Abstract
The molded container body (10) and molded lid panel (34, 46, 48) are joined by a light and moisture impervious seal membrane (54) which fixedly adheres to the upper surface of the lid panel but peelably adheres to the upper surface of a peripheral flange (20) on the container body, thus permitting one lid portion (46) to be raised to an open position by peeling the seal membrane away from flange (20) and pulling upward, without removing the seal membrane from the lid panel.
