    摘要: A trigger-type liquid dispenser comprises a mounting sleeve (2) to be fitted onto a neck portion of a container body, a vertical sleeve (2a) erected from the mounting sleeve (2), an ejecting sleeve (3) projected forwardly from an upper end portion of the vertical sleeve (2a), a cylinder (4) projected forwardly from a middle portion of the vertical sleeve (2a), a plunger (6) slidably engaged in the cylinder (4) and being urged forwardly, a trigger (5) swingably attached to a front portion of the ejecting sleeve (3), a rear surface of an upper portion of the trigger (5) being engaged with an front end portion of the plunger (6), a nozzle fitting sleeve (7) fitted to a front end portion of the ejecting sleeve (3), and a nozzle head (8) rotatably fitted to an outer surface of the nozzle fitting sleeve (7), said nozzle head (8) being formed with a nozzle hole (10). Liquid stored in the container body is sucked up and ejected through the nozzle hole (10) by pulling the trigger (5) rearwardly. An arm (21) is projected rearwardly from an outer surface of the nozzle head (8). A first engaging portion (23) is provided at an upper portion of the trigger (5). A second engaging portion (26) is provided at a front surface of a lower portion of the cylinder (4). When the trigger (5) is positioned at its front-most position and the nozzle head (8) is rotated, a part of the arm (21) is detachably engaged with the first engaging portion (23), another part of the arm (21) is detachably engaged with the second engaging portion (26), so that the plunger (6) can not move rearwardly even if a user attempts to pull the trigger (5).
