  • Patent number: 4865228
    Abstract: A lockable fluid dispenser cap is used with a dispensing pump for dispensing a fluid product from a container. The dispenser cap includes a container closure, locking fingers mounted to the closure, a lock actuating member rotatably mounted to the closure, and a pump actuating member coupled to the lock actuating member. The closure mounts the pump in the container. The locking fingers are mounted to the closure and normally spaced in unlocking relation from the pump piston but are yieldably flexible for bending toward the piston. The lock actuating member has cam elements which upon rotation of the lock actuating member forcibly bend the fingers toward the piston and into a locking relation therewith. Reciprocal movement of the pump actuating member relative to the lock actuating member is used to actuate the piston. Also, rotational movement of the pump actuating member is used to cause rotation of the lock actuating member therewith for bending the fingers from their unlocking to locking relations.

  • Patent number: 4757922
    Abstract: A dispenser for liquid acrylic resin and powder, the dispenser having a dish, a raised inlet above the dish, and a shield for the inlet. A bottle or the like is mounted in coaxial relation therewith for dispensing fresh quantities of liquid from the reservoir bottle to the dispenser dish. The outlet in the dispenser dish is above the level of the liquid contained in the dish to prevent return of the liquid and has an umbrella-like shield over the inlet to prevent the backflow to prevent contaminated resin from returning to the bottle.
