Abstract
Abstract This disclosure pertains to a carbonated beverage container closure apparatus adapted to be removably secured to the container's mouth. A valve is biased to close an opening in the closure having the closing biased forces reinforced by the pressurized gas within the container. A pump apparatus is threadingly engaged on the closure device and is adapted with a check valve such that manual operation of the pump causes the valve in the closure device to open whilst the check valve is closed and air, under pressure, is injected into the container. The pump apparatus may be removed from the container closure device, enabling the container to be stored in a substantially non-heightened profile and enabling the pump apparatus to re-pressurize other containers equipped with similar closure devices.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
183 words
A pressurizing closure apparatus for closing the opening in a container that contains a carbonated liquid or the like comprising in combination: a closure device for removable engagement over said opening in said container, said closure device for sealing said opening; first check valve means disposed in said closure device that passes air in a first direction through said closure device to the internal volume of said container and opposes the passage of said air in the reverse direction and out of said container; a pump device for intermittantly generating compressed air within a cavity thereof, second check valve means disposed in the walls of said cavity, said second check valve means passing air in a second direction through said walls of said cavity to the internal volume of said cavity and opposing the passage of air in the reverse direction and out of said cavity, said pump device removably secured to said closure device utilizing pump device securing means therefor; and handle means, said handle means for providing said compressed air within said cavity upon the application of manually applied force thereto.
Claim 2
Dependent Claim
183 words
A pressurizing closure apparatus for closing the opening in a container that contains a carbonated liquid or the like comprising in combination: a closure device for removable engagement over said opening in said container, said closure device for sealing said opening; first check valve means disposed in said closure device that passes air in a first direction through said closure device to the internal volume of said container and opposes the passage of said air in the reverse direction and out of said container; a pump device for intermittantly generating compressed air within a cavity thereof, second check valve means disposed in the walls of said cavity, said second check valve means passing air in a second direction through said walls of said cavity to the internal volume of said cavity and opposing the passage of air in the reverse direction and out of said cavity, said pump device removably secured to said closure device utilizing pump device securing means therefor; and handle means, said handle means for providing said compressed air within said cavity upon the application of manually applied force thereto.
Claim 3
Dependent Claim
38 words
The pressurizing closure apparatus as claimed in claim 1 wherein said first check valve means comprises a ball, a spring, said ball being biased outwardly against an opening in the surface of said closure device by said spring.
Claim 4
Dependent Claim
55 words
The pressurizing closure apparatus as claimed in claim 1 wherein said first check valve means comprises a flapper valve, said flapper valve closing an opening in the surface of said closure device when said internal volume of said container attains a pressure level greater than the pressure level of the outside air surrounding said container.
Claim 5
Dependent Claim
73 words
The pressurizing closure apparatus as claimed in claim 1 further comprising said closure device having a cylindrical external surface, first threads being disposed on said cylindrical exterior surface, said first threads for threading engagement with said pump device, tab means extending radially outwardly from said cylindrical exterior surface, a lateral surface being fixedly secured to one end of said cylindrical exterior surface, said first check valve means being disposed within said lateral surface.
Claim 6
Dependent Claim
55 words
The pressurizing closure apparatus as claimed in claim 4 wherein said closure device further comprises second threads being disposed on an innermost cylindrical surface thereof, said innermost cylindrical surface co-axially aligned with said cylindrically exterior surface, said second threads for threading engagement with the external surface of said container adjacent said opening in said container.
Claim 7
Dependent Claim
42 words
The pressurizing closure apparatus as claimed in claim 4 wherein said pump device comprises a bellows assembly, one end of said bellows assembly fixedly secured to said pump device securing means, the other end of said bellows assembly enclosing said cavity thereof.
Claim 8
Dependent Claim
114 words
The pressurizing closure apparatus as claimed in claim 6 wherein said handle means comprises a pair of handles, one end of one of said pair of handles fixedly secured to said pump device securing means, one end of the other of said pair of handles in touching engagement with said other end of said bellows assembly, mechanical advantage means for applying greater forces to said one end of said one of said pair of handles and said one end of said other of said pair of handles than said manually applied forces to the other end of said one of said pair of handles and the other end of said other pair of handles.
Claim 9
Dependent Claim
49 words
The pressurizing closure apparatus as claimed in claim 7 wherein said pump device further comprises a third cylindrical interior surface, said third cylindrical interior surface having third threads disposed thereon, said third threads for threading engagement with said first threads on said cylindrical external surface of said closure device.
