A storage bin for a refrigerator appliance is provided. The storage bin defines a storage compartment for receiving food articles and may be removably received within a chilled chamber of the refrigerator appliance. The storage bin may further include a carrying handle, such that it is easily portable outside the refrigerator appliance. The storage bin may have cold pack material and/or insulating material in its walls such that the storage compartment remains cool for a period of time after the storage bin is removed from the refrigerator appliance. Due to the fact that the storage bin is chilled and easily portable, it is ideal for grocery shopping, for taking on a picnic, or for any other use involving travel with food items that must remain cool during transport.
