| 摘要 |
A device for releasing a vapour comprises a first sachet of a vapour releasing substance and a second sachet containing a substance adapted, when activated, to initiate an exothermic reaction, the heat from the reaction being operative to release the vapour from the substance in the first sachet. The sachets may be inserted into a mitt, sleeve or pouch adapted to receive a first sachet on top of a second sachet. A packaging container 1 for the device is adapted to be deployed so as to form a pocket between lids 3, 4 to accept the mitt, sleeve or pouch. The exothermic reaction produced by the second sachet reaches an average temperature of around 40-70° C. after about 1.5 to 2 hours. The first sachet contains beads or granules impregnated with the vapour-releasing substance, which may be a decongestant or an insecticide or may be for ambience or aromatherapy use.
