What is this 'three-legged tripod' in every pizza box used for?

Despite being a fan of pizza, do you know the true use of this 3-legged plastic base?

Would you like to eat pizza and you will always take advantage of the opportunity to buy 1 get 1 on the promotion day to order some home items to meet with friends?

But have you ever wondered if every time you order a pizza home, your cake is always accompanied by a 3-foot plastic base placed in the middle of the cake? What do they exist to do? Here answer!

Anyone who eats pizza knows this 3-legged base, but not everyone knows what its use is.

The white plastic 3-foot base is actually called "pizza saver" - it works to prevent the bottom pizza from sticking to the lid of the cake box.

It is known that this plastic 3-foot sole was invented on February 10, 1983 by Carmela Vitale from New York and was awarded a patent in 1985.

In its patent, "pizza saver" is said to be a "divine" invention that helps maintain the structural integrity of pizza.

Original design of "pizza saver".

We know that pizza boxes are made from cardboard boxes. When the hot pizza is placed in the box, the area in the middle of the lid is easily sagged under the action of steam.

The longer the pizza in the box, the more concentrated the steam inside the box and makes the lid "soft" , easily collapsed. If there is no "anti" object, the pizza lid will stick to the cheese part, the types of pizza until the box opens.

If there is no "anti" object, the pizza lid will stick to the cheese part, the types of pizza until the box opens.

And the other "3-legged tripod" can solve it all. With plastic material and leaving no imprint on the cake (only 3 small dots), the pizza saver will resist the central part of the lid, not letting them "collapse" to ruin the cake during storage. And shipping.
