Abstract

A new storage apparatus is provided which includes a rectangular box-like containment vessel in which a false movable floor is provided over the bottom floor. A dunnage bag or other actuator is provided to selectively raise and lower the false floor to facilitate self-evaluation and discharge of dry flowable material through a discharge port. The false floor structure may be removed to provide for versatility and different storage options. For example, the containment vessel can be left empty to provide for storage of other objects through openable doors or a pillow tank may be installed within the containment vessel to provide for liquid holding capabilities.

Claims

1. An apparatus for storing and discharging material, comprising:

a containment vessel having a top, a bottom spaced from the top, and an outer sidewall extending generally around a periphery of the top and bottom and vertically between the top and the bottom;

a liner in the containment vessel, the liner having an internal chamber for surrounding material therein;

a discharge port through a lower portion of the liner for dispensing material;

a movable floor arranged along the bottom, the movable floor carrying at least a portion of the liner, the movable floor including a distal end spaced laterally from the discharge port and a proximate end arranged between the distal end and the discharge port; and

an inflatable bag arranged proximate the bottom and under the floor proximate the distal end, the inflatable bag having an inflated state raising the distal end above the proximate for gravitationally conveying material through the discharge port.

2. The apparatus of claim 1, further comprising a support back integrally connected to the movable floor, the support back including a rear wall projecting vertically from the distal end and a pair of opposed walls spaced on opposed sides of the rear wall, the opposed walls extending forwardly from the rear wall.

3. The apparatus of claim 2, wherein the support back extends a vertical distance that is less than the spacing between the top and bottom such that when the distal end is raised during the inflated state a clearance exists between the support back and the top.

4. The apparatus of claim 1, wherein the sidewall includes at least one door having open and closed positions, further comprising a liner support mounted to the container vessel and behind the at least one door for supporting the liner when the door is in the open position, wherein the discharge port includes an open state and a closed state, the discharge port being arranged in communication with the door for discharging material through the door when in the open position with the discharge port in the open state.

5. The apparatus of claim 4, wherein the liner comprises a flexible material flap at the discharge port, wherein the flexible material flap is secured shut to close the discharge port and released to open the discharge port.

6. The apparatus of claim 5, wherein the flexible material flap forms a discharge chute when released.

7. The apparatus of claim 6, wherein the liner support comprises a perforated wall, further comprising a gate in the perforated wall receiving the discharge chute therethrough when the discharge chute is released.

8. The apparatus of claim 4, wherein said liner supports includes a plurality of spaced apart bars extending across a portion of the containment vessel.

9. The apparatus of claim 1, wherein the bottom includes a bottom floor extending horizontally, and wherein the movable floor is hinged to the to the bottom floor rearward and proximate the discharge port, the movable floor pivoting relative to the bottom via the hinge.

10. The apparatus of claim 6, wherein the inflatable bag is sandwiched between the movable floor and the bottom floor.

11. The apparatus of claim 10, further comprising means for securing the inflatable bag to the bottom floor.

12. The apparatus of claim 1, wherein the containment vessel is a rectangular box like structure comprising a top panel and a bottom panel arranged horizontally parallel, and a pair of front and back walls in spaced relation extending transversely between the top and bottom panels, spaced relation, and a pair of end walls in spaced relation extending transversely between the top and bottom panels and transversely between the front and back walls, further comprising an fill port formed through the top panel, and a closure element having an open state for allowing flow of material through the fill port and a closed state for preventing flow through the fill port.

13. The apparatus of claim 1, further comprising means for tracking contents contained in the containment vessel, said tracking means being contained at least partially in the containment vessel.

14. The apparatus of claim 13, further comprising tamper resistant means for indicating when the contents of the containment vessel when filled and enclosed has been tampered with.

15. The apparatus of claim 1, further comprising a pillow tank, the containment vessel having a first state wherein the pillow tank is contained in the containment vessel for holding liquid and a second state wherein the pillow tank is not contained therein for holding granular material.

16. The apparatus of claim 15, further comprising a third state in which the pillow tank and the movable floor are removed from the containment vessel.

17. The apparatus of claim 1, further comprising baffle means connected to the liner for directing material toward the discharge port.

18. The apparatus of claim 1, further comprising an aeration blower mounted through the containment vessel, the aeration blower being in operable communication with the internal chamber of the liner.

19. An apparatus for storing and discharging material, comprising:

a containment vessel having a top, a bottom floor spaced below the top, and an outer side wall extending generally around a periphery of the top and the bottom floor and vertically between the top and the bottom floor;

a discharge area proximate a lower portion of the containment vessel;

a movable floor on top of the bottom floor, the movable floor having a top support surface; and

an actuator acting upon the movable floor, the actuator operable to raise the movable floor and thereby incline the top support surface with a slope that angles downwardly generally toward the discharge area.

20. The apparatus of claim 19, further comprising:

a liner in the containment vessel, the liner having an internal chamber for surrounding material therein; and

a discharge port through a lower portion of the liner for dispensing material, the discharge port being located at the discharge area.

21. The apparatus of claim 19, further comprising a support back integrally connected to the movable floor, the support back including a rear wall projecting vertically from the distal end and a pair of opposed walls spaced on opposed sides of the rear wall, the opposed walls extending forwardly from the rear wall, wherein the support back extends a vertical distance that is less than the spacing between the top and bottom such that when the distal end is raised during the inflated state a clearance exists between the support back and the top.

22. The apparatus of claim 19, wherein the outer sidewall includes at least one door having open and closed positions, further comprising a liner support mounted to the container vessel and behind the at least one door for supporting the liner when the door is in the open position, wherein the discharge port includes an open state and a closed state, the discharge port being arranged in communication with the door for discharging material through the door when in the open position with the discharge port in the open state.

23. The apparatus of claim 22, wherein the liner comprises a flexible material flap at the discharge port, wherein the flexible material flap is secured shut to close the discharge port and released to open the discharge port.

24. The apparatus of claim 23, wherein the flexible material flap forms a discharge chute when released.
