To provide a delivery container rapidly discharging air bubbles in a container body.

A cylindrical piston member 20 is vertically fitted in a cylinder member 10. An operating member 30 having a delivery passage is penetrated on the inner circumference of the piston member in a non-drawable manner via a locking member 32. A suction valve of a ball valve 15 is formed between an elastic piece 17 provided on a lower end of a fitting cylinder 16 on a bottom wall of the cylinder member and the bottom wall of the cylinder member. A spring member 35 for upwardly urging the operating member is provided between the upper end of the fitting cylinder and the locking member. The piston member and the operating member slide with respect to the cylinder member, and the piston member is engaged with a second upwardly stepped portion 11a of the cylinder member, and the locking means is separated downwardly from the piston member to deliver a liquid content in the cylinder member via the delivery passage by opening the delivery passage. The liquid content in the container body is sucked in the cylinder member by opening the suction valve through the sliding of the piston member and the operating member in the opposite direction of the cylinder member.
