Abstract

A capsule has an inlet face C formed by a circular section and a bulge section extending from the circular section so that the inlet face C is not symmetric in rotation. The capsule further has an optically readable code on a side wall of a cup-shaped body of the capsule opposite the bulge section. A beverage production machine has a capsule holder for holding the capsule in the beverage production machine so that the optically readable code can be read by a code reader. Liquid can be supplied to the capsule to produce a nutritional product. The optically readable code and the code reader can be prevented from being contaminated with liquid, vapor, dirt or the like. The beverage production machine can perform an automatic detection of the capsule type and a corresponding automatic setting of preparation parameters.

Claims

1. A beverage production machine for the preparation of a nutritional product, the machine comprising:

a housing;

a reservoir for holding a liquid,

a capsule holder removably insertable in the housing for holding a capsule containing nutritional ingredients;

a liquid injection assembly provided in the housing for supplying liquid held in the reservoir to a capsule held in the capsule holder; and

,

an optical code reading assembly of the beverage production machine for reading an optically readable code, wherein the capsule holder is interposed, when inserted in the housing, between the liquid injection assembly and the code reading assembly.

2. The beverage production machine of claim 1, wherein the optical code reading assembly comprises a code reader provided on a frame of the beverage production machine for reading an optically readable code, wherein the frame is located outside of the housing.

3. The beverage production machine of claim 2, wherein the housing comprises a window positioned between the inserted capsule holder and the code reader;

and the window is transparent to light emitted from the code reader.

4. The beverage production machine of claim 3, wherein the capsule holder comprises an aperture for uncovering an optically readable code of the capsule;

the aperture being aligned with the window in the housing.

5. The beverage production machine of claim 3, wherein the window is oriented along a plane which forms an angle in a range of 110°

and 160°

relative to the bottom plane of the capsule in the inserted capsule holder.

6. The beverage production machine of claim 1, wherein the liquid injection assembly comprises an injection plate adapted to open and close an opening of the housing to the capsule;

and a liquid needle adapted to be extended through the opening and to inject liquid into a capsule.

7. A beverage production machine for the preparation of a nutritional product from capsules containing nutritional ingredients, the machine comprising:

a housing;

a reservoir for holding a liquid;

a capsule holder removably insertable in the housing for holding a capsule containing nutritional ingredients;

a liquid injection assembly provided in the housing for supplying liquid held in the reservoir to a capsule held in the capsule holder; and

an optical code reading assembly comprising;

a code reader for reading an optically readable code on each capsule placed in the capsule holder when the capsule holder is inserted in the housing, and

a control unit including a memory for memorizing the last optically readable codes read by the code reader;

the control unit is adapted to deactivate the beverage production machine and/or to provide a warning signal to the user of the beverage production machine when an optically readable code read by the code reader corresponds to one of the last memorized optical codes, and the control unit is adapted to set at least one preparation parameter, for the nutritional product, according to the optically readable code of the capsule read by the code reader when the optically readable code does not correspond to the one of the last memorized optically readable codes.
