The present invention relates to the use of porous materials, for transporting liquids from a reservoir (104) in a vapor dispensing device (100) which addresses many of the shortcomings of the prior art, by selecting pore sizes and void volume ratios of the various wicking materials to fall within an effective range to obtain effective control of liquid delivery. For example, in accordance various aspects of the present invention, a porous polymeric wick (102) is comprised of various polymeric materials having pore sizes less than about 250 microns and void volume ratios from about 25 to about 60 %.
L'invention concerne l'utilisation de matériaux poreux, pour transporter des liquides d'un réservoir (104) vers un dispositif de distribution de vapeur (100) qui palie beaucoup d'inconvénients de l'art antérieur, par sélection de dimensions de pore et d'indices de volume de vide de divers matériaux mèches afin de les amener dans les plages de mesure permettant d'obtenir un contrôle efficace de la distribution de liquide. Selon divers aspects de l'invention, une mèche polymère poreuse (102) est, par exemple, constituée de plusieurs matériaux polymères possédant des dimensions de pore inférieures à environ 250 microns et des indices de volume de vide compris entre environ 25 et 60 %.
