  By the way, this type of container is a vertically long container in which a sub-container is arranged on the main container, and since the pump mechanism is additionally incorporated in this, the container tends to be tall. The increase in size is inevitable.

  In addition, in order to add the contents in the sub-chamber toward the contents in the main chamber, it is necessary to perform an accurate alignment operation for matching the openings provided in the respective chambers. Even if it can be done, it may not be possible to remove all of the auxiliary components (the opening has a certain size, so when the powder is used as the content, the content remains).

  Furthermore, when the container is held in an inverted posture during the distribution stage of the product, the contents (particularly powder) stored in the sub chamber may enter into the gap between the constituent members and be fixed. There was a problem that it was difficult to add the contents in the sub chamber toward the contents in the main chamber. In particular, when a pump having an outside air suction hole for releasing the negative pressure in the container is attached to the side wall of the cylinder, the contents (powder) block the hole and the outside air is introduced into the container. There was a possibility of disappearing.

  An object of the present invention is to provide a convenient two-agent that can be made compact by simply storing a pump mechanism and a subchamber containing auxiliary components in a container to make the container compact, and only by rotating operation. Proposed mixing vessel.
