How to treat the tightness of the lid of the water cup?
As an old factory producing drinking glasses for nearly 20 years, as a worker in the drinking glass industry for many years. Over the years, our company has developed as many as hundreds of water cups with different functions. No matter how individual the design of the water cup is or how trendy the function development is, the tightness of the lid of the water cup is the most important for us, also is the most basic.
To make an analogy, is the lid of the water glass well sealed? Will it leak? These problems should not be a problem for water cup manufacturers. The water cup production factory should 100% guarantee that the lid of any water cup that leaves the factory is well sealed and 100% will not leak. The most important thing is that if a water cup is in use and the lid does not have a sealing effect, then this water cup has no reason to be produced, and even if the airtightness cannot be achieved, it is not a qualified water cup. (Except for specific design styles)
It's like buying a car, but without a steering wheel. Basically speaking, without considering the use of other functions, the water cup should at least be sealed and not leaking, otherwise it will lose the meaning of the water cup as a water carrying tool. It's like buying a car without wheels.
Whether it is in life or in business contacts or exhibition activities, we meet friends who ask such questions, we respect and understand each other from the heart, indicating that these friends may have experienced the leakage of buying water glasses. Therefore, we will patiently tell our friends how we do not leak water, and how to identify the possibility of water leakage through simple methods when buying water cups.
