The carbonation device includes a cap system selectively mounted to the mouth of a liquid container. The cap system includes a cap, a syringe piston reciprocable within the cap, an actuating mechanism for reciprocating the syringe piston, and a reaction vessel selectively attached to the bottom of the cap. The syringe piston includes a storage area to be filled with water by repeated activation of the actuating mechanism. The water from the charged syringe piston discharges into the reaction vessel that has been filled with a preselected amount of reactants to initiate the carbonation reaction. In an alternative embodiment, the carbonation device includes a rotatable control ring to selectively puncture a CO2 cartridge inside the reaction vessel or introduce water into the reaction vessel to initiate carbonation reaction. In both embodiments, the CO2 flows from the reaction vessel into the container to carbonate the beverage contained therein.

1. A carbonation device, comprising: a substantially hollow cap adapted to be mounted to an opening of a liquid container;a reciprocating syringe piston slidably mounted on the cap, the syringe piston having a bowl for holding and dispensing water and gas;an actuating mechanism mounted on the cap for selectively reciprocating the syringe piston;a reaction vessel mounted on the cap, the reaction vessel being adapted to hold carbonating gas producing reagents to be mixed with the water, anda carbonating gas distribution system connected to the cap, the system dispensing the carbonating gas into liquid held in the liquid container;wherein operation of the actuating mechanism creates a vacuum for drawing the water into the bowl, the water being dispensed into the reaction vessel to be mixed with the reagents and thereby produce carbonating gas for carbonating beverage inside the liquid container. 2. The carbonation device according to claim 1, wherein the cap includes a handle loop. 3. The carbonation device according claim 1, wherein said cap comprises first internal threads for mounting the cap onto the liquid container, the first internal threads having a diameter, and second internal threads concentric with the first internal threads, the second internal threads mounting said reaction vessel, the second internal threads having a diameter smaller than the first inner threads. 4. The carbonation device according to claim 1, wherein the syringe piston comprises: an upwardly extending piston rod centrally disposed in said bowl, the piston rod having a pivot pin pivotally connected to said actuating mechanism; anda vent post formed at the bottom of said bowl, the vent post having a throughbore permitting flow of water or gas into and out of said bowl. 5. The carbonation device according to claim 4, wherein the syringe piston further comprises a plurality of reinforcing ribs in said bowl for maintaining shape of said bowl. 6. The carbonation device according to claim 5, wherein the syringe piston further comprises a plurality of handle fins integral to said bowl. 7. The carbonation device according to claim 1, wherein said cap has a recess defined therein, said actuating mechanism comprising: a cam lever mounted in the recess in said cap, the cam lever having a portion thereof pivotally attached to said syringe piston;at least one follower disposed on one end of the cam lever; anda cam channel formed in the recess in said cap;wherein raising and lowering of the cam lever reciprocates said syringe piston. 8. The carbonation device according to claim 7, further comprising a locking mechanism for locking the cam lever in a lowered position. 9. The carbonation device according to claim 8, wherein the locking mechanism comprises: an elongate locking bar extending perpendicular to said cam lever, said locking bar having a cross-sectional shape and a discontinuous section;a pair of spaced mounting slots formed in said recess, said slots having a shape corresponding to the cross-sectional shape of said locking bar; anda central rib on said cam lever, the central rib having a slot, the slot having a shape corresponding to the cross-sectional shape of said locking bar;wherein said locking bar is slidable in said mounting slots to a locked position where the cross-sectional shape of the bar mates with the shape of the slot in said central rib, forming a locking joint, and to an unlocked position where said discontinuous portion mates with the slot in said central rib. 10. The carbonation device according to claim 1, further comprising a pressure relief valve disposed on top of said cap. 11. The carbonation device according to claim 10, wherein said pressure relief valve comprises: a ball received in a recess on said cap, the ball covering a vent hole;an elongated spring biasing the ball against the vent hole at one end; anda nut disposed against the other end of the spring. 12. The carbonation device according to claim 11, further comprising a plurality of seals pressure-sealing said cap, said reaction vessel and said syringe piston.
