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 device is provided to prevent cross-contamination upon resealing. A cooperating dispenser gun incorporates registration and a retention device to secure the cartridge in position and has an integral cap removal and retention tool.
Claims21
A cartridge system for simultaneously dispensing two component materials, comprising:
- (a) a cartridge having a pair of reservoirs, each for holding one of the two component materials;
- (b) an outlet disposed at an end of said cartridge, said outlet having two passageways therein, a first of said two passageways communicating with said first reservoir and a second of said two passageways communicating with said second reservoir;
- and
- (c) a cap having a pair of plugs extending from a surface thereof, said pair of plugs attached to said outlet with a first of said pair of plugs sealing said first passageway and a second of said pair of plugs sealing said second passageway, said first and second plugs being detachable from said outlet to permit dispensing the component materials, said first and second plugs being insertable into said first and second passageways, respectively, to reseal said cartridge after the materials have been dispensed, said pair of plugs being monolithically formed with said outlet and attached thereto by a frangible portion, said frangible portion breaking when said cap is detached from said outlet.
A cartridge system for simultaneously dispensing two component materials, comprising:
- (a) a cartridge having a pair of reservoirs, each for holding one of the two component materials;
- (b) an outlet disposed at an end of said cartridge, said outlet having two passageways therein, a first of said two passageways communicating with said first reservoir and a second of said two passageways communicating with said second reservoir;
- said reservoirs being in the form of a pair of parallel cylinders;
- (c) a cap having a pair of plugs extending from a surface thereof, said pair of plugs attached to said outlet with a first of said pair of plugs sealing said first passageway and a second of said pair of plugs sealing said second passageway, said first and second plugs being detachable from said outlet to permit dispensing the component materials, said first and second plugs being insertable into said first and second passageways, respectively, to reseal said cartridge after the materials have been dispensed;
- and
- (d) a dispenser gun with a cartridge tray for removably receiving and holding said cartridge, said dispenser gun having a pair of piston elements selectively moveable by actuator means for urging the two component materials from said reservoirs through said outlet, said tray having an end plate distal to said actuator means, said end plate having a cap removal tab formed therein, said cap removal tab insertable into an opening provided in said cap.
