Container for volatile substances

Abstract

The invention refers to a container ( 1 ) for volatile substances having a first chamber ( 2 ) containing a porous material ( 4 ) impregnated with a first volatile substance, and a second chamber ( 3 ) containing a second volatile substance. The evaporation of the first and the second volatile substances is synchronized so that both volatile substances are finished substantially at the same time. The second volatile substance is used as a visual indication of the end of life of the first substance. The open base of the first and the second chamber are covered by a permeable film. The container may be arranged with a heater for the volatile substances.

1 . Container for volatile substances having a first chamber containing a porous material impregnated with a first volatile substance, and a second chamber containing a second volatile substance, and wherein the container is configured to allow the evaporation of said volatile substances. 
   
   
       2 . Container according to  claim 1  wherein the evaporation of the first and the second volatile substances is synchronized so that both volatile substances are finished substantially at the same time. 
   
   
       3 . Container according to  claim 1  or  claim 2  wherein the first and the second chambers have an open base. 
   
   
       4 . Container according to any of the preceding claims wherein the open base of the second chamber is covered by a permeable film. 
   
   
       5 . Container according to any of the  claims 1  to  3  wherein the open base of the first and the second chamber are covered by a permeable film. 
   
   
       6 . Container according to any of the preceding claims wherein the second volatile substance is a liquid or a gel. 
   
   
       7 . Device for the evaporation of volatile substances including a container according to any of the preceding claims. 
   
   
       8 . Device according to  claim 7  comprising heating means arranged to heat said volatile substances.
