Patent number: 10562674Abstract: A plastic formed body having a pouring port 110 for pouring out highly wetting liquid that wets plastics to a high degree, wherein at least either a surface 110b that becomes a liquid-drip flow passage when said liquid drips at the pouring port 110 or a surface 110a that becomes a flow passage when said liquid is poured out, is coated with a fluorine-contained resin, and a surface of the fluorine-contained resin coating has an arithmetic mean roughness (Ra) in a range of 0.4 to 200 ?m in the surface roughness measurement and an element mean height (Rh) in a range of 0.04 to 10 as defined by mean height (Rc)/element mean length (RSm) in the linear roughness measurement. The formed body effectively prevents said highly wetting liquid from dripping at the pouring port 110.Type: GrantFiled: January 13, 2015Date of Patent: February 18, 2020Assignee: TOYO SEIKAN CO., LTD.Inventors: Kouki Kinouchi, Teijirou Kanada, Kenji Yoshihiro
