发明名称 Chemical dispensing device and method
摘要 The present invention is a device and method for selectively dispensing at least one target compound into a selected environment. A target compound is dissolved within an elastomer compound in a concentration that supersaturates the elastomer compound. The elastomer compound is then shaped into a selected form that is conducive to placement within the selected environment. The target compound within the elastomer compound begins to bloom to the surface of the elastomer compound where it is exposed to the surrounding environment. The bloom of the target compound into the surrounding environment continues until the concentration of the target compound within the elastomer compound reaches its saturation point. As such, the duration of the bloom of the target compound from the elastomer compound can be regulated by the concentration of the target compound within the elastomer compound, the volume of the elastomer compound and the surface area of the elastomer compound.
