A container system includes a one-piece, one-way valve. The container system can be evacuated by pressing the lid, thereby forcing air out of the one-way valve. The one-way valve does not allow air to enter the container system. The one-way valve includes an interface or release which allows air to enter the container system when the interface is pressed. The one-way valve is preferably an umbrella-shaped valve made of a silicone or plastic.

[ What is claimed is:] [1.] A container system, comprising:a container base having an opening:a lid configured to sealably engage the opening and to cover the container base, the lid providing a substantially air-tight interface between the lid and the container base when the lid slidably engages the opening, the lid having a vent aperture;a valve disposed in the vent aperture the valve allowing gas to escape the container system when the lid is deformed and allowing gas to enter the container system when the valve is moved; andwherein the valve is an umbrella-shaped plug, the plug includes a plurality of rounded members in contact with a top surface of the lid, the plug has a feathered periphery for contacting the top surface of the lid and preventing gas from entering the container system through the vent aperture, and the rounded members act as a fulcrum for lifting the feathered periphery from the top surface to allow the gas to enter the container system through the vent aperture when the valve is pressed.
