Abstract
A container which comprises a tubular body made of paperboard or of a laminate including paper has its ends closed by closure members made of a different material such as tinplate or a plastics material. Each closure member includes a plug portion which closely engages an end part of the body and a rim which extends laterally from the plug portion and is disposed to be closely adjacent to the end face of the body. At at least one end of the body the closure member therefor is at least in part secured to the body by a continuous band of thermoplastics material which extends lengthwise of the plug portion and forms at the inner end of the plug portion a bead arranged to caulk the leak path between the body and the plug portion to the rim.
