Capsule for beverage preparation

A method for preparing a food or beverage from a container, the method comprising:

• (i) inserting the container in a food or beverage machine having a pressurized source of a mixing ingredient,
• (ii) establishing a fluid connection between the container and the pressurized source of the mixing ingredient,
• (iii) introducing the mixing ingredient within the container, and mixing the mixing ingredient with a precursor ingredient to create a food or beverage product, and
• (iv) delivering the food or beverage product to a consumer through a delivery wall of the container,
• wherein the connection between the container and the pressurized source of the mixing ingredient is performed by expanding outwardly an expandable connector of the container by mechanically connecting a catcher of the container to an expansion actuator of the food or beverage machine and then actuating the actuator to apply an outwardly directed thrust to the expandable connector such that a connection opening of the container is brought in a leaktight and fluid communication with a dispensing outlet of the pressurized source of the mixing ingredient.

A system for food or beverage preparation, the system comprising:

• a food or beverage preparation machine having at least one pressurized source of a mixing ingredient;
• and
• a container adapted for containing at least one precursor ingredient within at least one compartment, the container comprising an injection wall for coupling to the food or beverage preparation machine, a food or beverage product is prepared within the container by mixing the mixing ingredient with the at least one precursor ingredient, the container further comprising at least one food or beverage delivery wall, the injection wall comprises an outwardly expandable connector suitable for connecting the container to the at least one pressurized source of the mixing ingredient to establish a fluid communication between the container and the at least one pressurized source of the mixing ingredient, the outwardly expandable connector means comprising
• (i) a connection opening for conducting the mixing ingredient from the at least one pressurized source of the mixing ingredient towards an interior of the container when a fluid communication is established between the container and the at least one pressurized source of the mixing ingredient;
• (ii) an expandable wall portion of the container configured to be expanded outwardly with an increase of between 1% and 200% of an initial volume;
• and
• (iii) a catcher adjacent to the expendable wall portion, the catcher adapted for cooperating with an expansion actuator of the food or beverage preparation machine that applies an outwardly directed thrust to the outwardly expandable connector to expand the expandable wall portion.
