Abstract

A cartridge for flowable washing or cleaning agents for use in a dispenser includes at least two elements, each having a connecting edge by which the at least two elements are connected and bonded together to define an interior space; a plurality of chambers within the interior space for spatially separate accommodation of different preparations of a flowable washing or cleaning agent; a cartridge bottom surface which in a service position is directed downwards in the direction of gravity; and at least two chambers, each of which comprises at least one outlet orifice arranged on the cartridge bottom, wherein the connecting edge of the elements extends across the cartridge bottom surface at a distance from the outlet orifices such that the connecting edge does not intersect with or come into contact with the outlet orifices.

Claims

1. A cartridge (1) for flowable washing or cleaning agents for use in a dispenser (2), comprising:

at least two elements (6,7), each having a connecting edge by which the at least two elements (6,7) are connected and bonded together to define an interior space;

a plurality of chambers (3a, 3b, 3c) within the interior space for spatially separate accommodation of different preparations of a flowable washing or cleaning agent;

a cartridge bottom surface (4) which in a service position is directed downwards in the direction of gravity; and

at least two chambers (3a, 3b, 3c), each of which comprises at least one outlet orifice (5a, 5b, 5c) arranged on the cartridge bottom (4),

wherein the connecting edge (8) of the elements (6, 7) extends across the cartridge bottom surface (4) at a distance from the outlet orifices (5a, 5b, 5c) such that the connecting edge (8) does not intersect with or come into contact with the outlet orifices (5a, 5b, 5c).

2. The cartridge according to claim 1, wherein the chambers (3a, 3b, 3c) are arranged substantially next to one another and the outlet orifices (5a, 5b, 5c) are arranged in a line.

3. The cartridge according to claim 1, wherein the ratio of height:

width;

depth of the cartridge (1) is between 10;

10;

1 and 50;

50;

1.

4. The cartridge according to claim 1, wherein the cartridge (1) further comprises a top surface (10) and side surfaces (11, 12), and the connecting edge (8) extends along the top (10), bottom (4) and side surfaces (11, 12) of the cartridge (1).

5. The cartridge according to claim 1, wherein one element (6) is trough-shaped and the second element (7) is lid-like.

6. The cartridge according to claim 1, wherein both elements (6, 7) are trough-shaped.

7. The cartridge according to claim 1, wherein at least one cartridge element (6, 7) comprises at least one separating web (9a, 9b), which, in the assembled state of the elements (6, 7), separates two adjacent chambers (3a, 3b, 3c) of the cartridge (1) from one another.

8. The cartridge according to claim 1, wherein one of the cartridge elements (6) takes the form of a bottomless cellular container with the chambers (3a, 3b, 3c) and the second cartridge element takes the form of a cartridge bottom (4), which is connected in liquid-tight manner to the bottomless cellular container along the connecting edge (8) or the second element takes the form of a cartridge lid (10), which is connected in liquid-tight manner to the cellular container open at the top along the connecting edge (8).

9. The cartridge according to claim 1, wherein the cartridge (1) comprises an asymmetric three-dimensional shape such that coupling with the dispenser (2) is possible only when the cartridge (1) and the dispenser (2) are in a position intended therefor.

10. The cartridge according to claim 1, further comprising ventilation means positioned toward the top of the cartridge for ventilation of the cartridge chambers (3a, 3b, 3c) to ensure pressure equalization between the interior of the cartridge chambers (3a, 3b, 3c) and the surrounding environment as the filling level of the chambers (3a, 3b, 3c) declines.

11. The cartridge according to claim 10, wherein the ventilation means is a valve.

12. The cartridge according to claim 11, wherein the valve is a silicone valve.

13. The cartridge according to claim 10, wherein the ventilation means comprises microorifices in a cartridge wall.

14. The cartridge according to claim 1, further comprising at least one ventilation orifice at the bottom surface in the direction of gravity for the ventilation of at least one chamber, wherein the ventilation orifice is separate from the release orifice and the ventilation orifice is connected in communicating manner with at least one chamber of the cartridge via a ventilation channel in such a way that the end of the ventilation channel remote from the ventilation orifice opens, in a release position of the cartridge as coupled with the dispenser, above the maximum filling level of the cartridge.

15. The cartridge according to claim 14, wherein the ventilation channel is formed wholly or partially, in particular integrally, in or on the walls and/or webs of the cartridge.

16. The cartridge according to claim 1, further comprising one ventilation orifice and one release orifice for each of the chambers.

17. The cartridge according to claim 1, wherein each of the outlet orifices (5a, 5b, 5c) has a diameter of 0.7-1.0 times a width of the cartridge bottom (4).

18. A dispensing system (1, 2), in particular for a user to position in the interior of a dishwashing machine, comprising;

at least one cartridge (1), as set forth in claim 1; and

a dispenser (2) couplable with the cartridge (1) and comprising;

at least one energy source (15),

a control unit (16),

a sensor unit (17),

at least one actuator (18), which is connected with the energy source (15) and the control unit (16) in such a manner that a control signal from the control unit (16) brings about movement of the actuator (18),

a closing element (19), which is coupled with the actuator (18) such that movement of the actuator (18) displaces the closing element (19) into a closure or a release position, and

at least one dispensing chamber (20) which, when cartridge (1) and dispenser (2) are assembled, is connected in communicating manner with at least one of the cartridge chambers (3a, 3b, 3c), the dispensing chamber (20) comprising an inlet (21) for inflow of washing or cleaning agent from a cartridge chamber (3a, 3b, 3c) and an outlet (22) for outflow of washing or cleaning agent from the dispensing chamber (20) into the surrounding environment, at least the outlet (22) of the dispensing chamber (20) being closable or openable by the closing element (19).
