Multi-chamber container for bulk materials, and method of filling a multi-chamber container

A multi-chamber bulk material container comprising:

• a primary container comprising sidewalls, a bottom wall, and a bulkhead configured to define first and second chambers on opposite sides of said bulkhead, wherein said first chamber is adapted to contain a first bulk material and said second chamber is adapted to contain a second bulk material that is different in composition from the first bulk material;
• a first openable aperture defined in said bottom wall of said primary container at said first chamber, said first openable aperture configured to selectively dispense the first bulk material;
• a second openable aperture defined in said bottom wall of said primary container at said second chamber, said second openable aperture configured to selectively dispense the second bulk material;
• and
• a secondary container positioned in said second chamber of said primary container, said secondary container comprising a generally sealable and moisture-resistant liner that is openable at a bottom end near said second openable aperture of said bottom wall of said primary container at said second chamber.

A multi-chamber bulk material container comprising:

• a primary container comprising at least one sidewall and a bottom wall defining a first chamber for containing a first bulk material, wherein said bottom wall is openable to dispense the first bulk material from the first chamber;
• a secondary container positioned in said first chamber of said primary container and defining a second chamber at least partially within said first chamber of said primary container, said secondary container comprising a generally sealable and moisture-resistant liner having closeable upper and lower end portions, said lower end portion being foldable and held closed by the first bulk material in said first chamber;
• and
• wherein said secondary container is configured to isolate the second bulk material in said second bulk chamber from at least one of (i) the first bulk material in said first chamber, and (ii) a contaminant from outside of said primary container and said secondary container.

A method of filling a multi-chamber bulk material container, said method comprising:

• positioning a multi-chamber bulk material container at a filling apparatus, the multi-chamber bulk material container including a primary container defining a primary chamber and a secondary container positioned in the primary chamber;
• dispensing a first amount of a first bulk material into the primary chamber of the multi-chamber bulk material container until at least a closed lower end portion of the secondary container is surrounded by the first bulk material;
• dispensing a second bulk material into the secondary container, whereby at least a portion of the second bulk material is positioned above the first amount of the first bulk material that is in the primary chamber;
• dispensing a second amount of the first bulk material into the primary chamber of the multi-chamber bulk material container until at least a portion of the second bulk material is surrounded by the second amount of the first bulk material in the primary chamber;
• and
• closing an upper end portion of the secondary container.
