Superimposable latticed trays, particularly for the support of flat objects for the purpose of treating them in a conditioning enclosure. According to the invention these trays each comprise a bottom 2 constituted by a light lattice of thin wires 9, 10 forming an open-work support structure, and a flat band 3 surrounding the bottom or extending along at least two lateral opposite and parallel sides 4, 5, the band being associated with cross-pieces 6 disposed under the lateral sides of the band perpendicularly to the latter in such a way as to form between two superimposed trays a space substantially equal to the height of these cross-pieces while each tray is supported on the lateral sides of the one located below it by the intermediary of the cross-pieces, the lattice bottom of each tray being formed from successive adjacent parts 2a, 2b, 2c, 2d, 2e, 2f inclined with respect to the horizontal plane and alternately having a slope in the opposite direction. Application to supports for flat objects such as plastic bags containing blood to be dehydrated. <IMAGE>
