<p>PROBLEM TO BE SOLVED: To provide a laminate separation synthetic resin blow molded container with high production efficiency, and excellent strength and economy which can firmly bond an inner layer to an outer layer at a bottom seal part without increasing any volume. SOLUTION: This blow molded container comprises the synthetic resin outer layer which forms an outer shell of the predetermined shape by the blow molding, the flexible synthetic resin inner layer which is separately laminated on the outer layer to form an inner bag, and a pair of two long strip-like adhesive bands 4 which adhere and fix the outer layer and the inner layer over the total height range, and are located avoiding air intake holes formed in the outer layer in a substantially symmetric manner with respect to the axis of the container to allow the outside air to enter between the outer layer and the inner layer. The adhesive bands 4 are located opposite to each other with a parting line 5 as a boundary, and the total width of the lower edge of one adhesive band 4 in the bottom seal part 10 of the bottom part squeezed flat by a pinch-off part of a blow split die is located opposite to the lower edge of the adhesive band 4 on the opposite side in a one-to-one butting manner.</p> |
