PROBLEM TO BE SOLVED: To provide a blow-molded container capable of extracting content with a smooth squeeze feeling until completion of usage and regulating volume-reducing deformation of an inner layer stably throughout usage period and securing an extraction passage of content stably.SOLUTION: On a part of a side wall of a trunk (4), a crimp part (7a) is formed intermittently or continuously to a holding part (7) which is a vertical protrusion shape and holds a part of an inner layer (2) with an interposing state at a part of an outer layer (1). The crimp part (7a) is formed by pressure-welding a middle part of the holding part (7) from both sides in a horizontal direction and is tightly integrated so that it is not removable. |
