PROBLEM TO BE SOLVED: To provide a liquid discharge container in which a configuration of a discharge valve is simplified and a number of components of the discharge valve is reduced.SOLUTION: A discharge valve 100 comprises: an attachment cylinder 101 which is attached to a discharge pipe 50 so as to be movable downward, in an upward energized state; a first seal part 120 which is externally fitted to the attachment cylinder in a liquid tight state and capable of slide vertically; and a cylindrical second seal part 121 which projects downward from the first seal part, integrated with the first seal part, and forms a communication space 125 between it and the attachment cylinder in a state of surrounding the attachment cylinder from outside of a radial direction. The attachment cylinder comprises: an attachment cylinder body 110 to whose upper end, a discharge head 56 is attached; and a valve seat part 111 projecting outward from the attachment cylinder body in the radial direction, to which a lower end opening edge of the second seal part contacts in a liquid tight state, thereby blocking communication between insides of the communication space and discharge pipe. The attachment cylinder body has a communication hole 110a for communicating inside of the attachment cylinder body and communication space. A liquid discharge container 1 has the above-mentioned structures.SELECTED DRAWING: Figure 2 |
