Seal for container with two-part cover - has cross-web with top seal, screwed to parts for covering joints

摘要

The container has two or more cover parts (14, 15) for a single aperture with common sealing surface. The cover parts are screwed gas-tightly to the sealing surface. A cross web (19) is loosely inserted into the opening, in the joint (17) between two neighbouring parts. The top of each cross web has groove-like spaces (21) for an elastically deformable sealing element. The depth of the space is less than the thickness of the seal. ADVANTAGE - Gas-proof sealing of joints between parts of cover.
