Abstract
The invention relates to a process for manufacture of a top 1 intended to be attached on a container or a flexible tube 50 and comprising a neck 3 the opening 7 of which is connected by a tearable ring-shaped part 10 to a cover 20 serving as an impervious stopper prior to breaking of the ring-shaped part and then being able to serve for recapping. The cover 20 is extended by a plate 30 the periphery 31 of which has a common axis of symmetry with the tearable ring-shaped part 10 and is provided with at least three lugs 32. The skirt 40 is open at one end; its inner surface 46 is partially cylindrical, its section following the exact shape of the periphery 31, except for the lugs, of the plate 30, and is provided with at least three cavities 41 intended to accommodate said lugs. The skirt is drawn around the plate 30 to the point of immobilization, brought about by the insertion of the lugs 32 on the plate 30 into the cavities 41 of the skirt 40.
