Abstract
A cartridge having a plunger cylinder with an external diameter smaller than a piston cylinder internal diameter. The cartridge has a plunger cylinder adapted to fit within a breach opening of a syringe. The piston cylinder having a larger internal diameter than the external diameter of the plunger cylinder, the cartridge is capable of holding a larger volume of material in the piston cylinder than could be held in the plunger cylinder fitted within the syringe breach opening. A piston placed in the piston cylinder has a concave surface.
Claims15
A cartridge for dispensing a material comprising:
- a plunger cylinder having a first external diameter and having a first bore with a first internal diameter;
- a plunger placed within the first bore of said plunger cylinder;
- a piston connecting to one end of said plunger, said piston having a second external diameter larger than the first internal diameter;
- and
- a piston cylinder having a second bore with a second internal diameter, said second internal diameter being larger than the first external diameter of said plunger cylinder, the second bore of said piston cylinder coaxially coupled to the first bore of said plunger cylinder, and said piston placed within the second bore of said piston cylinder,
- whereby a larger volume of material may be dispenses from the second bore than would be possible from the first bore for a common stroke of said plunger.
A cartridge for dispensing a material comprising:
- a plunger end having a plunger cylinder external diameter;
- a piston end having a piston cylinder internal diameter, and
- wherein the piston cylinder internal diameter is larger than the plunger cylinder external diameter.
A syringe and cartridge for dispensing a material comprising:
- a syringe having a barrel with a breach opening;
- a cartridge having a plunger end with a size to fit within the breach opening of said syringe;
- and
- wherein said cartridge has a piston end coupled to the plunger end, said piston end having a piston bore larger than the breach opening of the barrel of said syringe,
- whereby a larger volume of material may be dispenses from the piston bore than would be possible from a boar in the plunger end for a common stroke of a plunger.
