PROBLEM TO BE SOLVED: To provide a thin-walled blow-molded bottle in which a pump can be fixed to an opening part and a buckling strength of a bottle barrel part is reinforced under utilization of a sucking pipe of the pump. SOLUTION: This thin-walled bottle A is molded with a synthetic resin of which resin weight per unit volume of the bottle A is 0.03 g/ml to 0.015 g/ml and a pump B can be fixed to its opening port. The pump B is comprised of a piston, a cylinder 31 and a suction pipe 34 suspended from the lower end of the cylinder 31. The lower end 35 of the suction pipe 34 of the pump B is contacted with an inner surface of the bottom wall of the bottle A to reinforce the buckling strength of the bottle A. |
