PROBLEM TO BE SOLVED: To provide a cap and spout that can be manufactured by an existing forming device and has superior barrier properties, and to provide a method of manufacturing the same.SOLUTION: A container cap or spout comprises a molded body molded by using a resin composition containing 3-30 pts.mass of polyamide (C)containing, 60-97 pts.mass of unmodified polyolefin (A), 0-20 pts.mass of acid modified polyolefin (B), diamine unit derived from metaxylylenediamine, and dicarboxylic acid unit derived from 4-20 carbon atoms of α,ω-linear aliphatic dicarboxylic acid. The container cap or spout has a part with the polyamide (C) dispersed in layers in the molded body, and in which a length of the polyamide (C) dispersed in layers is 500 μm or more. Also, the method of manufacturing the container cap or the spout is provided by using an injection molding method or a compression molding method. |
