Almighty group, what's the name of a teapot without a spout?

An ancient pot and an ancient pot is a new type of pottery pot invented by Mr. Deng Dingshou of Taiwan Province Province. Because of its originality in design, it was patented by the Bureau of Standards of Taiwan Province Province for fifteen years. In addition to the pot body, the traditional teapot in China consists of three parts: handle, lid and spout. However, the biggest disadvantage of traditional teapots is that the water flowing from the spout is not easy to master, and it is easy to overflow outside the cup when making tea. It also often causes the lid of the pot to fall off, causing damage, especially for small pots with exquisite craftsmanship. Once the lid is damaged, it will be a long-term regret. The ancient Yi pot invented by Deng Dingshou used the principles of airflow convection and siphon in physics to change the spout from the traditional sleeve on the side of the pot body to the center of the pot bottom. This cooperates with the small air hole designed on the lid of the pot to form a vertical line. In addition, an airtight seat is designed at the joint between the bottom of the pot body and the special pot seat, so that the pot body and the base are bonded to form an absolutely closed sealing state, so that when the pot is filled with water, tea leaves will not leak from the bottom of the pot (that is, the novel spout). When it is necessary to drink and pour the tea soup in the pot, just press the air hole on the pot cover with your index finger, lift the teapot, and open and close your fingers, so that the tea soup can be freely poured out (when pouring tea). This pot can not only effectively control the amount of tea soup, but also make the tea soup fall straight into the cup, so you don't have to worry about the tea splashing, and it won't cause the lid to fall off. In addition, because the pot body is highly sealed, the fragrance of tea leaves is maintained, and the brewed tea soup is more mellow than the traditional teapot.
