Abstract
A dispenser for dispensing a viscous material contained in a flexible package includes a body extending along a longitudinal axis that has a first end, an opposite second end, a cavity configured to receive the flexible package, and a handle assembly coupled to the first end. The handle assembly has a fixed handle, a trigger pivotally coupled to the fixed handle, and a rod extending between the fixed handle and the trigger into the cavity. A plurality of dispensing valves are positioned at the second end of the body and configured to dispense the viscous material, and a piston is movably disposed in the cavity for engagement with the flexible package. As the trigger is pivoted toward the fixed handle, the rod moves along the longitudinal axis toward the piston such that the piston engages the flexible package and the viscous material dispenses through the plurality of dispensing valves.
