TRIGGER-TYPE LIQUID JETTING DEVICE

PROBLEM TO BE SOLVED: To prevent unexpected leakage of content fluid by avoiding a piston from being pried by a load acting on a trigger lever during purchase, carrying, storage or the like of a liquid jetting device.SOLUTION: In a trigger-type liquid jetting device, a trigger lever 22 has a flat plate-like part 22F extending over a range from an operation part 221 to a pushing part 222, and both side edges of the flat plate-like part 22F forming at least the operation part 221 are provided with reinforcing side wall parts 22W, respectively. In the pushing part 222 of the trigger lever 22, pressure avoiding spaces 100 are formed on both lateral sides with respect to a to-be-pushed part of a piston 27, respectively.SELECTED DRAWING: Figure 3 【課題】液体噴出器の購入時、持ち運び時、保管時等に、トリガーレバーに作用する荷重によってピストンがこじられるのを回避し、内容液の不測の漏出を防止すること。【解決手段】トリガー式液体噴出器において、トリガーレバー２２は操作部２２１から押動部２２２に渡って延在する平板状部２２Ｆを有するとともに、少なくとも操作部２２１を形成する平板状部２２Ｆにはその両側縁に補強側壁部２２Ｗが設けられてなり、トリガーレバー２２の押動部２２２はピストン２７の被押動部に対する両側方に避圧空間１００を形成する。【選択図】図３
