JP6067604B2 - Beauty pack base sheet, beauty pack material using the same, and method of manufacturing beauty pack material - Google Patents

Description

  The present invention relates to a beauty pack material covering a face infiltrated with a beauty serum.

  Conventionally, beauty packs have been used for the purpose of replenishing nutrients and moisture for facial skin beauty.

  The beauty pack is applied to the face after a certain time has elapsed after applying a liquid or sol containing active ingredients and a foamed product (hereinafter collectively referred to as “beauty liquid etc.”) to the face skin. Remove the essence and wash your face.

  In general, in order to exert the beauty effect of a beauty serum or the like, the beauty fluid or the like must be kept on the face skin for a certain period of time. Therefore, in the case of a beauty pack, it is necessary to apply the cosmetic liquid etc. evenly over the entire face, and to cover it with a wrapping material so that the cosmetic liquid etc. will not dry or sag. If the viscosity of the liquid is high or foamy, the former takes a lot of work, and if the liquid has a low viscosity, the work related to the latter is large.

  Therefore, for cosmetic liquids with low viscosity, a sheet material that can hold them to some extent is used as a base material, and a cosmetic pack material is prepared by impregnating the base material in advance with a cosmetic liquid. A beauty pack method that covers the face with a pack material has been proposed, and more recently, beauty with added value such as improving the beauty effect as well as the beauty effect by the active ingredient itself contained in the beauty pack material. Pack materials are being developed.

  For example, Patent Document 1 below discloses a beauty pack material in which massage procedures and the like are written in mirror letters for the purpose of facilitating a massage for improving the skin beautifying effect in a beauty pack.

  Patent Document 2 below discloses a beauty pack sheet in which a germanium metal piece is embedded in a flexible resin sheet for the purpose of enhancing the skin beautifying effect by negative ion electronic action.

  In general, beauty pack materials cover the face, so the base material is formed into a circle or ellipse that is about the size of the face, and the mouth and nose can be breathed, conversed, and visually recognized in the pack. -Although holes and cuts are provided in the area corresponding to the eyes, the base material with a specific color tone and texture is stuck to the entire face in the beauty pack, so the face in the beauty pack is beautiful In addition, the personal identification when viewed by others is significantly reduced, and in some cases, unnecessary fear may be generated in the surroundings.

  For this reason, it is natural that the beauty pack should be carried out with eyes, and the conventional beauty pack material has a large limitation on the places and situations (mainly related to the presence of others) that can be practically used.

  An object of the present invention is to provide a beauty pack material with high personal identification even in a beauty pack and a method for manufacturing the same.

  In order to solve the above-mentioned problems, the base sheet for a beauty pack of the present invention is characterized in that a reed cellulose continuous long fiber nonwoven fabric is printed with a gravel pattern made of an oil-based gravure ink by gravure printing.

  According to the base sheet for a beauty pack of the present invention, an unexpected face-to-face appears because the transparency in a state in which a liquid or milky serum is infiltrated is high and the personal identification is high when seen by others. It is expected that the troubles in the case can be reduced than before, and it becomes a beauty pack that can be enjoyed with others by combining it with posing that imitates the performer of Kabuki who is a traditional performing art with a take-off pattern, The place and the situation where a beauty pack can be implemented become wider than a conventional base sheet for a beauty pack.

  In addition, the trimming pattern of the base sheet for the beauty pack of the present invention is obtained by printing oil-based gravure ink on the regenerated cellulose continuous long-fiber nonwoven fabric by gravure printing. Becomes an excellent base sheet for a beauty pack in which elution of ink is suppressed even when the cosmetic liquid is infiltrated.

  In addition, in the base sheet for the beauty pack of the present invention, when the oil-based gravure ink is of a urethane two-component curable type, the spreadability to the regenerated cellulose continuous long-fiber nonwoven fabric is further improved, and the beauty liquid is infiltrated. This is preferred because the elution of the ink and the abrasion resistance are further improved.

In addition, when the basis weight of the regenerated cellulose continuous long-fiber nonwoven fabric that is the base material sheet is too small, the base sheet for the beauty pack of the present invention has a sufficient amount to obtain the effect of the beauty pack even if the cosmetic liquid is infiltrated. The serum cannot be retained. On the other hand, if the basis weight of the base material sheet is too large, excess cosmetic liquid is also retained, and an unnecessary cost increase is generated with respect to the effect of the obtained beauty pack. Therefore, in the base sheet for beauty packs of the present invention, the basis weight is preferably about 80 to 100 g / m ² .

  In addition, in order to solve the above-mentioned problems, the method for producing a beauty pack material of the present invention includes a step of gravure printing an oil-based gravure ink on a regenerated cellulose continuous long-fiber nonwoven fabric, and a regenerated cellulose continuous length printed with the oil-based gravure ink. And a step of impregnating the fiber nonwoven fabric with a cosmetic liquid.

  Therefore, according to the method for manufacturing a beauty pack material of the present invention, it is possible to easily obtain a beauty pack material having an arbitrary pattern that has high transparency at the time of the beauty pack and is difficult to lose color.

  In the method for producing a beauty pack material of the present invention, it is more preferable that the oil-based gravure ink is of a urethane two-component curable type because a beauty pack material that is more difficult to discolor is obtained.

  In addition, in the method of manufacturing the beauty pack material of the present invention, in order to obtain a safer beauty pack material, the oil-based gravure ink is used as an ink made of a raw material that satisfies the NL regulations, or a skin patch test is performed. It is more preferable to confirm skin irritation.
