Abstract
An applicator has a ratchet mechanism for dispensing material from a single or multiple barrel container. The ratchet mechanism includes a clutch that substantially prevents movement of a plunger of the applicator whenever a resistance to plunger movement is greater than a certain value. As a consequence, bursting of the container, or damage to components of the applicator, is substantially avoided. A resilient, integral pawl hinders unintentional rearward movement of the plunger and provides for a compact construction especially suitable for use in dispensing dental material.
