ABSTRACT:
A plastic container for pourable liquids such as detergents has a drain back feature and has an internal thread for receiving an externally threaded cap which also serves as a measuring cup for the liquid. The container is formed in two pieces, a container body and a separately formed pour spout component which is assembled to the container finish preferably by ultrasonic welding. In preferred embodiments a lip of the pour spout component is pressed and welded down onto an annular top surface of the container finish, or down into an annular recess on the container finish. The ultrasonic welding operation is accompanied by motion and pressure, simultaneously deforming and welding the top edge of the pour spout component wall down onto the container finish, so that the connection forms a liquid tight seal.
