A double-walled insulated cup of paper material having an outer sleeve and an inner cup with a truncated conical wall and a bottom wall interconnected by a peripheral edge frame. The inner cup has a top shoulder and a bottom shoulder and the outside diameter of the inner cup at the level of the top shoulder increases toward the top edge of the inner cup. The outer sleeve lies against the inner cup in the region of the top shoulder thereof and extends to the bottom edge of the peripheral edge frame. The outside diameter of the outer sleeve at the level of the bottom edge of the peripheral edge frame is smaller than the inside diameter of the inner cup just above the bottom shoulder and is greater than the inside diameter of the inner cup just below the bottom shoulder.

1. A double-walled insulated cup of paper material, comprising an inner cup having a generally truncated conical wall and a pot-type bottom wall, said conical wall and said bottom wall being interconnected by a peripheral edge frame, and further comprising an outer sleeve, wherein said inner cup has a top shoulder in a top half of said inner cup and a bottom shoulder in a bottom half of said inner cup, wherein an outside diameter of said inner cup at a level of said top shoulder increases toward a top edge of said inner cup as regarded from said bottom wall of said inner cup, wherein said outer sleeve rests against said inner cup at least in a region of said top shoulder thereof, wherein said outer sleeve extends at least down to a bottom edge of said peripheral edge frame and lies against the peripheral edge frame at least in a region of the bottom edge of said peripheral edge frame, and wherein an outside diameter of said outer sleeve at a level of the bottom edge of said peripheral edge frame is smaller than an inside diameter of said inner cup just above said bottom shoulder and is greater than an inside diameter of said inner cup just below said bottom shoulder, and wherein the peripheral edge frame continuously widens in a direction away from the bottom wall down to the bottom edge of the peripheral edge frame. 2. The double-walled insulated cup as defined in claim 1, wherein said outer sleeve is wrapped around the bottom edge of said peripheral edge frame. 3. The double-walled insulated cup as defined in claim 2, wherein said outer sleeve is attached to an internal surface of said peripheral edge frame. 4. The double-walled insulated cup as defined in claim 1, wherein said outer sleeve is attached to said inner cup in the region said top shoulder. 5. The double-walled insulated cup as defined in claim 1, wherein said outer sleeve has a truncated cone shape and extends from an underside of a mouth bead Idisposed on said inner cup down to the bottom edge of said peripheral edge frame. 6. The double-walled insulated cup as defined in claim 1, wherein said outer sleeve lies flat against said peripheral edge frame at least partially in a contact region, which contact region extends upwardly from the bottom edge of said peripheral edge frame. 7. The double-walled insulated cup as defined in claim 6, wherein the outside diameter of said outer sleeve in a retracted region located above said contact region decreases more sharply than a taper of said outer sleeve above said retracted region. 8. The double-walled insulated cup as defined in claim 1, wherein said outer sleeve lies substantially flat against said inner cup in a region extending from said top shoulder of said inner cup up to an underside of a mouth bead disposed at a top end of said inner cup. 9. The double-walled insulated cup as defined in claim 1, wherein an angle of inclination of the peripheral edge frame is constant from the bottom wall to the bottom edge of the peripheral edge frame. 10. The double-walled insulated cup as defined in claim 9, wherein the outer sleeve is folded around the bottom edge of the peripheral edge frame. 11. A method for fabrication of a double-walled insulated cup of paper material comprising: fabricating an inner cup having a generally truncated conical wall and a pot-type bottom wall, attaching the generally truncated conical wall and the bottom wall to each other by of a peripheral edge frame, fabricating a generally truncated conical outer sleeve by joining longitudinal edges of a blank for said outer sleeve, sliding said outer sleeve onto said inner cup in a direction extending from said bottom wall of said inner cup to a wide end of said inner cup, and attaching a narrow end of said outer sleeve to the peripheral edge frame of said inner cup, wherein the peripheral edge frame continuously widens in a direction away from the bottom wall down to a bottom edge of the peripheral edge frame. 12. The method as defined in claim 11, wherein the narrow end of said outer sleeve is attached to said peripheral edge frame by wrapping the narrow end around the bottom edge of said peripheral edge frame. 13. The method as defined in claim 12, wherein following of wrapping said narrow end of said outer sleeve, attaching said outer sleeve at least partially to an external surface and/or to an internal surface of said peripheral edge frame. 14. The method as defined in claim 11, wherein said outer sleeve is slid onto said inner cup until a bottom edge of said outer sleeve is at a level of the bottom edge of said peripheral edge frame and wherein the narrow end of said outer sleeve is attached to said peripheral edge frame by joining an internal surface at the bottom edge of said outer sleeve to an external surface of said peripheral edge frame. 15. The method as defined in claim 11, wherein an angle of inclination of the peripheral edge frame is constant from the bottom wall to the bottom edge of the peripheral edge frame. 16. The method as defined in claim 11, further including folding the outer sleeve around the bottom edge of the peripheral edge frame. 17. A double-walled insulated cup of paper material, comprising an inner cup having a generally truncated conical wall and a pot-type bottom wall, said conical wall and said bottom wall being interconnected by a peripheral edge frame, and further comprising an outer sleeve, wherein said inner cup has a top shoulder in a top half of said inner cup and a bottom shoulder in a bottom half of said inner cup, wherein an outside diameter of said inner cup at a level of said top shoulder increases toward a top edge of said inner cup as regarded from said bottom wall of said inner cup, wherein said outer sleeve rests against said inner cup at least in a region of said top shoulder thereof, wherein said outer sleeve extends at least down to a bottom edge of said peripheral edge frame and lies against the peripheral edge frame at least in a region of the bottom edge of said peripheral edge frame, and wherein an outside diameter of said outer sleeve at a level of the bottom edge of said peripheral edge frame is smaller than an inside diameter of said inner cup just above said bottom shoulder and is greater than an inside diameter of said inner cup just below said bottom shoulder, and wherein the peripheral edge frame continuously widens in a direction away from the bottom wall down to the bottom edge of the peripheral edge frame, wherein an angle of inclination of the peripheral edge frame is constant from the bottom wall to the bottom edge of the peripheral edge frame. 18. The double-walled insulated cup as defined in claim 17, wherein the outer sleeve is folded around the bottom edge of the peripheral edge frame. 19. A double-walled insulated cup of paper material, comprising an inner cup having a generally truncated conical wall and a pot-type bottom wall, said conical wall and said bottom wall being interconnected by a peripheral edge frame, and further comprising an outer sleeve, wherein said inner cup has a top shoulder in a top half of said inner cup and a bottom shoulder in a bottom half of said inner cup, wherein an outside diameter of said inner cup at a level of said top shoulder increases toward a top edge of said inner cup as regarded from said bottom wall of said inner cup, wherein said outer sleeve rests against said inner cup at least in a region of said top shoulder thereof, wherein said outer sleeve extends at least down to a bottom edge of said peripheral edge frame and lies against the peripheral edge frame at least in a region of the bottom edge of said peripheral edge frame, and wherein an outside diameter of said outer sleeve at a level of the bottom edge of said peripheral edge frame is smaller than an inside diameter of said inner cup just above said bottom shoulder and is greater than an inside diameter of said inner cup just below said bottom shoulder, and wherein the peripheral edge frame continuously widens in a direction away from the bottom wall down to the bottom edge of the peripheral edge frame, wherein the outer sleeve is folded around the bottom edge of the peripheral edge frame.
