Formulating pasty materials.

摘要

Two or more pasty materials may be accurately formulated together by sequentially extruding the desired amounts of those materials into a tube (5) with graduations (7) associated with it to measure the amounts extruded. After the components have been put serially into the tube (5), they are removed from the tube, e.g. by squeezing the tube and moving the squeeze towards one end, and mixed to homogeneity. Preferably the mixing takes place in a container on to which a lid may be put and from which the mixture may then be extruded. e.g. by having a movable base on the container which then acts as a piston to extrude the mixed formulated paste through a nozzle in the lid.
