2. Description of the Related Art Conventionally, there are preparations and the like which react with each other by mixing with other substances at the time of use, and can be used for a certain purpose. Usually, when mixed, the initial state of mixing and reacting with each other in advance cannot be maintained, for example, the reaction progresses and deteriorates with the passage of time.

[0003] For example, there is a hair dye of a type in which an oxidizing dye is mixed with an oxidizing agent such as a hydrogen peroxide solution which produces a pigment at the time of use. This hair dye is widely used because it has excellent advantages such as obtaining a natural color tone.However, at the time of storage, the oxidation dye and the oxidant are stored in separate containers, and these are mixed at the time of use. Was reacting.

[Problems to be solved by the present invention] However, storing these separately requires the work of opening and closing each container and the work of extracting a certain amount of each preparation, which is troublesome at the time of use. It was pointed out that handling was troublesome.

[0005] In addition, if the mixing amount of one agent and two agents depends on the estimated amount during mixing, one of the preparations will be extracted too much without extracting them in an appropriate amount. There was a risk of wasting. Alternatively, there is a problem that only one of the preparations is consumed quickly and the other is wasted.

The present invention has been made in view of the above circumstances, and provides a two-liquid mixing container which can store two agents to be mixed together and can extract and mix them simultaneously in one operation. With the goal.
