Resealable gas impermeable sealing assembly |
摘要 |
Larger gas tight containers for products such as carbonated or pressurised drinks require a resealable sealing assembly. The gas leakage through the assembly in its ex-factory sealing condition determines the shelf-life of the product. The present assembly provides a foil (8) across a neck (10) of the bottle. The foil is supported in the ex-factory sealing condition by a plate (4) of a plug (36) which depends from an over cap (4). The over cap is screwed to an outer wall of a tubular spout (6) that surrounds the neck of the bottle. In the resealed condition the plug can be screwed deeper into the neck so that a secondary seal is formed between the plate and the neck.
