Abstract: An actuator device for a pressurized container incorporating an internal back flow prevention valve. The actuator may include a ball and socket check valve with a resilient component to maintain the ball in a condition to operate as a check valve even when upside-down.

Abstract: A dispensing canister apparatus for controlled release of a stored fluid includes first and second thermochromic clips for providing a visual indication of the ambient air temperature; a hose member surrounding a channel and having first and second open ends, and the first open end being connected to the canister such that the channel is in fluid flow communication with the inner cavity; a control on the canister for selectively actuating the flow of the stored fluid from the inner cavity into the channel and through a coupler member at the second open end of the hose member; and wherein storage of the first thermochromic clip in the first receptacle positions the fastening member such that it obstructs movement of the control for actuating the flow of the stored fluid.
