Abstract
A method for making a lid with a spout is disclosed. The spout is affixed in an opening of the lid by injection molding the lid about the spout while the spout is held in place in the injection mold. The steps of molding the lid and affixing the spout to the lid are performed at the same time without the detriments of conventional ultrasonic welding. Preferably, a core insertion member is used in a movable base mold and a cavity insertion member is used in a fixed base mold to hold the spout in place and to mold the lid thereabout.
