<p>PURPOSE:To obtain a vessel made of plastic which may prevent the viscous and fluid product, etc., received inside from being deteriorated by a method in which the formed body in shoulder part is composed of the multilayer plastic sheet containing a gas-barrier resin layer. CONSTITUTION:The vessel 10 made of plastic is composed of a cylindrical barrel part 11 and the shoulder part 12 provided on the upper end of the barrel part 11. The shoulder part 12 is composed of the formed object 15 of the shoulder part made of multilayer plastic sheet and the synthetic resin 16 compression- formed or injection-molded on the surface of the formed object 15 of the shoulder part. Since thus, for instance the formed object 15 of the shoulder part is composed of the multilayer plastic sheet containing the copolymer (EVOH) of ethylene vinyl alcohol with gas-barrier property, the gas-barrier property of the shoulder part 12 may be surely held. Even when the upper end of a cylindrical body 15b is exposed in the vessel 10 made of plastic, viscous and fluid product is not deteriorated as in conventional one by the corrosion of Al.</p> |
