Structural front and rear frames, and a rear bulkhead mounted on the rear frame, mount and securely retain a flexible bag as a liner within a freight container, truck trailer or the like, to adapt the container for bulk cargo transport. The front frame retains the front end of the liner bag in generally rectangular configuration and transmits stresses on the bag to structural members of the container, thus supporting the front end of the bag against displacement and possible damage or rupture. The rear frame and a curved bulkhead mounted thereon support the rear end of the bag and similarly prevent its rupture or collapse during loading and tilt-unloading. The laterally curved rear bulkhead also acts as a funnel to completely evacuate the bag contents during tilt-unloading through an opening therethrough. The arrangement is inexpensive and easy to install and, although all of its components may be disposed of after a single use, at least the frame components can be reused.
In a cargo container of the type having a floor, side walls, a roof, and a front wall, and wherein the roof structure includes downwardly projecting structural members, a liner bag adapting the container for receiving bulk cargo, and means for supporting said liner bag within the container comprising front frame means including a bottom cross member substantially on and extending transversely across the container floor, a pair of substantially parallel side members extending upwardly and rearwardly from the respective ends of said bottom cross member, said side members having upper end portions engaging forwardly facing surface portions of one of said downwardly projecting structural members, and means bracing said side members apart adjacent to their said upper end portions and including a top cross member extending between said side members and generally parallel to said bottom cross member, said liner bag having a transversely extending bottom front end area connected substantially to said front frame bottom cross member and a transversely extending upper front end area connected to said front frame top cross member.
In a cargo container of the type having a floor, side wall, a roof, a front wall, and a rear door frame, a liner bag adapting the container for receiving bulk cargo and having respective transversely extending upper and lower front end attachment areas, and means for supporting said liner bag within the container comprising front support means including a bottom cross member extending transversely substantially across said front wall of the container adjacent to its said floor means retaining said bottom cross member in its said position, said liner lower front end attachment area being connected substantially to and extending along said bottom cross member, and means retaining said liner upper front end attachment area substantially adjacent to and extending transversely substantially across said front wall of the container at a height location above said bottom cross member whereby, when said container is tilted to unload said bulk cargo via its said rear door frame, said front end bottom cross member retains said liner lower front end attachment area in position substantially adjacent to the juncture between said front wall and said floor.
In a cargo container of the type having a floor, side walls, a roof, a front wall, and a rear door frame, a liner bag adapting the container for receiving bulk cargo and having respectively transversely extending upper and lower front end attachment area, and means for supporting said liner bag within the container comprising front support means including a top cross member extending transversely substantially across said front wall of the container at a height location above said container floor and means retaining said top cross member in its said position, means connecting said liner upper front end attachment area substantailly to and extending along said top cross member, and means retaining said liner lower front end attachment area substantially adjacent to and extending substantially along the line of juncture between said front wall and said floor whereby, when said container is tilted to unload said bulk cargo via its said rear door frame, said front support means retains said liner upper front end attachment area in substantially said position adjacent to said front wall of the container.
In a cargo container of the type having a floor, side walls, a roof, a front wall, and a rear door frame, a liner bag adapting the container for receiving bulk cargo, said liner having a front end and a transversely extending upper rear end attachment area, and means for supporting said liner bag within the container comprising front support means retaining said liner front end substantially adjacent to said container front wall, and rear support means comprising substantially vertical bulkhead means extending across said container adjacent to, but spaced forwardly away from said rear door frame and bulkhead support means retaining said bulkhead means in its said position, the rearward end of said liner bag being against and supported by said vertical bulkhead means when said liner bag contains said bulk cargo, and means retaining said liner upper rear end attachment area substantially adjacent to and extending transversely across said roof of the container comprising a rear end upper cross member extending transversely substantially across said container adjacent to its said roof and means retaining said upper cross member in its said position, said liner upper rear end attachment area being connected substantially to and along said rear end upper cross member.
In a van-type cargo container having a floor, sidewalls, a roof, a front wall, and a rear doorway, a liner bag adapting the container for receiving bulk cargo, said liner bag having respective front end and rear end portions, and means for supporting said liner bag within the container comprsing front support means including front cross member extending substantially across and adjacent to said front wall of the container, said front support means supporting said liner bag front end portion substantially against said container front wall in a generally rectangular configuration which extends across said container front wall substantially adjacent to said floor and upwardly from the latter substantially adjacent to the respective of said sidewalls, and means securing said front support means in such position, said liner bag having front end attachment areas connected substantially to said front support means whereby, when said container is tilted to unload said bulk cargo from said liner bag via said rear doorway of the container, said front support means retains said liner front end attachment area substantially adjacent to said front wall of the container.
