  • the bulk bag 10 is provided with a plurality of vertically extending pockets 26. Each of the pockets 26 receives a support member 30 therein.
  • the support members 30 may be either solid or tubular, for example, the support members 30 may comprise PVC pipe which is readily available and inexpensive.
  • the support member 30 function to retain the side walls 12 of the bulk bag 10 in an upright, open configuration.
  • bulk bags are often square or rectangular in cross sectional configuration, thereby defining four corners. In such instances it is convenient to attach the pockets 26 at the corners of the bulk bag, however, attaching the pockets at the corners is not required in the practice of the invention. Rather, the pockets 26 may be attached at any,convenient location.
  • Bulk bags having a single tubular side wall are also widely used.
  • the pockets 26 may be attached to the side wall thereof at any convenient location around the periphery of the bulk bag.
  • the number of pockets used in conjunction with a particular tubular bulk bag depends upon the requirements of particular applications of the invention, it being understood that larger diameter tubular bulk bags will typically require a larger number of pockets 26.
  • FIGs 2 through 5 illustrate various techniques for constructing the pockets 26 .
  • the fabric of the side walls may extend to form a loop which is then closed by sewing as indicated by the sew line 32.
  • the sew line 32 may be used to close the seam.
  • FIGs 4 and 5 illustrate embodiments of wherein the pocket 26 is constructed independently of the fabric of the side walls of the bulk bag.
  • the side walls 12 are joined at one of the corners of the bulk bag by a seam 40.
  • a pocket 26 comprises panels 42 and 44.
  • the sew line 32 performs the triple function of closing the seam 40, joining the panels 42 and 44 along adjacent edges thereof, and securing the pocket 26 to the bulk bag.
  • the seam 36 joins the panels 32 along the opposite edges thereof thereby completing the construction of the pocket 26.
  • Figure 5 illustrates a similar construction wherein the pocket 26 is formed from a single panel 46.
  • the sew line 32 performs the triple function of closing the seam 40, joining the adjacent edges of the panel 46 to complete the construction of the pocket 26, and securing the pocket 26 to the bulk bag.
  • Bulk bags incorporating the present invention may be formed using U panel, tubular, or four panel construction.
  • the corner pockets are dimensional to receive rods or tubes having diameters between about 1 ⁇ 2" and about 2".
  • the pockets may be formed as part of the side panels of the bag, or attached to the side seams.
  • the pockets are made of bulk bag fabric, narrow fabric webbing, or in lieu of pockets straps are used in multiple locations in the side seams.
  • Various lift loop styles may be used including standard four corner vertical loops, spread straps, over-the-corner straps, basket straps and sleeves.
  • the bulk bag may also have tabs, straps, or loops attached to various points at the bottom of the bags to be used to secure the bottom of the bag to the tip over discharge equipment.
  • each pocket may have a closure device or the pocket can be left open.
  • the bulk bag 50 comprises four side walls 52 and a bottom wall 54 ( Figs. 7 and 9 ).
  • the side walls 52 and the bottom wall 54 define a rectangular enclosure.
  • the side walls 52 intersect at corners which define vertically disposed pockets 56 located outside of the rectangular enclosure.
  • a reinforcing band 58 is provided along the tops of the side walls 52, and is secured by seams 59.
  • the bottoms of the side walls 52 are joined to the bottom wall 54 by seams 61.
  • the bulk bag 50 is constructed from four corner panels 62, 64, 66, and 68. As is best shown in Figure 8 , the opposite vertically extending edges of each of the corner panels are folded over and adhesively secured at to provide reinforced edges 70. Referring again to Figure 6 , the reinforced edges of the corner panels are joined by side seams 72 to define the bulk bag 50.
  • the bulk bag 50 is provided with lift loops 74 which are secured to the fabric of the corner panels by sewing along seams 75. As is shown in Figure 11 , the lift loops 74 are secured to their respective corner panels by the side seam 72 and by the seams 59 which secure the reinforcing band 58.
  • the lift loops 74 are secured to the side walls 52 by seams 75. In this manner the lift loop 74 is secured in an upright configuration to facilitate manipulation of the bulk bag 50 by forklift trucks and similar apparatus.
  • Securing loops 76 are provided at the bottom of each corner of the bulk bag 50.
  • the securing loops 76 are secured to the bulk bag 50 during construction thereof function to secure the bulk bag 50 to a conventional tip over apparatus (not shown) to facilitate discharge of the contents of the bulk bag 50.
  • the pockets 56 are constructed from the fabric of the corner panels comprising the bulk bag 50 and a seam 77 in a manner similar to that shown in Figure 2 and described hereinabove in conjunction therewith.
  • Each corner pocket 56 is located outside of the rectangular enclosure defined by the side walls 52 and receives a structural member 78 which preferably comprises a length of PVC pipe.
  • the function of the structural member 78 is to maintain the bulk bag 50 in an upright and open configuration to facilitate filling thereof.
  • each pocket 56 is provided with a sewn-in-place shield 80 which prevents contamination of the interior of the pocket 56 during filling of the bulk bag 50.
  • the lower end of each pocket 56 is provided with a releasable closure 82 which secures the structural members 78 within the pocket 56 during filling, transport, and discharge of the bulk bag 50, while facilitating removal of the structural members 78 after the bulk bag 50 has been emptied.
  • the releasable closures 82 preferably comprise tie down straps, however, other releasable closure configurations will readily suggest themselves to those skilled in the art.
  • the bulk bag 50 further includes a liner 84.
  • the main portion of the liner 84 extends across the bottom wall 54 of the bulk bag 50 and then upwardly along the side walls 52 thereof. At the upper ends of the side walls 52 the liner 84 is folded inwardly and then extended downwardly to define a skirt 86.
  • An important feature of the bulk bag 50 comprises the fact that the liner 84 is secured to the upper ends of the side walls 52 by tabs 88.
  • each tab 88 comprises a layer of plastic tape 90 of the type comprising longitudinally extending lengths of reinforcing fibers.
  • Each tab 88 includes a sectional of woven polypropylene fabric 92 at the upper end thereof which is secured to the tape 90 by a suitable adhesive and which is sewn into the reinforcing band 58.
  • the liner 84 and the skirt 86 thereof are secured to the tab 88 by means of a suitable adhesive.
  • the tab 88 may be provided with an additional length of woven polypropylene fabric 94 which further secures the tab 88 against tearing.
  • the reinforced edges 70 of the corner panels 62, 64, 66, and 68 comprise doubled-over edge portions of the fabric comprising the corner panels which are secured in place by adhesive layers 96.
  • the upper portions of the reinforced edges 70 are doubled over and are secured in place by the seams 59 which also function to secure the reinforcing band 58 in place.
  • the seams 59 also secure the tabs 88 to the side walls 52 of the bulk bag.
  • the lift loops are secured to the reenforced edges of the corner panels 62, 64, 66, and 68 by the seams 75.
  • the bulk bag 50 is typically filled with a quantity of meat products MP.
  • the securing loops 76 are utilized to secure the bulk bag 50 to a conventional tip over apparatus (not shown) of the type utilized in conjunction with prior art meat product transporting devices. After the securing loops 76 are secured to the tip over apparatus, the tip over apparatus is utilized to invert the bulk bag 50 so that the meat product MP can be discharged therefrom.
  • FIG 13 illustrates an early step in the discharge of the meat product MP from the bulk bag 50.
  • the bulk bag 50 is shown partially inverted with the meat product MP beginning to pour outwardly from the liner 84 of the bulk bag 50. Because of the sticky nature of the meat product MP, discharge thereof tends to pull the liner 84 out of the bulk bag 50. However, outward movement of the liner 84 relative to the bulk bag 50 is restrained by the tabs 88 which secure the liner 84 to the upper end of the bulk bag 50.
  • Figure 14 shows the bulk bag 50 completely inverted with the restraining loops 76 still securing the bulk bag 50 to the tip over apparatus.
  • the liner 84 is pulled outwardly from the interior of the bulk bag and is turned inside out.
  • Figure 15 illustrates the bulk bag 50 with the discharge of the meat product MP therefrom substantially complete
  • Figure 16 illustrates the bulk bag 50 after the discharge of the meat product MP from the bulk bag has been completed.
  • the liner 84 is completely turned inside out with the skirt 86 now positioned on the outside of the liner proper.
  • the liner 100 comprises a length of tubular plastic film 102 which may,be formed from conventional polymeric materials such as polyethylene.
  • a first seam 104 closes one end of the liner 102 in the manner of a trash bag.
  • the liner 104 is formed into a rectangular configuration whereupon seams 106 and 108 are formed at the same end of the liner 102 as the seam 104. In this manner the liner 100 is retained in a rectangular configuration having dimensions which approximate the interior dimensions of the bulk bag in which the liner 101 will be used.
  • the seams 104, 106, and 108 may comprise heat seals. Alternatively, the seams 104, 106, and 108 may be adhesively constructed. Other conventional techniques for seaming polymeric materials may also be utilized in the practice of the invention.
  • each tab 110 may be rolled or folded to provide additional tear resistance.
  • a bulk bag 120 comprising one or more side walls 122 and a bottom wall 124.
  • the side wall(s) 122 are joined to the bottom wall 124 by seams 126.
  • Figure 19 also shows the liner 100 shown in Figures 17 and 18 described hereinabove in conjunction therewith positioned in the bulk bag 120.
  • the tabs 110 extending from the opposite sides of the lower end of the liner 100 are positioned between the lower edges of the side wall(s) 122 and the lateral edges of the bottom wall 124.
  • the seams 126 extend through the tabs 110 to secure the liner 100 within the bulk bag 120.
  • the distal ends of the tabs 110 may be rolled or folded to provide additional tear strength.
  • the bulk bag 120 having the liner 110 secured therein is used to receive, transport, and discharge meat products.
  • meat products are received in the liner 100 with the bulk bag 120 oriented as shown in Figure 19 .
  • the meat products received within the bulk bag 120 are discharged from the liner 100 thereof by inverting the bulk bag 120 as shown in Figure 20 .
  • the sticky nature of the meat products causes the liner 100 to move downwardly ( Figure 20 ) relative to the bulk bag 120 as the meat products are discharged therefrom.
  • the tabs 110 at the closed end of the liner 100 allow the liner 100 to move down a limited amount and then prevent further limited movement.
  • the abrupt stoppage of the downward movement of the liner 110 which is caused by the sewing the tabs 110 of the liner 100 into the seams joining the side wall(s) and the bottom wall of the bulk bag 120 causes the meat products to disengage from the liner 100 and fully discharge from the bulk bag 120.
