Description

[Detailed description of the invention] This invention allows the mixing of two liquids by transferring the liquid from one container to the other container containing the other liquid by simply screwing one container into the other. Do 2
Related to liquid mixing containers.

For example, when using a liquid for hair dyeing or hair styling such as permanent hair, two different types of liquids are mixed together. In this case, transferring the liquid from the opening of one container to the other via the opening not only causes the liquid to spill, but is also a troublesome task, so a separate container is prepared and an appropriate amount of the two liquids is Mixing may be considered, but in this case a separate container must be prepared, which is troublesome and inconvenient, especially since hair dyeing is often done at home. .

The present invention makes it possible to easily mix the two liquids without preparing a separate mixing container and without causing liquid spillage by applying a simple device to each container of the two liquids to be mixed. It is an object of the present invention to provide a reliable two-liquid mixing container which has a simple liquid-tight sealing structure, is reliable in sealing, is easy to mold, and is easy to break the seal.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 and 2 are first and second containers containing different seed liquids, respectively, and 3 is an intermediate cylindrical member that connects and holds these containers 1 and 2 together.

The first container 1 has a bellows-like elastic part 5 that expands and contracts vertically at the lower part of the body 4, and a thread 7 is formed on the outer periphery of the lower half of the neck part 6. A breakable thin sheet 8 such as aluminum foil is attached to the top surface to seal the inside liquid-tight.

The second container 2 has a body 9 whose inner diameter is larger than the outer diameter of the mouth and neck 6, and whose bottom opening at the lower end is liquid-tightly sealed with a breakable thin sheet 10 such as aluminum foil. Also, a mouth part 11 extending upwardly in a nozzle shape from the upper end of the body part 9 is provided, and a blade 12 is provided in the body part 9 from the inner periphery of the upper end to the inside of the mouth and neck part 6 and extending in the circumferential direction to near the lower end of the body part 9. Place an appropriate number of them vertically,
A thread 13 is provided on the outer periphery of the upper end of the body part 9, a locking protrusion 14 is provided on the outer circumference of the lower part of the body part 9, and an engaging protrusion 15 is provided on the outer circumference somewhat below the locking protrusion 14. As shown in FIG. 2a, a large number of circumferential engagement longitudinal stripes 16 are provided on the outer periphery below the protrusion 15. As shown in FIG.

The intermediate cylindrical member 3 is provided with a guiding peripheral wall 18 on the inner periphery of the intermediate cylinder that slides into contact with the outer peripheral surface of the upper half of the mouth and neck part 6 of the first container 1 via an inward flange 17, and on the inner periphery of the upper part of the intermediate cylinder member 3. An engagement groove 19 that engages with the engagement protrusion 15 of the container 2 is formed on the inner circumferential surface below the engagement groove 19, and a large number of engagement vertical grooves 20 that engage with each of the engagement longitudinal grooves 16 are formed on the inner circumferential surface below the engagement groove 19. In addition, screw grooves are provided on the inner periphery of the lower half of the lower part of the guide peripheral wall 18 to be screwed into the screw threads 7, and short cylindrical sealing pieces 22 connected by discrete pieces 21 from the lower end periphery are provided in series. There is. 23 is the sealing piece 2
The second knob is shown. A cap 24 has a protrusion 25 for sealing the upper opening of the mouth 11 at the center of the back surface of the top wall, and a threaded groove for screwing with the thread 13 on the inner periphery of the lower part of the peripheral wall.

In the above structure, the engagement groove on the inner periphery of the upper end of the intermediate cylinder member 3 is engaged with the engagement protrusion 15, and the engagement vertical groove 2 is engaged with the engagement protrusion 15.
0 to the engagement vertical strip 16 to fit and attach the upper half of the intermediate cylinder member 3 to the lower part of the second container 2, and in this state, the screw of the neck part 6 of the first container 1 is The strip 7 is screwed into the threaded groove of the intermediate cylindrical member 3, and is screwed onto the lower half of the intermediate cylindrical member 3 of the first container 1, and the first and second containers 1 and 2 are attached as shown in the figure. Connect and hold in a stacked state.

In the above-mentioned combined state, the cutting edge of the blade 12 in the second container 2 touches the sheet 8 of the first container 1.
As will be described later, the distance maintained against the top surface of the mouth and neck sealed by the sealing piece 22 is removed,
The intermediate cylinder member 3 is set to be shorter than the distance through which the intermediate cylinder member 3 can be screwed into the first container 1 .
From now on, the product will be transported and stored in this illustrated state.

Next, in order to mix the two liquids during use, pinch the knob 23 to break the broken piece 21 and peel off the sealing piece 22, then grip the first container 1 and rotate the intermediate cylinder member 3. It is only necessary to move the container and screw it toward the first container 1. Then, the second container 2 is integral with the intermediate cylindrical member 3, so the second container 2 moves downward together with the intermediate cylindrical member 3, and this movement first causes the sheet 10 of the second container 2 to move downward. The first container 1 is broken at the top of the mouth and neck, and then the sheet 8 of the first container 1 is broken by the blade 12, so that the liquid in the second container 2 falls into the first container 1. The two liquids are mixed. The extensible portion 5 is expanded by transferring this liquid. After this, the cap 24 can be removed to use the mixed liquid.

According to the present invention, two liquids can be mixed by simply screwing the intermediate cylinder member 3, so there is no need to prepare a special mixing container, and there is no need for troublesome injection operations. You can mix liquids without spilling them. Furthermore, since it is necessary to break and remove the sealing piece 22 when mixing the liquids, it is convenient because it is obvious at a glance whether the liquids have been mixed or not. Furthermore, when the two liquids are not mixed, the first container 1 is shrunk and has a low overall height, which is convenient for transportation, storage, and other handling.

Further, both the first container 1 and the second container 2 have sheets 8,
10, especially in the second container 2,
The blade 12 is vertically fixed in the container sealed with the sheet 10, and since there are no members that move relative to each other while maintaining a liquid-tight state in both containers, the dimensional accuracy of each container 1 and 2 is high. It can be made looser and the blade 12
Since the blade 12 is integrally molded and vertically installed on the second container 2, the blade 12 can be molded at the same time as the second container 2, and the molding is easy, the structure is simple, the assembly is easy, and the number of parts is small. Although it can be provided at a relatively low price, it maintains liquid tightness and is easy to break the sheet.
It also has various effects such as maintaining certainty.
