Abstract
Abstract A plurality of rectangular plates having stacking elements on their upper and lower surfaces, the stacking elements being complimentary to those on rectangular containers such that the plates can be connected between any two containers in a stack. The plates further have complimentary interconnecting elements on their lateral sides to allow locking together of adjacent stacks of containers into a complact block.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
162 words
A connecting device for the combined vertical and side-by-side stacking of rectangular containers which have complementary interlocking stacking elements only on their upper and lower surfaces, the device comprising a plurality of rectangular connector plates of minimal thickness and arranged in edge to edge relation with each other, the connector plates having upper and lower surfaces to confront the bottoms and tops of such containers, and also having lateral sides to confront adjacent lateral sides of adjacent connector plates, the connector plates having complementary interlocking type stacking elements on their upper and lower surfaces to interlock with similar stacking elements of the containers, such that they can be connected between any two containers in a stack, such plates further having complementary interlocking elements on their lateral sides and rigidly securing the lateral sides of adjacent plates together, such that aligned plates in adjacent container stacks can be detachably interconnected, to thereby lock together a plurality of container stacks in a compact block.
Claim 2
Dependent Claim
162 words
A connecting device for the combined vertical and side-by-side stacking of rectangular containers which have complementary interlocking stacking elements only on their upper and lower surfaces, the device comprising a plurality of rectangular connector plates of minimal thickness and arranged in edge to edge relation with each other, the connector plates having upper and lower surfaces to confront the bottoms and tops of such containers, and also having lateral sides to confront adjacent lateral sides of adjacent connector plates, the connector plates having complementary interlocking type stacking elements on their upper and lower surfaces to interlock with similar stacking elements of the containers, such that they can be connected between any two containers in a stack, such plates further having complementary interlocking elements on their lateral sides and rigidly securing the lateral sides of adjacent plates together, such that aligned plates in adjacent container stacks can be detachably interconnected, to thereby lock together a plurality of container stacks in a compact block.
Claim 3
Dependent Claim
18 words
The device of claim 1 wherein the plates have a height substantially smaller than that of each container.
Claim 4
Dependent Claim
16 words
The device of claim 1 wherein the plates are at least partially hollow at their bottoms.
Claim 5
Dependent Claim
38 words
The device of claim 1 wherein at least one of the plates has stacking elements only on its upper side and at its lateral sides, and has at its lower side a contiguous face with increased friction coefficient.
Claim 6
Dependent Claim
34 words
The device of claim 1 wherein at least one of the plates has stacking elements only on its lower and lateral sides and is provided at its upper side with a smooth contiguous surface.
