1. A surface decontamination device (1) for decontaminating outer packaging (2) which contains pre-sterilized consumer goods, and which has a circumferential collar (3) prior to transfer into an isolator, said surface decontamination device (1) comprising conveying means for conveying the outer packaging (2) in a conveying direction (F) along a conveying path from an inlet side of the surface decontamination device to an outlet side of the surface decontamination device (1), the conveying path passing through a decontamination chamber (5) which is disposed between the inlet side and the outlet side and to which a radiation source (6), is assigned for irradiating the outer packaging (2) which can be conveyed through the decontamination chamber (5), and through at least one lock chamber (8) which is disposed between the inlet side and the outlet side and which is adjacent to the decontamination chamber (5) and which has an inlet and an outlet, said inlet and outlet being able to be opened and closed by closing means, the conveying means comprising a suspension transport device (7) disposed in the decontamination chamber (5) for suspended transport of the outer packaging (2) by its circumferential collar (3),
wherein
the closing means comprise a circumferential wall (9, 17) which can be rotated about an axis of rotation and which has solely one opening which can be displaced into the conveying path for conveying the outer packaging (2) through said circumferential wall (9, 17) which is realized in such a manner that the inlet and the outlet can be opened solely in an alternating manner, a lifting device (11, 15) for an automatic, vertical displacement of the outer packaging (2) relative to the suspension transport device (7) being disposed in the at least one lock chamber (8, 14).
