Abstract: An inspection device for inspecting containers with the container closures arranged thereon, has a lighting device which illuminates the containers to be inspected and an image recording device which is configured for recording spatially resolved images of the containers. The



image recording device is at least also aligned with regions of the containers which are arranged in a longitudinal direction of the container below the container closures arranged on the containers, and an evaluation device is provided which is configured to, from at least one image recorded of the container provided with the marking, a relative rotational position of this container with respect to the container closure arranged on the container.

Abstract: The disclosure relates to a method for optically inspecting containers, wherein the containers are transported to an inspection unit with an illumination unit and with a camera, wherein the illumination unit emits light from a flat light-emitting surface, wherein the light is transmitted or reflected via the containers, wherein the camera captures a respective at least one of the containers and the light transmitted or reflected via same in at least one camera image, and wherein the at least one camera image is analysed by an image processing unit for intensity information in order to identify foreign bodies and/or defects in the container.

Abstract: The present disclosure relates to an apparatus for optically inspecting a pulp bottle. The apparatus comprises a lighting device having an opening, wherein a mouth of the pulp bottle can be arranged below the opening of the lighting device; and a camera which is configured to take an image of at least a part of an inner wall of the pulp bottle through the opening of the lighting device or from the opening of the lighting device, wherein the pulp bottle can be arranged such that the part of the inner wall of the pulp bottle is illuminated by the lighting device. The present disclosure further provides a method for optically inspecting a pulp container, in particular a pulp bottle.

Abstract: An apparatus for inspecting containers and in particular cans, having an illumination device which illuminates the can to be inspected and radiates radiation onto an inner base wall of the container, and having an image recording device which records at least one spatially resolved image of the inner base wall illuminated by the illumination device is provided. The apparatus has a first polarization device in a beam path between a light source of the illumination device and the inner base wall in such a way that the radiation reaching the inner base wall is polarized, wherein the illumination device being designed in such a way that a predominant proportion of the radiation irradiated into the container by the illumination device reaches the inner base wall.
