<p>A plastic container produced by melt blow-molding a parison extruded from an extruder, wherein the wall-thickness of predetermined portion of the mouth (3) and/or barrel (2) is greater than that of the barrel main body, and one or more lines of thickened portion of the barrel (2) are continuously or discontinuously formed circumferentially, vertically or spirally of the container barrel in whole or in part. This improves the rigidity, appearance and functions of the container even if the barrel is made thin-walled.</p> |
