A liquid material feeding container in which the number of parts is reduced while maintaining quality required for a rotational feeding container and assembly with a simple method is allowed so that the cost is reduced without changing impression of use compared to current products is provided. In the liquid material feeding container, a piston 18 is formed with a seal portion 18a at an outer periphery of a front portion thereof, 18a being sliding in contact with an inner wall of a housing portion 12 of a barrel body 10, and a cylindrical portion 18b having a pair of projections 36 comprised of a rib-shaped projection projected outward in a radial direction in an outer periphery of a rear end portion and a female thread portion 38 in an inner periphery thereof, and in an outer peripheral surface of the front portion extending frontward from the above-described operating portion 16a of the above-described rotating element 16, a male thread portion 40 which is mated with the female thread portion 38 of the above-described cylindrical portion 18b is formed, and in the above-described barrel body 10, a space of the housing portion 12 is formed in a frontward portion and a groove portion 42 with which the projection 36 in an outer periphery of the above-described cylindrical portion 18b is engaged is formed in a backward portion along an axial direction. |
