The invention relates to a dermal adhesive tape

• - a carrier layer,
• - At least one active ingredient layer having skin-adhesive properties and arranged on the carrier layer and
• - A protective sheet detachably connected to the active substance layer and covering it.

Dermal adhesive tapes of the type mentioned at the outset are known in various configurations from the prior art and are used to deliver active ingredients to the skin in a location-specific manner and with a high degree of effectiveness.

In sports medicine and orthopedics, dermal adhesive tapes are used as an accompaniment to therapy, for example for bruises, overused joints or muscle complaints. Dermal tapes of this type are also known as kinesiology tapes. It is also known to add adhesives to the active ingredient layer in order to ensure a high level of adhesion to the skin and the associated higher efficiency and precision of the therapy, as is the case, for example, with warming dermal adhesive tapes in order to alleviate pain.

Another area of dermal adhesive tapes comprises cosmetic dermal adhesive tapes that are used, for example, to remove blackheads or have active ingredients with cosmetic properties that are intended, for example, to reduce the depth of wrinkles and thus smooth the skin. The use of dermal adhesive tapes in hair removal is also known.

In principle, before using the dermal adhesive tapes, it is necessary to peel off the protective sheet protecting the active substance layer from the active substance layer. In order to ensure particularly easy handling of the dermal adhesive tape with the protective sheet, the protective sheet usually has a plastic layer. Particularly in applications in which the dermal adhesive tape has to be changed frequently, there is a large number of peeled protective sheets, which are environmentally harmful plastic waste.

The invention is based on the object of providing a dermal adhesive tape that can be used sustainably.

The invention achieves the object by means of a dermal adhesive tape with the features of claim 1. Advantageous developments of the dermal adhesive tape are specified in the dependent claims.

It is characteristic of the dermal adhesive tape according to the invention that the protective sheet is formed from a composite material based on natural fibers. The dermal adhesive tapes according to the invention with a protective sheet formed from natural fiber-based composite material have the advantage over the prior art adhesive tapes that the disposal of the protective sheets pollutes the environment to a far lesser extent since they are made from environmentally friendly materials. Natural fiber-based materials are resource-saving and biodegradable. Furthermore, the protective sheets can be produced inexpensively.

The selection of the natural fiber-based composite material for the production of the protective membrane is fundamentally freely selectable. According to a preferred embodiment of the invention it is provided that the protective sheet is formed from cellulosic material, in particular from paper. Cotton, hemp, jute and flax can be used here. Combinations of the cellulose-containing materials mentioned are also possible. These materials are characterized by the fact that they are produced in a particularly environmentally friendly manner and can then be disposed of.

The color of the protective sheet and the carrier layer can be chosen as desired. In order to ensure particularly user-friendly handling, it is provided according to a particularly preferred embodiment of the invention that the protective sheet and / or carrier layer have a color that is an indicator of the active substance in the adhesive layer.

Here, the protective sheet and carrier layer can have the same color. Furthermore, the protective sheet and / or carrier layer can also be partially marked, for example only at the edges of the protective sheet and / or carrier layer. According to a further embodiment of the invention, patterns in different colors can also be indicators for different active substances. A separate pattern can thus be provided for each active ingredient, which further increases the safety of use.

The material of the carrier layer on which the active substance layer is arranged and via which the active substance layer is attached to the body can be largely freely selected. According to a particularly advantageous embodiment of the invention, however, it is provided that the carrier layer contains cellulosic material, in particular cotton. It has been shown that cotton is particularly rare causes dermatological complications. Alternatively, hemp, jute, flax and / or combinations can be used. The use of a carrier layer made of cellulosic material increases the environmental compatibility of the dermal adhesive tapes in a complementary way.

According to a further advantageous embodiment of the invention, the carrier layer is breathable, water-resistant and / or elastic. A breathable carrier layer ensures sufficient oxygen supply to the skin in order to achieve an optimal environment for the absorption of active ingredients. According to a further preferred embodiment of the invention, the carrier layer is water-resistant in order to prevent water from penetrating the active substance. Mixing water and active ingredient can lead to a dilution of the active ingredient and thus impair the effectiveness of the active ingredient. In order to ensure a precisely fitting adhesion to any part of the body, such as for example the knee or shoulder, the carrier layer is elastic according to a preferred embodiment of the invention. The range of motion, also known as the range of motion (ROM), is not restricted here.

Any skin-friendly adhesive can be used to ensure that the active substance layer arranged on the carrier layer adheres to the skin. According to a particularly advantageous embodiment of the invention, it is provided that the active substance layer has an adhesive, in particular a medical pressure-sensitive adhesive. Medical pressure sensitive adhesives are dermatologically tested and guarantee dermatological compatibility. The risks of dermatological complications are particularly reduced.

The arrangement and configuration of the active ingredient layer can be freely selected. For example, the active ingredient layer can be applied flatly to the carrier layer. According to a particularly preferred embodiment of the invention, however, it is provided that the active substance layer is arranged in a serpentine, strip-like and / or point-like manner on the carrier layer. This ensures that the elasticity properties of the carrier layer are not restricted in order not to reduce the range of motion associated therewith. Furthermore, the active ingredient layer can be applied precisely to the part of the body to be treated.

According to an advantageous embodiment of the invention, it is provided that the elasticity properties of the carrier layer are designed in such a way that flat contact with the body shape is ensured. The body shape can extend over parts of the body such as the shoulder or knee, for example, which requires a minimum elasticity of the carrier layer. The stimulation and stimulation of flat parts of the body is guaranteed. According to a further preferred embodiment of the invention, it is provided that the carrier layer has elastic properties that are similar to the elastic properties of muscles. Precise action on reflex zones is advantageous in order to ensure optimal stimulation. The active ingredients of the active ingredient layer can support and intensify the effect.

In principle, the outer contour of the carrier layer can be freely selected. According to an advantageous embodiment of the invention, however, it is provided that the carrier layer has an outer contour that is adapted to the receiving part of the body. In order to ensure an exact fit on heavily moved body parts such as for example the shoulder or knee, it is advantageous to adapt the outer contour of the carrier layer to the body part mentioned at the beginning. Here, shapes that are adapted to the body part, such as circles, butterflies or stripes, have proven to be advantageous. In the area of facial use, the carrier layer can also have a shape corresponding to the part of the face, such as, for example, cheekbones, chin or forehead-shaped.

The surface of the side of the carrier layer facing away from the active substance layer can in principle be configured as desired. According to a particularly advantageous embodiment of the invention, however, it is provided that the side of the carrier layer facing away from the active substance layer has a surface for receiving cosmetic articles, in particular foundation. The focus here is on the aesthetic aspect of the dermal adhesive tape. In the case of use on the face or on a part of the body not covered by clothing, the dermal adhesive tape can be concealed using cosmetic cover products such as foundation. Different shades of masking products can be combined to achieve the best possible color result.

In principle, the active substance layer can absorb any type of active substance. According to a particularly preferred embodiment of the invention, however, it is provided that the active ingredient layer contains at least one cosmetic active ingredient, in particular for reducing wrinkles and smoothing the skin. The site-specific application of the invention allows precise application of the active ingredient at a desired location.

As already described, the carrier layer, active ingredient layer and / or protective sheet can be formed from different materials. According to a particularly advantageous embodiment of the invention, it is provided that the carrier layer is made from a cotton-elastane fabric and / or the active ingredient layer is made from an acrylate-active ingredient adhesive and / or the protective sheet is made from back paper. The mixture of cotton with elastane has optimal elasticity properties, while cotton is particularly kind to the skin. The active ingredient layer preferably has a mixture of acrylate, active ingredient, particularly preferably “beauty ingredients”, and adhesive. Acrylates serve as binders as well as adhesives and have proven to be particularly advantageous as a basis for mixing with active ingredients. The protective sheet is particularly preferably formed from back paper, which can both be easily peeled off from the carrier layer with the active ingredient layer and is particularly sustainable.
