Abstract
A tamper-resistant nozzle assembly for preventing the unwanted or unintentional dispensing of a material from a container. The nozzle assembly may comprise a base adapted to fit on top of a container holding the material, a mechanism located within the base and configured to provide tamper-resistant properties for the nozzle assembly, a nozzle connected to the base and having a pair of diametrically opposed tabs extending downwardly therefrom into the base, the tabs being capable of travelling radially inward when squeezed by a user, whereby, in a locked state, the mechanism limits the travel of the tabs such that (1) the nozzle cannot rotate relative to the base, and (2) the nozzle cannot be depressed to release the material from the container. When a user squeezes the tabs, the mechanism is in an unlocked state and permits the rotation of the nozzle relative to the base, to thereby enable the nozzle to be depressed relative to the base to allow it to dispense the material from the container.
