The following specification particularly describes the invention and the manner in which it is to be performed.

Padding for Mechanical Interlock Kit Assembly
Field of invention
The present invention relates to mechanical interlock kit assemblies and more particularly to a corrugated padding adapted to securely hold the sides of the mechanical interlock kit assembly.
Background of the Invention
Mechanical interlock kit assemblies are well known in the art for their function of mechanical interlocking. The mechanical interlock kit assemblies are traditionally packed using a packaging material such as thermocol. In routine packaging processes, the packaging materia! is wrapped all over the sides of the mechanical interlock kit. The use of thermocol paddings for protection of the sides of mechanical interlock kit assemblies is well known in the art. However, these prior art paddings are neither recyclable, nor environment friendly. Instead, these paddings largely contribute to the environmental pollution.
Further, these conventional paddings fail to safely secure the sides of mechanical interlock kit assemblies in general and the base plates of the mechanical interlock kit assemblies in particular. The base plates of mechanical interlock kit assemblies have sharp corners that are susceptible to incur damage during the transport as the conventional paddings are incompetent to totally secure the sharp corners of the base plates.
There is a need of a padding means that overcomes all the disadvantages in the prior art.
Objects of the inventions

Object of the present invention is to provide a padding for mechanical interlock kit assembly with lesser requirement of packaging material.
Another object of the present invention is to provide a padding for mechanical interlock kit assembly that secures all four sides of the mechanical interlock kit assembly and especially the corners of the mechanical interlock kit assembly.
Yet another object of the present invention is to provide a corrugated padding that is eco-friendly, sturdy, re-usable and cheaper.
Summary of the invention
According to the present invention there is provided a packing or a padding structure adapted to securely hold a mechanical interlocking kit assembly. The padding structure comprises a first member and a second member. The first member connects in a substantially normal position to the second member. The first member is having at least a pair of identical grooves that securely hold at least one base plate of the mechanical interlocking kit assembly in addition to protecting the sides thereof.
Brief description of the invention
FIG. 1 is a top perspective view of a padding structure in accordance with the present invention adapted to hold and secure a mechanical interlock kit assembly; and
FIG. 2 is a perspective view illustrating a method of folding of the padding structure from a blank position to a three dimensional position in accordance with the present invention.
Detail description of the invention

The foregoing objects of the present invention are accomplished and the problems and shortcomings associated with the prior art. techniques and approaches are overcome by the present invention as described below in the preferred embodiments.
Referring to FIG. 1, a padding 10 adapted to securely hold a mechanical interlock kit assembly (MIL kit assembly, hereinafter) is illustrated. The padding 10 is made from a corrugated fiberboard sheet (not shown). The fiberboard sheet is a Kraft paper that is commonly known as a corrugated fiberboard sheet (CFB sheet, hereinafter). The CFB sheet includes a plurality of flutes or creases (not shown) that assists in the folding process of the CFB sheet on a box making plant, conventionally known as corrugators. The flutes also add cushioning to the padding 10. The flutes are of narrow configuration that facilitate vertical strength and crush to the padding 10. The CFB sheet is adapted to be folded or bent on the corrugators by performing a creasing operation in a predefined manner to form a three dimensional structure of the padding 10 followed by joining the end portions of the CFB sheet using a water based adhesive that is well known in the art. In this one particular embodiment, the sticking is enabled using a starched based adhesive, which is an eco-friendly material in nature.
The padding defines a cavity 24 that is configured to be stuffed with a plurality of corrugated sheets that is stick together to form a framework of a first member 12 and a second member 14. The first member 12 includes a first panel 16, a second panel 18, a third panel 20 and a fourth panel 22 that adjoin to facilitate a squarer structure to the first member 12. The second member 14 includes a fifth panel 24, a sixth panel 26, and a seventh panel 28 that adjoin to facilitate a rectangular structure to the second member 14. It is understood here that the shapes of the first member 12 and the second member 14 may vary per intended application of the padding 10.

The first pane! 16 connects to the second panel 18 along a mating edge 32. The mating edge 32 defines a first groove 34 and a second groove 36. The first groove 34 and the. second groove 36 preferably horizontally extend at a predefined distance along the first panel 16 and the second panel 18. The first groove 34 and the second groove 36 have a rectangular configuration in this one preferred embodiment. It is understood here that the configuration of the first groove 34 and the second groove 36 may vary per intended use of the padding 10. The first groove 34 and the second groove 36 are specifically adapted to accommodate a base plate (not shown) of the MIL kit assembly. The first groove 34 and the second groove 36 respectively facilitate an opening that accommodates the base plates such that all the sides of the base plate along with the sharp corners are securely held within the padding 10. In this one preferred embodiment, the first member 12 extends in a plane that is substantially normal to a plane of the second member 14. This facilitates the first groove 34 and the second groove 36 to have a right angle configuration.
Referring now to FIG. 2, a preferred method of folding adapted for the corner padding 10 is shown. In this one preferred method, the corner padding 10 is configured to have a three dimensional position from a blank position. The blank is folded along a first fold line 202, a second fold line 204, a third fold line 206, a fourth fold line 208, a fifth fold line 210, and a sixth fold line 212. The first fold line 202 facilitates folding of the first panel 16 with respect to the second panel 18. The second fold line 204 facilitates folding of the second panel 18 with respect to the third panel 20. The third fold line 206 facilitates folding of the third panel 20 with respect to the fourth panel 22. The fourth fold line 208 facilitates folding of the fourth panel 22 with respect to the fifth panel 24. The fifth fold line 210 facilitates folding of the fifth panel 24 with respect to the sixth panel 26. The sixth fold line212 facilitates folding of the sixth panel 26 with respect to the seventh panel 28. The first panel 16 is pasted to the seventh panel 28 after folding the panels 16-28 along the respective fold lines 202-212 for facilitating 'L' shape to the corner padding 10. The cavity formed within the 'L' shaped corner padding is

filled with corrugated fiberboard sheet to retain the 'L' shape of the corner padding 10.
Advantages of the present invention:
1. The padding 10 provides protection from transit damage to the base plate of MIL Kit assembly.
2. The padding 10 is helpful for packing products with base plates of similar configuration.
3. The padding 10 is having a corrugated structure that provides protection to the MIL kit assembly from all 4 sides.
4. The padding 10 is useful for packing of fragile products.
5. The kraft paper used in the padding! 0 is recyclable that makes the padding 10 eco-friendly.
6. The use of padding 10 significantly reduces the packaging content that reduces the cost of the padding 10 and makes it cheaper.
