Abstract: front page image
(EN)A filter element incorporating an adsorbent material is provided. The filter element may comprise a first section of filter material and a second section of filter material spaced apart to form a compartment therebetween. The compartment may be filled with one or more adsorbents or the compartment may be divided into two regions, wherein one compartment region is filled with an adsorbent and the other compartment region is either filled with an ion-exchange resin or remains empty. The section of filter material adjacent to the tobacco rod may include one or more channels therethrough for, passaging smoke directly from the tobacco rod into the adsorbent-filled compartment. The mouth end section of filter material may contain a breakable capsule, wherein the breakable capsule is filled with a flavoring agent capable of altering the taste characteristics of mainstream smoke.
(FR)L'invention concerne un élément filtrant intégrant un matériau adsorbant. Ledit élément filtrant peut comprendre une première section de matériau filtrant et une seconde section de matériau filtrant à distance l'un de l'autre et formant entre elles un compartiment. Ce compartiment peut être rempli d'au moins un adsorbant ou divisé en deux zones, l'une remplie d'un adsorbant, l'autre remplie d'une résine d'échange d'ions ou restant vide. La section du matériau filtrant jouxtant la barre de tabac peut comporter au moins un canal traversant destiné au passage de la fumée directement du tabac au compartiment rempli d'adsorbant. La section extrémité bouche du matériau filtrant peut contenir une capsule cassable remplie d'un agent aromatisant susceptible de modifier les caractéristiques gustatives du flux principal de fumée.
