Method and apparatus for testing the tightness of a container (1) closed by a membrane (2), the method comprising the steps of detecting a first profile (N1) of the membrane (2) when container and membrane are in an initial force condition, modifying the initial force condition submitting the container (1) and/or the membrane (2) to a deforming action such as to induce a deformation of the membrane (2), interrupting the deforming action so as to restore the initial force condition, detecting a second profile (N2) of the membrane (2) after the deforming action has been interrupted, comparing the first profile (N1) with the second profile (N2) and identifying whether the first profile (N1) differs from the second profile (N2) by an amount equal to or greater than a predefined threshold, in order to verify whether the tightness of the container (1) is defective.
