Abstract
A disposable capsule for dispensing a dental material and a method of making the capsule wherein the capsule includes a reservoir portion containing a predetermined amount of material to be dispensed, and which reservoir is connected in communication with a discharge tip. Connected to the end of the tip and projecting therethrough is a needle cannula through which the material is ejected. A displaceable piston may be provided when material is desired to be sealed within the reservoir portion, and which forces the material through the cannula when displaced within the reservoir portion. The method of forming such capsule includes the step of flaring one end of the cannula radially outwardly and inserting the cannula with the flared end trailing into the reservoir and through the discharge tip. A force is then applied to the cannula to force the flared end to be imbedded into the material of the capsule adjacent the end of the discharge tip. The method insures the cannula connection within the tip end so as to permit the cannula to be rotatably mounted relative to the tip while maintaining a seal between the tip and the cannula.
