Abstract
Abstract A device for controlling the release of vapors such as insect attractants, insecticides, and other vapors such as flower fragrances (the release being a timed matter in accordance with a predetermined configuration of the device), consisting of a microdispenser for accurately controlled dissemination of vaporizable materials comprising an elongated conduit of regulated cross-sectional area and length, and a vaporizable substance enclosed in said conduit. The filamentary conduit has one open and one closed end. In another variant, a filamentary conduit can be sealed between two open ends to provide a pair of end-to-end closed end conduits. The vapor producing substance is placed in the capillary conduit by suitable means. A single filamentary tube may be used, or a plurality of such tubes together. Liquid is contained within the conduit against the action of gravity and vibrations.
