Disclosed is a vessel closure provided with an easily openable liner, said liner being composed of an olefin resin or olefin resin composition comprising as a lubricant a combination of (A) at least one member selected from the group consisting of compounds represented by the following formula:n wherein R stands for a saturated or unsaturated aliphatic hydrocarbon group, and X stands for a carboxyl group, a hydroxyl group, an amide group, an amino group or a hydrogen atom, and (B) at least one member selected from the group consisting of compounds represented by the following formula:n wherein R is defined above and Y stands for a carboxyl group, a hydroxyl group, an amide group, an amino group or a hydrogen atom, with the proviso that Y is different from X in the formula (1). n In this vessel closure, the quantity of the lubricant immigrating to the surface of the liner is effectively controlled within a certain range at temperatures of a broad range and the opening torque is controlled at a low level at storage temperatures of a broad range. |
