Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an article, particularly made of a flexible material, that comes into direct contact with the user's skin or mucous membranes when worn as a belt or worn.

It is well known that certain materials contain allergens and irritants that can cause unpleasant skin irritation or allergies when worn or worn by people with skin sensitivities. ing. Such materials include, in particular, leather and leather-like materials;
From these products, we manufacture ordinary and special gloves, sweat bands for hats and helmets, watch bands, other bands, protective clothing (for doctors and nurses), protective shoes, orthopedic materials, and other medical products. I am forced to do so. The same can be said of synthetic resins, rubber, and rubber-like materials, for example in the form of thin films or textiles.

The object of the invention consists in producing the above-mentioned article in such a way that skin irritation and allergy can be eliminated without adversely affecting the usability.

According to the invention, this problem is solved by the article having a barrier layer which prevents allergens and irritants from coming into contact with the material towards the skin, at least when the article is used on the skin of a user. It was solved by

The barrier layer used in the present invention prevents the material of the article from coming into direct contact with the skin or mucous membranes of the wearer. The horny skin itself prevents allergens and/or stimulants from penetrating into the core of the skin, but for example, horny skin that does not form on the joints of the arm where a watch is worn, the forehead and buttocks, etc. take on the functions of Moreover, the metal layer or the layer in which metal powder is contained in a binder (hereinafter simply referred to as metal layer) allows the article to be used, for example, when wearing a watch while taking a bath,
This protects the wearer from moisture, such as when the wearer practices sports and sweats. This function is particularly important because sweat dissolves allergens from materials, resulting in hypersensitivity. Moreover, the mechanical properties of the article, ie, for example, the abrasion resistance, can also be improved by the barrier layer.

Thin metal layers are particularly suitable within the scope of the invention, but also thin lacquer layers containing metal powder. Particularly suitable are the sizes of the metal powder particles, which correspond to the known metallic bronzes used as luster pigments in the lacquer technique.

Within the framework of the invention, adhesives can be present between the material and the barrier layer. The adhesive may be a synthetic resin layer, such as a lacquer layer. By means of this intermediate layer, any pores or irregularities present in the material are closed and evened out, so that a virtually pore-free coating is created. By coloring the adhesive layer in a contrasting color to the barrier layer, there is also the possibility of signaling in case of breakdown or abrasion of the barrier layer to allergens and/or stimulants.

In principle, all extensible metals are suitable as metals for the metal layer. Particularly suitable within the scope of the invention are aluminum and precious metals and especially pure gold.

Usually the metal layer has a thickness of 150 μm to 500 μm. The preferred thickness is between 200 and 350 μm.

In the case of aluminum coatings, a thickness of 260 μm, for example, is particularly suitable. This barrier layer, however, does not have to be flat. In this case, it can have a protrusion in the shape of a spherical cutout. The layer then does not come into contact with the skin over its entire surface. Protrusions can be easily formed by increasing the layer thickness.

Claims (1)

[Claims] 1. Articles that are used in direct contact with the wearer's skin or mucous membranes, at least in the part that comes into contact with the skin or mucous membranes during use, and have a thickness of 200 mm or more.
A layer of 350 μm of aluminum or precious metal, or aluminum or precious metal embedded in a binder, that allows allergens and/or irritants contained in the material of the article to be transferred from that material onto or from the wearer's skin, respectively. 1. An article made of a flexible material used in contact with the skin, characterized in that a continuous barrier layer is formed to prevent seepage into the interior. 2. The article according to claim 1, wherein the binder is a synthetic resin or a fired enamel lacquer. 3. The article according to claim 1 or 2, further comprising an adhesive layer between the barrier layer and the article. 4. The article according to claim 3, wherein the adhesive layer is a synthetic resin or fired enamel lacquer. 5. An article according to claim 3 or 4, wherein the adhesive layer is of a color that contrasts with the color of the barrier layer. 6. Article according to claims 1 to 5, wherein the barrier layer is formed from hemispherical projections or locally compressed layers.
