Claim:
A dispensing apparatus, comprising: a housing having a support platform shaped and dimensioned for supporting at least one bottle may be supported; a pressurized gas supply assembly for forcing a fluid from the at least one bottle; the pressurized gas supply assembly includes an inert gas output which is linked to the at least one bottle via a conduit arrangement and a dispensing nozzle selectively secured within an opening of the at least one bottle; the dispensing nozzle including a connecting seal assembly for attaching the dispensing nozzle within the opening of the a least one bottle, the connection seal assembly extends downwardly and substantially covers a downwardly extending substrate of the dispensing nozzle, and the connecting seal assembly includes a self-energizing seal; wherein the self energizing seal is cylindrical and includes an outer wall shaped and dimensioned to engage an inner wall of the opening of the at least one bottle, the self-energizing seal also includes an inner wall having a central portion which is spaced from an outer surface of the downwardly extending substrate of the dispensing nozzle and defines, in conjunction with the outer surface to the downwardly extending substrate of the dispensing nozzle, a cavity which is in communication with the pressurized gas supply assembly for expanding the self-energizing seal and forcing the self energizing seal into contact with an inner wall of the opening of the at least one bottle.
