SIMULATED CIGARETTE
A simulated cigarette includes a housing having a generally cigarette-like shape and size; a reservoir of inhalable composition within the housing; an actuator controlling the flow of the inhalable composition from the reservoir; an outlet passage from the actuator to an outlet in the housing from which outlet a user inhales the composition; and a chemical heater provided adjacent to the outlet passage and arranged to be activated to undergo an exothermic reaction to heat the inhalable composition as it travels along the outlet passage.
1 . A simulated cigarette comprising:
a housing having a generally cigarette-like shape and size;
a reservoir of inhalable composition within the housing;
an actuator controlling the flow of the inhalable composition from the reservoir;
an outlet passage from the actuator to an outlet in the housing from which outlet a user inhales the composition; and
a chemical heater provided adjacent to the outlet passage and arranged to be activated to undergo an exothermic reaction to heat the inhalable composition as it travels along the outlet passage.
2 . A simulated cigarette according to claim 1 , wherein the actuator is at least 4 mm from the outlet.
3 . A simulated cigarette according to claim 1 , wherein the heater is provided by a gel or liquid which is supersaturated and which is arranged to come into contact with nucleation sites upon tapping of the cigarette, to form crystals and undergo an exothermic reaction.
4 . A simulated cigarette according to claim 3 , wherein there are a plurality of compartments containing liquid or gel which are separately actuatable to produce an exothermic reaction.
5 . A simulated cigarette according to claim 4 , wherein the compartments are rupturable microcapsules.
6 . A simulated cigarette according to claim 1 , wherein the heater is configured to direct the heat produced inwardly, so as to heat the inhalable composition in the outlet passage.
