Abstract
A wine preserving assembly which simultaneously delivers an inert-gas to the headspace of a wine bottle while simultaneously evacuating undesirable gas contained in the headspace through the action of operatively engaging an inert gas-containing vessel to the wine preserving assembly.
Claims1
In a particular aspect of the present invention, there is provided a wine preserving assembly comprising:
- a) a housing having a lower housing portion, a middle housing portion and an upper housing portion, said lower housing portion being insertable into the neck of a wine bottle;
- b) said upper housing portion having an opening for releasably receiving an inert gas-containing vessel and being separated from the middle housing portion by at least one pathway;
- c) a pin adapted to penetrate the inert gas-containing vessel and to deliver the insert gas to a piston assembly;
- d) a first passageway for delivering at least a portion of the inert gas from the piston assembly through an opening in the lower housing portion;
- and
- e) said piston assembly upon contact with the inert gas, moving to a position causing the lower housing portion to separate from the middle housing portion to form a gap to enable gas contained within the headspace to enter the gap and exit through a second passageway between the upper housing portion and middle housing portion.
