Aerosol-generating article and method for manufacturing aerosol-generating articles

Abstract

The aerosol-generating article (1) comprises a tobacco element and a mouthpiece element. The tobacco element comprises an aerosol-forming substrate (2), a support element (3) arranged downstream of the aerosol-forming substrate (2) and an aerosol-cooling element (4) arranged downstream of the support element. The mouthpiece element comprises a filter segment (5) and a hollow tube (6). The aerosol-cooling element (4) has a length of at most 15 millimeter. A length of the mouthpiece element is adapted according to the length of the aerosol-cooling element (4) such that a total length of the aerosol-generating article (1) is kept at a predefined total length. The invention also relates to a method for manufacturing aerosol-generating articles.

Description

technical field

[0001] The present invention relates to aerosol-generating articles and methods for making aerosol-generating articles. In particular, the present invention relates to aerosol-generating articles for use in electrical heating devices. Background technique

[0002] Various aerosol-generating articles for use in electric heating devices are known. They comprise a plurality of segments including an aerosol-forming substrate and a mouthpiece. Other sections may be aerosol treatment sections, eg, for modifying aerosol characteristics.

[0003] Aerosol-generating articles are produced on a large scale. The smallest reduction in overhead to manufacture a single article can have a huge impact on overall production costs.

[0004] Accordingly, there is a need to have a reduced cost aerosol-generating article and a method for manufacturing such a reduced cost aerosol-generating article. In particular, there is a need to have a reduced cost aerosol-generating artic...

Examples

Embodiment Construction

[0065] figure 1 (as well as Figure 4c , see below) illustrates an aerosol-generating article 1 comprising the following five elements: an aerosol-forming substrate 2, a support element in the form of a hollow cellulose acetate tube 3, an aerosol cooling element 4, a mouthpiece filter 5 and a cardboard tube 6 . These five elements are arranged sequentially and coaxially aligned, passing through the cigarette paper 7 and passing through the tipping paper 8 ( Figure 4c shown in ) are assembled to form strips. The strip has an oral end 22 which a user inserts into his or her mouth during use, and a distal end 23 at the opposite end of the strip opposite the oral end 22 . Elements located between the oral end 22 and the distal end 23 may be described as upstream of the oral end 22 , or alternatively as downstream of the distal end 23 . The cardboard tube 6 is located at the mouth end 22 of the aerosol-generating article 1 and the aerosol-forming substrate 2 is located at the ...
