<p>PURPOSE:To provide a multilayered plastic container having excellent surface glass and impact resistance, hardly generating a surface damage and excellent in moldability by forming the outer layer of the multilayered plastic container from an amorphous resin obtained by copolymerizing cyclic olefin and ethylene and forming the inner layer thereof from a polyolefin resin. CONSTITUTION:A container 1 consists of a body part 2, the bottom part continued to the lower end of the body part 2 and formed by pinching off a parison and the mouth neck part 5 continued to the upper end of the body part 2 through a shoulder part 4. The mouth part 6 engaged with a lid member in a hermetically sealed state and the lid attaching part 7 composed of a screw, a bead, a flange or a stepped shoulder formed to the lower part of the mouth part 6 are provided to the mouth neck part 5. By using an amorphous resin obtained by copolymerizing cyclic olefin and ethylene in an outer layer, extremely high surface gloss is provided and the surface of the container is hardly damaged in a content filling line or at the time of the feed of the container. By using a polylefin resin excellent in impact resistance and good in moldability in an inner layer, a defect such that the outer layer is low in impact resistance and inferior to moldability is compensated.</p> |
