(ii) a throat section of said beverage container, featuring a throat seal adapted to seal off the throat section of the container from communication with the outside portion, such that the entire throat section is in communication with the inside portion behind said contractable partition; and (iii) at least one air vent in the container surface corresponding to the outside portion, adapted to allow rapid equilibration of air pressure between the outside portion and ambient air pressure; and where, in use, said contractable partition expands or contracts to accommodate varying volumes of beverage within the inside portion while reducing the volume of air space above the beverage, thereby preventing the entry of contaminating air and reducing loss of carbonation. ### Claim 2 (depends on 1) The separation of air from fluids apparatus of claim 1, further adapted for use within a bottle-type beverage container. ### Claim 3 (depends on 1) The separation of air from fluids apparatus of claim 1, where said contractable partition is placed essentially in the middle of the beverage container. ### Claim 4 (depends on 1) The separation of air from fluids apparatus of claim 1, where said contractable partition is placed so as to form an inside portion less than one-half the volume of the beverage container. ### Claim 5 (depends on 1) The separation of air from fluids apparatus of claim 1, further adapted for use with a collapsible beverage container. ### Claim 6 (depends on 1) The separation of air from fluids apparatus of claim 1, where at least one said air vent is located near the throat of the beverage container. ### Claim 7 (depends on 1) The separation of air from fluids apparatus of claim 1, where at least one said air vent is located near the base of the beverage container. ### Claim 8 (depends on 1) The separation of air from fluids apparatus of claim 1, further adapted for use with a screw-cap-bottle beverage container. ### Claim 9 (depends on 1) The separation of air from fluids apparatus of claim 1, where said contractable partition and said throat seal further comprise a rubber material. ### Claim 10 (depends on 1) The separation of air from fluids apparatus of claim 1, where said contractable partition and said throat seal further comprise a silicone rubber material. ### Claim 11 A method of separating air from fluids for reducing carbonation loss in an open and resealed volume of beverage, the separation of air from fluids method comprising: (i) providing a separation of air from fluids apparatus, said apparatus comprising: (a) a contractable partition adapted to seal off a portion of a container, creating an inside portion and an outside portion within the container, and adapted to expand and contract to accommodate varying volumes of beverage within the inside portion; (b) a throat section of said beverage container, featuring a throat seal adapted to seal off the throat section of the container from communication with the outside portion, such that the entire throat section is in communication with the inside portion behind said contractable partition; and (c) at least one air vent in the container surface corresponding to the outside portion, adapted to allow rapid equilibration of air pressure between the outside portion and ambient air pressure; and (ii) using said separation of air from fluids apparatus, where, in use, said contractable partition expands or contracts to accommodate varying volumes of beverage within the inside portion while reducing the volume of air space above the beverage, thereby preventing the entry of contaminating air and reducing loss of carbonation. ### Claim 12 (depends on 11) The separation of air from fluids method of claim 11, where said separation of air from fluids apparatus is further adapted for use with a bottle-type beverage container. ### Claim 13 (depends on 11) The separation of air from fluids method of claim 11, where said contractable partition is placed essentially in the middle of the beverage container. ### Claim 14 (depends on 11) The separation of air from fluids method of claim 11, where said contractable partition is placed so as to form an inside portion less than one-half the volume of the beverage container. ### Claim 15 (depends on 11) The separation of air from fluids method of claim 11, where said separation of air from fluids apparatus is further adapted for use with a collapsible beverage container. ### Claim 16 (depends on 11) The separation of air from fluids method of claim 11, where at least one said air vent is located near the throat of the beverage container. ### Claim 17 (depends on 11) The separation of air from fluids method of claim 11, where at least one said air vent is located near the base of the beverage container. ### Claim 18 (depends on 11) The separation of air from fluids method of claim 11, where said separation of air from fluids apparatus is further adapted for use with a screw-cap-bottle beverage container. ### Claim 19 (depends on 11) The separation of air from fluids method of claim 11, where said contractable partition and said throat seal further comprise a rubber material. ### Claim 20 (depends on 11) The separation of air from fluids method of claim 11, where said contractable partition and said throat seal further comprise a silicone rubber material.
