Abstract
Apparatus for formulating pasty materials comprising a set of supply containers each containing a pasty material and each having an extrusion nozzle. A receiving tube is adapted to fit on each extrusion nozzle. An element is included for stimating the amount of material extruded from a selected container of the set into the receiving tube when the tube is fitted on one of the extrusion nozzles. The receiving tube is of flexible material to allow pasty material extruded into the tube to be ejected from the tube by application of a traveling pinching action along the tube. The apparatus may include a container for the receipt of such ejected material and an element for stirring or mixing to homogeneity material in the container.
