A pump dispenser container structure in which acidification prevention of contents, fixed quantity discharge and contents leakage prevention are possible is provided to automatically shut off a nozzle hole by a nozzle hole opening/closing structure when the content is not discharged, thereby preventing the air or impurities from flowing in. The pump dispenser container structure includes a nozzle head(10), a vessel housing(20), a piston shaft(30), a second valve shaft(40), a large piston(50), a piston housing(60), a piston shaft returning spring(70), a nozzle hole opening/closing structure fixing tool(100), a nozzle hole opening/closing structure(200), a loose type plastic elastic member(300), a piston(400) and a first valve(500). The nozzle hole opening/closing structure fixing tool(100) is installed around a nozzle hole(11). The nozzle hole opening/closing structure(200) is fixed on the nozzle hole opening/closing structure fixing tool(100). The loose type plastic elastic member(300) pushes an opening portion(41) of a second valve shaft(40).
