A dual-compartment adhesive dispensing cartridge comprises a pair of storage compartments for containing two different reactive components of, for example, an adhesive mixture. A pair of dispensing conduits are defined within a dispensing outlet portion by means of a divider wall which extends through the entire axial extent of the dispensing outlet portion so as to ensure that the two reactive components are maintained separate until the components are to be dispensed. A cap member comprises a pair of dependent plugs, and the cap member is initially integrally secured upon the upper end portion of the dispensing outlet portion by means of peripheral frangible connections which are defined between the plugs and the upper end portions of the dispensing conduits which define dispensing outlet ports. In addition, an axially oriented web member extends upwardly from a central region of the dispensing outlet portion, and the cap member is integrally secured to the upper extremity of the web member by means of another frangible connection. In this manner, when the cap member is to be separated from the dispensing cartridge, the integral connection defined between the cap member and the web member effectively serves as a pivotal fulcrum about which the cap member can be pivoted so as to impress tension and compression forces upon the frangible plug connections and thereby cause the clean and accurate fracture of the frangible plug connections so as to cleanly and fully uncover the dispensing outlet ports.
