Description

  The present invention relates to a stick-shaped cosmetic having a concavo-convex pattern.

  From the viewpoint of aesthetics, sticky cosmetics such as sticky lipsticks are preferred to have glossy surfaces, and glossy sticky cosmetics attract consumers' hearts. In order to gloss the surface of the stick-shaped cosmetic material, the inner surface of the cavity or the Ogibe formed in the mold as a molding die is made as smooth as possible, and the surface is made smooth with no irregularities.

  However, although such stick-shaped cosmetics are beautiful in design, when they are used, cosmetics are applied when an unused part of the stick-shaped cosmetics is applied to the skin, such as at the beginning of use of a new cosmetic after production. The material does not adhere well to the skin, such as the lips, and it must be pressed firmly to secure it, giving it a discomfort. Also, the first touch on the skin application site such as lips is felt hard, which is also uncomfortable.

  On the other hand, stick-shaped cosmetics in which a concavo-convex pattern is partially formed to give a design value to the surface of the stick-shaped cosmetics have been developed (see, for example, Patent Documents 1 and 2). These are also beautiful in design, but when used, the uneven pattern gives the skin such as the lips an uncomfortable feeling such as a sensation and is not uniformly applied. In addition, the amount of new cosmetics after manufacture is not sufficient when applied, and the first touch on the skin such as lips is hard.

  3 to 6, the same reference numerals are given to the same parts as those in the embodiment according to FIGS. 1 and 2.

  As described above, in each of the embodiments, (1) a concavo-convex pattern including a plurality of point-like protrusions 20 and (2) a concavo-convex pattern including one or a plurality of linear protrusions 50 have been shown. Such a stick-shaped cosmetic is provided with protrusions that form a continuous pattern of unevenness on at least the entire tip portion of the surface of the stick. The concavo-convex continuous pattern is a pattern in which the concavo-convex pattern is a continuous pattern by providing the same or different protrusions in close proximity and continuously.

  In producing the stick-shaped cosmetic according to the present invention, the method is not particularly limited. For example, a conventional stick-shaped cosmetic using a stick-shaped cosmetic mold provided with the uneven pattern according to the present invention on the inner surface is used. Is performed by a method of molding. As the mold, for example, a general mold such as Ojibe (plastic mold, silicone mold, rubber mold, etc.), a split mold in which a cavity is formed is used. Further, a pattern may be formed by directly irradiating, for example, a laser beam, on a stick-shaped cosmetic material without an uneven pattern formed by a normal mold.

  Specifically, for example, in the case of Ojib molding, an irregularity forming portion consisting of an irregularity portion corresponding to the irregularity pattern formed on the surface of the stick-shaped cosmetic is provided in a predetermined region on the inner surface of the Ogiave, and the molten stick is provided on the Ojive. A stick-shaped cosmetic is produced by filling the cosmetic composition and cooling and solidifying it. As a result of the molding process of the stick cosmetic, the uneven portions formed on the Ojib are transferred to the stick cosmetic.

  The formation of the concave-convex forming portion on the inner surface of the Ojive is not particularly limited, but, for example, is based on a method in which an Ojive mold (= master mold) is provided with an uneven pattern and an Ojive is molded.

  The concave / convex pattern of the Ojib mold is formed by various processing methods such as an electric discharge machining method performed by electric discharge, an etching method performed by dry or wet etching, or a laser processing method performed by irradiating laser light. Is done.

  In addition, in the case of molding with a split mold, it is basically the same as the above-mentioned method by Ojib, and a concavo-convex pattern formed on the surface of the stick-shaped cosmetic material in a predetermined region on the inner surface of the cavity formed in the mold body. A concavo-convex forming portion comprising a corresponding concavo-convex portion is provided, and a stick-shaped cosmetic is produced by filling the cavity with a molten stick-shaped cosmetic composition and solidifying by cooling. As a result of the molding process of the stick-shaped cosmetic material, the uneven portions formed in the cavity are transferred to the stick-shaped cosmetic material.

  As a method for forming the concave and convex portion on the inner surface of the cavity, means such as engraving and laser are used. Further, similarly to Ojib, a method for forming a split mold by forming a concave / convex pattern on the split mold is also possible.

  The method for forming the uneven pattern of the split mold is the same as in the case of Ojib.

  The stick-shaped cosmetic material in the present invention is not limited to the lipstick 10 shown in the above embodiment, and may be anything as long as the skin (skin) is applied. Among them, the lipstick 10 is preferable because a remarkable effect can be obtained.

  According to the present invention, the effect of the present invention is exerted when an unused part of a stick-shaped cosmetic is applied to the skin. This effect is obtained as long as the protrusions forming the continuous pattern of unevenness according to the present invention do not disappear. It is demonstrated without being limited to unused parts.

  Hereinafter, the present invention will be specifically described with reference to examples. Prior to the description of the examples, the effect test method used in the present invention will be described.

  The following usage tests were conducted by 20 specialist panels. A first-touch feel, a lipstick 10 stick, etc., when manufactured and used in a normal manner using a stick-like cosmetic such as lipstick 10 and applying an unused part of the stick-like cosmetic to the skin Each of the evaluation items of the adhesion of the cosmetic to the skin such as lips, the feel of the skin such as lips at the time of application (discomfort etc.) and the uniformity of application was evaluated based on the following evaluation criteria. Subsequently, the average score of the evaluation points given by each person was calculated and evaluated based on the following evaluation criteria.
