FIELD
Embodiments of the present invention relate generally to the field of point of purchase merchandise shipping and display containers. More particularly, embodiments of the present invention relate to a corrugated, paperboard container that is manufactured in a fold and glue assembly process and that is traditionally provided to an end user in a collapsed or knockdown configuration for setup.
BACKGROUND
Corrugated containers are often made from pieces of flat paperboard stock material that are die cut into shapes that define various panels. The shapes are folded along predefined lines between the panels with at least one overlapping strip or panel that is glued, taped or otherwise affixed to another panel to form an enclosed boundary. The panels are folded and/or glued into place to become the walls of the container. The containers are traditionally provided to product manufacturers and/or retailers in a collapsed or knockdown configuration for storage, handling, and shipping. The manufacturer and/or retailers open the knockdown containers and fold appropriately to utilize the assembled container for packing and/or displaying items positioned therein.
The knockdown containers are typically manufactured by feeding flat die cut sheets through a fold-and-glue machine. The fold-and-glue machine applies adhesive and folds over select panels so that the panels are in the knock-down configuration. One common knockdown container is a pallet container, such as a pallet skirt, that is utilized for encompassing a wooden pallet or stack of wooden pallets to conceal and/or improve aesthetics of items displayed on the pallet(s) in a retail environment. Conventional containers are made from multiple pieces of corrugated material that are attached together by gluing or otherwise securing the pieces together. This adds to the manufacturing and/or assembly complexity, time and costs associated with such items. Therefore, it would be beneficial to provide a container that is made from a single piece of material and/or that does not require the use of glue or other adhesives during manufacturing or assembly.
SUMMARY
Embodiments of the present invention include a pallet skirt comprising a first side-panel section separated from a second side-panel section via a perforated segment extending down a longitudinal centerline of the pallet skirt when in a knockdown configuration. Additionally, each of the first and second side-panel sections includes a side portion fold line extending laterally across the side-panel sections, such that each side-panel section presents two side portions. Furthermore, the pallet skirt includes a pair of end flaps extending along lateral edges of the first and second side-panel sections and separated from the side-panel sections via primary fold lines, with the end flaps being operable to connect the first and second side-panel sections together.
Embodiments of the present invention additionally include a method for making a corrugated pallet skirt comprising: forming a first side-panel section separated from a second side-panel section via a perforated segment that extends down a longitudinal centerline of the pallet skirt when in a knockdown configuration; forming a side portion fold line laterally across each of the first and second side-panel sections, such that each side-panel section presents two side portions; forming end flaps that extend along lateral edges of the first and second side-panel sections; and forming primary fold lines between the end flaps and the side-panel sections.
Embodiments of the present invention additionally include a method of erecting a pallet skirt comprising the steps of providing the pallet skirt in a knockdown configuration, with the pallet skirt including a first side-panel section separated, a second side-panel section, and end flaps that extend along lateral edges of the first and second side-panel sections. The next step includes folding together the first side-panel section and the second side-panel section about a perforated segment. Finally, the method includes the step of extending the first side-panel section and the second side-panel section away from each other such that the pallet skirt forms a rectangular perimeter including four sides.

The embodiments are intended to describe aspects of the invention in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments can be utilized and changes can be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense. The scope of the present invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled.
In this description, references to “one embodiment,” “an embodiment,” or “embodiments” mean that the feature or features being referred to are included in at least one embodiment of the technology. Separate references to “one embodiment,” “an embodiment,” or “embodiments” in this description do not necessarily refer to the same embodiment and are also not mutually exclusive unless so stated and/or except as will be readily apparent to those skilled in the art from the description. For example, a feature, structure, act, etc. described in one embodiment may also be included in other embodiments, but is not necessarily included. Thus, the present technology can include a variety of combinations and/or integrations of the embodiments described herein.
As used herein, the term “longitudinal” generally refers to an orientation or direction relative to an axis of elongation, whereas lateral refers to an orientation or direction that is generally perpendicular to the axis of elongation.
As shown in FIG. 1, embodiments of the present invention include a pallet skirt 10 that is formed from a single, rectangular-shaped piece of corrugated material. In certain embodiments, such corrugated material includes paperboard. Nevertheless, other embodiments provide for the corrugated material to include other similar types of materials, such as cardboard, fiberboard, or the like. The pallet skirt 10 of embodiments of the present invention is capable of being initially provided in a knockdown configuration, such as illustrated in FIG. 2. In such embodiments, the pallet skirt 10 as illustrated has a generally rectangular shape. The pallet skirt 10 includes a first side-panel section 12 and a second side-panel section 14 separated by a perforation/cut line 16 (shown via a pair of parallel dashed lines in FIG. 2) that extends down a longitudinal centerline of the rectangular-shaped piece of corrugated material. As shown in FIG. 2, perforation line 16, does not extend all the way to the opposing ends, 24, of pallet skirt 10, such that side-panel sections 12 and 14 remain connected along each ends 24. In certain embodiments, the perforation line 16 is formed on the pallet skirt 10 by die-cut or other method of creating a perforation. As will be discussed in more detail below, the pallet skirt 10 in its erected configuration generally comprises four sides. Thus, each of the side-panel sections 12, 14 includes two side portions that each present one of the sides when the pallet skirt is in its erected configuration. As illustrated in FIG. 1 and FIG. 2, the two side portions for each of the side-panel sections 12, 14 are separated from one another by side portion fold lines 18. In certain embodiments, such side portion fold lines 18 are created by compressing along a thin line of the corrugated material to define the fold lines. In other embodiments, the fold lines 18 are formed by cutting part way through along the fold line, or in additional embodiments, by cutting all or part way through the fold line at spaced intervals. As such, each of the side portions on a side-panel section 12, 14 are capable of being easily rotated or folded with respect to each other. In certain embodiments, the pallet skirt 10 in an erected configuration is generally square-shaped, such that each of the side portions are generally equivalent in size and the side section fold lines 18 laterally bisect each of the side-panel sections 12, 14. In other embodiments, however, the pallet skirt 10 in an erected configuration has a rectangular shape. In such embodiments, the side portions are not equivalent in size and the side section fold lines 18 are positioned offset from the side-panel sections 12, 14 bisecting lateral axes. The different sizes and shapes of the pallet skirt 10 provide for the pallet skirt to be implemented with pallets of various sizes and shapes.
Additionally, in certain embodiments, each of the first and second side-panel sections 12, 14 have an edge section 20 that extends along longitudinal edges of the pallet skirt 10 (i.e., along long sides of the rectangular-shaped pallet skirt). The edge sections 20 are separated from the side-panel sections 12, 14 by edge section fold lines 22. In certain embodiments, such edge section fold lines 22 are created by compressing along a thin line of the corrugated material to define the fold lines. In other embodiments the fold lines are formed by cutting pad way through along the fold line, or alternatively, by cutting all the way or part way through the fold line at spaced intervals. As such, each of the edge sections 20 on a given side-panel section are capable of being rotated or folded easily with respect to their respective side-panel section 12, 14.
In certain embodiments, the first and second side-panel sections 12, 14 are connected together by a pair of opposing end flaps 24. The end flaps 24 are positioned in some embodiments along lateral edges of the pallet skirt 10 (i.e., along short sides of the rectangular-shaped pallet skirt). The end flaps 24 are connected to the first and second side-panel sections 12, 14 via primary fold lines 26. In certain embodiments, such primary fold lines 26 are created by compressing along a thin line of the corrugated material to define the fold line. In other embodiments, the fold lines are formed by cutting part way through along the fold line, or alternatively, by cutting all the way or part way through the fold line at spaced intervals. As such, each of the end flaps 24 are capable of being rotated or folded easily with respect to the first and second side-panel sections 12, 14, or visa-a-versa. In additional embodiments, the end flaps 24 each include a secondary fold line 28 that separate portions of the end flap that connect to each of the first and second side-panel sections 12,14. In certain embodiments, the secondary fold lines 28 are generally aligned or collinear with the perforated segment 16. Such secondary fold lines 28 are created in some embodiments by compressing along a thin line of the corrugated material to define the fold lines. In other embodiments, the fold lines are formed by cutting part way through along the fold line, or alternatively, by cutting all the way through or part way through the fold line at spaced intervals. As such, each of the end flaps 24 is capable of being rotated or folded easily with respect to each other. Thus, the side-panel sections 12, 14 are held together by the end flaps 24 on the lateral sides of the pallet skirt 10, and the end flaps 24 secure the side-panel sections 12, 14 together in both a knockdown configuration and an erected configuration (i.e., when assembled), as will be discussed in more detail below.
In certain embodiments, the pallet skirt 10 additionally includes two or more cutouts 30 formed through portions of the first and/or second side-panel sections 12, 14. The cutouts 30 are shaped in some embodiments in the form of a rectangle, or in other embodiments, are formed in other shapes, such a circular, oblong, square, triangular, or the like. As will be discussed in more detail below, the cutouts 30 provide for fork members of a forklift tractor to be inserted therethrough, such that the forklift tractor can lift the pallet skirt 10 and its associated pallet without requiring the pallet skirt to be removed from the pallet or otherwise reconfigured in any way.
The pallet skirt 10 is capable of being initially provided in the knockdown configuration (i.e., a generally flat, two-dimensional form), such as illustrated in FIG. 2. From the knockdown configuration, the pallet skirt 10 is capable of being assembled and/or transformed into the erected configuration, such as shown in FIG. 1. In operation, the pallet skirt 10 is assembled by initially folding each of the end flaps 24 about the primary fold lines 26 over the first and second side-panel sections 12, 14, such as illustrated in FIG. 3. Next, as illustrated by FIGS. 4-5, the side-panel sections 12, 14 and the end flaps 24 are then folded about the perforated segment 16 and the secondary fold lines 28 (i.e. about the longitudinal axis of the pallet skirt 10) until the edge sections 20 of each the first and second side-panel sections are adjacent with each other and generally parallel. Thereafter, as illustrated by FIG. 6, the side-panel sections 12, 14 are pulled apart from each other (with section 12 and 14 being completely separated along perforated segment 16), forming a box (square or rectangular, depending upon the dimensions of the side portions of the side-panel sections 12,14), with the side-panel sections being connected to each other by the end flaps 24.
With the pallet skirt 10 in such a configuration, surfaces of each of the end flaps 24 that are adjacent each other and secured together (at the bottom as seen in FIG. 6) by being folded about the secondary fold line 28. In some embodiments, these surfaces are secured together by glue or other adhesives. Nevertheless, in other embodiments, such as illustrated by FIG. 7, the edge sections 20 are folded about the edge section fold lines 22 until they are adjacent with their corresponding side-panel section 12, 14. As such, the edge sections 20 secure the adjacent surfaces of the end flaps 24 together and against a side-panel section 12, 14 without requiring glue or other adhesive. In some embodiments, glue or other adhesive are used for additional bonding.
As Illustrated by FIG. 8, the pallet skirt 10 is secured in the erected configuration and is capable of being positioned over a pallet 32 for securing items therein. For instance, with the pallet skirt 10 positioned over the pallet 32, items are capable of being positioned on the pallet and secured thereon by the sides portions of the side-panel sections 12, 14 of the pallet skirt. Alternatively, the pallet skirt 10 is positioned over pallet 32 after items have been positioned and secured on the pallet 32. As previously described, certain embodiments of the present invention include cutouts 30 positioned along portions of the pallet skirt 10 to allow forks of a forklift tractor to be inserted through the pallet 32 and the pallet skirt to lift the pallet without requiring removal of the pallet skirt from the pallet. In some embodiments, the cutouts 30 are formed via perforation lines, such that material comprising the cutouts 30 are detachably secured to the pallet skirt 10 and are capable of being selectively removed by an end user if desired. In alternative embodiments, the material comprising the cutouts 30 may be left attached if not needed and to allow for improved aesthetics.
Although the invention has been described with reference to the embodiments illustrated in the attached drawing figures, it is noted that equivalents may be employed and substitutions made herein without departing from the scope of the invention as recited in the claims. For instance, in certain embodiments, the pallet side-panel sections 12, 14 of the pallet skirt 10 include supplemental side portion fold lines 34 in addition to the side portion lines 18. As illustrated by FIG. 2, such supplemental side portion fold lines 34 are positioned generally parallel with the side-panel fold lines 18, such that one or more of the side portions of the side-panel sections 12, 14 are capable of being folded about the supplemental fold lines. The supplemental side portion fold lines 34 allow for the pallet skirt 10 in its erected configurations to be quickly folded together in a flat, two-dimensional configuration for easy storage and/or transport. For example, as illustrated by FIG. 9, after removing the pallet skirt 10 from a pallet, the side portions with the supplemental side portion fold lines 34 formed thereon are folded about the supplemental fold lines 34 such that the pallet skirt forms an “x” or an accordion shape. Consequently, the pallet skirt 10 is compressed into a flat, generally two-dimensional configuration that facilitates storage and shipping. Furthermore, in certain embodiments, such folding is performed at a manufacturing location, and the flat, two-dimensional pallet skirt 10 may be transport and unfolded at a later time for use.
