Abstract (en)
[origin: WO0107334A1] The invention relates to a screw-type cap (19) having a sealing lip (19) with a base part (29) placed laterally in at least one thin part of the cap bottom (3). Whenever the cap bottom (3) bulges as a result of excess pressure in the bottle (13), the end of said sealing lip is pulled outwardly and said base part (29) is pulled inwardly. Tilting of the sealing lip (19) over the contact area in the neck (11) reduces the pressure force applied by the cap membrane (37) on said neck (11) and allows for a reduction of the excess pressure.
