Title: Safety closure

Abstract: An improved safety closure for containers of harmful products includes an inverted cup-shaped body member formed of resilient plastic material and an integrally molded locking flap connected by an integral hinge to the top periphery of the body member. The locking flap folds into a conforming recess in the top surface of the body portion and, in its folded position, all edges of the locking flap are flush with the adjacent top surface of the body portion. Dispensing openings are provided in the top wall of the body portion and sealing means are provided on the bottom wall of the flap to close the dispensing openings in the folded position of the locking flap. Cooperating latching surfaces are provided on the flap and the body portion to retain the flap in its folded position. A portion of the annular wall of the body portion is recessed so as to permit manual inward depression of a segment of the outer wall of the body portion. Such depression effects a camming action on the locking flap to force at least an edge portion of the locking flap out of flush engagement with the body portion to permit the locking flap to be manually lifted to a fully open position.
