Abstract:
A spray head for fixing to a control rod of a valve or a pump, the spray head comprising a body and a shutter disposed in a housing of said body, the housing being suitable for communicating, in use, with a source of substance under pressure, the shutter being arranged at rest to take up a closed position in which it rests via a frustoconical head portion against a frustoconical bearing surface of said body, and being suitable for moving off said bearing surface under the effect of the pressure of a substance contained in said housing while dispensing the substance, thereby forming an annular dispenser orifice enabling the substance to be dispensed in the form of a hollow conical spray, at least in the vicinity of the head, the shutter moving away from said bearing surface against a resilient return action tending to urge it back into the closed position when the pressure of the substance diminishes.
