Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention is intended to store two liquids which are stored separately during storage and which are mixed when used, and which are tightly separated from each other, and open both liquid storage spaces when used. The present invention relates to a two-liquid storage container capable of mixing in a container.

[0002]

2. Description of the Related Art There is a two-liquid storage container configured to store and hold two types of liquids in a separated state at the time of storage, and to mix and discharge the same at a predetermined ratio at the time of use. As this two-liquid storage container, there is a container disclosed in Japanese Utility Model Publication No. 62-38912.

[0003] The prior art disclosed in Japanese Utility Model Publication No. 62-38912 discloses a container body having a thread provided on the outer periphery of a neck portion, and an engaging cylinder fitted into the neck portion of the container body. A connection cylinder in which a lower cylinder portion is screwed into the neck portion of the container main body to erect the cylinder portion, and a sliding cylinder portion is suspended from the inner surface of the cylinder portion through the engagement cylinder portion; It consists of a lower lid fitted to the lower end of the sliding cylinder and a cap fitted to the upper end of the connecting cylinder. When the connecting cylinder is loosened relative to the container main body, it comes into contact with the lower end of the engaging cylinder and is prevented from rising. The lower lid is configured so that a part of the lower lid is located below the engaging cylinder so that the lower lid can be detached from the sliding cylinder. The two-liquid container is vertically suspended from the inside of the connecting cylinder by screwing the connecting cylinder in the loosening direction with respect to the container main body from a state in which the two kinds of liquids are integrally stored in a tightly separated state. Along with the sliding cylinder portion, the lower lid fitted to the lower end of the sliding cylinder portion also tries to screw up, but since the outer peripheral portion of the bottom plate is in contact with the lower end of the engaging cylinder body and is blocked,
The lower lid cannot be lifted, so the lower lid is removed from the sliding cylinder,
It falls below the container main body, and at the same time, the inside of the connecting cylinder and the inside of the container main body communicate with each other, and the two kinds of liquids contained in each of them are mixed.

In the prior art having the above-described structure and operation, the two kinds of liquids can be integrally stored and held in a state of being tightly separated, and the operation of loosening the connecting cylinder with respect to the container body can be performed. Since only two kinds of liquids can be mixed with each other, excellent effects such as an extremely easy and safe mixing operation are exhibited.

However, Japanese Utility Model Publication No. 62-38 mentioned above.
In the prior art disclosed in Japanese Patent Publication No. 912, a part of the connecting cylinder has a double cylinder wall structure, and a female screw structure is provided in the double cylinder wall structure. However, since the structure of the connecting cylinder is relatively complicated, it is necessary to mold the connecting cylinder with a synthetic resin material having good moldability. However, depending on the content resistance required for the connecting cylinder, a synthetic resin having good moldability is required. There is a problem that the material cannot be used in some cases.

In addition, since the main body of the container and the connecting cylinder are directly screw-connected to each other, the molding material of the main body of the container and the connecting cylinder exhibits stable mechanical strength in addition to high content resistance. Therefore, there is a problem that the regulation of the molding material of the container main body and the connecting cylinder is also strengthened.

The container body and the engagement cylinder are assembled by screwing and assembling a container body filled with a certain amount of liquid into a connection cylinder having the engagement cylinder assembled with the lower lid. By the screwing and assembling operation of the container body to the connecting cylinder, the engaging cylindrical body assembled in the connecting cylinder in a fixed posture is engaged with the opening of the container main body.

As described above, since the assembling operation of the engagement cylinder with the container main body requires the screwing and assembling operation of the container main body filled with the liquid and the connecting cylinder, it is sufficient for the assembling work. In addition, since the engagement assembly of the engagement cylinder with the container main body is achieved using the screwing force between the container main body and the connection cylinder, the container main body and the connection cylinder are extremely strongly screwed. It is necessary to assemble them, which causes inconvenient problems such as an excessively strong strength of the assembling of the container main body and the connecting cylinder, which makes it difficult to achieve the opening operation, and an irregular deformation of the threads. is there.

Further, in the above-mentioned prior art, since the barrel portion of the container is located at the lower position, in order to extract the mixed two liquids, the container is located at the lower position of the entire container. Has to be squeezed and deformed, which makes it difficult to perform the liquid pouring operation.

Therefore, the applicant of the present invention has previously constructed the lower container and the upper container, which are the main parts that directly store and hold the liquid, so as to be independent of the coupling of the two containers and the sealing action between the two containers. A two-liquid container has been proposed for the purpose of reducing the restrictions on the molded synthetic resin material of both containers and simplifying the assembling operation of the entire container (Japanese Utility Model Application No. 1-1).
32609).

[0011]

However, in the two-liquid storage container filed earlier, the lid that defines the lower container and the upper container in a liquid-tight manner engages with the inner cylinder (undercut fitting). Therefore, when mixing the contents stored separately in the lower container and the upper container, a large rotating torque is required to remove the lid from the inner cylinder, and there is a problem that the usability is not good. .

In order to reduce this torque,
Although it is conceivable to reduce the fitting force between the lid and the inner cylinder,
If the fitting force between the lid and the inner cylinder is reduced, the airtightness of the lower container and the upper container will be poor, and the contents separated and stored in the lower container and the upper container will be mixed during use. Reliability decreases. Further, in the case of the undercut fitting, there has been a problem that the fitting force is reduced with time, which also lowers the reliability of the two-liquid storage container.

The present invention has been made in view of the above points, and an object of the present invention is to provide a two-liquid storage container which can remove a lid from an inner cylinder with a small rotating torque and can improve reliability. And

[0014]

In order to solve the above-mentioned problems, in the present invention, a mouthpiece is provided upright at the upper end of a bottomed tubular body, and a lower portion in which the first contents are stored. The condition and the second
An upper container having a discharge port through which the first and second contents are ejected and having a mouthpiece protruding from an opening formed at the lower end; An inner connecting member fixed to the lower container by having a connecting cylinder provided with a connecting strip that protrudes, and a neck tube piece formed at a lower end of the connecting tube being liquid-tightly and immovably assembled to the mouthpiece; And a double-cylinder structure of an inner cylinder and an outer cylinder disposed outside the inner cylinder. A first screw is formed on the upper part of the inner cylinder, and the outer cylinder is attached to the upper body. An outer connecting member having a fixing mechanism for fixing, and a supporting tube extending downward from the outer tube and being rotatably attached to the inner connecting member so as to be unable to come out of the inner connecting member; And an inner cylinder of the outer connecting body having an engaging member that slidably engages the connecting member in a vertical direction. A lid that closes the mouthpiece in a state where the second screw is screwed with the first screw formed, and the first screw and the second screw are screwed together; And a two-liquid storage container.

[0015]

The lid is attached to the external connector by screwing the first screw and the second screw into the two-liquid container. Accordingly, the coupling force between the lid and the external connector is strong, and the lid does not loosen over time from the external connector, and the reliability of the two-liquid container can be improved.

Further, when mixing the first contents stored in the lower container and the second contents stored in the upper container, the external connector is rotated to remove the lid from the external connector. At this time, the lid is attached to the external connector by screwing the first screw and the second screw, so that the lid can be removed from the external connector with a small rotating torque, and Performance can be improved.

Further, the engaging ridge formed on the lid is engaged with the connecting ridge formed on the inner connecting body, so that the rotating force of the lid is transmitted to the lid, and the lid is smoothly removed. It can be performed.
