PROBLEM TO BE SOLVED: To suppress a liquid outside a container main body from accidentally flowing in an air cylinder, and discharge the liquid such as water and a content liquid accidentally flowing in the air cylinder during use.SOLUTION: A guide surface 53, which extends downward gradually from an outer side to an inner side in a radial direction, and of which an end part on the inner side in the radial direction reaches an upper end opening part of a liquid cylinder 26, is formed on a bottom part 28a of an air cylinder 28. A pump 13 includes an air passage 36 which guides air in the air cylinder 28 to a gas-liquid mixing chamber 29. An abutment part 37, which projects outside in the radial direction from a stem 12, abuts on a lower end of an insertion cylinder part 32, and blocks communication between an inside of the gas-liquid mixing chamber 29 and an inside of the air cylinder 28 through the air passage 36, is formed on the stem 12. The abutment part 37 is arranged in the liquid cylinder 26 in a state that it separates from the lower end of the insertion cylinder part 32 and communicates between the inside of the gas-liquid mixing chamber 29 and the inside of the air cylinder 28 through the air passage 36 when the stem 12 is descended. |
