Abstract
A cartridge system for multi-component reactive viscous fluids which includes a plurality of syringe elements conjoined and discharging into an outlet having a matching plurality of outlet passageways therein. The cartridge has a frangible cap that seals the outlet passageways prior to use, is broken away from the outlet for dispensing and has plugs insertable into the passageways to reseal the cartridge after use. The plugs preferably have lead-in chamfers and a sealing ledge. Orientation means are provided to prevent cross-contamination upon resealing. A cooperating dispenser gun incorporates registration and retention means to secure the cartridge in position and has an integral cap removal and retention tool.
