PERFECTIONNEMENT AUX CONTENANTS HERMETIQUES DESTINES A CONTENIR UNE BOISSON GAZEUSE

摘要

The container i.e. bottle (1) has an opening (10) bounded by a periphery (12) and equipped with a removable exterior cover (6) for sealing the opening. A removable inner sealing membrane (11) closes the opening, where the sealing membrane is permeable to gases and impermeable to liquids. The outer cover and the inner sealing membrane are removable successively and independently of each other during the opening of the bottle, where the sealing membrane prevents unintended exit of liquid from gas expansion upon removal of the cover.
