Abstract

PROBLEM TO BE SOLVED: To provide a tube container at a low cost, capable of sufficiently discharging gas even in the case of storing chemical preparations from which gas is evolved, moreover having no possibility of leakage of the chemical preparations, and unnecessary to strictly control the wall thickness of a tube. SOLUTION: The tube container 1 has a lower tube 5 made of an aluminum, with which a lower part of a tube main body 3 made of a high-density polyethylene is sheathed, and by stamping circular portions 15 of the lower tube 5, the lower tube 5 is partly fixed to the lower part of the tube main body 3. The lower ends of both the tubes are crushed flat together to be formed into a seamed flat part, and it is designed so that an oxidation hair dye 9 stored in the tube main body 3 does not leak from below. By this method, even in the case where gas is evolved from the oxidation hair dye 9, it is discharged from the terminal end of the flat part or from a portion between the tube main body 3 and the lower tube 5. Since the tube main body 3 itself is unnecessary to discharge gas, its wall thickness may optionally be made thick to the extent wherein it does not become hardly squeezable. Since the tube container 1 has a small number of component parts, it can be formed at a low cost.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube container, and more particularly, to a tube container for containing a creamy or liquid drug that generates gas with the lapse of time.

[0002]

2. Description of the Related Art Heretofore, as a tube container for containing this kind of drug, a device has been devised so that the tube container does not expand or rupture with the generation of gas. As such a tube container, a double tube container whose inside is made of a synthetic resin such as polyethylene and the outside is made of aluminum, an aluminum tube container whose inside is coated with a resin, a polyethylene tube container, and the like are known.

[0003]

However, each of the above-mentioned prior arts has a drawback. For example, a double tube container has no problem in discharging gas, but has a problem in that it is difficult to maintain an aesthetic appearance because it is made of aluminum and it is difficult to maintain aesthetic appearance during transportation because it is made of aluminum. . In addition, it is expensive because of the large number of parts.

[0004] Further, the aluminum tube container has a problem that when a pinhole is made in aluminum, corrosion occurs from the pinhole. Further, in the case of a polyethylene tube container, there is a problem that it is difficult to control the thickness of the tube. That is, if the tube is too thin, the moisture and oil content of the drug will escape, and if the tube is too thick, the gas will not escape.

The present invention has been made in view of the above problems,
The purpose of the present invention is to provide a low-cost tube container that can sufficiently discharge gas even when a gas-generating drug is stored and that does not need to worry about leakage of the drug and strictly control the thickness of the tube. And

[0006]

Means for Solving the Problems and Effects of the Invention The present invention according to claim 1, which has been made to solve the above-mentioned problems, comprises a synthetic resin tube main body, and a tube main body provided at one end of the tube main body. In a tube container provided with an opening for discharging an object to the outside and a flat portion formed by crushing at least the other end of the tube main body, a lower tube which is an aluminum tube at the other end of the tube main body And the two parts are partially fixed, and the flat part is formed by crushing the other end at least flat together with the lower tube.

[0007] According to such a tube container, even if gas is generated from the contents, the gas is discharged from the end of the flat portion or the unfixed portion between the tube body and the lower tube. There is no need to worry about the tube body swelling or bursting. Further, since the tube body itself does not need a gas discharging function, it can be made thicker so as not to be difficult to squeeze, and the thickness can be easily controlled. The tube container has a smaller number of parts than the double tube container, and can be configured at low cost.

The flat portion not only crushes the other end flatly with the lower tube, but also wraps it around,
It may be configured to be held by a clip-shaped member or partially adhered. As a material of the tube main body, as described in claim 2, high-density polyethylene, medium-density polyethylene, low-density polyethylene, linear low-density polyethylene, saponified ethylene-vinyl acetate copolymer, polyacrylonitrile, polyethylene Terephthalate, polypropylene, polyester, polyvinyl chloride,
One synthetic resin selected from nylon or a synthetic resin obtained by mixing two or more of these resins may be used.
Moreover, you may manufacture by laminating these synthetic resins. That is, two or more different synthetic resins are mixed with a synthetic resin obtained by laminating another synthetic resin on one synthetic resin or a synthetic resin obtained by mixing two or more synthetic resins. One kind of synthetic resin may be laminated on a laminated synthetic resin or a synthetic resin obtained by mixing two or more kinds of synthetic resins.

[0009] Among these, as in the present invention as set forth in claim 3, the tube for contacting the contents with one synthetic resin selected from high-density polyethylene, medium-density polyethylene, and low-density polyethylene. It is preferable in terms of liquid properties to use it for the layer of the main body (when the tube main body is composed of only one layer, it indicates the entire tube main body).

According to a fourth aspect of the present invention, there is provided the tube container according to any one of the first to third aspects, wherein the content is a gas generating agent. Hydrogen peroxide can be exemplified as such a drug. When such contents are stored, the effect as the tube container of the present invention, which achieves both easy gas release and contents retention, can be sufficiently exhibited. Although not contrary to the present invention, contents that do not generate gas may of course be stored in the tube container.

The lower tube 5 is fixed to the tube main body 3 by embossing the lower tube 5 from above. As a result, gas can be discharged from between the adjacent circular portions 15.

According to such a tube container 1, even if gas is generated from the oxidative hair dye 9, the end of the flat portion 7 as shown by the arrow A in FIG. Since the gas is discharged from between the tube body 3 and the lower tube 5, the tube body 3 does not have to be swelled or burst. Further, since the tube body 3 itself does not need a gas discharging function, the tube body 3 may be thick enough not to be difficult to squeeze. Since the tube container 1 has a small number of parts as described above, it can be configured at a low cost.

As described above, the tube container 1 has been described as one embodiment to which the present invention is applied. However, the present invention is not limited to this embodiment and can be implemented in various modes. For example, in the tube container 1, the tube main body 3 is made of high-density polyethylene.
