Abstract

A machine ( 1 ) for serving a beverage ( 7 ) via a dispensing outlet ( 8 ) to a consumer receptacle ( 9 ) by mixing water ( 3 ) from a water source ( 3 ′) with a flavouring ingredient ( 2 ), has a mixing unit ( 10 ) that comprises: a stationary support ( 11 ); a seat ( 12 ) having an ingredient opening ( 120 ); a closure part ( 13 ) configured to close and open the ingredient opening ( 120 ); and a wall part ( 14 ) that is movable inside the seat ( 12 ). The seat ( 12 ), the closure part ( 13 ) and the wall part ( 14 ) are: mounted to the support ( 11 ); and relatively movable between a transfer configuration and a mixing chamber configuration in which the seat ( 12 ) and the closure part ( 13 ) and the wall part ( 14 ) form a mixing chamber ( 12 ′) fluidically connected with the water source ( 3 ′). The seat ( 12 ) is configured to move relatively to the support ( 11 ) according to simultaneous and/or successive geometric translation and geometric rotation.

First claim

1 . A machine for handling a flavouring ingredient and preparing a beverage therefrom and serving said beverage via a dispensing outlet to a consumer receptacle including a mixing unit that comprises:
a support, such as a frame and/or housing, that is stationary during said handling of said flavouring ingredient ; configured to receive said flavouring ingredient unwrapped before mixing with said water; a closure part configured to close and open the ingredient opening; a wall part that is movable inside the seat, the seat, the closure part and the wall part being:
directly or indirectly mounted to the support, and
relatively movable between: a transfer configuration for supplying said flavouring ingredient into the seat and removing such ingredient upon beverage preparation; and a mixing chamber configuration in which the seat and the closure part and the wall part form a mixing chamber fluidically connected with the water source,
during beverage preparation, said flavouring ingredient being mixed with said water in the mixing chamber to form said beverage prior to serving thereof via the dispensing outlet,
the seat is configured to move relatively to the support according to simultaneous and successive geometric translation and geometric rotation.

2 . The machine of claim 1 , wherein the seat is arranged to move relatively to the support:
by geometric translation without rotation into and out of the mixing chamber configuration and/or into and out of the transfer configuration; and by simultaneous geometric translation and geometric rotation into and out of the transfer configuration.

3 . The machine of claim 1 , wherein the seat has a first pivot and a second pivot spaced apart from the first pivot, the seat being configured such that, to move from the mixing chamber configuration to the transfer configuration:
in a first step, the first and second pivots move relatively to the support along a single straight direction or along parallel directions to move out of the mixing chamber configuration; and then in a second step, the first and second pivots move simultaneously along first and second directions, respectively, whereby either the first and the second directions are at an angle, or the first and the second directions are parallel and the first and second pivots move at different respective speeds, such that the first and second pivots and the seat all simultaneously translate and rotate, thereby the first and second pivots having reached the transfer configuration or an intermediate configuration from which, in a third step, the first and second pivots and the seat are translated without rotation into the transfer configuration.

4 . The machine of claim 1 , wherein the mixing unit comprises said wall part actuator that is connected to the wall part by a wall part transmission.

5 . The machine of claim 1 , wherein the support and the seat are connected by a guide-rail arrangement.

6 . The machine of claim 1 , wherein the mixing unit comprises a waste ingredient remover configured to remove a waste ingredient from the ingredient opening.

7 . The machine of claim 1 , wherein the mixing unit comprises a closure seal which is located between the closure part and the seat when closed by the seat.

8 . The machine of claim 1 , wherein the closure part comprises a peripheral sealing member displaceably mounted on a closure holder and urged away from the holder against the seat.

9 . The machine of claim 1 , wherein,
after an introduction into the seat’s ingredient opening in the transfer configuration of at least one solid portion of a self-supporting agglomerate of said flavouring ingredient and subsequent relative movement from the transfer configuration into the mixing chamber configuration and prior to serving said beverage via the dispensing outlet, said control unit is configured to control a preconditioning of the flavouring ingredient by:
a portion break-up relative movement of the seat and the closure part and the wall part ; and
a portion loosening supply of water from a or said water source into the mixing chamber.

10 . The machine of claim 9 , wherein the control unit is configured to control via said at least one actuator said break-up relative movement between the wall part and the closure part so as to exercise a compression force onto the solid portion(s) between the closure and wall parts to break-up the solid portion(s).

11 . The machine of claim 9 , wherein the control unit, to control the preconditioning of the flavouring ingredient, controls said liquid driver.

12 . A combination of a machine for handling a flavouring ingredient and preparing a beverage therefrom and serving said beverage via a dispensing outlet to a consumer receptacle including a mixing unit that comprises:
a support, such as a frame and/or housing, that is stationary during said handling of said flavouring ingredient; a seat configured to receive said flavouring ingredient unwrapped before mixing with said water; a closure part configured to close and open the ingredient opening; a wall part that is movable inside the seat, the seat, the closure part and the wall part being:
directly or indirectly mounted to the support; and
relatively movable between: a transfer configuration for supplying said flavouring ingredient into the seat and removing such ingredient upon beverage preparation; and a mixing chamber configuration in which the seat and the closure part and the wall part form a mixing chamber fluidically connected with the water source,
during beverage preparation, said flavouring ingredient being mixed with said water in the mixing chamber to form said beverage prior to serving thereof via the dispensing outlet, the seat is configured to move relatively to the support according to simultaneous and successive geometric translation and geometric rotation and a flavouring ingredient for preparing said beverage in the machine.
