Abstract

A length of tube of heat shrinkable plastic is located over a mandrel such that the end of the tube overlaps the end. The overlapping end of the tube is then folded over onto the mandrel and as the tube is heat shrunk around the mandrel and end cap is secured (e.g. by welding) to the overlapping end of the tube. Pref. the length of tube is cut from an extruded plastic tube which has been flattened in two mutually orthazonal planes to form the tube into a square cross-section. This venders the tube self-supporting and makes it easier to fit onto the mandrel. The method is used for forming outer covers over bottle caps in which case the end cap is flat disc. Alternatively if the method is used for making tubes for containing paste the end cap may be frusto-conical and may have at its small dia. end an axially bored flange on which a top can be fitted. The method is cheap and can be easily automated.
