Description

Container cover and container

Technical Field

The application relates to the technical field of kitchen utensils, especially relates to a container lid and container.

Background

The micro-pressure cooker is a cooking pot which is popular in recent years, when the micro-pressure cooker works, a certain pressure can be kept in the cooker, cooked food is more delicious than common pots, and because the internal pressure of the micro-pressure cooker is far lower than that of a high-pressure cooker, the strength and the structural requirements are lower than those of the high-pressure cooker. The structure of the prior micro-pressure cooker comprises a cooker body with a handle and a sealing cooker cover which can be covered on the cooker body, the cooker body and the cooker cover realize sealing butt joint through a sealing ring which is arranged around the periphery of the cooker cover, and an exhaust valve for pressure relief is arranged on an opening on the cooker cover. After the micro-pressure cooker is cooked, the air pressure is discharged along with the exhaust valve, so that the air pressure of the cooker body is reduced, and the negative pressure phenomenon occurs in the micro-pressure cooker; or when the pot cover is covered on the pot body, the pressure in the pot body is reduced due to the weight of the pot cover and the compression of the sealing ring, so that the negative pressure phenomenon occurs in the micro-pressure pot. When negative pressure phenomenon appears in the micro-pressure cooker, under the effect of internal and external pressure difference, the cooker cover cannot be directly opened, but an exhaust valve needs to be pushed first, so that the inside of the micro-pressure cooker is communicated with the external environment, the negative pressure phenomenon in the micro-pressure cooker is eliminated, the cooker cover is opened by lifting the handle, and the process of opening the cooker cover needs two operations: the operation of opening the pot cover is complicated due to the pushing of the exhaust valve and the lifting of the handle.
