The container has a rigid frame formed by superposition of lower and upper rectangular frames (19, 20) enclosing between them the edges of a bottom element (21) so that the element forms a recess for housing an instrument. The bottom element is made of disposable material such as paper or cloth, translucent to X-rays. The lower frame comprises support arches (23) at its each longitudinal end. The recess is closed by a vertical wall (24) forming a space between the lower frame and the corresponding arch. |
