<p>A flexible cover (1) is described, for sealing a container against atmospheric agents, comprising a central portion (2) equipped with grip (4) and an external crown (3), capable of being fitted onto an edge of variously sized containers, wherein the central portion (2) is adapted to be deformed by inverting its curvature direction under a concentrated load, and by keeping the same curvature direction under a distributed load. A process for using such flexible cover (1) is also described.</p> |
