Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-agent mixing container in which two agents, such as a liquid, a gel, and a powder, can be separately stored in one container and mixed when used.

[0002]

2. Description of the Related Art Two kinds of liquids for styling hair such as hair dye or permanent, water and concentrated juice, two kinds of gel-like agents for preparing adhesives Various two-agent mixing containers have been proposed in which two agents are separately accommodated in two accommodation chambers and the two agents are mixed by communicating the two accommodation chambers immediately before use. However, such conventional containers inadvertently mix two agents due to shock or the like,
Due to the drawbacks such as leakage, few have been implemented. The present invention clarifies a two-agent mixing container that can solve the above problems.

[0003]

The two-component mixing container of the present invention comprises:
A container body (1) in which a body (10) is constricted and a mouth (12) is provided at the upper end and a thread (13) is formed in the mouth (12), and a constricted portion (11) of the container body (1). ) And a guide surface (22) having a substantially conical shape that extends in the vicinity of the mouth (12) and expands downward at the upper end.
2) A vertically elongated plug body (2) having a circumferential groove (21) on the lower outer periphery, and a cylindrical body screwed into the mouth (12) of the container body (1) and protruding in the center of the lower surface.
A synthetic resin cap (3) having an inward flange (34) fitted to the peripheral groove (21) of the plug (2) at the lower end of (33), and the plug (2) At least one of the container body (1) is made of synthetic resin, and the container body (1) is connected to the stopper (2).
It is divided into two chambers (14) and (15), the upper and the lower.

[0004]

[Function] For the filling of the two agents, the agent (2) is removed and the chamber (15) at the bottom of the container is filled with the one agent. Next, the stopper (2) is forced into the container constriction (11) to partition the upper and lower chambers (14) and (15) in a liquid-tight manner, and the upper chamber (14) is filled with another agent. The cap (3) is screwed onto the container mouth (12).

Immediately before the end of tightening of the cap (3), the flange (34) at the lower end of the tubular body (33) in the center of the cap hits the guide surface (22) at the upper end of the plug (2), and the flange (34) The guide surface (22) is elastically deformed and slides down. When the collar (34) corresponds to the circumferential groove (21) of the plug body (2), the collar (34) elastically returns and fits into the circumferential groove (21). Since at least one of the container body (1) and the plug body (2) is made of synthetic resin, when the plug body (2) is pushed into the container constriction (11), the resin is elastically deformed so that it is tight. And the upper and lower chambers (14) and (15) can be completely shut off. Therefore, the two agents separately stored in both chambers (14) and (15) are not mixed.

The stopper body (2) and the container constriction portion (11) are tightly fitted by the elastic deformation of the resin, and the cap (3) is used to prevent the stopper (2) from coming off. The plug (2) will not come off unless it is loosened. Also, the cap
(3) is tightly screwed into the mouth portion (12) of the container body (1) and never loosens unless a force for pulling out the stopper body (2) in the axial direction acts.

Therefore, the cap (3) is once tightened with a strong force, and the cylindrical groove (33) of the cap (3) and the peripheral groove (21) of the plug (2).
Even if a shock to the extent that the container is dropped on the floor is applied, the cap (3) and the stopper (2) synergistically act on each other to loosen the cap (3) and the cylindrical body (33). Can be securely prevented from coming out of the container, the two agents in the container are mixed, or the container mouth
The contents will not leak from between the (12) and the cap (3).

In use, when the cap (3) is rotated and loosened, the collar (34) of the cap cylinder (33) is fitted with the circumferential groove (21) of the plug (2).
The cap (3) is attached to the stopper (3
3) is lifted to open the container constriction portion (11), and one agent in the upper chamber and one agent in the lower container are mixed. Cap (3)
When the cap is loosened, pull-out resistance of the plug (2) acts, but the cap (3) is screwed into the container mouth (12), and the plug (2) is pulled out by the screw thrust generated when the cap is loosened. , Loosening the cap (3) does not require too much force.

EXAMPLE As shown in FIG. 2, a container body (1) is made of synthetic resin, a body (10) is confined and a mouth (12) is provided at an upper end, and a screw () is formed around the mouth (12). 13) is formed. The inner diameter of the constricted portion (11) of the container body (1) is smaller than the inner diameter of the mouth portion (12), and the plug body (2) is tightly fitted in the constricted portion (11).

The plug body (2) is made of synthetic resin and is formed as a hollow body having an open lower end and a closed upper end. The lower end of the stopper (2) gradually expands to form an annular contact piece (23) larger than the inner diameter of the constricted portion (11) of the container body (1) and smaller than the inner diameter of the container mouth (12). However, a peripheral wall (24) is provided so as to project inwardly downward from the corresponding piece (23). The outer diameter of the peripheral wall (24) is the container constriction (11)
The diameter is slightly larger than the inner diameter, and the lower end is gradually reduced in diameter. The upper end of the plug body (2) is formed with a guide surface (22) of a substantially conical shape whose lower part expands, and the guide surface is provided on the lower peripheral surface of the guide surface (22).
A circumferential groove (21) is formed continuously with (22).

As shown in FIG. 3, the cap (3) screwed into the container mouth (12) has a thread (32) formed on the inner surface of the outer peripheral wall (31). The cap (3) is provided with a cylindrical body (33) protruding downward, and the lower end of the cylindrical body (33) is engaged with the circumferential groove (21) of the plug body (2). ) Is projected. The peripheral wall (24) at the lower end of the stopper (2) is tightly fitted to the container constriction (11),
With the (3) completely closed, the collar (34) is attached to the circumferential groove (2
Determine the length of the cap cylinder (33) so that it fits in 1).

The entire cap (3) including the tubular body (33) is molded of synthetic resin, and the lower end of the tubular body (33) is elastically deformed and slides on the guide surface (22) of the plug body (2). The collar (34) engages with the circumferential groove (21). When the cap (3) is loosened, the collar (34) has a groove (21).
The hardness of the cap (3), particularly the lower end of the cylindrical body (33) is determined so that the plug (2) can be pulled out of the cap (3) while being engaged with. The cap (3) has an annular baffle wall inside the peripheral wall (31) with a gap corresponding to the thickness of the container mouth (12).
(35) is projected.

In order to fill the container with the two agents, first, the container (15) at the bottom of the container is filled with the one agent with the stopper (2) removed. Next, the lower end peripheral wall (24) of the stopper (2) is forcibly pushed into the container constriction (11), and the chamber (14) above the container is filled with another agent.
The cap (3) is screwed onto the container mouth (12).

Immediately before the tightening of the cap (3), the flange (34) at the lower end of the tubular body (33) at the center of the cap hits the guide surface (22) at the upper end of the plug (2), and the flange (34). Is elastically deformed, spreads and descends, and when it reaches the circumferential groove (21) of the plug body (2), the collar (34)
Elastically returns to fit in the circumferential groove (21). Cap in this state
(3) is the deadline.

Since the container body (1) and the plug body (2) are made of synthetic resin, when the plug body (2) is pushed into the constricted portion (11) of the container, the resin is elastically deformed to tightly close it. It can be fitted and the complete cutoff can be drawn. Therefore, the two agents separately stored in both chambers (14) and (15) are not mixed.

The stopper body (2) and the container constriction portion (11) are tightly fitted by the elastic deformation of the resin, and the cap (3) is used to prevent the cap (3) from coming off. The plug (2) will not come off unless it is loosened. Also, the cap
(3) is tightly screwed into the mouth portion (12) of the container body (1) and never loosens unless a force for pulling out the stopper body (2) in the axial direction acts.

Accordingly, once the cap (3) is tightened with a strong force, the cylindrical body (33) of the cap (3) and the circumferential groove (2
If 1) is engaged, even if a shock to the extent that the container is dropped on the floor is exerted, the synergistic effect of the cap (3) and the plug (2) causes the cap (3) to loosen and the cylinder ( The escape of 33) can be reliably prevented, the two agents in the container do not mix, and the contents do not leak from between the container mouth (12) and the cap (3).

In use, when the cap (3) is turned and loosened, the plug body (2) caught on the collar (34) of the cap cylinder (33).
Is pulled out, the container constriction (11) is opened, and the upper chamber (1
4) One agent mixes with one agent in the lower chamber (15). cap
When loosening (3), the pull-out resistance of the plug (2) acts,
The cap (3) is screwed into the container mouth (12), and the stopper (2) is pulled out by the screw thrust generated when the cap (3) is loosened. Therefore, the cap (3) does not need to have a strong force to be loosened.

When the two agents are put in the container and the cap (3) is tightened, the cylindrical body (33) of the cap (3) is elastically deformed to engage with the circumferential groove (21) of the plug (2). Although a strong force is required to bring the caps (3) together, the cap (3) at the time of shipping is tightened by an automatic machine, so even if a strong tightening force is required, there is no problem.

In carrying out the present invention, the container body (1) is not limited to the synthetic resin, and the same effect as above can be obtained even if it is formed of glass. The above description of the embodiments is for explaining the present invention, and should not be construed as limiting the invention described in the claims or limiting the scope. Further, the configuration of each part of the present invention is not limited to the above embodiment,
It goes without saying that various modifications can be made within the technical scope described in the claims.
