Abstract

A device for inspecting filled and sealed containers consisting of a first carousel in which the containers to be inspected can be rotated about their longitudinal axis so that the contents in the containers begin to rotate with sufficient speed to stir up any foreign bodies that may be present from the bottom of the container and consisting of a second carousel following the first carousel in the direction of transport for bottom-free transport of the containers, at least one inspection device which operates by the dark field method being provided for detection of light scattering foreign bodies in the contents, whereby the two carousels are arranged side by side with their partial circles in tangent so that the containers can be transferred from the first carousel directly to the second carousel.
