I claim: 1. An insulated cup comprising a top portion and a base sleeve that forms a bottom of the cup; said top portion having a side wall, a top, a bottom, a top opening, a bottom opening and a cavity extending from said top opening to said bottom opening, said top portion including a paper or ca
I claim: 1. An insulated cup comprising a top portion and a base sleeve that forms a bottom of the cup; said top portion having a side wall, a top, a bottom, a top opening, a bottom opening and a cavity extending from said top opening to said bottom opening, said top portion including a paper or cardboard material, said side wall of said top portion having an outer surface; and, said base sleeve formed of a single piece of material that includes a paper or cardboard material that includes a corrugated paper material or corrugated cardboard material, said base sleeve including a base, a side wall extending upwardly from said base, an upper opening and a sleeve cavity extending from an upper surface of said base to said upper opening, said upper surface forming an inner surface of said cup and a bottom surface of said cup such that when liquid is contained in said cup the liquid directly contacts said upper surface of said base of said base sleeve, said inner surface of said sleeve cavity absent a seam, said base sleeve fitted onto said bottom of said top portion so that said sleeve cavity of said base sleeve at least partially telescopically receives said side wall of said top portion and covers and seals said bottom opening of said top portion, said side wall of said base sleeve forming a portion of an outer surface of said cup to enable a user to grasp said side wall of said base sleeve and thereby insulate the user from a temperature of the liquid in said cup, said inner surface of said base sleeve connected to said outer surface of said side wall of said top portion and forming a liquid proof seal between said inner surface of said base sleeve and said outer surface of said side wall of said top portion, said inner surface of said base sleeve at least partially connected to said outer surface of said side wall of said top portion by an adhesive or heat created seal, said liquid proof seal at least partially formed by said adhesive or said heat created seal. 2. The insulated cup as defined in claim 1, wherein said side wall of said base sleeve is formed of a different material from said side wall of said top portion. 3. The insulated cup as defined in claim 1, wherein said base sleeve is formed of the same material as said top portion. 4. The insulated cup as defined in claim 1, wherein said base sleeve includes a multilayer material, said multilayer material including said corrugated paper or said corrugated cardboard material. 5. The insulated cup as defined in claim 1, wherein said side wall of said base sleeve extends upwardly from said bottom of said top portion to at least about 5% of a longitudinal length of said side wall of said top portion. 6. The insulated cup as defined in claim 5, wherein said side wall of said base sleeve extends upwardly less than the complete longitudinal length of said side wall of said top portion. 7. The insulated cup as defined in claim 6, wherein said cup has a longitudinal length, said base sleeve has a longitudinal length that is about 10-60 percent of the longitudinal length of said cup. 8. The insulated cup as defined in claim 7, wherein said side wall of said base sleeve extends upwardly from said bottom of said top portion to at least about 25% of a longitudinal length of said side wall of said top portion. 9. The insulated cup as defined in claim 8, wherein said side wall of said base sleeve extends upwardly from said bottom of said top portion to at least about 50% of a longitudinal length of said side wall of said top portion. 10. The insulated cup as defined in claim 6, wherein said side wall of said base sleeve extends upwardly at least about 0.5 inches and up to about 5 inches up said side wall of said top portion. 11. The insulated cup as defined in claim 1, wherein said side wall of said top portion is telescopically received into at least about 90% of a longitudinal length of said sleeve cavity of said base sleeve. 12. The insulated cup as defined in claim 1, wherein a majority of said liquid proof seal is positioned above a bottom edge of said bottom of said top portion. 13. The insulated cup as defined in claim 12, wherein all of said liquid proof seal is positioned above said bottom edge of said bottom of said top portion so that liquid in said insulated cup does not contact said liquid proof seal at said bottom surface of said cup. 14. The insulated cup as defined in claim 1, wherein said side wall of said top portion having a circular cross-sectional shape that varies in cross-sectional area along a longitudinal length of said top portion, said sleeve cavity of said base sleeve having a circular cross-sectional shape that varies in cross-sectional area along a longitudinal length of said base sleeve, said sleeve cavity of said base sleeve having a similar cross-sectional shape to said cross-sectional shape of said side wall of said top portion. 15. The insulated cup as defined in claim 1, wherein said base of said base sleeve includes a recessed portion which forms a recess in said bottom of said cup. 16. The insulated cup as defined in claim 1, wherein said base sleeve includes a coating of a sealing material. 17. The insulated cup as defined in claim 1, wherein said insulated cup is a 8-16 ounce cup. 18. The insulated cup as defined in claim 1, wherein said insulated cup consists of only said top portion and said base sleeve. 19. An insulated cup comprising a top portion and a base sleeve that forms a bottom of the cup; said top portion having a side wall, a top, a bottom, a top opening, a bottom opening and a cavity extending from said top opening to said bottom opening, said top portion including a paper or cardboard material, said side wall of said top portion having an outer surface, said top of said top portion including a rolled rim; and, said base sleeve formed of a single piece of material that includes a paper or cardboard material that includes a corrugated paper material or corrugated cardboard material, said base sleeve including a base, a side wall extending upwardly from said base, an upper opening and a sleeve cavity extending from an upper surface of said base to said upper opening, said upper surface of said base sleeve forming an inner surface of said cup, said inner surface of said sleeve cavity absent a seam, said base sleeve fitted onto said bottom of said top portion so that said sleeve cavity of said base sleeve at least partially telescopically receives said side wall of said top portion and covers and seals said bottom opening of said top portion, said inner surface of said base sleeve connected to said outer surface of said side wall of said top portion and forming a liquid proof seal between said inner surface of said base sleeve and said outer surface of said side wall of said top portion, said inner surface of said base sleeve at least partially connected to said outer surface of said side wall of said top portion by an adhesive or heat created seal, said liquid proof seal at least partially formed by said adhesive or said heat created seal.
