  • this projecting annular formation is intended to abut against a corresponding shoulder provided in the infusion chamber of a machine used for the preparation of a beverage in order to provide a liquid-tight separation between the portion of the cartridge through which pressurised water is introduced and the portion through which the beverage leaves the cartridge.
  • One object of this invention is to provide a cartridge of the type initially defined configured in such a way that it can also be used in a machine for the preparation of beverages which is designed for the use of another (and different) type of cartridge, in particular a machine of the type described in Italian patent application TO2012A000061 in the name of the Applicant.

  • This invention is intended to provide a cartridge which in addition to functioning in a machine provided with a cartridge holder specifically designed and manufactured for it is capable of being used effectively in a machine which has a cartridge holder of a different type belonging to the prior art. This is in order to offer the consumer, or the owner of such a machine according to the prior art, the possibility of widening the range of cartridges which can be used and the food products which can be produced, for example by making it possible to produce coffee of the “filter coffee” or extracts from “leaf” products in addition to coffee of the “espresso” type.
  • Another object of this invention is to provide a cartridge which can be conveniently made using a biodegradable/compostable material as defined below in this description.
