Abstract
An improved bottle cap device formed so as to have a positive sealing arrangement for use with bottles that store gaseous fluid such as soda water and like beverages, wherein the bottle cap device includes a threaded cap body and a hinged cover or lid that is formed having a sealing annular structure which compresses an annular gasket against the mouth of the bottle by a depending convex wall that engages a gasket mounted when the cover is locked in a close sealed position and a pressure release latch for limiting the movement of the hinged cover after it is unlocked from the cap body to relieve pressure within the bottle.
Claims16
A bottle cap device for sealing gaseous liquids stored within a bottle having a threaded neck portion, said bottle cap device comprising:
- a cap body member having an annular wall with an outer surface and an inner surface, said inner surface being formed with threads, whereby said bottle cap device is adapted to be threaded to the neck portion of the bottle;
- a cover lid member;
- a hinge means mounted between said lid member and said cap body member, whereby said lid member may be pivoted at said hinge means from a closed position to an open position;
- locking means positioned between said lid member and said cap body member, the locking means comprising at least one locking hook on the cap body member and a locking tongue on the lid member, whereby said lid member is held by said locking means in a sealed locked position;
- a gasket mounted within said cap body member;
- sealing means formed as part of said lid member so as to engage said gasket, whereby a positive seal is established between said sealing means and said gasket;
- and
- pressure release means for arresting the movement of the lid member after the disengagement thereof from said gasket to allow gas to escape from the bottle and relieve any pressure build up therein.
In combination with a bottle used for the storage of gaseous fluids of the type wherein the bottle is formed having a threaded discharge neck portion, the improvement comprising:
- a bottle cap having an annular body member with an open end and internal threads formed therein, whereby said bottle cap is threadably secured to the threaded neck portion of the bottle and a cover member for the open end of the body member;
- means hingedly connecting the cover member and the body member whereby the cover member may be rotated with respect to the body member;
- locking means positioned between the cover member and the body member, the locking means comprising at least one locking hook on the cover member and a locking tongue on the body member, whereby the cover member is locked in a sealed position to prevent gaseous fluid from exiting the neck portion of the bottle;
- a gasket mounted within said cap body member;
- an annular sealing member formed as part of said cover member so as to engage said gasket whereby a positive seal is established between said cover member and said gasket and said discharge neck portion of the bottle;
- and
- pressure release means positioned between the cover member and the body member for selectively limiting the rotation of the cover member when the cover member is not in a locked and sealed position.
