Abstract: A trigger-type liquid dispenser, in which an upright and inverted dual unit includes a joint member, a pipe holding member, and a valve body. The joint member includes a through hole, which may be closed by the valve body, a valve-body-holding wall portion, which accommodates the valve body above the through hole in a manner such that the valve body is displaceable upward and downward, and an opening portion, which is formed in the valve-body-holding wall portion. In the inverted position, the upright and inverted dual unit permits content liquid contained in a container to be supplied to the dispenser main body by passing content liquid through a flow path from opening portion, through the hole, to the flow path defined between the joint member and pipe holding member sequentially. The valve body is inserted through the opening portion to be accommodated in the valve-body-holding wall portion.
