A mixing and distributing device for a two constituent product, notably for the formation of a foam in situ, comprises a first and a second interfitted compartment having an inner end and an outer end separated by a web. Means are provided for tearing said web under the effect of the axial approach movement of said compartments through their inner ends, the walls of the latter including complementary threads designed to cooperate to bring about said approach. Each compartment comprises a solid portion and a hollow portion in the form of a substantially semicylindrical trough bounded by a longitudinal surface, the first compartment comprising a removable plug at its outer end and said web at its inner end, said second compartment being closed at its outer end and provided at its other end, on the one hand, with a peripheral projection forming a cutting-out knife for the web and, on the other hand, an axial tit projecting with respect to the inner end of its solid portion.
