Claim:
A capsule for storing and dispensing dental material, comprising a cartridge for the dental material; and a nozzle, the nozzle being pivotable with respect to the cartridge between a first position in which the capsule is closed for storage and a second position in which the capsule is opened for dispensing the dental material; wherein one of the nozzle and the cartridge comprises a bearing member and the other one of the nozzle and the cartridge comprises a bearing shell, the bearing member and bearing shell forming a pivot; wherein the bearing member has a non-circular cross-sectional shape that matches the non-circular shape of the bearing shell in the first position and upon pivoting the nozzle from the first position to the second position, the shape of the bearing member mismatches the shape of the bearing shell to improve the seal between the bearing member and the bearing shell relative to the first position.
