IDK what it's technically for but I know it helps keep the jug from busting when frozen.

I worked on a boat that would be at sea for 8-10 weeks at a time. we would freeze gallons of milk and this would pop out instead of cracking the container.

it's actually there to rip you off and not give you a full gallon. give it time and the bump will get bigger therefore even less milk

I always thought it's to let you know if the milk is spoiled. if bits popped out it's bad and fermenting
