Capsule for the preparation of beverages

Abstract

This disclosure relates to a capsule (1) for making a beverage, containing a powdered food substance (8) which enables a beverage to be made by passing water through it. The capsule (1) comprises a cup-shaped containment body (2), in turn comprising a tubular lateral wall (21) and a bottom portion (22), and a closing element (29) that closes the top of the containment body (2). The bottom portion(22) has a dispensing hole (26) and the containment body (2) defines a containment chamber (20) inside itself. A filtering element (3) is mounted in the containment chamber (20) and is positioned between the powdered food substance (8) and the bottom portion (22). A dispensing element (5) is mounted in the containment chamber (20) and is positioned between the filtering element (3) and the bottomportion (22). The dispensing element (5) is intended to create a tortuous path for the beverage that flows towards the dispensing hole (26). A barrier impermeable to oxygen (6) is mounted in the containment chamber (20) and is interposed between the filtering element (3) and the dispensing element (5). The barrier impermeable to oxygen (6) is a sheet of flexible material fixed in an oxygen-tight way to the containment body (2) and intended to be torn during use, thereby allowing the beverage to pass through it. A flow throttling element (7) is mounted in the containment chamber (20) in a position interposed between the filtering element (3) and the dispensing element (5) and obstructs the passage cross-section for the beverage in the containment chamber (20). The flow throttling element (7) has at least one through opening (71) through which, in use, the beverage flows towards the dispensing element (5).

Description

technical field [0001] The present invention relates to a type of capsule for making a beverage, which capsule contains a powdered food substance through which the beverage can be made by passing hot water. The food substance may be soluble or of a type that can be extracted by infusion, eg roasted ground coffee. Background technique [0002] In particular, the present invention relates to capsules of the type described in patents EP 1 472 156 , EP 1 500 358 , EP 1 574 452 and EP 1 808 382 . That is, when the capsule is used in a suitable beverage making machine, the capsule is capable of dispensing the beverage directly into the cup below. The capsule comprises a cup-shaped containment body with a bottom equipped with a dispensing hole. The containment body is closed at the top by a closure element and inside it, has at least one lower filter element between the powdered food substance and the bottom. [0003] For this type of capsule, the capsule is usually made in such...

AI Technical Summary

Problems solved by technology

This problem is even greater for capsules that dispense directly into the cup, since there is no dispenser on the outside of the capsule suitable for regularizing the flow of the drink

[0006] Also, at the end of the beverage dispensing there may be considerable drips from the capsule as the powdered food substance releases the water it absorbed during the beverage making step

This is inconvenient since the drops stain the underlying surface after the cup is removed and the user also has to dispose of the dropped capsule
