Today, let’s talk about the reasons why the water cup lid does not seal well. Of course, the sealing of the water cup is something that every water cup should achieve and do well. This is the most basic requirement. So why do the water cups purchased by some consumers become less sealing or even worse after being used for a period of time? Some cup lids are not sealed when they leave the factory. What is the reason for this?
The main reasons that usually cause the cup lid to seal poorly are:
1. The water-sealing design of the cup lid is unreasonable. This unreasonable design includes defects in engineering design, problems in the mold development process, and problems in the production process that are not up to standard.
2. The cup lid and cup body are deformed, causing the cup lid and cup body to not completely match.
3. The silicone ring that provides the sealing function is deformed or aged, which will cause the sealing silicone ring to fail to achieve the sealing effect.
4. The solution contained in the cup is corrosive. If the solution in the cup is highly corrosive, it will also cause the sealing of the cup lid to deteriorate.
5. The environment can also cause the cup lid to be poorly sealed, but this rarely happens, mainly because of the large air pressure difference between the inside and outside of the cup.
In addition to the above reasons, there are also some caused by material properties. Obvious changes in temperature induction of materials can also cause loose sealing. But no matter what the reason is for poor sealing, it can be solved through technology. The poor sealing performance of the water cup lid is as serious as the failure of the thermos cup to keep warm. Any water cup factory should fundamentally ensure the sealing performance of the water cup.
