Patent ID: 6871754

Claim:
A container for enclosing a fluid under variable pressure, comprising a tubular element ( 1 ) comprising an outer end defining an opening ( 2 ) and axial locking means ( 8 , 9 ) adjacent the opening; said axial locking means including a first slot ( 8 ) in a wall of the tubular element and a second slot ( 9 ) diametrically opposed to the said first slot; a plug ( 3 ) closing the opening and introduced by axial sliding into the said tubular element ( 1 ), said plug ( 3 ) comprising sealing means ( 5 ); and detachable axial stop means ( 7 ) comprising an elongate plate extending transversally within the tubular element between the outer end and the plug and co-operating said axial locking means to form a stop surface to prevent removal of the plug when there is an over-pressure in the container, said stop means being introduced transversally into said tubular element through said first slot to project outside said tubular element through said second slot, wherein the plate includes a central through hole ( 10 ), and wherein the plug includes a central rod ( 11 ) projecting through the central hole in response to over-pressure in the container.
