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, performed by a user, thus allowing the user to easily prepare the mixture just before drinking or using the mixture. The cap device also allows the mixture to be quickly discharged from the container. The cap device for bottles of the present invention includes a valve unit closely and removably fitted over a mouth of a bottle. An additive containing unit externally and removably engages with the valve unit, and the additive containing unit defines a cavity therein to contain an additive.

Claims

1. A cap device for engagement with a bottle, said cap device comprising:

a valve unit closely and removably fitted over a mouth of said bottle;

an additive containing unit externally and removably engaging with the valve unit, said additive containing unit defining a cavity therein for containing an additive;

wherein the valve unit further comprises

a cap body having a lower threaded inner surface and an upper threaded inner surface;

said lower threaded surface being removably engaged with said mouth of the bottle;

a conical valve part formed at an intermediate portion in the cap body;

a funnel part provided at a lower portion of the additive containing unit, said additive containing unit having a threaded lower portion to removably engage with the upper threaded inner surface of the cap body;

wherein an opening formed at the lower end of the funnel part is closed by the conical valve part when said additive containing unit is tightened completely onto said cap body; and

,

wherein said lower end of the funnel separates from said conical valve part when said additive containing unit is being removed from said cap body.

2. A bottle having a mouth, said mouth having a threaded outer surface, said bottle comprising:

a cap device for engagement with said bottle, said cap device comprising;

a valve unit closely and removably fitted over said mouth of said bottle;

an additive containing unit externally and removably engaging with the valve unit, said additive containing unit defining a cavity therein for containing an additive;

wherein the valve unit further comprises

a cap body having a lower threaded inner surface and an upper threaded inner surface;

said lower threaded surface being removably engaged with said mouth of the bottle;

a conical valve part formed at an intermediate portion in the cap body;

a funnel part provided at a lower portion of the additive containing unit, said additive containing unit having a threaded lower portion to removably engage with the upper threaded inner surface of the cap body;

wherein an opening formed at the lower end of the funnel part is closed by the conical valve part when said additive containing unit is tightened completely onto said cap body; and

,

wherein said lower end of the funnel separates from said conical valve part when said additive containing unit is being removed from said cap body.
