Embodiment Construction

[0014] The leak test device comprises a membrane 4, a mucous membrane 3 and a reinforcing element 5, forming a test leak. The membrane 4 and the mucous membrane 3 are circular with equal outer diameters. Said membrane 4 is situated above said mucosa 3 and is fixedly connected to said mucosa 3 in the marginal portion of the mucosa. In an area concentric with the center of the membrane 4 and surrounding the mucosa 3 , the membrane 4 is not connected to the mucosa 3 , forming a cavity 1 with the mucosa 3 . In the center of said membrane 4 there is a leak point 2 which is a small hole with a diameter of less than 1 mm. The leak point 2 provides a channel leading to the cavity 1, so that the test gas in the cavity 1 can leak out through the leak point 2 and can be detected by a leak testing system. In the region of the outer edge of the cavity 1 , the stiffening element 5 is placed therein in the form of a ring separating the membrane 4 from the mucous membrane 3 , so that a stab...

Abstract

An improved leakage testing device for attachment to a flexible wall of an item to be tested is provided with a film (4) that limits a hollow chamber (1) on the outer side of the item to be tested and with a leakage point (2), said film (4) being designed to adhere to the item to be tested.

Description

technical field [0001] The invention relates to a leakage testing device attached to the outside of a measured object. Background technique [0002] Leak testing is used to detect and calibrate leak test systems used to test the airtightness of the object under test. Typically, the measured object is food packaging, pharmaceutical packaging or packaging of aseptic objects in the medical field. Leak testing is used to detect leaks in packaging that may cause damage to the packaged product. The object whose airtightness is tested has thin walls forming the packaging of the product. The leak test is performed in an automated manner by using a leak test system. Considering that even small leaks in the test object can cause damage to the packaged product, the leak testing system must be able to reliably detect small leaks. Said leak test system shall be regularly tested and calibrated if necessary. For this purpose, the test leak is performed on the outside of the test objec...
