Abstract: A power assembly for dispensing product from a container includes a pump mechanism and an energy storage mechanism. The pump mechanism includes a rotatable actuating collar connected through an escapement mechanism with a drive screw with an externally threaded shaft engaged with internal threads in a piston. Rotation of the collar reciprocates the piston to store energy in the energy storage mechanism and to draw product into a pump chamber from which the product is dispensed. An actuator is connected with a stem valve to open it when the actuator is depressed, enabling the energy storage mechanism to push the piston back to its at-rest position to force product from the pump chamber and ready it for another dispensing cycle. Disengagement of the escapement mechanism when the actuator is depressed prevents rotation of the actuating collar. Different energy storage mechanisms can be interchangeably attached to the pump mechanism.

Abstract: A mechanically pressurized aerosol dispensing system comprising a cap which houses a piston, an actuator moveably attached to the cap, forming together with the cap a dispensing head assembly, and an expandable elastic reservoir. The system is fitted over a standard container holding a liquid product, and includes a dip tube assembly to draw liquid into the dispensing head assembly, where the contents are released through the dispensing head assembly, via the aerosol nozzle and valve. A twist of the threaded cap raises a piston, thereby opening a charging chamber within the dispensing head assembly. This creates a vacuum with the resulting suction pulling the product up through the dip tube to fill the charging chamber. Twisting the cap in the opposite direction lowers the piston in a downstroke which closes the charging chamber, forcing the product into the expandable elastic reservoir where it is then discharged through the nozzle.
