PROBLEM TO BE SOLVED: To provide a composite container with a jointing structure which is more stable than the prior art.SOLUTION: A paper-made outer package 3 is wound around the outer periphery of a plastic container 2. A bottom peripheral edge part 21 is formed on an outer peripheral lower part of the plastic container 2 so as to enter the inside in a peripheral form, and a folded part 31 is formed inward along a lower end of the paper-made outer package 3. A first jointing structure fixing the paper-made outer package 3 to the outer periphery of the plastic container 2 is constituted by fitting the folded part 31 to the bottom peripheral edge part 21. A protrusion 22 is formed on an outer peripheral upper part of the plastic container 2 so as to project outward, and a folded part 32 is formed inward along the upper end of the paper-made outer package 3. A second jointing structure fixing the paper-made outer package 3 to the outer periphery of the plastic container 2 is constituted by engaging the folded part 32 with the protrusion 22. The folded parts 31, 32 are in a crushed state. |
