    摘要： 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).

    摘要： The invention relates to a pressure relief valve for a packaging container (3), comprising a base body (4) with at least one through opening (9, 29), a sealing surface (14) and a peripheral region (18), wherein the peripheral region (18) may be sealably connected to an inner surface (3a) of the packaging container (3), the sealing surface (14) having an inwardly tapering form and a flexible membrane (6), in contact with the sealing surface (14) of the base body (4) to generate a sealing effect. The membrane (6) covers the through opening (9), a fluid (5) is arranged between the sealing surface (14) and the membrane (6), wherein a recess (10) is formed in the base body (4) to accommodate thee membrane (6). The recess (10) has a first diameter (D1), between 70 and 80% of a total diameter (D2) of the base body (4).

    摘要： A device (10) for checking the tightness of air evacuated packing containers (1), comprising a bell-shaped housing (31) with a distance sensor (20) that is connected to a partial vacuum source (23). The distance sensor (20) and a pressure sensor (25) send their signals (U, P) in the form of input values to a control device (23) which combines both signals (U, P). The control methods which can be implemented with the inventive device (10) make it possible to determine if the packing container (1) is tight and indicate the pressure inside (Pi) in each packing container.

    摘要： The invention relates to a pressure relief valve for a packaging container (3), comprising a base body (4) with a central through opening (9), a sealing surface (14) and a peripheral region (18), wherein the peripheral region (18) may be sealingly connected to an inner side (3a) of the packaging container (3) and the sealing surface (14) has an inwardly tapering form and a membrane (6), making contact with the sealing surface (14) to permit a seal wherein a fluid (5) is arranged between the sealing surface (14) and the membrane (6). The membrane (6) is flexible and a recess (30) is made in the base body (4) into which the central through opening (9) opens out, wherein in the opening region of the central through opening (9), an annular bead (12) projecting in the direction of the membrane (6) is arranged, projecting into the recess (30).
