Beverage machine cartridge holder
A method and apparatus for opening and closing a cartridge holder of a beverage forming machine. The cartridge holder may have an opening arranged to receive and hold a cartridge with the cartridge holder. The opening may be adjustable in size and/or shape to allow the cartridge holder to receive and engage with cartridges of different size and/or shape. The cartridge holder may include one or more movable portions that are adjustable in position to effectively adjust a size and/or shape of the opening.
1. A beverage forming apparatus, comprising:
a frame arranged to support components of the beverage forming apparatus;
a cartridge holder including a cartridge engagement portion that defines an opening and that is arranged to engage with a cartridge placed in the opening and support a weight of the cartridge, the cartridge having a rim, and the engagement portion including one or more compliant sections that are arranged to contact regions of first and second cartridges at the rim of the cartridge, the regions at the rim of the first and second cartridges being differently sized and/or shaped relative to each other, and the one or more compliant sections being movable relative to the cartridge holder to adjust a size and/or shape of the opening to accommodate and engage with the differently sized and/or shaped regions at the rims of the first and second cartridges;
a cover arranged to cooperate with the cartridge holder to at least partially enclose a cartridge held by the cartridge holder for formation of a beverage using the cartridge; and
a liquid supply system at least partially supported by the frame arranged to provide a liquid for combination with a beverage medium in a cartridge held by the cartridge holder to form a beverage.
2. The apparatus of claim 1 , wherein the one or more compliant sections each include a resilient element that deforms in response to insertion of the first or second cartridge into the opening of the cartridge holder.
3. The apparatus of claim 1 , wherein the one or more compliant sections includes a plurality of wall sections that are movable relative to each other to accommodate the first or second cartridge.
4. The apparatus of claim 1 , wherein the one or more compliant sections includes at least one trigger that is mounted for sliding movement away from the opening.
5. The apparatus of claim 4 , wherein the trigger is movable to receive a spout of the first or second cartridge.
6. The apparatus of claim 1 , wherein the cartridge engagement portion engages with a rim of the first and second cartridge to support a weight of the cartridge, and wherein the first cartridge has a rim with a first diameter, and the second cartridge has a rim with a second diameter that is smaller than the first diameter.
7. The apparatus of claim 1 , wherein the rim of the second cartridge is circular, and the rim of the first cartridge has a circular portion and a spout portion that extends outwardly from the circular portion.
8. The apparatus of claim 1 , wherein the one or more compliant sections includes a plurality of wall portions that extend upwardly from a bottom of the engagement portion, where the wall portions are joined together, to a top of the engagement portion, the wall portions located at the top of the engagement portion being radially movable relative to each other and arranged for engagement with the first and second cartridge.
9. The apparatus of claim 8 , wherein the wall portions are radially movable based on flexing movement of the wall portions relative to the bottom of the engagement portion.
10. The apparatus of claim 1 , wherein the cover includes a liquid inlet to introduce liquid from the liquid supply system to a cartridge held in the cartridge holder.
11. The apparatus of claim 10 , wherein the cover includes a first beverage outlet to receive beverage exiting a cartridge held in the cartridge holder.
12. The apparatus of claim 11 , further comprising a second beverage outlet mounted to the cartridge holder and arranged to receive beverage exiting a cartridge held in the cartridge holder.
13. The apparatus of claim 12 , wherein the second beverage outlet is selectively movable into and out of a cartridge receiving area of the cartridge holder based on whether the first or second cartridge is received in the cartridge holder.
14. The apparatus of claim 13 , wherein the liquid inlet and the first and second beverage outlets each include a piercing element to pierce a cartridge.
15. The apparatus of claim 14 , wherein the piercing elements of the liquid inlet and the first beverage outlet face downwardly and the second beverage outlet faces upwardly with the cover cooperating with the cartridge holder to at least partially enclose a cartridge.
16. The apparatus of claim 1 , wherein regions of the first and second cartridges where the engagement portion engages with the first and second cartridges have different shapes.
17. The apparatus of claim 1 , wherein regions of the first and second cartridges where the engagement portion engages with the first and second cartridges have different sizes.
