Abstract

993,457. Trays. BOWATER RESEARCH & DEVELOPMENT CO. Ltd. March 9, 1964, No. 9836/64. Heading B8P. An open topped stackable tray has a pair of opposed side walls 6, 7 each having at least two layers provided by folding a panel over upon itself with the fold uppermost, the inner layers 12 having a plurality of vertical spaced slots 21 arranged in opposed pairs extending to and into the zone of the fold 11 between the layers. In the form shown the tray is erected from a single blank (Fig. 1) by bringing into perpendicular relationship with the base, end panels 30, 31 folding in flaps 35 and folding inwardly flaps 36 to lie flat against the end panels 30, 31. The side panels 6, 7 are then folded up so that the outer layers 10 lie outside and against the side extension flaps 35 and the inner layers 12 over the flaps 35, the base flaps 13 extending from the inner wall panel 12 being brought simultaneously to lie flush against the base panel 1 to abut each other. The tray may be strengthened by taping the four corners (Fig. 2). In a further embodiment (Fig. 3) a separate blank, comprising a base panel 50 with side panels 52 consisting of inner layer panels 54 with slots 56 and outer layer panels 55, may be folded and placed in a box so that the panel 50 engages the base and the panels 55 the sides. The slots may be stopped short of the base panel so that, when printed circuits are stored, they do not make contact with the base. The outlet box may be provided with handles.
