Zusammenfassung: | A simulated cigarette comprising a housing 1, a reservoir 4 of inhalable composition within the housing where the inhalable composition comprises nicotine or a pharmaceutically acceptable derivative or salt thereof, an inhalation outlet 2, for the inhalable composition, from the reservoir and leading out of the housing, and a breath-activated inhalation outlet valve 5 for controlling the flow of inhalable composition through the inhalation outlet, wherein at least one part of the simulated cigarette that comes into contact with the inhalable composition during the use comprises one or more of: polyoxymethylene, polybutylene terephthalate, polytetrafluoroethylene, ethylene propylene diene monomer rubber and a thermoplastic elastomer. The inhalable composition preferably comprises less than 50 µg/m3 of formaldehyde and/or less than 180 µg/m3 acetaldehyde and the inhalable composition may comprise one or more of monohydric alcohol and a glycol and/or glycol ether. Ideally the reservoir is pressurised and the internal walls of the reservoir may comprise polybutylene terephthalate. The reservoir may be refillable and comprise a refill valve at a refill end opposite the outlet end. The refill valve preferably comprises a refill valve element 10, a spring 11 and a cage 12. |
