摘要：
The present invention includes a gas flushing device that includes a piston portion having a hole to introduce the flushing gas. The present invention also includes a method for removing air from a container that stores food. The method includes providing the gas flushing device and aligning the device with the container. The method also includes moving the piston of the device into the container until the piston encounters a predetermined pressure. Next, the piston is retracted from the container while simultaneously releasing a flushing gas through the hole. Next, the piston is removed from the container and the container is sealed in an inert atmosphere.
