BOTTLE CAP WITH A STORAGE CHAMBER

摘要

A cap with a storage chamber for storing an ingredient to be added to a liquid content within a container (10) includes a base (110) to be attached to a mouth portion of the container, which has a spout (113) for allowing passage of the liquid content out of the container (10). A lid (120) is fastened by screwing to the base (110) and includes the storage chamber (124) and a thin sheet (123) for sealing it. The base (110) has an annular part (114a) fixed to an inner wall of the spout, for maintaining a channel communicating with an interior space of the container (10). The base (110) has a slanted blade (114b) which comes into contact with the thin sheet (123) as the lid (120) is moved downwards, for cutting the thin sheet and allowing the ingredient in the storage chamber (124) to fall into the interior space of the container (10) and mixed with the content therein.
