Abstract

A method and system for stacking containers each container of a type having a front face having a truncated trapezoidal shape, a rear face having a truncated trapezoidal shape, a top base, a bottom base, a first vertical side adjacent to the top base, a second vertical side adjacent to the top base, a first sloped side between the first vertical side and the bottom base, a second sloped side between the second vertical side and the bottom base. A discharge valve projects from the bottom base where the first vertical side defines a platform for supporting an RFID tag. The containers are configured to be stackable in a manner to provide simultaneous reading of the multiple RFID tags on the platforms.

Claims (50)

1. A method for stacking a plurality of containers, comprising:

a) providing a plurality of containers, each container, comprising:

a front face having a truncated trapezoidal shape;

a rear face having a truncated trapezoidal shape;

a top base;

a bottom base;

a first vertical side adjacent to said top base;

a second vertical side adjacent to said top base;

a first sloped side between said first vertical side and said bottom base;

a second sloped side between said second vertical side and said bottom base;

wherein said front face, rear face, top base, bottom base, first vertical side, and second vertical side are configured to define an enclosure;

a discharge valve projecting from said bottom base; and,

wherein said first vertical side defines a platform for supporting an RFID tag;

b) arranging a first layer of containers, comprising:

a first container;

a second container positioned adjacent to said first container so that their respective top bases abut;

a third container positioned adjacent to said second container so that its second sloped side abuts a second sloped side of the second container;

a fourth container positioned adjacent to said third container so that its first sloped side abuts a first sloped side of the third container;

a fifth container positioned adjacent to said fourth container so that their respective top bases abut;

a sixth container positioned adjacent to said fifth container so that its second sloped side abuts a second sloped side of the fifth container and a first sloped side of the sixth container abuts a second sloped side of said first container;

wherein said first container, said second container, said third container, said fourth container, said fifth container and said sixth container are positioned about a central axis;

c) stacking additional layers of containers along said central axis, said additional layers being configured the same as said first layer of containers, wherein said first vertical side defining a platform for supporting an RFID tag is external for providing simultaneous reading of multiple RFID tags on the platforms.

2. The method of claim 1 wherein each container of said plurality of containers includes a raised panel on either said front face or said rear face, and a recessed panel on an opposite face for providing nesting when the containers are stacked.

3. The method of claim 1 wherein each container of said plurality of containers is configured to contain dry agricultural product.

4. The method of claim 1 wherein said first layer and additional layers of stacked layers are positioned between a top pallet plate and a bottom pallet plate, and wherein said bottom pallet plate is positioned on a pallet element.

5. The method of claim 1 wherein said first layer and additional layers of stacked layers are positioned between a top pallet plate and a bottom pallet plate, and wherein said bottom pallet plate is positioned on a pallet element; and,

wherein the bottom pallet plate is secured to the top pallet plate by an elastic cord.

6. A system for stacking a plurality of containers, comprising:

a) a plurality of containers, each container, comprising:

a front face having a truncated trapezoidal shape;

a rear face having a truncated trapezoidal shape;

a top base;

a bottom base;

a first vertical side adjacent to said top base;

a second vertical side adjacent to said top base;

a first sloped side between said first vertical side and said bottom base;

a second sloped side between said second vertical side and said bottom base;

wherein said front face, rear face, top base, bottom base, first vertical side, and second vertical side are configured to define an enclosure;

a discharge valve projecting from said bottom base; and,

wherein said first vertical side defines a platform for supporting an RFID tag;

b) wherein said plurality of containers defines a first layer of said plurality of containers,

said first layer comprising:

a first container;

a second container positioned adjacent to said first container so that their respective top bases abut;

a third container positioned adjacent to said second container so that its second sloped side abuts a second sloped side of the second container;

a fourth container positioned adjacent to said third container so that its first sloped side abuts a first sloped side of the third container;

a fifth container positioned adjacent to said fourth container so that their respective top bases abut;

a sixth container positioned adjacent to said fifth container so that its second sloped side abuts a second sloped side of the fifth container and a first sloped side of the sixth container abuts a second sloped side of said first container;

wherein said first container, said second container, said third container, said fourth container, said fifth container and said sixth container are positioned about a central axis;

c) additional layers of containers being stacked along said central axis, said additional layers being configured the same as said first layers of containers, wherein said first vertical side defining a platform for supporting an RFID tag is external for providing simultaneous reading of multiple RFID tags on the platforms.
