摘要： This invention relates to a device that provides controlled release of a fragrant or deodorizing substance: the fragrant or deodorizing substance being solublized with an appropriate carrier solvent within a polymeric matrix. The layers function as protective barriers, semi-permeable membranes, fragrance reservoirs, and adhesives. The device is capable of delivering a fragrance at a controlled rate for a prolonged period of time through the gradual diffusion and release of fragrant material carried by a solvent from a reservoir system to the semi-permeable UV curable, oligomer composition acting a fragrance release regulator. Additionally, the UV curable, oligomeric composition that forms the reservoir and regulating layer can be engineered to be adhesive through cure inhibition. The method of cure inhibition can also be utilized to create internal areas of high and low cross link density to further control the release rate of a fragrance.
