Bottle cap and dispenser

Claim 2

A pressurizing cap which may be readily attached and detached from the discharge neck of a bottle of carbonated liquid, said cap comprising: a housing having a first chamber proximate an upper end thereof and a skirt portion at an opposite end thereof for detachably engaging said neck, said first chamber for retaining a pressurized canister of innoxious gas; a second chamber within said housing; a first conduit from said first chamber to said second chamber; a second conduit from said second chamber to said neck portion; and valve means for selectively connecting said first conduit to said second conduit whereby said gas is released into said bottle, said valve means comprising a piston slidably coupled within said second chamber and capable of being maneuvered between a first position wherein communication between said first and second conduits is blocked and a second position wherein gas from said first conduit will flow through said second conduit; a piston rod fixedly coupled to said piston and extending to the exterior of said housing; spring means coupled within said chamber for normally biasing said piston into said first position; and a handle pivotally coupled to said housing and engaging said piston rod for moving said piston to said second position.

Claim 3

A pressurizing cap according to claim 1 further comprising means for locking said piston in said first position.

Claim 4

A pressurizing cap according to claim 2 wherein said locking means comprises: a slot in said housing; a notch in said piston rod; a locking member slidably coupled in said slot for engaging said notch to lock said piston; and means coupled to said locking member and maneuverable from the exterior of said housing for unlocking said piston.

Claim 5

A pressurizing cap according to claim 2 further comprising a release valve in said housing through which excessive gas in said bottle may escape to the exterior of said housing.

Claim 6

A pressurizing cap according to claim 2 further comprising liquid discharge means extending from the interior of said bottle to the exterior of said housing.

Claim 7

A pressurizing cap which may be readily attached and detached from the discharge neck of a bottle of carbonated liquid, said cap comprising: a housing having a first chamber proximate an upper end thereof and a skirt portion at an opposite end thereof for detachably engaging said neck, said first chamber for retaining a pressurized canister of innoxious gas; a second chamber within said housing; a first conduit from said first chamber to said second chamber; a second conduit from said second chamber to said neck portion; and valve means for selectively connecting said first conduit to said second conduit whereby said gas is released into said bottle, said valve means comprising a piston slidably coupled within said second chamber and capable of being maneuvered between a first position wherein communication between said first and second conduits is blocked and a second position wherein gas from said first conduit will flow through said second conduit; a piston rod fixedly coupled to said piston; spring means coupled within said chamber for normally biasing said piston into said first position; and an actuator movably coupled to said housing and engaging said piston rod for moving said piston to said second position; liquid discharge means extending from the interior of said bottle to the exterior of said housing, said liquid discharge means comprising a third chamber; a first tube communicating at one end thereof with said third chamber and having an opposite end extending into said liquid; a third conduit extending from said third chamber and communicating with an opening in said housing; nozzle means extending from said opening to the exterior of said housing; and regulating means in said third chamber for regulating the volume of liquid passing through said liquid discharge means.

Claim 8

A pressurizing cap which may be readily attached and detached from the discharge neck of a bottle of carbonated liquid, said cap comprising: a housing having a first chamber proximate an upper end thereof and a skirt portion at an opposite end thereof for detachably engaging said neck, said first chamber for retaining a pressurized canister of innoxious gas; a second chamber within said housing; a first conduit from said first chamber to said second chamber; a second conduit from said second chamber to said neck portion; and valve means for selectively connecting said first conduit to said second conduit whereby said gas is released into said bottle, said valve means comprising a piston slidably coupled within said second chamber and capable of being maneuvered between a first position wherein communication between said first and second conduits is blocked and a second position wherein gas from said first conduit will flow through said second conduit; a piston rod fixedly coupled to said piston; spring means coupled within said chamber for normally biasing said piston into said first position; and an actuator movably coupled to said housing and engaging said piston rod for moving said piston to said second position; liquid discharge means extending from the interior of said bottle to the exterior of said housing, said liquid discharge means comprising a third chamber; a first tube communicating at one end thereof with said third chamber and having an opposite end extending into said liquid; a third conduit extending from said third chamber and communicating with an opening in said housing; nozzle means extending from said opening to the exterior of said housing; and regulating means in said third chamber for regulating the volume of liquid passing through said liquid discharge means.

Claim 9

A pressurizing cap according to claim 6 wherein said regulating means comprises: an adjustable alignment member having an opening therethrough; and means for varying the alignment of said opening with said third conduit and said tube.
