Caps for storing solutes

technical field

The utility model relates to the technical field of beverage packaging, in particular to a bottle cap capable of storing solute.

Background technique

In order to properly deal with the relationship between solute and solvent in solution beverage products, people have used many methods, one of which is to separate the solute and solvent in the product packaging before the beverage is purchased or ready to be drunk. Placed in a plastic bottle, the solute is placed in a separate container, which is fixed on the bottle cap. When in use, the solute is put into the bottle by rotating or pressing down on the solute container and mixed with a solvent to form a solution for use. Therefore, various technologies are mainly designed around the bottle cap, and for different specific uses or design emphases, different structures appear: for example, in the patent application of our country, the technical solutions provided for the following application numbers: 201120047446.1, 200520035580.4, 200420025070.4, 99204493.6, 98104679.7, 03208533.8, 200720116477.1, 200710144623.6, 200510125293.7, 201320417936.5, etc.

The above technical solutions each have their own characteristics, and further optimizing the structural design of the bottle cap with solute storage function is a technical problem to be solved urgently by those skilled in the art.
