DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pouch container for a permanent agent for filling a permanent agent containing a reducing agent.

[0002]

2. Description of the Related Art From the viewpoint of cosmetics, waving hair, and in particular, a technique of forming a so-called permanent wave, is a technical field that is being developed every day with the development of drugs and the like used therein. 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. And as a component which most affects the formation of a permanent wave, it has the strongest disulfide bond (SS bond) among various side chain bonds. Disulfide bonds are cleaved by reducing agents to cysteine, but oxidizing agents also generate new disulfide bonds.

[0003] A permanent wave is formed through this reduction and oxidation. 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. Perm agents are classified according to usage and main components, and there are various types, but most of the perm agents currently used are composed of independent first and second agents.

[0004] The first agent, which cleaves disulfide bonds as the first stage of wave formation, contains a reducing agent. The second agent creates a new disulfide bond,
For the second stage of forming the wave, it contains an oxidizing agent. As described above, these permanent agents are intended to react with the hair and act thereon, and are required to have a high acting force. However, such acting force can naturally act on the external environment other than the hair. is there.

That is, both the first and second permanent agents have high reactivity. In particular, the first agent containing a reducing agent is:
There is a problem that it is degraded by reacting with oxygen in the air. In order to avoid such problems, the pouch container for the permanent agent is required to have the ability to stably store and hold the permanent agent, in addition to the lightness and robustness in consideration of its handling,
In particular, a pouch container filled with a first agent containing a reducing agent is strongly required to have a high oxygen barrier property for suppressing permeation of oxygen through the vessel wall.

[0006] As a pouch container for the first agent of the perm agent which satisfies such requirements, a pouch container in which an aluminum layer is laminated on a resin layer has been conventionally selected and used.

[0007]

However, for example, in a conventional pouch container for a permanent agent in which a polyethylene resin or the like is used as the innermost layer and an aluminum laminate layer is provided as an intermediate layer, the aluminum laminate layer is made of a permanent agent. There was a disadvantage that corrosion was caused by one agent.

The present invention has been made in view of the above problems, and provides a pouch container for a permanent agent which has a high oxygen barrier property and does not corrode even when touching a permanent agent containing a reducing agent. It is an issue.

[0009]

A pouch container for a permanent agent according to the present invention is a pouch container for filling a permanent agent containing a reducing agent, has a multilayer structure, and is welded to the innermost layer. A first resin layer (for heat sealing);
At least one in which silicon dioxide is deposited outside the resin layer of
The second resin layer of the layer is provided.

The second resin layer on which silicon dioxide is deposited may be any layer other than the innermost layer. In addition, from the viewpoint of the effect of the present invention, it is preferable that silicon dioxide is deposited on both surfaces of the second resin layer, but from the viewpoint of economy, it is sufficient to deposit silicon dioxide on only one surface. In this case, it is preferable to deposit silicon dioxide on the surface facing the inside of the container. Although the resin material of the second resin layer is not particularly limited, a polyethylene terephthalate resin is preferably used. Although the resin material of the first resin layer is not particularly limited, a polyethylene resin or a polypropylene resin is preferably used. The type of the permanent agent containing the reducing agent is not particularly limited, but is preferably applied to a cream type.

Here, the pouch container is, for example,
One that is made by folding one sheet in half or using two sheets to heat seal the periphery to form a closed structure. Not only a bag-shaped one but also a cuboid-shaped one (standing type) ) Is also included. This allows
A pouch container for a permanent agent that has high oxygen barrier properties and does not corrode even when touched with a permanent agent containing a reducing agent (one permanent agent) can be obtained.

[0012] In the pouch container for a permanent agent according to the present invention, the reducing agent is selected from the group consisting of thioglycolate, cysteine, N-acetylcysteine, glyceryl monothioglycolate and cysteamine salt. It is characterized by comprising at least one component.
Thereby, when a permanent agent containing a reducing agent which is very effective for forming a permanent wave in hair is filled, a high oxygen barrier property is exhibited and a permanent agent containing a reducing agent (one permanent agent) Thus, a pouch container for a permanent agent that does not corrode even when touched can be obtained.

[0013]

As shown in (a), for example, the container body 12 and the cap 14 are used, and the first agent of the perm agent is
, And sealed with a cap 14. The container body 12 is formed by heat sealing a sheet having a multilayer structure. As shown in FIG. 1 (b), a resin layer (first resin layer) 16 made of, for example, a polyethylene resin for welding to form a sheet-like material into a bag-like shape is disposed as an innermost layer. Silicon dioxide is deposited on one surface of a resin layer 18a made of polyethylene terephthalate resin to form a silicon dioxide deposited layer 18b, and a resin layer (silicon dioxide) having the surface on which the silicon dioxide deposited layer 18b is formed facing inward is formed. Is deposited on the outside of the resin layer 16 for welding. Further, in the present embodiment, the nylon resin layer 2 is provided between the innermost resin layer 16 and the resin layer 18 via the adhesive layers 20a and 20b.
Further, a polyethylene terephthalate resin layer 24 is disposed outside the resin layer 18 made of polyethylene terephthalate resin on which silicon dioxide is deposited via an adhesive layer 20c. By arranging the nylon resin layer 22, the container becomes robust, and by arranging the polyethylene terephthalate resin layer 24 as the outermost layer, printing can be suitably performed on the surface of the polyethylene terephthalate resin layer 24.
