Abstract
The invention concerns an inner tray, arranged inside a chamber, comprising a plurality of parallel beams (1), located in a common horizontal plane and fixed through their ends to the wall of the chamber, and, between said beams and supported thereby, rows of adjacent rectangular plates (2), completely covering the space between the beams. The invention is characterized in that the supporting edges (3) of the plates (2) through which the latter are supported on the beams (1), are folded downwards by two substantially right-angled folds, and in that each of the edges (4) of the plates (2), perpendicular to the beams (1) is folded so as to form a female part (4a) or a male part (4b) capable of being respectively nested in a male (4b) or female (4a) part formed by the folded edge of the adjacent plate. The invention also concerns a chamber containing such a tray.
