A hermetic food container consisting of a rotary knob, a top cover, a container body, a guide seat and a gasket ring is disclosed. The rotary knob is moved upwards or downwards relative to the top cover to achieve a sealing effect or to create a gap for enabling air to pass therethrough into the container body when the rotary knob is rotated in one of two reversed directions. The use of the gasket ring can effectively reduce wear, enhance durability and prolong the lifespan of the hermetic food container. Further, an anti-slip cushion is provided at the bottom side of the container body, allowing multiple hermetic food containers to be arranged in a stack convenient for storage, package and delivery.

1. A hermetic food container, comprising a rotary knob, a top cover, a container body, an ornamental cover, a guide seat and a gasket ring, wherein: said rotary knob is rotatably connected to a top side of said top cover, comprising a bottom stem downwardly inserted through said top cover and fastened to said guide seat with a fastener, a position-limiting groove extended around the periphery of said bottom stem, an annular peripheral wall spaced around said bottom stem, and an anti-slip cushion mounted around said annular peripheral wall;said top cover is capped on said container body, comprising a face panel, a rim extended around the border of said face panel, a packing rubber fastened to said rim, a coupling hole cut through opposing top and bottom walls of said face panel at the center and rotatably coupled with said bottom stem of said rotary knob, and at least one lift guiding block located on the top wall of said face panel, each said lift guiding block comprising a guiding surface sloping downwardly from one end thereof to an opposite end thereof for guiding said rotary knob to move upward relative to said top cover when said rotary knob is rotated in a first direction;said container body defines therein an open-top storage chamber;said ornamental cover is fastened to a bottom side of said top cover;said guide seat is fixedly fastened to said rotary knob for synchronous rotation, comprising at least one guide block, each said guide block defines a guiding surface sloping downwardly from one end thereof to an opposite end thereof for guiding said rotary knob to move downward relative to said top cover when said rotary knob is rotated in a second direction reversed to said first direction;said gasket ring is fastened to said position-limiting groove of said bottom stem of the rotary knob so that when said rotary knob is lifted relative to said top cover, said gasket ring is forced into abutment against an inner peripheral wall of said coupling hole of said top cover to achieve a sealing effect; when said rotary knob is lowered relative to said top cover, a gap is created between said gasket ring and said inner peripheral wall of said coupling hole of said top cover. 2. The hermetic food container as claimed in claim 1, wherein said container body further comprises a bottom rim downwardly extended from the border of a bottom side thereof and defining therein an accommodation space, and an anti-slip cushion fastened to said bottom rim; said face panel of said top cover provides a recessed configuration in a top side thereof fitting the configuration of said anti-slip cushion.
