Abstract
Beverage production device for producing a beverage from a single-use capsule containing a beverage ingredient, comprising: a brewing unit that receives the capsule in a cavity defined by first and second engaging members that enclose the capsule and press it at a flange-like rim in a liquid seal-tight manner. 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. One of at least the first or second engaging members comprises, at its annular pressing portion, 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.
