摘要

A container sleeve 1 having an inner coating 5 of a heat weldable plastics material is fitted with a closure element 2 having a collar 4 of meltable plastics material. The assembly is rotated while a hot welding shoe 35 is inserted through the open end of the sleeve and brought to bear against the collar, which melts the latter and fuses it to the tackified coating 5 to thereby provide a tightly sealed joint.
