ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a bottle stopper for bottle, and more particularly to a press-control bottle stopper, which enables the user to close/open the outlet of the bottle by means of a pressing operation.
In order to stop liquid from leaking out of a bottle container or to prevent contact of outside air with liquid in a bottle container, a matched bottle cap shall be used. Screw joint is a common design for enabling a bottle cap to be fastened to a bottle container. When picking up liquid from a bottle container, the bottle cap must be opened at first. After each service, the bottle cap must be closed on the bottle container again. When the bottle cap is removed from the bottle container, it may fall to the floor and contaminated with dirt. There are also known a bottle cap comprising a cap body for fastening to the bottleneck of a bottle container, the cap body having a center through hole, and a plug hinged to the cap body for plugging into the center through hole on the cap body to stop the passage. The plug and the cap body are formed integral with each other, and injection-molded from plastics. This structure of bottle cap is still not satisfactory in function because the hinged portion between the plug and the cap body tends to be broken when opening the plug from the cap body.
SUMMARY OF THE INVENTION
The present invention has been accomplished to provide a press-control bottle stopper, which eliminates the aforesaid problems. It is therefore the main object of the present invention to provide a press-control bottle stopper, which enables the user to close/open the outlet of the bottle by means of a pressing operation. According to the preferred embodiment of the present invention, the press-control bottle stopper is installed in the bottle neck of the bottle body of a bottle to close the passage of the bottle neck of the bottle body, comprising a hollow stopper shell, the stopper shell comprising a tubular coupling means fastened to the bottle neck of the bottle body, at least one water outlet for guiding liquid out of the bottle body, and an axial hole disposed at the center of a bottom side thereof, a plug installed in the stopper shell and moved between a close position and an open position to close/open the at least one water outlet, the plug comprising a plug stem inserted into the axial hole on the bottom side of the stopper shell, a spring member mounted on the plug stem inside the stopper shell to hold the plug head in the close position, and a plug head formed integral with one end of the plug stem and moved with the plug stem to close/open the at least one water outlet, a vessel-like hollow lining mounted inside the hollow stopper shell, the lining comprising a coupling portion fastened to an internal part of the hollow stopper shell, and a bottom center through hole axially aligned with the axial hole on the bottom side of the hollow stopper shell, a water passage defined within an inside wall of the hollow stopper shell around the periphery of the lining and disposed in communication with the at least one water outlet, and a control unit coupled to the inside of the vessel-like hollow lining and operated to close/open the at least one water outlet, the control unit comprising a hollow base press-fitted into the vessel-like hollow lining, a press-button mounted in the hollow base and moved axially relative to the hollow base, a push member coupled to the press-button at a bottom side and stopped against the plug stem of the plug for enabling the plug to be moved to the open position when the press-button is pressed by the user with the hand, and a release control member mounted in the hollow base and moved axially to release the push member from the plug for enabling the plug to be returned to the close position by the spring power of the spring member.
