The present invention is directed to an apparatus for dispensing a two-part adhesive. The apparatus includes a cartridge body having two vessels for containing separate liquid components, respectively. Each vessel has a corresponding nozzle with an orifice in fluid communication with the corresponding vessel. The apparatus also has a cap frangibly connected to the nozzles to seal the orifices prior to opening the vessels. The cap is constructed so that separation from the nozzles opens the orifices. Once disconnected, the cap is removably securable to the nozzles. The cap also has a receptacle that conforms to the profile of the nozzles to prevent cross-contamination of the liquid components.

Apparatus for dispensing a two-part mixture, comprising: a cartridge body comprising a pair of vessels for containing first and second liquid components, respectively; each one of said vessels having a nozzle defining a dispensing orifice in fluid communication with an interior portion of its respective vessel within which one of said first and second liquid components is contained; a single cap integrally formed with both of said nozzles of said vessels so as to define frangible seals, upon first portions of said single cap, with said nozzles of said vessels for sealing said dispensing orifices of said nozzles prior to opening said vessels whereupon breakage of said frangible seals and separation of said single cap from said nozzles, said dispensing orifices of said nozzles are opened; said single cap being removably securable upon said nozzles subsequent to separation of said single cap from said nozzles so as to be capable of repeatedly covering and resealing said dispensing orifices of said nozzles; and said single cap having orientation means defined upon second portions thereof for preventing cross-contamination of said first and second liquid components contained within said vessels by ensuring that when said single cap is secured upon said nozzles of said vessels so as to cover and reseal said dispensing orifices of said nozzles, said second portions of said single cap can only be secured upon said nozzles of said vessels in a single predetermined orientation whereby first and second sections of said single cap originally secured and sealed, respectively, upon first and second ones of said nozzles so as to cover and reseal first and second ones of said dispensing orifices of said first and second nozzles cannot be subsequently secured and sealed, respectively, upon said second and first ones of said nozzles so as to cover and reseal said second and first ones of said dispensing orifices of said second and first nozzles.
