PROBLEM TO BE SOLVED: To block the invasion of the air to an inverted flow passage, since an outer air for negative pressure preventive purpose led in at the time of inversion advances into the liquid of the head part in a container body in the inverted attitude being made in air bubbles, and enters an inverted passage, so as to deteriorate the spouting condition from a nozzle. SOLUTION: In this pump for use both in normally upright attitude and in inversely upright attitude, a lift pipe 4 is connected to the suction port 2 of a pump main body 1, through a suction passage automatic converting device 3, a regular flow passage 5 in which the lift pipe 4 is communicated to the suctiin port 2, and an inverted flow passage 6 in which a flow passage port 7 is provided at the adequate position on the peripheral surface of the concerned device, and communicating it to the suction port 2; are provided to a suction passage automatic converting device 3, while a passage converting means 8 to convert the both passages automatically according to their attitudes is provided, and at the same time, a trigger 9 is provided in the pump main body 1, so as to form an outer air leading-in passage 10 opened from the outer side into a container body B. In such pump for use both in normally upright attitude and inversely upright attitude, an air exhaust tube 11 whose lower end is opened is provided to cover the outside of the suction passage automatic converting device 3, so as to cover the flow passage port 7 allowable to communicate the liquid. |
