Device and set for the dispensing of hair dye

A device ( 1 ) comprises a reservoir ( 2 ), preferably having a transparent wall ( 8 ), for holding a flowable product ( 3 ) and a dispensing head ( 4 ) for discharging the product ( 3 ). The dispensing head ( 4 ) is joined to the reservoir ( 2 ) via a coupling ( 5 ), especially a threaded coupling. Provided on dispensing head ( 4 ) is an actuator device ( 6 ) for opening and closing the dispensing head ( 4 ) as desired in order to dispense product accordingly from a discharge opening ( 18 ). In order to prevent erroneous refilling with product when an empty reservoir ( 2 ) is replaced with a full reservoir ( 2 ), especially when there is a set of reservoirs ( 2 ) having different products ( 3 ) for coloring hair, it is proposed that the product ( 3 ) be a powdered or granulate hair dye and that the surface of the dispensing head ( 4 ) or the actuator device ( 6 ) have an information surface ( 7 ) that is to be assigned to the product ( 3 ). The powder or granulate form thus serves to ensure recognition of the color of the product ( 3 ).
