摘要:
A problem to be solved by this invention is to control the above-described problem of delamination in the laminated and biaxially drawn, blow molded bottle. A major means of this invention to solve this problem is a biaxially drawn, blow molded bottle characterized in that vertical connecting zones having no intermediate layer and having substrate layers welded directly with each other are formed in parallel in a circumferential direction and in a plural number along an axial direction of the bottle and are disposed on both right and left sides of each intermediate layer segment to be formed in this height range, and that horizontal connecting zones having no intermediate layer and having substrate layers welded directly with each other are also formed in parallel in an axial direction and in a plural number along a circumferential direction of the bottle and are disposed on both upper and lower sides of each intermediate layer segment to be formed, thus allowing the intermediate layer to be segmentalized in the circumferential and axial directions by both the vertical and horizontal connecting zones.
