Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is in the field of sanitary napkins, and more particularly relates to improvements in individual packages thereof.

In between the conventional blue and recent sanitary napkins, the surface of the sanitary napkin is coated with an adhesive so that it can be fixed to clothing during use, and it is also coated with an appropriate film for portability and hygiene reasons.
Many of the sanitary napkins in the J Kamoriko style are individually packaged, and the adhesive coated on the surface is covered with release paper. This prevents the agent from adhering to the film forming the package. Therefore, when using the sanitary napkin, it is troublesome to open the package, take out the sanitary napkin, and remove the release paper from the napkin, and there is also the problem that the release paper must be disposed of in an appropriate place. there were.

SUMMARY OF THE INVENTION An object of the present invention is to provide an individually packaged sanitary napkin that solves these problems in conventional individually packaged sanitary napkins.

INDUSTRIAL APPLICABILITY The present invention employs a specific multilayer structure as a material for individual packages of sanitary napkins whose surfaces are coated with an adhesive. The above-mentioned problems are solved.That is, the individual package of the present invention consists of a release agent layer and a material that is present on the release agent layer and has a melting point higher than the melting point of the release agent. It has a multilayer structure including a film and a film made of a high melting point material and a material having a melting point lower than the release agent on the high melting point film, and the low melting point film is heat welded and sealed. It is characterized by forming a bag.

In the individual sanitary napkin sanitary napkin individual packaging of the present invention having such a structure, the individual packaging itself is equipped with a release agent, so unlike conventional packaging, it is not necessary to apply release paper to the sanitary napkin with adhesive. It is no longer necessary to place it in the section. Therefore, when using sanitary napkins,
It is only necessary to open the individual packages, and there are no problems associated with discarding the release paper. Further, the individual sanitary napkin packaging of the present invention has a special multilayer structure, so that it can be easily manufactured to have a reliably sealed shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to further clarify the characteristics of the individual packaged sanitary napkin of the present invention, the present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 is a partially cutaway view of the individual package of sanitary napkins according to the present invention shown generally in FIG. 2. In the figure, an individual package designated by reference number 1 houses a sanitary napkin 2 therein. The surface of the sanitary napkin 2 is coated with an adhesive 3 for fixing it to clothing (see FIG. 2). The individual package consists of a lowermost release agent layer 4, a film 5 on top of which is made of a material having a higher melting point than the release agent. It has a multi-layer structure including a film 6 made of a material having a melting point lower than that of the high melting point material and the release agent, which exists on the high melting point film 5. Thus, in the package 1, the low melting point film is thermally welded at 7 to form a sealed bag. A suitable combination of materials forming the multilayer structure includes a silicone resin (generally having a melting point of 140 to 160°C) as a release agent for forming the release agent layer 4 and a high melting point film 5.
Polyproblene or ionomer resin (melting point is about 180°C, for example), low melting point film 4
Polyethylene (melting point is about 1
20°C).

The individual packaged sanitary napkin of the present invention as shown in the figure is manufactured as follows. First, high melting point film 5
A release agent, for example, a silicone resin, is heated above its melting point on the high melting point film side of the multilayer film consisting of the and low melting point film 6, so that the adhesive of the sanitary napkin exists along the X direction in FIG. Apply to the corresponding areas individually. Next, both edges of the multilayer film coated with the release agent in the horizontal direction (X direction in Figure 2) are heat-sealed, and the edges in the vertical direction (Y direction in Figure 2) are sealed. Form a film structure with open ends. Therefore, a sanitary napkin is inserted into such a film structure, and the sanitary napkin is placed in the vertical direction (Y in Fig. 2).
While heating the low melting point film 6 along the edge of the direction (direction) to a temperature at which the low melting point film 6 melts (however, the release agent layer 4 and the high melting point film 5 do not melt), the low melting point film 6 is heated in the direction of the arrow in FIG. When stretched in the direction, the remaining portion of the film is cut while the film 6 joins each other at the joint 7. By such heat welding operation, a completely sealed individual sanitary napkin package can be obtained. At this time, the individual wrapping device body is in contact with the adhesive application part 3 of the internal sanitary napkin via the lowest fJI'A% agent layer 4, so there is no need to provide a release paper. Also, the sanitary napkin with the adhesive application part 3 exposed can be directly taken out by simply opening the individual package at the time of use.
