PURPOSE: To provide a magic vessel applicable to toys by forming the vessel by a thermally discoloring resin material, so that a condition such that a liquid having a specified color is poured is imitatively sensed by the eyes, when a liquid having a temperature lower than a specified temperature is poured into the vessel. ;CONSTITUTION: In a magic vessel 5, the whole body including the side part circumferential wall 6 and bottom part 6 of the vessel is formed by use of a thermally discoloring resin. Transparency is imparted to the whole vessel. Further, the color similar to the color naturally possessed by a specified liquid is set in such a manner as to be capable of being reversibly shield by a temperature change. A liquid having a temperature lower than a specified temperature is poured into the vessel, whereby a condition such that a liquid having the specified color is poured is imitatively sensed by the eyes. Namely, the thermally discoloring resin material mainly consisting of a transparent thermoplastic material containing 0.2-5wt% of a thermally discoloring material and 3-50wt.% of a higher fatty acid ester or its metal salt is used. and it is molded at a temperature not exceeding 180°C.;COPYRIGHT: (C)1995,JPO
