AI Technical Summary

Technical Problem

Existing dosing systems for dishwashers face challenges in easily and safely exchanging containers due to manufacturing tolerances, which can lead to misalignment of connection pieces and potential leaks.

Method used

The container housing features material recesses between connection pieces, allowing for elastic deformation and compensating for manufacturing tolerances, thereby reducing the force required for connection and maintaining a secure seal.

Benefits of technology

This design enables easy and safe container exchange with reduced force requirements, preventing leaks and allowing for the use of less material, which lowers costs and environmental impact.

Abstract

The invention relates to a container (40) for a dosing system (1) with a dosing device (10) that can be positioned in an interior of a dishwasher, wherein the container (40) comprises a container housing having a first chamber (41) and at least one second chamber (42) in which preparations are stored, wherein a first connecting piece (44) is assigned to the first chamber (41) and a second connecting piece (45) to the second chamber (42), wherein the first connecting piece (44) can be connected to a first connection receptacle (20) of the dosing device (10) and the second connecting piece (45) can be connected to a second connection receptacle (21) of the dosing device (10), and wherein the first connecting piece (44) and the second connecting piece (45) are attached to the container housing.The invention is characterized in that at least one material recess (53) is provided on the container housing between the first connecting piece (44) and the second connecting piece (45), which weakens the dimensional stability of the container housing, so that a deformation of the container housing, which results in a change of a distance (47) between the first connecting piece (44) and the second connecting piece (45), is possible with a lower force.

Claims

1. A container (40) for a dosing system (1) with a dosing device (10) that can be positioned in the interior of a dishwasher, wherein the container (40) comprises a container housing having a first chamber (41) and at least one second chamber (42), in each of which preparations are stored, wherein a first connecting piece (44) is assigned to the first chamber (41) and a second connecting piece (45) is assigned to the second chamber (42), wherein the first connecting piece (44) can be connected to a first connection receptacle (20) of the dosing device (10) and the second connecting piece (45) can be connected to a second connection receptacle (21) of the dosing device (10), and wherein the first connecting piece (44) and the second connecting piece (45) are fastened to the container housing, characterized in thatat least one material recess (53) is provided on the container housing between the first connecting piece (44) and the second connecting piece (45), by means of which the dimensional stability of the container housing is weakened, so that a deformation of the container housing, which results in a change in a distance (47) between the first connecting piece (44) and the second connecting piece (45), is possible with a lower force.

2. Container (40) according to claim 1, characterized in that the container housing has a first housing half (49) and a second housing half (50) which are connected to one another at a circumferential edge (51).

3. Container (40) according to claim 2, characterized in that the first connecting piece (44) and the second connecting piece (45) are fastened to the peripheral edge (51) and the material recess (53) is provided on an edge section (51a) of the peripheral edge (51) between the first connecting piece (44) and the second connecting piece (45).

4. Container (40) according to claim 3, characterized in that the material recess (53) is formed by a slot which extends vertically inwards from an outer edge (54) of the edge portion (51a).

5. Container (40) according to claim 4, characterized in that the slot has parallel side edges and a rounded slot end.

6. Container (40) according to one of claims 1 to 5, characterized in that the container housing has a third chamber (43) to which a third connecting piece (46) is assigned, which can be connected to a third connection receptacle (22) of the dosing device (10).

7. Container (40) according to claim 6, characterized in that a further material recess (55) is provided between the second connecting piece (45) and the third connecting piece (46).

8. Container (40) according to claim 6 or 7, characterized in thatthe first connecting piece (44), the second connecting piece (45) and the third connecting piece (46) lie on a straight line.

9. Container (40) according to one of claims 1 to 8, characterized in that the first connecting piece (44) has a base body (56) with a weld-in part (57) which is sealingly attached to the container housing (40) and forms an inflow channel (59) which is connected to the first chamber (41).

10. Container (40) according to claim 9, characterized in that the base body (56) has a plug-in part (58) with a drainage channel (60), wherein the plug-in part (58) can be inserted into the first connection receptacle (20) of the dosing device (10).

11. Container (40) according to claim 10, characterized in that the inflow channel (59) and the outflow channel (60) are separated from each other by a closed membrane (62) in a new state.

12. Container (40) according to one of claims 9 to 11, characterized in thata finger ring (66) is fastened to the base body (56), which is movable from an initial position into an active position, wherein in the active position the finger ring (66) is designed to be able to be gripped behind by a human finger in order to introduce a force into the base body (56) by means of which the first connecting piece (44) can be separated from the first connecting receptacle (20).

13. Container (40) according to one of claims 12, characterized in that the finger ring (66) in the starting position surrounds a pressure plate (65) and lies essentially in the same plane as the pressure plate (65).

14. Container (40) according to claim 13, characterized in that the pressure plate (65) is slightly curved inwards and serves as a support for a human finger, by the force of which the first connecting piece (44) can be connected to the first connecting receptacle (20).
