A collapsible dispensing tube has a multi-layer sheet material sealed over its dispensing orifice to provide a hermetically sealed tube. The multi-layer sealant sheet comprises two layers of metal foil separated by a polymer layer firmly adhered to the metal foil layers. A polymeric layer is adhered to the outer surface of one of the metal foil layers and serves to seal the tube orifice. The laminated sheet may be sealed across the orifice by the application of radio-frequency energy.

A method and apparatus for processing of workpieces comprising the steps of continuously transferring the workpieces to and fro among a plurality of rotating members, wherein each member carries a plurality of sets of work stations. Workpieces, such as precut tubular sleeves, and tube heads, are sealed to form containers, utilizing continuously rotating turrets and cooperating rotating members designed to produce such containers efficiently and at high rate of production.

Material handling method and apparatus therefor

A laminate of non-ferrous metal foil and heat softenable material is folded to tubular form to juxtapose the margins and the margins are heat sealed by passing the tube through an inductance coil; the inductance field may be intensified by a ferrite bar located in a mandrel over which the tube is fed.
