In general, the present invention relates to a hermetic seal assembly for a bag or flexible container.
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.
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. A collar having a top end and a bottom end opposite thereto, an internal wall that defines a through passage that extends between the top end and the bottom end. The collar can include a lip on the top end and a web on the bottom end, wherein the lip is on the perimeter of the top end and the web extends outwards from the bottom end and substantially parallel. The web of the collar is integrated to the inner layer and the outer layer at the opening. A lid can be provided that is configured to releasably attach to the lip of the collar to provide a hermetic seal at the opening.
In accordance with an embodiment of the present invention, a bulk bag is provided. The bag has a cube-like shape that is configured to hold a volume of a material, the bag having a front side, a back side opposite to the front side, a left side, a right side opposite the left side, a top side, and a bottom side opposite the top side. The bag includes an opening on the top side of the bag, wherein the opening is formed by at least one of the inner layer or the outer layer. The bag includes an inner layer that is configured to provide an airtight enclosure for the material, wherein the airtight enclosure can be accessed via the opening. The bag includes an outer layer that is positioned around the inner layer, wherein the outer layer provides structural support and integrity with a ribbon weave. The opening includes a neck formed by at least one of the inner layer or the outer layer. The bag includes a collar having a top end and a bottom end opposite thereto, an internal wall that defines a through passage that extends between the top end and the bottom end, an external wall opposite the internal wall, and the collar having a thickness and a diameter for the through passage. The collar can be positioned over the neck and with at least one of the inner layer or the outer layer folded over a lip of the collar, wherein at least one of the inner layer or the outer layer are folded onto the external wall of the collar. The bag further includes a lid that is releaseably coupled to the collar, wherein the lid when attached to the collar applies a force to press the lid, the outer layer, the inner layer, and the lip of the collar together.
In accordance with an embodiment of the present invention, a hermetic seal assembly system is provided that includes at least the following: a bag that stores a material, the bag having a first end and a second end opposite thereto, and an opening at the first end; 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; a collar having a top end and a bottom end opposite thereto, an internal wall that defines a through passage that extends between the top end and the bottom end; the collar further includes an external wall; the collar having: a lip on the top end; a web that is perpendicular and outwardly extending from the external wall; and a support rib in between the lip and the web; the collar is affixed around a portion of the bag such that the outer layer is in contact with the internal wall and the external wall; a compression member that is configured to be positioned around the collar to compress the outer layer and the inner layer toward the external wall of the collar; and a lid that is configured to releaseably attach to the lip of the collar to provide a hermetic seal at the opening, wherein the lip is in contact with the outer layer, the lid is in contact with the inner layer, and the lid can couple to the lip with the outer layer and the inner layer in between.
