Prior art bottle closures having a stationary closure member applicable to the top of a bottle and a closure member that is movable relative to the stationary closure member are improved by incorporation, between said closure members, of mutually cooperative, fluid sealing members extending transversely of the pouring axis of the bottle closures and separable therefrom for preventing escape of gaseous ingredients, such as carbonation, of drinkable liquids contained by bottles to which the bottle closures are applied.

[ I claim:] [1.] A closure for bottles intended to hold a carbonated beverage or other beverage containing a gaseous constituent, said closure being adapted for momentarily opening the bottle to obtain a drink and for then reclosing the bottle to protect the contents against dissipation of the gaseous constituent of the beverage contained by the bottle, said bottle closure comprising cooperative closure members extending along the pouring axis of the bottle closure, one of said closure members being stationary relative to the other when applied to a bottle; said one, stationary closure member being formed for screwing onto and sealing against an externally threaded, pouring top of the bottle to which it is to be applied, and having a normally upper, stopper post portion with a closed top, intermediate and normally lower cylindrical portions, respectively, and a portion of spider formation rigidly connecting said stopper post portion with said cylindrical portions, said spider portion extending transversely of said pouring axis between said stopper post portion and said cylindrical portions and having liquid dispensing openings arranged circumferentially of said stopper post portion and of said cylindrical portions and directed from entry thereof to discharge therefrom along said pouring axis of the bottle closure; said other of the closure members being movable axially of the bottle closure relative to the said one, stationary closure member for opening and reclosing the bottle with which the bottle closure is used; a compression seat associated with one or the other of said closure members for coacting with a sealing ring member, said seat surrounding said stopper post portion circumferentially thereof and extending transversely of the pouring axis of the bottle closure; a sealing ring member operationally associated with one or the other of said closure member but separable therefrom and extending transversely of said pouring axis for compressively bearing against said compression seat when the bottle closure is in closed condition for tight sealing action therewith against escape therethrough of the gaseous constituent of a beverage contained by said bottle; said other, movable closure member circumferentially encircling said cylindrical portion of said stationary closure member; a second compression seat associated with one or the other of said closure member for a second sealing ring member and extending transversely of said pouring axis of the bottle closure; and a second sealing ring member operatively associated with one or the other of said closure member but separable therefrom and extending transversely of said pouring axis of the bottle closure for compressively bearing against said second compression seat when the bottle closure is in closed condition for tight sealing therewith against escape therethrough of the gaseous constituent of a beverage contained by said bottle when the bottle closure is in closed condition relative to said bottle.
