Claim 7:
8. A fluid delivery kit for refilling electronic cigarette cartridges, comprising:
a pipette head key and a lock mechanism, wherein the pipette head key is disposed to one end of a refill bottle, the pipette head key being configured to rotatably engage with the lock mechanism located on a mounting base, the mounting base retaining the lock mechanism, the lock mechanism being freely rotatable internal to the mounting base;
wherein the rotatable engagement of the lock mechanism by the pipette head key is configured to result in an open position of a liquid filling hole, said open position permitting fluid delivery into a liquid tank, the liquid filling hole further configurable to a closed position, said closed position preventing fluid escape from the liquid tank;
wherein the lock mechanism is further configured to have a second liquid inflow hole and an entrapment notch;
wherein the pipette head key is configured to have a protruding shape, the liquid filling hole is configured to have an intruding shape, wherein the shapes are configured to match such that protruding shape of the pipette head key is insertable in the intruding shape of the liquid filling hole;
wherein the pipette head key further has an entrapment protrusion, the entrapment protrusion configured to engage with the entrapment notch;
wherein the rotational engagement of the pipette head key with the lock mechanism results in the alignment of the first liquid inflow hole with a second liquid infill hole resulting in a liquid inflow passageway which is unobstructed
wherein the rotational engagement of the pipette head key with the lock mechanism results in the misalignment of the first liquid inflow hole with the second liquid infill hole resulting the liquid inflow passageway being obstructed; and,
wherein the rotational engagement of the pipette head key with the lock mechanism results the entrapment protrusion being entrapped between an entrapment ledge and the entrapment notch simultaneous with the alignment of the first liquid inflow hole with the second liquid infill hole prohibiting removal of the pipette head key from the lock mechanism.
