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.

Abstract: A support for transporting containers in a microwave inspection device, including a supporting body which can be moved along a feed path and at least two receiving seats connected to the top of the supporting body to be moved along said feed path, wherein said supporting body has two or more supporting portions (S1, S2) which are at least partly separated from each other by one or more openings and each carrying at least one respective receiving seat, said supporting portions (S1, S2) being connected or integral with each other in a lower region of the supporting body.

Abstract: An inspection device for inspecting containers (100) comprises a rotary conveyor (2), provided with a plurality of receiving cavities (5), and a measuring station (400) configured to inspect each container (100) while the container (100) is being supported and moved by the conveyor (2), wherein the conveyor (2) has continuous motion and the measuring station (400) comprises a microwave detector provided with a measuring zone (410) through which each container (100) passes in order to generate an information item relating to at least one of the following: weight of the container (100) as a whole or of the dose of product contained therein, type of product inside the container (100), presence of foreign bodies in the container (100).
