A thin walled, easily crushable container with an integral or seamed-on bottom isfilled with an edible material which requires sterilization. The empty container has one end attached or integral that may have a concave slope relative to the inside of the container. A liquified or solidified inert gas is then inserted into the container. The container is then sealed with a concave shaped end before the inert liquified or solidified gas has completely vaporized. The ends are such that they do not bulge under the pressure left after sterilization, which pressure is due to the pressurization effect of the inert gas and which pressure is enough to overcome the vacuum caused by the cooling of hot water vapor or steam above the edible material and gives the can the required rigidity. If one end is concave shaped and will invert or bulge at bacterial gas pressure but not at the gas pressure left after sterilization, then the other end does not necessarily have to be concave as long as it does not bulge at the pressure left after sterilization.

[ What is claimed is:] [1.] A pressurized sealed container containing sterilized edible material, which comprises:a thin wall sealed container containing edible material sterilized in a sterilization process and an inert gas under pressure, the walls of the container being maintained rigid by the pressure of the inert gas but being easily deformable in the absence of such pressure, the container having a top end and a bottom end with at least one end having a concave slope relative to the inside of the container, the at least one end being of a material and having a thickness and shape such that said at least one end of said sealed container will retain a substantially concave slope before, during and after said sterilization process but will become convex only if there is any additional gas pressure generated due to bacterial action in the pressurized sealed container.
