Abstract: A vacuum container for preserving food is disclosed herein that includes a cover member for covering an upper part of a container member in which food is filled, a piston member equipped with the cover member and ascending and descending movable, and first and second valve members that alternately operate by a pumping operation using ascending and descending operation of the piston member to make a suction aperture and an exhaust aperture alternately open and close, thus discharging air from within the container member. Such operation allows the interior of the container member to become a vacuum state, thereby allowing food within the container member to be preserved for a longer time period, in a more sanitary manner, and a simple manufacture and a low manufacturing cost to provide users with convenience.

Abstract: The cooking pan in which one side of an outer circumferential face of a main body is combined with a handle through a bolt fastening has such a construction that a temperature display member is equipped with an upper face of a coupling end part combined with a guide protrusion of the main body, wherein the temperature display member is provided with a sense rod formed in one body from a lower portion of a display, the sense rod being closely inserted into a rod insertion hole of the coupling protrusion projected in one body from the main body, thereby displaying temperature transferred from the coupling protrusion so as to provide an easy cooking and the best taste of food and to prevent unnecessary consumption of fuel in cooking.
