    • A smokable article including an aerosol generating zone which has a combustion element and a carrier for an aerosol precursor which coaxially surrounds the combustion element, flow passages in the aerosol generating zone and a mouthpiece. The combustion element includes axial flow passages extending over its entire length and a jacket formed of a gas-impermeable heat-insulating material. The jacket is surrounded at a distance by a concentric sleeve of a gas-impermeable material so that between the jacket and the sleeve at least one flow space results; the sucked-in air flows through the flow passages in the combustion element, then back through the flow space between the jacket and the sleeve and finally through the carrier for the aerosol precursor to the mouthpiece. The carrier includes a precursor, and the combustion element has a plurality of axial passages.
    • 一种可吸烟制品,包括具有燃烧元件的气溶胶生成区和同时围绕燃烧元件的气溶胶前体的载体,气溶胶生成区中的流动通道和吸口。 燃烧元件包括在其整个长度上延伸的轴向流动通道和由气体不可渗透的绝热材料形成的护套。 护套通过不透气材料的同心套筒一段距离被围绕,从而在护套和套管之间产生至少一个流动空间; 吸入的空气流过燃烧元件中的流动通道,然后流过护套和套管之间的流动空间,最后通过用于气雾剂前体的吸嘴的载体。 载体包括前体,并且燃烧元件具有多个轴向通道。

    • A tip for a smokable article comprises a tubularly arranged covering material with an air-pervious ventilation zone, and also a tubular core which is within the covering material and which contains no filter material. The air-impervious tube wall of this core has a tubular outlet region directed towards the smoker and also a conically tapering inlet region provided with a small inlet aperture and directed towards the tobacco. Between the core and the covering material, through-flow ducts are formed by appropriate shaping of the surface of the core and these in conjunction with the remaining shape of the core define the draw resistance of this tip, and at the same time dilute the smoke through the air aspirated through the ventilation zone.This core can be manufactured from an extruded tubular blank of synthetic plastic material, in which the ducts are formed sectionwise by means of eccentrics.
    • 用于可吸烟制品的尖端包括具有透气通风区的管状布置的覆盖材料,以及在覆盖材料内并且不含过滤材料的管状芯。 该芯的不透气管壁具有指向吸烟者的管状出口区域,还具有设置有小入口孔并指向烟草的圆锥形锥形入口区域。 在核心和覆盖材料之间,通过适当地形成芯的表面形成通流管道,并且这些与芯的剩余形状一起限定了该尖端的牵引阻力,同时稀释烟雾 通过吸气通过通风区。 该芯可以由合成塑料材料的挤出管状坯料制成,其中通过偏心件形成管道。
