    Abstract: A structure of vacuum sealing container for food and other objects that can prevent reverse flow of air while preventing content and water inside the vacuum sealing container. The vacuum sealing container is able to create a vacuum condition so that a content such as food or medicine can be stored inside the vacuum sealing container for a long period of time. The vacuum sealing container has a check valve that allows to expel air inside the vacuum sealing container to the outside to create a substantially vacuum condition, a re-sealable zipper that can air-tightly close the vacuum sealing container. The check valve is made of films that prevents reverse flow of air, part of which includes moisture permeation waterproof material to prevent flow of liquid inside the vacuum sealing container to the outside.
