<P>PROBLEM TO BE SOLVED: To provide a pump constituted so as to suck the liquid in a container body by the up and down movement of a movable ejection part B to eject the same from a nozzle 83, capable of being locked with a fixed suction part A in a state that the movable ejection part B is pushed down and having no leak fear of the liquid not only in a case that the container body is allowed to fall but also in a case that the body part of the container body is strongly squeezed. <P>SOLUTION: In the lowermost falling locked state of the movable ejection part B, a seal part for cutting off the up and down movement in a cylinder A1 by the movable ejection part B and the fixed suction part A. Further, the closing cylinder member B4 mounted on the outer periphery of a stem B1 in an up and down movable manner closes an open air introducing hole 18 and, when the movable ejection part B is present at the uppermost rising position and moved up and down in order to eject the liquid, the seal part is opened and the open air introducing hole 18 is opened. <P>COPYRIGHT: (C)2012,JPO&INPIT |
