Abstract

The invention relates to a cartridge housing comprising a diluting means, especially a water supply, a mixing chamber in which the diluting means and a beverage and/or food substrate are mixed, and an outlet. The cartridge housing is fitted with a hollow rod such that the sealing film of the cartridge is pierced as soon as the cartridge is inserted into the cartridge housing, thereby creating the flow connection between the cartridge and a mixing chamber.

Claims

1. A cartridge receptacle having:

a) a diluent inflow;

b) a mixing chamber in which a diluent and a beverage substrate, a foodstuff substrate, or both the beverage substrate and the foodstuff substrate are mixed;

c) an outflow;

d) a piercing means which is configured to perforate a membrane of a cartridge;

wherein with regard to a direction of flow of the diluent, a flow cross section is first expanded and then reduced again;

wherein the piercing means is located within the direction of flow and between the diluent inflow and the outflow; and

wherein at least one mixing element is provided in the mixing chamber.

2. The cartridge receptacle according to claim 1, wherein the diluent is water.

3. The cartridge receptacle according to claim 1, wherein the mixing chamber has a protuberance.

4. The cartridge receptacle according to claim 3, wherein the outflow is provided in the protuberance.

5. The cartridge receptacle according to claim 1, wherein the cartridge receptacle has a fastening ring, a securing ring, or both the fastening ring and the securing ring.

6. The cartridge receptacle according to claim 5, wherein the fastening ring, the securing ring, or both the fastening ring and the securing ring are provided with a predetermined breaking point, a predetermined deformation point, or both the predetermined breaking point and the predetermined deformation point at the mixing chamber.

7. The cartridge receptacle according to claim 1, wherein the cartridge receptacle has a spike guide and the piercing means is mounted in a displaceable manner within the spike guide;

and

wherein the piercing means is displaceable between a retracted position, in which the piercing means is away from the membrane, and an extended position, in which the piercing means pierces the membrane of the cartridge and projects into the cartridge.

8. The cartridge receptacle according to claim 7, wherein at least one lateral channel for conveying the beverage substrate, the foodstuff substrate, or both the beverage substrate and the foodstuff substrate in a direction of the mixing chamber when the membrane is pierced by the piercing means has been introduced into an outer wall of the piercing means.

9. The cartridge receptacle according to claim 8, wherein a compressed-air line is integrated into the piercing means, and wherein a compressed-air connection of the compressed-air line for connecting to a compressed-air source is formed on a side of the piercing means that is remote from the cartridge, said compressed-air connection being accessible in particular from outside the cartridge receptacle, and wherein a compressed-air outlet of the compressed-air line configured to blow compressed air into the cartridge is formed on a side of the piercing means that faces the cartridge.

10. A system having the cartridge receptacle according to claim 1, wherein the cartridge is provided,

wherein the cartridge has a wall region, one end of which is adjoined by a connecting region which is closed by the membrane, and at an opposite end of which optionally a bottom region is provided;

and

wherein the wall region, and optionally the bottom region, define a cavity which accommodates the beverage substrate, the foodstuff substrate, or both the beverage substrate and the foodstuff substrate.

11. The system according to claim 10, wherein the connecting region has a flange which is provided with a positioning means, a covering means, or both the positioning means and the covering means.

12. The system according to claim 11, wherein the positioning means, the covering means, or both the positioning means and the covering means is an indentation, a protuberance, or both the indentation and the protuberance which protrudes from the flange.

13. The system according to claim 12, wherein the indentation, the protuberance, or both the indentation and the protuberance protrudes from a circumference of the flange.

14. The system according to claim 11, wherein the membrane is provided on the flange.

15. The system according to claim 11, wherein the flange cooperates in a sealing manner with the cartridge receptacle.

16. The system according to claim 10, wherein a neck is provided between the wall region and the connecting region.

17. The system according to claim 10, wherein the cartridge receptacle is provided in the connecting region of the cartridge.

18. The system according to claim 10, wherein the cartridge and the cartridge receptacle are connected together in a rotationally fixed manner.

19. The system according to claim 10, wherein a covering means covers the outflow of the cartridge receptacle.
