Cap for a container containing a volatile air treatment agent

Abstract

This invention relates to an air treatment device using a volatile treating agent contained inside of a permeable container ( 1 ) and a cap ( 4 ) closing the container ( 1 ). The cap ( 4 ) comprises a reservoir ( 12 ) containing the active agent.

1 . Cap ( 4 ) for a container ( 1 ) comprising an interior wall ( 14 ) and a bottom ( 16 ), characterised in that the interior wall ( 14 ) and the bottom ( 16 ) form a reservoir ( 12 ).  
   
   
       2 . Cap of  claim 1 , characterised in that the interior wall ( 14 ) is cylindrical.  
   
   
       3 . Cap ( 4 ) as claimed in  claim 1  or  2 , characterised in that the reservoir ( 12 ) is sealed off from the outside environment by an inner seal ( 18 ).  
   
   
       4 . Cap ( 4 ) as claimed in one of  claims 1  to  3 , characterised in that the reservoir ( 12 ) contains a treating agent.  
   
   
       5 . Cap ( 4 ) of  claim 4 , characterised in that the interior wall ( 14 ) and the bottom ( 16 ) have thicknesses defined so as to prevent the migration of the treating agent towards the exterior of the reservoir.  
   
   
       6 . Air treatment device using a volatile treating agent contained inside of a permeable container ( 1 ) and a cap ( 4 ) closing the container ( 1 ), characterised in that the device comprises a cap ( 4 ) as claimed in of the preceding claims.  
   
   
       7 . Air treatment device of  claim 6 , characterised in that the reservoir ( 12 ) is closed by an inner seal ( 18 ).  
   
   
       8 . Air treatment device of  claim 7 , characterised in that the device comprises perforating means ( 30 ,  40 ) suitable for piercing the inner seal ( 18 ).  
   
   
       9 . Air treatment device as claimed in one of  claims 6  to  8 , characterised in that the device comprises a body ( 2 ) for supporting the treating agent.  
   
   
       10 . Air treatment device of  claim 9 , characterised in that permeable container ( 1 ) comprises ribs ( 20 ) that clamp tightly around the body ( 2 ).  
   
   
       11 . Air treatment device as claimed in one of  claims 6  to  10 , characterised in that the cap ( 4 ) occupies at least a first and a second position in relation to the permeable container ( 1 ).  
   
   
       12 . Air treatment device as claimed in one of  claims 6  to  11 , characterised in that the permeable container ( 1 ) comprises a wall ( 22 ) having in interior face including at least one indexing groove ( 24 ,  26 ).  
   
   
       13 . Air treatment device of  claim 12 , characterised in that the cap ( 4 ) comprises an exterior wall ( 17 ) including a boss ( 28 ) cooperating with the indexing groove ( 24 ,  26 ) in order to define various positions of the cap ( 4 ) in relation to the permeable container ( 1 ).  
   
   
       14 . Air treatment device as claimed in one of  claims 6  to  11 , characterised in that the permeable container ( 1 ) comprises a wall ( 22 ) having an interior face including a internal thread cooperating with a thread made on an exterior wall ( 17 ) of the cap ( 4 ), in order to screw the cap ( 4 ) into the permeable container ( 1 ).  
   
   
       15 . Air treatment device as claimed in one of  claims 11  to  13 , characterised in that shifting from the first position to the second position is done by transversely displacing the cap ( 4 ) in relation to the permeable container ( 1 ).  
   
   
       16 . Air treatment device of  claim 14 , characterised in that shifting from the first position to the second position is done by rotating the cap ( 4 ) in relation to the permeable container ( 1 ).  
   
   
       17 . Air treatment device as claimed in one of  claims 11  to  16 , characterised in that the first position, referred to as the high position, is such that the seal of the reservoir ( 12 ) is preserved, and in that the second position, referred to as the low position, is such that the seal of the reservoir ( 12 ) is broken.  
   
   
       18 . Air treatment device of  claim 17 , characterised in that the seal of the reservoir ( 12 ) is broken by perforating means ( 30 ,  40 ).  
   
   
       19 . Air treatment device of  claim 17 , characterised in that the perforating means are made from the body ( 2 ) comprising a perforator ( 30 ) at its upper portion.  
   
   
       20 . Air treatment device of  claim 17 , characterised in that the perforating means are made by an additional perforator ( 40 ) mounted inside the permeable container ( 1 ) .  
   
   
       21 . Air treatment device of  claim 20 , characterised in that the perforator ( 40 ) rests on the ribs ( 20 ) of the permeable container ( 1 ).
