Abstract: A dispensing device dispenses volatile material into the atmosphere. The dispensing device has a reservoir for holding the volatile material, and a wick in contact with the volatile material and the atmosphere. A wick retainer is positioned in an opening of the reservoir. The wick retainer has one or more pivoting engagement members mounted in a retainer body. The engagement members pivot into engagement with the wick and retain it within the reservoir.

Abstract: A molded retainer and a method for making the molded retainer are provided. The molded retainer includes a body defining a coupling sleeve, molded from a plastic material and defined by one or more sidewalls. An axial opening is formed in the sleeve about a central axis and at least one transverse engagement opening is formed in the sidewall. An engagement member is integrally molded with the retainer body and is pivotably attached to the sidewall within the engagement opening. The engagement member is pivotable between a first position and a second position, wherein in the first position at least a portion of the engagement member is positioned within the axial opening for engagement with a structure positioned within the axial opening.

Abstract: A device for passively diffusing a liquid to the air of a surrounding area. A reservoir holds the liquid, the reservoir having a top end with an aperture therethrough. A non-planar wick extends 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. The wick is formed of a fibrous, porous sheet of material having a top edge and a bottom edge of substantially the same width. The sheet of material is gradually gathered along a length of the sheet of material such that the upper end of the wick is less gathered than the lower end of the wick and the wick is self-supported in an upright position within the aperture.
