ABSTRACT:
By securely sealing odor absorbing material and fragrance producing compositions separately in a flexible container, preferably formed from multi-layered sheet material, a unique and highly desirable air freshening and deodorizing system is attained. In the preferred embodiment, the odor absorbing material is retained by at least one microporous or permeable membrane to prevent unwanted dispersion of the odor absorbing material into the ambient surroundings, while also controlling the rate of transfer of the ambient air into contact with the odor absorbing material. In addition, fragrance producing compositions are incorporated into the container to provide the desired fragrance simultaneously with the absorption of odors from the ambient surroundings. Preferably, the air freshening and deodorizing system of this invention employs a small, compact and flexibly moldable container or housing which enables the system to be easily positioned in any desired location, regardless of the size constraints imposed thereon.
