Cap device for mixing different kinds of materials separately contained therein and in bottle
First Claim
1. A cap device for a bottle having an externally threaded mouth and a neck with a tapered inner surface, said cap device comprising:
- a cap body twistably attaching to said externally threaded mouth of said bottle;
a funnel part integrated with said cap body, said funnel part having an opening at a lower end thereof;
a cap cover assembled with the cap body to define a cavity for containing an additive in said cavity;
a valve member for closing and opening said opening at said lower end of said funnel part said valve member having a valve part at a center thereof and a shank extending upward from said valve par, said shank extending into said cap body through said opening at said lower end of said funnel part;
wherein said valve member is removeably seated within said neck of said bottle and sealing said opening of said lower end of said funnel part when said cap body is completely twisted onto said bottle; and
, wherein said valve member is disengaged from within said neck of said bottle and not sealing said opening of said lower end of said funnel part when said cap body is twisted off said bottle.

Abstract
A cap device for bottles, which is capable of mixing an additive contained therein with a material contained in a bottle to prepare a mixture in accordance with a simple rotating action of the cap device relative to the bottle, and which allows the mixture to be quickly discharged from the container. In the cap device of the invention, having a valve member seated in a neck of a bottle; a cap body tightened to an externally threaded mouth of a bottle and opened or closed at a lower end of a funnel part thereof by the valve member; and a cap cover acting as an additive containing part and assembled with the cap body to define a cavity therein to contain an additive in the cavity, the neck of the bottle is tapered downward on an inner surface thereof; the valve member is provided with a valve part at a center thereof to open or close the lower end of the funnel part of the cap body, with a plurality of radial ribs extending outward from an external surface of the valve part while defining a plurality of additive discharging holes between the radial ribs, the valve member also having a ring to surround outside ends of the radial rings, and a wedge-tipped shank vertically extending upward from a center of the valve part; a tapered surface is formed along an outer surface of the ring to correspond to the tapered inner surface of the neck of the bottle; and a vent hole is formed at a predetermined position of an upper end of the funnel part of the cap body.
