Abstract

A container that can be hermetically sealed including: a molded plastic container body with an open end having a side wall structure and a bottom wall structure formed with it in one piece at one of its ends, the container being open another end of the body of the container; a relatively thin and flexible inner diaphragm closure made of plastic that includes a generally disc-shaped central section, and an inverted channel located on its periphery, said diaphragm closure being adapted to be positioned downwardly on the periphery of the open end of the diaphragm. Container body, the disc-shaped central section extending downwardly in the container body with the inverted channel being adapted to be hermetically coupled with the side wall structure of the container body in a position adjacent to its open end, and the diaphragm closure susceptible to flexing in response to changes in pressure inside the sealed container; an outer closure made of a substantially more rigid material than the plastic material of the container body and including a generally disk-shaped central section and an inverted channel located on its periphery, said outer closure being adapted to be positioned down on top of the container body and diaphragm closure in order to close the open end of the container body, and the disc-shaped central section of the outer closure separated from the central section, in the form of a discoidal diaphragm seal; pressure relief means intended for external closure; and means for making a mutual fixation between the outer closure and the body of the container, whereby changes in pressure inside the sealed container are absorbed by the bending of the diaphragm closure, keeping the outer closure and the body of the container. It takes its respective normal configurations. (Machine-translation by Google Translate, not legally binding)
