Abstract
Abstract A child-resistant nozzle connectable to a spray dispensing device. The child-resistant nozzle assembly of the present invention includes a nozzle having a slot in the upstream end for receipt of a lug connected to the pump body. The lug may be depressed by the fingers of the user to selectively engage or disengage the slot in the nozzle. When the lug is engaged in the slot in the nozzle, no liquids can leak or be dispensed from the nozzle.
