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.
