ABSTRACT:
A trigger-type pump dispenser capable of preventing deformation of a channel of a coupling part when a piston is vertically pushed down by a trigger even in a structure in which the coupling part bends and a nozzle does not vertically move. The dispenser has a base main body1having the cylinder part11inside and attachable to an opening part of a container main body. A cover body4detachably latched with the base main body. A piston structure2composed of the nozzle part21engaged with the base main body, the piston part23, and a bendable coupling part coupling the nozzle part and the piston part. Many fins22A are formed on the periphery of the coupling part22so that an interior channel is not deformed.
