Spill-proof pot cover

Abstract

The invention discloses a spill-proof pot cover, which comprises a cover body, a cover rim and a handle, wherein the handle is located on the cover body; the cover rim is located at the edge of the cover body; a downward step is disposed between the cover body and the cover rim; the cover rim comprises a cover rim plate, expansion bars, a connection nail, a step and a lateral clamping bar; the swelling bars and the lateral clamping bar are made of upper and lower layers of materials; the thermal expansion coefficient of the upper layer of material is greater than that of the lower layer of material; the expansion bars are disposed below the cover rim plate and are fixed on the cover rim plate or the cover body through the connection nail; and one side of the pot cover is provided with theexpansion bars, and the other side of the pot cover is provided with the clamping bar. The spill-proof pot cover is used like a common pot cover; the spill-proof pot cover covers a pot till the coverrim is fitted to a pot rim; and when a temperature in the pot rises up gradually, the expansion bars downwards upwarp to reserve a gap between the cover rim and the pot rim, so that water vapor can spill from the gap to reduce the phenomenon of spilling of soup.

Description

technical field [0001] The invention belongs to the field of kitchen utensils, and relates to a pot cover capable of preventing soup from overflowing the pot. Background technique [0002] The soup pot should be covered with a lid, but when cooking noodles and rice porridge, the water in the pot will gradually rise after the soup boils, and finally overflow the pot when the lid is opened. The higher the starch content of the soup, the higher the viscosity of the soup. , The higher the consistency of the soup, the more likely it is to overflow the pot, so the lid of the pot should be opened in time after the water in the pot is boiled, otherwise it is inevitable that the soup will overflow. Seriously, put out the furnace fire to cause the gas to leak and there is a danger of a gas explosion, so how to prevent the soup from overflowing when cooking soup is a problem that has always existed in the kitchen. Contents of the invention [0003] The purpose of the invention is to...
