CAPSULE, BEVERAGE PRODUCTION MACHINE AND SYSTEM FOR THE PREPARATION OF A NUTRITIONAL PRODUCT

摘要

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.

主权项

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.
