  • Patent number: 11851263
    Abstract: A dental material container includes a cylindrical body that stores a dental material including a pair of opposing primary surfaces, and a rotatable cap covering the body. The cap includes an internal space capable of housing the dental material. The body includes a pair of first holders that are formed on an inner surface of the body to movably hold the primary surfaces of the dental material; the cap includes a pair of second holders formed inside of the cap to movably hold the primary surfaces of the dental material. When the cap is rotated in the circumferential direction relative to the body, a continuous space where the dental material is movable is formed by the first and second holders, the dental material located closest to the opening in the body moves into the cap, and the dental material moved into the cap is housed in the cap.
