A vessel composed of a sheet of flexible material, cut, rolled, and affixed to form a frusto-conically shaped base region. The sheet when rolled including an upper region having two opposing flaps, each flap delineated from a remaining portion of the sheet by a path along which the sheet is scored, so that the flaps, when folded along their respective paths, define a single elevated drinking portion having a spout formed between an extension of the base region and at least one of the two flaps.

1. A vessel comprising: a sheet of flexible material, cut, rolled, and affixed to form a frusto-conically shaped base region, the base region having a bottom edge,wherein the sheet, when thus rolled, also includes an upper region having two opposing flaps, each flap delineated from a remaining portion of the sheet by a path along which the sheet is scored, so that the flaps, when folded along their respective paths, define (i) a vent portion having a first height above the bottom edge of the base region and an aperture that vents air into the vessel, and (ii) a single elevated drinking portion having a drinking spout formed between an extension of the base region and at least one of the two flaps, wherein:the drinking spout includes a slot having an areal dimension that is substantially greater than an areal dimension of the aperture; andthe drinking portion has a second height, above the bottom edge of the base region, that is greater than the first height. 2. A vessel according to claim 1, wherein one of the two flaps is an outer flap and the other flap is an inner flap such that the outer flap overlies the inner flap when the two flaps are folded. 3. A vessel according to claim 2, wherein the outer flap has a first edge shaped to coincide, when the flaps are folded, approximately with the path of scoring in the inner flap. 4. A vessel according to claim 3, wherein the outer flap includes a closure tab formed as part of the sheet and protruding from the first edge, and scored along a first line wherein it protrudes from the first edge, to permit the closure tab to be folded along the first line so as to overlie a portion of the base region. 5. A vessel according to claim 4, wherein the closure tab is removably attachable to the portion of the base region. 6. A vessel according to claim 3, wherein the inner flap has a second edge shaped to coincide, when the flaps are folded, approximately with the path of scoring in the outer flap. 7. A vessel according to claim 6, wherein the inner flap includes an opening tab formed as part of the sheet and protruding from the second edge, and scored along a second line wherein it protrudes from the second edge, to permit the opening tab to be folded along the second line so as to protrude upwardly from a plane of a surface of inner flap, to facilitate unfolding of the inner flap after it has been folded. 8. A vessel according to claim 1, further comprising a bottom formed from a second sheet of material, affixed in an opening of the base region, so as to enable the vessel to retain a liquid placed therein via an opening in the upper region existing when the flaps are unfolded. 9. A vessel according to claim 8, wherein the bottom is generally circular. 10. A vessel according to claim 8, wherein the second sheet of material is part of the first sheet of material. 11. A vessel according to claim 9, wherein the bottom has been folded to a circular flat-bottomed surface having a circumferential wall, the circumferential wall being adhered to an interior portion of the base region. 12. A method of making a vessel comprising: cutting a sheet of flexible material, scoring, rolling and gluing it so as to assume the shape of a vessel according to claim 1. 13. A vessel comprising: a sheet of flexible material, cut, rolled, and affixed to form a frusto-conically shaped base region,wherein the sheet, when thus rolled, also includes an upper region having an outer flap and an opposing inner flap, each flap delineated from a remaining portion of the sheet by a path along which the sheet is scored so that the outer flap overlies the inner flap, when folded along their respective paths, such that the outer flap and the inner flap define a single elevated drinking portion having a spout formed between an extension of the base region and at least one of the two flaps, and wherein the outer flap comprises: a first edge shaped to coincide, when the inner flap and outer flap are folded, approximately with the path of scoring in the inner flap; anda closure tab formed as part of the sheet and protruding from the first edge, and scored along a first line wherein it protrudes from the first edge, to permit the closure tab to be folded along the first line so as to overlie a portion of the base region, the tab further comprising an adhesive layer such that the tab is removably attachable to the portion of the base region. 14. A vessel according to claim 13, wherein: the base region has a bottom edge;the flaps, when folded along their respective paths, further define a vent portion having an aperture, for venting air into the vessel, the vent portion having a first height above the bottom edge of the base region, and whereinthe drinking spout includes a slot having an areal dimension that is substantially greater than an areal dimension of the aperture; andthe drinking portion has a second height, above the bottom edge of the base region, that is greater than the first height. 15. A vessel according to claim 13, wherein the inner flap includes an opening tab formed as part of the sheet and protruding from the second edge, and scored along a second line wherein it protrudes from the second edge, to permit the opening tab to be folded along the second line so as to protrude upwardly from a plane of a surface of inner flap, to facilitate unfolding of the inner flap after it has been folded. 16. A vessel comprising: a sheet of flexible material, cut, rolled, and affixed to form a frusto-conically shaped base region,wherein the sheet, when thus rolled, also includes an upper region having two opposing flaps, each flap delineated from a remaining portion of the sheet by a path along which the sheet is scored, so that the flaps, when folded along their respective paths, define a single elevated drinking portion having a spout formed between an extension of the base region and at least one of the two flaps; anda dam disposed on at least one of the opposing flaps to restrain contents of the vessel from flowing between the flaps and escaping from the vessel. 17. A vessel according to claim 16, wherein the dam includes at least one engaging pair of embossments in the material of the flaps. 18. A vessel according to claim 16, wherein the dam includes a bead of a second material.
