发明名称 Calcium hydroxide package and method of forming same
摘要 A calcium hydroxide package and method of forming the package that includes a sealed vial containing a capsule having a connected needle forming a nozzle which is open at the discharge end. The capsule is prefilled with a predetermined amount of calcium hydroxide formulation that is confined within the capsule by an end plug that functions as a piston to extrude the calcium hydroxide formulation from the capsule and directly to the tooth when used. Disposed within the sealed vial containing the capsule, prefilled with the calcium hydroxide formulation, is a quantity of preservative liquid or distilled water saturated with calcium hydroxide to prevent dehydration or decomposition of the calcium hydroxide formulation during shipping or storage, and wherein the vial with the capsule and liquid sealed therein can be subsequently sterilized by gamma radiation to ensure sterility of the calcium hydroxide and to prevent growth in the sealed container containing distilled water. In another form of the invention, the packaged is formed as a tray having multiple chambers, each of which contains pre-loaded capsules and a quantity of preservative liquid whereby the respective chambers are sealed by an overlying cover sheet.
