Just Burp It
The STOP IT™ is the ultimate sealing system for your tumbler. The air-tight seal makes it perfect for intermittent extreme spill protection. The STOP IT™ can withstand pressure levels higher than that of your tumbler lid so some care needs to be taken for your safety. If leaving the STOP IT™ closed for an extended period of time, keep it upright; then check the lid and vent the pressure when using again.
WARNING:
When using the STOP IT™ for hot beverages it is important to fully purge all cool air in your tumbler before closing the STOP IT™. Otherwise, the hot beverage may heat the air inside the tumbler which creates pressure that can cause the tumbler lid to lift. This could allow the hot beverage to spill which may result in injury or property damage.
NOTICE:
As cold beverages heat up to room temperature the pressure will also increase slowly which may cause the lid to also slowly lift. This is generally prevented by normal use, but when closed for an extended period of time do not leave on its side in order to prevent property damage.
