PURPOSE:To obtain a vessel cover with an excellent liner in capping, unsealing and reserving the contents by providing the liner formed of a composition wherein a specific plasticizer-insoluble organic macromolecular filler is blended with a plastisol. CONSTITUTION:A liner is made of plastisol containing vinyl chloride resin, plasticizer, lubricant, and stabilizer. To this plastisol, 2-6vol.% of plasticizer- insoluble organic macromolecular filler per vinyl chloride resin, particularly preferably 5-40vol.% is combined. By blending a filler to the plastisol, the volume of the lubricant of the liner surface is kept within a proper range for a long period. A vessel cover with the liner is composed of a vessel 1 with a coated metal cover 1 and the liner 2 provided inside the vessel. The vessel 1 comprises a top plate 3 and a skirt 4 hanging from the periphery where a recess 8 for fitting the liner is provided and the liner 2 formed from plastisol is arranged in the groove 8. |
