BACKGROUND OF THE INVENTION The present invention relates to a two-part mixing container.

[0002]

[Prior art]

[Problem to be solved by the invention]
The lower part of the intermediate cylindrical member is screwed into the mouth of the first container, and the lower end is sealed to the upper part of the intermediate cylindrical member with a stopper whose lower end is locked to a seat of the cylindrical member. The second container is screwed into the second container, the second container is screwed away from the intermediate cylindrical member, and the plug is detached and removed from the lower opening downward to remove the liquid in the second container from the first container. The present applicant has already proposed a container configured to perform two-liquid mixing by dropping and transferring into a container (Japanese Utility Model Publication No. 63-603).
Issue 2). This container can be mixed without the need for preparing a special mixing container and without the need for a troublesome pouring operation, simply by screwing out the second container, and the number of components is small, and each component can be used. Since the final product can be assembled simply by screwing and fitting, it has various effects such as a simple configuration and convenience without tools or labor for assembly.

[0003] However, when filling this container,
First, the first container is filled with the first liquid, and then the intermediate cylinder member is screwed into the mouth and neck of the first container. The ridge is fully screwed into the thread groove to be mounted on the intermediate tubular member. That is, the locking ridge protruding from the outer peripheral lower end of the peripheral wall of the plug is forcibly pushed into the inner peripheral wall of the seat and penetrates therethrough, and is locked on the lower peripheral surface of the inner peripheral wall such that it cannot move upward. The outer peripheral surface of the lower half of the peripheral wall is in a free state with a small gap from the inner peripheral surface of the inner peripheral wall of the seat. In this state, the second container is filled with the liquid, and then a cap is attached to the upper opening of the container to seal the opening.

Therefore, it is difficult to forcibly push in unless the locking projection of the plug is slightly projected from the inner surface of the lower end of the inner peripheral wall of the seat. On the other hand, if the projection is slightly projected, the first container is screwed up. In such a case, there is a possibility that the plug may rise together with the first container and may not come off.

[0005] The present invention proposes an excellent two-liquid mixing container which has solved the above-mentioned disadvantages of the prior art.

[0006]

In order to solve the above-mentioned problems, the container of the present invention raises the mouth and neck portion 12 from a squeezable cylindrical body, and forms a squeezable and cylindrical upper end opening in the center of the body. The upper wall 3a, which closes the opening of the upper end surface of the partition wall 6, is liquid-tight to the upper edge of the partition wall 6 and can be detached by the pressure deformation of the partition wall 6. The inner cap 3 fitted to the partition wall 6 is provided so as to partition the inside of the partition 6 as a first liquid storage section 17.
The inside of the body of the container other than the above was configured as the second liquid storage unit 18.

[0007]

When the mark 16 of the container body 2 is squeezed from the state shown in FIG. 1, the internal partition 6 is also squeezed and deformed at the same time, whereby the inner cap 3 is removed and the inside of the first liquid storage part 17 and the second liquid The inside of the storage section 18 communicates and the two liquids are mixed. At this time, if the inner cap 3 is formed of a rigid material, the inner cap 3 can be more easily removed when the partition 6 is deformed. Next, after the container is shaken well to stir the mixture, the nozzle cap 4 is removed and the body of the container is squeezed to discharge the mixture.
