ABSTRACT:
The device permits of compressing a rubber ring (4) between the mouth of a glass jar (1) and its glass lid (2), and comprises a collar (5) that is secured initially to the lid, whereupon the lid and collar are offered to the jar; a lip (6), integral with the collar, hooks under a rim (7) afforded by the neck of the jar, and the lid is then tightened by pulling down on a lever (9) hinged to a pair of lugs (8), likewise integral with the collar. The collar also incorporates a skirt (18) that conceals the area of contact between the lid, the rubber ring and the mouth of the jar.
