Abstract: An apparatus for checking the tightness of a closure of a container, in particular a pharmaceutical or cosmetic container, the closure comprising a closure cap for closing the container and an elastic sealing member arranged between the closure cap and a mouth edge of the container, comprising: a turntable movable relatively against the closure of the container for exerting a compressive force on the elastic sealing member to effect compression of the elastic sealing member, wherein the turntable is connected to an axially displaceable drive shaft of a drive unit, and wherein the turntable is configured to be set in rotation with the container coupled thereto; a crimping device for crimping the closure cap; a control unit for controlling the drive unit; and a position encoder for providing a value representing a stroke position of the turntable.
