Abstract
Abstract A one-piece freezing tray is provided having at least one molding compartment for forming ice cubes. The tray is comprised of a flexible material and the compartment has a horizontally disposed mouth at the uppermost end of the compartment. The compartment has integrally formed in the lowermost wall thereof a projection depending from the outer surface thereof. An ice cube is removed from the compartment by placing the projection against a hard surface and pressing the mouth towards the projection to deform the lowermost surface of the compartment which urges the ice cube out of the compartment.
