Passive Diffuser Having a Non-Planar Wick

A device for passively diffusing a liquid to the air of a surrounding area, the device comprising:

• a reservoir that holds the liquid, the reservoir having a top end with an aperture therethrough;
• a non-planar wick extending through the aperture such that a lower end of the wick remains in contact with the liquid in the reservoir and an upper end of the wick is exposed to the surrounding area;
• and
• a collar coupled to the reservoir and surrounding the wick within the aperture;
• wherein the collar provides a liquid-tight connection between the wick and the reservoir.

• a collar coupled to the reservoir and surrounding the wick within the aperture, so as to provide a liquid-tight connection between the wick and the reservoir;
• and
• a screen surrounding the reservoir and the wick, the screen having a base supporting the reservoir and sidewalls extending upwardly from the base and shielding the wick;
• wherein the wick is pleated along a plurality of longitudinally extending bend lines, two adjacent bend lines defining a longitudinally extending wall segment of the wick;
• and
• wherein the lower end of the wick is gathered such that adjacent wall segments face one another in substantially parallel relationship, and the upper end of the wick is splayed out such that adjacent wall segments extend at an angle to one another.
