    Abstract: Apparatus and methods for removing excess fluid, and specifically gas, from a flexible container and sealing the container are provided. The apparatus comprises a device for receiving a flexible container including a product and having a first open end and a second sealed end located at an opposite end of the container from the first open end. The device includes an interior designed to receive at least a portion of the flexible container. The interior is defined, at least in part, by a compressible member that is so constructed and arranged so as to progressively squeeze excess gas located in the interior of the flexible container from the second sealed end out the first open end of the flexible container. The device also includes an integral sealing member that seals the first open end of the flexible container after the compressible member squeezes fluid from the interior of the flexible container.
