<p>PURPOSE:To manufacture a blow molded outer layer bottle of heat resistance and also of superior light shielding properties and barrier properties. CONSTITUTION:A bottle is provided with a cap 1, a support ring 5 provided at the lower end the cap, a shoulder section 2 formed successively to the support ring, a body 3 and a bottom 4, and the cap 1 is formed by a light shielding resin layer 7 and a heat-resistant resin layer 9, while the body is formed by the light shielding layer 7 and a barrier resin layer 8. The light shielding resin layer 7 is composed of resin containing 2.5-6.0 pts.wt. of a light reflective pigment and 0.005-0.015 pts.wt. of a light absorbing pigment to 100 pts.wt. of polyester.</p> |
