ABSTRACT:
A system and method for determining the integrity of a sealed container closure assembly wherein the closure is secured to the container by a force applying member and the integrity is determined by converting the force used to secure the closure into a force signal and comparing the force signal to a reference signal, which is reflective of the force used during a closure operation which resulted in seal integrity. The force signal which comprises a series of electrical signals is compared to a series of corresponding reference signals or is a single signal compared to a reference signal at a plurality of points during the closure operation. An indicator is used to indicate when a preselected number of acceptable or non-acceptable comparisons are reached.
