<p><P>PROBLEM TO BE SOLVED: To form a mouth cylinder portion, which can be easily plucked off in a refilling container relatively thinly shaped by blow molding, in a blow molding process for the container simultaneously so as to provide the refilling container used conveniently at a low cost. <P>SOLUTION: The blow molded container has the mouth cylinder portion erected on the upper part of the trunk of the container. A melt fracture is produced at a part at a given level on the mouth cylinder portion by parison extrusion molding to form a weakened part at the given level on the mouth cylinder portion so that the cylinder portion can be plucked off. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
