ABSTRACT:
The container (1) is provided with a spring closure device, the container being provided with an outlet channel (12) for the product ending in an orifice (14), the orifice being closed with the aid of a membrane (2) of flexible material which is deformed under the pressure of the product to be dispensed. The membrane (2) is provided both with a pin (22) capable of covering the orifice (14) and with openings (23) which, if there is no deformation of the membrane (2), remain closed by virtue of the elastic properties of the membrane (2).
