Abstract: An electrically-powered fluid sprayer employs a piezoelectric fluid pump that includes an inlet port, an outlet port, a pump chamber, and a piezoelectric element that is deformed and displaced by electrical signals supplied thereto to vary the volume of the pump chamber. Such displacement pumps fluid into the inlet port and into the pump chamber and discharges fluid from the pump chamber out the outlet port. The inlet port is in fluid communication with a fluid reservoir. Spin mechanics may be disposed downstream from the outlet port of the fluid pump and upstream from the discharge nozzle. The piezoelectric fluid sprayer may be extended to include a dual chamber piezoelectric pump that pumps different fluids (e.g., a liquid and air). The output of the dual chamber pump is mixed in a manifold and supplied downstream to the discharge nozzle. Spin mechanics may be employed in the fluid stream upstream from the discharge nozzle after the mixing.

Abstract: A container closure system including a container cap and a container closure may be frictionally mated such that projections in the container closure removably lock interior projections of an opening in the container cap in spaces defined in the container closure projections to hold the container cap on the container closure.

Abstract: A trigger actuated liquid sprayer, including a pump body, a discharge nozzle mounted on a forward end of the body for manual rotation about a central axis thereof between discharge open and closed positions, and a trigger lever movably mounted to the body for operating a pumping mechanism upon actuation thereof. A trigger cover may be mounted on the sprayer and overlie a front face of the trigger lever in a first position for immobilizing trigger lever actuation. The trigger cover may be rotatable to a second position from the first position for exposing the front face for facilitating a grasp of the trigger lever for manual actuation thereof for operating the pumping mechanism. The trigger cover may be latched with the trigger lever in the first position to prevent rotation of the trigger cover from the first position to thereby render the sprayer child-resistant.

Abstract: A trigger actuated pump sprayer has a lock bar connected to its nozzle cap or foamer cap for rotation therewith for both locking the trigger lever against actuation and for locking the nozzle cap against rotation from a discharge closed position, the lock bar having a bendable tab for coupling the lock bar to the trigger lever to prevent nozzle rotation in either direction of rotation.

Abstract: The dispensing system for a remote operation includes a trigger sprayer assembly removably mounted to a container of liquid to be sprayed, the assembly being mounted within a cutout section provided at the upper end of the container as part of a through opening forming the carrying handle of the container. The trigger sprayer assembly has a flexible delivery tube which may be coiled and stored within a hollow gripper handle provided on the trigger sprayer, and may extend outwardly from the gripper handle to function as a resilient element for mounting the trigger sprayer in place. A one-piece adaptor is non-removably connected to a distal end of the delivery tube and connects to the container by mounting directly to an external dip tube of the container or by mounting in a closure cap of the container.
