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 or panel of the body portion, and, in its folded position, all edges of the locking flap are flush with the adjacent surface of the panel. One or more dispensing openings are provided in the panel and sealing means are provided on the bottom of the flap to close the dispensing openings in the folded position of the locking flap. Two distinct sets of cooperating locking surfaces are provided on the flap and body portion to retain the locking flap in its folded position. The one set requires a vertically downward pressure on a specific area on the panel to release. The second set of latching surfaces can then be released by manual inward depression of a segment of the annular wall of the body member. Such concurrent application of a downward force and a compressing force on the closure effects an elevation of the free edge of the locking flap above the conforming recess to permit the locking flap to be manually lifted to a fully opened position.
