<P>PROBLEM TO BE SOLVED: To improve appearance of such members made of plastics as a cap, an operational button and a cover body to be used for a pump type container and an aerosol type container, and to facilitate correspondence to changing specifications. <P>SOLUTION: A covering body 6 as an appearance member with a thin and uniform thickness is suitable for a screw cap body 5 as a functional central member to make a sink mark and a gate mark generated on the screw cap body 5 invisible. As no sink mark is generated on the covering body 6, disturbance of reflective action is invisible when a mirror face plating treatment and a lustrous coating treatment are applied on the surface. In addition, as the screw cap body 5 and the covering body 6 are separately produced and are assembled together, it becomes easy to change specification only on function or on appearance to minimize waste. <P>COPYRIGHT: (C)2010,JPO&INPIT |
