[0001] Cross - Reference to Related Applications This application claims the benefit of U.S. Patent Application No. 16 / 268,985, filed on February 6, 2019, which is a continuation - in - part of U.S. Patent Application No. 15 / 785,551, filed on October 17, 2017, which claims the benefit of U.S. Provisional Patent Application No. 62 / 447,129, filed on January 17, 2017. The entire disclosures of such applications are incorporated herein by reference.

[0002] Generally, the present invention relates to a hermetic seal assembly for a bag or flexible container.

Background Art

[0003] Generally, the use of large fabric bags, commonly known as flexible intermediate bulk containers (FIBCs) or simply bulk bags, has become widespread for transporting large quantities of materials (such as powdered substances, granular substances, liquids, etc.). Bulk bags can be lifted, moved, or transported by forklifts and other material handling equipment having hooks or tires. Usually, the fabric for bulk bags may use natural fibers, but is woven from strong tape - like synthetic resin fibers (such as polypropylene among others). Flexible intermediate bulk containers are widely used for containing, storing, transporting, and discharging all kinds of flowable materials.

[0004] Bulk bags may also be made to include an inner layer to prevent air intrusion or exposure to ambient humidity conditions. In many cases, a foil laminate can be included as an inner layer to limit moisture absorption. For example, bulk bags can contain flux materials that are prone to moisture absorption and can introduce diffusible hydrogen in weld metals. Bulk bags having an inner layer of foil laminate can limit exposure to moisture, but the effectiveness of the foil laminate decreases when the bulk bag is opened.

[0005] Therefore, improved bulk bag assemblies, systems, or techniques are needed to address these concerns. [Overview of the Initiative] [Means for solving the problem]

[0006] According to one embodiment of the present invention, a seal assembly system for a bulk bag is provided. The seal assembly is a bag for storing material and may include a bag with an opening. The bag includes an inner layer and an outer layer, where the inner layer is a foil laminate and the outer layer is a ribbon woven structure made of polypropylene. The flange has an upper end, an opposing lower end, and an inner wall defining a passage extending between the upper and lower ends. The flange may include a rim on the upper end and a web on the lower end, where the rim is on the outer circumference of the upper end and the web extends outward from the lower end and substantially parallel to it. The web of the flange is integrated with the inner and outer layers at the opening. A lid may be provided, which is releasably attached to the rim of the flange and configured to provide a hermetic seal at the opening. The lid may include a sampling port and a removable cap configured to seal the sampling port when attached to the sampling port and to provide access to the material when the lid is removed from the sampling port while attached to the rim of the flange.

[0007] According to one embodiment of the present invention, a bulk bag is provided. The bag has a cubic shape configured to hold a certain volume of material, and the bag has a front, a back opposite the front, a left side, a right side opposite the left side, a top, and a bottom opposite the top.

[0019] Figures 1-4 and 12-18 show a hermetic seal assembly 100 including a flange 102 and a lid 104. The flange 102 may include an upper end 106 and an opposing lower end 108. The flange 102 may include a passage 103 (shown in Figure 12) between the upper end 106 and the lower end 108. The flange 102 may be used in conjunction with a hermetic seal assembly for a bag, and the flange 102 may be attached to the opening of the bag or positioned around the opening end of the bag. The lid 104 is releasably coupled to the flange 102, where the lid 104 may include a top surface 118, a bottom surface 120, a side wall between the top and bottom surfaces, and an overhang 122 on the outer circumference of the lid 104. In one embodiment, the lid 104 may include a locking mechanism that can be removed from the flange 102 over a first opening of the lid 104.

[0020] The flange 102 may include an inner wall 124 and an outer wall 126. In one embodiment, the shape of the flange 102 and the lid 104 may be circular. The shape of the flange 102 and the lid 104 may be selected by appropriate technical judgment, and it should be recognized that the shape of the flange 102 and / or the lid 104 does not limit the invention of the subject matter. The flange 102 may include a rim 110 at the upper end 106, where the rim 110 is configured to engage with a gap 128 on the bottom surface of the lid 104. The outer wall 126 of the flange 102 may further include a web 111 used to be integrated or joined in part of the bag or at least one of the layers of the bag. In particular, the opening of the bag may include an outer perimeter, where the web 111 is heat-welded such that the outer perimeter of the web 111 aligns with the outer perimeter of the opening of the bag. The web 111 may include a first portion 114 for rigidity and a second portion 116 which, during heat welding, integrates with at least one of the bag or one or more bag layers (e.g., an inner layer, an outer layer, an additional layer, or a combination thereof). It should be noted that the first portion 114 has a first thickness and the second portion 116 has a second thickness, where the first thickness is greater than the second thickness.

[0021] The flange 102 may further include support ribs 112 located on the outer wall 126 of the flange 102, between the edge 110 and the web 111. The support ribs 112 may, among other things, be used to provide support for the hermetic seal assembly and / or the bag during filling, refilling, emptying, accessing, and cleaning the contents of the bag. Furthermore, a portion of the bag may be integrated with or bonded to the flange 102 on the outer wall 126 at a position between the support ribs 112 and the lower end 108 or the web 111.

[0022] In one embodiment, the flange 102 can be integrated with the opening of the bag (discussed in more detail below and shown at least in Figure 8). In particular, the flange 102 may be integrated with or bonded to the bag or at least one of the one or more layers of the bag, and the outer circumference of the lower end 108 of the flange 102 is integrated with the outer circumference of the opening of the bag. It should be noted that the flange 102 may be bonded to a part of the bag or a part of the opening of the bag. In another embodiment, the flange 102 may be positioned around the opening end of the bag, and the bag is folded outward over the flange 102, where the lid 104 presses and seals the folded portion of the bag between the lid 104 and the edge 110 of the flange 102 (discussed below and shown at least in Figures 9-11). In such an embodiment, a part of the opening end of the bag may be integrated with or bonded to a part of the flange. Continuing with such an embodiment, the part of the bag where the opening is located may be positioned through a passage 103. A portion of the bag passing through the flange 102 may be turned inside out (for example, folded over) on top of the flange 102, and the lid 104 may be releasably attached to the flange 102 such that the bag is sandwiched between the lid 104 and the flange while the opening is closed.

[0023] As discussed above, the hermetic seal assembly 100 may include a flange 102 and a lid 104, each having a shape and dimensions such that the lid 104 can be releasably coupled to the flange 102. In one embodiment, the flange 102 may have an inner diameter of approximately 10 to 14 inches. Furthermore, the height of the flange 102 (e.g., between the upper end 106 and the lower end 108) may be approximately 1 to 5 inches. The web 111 may have an outer width from the outer wall 126 of approximately 1 to 5 inches. Furthermore, the first thickness 114 of the web 111 may be approximately 1 / 8 inch, and the second thickness 116 may be 0.015 inches. However, it should be recognized that the diameter, height, shape, and / or size of the flange or any component of the hermetic seal assembly (e.g., lid, web, etc.) may be selected by appropriate technical judgment without departing from the scope of application of the subject invention.

[0024] In one embodiment, the web 111 can be inserted between the inner layer and the outer layer of the bag, where the web is integrated with a portion of the inner or outer layer. In another embodiment, the inner and outer layers are integrated together, and the bottom surface of the web 111 may be integrated with or joined to a portion of the flange 102. In yet another embodiment, the inner and outer layers are integrated together, and the top surface of the web 111 may be integrated with or joined to a portion of the flange 102.

[0025] Figure 2 shows a lid 104 that is attached to or releasably coupled to the flange 102. The lid 104 may include a top surface 118, a bottom surface 120, and side walls between them, where the bottom surface 120 includes a gap 128 configured to be received by a portion of the edge 110 on the flange 102. The gap 128 may be positioned on the bottom surface 120 of the lid 104, where it should be noted that the gap 128 and the edge 110 utilize tongue and groove joints. The lid 104 may be configured to be releasably coupled to the flange 102, and such coupling may be selected by appropriate technical judgment without departing from the scope of application of the subject invention. Not limited to, but as an example, the lid 104 may be coupled to the flange 102 by at least one of several types, including male-female fittings, screw connections, press-fit connections, and tongue and groove joints.

[0026] Figure 3 shows a perspective view of an embodiment of a hermetic seal assembly 300 including a flange 302 and a lid 304, which are attached to the opening end of a bag by inserting the flange 302 into the opening end of the bag, folding the end around the flange 302, and then using the lid 304 to press a portion of the bag against the upper end of the flange 302. Figure 4 shows a bottom perspective view of the hermetic seal assembly 300. The flange 302 may include an upper end 306 and an opposing lower end 308. The flange 302 may include a passage 303 between the upper end 306 and the lower end 308. The flange 302 may be used in conjunction with a hermetic seal assembly for a bag in which a portion of the bag is positioned through the passage 303 of the flange 302. The lid 304 is releasably coupled to the flange 302. In one embodiment, the lid 304 may include a locking mechanism that can be removed from the flange 302 over a first opening of the lid 304.

[0027] The flange 302 may include an inner wall 324 and an outer wall 326. In one embodiment, the shape of the flange 302 and the lid 304 may be circular. The shape of the flange 302 and the lid 304 may be selected by appropriate technical judgment, and it should be recognized that the shape of the flange 302 and / or the lid 304 does not limit the invention of the subject. The flange 302 may include an edge 310 at the upper end 306, where the edge 310 is configured to engage with a gap or rim on the bottom surface of the lid 304.

[0028] The flange 302 may further include a support rib 312 located on the outer wall 326 of the flange 302, between the edge 310 and the lower end 308. The support rib 312 may, among other things, be used to provide support for the hermetic seal assembly and / or the bag during filling, refilling, emptying, accessing, and cleaning the contents of the bag.

[0029] It should be noted that the cover 104 may be used together with the flange 102 or the flange 302. In another embodiment, it should be noted that the cover 304 may be used together with the flange 302 or the flange 102. In other words, the cover may be general-purpose or specific to one embodiment of the flange of the hermetic seal assembly.

[0030] Figure 5 shows one embodiment of the ribbon-woven bag 500. The bag 500 may be a ribbon-woven polypropylene bag structure that can safely contain all standard site waste within a ribbon-woven bag, and therefore the bag may be a disposable bag that is folded on-site, then opened, filled, and provided. Once filled, the bag 500 can be lifted by its top and transported to a waste disposal site. The bag 500 may have a side 502 with woven ribbons 504 running longitudinally and ribbons 506 running transversely. The bag 500 may include a closed end 510 and an open end 508. In one embodiment, the closed end 510 may be folded in itself as shown and sewn to the bottom of the bag via a seam 512 to complete the bag 500. The bag 500 may include an open end 508, a closed end 510 opposite it, a side 502, a back (opposite the front 502), a left side, and a right side. Bag 500 can accommodate or store a certain volume. As discussed above, bag 500 can include one or more layers. For example, bag 500 may include a sealed inner layer and an outer layer outside the inner layer, where the outer layer is ribbon-woven and has side walls (e.g., front, back, left, right) and an open end 508 and a closed end 510. This is further illustrated in Figures 19-21.

[0031] The shape of the bag 500 may be selected by appropriate technical judgment without departing from the scope of application of the subject invention, wherein the shape is configured to store or contain a certain volume of material. In one embodiment, the shape of the bag 500 may be cubic, having a front, a back opposite the front, a left side, a right side opposite the left side, a top, and a bottom opposite the top. In one embodiment, the bag 500 may include at least one opening that allows access to the inside of the bag 500. In another embodiment, the bag 500 may include an open end, wherein at least one of the front, back, left side, right side, top, or bottom is open.

[0032] Looking at Figure 6, a portion of the ribbon weave 600 for bag 500 is shown. In one embodiment, the width of the ribbon may be between 2 and 8 millimeters, but the width may be selected by appropriate technical judgment based on at least the material to be contained / stored in the bag. For example, it should be recognized that the denser the weave, i.e., the narrower the ribbon, the stronger the physical strength characteristics of the bag. The use of a wider ribbon can be interpreted as involving a looser weave, and therefore the bag may be lighter than one with a denser weave.

[0033] Looking at Figures 9, 10, and 11, we see that the flange 302 and lid 304 are used with the bag 500. The flange 302 and lid 304 can be used with the bag 500, with the opening end 508 of the bag 500 being placed through the flange 302, and in particular, the opening end 508 being inserted into the passage 303 (shown in Figure 3). A portion of the opening end 508 of the bag 500 is inserted through the upper end 306 and spreads out in a fan shape around the edge 310 of the flange 302. The lid 304 is placed on the flange 302 and can sandwich the outer circumference of the opening of the bag 500 between the lid 304 and the edge 310 of the flange 302. In particular, the edge 310 abuts against a portion of the outer layer 501 of the bag 500 (which is folded over by the flange 302), and the lid 304 abuts against the inner layer 503 of the bag 500 (shown in Figures 10 and 11). This connection allows the flange 302 and the lid 304 to provide a hermetic seal to the opening of the bag 500, where the lid 304 is resealable and resealable repeatedly. The flange 302 and the lid 304 can be used with bags having an opening (such as an opening 508), and can be applied to and / or used with bags without any structural changes or modifications to the bags.

[0034] Looking at Figure 7, the bag 700 is shown in a perspective view. The bag 700 can typically be shipped and transported on a pallet 702. The bag 700 may include one or more loops 704 near the top surface 706. For example, one or more loops 704 can facilitate moving the bag 700 to different locations and from there. The bag 700 may include side walls 708 (e.g., front, back, left, right). The bag 700 may further include a top surface and an opposite bottom surface, where the top surface may include an opening. In another embodiment, the bag 700 may include an open end on the top surface, and a flange 302 and a lid 304 can be utilized to provide a hermetic seal.

[0035] Figure 8 shows a flange 102 integrated with the bag 700, where the lid 104 is shown attached to the flange providing a hermetic seal. In particular, although the flange 102 is integrated with the top surface of the bag 700, it should be recognized that the flange 102 can be integrated with any side or location of the bag 700. For example, the hermetic seal assembly (e.g., flange 102, lid 104) may be on the side wall of the bag 700 or on the bottom surface of the bag 700.

[0036] Figures 12-15 show the flange 102. In particular, Figure 12 is a perspective view of the flange 102. Figure 13 shows a top view of the flange 102 of the hermetic seal assembly. Figure 14 shows a bottom view of the flange 102 of the hermetic seal assembly. Figure 15 shows a front view of the flange 102 of the hermetic seal assembly, where the rear view, left side view, and right side view are mirror images thereof.

[0037] Figures 16-18 show lids used with the hermetic seal assembly according to the subject invention. Figure 16 is a perspective view of the lid used with the hermetic seal assembly. Figure 17 shows a bottom view of the lid of the hermetic seal assembly. Figure 18 shows a top view of the lid of the hermetic seal assembly.

[0038] As discussed above, a portion of the flange 102 (shown in Figure 1) may be integrated with or bonded to a portion of the bag. In another embodiment, a portion of the flange 302 (shown in Figure 3) may be integrated with or bonded to a portion of the bag. It should be recognized that integration or bonding may be selected by appropriate technical judgment without departing from the scope of application of the subject invention. Not limited to, but as an example, integration of a portion of the flange to a portion of the bag may be by hot plate welding, flat plate welding, impulse welding, hot rod welding, weaving of a portion of the bag and a portion of the flange, insertion of a portion of the flange between one or more layers of the bag, melting of a portion of the bag to the flange, melting of a portion of the flange to the bag, or a combination thereof, but is not limited to these. In another embodiment, a portion of the flange may be bonded to a portion of the bag, where such bond may be by adhesive, tape fastening, gluing, bolting, riveting, or a combination thereof, but is not limited to these.

[0039] In yet another embodiment, the flange 302 may be releasedly bonded to the outer layer, i.e., outer layer, of the bag after being inserted into the flange 302 through the opening. One or more layers of the bag may be integrated with or bonded to at least one of the outer wall 326 of the flange 302, the inner wall 324 of the flange 302, the edge 310, the lower end 308, the support rib 312, or a combination thereof.

[0040] In one embodiment, the open end of the bag may include a compression member 1914 to facilitate connection between the bag and the flange 302. For example, the compression member 1914 may be positioned to maintain force such that the open end of the bag is inserted through the flange 302 and folded back to the edge 310 of the flange, with the folded portion of the bag being joined to a portion of the flange 302. It should be noted that the compression member 1914 may be integrated with the open end of the bag, woven into it, or be a separate component that is not woven in and is not part of the bag. The compression member 1914 can apply force to crush a portion of the bag and join it to a portion of the flange 302.

[0041] Looking at Figures 19-21, we see a hermetic seal assembly system. Figure 19 shows a portion of a bag 1900, where the bag has a cubic shape (e.g., bottom, left side, right side, front, back, and top) with an opening at the top. In Figure 19, the bag is shown having an outer layer 1902 and an inner layer 1904. Not limited to, but as an example, the inner layer 1904 may be a foil laminate and the outer layer 1902 may be a ribbon woven polypropylene structure. It should be recognized that the bag 1900 may include one or more layers, and the outer layer 1902 and inner layer 1904 are not limited to the subject invention. Furthermore, the outer layer 1902 may be made from a first material, and the inner layer 1904 may be made from a second material, where the first material may be selected by appropriate technical judgment to provide the bag with structural strength, integrity, and durability, and the second material may be selected by appropriate technical judgment to prevent air from entering the inner layer 1904 or from contaminating the material stored or contained in the inner layer 1904. For example, the outer layer 1902 may be a ribbon weave having one or more materials in the form of ribbons or fibers. As another example, the inner layer 1904 may be plastic or other airtight material.

[0042] The inner layer 1904 may be constructed to be an airtight and / or hermetic seal for the bag 1900 that does not allow exposure of the contents of the inner layer 1904. The inner layer 1904 may be constructed from one or more sheets of material and joined together to form a shape having a volume for storing material. Not limited to, but as an example, the shape of the inner layer 1904 of the bag may be a cube, formed from six sheets of material joined together at seams so that the cubes form a cubic shape. As considered, the inner layer 1904 may include an opening that is sealed but can be opened or broken if the contents of the bag are usable. The outer layer 1902 may include an outer and inner lining, where it should be recognized that the inner lining abuts against the outer lining of the inner layer 1904 and the outer lining is exposed to the outer components of the bag. Furthermore, the inner layer 1904 may include an outer and inner lining, where it should be recognized that the inner lining abuts against the material stored therein and the outer lining abuts against the inner lining of the outer layer 1902. If the additional layer is included in the bag 1900, the additional layer may be positioned between the outer layer 1902 and the inner layer 1904.

[0043] Figure 19 shows a bag 1900 in which the outer layer 1902 has been removed from the top surface of the bag, exposing the inner layer 1904 and the opening 1908. In one embodiment, the inner layer 1904 is fabricated with seams to form the shape of the bag 1900, such that the opening 1908 is positioned on the top surface and centered on the top surface of the bag 1900. The opening 1908 may be formed from the inner layer 1904 to form the neck portion 1906. It should be noted that the outer layer 1902 surrounds the inner layer 1904 and has an opening corresponding to the opening 1908, and furthermore, the outer layer 1902 is partially shown to show the inner layer 1904.

[0044] Figure 20 shows a bag 1900 with the neck portion of the folded outer layer 1902 and inner layer 1904. Figure 20 shows a bag 1900 having an outer layer 1902 and an inner layer 1904, both of which are folded to create an outer layer fold 1912 and an inner layer fold 1910. The opening 1908 can be further exposed and the size of the neck portion 1906 can be reduced by rolling or folding the inner layer 1904 and the outer layer 1902. In one embodiment, the inner layer 1904 may be rolled or folded separately from the outer layer 1902 (as shown in Figure 20). In another embodiment, the outer layer 1902 and the inner layer 1904 may be folded or rolled together (as shown in Figure 21). In one embodiment, the flange 302 is positioned over the opening 1908, allowing the rolled or folded portion of one or more layers to be positioned on the outer wall 326 of the flange 302, where the edge 310 of the flange 302 abuts against at least one of the outer casings of the inner layer 1904 or the outer casing of the outer layer 1902. For example, if the outer layer 1902 and the inner layer 1904 are folded or rolled together over the edge 310 of the flange 302, the edge 310 abuts against the outer casing of the outer layer 1902. In another embodiment, if the inner layer 1904 is folded or rolled separately over the edge 310 of the flange 302, the edge 310 abuts against the outer casing of the inner layer 1904. The flange 302 can be fitted into the opening, allowing the lid 304 to connect with the flange, and the number of folds or rolls may be selected by appropriate technical judgment to reduce the neck portion 1906 so that such connection sandwiches together the layers (one or more) of the bag. It should be noted that any excess material of the bag from the folds or rolls may be removed or cut off from the bag 1900.

[0045] Figure 21 shows a flange 302 coupled to folded layers (e.g., outer layer 1902, inner layer 1904), where the coupling is such that the flange 302 is positioned over the opening 1908 and the folded layers are positioned on the outer surface 326 of the flange 302. The flange 302 may be attached to or coupled to the bag 1900 at the position where the layers are folded and at the opening 1908. The coupling may be such that the outer layer 1902 and inner layer 1904 are folded over the edge 310, with the outer layer 1902 in contact with the edge 310 and the inner layer 1904 exposed to the outside of the bag 1900. A lid 304 is attached to the edge 310 of the flange so that the layers of the bag can be sandwiched between the lid 304 and the edge 310 of the flange 302. The compression member 1914 may further be positioned around the flange 302 and the folded layer to press the folded layer against the outer wall 326. It should be noted that the compression member 1914 may be, among many others, a rubber material, a polymer, a synthetic material, a natural material, a clamp, a bungee cord, a rope, a string, a ratchet strap, a tie-down, a shrink-wrapped plastic member, or a rubber band.

[0046] In one embodiment, the flange has a first shape having a first size, and the opening of the bag has a first shape having a second size, where the first size is larger than the second size. In one embodiment, the web extends outward from the lower end. In one embodiment, the web has a first thickness and a second thickness, where the first thickness is thicker than the second thickness and is positioned closer to the lower end compared to the second thickness. In one embodiment, a portion of the web is integrated between one or more layers of the bag. In one embodiment, a portion of the web is integrated with the inner layer of the bag. In one embodiment, a portion of the web is bonded to the outer layer, and the outer layer is bonded to the inner layer. In one embodiment, a portion of the web is bonded to the inner layer of the bag. In one embodiment, the seal assembly further includes heat welding to secure a portion of the flange to a portion of the bag. In one embodiment, the seal assembly further includes support ribs on the outer wall of the flange between the edge and the web.

[0047] Now, looking at Figure 22, we see the lid 2004. The lid 2004 may include some or all of the same components and features as those described above with respect to the lid 104 or 304. For example, the lid 2004 may be releasably coupled to the flange 102, where the lid 2004 may include a top surface 2018, a bottom surface (not shown), a side wall between the top surface 2018 and the bottom surface, and an overhang 2022 on the outer circumference of the lid 2004. In one embodiment, the lid 2004 may include a locking mechanism that can be removed from the flange 102 over a first opening of the lid 2004.

[0048] In addition, the lid 2004 may further include a sample collection port 2006 and a corresponding cap. The sample collection port 2006 allows the user to insert a sampling device, such as a sample collector, into the sample collection port 2006 to obtain a sample from the contents of the bag 1900. By using the sample collection port 2006, the user does not need to remove the lid 2004 from the flange / bag connection to obtain a sample. Therefore, the seal created between the lid 2004, flange 102, and bag 1900 remains intact, preventing damage caused by friction on the bag 1900 during removal and replacement of the lid 2004. The sample collection port 2006 also allows for periodic monitoring of the contents of the bag 1900 over a period of time without the risk of damaging the bag 1900 at the joint where the lid 2004 connects to the flange 102. Furthermore, the sample collection port 2006 may allow the user to ventilate the bag 1900 without having to remove the lid 2004 from the flange 102 and the bag 1900.

[0049] The sample collection port 2006 can be molded onto the upper surface of the lid 2004. The cap corresponds to the opening of the sample collection port 2006 and can seal the sample collection port 2006 when coupled with the opening. The cap 2008 may be, for example, a threaded cap, a plug 2008, or a latched cover, depending on the type of sample collection port 2006 used. In a particular embodiment, the cap forms a recess below the upper surface 2018 of the lid 2014 when coupled with the opening of the sample collection port 2006. In a particular embodiment, the seal 2010 can be placed on or attached to the cap such that part of the seal 2010 is attached to the cap and another part of the seal 2010 is attached to the upper surface 2018 of the lid 2004. In this way, the seal 2010 breaks when the user removes the cap from the sample collection port 2006. The broken seal 2010 can indicate that the cap has been removed. It should be recognized that the seal 2010 may be installed by the initial manufacturer or distributor, and that the likelihood of the seal 2010 being damaged when the cap is removed may be improved by tamper-evident treatment of the seal 2010 or by any available means of choice. The top surface 2018 of the lid 2004 may also include a label 2012 which may include information such as instructions on how to take a sample of the contents of bag 1900 through the sampling port 2006, how to ventilate bag 1900 through the sampling port 2006, and / or information about the contents of bag 1900, including identification information or material safety information.

[0050] As an example, and not an limitation, the sample collection port 2006 may be circular and / or have a diameter of 70 mm. However, it should be recognized that the sample collection port 2006 may have any shape or size selected using appropriate technical judgment. In a particular embodiment, the sample collection port 2006 may have a diameter smaller than the diameter of the top surface 2018 of the lid 2004. In one embodiment, the sample collection port 2006 is a threaded port, such as a serrated threaded port. In this embodiment, the cap is a corresponding threaded cap that can be used by the user to seal the sample collection port 2006 by screwing the cap onto the threads of the sample collection port 2006. To remove the threaded cap and access the sample collection port 2006, the user can loosen the threaded cap from the sample collection port 2006. In another embodiment, the sample collection port 2006 may have a plug-in configuration. In this embodiment, the cap is a corresponding plug 2008 (e.g., a toning plug) that can be used by a user to seal the sample collection port 2006 by inserting the plug 2008 into the sample collection port 2006. The plug 2008 can be sized such that it is held in place within the sample collection port 2006 by friction fit or snap fit. The plug 2008 may include a ring 2014 attached to the top of the plug 2008. The ring 2014 allows the user to insert their finger into the ring 2014 so that the user can pull the plug 2008 out of the sample collection port 2006, as shown in Figure 23. In a particular embodiment, a seal 2010 can be bonded to the top of the ring 2014 such that the seal 2010 would need to break in response to a user accessing the ring 2014 and removing the plug 2008 from the sample collection port 2006.

[0051] Now, looking at Figure 24, we see the sample collection procedure. Once the cap (e.g., plug 2008) is removed from the sample collection port 2006, the user can access the contents of bag 1900 through the opened sample collection port 2006. For example, the user can insert a sample collector 2024 into bag 1900 through the sample collection port 2006. In this way, the user can obtain a sample of the contents of bag 1900 through the sample collection port 2006, thereby eliminating the need to remove the flange 102 and the lid 2004 from bag 1900 to collect a sample. In one embodiment, the user can obtain a sample of the contents of bag 1900 by using the sample collector 2024 to collect a multilayer cross-sectional sample from the contents. Once the desired sample has been collected, the user can remove the sample collector 2024 from the sample collection port 2006 and reinsert the cap (e.g., plug 2008) into the sample collection port 2006.

[0052] Now, looking at Figure 25, we see the ventilation procedure. In addition to providing access to the contents of bag 1900, the sample port 2006 can also allow the user to ventilate bag 1900. If the lid 2004 or cap is removed, bag 1900 should be ventilated to remove all or most of the air contained within bag 1900 before anything is placed on top of it. With the cap removed, the user can compress the top of bag 1900 to force air 2026 out of the bag through the open sample port 2006. After ventilating bag 1900, the user can then reattach the cap to the sample port 2006 (for example, by screwing it onto a threaded cap or reinserting the plug 2008).

[0053] The aforementioned systems and components (for example, among many, the hermetic seal assembly system 100, the hermetic seal assembly 300, the flange 102, the lid 104, the flange 302, the lid 304, the lid 2004, the bag 500, the bag 700, the bag 1900, the compression member 1914), etc., have been described in relation to the interactions between some of the components and / or constituent elements.
