Dismantleable and sealed connection device and applications of this device, especially for fastening the cover of a container

摘要

The dismantleable and sealed connection of two components such as a stopper 28 and a container 26 is produced by providing, on the outer surface of the stopper, two adjacent grooves 40 between which an O-ring 38 may roll. This rolling is obtained by the interaction of the O-ring 38 with a circumferential outgrowth 37 formed on the inner surface of the opening 34 of the container 26 when a force is exerted in one direction or the other along the axis of the opening. <IMAGE>
