<p><P>PROBLEM TO BE SOLVED: To create a peripheral wall structure allowing smooth pour-out operation regardless of residual quantity of contained liquid and allowing to use the contained liquid generally to the last in a delamination bottle type blow-molded bottle. <P>SOLUTION: A bent peripheral wall part is arranged circumferentially at a middle height position of a body in a recessed shape to be invertedly deformed in a manner buckled in the vertical direction over the entire periphery by bending a peripheral wall of the body, the body is vertically separated into two of an upper body and a lower body by the bent peripheral wall part, an outer layer embraces an inner layer after inverted deformation at a mountain fold bent part formed by the peripheral wall positioned within a range from the lower end of the peripheral wall of the upper body to the upper end of the peripheral wall of the lower body, the inner layer is circumferentially fixed by the embrace, and an inlet port introducing the external air between the outer layer and the inner layer is arranged in an outer layer part positioned in a region from the lower body to the bottom. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
