の真空成形法の成形工程によりシート７を加熱軟化させ
、柔軟な状態で成形が開始される。Next, the procedure for fixing a pipe for preventing condensation in a refrigerator according to the present invention will be explained.The inner box 3 is formed by vacuum forming. That is, as shown in FIG. 2, the pipe 5 is removably disposed in an arcuate groove 6c that is continuously formed in the flange molded part 6a around the vacuum mold 6 and the partition molded part 6b in the center. Next, a synthetic resin sheet 7 is temporarily placed above the vacuum forming mold 6 in step 1 with a gap left therebetween. Then, the sheet 7 is heated and softened by a forming process of a well-known vacuum forming method, and forming is started in a flexible state.
