Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary napkin packaging structure which does not require disposal of release paper and has sufficient tack force for shorts.

[0002]

2. Description of the Related Art A sanitary napkin usually has a napkin fixed to shorts.
Moreover, an adhesive for preventing misalignment during use and a release paper for protecting it are provided, and in such a sanitary napkin, it is necessary to remove and discard the release paper when using it. Therefore, it is difficult to dispose of the release paper, and when it is discarded in the toilet bowl, the toilet bowl becomes clogged.

Therefore, various techniques relating to the packaging structure of a sanitary napkin without a release paper have been proposed, and specifically, there are the following. A sanitary napkin package in which the adhesive layer of the sanitary napkin is directly contacted with the polyolefin film (Japanese Utility Model Publication No. 59-9615). A package made of a water-soluble film, in which a sanitary napkin is individually packaged in a packaging bag having a release layer at a portion in contact with the adhesive layer of the sanitary napkin (Actual No. Sho 59-253).

1) A napkin-wrapped body with blades in which the flap is used as a protective member for covering and protecting the pressure-sensitive adhesive of a sanitary napkin (Japanese Utility Model Publication No. 3-46316). 2) A packaging structure of a napkin with wings, in which a release paper is provided to protect the adhesive layer of the flap portion (Japanese Utility Model Laid-Open No. 2-17127). 3) In a napkin with wings, using double-sided release paper,
A package of a sanitary napkin covered with a flap and an adhesive layer of an absorbent main body (Japanese Utility Model Publication No. 63-186645).

1) A napkin packaging structure in which a sanitary napkin is packaged in a packaging bag that has been subjected to a peeling treatment (Japanese Patent Laid-Open No. 3-17637).
No. 6). 2) A packaging structure in which the release paper and the packaging bag are fixed so that the release paper can be peeled off at the same time when the napkin is taken out of the bag (Japanese Utility Model Laid-Open No. 1-1509919). 3) A napkin packaging structure in which release paper is sandwiched at the mouth of a packaging bag and the release paper is peeled off from the adhesive portion at the same time when the bag is opened (Japanese Utility Model Publication No. 60-79421). 4) A packaging structure in which the release paper can be automatically peeled off by opening the packaging bag and taking out the sanitary napkin (Japanese Utility Model Laid-Open No. 58-58029 and Japanese Utility Model Laid-Open No. 4-120).
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 4) above, since the napkin is pulled out from the front end or the rear end of the napkin and the napkin is in a developed form,
I cannot take out the napkin from the packaging bag immediately with it folded. That is, the structure of the above-mentioned package, the adhesive layer provided on the sanitary napkin and the peeling property between the release layer provided on the package, and the tack force against shorts of the adhesive layer are both practical. There is a problem that we cannot satisfy with sex.

Further, a release paper is fixed on the inner surface of the packaging bag,
A packaging structure in which the fixed release paper and the adhesive layer of the sanitary napkin are adhered has also been proposed. However, in such a packaging structure, when the packaging bag is opened and the sanitary napkin is taken out, the above-mentioned peeling is performed. There is a problem that the 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 at the time of use, 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.

[0013]

The present invention comprises a sanitary napkin and a packaging bag in which the sanitary napkin is individually packaged, and an adhesive layer provided on the non-skin-contacting surface of the sanitary napkin and the packaging bag. In a packaging structure for a sanitary napkin, which comprises a release paper fixed to an inner surface and releasably adhered to the sanitary napkin, the sanitary napkin has two folds which divide its longitudinal direction into a front portion, a central portion and a rear portion. Part, the central part is folded in three on the skin contact surface side, and the adhesive layer is provided on at least the front part and the central part, and the packaging bag forms an outlet for the sanitary napkin. The opening section is provided along one side edge in the longitudinal direction of the sanitary napkin, and the release paper consists of one sheet and covers all the adhesive layers. Adhesive, near the one edge of the release paper in the longitudinal direction The packaging structure for a sanitary napkin, wherein the sanitary napkin is fixed to the inner surface of the packaging bag only by itself, and is peeled off from the adhesive layer when the sanitary napkin is taken out from the outlet. The above object is achieved by providing the following.

[0014]

In the packaging structure of the present invention, the sanitary napkin is individually packaged in the packaging bag, and the adhesive layer of the sanitary napkin is
It is removably adhered to the release paper of the packaging bag. Before the sanitary napkin is used (at the time of storage), the adhesive layer provided on the sanitary napkin is entirely protected by a piece of release paper fixed to the packaging bag. Also,
When the sanitary napkin is used, the packaging bag is opened, and the sanitary napkin is pulled out from the sanitary napkin taking-out port thus formed, whereby the release paper is gradually peeled from the adhesive layer and fixed. Since the unfilled portion follows the adhesive layer and jumps out of the packaging bag, the adhesive layer can be smoothly peeled off, the sanitary napkin can be taken out, and the sanitary napkin can be attached to shorts or the like for use.
