Claim Text:
1. An apparatus for permitting inspection of container processing, said apparatus comprising a lip seal, a first structure, a second structure, and a transition between said first structure and said second structure, wherein said lip seal seals said transition, wherein said lip seal is produced in one piece, wherein said lip seal is made from an elastic material, wherein, in an un-deformed state thereof, said lip-seal has an at least partially sickle-shaped cross-section, wherein said lip seal comprises a strip-shaped first lip-section, wherein said first lip-section extends outward to a first edge, wherein said lip seal has a strip-shaped second lip-section, wherein said second lip-section extends outward to a second edge, wherein said second edge is a sealing edge, wherein a thickness of said second lip-section decreases towards said sealing edge, wherein, in said undeformed state, said first lip-section and said second lip-section are curved around an axis oriented along a longitudinal direction of said lip seal, wherein said lip seal comprises a first surface, wherein said first lip-section defines a concave curve along said first surface, wherein said second lip-section defines a convex curve along said first surface, wherein said first structure is selected from the group consisting of an aperture frame and a mounting frame, wherein said second structure is selected from the group consisting of an aperture closure and a viewing window, and a viewing window of a clean chamber for treatment of a container, wherein treatment of a container is selected from the group consisting of sterile treatment of said container and aseptic treatment of said container, and wherein said elastic material is selected from the group consisting of a rubber-elastic material, permanently elastic material, a rubber-elastic, permanently elastic plastic, and silicone.
