    摘要: An emanation device comprises an emanation material container (10), an emanation section (20) and emanation material level indication means (14,16); wherein, the emanation material level indication means (14, 16) comprises a light source (14), a light detector (16) and control means (not shown), wherein the light detector (16) is adapted to receive light from the light source (14) when a level of emanation material in the emanation material container (10) is at a first level and wherein the light detector (16) is adapted to receive substantially no light from the light source (14) when a level of emanation material in the emanation material container (10) is at a second level.

    摘要: A device for vaporising a substance comprises a vaporising chamber having a closure (14) and a vent (42, 44) for allowing vapour to exit the device. In use, a reservoir of substance to be vaporised is introduced into the vaporising chamber. The closure (14) is movable between an open position in which a user is able to introduce the reservoir of substance to be vaporised into the vaporising chamber, and a closed position. The closure (14) is provided with means (46) for opening the reservoir such that the reservoir is opened by the action of moving the closure (14) from the open position to the closed position. The means (46) for opening the reservoir (14) may be a projection (46) extending from an inwardly facing surface of the closure (14).
