DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic container for containing an acidic or alkaline liquid or emulsion cosmetic which requires gas barrier properties.

[0002]

2. Description of the Related Art Some cosmetics are in liquid or emulsion form, contain acidic or alkaline components, and are required to have gas barrier properties. Agent and perm agent
One agent and a second agent are included.

[0003] Hair dyes for dyeing hair are classified into temporary hair dyes, semi-permanent hair dyes and permanent hair dyes on the basis of the persistence of the hair dyeing effect, that is, the fastness, and the dyeing mechanisms are as follows. Take different forms. Among them, permanent hair dyes penetrate low molecular oxidation dyes into hair,
At the same time, it acts as an oxidizing agent and undergoes oxidative polymerization to form a polymeric pigment and deposit it in the inner layer (cortex) of the hair. It is not possible to go out and therefore the effect of the hair dye is permanent.

The permanent hair dye includes an oxidative hair dye, a vegetable hair dye, and a metal hair dye. Of these, oxidative hair dyes are the most widely used because they have a permanent effect compared to other types, and can be used to make the color tone lighter than the original hair because they have a bleaching effect. Have been. As described above, the oxidation hair dye takes a two-part form in which the oxidizing agent acts on the oxidizing dye to cause oxidative polymerization, and the first part contains the oxidizing dye and the second part contains the oxidizing agent. I do.

[0005] Among them, the second agent mainly contains hydrogen peroxide as an oxidizing agent. Since hydrogen peroxide is easily decomposed, a chelating agent, a pH adjuster and the like are blended as a stabilizer. The container for the oxidized hair dye for accommodating such a highly reactive oxidized hair dye second agent is required to have a capability of stably storing and holding the oxidized hair dye second agent.

In addition, a container for an oxidative hair dye for accommodating the second agent of the oxidative hair dye is required to have a gas barrier property capable of preventing the permeation and volatilization of the oxidant to the outside. Conventionally, high-density polyethylene resin bottles have been widely used. On the other hand, from the viewpoint of beauty, a permanent agent is used to wave hair.

The most important point in forming a permanent wave in hair is in the structure of the hair. Hair has a network structure in which polypeptide chains of keratin, which is a main component, are connected by various side chain bonds. As the component that most affects the formation of the permanent wave, the strongest disulfide bond (S
-S bond). Disulfide bonds are cleaved by reducing agents to cysteine, but oxidizing agents also generate new disulfide bonds. Therefore, in the technology for forming a permanent wave on hair, a reducing agent and an oxidizing agent, that is, a permanent agent containing these agents play a major role.

[0008] Perm agents are classified according to usage and main components, and there are various types, but most of perm agents currently used are composed of independent first and second agents. . The first agent cleaves a disulfide bond as the first stage of wave formation, and contains a reducing agent. In addition, purified water such as ion-exchanged water is used as a medium together with a reducing agent as a main agent, and an alkali agent, a reaction regulator and the like are further compounded. Among them, for example, ammonium carbonate is compounded.

The second agent is for a second step of forming a new disulfide bond and forming a wave,
Contains oxidizing agent. Bromic acid or hydrogen peroxide is used as the oxidizing agent. Since both the first and second permanent agents have high reactivity, a container for storing the permanent agent is required to have a capability of stably storing and holding the permanent agent. In addition, the first agent containing a reducing agent has a problem that it reacts with oxygen in the air and is deteriorated. Therefore, a high oxygen barrier property (gas barrier property) for suppressing permeation of oxygen is strongly required. On the other hand, the second agent containing the oxidizing agent is required to have a gas barrier property capable of preventing the oxidizing agent from permeating and volatilizing to the outside.

As a perm agent container satisfying such requirements, a container in which an aluminum layer is laminated on a resin layer is conventionally used.

[0011]

However, with respect to the former high-density polyethylene resin bottle used as an oxidative hair dye container for containing the second oxidative hair dye, the container is efficiently incinerated. To do so, it is necessary to treat at a relatively high temperature, which is inconvenient for incineration.

In the case of a container in which an aluminum layer used as a permanent agent container for accommodating the first and second agents of the permanent agent is laminated on a resin layer, for example, the laminated layer of aluminum has a permanent agent layer. There is a disadvantage that one agent causes corrosion, and it is inconvenient for incineration as in the former case of a high-density polyethylene resin bottle.

From the viewpoint of solving such inconvenience in the incineration process, for example, a paper pack container (hereinafter, may be simply referred to as a container) 1 shown in FIG. 2 may be used as a liquid container. The paper pack container 1 is generally formed by laminating, for example, a polyethylene resin layer 6 inside a paper layer 5 (see FIG. 4B), and is a cuboid standing type liquid storage container. It is. FIG.
The middle portion (seal portion) 2 extending in the upper left and right directions of the container 1 is bent to prevent a problem in aesthetics of the container 1 and in handling of the container 1, and on the side surface 1 a of the container 1. It is pasted. Further, an opening (not shown) for taking out an appropriate amount of cosmetic is provided at the upper end of the container 1, and the opening is covered with a cap 3.

However, when the paper pack container 1 contains cosmetics such as the first and second agents of the above-mentioned perm, the cosmetics are stably stored due to the deterioration of the resin layer 6 and the like. It is not always easy to hold. Also,
When the container 1 storing these cosmetics is placed in a high-temperature environment, for example, components such as ammonium carbonate in the cosmetics are thermally decomposed or gasified due to a decrease in solubility in the liquid, and therefore, As shown in FIG. 3, when the internal pressure of the container 1 increases and the container 1 expands and deforms, the ears 2 of the container 1 that has been bent and attached are peeled off, and further, the perspective view of FIG. As shown in FIG. 4 and a partial sectional view of FIG. 4B, the resin layer 6 near the heat seal portion 4 of the container 1 is formed.
However, there is a problem that the container 1 is torn by the pulling force accompanying the expansion of the container 1 and eventually the container 1 is ruptured. For example, when the container 1 is placed under the conditions of 40 ° C. and 75% RH, the ear 2 of the container 1 is peeled off after 3 to 7 days, and when the container 1 is placed under the temperature of 50 ° C., about 1%. After a lapse of days, the resin layer 6 is torn.

The present invention has been made in view of the above-mentioned problems, and it is possible to stably store and retain acidic or alkaline cosmetics, to secure good gas barrier properties, and to further improve the disposal process. An object of the present invention is to provide a cosmetic container that has few problems and does not cause deterioration of the storage function due to deformation of the container even when the internal pressure of the closed container increases due to generation of gas in a high temperature environment. And

[0016]

Further, since the innermost polyethylene layer is thickened, the tensile strength of the polyethylene layer is improved, and the synergistic effect with the paper layer prevents the polyethylene layer in the vicinity of the heat seal portion from being torn, further destructing the container. Nothing.

The above-mentioned cosmetics which can suitably exhibit the effects of the present invention include a first permanent agent containing a reducing agent as a main agent and ammonium carbonate as an alkaline agent, and an oxidizing agent as a main agent. And a second oxidative hair dye containing an oxidizing agent as a main agent.
