The dispensing head (1), made with two parallel sleeves (11, 12) forming inlets (110, 120) for hollow actuating rods linked to pumps or valves on two containers, and a nozzle (13) with ducts (131, 132) and outlets (1310, 1320), has a crosspiece (10) connecting the sleeves to the nozzle. The crosspiece contains at least one duct (101, 102) linking the inlets to the outlets and extending transversely relative to the sleeves and the nozzle outlet ducts. Each transverse duct has an access port (1010, 1020) at its outer end, closed by a stopper (141. 151). |
