Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sanitary product, namely a sanitary napkin or a disposable diaper.

Generally, sanitary napkins that have been commercially available in recent years are
Each piece is appropriately folded and sealed into a bag with packaging material. When using a napkin, the wrapping material is torn, the napkin is taken out, and the wrapping material is thrown away. That is, the packaging material simply has the function of packaging the napkin for hygiene and appearance reasons, and is uneconomical because it cannot be reused after the napkin is taken out.

On the other hand, even if commercially available napkins are washable, they can clog the drain pipe if they are dumped into a flush toilet bowl, so be sure to prepare them in the toilet after use. It is being dumped in a waste container. However, even if it is dumped into the container, if the menstrual blood remains attached, the container will be soiled with menstrual blood and the person cleaning it will feel uncomfortable. For this reason, used napkins are sometimes wrapped in paper strips such as tissue paper and thrown into the container, but since they are then dumped in another location with general garbage, it is difficult to handle them properly. When the napkin is thrown away, the paper strip may open and the napkin with menstrual blood adhered to it may be exposed, causing discomfort to cleaners and the like, as described above.

Therefore, in order to store used napkins in a bag and dispose of them, an idea has been proposed in which a bag of approximately the same size is integrally attached to the napkin.
This is not only uneconomical as it requires the use of a separate packaging material to seal the napkin, but also is not practical since it is difficult to wear the napkin. In addition, in foreign countries, separate small bags for storing and disposing of used napkins are stored in a large exterior bag for the number of napkins, but these small bags are used separately from the packaging material for each napkin. It is uneconomical because it is

On the other hand, disposable diapers that have been on the market in recent years are not individually packaged using packaging materials.
For this reason, used diapers are wrapped in comparatively large sheets of paper, plastic sheets, or bags made of these materials and then thrown away.Especially when traveling, it is important to carry the above-mentioned paper for disposal separately from the diapers. There are some hassles you have to go through.

In view of the above-mentioned drawbacks, the purpose of the present invention is to provide an individual packaging structure for sanitary products that has both the functions of individual packaging and a sachet for disposal after use, and a preferred embodiment thereof will be explained below. Then, the result is as follows.

The present invention consists of a sanitary product 1 and a packaging bag 2 for the sanitary product.

The sanitary product 1 is appropriately folded so that the skin-contacting side is on the inside to make the shape smaller, and then hermetically sealed in a packaging bag 2.

The packaging bag 2 is made of a sheet 3 made of plastic film, a laminated paper of the film, waterproof paper, or other paper, and one end of the rectangular sheet 3 is folded inward in the vertical direction, and both sides of the rectangular sheet 3 are folded inward in the horizontal direction. By gluing the edges 5a and 5b together,
A pocket portion 6 having an appropriate depth and having an open upper end and a lid portion 7 extending from the back surface thereof are formed. The sheet portions 4' on the front and back surfaces forming the opening periphery of the pocket portion 4 are made such that a portion of the sheet 3 is made thicker to be more rigid than other portions, as shown in FIG. In order to do this, as shown in FIG.
Alternatively, as shown in FIG. 6, a part of the sheet 3 is folded back on one side of the opening periphery 4', and a core piece 11 is placed inside the sheet 3.
may be interposed, and the means for forming it rigidly is not limited. The folded sanitary product 1 is stored in the pocket part 6, and an adhesive part 8 coated with a solvent-based adhesive, a hot-melt adhesive, etc. is provided on the surface of the pocket part 6, and the lid part 7 is attached to the pocket part 6 through the adhesive part. is removably adhered to the surface of the pocket portion 6. The length of the adhesive part 8 does not necessarily correspond to the length of the pocket part 6 as shown in the figure.
It does not have to span the entire width of the area. Furthermore, the inner surfaces of both lateral edges 9 of the lid portion 5 are releasably adhered to the surfaces of the lateral edges 5a of the pocket portion 6, and the adhesive force of this portion is sufficient to form the pocket portion 6. The adhesive force is made weaker than that of the lateral side edges 5a, 5b. This is because when opening the lid part 7 to take out the napkin 1 in use, that is, when opening the lid part 7 to take out the napkin 1, the lateral sides 9 of the lid part 7 are pressed against the lateral sides 5a of the pocket part 6.
This is to prevent the adhesion between the lateral side edges 5a and 5b from peeling off due to the tensile force when the adhesive is peeled off. By the way, pocket part 6
Needless to say, the adhesion force of the adhesive portion 6 to the surface is also weaker than the adhesion force of the lateral side edges 5a, 5b.

In this way, the lateral side edges 5a of the pocket portion 6,
In order to make the adhesion force of the lateral side edges 9 of the lid part 7 to the lateral side edges 5a weaker than the adhesive force of the lid part 5b, for example, the following method can be adopted.
That is, when the material of the packaging bag 2 has heat-sealability, and is particularly a polyolefin film, both lateral edges 5a and 5b of the pocket portion 6 are heat-sealed, and both lateral edges 5a and 5b of the lid portion 7 are heat-sealed. 9 is subjected to a so-called corona discharge treatment. In this treatment, ozone and nitrogen oxide that have created a corona react with the area to generate carbonyl groups and make it hydrophilic, and it is known that if the treatment is excessive, the heat sealability will deteriorate. In this embodiment, in order to take advantage of this characteristic, the above-mentioned portion is excessively treated and heat-sealed in a state where the heat-sealability is reduced. Further, when the material sheet 3 of the packaging bag 2 has heat-sealing properties, the lateral side edges 5a, 5 of the pocket portion 6
In addition to heat-sealing b, printing ink or resin is applied to the inner surface of both lateral edges 9 of the lid part 7 so that the area becomes uneven or is guided in a linear manner to improve the heat-sealability of the area. Heat seal in the lowered state.

Furthermore, when the material sheet 3 of the packaging bag 2 does not have heat-sealing properties, it is integrally adhered to the opposing inner surfaces of both lateral edges 5a and 5b of the pocket portion 6 with a strong adhesive, and the lid is sealed. The inner surfaces of both side edges 9 in the lateral direction of the portion 7 may be releasably adhered to the surfaces of both side edges 5a in the lateral direction of the pocket portion 6 using an adhesive with low adhesive strength.

In addition, a sheet having heat-sealability is used as the material sheet 3 of the packaging bag 2, and the pocket portion 4 is
When heat-sealing the inner surfaces of both lateral edges 5a and 5b of the lid part 7 to the surfaces of the lateral edges 5a and 5b, the heat sealing can be performed simultaneously. As described above, the inner surfaces of both side edges 9 in the lateral direction of the lid portion 7 may be treated in advance to reduce the heat sealability.

According to the present invention having the above-mentioned configuration, when in use, the lid part 7 of the packaging bag 2 is inserted into the pocket part 6.
Remove the sanitary product by peeling it off from the surface of the sanitary product, fold the dirty sanitary product 1 after use to its original state, store it in the pocket part 6 again, and attach the lid part 7 to the surface of the pocket part 6 using the adhesive part 8. It is to be attached to. Therefore, all of the conventional drawbacks mentioned above can be solved, and the used napkin 1 packaged in the packaging bag 2 will not be exposed from the packaging bag 2 during subsequent handling. do not have. Moreover, when the lid part 5 is peeled off, the bonded state of both lateral ends 3a and 3b of the pocket part 4, which are bonded to form the pocket part 4, is not damaged, and the packaging bag 2 can be reused. can fully perform its functions. Furthermore, the opening periphery 4' of the pocket section 6 is formed to be rigid and strong, so if you grasp both lateral edges of the pocket section 6 with your fingertips and press it toward the center, the opening will open. It can be easily expanded, so that the sanitary product 1 can be easily stored in the pocket part 6 after use. It has the following effects and is extremely useful for practical use as a product of this type.
