PURPOSE: To form a plastic vessel with a rigid and thin thickness and further sufficiently durable against winding and fastening with hot charge, by utilizing polyethylene resin with a specific bending modulus and an izod impact strength as a main rigid body in the vessel.
CONSTITUTION: A plastic vessel utilized as a chief rigid member of polypropylene resin with a bending modulus of more than 11500kg/cm2 and an izod impact strength of more than 10kg.cm/cm, in a plastic vessel wound up and fastened with a winding up metal lid is formed. By such characteristics provided for the vessel, the backling strength of 30kg or more generally necessary for the winding and fastening with hot charge can be obtained by making use of a thin sheet with a thickness not more than 2.0mm.
