Abstract (en)
[origin: WO2006034950A1] The invention relates to a pressure relief valve (10; 50; 60; 65; 66), comprising a base body (11; 67; 68), which is covered by a valve membrane (40; 59). The base body (11; 67; 68), which is located on the inner face (2) of a packaging container, permits the escape of excess pressure from the packaging container into the atmosphere by means of passages (23; 24) and perforations (5) that are configured in the wall (1) of the packaging material. The inventive pressure relief valve (10; 50; 60; 65; 66) thus responds particularly well, i.e. allowing particularly low opening pressures, by means of the special configuration of its base area (15; 55; 67; 68).
