Abstract
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.
