Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a two-liquid mixing container.

[0002]

[Prior Art] [Problems to be solved by the device]

 As a two-liquid mixing container, the lower part of the intermediate tubular member was screwed into the mouth of the first container, and the lower end was attached to the upper part of the intermediate tubular member and the lower end was attached to the seat of this tubular member. The second container with the mouth closed is screwed on, and the second container is screwed back from the intermediate tubular member to detach the stopper from the lower mouth downward and the second container is closed. The applicant has already proposed a container configured so that the liquid in the container falls into the first container and is mixed with the two liquids (Act No. Sho 63-6032). This container can be mixed simply by unscrewing the second container, without preparing a special mixing container, and without the need for a troublesome pouring operation, and has a simple structure and is a tool for assembly. It has various effects such as convenience without requiring time and effort.

However, when filling the liquid in this container, first, the first container is filled with the first liquid, and then the intermediate tubular member is screwed and attached to the mouth and neck of the first container, and then the stopper is attached to the lower mouth. The second container, which has been fitted and closed, is mounted on the intermediate tubular member by fully screwing the thread of the second container into the thread groove. That is, the locking ridges projecting from the outer peripheral lower end of the entire peripheral wall by the mounting are forcibly pushed into the inner peripheral wall of the seat and pierce through the inner peripheral wall of the seat, and are locked immovably upward on the lower peripheral surface of the inner peripheral wall. The outer peripheral surface of the lower half portion of the peripheral wall is in a free state with a slight 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 after that, a cap is attached to the mouth of the upper part of the container to seal the mouth.

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

If the locking projections of the stopper do not engage exactly with the inner surface of the lower end of the inner peripheral wall of the seat, when the container is accidentally tilted or the container is tilted after mixing the two liquids, The liquid in the first container may leak from this portion to the outside through the gap between the second container body and the intermediate tubular member. Further, in order to eliminate such an inconvenience, the dimensional accuracy of each member in this portion must be made extremely high, which complicates the manufacturing and necessitates equipments accordingly.

Further, it seems that such an inconvenience can be solved by fitting the outer periphery of the lower end of the second container peripheral wall and the inner surface of the intermediate cylinder portion above the seat so as to be liquid-tight and rotatable. With a structure like the first container with a mouth, it cannot be done without using a split mold, so a slight ridge is created on the outer peripheral surface due to the gap between the split molds, and a good seal is obtained. I can not get sex.

The present invention proposes an excellent two-liquid mixing container that overcomes the above-mentioned drawbacks of the conventional technology.

Thus, the rod portion 4d of the first inner cap 4 is pushed down, and the pressing portion 6e of the connection assisting member 6 pushes up the seal cylinder portion 5c of the second inner cap 5.

[0009]

[Action]

 When the first container body 2 is screwed up with respect to the connecting member 7 from the state shown in FIG. 1, the seal cylinder portion 7d of the connecting member 7 pushes down the rod-shaped portion 4d of the first inner cap 4 and the first inner cap 4 The thin ruptured portion 4e is cut, and the first inner cap portion below the ruptured portion is dropped into the first container body 2. At this time, the outer surface of the seal cylinder portion 7d of the connecting member 7 slides down on the inner surface of the seal cylinder portion 6c of the auxiliary connecting member 6 to maintain liquid tightness with the outside. On the other hand, the pressing portion 6e of the connection assisting member 6 pushes up the seal tubular portion 5c of the second inner cap 5 to cut up the thin-wall breaking portion 5d of the second inner cap 5, and the second inner portion inside the breaking portion is cut. The cap portion is pushed upward, and as a result, the insides of the first container body 2 and the second container body 3 are connected, and the two liquids are mixed.
