Patent ID: 6929157

Claim:
A viscous material dispenser system, comprising: a viscous material dispenser having a barrel with a plunger adapted to extend from a dispensing end of the barrel; a first tip assembly for retaining a viscous material container, said first tip assembly being attachable to and detachable from the dispensing end of the barrel of the viscous material dispenser and said first tip assembly containing a first actuator, the first actuator being biased such that an end of the first actuator contacts the plunger when the first tip assembly is attached to the barrel and an opposite end of the first actuator adapted for contacting a viscous material container when a viscous material container is retained in the first tip assembly such that movement of the plunger out of the dispensing end of the barrel causes the first actuator to move toward a dispensing end of the first tip assembly; wherein the dispenser further comprises a cooperating pair of handles that can be squeezed together, said cooperating pair of handles comprising a means for activating a viscous material cartridge containing a multi-component composition, said means comprising indentations on said pair of handles such that a first indentation on one handle is opposed from a second indention on an opposite handle, said first and second indentations formed to engage sides of the viscous material cartridge.
