Abstract:
PCT No. PCT/DE96/00402 Sec. 371 Date Nov. 24, 1996 Sec. 102(e) Date Nov. 27, 1996 PCT Filed Mar. 7, 1996 PCT Pub. No. WO96/30280 PCT Pub. Date Oct. 3, 1996An overpressure valve for a packaging container which includes a base plate with a central valve hole that coincides with a hole in a wall of the container and a valve diaphragm. The valve diaphragm covers the valve hole and the adjoining zones and includes two parallel peripheral zones which form a channel along an adhesive-free middle zone. To keep the opening pressure of the overpressure valve slight and to simplify the manufacture of the tool for the valve hole, the valve hole is formed of two intersecting circular holes which extend longitudinally of the adhesive-free middle zone of the valve diaphragm.
