anti-scald straw / straw

anti-scald straw

We often use a straw to drink, but when it comes to hot drink, straws turn into hidden troubles. It’s generally hard to tell if the beverage is fit to drink only when we took a sip, which makes it easy to get scalded.Anti-scald Straw has a heat-sensitive paint ring inside it near the end, which is made of heat-sensitive material that can expand quickly to block the straw when the drink is too hot, directly prevent from sucking in superheated drink. When the temperature falls to a suitable degree, the ring shrinks to let the drink pass through. It presents an apparent signal to let users know whether it is suitable to drink.
