The present disclosure is directed to an aerosol delivery device and a holder for use with a removable substrate cartridge. In one implementation, the holder includes a main body defining a proximal end and a distal end, and an outer sleeve configured to slide relative to the main body, the outer sleeve also defining a proximal end and a distal end. The outer sleeve is configured to slide to a use position, in which the proximal end of the main body extends beyond the proximal end of the outer sleeve and the distal end of the outer sleeve extends beyond the distal end of the main body, and a storage position, in which the distal end of the main body extends beyond the distal end of the outer sleeve and the proximal end of the outer sleeve substantially covers the proximal end of the main body.

A smoking article is provided, having opposed lighting and mouth ends, and including a mouth end portion at the mouth end. A tobacco portion is between the lighting end and the mouth end portion. An aerosol-generation system is between the lighting end and the tobacco portion. The aerosol-generation system includes a heat generation portion, comprising an elongate fluted member actuated by ignition of the lighting end. The fluted member defines grooves extending longitudinally between opposed first and second ends, with the first end being at the lighting end and the grooves being equidistantly spaced apart about the fluted member. Each groove has a maximum depth. The depth maxima of the grooves define a circle having a radius. The maximum depth of each groove is no more than the radius of the circle. A heat generation apparatus for an aerosol-generation system of a smoking article is also provided.

There is provided an aerosol generating article (2). The aerosol generating article comprises a combustible heat source (4) having a longitudinal outer surface, an aerosol-forming substrate (10) downstream of the combustible heat source, and a retaining wrap (35). The retaining wrap comprises a an upstream portion (31) extending at least about 50 percent of the way along the length of the combustible heat source on the longitudinal outer surface of the combustible heat source. The upstream portion of the retaining wrap comprises at least one opening (41, 42) overlaying at least about 30 percent of the longitudinal outer surface of the combustible heat source. The retaining wrap further comprises a downstream portion (33) circumscribing at least a portion of the aerosol-forming substrate.

A machine for making sub-units of smoking articles comprises a conveyor, a feed unit, cutting means and at least one rotary applicator. The conveyor is configured to feed a succession of tubular segments of the tobacco industry. The feed unit is configured to feed and convey at least one continuous web. The cutting means are configured to separate a succession of closing elements from a front end of the continuous web. The rotary applicator is operatively associated with the conveyor and is configured to pick up the succession of closing elements and to apply them, preferably by gluing, to an application end of a respective tubular segment, in such a way as to form closing walls to at least partly close the application ends.

A filling unit, configured to fill a succession of tubular wrappers of the tobacco industry. The tubular wrappers extend along a main axis of extension and internally define respective containment chambers adapted to contain a filling material of the tobacco industry and have an access opening on at least one of its ends for access to the containment chamber. The unit also includes a filling station configured to insert the filling material into respective containment chambers of the succession of tubular wrappers through a filling end of them and a closing station disposed downstream of the filling station and comprising a plurality of closing means configured to make respective walls which close the filling ends and which are transverse to the respective main axes of extension.

The present disclosure is directed to a holder of a smoking article comprising a receiving end and a mouth end opposite the receiving end. The holder defines a socket that is configured to receive a proximal section of a cartridge. The holder has a lighting configuration in which the holder is configured to secure a proximal section of the cartridge to the holder with a heat source of the cartridge opposite the proximal section disposed beyond the receiving end of the holder. The holder has a received configuration in which the holder is configured to secure the proximal section of the cartridge in the socket with the heat source disposed proximate the receiving end of the holder. The receiving end comprises a substantially solid outer wall.

A smoking article is provided, having opposed lighting and mouth ends, and including a mouth end portion at the mouth end. A tobacco portion is between the lighting end and the mouth end portion. An aerosol-generation system is between the lighting end and the tobacco portion. The aerosol-generation system includes a heat generation portion, comprising an elongate fluted member actuated by ignition of the lighting end. The fluted member defines grooves extending longitudinally between opposed first and second ends, with the first end being at the lighting end and the grooves being equidistantly spaced apart about the fluted member. Each groove has a maximum depth. The depth maxima of the grooves define a circle having a radius. The maximum depth of each groove is no more than the radius of the circle. A heat generation apparatus for an aerosol-generation system of a smoking article is also provided.
