  • Clip mounted aerosol dispenser actuator
    Patent number: 3967763
    Abstract: An actuator for a pressurized aerosol dispenser includes passages which lead from the container mounted valve to a discharge orifice. The actuator provides a lever action having a mechanical advantage to reduce the finger applied force required to open the valve. The pivot or fulcrum of the actuator is in the form of a generally U-shaped resilient clip which grips and rides on the mounting cup bead.

  • Dispensing pump
    Patent number: 3949910
    Abstract: An inexpensive, container mounted, plastic dispenser pump for dispensing a product from the container is leak-proof in its rest position since neither the outlet valve nor the atmospheric container vent open in response to container pressure or positional attitude of the dispenser. The outlet valve is positive in action since it is opened by relative movement of pump parts during actuation. The pump inlet valve is actuated by differential pressure. The atmospheric vent for the container is blocked by the position of pump parts when at rest.
