Definitions
- US 2015/0296875 A1 discloses a smoking article comprising: a mouthpiece comprising one or more segments and a substantially transparent wrapper circumscribing at least a portion of the one or more segment, wherein the substantially transparent wrapper comprises at least one of cellulose diacetate film and biaxially oriented polypropylene film; a paper wrapper circumscribing at least a portion of the mouthpiece and a portion of the aerosol generating substrate; and a window in the paper wrapper so that an underlying mouthpiece segment can be viewed through the window and the substantially transparent wrapper.
- the filter cigarette 10 shown in Figures 1 and 2 comprises a wrapped rod 12 of tobacco cut filler which is attached at one end to an axially aligned filter 14 comprising a single filter segment 16.
- the single filter segment 16 is formed of cellulose acetate tow which has been wrapped with a substantially transparent wrapper in the form of substantially transparent plug wrap 18.
- the filter segment 16 incorporates particles of a cellulosic material (not shown) impregnated with a liquid flavourant, which are dispersed within the cellulose acetate tow.
- the wrapped tobacco rod 12 and the filter 14 are joined by an outer wrapper 20 formed of standard tipping paper, which circumscribes the entire length of the filter 14 and an adjacent portion of the tobacco rod 12.
- the outer wrapper 20 is secured to the substantially transparent plug wrap 18 at adhesive bond points (not shown) spaced around the circumference of the filter 14.
