Benefits of technology

The present patent describes a smoking article that uses hollow elements, such as filters and tubes, to improve the user experience. By filtering and mixing the vapor, the article provides a resistance to draw that is similar to conventional tobacco products, while minimizing the risk of particles or unmixed vapor components reaching the user's mouth. The filter membrane is positioned in the flow path of the vapor to improve particle size by slowing down the cooling rate of the vapor. The filter membrane acts as a second heating element, reducing the temperature difference experienced by the vapor as it moves from the smoking body to the user mouth via a mouthpiece. The hollow element is attached to the smoking body in an end-to-end relationship, elongating the smoking body. The elongated smoking article also includes a tipping paper that circumscribes the smoking body and the hollow element and connects them. The technical effects of the invention include improved particle size, reduced risk of particles or unmixed vapor components reaching the user's mouth, and improved vapor production.

Problems solved by technology

However, due to the hollow bore extending through the whole filter element, the filtering capacity is limited.

first embodiment

[0093]FIG. 2 illustrates a schematic perspective view of an elongated smoking article 100 according to the present disclosure. The elongated smoking article 100 of FIG. 2 differs of that from FIG. 1 in that a disc-shaped filter membrane 50 is positioned in between the smoking body 10 and the hollow bore filter element. The filter membrane is adhered to the first base area 21 of the hollow bore filter element 20 and / or wedged between the smoking body 10 and the hollow bore filter element 20 by indirect force closure due to the wrapping paper (not shown). The filter membrane 50 comprises a plurality of aperture openings 55 that are aligned with the hollow bore 25 of the hollow bore filter element 20 as schematically shown in FIG. 2. The function of the filter membrane 50 is described in detail with respect to FIG. 5 and a redundant description is thus omitted with respect to FIG. 2.

second embodiment

[0094]FIG. 3 illustrates a schematic perspective view of an elongated smoking article 100 according to the present disclosure. The elongated smoking article 100 of FIG. 2 differs of that from FIGS. 1 and 2 in that a first portion 51 of the filter membrane 50 is attached to a lateral surface of the hollow bore filter element 20. A second portion 52 of the filter membrane 50 is bent from the first portion 51 and over the first base area 21 of the hollow bore filter element 20. A plurality of aperture openings (not shown) are arranged in the second portion 52 and aligned, i.e., overlaid, with hollow bore 25. The filter membrane 50 is advantageously well attachable to the hollow bore filter element 20.

[0095]FIG. 4 illustrates a schematic perspective view of a hollow bore filter element 20 according to an embodiment and schematic front views of the base areas 21, 22, of such hollow bore filter element 20. The hollow bore filter element 20 has a first portion 51 of a filter membrane 50 at...

fourth embodiment

[0101]FIG. 9 illustrates a side view of an elongated smoking article 100 according to a Again, the elongated smoking article 100 comprises a smoking body 10 at the upstream end of the elongated smoking article 100. The smoking body 10 comprises reconstituted tobacco as combustible material 11 which includes nicotine as a volatile compound. The combustible material 11 comprises 65 wt % tobacco which is provided in the form of gathered shreds produced from a sheet of slurry / paper recon tobacco. The tobacco is dosed with 20 wt % of a humectant such as propylene glycol (PG) or vegetable glycerine (VG) and has a moisture content of between 7 to 9 wt %. The combustible material 11 further comprises cellulose pulp filler and guar gum binder. The smoking body 10 is formed in a substantially cylindrical shape such that the elongated smoking article 100 resembles a conventional cigarette. It has diameter of around 7 mm and an axial length of around 12 mm.

Abstract

An elongated smoking article is described that comprises a cylindrical smoking body with a combustible material and a hollow bore filter element downstream to the cylindrical smoking body. The hollow bore filter element comprises a first base area facing the smoking body and a second base area opposite the first base area and a hollow bore extending from the first base area to the second base area. The elongated smoking article further comprises a filter membrane that is arranged between the smoking body and the hollow bore filter, that comprises at least one filter aperture aligned with the hollow bore, that is configured for filtering particles emitted by the heated smoking body, that is permeable for vapor emitted by the heated smoking body and has an effective size between 0.5 μm and 1.5 mm.

Description

INCORPORATION BY REFERENCE[0001]The present disclosure is a continuation of, and claims priority to, international patent application no. PCT / EP2019 / 079366 filed on Oct. 28, 2019, claiming priority to applications nos. GB1817558.8, filed Oct. 29, 2018, and EP19187689.5, filed on Jul. 23, 2019.FIELD OF THE DISCLOSURE[0002]The present disclosure relates to an elongated smoking article comprising a smoking body filled with a combustible material and a hollow element downstream to the cylindrical smoking body and comprising a first base area facing the smoking body. A filter membrane is disposed between the smoking body and the hollow element and comprises at least one filter aperture that is aligned with the hollow bore of the hollow element, that is permeable for vapor emitted by the heated smoking body and that has an effective size between 0.5 μm and 1.5 mm. The present disclosure further refers to a smoking system comprising the elongated smoking article of the disclosure and a hea...
