UNIT DOSE LIQUID DISPENSING AND PACKAGING FOR DENTAL APPLICATION

摘要

A nozzle for storage and application of liquid dental material, such as prim er or adhesive, to a preparation site at a patient's teeth, gums or mouth. The nozzle includes a hollow nozzle for containing the liquid dental material. T he hollow nozzle can include a flocked, open tip through which the liquid denta l material is dispensed. The nozzle also includes a storage block having a plurality of cavities formed therein. A plurality of hollow nozzles can be inserted into the cavities to form substantially air-tight seals between the open tips of the hollow nozzles and the exterior of the cavities. An end of the hollow nozzles opposite from the open tip and exposed above the block includes a breakable seal. Accordingly, the hollow nozzles can be stored in the block for an extended period of time. To apply the liquid dental materia l to a preparation site, an applicator can be attached to the end of the hollo w nozzle exposed above the block. The applicator is adapted to break the breakable seal and force the liquid dental material from the interior of the hollow nozzle through the open tip and onto an application site.
