DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-component mixing container which can store two kinds of materials separately without mixing them, and can mix these two kinds of materials when used. About.

[0002]

2. Description of the Related Art For example, in performing hair dyeing, two kinds of liquids may be mixed and used. However, after the mixing, a chemical reaction occurs with the passage of time and the effect as a hair dye is weakened. Therefore, it is required that the two types of liquids are mixed immediately before use. Also, in consideration of the trouble such as the need to transfer for mixing, a container capable of mixing two kinds of liquids quickly and easily is desirable.

In order to satisfy such a demand, Japanese Utility Model Registration No. 2503369 discloses the following container. First, the entire container is divided into upper and lower portions, and the lower side is a cylindrical first container body, and the upper side is a cylindrical second container body. Above the first container body, there is provided a cylindrical first connection member fitted non-rotatably, while below the second container body, a cylindrical second connection member non-rotatably fitted. A connection member is provided. These first connection member and second connection member
It is fitted rotatably. Furthermore, the partition member partitions the space communicated by the first connection member and the second connection member. The lower part of the outer periphery of the partition member and the inner periphery of the first connection member are combined so as to be slidable only in the direction of the central axis of the cylinder. .

In a container having such a structure, when the first container body and / or the first connection member is fixed and the second container body is rotated, the second connection member is simultaneously rotated. Since the screwing between the second connection member and the partition member is released with the rotation of the second connection member, the partition member moves inside the first connection member toward the lower part of the cylindrical center axis. Finally, when the screwing is released, the partition member falls into the first container body by its own weight. As a result, the inside of the first container and the inside of the second container are communicated.

[0005] If two different materials are previously sealed in each of the first container body and the second container body, the two kinds of materials can be mixed and used by performing the above operation.

[0006]

However, this type of conventional container has a complicated structure and a large number of parts, and it is not easy to reduce the manufacturing cost. Furthermore, since it has a structural feature that the partition member is dropped into the first container body before mixing and then two kinds of materials are mixed, after the communication between the first container body and the second container body, The partition member floated inside the first container body, and there was a fear that the mixing of the two types of materials was hindered by the partition member.

[0007] The present invention has been made in view of these problems, and can sufficiently mix two types of materials.
Another object of the present invention is to provide a two-component mixing container having a simple structure.

A two-agent mixing container capable of mixing and discharging two agents in each container when used, wherein an opening convex portion is formed at an upper portion of the first container, and the convex portion is formed at a bottom portion of the second container. Can be inserted, a concave portion having a closed surface for closing the opening of the convex portion is formed, and the opening of the convex portion is provided between the convex portion and the concave portion with respect to the closed surface. A coupling means for coupling the convex portion and the concave portion so as to be separable is formed, and when the opening of the convex portion is separated from the closing surface, the first agent in the first container is filled in the second container. One or more holes are preliminarily penetrated into the side surface of the concave portion so as to move to the position shown in FIG.

When storing the first agent and the second agent in the container according to the present invention, first, the first agent is put into the first container, and the convex portion on the upper portion of the first container and the concave portion on the bottom portion of the second container are removed. And the opening of the projection is brought into contact with the closing surface. As a result, the opening of the projection is closed, and the first agent is confined inside the first container. In addition, one or more holes previously formed in the side surface of the concave portion are closed by the side surface of the convex portion. Next, the second agent is placed in the second container, and the second container is sealed by any known method. In this way, it is possible to store the two materials separately without mixing.

When mixing the first agent and the second agent, the container of the present invention is turned upside down without loosening the connection between the convex portion and the concave portion. If the connection between the convex portion and the concave portion is slightly loosened in this state, the first container and the second container communicate with each other, and the first agent moves into the second container. In other words, by loosening the connection, the closing of the opening of the convex portion and the closing of the hole on the side surface of the concave portion are released. Then, the first agent can move inside the second container 6 by passing through these. Since there is nothing obstructing the first agent to move into the second container, the effect of reducing the amount remaining in the first container is exhibited.

After almost all of the first agent has moved into the second container, the opening of the projection is again brought into contact with the closed surface. As a result, the opening of the protrusion and one or more holes in the side surface of the recess will be closed again. Therefore, even if this container is shaken to mix the first agent and the second agent, the mixed agent does not flow back into the first container. Since the mixture does not flow back into the first container, the mixture can be easily discharged by applying pressure to the second container.

[0012] The invention according to claim 2 is the invention according to claim 1.
An agent mixing container, wherein the coupling means is constituted by screw portions that can be screwed together. According to the second aspect of the present invention, since the first container and the second container are connected to each other by a screw portion that can be screwed to each other, the two containers can be gradually separated from each other. Therefore, when this container is used, there is no fear that the convex portion will be completely pulled out of the concave portion so much. In addition, mischief of the infant can be prevented beforehand.

[0013] The invention according to claim 3 provides the invention according to claim 1.
An agent mixing container, wherein the coupling means is constituted by concave and convex portions which can be fitted to each other. According to the third aspect of the present invention, since the first container and the second container are connected by the concave and convex portions that can be fitted to each other, the first container and the second container can be communicated with each other with a simpler operation. It is possible.
