Cartridge housing for a beverage or food cartridge
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.
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; and
d) a fastening ring, a securing ring, or both the fastening ring and the securing ring, wherein the fastening ring, the securing ring, or both is provided with a predetermined breaking point, a predetermined deformation point, or both the predetermined breaking point and the predetermined deformation point which connect the fastening ring, the securing ring, or both to 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 with regard to a direction of flow of the diluent, a flow cross-section is first expanded and then reduced again.
4. The cartridge receptacle according to claim 1 , wherein the mixing chamber has a protuberance.
5. The cartridge receptacle according to claim 4 , wherein the outflow is provided in the protuberance.
6. The cartridge receptacle according to claim 1 , wherein at least one mixing element is provided in the mixing chamber.
7. The cartridge receptacle according to claim 1 , wherein the cartridge receptacle has a piercing means which is configured to perforate a membrane of a cartridge.
8. The cartridge receptacle according to claim 7 , wherein the cartridge receptacle has a spike guide, and wherein 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.
9. The cartridge receptacle according to claim 8 , wherein at least one lateral channel is introduced into an outer wall of the piercing means when the membrane is pierced by the piercing means; and
wherein the at least one lateral channel conveys the beverage substrate, the foodstuff substrate, or both the beverage substrate and the foodstuff substrate in a direction of the mixing chamber.
10. The cartridge receptacle according to claim 9 , wherein a compressed-air line is integrated into the piercing means;
wherein a compressed-air connection of the compressed-air line adapted to connect to a compressed-air source is formed on a side of the piercing means that is remote from the cartridge;
wherein the compressed-air connection is accessible from outside the cartridge receptacle; and
wherein a compressed-air outlet of the compressed-air line for blowing a compressed air into the cartridge is formed on a side of the piercing means that faces the cartridge.
11. The cartridge receptacle according to claim 1 wherein the diluent inflow and the outflow are provided at opposite ends of the cartridge receptacle.
12. The cartridge receptacle according to claim 7 , wherein the piercing means is located within a direction of flow and between the diluent inflow and the outflow.
13. A system having the cartridge receptacle according to claim 1 , wherein the system includes a cartridge;
wherein the cartridge has a wall region, one end of which is adjoined by a connecting region which is closed by a membrane; and
wherein the wall region defines a cavity which accommodates the beverage substrate, and/or the foodstuff substrate, or both the beverage substrate and the foodstuff substrate.
14. The system of claim 13 , wherein the cartridge includes a bottom region which together with the wall region defines the cavity.
15. The system according to claim 13 , 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.
16. The system according to claim 15 , 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.
17. The system according to claim 16 , wherein the indentation, the protuberance, or both the indentation and the protuberance protrudes from a circumference of the flange.
18. The system according to claim 13 , wherein a neck is provided between the wall region and the connecting region.
