Abstract
An improved applicator for soft materials includes a cartridge section and a relatively rotatable body section, the soft material being contained within the cartridge section and a plunger being provided to advance the soft material. The improvement resides in providing an assembly within the applicator body to prevent the inadvertent separation of the cartridge section from the body section. In a preferred embodiment, this assembly comprises a clutch means between the rotatable body section and the plunger whereby rotation of the body is transmitted to the plunger to advance and retract the plunger and associated soft material, the clutch means being designed so as to disengage before the plunger is retracted to the point at which it would forcibly separate the cartridge from the body.
