摘要： The present invention relates to a multi-vacuum valve of a vacuum container. The present invention relates to a push button made from one selected from soft synthetic resin and soft silicone, comprising: a protruding annular rim protruding downward from the circumferential direction of the perimeter of a support part; a guide groove for the linear movement of a pressing part, which is recessed downward from a portion at which the outer circumferential end portion of the pressing part and the upper end of a height-varying part are in contact with each other; and a circular airtightness-maintaining rod for vertically moving downward by the pressing of the pressing part. The inflow/outflow of air, due to fine wear or damage caused by the cleaning of an airtight member, can be prevented and the inflow/outflow of air through a fine gap due to the distortion of the airtight member or gas pressure generated from food can be prevented, and thus a food storage period can be extended.

摘要： An airtight container has a lid which is easily opened by the principle of the lever thus preventing broth from splashing out when the lid is opened. The airtight container includes a container body having a latching bump and a bent flange, a rotating knob connected to the flange and having an opening-closing plate and a step portion, and a lid having a latching protrusion, a downwardly bent flange and a lid extension portion, wherein, when the rotating knob is just rotated upward in a state where the lid is coupled to the container body, the opening-closing plate lifts the lid extension portion by “the principle of the lever” while the step portion prevents the lid extension portion from spreading outwards, thereby allowing the latching protrusion to be released from the latching bump and the lid to be opened from the container body.
