Abstract (en)
[origin: EP0101362A1] 1. Method for sealing and opening a container/stopper assembly, the container having an opening (6), the stopper (8) and the opening (6) both having a slight conicity of the order of 1 to 2 degrees, this method comprising the following successive stages : a) a thermal disequilibrium is created between the stopper and the walls of the opening so as to cause relative expansion of the opening in relation to the stopper ; b) the stopper is inserted into the opening until it reaches a predetermined axial position which corresponds, after the thermal equilibrium has been restored, to a predetermined degree of tightness ; c) the thermal equilibrium is restored between the stopper and the opening ; d) the stopper is removed by causing renewed relative expansion between the stopper and the opening.
