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.
