Embodiment Construction

[0043] figure 1 and figure 2 A partial view of a beverage production plant is shown. For simplicity, only the brewing unit 1 of the entire device is shown. However, such units are integrated or incorporated into more complex appliances such as coffee machines, which include additional components, notably water supply such as pumps, means for delivering water, heaters, electronic control boards , drip trays, capsule trays, etc.

[0044] In this specification, the term "beverage production system" is used to define the combination of a beverage production device and a capsule suitable for brewing in the device.

[0045] In usual manner, the brewing unit 1 comprises a frame 2 and a beverage outlet assembly 3 forming a flow guide for the beverage. The flow outlet assembly comprises a housing cover 4 terminating in a downwardly directed outlet 5 .

[0046] The brewing unit is arranged to receive a single use capsule 8 containing beverage ingredients to be brewed. The term "c...

Abstract

Beverage production device for producing a beverage from a single-use capsule containing a beverage ingredient, comprising : a brewing unit for receiving the capsule therein upon relative closing of a first and second engaging members forming a cavity for encasing the capsule and pressing it at a flange-like rim in a liquid seal-tight manner, wherein at least one of the first and second engaging members comprises a substantially annular pressing portion for applying a sealing pressure on the flange-like rim of the capsule, the first and second engaging members being configured in relative closure at the nip to leak to a liquid injected in the cavity when a capsule is not present, wherein one of at least the first or second engaging members comprises, at its annular pressing portion, flow directing means comprising at least one passage arranged for controlling liquid leakage only within a limited angular radial direction when the first and second engaging members are closed at the nip.

Description

technical field [0001] The present invention relates to the production of a beverage from a device adapted to receive a single-use capsule containing a beverage substance. Background technique [0002] The background field of the invention is beverage production systems using capsules containing beverage or other food (eg soup) ingredients / ingredients. By means of the interaction of these ingredients with the liquid, beverages such as coffee or tea can be produced. Said interaction may eg be a brewing (eg extraction) or a dissolution process. Such a capsule is particularly suitable for containing ground coffee for the production of a coffee beverage by entering hot water under pressure into the capsule and expelling the coffee beverage from the capsule. [0003] A system and method for obtaining a beverage from a capsule containing a substance is eg known from EP-A-512470. [0004] Patent application EP 1 654 966 proposes an improvement for providing a better seal when th...
