A bottle cap device as recited in claim 1, wherein said locking means comprises: a hook member formed in said annular wall of said cap body member and projecting outwardly therefrom; and a locking tongue integrally affixed to said lid member so as to snap over said hook member when said lid member is placed in a closed sealed position over said cap body. 7. A bottle cap device as recited in claim 6, wherein said locking tongue includes a pair of flexible front leg members connected to said lid member. 8. A bottle cap device as recited in claim 7, wherein said bottle cap device includes means for positioning said gasket therein. 9. A bottle cap device as recited in claim 8, wherein said gasket-positioning means comprises: an annular, outer, depending flange member formed on said gasket, said outer depending flange member having a pair of notches formed therein; and a pair of tab members formed in said inner surface of said annular wall of said cap body member so as to be received in said notches of said gasket, whereby said breathing tube is disposed in a selected position within said cap body member. 10. A bottle cap device as recited in claim 2, wherein said gasket includes an inner annular, inclined, sealing lip, said sealing lip being positioned to engage said convex sealing member formed as a depending semi-spherical wall. 11. A bottle cap device as recited in claim 2, wherein said means for latching said lid member in an open position comprises: a longitudinal rib member formed along said pivot pin of said lid member; and a nipple member formed on said lower arm and positioned to engage said rib member as said lid member is rotated to a fully open position. 12. 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 and a mouth formed by an upper planer surface with an inner edge, the improvement comprising: a bottle cap having an annular cap 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, the cap including an inwardly projecting shoulder arranged to extend over the upper planer surface of the bottle mouth; a lid member hingedly attached to said body member for pivoting from an open to a closed position, the lid member having a downwardly projecting convex sealing surface whereby said open end of said body member is covered by the cap member in the closed position; and a gasket having an annular ring extending between the upper planer surface of the bottle mouth and the inwardly projecting shoulder of the cap body member to form a seal therebetween and a sealing lip member extending from the annular ring to form a seal between the inner edge of the bottle mouth and the downwardly projecting convex sealing surface on the lid member when the lid member is in a closed position. 13. The combination as recited in claim 12 wherein the cap body member has an annular wall and, further including locking means positioned between said lid member and said body member, the locking means comprising: a hook member formed in said annular wall of said cap body member and projecting outwardly therefrom; and a resilient locking tongue integrally affixed to said lid member so as to snap over said hook member when said lid member is placed in a closed sealed position over said cap body. 14. The combination as recited in claim 13, wherein said gasket includes an air inlet means, whereby air enters the bottle from the air inlet means as fluid from the bottle is being discharged. 15. The combination as recited in claim 14, wherein said air inlet means comprises an elongated tube member; and wherein said hinge means comprises: a pair of upper hinge members attached to said cover member, said upper hinge members being spaced apart from each other; a lower hinge member mounted below and between said upper hinge members; and a pivot pin secured to said cover member, said pivot pin being mounted between said upper and lower hinge members, whereby said cover member is rotatably mounted to said body member. 16. The combination as recited in claim 13, wherein said locking tongue includes a pair of flexible front leg members connected to said lid member with a locking tongue extending between the terminal ends of the leg members. 17. The combination as recited in claim 12, wherein said convex sealing surface of said lid member is defined by a depending convex wall having a semi-spherical configuration that compresses the sealing lip member of said gasket against the inner edge of the mouth of the bottle when the cover is locked in a closed position. 18. The combination as recited in claim 12 wherein the sealing surface of the lid member comprises a semi-spherical surface for compressing the sealing lip member of the gasket against the inner edge of the bottle mouth when the lid member is in the closed position. 19. The combination of a bottle used for the storage of gaseous liquids of the type wherein the bottle is formed having a threaded discharge neck portion, and a bottle cap for closing the discharge neck portion, an improved bottle cap comprising: 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; a cover member hingedly attached to said body member whereby said open end of said body member is covered; a hinged means hingedly connecting said cover member and said body member, and including a latch-positioning means, whereby said cover member is held in an open position when the bottle is oriented to discharge liquid therein; locking means positioned between said cover member and said body member, whereby said cover member is locked in a sealed position; a gasket mounted within said cap body member; and a convex sealing member defining a sealing means formed as part of said cover member so as to engage said gasket whereby a positive seal is established therebetween. 20. The combination as recited in claim 19, wherein said gasket comprises a ring member having an outer annular, depending flange member and an inner angularly depending lip member, said lip member being positioned within said body member to engage said convex sealing member of said cover member. 21. In combination with a bottle of the type wherein the bottle is formed with a discharge neck portion having external threads and an upper planar surface and an inner edge at the mouth of the bottle, an improved bottle cap for selectively opening and closing the neck portion comprising: a cap body member having an annular wall with an outer surface, an inner surface and an inwardly projecting surfaces for extending over the upper planar surface of the mouth of the bottle, the inner surface being formed with threads for mounting to the threaded neck portion of the bottle; a lid member hinged to the cap body member for rotation between a closed and an open position; cooperating locking means mounted on the lid member and the cap body member, whereby the lid member may be secured by the locking means in a sealed and locked position; a gasket mounted within the cap body member, the gasket including an annular ring member extending between the inwardly projecting surface of the cap body member and the upper planar surface of the bottle neck and a sealing lip member extending inwardly from the annular ring member; and a semi-spherical sealing surface formed as part of the lid member for compressing the sealing lip member of the gasket against the inner edge of the mouth of the bottle in the closed position. 22.
