Abstract:
Device for distributing predetermined quantities of liquid and/or pasty products, this device including:a) two superimposed receptacles integral with each other and communicating with each other via an orifice fitted at the bottom of the first receptacle, namely: an upper receptacle closed by a cover and used as a tank for the product to be distributed, and a lower smaller receptacle constituting a cylinder whose bottom is provided with an outlet; b) a piston which slides sealed inside said cylinder between an upper intake position and a bottom distribution end of travel position, this piston being traversed by at least one orifice and stressed by first elastic means towards its upper intake position, including: c) a clack valve integral with a rod for activating the piston and mobile between the opening and closing positions of said orifice, this clack valve being stressed by second elastic means towards its opening position; d) a distribution nozzle in communication with the cylinder via an orifice equipped with a sealing seat against which an obturator, normally kept in a closed position, is housed in said nozzle under the effect of a spring, and e) means for activating the rod from outside said receptacles making it possible to successively obtain from an initial state where the piston is in the upper intake position, the clack valve in its open position and the obturator in its closed position; the closing of the clack valve then the movement of the piston towards its distribution end of travel position with at the same time opening of the obturator and distribution of the product, immobilisation of the piston at the end of travel with closing of the obturator, opening of the clack valve, then the return on the piston into its upper intake position with simultaneously sucking up of the product contained in the receptacle inside the cylinder.
