Embodiment Construction

[0070] figure 1 An aerosol-generating article 10 according to one embodiment of the invention is shown. The aerosol-generating article 10 is a filter cigarette comprising an aerosol-generating substrate 12 and a mouthpiece 14 in the form of a wrapped tobacco rod. The mouthpiece 14 is secured to the wrapped tobacco rod by a tipping wrap 16 .

[0071] Such as figure 2 shown more clearly in , which shows figure 1 A longitudinal cross-sectional view of the aerosol-generating article 10 of the mouthpiece 14 including an upstream filter section 18 at the upstream end of the mouthpiece 14 and a downstream filter section 20 at the downstream end of the mouthpiece 14 . The mouthpiece 14 also includes a substantially transparent liquid delivery element 22 positioned between the upstream filter segment 18 and the downstream filter segment 20 . A substantially transparent combined filter segment wrapper 24 is wrapped around the upstream and downstream filter segments 18 , 20 and the ...

Abstract

An aerosol-generating article (10) is provided comprising an aerosol-generating substrate (12) and a mouthpiece (14) secured to a downstream end of the aerosol-generating substrate (12). The mouthpiece (14) includes at least a length of filter material (18) and a liquid delivery element (22). The liquid delivery element (22) includes an upstream end and a downstream end, a cavity (28) containing a liquid, and at least one channel (26). The liquid delivery element (22) is arranged to deliver the liquid to the at least one length of filter material (18) when activated by a consumer.

Description

technical field [0001] The present invention relates to an aerosol-generating article comprising a liquid delivery element. The invention is particularly applicable to elongated smoking articles such as cigarettes. Background technique [0002] Smoking articles, such as cigarettes, typically include an aerosol-generating article, such as a tobacco rod, attached to a mouthpiece. Conventional mouthpieces include one or more sections of filter material, such as cellulose acetate tow. In some cases it may be desirable to provide liquid within the filter material to alter the taste experienced by the consumer during smoking the smoking article. For example, it may be desirable to provide water or liquid fragrance within the filter material. However, liquid deposited directly on the filter material during manufacture of the smoking article may escape during storage and cause staining of other parts of the smoking article or of the packaging. Volatile liquids deposited directly...
