  • Leak detection device for in-line measurement of package integrity
    Patent number: 5029463
    Abstract: A leak detecting device for a package having a plastic cover. Before sealing the cover, a gas containing five percent helium is introduced into the package. The package is placed beneath a hood which has an aspiration device to move the air within the hood through a pipe. A helium sensor is placed within the pipe to detect helium which leaks from the package. The hood also carries a plate which is spring mounted and which comes into contact with the package lid as the hood is lowered over the package. This causes additional pressure within the package so as to accelerate the detection of any leak.
