<P>PROBLEM TO BE SOLVED: To stop the operation of a pressure piston to prevent the injection of a solution even if unprepared pressure force acts on the operation lever of a trigger member in a liquid injection container equipped with a trigger type liquid injection device. <P>SOLUTION: The insertion port 5a of a jet nozzle is opened to the upper part of the operation lever provided to a trigger body 4 having an almost oval shape in a protruded state and the piston member 3 is fitted in a pressure cylinder 9 vertically provided in a container body in a slidable manner to be inserted in the insertion port to be integrated with the trigger body 4. A trigger device 1 thus constituted is attached to a cylindrical mounting body provided with a fitting cylindrical part 2c in which the piston is fitted in the slidable manner and a support member 2d for holding the trigger member in a rotatable manner and also used as a lid body 2 to constitute the subject trigger type liquid injection device wherein an operation member is formed in a freely shakable manner and the cylindrical piston is fitted in the pressure cylinder 9 in a freely slidable manner. A stop member 7 for stopping the shaking of the operation lever 6 is provided to the central part of the side wall of the device body of the trigger type liquid injection device in a rotatable and freely detachable manner to stop the shaking of the trigger member. <P>COPYRIGHT: (C)2003,JPO |
