First Claim
Patent Images
1. A carpule to store lower dosage amount of dental anesthetic comprises:
- a tubular extrusion;
a stopper;
a front cap;
a color-coded band;
the tubular extrusion comprises a front-half portion, a rear-half portion, a front opening, a rear opening, an outer annular surface, and an inner annular surface;
the stopper comprises an elongated body, a first extremity, a second extremity, and a plurality of circular tabs;
the front cap comprises an inner diaphragm, an outer-sealing ring, and a central opening;
the front opening and the rear opening being oppositely positioned from each other along the tubular extrusion;
the front cap being adjacently connected with the front opening; and
the stopper being slidably engaged with the rear opening.

Abstract
A carpule to store lower dosage amount of dental anesthetic solution includes a tubular extrusion, a stopper, a front cap, and a color-coded band. The front cap is connected with a front opening of the tubular extrusion while the stopper is slidably engaged with a rear opening of the tubular extrusion. An inner diaphragm of the front cap is exposed through a central opening of the front cap so that the dental needle can be traversed into the tubular extrusion through the inner diaphragm. Additionally, the cross-sectional diameter of the central opening is similar to the cross-sectional diameter of the front opening so that the front cap is able to provide an expanded surface area for the dental needle to traverse through.
