Definitions

  • a cooling element e.g. a cooling element for a tobacco heated product and/or HNB product
  • a longitudinally extending core of (e.g. thermoformed) cellulose acetate material comprising a longitudinally extending core of (e.g. thermoformed) cellulose acetate material; the longitudinally extending core of cellulose acetate material having a profiled outer surface including a plurality of (e.g. longitudinally extending) (e.g. C-shaped or U-shaped) grooves or channels of depth (e.g. maximum depth) 0.5 to 2.6 mm which extend the full length of the (outer surface of the) core.
  • a plurality of (e.g. longitudinally extending) e.g. C-shaped or U-shaped) grooves or channels of depth (e.g. maximum depth) 0.5 to 2.6 mm
  • the hollow tubular element may have walls of thickness 0.3 mm to 5.5 mm, for example 0.4 to 5.5 mm, for example 0.5 to 2.5 mm, preferably 1 to 2 mm.
  • the hollow tubular element may have walls of thickness 0.4 to 1.0 mm.
  • the hollow tubular element may have walls of thickness 1.0 to 5.5 mm.

  • Cooling element 40’ comprises a longitudinally extending core of thermoformed cellulose acetate material of length 18mm.
  • the longitudinally extending core of cellulose acetate material is thermoformed with a profiled outer surface including five longitudinally extending channels or grooves 90’ of generally shallow U-shaped cross section with maximum depth 1.80 mm and width 1.5 mm which extend the full length of the core.
  • the five channels 90’ are spaced equidistantly around the perimeter of the profiled outer surface (as can be seen from Fig 3).
  • the longitudinally extending core of cellulose acetate material is of uniform axial cross section, as shown in Figure 3. It will be appreciated that the cross section of the cooling element 40’ can be considered to be generally circular with five shallow U-shaped grooves or channels 90’ disposed equidistantly about its perimeter.
