DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to a pot for heating and cooking food material, and more particularly to a pot having a lid for exhausting high pressure generated by heating, and automatically sealing the pot interior when heating ceases so as to maintain food material for long time without decomposition. The pot also has edge packing and an inverse flange on the lid to seal against outside air and preclude effluence of food material to the outside of the pot when boiled.
2. Prior Art
Generally, a pot is constructed simply by a vessel and a lid, and is used for cooking soup, stew etc. Rising interior pressure due to heating the pot is exhausted by an exhaust hole formed on the lid or a crack between the vessel and the lid so that an overflow of the food material can be prevented. However, since boiled soup can flow out through the crack, and the soup will push out the lid and overflow outside, this may cause problems such as contamination of the vessel contamination or extinguishing of the heating source. Further, the exhaust hole or the crack between the lid and the vessel promotes decomposition of the food within the pot.
DISCLOSURE OF THE INVENTION
Accordingly, the present invention is directed to a pot having an automatic sealing function that substantially obviates one or more of the problems due to limitations and disadvantages of the prior art.
An object of the present invention is to provide a pot having an automatic sealing function.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description as well as the appended drawings.
To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, a pot having the automatic sealing function is characterized in automatically exhausting high pressure generated in heating and simultaneously automatically sealing the pot interior when heating is stopped and the pot cools so that the food within can be kept for a long time without deposition, and minimizing an overflow of contents material in boiling the contents material.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
BRIEF DESCRIPTION OF THE DRAWINGS
