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.
Dispositif de distribution de désodorisant d'ambiance constitué d'une enveloppe plastique contenant une substance désodorisante volatile. Selon un mode de réalisation, l'enveloppe est constituée de deux couches de membrane plastique allongée fixées le long d'une marge périphérique encadrant une enceinte formant réservoir entre les surfaces intérieures des membranes opposées. Chaque membrane est composée d'une pellicule intérieure fine perméable à la vapeur et d'une pellicule extérieure mince imperméable à la vapeur. L'enceinte formant réservoir contient en outre une bande semi-rigide non fixée dont les dimensions sont très proches des dimensions de la surface du réservoir, et qui comporte au moins une ouverture structurale permettant le passage entre les surfaces des membranes. La bande assure la semi-rigidité du dispositif distributeur de désodorisant d'ambiance.
