<p><P>PROBLEM TO BE SOLVED: To provide an in-mold vessel capable of raising temperature at which a flange is deformed by heat and improving working efficiency in a heating work. <P>SOLUTION: In a pudding vessel 11, a label 13 is integrally and tightly fitted and formed to an outer circumferential surface of a bottomed cylindrical vessel body 12 having an opening which is formed of a heat-resistant polypropylene resin by an in-mold forming method. The label 13 is integrally and tightly fitted substantially over the entire outer circumferential surface of a circumferential wall 12b, and further over the entire back side (lower side) of a flange 12c. The label 13 has a property that it is softened when exposed to the atmosphere exceeding 240°C. Thus, owing to the label 13, the temperature at which the flange 12c is deformed by heat is higher than the heat-resistant temperature of 130°C of the heat-resistant polypropylene resin. <P>COPYRIGHT: (C)2003,JPO</p> |
