Second dust-entry port 39 is located between first dust-entry port 19 and rake-access inlet 16 as suggested in FIGS. 2 and 7.

Basin 28 includes a floor 280 and in series, first, second, third, and fourth side-wall panels 281, 282, 283, and 284 that cooperate (in an illustrative embodiment) to form endless side wall 285. Each of side-wall panels 281-284 is coupled to floor 280 along a floor seam 40 and to basin cover 32 along cover seam 34 to cause rake-access inlet 16 to lie above and in spaced-apart relation to floor 280 of basin 28 as suggested in FIGS. 2 and 7. Basin 28 is made of a flexible material in an illustrative embodiment.

In an illustrative embodiment, first side-wall panel 281 is coupled to one edge of basin cover 32 along a first portion 341 of cover seam 34 and second side-wall panel 282 is coupled to a second edge of basin cover 32 along a second portion 342 of cover seam 34 as suggested in FIG. 13. Third side-wall panel 283 is coupled to a third edge of basin cover 32 along a third portion 343 of cover seam 34 and fourth side-wall panel 294 is coupled to a fourth edge of basin cover 32 along a fourth portion 344 of cover seam 34.

Endless side wall 285 is arranged to interconnect floor 280 and the basin cover 32 and coupled to basin cover 32 at cover seam 34 as suggested in FIG. 1. Fourth side-wall panel 284 is coupled to first side-wall panel 281 as suggested in FIGS. 3 and 5. Each of first and third side-wall panels 281, 283 has a short width W1 as measured between adjacent second and fourth side-wall panels 282, 284 as suggested in FIG. 13. Each of second and fourth side-wall panels 282, 284 has a relatively longer long width W2 as measured between adjacent first and third side-wall panels 281, 283 as suggested in FIG. 13. Rake-access inlet 16 is formed along portion 341 of cover seam 34 located between basin cover 32 and first side-wall panel 281.

Rake-access inlet closure 20 is coupled to bag 12 as suggested in FIGS. 3 and 4. Rake-access inlet 20 is configured to provide means for opening rake-access inlet 16 while waste dust 20 is flowing into interior region 14 of bag 12 through first dust-entry port 19 to receive a waste-dust rake 26 in rake-access inlet 16 to allow technician 100 to move waste-dust rake 26 relative to bag 12 to level a heap of waste dust 24 that has accumulated in interior region 14 of bag 12 under first dust-entry port 19 formed in bag 12 and for selectively closing rake-access inlet 16 after removal of dust rake 26 from interior region 14 formed in the bag 12 to limit discharge of waste dust 24 from bag 12.

Rake-access inlet closure 20 includes a first zipper track 21 coupled to first side-wall panel 281 and arranged to border rake-access inlet 16, a second zipper track 22 coupled to basin cover 32 and arranged to border rake-access inlet 16, and a sliding piece 23 in an illustrative embodiment as suggested in FIGS. 1 and 2. Sliding piece 23 is coupled to each of first and second zipper tracks 21, 22 for movement relative to bag 12 along portion 341 of cover seam 34 in one direction D1 as suggested in FIG. 4 to mate first and second zipper tracks 21, 22 to close rake-access inlet 16 and in an opposite second direction D2 as suggested in FIG. 3 to unmate first and second zipper tracks 21, 22 to open rake-access inlet 16.

Bag 12 is configured to minimize the amount of waste dust 24 that is released into the air surrounding bag 12. Waste dust 24 enters interior region 14 of bag 12 through chutes 18, 38 (or any other suitable means). While in operation, the only access to waste dust 24 in interior region 14 is through an opened rake-access inlet 16. Rake-access inlet closure 20 can be operated by technician 100 to allow limited access to waste dust 24 in interior region 14 so that waste dust 24 can be raked using a dust rake 26 extending into interior region of bag 12 through an opened rake-access inlet 16.

As suggested in FIGS. 2 and 7, dust rake 26 includes a rake head 261 and a handle 262 coupled to rake head 261. Handle 262 is configured to provide means arranged to extend through rake-access inlet 16 for moving rake head 261 back and forth in interior region 14 to level a heap of waste dust 24 accumulated in interior region 14 while waste dust 24 is flowing into interior region 14 through (at least) first dust-entry port 19 and first and second zipper tracks 21, 22 are at least partly unmated to open rake-access inlet 16 as suggested in FIGS. 2, 7, and 8.

In use, on some occasions, a heap of waste dust 24 can form in interior region 14 of bag 12 under first dust-entry port 19 as suggested in FIG. 5. Technician 100 can use closure 20 to open rake-access inlet 16 as suggested in FIGS. 4, 7, and 8 while waste dust 24 is flowing from waste dust delivery system 11 into interior region 14 of bag 12. Closure 20 provides access to bag 12 while bag 12 is being filled. This permits technician 100 to insert dust rake 26 into bag 12 and rake and flatten a heap of waste dust 24 while waste dust 24 continues to flow into interior region 14 of bag 12. More capacity is created in bag 12 to allow interior region 14 to be filled to the top and thus maximize use of interior region 14 and fill capacity. Once bag 12 is full, chutes 18 and 38 are tied shut with durable polypropylene straps. Transport of a filled bag 12 to a remote bag-disposal site is facilitated by filling a bag 12 while it is located in a bag carrier 112 as suggested in FIG. 13.

In other illustrative embodiments, a rake-access inlet closure 220 in accordance with the present disclosure comprises a series of snaps located along rake-access inlet 16 as shown, for example, in FIGS. 11 and 12. These snaps can be opened and closed by technician 100 to open and close rake-access inlet 16.

A bag 212 is formed to include a rake-access inlet 16 as suggested in FIG. 11. Bag 212 is coupled to a rake-access inlet closure 220 in accordance with another embodiment of the present disclosure. Rake-access inlet closure 220 includes a separable retainer snap 223 coupled to a basin cover 232 and to first side-wall panel 281 to close the rake-access inlet 16 as suggested in FIG. 11. It is within the scope of this disclosure to use one or retainer snaps or other suitable fasteners to close rake-access inlet 16 temporarily.

Basin cover 232 includes a top wall 232T formed to include first dust-entry port 19 and a foldable flap 232F coupled to top wall 232T. Top wall 237 of basin cover 232 is coupled to first, second, third, and fourth side-wall panels 281, 282, 283, and 284 at cover seam 34. Retainer snap 223 includes a first snap element 221 coupled to first side-wall panel 281 and a second snap element 222 coupled to foldable flap 232F to move therewith relative to first side-wall panel 281 and configured to mate with first snap element 221 to retain foldable flap 232F in a position closing rake-access inlet 16.

A bag 312 is formed to include a rake-access inlet 16 as suggested in FIG. 12. Bag 312 includes a basin cover 332 including top wall 232T and a foldable flap 332F coupled to top wall 232T along portion 341 of cover seam 34. Separable retainer snap 223 is coupled to first side-wall panel 281 and foldable flap 332F. Foldable flap 332F has a first length L1 that is relatively greater than a second length L2 of foldable flap 232F as suggested in FIGS. 11 and 12.

Each of bags 12, 212, and 312 is made of a flexible material and is suitable for use in a flexible intermediate bulk container (FIBC) unit. Such units are configured to be collapsed and folded, when empty, to permit the volume of the unit to be reduced for easier handling and storage.

An FIBC unit typically includes a single access that permits the unit to be filled with waste material. Often this access point is positioned in a manner that causes material to accumulate in the unit in a way that does not fill the entire volume of the unit effectively. Waste materials stored and transported in FIBC units include granular materials formed as by-products of industrial processes. FIBC units capture dust, debris, and other waste material formed during industrial and manufacturing processes, e.g., casting of metals and milling and machining of wood, steel, ceramics, and other refractory materials

In illustrative embodiments, rake-access inlet 16, when opened, permits a technician, e.g., a mill worker, to insert a dust rake 26 such as a rake, hoe, or other leveling device into interior region 14 of bag 12, 212, or 312 while waste dust 14 is flowing into interior region 14. The technician may smooth, level, flatten, and otherwise arrange waste dust 24 in interior region 14 to use fully the capacity of bag 12, 212, or 312.

In illustrative embodiments, rake-access inlet 16 has a cross-sectional area that is sized to receive rake head 261 of dust rake 26 therein. Such area may be round-, oblong-, square-, or rectangle-shaped.

In illustrative embodiments, closure 20 and 220 is configured to limit access to interior region 14 via rake-access inlet 16. This, in turn, restricts flow of waste dust 24 that may be emitted from interior region 14 when interior region 14 is filled with waste dust 24.

In an illustrative embodiment, rake-access inlet closure 20 is configured to reduce the accessible portion of area of rake-access inlet 16 by at least about 50% when in its closed position. The closed position is the position where the least amount of material would be able to be emitted from container 100. Illustratively, but not necessarily, closure 20 includes a sealable device. Examples of sealable devices that are suited for use in closure 20 include, but are not limited to, zippers, snaps, buttons, hook-and-loop fasteners, and frictional-fit type fasteners (e.g., ZIPLOC® fasteners), among others. These may be installed monolithically with rake-access inlet 16, as illustrated in FIG. 1. In other illustrative embodiments, however, rake-access inlet closures in accordance with the present disclosure may be located remote from rake-access inlet 16. Such remote-type sealable devices may include flaps and/or other pieces of material that can be positioned and secured to reduce the accessible area of rake-access inlet 16 by at least about 50%. In still other embodiments a closure may be removably secured to the bag so as to permit it to be detached from the bag in order to expose all of, or a portion of rake-access inlet 16. These types of devices could then be secured to a bag with some type of fastener (e.g., snaps, buttons, hook-and-loop fasteners) in order to reduce the exposed portion of rake-access inlet 16 and restrict the number of particles emitted from the bag.
