A system, apparatus, container and method of dispensing a liquid from a disposable container is disclosed. The apparatus includes a cylindrical shroud which receives a filled disposable container; the latter having one or more circumferential rings around its body of a different diameter from that of the container and a mouth. The shroud has a cap assembly which is telescopically received by a lower portion of the shroud with the shroud cap assembly having a stopper for sealingly mating with the container mouth. The shroud with the container therein and with the telescoping shroud cap assembly in place is fitted within a frame which positively prevents axial movement of the telescoping cap assembly relative to the other portion of the shroud beyond a predetermined limit. A range in container lengths may be accommodated and the circumferential rings permit longer containers to be axially compressed as the shroud is inserted in the frame. With the shroud in the frame, the container is internally pressurized via the stopper so that the circumferential rings permit the container to move substantially freely in axial direction so as to insure that the axial force is applied to the ends of the container thereby to insure a good seal is made between the container mouth and the stopper.

Apparatus for dispensing liquid from a disposable container, said disposable container having a mouth, said apparatus comprising means for withstanding pressurization forces exerted on said container upon internal pressurization thereof, said pressure withstanding means comprising a shroud having a first portion for receiving at least in part a portion of said disposable container and having another portion receiving another portion of said disposable container with said shroud portions being axially movable relative to one another, said pressure withstanding means further comprising a frame for receiving said shroud with said disposable container therein, said frame preventing outward axial movement of said shroud portions beyond a predetermined limit, said shroud including means sealably engagable with said disposable container for admitting pressurizing gas into the interior of said dispoable container and for permitting the dispensing of liquid therefrom, said container having means for permitting elongation and compression within a limited range between a shortest permissible length and a maximum permissible length, said shroud further oomprising means for accommodating a range of lengths of said disposable container, this last said means comprising said shroud portions being telescopic and permitting a disposable container of a shortest permissible length to be readily sealed relative to said means sealably engagable with said container and permitting a container of a maximum permissible length to be compressed in axial direction as said shroud with said container received therein is inserted in said frame so that upon internal pressurization of said container, a positive seal is made between said means sealably engagable with said container and said container.
