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. |

1. A trigger-type liquid dispenser comprising a dispenser main body that is attached to a mouth of a container and that includes a pump, an upright and inverted dual unit that permits supply of a content liquid contained in the container to the dispenser main body regardless of whether the container is in an upright position or an inverted position, and an operation lever that is supported swingably by the dispenser main body and that is configured to actuate the pump, wherein the dispenser main body draws, pressurizes, and force-feeds the content liquid supplied from the upright and inverted dual unit and dispenses the content liquid through a nozzle attached to the dispenser main body due to actuation of the pump in response to pulling of the operation lever, and wherein
the upright and inverted dual unit includes a joint member that is attached to the dispenser main body, a pipe holding member that is attached to the joint member and that holds a drawing pipe suspended in the container, and a valve body, the joint member includes a through hole that is closable from above by the valve body, a valve-body-holding wall portion that accommodates the valve body above the through hole in a manner such that the valve body is displaceable upward and downward and is prevented from slipping off, and an opening portion that is formed in the valve-body-holding wall portion, in the inverted position, the upright and inverted dual unit permits the content liquid contained in the container to be supplied to the dispenser main body by passing the content liquid through a flow path from the opening portion, the through hole, to a flow path defined between the joint member and the pipe holding member sequentially, and in the upright position, the upright and inverted dual unit permits the content liquid to be supplied from the drawing pipe to the dispenser main body by the valve body closing the through hole, and the valve body is inserted through the opening portion to be accommodated in the valve-body-holding wall portion. |
