<p><P>PROBLEM TO BE SOLVED: To provide a bottle-type plastic blow-molded infusion vessel, erected upright and hardly generating dead space on a shoulder part or a bottom part when a liquid is discharged (and therefore, requiring less air injection for clearing the remaining liquid off the vessel). <P>SOLUTION: The blow-molded vessel has a mouth part 1, a neck part 2, the shoulder part 3, a barrel part 4 and the bottom part 5. The barrel part 4 has a pair of wide side faces 41 and a pair of narrow side faces 42. The bottom part 5 is symmetrical relative to the longitudinal axis of the bottom part 5 and is bent inward in the V-shape. The shoulder part 3 has a pair of wide side faces 31 and a pair of narrow side faces 32, and each narrow side face 32 has a groove part 33 symmetrical relative to the longitudinal axis and bent inward in the V-shape. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
