Multi-shape lock and key system for an electronic cigarette cartridge and refill bottle therein

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.

An electronic cigarette refill system, comprising:

• a mounting base, a lock mechanism, an atomization chamber, and a casing;
• wherein the mounting base has an opening, the lock mechanism being placed internal to the opening and the atomization chamber and mounting based positioned on either end of the lock mechanism enclosing the lock mechanism, the lock mechanism maintaining free rotational movement while in an enclosed configuration;
• the mounting base, the atomization chamber, and the lock mechanism being placed internal to the casing, wherein the casing forms a first portion of a liquid tank and the atomization chamber forms a second portion of the liquid tank, thereby defining the entire tank;
• the mounting base having a first liquid inflow hole, the lock mechanism having a ceiling and a second liquid inflow hole positioned nearer the liquid tank, the lock mechanism further having and a liquid filling hole configured to insertably accept a pipette head key, upon insertion of the pipette head key into the lock mechanism, the lock mechanism and the pipette head key being rotatable about one axis, the ceiling of the lock mechanism rotating and resulting in the alignment of the first liquid inflow hole and the second liquid inflow hole to form a liquid inflow passage;
• said alignment corresponding to a transition from a closed configuration to an open configuration, the liquid inflow passage corresponding to free liquid movement from a refill bottle to the internal portion of the liquid tank;
• and,
• wherein the rotational engagement of the pipette head key with the lock mechanism results an entrapment protrusion being entrapped between an entrapment ledge and an entrapment notch simultaneous with the alignment of the first liquid inflow hole with a second liquid infill hole prohibiting removal of the pipette head key from the lock mechanism.
