Abstract:
A portable reservoir frame has a plurality of panels that form an enclosure when adjacent panels are connected. Each panel has a plurality apertures spaced at intervals along a first side edge and that extend through each panel between the exterior face and the interior face, and a plurality of male members spaced at intervals along a second side edge and protruding from the exterior face of the panel. Each male member is sized to extend through a corresponding aperture in the adjacent panel with the remote end protruding. There is one or more locking bar that has a plurality of receivers that, when installed, extends along the second side edge of the panel and simultaneously engages a plurality of male members. The receivers engage the peripheral engagement on the body of the male member and prevent the male member from being withdrawn from the aperture.
Abstract:
A cylindrical upstanding water tank is formed from a plurality of rows of corrugated curved panels bolted edge to edge with a liner extending over the cylindrical wall and support surface to contain the water within the tank. An access opening is formed in one panel of the cylindrical wall and includes a frame with a rectangular planar front flange and a rearwardly extending flange welded into the hole. Liner retention straps surround the hole to fasten an edge of the liner around the hole. An access cover plate is bolted to the front flange of the frame and carries a hoop strength plate which fastens to studs at the rear of the plane so that the plates are removable to allow service access to the interior of the tank.
Abstract:
A collapsible portable tank for storing liquids has a liquid impervious liner. The side walls of the liner are supported by a collapsible frame. A plurality of hand grips in a zigzag pattern on the floor panel of the liner facilitates manipulation of the liner to collapse the liner with the frame. The liner floor panel is of heavier material than the side walls and is heat sealed along its entire perimeter to the liner side walls, affording a more durable floor while eliminating clumsy excess liner material at the corners of the tank. Another hand grip on the floor panel opposite a drain in the liner side walls facilitates evacuation of stored liquid from the tank prior to collapsing the tank.
Abstract:
Layers of material are bonded together to include portions that yield an integral filling conduit or snout in a completed single or multiple-ply bag particularly useful in bag-in-box shipping containers. The layers are bonded to form the preferred shape of a trapezoid whose long base is parallel to and runs into the top of a rectangle, the bonds forming seams on the sides of the trapezoid and the sides and base of the rectangle. Alternatively, half the number of layers can be folded and bonded to yield the trapezoid/rectangle shape, in which case no base seal is required. The trapezoid's short base is the snout opening and, where necessary, interply bonds are formed around the opening circumference. The invention can also be formed with an evacuation enhancement system that uses an inflatable air chamber in an interply region to cause more of the bag contents to be discharged than would otherwise occur. Interply bonds in two key locations form the air chamber, and an air input conduit included between the plies allows access to the interply region. In use, the filled bag's edge seals preferably lie in the corners of a rigid container with the air input conduit, when present, against a side of the container opposite the bag's drain port and connected to a source of pressurized air. As the enhanced evacuation system bag contents level drops, the air chamber inflates and urges the contents toward the drain port.
Abstract:
A collapsible container system for flowable materials includes a collapsible bag for holding the materials and a collapsible frame for supporting and retaining the bag. The collapsible frame includes top and bottom portions and a plurality of spaced apart upright members extending therebetween. The upright members each include a removable support portion that normally extends in a generally vertical direction and in supporting relation between the top and bottom portions. When all of the support portions are removed from supporting relation between the top and bottom portions the frame is collapsible and its height is reduced.
Abstract:
Container apparatus (2) for transporting and storing fluid material, comprising a flexible bag (8), a rigid frame member (10) which is attached to an upper portion of the flexible bag (8), a rigid base (12), and elongate support members (16) which are positioned outside the flexible bag (8) and which are movable from a first position in which they extend between the rigid frame member (10) and the rigid base (12), to a second position in which they allow the sides of the flexible bag (8) to collapse, and the container apparatus being characterized in that the rigid frame member (10) is provided with inboard portions (13) which are attached to the sides (9) of the flexible bag (8) thereby to draw the sides of the flexible bag substantially inboard of the rigid base and force the fluid material towards corners of the flexible bag which are formed by points of attachment of the flexible bag to corners of the rigid frame member and to create an upper portion to the flexible bag which has opposing sides which are inclined toward each other in order progressively to reduce the volume for a liner bag (6) to occupy as it is filled, and characterized in that the container apparatus is free of constraint members which extend parallel to the rigid base to constrain the sides of the flexible bag.
Abstract:
A tank (2) specially suited for transporting slurries, such as wine grapes (60), while reducing the tendency of the slurry to surge during transport. The tank includes an outer frame (6) and an inner container (4). The frame, typically made of steel, defines a central open region (5) within which the container is supported. The container is preferably plastic, or other thermal insulating material, to reduce heat transfer through the walls of the containers to the slurry. The circumferential sidewall (8) of the container has vertical corrugations (52) sized and spaced to inhibit surging of the slurry material within the tank during transport on a truck (47).
Abstract:
There is disclosed a rigging frame (10) having legs (15) whose lengths are adjustable to suit the frame for different sizes of "big bag" to avoid need for adjustment of the support means of a discharging machine.
Abstract:
This invention relates to equipment assisting the discharge of particulate materials from intermediate bulk containers of the kind comprising an outer bag having an inner lining comprising frame members to which the upper end of the outer bag of an intermediate bulk container can be anchored, cord devices extendable against the action of resilient devices and adapted to be connected with the upper end of an inner liner to the outer bag, pulley devices for guiding the cord devices to the position of connection with the liner, a pivoted arm and devices for attaching the free end of the cord devices to the arm at a position spaced from its pivot, the arrangement being such that the arm can be swung to carry the free end of the cord means to a position for connection with the liner.
Abstract:
There is disclosed apparatus for facilitating discharge of material from a bag having an inner liner. A cord is provided which can be extended from resilient return reel for connection with the top of the liner so that the liner is pulled as the bag empties.
