Abstract
The invention relates to a cap for containers intended for the keeping of pressurized contents. The cap has two parts, joined along a tearing indication. The two parts along their lower edge zones, are bridged by a disc of gastight aluminum foil, adapted so that it is torn up along an annular rupture line when the cap is opened.
