Embodiment Construction

[0051] figure 1 A sleeve (10) temporarily secured to the mouthpiece of the smoking article is depicted. The sleeve (10) has an open downstream end (40) and an open upstream end (60). The sleeve is hollow and has a lumen extending from an open upstream end (60) to an open downstream end (40) for receiving a mouthpiece of a smoking article. The bushing (10) has a first ventilation zone (50) comprising a plurality of ventilation hole lines (52, 54), in this case three lines. A first line of ventilation holes (52) is provided at a location between 10mm and 15mm from the open downstream end (40) of the sleeve (10).

[0052] figure 1 The sleeve in the invention also includes a second ventilation zone having a perforated line (70) at a position between 10 mm and 15 mm from the open upstream end (60) of the sleeve (10). A sleeve (10) is formed from a tubular body (14) defining an inner surface of the sleeve and an outer covering material (16) defining an outer surface of the sleev...

Abstract

A tube (10) for temporary affixment to a mouthpiece of a smoking article (80), the tube (10) comprising an open upstream end, an open downstream end, an outer surface, and an inner surface defining a lumen for receiving the mouthpiece of the smoking article, the lumen extending from the open upstream end to the open downstream end; the tube further comprising a first ventilation zone (50) for providing ventilation into the lumen of the tube, the first ventilation zone comprising a first line of perforation holes (52) circumscribing the tube at a location at least10mm from the open downstream end of the tube.

Description

technical field [0001] The present invention relates to a sleeve temporarily secured to the mouthpiece of a smoking article, such as a cigarette; and to a smoking article secured with such a sleeve. The invention also relates to a container comprising one or more such sleeves. Background technique [0002] Filter cigarettes typically comprise a tobacco cut filler rod surrounded by a paper wrapper and a cylindrical filter aligned in end-to-end relationship with the wrapped tobacco rod, wherein the filter is attached to the tobacco rod by tipping paper. In conventional filter cigarettes, the filter may consist of a column of cellulose acetate tow wrapped in a porous plunger wrap. Filtered cigarettes are also known having multicomponent filters comprising two or more segments of filter material for removal of particulate and gaseous components in mainstream smoke. [0003] Various smoking articles have also been proposed in the art in which the aerosol-forming substrate, such...
