Method and system for filling thermally insulated containers with liquid carbon dioxide

A system for filling a compartment in an inner part of a container with an amount of liquid CO2, which is partially converted into an amount of solid CO2 upon injection of the liquid CO2 into the compartment, the system comprising:

• the container which is configured to contain one or more products and maintain the one or more products at a defined temperature, below a defined temperature, or within a defined temperature range, the defined temperature or the defined temperature range being below an environmental temperature, using the solid CO2;
• scale for subjecting the container to a weighing operation resulting in a weight of the container at least before and after the inner part of the container has been supplied with the amount of converted solid CO2;
• a barcode scanner, capable of scanning a barcode, provided with the container for generating barcode data;
• a calculator, capable of calculating a weight of the amount of converted solid CO2 to be supplied to the compartment in the inner part of the container, based on the barcode data;
• a filling gun, capable of filling the compartment in the inner part of the container with the amount of liquid CO2 which is at least partially converted into solid CO2 upon the injection of the liquid CO2 into the compartment, the weight of the container being monitored using the scale, until the weight of the container is equal to the weight of the container before the compartment in the inner part of the container has been supplied with the amount of converted solid CO2, increased by the weight of the amount of converted solid CO2;
• and
• a database, capable of storing the barcode data, and data on the weight of the amount of converted solid CO2, supplied to the compartment in the inner part of the container.
