<P>PROBLEM TO BE SOLVED: To provide a dental mixing apparatus for facilitating a work with a simple member configuration, where a content is prevented from leaking by push-out pressure from a part between a main body and a cylindrical body when pushing out the content sealed in the main body toward the cylindrical body. <P>SOLUTION: The dental mixing apparatus includes: the main body 110 with the content sealed therein; and the cylindrical body 130 freely rotatably attached to the main body. When the cylindrical body is rotated, the main body is shifted from a block state to a communication state, and then, the content is pushed out from the main body to the cylindrical body, so as to discharge the content from a discharge port arranged in the cylindrical body. In this case, through-holes for communication between the main body 110 and the cylindrical body 130, and rib grooves and rib in the circumferences of the respective through-holes are arranged, and the rib grooves and the ribs are kept in position, while linearly fitting each other. By the configuration, a fluid is prevented from leaking by the push-out pressure from a joint part between the main body 110 and the cylindrical body 130 when the content sealed in the main body 110 is pushed out toward the cylindrical body 130. <P>COPYRIGHT: (C)2010,JPO&INPIT |
