A liquid chemical dispensing device comprising a liquid chemical-use pail can able to be produced inexpensively and a simple-structure dispenser. The liquid chemical-use pail can (10) comprises a tubular inner container (1) of chemical resistant synthetic resin and an outer container (2) constituting the outer shell of the inner container (1). The inner container (1) has a mouth (11) opened to permit injection of liquid chemical. The dispenser (40) is provided with a plug body (41), a ventilating means (42) and liquid delivering pipe (43). The plug body (41) couples with the mouth (11) tight-sealingly. The ventilating means (42) has an opening (42b) communicating with the plug body (41) to permit compression liquid to pass into the inner container (1). The liquid delivering pipe (43) reaches the bottom surface of the inner container (1) at one end, protrudes from the plug body (41) at other end, and is fitted to the plug body (41) tigh-sealingly. Compression liquid is pressurized to an air layer in the inner container (1) via the ventilating means (42) to discharge liquid chemical from the other end of the liquid delivering pipe (43). |
