[0001]

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.

If the locking ridge of the plug does not fit perfectly with the inner surface of the lower end of the inner peripheral wall of the seat, if the container is accidentally knocked down or the container is tilted after mixing the two liquids, First
The liquid in the container may leak from this portion to the outside through the gap between the second container body and the intermediate cylindrical member.
Further, in order to eliminate such inconvenience, the dimensional accuracy of each member in this portion must be made extremely high, and the production becomes complicated, and equipment accompanying the production is required.

[0006] Further, if the outer periphery of the lower end of the peripheral wall of the second container and the inner surface of the intermediate cylinder portion above the seat are fitted in a liquid-tight and rotatable manner, it seems that such a disadvantage can be solved. obtained in the structure as the first container, for not be necessary to use a split mold for molding, a good sealing property caused slight ridges by a gap between the split mold on the outer peripheral surface thereof with a mouth Is
No.

The present invention proposes an excellent two-liquid mixing container which solves the above-mentioned disadvantages of the prior art.

[0008]

In order to solve the above-mentioned problems, the container according to the present invention has a first container body 2 having a mouth-neck portion 2c which is longer than a body portion 2a, and upper and lower portions from upper and lower ends of a body portion 3a. A second container body 3 having protruding mouth and neck portions 3b and 3c, and a lower end edge of a fitting tube portion 4a having an inner peripheral surface fitted to the outer periphery of the lower mouth and neck portion 3c via an inward flange 4b. The connection assisting member 4 having the seal cylinder 4c having the upper end protruding into the second container body 3a is mounted on the lower mouth and neck 3c of the second container 3 in a liquid-tight and non-rotatable manner. , The fitting cylinder 4a
The inner peripheral upper end of the cylindrical peripheral wall 5a is screwed to the lower part of the outer periphery so that the peripheral wall 5a can be screwed up, and a ring band-shaped spacer portion 5d for preventing the peripheral wall 5a from being screwed up is extended on the upper end surface of the peripheral wall 5a so as to be cut off. And the outer periphery of the first container body neck portion 2c is fitted to the inner surface of the seal tube portion 4c in a liquid-tight and slidable manner.
Non-rotatable and axially slidable on the outer periphery of the body 2a at the lower part of the inner periphery
Non fitted so to connect the two vessel bodies 2 and 3, with is capable fitting the pressing withdrawal <br/> from liquid-tightly down outer peripheral edge to the sealing tubular portion 4c upper, tubular sealing portion 4c An inner cap 6 for closing the upper end opening is provided to partition the inside of each container body, and when the connecting member 5 from which the spacer portion 5d is removed is screwed up, the inner cap 6 is moved to the first container body neck and neck portion 2c. The upper end was configured to be able to be depressed and released.

[0009]

After removing the spacer portion 5d from the state shown in FIG. 1, when the connecting member 5 is screwed up, the first
The container body 2 is rotated upward, and the inner cap 6 is pressed and removed at the upper end of the mouth and neck 2c, and the insides of the first and second container bodies 2 and 3 communicate with each other to mix the two liquids.

[0010]
