    摘要: A dispensing syringe for dispensing a multi-component dental composition, preferably a two component composition, is provided. The syringe includes a syringe body with multiple elongated barrels for storing the components of the composition; a threaded plunger rod assembly; and a rotatable, threaded connector knob. Preferably, the syringe body has a double-barrel structure and the plunger rod assembly includes two plunger rods that slide within the barrels. The threaded knob has a through-bore with a continuous internal thread for engaging the outer threads of the first and second plunger rods. A dental practitioner manually rotates the knob to displace the first and second plunger rods and discharge the components. The dispensing syringe may further include a dispensing tip containing a static mixing element for mixing the components and dispensing the mixed composition.

    摘要: An aerosol delivery system for dispensing a multi-component dental composition is provided. The system is particularly suitable for dispensing dental impression material containing mixed components A and B. The system includes a dispensing device having an inner container with pressurized aerosol chambers. The first chamber is used for storing and dispensing component A, and the second chamber is used for storing and dispensing component B. The dispensing device includes a piston assembly having a first piston member that slides within the first chamber and a second piston member that slides within the second chamber. The pistons force the components into a common manifold, and the combined material is fed into a dispensing tip containing a static mixer, wherein the material is mixed and then dispensed.

    摘要: A package (10) for the storage and dispensing of a plurality of materials includes a first and a second longitudinally juxtaposed barrels (11, 12). Each barrel (11, 12) having a first and a second end (20, 21). Each first and second barrels (11, 12) having a quantity of at least one of the materials initially contained therein, and each barrel having an open end (20) and a dispensing end (21). A sealing plunger (40) disposed in each barrel (11, 12) such that the material in each barrel (11, 12) is initially positioned between the dispensing end (21) of the barrels (11, 12) and the respective ones of the sealing plungers (40). A snap cap (23) is contiguously formed to initially close each of the dispensing ends (21) of the barrels (11, 12), such that the snap cap (23) may be broken from the barrels (11, 12) to thereby forming a secondary open end (22) at the dispensing end (21) of the barrels (11, 12), thereby facilitating the material contained in each barrel (11, 12) to flow through and be dispensed.
