Title:
METHOD AND APPARATUS FOR QUALITY OF SEAL AND PACKAGE INTEGRITY TESTING
Document Type and Number:
WIPO Patent Application WO/2012/012308
Kind Code:
A3
Abstract:
Testing methods and equipment are provided for fast, non-destructive testing of the quality of seal and/or integrity of a package. According to certain embodiments, dynamic impact characterization is used to determine whether a loss of pressure due to a leak in the package occurs. The methods and equipment can be used in-line with product packaging processes. According to one embodiment, an initial pressure is applied to a package under test. A region of the package is impacted with a force sufficient to create a disturbance to the package while not destroying the package by using an impacting rod. Force sensors/transducers in contact with the package and spaced a distance away from the impact region of the package detect a force signature from the impact. The existence of a leak is determined by evaluating the force signature.
