Abstract

553,398. Collapsable tubes. BETTS & CO. Ltd., and DUNN, E.. STATHFR-. March 11. 1942, No. 3200. [Class 66] [Also in Group XXII] A collapsable tube is made by inserting a small mass of tin or other non-staining metal in a hole in a tin-coated lead disc and then extruding the disc to form a tin-coated lead collapsable tube with a nozzle of non-staining metal. The insert may be welded to the disc before extruding, for instance, by casting it into the hole in the disc.
