PROBLEM TO BE SOLVED: To provide a constant-volume discharging squeeze container which discharges content liquid by a constant volume by carrying out restriction so that variation is not generated in the squeeze deformation amount by arranging only the shape of a container main body. SOLUTION: The container body 11 has: a squeeze surface part 16 opposed to a squeeze direction X between a shoulder part 15 and a bottom part 14; a pair of lateral-surface supporting wall parts 17 disposed along the squeeze direction X at the parts in both sides of the squeeze surface part 16; and a squeeze operating part 13a including oblique coupling surface parts 18 obliquely provided therebetween. When the squeeze surface part 16 is squeezed in the squeeze direction X, the oblique coupling surface parts 18 are deformed from the state in which they are oblique with respect to the squeeze surface part 16 so as to fit along the squeeze surface part 16. During the deformation, the parts 18 push and expand the distance between the pair of lateral-surface supporting wall parts 17 in both sides. After the oblique coupling surface parts 18 are deformed until there is no more pushing/expanding force, the container is restricted so as not to be inverted to the squeeze direction X-side, and the constant volume of the content liquid is discharged.
