Abstract
Abstract A dispenser is provided for vaporizable materials such as deodorants and insecticides. The dispenser is adapted to create accentuated air flow over the materials either in the presence of ambient air flow or when the dispenser is moved through the air, for example, by being mounted on the back of a door. It dispenses far smaller quantities in the absence of air movement. The dispenser includes one or more material containers open at one end and mounted within a vented housing. The vents on the housing are positioned over a portion of the open end of the contained material, and are recessed in a concave area of the housing. The housing is spaced from the material container and has exit ports along its periphery. The containers preferably have a dividing partition passing part way down the material container to provide paths for the air to flow down one side and up on the other for better contact with the vaporizable material. The result is that relative motion between the dispenser and the ambient air creates one-way air flow pattern into the central ports, across the vaporizable material, and out the back of the unit. The unit is mounted in a place where it will periodically be moved, such as on a door, or where it would be subject to periodic air flows, such as on the wall adjacent a door.
