Hermetic seal for foil-lined FIBC (bulk bag)

TECHNICAL FIELD

In general, the present invention relates to a hermetic seal assembly for a bag or flexible container.

BACKGROUND OF THE INVENTION

The use of large bags of fabric, commonly called flexible, intermediate bulk containers (FIBCs) or simply bulk bags, has become commonplace for transporting bulk quantities of materials (e.g., powdered materials, granular materials, liquids, etc.). Bulk bags can be lifted, moved, or transported by forklift trucks and other material handling equipment having hooks or tines. The cloth for the bulk bags is usually woven of strong, tape-like man-made plastic fibers (e.g., polypropylene, among others), though natural fibers can be employed. Flexible intermediate bulk containers have come into widespread use for receiving, storing, transporting, and discharging flowable materials of all types.

Bulk bags can also be fabricated to include an inner layer to prevent atmospheric infiltration or prevention of exposure to ambient humidity conditions. Often, a foil laminate can be included as an inner layer to limit moisture pickup. For example, a bulk bag can house a flux material that is susceptible to moisture pickup and can lead to diffusible hydrogen in the weld metal. Although the bulk bag having an inner layer of foil laminate can limit exposure to moisture, the foil laminate effectiveness is reduced upon opening of the bulk bag.

Accordingly, an improved bulk bag assembly, system, or methodology addressing these concerns is needed.

SUMMARY OF THE INVENTION

In accordance with an embodiment of the present invention, a seal assembly system for a bulk bag is provided. The seal assembly can include a bag that stores a material, the bag includes an opening. The bag includes an inner layer and an outer layer, wherein the inner layer is a foil laminate and the outer layer is a ribbon-woven structure made of polypropylene.

The inner layer 1904 can be created to be an airtight and/or hermetic seal for the bag 1900 which does not allow exposure of contents of the inner layer 1904. The inner layer 1904 can be created from one or more sheets of material and coupled together to create a shape having a volume that stores a material. By way of example and not limitation, the shape of the inner layer 1904 of the bag can be a cube such that the cube is formed with 6 (six) sheets of material that are coupled together at seams to form the cube-like shape. As discussed, the inner layer 1904 can include an opening that is hermetically sealed but can be opened or broken when contents of the bag are ready for use. It is to be appreciated that the outer layer 1902 can include an exterior and an interior, wherein the interior is in contact with exterior of the inner layer 1904 and the exterior is exposed to elements outside the bag. Further, it is to be appreciated that the inner layer 1904 can include an exterior and an interior, wherein the interior is in contact with the materials stored therein and the exterior is in contact with the interior of the outer layer 1902. If an additional layer is included with the bag 1900, the additional layer can be positioned in between the outer layer 1902 and the inner layer 1904.

FIG. 19 illustrates the bag 1900 with the outer layer 1902 removed on the top side of the bag to expose and illustrate the inner layer 1904 and an opening 1908. In an embodiment, the inner layer 1904 can be fabricated with seams to form the shape of the bag 1900 such that the opening 1908 is positioned on the top side of the bag 1900 and in the center of the top side. The opening 1908 can be formed from the inner layer 1904 which creates a neck 1906. It is to be appreciated that the outer layer 1902 surrounds the inner layer 1904 and would have an opening that corresponds to the opening 1908 yet the outer layer 1902 is partially shown in order to illustrate the inner layer 1902.

FIG. 20 illustrates a view of the bag 1900 and the neck of the outer layer 1902 and the inner layer 1904 folded. FIG. 20 illustrates the bag 1900 having the outer layer 1902 and the inner layer 1904, both are folded creating an outer layer fold 1912 and an inner layer fold 1910. The opening 1908 can be further exposed while reducing a size of the neck 1906 by rolling or folding the inner layer 1904 and the outer layer 1902. In an embodiment, the inner layer 1904 can be rolled or folded separately from the outer layer 1902 (as shown in FIG. 20). In another embodiment, the outer layer 1902 and the inner layer 1904 can be folded or rolled together (as shown in FIG. 21). In either embodiment, the collar 302 can be positioned over the opening 1908 to allow the rolled or folded portion of the layer(s) to be positioned on the external wall 326 of the collar 302, wherein the lip 310 of the collar 302 is in contact with at least one of an exterior of the inner layer 1904 or an exterior of the outer layer 1902. For example, if the outer layer 1902 and the inner layer 1904 are folded or rolled together over the lip 310 of the collar 302, the lip 310 is in contact with an exterior of the outer layer 1902. In another example, if the inner layer 1904 is folded or rolled separately over the lip 310 of the collar 302, the lip 310 will be in contact with an exterior of the inner layer 1904. The number of folds or rolls can be selected with sound engineering judgment so as to reduce the neck 1908 so the collar 302 can fit over the opening and allow the lid 304 to couple to the collar while such coupling pinches the layer(s) of the bag together. It is to be appreciated that excess material of the bag from folding or rolling can be removed or cut off from the bag 1900.

FIG. 21 illustrates the collar 302 coupled to the folded layers (e.g., the outer layer 1902, the inner layer 1904), wherein the coupling is such that the collar 302 is placed over the opening 1908 and the folded layers are placed on the exterior surface 324 of the collar 302. The collar 302 can be affixed or coupled to the bag 1900 at the position where the layers are folded and at the opening 1908. The coupling can be such that the outer layer 1902 and the inner layer 1904 are folded over the lip 310, the outer layer 1902 is in contact with the lip 310, and the inner layer 1904 is exposed to outside the bag 1900. The lid 304 can be affixed to the lip 310 of the collar to pinch the layers of the bag between the lid 304 and the lip 310 of the collar 302. The compression member 1914 can be further positioned around the collar 302 and the folded layers to press the folded layers against the external wall 326. It is to be appreciated that the compression member 1914 can be a rubber material, a polymer, a synthetic material, a natural material, a clamp, a bungie cord, a rope, a string, a ratchet straps, tie downs, a plastic member that is shrink wrapped, an elastic band, among others.

In an embodiment, the collar is a first shape having a first size and the opening of the bag is the first shape having a second size, wherein the first size is greater than the second size. In an embodiment, the web extending outwardly from the bottom end. In an embodiment, the web includes a first thickness and a second thickness, wherein the first thickness is greater than the second thickness and positioned proximate to the bottom end in comparison to the second thickness. In an embodiment, a portion of the web is integrated between one or more layers of the bag. In an embodiment, a portion of the web is integrated to the inner layer of the bag. In an embodiment, a portion of the web is coupled to the outer layer, and the outer layer is coupled to the inner layer. In an embodiment, a portion of the web is coupled to the inner layer of the bag. In an embodiment, the seal assembly further comprises a heat weld that secures a portion of the collar to a portion of the bag. In an embodiment, the seal assembly further comprises a support rib on an external wall of the collar in between the lip and the web.

Turning now to FIG. 22, a lid 2004 is shown. The lid 2004 can include some or all of the same components and features as described above with respect to lid 104 or 304. For example, the lid 2004 can be releaseably coupled to the collar 102, wherein the lid 2004 can include a top side 2018, a bottom side (not shown), a sidewall in between the top side 2018 and the bottom side, and an overhang 2022 on the perimeter of the lid 2004. In an embodiment, the lid 2004 can include a locking mechanism that can be removed on a first opening of the lid 2004 from the collar 102.

In addition, the lid 2004 can further include a sampling port 2006 and a corresponding cap. The sampling port 2006 allows a user to insert a sampling device such as a sampling thief into the sampling port 2006 to obtain a sample of the contents of the bag 1900. By using the sampling port 2006, the user does not need to remove the lid 2004 from the collar/bag connection to obtain the samples. Accordingly, the seal that is created between the lid 2004, the collar 102, and the bag 1900 remains intact and undisturbed, preventing wear and tear caused by friction on the bag 1900 during removal and replacement of the lid 2004. The sampling port 2006 allows for regular monitoring of the contents of the bag 1900 over time without the risk of damaging the bag 1900 at the location of the joint where the lid 2004 connects to the collar 102. Further, the sampling port 2006 can allow a user to vent the bag 1900 without needing to remove the lid 2004 from the collar 102 and bag 1900.

The sampling port 2006 can be molded into the top side of the lid 2004. A cap corresponds to an opening of the sampling port 2006 and can seal the sampling port 2006 when coupled with the opening. The cap 2008 can be, for example, a threaded cap, a plug 2008, a latched cover, among others, depending on the type of sampling port 2006 used. In certain embodiments, the cap is recessed below the top side 2018 of the lid 2014 when it is coupled with the opening of the sampling port 2006. In certain embodiments, a seal 2010 can be placed or adhered over the cap such that a portion of the seal 2010 is adhered to the cap and another portion of the seal 2010 is adhered to the top side 2018 of the lid 2004. In this manner, when a user removes the cap from the sampling port 2006, the seal 2010 will tear. A torn seal 2010 can provide an indication that the cap has been removed. It should be appreciated that the seal 2010 can be installed by an initial manufacturer or a distributor, and that any available means of tamper-evident treatment or selection of the seal 2010 can be used to improve the likelihood of the seal 2010 breaking upon cap removal. The top side 2018 of the lid 2004 can also include a label 2012 that can include information such as user instructions pertaining to sampling the bag 1900 contents through the sampling port 2006, venting the bag 1900 through the sampling port 2006, and/or information about the contents of the bag 1900 including identifying information or material safety information.

By way of example and not limitation, the sampling port 2006 can be circular and/or have a diameter of 70 mm. However, it should be appreciated that the sampling port 2006 can have any shape or size selected using sound engineering judgment. In certain embodiments, the sampling port 2006 can have a diameter that is smaller than the diameter of the top side 2018 of the lid 2004. In one embodiment, the sampling port 2006 is a threaded port, such as for example, a buttress-thread port. In this embodiment, the cap is a correspondingly threaded cap that a user can use to seal the sampling port 2006 by screwing the cap onto the sampling port 2006 threads. To remove the threaded cap to gain access to the sampling port 2006, a user can unscrew the threaded cap from the sampling port 2006. In another embodiment, the sampling port 2006 can have a plugged-port configuration. In this embodiment, the cap is a corresponding plug 2008 (e.g. a tint-plug) that a user can use to seal the sampling port 2006 by inserting the plug 2008 into the sampling port 2006. The plug 2008 can be sized such that the plug 2008 is retained within the sampling port 2006 with a friction fit or a snap-fit. The plug 2008 can include a ring 2014 attached to the top of the plug 2008. The ring 2014 allows a user to insert a finger into the ring 2014 so that the user can pull the plug 2008 out of the sampling port 2006 as shown in FIG. 23. In certain embodiments, the seal 2010 can be adhered over the top of the ring 2014 so that the seal 2010 must be broken for a user to access the ring 2014 and remove the plug 2008 from the sampling port 2006.

Turning now to FIG. 24, a sample-taking procedure is depicted. Once the cap (e.g. plug 2008) is removed from the sampling port 2006, a user can have access to the contents of the bag 1900 by way of the opened sampling port 2006. For example, a user can insert a sampling thief 2024 through the sampling port 2006 and into the bag 1900. In this manner, the user can obtain a sample of the contents of the bag 1900 through the sampling port 2006, which eliminates the need for removing the lid 2004 from the collar 102 and the bag 1900 in order to take a sample. In one example, a user can obtain a sample of the contents of the bag 1900 by using the sample thief 2024 to take a multi-level, cross-sectional sample from the contents. Once the desired samples are taken, the user can remove the sample thief 2024 from the sampling port 2006 and re-insert the cap (e.g. plug 2008) into the sampling port 2006.

Turning now to FIG. 25, a venting procedure is depicted. In addition to providing access to the bag's 1900 contents, the sampling port 2006 can also allow a user to vent the bag 1900. If the lid 2004 or the cap is removed, the bag 1900 should be vented to remove all or most of the air contained in the bag 1900 before stacking anything on the bag 1900. With the cap removed, a user can compress the top of the bag 1900 to force air 2026 out of the bag through the opened sampling port 2006. After venting the bag 1900, the user can then re-attach the cap (e.g. screw on a threaded cap or re-insert the plug 2008) into the sampling port 2006.

The aforementioned systems, components, (e.g., hermetic seal assembly system 100, hermetic seal assembly 300, collar 102, lid 104, collar 302, lid 304, lid 2004, bag 500, bag 700, bag 1900, compression member 1914, among others), and the like have been described with respect to interaction between several components and/or elements. It should be appreciated that such devices and elements can include those elements or sub-elements specified therein, some of the specified elements or sub-elements, and/or additional elements. Further yet, one or more elements and/or sub-elements may be combined into a single component to provide aggregate functionality. The elements may also interact with one or more other elements not specifically described herein.

The above examples are merely illustrative of several possible embodiments of various aspects of the present invention, wherein equivalent alterations and/or modifications will occur to others skilled in the art upon reading and understanding this specification and the annexed drawings. In particular regard to the various functions performed by the above described components (assemblies, devices, systems, circuits, and the like), the terms (including a reference to a “means”) used to describe such components are intended to correspond, unless otherwise indicated, to any component, such as hardware, software, or combinations thereof, which performs the specified function of the described component (e.g., that is functionally equivalent), even though not structurally equivalent to the disclosed structure which performs the function in the illustrated implementations of the invention. In addition although a particular feature of the invention may have been disclosed with respect to only one of several implementations, such feature may be combined with one or more other features of the other implementations as may be desired and advantageous for any given or particular application. Also, to the extent that the terms “including”, “includes”, “having”, “has”, “with”, or variants thereof are used in the detailed description and/or in the claims, such terms are intended to be inclusive in a manner similar to the term “comprising.”

This written description uses examples to disclose the invention, including the best mode, and also to enable one of ordinary skill in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that are not different from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal language of the claims.

In the specification and claims, reference will be made to a number of terms that have the following meanings. The singular forms “a”, “an” and “the” include plural referents unless the context clearly dictates otherwise. Approximating language, as used herein throughout the specification and claims, may be applied to modify a quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term such as “about” is not to be limited to the precise value specified. In some instances, the approximating language may correspond to the precision of an instrument for measuring the value. Moreover, unless specifically stated otherwise, a use of the terms “first,” “second,” etc., do not denote an order or importance, but rather the terms “first,” “second,” etc., are used to distinguish one element from another.

As used herein, the terms “may” and “may be” indicate a possibility of an occurrence within a set of circumstances; a possession of a specified property, characteristic or function; and/or qualify another verb by expressing one or more of an ability, capability, or possibility associated with the qualified verb. Accordingly, usage of “may” and “may be” indicates that a modified term is apparently appropriate, capable, or suitable for an indicated capacity, function, or usage, while taking into account that in some circumstances the modified term may sometimes not be appropriate, capable, or suitable. For example, in some circumstances an event or capacity can be expected, while in other circumstances the event or capacity cannot occur—this distinction is captured by the terms “may” and “may be.”

The best mode for carrying out the invention has been described for purposes of illustrating the best mode known to the applicant at the time and enable one of ordinary skill in the art to practice the invention, including making and using devices or systems and performing incorporated methods. The examples are illustrative only and not meant to limit the invention, as measured by the scope and merit of the claims. The invention has been described with reference to preferred and alternate embodiments. Obviously, modifications and alterations will occur to others upon the reading and understanding of the specification. It is intended to include all such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof. The patentable scope of the invention is defined by the claims, and may include other examples that occur to one of ordinary skill in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differentiate from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal language of the claims.
