MULTI-PUSH BUTTON FOR VACUUM FOOD STORAGE CONTAINER HAVING VACUUM VALVE
Abstract:
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.
