Abstract: A dental capsule container that can mix a first component and a second component in appropriate proportions. An annular fitting portion extending in a radial direction and a circumferential direction is formed at an end close to the operating portion of the piston portion of the piston member. An annular fitted portion fitted by the annular fitting portion is formed in a state in which the pressing rod portion opens the second discharge port by which the piston member is inserted in the second cylindrical portion of the chamber member in an inner circumferential portion adjacent to the third opening portion of the second cylindrical portion of the chamber member. The shape and dimensions of the annular fitting portion and the annular fitted portion are determined so that the fitting is not released due to an increase in inner pressure of the mixing portion.
