Abstract
Abstract An overcap for use on dispensing containers which cap offers resistance to attempts by a child to dispense the contents from the container is disclosed. The overcap features an actuator mounted on the container dispensing stem, an outer shell which encloses the actuator and a U-shaped communicator which movably contacts, at its bottom end, the actuator and which has a portion of each vertical leg protruding through apertures in the outer shell. Pressing downward on both of the protruding legs simultaneously will depress the actuator and cause the contents of the container to be dispensed. Application of downward pressure on only one of the protruding legs will not result in depression of the actuator but rather only partial rotation of the communicator on the top of the actuator.
