<p>A trigger sprayer device is disclosed, which is configured in such a way that the trigger and plunger are operable only after unlocking, to be childproof. The trigger sprayer device includes: a plunger unit (52) that is placed to reciprocate inside the cylinder (65) and elastically supported by a restoring spring (51), in which the front end of the plunger unit (52) is associated with a rear side of the trigger (80) and the sides of the plunger unit (52) protrudently forms locking ribs; and a locking member (53) that is pivotally fitted in an opened end of the cylinder (65), and has a through hole (53a), shaped as a ring, to allow the front end of the plunger unit (52) to be past through, forming slide grooves (53b) on the inner circumference of the through hole (53a) to se¬ lectively allow the locking ribs (52g) to be moved. Therefore, when the slide grooves (53b) and the locking ribs (52g) are not parallel with each other, the trigger (80) and the plunger unit (52) maintain their locking state. Thus, the operation of the trigger (80) can be restricted. Ac¬ cordingly, the trigger sprayer device is childproof. In addition, since the plunger unit (52) has always been received in the through-hole (53a), the plunger unit (52) is not deformed although the trigger is pressed from both its sides and impacted while the sprayer is carried.</p> |
