Device for dispensing flowable materials from a plurality of cartridge assemblies

A method for dispensing flowable materials from a plurality of cartridge assemblies, said method comprising:

• a. providing a dispensing device having a receptacle for carrying a plurality of cartridge assemblies therein, the dispensing device having a drive mechanism for moving an elongate drive rod in a direction parallel to the longitudinal axis of the cartridge assemblies, the drive rod having affixed at its distal end a web assembly including a plurality of ejectors extending therefrom arranged for reciprocal movement within the cartridge assemblies between a forward ejecting direction to dispense the flowable material therefrom and a return direction, the web assembly having at least one cutting surface disposed thereon;
• b. placing the cartridge assemblies into the receptacle of the dispensing device, the cartridge assemblies each having a dispensing nozzle and an elongated tubular wall portion formed of a material that can be cut by a cutting surface;
• and,
• c. actuating the drive mechanism to cause the at least one cutting surface to cut the tubular side wall of each cartridge assembly to permit the ejectors to move in the forward ejecting direction to dispense the flowable material from within the cartridge assemblies.

A device for dispensing flowable materials from a plurality of cartridge assemblies, said device comprising:

• a. means for carrying a plurality of cartridge assemblies therein, said cartridge assemblies each having a longitudinal axis and including a dispensing nozzle and an elongated tubular wall portion for containing a flowable material therein for dispensing, said wall portion being formed of a material that can be cut by a cutting surface;
• b. drive means for moving an elongate drive rod in a direction parallel to said longitudinal axis;
• c. a web assembly secured to said drive means, said web assembly including a plurality of ejection means extending therefrom, each ejection means arranged for reciprocal movement along said longitudinal axis within one of said plurality of cartridge assemblies between a forward ejecting direction to dispense the flowable material contained therein and a return direction;
• and,
• d. disposed on said web assembly, means for slicing the tubular side wall of each cartridge assembly as said ejection means moves in said forward ejecting direction.
