摘要 PCT No. PCT/EP96/02967 Sec. 371 Date Jan. 6, 1998 Sec. 102(e) Date Jan. 6, 1998 PCT Filed Jul. 5, 1996 PCT Pub. No. WO97/03343 PCT Pub. Date Jan. 30, 1997For the purpose of testing deformable containers (2) for tightness, a negative pressure is generated in the container (2) and the internal pressure is then measured. The negative pressure is generated by deformation of the container (2). A sealing strip (6) is set on the container opening (8) in order to maintain the negative pressure in the container (2). In non-tight containers, the pressure increases relatively rapidly again to the ambient pressure.
