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.

1. A beverage production device for producing a beverage from a single-use capsule containing a beverage ingredient, the beverage production device comprising: a brewing unit configured to receive the single-use capsule in a cavity defined by a first engaging member and a second engaging member that enclose and press the single-use capsule at a flange-like rim in a liquid seal-tight manner, the first engaging member having an internal recessed surface that extends inwardly to define an internal cavity for receiving at least a part of the single-use capsule, the first engaging member comprising an annular pressing portion for applying a sealing pressure on the flange-like rim, a water inlet and at least one piercing member provided at a bottom of the internal cavity of the first engaging member for injecting water in the single-use capsule, the first engaging member and second engaging member configured to be in closure at a nip to leak a liquid injected in the internal cavity when the single-use capsule is not present, and the annular pressing portion comprisingan outermost annular pressing edge comprising one or more leak passages, all of the one or more leak passages together in combination arearranged only within an angular path within less than 90 degrees on the outermost annular pressing edge, the outermost annular pressing edge not including any leak passage between 90 and 360 degrees, and the outermost annular pressing edge comprising a flat portion outside the angular path, the brewing unit oriented to close the first engaging member and the second engaging member with the one or more leak passages oriented along a horizontal axis to direct a water flow downward,an innermost pressing edge comprising a series of indentations forming liquid leak passages between each of the indentations, and an annular liquid collecting recess extending between the innermost pressing edge and the outermost annular pressing edge. 2. The beverage production device according to claim 1, wherein the outermost annular pressing edge comprises an additional series of indentations circumferentially distributed for delimiting passages therebetween. 3. The beverage production device according to claim 1, wherein the series of indentations of the innermost pressing edge are distributed along a whole circumference of the innermost pressing edge. 4. The beverage production device according to claim 1, wherein internal grooves are provided on a surface of the internal cavity of the first engaging member. 5. The beverage production device according to claim 4, wherein the second engaging member has a transversal surface forming a series of perforating elements suitable for perforating a delivery face of the single-use capsule. 6. The beverage production device according to claim 1, wherein the internal cavity is horizontal in the brewing unit and has a median horizontal plane, and all of the one or more leak passages are oriented below the median horizontal plane of the cavity. 7. The beverage production device according to claim 1, wherein all of the one or more leak passages extend longitudinally in an inner surface of the internal cavity. 8. The beverage production device according to claim 1, wherein the series of indentations of the innermost pressing edge are radially out of alignment with reference to indentations at the outermost annular pressing edge. 9. The beverage production device according to claim 1, wherein the series of indentations of the innermost pressing edge are distributed along an inner angular path greater than the angular path of the one or more leak passages together in combination. 10. The beverage production device according to claim 1, wherein the one or more leak passages is a plurality of leak passages that forms a series of leak passages, and the one or more leak passages extend from one end of the internal cavity in a direction toward an opposite end of the internal cavity. 11. The beverage production device according to claim 1, comprising a flow deflecting part positioned below the one or more leak passages and configured to direct the water flow from the one or more leak passages into an outlet assembly of the beverage production device when the first engaging member and the second engaging member enclose the single-use capsule. 12. The beverage production device according to claim 11, wherein the flow deflecting part is engaged with a rear opening of a cover of the outlet assembly and positioned to guide the water flow to a beverage outlet of the outlet assembly. 13. A system for the production of a beverage from a single-use capsule containing a beverage ingredient, the system comprising: the single-use capsule comprising the beverage ingredient and comprising a sealing flange-like rim; anda brewing unit configured to receive the single-use capsule therein upon closing of a first engaging member and a second engaging member that form a cavity for enclosing and pressing the single-use capsule at the sealing flange-like rim in a liquid seal-tight manner, the first engaging member having an internal recessed surface that extends inwardly to define an internal cavity for receiving at least a part of the single-use capsule, the first engaging member comprising an annular pressing portion for applying a sealing pressure on the sealing flange-like rim of the single-use capsule, a water inlet and at least one piercing member provided at a bottom of the internal cavity of the first engaging member for injecting water in the single-use capsule, the first engaging member and the second engaging member designed to be in closure at a nip to leak a liquid injected in the internal cavity when the single-use capsule is not present, and the annular pressing portion comprising an outermost annular pressing edge comprising one or more leak passages, all of the one or more leak passages together in combination arearranged only within an angular path within less than 90 degrees on the annular pressing edge, the annular pressing edge not including any leak passage between 90 and 360 degrees, and the annular pressing edge comprising a flat portion outside the angular path, and the brewing unit oriented to close the first engaging member and the second engaging member with the one or more leak passages oriented along a horizontal axis to direct a water flow downward,an innermost pressing edge comprising a series of indentations forming liquid leak passages between each of the indentations, and an annular liquid collecting recess extending between the innermost pressing edge and the outermost annular pressing edge. 14. The system according to claim 13, wherein the single-use capsule comprises a deformable sealing material at the sealing flange-like rim. 15. The system according to claim 14, wherein the added sealing member is a rubber-elastic or plastic material. 16. The system according to claim 13, wherein the single-use capsule comprises an added sealing member at the sealing flange-like rim.
