ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to room deodorizers and more particularly to a room deodorizer that is positional in airflow from a room air circulator such as a fan or a vent.
There are known room deodorizers but none with the convenience and effectiveness made possible by this invention.
Examples of different but related room deodorizers are described in the following patent documents. U.S. Pat. Nos. 5,752,658 and 5,732,882, both by the same principle inventor, Gibbs, issued on May 19, 1998 and Mar. 31, 1998, respectively, described vented circular half shells that contained deodorizer for being hung on a chain of a ceiling fan. Design Pat. No. 334,800, issued to Portis on Apr. 13, 1993, showed a hemispherical container of deodorizer that was strapped to a top of a blade of a ceiling fan. Other fan-blade deodorizers also are known. U.S. Pat. No. 1,687,830, issued to Clevenger on Oct. 16, 1928, described a cylindrical container having holes in a top portion and having a bottom portion which contained liquid deodorizer into which a wick was suspended from a cover on the container for drawing the deodorizer up to be encountered by fan-circulated air passing horizontally through the permeability.
SUMMARY OF THE INVENTION
Objects of patentable novelty and utility taught by this invention are to provide an air-circulator room deodorizer which:
positions an effective deodorizer in airflow from a room air circulator such as a fan or an air-conditioner vent;
is easily replenishable with deodorizer; and
is adaptable to a wide variety of vertical and horizontal room air circulators.
This invention accomplishes these and other objectives with an air-circulator room deodorizer having a permeable container that is sized and shaped to be positioned in airflow from a room air circulator such as a fan or vent and has a deodorant pack that releases deodorant selectively into the airflow.
The above and other objects, features and advantages of the present invention should become even more readily apparent to those skilled in the art upon a reading of the following detailed description in conjunction with the drawings wherein there is shown and described illustrative embodiments of the invention.
