Methods for pre-charging carbon dioxide snow

A method of supplying a perishable item to a location, comprising the steps, of:

• receiving a pre-charged container at least partially filled with CO2 snow inside the pre-charged container;
• opening the pre-charged container at least partially filled with the CO2 snow;
• accessing an interior region of the pre-charged container at least partially filled with the CO2 snow;
• loading the perishable item into the pre-charged container at least partially filled with the CO2 snow, wherein the perishable item is in sufficient proximity to the CO2 snow to maintain a temperature of the perishable item below an upper limit;
• re-sealing the pre-charged container at least partially filled with the CO2 snow;
• preparing the pre-charged container at least partially filled with the CO2 snow with the perishable item therein for delivery to the location.

A method of delivering at least partially depleted CO2 snow pre-charged container, comprising:

• receiving the at least partially depleted CO2 snow pre-charged container, said at least partially depleted CO2 snow pre-charged container further comprising one or more perishable items in sufficient proximity to the CO2 snow to maintain the temperature of the perishable item below an upper limit;
• opening the at least partially depleted CO2 snow pre-charged container to access the interior of the pre-charged container;
• removing the one or more perishable items from the at least partially depleted CO2 snow pre-charged container;
• and
• delivering the at least partially depleted CO2 snow precharged container to a location for charging, loading additional perishable items or using at least a portion of the one or more perishable items remaining in the at least partially depleted container CO2 snow pre-charged container.

A method of creating a pre-charged insulated container with CO2 snow at a first location for transport to a second location, comprising the steps of:

• providing a source of CO2 snow at a first location;
• introducing the CO2 snow into an empty or partially empty container at the first location;
• creating the pre-charged insulated container;
• and
• preparing the pre-charged container for delivery to the second location.
