A dispensing assembly includes a double cartridge having two storage containers with bags placed therein, a mixer that is connectable to the cartridge, and an opening device acting upon the bag. The opening device is arranged on the mixer housing and rotatable with respect to the cartridge and has a cutting member including two knife-edges that acts essentially perpendicular to the longitudinal axis of the bags within the cartridge. Due to the knife-edges being rotatable and arranged laterally with respect to the bags, the cutting member allows a clean and predetermined opening of the bags and a dispensing operation with minimum pressure losses and lost volumes.

1. A dispensing assembly comprising: a cartridge that includes a cartridge housing and at least one bag placed therein, the bag being elongated along a longitudinal direction, the bag having a sidewall portion and an end portion, the sidewall portion extending essentially parallel to the longitudinal direction; andan opening device acting upon the bag, the opening device comprising a cutting member that is rotatable with respect to the cartridge about a rotation axis, the rotation axis being essentially parallel to the longitudinal direction, the cutting member extending radially outward from the rotation axis and including at least one knife-edge that is arranged and orientated thus as to effectuate a cutting movement that is essentially perpendicular to the rotation axis, the cutting member being arranged adjacent to the sidewall portion of the bag, the cutting member being configured to cut only a limited section of the sidewall portion, the limited section facing the rotation axis. 2. A dispensing assembly according to claim 1, further comprising an accessory having an accessory housing that is rotatable with respect to the cartridge, wherein the cutting member is connected to the accessory housing and actuatable by a rotation of the accessory housing. 3. A dispensing assembly according to claim 1, further comprising an accessory in a form of a mixer comprising a mixer housing and mixing elements that are connected to the mixer housing, wherein the cutting member is connected to the mixing elements. 4. A dispensing assembly according to claim 3, wherein the mixer housing includes actuating wings. 5. A dispensing assembly according to claim 1, wherein the cutting member is actuatable by a rotatably arranged ring. 6. A dispensing assembly according to claim 5, wherein the rotatably arranged ring includes actuating wings. 7. A dispensing assembly according to claim 1, wherein the cartridge is a double cartridge, the cutting member having one or two knife-edges. 8. A dispensing assembly according to claim 7, wherein the cartridge has an outlet flange including a circumferential groove, wherein the mixer has an inlet end including a bead, and wherein the bead is snapped in place in the circumferential groove. 9. A dispensing assembly according to claim 1, wherein the cartridge is a triple cartridge, the cutting member having one or a plurality of knife-edges. 10. A dispensing assembly according to claim 1, further comprising an accessory that is rotatable relative to the cartridge and is arranged on the cartridge in an axially secured manner. 11. A dispensing assembly according to claim 1, wherein the cartridge has at least one stop element configured to limit rotation of the cutting member. 12. A dispensing assembly according to claim 1, wherein the knife-edge extends essentially perpendicular to the rotation axis. 13. A dispensing assembly according to claim 1, wherein the cutting member is rotatable in a direction of rotation, and wherein the knife-edge essentially points in said direction of rotation. 14. A dispensing assembly according to claim 1, wherein the cartridge has at least one retaining element configured to retain the cutting member at a predetermined angle of rotation. 15. A dispensing assembly comprising: a cartridge that includes a cartridge housing and at least one bag placed therein, the bag defining a longitudinal axis; andan opening device acting upon the bag, the opening device comprising an actuating rod that is guided in the cartridge housing for linear displacement with respect to the cartridge housing, the actuating rod extending through an opening of the cartridge housing and having a handle outside of the cartridge housing, the opening device further comprising a cutting member arranged on the actuating rod, the cutting member including at least one knife-edge that is arranged and orientated thus as to effectuate a cutting movement to open the bag when the handle of the actuating rod is pulled away from the cartridge housing, the cutting movement being essentially perpendicular to the longitudinal axis of the bag. 16. A dispensing assembly according to claim 15, wherein the cutting member is arranged laterally with respect to the bag. 17. A dispensing assembly according to claim 16, wherein the bag has a sidewall portion and an end portion, the sidewall portion extending essentially parallel to the longitudinal axis, and wherein the cutting member is configured to cut the sidewall portion of the bag. 18. A dispensing assembly according to claim 15, wherein the knife-edge extends essentially perpendicular to the longitudinal axis of the bag within the cartridge. 19. A dispensing assembly according to claim 15, wherein the actuating rod is linearly displaced in a displacement direction when the actuating rod is pulled away from the cartridge housing, and wherein the knife-edge essentially points in said displacement direction. 20. A dispensing assembly according to claim 15, further comprising an accessory that is connectable to the cartridge. 21. A dispensing assembly according to claim 15, wherein the knife-edge extends essentially perpendicular to the actuating rod.
