ABSTRACT:
A method of and apparatus for the testing of containers, preferably in a filling closing machine for comestible products in plastic cups or the like. The container is received in a vacuum bell or chamber which is equipped with a suction cup at the end of a suction pipe above the cover so that, when the chamber is evacuated, the cover can bulge to block the suction cup and a pressure differential developed between the suction pipe and the chamber signalling an effective seal. In the case of an ineffective seal, damage to the cover or the like, the pressure difference does not develop and the defective package can be sorted out.
