Title: Multiple-tube dispenser

Abstract: A multiple-tube dispenser contains components of a composition to be prepared by mixing the components at a fixed ratio. The tube cylinders are interconnected by a web and each have a discharge opening at their front end. Pistons provided in the tube cylinders are advanced in unison by plungers extending into the tube cylinders and interconnected by a common head portion. A threaded spindle extends through a bore provided in the head portion and engages a threaded bore provided in the web interconnecting the tube cylinders. The two bores are slotted in a direction perpendicular to the spindle axis so that the spindle may be inserted and removed at any position of the plungers relative to the tube cylinders. The web interconnecting the cylinders is made preferably of synthetic material and the bore in this web has an initially smooth inner surface in which the counter-thread is automatically tapped when the threaded spindle is inserted.
