ABSTRACT:
A cap device for bottles, which smoothly and naturally removes a vacuum pressure from a cavity containing an additive therein by opening a valve cock in response to a rotating action of a cap body. The cap device having a cap body provided with a cavity to contain an additive therein and tightened to an externally threaded mouth of a bottle. A funnel part being integrally formed in the cap body to discharge the additive from the cavity into the bottle through a lower end thereof. A small vent hole being formed at a top surface of the cap body. A breakable sheet being attached to the lower end of the funnel part to close the lower end of the funnel part. A valve cock being provided at the vent hole of the cap body to open or close the vent hole. A projection being provided at a predetermined position on a top edge of the mouth of the bottle to thrust and open the valve cock with downward rotation of the cap body. The cap device also has a valve having a structure capable of allowing a liquid to pass therethrough. The valve being placed in a neck of the bottle, such that the valve thrusts and breaks the breakable sheet when the cap body is rotated to move downward relative to the mouth of the bottle.
