Abstract: 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.

Abstract: This invention provides an air freshener dispenser device which consists of twin cartridges which are connected end-to-end with a flexible hinge means. The two cartridges can be folded together and incorporated in a dispensing holder as multiple refill units. Each cartridge is composed of a shallow tray which contains a volatile air freshener medium, and which has its open surface sealed with a coextensive bonded laminate of an inner vapor-permeable membrane and an outer peelable vapor-impermeable membrane. Removal of the peelable vapor-impermeable membrane sealing the two trays allows delivery of the air freshener medium as vapor into the environment at a controlled rate over an extended period of time.
