I have. This type of two-liquid mixing container is suitable for single use or short-term use. In addition, 2
It is known that, when two liquids contained in two containers are used in a container, the two liquids meet the spout through each passage according to the amount used for one use, mix at the spout, and pour out. . This type of two-liquid mixing container is suitable for multiple use or long-term use.

Among the above two types, as a two-liquid mixing container in which two liquids are separated and stored by a partition wall, the first liquid is stored in an upper container made of a sheet material such as aluminum whose bottom plate can be broken. In some cases, a lower container containing the second liquid is provided below the upper container and integrated, and in addition, a cap with a knife attached downward is screwed into the upper container. Then, at the time of use, the knife is lowered by turning the cap to break the bottom plate of the upper container, the first liquid is allowed to flow down to the lower container and mixed with the second liquid, and then the mixed liquid is passed through the broken bottom plate to the upper part. It is to be discharged from the spout of the container to the outside. Also, pull out the attached stopper at the time of use, then push both containers into the stroke corresponding to the stopper coming off, the inner stopper incorporated in both container joints is released by pushing the stroke, and the two liquids are removed from both containers. Also known are two-liquid mixing containers that mix and pour in.
