Spill-proof, passive air freshener refill cartridge

A spill-proof, passive air freshener refill cartridge comprising:

• a fragrance supply canister having a lower reservoir that is capped with a top cover which incorporates a downwardly-projecting central well, the bottom of which is below a level of liquid fragrance contained within the canister, and sealed closed with a puncturable membrane;
• a wick having both a pole component which can be pushed in a downwardly direction within the well so as to puncture the membrane and immerse a lower portion of the pole component within the liquid fragrance in order to activate the refill cartridge, and a component exposed to the atmosphere, said exposed component being in contact with the pole component so that liquid fragrance from the pole component is transferred via capillary action to the exposed component from which said liquid fragrance can evaporate into the atmosphere at a controlled rate;
• and
• a wick container that surrounds the exposed wick component, said wick container having a wick cage structure that is unitary with a base having a central aperture through which the wick pole component projects into the well.

A spill-proof, passive air freshener refill cartridge comprising:

• a fragrance supply canister having top cover with a downward projecting well, the bottom of which is below the level of liquid fragrance contained within the canister, and sealed closed with a puncturable membrane;
• a tripartite wick having a cylindrical wall component, a lower surface of which is in contact with a laminar disc component, which, in turn, is unitary with a downwardly projecting pole component that is equipped with at least one sharpened feature, said tripartite wick being downwardly movable so that the sharpened feature of the pole punctures the membrane and a lower portion of the pole component becomes immersed in the liquid fragrance in order to activate the refill cartridge, thereby enabling liquid fragrance to climb the pole component via capillary action and enter both the laminar disk component and the cylindrical wall component which are both at least partially exposed to the atmosphere, and from which liquid fragrance can evaporate at a controlled rate;
• and
• a wick holder that surrounds the exposed wick components, said wick container having a wick cage structure that is unitary with a base having a central aperture through which the wick pole component projects into the well.
