The invention relates to the covering with sheet material of flexible symmetrical angulate tubes, especially components of packages. By utilizing the resilient cross-sectional deformability of the tubes, there is provided a method and apparatus where the tube is mounted onto a cylindrical mandrel having a circumference corresponding essentially to the inner circumference of the tube and thereafter applying the sheet material around essentially the entire circumference of the tube.

Method and apparatus for covering flexible symmetrical angulate tubes

A container closure of the composite type comprising a supporting and protecting part of plastics, having a central panel and a circumferential flange, and a thin metal foil acting as sealing label, attached to said part. A tearing denotation is formed in a multi step injection moulded weld zone and a sealing label is arranged to cover at least the weld zone of the container part. The weld zone includes abutment surfaces of the sequentially moulded parts acting as stop members preventing free relative movement between said parts after the weld zone is broken.
