Abstract:
1. A convection-driven vaporizing dispenser comprising a first container having a vertically ascending air passageway from at least one first lower air-inlet port to at least one higher air-outlet port; residing in said first container and contactable by air in said passageway at least one volatile compound to be dispensed, said at least one volatile compound being a solid or being a liquid held in a solid; residing in said first container in thermal contact with air in said air passageway a chemical reaction heater having a useful operating life of at least several minutes; and physical separation means, compromisable by a user, associated with said dispenser for preventing activation of the chemical reaction heater by isolating reactants from each other, wherein when a user compromises the physical separation means, the heater activates and wherein during use the chemical reaction heater induces convective airflow through said passageway such that air enters through said at least one bottom air-inlet port, is heated and passed over the at least one volatile compound, and wherein heated air carrying vaporized volatile compound is dispensed through said at least one outlet port.
