Description

  The present invention relates to a double tube container, and more particularly to a double tube container that can store a strong alkaline hair dye 1 or the like.

  Conventionally, hair dye tube containers are usually sold as a set in which one agent and two agents are housed in separate tube containers. The first agent is mainly a basic oxidation dye, and is housed in a sealed aluminum tube container that does not allow gas and liquid to pass through. The second agent is a peroxide that has the purpose of oxidative polymerization of the dye of the first agent. The main content is hydrogen, and a synthetic resin inner bag with excellent gas permeability is fitted inside the metal aluminum tube container. Has been. This is because when the content of creamy hydrogen peroxide as the main component comes into direct contact with the inner surface of a metal aluminum tube container, the inner surface of the aluminum tube container reacts with the content of hydrogen peroxide as the main component. This is because the inner surface of the aluminum tube container is corroded.

FIG. 9A is a partially cutaway cross-sectional view showing an aluminum tube container 50 that houses the first agent. The aluminum tube container 50 is manufactured by impact-molding aluminum slag, and a mouth portion 52 having a sealing lid 51, a shoulder portion 53, and a body portion 54 are integrally formed. After the first agent is stored in the aluminum tube container 50, a cap 55 having a needle body (not shown) is screwed into the male screw portion 52 a of the mouth portion 52, and the mouth portion 52 is sealed. Yes. And when opening the sealing lid 51 of this aluminum tube container 50, it was opening by piercing with the needle body of this cap 55. The reason for storing in the tube container with the sealing lid 51 in this way is that it is easily altered by the inflow of outside air.

Moreover, FIG.9 (b) is a partially notched cross-sectional view which shows the double tube container 60 which accommodates a 2nd agent. In the figure, reference numeral 60 denotes an aluminum tube container in which a mouth portion, a shoulder portion, and a trunk portion are integrally formed. Inside the aluminum tube container 60, an inner bag 61 made of a synthetic resin such as polyethylene and integrally formed with a mouth portion, a shoulder portion and a trunk portion is fitted. Then, as shown in FIG. 9B, the distal end of the mouth portion 62 of the inner bag 61 is folded outward so as to wrap around and cover the distal end of the mouth portion 62 of the aluminum tube container 60, and the inner plug body 63 is formed from above. It is press-fitted. A cap 64 is screwed onto the inner plug 63. As described above, the tip of the mouth portion 62 is bent outward and covered, thereby preventing the contents from adhering to the mouth portion 62 of the metal portion and corroding the mouth portion 62.

  The conventional double tube container for storing the second agent is oxygen generated by the decomposition of the content mainly composed of hydrogen peroxide, and the gap between the opening of the double tube container and the inner plug body and the aluminum tube container. By intentionally releasing to the outside from the bottom of the tube container (b in FIG. 10) and the tube container bottom (b in FIG. 10), the double tube container is prevented from being expanded and ruptured by being filled and pressurized with oxygen. It was. And in the conventional tube container for hair dyes, at the time of use, 1 agent and 2 agents were extracted and mixed in the tray, respectively, and it mixed and applied to hair. As a conventional document, there is Patent Document 1.
