<p>PURPOSE:To manufacture a blow molded 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 disposed at the lower end of said cap, a shoulder section 2 formed successively to the support ring, a body 3 and a bottom 4, and the cap 1 is of multi-layer structure composed of a light shielding barrier resin layer 7 and a heat-resistant resin layer 9, while sections other than the cap are composed of the light shielding resin layers 7. The light shielding barrier resin layer is composed of resin containing 5.3-19.0 pts.wt. of barrier resin, 2.7-7.6 pts.wt. of a light reflective pigment and 0.0054-0.019 pts.wt. of a light absorbing pigment to 100 pts.wt. of polyester.</p> |
