Abstract
An easy set-up tray wherein in addition to the usual well defined by a tray for receiving food products, there is a top panel for receiving other products, including containers for drinks and the like. Each tray is of a one-piece construction and is provided in a substantially flat knocked-down state. When it is desired to erect or set-up the tray, side panels thereof are grasped and pulled apart with the result that the tray automatically erects and is locked in its erected or set-up position. The top panel is connected to the side panels by reversely foldable connecting panels so as to provide for a rigid structure.
