ABSTRACT:
A one-piece molded thermoplastic child-resistent dispensing closure in which the dispensing opening in the closure is sealed by the downwardly extending projection of a locking flap that is foldably attached to an edge of the closure, in which the top of the closure comprises a recess to receive the sealing flap when it is in its closing position and in which the portion of the recess which is adjacent the free end of the locking flap is deeper than the thickness of the locking flap so that the free end of the locking flap can be depressed within the recess to facilitate the opening of the closure. Certain embodiments are described in which the locking flap is provided with a downwardly depending tab which is received in a recess in the skirt of the closure when the locking flap is in the closed position and which is deflected outwardly from the recess by the depression of the locking flap into the recess in the top of the closure to further facilitate the opening of the closure.
