Description of the Related Art For example, as shown in Japanese Patent Application Laid-Open No. 11-278554, a pair of aerosols for storing different kinds of liquids, which penetrate a top wall that closes an upper surface of a can and urge the liquid ejecting stem upward to stand up. The can and the aerosol cans, a binding member for bringing the body portions into contact with each other and binding them together, and the first peripheral wall hanging down from the outer periphery of the first top plate to the upper outer surface of both aerosol cans are fitted, and from the outer periphery of the first top plate. A second top plate that opens the front and rear wall portions in the middle in the left-right direction to erect the second peripheral wall and closes the upper end opening surface of the second peripheral wall is placed on the upper end surface of the second peripheral wall and protrudes rearward; A second thin hinge is provided in the left-right direction of the front portion of the second top plate, and separation lines are formed on both left and right inner sides of the second peripheral wall from both ends of the second thin hinge to the rear end of the second top plate, and a pressing plate is provided. And a first top plate portion corresponding to the stem standing position. A horizontal cylindrical portion protruding forward from the upper end of the base cylindrical portion, which is fitted and raised at the lower end portion to the outer surface of the upper end portion of the stem, through the inside of the front wall opening portion of the second peripheral wall. A nozzle member integrally connected by an elastic piece with the front end approaching in a V-shape as viewed from the front upper part, and both stems can be lowered via the nozzle member by pushing down the rear end portion of the pressing plate. Formed aerosol-type two-part mixing containers are known.

[0003]

As shown in the above-mentioned known example, in the aerosol-type two-liquid mixing container, unlike a conventional aerosol can that jets only one kind of liquid, a pair of liquid jets is used. Since it is necessary to push down the stem at the same time, the cap-shaped member is fitted to the upper outer surface of the aerosol can. The material of this cap-shaped member is a synthetic resin material, while the aerosol can is made of metal,
Therefore, it is preferable to separate and discharge them. However, since the cap-shaped member is fitted to the aerosol can, it is difficult to separate and discharge them.

According to the first aspect of the present invention, the connecting member fitted to the two aerosol cans and the cover member fitted to the connecting member are easily separated, so that the aerosol can and the cover member can be separated. It is intended to facilitate separation and discharge.
