PROBLEM TO BE SOLVED: To provide a blow-molded vessel and an infusion plastic vessel using the same, which prevent the occurrence of a residual liquid in the discharge of a liquid, and eliminate a fear that a pinhole may appear in a deposited part between a flange and a stopper body. SOLUTION: In the blow-molded vessel 1, an opening 11 is formed in a flange shape, and a plurality of ribs 14, which are extended in an axial direction from an opening end 11, are provided in inner walls of the opening 11 and a neck part 12. Though the ribs 14 can be provided throughout the neck part 12 in the axial direction, it is proper to form the ribs 14 so that the shoulder-part side of the neck part 12 can remain by a small area so as to prevent drag-in a resin from reaching a shoulder part 13. |
