Abstract
The present invention discloses various one piece, flip style, injection molded, pour spout type closures. Each closure includes a frame having an aperture therethrough with a door hinged along a bottom edge of the aperture for opening and closing the aperture. Side panels are attached to the door and extend between the door and the side edges of the panel to form the pour spout when the door is in the opened position. Two embodiments of the present invention provide hinged side panels which fold up to help seal the closure and provide a substantially flat panel with the door in the closed position. Another embodiment of the present invention provides fixed side panels adapted to extend through the aperture and including stop members to limit the outward movement of the door to the fully opened position.
