ABSTRACT:
A flat blank of generally rectangular shape with rounded corners has a U-shaped incision in each end portion forming a tongue, extending endwise at each end from the portion that is to provide a tray bottom, that is separated by the incision from an end strip forming a continuous arch joining the portions that are to provide side walls for the tray. To set up the tray each end strip is folded inwards in the middle, the tongues are bent upwards and the most closely folded end strip mid-portion is pushed through a slot in the middle of the adjacent tongue, where it is held against flipping out by resilient flaps of the slot and by scollops or serrations on the upper edge of the folded-in strip bearing against the upper end of a slot. With different depths of insertion of the folded portion of the end strip through the tongue slot, different tray lengths can be provided with the same tray blank.
