DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 to 4,
The bodily fluid-absorbing pad material of this embodiment comprises a pad material body 1 having a region for absorbing body fluid such as sweat, menstrual blood, swelling, or incontinence, and a peeling member 2. Then, an adhesive is applied to the back surface of the patch material body 1 so as to form an adhesive portion to be attached to the underwear. In this embodiment, a known hot melt type adhesive was used as the adhesive. As the adhesive part, a double-sided tape or the like can be used in addition to the adhesive.

The pad main body 1 is made of a synthetic resin non-woven fabric for absorbing body fluid. In addition, it may be formed of chemical fibers or natural fibers, or a mixture thereof. Further, the patch material body 1 is formed into a track shape for substantially athletics. Besides, an appropriate shape such as a violin shape or an oval shape can be adopted. As shown in FIG. 2, the peeling member 2 is formed by stacking paper 20 and a polyethylene film, which is a heat-fusible resin 21, on multiple layers (so-called laminating process), and the polyethylene film 21 is a silicone resin, which is a peeling agent 22. Is being applied. The silicone resin 22 is heated and applied to the polyethylene film 21, and then dried. Since the paper 20 is laminated on the polyethylene film 21, the film does not become crunchy due to the action of heat during drying. Further, the width of the peeling member 2 is formed wider than the width of the patch material body 1 in the left-right direction.

As the heat-fusible resin, in addition to the polyethylene film, ethylene vinyl acetate copolymer (EVA),
Nylon, polypropylene, vinyl chloride, polybutylene terephthalate (PBT), etc. can be used. The polyethylene film has an advantage that it is excellent in processability because it is excellent in cost and has a relatively low softening temperature. In addition to the silicone resin, an acrylic resin, a melamine resin, a fluororesin, or the like can be used as the release agent. Silicone resin has the advantages of excellent cost and peeling properties.

Concavities and convexities are formed on the peeling member 2 by a known embossing treatment. The irregularities can be formed by corona discharge treatment, chemical treatment, etc. in addition to the embossing treatment. The peeling member 2 having the unevenness has an advantage that it has a good texture. The unevenness may or may not be formed. This body fluid absorbing pad can be formed as follows. A hot-melt type pressure-sensitive adhesive layer is formed between the surface of the peeling member 2 on the polyethylene film 21 side (front surface 3) and the patch main body 1, and both are adhered. In this way, an adhesive portion is formed on the patch material body 1. In this attached state, the patch material body 1 is folded with the main body 1 facing inward. As shown in FIGS. 3 to 5, in this embodiment, approximately one-third of the entire length is alternately folded from both ends. And
As shown in FIG. 4, the peripheral regions 23 of the peeling member 2 protruding in the left-right direction of the patch member body 1 are thermocompression-bonded to each other (only one side is thermocompression-bonded for illustration).
In this example, a commercially available heat sealing machine was used and thermocompression bonding was performed at about 180 ° C.

As a mode of thermocompression bonding, the surface 3 of the peeling member 2 is used.
And the front surface 3 of the peeling member 2 and the back surface 4 of the peeling member 2. On the surface 3 of the peeling member 2, a silicone resin 22 is applied to a polyethylene film 21 which is fixed to the paper 20 in multiple layers, but since the polyethylene film 21 is interposed, thermocompression bonding between these surfaces is possible. Since the polyethylene film 21 on the front surface 3 is interposed between the front surface 3 and the paper 20 on the rear surface 4 of the peeling member 2, thermocompression bonding is possible. Since the polyethylene film 21 forming the peeling member 2 is coated with the silicone resin 22, the peeling member 2 can be peeled off from the adhesive portion formed on the patch material body 1 like the conventional peeling paper 5. have.

In this embodiment, since the bodily fluid absorbing pad is constructed as described above, the peeling member 2 is made to have the function of the conventional bag body, and when used, the folded pad is expanded to form the peeling member 2. There is an advantage that it is possible to reduce the duplicated labor by only removing the labor. Further, since the polyethylene film 21 side surface (surface 3) of the peeling member 2 is stuck to the adhesive portion formed on the patch material body 1, since the patch material body 1 is folded inside, As in the conventional case where the bags 7 are individually housed one by one, dust can be prevented from entering the patch material body 1, which is hygienic. Further, in the conventional case, both the bag body 7 and the release paper 5 (see FIGS. 5 and 6) are generated as dust that should be discarded when applied to the underwear. There is an advantage that it is possible to reduce the number of dusts and the troublesomeness of throwing away the dust only with the member 2.

In the above-mentioned embodiment, the paper 20 and the polyethylene film 21 are laminated one layer at a time to form a total of two layers, but the surface of the peeling member 2 on the side of the paper 20 where the paper 20 and the polyethylene film 21 are laminated together is laminated. Alternatively, the polyethylene film 21 may be fixed in multiple layers to form a three-layer structure (not shown). Also in this case, as in the case of the above embodiment, the polyethylene film 21
Of the peeling member 2 between the surfaces 3 and the peeling member 2
It is possible to perform thermocompression bonding between the front surface 3 and the back surface 4 of the. Further, when formed in this way, both sides of the peeling member 2 are covered with the polyethylene film 21, and there is an advantage that the appearance is more excellent because it has gloss.

[0017]

The present invention has the above-mentioned structure and has the following effects. Since the heat-bonding resin 21 enables thermocompression bonding between the surfaces of the peeling member 2 and between the front surface and the back surface of the peeling member 2, the peeling member 2 also has a function as a bag. It is possible to provide a bodily fluid absorption padding material that can reduce duplication of time during use.
