<p>PROBLEM TO BE SOLVED: To improve the hardness of the external surface of a container, suppress the coefficient of dynamic friction to a low value, and also, improve the scratch-resistance of the container, and the adhesion property between a coating and a cyclic olefin based copolymer by covering the external surface of the cyclic olefin based copolymer with a cation setting type ultraviolet-curing film. SOLUTION: This container is formed by a draw-blow-forming of a cyclic olefin based copolymer, and on the external surface of a container wall 6, a cation setting type ultraviolet setting film 7 is formed. As the cyclic olefin based copolymer, a non-crystalline or low crystalline copolymer of olefin, is used. The cation setting type coating comprises a composition containing a cation type ultraviolet ray polymerization initiator and an alicyclic epoxy resin. For the cation type ultraviolet polymerization initiator, an aromatic iodonium salt, etc., can be mentioned. As the alicyclic epoxy resin, an epoxy compound having an epoxy cyclohexane ring, etc., are used singly or by being combined.</p> |
