Abstract: A container or bottle with a cap for resealing where the seal is produced between the upper lip and, if needed, the lateral lip of the container while the interior closing surface of the cap is provided with a sealing mass which can be deformed within limits and which, after opening and resealing of the container with the cap can be deformed to allow venting from the interior of the container by the provision of a depression formed on the lip of the container and into which the sealing mass will extend to effect sealing but which, after opening, and repositioning of the cap relative to the container, will affect only partial sealing of the container.

Abstract: A deep-drawn screw cap of aluminum for glass bottles under internal pressure, where the transition area between the upper end face 1 to the lateral thread face 2 up to now was always evenly deep-drawn, now is to have at least one undeformed partial area 8. Because of this, sealing against the lateral edge 7 of the mouth is partially disrupted and a chance for the escape of gas is purposely provided in case the internal pressure in the glass bottle should rise too high. If required, a plurality of such partial areas 8 may be provided. In the deep-drawing device for a sealing head for the production of such screw caps the inner recess 12 should provide at least one partial enlargement 14 oriented towards the center axis 13 and extending approximately to the diameter of the preceding recess 11.
