Patent ID: 6877983

Claim:
A dental capsule providing reduced extrusion forces comprising: a body portion having a substantially constant first inside diameter, a body portion inside surface, and a body portion axis; a transition portion, adjacent said body portion, having a reducing inside diameter and a transition portion axis, said body portion axis intersecting said transition portion axis forming a non-zero body-transition angle, said transition portion having an upper transition surface intersecting at an angle with the body portion inside surface of said body portion and a lower transition portion segment surface coincident with a straight line formed by the body portion inside surface; and a discharge portion having a substantially constant second inside diameter, adjacent said transition portion, and having a discharge portion axis, said transition portion axis intersecting said discharge portion axis forming a non-zero transition-discharge angle, whereby high viscosity dental material is capable of being extruded with reduced extrusion force and without damaging the high viscosity dental material.
