20110168659 | Bottle Cap Device - A bottle cap device for a container includes a bottle cap, a subpackage vessel, a guiding structure, and a linkage structure. A retainer groove and a retainer member form a clutch structure, wherein the retainer groove and the retainer member are mated with each other and are disposed between said bottle cap and an outside surface of a top periphery of the subpackage vessel. A circular slotting tool is disposed within a containing cavity, wherein said circular slotting tool has a center hole and a cutting edge protruded on the bottom thereof. The guiding structure is disposed between said slotting tool and said subpackage vessel, wherein when the slotting tool is turned anticlockwise, the guiding structure limits the slotting tool to move downwards. The linkage structure includes a neck-shrinking helical block protruded downwardly from the bottom surface of the cover, and has a helical groove provided in a sidewall of a center hole of the slotting tool for mating with the helical block, wherein when the bottle cap is turned anticlockwise, the helical block pushes said helical groove to force the slotting tool to move under limitation of the guiding structure, and thus a cutting edge of the slotting tool opens a bottom separator of the subpackage vessel. | 07-14-2011 |
