Abstract
Abstract In a process and apparatus for joining a tubular thermoplastic container jacket, by means of ultrasonics, to a thermoplastic end cap to form a liquid-tight seal, the end cap is inserted into the jacket so that the jacket rim projects beyond the cap, and an axially-oscillating sonotrode is advanced axially against the jacket rim to soften the jacket rim and roll it inwardly over the rim of the cap. The softened jacket rim is trapped in an annular chamber formed between the sonotrode and the cap, and further advancement of the sonotrode applies welding pressure to the softened jacket rim.
