Abstract
In one preferred embodiment, a body for a dual barreled syringe, said body including: two, parallel, cylindrical, hollow, cojoined, barrels having, respectively, open filling ends and closed discharge ends from which discharge ends axially extend discharge nozzles; and sealing apparatus, closing the discharge ends, formed monolithically with and sealing distal ends of the discharge nozzles, the sealing apparatus being manually severable from the distal ends of the discharge nozzles so as to open the discharge nozzles to permit the discharge therefrom of material held within the barrels, without the sealing apparatus being mechanically cut from the discharge nozzles. In another preferred embodiment, there is provided a plunger assembly for a dual barreled syringe, the plunger assembly including: two parallel plungers cojoined at first ends thereof against which manual pressure may be applied to force sealing members disposed at a second end thereof through barrels of a body of the dual barreled syringe to discharge materials from the barrels; and joining apparatus, spaced from the flange, attached to, extending between, and joining the plungers to maintain the plungers in relatively rigid, parallel alignment.
