Abstract

The invention concerns beverage production system comprising a capsule ( 10 ) and a module ( 1 ) for producing a beverage from the capsule, the capsule ( 10 ) comprising an enclosure ( 10 a ) and a rim ( 10 b ), and the module ( 2 ) comprising a first capsule engagement member ( 3 ), which can be displaced relative to a second, co-operating capsule engagement member ( 2 d ) between a capsule discharge position and a beverage production position, and the displaceable first capsule engagement member ( 3 ) comprises holding means configured for holding the capsule within, the module comprising at least two means ( 7, 7 a, 7 b ) for engaging the rim of the capsule extending beyond the first capsule engagement member when the first capsule engagement member ( 3 ) is displaced from the beverage production position to its capsule discharge position, and wherein the holding means are discrete hooks ( 341, 342 ) configured to engage with the rim ( 10 b ) of the capsule, and the retaining means are configured so that, during the displacement of the first capsule engagement member ( 3 ) from the beverage production position to its capsule discharge position, one ( 7 b ) of the two engaging means engages the rim of the capsule before the other engaging mean ( 7 a ).

First claim

1 . A beverage production system comprising a capsule and a module for producing a beverage from the capsule,
the capsule comprising an enclosure and a rim, and the module comprising: a first capsule engagement member, which can be displaced relative to a second, co-operating capsule engagement member between a capsule discharge position and a beverage production position, a retractor for actively retracting the first capsule engagement member from the beverage production position to the capsule discharge position in which the capsule is discharged from the first capsule engagement member, the displaceable first capsule engagement member comprising a capsule receptacle, and the capsule presenting: an enclosure outer shape that is conformal to at least a portion of the capsule receptacle, and a rim size such that at least a part of the rim of the capsule extends beyond at least a part of the first capsule engagement member once it is engaged in the first capsule engagement member, and the displaceable first capsule engagement member comprising a holder configured for holding the capsule within the capsule receptacle, the module comprising at least two retainers for retaining the rim of the capsule extending beyond the first capsule engagement member when the first capsule engagement member is displaced from the beverage production position to its capsule discharge position, wherein the holder comprises discrete hooks configured to engage with the rim of the capsule, and wherein the two retainers are configured so that, during the displacement of the first capsule engagement member from the beverage production position to its capsule discharge position, one of the two retainers engages the rim of the capsule before the other retainer.

2 . A beverage production system according to claim 1 , wherein:
one retainer is positioned on each lateral side of the longitudinal axis of displacement of the first capsule engagement member, and the positions of the two retainers along the longitudinal axis of displacement are offset one relative to the other.

3 . A beverage production system according to claim 2 , wherein the positions of the two retainers along the longitudinal axis of the frame of the module are offset one relative to the other by at least 1 mm.

4 . A beverage production system according to claim 1 , wherein:
the module comprises lateral walls on each lateral side of the path of the first capsule engagement member, and the at least two retainers are tabs protruding from the lateral walls.

5 . A beverage production system according to claim 1 , wherein the displaceable first capsule engagement member comprises two hooks configured to engage with the rim of the capsule, the hooks being positioned on the lateral sides of the front face of the capsule receptacle.

6 . A beverage production system according to claim 1 , wherein the hooks and the first capsule engagement member are made of the same plastic material and are molded as one single piece with that member.

7 . A beverage production system according to claim 1 , wherein each hook comprises an arm extending from a lateral side of the front face of the capsule receptacle, the arm presenting a slanted end and comprising a vertical slit.

8 . A beverage production system according to claim 1 , wherein tabs are positioned in the lateral walls of the module so as to engage a part of the rim of the capsule, the part being close to the portion of the rim engaged with one of the hooks.

9 . A beverage production system according to claim 1 wherein the retractor is designed to implement the combination of a horizontal linear movement and an upwardly swivelling end movement.

10 . A beverage production system according to claim 1 wherein the first capsule engagement member comprises an opener for piercing the capsule and injecting water in the capsule.

11 . A beverage production system according to claim 1 wherein the module comprises an opener for piercing the capsule and producing a beverage outlet in the capsule.

12 . A beverage production system according to claim 1 wherein the module comprises pre-fixation members which are designed to engage with the rim of the capsule for fixation of the capsule close to the second engagement member.

13 . A method for producing a beverage from a capsule comprising an enclosure and a rim in a beverage production system comprising a capsule and a module for producing a beverage from the capsule, the capsule comprising an enclosure and a rim, and the module comprising: a first capsule engagement member, which can be displaced relative to a second, co-operating capsule engagement member between a capsule discharge position and a beverage production position, a retractor for actively retracting the first capsule engagement member from the beverage production position to the capsule discharge position in which the capsule is discharged from the first capsule engagement member, the displaceable first capsule engagement member comprising a capsule receptacle, and the capsule presenting: an enclosure outer shape that is conformal to at least a portion of the capsule receptacle, and a rim size such that at least a part of the rim of the capsule extends beyond at least a part of the first capsule engagement member once it is engaged in the first capsule engagement member, and the displaceable first capsule engagement member comprising a holder configured for holding the capsule within the capsule receptacle, the module comprising at least two retainers for retaining the rim of the capsule extending beyond the first capsule engagement member when the first capsule engagement member is displaced from the beverage production position to its capsule discharge position, wherein the holder comprises discrete hooks configured to engage with the rim of the capsule, and wherein the two retainers are configured so that, during the displacement of the first capsule engagement member from the beverage production position to its capsule discharge position, one of the two retainers engages the rim of the capsule before the other retainer, wherein:
the hooks engage with the rim of the capsule, when the first capsule engagement member is displaced to the second, co-operating capsule engagement member, and
the two retainers of the module retain the rim of the capsule successively one after the other during the displacement of the first capsule engagement member from the beverage production position to its capsule discharge position.
