PROBLEM TO BE SOLVED: To provide a novel dispenser head of relatively simple structure which can be fitted to a receptacle containing a substance. SOLUTION: The dispenser head for fitting to a receptacle (2) containing a substance has at least one dispenser orifice (11), and it includes an elastically deformable shutter suitable for taking up at least two different extreme configurations, namely an open configuration enabling the substance in the receptacle to flow toward the dispenser orifice and a closed configuration preventing the substance in the receptacle from flowing toward the orifice. Passage from one extreme configuration to the other is induced by action other than pressure from the substance in the receptacle.
