Description

technical field

[0001] The invention relates to a device for preparing a liquid beverage from a cartridge. The invention relates in particular to the preparation of hot or cold drinks from a cartridge containing one or more food ingredients. Background technique

[0002] There are various types of systems for preparing beverages from cartridges. It is preferably desirable to insert the cartridge into the machine in a rather straightforward and uncomplicated manner, and to allow easy removal of the cartridge after use.

[0003] A problem with some systems comprising cartridge support means incorporated in the machine lies in the fact that it is difficult to prevent any contact between the beverage and the machine. These systems are not suitable for multi-beverage use due to the frequent contact between the beverage and the cartridge support. This creates cross-contamination issues and hygiene issues, especially in the case of certain ingredients such as milk.
