First Claim
1. A device (1) for holding and dispensing liquids that provides precise dosages of the liquid, comprisinga bottle (2) for holding the liquid, said bottle extending between a bottle bottom (3) and a bottleneck (4),a cap (5) which is irremovable from the bottleneck, said cap being associated with a hollow cylinder (6) extending axially to near the bottle bottom (3) and having a open upper end and a closed lower end with a central opening (7),a reciprocating dispenser fitting within the cylinder (6) comprising a barrel (8) and a plunger (9), wherein the barrel (8) includes an upper portion (10) having a larger diameter than the lower portion (11) for assuring an air- and liquid-tight fit between the upper portion and the interior wall of the cylinder (6), and having a closed lower end with a central opening (12) that is aligned with the central opening (7) in the cylinder (6), and wherein the plunger (9) includes a piston (13) forming an air- and liquid-tight fit with the interior wall of the barrel (8), a graduated piston rod (14) and a knob (15).

Abstract
A childproof device (1) for holding and dispensing liquids, in particular medicines, that provides precise dosages of liquid, comprising a bottle (2), a cap (5) which is irremovable from the bottleneck (4), said cap being associated with a hollow cylinder (6) extending axially to near the bottle bottom (3) and a reciprocating dispenser comprising a barrel (8) and a plunger (9). The dispenser provides the only means of getting medicine out of the bottle since the cylinder associated with the cap prevents the contents of the bottle from being poured or shaken out. The device is easily assembled and can be stored, sold and used as supplied by the manufacturer.
