<P>PROBLEM TO BE SOLVED: To provide a synthetic resin molded article that ensures its resistance against contents and strength, while maintaining its moldability, even when it is used for a constituting part of a trigger dispenser or a container cap which may contact with liquid contents containing at least hypochlorite or hydrogen peroxide. <P>SOLUTION: The synthetic resin molded article which is mounted on a container holding liquid contents containing hypochlorite or hydrogen peroxide and may contact with the liquid content is molded using either of the resin compositions comprising a high density polyethylene obtained from homo-polymerization of ethylene or an ethylene copolymer with a density of 0.91-0.97 g/cm<SP>3</SP>obtained from copolymerization of ethylene and a 3-20C α-olefin. The synthetic resin molded article ensures resistance against the contents (chemical resistance) and the strength, even when it contacts with liquid contents containing hypochlorite or hydrogen peroxide as in the case of the constituting parts 101-116 of the trigger dispenser 100 and maintains moldability such as molding accuracy in injection molding. <P>COPYRIGHT: (C)2004,JPO |
