A container body (11) is provided with a squeeze operating portion (13a) between a shoulder portion (15) and a bottom portion (14), the squeeze operating portion including a squeeze face portion (16) opposed to a squeeze direction X, a pair of lateral support wall portions (17) arranged along the squeeze direction X at both side sections of the squeeze face portion (16), and inclined linking face portions (18) arranged as being inclined therebetween. When the squeeze face portion (16) is compressed to the squeeze direction x, the inclined linking face portions (18) expand distance between the pair of lateral support wall portions (17) at both sides as deforming along the squeeze face portion (16) from an inclined state against the squeeze face portion (16). The inclined linking face portions (18) are restricted so as not to be flipped in the squeeze direction (x) side after deformation completes as expansion force vanishes, so that constant quantity of content liquid is discharged.

1. A fixed quantity discharge squeeze container, comprising: a plastic-made squeeze-deformable container body to discharge a specific quantity of content liquid from a discharge opening with squeeze deformation of the container body, wherein the container body comprises a squeeze operating portion between a shoulder portion and a bottom portion in a vertical direction, the squeeze operating portion comprising a squeeze face portion arranged as being perpendicular to or approximately perpendicular to a squeeze direction, a pair of lateral support wall portions arranged along the squeeze direction at both side sections sandwiching the squeeze face portion, and inclined linking face portions which project the squeeze face portion to the direction opposite to the squeeze direction against the pair of lateral support wall portions as being arranged between the squeeze face portion and the lateral support wall portions;the inclined linking face portions are arranged as being continued from the squeeze face portion and the lateral support wall portion via joint edge lines extending in the vertical direction;the joint edge lines form vertexes with lower and upper edge lines provided between the squeeze operating portion and respective ones of the bottom portion and the upper portion, the lower and upper edge lines extend in a horizontal direction, and the joint edge lines extend in the vertical direction from the lower edge line to the upper edge line; andareas of the inclined linking face portions adjacent to a predetermined position expand a distance between the pair of lateral support wall portions of both sides at sections of the joint edge lines against the inclined linking face portions as deforming along the squeeze face portion from an inclined state against the squeeze face portion when the predetermined position of the squeeze face portion is compressed to the squeeze direction with application of an expansion force, such that the inclined linking face portions deform by bending at the joint edge lines when the expansion force is applied, while the inclined linking face portions are restricted so as not to be flipped in the squeeze direction side after deformation completes as the expansion force is removed, so as to prevent occurrence of variation in squeeze deformation quantity of the container body among repeated squeeze operations performed by applying the expansion force to the predetermined position. 2.
