Abstract:
1. A structure for connecting a mixing tip to an impression material cartridge in which the impression material cartridge comprises a top connective plate formed on an upper central part of a pair of cylinders that are connected at bottom portions of the cylinders by a connective flange, and on a top surface of the top connective plate a connective socket is provided with ejaculatory holes that each connect to the cylinders; and at opposing sides of the top connective plate are mixing tip connective ends, the mixing tip connective ends are each formed with rotational connective grooves on an internal lower part of the mixing tip connective ends and are installed to face in opposing directions; the structure further comprising on a top central part of the structure, a mixing tube for the insertion of a mixing screw protrudes, and on a lower part of the structure, a connective structure of a mixing tip installed with a connective connector is formed with connective tubes that protrude downwards, each connective tube being connected with the ejaculatory holes on the connective socket of the impression material cartridge on an inside of the mixing tip and on protruding connective wings that each rotationally connect on the rotational connective grooves of the mixing tip connective ends of the impression material cartridge; and when the connective wings rotationally connect with the rotational connective grooves of the mixing tip connective ends of the impression material cartridge, on an end surface of the connective wings on the mixing tip, rotational bumps extending from the connective wings and which are positioned on sides of the mixing tip connective ends each form diagonal symmetry; and on a lower surface of the rotational bumps, cylindrical guide pins that guide the connective direction of the mixing tip are formed to be protruded downwards so as to extend downwardly from the rotational bumps and beneath lowermost end portions of the end surface of the connective wings and the rotational bumps; and on the sides of the top connective plate, a mixing tip connective guiding plate protrudes with diagonally symmetrical guide pin insertion strips disposed diagonally across from each other, guide pin guiding curves, and guide pin connective grooves, each of the guide pin insertion strips, guide pin guiding curves and guide pin connective grooves being formed along a side surface of the mixing tip connective guiding plate, the guide pin guiding curves and the guide pin connective grooves each comprising an arcuate configuration along said side surface of the mixing tip connective guiding plate so as to guide the cylindrical guide pins to connection with the guide pin connective grooves so that said cylindrical guide pins seat within and thereagainst said guide pin connective grooves upon connection of the mixing tip with the impression material cartridge; and upper internal surfaces of the ejaculatory holes on the connective socket of the impression material cartridge have an internal diameter formed in a taper format so as to narrow toward the mixing tip, and the connective tubes of the connective connector are formed with a width that narrows toward the cylinders, in which upon connection of the mixing tip to the impression material cartridge, portions of the connective connector and connective tubes thereof surroundingly seat directly atop, alongside and within portions of the ejaculatory holes such that portions of the mixing tip connective ends are disposed therebetween each of the connective connector and connective tubes thereof and the connective wings.
