Dispensing device for multi-component cartridges
A dispensing device for a multi component cartridge includes a housing in which a reception element for receiving a cartridge end of the multicomponent cartridge is arranged. The cartridge end is located at the inlet side of a first and second storage container filled with a filling mass and respectively sealed in a fluid tight manner at the cartridge end by a respective piston. A plunger arrangement and a drive arrangement for moving the plunger arrangement are arranged in the housing. A movement of the plunger arrangement in a dispensing direction can be carried out by the drive arrangement for dispensing the filling mass from the storage containers of the multicomponent cartridge. The reception element has an axis of rotation which is substantially arranged in parallel to the dispensing direction. The cartridge end pushed into the reception element can be transferred from an assembly position into a dispensing position by a rotation about the axis of rotation.
1. A dispensing device for a multi component cartridge including a housing in which a reception element for receiving a cartridge end of the multicomponent cartridge is arranged, wherein the cartridge end is located at the inlet side of a first and second storage container filled with a filling mass and respectively sealed in a fluid tight manner at the cartridge end by a respective piston, wherein a plunger arrangement and a drive arrangement for moving the plunger arrangement are arranged in the housing, wherein a movement of the plunger arrangement in a dispensing direction can be carried out by the drive arrangement for dispensing the filling mass from the storage containers of the multicomponent cartridge, wherein the reception element has an axis of rotation which is substantially arranged in parallel to the dispensing direction, wherein the cartridge end pushed into the reception element can be transferred from an assembly position into a dispensing position by a rotation about the axis of rotation, the assembly position being different from the dispensing position, wherein the assembly position allows the cartridge end to be installed into and removed from the reception element whereas the dispensing position allows dispensing of the filling mass by movement of the plunger arrangement, the reception element is rotatably arranged in a guide element, and the reception element or the guide element has an abutment in order to limit the rotation between the assembly position and the dispensing position.
2. A dispensing device in accordance with claim 1 , wherein an angle of rotation from the assembly position into the dispensing position amounts to substantially 90°.
3. A dispensing device in accordance with claim 1 , wherein the guide element is arranged in the housing in an installed state and is inseparably connected to the housing in the installed state.
4. A dispensing device in accordance with claim 1 wherein the reception element is rotatably supported in the guide element in the housing.
5. A dispensing device in accordance with claim 1 , wherein the guide element is formed as a projection which can be received in a groove of the reception element.
6. A dispensing device in accordance with claim 1 , wherein, on assembly of the cartridge end and the reception element, longitudinal axes of the first and second storage containers are displaceable along a connection line between a second opening for the second storage container and a first opening for the first storage container.
7. A dispensing device in accordance with claim 1 , wherein the reception element has a guide groove for receiving the cartridge end.
8. A dispensing device in accordance with claim 1 , wherein the reception element has at least one of an abutment and a latching element for securing the multicomponent cartridge in at least one of the dispensing position and the assembly position.
9. A dispensing device in accordance with claim 8 , wherein a clicking sound can be emitted on latching, so that the latching is audible for the user.
10. A dispensing device in accordance with claim 8 , wherein the cartridge end can be inserted into the reception element and can be removed again from the reception element.
11. A dispensing device in accordance with claim 1 , wherein the reception element has a coding element for a correct positioning of the first and second storage containers of the multicomponent cartridge.
12. A dispensing device in accordance with claim 11 , wherein the coding element includes a first opening and a second opening in which a respective storage container of the multicomponent cartridge can be received, with a diameter of the first opening being different from a diameter of the second opening.
13. A dispensing device in accordance with claim 1 , wherein a movement of the plunger arrangement in the direction of a dispensing end of the multicomponent cartridge takes place by means of an actuation of a trigger lever arrangement of the drive arrangement.
14. A dispensing device in accordance with claim 1 , wherein the reception element has a latching element for latching the reception element in at least one of the dispensing position and the assembly position.
