An insulated drinking vessel, e.g., a wine glass, and methods of making the same is disclosed. The vessel basically comprises a pre-molded inner vessel formed of a plastic material having a sidewall, a pre-molded outer vessel formed of a plastic material, and a ring. The ring is formed of a plastic material and is molded in-situ on a top portion of the inner vessel to cause portions of the plastic material of the inner vessel to melt and intermingle with the plastic material of the ring to form a non-superficial homogenous joint therebetween. The inner vessel is disposed within the outer vessel and the ring is welded to a top portion of the outer vessel. The ring forms the rim or lip of the insulated drinking vessel and that vessel includes an insulating air space between the sidewall portions of the inner and outer vessels.

Insulated double walled drinking vessel and method of making the same

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.

Insulated wine glass

An insulated drinking vessel, e.g., a wine glass, and a method of making the same is disclosed. The vessel basically comprises a pre-molded outer vessel formed of a plastic material having a sidewall, a pre-molded ring formed of a plastic material, and an inner vessel having a sidewall. The ring includes a bottom end at which the vestige of a molding gate may be located. The inner vessel is formed of a plastic material molded in-situ on the bottom end of the ring to cause portions of the ring's plastic to melt and intermingle with the plastic material of the inner vessel to form a subassembly including a non-superficial homogenous joint between the ring and the inner vessel. The sidewall of the inner vessel of the subassembly is disposed within the sidewall of the outer vessel and the ring is welded to a top portion of the outer vessel to form the rim or lip of the insulated drinking vessel.

The vessel basically comprises a pre-molded inner vessel formed of a plastic material having a sidewall is disposed within a pre-molded outer vessel formed of a plastic material having a sidewall to form a subassembly having an insulating air space between the sidewalls. Each of the vessels includes a contoured surface including at least one projection or depression. A ring of plastic material is molded in-situ on the contoured surfaces to cause portions thereof to melt and intermingle with the plastic material of the ring to form a homogenous joint having a depth no greater than approximately 0.003 inch. The ring forms the rim or lip of the insulated drinking vessel.
