Perspiration insert

Abstract

The invention relates to a perspiration pad for insertion into the armpit with an absorbent pad (2) consisting of two mutually bendable sections and a self-adhesive film (3) projecting beyond the edge of the pad. In order to provide advantageous constructional conditions it is proposed that the self-adhesive film (3) is interrupted at least in the bending region of the two sections of the pad (2).

Description

FIELD OF THE INVENTION [0001] The invention relates to a perspiration pad for insertion into the armpit with an absorbent pad consisting of two mutually bendable sections and a self-adhesive film projecting beyond the edge of the pad. DESCRIPTION OF THE PRIOR ART [0002] For absorbing perspiration in the armpit it is known (U.S. Pat. No. 2,818,572) to adhere an underarm absorbent pad to the skin of the armpit. The absorbent pad comprises a self-adhesive film which projects beyond the edge of an absorbent pad consisting of two mutually bendable sections. In order to facilitate the bending of the absorbent pad, the pad is provided on the one hand with a two-part and overlapping configuration in the bending region and on the other hand the self-adhesive film is provided with a configuration that does not project in the region of the pad. Since the pad does not rest completely on the skin due to the overlapping pad parts, the perspiration originating there cannot be absorbed by the absor...

Benefits of technology

[0006] If the perspiration pad does not have a self-adhesive film in the bending region, the tensile stress produced by bending the perspiration pad is absorbed by the pad. It merely needs to be ensured during the application of the perspiration pad that the region which is free of the adhesive film rests on the axillary arch. A transmission of the tensile stress onto the self-adhesive film is prevented by the elasticity of the pad, thus considerably improving the wearing comfort of the perspiration pad. The provision of a continuous pad ensures a complete application on the skin in an advantageous manner, so that perspiration is absorbed immediately by the pad and therefore no odors can be produced.

[0007] If the perspiration pad comprises at least one curved bending line in the bending region it is possible to improve the bending properties of the perspiration pad and the wearing comfort. Especially in the case of newly inserted perspiration pads a bending is thus already predetermined which is adjusted to the axillary arch, as a result of which bulging in the bending region can be prevented.

[0008] If the self-adhesive film is placed in the form of boundary strips on the edges of the pad sections, the elasticity of the pad will not be influenced by the self-adhesive film, which thus improves the application of the pad on the skin. Moreover, tensile stress which arises between the boundary strips of the self-adhesive film are absorbed by the pad and are not transmitted onto the skin, which thus increases the wearing comfort.

[0010] In order to ensure the elasticity of the pad which is required for absorbing the tensile stress, the pad can preferably be made of an elastic, deformable and / or soft material and be provided with a single-layer and multi-layer configuration. The elasticity can be improved even further by embedding expansion strips in the pad. It is understood that both the pad as well as the self-adhesive film must consist of a skin-friendly material. In order to counteract perspiration odor, the pad can be laced with a perfuming agent and / or with odor-suppressing preparations. Aluminum chlorate has proven its worth for reducing perspiration, which can also be embedded in the pad.

[0011] If the perspiration pad is provided with a trapezoid configuration then this opens up the possibility of providing differently large pad sections according to the number of sweat glands in the axillary arch. It is thus possible to provide the pad section above the axillary arch which is of smaller surface area and, as is already known, has a tapering in the direction of the upper arm, and to ensure a high absorbent effect of the larger part below the axillary arch. It can thus further be prevented that the perspiration pad projects from the armpit and thus will become visible when worn.

[0012] The welding of the self-adhesive film with the pad in the boundary region of the pad ensures that both the resistance against tensile stress is increased as well as the need for material for the self-adhesive film is reduced, because the comparatively large area of overlap of pad and self-adhesive film which is required for a tenacious adhesive connection is reduced.

Problems solved by technology

An especially disadvantageous aspect in these kinds of absorbent pads is, however, that the tensile stress occurring in the bending region are transmitted via the self-adhesive film onto the skin, causing a distortion of the absorbent pad on the skin.

Since the armpit contains a comparatively large number of nerve cells and hair-forming cells, such distortion is perceived as very painful, thus strongly limiting the comfort of the absorbent pad.

Although it is possible to reduce the tensile stress arising in the bending region with this perspiration pad, it cannot prevent that tensile stress between the two pad parts of the perspiration pad which are separated by the axillary arch are transmitted, so that such perspiration pads are not suitable for the armpit.
