Dispenser cartridge for two component system

A dispenser cartridge containing two components of a two-component system, in a pre-determined ratio, said components having degrees of compressibility substantially equalized with one another, and comprising

• first and second co-axial chambers defined by an inner cylindrical container wall and an outer cylindrical container wall enclosing predetermined volumes in said predetermined ratio for containing respective first and second components and said chambers defining a dispensing end;
• first and second components of said two-component system, located in respective said chambers, said components having degrees of compressibility substantially equalized with one another;
• piston means moveable along said chambers for ejecting the respective components;
• a dispensing end wall extending transversely of said chambers;
• an elongated valve body formed on the outward side of said dispensing end wall said valve body;
• a transverse generally frusto-conical valve recess formed transversely in said valve body;
• a first dispensing opening in said dispensing wall communicating between said inner chamber and said valve recess;
• a second dispensing opening formed in said dispensing wall communicating between said outer chamber and said valve recess offset from said central axis of said inner chamber;
• a boss formed on said valve body and defining an axis located along the central axis of said inner chamber said boss defining two gernerally parallel dispensing passageways;
• a partition wall extending between said dispensing passageways whereby to keep said two components separate from one another;
• first and second valve openings extending between said valve body and said boss, said first valve opening communicating with one of said dispensing passageways, and said second opening communicating with the other of said passageways, and said first and second valve openings being located on opposite sides of said axis of said boss and being sized in said predetermined ratio;
• a valve plug member of frusto-conical shape shaped and adapted to be received in said valve recess;
• first and second valve conduits formed in said valve plug member, said first conduit defining two ends and being adapted to communicate between said dispensing opening in said dispensing wall and said first valve opening, and said second conduit defining two ends and being adapted to communicate between said second dispensing opening and said second valve opening, and wherein said conduits are of unequal length, and wherein each of said conduits defines a predetermined volume in said predetermined ratio;
• a plurality of valve annular ridges on said plug member formed therearound, extending around both ends of said first conduit, and around both ends of said second conduit therein, and, annular valve seal grooves formed in said frusto-conical valve recess registering with respective said ridge seals and co-operating therewith for sealing between respective first and second openings.
