[0013] Summary of the Invention

[0014] In the following, terms such as “cream” refer to creams, lotions and ointments that are liquid, and may be water and / or oil based.

[0015] Problems to be Solved by the Invention

[0016] Therefore, a main objective of the present invention is to provide a system for covering creams on skin to avoid that the creams are removed from the skin and to avoid damage to the surroundings.

[0017] Means for Solving the Problems

[0018] The objective is achieved according to the invention by a cover skin wrap as defined in the preamble of claim 1 , having the features of the characterising portion of claim A number of non-exhaustive embodiments, variants or alternatives of the invention are defined by the dependent claims.

[0019] The present invention attains the above-described objective by a wrap having a sealing layer on a base layer.

[0020] In a first aspect of the invention, a cover skin wrap for use to cover cream on skin, is provided, wherein the cover skin wrap comprises a base layer, and a sealing layer applied on a first surface of the base layer, wherein the sealing layer has a surface for facing the cream. This ensures that skin can conveniently be treated with cream without leaking cream to the surroundings.

[0021] In one embodiment, the base layer is made of bamboo. Tests show this is comfortable against skin and provides good attachment for a sealing layer.

[0022] In one embodiment, the sealing layer is made of polyurethane. Tests show that this is sealing and sufficiently flexible for comfortable extended use and is compatible with many types of cream.

[0023] In one embodiment, the surface sealing layer is provided with a material having a texture to increase the size of an effective surface of the sealing layer. This increases the effective surface area facing the skin and allows for more cream to be held by the cover skin wrap for further extended use.

[0024] In one embodiment, the cover skin wrap is pre-coated with cream.

[0025] In one embodiment, the sealing layer is provided with a material having an open cell structure on the side facing the skin, to increase an effective carrying capacity of the cream. This way, the sealing layer acts partially as a sponge, so that cream can be applied, or be pre-applied with cream, prior to applying the cover skin wrap in position, and allows for more cream to be held by the cover skin wrap for further extended use.

[0026] In one embodiment, the open cell structure is pre-filled with cream.

[0027] In one embodiment, the cover skin wrap is shaped to fit a specific body part. Certain conditions such as psoriasis tend to show in in specific areas. This makes it possible to mass produce cover skin suited for use for many users and not having to rely on bespoke fittings.

[0028] In one embodiment the base layer of the cover skin wrap is provided with fastening means such as velcro, to adjust the wrap to the size of a given body part.

[0029] In one embodiment, the cream is pre-applied to the sealing layer, such that the user may just put on the wrap and the cream will be applied onto the skin to be treated.

[0030] Effects of the Invention

[0031] The present invention comprises a technological advantage over known systems by being easy and quickly to use, and by arranging the cream at the correct position. Further, the wrap according to the present invention may comprise more cream than easily applied to the skin, and thus the time interval between every time the cream must be applied may be longer.

[0032] The present invention provides several further advantageous effects: it makes it possible to keep the cream in place for longer periods of time, it makes it possible to be physically more active without any leaks, it allows for more unaffected skin to breathe freely, it allows for tailor making the design to the affected skin area.

[0042] Principles Forming the Basis of the Invention

[0043] Fig. 1 shows an embodiment of the invention being prepared, and Fig. 2 shows an embodiment of the invention prepared and positioned. The inventor has recognized that the usability problems with the current approaches such as plastic foil tend to cover too large areas of the body, which through perspiration and tightness causes discomfort and lack of stability in positioning. By applying a localized sealing layer onto a base layer that can breathe, the affected part of the body can be covered efficiently, without the above problems. The base layer can be attached by traditional means or be formed as a tube, sock, or the like to be adapted to the body, thus avoiding the use of adhesives, which can be a problem for several conditions such as psoriasis.

[0044] Fig. 3A shows an embodiment of the invention in position with a cross section, and Fig. 3B shows a cross section of an embodiment of the invention. The cover skin wrap 100 comprises a base layer 110 and a sealing layer 120 applied to the surface of the base layer.

[0045] The base layer is a layer that is comfortable in use over extended periods of time. Typically, it breathes, and can be woven, knitted or be in a similar form of textile. The material should be compatible to skin exposure, such as cotton or bamboo. This will depend on the condition of the user, and it is for instance known that cotton is suitable for psoriasis, but wool is unsuitable.

[0046] During production, the sealing layer can be applied in liquid form or attached using heat, glue or similar, to the base layer. This sealing layer has to seal against the cream used and the material has to be chosen accordingly. It is well known that certain polymers such as latex will work well with water-based materials but will dissolve in oil. It has been found that polyurethane works well. It is preferred that the material is flexible so that the sealing layer fits conforming to the skin, which may cover a body part of complex geometry such as arms. It is also preferrable that the material also is elastic, especially if the base layer also is elastic. This can assist in providing a fit against the skin that stays tight.

[0047] In use, a user has an area 12 of the skin 10 to be treated, typically a small fraction of the entire skin 10 area. Cream 20 is applied to the skin area to be treated, and a cover skin wrap is positioned so that the sealing layer 120 comes in contact with the cream 20. The cover skin wrap can be available in various sizes and shapes and selected for the size of the area to be treated, as well as designed to fit the part of the body to be treated. In the case of psoriasis, the area may be limited to areas near the elbows or near the knees, so the sealing layer 120 can be made smaller than the overall base layer 110.

[0048] In use, the area of the skin to be treated 12 is covered with cream 20 but is not in contact with the textile that can be part of the base layer 110. The sealing layer 120 is selected to be compatible with the skin, though when the cream is absorbed into the skin, it is expected that more cream will be added to the skin so that once again the entire skin area to be treated is properly covered with cream.

[0049] Best Modes of Carrying Out the Invention

[0050] Presently, the use of a polyurethane sealing layer on a base layer of bamboo fabric is considered a well working combination.

[0051] While the base layer is suitable for attachment and fixing the sealing layer into position over the cream by traditional means, it is considered that making the base layer in the form of tubes or socks is particularly convenient, for instance by sewing or weaving or knitting to shape.

[0052] In use, the tube is partly rolled back, slid forward towards the cream applied area, at which point the tube is rolled over so that the skin area 12 to be treated is entirely covered by the sealing layer.

[0053] Fig. 4 shows an embodiment of the invention adapted for a knee, where the base layer 110 extends in a substantially tubular form with elastics or elastic bands 112 at the two ends of the tubular form. This means there is little compression at the knees where psoriasis commonly occurs, providing a gentle fit near the affected areas. A sealing layer 120 is provided at an area corresponding to the knee when worn. The structure means that the cover skin wrap can be adjusted positionally for optimum treatment of the affected areas.

[0054] Fig. 5 shows an embodiment of the invention adapted for an elbow, which is typically a slimmer structure of the version for knees.

[0055] Elastic 112 areas for fixing the cover skin wrap in place are preferably positioned at the ends of the tubular forms, so to avoid engaging with skin to be treated or interfere with the sealing layer. Preferably, the elastic areas are elastic bands that are parts of or sewn in the base layer 110. The sealing layer can be provided in a wide range of areas, depending on need and the size of the area to be treated.

[0056] Alternative Embodiments

[0057] A number of variations on the above can be envisaged. Fig. 3C shows an embodiment wherein the sealing layer 120 surface 130 is provided with a surface texture 132. The surface texture can hold more cream and form a limited reservoir and provide cream application for an extended period of time compared to a smooth surface. The surface should be adapted to the use, for instance it is strongly preferred that in the case of psoriasis the surface is not abrasive. A smooth surface 130 is easier in production and is easier to clean between uses.

[0058] The surface can be pre-coated with cream, optionally protected by a pull-off film, to avoid spilling cream and increase convenience.

[0059] Fig. 3C also shows another variation, wherein the sealing layer 120 comprises at least partly an open cell structure 122 that is open to the surface 130. This way, the sealing layer acts partially as a sponge, so that cream can be applied, or be preapplied with cream, prior to applying the cover skin wrap in position.

[0060] It is preferred that the sealing layer materiel itself does not absorb any cream, but may comprise a material having a texture and / or open cell structures, and this material may contain the cream.

[0061] The use of one or more materials having an open cell structure 122 and surface texture 132 can be combined and can also be used with same or different creams. This can provide time dependent treatment, as the cream or creams are absorbed.

[0062] The sealing layer can be substantially flat or be sculpted with topological features such as curves and elevations resembling body parts. For instance, an adaption for receiving and / or protecting elbows or knees can be provided. Polyurethane is a material that can be made in a range of hardnesses and can provide a flexible sealing layer and sculpted protection for the affected areas.

[0063] Also, one or more sealing rings can be provided along the periphery of the sealing layer, forming an edge in order to further prevent leakage of cream. Industrial Applicability

[0064] The invention according to the application finds use in treatment with creams and protection for clothing. The cover skin wrap can be unobtrusively used under normal clothing or in bed without causing damage to garment or bed linen.
