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 capable of containing two types of components in an isolated state and mixing them when used.

[0002]

2. Description of the Related Art Conventionally, various cosmetics, hair stylings, and the like have been developed and marketed, and among them, there is one in which two different liquids are mixed and used. Such cosmetics and the like contain the above two types of liquids in one container, and when the container is kept stationary, separate the container into upper and lower layers due to a difference in specific gravity. Stirring is performed sufficiently. However, some of such cosmetics lose their effectiveness due to a chemical change or the like if two kinds of liquids are mixed in advance. Therefore, when not in use, the two types of liquids are stored in separate containers in a separated state, and the two liquids are mixed and used when used. In addition, some cosmetics use a mixture of a liquid cosmetic and a powdery cosmetic. However, similar to the above, the disadvantage is that the efficacy is lost if premixed. In addition, those mixed in advance show a muddy appearance and have a bad aesthetic appearance and usability. Therefore, as described above, the two types of components are housed in separate containers, and the two components are mixed and used at the time of use.

[0003]

However, as described above, if the two types of components are contained in separate containers, the components in each container must be transferred to another container when used.
Alternatively, since the components in one container must be transferred into one container, the operation becomes complicated and the usability is poor. Also, when transferring and mixing the two components as described above,
Inconveniences such as scattering of components such as powder or liquid occur,
In some cases, your fingers get dirty. Furthermore, since two components are stored in two containers, there is a disadvantage that it is inconvenient to carry.

[0004] In order to accommodate two different components in a single container in an isolated state, there is one disclosed in Japanese Utility Model Publication No. 57-52020. This is, as shown in FIG.
The inner container 31 whose lower end opening is closed by the aluminum film 32 is attached to the inner peripheral surface of the inner container 31a, whereby the liquid 34 is accommodated in the inner container 31, and the body 30b of the container body 30 is attached.
A different kind of liquid 35 can be accommodated therein.
At the time of use, as shown in FIG.
3 is removed from the neck 30a.
3a, the aluminum film 32 of the inner container 31 is broken, whereby the liquid 34 in the inner container 31 is dropped and mixed with the liquid 35. Then, as shown in FIG. After being attached to the neck 30a, the tip 33a of the cap 33 is cut and the mixed liquid is taken out from the cut opening. However, in this case, the aluminum film 32 of the inner container 31 must be broken at the tip of the cap 33 after removing the cap 33 at the time of use, and this operation is troublesome.

[0005] The present invention has been made in view of such circumstances, and it is possible to accommodate two different components in a single container in an isolated state, and to prevent the two components from mixing until use. Another object of the present invention is to provide a two-component mixing container which can mix two components with a simple operation when used.

[0006]

In order to achieve the above object, a two-component mixing container according to the present invention comprises a first container having a bottomed cylindrical shape .
Container, a second container in the shape of a canopy, and a holding part at the upper end
A cylindrical fixing cap protruding in the
For example, sealed top opening of the first container with a thin film portion breakable, and capped the second container to the upper end opening to seal the top opening, the second in the state Open bottom of container
Hold down the flange formed on the mouth with the above holding part from above
And attach the fixing cap to the first container
Only, above one of the two containers, the spout that is freely stopper mounting and plug member provided inward reversible variable either of the ceiling portion of the bottom or second container of the first container The flexible body is formed of a flexible body, and a part of the flexible body is provided with a convex portion that breaks the thin film portion when the flexible body is turned inward.

[0007]

That is, in the two-component mixing container of the present invention, the upper end opening of the bottomed cylindrical first container is sealed with a breakable thin film portion, and the upper end opening is provided with the topped cylindrical second container. And the upper end opening is sealed. Therefore, the inside of the first container and the inside of the second container are separated by the thin film portion, and different components are contained in the first and second containers, respectively, so that different two components are contained in one container. Can be accommodated in an isolated state. In addition, either the bottom of the first container or the ceiling of the second container is formed of a flexible body that can be turned inward, and a part of this flexible body is used when the flexible body is turned inward. A convex portion for breaking the thin film portion is provided. Therefore, in use, the thin film portion can be broken at the convex portion by pressing the flexible body inward and inverting it. as a result,
One component contained in the second container falls from the broken portion of the thin film portion, and mixes with the other components contained in the first container. In this way, by pressing either the bottom of the first container or the ceiling of the second container, the components contained in each container can be mixed, and the operation is simplified. In addition, since the thin film portion can be broken simply by pressing the convex portion on a part of the flexible member, it is not necessary to press the entire flexible member with a large force. In addition to pressing the convex portion, the small force can be concentrated on the distal end portion of the convex portion to reliably break the thin film portion. In addition, when the bottom of the first container is formed in a convex shape with a flexible body, when the container is placed on a display shelf or the like, the bottom bends and becomes a substantially horizontal surface, so that a stable state is obtained. Can be arranged in large numbers.

Next, the present invention will be described in detail based on embodiments.
