Device for dispensing and dosing a product, comprising a first valve disposed across the aperture of the receptable; a slide system comprising a fixed part and a movable part including a piston sliding into a zone of said fixed part delimiting externally a dosing chamber, said piston having therethrough a passage for the communication of said dosing chamber with the outside; and a second valve associated with said piston for opening the communication between said dosing chamber and the outside when said piston slides down for compressing the product contained in said chamber and closing off said communication when the piston is slides up.

A device for dispensing and dosing a product contained in a receptacle having an outlet aperture upon which the device is mounted, the device comprising: a first valve disposed over the aperture; a slide system having a fixed part and a movable part which penetrates into a zone of the fixed part, the zone outwardly defining a chamber for dispensing a dose of the product, the system including a piston which is movable in the zone which includes a discharge passage passing therethrough, allowing the chamber to communicate with the outside; a first movement of the piston opening the first valve to allow dosed product to be dispensed from the receptacle to the dosing chamber; a second movement of the piston being in a reverse direction from the first movement and pressurizing the product contained in the chamber thereby forcing the product to be dispensed to the discharge passage while checking return of product to the receptacle by closure of the first valve; a second valve associated with the piston for closing the communication through the discharge passage, at least at the end of the first piston movement, while opening the communication during the second piston movement; and means for delivering a complete for partial dose of product contained in the dosing chamber.
