  Here, in order to prevent leakage of liquid cosmetics during the period up to the start of the first use such as during transportation and storage, a simple configuration is desired. Since the coating liquid supply body that is also used for preventing leakage is used, the configuration is complicated.

  The present invention has been made to solve such problems, and an object of the present invention is to provide a liquid cosmetic container capable of preventing leakage of the liquid cosmetic at a time until the first use start with a simple configuration. And

  The liquid cosmetic container according to the present invention is a liquid cosmetic container that allows a liquid cosmetic contained in an internal storage chamber to appear by being pushed out from an opening through a flow path, and evaporates water by dissolving a water-soluble polymer in water. It is characterized by having a sealing plug formed on the opening side of the flow path.

  According to such a liquid cosmetic container, the water-soluble polymer is dissolved in water to evaporate the water, so that the sealing stopper provided on the opening side of the flow path is liquid cosmetic for the period up to the start of the first use. While preventing the leakage of the material, at the beginning of the first use, the liquid cosmetic extruded by the user's operation enters the numerous fine holes in the sealing plug, and most of the sealing plug is liquid. As a result of coming into contact with the cosmetic material, the sealing plug becomes soft as a whole and is easily pushed out together with the liquid cosmetic material so that it can be used for the first time. For this reason, it is possible to prevent leakage of the liquid cosmetic material in the period up to the start of the first use with a simple configuration.

  By the way, when liquid cosmetics that have entered the flow path due to vibrations during transportation or storage are in contact with the sealing plug, the liquid cosmetic in the flow path is pushed out. Unlike the liquid cosmetics that come out, it does not enter into the numerous fine holes in the sealing plug, but only the portion of the sealing plug that comes into contact with the liquid cosmetic is soft on the surface. Therefore, the function of preventing leakage of the liquid cosmetic is maintained.

  Here, the water-soluble polymer is preferably a raw material contained in the liquid cosmetic contained in the accommodation chamber from the viewpoint of displaying all components based on the Pharmaceutical Affairs Law.

  Further, when the opening is soaked in a solution obtained by dissolving a water-soluble polymer in water and then the water is evaporated, the sealing plug can be easily formed and the manufacturing cost can be reduced.

  As described above, according to the present invention, it is possible to prevent leakage of the liquid cosmetic material in the period until the first use start with a simple configuration.

  Hereinafter, preferred embodiments of the liquid cosmetic container according to the present invention will be described. FIG. 1 is a longitudinal sectional view showing a liquid cosmetic container according to an embodiment of the present invention. FIG. 2 is an enlarged longitudinal sectional view of a pipe member and a sealing plug employed in the liquid cosmetic container shown in FIG. The liquid cosmetic container according to the present embodiment accommodates the liquid cosmetic inside the container and appropriately pushes it out by a user operation so that it can be used.

  As shown in FIG. 1, the liquid cosmetic container 100 includes a main body cylinder 1 having a storage chamber 1 a for storing the liquid cosmetic L therein, and an operation that is rotatably attached to the rear end portion of the main body cylinder 1. When the user relatively rotates the tube 2, the moving body 5 moves forward or backward in accordance with the screwing mechanism 3 and the rotation preventing mechanism 4 as the pushing mechanism formed in the container 100, and the piston 6 at the tip of the moving body 5 is moved forward. Is fed out toward the front end side of the main body cylinder 1, so that the liquid cosmetic L in the storage chamber 1 a is pushed out toward the front end side, and the liquid cosmetic L that is pushed out is used as a pipe member at the front end portion of the main body cylinder 1. 7 is made to appear in the outside through 7 and discharged to the brush 8 so as to be in a use state. In addition, the structure which has a ratchet mechanism and accept | permits only the advance of the mobile body 5 and the piston 6 may be sufficient as an extrusion mechanism.

  The pipe member 7 includes a holder portion 7a attached to the distal end portion of the main body cylinder 1, and a pipe portion 7b provided in the center of the holder portion 7a and extending forward, and from the rear side of the holder portion 7a. The liquid cosmetic L that is pushed out can appear outside through the opening 7d at the tip of the liquid cosmetic L through the flow path 7c formed in the pipe portion 7b. In addition, the holder part 7a and the pipe part 7b may be separate or integrally molded.

  Here, particularly in the present embodiment, the sealing plug 10 that closes the opening 7d at the tip of the pipe member 7 prevents the liquid cosmetic L from leaking out at the time until the first use is started, such as during transportation or storage. It is provided for the purpose of

  As shown in FIG. 2, the sealing plug 10 has a shape that enters the tip from the opening 7 d of the pipe member 7 and bulges out from the opening 7 d.

  And this airtight stopper 10 uses the water-soluble polymer as the raw material.

  Specifically, an organic substance can be used as the water-soluble polymer, and a natural polymer, a semi-synthetic polymer, or a synthetic polymer can be used as the organic substance.

  Examples of natural polymers include guar gum, locust bin gum, quince seed gum, carrageenan, galactan, gum arabic, tragacanth gum, bectin, mannan, starch, and other plant systems (polysaccharides), for example, xanthan gum, dextran, etc. Microbial system (polysaccharide system) or animal system (protein system) such as gelatin can be used.

  Examples of the semi-synthetic polymer include celluloses such as methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose, and methylhydroxypropylcellulose, and starches such as soluble starch, carboxymethylstarch, and methylstarch. For example, it is possible to use alginic acid type | system | groups, such as a propylene glycol ester alginate and an alginate, and other polysaccharide derivatives.

  Moreover, as a synthetic polymer, it is possible to use vinyl systems such as polyvinyl alcohol, polyvinyl pyrrolidone, polyvinyl methyl ether, carboxyvinyl polymer, and sodium polyacrylate.

  Here, among the water-soluble polymers, the sealing plug 10 is formed using a raw material (one type or plural types) contained in the liquid cosmetic L contained in the container 100. .

  Specifically, the pipe member 7 having the holder portion 7a and the pipe portion 7b is turned upside down in a solution obtained by dissolving the above raw material in water, and the opening 7a is immersed therein. The sealing plug 10 is formed as shown in FIG. Thus, the sealing plug 10 can be easily formed, and the manufacturing cost is reduced.

  As shown in FIG. 1, a pipe member 7 having a sealing plug 10 at the tip and fitted with a brush 8 or the like is used for an extrusion mechanism, a moving body 5, a piston 6, a liquid cosmetic L, and the like. The liquid cosmetic container 100 in which the liquid cosmetic L is hermetically sealed in the container 100 by the sealing plug 10 is obtained by mounting the front end of the assembly built in 2. Note that the liquid cosmetic L may enter the pipe member 7 up to the tip in the pipe portion 7a, or may be accommodated in the accommodation chamber 1a so as to have a space with the sealing plug 10.

  Here, since the sealing plug 10 of the present embodiment is formed by dissolving a water-soluble polymer in water and evaporating the water, when it comes into contact with the liquid cosmetic, it melts in the water contained in the liquid cosmetic and is soft. (According to the experiments of the present inventors, it takes about 30 seconds to 1 minute until the water-soluble polymer comes into contact with the liquid cosmetic and becomes soft). Therefore, when the liquid cosmetic L in the storage chamber 1a is pushed out by the user's operation at the start of the first use, the liquid cosmetic L pushed out is put in many fine holes in the sealing plug 10. As a result, most of the sealing plug 10 comes into contact with the liquid cosmetic L. As a result, the sealing plug 10 becomes soft as a whole and is easily pushed out together with the liquid cosmetic L, and can be used for the first time.

  On the other hand, when the liquid cosmetic L that has entered the flow path 7c due to vibration during transportation or storage is in contact with the sealing plug 10 until the first use starts, the liquid makeup in the flow path 7c. Unlike the liquid cosmetic L that is extruded, the material L does not enter the numerous fine holes in the sealing plug 10, and only the portion of the sealing plug 10 that contacts the liquid cosmetic L is used. Since it is only soft on the surface, the function of preventing leakage of the liquid cosmetic is maintained.

  In other words, in this embodiment, the sealing plug 10 provided on the opening 7d side of the flow path 7c by dissolving the water-soluble polymer in water and evaporating the water is a liquid cosmetic at a time until the start of the first use. On the other hand, at the beginning of the first use, the liquid cosmetic L extruded by the user's operation is easily extruded together with the liquid cosmetic L, and the first use is possible. Leakage of the liquid cosmetic L during the period up to the start of the first use can be prevented with a simple configuration.

  Incidentally, the present inventor obtained the sealing plug 10 by the above-mentioned method using the above-mentioned polyvinyl alcohol or polyvinylpyrrolidone as a raw material, and prevents leakage of the liquid cosmetic L at the time until the start of the first use by the sealing plug 10. On the other hand, it was confirmed that the hermetic stopper 10 was easily pushed out by the liquid cosmetic L pushed out at the start of the first use, and the first use was possible.

  As described above, the present invention has been specifically described based on the embodiment, but the present invention is not limited to the above embodiment. For example, in the above embodiment, in particular, from the viewpoint of displaying all components based on the Pharmaceutical Affairs Law. Preferably, the raw material of the sealing plug 10 is a raw material contained in the liquid cosmetic L contained in the container 100. However, if the raw material for the liquid cosmetic is the liquid cosmetic L contained in the container 100, The raw material which does not contain can also be used, and the raw material of the sealing plug 10 may be a water-soluble polymer.

  In the above-described embodiment, the application to the liquid cosmetic container 100 having the pipe member 7 and the brush 8 is described as being particularly preferable. The present invention can also be applied to a liquid cosmetic container having an applicator.

  In the above embodiment, the application to the rotating liquid cosmetic container 100 having a screw feeding mechanism is described as being particularly preferable. However, for example, a knock type, a tube, a soft bottle, etc. The liquid squeeze container can be applied to a simple squeeze-type liquid cosmetic container.
