ABSTRACT:
A disassemblable container capable of sustaining pressure and disassemblable into a body and a lid and which is assembled with a leaktight seal includes a piece which is movable but integrally connected to the body and is pushed into a cavity of the lid under the effect of the internal pressure acting on a shutter and in opposition to an elastic return member. By pressing the movable piece, the shutter is brought into a pressure-release position. The shutter prevents the opening of the container when under an excessively high pressure and advantageously also serves as a safety shutter against overpressures.
