This disclosure relates to box structures and has particular applicability to box structures which are erected to form an inner display box and an outer covering box.
It is known to have an outer box that receives a display box for protecting the contents of the display box, such as during shipment. The display box typically has one or more openings in a front wall through which the contents of the display box are visible.
Although display boxes having outer cover boxes are known, a need nevertheless exists for improvements in such box structures. Known display box designs suffer from one or more of a number of disadvantages. For example, the display box openings can weaken the front panel, resulting in possible kinking or buckling of the front panel and in a box having lesser crush strength when stacked. In addition, it can be time consuming to disassemble the outer box to provide the inner display box with its contents ready for display. Furthermore, stresses applied to the inner box during the manufacture and erection process of a combined inner/outer box structure can cause buckling or kinking of the walls of the inner box.
Therefore, a need exists for an improved display box structure that addresses one or more of these or other disadvantages.
A box forming structure is erected to form an inner display box and an outer box. When erected, the inner display box is positioned at least partially within, and desirably substantially entirely within, the outer box.
The box forming structure in one form comprises an inner box forming structure and an outer box forming structure. In accordance with and aspect of this disclosure, the inner and outer box forming structures are interconnected and can be provided in a knocked down substantially flat format that is erected to form the inner display box and outer box. The knocked down box forming structure can be erected, such as at a product packaging plant, to form the inner display box, which can be filled with product, and the outer box.
In accordance with one aspect of an embodiment, a box forming structure upon erection, comprises an inner display box and an outer box, the inner display box being positioned at least partially within the outer box upon erection of the box forming structure. The box forming structure in accordance with this aspect can comprise an inner box forming panel structure comprising a plurality of at least three inner box wall panels including an inner box front wall panel, the inner box wall panels forming an inner display box having inner box corners at the intersection of respective pairs of inner box wall panels when the box forming structure is erected. In addition, a plurality of the inner box wall panels can comprise bottom panel extension flap portions that comprised the bottom of the inner display box when the box forming structure is erected. Also, the box forming structure in accordance with this aspect can comprise an outer box forming panel structure comprising a plurality at least three outer box wall panels including an outer box front wall panel. The outer box forming wall panels desirably form an outer box structure having the same number of outer box corners as the number of inner box corners when the box forming structure is erected. A plurality of the outer box wall panels can comprise top panel extension flap portions that comprise the top of the outer box when the box forming structure is erected. The inner box front wall portion can also comprise at least one tear off display panel portion that is desirably adhered to the adjacent surface of the outer box front wall portion. In addition, in this aspect the outer box wall panels that form one of the outer box corners are desirably separated from one another at the said one of the outer box corners. In addition, the respective outer box wall panels that form the other outer box corners other than said one outer box corner are desirably joined together by respective tear lines along said other corners, and desirably along substantially the entire length of the corner such that the erected outer box is removable from the inner box by moving the outer box wall panels relative to the inner box wall panels so as to sever unsevered tear lines at said other corners.
In one form, the inner and outer box forming structures have respective adjacent front wall panels. The front wall panel of the inner box has a removable display panel portion defined in the inner box front wall panel by, for example, perforations. The display panel portion can be adhered, such as by adhesive, to the outer box front wall panel. In addition, the inner and outer box forming panel structures can have respective back wall panels positioned adjacent to one another with one or more back panel overlays formed in the outer back wall panel. These back panel overlays can be positioned within and can close an associated opening in the outer back wall panel. The back panel overlays can be defined by perforations in the outer box back wall panel. The overlays can be fastened, such as by adhesive, to the outer surface of the inner box back wall panel. The interconnection of the back panel overlays to the inner box back wall panel and the interconnection of display panel portion to the outer box front wall panel retain the inner box and outer box together prior to separation of the outer box front wall from the inner box front wall and the outer box back wall from the inner box back wall. When connected in this manner, upon separation, the display panel portion remains adhered to the outer box front wall panel and the back panel overlays remain adhered to the outer surface of the inner box back wall panel.
As another aspect of an embodiment, respective handle opening overlays in respective end wall panels of the outer box forming structure can be provided. The overlays can be wholly or partially detachable from their respective outer box end wall panels to provide access to respective handle openings through such outer box end wall panels. In addition, inner box end wall panels, each adjacent to a respective one of the outer box end wall panels, can be provided with respective inner box end wall handle opening defining overlays. These inner box opening defining overlays can be fastened to the handle overlays such that outward movement of the handle overlays removes the inner box overlays from the inner box end wall panels. This provides access to inner box handle openings to thereby provide respective opposed end wall handle openings through the outer and inner box end walls for use by a user who is moving the box.
In accordance with another aspect of an embodiment, the outer box panels can be joined together at respective corners by tear lines making these outer box panels easy to remove such as by grabbing and moving the lower edges of such panels outwardly and upwardly relative to the associated adjacent inner box panels. In addition, in one desirable form, the outer box wall panels at one corner are entirely separated. This outer box construction with weakened corners and one separated corner reduces stress on the inner box during manufacturing of the box structure and during erection of the box structure; thereby minimizing the risk of kinking or buckling of the inner box wall panels.
In accordance with an aspect of an embodiment, when the outer box is separated from the inner box, the resulting disassembled outer box, in one desirable form, has an attached display panel portion, attached inner box handle opening overlay portions, and openings where the back wall overlay portions have been removed. The disassembled outer box can be a flat substantially planar structure that can be easily stacked with other such removed outer box structures for recycling purposes. In addition, the respective tear lines and separation at the corners of the outer box result in removable outer box wall panels that do not require box knives or other tools for removal. Desirably the tear lines are formed by perforations. In addition in one embodiment, an elongated slit or slot extends along a major portion, such as one half or more than half, of the tear line to further weaken the corner joints, making the outer panels more easily removable. In addition, at least one corner of the outer box is desirably formed by two panels that meet and that are not joined. Consequently in this embodiment, stress relief is provided when the box structure is erected by the combination of the weakened tear line areas as well as the disconnected corner.

The foregoing and other objects, features, and advantages of the invention will become more apparent from the following detailed description, which proceeds with reference to the accompanying figures. These and other novel and non-obvious features and method acts will become more apparent from the description below and from the drawings. The invention encompasses all such novel and non-obvious method acts and features alone, as well as in all novel and non-obvious combinations and sub-combinations with one another.
Throughout this disclosure, when a reference is made to a first element being coupled to a second element, the term “coupled” is to be construed to mean both direct connection of the elements as well as indirect connection of the elements by way of one or more additional intervening elements. Also, the singular terms “a”, “and”, and “first”, mean both the singular and the plural unless the term is qualified to expressly indicate that it only refers to a singular element, such as by using the phase “only one”. Thus, for example, if two of a particular element are present, there is also “a” or “an” of such element that is present. In addition, the term “and/or” when used in this document is to be construed to include the conjunctive “and”, the disjunctive “or”, and both “and” and “or”. Also, the terms “includes” and “has” have the same meaning as “comprises” and the terms “including” and “having” have the same meaning as “comprising”.
With reference to
In this disclosure, references to top and bottom are simply for purposes of clarifying the description as it is simply a matter of orientation to position one edge of a box upwardly to be a top edge. Similarly, the reference to end walls and side walls are for convenience as they are interchangeable, although typically an end wall would have a width that is shorter than a front and back wall unless the box is of a square cross section.

Because of the tear lines and separated edge at the corners of the assembled outer box, no box knives or other tools are required to disassemble the box structure. In addition, when disassembled, the outer box structure can be substantially planar and flat making it easier to stack for recycling purposes.
Thus, the illustrated inner/outer box forming structures provide a box structure that can be readily erected at, for example, a product packing facility for use in receiving box contents. Also, providing detachable overlay connections between a plurality of the outer box and inner box walls and desirably with at least one such connection between each of the adjacent walls, the outer and inner box components are strengthened and securely held together prior to disassembly of the outer box from the inner display box. Fastening of the inner box handle opening overlays to the outer box handle overlays at the respective end walls of the box structure, fastening one or more outer box back wall overlays to the inner box back wall of the box structure, and fastening a display panel portion of the inner box front wall panel to the outer box front wall panel all assist in maintaining the integrity of the box structure during manufacture, shipment and storage. In addition, this integrity is maintained even if one or more of the tear lines at the corners separate during box structure manufacture. In addition, the combination of tear lines and a separate edge, which separated edge can be replaced by another tear line or temporary connection, facilitates the construction and erection of the box structure without bending or buckling inner box wall panels, while at the same time allowing ready separation of the outer box to leave the intact display box in place for displaying product. In addition, a convenient structure for forming box handles is provided. An outer box structure with tear line corners and one separated corner, has utility apart from the connections to an inner display box.
In view of the many possible embodiments to which the principles of the disclosed invention may be applied, it should be recognized that the illustrated embodiments are only examples of the invention and should not be taken as limiting the scope of the invention. Rather, the scope of the invention is defined by the following claims.
This application claims the benefit of U.S. Provisional Application Ser. No. 62/081,487, entitled BOX STRUCTURE, filed on Nov. 18, 2014.
