Abstract

PURPOSE: To eliminate a screw structure and make an activation member compact for commercial distribution, and maintain a required stroke distance for pumping action by engaging a hook suspended from a pumping-down head with a mouth ring and a vertical groove with which the hook cannot be engaged, on the mouth ring. CONSTITUTION: An engagement part 24 at the lower end of a hook 23 is caused to engage with the lower end outer edge of the outer peripheral wall 12 of a mouth ring 10 and thus an activation member 15 becomes engaged with the pumping-down position of the activation member 15. Consequently, the height of a liquid discharger is small which contributes to the ease of handling in commercial distribution. When using this liquid discharger, the top of the hook 23 is pumped down so that the hook 23 is pressed against the top lateral side of a head peripheral wall 21 and an engagement part 24 is removed from the outer peripheral wall 12. In addition, a pumping- down head 18, i.e., the activation member 15 is turned against the mouth ring 10, so that the lower part of the hook 23 becomes positioned in a vertical groove 13. As a result, the engagement part 24 cannot engage with the outer peripheral wall 12 and the activation member 15 ascends as it is energized upward. In this state, it is possible to activate the pump by pressing down the pumping-down head 18.
