Zusammenfassung:	A product, e.g., insulated beverage bottle having a lid, and method of making it are disclosed. The product includes an outer hollow blow molded vessel in which an inner hollow blow molded vessel, is disposed. Each of vessel has a sidewall from which a flange projects. The flange of the outer vessel includes an annular wall. The flange of the inner vessel includes an engagement surface having an annular groove to receive the annular wall of the outer vessel. The inner vessel is arranged to be supported within the outer vessel on the flange of the outer vessel and with portions of the annular wall and annular groove engaging each other. Ultrasonic energy is applied to one of the flanges adjacent the engaging surfaces to concentrate the ultrasonic welding energy at those surfaces to produce a good double sided shear joint weldment thereat.
