ABSTRACT:
Leak detector for use in detecting defective flange-shaped seals between lid and body portions of a package. A pressure chamber is provided for isolating the external edge of the seal and applying test pressure thereto. Containment of the pressure chamber includes sealing pressure applied mechanically to the flange-shaped package seal during testing, but this sealing pressure does not affect seal testing because it is appropriately limited by a self-compensating biasing of the mechanical seal. Also disclosed is a leak testing method that involves directing gas over a flexible lid at sufficiently high velocity to lift the lid at gross defects in a seal and inject gas through the gross defects. Also disclosed is a package design that employs channels to direct gas into a seal region.
