发明名称 PLASTIC ENVELOPE ASSEMBLY AIR FRESHENER DISPENSER DEVICE
摘要 This invention provides an air freshener dispenser device that is in the form of a plastic envelope which has a content of a volatile air freshener medium. In one embodiment the envelope is constructed of two elongated plastic membrane laminates which are sealed along a peripheral margin that frames a reservoir enclosure between the opposing membrane laminate inner surfaces. Each membrane laminate is composed of an inner vapor-permeable thin film, and an outer vapor-impermeable thin film. The reservoir enclosure additionally contains an unattached semi-ridig strip which has dimensions that closely approximate the area dimensions of the reservoir enclosure, and which has at least one structural aperture which permits free access between the membrane laminate range surfaces. The strip provides semi-rigidity to the air freshener dispenser device.
