Air freshener dispenser device with dual cartridge capacity

摘要

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.
