To provide a maloperation preventive mechanism for a trigger dispenser which is capable of physically and visually preventing maloperation and making the dispenser compact by springing up a trigger lever.
The trigger lever 11 is divided nearly in an intermediate part and is composed of an upper lever section 12 and a lower lever section 13. The lower lever section 13 is connected to this upper lever section 12 in such a manner that the lower lever section 13 may be sprung up and integrally withdrawn by means of a turning pin 14. A detaining member 16 for holding the sprung up state of the lower lever section 13 is disposed between the upper lever section 12 and the lower lever section 13. As a result, the lower lever section 13 is sprung up to prohibit the injection operation and the integral operation is made possible and the sprung up state may be maintained by the detaining member 16 when the lower lever section 13 is returned to its home position. Even more, the trigger dispenser is made compact by dividing the trigger lever in the intermediate segment and connecting both.
