Abstract
This wicking apparatus includes a liquid reservoir, a wick holder, and a wick.The wick holder has a top part for fitting on the reservoir neck and a bottom part for insertion into the reservoir opening, the top part being plate-formed with a central opening, and with two peripheral projections that are spaced apart and that extend downward from the plate towards the reservoir body, projections for contacting inner and outer walls of the reservoir neck, and a second projection for contacting an outer wall of the reservoir neck, the bottom part having wick supporting arms that extend downwards and have flexible end portions projecting inwardly towards the centre of the reservoir opening. The wick is step-shaped with a larger diameter part, and a smaller diameter part: the interface between them defines a shoulder which is supported and held in place by the flexible end portions of the supporting arms.
