Abstract
The invention relates to a device for dispensing fluid products which is provided with an extension tip (4) connected by a first end to a nozzle (3) associated with a metering pump mounted on a bottle containing the product that is to be dispensed and comprising at its distal second end a discharge orifice, said extension tip (4) bearing a shutter (5) a first end (5A) of which is arranged on said discharge orifice, this shutter (5) being intended to open at its distal second end (5B) under the pressure of the product when said pump is actuated, and said shutter (5) comprising a tubular external part (6), elastically deformable in longitudinal bending, of which a first end (5A) is arranged on the discharge orifice and of which the tapering external cross section diminishes evenly towards its distal second end (5B), at least over part of its length, said external part (6) being intended to deform elastically in a radial direction at its distal second end (5B) under the pressure of the fluid leaving the pump via said nozzle (3).According to the invention, said shutter (5) comprises, inside said external part (6), a tubular connector (7) secured to said discharge orifice of the tip (4)…
