a cap attached to the collar via a hinge;
a continuous gasket is disposed between the collar and the cap;
an elongated plunger rod disposed within the barrel, the elongated plunger rod comprising a distal end and a proximal end, the distal end including a stopper slidably positioned in fluid-tight engagement with the inside surface of the barrel for drawing fluid into and driving fluid out of the chamber by movement of the stopper relative to the barrel, the elongated plunger rod extending outwardly from the open proximal end of the barrel; and
