ABSTRACT:
An airtight closing cover is produced which can be reused many times, is deformable, is corrosion-resistant and is easily accessible to the point of a screwdriver, by covering a metal ring 7 with a sheath 15 in a resilient synthetic material and a peripheral shoulder 16 which, in the closed position, is crushed by the cover (9) against a folded back rim (13) of the ring (7) and therefore comprises a barrier to possible corrosive vapors. (FIG. 1).
