FILM CAMERA WITH HOLDING PROFILE Russian patent published in 2019 - IPC G01M3/32 

FIELD: physics.

SUBSTANCE: invention relates to devices for testing devices for tightness. Essence: film chamber (12) for placement of test object (18) to be tested for presence of leakage has at least two film layers (14, 16) and at least two frame elements (24, 26). Each frame element (24, 26) has sealing surface for gas-tight application of both frame elements (24, 26) to each other for tight closing of film chamber (12). Each of film layers (14, 16) in edge area has at least one retaining profile (20). Each of frame elements (24, 26) has in its sealing surface at least one retaining groove to receive retaining profile (20) so that both film layers (14, 16) are held between both frame elements (24, 26) by means of connection with geometrical closure.

EFFECT: technical result is creation of film chamber with improved attachment of film layers.
