PROBLEM TO BE SOLVED: To solve such a problem that the temperature of a heated and softened thermoplastic sheet is lowered during transfer when the thermoplastic sheet is extremely thin and a molded porous container can not be covered with the thermoplastic sheet. SOLUTION: A thermoplastic sheet covering apparatus, which arranges the heated and softened thermoplastic sheet S1 to the opening part V11 of the molded porous container V1 housed in a predetermined thermoforming female mold 26 to laminate and bond the same to the inside surface of the porous container V1 by thermoforming, is provided with a first heater 22 (temperature lowering preventing mechanism) for preventing the lowering of the temperature of the thermoplastic sheet S1 arranged to the acrylic resin plate or molded article 2 thereof. Since the first heater 22 prevents the lowering of the temperature of the thermoplastic sheet S1, the thermoplastic sheet S1 is brought into close contact with the inside surface V14 of the molded porous container V1 by thermoforming to be laminated and bonded to the porous container V1. |
