Container and process for its manufacture

Vacuum-sealed container, including contents and having an upper part and an element integral with the upper part, a housing defined by the upper part and by the element, the housing containing a solid substance having a melting point between 65.degree. C. and 150.degree. C. and including a first orifice communicating with an interior region within the container and a second orifice communicating with an exterior region outside the container the second orifice being adapted to be closed by the solid substance.

Process for the manufacture of a container having an upper part and a remaining part adapted to receive contents to be contained, comprising the sequential steps of providing a substance having a melting point between 65.degree. C. and 150.degree. C. in a housing defined in the upper part of the container that communicates with an interior region of the container via a first orifice and with an exterior region remote of the container via a second orifice, heating the container and its housing to a temperature at least equal to the melting point of the substance for 5 to 90 minutes, cooling the substance to a temperature lower than its melting point more rapidly than the remainder of the container and its contents, and cooling the remainder of the container and its contents to a temperature lower than or equal to ambient temperature.
