First Claim
1. A medication dispensing apparatus comprising:
- a liquid container having an open end;
a cap assembly engagably removable from the open end of said container comprising;
an external cap having a lower end;
an inner fixing means adapted to be fitted into the open end of said liquid container and connected to the lower end of said external cap;
a dropper means, for dispensing liquid, connected through said inner fixing means and having a fluid passageway;
activation means for aspirating liquid from the container into the dropper means comprising;

Abstract
A medication dispensing apparatus comprising a liquid container having an open end and a cap assembly engagably removable from the open end of the container. The cap assembly comprises an external cap having a lower end, an inner fixing element adapted to be fitted into the open end of the liquid container and connected to the lower end of the external cap. The cap assembly further comprises a dropper connected through the inner fixing element and having a fluid passageway and activation element for aspirating liquid from the container into the dropper. The activation element comprises a piston mounted in sliding relationship within the fluid passageway of the dropper and having a first position at the lower end of the fluid passageway and a second position at the upper end of the fluid passageway, and an actuating elemnt disposed within the external cap and connected to the piston for advancing or retracting the piston within the fluid passageway thereby aspirating liquid from the container when the piston is retracted from its first position to its second position.

8. A medication dispensing apparatus comprising:
-
a liquid container having an open end; a cap assembly engagably removable from the open end of said container comprising; an external cap having a lower end; an inner fixing means adapted to be fitted into the open end of said liquid container and connected to the lower end of said external cap; a dropper means, for dispensing liquid, connected through said inner fixing means and having a fluid passageway; activation means for aspirating liquid from the container into the dropper means comprising; a piston mounted in sliding relationship within said fluid passageway of said dropper means and having a first position at the lower end of said fluid passageway and a second position at the upper end of said fluid passageway; and actuating means disposed within said external cap and connected to said piston means for advancing and retracting said piston within said fluid passageway thereby aspirating liquid from said container when said piston is retracted from its first position to its second position, wherein said actuating means comprises; a rod member; and activating means for moving the rod member; said rod member having upper and lower portions, said lower portion longitudinally extending within said fluid passageway and fixedly connected at its lower end to said piston, said upper portion connected to said activating means, wherein said activating means comprises an electrically actuated solenoid;
wherein said upper portion of said rod member comprises a track engagable with said solenoid and movable as a function of the position of said solenoid.

9. A medication dispensing apparatus comprising:
-
a liquid container having an open end; a cap assembly engagably removable from the open end of said container comprising; an external cap having a lower end; an inner fixing means adapted to be fitted into the open end of said liquid container and connected to the lower end of said external cap; a dropper means, for dispensing liquid, connected through said inner fixing means and having a fluid passageway; activation means for aspirating liquid from the container into the dropper means comprising; a piston mounted in sliding relationship within said fluid passageway of said dropper means and having a first position at the lower end of said fluid passageway and a second position at the upper end of said fluid passageway; and actuating means disposed within said external cap and connected to said piston means for advancing and retracting said piston within said fluid passageway thereby aspirating liquid from said container when said piston is retracted from its first position to its second position, wherein said actuating means further comprises dosage control means for setting the amount of liquid aspirated into the dropper means, said dosage means comprising limit means disposed within said cap assembly for preventing the upper portion of said rod member from traveling past a predetermined point;
wherein said limit means comprises an elongated pin extending from a side wall of said external cap and engaging a portion of the upper portion of said rod member during its travel, thereby preventing further travel thereof.
