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.
Claims9
Container comprising a body which comprises a first cylindrical portion, and a lid which comprises a second cylindrical portion of an internal diameter greater than the external diameter of the first cylindrical portion of the body, the lid being fitted by pushing the second cylindrical portion over the first cylindrical portion, the container furthermore comprising a safety device which comprises:
- a movable piece integral with a shutter which is held closed in sealing contact with a sealing means by the action of the pressure inside the container and which can be held open under the effect of a compressive force originating from outside,
- an outer surface forming part of the lid itself, said lid including said second cylindrical portion, which can move perpendicularly to the shutter and is capable of exerting said compressive force on the movable piece in order to hold the shutter open, and
- a cavity provided in said outer surface and traversing the wall of said lid and into which can penetrate the movable piece when it is aligned with said cavity, the shutter moving into the closing position when said movable piece penetrates into the cavity.
