Capsule for preparing coffee in a device comprising a cartridge holder with relief and recessed elements
First Claim
1. A capsule for the production of a beverage by extraction in a beverage production machine comprising a capsule holder with relief and recessed elements, the capsule comprising:
- an inverted cup-shaped body forming a chamber containing beverage forming ingredients;
a bottom injection wall;
a sidewall; and
a delivery wall which is sealed to the body and which comprises at least one calibrated orifice provides a restriction that does not expand by more than 500% of its initial diameter as a result of the process of extraction,wherein when the capsule is placed in a beverage production machine in a capsule holder having relief and recessed elements, the beverage delivery wall is not tearable against the capsule holder relief and recessed elements during extraction but instead the restriction created by the calibrated orifice provides a certain back pressure which generates an elevated pressure in the capsule during extraction that generates an intimate interaction between the beverage forming ingredients in the capsule and injected water, as well as a consistent flow of the beverage delivered from the capsule.

Abstract
A capsule for the production of a beverage in a beverage production machine comprising a capsule holder with relief and recessed elements. The capsule includes an inverted cup-shaped body forming a chamber containing beverage ingredients; a bottom injection wall; a sidewall; and a delivery wall which is sealed to the body. The delivery wall is configured and dimensioned to include a calibrated orifice or perforating means to provide a calibrated orifice with the beverage delivery wall not being tearable against the capsule holder during extraction. The wall also provides through the restriction created by the calibrated orifice a certain back pressure which generates an elevated pressure in the capsule during extraction. Also, a system and method for producing a beverage from the capsules of the invention.
