ABSTRACT:
A container is manufactured by placing a length of extruded thermoplastic tubing over a mandrel so that an end of the tubing extends beyond the mandrel to form an annular rim and placing a thermoplastic slug on the mandrel within the rim. An ultrasonic resonating horn is provided having a cavity adapted to receive the rim. The horn cavity has a base and an annular tapered portion formed around the base and engageable with the rim. The tubing and the resonating horn are pressed together with a relatively moderate force so that the tapered portion of the horn cavity engages the rim of the tubing and softens and folds it inwardly in such a manner that it is in alignment with the slug, the mandrel, and the base of the cavity. The mandrel and the resonating horn are then brought together with a relatively large force to squeeze the folded rim and the slug tightly together between the mandrel and the base of the cavity. Ultrasonic waves propagated from the horn into the folded rim and the slug fuse the rim and the slug together to form a watertight seal at the end of the tubing. Thereafter, a different mandrel and a different ultrasonic resonating horn are employed to fuse a stand to the sealed end of the tubing.
