Abstract

In accordance with presently disclosed embodiments, a collapsible and optionally stackable storage container for bulk material is provided. The disclosed storage container includes a collapsible frame defined by a rigid upper support structure, a rigid lower support structure and a support member coupled at one end to the upper support structure and coupled at another end to the lower support structure. An actuator is also provided which is coupled to the support member at one end. The disclosed storage container further includes a storage sack having an upper portion coupled to the upper support structure and a lower portion coupled to the lower support structure. The lower portion of the storage sack is generally taper-shaped and may be equipped with a discharge opening that enables release of the bulk material onto a conveyor, which may be employed when the collapsible storage container is integrated into a bulk storage system.

First claim

What is claimed is:

1. A bulk storage container, comprising:
a collapsible frame defined by a rigid upper support structure, a rigid lower support structure, a first support member, and a second support member;
a pair of tracks formed along opposite sides of the lower support structure, wherein a first end of the first support member is coupled to a first end of the upper support structure and a second end of the first support member is coupled to a first track of the pair of tracks, wherein a first end of the second support member is coupled to a second end of the upper support structure and a second end of the second support member is coupled to a second track of the pair of tracks, wherein the first support member and the second support member transition between an expanded position and a collapsed position by sliding the second end of the first support member and the second end of the second support member horizontally along the pair of tracks, and wherein the first support member and the second support member extend to a fully vertical position in the expanded position;
an actuator coupled to the first support member at one end;
a storage sack having an upper portion coupled to the upper support structure and a lower portion coupled to the lower support structure, the lower portion being a conical taper-shaped, wherein the upper portion of the storage sack is formed of a plurality of connected panels, wherein the plurality of panels are at least one of one or more rigid panels and one or more semi-rigid panels.

2. The bulk storage container according to claim 1 , wherein the upper support structure is rectangular shaped and the lower support structure is rectangular shaped.

3. The bulk storage container according to claim 1 , wherein the first support member is coupled to one side of the upper and lower support frames and the second support member is coupled to an opposite side of the upper and lower support frames.

4. The bulk storage container according to claim 3 , further comprising another actuator coupled to the second support member.

5. The bulk storage container according to claim 3 , further comprising a cross bar coupling the first support members to the second support member.

6. The bulk storage container according to claim 1 , wherein the storage sack comprises a material selected from the group consisting of a cloth, a canvas, a canvas coated with a rubber material, a canvas coated with an elastomeric material, a woven nylon, woven polyethylene, a plastic, a woven glass coated with a rubber material, a woven glass coated with an elastomeric material, a gunny sack and combinations thereof.

7. The bulk storage container according to claim 1 , wherein the lower portion of the storage sack is formed of a flexible material.

8. The bulk storage container according to claim 1 , wherein the storage sack has an interior formed of a plurality of connected tension panels.

9. The bulk storage container according to claim 1 , further comprising a pair of tubes formed along opposite sides of the lower support frame, a cross-section of the tubes being shaped to accommodate the forks of a forklift.

10. The bulk storage container according to claim 1 , further comprising a discharge opening formed in the lower portion of the storage sack, the discharge opening being equipped with a material control device selected from the group consisting of a valve, swing gate, pinch gate, annular pinch valve, butterfly valve, and combinations thereof.

11. The bulk storage container according to claim 1 , wherein the collapsible frame is adapted to partially collapse upon the storage sack to enable transportation of the bulk material on a bed of a transportation unit.

12. The bulk storage container according to claim 1 , wherein the lower portion of the storage sack is coupled to the lower support structure by one of a rope or panel.

13. The bulk storage container according to claim 1 , further comprising a sonic or ultrasonic vibrator coupled to the lower portion of the storage sack.

14. The bulk storage container according to claim 1 , further comprising another collapsible frame wherein the collapsible frames are stackable.

15. A bulk storage system, comprising:
a transportation unit; and
one or more bulk storage containers disposed on the transportation unit, the one or more bulk storage containers comprising:
a collapsible frame defined by a rigid upper support structure, a rigid lower support structure and a first support member and a second support member;
a pair of tracks formed along opposite sides of the lower support structure, wherein a first end of the first support member is coupled to a first end of the upper support structure and a second end of the first support member is coupled to a first track of the pair of tracks, wherein a first end of the second support member is coupled to a second end of the upper support structure and a second end of the second support member is coupled to a second track of the pair of tracks, wherein the first support member and the second support member transition between an expanded position and a collapsed position by sliding the second end of the first support member and the second end of the second support member horizontally along the pair of tracks, and wherein the first support member and the second support member extend to a fully vertical position in the expanded position;
an actuator coupled to the first support member at one end; and
a storage sack having an upper portion coupled to the upper support structure and a lower portion coupled to the lower support structure, the lower portion being a conical taper-shaped, wherein the upper portion of the storage sack is formed of a plurality of connected panels, wherein the plurality of panels are at least one of one or more rigid panels and one or more semi-rigid panels.

16. The bulk storage system according to claim 15 , further comprising a conveyor disposed beneath one or more bulk storage containers.

17. The bulk storage system according to claim 16 , wherein the one or more bulk storage containers comprising a discharge opening formed in the lower portion of the storage sack, the discharge opening being equipped with a material control device selected from the group consisting of a valve, swing gate, pinch gate, annular pinch valve, butterfly valve and combinations thereof.

18. The bulk storage system according to claim 15 , wherein the first support member is coupled to one side of the upper and lower support frames and the second support member is coupled to an opposite side of the upper and lower support frames, and comprises another actuator coupled to the second support member.

19. The bulk storage system according to claim 15 , further comprising a sonic or ultrasonic vibrator coupled to the lower portion of the storage sack of the one or more bulk storage containers.
