A device (7) for checking the seal tightness of deep-drawn, blown plastic parts (5) forming an inner cavity (10), especially containers for food such as yogurt, curd cheese, cheese, salad or similar, comprises a first and second testing bell (8, 9), the first testing bell (8) sealingly covering the inner cavity (10) of the plastic part (5) in the testing position and the second testing bell (9) sealingly covering the plastic part (5) on the outside (8) in the testing position. A connection (13) for allowing gas to enter or leave is allocated to one testing bell (8; 9) while a flow-measuring device (15) is allocated to the other (9; 8). |
