Where is the leak-proof device equipped on the plastic spherical cap usually designed?

Plastic spherical cup lid is equipped with leak-proof devices, which are usually designed inside the lid and include structures such as anti-overflow holes and anti-overflow grooves. Their function is to prevent the overflow of liquid by gravity when the cup is tilted or turned over, thus maintaining the stability of the liquid in the cup.

In daily life, we often use plastic cups to hold drinks or other liquids. However, when we tilt or turn the cup, the liquid is easily spilled, causing inconvenience and even pollution. To solve this problem, plastic spherical cup lids are equipped with leak-proof devices.

Leak-proof devices are usually achieved through the design of some special structures. For example, spill-proof holes can be placed inside the lid, located at the edge of the lid. When the cup is tilted or turned over, the liquid will flow into the spill-proof holes and enter the cup under the action of gravity, rather than spilling out.

The leak-proof device can also include overflow prevention slots. These slots are located on the top of the lid, and when the liquid overflows to a certain extent, they prevent the liquid from flowing back. In this way, the overflow prevention slots ensure that the liquid does not continuously flow out of the cup, thereby maintaining the stability of the liquid in the cup.

The design of these leak-proof devices is very useful. Whether in family life or in commercial settings, they provide convenience and hygiene. With these devices, users can use cups more freely without worrying about spilling liquids that can cause burns or stains.

The leak-proof device of the Plastic spherical cup lid also helps reduce waste. When liquid overflows, it can cause waste. By using the leak-proof device, we can ensure the stability of the liquid in the cup and reduce the waste of liquid.

The leak-proof device equipped on the Plastic spherical cup lid can prevent the spillage of liquid when the cup is tilted or turned over by designing structures such as anti-spill holes and anti-spill grooves, which can maintain the stability of the liquid in the cup. These devices not only facilitate user's use, but also help reduce the waste of liquid.
