Blow molded bottle body made of a polyolefin resin

摘要

PROBLEM TO BE SOLVED: To create a side peripheral wall shape on the decompression absorption function suitable for a bottle body made of polyolefin resin by direct blow molding.;SOLUTION: In the blow molding bottle body 1 made of the polyolefin resin, a side peripheral wall of a body part 4 is constituted of a curved-shaped part for forming a part over a side surface from the front surface side in a curved shape along the peripheral direction, a flat part for forming the back face side in a flat shape and a corner part for connecting the curved-shaped part and the flat part, a groove rib is annularly formed inside the outer peripheral edge of the flat part by bending the side peripheral wall along this outer peripheral edge, and an average value of a wall thickness of end part areas reaching the corner part from a bottom part of a pair of groove ribs positioned on the left and right of the flat part is thinned in a thickness by comparing with an average value of a wall thickness of a central area positioned between the pair of groove ribs.;COPYRIGHT: (C)2014,JPO&INPIT
