Abstract
A fluid product spray head (40) comprises a spray orifice (45) and a spray profile (100) upstream from this spray orifice (45). Said spray profile has a swirling chamber (101) connected, during the spraying of the product, to the spray orifice (45) and to at least one non-radial channel (110) connected to the swirling chamber (101). The spray profile (100) is provided in the bottom of the spray head (40). A obturator (38) interacts with the spray orifice (45) while being able to be displaced and/or deformed between a closing position of the spray orifice (45) and an open position of the spray orifice (45). The inventive spray head (40) has an axially hollow sleeve (150) that accommodates the spray profile (100), and said obturator (38) axially displaces and/or deforms at least partially in said sleeve (150).
