The present disclosure also provides a plug that may be functionally integrated into the container and further provides a packaging with a plurality of such containers.
Claims23
A pressurized gas container comprising:
- a container body, defining a pressurized gas enclosure and a neck integral therewith having an end portion that is configured for coupling with a coupling element and is fitted with a plug;
- the plug being formed with a bore that is fitted with a barrier element that forms a gas impermeable barrier that seals said enclosure;
- said barrier element being a rupturable or pierceable metal sheet configured for non-reversible rupturing or piercing by a shaft of a gas-channeling member of said coupling element;
- and having
- one or more sealing elements, distinct from said barrier element and configured for forming a gas-tight association with said shaft.

13-14. (canceled)
A method for the manufacture of a container with a pressurized gas, comprising:
- (a) providing a container blank configured to hold pressurized gas, the container blank having a container body, defining a pressurized gas enclosure, and a neck at its upper end, the neck having an upper, open end portion, at least said upper end portion being formable under defined conditions;
- (b) introducing pressurized gas into said enclosure through said open end;
- (c) while maintaining gas pressure, introducing a plug device into said open end, the plug device comprising external side walls and a bore formed within it, the bore being fitted with a rupturable or pierceable metal sheet barrier element configured for non-reversible rupturing by a shaft of a gas-channeling member of a coupling element of a device or system, and comprising one or more sealing elements within said bore distinct from said barrier element and configured for forming a gas-tight association with said member;
- and
- (d) tightly affixing said plug device within said neck by forming said upper end to tightly engage the plug device's external faces.
