U-shaped light-tight structure

摘要

A closure of a container and more particularly a removable light-tight door. The door includes a plane surface and sides having two partitions and each orientated at 90 DEG with respect to the plane surface. The outer partition of the edge is obtained by folding the wall and the inner partition consists of an attached folded panel with four elements, spot welded. The sides of the door form a U which comes to cooperate with the U formed by the sides of the container. Guide elements are provided in at least two corners of the door.
