Abstract:
1. A method for thermo-molding a footed and bottomed cylindrical container, comprising: heating a thermoplastic resin sheet, pressing the heated sheet by a plug of an upper mold while vacuum-sucking, to contact the sheet with mold surfaces of a female mold of a lower mold, so as to form a body wall and an outer wall of a foot of the container, and blowing compressed fluid through blow-in holes of a bottom bush of the lower mold into the female mold while vacuum-sucking, to contact the sheet on a top surface of the bottom bush with a bottom surface of the plug, so as to form a bottom wall and an inner wall of the foot, said inner wall being fusion-bonded with the outer wall.
