Date Jan. 30, 1986.A device for testing containers as to leakage and defects is comprised of a container sealing portion (4), a pressure exerting portion, and a pressure gauge (8). Said pressure exerting portion is provided in the shape of a piston/cylinder system (2, 3) that is maintained in an extended position by a tensioning means, e.g. a spring (5). Said container sealing portion (4) is provided either on the piston (2) or on the cylinder (3) for sealing contact with the container opening. The chamber between the cylinder (3) and the piston (2) is in communication with the pressure gauge (8) and, via a channel (13) in the container sealing portion (4), with the interior of the container (1). The device may, furthermore, be provided with a feeler means (12-19) for testing the container as to moulding films and the like.
