-i- Present day amalgam carriers include a separate spring member for urging the dispensing lever to its original position after serving to dispense the amalgam or restorative material into a prepared cavity, for example. Fracturing of the spring member occurs periodically and replacement thereof in the carrier, even if replaceable, is a time-consuming and frustrating operation and demands digital dexterity. The present invention provides an improved amalgam carrier wherein the spring and dispensing lever form an unitary member which requires infrequent replacement, if any, and when so replaced, or any other replaceable component of the carrier, may be done with comparative ease. |
