The device comprises at least a container which contains an oxygen absorber to remove oxygen remaining in the bottle or vessel after it is sealed by the preservation device. The container or the oxygen absorber has a gas permeable, liquid impermeable membrane. The preservation device may include an air channel system to control the flow of the liquid to be dispensed from the bottle without requiring the removal of the entire stopper device from the bottle, to enable the liquid to be dispensed while only allowing a minimal amount of oxygen to enter the bottle, thus improving preservation. ## Claims ### Claim 1 A preservation device for use with a bottle having a neck comprising: a first member having at least a flange configured to fit outside a neck of a bottle, and a tube configured to fit within the neck of the bottle, wherein the tube is separated into at least a first portion and a second portion, and wherein the first portion of the tube is separately enclosed along its length and configured to only permit a flow of air, and wherein a second portion of the tube is separably enclosed and configured to only permit a flow of liquid; a second member operably connected to the tube at an end distal to the flange, configured to fit within the neck of the bottle, wherein the second member comprises at least one inner channel; at least one sealing member extending around an outer surface of the first member for substantially preventing the flow of liquid or air into or out of the bottle around the outer surface of the first member, when the first member is disposed within the neck of the bottle; and a container for holding an oxygen absorber, the container being detachably connected to an end of the second member distal to the first member, and the container having at least one side wall and at least one aperture. ### Claim 2 (depends on 1) The preservation device of claim 1, wherein the at least one inner channel is an air channel extending from an air vent, through the first portion of the tube, and to an end of the tube distal to the second member, and wherein the air vent is disposed in a side wall of the second member at an end of the second member proximate to and above the container. ### Claim 3 (depends on 2) The preservation device of claim 2, further comprising a liquid channel wherein the liquid channel comprises the second portion of the tube, and the liquid channel extends through the tube of the first member from an end of the tube proximate to the flange to an end of the tube distal to the flange. ### Claim 4 (depends on 3) The preservation device of claim 3, wherein the end of the tube proximate to the flange further comprises a pour spout in liquid communication with the liquid channel. ### Claim 5 (depends on 4) The preservation device of claim 4, further comprising a lid having a first side and a second side, wherein at least the second side of the lid is configured to fit within and substantially seal the pour spout. ### Claim 6 (depends on 2) The preservation device of claim 2, wherein the air channel comprises of a first air channel and a second air channel. ### Claim 7 (depends on 6) The preservation device of claim 6, wherein a key connects the first air channel to the second air channel. ### Claim 8 (depends on 1) The preservation device of claim 1, wherein the at least one sealing member is configured to fit inside the neck of the bottle. ### Claim 9 (depends on 1) The preservation device of claim 1, wherein the oxygen absorber has a membrane that is liquid impermeable and air permeable. ### Claim 10 A preservation device for use with a bottle having a neck comprising: a first member having at least a flange configured to fit outside a neck of a bottle, and a tube configured to fit within the neck of the bottle, wherein the tube comprises a first liquid channel configured to permit a flow of a liquid through the tube and a first air channel configured to permit a flow of air through the tube, and wherein the first liquid channel is enclosed separately in the tube from the first air channel; a second member operably connected to the tube at an end distal to the flange, configured to fit within the neck of the bottle; at least one sealing member extending around an outer surface of the first member for substantially preventing the flow of liquid or air into or out of the bottle around the outer surface of the first member, when the first member is disposed within the neck of the bottle; and a container for holding an oxygen absorber, the container being detachably connected to an end of the second member distal to the first member, and the container having at least one side wall and at least one aperture. ### Claim 11 (depends on 10) The preservation device of claim 10, wherein the first air channel extends through the tube of the first member from an end of the tube proximate to the flange to an end of the tube distal to the flange, and the first liquid channel extends through the tube of the first member from the end of the tube proximate to the flange to the end of the tube distal to the flange. ### Claim 12 (depends on 11) The preservation device of claim 11, further comprising a second air channel within the second member extending from an air vent, disposed on a side wall at an end of the second member proximate to and above the container, to an end of the second member proximate to the first member. ### Claim 13 (depends on 12) The preservation device of claim 12, wherein the first air channel connects to the second air channel, and the first air channel and the second air channel extend from the air vent to an end of the first member distal to the second member. ### Claim 14 (depends on 13) The preservation device of claim 13 wherein a key connects the first air channel to the second air channel. ### Claim 15 (depends on 10) The preservation device of claim 10, wherein the end of the tube proximate to the flange further comprises a pour spout. ### Claim 16 (depends on 15) The preservation device of claim 15, wherein the pour spout is at least in fluid communication with the tube. ### Claim 17 (depends on 15) The preservation device of claim 15, further comprising a lid having a first side and a second side, wherein at least the second side of the lid is configured to fit within and substantially seal the pour spout. ### Claim 18 (depends on 10) The preservation device of claim 10, wherein the at least one sealing member is configured to fit inside the neck of the bottle. ### Claim 19 (depends on 10) The preservation device of claim 10, wherein the oxygen absorber has a membrane that is liquid impermeable and air permeable.
