ABSTRACT:
A package suitable for storing and dispensing potentially dangerous material, which is resistant to opening by children yet readily openable by adults. The package is preferably a bottle which has a body and a finish portion. The finish portion has a threaded outer end for mating with a closure. A resiliently deformable cantilevered beam is connected to the finish portion between the threaded outer end and the body of the bottle. The beam is angled outward and downward from the finish portion. The beam has a substantially vertical locking surface and a pushtab spaced along the beam. The angle of the beam is such that the pushtab may be depressed substantially radially toward the finish portion. The locking surface is located between the finish portion and the pushtab so that depression of the pushtab results in a greater beam deflection and lower deflection force at the pushtab than at the locking surface. A bottle closure has threads for rotatably securing the closure to the finish portion of the bottle. The closure also has a tooth projecting radially inward from its lower inner surface and so shaped and positioned that it will engage the locking surface of the resilient beam whenever there is an attempt to unscrew the closure. It thereby prevents removal of the closure until the pushtab is manually depressed to disengage the closure tooth from the locking surface of the cantilevered beam.
