US Patent 7686193 Mechanical actuator for aerosol can

A mechanical actuator for attachment to a conventional aerosol can to allow for holding the can with a comfortable handle and controlled dispensing of substances, such as spray paint, using a trigger-type actuator. The device further includes a quick can loading and unloading system including a resilient band that facilitates rapid hands free unloading and one hand loading of aerosol cans. A manual actuator is provided to selectively stretch the band to facilitate loading (and unloading) of aerosol cans. Relaxing the manual actuator allows the resilient band move into constricted engagement with the can.
