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.

1. An insulated drinking vessel comprising a generally cylindrical outer vessel and a generally cylindrical inner vessel, each of said vessels being blow molded of a plastic material, said outer vessel having a sidewall from which a first flange projects outward, said first flange having an undersurface adapted for engagement by a separate support structure, said inner vessel having a sidewall from which a second flange projects, said first flange including an annular wall upstanding therefrom, said annular wall having a predetermined height and being formed by a pair of sidewall surfaces tapering toward each other at a slight angle, said annular wall terminating in a top surface, said second flange including an engagement surface having an annular groove to receive said annular wall to form a permanent welded joint, a first part or top of said annular groove being formed by a pair of sidewalls which are parallel to each other and separated from each other by a distance slightly less than the distance separating said sidewall surfaces of said annular wall at said top surface of said annular wall, a second part of said annular groove having a chamfered entryway contiguous with said engagement surface, said inner vessel being disposed within said outer vessel, with said first and second flanges juxtaposed to each other so that said inner vessel is supported by said first flange of said outer-vessel, with a portion of said annular wall contiguous with said end surface of said annular wall being received within said chamfered entryway, said undersurface of said first flange of said outer vessel being adapted to be engaged and suspended by a support structure so that said inner vessel and said outer vessel can be ultrasonically welded together while so suspended, and wherein said second flange has a surface that is adapted to be engaged with an ultrasonic welding device, whereupon ultrasonic energy can be applied thereto and concentrated thereat to ultrasonically weld said inner vessel and said outer vessel together so that said annular wall extends through said chamfered entryway and fully enters said first part of said annular groove to thereby create said permanent welded joint, said permanent welded joint being a double sided shear joint. 2. The assembly of claim 1 wherein said insulated drinking vessel includes an insulating space located between said outer vessel and said inner vessel. 3. The assembly of claim 1 wherein said annular wall projects upward from said flange of said outer vessel and wherein said annular groove is located in said flange of said inner vessel. 4. The assembly of claim 2 wherein said inner vessel includes a threaded top portion arranged to receive a threaded lid assembly thereon. 5. The assembly of claim 4 wherein said lid assembly includes a cap portion which is arranged to be pivoted between an open and a closed position, said cap portion being arranged to close off said hollow inner vessel when said lid is in said closed position. 6. A method of ultrasonically welding a blow molded product, said method comprising: providing an outer hollow member that is blow molded of a plastic material and an inner hollow member that is blow molded of a plastic material, said outer member having a sidewall from which a flange projects, said inner member having a sidewall from which a flange projects, a first one of said flanges including an annular wall upstanding therefrom, said annular wall having a pair of sidewall surfaces tapering toward each other at a slight angle and terminating in an end surface of, said other of said flanges including an engagement surface having an annular groove to receive said annular wall, a first part of said annular groove having sidewalls which are separated from each other by a distance slightly less than the distance separating said sidewall surfaces of said annular wall at said top surface of said annular wall, a second part of said annular groove having a chamfered entryway contiguous with said engagement surface;disposing said inner member within said outer member with said flanges of said members juxtaposed to each other wherein said end surface of said annular wall engages said chamfered entryway of said first part of said annular groove to form engaging surfaces; andbringing an ultrasonic welding device into engagement with a surface of one of said flanges adjacent said engaging surfaces and operating said device to apply ultrasonic welding energy thereto and concentrating said ultrasonic energy thereat to enable said annular wall to enter said annular groove and thereby create a good double sided shear joint weldment thereat. 7. The method of claim 6 wherein said outer member with said inner member located therein is suspended from a support structure by said flange of said outer member when said ultrasonic welding device is brought into engagement with a surface of one of said flanges to produce said weldment. 8. The method of claim 7 wherein the ultrasonic welding device is brought into engagement with said flange of said inner member. 9. The method of claim 8 wherein said annular wall projects upward from said flange of said outer member and wherein said annular groove is located in said flange of said inner member. 10. The method of claim 6 wherein said product is an insulated vessel assembly and wherein said outer member comprises a hollow vessel, wherein said inner member comprises a hollow vessel and wherein said insulated vessel assembly includes an insulating space located between said outer member and said inner member.
