Description

Hermetic seal for foil-lined FIBC (bulk bag) {HERMETIC SEAL FOR FOIL-LINED FIBC (BULK BAG)}

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

The use of large textile bags, generally referred to as flexible intermediate bulk containers (FIBC) or simply bulk bags, has become common for transporting bulk quantities of material (eg, powdered material, granular material, liquid, etc.). Bulk bags can be lifted, moved, or transported by forklifts and other material handling equipment with hooks or tines. Fabrics for bulk bags are generally woven from strong, tape-like artificial plastic fibers (eg, polypropylene, etc.), but natural fibers may also be used. Flexible intermediate bulk containers are widely used to contain, store, transport, and release all types of flowable materials.

The bulk bag can also be made to include an inner layer to prevent air penetration or to prevent exposure to ambient humidity conditions. Often, a foil laminate can be included as an inner layer to limit moisture absorption. For example, a bulk bag may contain a flux material that is susceptible to moisture absorption and allows hydrogen to diffuse within the weld metal. Although bulk bags with an inner layer of the foil laminate can limit exposure to moisture, the effectiveness of the foil laminate upon opening of the bulk bag is reduced.

Accordingly, there is a need for an improved bulk bag assembly, system, or methodology that addresses these problems.

In accordance with an embodiment of the present invention, a sealing assembly system for a bulk bag is provided. The sealing assembly may include a bag for storing material, the bag including an opening.

The collar may include a lip on the top end and a web on the bottom end, the lip being positioned on the circumference of the top end, and the web extending outwardly from the bottom end and substantially parallel. The web of collar is integrated into the inner and outer layers at the openings. A lid may be provided, such a lid being releasably attached to the lip of the collar and configured to provide an airtight 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 furthermore, when removed from the sampling port, while such a lid remains attached to the lip of the collar Can provide access to

Referring now to FIG. 22, a lid 2004 is shown. Lid 2004 may include some or all of the same components and features as described above with respect to lid 104 or 304. For example, the cover 2004 may be releasably coupled to the collar 102, and the cover 2004 is a top side (2018), a bottom side (not shown), between the top side (2018) and the bottom side. And a protrusion 2022 on the circumference of the lid 2004 and the sidewall of the lid. In an embodiment, the lid 2004 may include a locking mechanism that can be removed from the collar 102 on the first opening of the lid 2004.

In addition, the lid 2004 may 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 the use of the sampling port 2006, the user does not need to remove the lid 2004 from the collar/bag connection for sample acquisition. Thus, the seal created between the cover 2004, the collar 102, and the bag 1900 is maintained without damage or interference, caused by friction in the bag 1900 during removal and relocation of the cover 2004. To prevent wear and tear. Sampling port 2006 allows for regular monitoring of the contents of bag 1900 over time, without risk of damaging bag 1900 at the location of the junction where cover 2004 connects to collar 102. have. Further, the sampling port 2006 allows a user to vent the bag 1900 without having to remove the lid 2004 from the collar 102 and bag 1900.

Sampling port 2006 may be molded into the top side of lid 2004. The cap corresponds to the opening of the sampling port 2006 and, when coupled with the opening, can seal the sampling port 2006. The cap 2008 may be, for example, a threaded cap, a plug 2008, a latched cover, or the like, depending on the type of sampling port 2006 used. In certain embodiments, the cap, when coupled with the opening of the sampling port 2006, is depressed under the top side 2018 of the lid 2004. In certain embodiments, the seal 2010 is placed over the cap such that a portion of the seal 2010 is attached to the cap and another portion of the seal 2010 is attached to the top side 2018 of the lid 2004. Or can be attached. In this way, when the user removes the cap from the sampling port 2006, the seal 2010 will rupture. The ruptured seal 2010 may provide an indication that the cap has been removed. The sealing portion 2010 may be installed by the original manufacturer or distributor, and using any available means for tamper-proof processing or selection of the sealing portion 2010, the sealing portion 2010 of the cap is removed. You will understand that the possibility of destruction can be improved. The top side 2018 of the lid 2004 may also include a label 2012, such a label for sampling the contents of the bag 1900 through the sampling port 2006, and the bag 1900 through the sampling port 2006. ), and/or information about the contents of the bag 1900 including identification information or material safety information.

By way of example and not limitation, sampling port 2006 may be circular and/or may be 70 mm in diameter. However, it will be appreciated that the sampling port 2006 may have any shape or size selected using appropriate engineering judgment. In certain embodiments, the sampling port 2006 may have a diameter 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 a support-threaded port, for example. In this embodiment, the cap is a corresponding threaded cap, and the user opens the sampling port 2006 using such a corresponding threaded cap by screwing the cap onto the thread of the sampling port 2006. Can be sealed. To remove the threaded cap for access to the sampling port 2006, the user can screw the threaded cap off the sampling port 2006. In another embodiment, sampling port 2006 may have a pluggable-port configuration. In this embodiment, the cap is a corresponding plug 2008 (e.g., a tint-plug), and the user seals the sampling port 2006 by inserting the plug 2008 into the sampling port 2006. can do. The size of the plug 2008 may be determined such that the plug 2008 remains within the sampling port 2006 with a friction fit or snap-fit. The plug 2008 may include a ring 2014 attached to the upper end 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 is the upper end of the ring 2014 so that the user can access the ring 2014 and remove the plug 2008 from the sampling port 2006 only by breaking the seal 2010. Can be attached to the top.

Referring now to FIG. 24, a sample-acquisition process is illustrated. When the cap (eg, plug 2008) is removed from the sampling port 2006, the user can access the contents of the bag 1900 through the open sampling port 2006. For example, a user may insert sampling collector 2024 through sampling port 2006 and into bag 1900. In this way, the user can obtain a sample of the contents of the bag 1900 through the sampling port 2006, which removes the cover 2004 from the collar 102 and bag 1900 to take a sample. Eliminate the need to do. In one example, a user may obtain a sample of the contents of the bag 1900 by using the sampling collector 2024 to take a multi-level, cross-sectional sample from the contents. Once the desired sample has been taken, the user can remove the sampling collector 2024 from the sampling port 2006 and reinsert the cap (eg, plug 2008) into the sampling port 2006.

Referring now to Fig. 25, the evacuation process is shown. In addition to providing access to the contents of bag 1900, sampling port 2006 may also allow a user to vent bag 1900. If the lid 2004 or cap has been removed, the bag 1900 must be evacuated to remove all or most of the air contained within the bag 1900 prior to stacking anything on the bag 1900. With the cap removed, the user can compress the upper end of the bag 1900 to force the air 2026 to the outside of the bag through the opened sampling port 2006. After evacuating the bag 1900, the user may then reattach the cap into the sampling port 2006 (eg, screwing the threaded cap or reinserting the plug 2008).
