An insulated drinking vessel, e.g., a wine glass, and a method of making the same is disclosed. The drinking vessel basically comprises an outer vessel, an inner vessel and a ring. The inner and outer vessels each include a sidewall. The sidewalls are spaced apart. At least one of the outer vessel, the inner vessel and the ring are pre-molded to form an integral structure having a vestige of a molding gate used to mold the integral structure. At least one of the inner and outer vessels and the ring is molded in situ on the integral structure to cause portions thereof to melt and intermingle to form a non-superficial homogenous joint, with the ring forming the rim or lip of the insulated drinking vessel.

The insulated drinking vessel of claim 1 wherein said outer vessel has a top edge portion, said ring comprises said second separate pre-molded component having a bottom edge portion which may include the vestige of a molding gate used to form said ring, and wherein said inner vessel comprises said final stage component that is molded in-situ on said bottom edge portion of said pre-molded ring which causes the plastic material thereof to fuse together and intermingle with said plastic material of said ring to form a non-superficial homogenous joint eliminating the visible appearance of said vestige, said top edge portion of said outer vessel being fixedly secured to said bottom edge portion of said ring at a weld joint, said ring forming the lip of said drinking vessel. 3. The insulated drinking vessel of claim 2 wherein said plastic material of said inner vessel, said outer vessel and said ring is the same plastic material. 4. The insulated drinking vessel of claim 2 wherein said plastic material comprises copolyester. 5. The insulated drinking vessel of claim 2 wherein said weld joint comprises an annular projection located within an annular recess. 6. The insulated drinking vessel of claim 2 wherein said inner vessel, said outer vessel and said ring are transparent. 7. The insulated drinking vessel of claim 2 wherein said inner vessel and said outer vessel are transparent and wherein said ring is colored. 8. The insulated drinking vessel of claim 2 wherein said inner vessel includes a sidewall and wherein said outer vessel comprises a sidewall, and wherein portions of said sidewall of said inner vessel are spaced from portions of said sidewall of said outer vessel to form an insulating air space therebetween. 9. The insulating drinking vessel of claim 2 wherein said weld joint comprises a far-field ultrasonically welded joint. 10. The insulating drinking vessel of claim 6 wherein said weld joint comprises a far-field ultrasonically welded joint. 11. The insulated drinking vessel of claim 1 wherein said outer vessel has a top portion, said inner vessel comprises said second separate pre-molded component and wherein inner vessel and said outer vessel are joined together by a weld joint at said top portions thereof to form a pre-molded unitary structure having a top edge portion which may include a vestige of a molding gate used to mold at least one of said inner and outer vessels, said ring comprising said final stage component and comprising a plastic material molded in-situ on said top edge portion of said pre-molded unitary structure to cause said plastic material of said ring to fuse together and intermingle with said plastic material of said pre-molded unitary structure to form a non-superficial homogenous joint eliminating the visible appearance of said vestige, said ring forming the lip of said drinking vessel. 12. The insulated drinking vessel of claim 11 wherein said plastic material of said inner vessel, said outer vessel and said ring is the same plastic material. 13. The insulated drinking vessel of claim 12 wherein said plastic material comprises copolyester. 14. The insulated drinking vessel of claim 11 wherein said weld joint comprises an annular projection located within an annular recess. 15. The insulated drinking vessel of claim 11 wherein said inner vessel, said outer vessel and said ring are transparent. 16. The insulated drinking vessel of claim 11 wherein said inner vessel and said outer vessel are transparent and wherein said ring is colored. 17. The insulated drinking vessel of claim 11 wherein said inner vessel includes a sidewall and wherein said outer vessel comprises a sidewall, and wherein portions of said sidewall of said inner vessel are spaced from portions of said sidewall of said outer vessel to form an insulating air space therebetween. 18. The insulating drinking vessel of claim 11 wherein said weld joint comprises a far-field ultrasonically welded joint. 19. The insulating drinking vessel of claim 15 wherein said weld joint comprises a far-field ultrasonically welded joint. 20. A method for making an insulated drinking vessel comprising: a) providing an outer vessel pre-molded of a plastic material and having a top edge portion;b) providing a ring pre-molded of a plastic material and having a bottom edge portion;c) molding an inner vessel of a plastic material in-situ on said bottom edge portion of said ring to cause the plastic material thereof to fuse together and intermingle with said plastic material of said ring to form a non-superficial homogenous joint at a bottom edge portion of said ring; andd) fixedly securing said top edge portion of said outer vessel to a bottom edge portion of said ring by a weld joint. 21.
