发明名称 Air freshener dispenser device
摘要 This invention provides an air freshener dispenser device in the form of a semi-rigid thermoplastic strip, which has the central area of both flat surfaces covered with a coextensive laminate of an inner vapor-permeable membrane and an outer peelable vapor-impermeable membrane. The respective membrane laminates enclose the central area of the strip which has at least one aperture accessing between the two laminate films. Preferably there are multiple apertures which serves as a reservoir for a volatile air freshener ingredient. Partial or complete removal of one or both peelablevapor-impermeable membranes allows delivery of the air freshener ingredient as vapor into the environment at a controlled rate over an extended time period.
