Abstract

A micro-spill prevention trough and method for use in with intermediate bulk container (IBC) totes is disclosed herein. The micro-spill prevention trough includes an attachment portion rotationally coupled to fluid retention portion. The attachment portion is configured to be secured under a spout of an intermediate bulk container (IBC) tote. The attachment portion includes a bucket portion defining a fluid retention space. The fluid retaining portion defines a second fluid retention space, wherein the fluid retaining portion pivots between an open position and a closed position. In the closed position a front wall of the fluid retaining portion pivots into the bucket portion of the attachment portion to define a fluid retention container.

Claims (32)

1. A micro-spill prevention system comprising:

an intermediate bulk container (IBC) tote comprising a spout on a front face of the IBC tote; and

a micro-spill prevention unit secured under the spout of the intermediate bulk container (IBC) tote, the micro-spill prevention unit comprising:

a) an attachment portion secured under the spout, the attachment portion comprising a bucket portion; and

b) a fluid retaining portion rotationally coupled to the attachment portion, wherein the fluid retaining portion pivots between an open position and a closed position.

2. The micro-spill prevention system of claim 1 , the bucket portion further defining a fluid retention space.

3. The micro-spill prevention system of claim 2 , the fluid retaining portion further defining a second fluid retention space.

4. The micro-spill prevention system of claim 3 , further wherein in the closed position a front wall of the fluid retaining portion pivots into the bucket portion of the attachment portion to define a fluid retention container.

5. The micro-spill prevention system of claim 1 , wherein the fluid retaining portion comprises a flow direction path that directs fluid from the fluid retaining portion into the bucket portion in the closed position.

6. The micro-spill prevention system of claim 1 , wherein in the closed position the fluid retaining portion resides within a plane defining the front face of the IBC tote.

7. The micro-spill prevention system of claim 1 , wherein the attachment portion is coupled to the IBC tote by a securing apparatus comprising a tightening portion that frictionally and removably couples the attachment portion to the IBC tote.

8. The micro-spill prevention system of claim 1 , wherein the bucket portion comprises an interface lip, wherein the interface lip interacts with the fluid retaining portion to further define a flow direction path.

9. The micro-spill prevention system of claim 1 , wherein the bucket portion comprises a substantially flat bottom surface that extends along a first axis that is parallel to a surface on which the IBC tote rests when in use.

10. The micro-spill prevention system of claim 1 , wherein the attachment portion defines a spout engagement notch configured to interact with an underside of an outlet port comprising the spout of the IBC tote, such that portions of a wall comprised on the bucket portion extend beyond a drip location of the outlet port.

11. The micro-spill prevention system of claim 10 , wherein the wall increases in height as the wall extends away from the bucket portion.

12. The micro-spill prevention system of claim 10 , wherein the fluid retaining portion comprises a capture area defined by a base wall, first and second sidewalls, a front wall, and a rear wall.

13. A micro-spill prevention system comprising:

an intermediate bulk container (IBC) tote comprising a spout on a front face of the IBC tote; and

a micro-spill prevention unit secured under the spout of the IBC tote, the micro-spill prevention unit comprising:

a) an attachment portion secured under the spout, the attachment portion comprising a bucket portion; and

b) a fluid retaining portion rotationally coupled to the attachment portion, wherein the fluid retaining portion pivots between an open position and a closed position, wherein the fluid retaining portion comprises a capture area defined by a base wall, first and second sidewalls, a front wall, and a rear wall, the fluid retaining portion further defines a flow direction path, wherein the flow direction path is defined by portions of the front wall, the base wall, and the first and second sidewalls.

14. The micro-spill prevention system of claim 13 , the bucket portion defining a fluid retention space and the fluid retaining portion further defining a second fluid retention space.

15. The micro-spill prevention system of claim 13 , further wherein in the closed position a front wall of the fluid retaining portion pivots into the bucket portion of the attachment portion to define a fluid retention container.

16. The micro-spill prevention system of claim 13 , wherein the first and second sidewalls are coupled to wing supports, wherein the wing supports support first and second wings.

17. The micro-spill prevention system of claim 13 , wherein the front wall and at least a portion of sidewalls of the capture area of the fluid retaining portion are located over the attachment portion in the open position, wherein, responsive to a fluid overflowing the front wall, the liquid is retained within the bucket portion.

18. The micro-spill prevention system of claim 13 , wherein in the closed position portions of first and second edges of a wall of the attachment portion are adjacent to the first and second sidewalls of the capture area of the fluid retaining portion.

19. A micro-spill prevention system comprising:

an intermediate bulk container (IBC) tote comprising a spout on a front face of the IBC tote; and

a micro-spill prevention unit secured under the spout of the IBC tote, the micro-spill prevention unit comprising:

a) an attachment portion secured under the spout by a securing apparatus comprising a tightening portion that frictionally and removably couples the attachment portion to the IBC tote, the attachment portion comprising a bucket portion; and

b) a fluid retaining portion rotationally coupled to the attachment portion, wherein the fluid retaining portion pivots between an open position and a closed position, the fluid retaining portion comprising first and second sidewalls coupled to wing supports, wherein the wing supports support first and second wings.

20. The micro-spill prevention system of claim 19 , further wherein in the closed position a front wall of the fluid retaining portion pivots into the bucket portion of the attachment portion to define a fluid retention container.
