A squeezer and fluid discharge system and method are disclosed. The fluid discharge system includes a container, a liner bag, a squeezing device and a driving device, the liner bag is installed in the container, and the driving device is connected to the squeezing device and used to drive the squeezing device. The squeezing device comprises at least two rollers, and the liner bag is formed by welding a front panel and a rear panel and is provided with a discharge port which is arranged adjacent to the weld line at the bottom of the liner bag.

The invention relates to a valve bag, in particular a cross-bottom valve bag, comprising a first wall and a second wall, which are joined to each other by means of side edges or side folds and by means of bottoms and which delimit a bag interior, comprising a valve, which is arranged in one of the bottoms and via which the bag interior can be filled with a filling material, and comprising venting openings in the first and/or in the second wall for venting the bag interior. At least one channel is provided on the outside of at least one wall, which channel covers the venting openings and is formed at least by two parallel fastening strips and by a cover strip, the cover strip likewise comprising venting openings, and wherein the shortest path between the parallel fastening strips along the cover strip is longer than the shortest path along the at least one wall or the cover strip, and/or the parallel fastening strips consist of stretchable material.

A bag includes: a bag body at least having a first surface and a second surface facing each other with a storing space formed between the first surface and the second surface; and a tape member provided between the first surface and the second surface and defining one side of the storing space. The tape member includes, in a cross section, a first portion formed of a first resin composition and a second portion formed of a second resin composition different from the first resin composition. The first portion is bonded to both the first surface and the second surface at a first section of a longitudinal direction of the tape member while bonded to only the second surface at a second section of the longitudinal direction, and the second portion is bonded to the first surface at the second section.

A tissue graft container is provided having an interior space and including a vent which allows fluid (liquid and vapor) to escape from the container during drying of the tissue graft. The vent may be one or more apertures, one or more elongated openings, or a combination thereof, through one or more components of the container. A tissue graft packaging system having a retainer including first and second members with respective first and second pluralities of channels, and configured to removeably interconnect the first and second members in a closed configuration. The first and second pluralities of channels create a continuous interior space. The retainer further includes a vent, such as apertures, slits, etc., through one or both of the first and second retainers, for allowing moisture to escape from the retainer during the drying of a tissue graft contained within the continuous interior space of the retainer.
