An end component for a spin welded container comprises a plug which is received within the container side wall for spin-welding thereto. An annular bead co-operates with a step on the wall to locate the plug. During welding, flash generated at the main weld area below the bead is prevented from escaping upwardly by the bead. A cavity is provided above the bead to retain any material which passes the bead or is formed by melting of the bead. |
