Description

Manual liquid outlet valve

technical field

The invention relates to other table utensils, in particular to an outlet valve used for liquid containers such as soy sauce, vinegar and edible oil.

Background technique

At present, most of the liquid containers such as soy sauce and edible oil in the domestic market are bottle-shaped containers, and the liquid outlets on the containers are bottle caps with simple structure. These bottle caps can only play a sealing role. It is necessary to unscrew the bottle cap. After use, in order to prevent the solution from accidentally touching the bottle body and causing the solution to spill, the bottle cap needs to be tightened again, which is extremely inconvenient for repeated use; moreover, the liquid outlet of this bottle body is generally larger , the amount of liquid that flows out cannot be well controlled when a small amount of use is required. There are also some soy sauce, edible oil and other containers with pouring spouts on the market. Although it is not necessary to unscrew the bottle caps every time they are used, such containers are easy to spill after being knocked over, which is unhygienic and easy to cause waste. .
