It also comprises a substance detectable by irradiation or in the presence of a suitable reagent, said substance being applied, deposited or incorporated on or in at least one constituent part of the dispenser.

What is claims is:  
     
         1 . Fluid product dispenser comprising the following constituent parts: 
 a container ( 1 ) forming an opening ( 10 ),    a dispensing device ( 2 ) fitted in the opening ( 10 ),    an actuation device ( 3 ) to actuate the dispensing device,    characterised in that it also comprises a substance detectable by irradiation or in the presence of a suitable reagent, said substance being applied, deposited or incorporated on or in at least one constituent part of the dispenser.    
     
     
         2 . Dispenser according to  claim 1 , wherein the detectable substance is invisible in the ambient atmosphere in visible light.  
     
     
         3 . Dispenser according to  claim 2 , wherein the detectable substance is an invisible ink capable of being detected when subjected to a given electromagnetic wave.  
     
     
         4 . Dispenser according to  claim 1 , wherein the detectable substance is detected when subjected to a heat source.  
     
     
         5 . Dispenser according to  claim 1 , comprising at least one metal constituent part ( 4 ,  32 ,  13 ) treated by anodic oxidation or anodisation to dye it with a dye, said detectable substance being added to the dye.  
     
     
         6 . Dispenser according to  claim 5 , wherein said anodised part is a metal attachment cap ( 4 ) used to attach the dispensing device ( 2 ) in the opening ( 10 ) of the container ( 1 ).  
     
     
         7 . Dispenser according to  claim 5 , wherein said anodised part is a metal coating of a pushing device ( 32 ), plastic attachment ring or container ( 13 ).
