Abstract

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.

Claims

exact text as granted — not AI-modified
1 . A device for releasing a vapour, the device comprising a first sachet of a vapour releasing substance and a second sachet containing a substance adapted, when by exposure to air, to initiate an exothermic reaction, the heat from said reaction being operative to release the vapour from the substance in the first sachet, characterized in that the first and second sachets are joined together and share a common impermeable wall, and in that additional air-impermeable layers are provided temporarily to seal the sachets until it is desired to activate the device.  
   
   
       2 . (canceled)  
   
   
       3 . A device according to  claim 1 , further comprising a packaging container adapted to be deployed so as to form a holder for the sachets.  
   
   
       4 . (canceled)  
   
   
       5 . (canceled)  
   
   
       6 . (canceled)  
   
   
       7 . A device according to  claim 1 , wherein the exothermic reaction produced by the second sachet reaches an average temperature of around 40-70° C. after about 1.5 to 2 hours.  
   
   
       8 . A device according to  claim 7 , wherein the exothermic reaction reaches a temperature of around 55° C.  
   
   
       9 . A device according to  claim 7 , wherein the exothermic reaction lasts for around 6 to 8 hours.  
   
   
       10 . A device according to  claim 1 , wherein said first sachet contains a plurality of beads or granules impregnated with the said vapour-releasing substance.  
   
   
       11 . (canceled)  
   
   
       12 . A device according to  claim 3 , wherein said container comprises a box having a first lid portion adapted to close the box and a second lid portion adapted to be folded over the top of the first lid portion in spaced relation so as to create a space adapted to receive the mitt, sleeve or pouch when the device is activated.  
   
   
       13 . A device according to  claim 1 , wherein said vapour released by said releasing substance comprises a decongestant.  
   
   
       14 . A device according to  claim 1 , wherein said vapour released by said releasing substance comprises an insect repellent.  
   
   
       15 . A device according to  claim 1 , wherein said vapour released by said releasing substance comprises an insecticide.  
   
   
       16 . A device according to  claim 1 , wherein said vapour released by said releasing substance comprises an aromatherapy agent.  
   
   
       17 . (canceled)  
   
   
       18 . (canceled)
