<p>PROBLEM TO BE SOLVED: To correctly form an atmosphere introducing hole by forming a flat surface at a position to drill the atmosphere introducing hole on the outer circumference of a container mouth part, and forming a positioning stepped part to be raised from a bottom wall in a lamination blow formed article comprising an outer side layer and an inner side layer which is peelable from the outer side layer. SOLUTION: A lamination/separation blow container A having an outer side layer 1 and an inner side layer 2 is formed through lamination blow forming so as to be provided with a container body part 3, a mouth part 4, and a bottom part 5. The outer side layer 1 is made of a high density polyethylene resin, and the inner side layer 2 is made of a nylon resin, and formed as an inner bag which is peelable from the outer side layer 1 and freely deformable. In this container, a flat part 7 is provided at a position to drill an atmosphere introducing hole 8 at a lower part of a screw 6 part of the container mouth part 4. A projected bar 11 for bottom sealing in which a large number of biting parts 10 to be press fitted into an opposite fused layer are alternately provided is formed on the bottom part 5 of the container A, and a positioning stepped part 12 which is raised in a trapezoidal shape on either side of the projected bar 11.</p> |
