Pressurized dispensing container with liner

Claim 1

A can for dispensing a product comprising a substantially dimensionally stable pressure-tight outer container including a container body having an upper annular shoulder terminating in an edge defining an opening of a first diameter, a valve plate sealingly secured at said edge, a dispensing valve carried by said valve plate, an at least partially deformable inner container arranged within said outer container, said inner container including a container body having an upper annular shoulder terminating at a neck which in turn includes an opening in fluid communication with said valve, said neck being substantially dimensionally stable however elastically deformable in a radial direction, said neck including a portion disposed between said inner container upper annular shoulder and said inner container opening and protruding radially beyond said neck, said protruding portion having a maximum external diametrical dimension in its undeformed condition which is greater than said first diameter whereby said protruding neck portion can temporarily rest exteriorly upon said edge while filling the inner container and will radially inwardly elastically deform under the influence of an axial force to temporarily lessen said maximum diametrical dimension thus permitting said protruding neck portion to pass through said outer container opening, and said protruding neck portion being positioned totally below said outer container edge and in non-contacting relationship thereto.
