Description

[Detailed description of the invention] The present invention is a two-liquid mixing container that mixes the two liquids by pouring the liquid from one container into the other container by simply screwing one container onto the other. Regarding.

As is well known, liquids used in hair styling such as hair dyeing or permanent styling are used by mixing two different types of liquids. In this case, transferring the liquid from the opening of one container to the other via the opening not only causes spillage but also is a troublesome task, so a separate container is prepared and an appropriate amount of 2.
Mixing liquids may be considered, but in any case it is troublesome and inconvenient, especially since hair dyeing is often done at home.

The present invention is a two-liquid mixing container that can easily mix two liquids without preparing a separate mixing container and without causing liquid spills by applying a simple device to each container of the two liquids to be mixed. The purpose is to provide.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In each figure, 1 and 2 are first and second containers containing different types of liquids, respectively. The first container 1 has a fitting protrusion 4 on the top of the outer surface of the mouth and neck 3, a screw thread 5 on the lower outer surface, and a tray-shaped stopper 6 to seal the opening. It is the composition. The stopper 6 is tightly sealed to obtain a sufficient liquid-tight effect, but it is inserted in such a way that if a certain amount of force is applied from the top, it will come off and fall downward.

Next, the second container 2 has a threaded groove 7 formed on the inner peripheral surface of the lower part of the peripheral wall to be threadedly engaged with the thread 5 of the first container 1,
Further, an opening is formed in the center of the bottom wall 8 in the middle of the peripheral wall above the screw groove 7, a middle plug 9 is sealed into the opening from below, and a nozzle cap 10 is fitted and fitted in the upper part. It is. The inner stopper 9 has a downward double wall that can be snugly fitted into the opening of the first container 1 on the outer edge of the base plate 11, and a fitting groove 13 on the inner peripheral surface of the outer peripheral wall 12. An upwardly facing peripheral wall 14 is provided in the central part to serve as a plug body, and the plug body 14
Through holes 1 are formed here and there in the circumferential direction of the outer substrate 11.
This is the structure that opened 5. The inner circumferential wall 16 of the downward double wall hangs down longer than the outer circumferential wall 12. The plug body 14 of the inner plug 9 is slightly tightly sealed in the opening of the bottom wall 8 so as to be sufficiently liquid-tight, but it is inserted in such a way that it can be unplugged when a certain amount of force is applied. Further, both the containers 1 and 2 are molded and manufactured from soft plastic or the like.

In the above configuration, in order to mix the two liquids, the second
The lower spiral groove 7 of the first container 2 is connected to the neck part 3 of the first container 1.
By screwing into the thread 5 of the container, the containers are mounted so as to be stacked in two layers. As this screwing progresses,
First, the lower surface of the internal circumferential wall 16 of the downward double wall of the inner stopper 9 comes into contact with the top surface of the circumferential wall of the stopper 6 of the first container 1, but as the screwing continues without worrying, as shown in FIG. The stopper 6 is pushed by the inner circumferential wall 16 and falls downward inside the container 1, while the downward double wall of the inner stopper 9
The inner stopper 9 is firmly fitted to the opening of the first container 1 because the protrusion 4 fits into the fitting groove 13 of the first container 1 . However, in this state, the two liquids are not mixed yet.

Next, in the above state, when the second container 2 is screwed back to move it upwards, the inner stopper 9 is firmly fitted into the opening of the first container 1, so the second container 2 is removed. moves upward as shown by the broken line while leaving the inner stopper 9, and as a result, the inner stopper 9 is removed from the opening in the bottom wall 8, and the liquid in the second container 2 is released from the through hole 15. It falls into the first container 1 below, and the two liquids are mixed. After this, the spout 10a at the tip of the nozzle cap 10 of the second container 2 may be cut with scissors or the like before use.

As described above, in the present invention, the opening of the first container 1 is sealed with the stopper 6 that can be opened downward, while the second container
The container 2 is provided at its lower part with a threaded part 7 that threads into the mouth and neck part of the first container 1, and a bottom wall 8 above the threaded part 7.
An inner stopper 9, which can be unplugged only downward, is sealed from below into the opening of
and the downwardly facing double walls 12 and 16 which push the stopper 6 of the first container 1 downward and which are clamped into the opening of the first container are provided, so that the second container 2 is simply opened.
2 by screwing it into the first container 1 and screwing it back.
It can perform liquid mixing, and is extremely simple and convenient to handle. That is, according to the present invention, there is no need to prepare a special mixing container, there is no need for troublesome pouring operations, and moreover, it is possible to mix the liquid without spilling even a single drop.

Furthermore, since liquid mixing is performed with both containers 1 and 2 sealed, there is no risk of spilling the contents even if the containers are tipped over, and both containers 1 and 2 can be handled individually, with the screw It is convenient because it can be combined and handled as a single unit, and since only five parts are required, the structure is simplified, and the spouting part is nozzle-shaped, making it easy to pour.
