A toggle-action dispensing closure for a container is provided for manipulation between a closed, non-dispensing orientation and an open, dispensing orientation. The closure includes an actuator pivotally mounted along a tilting axis on a body secured to the container. The actuator is tiltable by applying force to the actuator on one side of the tilting axis so as to move the actuator from a non-dispensing position to a dispensing position. The actuator includes a flange having an engagable surface. The closure body includes an annular wall in which the actuator is received, and the annular wall includes an inwardly projecting interference member which underlies the actuator engagable surface and prevents tilting of the actuator unless a sufficient predetermined, initial opening force is exerted on the actuator to cause permanent, plastic deformation of the engagable surface is and/or interference member. Thereafter, the actuator can be tilted to the open dispensing position a second or subsequent times in response to subjecting the actuator to a force less than the predetermined, initial opening force.
A spray actuator for a pressurized aerosol canister that simplifies the mechanical moving parts of a spray actuator to a body and a trigger and a third nozzle piece being inserted at the very end of the product dispensing passage either in the body or the trigger. The moveable trigger rotates about a pivot or hinge point on the body and is biased by engagement with the valve stem or an additional spring return into a neutral unactuated position where the product is not dispensed. When dispensing of the product is desired, the user grasps the actuator and pulls the trigger against the body and overcomes the bias of the valve stem and the valve is actuated as discussed above to dispense the pressurized aerosol product.
