AI Technical Summary

Problems solved by technology

[0004] The disadvantages of this kind of pot or bottle cap are: 1. The cap plug and the pot body are threaded. When pouring water, it is necessary to unscrew the cap plug first, which is laborious and not convenient to use.

2. Since the outlet of the lid plug can be opened by pressing the button, and it cannot be closed automatically, the lid plug is often opened by mistake or forgotten to close the lid plug due to the button being touched during use, causing the temperature of the soup in the pot to drop rapidly or the consequences of unsafe use of poured soup

3. The difference between the button-type open / closed states on the cover plug is not obvious. Users must check carefully to distinguish the two states when using it. It is easy to happen that the cover plug is not closed, resulting in unsafe use consequences.
