It is only necessary to peel off the bonded protruding areas from each other, and there is no need for a conventional bag.

  That is, it is possible to provide a bodily fluid-absorbing contact material that can reduce the redundant labor of opening and removing the bag body.

  The configuration of the present invention will be described below with reference to the drawings showing the embodiments.

  As shown in FIGS. 1 to 4, the bodily fluid absorbing contact material of this embodiment includes a contact material body 1 and a peeling member 2 having regions to absorb bodily fluids such as sweat, menstrual blood, vaginal discharge, and incontinence urine. It comprises. And the adhesive is apply | coated to the back surface of the base material main body 1 in order to form the adhesion part for affixing on underwear. As the pressure-sensitive adhesive, a known hot-melt type was used in this example. As the adhesive part, a double-sided tape or the like can be used in addition to the adhesive.

  The contact material body 1 is formed of a synthetic resin nonwoven fabric. In addition, you may form by the thing made from a product made from a chemical fiber or a natural fiber, or these. Moreover, the base material body 1 is formed in a track shape of substantially athletics. In addition, an appropriate shape such as a violin shape or an oval shape can be employed.

  As shown in FIG. 2, the release member 2 is formed by laminating a nonwoven fabric layer 20 and a polyethylene film as a thermoplastic resin layer 21 by multi-layer adhesion (so-called laminating treatment), and the polyethylene film 21 has a release agent. A release layer 22 is formed by applying a silicone resin. The silicon resin is heated and applied to the polyethylene film 21, and then dried. Since the non-woven fabric layer 20 is laminated on the polyethylene film 21, the film does not crush due to the action of heat during drying. Moreover, the width of the peeling member 2 is formed wider than the width in the left-right direction of the contact material body 1.

  As the nonwoven fabric layer 20, a wet nonwoven fabric of rayon fiber is used. As the nonwoven fabric layer 20, either one formed by a wet method or one formed by a dry method can be selected. Further, as the aspect of the nonwoven fabric layer 20, one formed by papermaking such as paper can be selected. That is, in this specification, the nonwoven fabric includes paper.

  As the thermoplastic resin layer 21, in addition to the polyethylene film, materials such as ethylene vinyl acetate copolymer (EVA), nylon, polypropylene, vinyl chloride, polybutylene terephthalate (PBT) can be used. The polyethylene film has advantages in that it is excellent in processability because it is excellent in cost and has a relatively low softening temperature.

  As the release agent, acrylic resin, melamine resin, fluorine resin, or the like can be used in addition to the silicon resin. Silicone resin has the advantage of being excellent in cost and releasability.

  Unevenness was formed on the peeling member 2 by a known embossing process. Irregularities can be formed by corona discharge treatment, chemical treatment, etc. in addition to embossing treatment. The peeling member 2 on which the unevenness is formed has an advantage that the texture is good. Concavities and convexities may or may not be formed.

  A bodily fluid absorbing batting material was formed by the batting material body 1 and the peeling member 2 as follows. A hot-melt pressure-sensitive adhesive layer is formed between the surface (surface 3) on the polyethylene film 21 side of the peeling member 2 and the backing material body 1, and both are adhered. In this way, an adhesive part is formed in the base material body 1. In this attached state, the contact material body 1 is folded as the inner side. As shown in FIGS. 3 to 5, in this embodiment, regions of about one third of the entire length are alternately folded from both ends. And as shown in FIG. 4, between the peripheral area | regions 23 of the said peeling member 2 which protruded in the left-right direction of the contact material main body 1 is thermocompression-bonded (The state which thermocompression-bonded only one side is illustrated for description). In this example, a commercially available heat sealing machine was used and thermocompression bonded at about 180 ° C.

  Examples of the thermocompression bonding include the surfaces 3 of the peeling member 2 and between the surface 3 and the back surface 4 of the peeling member 2. A silicon resin is applied to the surface 3 of the peeling member 2 on a polyethylene film 21 that is fixed to the nonwoven fabric layer 20 and is laminated. However, since the polyethylene film 21 is interposed, thermocompression bonding between these surfaces is possible. The nonwoven fabric layer 20 on the front surface 3 and the back surface 4 of the peeling member 2 can be thermocompression bonded because the polyethylene film 21 on the front surface 3 is interposed.

  Since the polyethylene film 21 forming the peeling member 2 is coated with a silicone resin, the peeling member 2 has a peelability from the adhesive portion formed on the base material body 1 like the conventional release paper 5. Have.
