<P>PROBLEM TO BE SOLVED: To provide molded articles such as lidded medical equipment container, lidded disposable physics/chemistry testing instrument, lidded and hollowed sterilized slide glass, monolithic molded eyeglasses, windowpane with unevenness, character or pattern, frame or locking device, illuminator cover, tableware, roof tile and helmet which are made of a PET resin showing outstanding pliability, transparency, radiation resistance, impact resistance and the like. <P>SOLUTION: The PET resin molding workpiece is obtained by the monolithic molding of a plurality of components such as main body and lid through a hinge which forms the thinnest part of not less than 0.2 mm, using the PET resin which enables injection molding to be performed by increasing fluidity through copolymerization and compounding technique. The monolithic molded articles are cited as the medical equipment container including a sterile medical equipment container, instruments used for physics/chemistry test, slide glass, monolithic eyeglasses of lens and frame, windowpane, illuminator cover, tableware, roof tile, helmet and the like. In addition, the molding conditions of an injection molding machine are that a cylinder temperature be 240 to 285°C and the injection velocity be changed from low to medium. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
