PURPOSE:To provide a lined container cap which has excellent sealing performance, openability, hygienic characteristics, etc., by applying a specified vinyl chloride resin compsn. contg. a mixed fatty acid glyceride blended threrewith on the inner surface of a container cap. CONSTITUTION:35-200pts.wt. mixed fatty acid glyceride of the formula[wherein one or two of R<1>, R<2>, R<3> is/are a 6-24c (an even number) residue of a higher fatty acid, a residue of acetic or butyric acid (one of R<1>, R<2>, R<3> may be a hydrogen atom)]such as diacetylmonolauryl glyceride is blended with 100pts.wt. vinyl chloride resin to obtain a resin compsn. which is then applied to the inner surface of a container cap to form a liner of 0.3-4mm. in thickness. Pref. the compsn. is used in the form of a plastisol whose viscosity is adjusted by adding an epoxy or a polyester plasticizer. |
