TRIGGER TYPE LIQUID INJECTOR

Japanese Patent JP3883164

B2

PROBLEM TO BE SOLVED: To cause a stopper member to be moved up and down through turning operation of a nozzle cap and make a trigger operation impossible at its second specified position in a trigger type liquid injection container arranged such that the nozzle cap rotatably fitted to the front segment of an injection cylinder through a coupling tube can inject liquid through operation of a trigger at its first specified position and a liquid injection passage is closed at its second specified position.
SOLUTION: A raised plate 22 of a stopper member 21 is freely fitted to an outer surface of a coupling tube segment between a partition plate 8 of a coupling tube 7 and a nozzle cap 12, an engaging plate 24 is passed through a through hole 31 of a trigger 5 to cause a rear end surface to be engaged with a front surface of lower segment of a cylinder 3 and at the same time the rear end of a lateral mounting plate 32 projected from a lower edge of the through-pass hole in a rearward direction is engaged with a forward step 25 of a lower surface of the engaging plate, an engaging rod 34 projected from the rear surface of the nozzle cap in a rearward direction is engaged with an inner surface of a fitting hole of the aforesaid raised plate to enable the stopper member 21 to be lifted up through turning of the nozzle cap.
