Description

[Detailed description of the invention] [Field of industrial application] The present invention provides two chambers each having an extrusion port in one container, and stores two types of containers that are mixed and used in the two chambers. It is a container that can accommodate two types of items that are filled and mixed together, and that after filling the container with the stored items through the open bottom opening of the container, the opening is crushed and welded to open the bottom. This invention relates to a synthetic resin tube container that forms a seal.

[Conventional technology]

There are many cosmetics that are mixed with other cosmetics before use. These cosmetics were individually stored in a single container, and when used, they were measured and taken out into a special container, where they were mixed and consumed.
If cosmetics that are constantly mixed and used are stored and maintained in completely separate containers, each cosmetic will be handled separately, which may result in one being lost or the cosmetics being stolen from the individual containers. There are complaints that it is troublesome to take out the cosmetics, and storing each cosmetic in separate containers naturally means that the number of containers used increases, which increases the cost of the containers. I am dissatisfied. Therefore,
Two chambers with respective extrusion ports are provided in one container, and two types of items to be mixed and used are filled in the two chambers, and two types of items to be mixed and used are stored in one container. Various synthetic resin tube containers have been proposed.

According to this type, two storage chambers are formed in parallel in one tube container, so
In order to push out the stored items, the pressing force can be applied equally to the two storage chambers, thereby making it possible to push out the stored items from both storage chambers at a desired ratio with a single pressing operation, and This means that items that are mixed and used all the time can be stored and held together.

For this type of container, the bottom seal of the container is formed before filling the contents, and the contents are filled from the extrusion port, and the contents are filled from the open bottom opening of the container (storage chamber). After that, the opening is crushed and welded to form a bottom seal.

Ease of filling is naturally better in the latter because of the size of the filling opening, and such a tube container is shown in FIG.

That is, as shown in FIG.
The inside of the body part 1, which is the main body part of the tube container, is divided into left and right parts by a compartment 2 that is integrated with the body part 1, and this divided compartment is divided into a head which is tightly welded and fixed to the upper end of the body part 1. It opens into an extrusion port 5 formed in the spout tube 4 of the section 3, and further welds and seals the lower end of the body section 1 in a flattened state to form a bottom seal 6.

[The problem that the idea aims to solve]

In the conventional art, the diameter of the body 1 is defined by the compartment 2, and the compartment 2 has the same width all the way to its lower end.

On the other hand, each half-circumference width of the body 1 forming the two left and right chambers is naturally set larger than the width of the compartment 2, but this difference cannot be converged by the bottom seal 6. Another problem is that the bottom seal 6 has to be a stepped seal (three layers and four layers), which is unfavorable in terms of seal reliability.

The present invention was devised in view of the problems of the conventional technology, and its purpose is to develop a synthetic material that can form a seal without any steps when forming a bottom seal for the opening of a storage chamber. The present invention aims to provide a tube container made of resin.

[Means to solve the problem]

In order to achieve the above object, the synthetic resin tube container of the present invention has two storage chambers each having an extrusion port in one container, and two types of plastic tubes that are mixed and used in the two storage chambers. Two types of items to be mixed and used can be stored in one container by filling the contents of the two storage chambers, and after filling the contents from the bottom openings of the two storage chambers in the open state, In synthetic resin tube containers that are crushed and welded to form a bottom seal, the barrel tube that forms the container body is integrated with the spout tube with extrusion ports on both sides of the partition wall that hangs down in the center. At the same time, the two tube tubes are inserted into the body tube and integrally connected to the lower end of the partition wall and the half periphery of the spout tube, respectively, and the bottom seal is attached to the body tube and the lower end opening of the tube tube. Both are crushed and welded together.

[Effect]

The part of the tube inside the body cylinder connected to the partition wall of the spout tube is not restricted as a container diameter regulating material, so when crushing to form a bottom seal, the bottom opening has an even thickness. It is possible to ensure that the bottom seal of the opening of the storage chamber does not have a stepped seal by being crushed.

In addition, each tube is in charge of storing and holding the contents, and the body is in charge of the outer shell mechanism as a tube container. You can choose the resin material.

〔Example〕

Hereinafter, one embodiment of the tube container of the present invention will be described with reference to FIG.

The spout tube 7 has a partition wall 8 hanging down in the center, and extrusion ports 9 are provided on both sides of the partition wall 8.

A barrel tube 10 forming a container body is integrally connected to the spout tube 7 by welding or the like.

Two tubes 11, 11 forming a storage chamber
are inserted into the body tube 10, and are integrally connected to the lower end of the partition wall 8 and the half circumference of the spout tube 7 by welding or the like.

The bottom seal 12 is attached to the body tube 10 and the tube tube 1.
This is done by crushing together with 1 and 11. This product is assembled and molded in the order shown in FIG. 3, for example.

The tube tubes 11, 11 formed into a semi-cylindrical shape as shown in FIG. 3a are combined into a cylindrical shape, and as shown in FIG. Assemble and mold as shown in Figure 3c. Once the container body is formed in this manner, the spout tube 7 having the structure shown in FIG. 2 is welded and fixed to the upper end of the body.

Once the tube container is formed in this way, each tube tube 1 is
After injecting and filling the contents to be stored into 1 and 11,
Insert the bottom opening of the tube container into both tubes 1.
1 and 11 are flattened from adjacent directions and tightly welded and sealed to form a bottom seal 12.

[Effect of idea]

Since the tube container according to the present invention has the above-described structure, it exhibits the following effects.

Since the bottom seal of the opening of the storage chamber is reliably a laminated seal of uniform thickness, the reliability of the seal is ensured.
Further, since the storage chamber forming material and the container body forming material are constructed as separate bodies, the optimum materials can be selected and used for each, which is advantageous in terms of design.
