ABSTRACT:
A foaming head (10) has a discharge nozzle (12), the discharge channel (14) of which has at the upper end a tubular section (16), the upper end of which is closed by a deflecting plate (18) and is provided with passage slits (22) which open out radially into an outlet slit (24) in the head wall (20). An inner base (26) of each outlet slit (24) extends radially outwardly from the lower end (28) of each passage slit (22) as far as a deflecting wall (30) which together with the discharge channel (14) forms an acute angle which opens towards the head wall (20). An upper end (32) of each deflecting wall (30) is arranged at a level which is approximately two-thirds of the height of the tubular section (16). An outer base (34) of each outlet slit (24) extends radially outwardly from the upper end (32) of the deflecting wall (30) as far as the vicinity of an outer edge (36) of the head wall (20). The foaming head can be produced economically as a one-part plastics injection molding and, with an extremely simple construction, permits outstanding foaming of a foamable product contained in a pressure container.
