Method and apparatus for testing the tightness of a container closed by a membrane

Abstract

A method and relative apparatus for testing the tightness of a container closed by a membrane are described. The method includes steps of: submitting the container to a deforming action to increase the pressure inside the container; submitting the membrane to an abutting action to counteract the deformation of the membrane caused by the deforming action; maintaining the action of abutting the membrane at the same time as the action of deforming the container for a set period of time; interrupting the action of abutting the membrane at the end of the period of time; detecting at least one parameter related to a membrane profile when the abutting action has ceased; and comparing the at least one parameter related to the membrane profile with a predefined threshold to verify whether the tightness of the container is to be classified as defective.
