PROBLEM TO BE SOLVED: To pour surely a mixed liquid without separating two containers from each other, and enable separate filling of the containers without having restrictions in a production line by a method wherein an opening/closing valve is constructed so that it can be opened or closed by screwing two combined cylindrical containers. SOLUTION: The first cylindrical body 2 equipped with an annular valve seat 3 constituting one side of an opening/closing valve structure 3 is screwed onto a container 1 for the first liquid, and the second cylindrical body 4 in a capped cylinder-shape equipped with a cylindrical valve body 3b constituting the other side of the opening/closing valve structure 3 is screwed onto the first cylindrical body 2 so that it can move in screwing. In the case of mixing of two kinds of liquids, the second cylindrical body 4 is moved in screwing against the first cylindrical body 2 and the opening/closing valve structure 3 is put under the state of opening and the second liquid is made to flow into the container 1 from a housing part 5. Then, a cap 4d is opened and mixed liquid can be poured out from a spout 4c through the housing part 5. Furthermore, each of the containers can be filled separately without being turned over at a production line.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-liquid mixing container mainly for separating and storing chemicals and the like that need to be mixed immediately before use, and for easily mixing them when necessary.

[0002]

2. Description of the Related Art As a structure of a conventional two-liquid mixing container, for example, the structure disclosed in Japanese Utility Model Laid-Open No. 58-145868 is known. This includes a container for the first liquid, a lid screwed to the first screw portion of the opening of the container, and a lid screwed to the lid so as to open and close with respect to the opening provided therein. It is a very simple mixing container that consists of a two-liquid container. When mixing the two liquids, the second liquid container is screwed with respect to the lid to open the opening, and the second liquid is transferred to the first liquid container in the first liquid container. Is mixed.

[0003]

However, when pouring out the mixed liquid from this container, the container for the second liquid is removed from the lid and discharged from the opening or the second liquid is discharged. It is necessary to remove the lid together with the container from the opening of the container for the first liquid. Therefore, there is a trouble of such removal (first problem).

Further, since it is necessary to connect the containers with each other via a lid in a state where the respective containers are filled with the first liquid and the second liquid, the container for the second liquid is filled with the second liquid. First, the lid is screwed into the container for the second liquid, the opening of the lid is closed, and then the container for the second liquid is turned upside down and filled with the first liquid. It is necessary to screw the lid to the container for the first liquid.

[0005] As described above, it is easy to manually perform an operation of inverting a container filled with liquid, however, during the operation of filling the liquid on a production line, such an operation of the container is performed. To perform the reversal mechanically, a rather complicated device must be prepared and incorporated into the production line (second problem).

[0006] Thereafter, the mixture can be poured out without separating the whole container, for example, see Japanese Utility Model Application Laid-Open No. 2-1058.
No. 82, a two-component mixing container having a coupling structure has been proposed. Here, one end (valve element) of the on-off valve structure is fitted into the opening of the container for the first liquid, and the container forms the other (annular valve seat) of the on-off valve structure in the container. The connector is screwed together, a container for the second liquid having an open bottom is fitted and mounted on the connector, and a cap is screwed on the top of the container. When the connection body is screwed into the container for the first liquid, one of the on-off valve structures (the valve body) is fitted to the other (the valve seat) to close the on-off valve structure. It is.

In this two-liquid mixing container, after filling the first liquid in the container for the first liquid, the connecting body is screwed in and the on-off valve structure is closed, and then the container for the second liquid is filled. Is fitted to the connection body, and in this state, the second liquid is filled from the top, and the cap can be fitted thereon.
It is a solution to the above problem.

However, in order to mix the two components in a container,
By screwing the connecting body with respect to the first liquid container and loosening the screw, the valve body is separated from the valve seat and the open / close valve structure is opened. In order to separate the body from the valve seat, it is necessary to fix the valve body to the first liquid container with a certain degree of certainty that the body will not come off when the valve body is first fitted.

This is because if the valve element is movable, the valve element moves with the valve seat when the connecting member is screwed, and the opening / closing valve structure remains closed. There is a fear that two-liquid mixing may not be possible, and the cap is removed while both containers are connected, and the liquid mixed in the first liquid container is mixed with the on-off valve structure and the second liquid container. Through
This is because, at the time of pouring, the valve body is pressed against the valve seat by being pushed by the mixed liquid, and the opening / closing valve structure is closed, which may hinder the pouring of the mixed liquid.

Further, the disadvantage of this two-liquid mixing container is that
The second liquid is filled in the liquid container in advance, and one of the containers cannot be connected via the connecting member without inverting one container. This is inconvenient when the design for connecting the two containers in advance needs to be made in the equipment of the production line by storing the liquid separately for each container in advance on the production line. (Third problem).

Because, as described above, the valve body is fixed to the first liquid container side, even if the connecting body is connected to the second liquid container in advance, the opening / closing valve structure is not required. This is because, in the open state, before connecting the containers, it is impossible to store the liquid separately in each container in advance and connect them without inverting one of the containers.

The present invention has been made on the basis of the above circumstances, and has as its object the purpose of being able to reliably discharge a mixed solution without separating both containers, while having a relatively simple configuration. (First problem), and without turning over the container (second problem) and without being restricted on the production line (third problem),
An object of the present invention is to provide a two-liquid mixing container capable of filling two liquids.

[0013]

Therefore, in the present invention,
A first liquid container having a first screw portion formed in an opening; a second screw portion screwed to the first screw portion of the container; and one of an on-off valve structure opposed to the opening portion , A fourth screw portion screwably screwed to a third screw portion formed in the first cylindrical member, and a second tube forming the other of the on-off valve structure. And a fourth screw portion is screwed with respect to a third screw portion to open and close the on-off valve structure. A storage part, and at least the second cylindrical body has
A spout for discharging a mixture of the two liquids and a cap for opening and closing the spout are integrally formed.

In this case, the spout can be used also for injecting the second liquid into the storage section. As a preferred embodiment of the present invention, one of the on-off valve structures is an annular valve seat facing the center of the opening,
The other may be a column-shaped valve body formed in the second cylindrical body so as to fit in a liquid-tight manner with the valve seat.

Therefore, in such a configuration, the first and second cylindrical bodies have the storage portion for the second liquid, the opening / closing valve structure and the spout, so that the container can be separated. Can be performed without performing the process, and the filling of the liquid in each container on the production line can be performed in the container connecting step, or in advance, the liquid can be individually supplied to each container. It can also be realized by connecting the containers after filling the container. That is, the two-liquid mixing container can exhibit the advantage of being versatile with respect to filling equipment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. In addition, FIGS.
FIGS. 8 and 9 show a first embodiment of the present invention, and FIGS. 8 and 9 show a second embodiment.

(First Embodiment) A two-liquid mixing container shown here has a first screw portion (male screw) 1 on the outer periphery of an opening 1a.
b for forming a first liquid (cylindrical shape with a bottom) and a second screw portion (female screw) 2 screwed to the screw portion 1b of the container 1
a first tubular body 2 having a bottom (an annular valve seat) 3a of the on-off valve structure 3 facing the opening 1a and the tubular body 2;
A fourth screw portion (female screw) 4a screwably screwed into a third screw portion (male screw) 2b formed in the second portion and the second (cylindrical valve element) 3b of the on-off valve structure 3 It is composed of a cylindrical body 4 (headed cylindrical shape).

In this embodiment, these are all made of synthetic resin. The on-off valve structure 3 is opened and closed by screwing a fourth screw portion 4a with respect to a third screw portion 2b. , A storage section 5 for the second liquid. In this case, in order to ensure the liquid tightness of the storage portion 5, an annular portion 4b that is in close contact with the upper inner peripheral surface of the tubular body 2 is formed inside the tubular body 4.

The cylindrical body 4 is integrally formed with at least a pouring opening 4c for pouring out a mixed liquid of two liquids and a cap 4d for opening and closing the same. In this case, the spout can also be used for injecting the second liquid into the storage section. In this embodiment, the cap 4d
Is a so-called three-point hinge 4e (the hinge portion is A) formed on the cylindrical body 4 by utilizing the elasticity of the synthetic resin.
(Indicated by point, point B, and point C), and an opening / closing plug 4f that is detachably fitted to the spout 4c is formed inside the cap 4d.

In such a configuration of the two-liquid mixing container, two different filling methods are possible to individually store the two liquids on the production line. In the first filling method, as shown in FIG. 3, the container for the first liquid is filled with the first liquid, and thereafter, the container shown in FIG.
As shown in FIG. 5, the two tubular bodies 2 and 4 with the on-off valve structure 3 closed are screwed into first and second screwing means as shown in FIG.
Are connected to the container 1 with the screw portions 1b and 2a), the cap 4d is opened, and the second liquid is supplied from the spout 4c to the storage portion 5
Is filled.

In the second filling method, as shown in FIG. 3, while filling the first liquid in the container for the first liquid, the cap 4d is opened, and as shown in FIG. Injection port 4c is provided in storage portion 5 of both cylindrical bodies 2, 4 with structure 3 closed.
, And then the container 1 is filled with the second liquid by screwing means (first and second screw portions 1b and 2a).
To join.

In such a filling method, the on-off valve structure 3 is placed in the closed state without turning over the two cylindrical bodies 2 and 4 constituting the container for the second liquid, and the second liquid is discharged from the spout 4c. Since two liquids can be filled, the liquid is filled in each container on the production line in the container connecting step, or the containers are connected after each container is individually filled with the liquid in advance. It can also be realized in a form. That is, the two-liquid mixing container can exhibit wide versatility with respect to filling equipment.

Further, at the time of mixing the two liquids, the second cylindrical body 4 is screwed with respect to the first cylindrical body 2 (third and fourth screw portions 2b and 4a), as shown in FIG. As shown, the on-off valve structure 3 is opened (the valve body 3b is removed from the valve seat 3a),
The second liquid is caused to flow into the container 1 from the storage section 5 to achieve two-liquid mixing. Further, the mixed liquid can be poured out from the spout 4c via the storage section 5 as needed. In particular, in this case, since the spout 4c is configured to be small, the mixed liquid can be gradually poured out by a required amount.

FIG. 7 shows a modification of the structure of the cylindrical bodies 2 and 4. Here, the third screw portion 2 b of the cylindrical body 2 is a female screw, and the screw portion of the cylindrical body 4 is formed. 4a is a male screw.
Further, the inner wall of the storage unit 5 includes the inner wall of the tubular body 4 and the storage unit 5.
Formed inside the cylindrical body 2 in order to ensure the liquid tightness of the
And an annular portion 2c closely contacting the inner wall of the tubular body 4. Other configurations are the same as those of the embodiment shown in FIGS. 1 to 6, and the description thereof is omitted.

(Second Embodiment) In the embodiment shown in FIGS. 8 and 9, unlike the first embodiment,
An annular portion 4b formed on the inner side of the cylinder and closely contacting the inner peripheral surface of the tubular body 2 has a cylindrical shape extended to near the bottom of the tubular body 2, and the opening / closing plug 4f is poured. It is fitted in the mouth 4c in a liquid-tight manner. Other configurations are the same as those of the embodiment shown in FIGS. 1 to 6, and the description thereof is omitted.

In such a configuration, in addition to the above-described two filling methods, a filling method for filling the second liquid by inverting the container for the second liquid constituted by the cylindrical bodies 2 and 4 ( This is mainly done manually, but can also be used. That is,
As shown in FIG. 9, the tubular body 4 is placed upside down in advance,
The liquid is filled into the storage part 5 formed by the annular part 4b, and then the tubular body 2 is screwed to the tubular body 4 to close the on-off valve structure. Then, as shown in FIG. 8, the above-described cylindrical body 2 is screwed to the container 1 for the first liquid separately filled with the first liquid to join the two containers. Since the liquid mixing and pouring are the same as in the first embodiment,
The description is omitted.

The unique advantage of this configuration is that when the liquid is manually filled, at least the second liquid can be filled in the storage section 5 without using a small spout. It is easy to do. After the filling of the second liquid, the temporary cap is fitted to the cylindrical body 4 in a liquid-tight manner, and then the temporary cap is removed and screwed into the cylindrical body 2 as described above. , Can also be used.
