发明名称 FILTERED CIGARETTE COMPRISING A TUBULAR ELEMENT IN FILTER
摘要 <p>The invention provides a cigarette with a filter element comprising at least one longitudinally extending section of filter material. The section of filter material comprises a smoke-altering material therein that is useful for removing a quantity of vapor phase chemicals from the mainstream smoke. The section of filter material further comprises one or more tubes inserted into and extending through section of filter material. The one or more tubes each define a channel adapted for passage of mainstream smoke through the section of filter material while substantially avoiding contact of the portion of mainstream smoke therein with the smoke-altering material. The provision of a portion of mainstream smoke substantially unaltered by the smoke-altering material can be useful to retain certain desirable taste and other sensory properties of the mainstream smoke.</p>
