Description

Sealing fresh-keeping cooker

The utility model relates to the Antistaling pot of store food.

One of food fresh keeping measure commonly used is to use refrigerator storage, but can't realize at areas without electricity.Someone utilizes pressure cooker also is a good method to food fresh keeping, but the safety valve of pressure cooker often causes pot outer air to the pot internal leakage, thereby fresh keeping time is shorter.

The purpose of this utility model is to provide a kind of sealing Antistaling pot, can make to be in complete sealing state in the pot.Prolong fresh keeping time.

The purpose of this utility model is to adopt following technical proposals to realize, the sealing Antistaling pot has a pot body, pot cover, deflating valve is housed on it, the uniform spinning groove more than three of pot cover periphery, spinning groove and horizontal plane have an inclination angle, and the lining lid is housed in the pot cover, its edge is equipped with O-ring seal, the cover cap that is threaded on the deflating valve is provided with rubber cushion in the cover cap, the bail of uniform and spinning groove equal number on the external wall of pot.Usage of the present utility model is to treat that fresh-keeping food puts into Antistaling pot, cover pot cover, bail snaps in the spinning groove, rotates pot cover, with pot cover and pot body good seal, with the Antistaling pot heat sterilization, the gas in the pot adds thermal expansion then, and a part of gas overflows from deflating valve, stop heating then and exist side by side soon that cover cap covers on deflating valve and firmly tightens sealing, along with temperature descends, be the negative pressure germ-free condition in the Antistaling pot, the food in it just can be fresh-keeping for a long time.

Compared with the prior art the utility model has sterilization thoroughly, and sealing is strong, the advantage of long fresh-keeping period.

The utility model is described in further detail below in conjunction with drawings and Examples
