Description

Double box packaging made of a composite stump blank is a method of manufacturing

Technical field

The present invention relates generally to containers, and in particular, relates to containers having an inner box that is structurally configured to protect an object stored therein and an outer box that surrounds the inner box.

BACKGROUND OF THE INVENTION

To date, much effort has been focused on developing double-wall or double box packaging. U.S. Pat. No. 975,121, issued to Carter, discloses a double-wall box made of a single piece of flat material having cooperating portions adapted to be folded and joined to form two complete, interconnected boxes, one box is located inside the second box and is protected by the second box.

US Patent No. 3,029,008, issued to Membrino, discloses a composite package for the carriage of articles having a flexible inner liner that is adhered to the outer package. The inner liner is typically a continuous tube which is cut and inserted into the outer shell, the tube being sealed and using heat at the bottom thereof. The inner liner is typically made of a resilient plastic material, such as polyethylene, while the outer shell is typically made of a rigid pulp board, paper board or corrugated, cardboard, flat material.

U.S. Patent No. 3,997,593, issued to Rotman, discloses a carton box that has the ability to withstand collapse when stored and other cartons, or when handled with care. The carton is made of a solid stump blank which comprises individual parts and has a double front wall and a double bottom wall. The double front wall is structurally designed to withstand compression under load, and the double bottom wall creates a rigid bottom that resists deformation under load, as well as

This ensures that the articles stored in the package will not fall out through the openings that often occur in conventionally folded cardboard boxes.

U.S. Patent No. 4,388,999, issued to Berry et al., Discloses a cardboard box made of a single stump blank comprising a series of panels which are hingedly attached to each other and which spiral to form a double-walled tube, the cardboard the box has spacers at all four corners to maintain space between the corresponding inner wall and the outer wall.

There are many problems associated with the state of the art described above. First of all, the prior art teaches the use of a single stump blank for making both the inner wall and the outer wall of the double-walled package. However, the use of a single stump blank may result in a package having an outer shell whose outer aesthetic appearance is less pleasant. The prior art also requires a relatively complex machine for the production of complex, solid, pre-cut blanks which are intended to be folded into a double box package. Therefore, there is a need for such a double box wrapper whose outer layer can be made of aesthetically pleasing material using less complex stump blanks. There is also a need to develop such containers which can vary in response to the type of article to be placed in the container. In addition, there is a need to minimize the amount of materials used and the costs associated with preparing such materials.

Despite the advantages of the prior art, there remains a need for such a double-walled package made of a composite blank that may be folded to form a complete inner box surrounded by the complete outer box.

SUMMARY OF THE INVENTION

The present invention is directed to making a container having an inner box that surrounds and protects the outer boxes. Such a package is preferably used for packaging articles such as fragrant cosmetic perfumes or glass containers that may be damaged during packaging or transport. The present invention also minimizes the amount of work to be done

It requires in the prior art the production of double-wall packs in which the inner box is typically made separately from the outer box. Such prior art processes are extremely labor intensive and cost-effective.

In certain preferred embodiments of the present invention, the package comprises a first stump blank having fold lines and rows of generally rectangular panels hingably attached to each other on the fold lines of the first stump blank and a second blank blank having fold lines and rows of generally rectangular panels that are hinged. they connect together on the fold lines of the second stump blank.
