Device for dispensing liquids from a sealed container and for preserving undispensed portions thereof

Claim 1

A device for preserving perishable liquids in a container sealed by a cork-type closure and for providing means for selectively removing the liquids from the container comprising: an elongated housing having first and second compartments, said compartments being separated by a partition having an opening therethrough, means for releasably retaining a pressurized canister of an innoxious gas in said first compartment and means for puncturing such a canister to release the gas therein into the first compartment, a diaphragm in said second compartment dividing the compartment into first and second sections, and resilient means in said second section yieldingly resisting flexing movement of the diaphragm into the second section, said housing having a vent opening therethrough in communication with said second section such that said second section is pressurized at the ambient atmospheric pressure, closure means operatively connected to said diaphragm for selective movement therewith, said closure means normally operative to close said opening in the partition between compartments but movable with selected movement of the diaphragm to open said opening, first conduit means in fluid communication with said first section and having means adapted to enable the conduit to penetrate the cork-type closure of the container to establish fluid communication between the first section and the interior of said bottle such that innoxious gas can be selectively transferred from the housing to the container, second conduit means connected to said housing and also having means adapted to enable the second conduit to penetrate the cork-type closure of the container, said second conduit providing means for removing liquid from the container, and valve means in said second conduit means to control the flow of liquid therethrough.

Claim 2

A device for preserving perishable liquids in a container sealed by a cork-type closure and for providing means for selectively removing the liquids from the container comprising: an elongated housing having first and second compartments, said compartments being separated by a partition having an opening therethrough, means for releasably retaining a pressurized canister of an innoxious gas in said first compartment and means for puncturing such a canister to release the gas therein into the first compartment, a diaphragm in said second compartment dividing the compartment into first and second sections, and resilient means in said second section yieldingly resisting flexing movement of the diaphragm into the second section, said housing having a vent opening therethrough in communication with said second section such that said second section is pressurized at the ambient atmospheric pressure, closure means operatively connected to said diaphragm for selective movement therewith, said closure means normally operative to close said opening in the partition between compartments but movable with selected movement of the diaphragm to open said opening, first conduit means in fluid communication with said first section and having means adapted to enable the conduit to penetrate the cork-type closure of the container to establish fluid communication between the first section and the interior of said bottle such that innoxious gas can be selectively transferred from the housing to the container, second conduit means connected to said housing and also having means adapted to enable the second conduit to penetrate the cork-type closure of the container, said second conduit providing means for removing liquid from the container, and valve means in said second conduit means to control the flow of liquid therethrough.
