part provided on the packaging material. Even if the adhesive portion is provided in a wide range, the adhesive portion can be protected without using release paper. Further, when the sanitary napkin is used, the adhesive portion of the napkin body can be exposed and attached to the shorts simply by peeling off the packaging material. Further, when the adhesive portion is formed of an adhesive that separates between layers, the adhesive portion can be protected without providing a peeling portion on the packaging material.

Further, even when the adhesive of the adhesive portion 56A and the adhesive of the adhesive portion 56B are the same, a release sheet whose surface to the adhesive portion 56A has been subjected to a release treatment is disposed between the adhesive portions. An adhesive portion that peels between layers can be formed. The peeling force between the adhesive section 56A and the release sheet is 10
~ 200 g / 50 mm, preferably 30-90 g / 50
The range of mm is more desirable. The measurement of the peeling force was determined by the same method as the measurement of the adhesive force described above.
