Patent ID: 7481380

Claim:
A method of releasing at least one volatile material to the atmosphere, the steps of said method comprise (a) providing a non-energized volatile material delivery system, and (b) delivering a continuous maintenance level emission of at least one volatile material, and a temporary boost level emission of at least one volatile material, wherein said boost level emission is delivered by one or more of the following means: inversion, pumping, or spring-action; wherein said delivery system comprises: a) at least one container comprising at least one fluid reservoir; b) at least one evaporative surface device opening located in said at least one container having at least some longitudinal exposure; c) at least one evaporative surface device which is at least partially located in said at least one evaporative surface device opening and in said at least one fluid reservoir; wherein said at least one evaporative surface device is fluidly connected to said volatile material; d) a by-pass tube comprising at least one by-pass tube opening connected to said at least one fluid reservoir for collection of excess volatile material not delivered to said at least one evaporative surface device, wherein said by-pass tube and said at least one evaporative surface device terminate within said at least one evaporative surface device opening, wherein said by-pass tube is in fluid communication with at least some of said excess volatile material not contained in one or more of the following: said fluid reservoir, said unit dose chamber or said at least one evaporative surface device, wherein said delivery system is free of a source of heat, gas, or electrical current, and wherein said at least one volatile material is not mechanically delivered by an aerosol.
