PROBLEM TO BE SOLVED: To eliminate residue of contents being unable to be discharged for a pump-equipped bottle in laminated structure for which the inner layer of the bottle contracts, being separated from the outer layer, as the quantity of contents decreases. SOLUTION: The bottle main body is made up by separably laminating an inner layer 12 to the inside of an outer layer 11. The outer layer 11 and the inner layer 12 are joined together only at a joining part 13. Two platelike fins 27, 27 are provided at a pressurizing part 22b of a pouring pump inserted into the bottle main body through its mouth. As the inner layer 12 separates from the outer layer 11 and contracts, the inner layer 12 is wound round the pressurizing part 22 and the fins 27, 27, and the remaining part of the inner layer 12 is folded up on a position near the joining part 13. |
