ABSTRACT:
A pop-up display comprises a generally box like hollow member having an open end at the top thereof and a pivotal flap or flaps for opening and closing the open end thereof. A spring biased pop-up display includes a first coil spring which is disposed on a first axis and held in a compressed position by at least one of the flaps when the flap or flaps are in a closed position. A strap or thread is stretched across the flaps to hold the flaps in a closed position. The spring biased pop-up display includes a pleated paper banner having opposite ends with a second coil spring disposed between the opposite ends and with its axis essentially perpendicular to the axis of the first spring. A candle or sparkler engages the flap or thread and upon ignition burns through the strap or thread. When the strap or thread is broken the first spring pushes the display upwardly to thereby allow the second spring to expand the pleated paper banner outwardly beyond the confines of the hollow chamber.
