Abstract
Description
- The present invention is concerned with container assemblies for a variety of materials, especially particulate solid materials such as contaminated earth. More particularly, the invention is concerned with such container assemblies which may be flexible intermediate bulk containers (FIBCs), characterized by the provision of a central flexible bag for the materials, with a surrounding collection skirt allowing easy bag filling and closure of the assemblies.
- A flexible intermediate bulk container, also referred to as a “bulk bag” or a “big bag,” is an industrial container made of flexible material that is designed for storing and transporting dry, flowable products, such as earth, sand, fertilizer, and plastic granules. A variety of FIBC designs have been proposed in the past, which are typically differentiated by the bag bottom wall, which may be plain or equipped with various types of closures or discharge spouts. In general, these bags are used by deployment thereof in an open-top unfilled condition, followed by depositing the desired material into the bag structure. These types of designs suffer from the fact that extraneous material will often flow past the bag opening and collect as spillage on the ground or other support surface. This is particularly troublesome where contaminated materials, such as soils, are to be bagged and transferred.
- U.S. Pat. No. 5,967,579 discloses an “industrial diaper” for use in controlling spills from damaged FIBCs. As illustrated in
FIG. 1 of the drawings, a cruciform-shaped sheet having acentral opening 16 and four outwardly extendingpanels 14 is illustrated. As seen inFIGS. 3 and 4 , the sheet is laid on the ground or other surface, and a damaged FIBC is placed thereon, with theoutlet 38 of the FIBC extending through the opening 16. Thereupon, the fourpanels 14 are drawn upwardly and attached together. - U.S. Pat. No. 7,736,057 discloses a leaf bag having a standard upright rectangular bag 102 with a funnel construction extending upwardly and outwardly from the upper margins of the bag. As disclosed, the funnel is designed to facilitate loading of the bag 102. However, the bag 102 is not collapsible and the funnel structure is not designed to lay flat on the ground.
- U.S. Pat. No. 7,219,705 discloses a leaf bag system for use with a receptacle, such as a waste can. The '705 bag provides a funnel-like structure which can be secured to the upper end of the can to allow filling thereof with leaves.

- The present invention overcomes the problems outlined above and provides container assemblies for materials generally comprising a flexible bag including an open top and presenting a periphery, sidewall structure, and a bottom wall. The bag is movable between a collapsed position when unfilled with material, and an expanded position when material is placed therein. The overall assemblies also include a flexible collection skirt secured to the bag adjacent the open top thereof and extending outwardly therefrom and around the periphery of the open top. The collection skirt has an outer margin and gathering apparatus at spaced locations adjacent the outer margin in order to permit gathering of the skirt during filling of the bag with material and consequent movement of the bag to the expanded position thereof.
- In order to provide adequate protection against material spillage, the area of the surrounding skirt is greater than the area of the open top of the bag. In an embodiment, the outer margin of the skirt may be substantially circular, but this is in no way required; indeed, the skirt can assume any desired shape so long as it surrounds the open top of the bag and provides adequate area for preventing material spillage. Gathering apparatus is also provided for the skirt, which may be in the form of a plurality of circumferentially spaced apart lifting loops secured to the outer margin of the skirt; alternately, a drawstring-type gathering apparatus may be used.
- In addition, the central bag is advantageously equipped with a plurality of exterior lifting points located about the periphery of the top of the bag. In order to accommodate the bag, the skirt has a central opening in the shape of the bag and a plurality of connection segments adjacent this central opening in order to permit attachment of the bag top to these segments.
- The bag and skirt are preferably formed of flexible synthetic resin material, but other types of flexible material, such as canvas, could be used.
- In the use of the container assemblies of the invention, the latter are deployed on the ground or other support surface by maintaining the bag in a collapsed position with the skirt extending outwardly therefrom in an essentially lay-flat configuration. Thereupon, the material to be bagged is deposited in the central region of the assembly over the open top of the bag and, as necessary, on the skirt near the bag. Next, the skirt gathering apparatus is used to lift the outer margin of the skirt in order to elevate the assembly. This causes flow of the material into the bag in order to fill it, with the gathered skirt above the bag opening. This gathered skirt can then be tied off or otherwise closed to create a duffel top. The now-exposed bag lifting points are then used to lift the filled and closed container for transport of the collected material.

FIG. 10 is a top perspective view similar to that ofFIG. 2 , illustrating another embodiment of the invention making use of a drawstring-type peripheral gathering apparatus. - While the drawings do not necessarily provide exact dimensions or tolerances for the illustrated components or structures,
FIGS. 1-10 are to scale with respect to the relationships between the components of the structures illustrated therein. - Turning now to
FIGS. 1-4 , a FIBC-type container assembly 10 is depicted, which generally includes a centralflexible bag 12 and a surrounding,flexible skirt 14, the latter equipped with gatheringapparatus 16 at spaced locations adjacent the outer margins of the skirt, and withlifting points 18 secured to the exterior ofbag 12 adjacent the upper margins thereof. Thebag 12 includes anopen top 20 presenting aperiphery 22, as well assidewall structure 24, and abottom wall 26. The bag is designed to move between a collapsed, folded-up configuration, illustrated inFIGS. 1-3 , and an expanded position shown inFIG. 4 . - In more detail, in the illustrated embodiment, the
bag 12 is of quadrate configuration in plan withfoldable sidewall structure 24 and aplanar bottom wall 26. As shown inFIGS. 1-3 , thebag 12 is initially in its folded-up configuration below theskirt 14. Of course, the bag may be of any other desired shape (e.g., cylindrical or octagonal), and the size thereof is limited only by design considerations for the intended use of theassembly 10. Thelifting points 18 are in the form of welded orsewn loops 28, which are secured to thesidewall structure 24 adjacent theopen top 20. - The
skirt 14 completely surrounds thebag 12, which is important for purposes to be described, and has acentral opening 29 for accommodating thebag 12. As depicted, thegathering apparatus 16 includes a series ofpickup loops 30 secured by welding or stitching to the outer margin of the skirt at circumferentially spaced locations. Again, while theskirt 14 is depicted as being substantially circular at its outer margin, any number of skirt shapes could be used. - In order to properly secure the
bag 12 toskirt 14, the latter is equipped with a series ofconnection segments 32 at the region of opening 29 (seeFIGS. 4 and 6 ). The segments 34 are attached by any convenient means to the upper margin ofsidewall structure 24, in order to afford a secure connection between thebag 12 and theskirt 14. - As illustrated in
FIG. 1 , during storage theassembly 10 is completely folded up, i.e., thebag 12 is in its collapsed position and theskirt 14 is folded over thebag 12. However, when it is desired to use theassembly 10, theskirt 14 is unfolded and laid upon the ground or other support surface, with thebag 12 still in its collapsed position (FIGS. 2-3 ).FIG. 6 illustrates a condition where aparticulate material 36, such as contaminated soil, is placed upon theassembly 10 over theopen top 20 ofbag 12 and, to the extent necessary, onto theskirt 14. Once the material is so placed, liftingcable grappling hooks 38 are coupled with theloops 30 and these are pulled upwardly. As this occurs, thebag 12 is deployed downwardly under the weight of thematerial 36, until thebag 24 is completely filled (FIG. 8 ), with any additional fill piled above the open top 20, but still within the confines of theskirt 14. Finally, theskirt 14, now in a drawn-together configuration, is closed using a tie or the like (FIG. 9 ). This exposes the lifting points 18 allowing further use of the grappling hooks to lift and convey the closed container assembly for disposal as necessary of thematerial 36. -
FIG. 10 depicts another embodiment of the invention in the form of anassembly 10 a, which is identical in many respects to theassembly 10. Accordingly, like reference numerals will be used to describe theassembly 10 a, with the addition of the letter identifier “a.” Specifically, theassembly 10 a has a central,flexible bag 12 a and a surroundingflexible skirt 14 a, the latter equipped withgathering apparatus 16 a, here including a peripheral, continuous drawstring in the form of acable 40, which is captively retained within apocket 42 extending about the outer margin ofskirt 14 a. As illustrated, thepocket 42 has a plurality ofopenings 44 formed therein which are circumferentially spaced about the pocket. Theopenings 44 allow access to thedrawstring cable 40 when it is desired to lift and elevate theskirt 14 a. For example, and as depicted inFIG. 8 ,cable grappling hooks 38 may be secured to thedrawstring cable 40 at theopenings 44. Elevation of thehooks 38 causes theskirt 14 a to be drawn upwardly into the general shape of a column, which can then be tied off as described. - In some instances, the flexible bags of the container assemblies of the invention may be equipped with waterproof liners, formed of an appropriate material, such as polyethylene, to prevent leakage of liquids.
