A discharge container comprising a container main body, a discharge pump for discharging a contained liquid from a nozzle, and a fixing cap, wherein

• the discharge pump comprises a cylinder member made of a large-diameter cylinder and a small-diameter cylinder having an inlet pipe at a lower end, a piston member mounted on the cylinder member, and a nozzle head,
• the piston member comprises:
• a piston engaged with the small-diameter cylinder internally so as to slide freely;
• a poppet valve engaged with the piston;
• a piston guide engaged with an upper end of the piston;
• an air piston which is provided with an inner tube portion engaged with the outer circumference of the piston guide, an upper wall portion, an upper outer tube set upright at the upper wall portion and a sliding tube portion engaged with the large-diameter cylinder internally so as to slide freely, thereby forming an air chamber inside the large-diameter cylinder;
• and
• a stem which is provided with a lower tube portion engaged with an upper part of the piston guide to form a gas-liquid mixing chamber including a ball valve inside the upper part of the piston guide and engaged with the upper part of the inner tube portion so as to slide freely, an upper tube portion on which a sealing tube is installed consecutively, and a mesh ring mounted on the upper inner circumference;
