A dispenser head (104) is fitted on two separate reservoirs which are disposed side-by-side and on the outlet openings whereof, dispenser valves are disposed. The head (104) comprises a first part (113) which cooperates simultaneously with the two valves with a view to producing the ejection of each one of the constituents into an ejection duct which passes through it. The second part of the head is complementary to the first part so as to constitute in the assembled position of the two parts, a mixing chamber (134) into which there open the two ducts (121a, 121b). The mixing chamber opens out to the outside of the head. Deflectors (136) may be carried by one of the parts (113, 114) in the mixing region of the chamber (134) to improve the mixing of the material dispensed from the two reservoirs.

A head for dispensing doses of a product of a pasty or viscous consistency resulting from the mixing in the head of two constituents stored in separate side-by-side reservoirs each provided with a dispensing outlet element, said head being comprised of a first and a second part fitted to each other, said first part having a pair of ejection ducts passing therethrough and being provided with means adapted to cooperate simultaneously with the two dispensing outlet elements for causing the ejection of the contents of the reservoirs into respective ones of said ejection ducts, said first and second parts having complementary means carried thereby to cooperate to define a mixing chamber in the assembled position of the two parts, said ejection ducts opening into said mixing chamber at spaced locations, and said mixing chamber having a single outlet opening for the dispensing of a mixture of material admitted to the chamber from the two ducts, said first and second parts having mutually facing respective walls integral with said respective part, one of said walls having a continuous rib carried thereon extending substantially perpendicular therefrom and the other of said walls having a groove formed therein of a shape complementing the external contour of said rib, said mixing chamber being located between said walls and said rib being received in said groove with said rib having a height from said respective wall such that said rib defines the side walls of said mixing chamber when said first and second parts are assembled.
