BACKGROUND OF THE INVENTION
The present invention relates to a two-component mixed dropping container in which two types of storage agents, such as liquids and powders, stored separately inside are mixed at the time of initial use, and dropped and used using a dropper function. It is.
[0002]
[Prior art]
As a conventional technique of a two-component mixing container that is used by mixing two agents at the time of use, the upper end is opened into the mouth and neck of the container body that has a shoulder under the mouth and neck and stores any liquid. A dissimilar liquid storage cylinder whose bottom is closed with a thin film is fitted, and the cap is fitted to the outer periphery of the mouth neck so that the cap can be lowered, and the cap is closed so that it can be cut open from the top surface of the top wall. A tubular portion is projected upward, communicated with the tubular portion from the lower surface of the top wall, and is fitted to the inner circumferential wall of the storage tube so as to be watertight and depressible, and continuously connected to a part of the tubular body. There is a structure in which a piercing bar longer than the body is suspended and a cap lowering prevention ring that can be cut and removed between the lower end surface of the cap peripheral wall and the container shoulder is interposed (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 2000-85828
In addition, in a dripping container using a dropper mechanism, the elastic button part that swells in a dome shape and elastically deforms is formed thinly integrally with the cylindrical wall constituent part of the container, thereby reducing the number of parts and the manufacturing cost of the container Is being reduced.
[0005]
[Problems to be solved by the invention]
However, in the above-described prior art, in order to mix the two agents, the cap is pushed down against the container body, and the cylinder is inserted into the dissimilar liquid storage cylinder tightly assembled to the mouth and neck of the container body. As a result, the pressure in the container body is increased by at least the volume of the cylindrical body fitted in the different type liquid storage cylinder, and due to this increased internal pressure, the liquid mixture is ejected or the sealing performance of the sealing function section is reduced. There was a risk of inconvenience.
[0006]
In addition, if the elastic button part, which is a dropper function part, is thinly formed integrally with the cylindrical wall constituting part of the container, the thickness of the elastic button part should be made sufficiently thin to dripping the content liquid. Although it is easy to perform the dispensing operation, when it is actually used, the return speed to the original shape of the elastic button part that has been inverted and inverted is slow, and it takes time for continuous dispensing operation. There was dissatisfaction that the deformed elastic button part could not return to its original shape and could not be poured out.
[0007]
Therefore, the present invention was devised to solve the above-described problems in the prior art, and in a two-component mixing dripping container using a dropper function, an increase in the internal pressure of the container is prevented at the time of two-component mixing. The technical problem is to increase the elasticity of the elastic button part, which is a functional part, so that after mixing the two agents, it prevents improper ejection of the liquid mixture and deterioration of the sealing function, and the liquid mixture is stable and continuous. It aims at obtaining the dripping extraction handling which was done.
[0008]
[Means for Solving the Problems]
Among the present invention for solving the above technical problem, the means of the invention according to claim 1 is provided with a mouth part at the upper end of the body part and a dropping cylinder piece that forms a dropping hole at the lower end, Having a main body for storing one agent;
