Device and method for co-metering
A device for co-metering liquid and/or pasty products includes: a first metering unit for metering a first product; a second metering unit for metering a second product; and a nozzle including a first duct supplied by the first metering unit and opening out into a first orifice, a second duct supplied by the second metering unit and opening out into a second orifice, and a third duct opening out into a third orifice. The device is configured such that the third duct is supplied by the first and second metering units such that a mixture of the first and second products is discharged by the third orifice.
1. A device for co-metering liquid and/or pasty products, the device comprising:
a first metering unit for metering a first product;
a second metering unit for metering a second product; and
a nozzle including a first duct supplied by the first metering unit and opening out into a first orifice, and the nozzle further including a second duct supplied by the second metering unit and opening out into a second orifice,
the nozzle is configured to separately dispense the first product, the second product, and a mixture thereof out of the nozzle, and
the nozzle further comprises a third duct opening out into a third orifice, the device being configured such that the third duct is supplied by the first and second metering units, such that a mixture of the first and second products is discharged by the third orifice.
2. The device according to claim 1 comprising a third metering unit connected to a fourth duct of the nozzle, the fourth duct opening out into a fourth orifice.
