Problems solved by technology

If the adhesive applied to this film is not strong enough, it will be easily peeled off from the film
If the adhesive force is strong, such as tight panty liners are too strong to wear shorts, it is difficult to peel off after use. When in a fixed position, it is difficult to easily peel off
[0004] In addition, when the film is replaced with a non-woven fabric, the following situation may also occur, that is, the adhesive applied on the non-woven fabric moves toward the inside of the non-woven fabric with the passage of time, and it is close to the panty liner. Pads cannot be fixed on wearing shorts

Embodiment Construction

[0023] Hereinafter, the present invention will be specifically described with reference to the accompanying drawings, taking a panty liner which is an absorbent article for treating bodily fluids of the present invention as an example.

[0024] The panty liner 1 shown in the partially cut-away perspective view of FIG. 1 comprises an outer layer 2 forming a contact surface against the user's skin, an inner layer 3 forming a non-contact surface, positioned between these two layers 2, 3 The liquid-absorbent core 4 in between. The outer layer 2 and the inner layer 3 have the same shape and size as the core 4 , and are integrally formed on the bonding line 6 extending along the outer edge of the pad 1 . The outer layer 2 and the core body 4 are also integrally formed in a plurality of recesses 7 formed by embossing the outer layer 2 . On the bottom surface 8 of the inner surface layer 3, a plurality of bonding regions are formed by applying an adhesive 9 covered with a release pap...

Abstract

The invention provides an absorbent article for body fluid treatment in which the inner surface has a viscous fixing area. An absorbent article such as a panty liner 1 for disposal of body fluids discharged thereon includes a body facing side, an undergarment facing side and an absorbent core disposed therebetween, the undergarment facing side including a thermoplastic synthetic fiber layer 12 placed against a bottom surface of the core 4 and having a density lower than that of the core 4, a synthetic resin layer 13 having a density higher than that of the fiber layer 12 and a first thermoplastic synthetic fiber 11 having a density lower than that of the resin layer 13, and the synthetic fiber layer 11 being coated with adhesive agent 9 to an undergarment.

Description

technical field [0001] The present invention relates to an absorbent article for treating bodily fluids, such as a sanitary napkin or a panty liner, which has a fixing mechanism for wearing clothes. Background technique [0002] As is well known, in the past, in absorbent articles such as sanitary napkins or panty liners, the contact surface (non-contact surface to the skin) with respect to wearing clothes was formed by a plastic film, and the adhesive applied to the outer surface of the film The above-mentioned article is fixed on the clothing in a detachable manner. In addition, by substituting the film for an air-permeable material such as a nonwoven fabric, the air permeability of the absorbent article can be improved, and the degree of air impermeability or rash that occurs when the article is worn can be reduced. [0003] Most of the above-mentioned plastic films are olefin-based films such as polyethylene. If the adhesive force applied to such a film is not strong, ...
