Improvements in pressure-supplied containers, especially suitable for sterilized viscous materials, characterized in that they comprise an external open-mouth cover bearing a flange; an internal cover with a crushable semi-rigid open mouth filled with the material to be supplied, and mounted concentrically inside said external cover, having a rigid base of area slightly smaller than that of said base of said external cover, and a widened portion of neck adjacent to its open mouth, said enlarged neck portion having substantially the same outer diameter as the inner diameter of said outer cover and taking frictional contact with said outer cover and supporting in spaced form said inner cover within said external cover, having said inner cover a length less than said outer cover and having a flange surrounding its open mouth contacting said flange on said outer cover; valve means fixed with double seam on said flanges of said external and internal covers hermetically closing said internal cover and forming a hermetic chamber between said external and internal covers; said chamber being filled with a measured amount of a preferably liquefied or solidified propellant, thus a uniform gas pressure being exerted on the side walls of said collapsible, semi-rigid inner sheath; while said inner cover consists of a material that is impermeable for the material to be supplied and for the propellant, and withstanding the usual conditions of sterilization.
