Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to skin for human body models used when applying and peeling off cosmetics many times in cosmetic practice, cosmetic sales demonstrations, etc. This relates to its manufacturing method.

Conventional technology Human model skin has been used for repeated application and peeling of cosmetics in cosmetic practice, cosmetic sales demonstrations, etc., but in both cases, the adhesion of cosmetics Not only is it bad, but it also has poor removability of cosmetics once attached.
This had the disadvantage of causing problems in the next application of cosmetics.

Also, due to this drawback, cosmetics are not directly applied to the skin of the human model, but instead a film is formed on the skin of the human model using a cosmetic pack agent, as in the invention described in Japanese Patent Publication No. 45-34610, and cosmetics are applied to this film. However, it takes a long time to dry after applying the pack, and if there is even a slight failure, the pack must be removed and the makeup must be reapplied from the beginning. However, it did not have any problems.

In addition, there are devices that use silicone rubber to make it easier to peel off applied cosmetics, such as the idea described in Japanese Utility Model Application Publication No. 54-87869. Since silicone rubber, which inherently has poor adhesion, is used as it is without any special processing, it has the disadvantage that the adhesion of cosmetics is poor and the cosmetics cannot be applied reliably.
In addition, because its structure is significantly different from that of real human skin, it is extremely unsatisfactory as a skin for human models, and it is used in makeup practices that require extremely delicate aesthetic sensibilities. It was completely unsuitable for use in demonstrations, etc.

Problems to be Solved by the Invention The present invention attempts to solve the above-mentioned problems, and is intended to solve the problems described above. It has good adhesion similar to that of human skin, and it is easy to remove applied cosmetics with cleansing cream, etc., making it possible to use it many times. The aim is to make it possible to obtain a similar feel.

Means for Solving the Problems The present invention solves the above problems by:
A film part made of a soft elastic material is formed on the surface of an elastic fleshy layer formed of an elastic material having elasticity, and a skin part made of silicone rubber with a satin-like unevenness formed on the surface is peeled off from the outer surface of this film part. It is something that is impossible to form.

This method of manufacturing skin for a human body model involves forming an elastic fleshy layer by foam-molding an elastic material into the desired human body shape, and then applying liquid resin made of a soft elastic material to the surface of this elastic fleshy layer. The process of forming a film by coating the film, spraying a silicone rubber liquid onto the surface of the film, waiting for the sprayed silicone rubber liquid to solidify, and spraying again is repeated multiple times. By repeating this process, a skin portion having satin-like unevenness is formed on the surface of the film portion in a manner that cannot be peeled off.

Effect Since the present invention is configured as described above, satin-like unevenness is formed on the surface of the epidermis, so even when a finger comes into contact with the skin, the satin-like unevenness makes it similar to human skin. You can get a firm contact resistance feeling and apply lipstick, lipstick, etc. to the epidermis.
When a topical cosmetic such as eye shadow or foundation is applied, the cosmetic adheres to the epidermis like human skin without peeling off. The reason why cosmetics adhere so well to the surface of silicone rubber, which originally has poor adhesion, is not entirely clear, but it is believed that the anchor effect is caused by the satin-like unevenness formed on the surface of the epidermis. Seem.

In addition, the surface of the skin on which this cosmetic is applied has a satin-like unevenness, which corresponds to the stratum corneum of the human body, which has many unevenness.
The membrane part made of a soft elastic material located on the inner surface of the epidermis corresponds to the epidermis of the human body, and the elastic fleshy layer formed of an elastic material on the inner surface of the epidermis corresponds to the dermis of the human body. The human body model skin of the invention is extremely similar to human skin. Therefore, when you touch the epidermis with your fingers, it has the same elasticity as human skin, allowing you to get a more realistic skin sensation when practicing makeup, etc., and remove cosmetics that have adhered to the epidermis. When removing with cream etc., this elasticity deforms the satin-like unevenness and allows the wiping tool such as tissue paper to come into contact with the recesses, ensuring that the cosmetic is removed from the epidermis. shall be. In addition, the satin-like unevenness formed on the epidermis is formed by spraying silicone rubber liquid multiple times on the surface of the coating, so unlike when it is formed using a mold, etc., it resembles human skin. It is possible to form fine irregularities, and to obtain good adhesion of cosmetics.

EXAMPLE An example of the present invention will be described below with reference to the drawings. An elastic material made of polyvinyl chloride resin foam material having elasticity is foam-molded into a desired human body shape 1 such as a head and shoulders in a mold. By doing so, an elastic fleshy layer 2 is formed, and then a film portion 3 is formed by applying a liquid resin made of a soft elastic material such as acrylic latex to the surface of this elastic fleshy layer 2. This film part 3
By spray coating or mixing paint on the surface, it is formed into a skin color, and the contours of the eyes 4, eyebrows 5, lips 6, nose 7, stains, freckles, moles, etc. are added to the surface as necessary. I will write it down briefly.

Next, a transparent silicone rubber is sprayed onto the surface of this film part 3 to form a skin part 8. This spray coating of the skin part 8 is performed by roughly spraying the silicone rubber liquid with a spray gun using a spray gun with a large spray particle size, and then heat-treating it in a hot atmosphere at 80 to 90 degrees Celsius after this coating. , harden by leaving at room temperature.
The process of applying silicone rubber liquid to this cured film using a spray gun using a spray gun with a smaller spray particle size than the first time, and curing the same, while gradually decreasing the spray particle size, is repeated multiple times. Thereby, the skin part 8 having the satin-like unevenness 10 on the surface of the film part 3 can be formed in a manner that cannot be peeled off.

Next, we will discuss test piece A in which the skin part 8 was formed by spraying the silicone rubber liquid on the coating part 3 twice with a spray gun, test piece B in which the silicone rubber liquid was sprayed four times, and test piece C in which the silicone rubber liquid was sprayed six times. , conducted tests on the adhesion and removability of cosmetics. The test method is to test the above test pieces A, B, and C, each with a length of 100 mm and a width of 50 mm.
After applying lipstick to the entire surface of test specimens A, B, and C with a thickness of 5 mm, cleansing cream was applied on top of the applied lipstick to make the lipstick stand out.
One test was conducted by wiping this off with tissue paper. As a result, after 350 tests, no dye staining was observed in any of test specimens A, B, and C, and the adhesion of the lipstick was good.

Effects of the Invention As described above, the present invention has a satin-like unevenness formed on the surface of the epidermis, so even when the fingers touch the surface, the satin-like unevenness makes a firm contact similar to that of human skin. When applying cosmetics such as lipstick, eye shadow, foundation, etc., the cosmetics can be applied in the same manner as human skin without peeling off from the epidermis.

In addition, the epidermis to which this cosmetic is applied is connected to an elastic fleshy layer made of an elastic material through a membrane made of a soft elastic material, so when the epidermis is touched with a finger or hand, It has elasticity similar to that of human skin, allowing you to experience a more realistic skin sensation when practicing makeup, etc., and when removing cosmetics that have adhered to the epidermis with cleansing cream, etc. Since the satin-like unevenness is deformed and a wiping tool such as tissue paper can be brought into contact with the recessed portion, the removal of the cosmetic from the epidermis is ensured.

In addition, the satin-like unevenness formed on the epidermis,
Because it is formed by spraying silicone rubber multiple times on the surface of the coating, unlike forming with a mold etc., it is possible to form fine and complex irregularities similar to human skin, making it suitable for cosmetics. This makes it possible to obtain excellent adhesion, making it ideal for cosmetic procedures that require a high level of aesthetic sensibility and extremely delicate work.

In addition, even if you make a mistake during makeup work, the epidermis is formed in the film so that it cannot be peeled off, so you can continue applying makeup by removing only the failed part. As shown in the figure, there is no need to go through the trouble of starting over from the beginning.
