Container inspection arrangement for inspecting glass and/or plastic containers and a method of inspecting glass and/or plastic containers

A method of inspecting glass and/or plastic containers using a container inspection arrangement, said method comprising:

• transporting a container using a transport arrangement along a transport path to an inspection area;
• illuminating the container using at least one illumination unit;
• transmitting a portion of the light that illuminates the container through a hollow body, which hollow body is rotatable about a central axis thereof using a drive unit connected thereto, and which hollow body is disposed at said inspection area such that said hollow body is nearer a bottom of the container than a mouth of the container;
• transmitting the portion of the light to an optical structure, which optical structure is mounted in a stationary manner within said hollow body such that said optical structure does not move with said hollow body upon rotation of said hollow body;
• receiving the portion of the light using at least one camera, and thereby obtaining images of at least a portion of the container, as viewed from the bottom of the container toward the mouth of the container;
• detecting at least one of:
• the inner surface of the container, the position of the mouth of the container, the geometry of the mouth of the container, and the symmetry of the container;
• and
• said at least one illumination unit comprises a ring-shaped light disposed inside said hollow body.
