733 publication).

However, in the above package,
There are the following problems. In the above-mentioned package, since the packaging bag for packaging the napkin is a single film, the peeling property decreases with time, and the packaging bag stretches or tears 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 package, the film strength is low, there is a problem of stretching or tearing when peeling the packaging bag, also, if the peeling degree of the film is increased to solve such a problem, the film 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 of the napkin during use is poor. 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 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.

In the above package,
There is a problem similar to the above, and since a film with a peelable area and a sealable area is set in advance,
Since it is necessary to provide a heat seal layer and always wrap the product at a fixed position, 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 structure of 1) and 2) above,
Since the packaging bag is opened and one end of the packaging bag is peeled off and peeled off, the napkin cannot be immediately taken out from the packaging bag. Similarly, in the packaging structure of 3) above, after the exposed release paper is pulled from the opening of the packaging bag to open it, the napkin and the release paper are separated, 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 has a developed form, it cannot be immediately taken out from the packaging bag with the napkin folded.

That is, the above-mentioned structure of the package has both the peelability between the adhesive layer provided on the 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 it cannot be satisfied with sufficient practicality.

A packaging structure has also been proposed in which a part of the release paper is fixed to the inner surface of the packaging bag and the fixed release paper and the adhesive layer of the sanitary napkin are adhered to each other. In the packaging structure, when the packaging bag is opened and the sanitary napkin is taken out, the release paper is also grabbed together, and the sanitary napkin cannot be taken out smoothly.

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

[0014]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventors achieved the above object by providing a specific opening portion in a packaging bag constituting 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 bag in which the sanitary napkin is individually packaged. The adhesive layer is provided on the non-skin contact surface of the sanitary napkin and is fixed to the inner surface of the packaging bag. In the packaging structure of a sanitary napkin made by detachably adhering the release paper, the sanitary napkin is folded in its longitudinal direction, and the packaging bag has one main opening part and two An opening part including a sub-opening part is provided, and the opening of the sanitary napkin is formed by opening the opening part. The main opening part is one side edge of the packaging bag. The length of the main opening portion is longer than the length of one side edge of the folded sanitary napkin and more than the length of the one side edge of the packaging bag. The sub-opening part is provided so as to be short. The physiology is characterized in that it is linearly provided from both ends of the main opening part in a direction orthogonal to the main opening part, and the opening part is formed in an I shape or a U shape. The present invention provides a packaging structure for a napkin for use (hereinafter, this invention will be referred to as the "first invention").

Further, the present invention comprises a sanitary napkin and a packaging bag in which the sanitary napkin is individually packaged, and the adhesive layer is provided on the non-skin contact surface of the sanitary napkin and is fixed to the inner surface of the packaging bag. In a packaging structure for a sanitary napkin, which is obtained by releasably adhering the released paper, the sanitary napkin is folded in its longitudinal direction, and the packaging bag has an opening part, and the opening part The opening of the sanitary napkin is formed by opening the
The unsealing portion is provided in a curved shape along one side edge of the packaging bag, and the length of the unsealing portion is longer than the length of one side edge of the folded sanitary napkin.
