ABSTRACT OF THE DISCLOSURE A method and apparatus for joining to a cylindrical container sleeve a sealing or closure element. The sealing element is provided with a circular collar arranged to be inserted into one open end of the container sleeve and into abut- ment with the inner wall thereof. The collar comprises a heat- meltable plastics material and the sealing or closure element is mounted on the container sleeve with the collar in abutment with the inner wall of said sleeve. The container sleeve and the sealing or closure element are rotated around the cylinder axis of the sleeve and a heated body, whose temperature exceeds the melting point of the plastics material in the collar, is pressed against the collar. The container sleeve is rotated until the plastics material in the collar has melted and the heated body is then removed out of contact with the plastics material to permit the plastics material to solidify.
