Abstract

A cartridge system for application of a material has at least one cartridge having at least one cartridge has cartridge walls and one cartridge head each having at least one opening in each cartridge head, and a bracket that is arranged on the cartridge head or cartridge heads. A valve is mounted in rotatable manner in the bracket, wherein the valve has at least one passage through the valve that is connected to an outlet opening, wherein the valve, in a closed position, closes at least one opening of at least one cartridge, in particular all openings of all cartridges, in a sealed manner. The at least one passage is connected to the opening or openings in an open position of the valve such that the cartridge content can be squeezed out of the at least one cartridge through the outlet opening, and further wherein the valve can be transitioned from a closed position to an open position through a rotation of the valve.

Claims

1. A cartridge system for application of a material, the cartridge system comprising at least one cartridge, wherein the at least one cartridge comprises cartridge walls and one cartridge head each having at least one opening in each cartridge head, and a bracket is arranged on the cartridge head or cartridge heads, wherein a valve is mounted in rotatable manner in the bracket, wherein the valve comprises at least one passage through the valve that is connected to an outlet opening, in that the valve, in a closed position, closes at least one opening of at least one cartridge in a sealed manner, in that the at least one passage is connected to the opening or openings in an open position of the valve such that the cartridge content can be squeezed out of the cartridge or cartridges through the outlet opening, and wherein the valve can be transitioned from the closed position to the open position through a rotation of the valve.

2. The cartridge system according to claim 1, wherein each cartridge comprises at least one feed plunger opposite from the cartridge head for expelling the cartridge content through the opening, which feed plunger closes the cartridge or cartridges on the floor side.

3. The cartridge system according to claim 1, wherein cartridge system comprises at least one sealing ring in the valve on one or more opening or openings such that, with the valve being open, at least one fluid-tight connection from the opening in the cartridge or the openings in the cartridges to the passage or passages is or are provided.

4. The cartridge system according to claim 1, wherein a connector is arranged on the valve, wherein the connector comprises a fastening means for fastening a dispensing tube, the passage extends through the connector, and the outlet opening is arranged on the connector.

5. The cartridge system according to claim 4, wherein the fastening means is a thread, in particular an external thread.

6. The cartridge system according to claim 2, wherein a mobile rod is arranged parallel to the at least one cartridge, wherein the rod comprises a snap-in locking means on the side facing the valve, and an opposite snap-in locking means is attached at the cartridge wall or cartridge walls and acts in concert with the snap-in locking means of the rod in a manner such that a motion of the rod in the direction of the cartridge floor and therefore a motion of the feed plungers out of the cartridges is significantly hampered or prevented.

7. The cartridge system according to claim 6, wherein the cartridge wall or cartridge walls include at least one slit that commences at the cartridge floor and is arranged parallel to the rod, wherein a width of the slit or slits is sufficient to take up the fin or fins and a length of the slit or slits extends to at least half of the length of the cartridge.

8. The cartridge system according to claim 1, wherein a dispensing tube is arranged on the valve or the connector, whereby the dispensing tube commences on the outlet opening and extends the passage to a dispensing tube tip.

9. The cartridge system according to claim 8, wherein the dispensing tube comprises a fastening means through which the dispensing tube is connected to the fastening means of the connector in a detachable manner or through which the dispensing tube is connected to the valve in a fixed manner.

10. The cartridge system according to claim 8, wherein the dispensing tube comprises a static mixer.

11. The cartridge system according to claim 8, wherein the dispensing tube, with the valve being closed, is arranged parallel to the at least one cartridge or between at least two cartridges.

12. The cartridge system according to claim 1, wherein the valve, in the open position and in the closed position, is arranged in a press-fit manner over the openings on the cartridge heads and closes these in a sealed manner or connects them in a sealed manner to the passage or passages.

13. The cartridge system according to claim 1, wherein the cartridge system comprises at least two cartridges, which are arranged to be parallel to each other, for mixing and applying a mixing ware.

14. The cartridge system according to claim 13, wherein the passages in the valve connect the openings of at least two cartridges to the outlet opening when the valve is in the open position.

15. The cartridge system according to claim 1, wherein the valve is cylinder-shaped, takes the shape of a cylinder with an elliptical base or the shape of a section of a cylinder.

16. The cartridge system according to claim 1, wherein the material is medical cement.

17. The cartridge system according to claim 6, wherein the mobile rod is arranged between at least two cartridges.

18. The cartridge system according to claim 1, wherein the cartridge system comprises at least three cartridges, which are arranged to be parallel to each other, for mixing and applying a mixing ware.

19. The cartridge system according to claim 6, wherein the mobile rod is arrange in a hollow body about which multiple cartridges are arranged to be parallel.

20. The cartridge system according to claim 6, wherein the mobile rod is arranged parallel to the feed plungers and fixedly connected to the feed plungers through at least a fin or a plate.
