Abstract: This device has three main components: a storage container, an air-tight lid and a pump for extracting air. The storage container is distinguished by a ring-shaped protrusion in the concave bottom of the container. This protruding ring is designed to fit tightly into a concave ring on the lid of another container of the same design. This feature enables the containers to be stacked conveniently on top of one another. The storage container is further distinguished by an elevated lip on the upper rim of the container, which forms an air-tight seal with the lid. The lid is distinguished by a vacuum valve containing two layers with several holes in each layer. The vacuum valve contains an umbrella-shaped silicon piece, which can bend upwards to allow air to be drawn out by the pump, but is restricted from bending downwards (which would allow air to enter the container).
