  • Each electrical connector 230a, 230b may be arranged to provide electrical power to a respective resistive heating arrangement 340 of a first and a second aerosol generator 304, wherein the resistive heating arrangements 340 are located on opposites sides of the article 300 to one another.
  • Figure 35 are configured such that when the article 300 is inserted into the article receiving portion 206, a first connector electrical contact of the plurality of connector electrical contacts, e.g. the second connector electrical contact 232b, engages the continuous length of electrically conductive material 385 at an engagement portion - e.g. a second engagement portion 323b encompassing the second end 384a of the first resistive heating portion 380a and the first end 382b of the second resistive heating portion 380b. It can be seen that the engagement portion 232b encompassing the second end 384a of the first resistive heating portion 380a and the first end 382b of the second resistive heating portion 380b provides an article electrical contact.
  • the third connector electrical contact 232c engages a third engagement portion 323c encompassing the second end 384b of second resistive heating portion 380b and the first end 382c of the third resistive heating portion 380c.
  • the fourth connector electrical contact 232d engages a fourth engagement portion 323d encompassing the second end 384c of the third resistive heating portion 380c and the first end 382d of the fourth resistive heating portion 380d.
  • the fifth connector electrical contact 232e engages the fifth engagement portion 392e encompassing the second end 384d of fourth resistive heating portion 380d and the first end 382e of the fifth resistive heating portion 380e.
  • the first and sixth connector electrical contacts 232a and 232f engage a first engagement portion 323a and a sixth engagement portion 323f respectively.
  • Each of the first to sixth engagement portions 323a-323f may be considered to provide article electrical contacts.
  • the first to sixth connector electrical contacts 232a-232f may be suitable shaped and/or dimensioned such that they only contact the relevant first and/or second ends (i.e. the first to sixth engagement portions 323a-323f) of the resistive heating portions 380a- 380d.
  • each resistive heating portion 380 may be arranged adjacent one another such that the first end 382 and second end 384 of each resistive heating portion 380 in the plurality of resistive heating portions are all located on the same side of the article 300. In being located on the same side of the article 300 this may mean that the first end 382 and second end 384 of the resistive heating elements 342 and/or resistive heating portions 380 are arranged along one edge of the article 300. In some embodiments, e.g.
  • each resistive heating element 342 or resistive heating portion 380 may extend across a length of the article 300 from a first edge of the resistive heating arrangement 340 to a second opposing edge of the heating arrangement 340 in a first direction, and extend back across the length of the article 300 from the second edge of the resistive heating arrangement 340 to the first edge of the resistive heating arrangement 340 in a direction which is parallel to the first direction.
  • Paper reconstituted tobacco refers to tobacco material formed by a process in which tobacco feedstock is extracted with a solvent to afford an extract of solubles and a residue comprising fibrous material, and then the extract (usually after concentration, and optionally after further processing) is recombined with fibrous material from the residue (usually after refining of the fibrous material, and optionally with the addition of a portion of non-tobacco fibres) by deposition of the extract onto the fibrous material.
  • the process of recombination resembles the process for making paper.

Abstract

Sont prévus un système de fourniture d'aérosol (100), un article (300) et un dispositif de fourniture d'aérosol (200). L'article comporte un matériau de génération d'aérosol (302) et un agencement de chauffage résistif (340) comportant une pluralité de parties de chauffage résistif (380a-380d), chaque partie de chauffage résistif (380a-380d) comprenant une longueur de matériau électroconducteur présentant une première extrémité (382a-382d) et une seconde extrémité (384a-384d). Le dispositif de fourniture d'aérosol (200) comporte une partie de réception d'article (206) façonnée pour recevoir l'article et un connecteur électrique (230). Le connecteur comporte une pluralité de contacts électriques de connecteur (232a-232e). L'agencement de chauffage résistif et le connecteur électrique sont configurés de telle sorte que, lorsque l'article est introduit dans la partie de réception d'article, un contact de la pluralité de contacts électriques de connecteur est en connexion électrique avec à la fois une seconde extrémité d'une première des parties de chauffage résistif et une première extrémité d'une deuxième des parties de chauffage résistif.
