liquid nitrogen reason

The reason is the first couple liters of liquid nitrogen dispensed will immediately convert to a gas since the inner tank is hot. Since you are cooling the tank so fast, you will also get snowfrost in the neck and if you keep filling, the snowfrost will fall into the liquid nitrogen and stay.
