The present invention relates to packaging and, more particularly, to point-of-sale paperboard packaging.
Paperboard packaging is well known in the packaging art. A typical paperboard package is constructed from pre-cut sheets of paperboard (often called “blanks”). A conventional blank is a single, continuous sheet of paperboard having a shape dictated by the number and arrangement of panels included in the package. The blanks are often pre-scored or otherwise configured to define fold lines that facilitate folding of the blank into the desired shape. The blank will typically include one or more retaining flaps that can be used to permanently secure the blank in the folded configuration or to temporarily secure a closure, such as a lid, in the closed position. For example, a conventional paperboard package may include a retaining flap that is attached to another panel by adhesive or fasteners (e.g. staples) to permanently secure the blank in the shape of the package. The use of adhesives and/or fasteners has a number of drawbacks. For example, adhesives and fasteners increase cost and complicate the manufacturing process. Costs are increased not only by the cost of the adhesive and the fasteners, but also by the cost of the equipment required to apply the adhesive or install the fasteners. Additionally, the use of adhesive can have a significant negative impact on the environment. For example, many adhesives utilize solvents and other potentially toxic components. Also, the presence of adhesives can complicate efforts to recycle the paperboard package. Further, the integrity of an adhesive bond can be impacted by delamination of the paperboard, and the strength of a staple bond can be limited by the tear-strength of the paperboard. As a result, in applications where the attachment is required to bear a significant amount of weight, it may be necessary to use more expensive paperboard with greater delamination strength and/or greater tear strength.
In addition to permanent attachments, retaining flaps are also used with temporary attachments. For example, it is often desirable to provide a package with a lid that can be repeatedly opened and closed to selectively provide access to the contents of the package. To provide this functionality, the package may include a top closure with a retaining flap that can be fitted into the package to temporarily hold the top closure in the closed configuration. In this context, the retaining flap may have small slits that interlock with internal flaps that help to hold the top closure in the closed position. These types of temporary joints have limited hold strength and, if used without supplementation, typically prevent the package from being suspended by a hanging tab secured to the top closure because the weight of the package can pull open the top closure. This is a particularly significant drawback in the context of point-of-sale packaging where it is often desirable to suspend packages from a hanging hook.
The present invention provides a point-of-sale paperboard package having a pair of spaced-apart support rails that receive and support one or more packaged articles and a top closure that is secured to the support rails by one or more packaged articles. The top closure may include a pair of retaining flaps that extend adjacent to the support rails and intersect with one or more of the packaged articles. In one embodiment, each retaining flap extends into one of the support rails and is secured to that support rail by a packaged article that extends through the support rail and the retaining flap.
In one embodiment, the product support rails are defined by a series of consecutive panels folded into a tube-like configuration. For example, the product support rails may include a series of panels that are folded into a rectilinear configuration. The panels may be folded to into a rectangular shape, a triangular shape or another hollow shape with a different number of sides. The retaining flaps may extend into the hollow interior of the product support rails. The retaining flaps may define one or more product receiving opening configured to allow the packaged articles to be inserted through the retaining flaps.
In one embodiment, the top closure includes an inner panel that is folded into the space between the support rails. The inner panel may be closely fitted into the space to prevent the support rails from unfolding. The inner panel may include tabs that interlock with corresponding slots in the support rails to hold the inner panel in the folded position between the support rails.
In one embodiment, the package includes a bottom closure with a pair of retaining flaps. The bottom closure is folded into position and secured in the folded position by the retaining flaps, which intersect with one or more of the packaged articles. In one embodiment, a packaged article extends through at least one support rail and at least one retaining flap of the bottom closure.
In one embodiment, the product support rails are held in the folded configuration by the top and bottom closures. For example, in one embodiment, the product support rails include inner panels that are spaced apart from one to define an intermediate rectangular space, and the top and bottom closures each include a rectangular inner panel that is closely fitted into the intermediate rectangular space between the support rails.
In one embodiment, the package includes left and right support rails extending along the left and right edges of the package. The left support rail may include an outer panel, an intermediate panel and an inner panel. The outer panel may be joined to the main panel along a fold line or a score line. The intermediate panel may be joined to the outer panel along a fold line or a score line. The inner panel may be joined to the intermediate panel along a fold line or a score line. The fold line may be defined by essentially any feature intended to facilitate folding along a desired line, such as a score line, a crease line, a cut line or a plurality of spaced-apart cuts or perforations.
In one embodiment, the outer panel of a support rail defines one or more openings configured to receive the article or articles to be packaged. For example, in the context of a package configured to support a set of eight screwdrivers, the outer panel of the left support rail may define four openings that are configured to allow the quillon of the screwdriver handle to be inserted through the outer panel into the product support rail. In this embodiment, the inner panel may have an opening that allows passage of the screwdriver shaft, but not the quillon. As a result, in this embodiment, the quillon can be firmly seated in the hollow interior of the support rail.
In one embodiment, the top closure includes an outer panel, an intermediate panel and an inner panel that are folded to form an end rail extending from the main panel. The inner panel may be fitted into the space between the right support rail and the left support rail and include end tabs that are inserted into corresponding slots in the right support rail and the left support rail. The outer panel also includes a pair of retaining flaps that extend into the hollow interior of the support rails where they are intersected by packaged articles passing through the support rails.
In one embodiment, the package may include a central beam that provides supplemental support for packaged articles. The central beam may be disposed in the space between the left and right support rails where it can be intersected by packaged articles. The support beam may be formed by additional panels that extend from the inner panels of the left and right support rails. The top and bottom closures may include slots that are fitted over opposite ends of the central beam. Although centered in the illustrated embodiment, the beam may be disposed off-center, if desired.
The present invention provides a simple and effective package that is easily and inexpensively manufactured and assembled without the need for adhesives or fasteners to secure the retaining flaps. As a result, the package can be completely biodegradable and recyclable, and is therefore environmentally friendly. Given that adhesives and fasteners are unnecessary, the package can be manufactured and assembled without the need for complex and expensive adhesive applicators, tape applicators or fastener installation equipment. The package is also durable allowing the packaged articles, rather than adhesives, tapes or fasteners, to intersecure the closures and the support rails. This can be particularly beneficial in packages that are hung from a display hook as the weight of the packaged articles is borne predominantly by that interconnection. The package allows articles to be easily arranged in a staggered configuration that reduces the footprint and overall size of the package.
The package is particularly well suited for use in packaging a set of screwdrivers. The package allows the quillon to be firmly seated in one support rail with the screwdriver shaft extending across the package through the opposite support rail. If desired, the handle, a majority of the shaft and the screwdriver tip can be made accessible to the consumer. The package can support screwdrivers of different sizes and with different length shafts. For example, the same package can hold stubby screwdrivers as well as full-length screwdrivers. If desired, screwdrivers may be fitted into the package from opposite sides and may be arranged in staggered rows to improve fill and reduce package size. The width and length of the package can be varied to allow packaging of a different types and different numbers of screwdrivers. If desired, a central beam can be incorporated into the package to accommodate an even wider range of articles, such as screwdrivers with a wide range of shaft lengths.
These and other objects, advantages and features of the invention will be more fully understood and appreciated by reference to the description of the current embodiment and the drawings.

Package 10 will now be described in more detail with reference to
As noted above, the package 10 generally includes a main panel 12, a left support rail 14, a right support rail 16, a top closure 18, a bottom closure 20 and a hanging tab 88. Depending on the application, either major surface of the main panel 12 may form the front surface of the package 10. For example, the major surface of the main panel 12 facing the screwdrivers may be the front surface of the package 10 in applications where it is desirable for the packaged articles to face forward. As an alternative example, the major surface of the main panel 12 facing away from the screwdrivers may be the front surface of the package 10 in applications where it is desirable to have a larger front surface capable of bearing graphics and other printed material. In the illustrated embodiment, the main panel 12 is generally rectangular, but its shape may vary from application to application, as discussed below in more detail. For example, the number and relative length of the sides of the main panel 12 may vary from application to application.
Referring now to
In the illustrated embodiment, the left support rail 14 generally includes an outer panel 32, an intermediate panel 34 and an inner panel 36. When assembled, the outer panel 32 of this embodiment extends substantially perpendicularly to the main panel 12. The size, shape and configuration of the outer panel 32 may vary. For example, the width of the outer panel 32 may vary to control the depth of the left support rail 14 to correspond with the article(s) to be packaged. As another example, the angle between the outer panel 32 and the main panel 12 may vary. The outer panel 32 includes a series of openings 33a-d and 35a-c configured to receive the packaged articles (See
The intermediate panel 34 extends inwardly from the outer panel 32 in a direction substantially perpendicular to the outer panel 32 and substantially parallel to the main panel 12. In this embodiment, the intermediate panel 34 is a generally rectangular plane and is of sufficient width to accommodate the quillons 100 of the packaged screwdrivers. The size, shape and configuration of the intermediate panel 34 may vary. For example, the width of the intermediate panel 34 may vary to control the spacing between the inner panel 32 and the outer panel 36. As another example, the angle between the outer panel 32 and intermediate panel 34 may vary to control the shape of the left support rail 14. Further, the shape of the intermediate panel 34 may be varied. For example, the intermediate panel 34 need not have a rectangular periphery. As another example, the intermediate panel 34 need not be planar, but instead may have curvature or otherwise be non-planar.
The inner panel 36 extends toward the main panel 12 at an angle of approximately ninety degrees from the intermediate panel 34. In this embodiment, the inner panel 36 is a generally rectangular plane that terminates at or in close proximity to the main panel 12. The size, shape and configuration of the inner panel 36 may vary. For example, the width of the inner panel 36 may vary. As another example, the angle between the inner panel 36 and the main panel 12 may vary to control the shape of the left support rail 14. Further, the shape of the inner panel 36 may be varied. For example, the inner panel 36 need not have a rectangular periphery. As another example, the inner panel 36 need not be planar, but instead may have curvature or otherwise be non-planar. The inner panel 36 of the illustrated embodiment defines a plurality of shaft openings 37a-g configured to receive the shafts 104 of packaged screwdrivers S1-S4 and S6-S8. To accommodate these screwdrivers, the inner panel 36 defines shaft openings 37a-g arranged in a staggered pattern. The number, size, shape, pattern/arrangement and configuration of the shaft openings 37a-g may vary from application to application. For example, shaft openings 37a-c are defined by a small circular opening and a concentric pair of cuts formed in an “X” pattern, while shaft openings 37d-g are defined by a pair of cuts formed in an “X” pattern. In the illustrated embodiment, the inner panel 36 includes interlocking features that help to secure the top and bottom closures 18 and 20 in place between the left and right support rails 14 and 16. The illustrated inner panel 36 defines a first retention slot 39 configured to receive a corresponding tab 89 extending from the inner panel 74 of the top closure 18 and a second retention slot 41 configured to receive a corresponding tab 126 extending from the inner panel 124 of the bottom closure 20. The illustrated tab/slot arrangement is optional, and it may be eliminated or varied in alternative embodiments.
In the illustrated embodiment, the right support rail 16 extends along the right edge of the main panel 12 and is largely a mirror image of the left support rail 14 differing primarily in the arrangement of openings configured to receive the packaged articles. Although the left and right support rails 14 and 16 are essentially mirror-images of one another in the illustrated embodiment, the right support rail 16 may differ from the left support rail 14. For example, the left support rail 14 and right support rail 16 may vary in size, shape, configuration and/or number of panels. These variations may be dictated by the article(s) to be packaged. Given the similarity between the right and left support rails 14 and 16, the right support rail 16 will not be separately described in as much detail as the left support rail 14. It should be noted that the description of the left support rail 14, including the illustrated embodiment and all alternative embodiments, applies to the right support rail 16, except as otherwise provided. The right support rail 16 of the illustrated embodiment generally includes an outer panel 52, intermediate panel 54 and an inner panel 56. As with outer panel 32, the outer panel 52 of the right support rail 16 defines a plurality of openings 53a-d and 55a-c configured to receive the quillons 100 of the screwdrivers S5-S8 that enter the package 10 from the right side and the shafts 104 of select screwdrivers S2-S4 that enter the package 10 from the left side (See
As noted above, the top end of the package 10 includes a top closure 18 having a pair of retaining flaps 22 and 24 that extend into the left support rail 14 and right support rail 16 where they are intersected by one or more packaged articles (in this case, screwdrivers S1 and S4). In the illustrated embodiment, the top closure 18 folds into the space between the left support rail 14 and the right support rail 16 to help prevent the left support rail 14 and the right support rail 16 from unfolding. Referring now to
In the illustrated embodiment, the retaining flaps 22 and 24 extend from opposite edges of the outer panel 70. As shown, each retaining flap 22 and 24 is generally rectangular and defines an opening 92 and 94 configured to receive a portion of a packaged article. In this embodiment, each retaining flap 22 and 24 is configured to intersect with the shaft of a different screwdriver. More specifically, retaining flap 22 intersects with the shaft of screwdriver S1 and retaining flap 24 intersects with the shaft of screwdriver S5. In this embodiment, the screwdrivers S1 and S5 are stubby screwdrivers, which each have a shaft 104 that extends through only one support rail 14 or 16. When packaging full length screwdrivers at the top of the package 10, each retaining flap 22 and 24 may be configured to intersect with two screwdrivers. In such embodiments, each retaining flap 22 and 24 can define an additional opening positioned to align with the shaft of the corresponding screwdrivers. In this embodiment, the retaining flaps 22 and 24 extend into the interior of the support rails 14 and 16. In alternative embodiments, the retaining flaps 22 and 24 may extend outside of the support rails 14 and 16. For example, the retaining flaps may alternatively extend along the internal surface of the inner panels 36 and 56.
The intermediate panel 72 extends from the outer panel 70 at an angle of approximately 90 degrees. This angle may vary from application to application. The illustrated intermediate panel 72 is a generally rectangular plane, but its size, shape and configuration may vary. For example, the intermediate panel 72 may have a non-rectangular periphery. As another example, the intermediate panel 72 may have curvature or otherwise have a non-planar shape.
The inner panel 74 is generally rectangular and extends from the intermediate panel 72 at an angle of approximately 90 degrees. The inner panel 74 terminates at or adjacent to the main panel 12. The angle between the inner panel 74 and the intermediate panel 72 may vary from application to application. The illustrated inner panel 74 is generally rectangular, but its shape may vary. Tabs 89 and 90 extend from opposite edges of the inner panel 74. As noted above, the tabs 89 and 90 are configured to be fitted into corresponding slots 39 and 61 in the left support rail 14 and the right support rail 16.
In this embodiment, the package 10 is intended for use as a point-of-sale package that can be suspended from a display hook at the point of sale. To facilitate this, the package 10 includes a hanging tab 88 that protrudes upwardly from the outer panel 70 of the top closure 18 to provide a structure for hanging the package 10 from a display hook. In this embodiment, the hanging tab 88 is separately manufactured and installed through the hanging tab slot 86 in the top closure 18. Referring now to
In the illustrated embodiment, the bottom closure 20 is essentially a mirror image of the top closure 18, except as described and shown in the drawings. The bottom closure 20 generally includes an outer panel 120, an intermediate panel 122, an inner panel 124 and retaining flaps 26 and 28. Unlike the top closure 18, the outer panel 120 of the bottom closure 20 does not include a slot for receiving a hanging tab. The outer panel 120 is otherwise essentially identical to outer panel 70. The intermediate panel 122 of the bottom closure 20 is essentially identical to intermediate panel 72. The inner panel 124 of the bottom closure 20 is essentially identical to inner panel 74, and includes tabs 126 and 128 configured to be interfitted with the left and right support rails 14 and 16. The shape of the retaining flaps 26 and 28 and the configuration of the openings 130a-d in the retaining flaps 26 and 28 vary from those of top closure 18. For example, in this embodiment, retaining flaps 26 and 28 are longer than retaining flaps 22 and 24, and they include angled corners 27 and 29. The angled corners 27 and 29 may prevent the retaining flaps 26 and 28 from interfering with installation of screwdriver S3 in the package 10. In this embodiment, each retaining flap 26 and 28 includes a pair of opening 130a-d that allow the bottom two screwdrivers S4 and S8 to be fitted through the retaining flaps 26 and 28. More specifically, in this embodiment, the package 10 includes two screwdrivers S4 and S8 with full left shafts seated in the bottom two positions. The shafts 104 of these bottom two screwdrivers S4 and S8 extend through the openings 130a-d in both retaining flaps 26 and 28.
As noted above, the package 10 is formed primarily from a single one-piece paperboard blank 30, which is described in more detail below (See
Referring now to
In the illustrated embodiment, each of the left and right support rails 14 and 16 is formed by a number of consecutive panels that are folded to form into a hollow rectilinear structure. Referring now to blank 30, the left support rail 14 generally includes an outer panel 32, intermediate panel 34 and an inner panel 36. The names of these panels are selected to correspond to the relative position of these panels in the folded package 10. The outer panel 32 is joined to the main panel 12 along a fold line 38. For purposes of disclosure, the term “fold line” is used to refer to any and all features that may be provided to a paperboard blank to facilitate or assist in forming a fold. The term should be broadly interpreted to include fold lines, score lines, cut lines, partial cut lines, perforations, intermittent score lines, intermittent cut lines, lines of weakening and the like. The intermediate panel 34 is joined to the outer panel 32 along a fold line 40. The inner panel 36 is joined to the intermediate panel 34 along a fold line 42. The outer panel 32 defines a plurality of quillon openings 33a-d configured to allow the quillons 100 of screwdrivers S1-S4 to be inserted into the left support rail 14. In this embodiment, the size and shape of each quillon opening 33a-d generally corresponds with the cross-sectional size and shape of the portion of the handle 102 that is aligned with quillon opening 33a-d when the screwdriver is properly seated in the package 10. As can be seen, quillon opening 33a has a different shape that quillon openings 33b-d. This is because screwdriver S1 (which is fitted into quillon opening 33a) has a different shape than screwdrivers S2-S4 (which are fitted into quillon openings 33b-d). More specifically, in this embodiment, screwdriver S1 is a stubby screwdriver that is more triangular in cross-section at the interface location, while screwdrivers S2-S4 are full length screwdrivers that are more circular in cross-section at the interface location. Each quillon opening 33a-d may include a series of associated cuts that allow the paperboard around the opening 33a-d to flex and bend as needed to allow insertion of the quillon 100 through the opening 33a-d. For example, in the context of the screwdrivers S1-S8, the quillon 100 is larger than the portion of the handle 102 that will be seated in the quillon opening 33a-d. Accordingly, the paperboard blank around the quillon opening 33a-d is cut to define flaps or fingers that are capable of flexing or bending to accommodate passage of the quillon 100. Additional cuts may be formed at the base of the flaps to along controlled bending of the paperboard about those additional cuts. The inherent resiliency of the paperboard will allow the flaps or finger to close about the handle 102 after the quillon 100 has passed. The outer panel 32 also defines a plurality of shaft openings 35a-c configured to receive the shafts 104 of screwdrivers S6-S8. Similarly, the inner panel 36 defines a plurality of shaft openings 37a-g configured to receive the shafts 104 screwdrivers S1-S4 and S6-S8. The size and shape of each shaft opening 35a-c and 37a-g may vary depending on the article to be seated in that hole. For example, with smaller diameter shafts, the shaft openings may include one or more cuts that allow the article to pass through the panel. In the illustrated embodiment, shaft openings 35a-b and 37d-g are defined by a pair of cuts that intersect in an “X” pattern. With larger diameter shafts, the shaft openings may be defined by the removal of material from the panel. In the illustrated embodiment, shaft openings 35c and 37a-c are defined by a circular die cut aligned with a pair of cuts that intersect in an “X” pattern. The inner panel 36 may also define a pair of slots 39 and 41 configured to receive tabs 89 and 126 extending from the top closure 18 and the bottom closure 20. This tab and slot arrangement may help to retain the inner panel 36 in the desired final position.
The right support rail 16 generally includes an outer panel 52, intermediate panel 54 and an inner panel 56. The outer panel 52 is joined to the main panel 12 along a fold line 58. The intermediate panel 54 is joined to the outer panel 52 along a fold line 60. The inner panel 56 is joined to the intermediate panel 54 along a fold line 62. The outer panel 52 defines a plurality of quillon openings 53a-d configured to allow the quillons 100 of screwdrivers S5-S8 to be inserted into the right support rail 16. The outer panel 52 also defines a plurality of shaft openings 55a-c configured to receive the shafts 104 of screwdrivers S2-S4. The inner panel 56 defines a plurality of shaft openings 57a-g configured to receive the shafts 104 screwdrivers S2-S8. The inner panel 56 also defines a pair of slots 61 and 63 configured to receive tabs 90 and 128 extending from the top closure 18 and the bottom closure 20.
In this embodiment, the quillon openings 33a-d and 53a-d are configured to hold the screwdrivers S1-S8 in the desired orientation. For example, the quillon openings can be configured to hold the screwdrivers so that the logos presented on the handles are facing forward. In the illustrated embodiment, the screwdrivers have handles that are generally triangular in cross-section. As shown, the quillon openings 33a-d are positioned adjacent to the main panel 12 so that a flat surface of each handle 102 seated in the left support rail 14 is engaged with and extends along the main panel 12. Interaction between the flat surface of the handle 102 and the flat surface of the main panel 12 helps to resist rotation of the screwdriver once packaged. Similarly, the quillon openings 53a-d are positioned adjacent to the intermediate panel 54 so that a flat surface of each handle 102 seated in the right support rail 16 is engaged with and extends along the intermediate panel 54. As noted above, the blank 30 includes a series of cuts arranged around each quillon opening 33a-d and 53a-d to provide flaps or fingers arranged in a triangular configuration to accommodate insertion of a triangularly-shaped object in the desired orientation. As such, the position of the quillon openings 33a-d and 53a-d relative to the main panel 12 and intermediate panel 54, and the triangular configuration of the flaps or fingers cooperatively facilitate insertion of the screwdrivers into the package in the correct orientation. In the illustrated embodiment, the flaps or fingers are configured to be slightly longer that would be required to correspond with the external shape of the handle 102, such that the inner edges of the flaps or fingers are slightly smaller than the cross-sectional shape of the handle 102. In use, insertion of the screwdriver into the support rails 14 and 16 causes the flaps or fingers to bend inwardly to allow passage of the quillon 100. After passage of the quillon 100, the flaps or fingers spring back toward their original position. Because the flaps or fingers are slightly longer, they engage the handle 102 before fully returning to their original position. As a result, the flaps or fingers remain at a slight bend, which help to resists removal of the screwdriver from the package 10. In alternative applications, the quillon openings, including the flaps/fingers, may be adapted or modified to correspond with the article(s) to be packaged in the package. For example, the flaps or finger may be adapted or modified to correspond with the size, shape and configuration of the packaged article(s) to assist in shepherding insertion of the article(s) into the package in the desired orientation and/or to hold the packaged article(s) in the desired orientation. More specifically, the quillon openings may be surrounded by an alternative arrangement of cuts that form a different number, size or arrangement of flaps or fingers. For example, the quillon opening may include four flaps or fingers the correspond with an article that has four sides. As another example, the flaps or fingers may be shortened to make it easier to remove the article(s) from the package or lengthened to make it more difficult to remove the packaged article(s).
The top and bottom closures 18 and 20 are configured to fold into the space between the left and right support rails 14 and 16. When folded into these positions, the top and bottom closure 18 and 20 hold the left and right support rails 14 and 16 in the folded configuration. The top closure 18 generally includes an outer panel 70, intermediate panel 72, an inner panel 74 and a pair of retaining flaps 22 and 24. The outer panel 70 is joined to the main panel 12 along a fold line 76. The intermediate panel 72 is joined to the outer panel 70 along a fold line 78. The inner panel 74 is joined to the intermediate panel 72 along a fold line 80. The retaining flaps 22 and 24 are joined to the outer panel 70 along fold lines 82 and 84. The outer panel 70 of the top closure 18 is generally rectangular and defines an elongated slot 86 configured to receive a hanging tab 88 (described in more detail below) for hanging the package 10 from a display hook or similar structure. In this embodiment, the slot 86 is generally centrally located, but its position may vary from application to application, as desired. In applications that do not include a hanging tab, the slot 86 may be eliminated. The inner panel 74 includes a pair of tabs 89 and 90 that extend from opposite ends to extend into corresponding slots 39 and 61 in the inner panels 36 and 56 of the left and right support rails 14 and 16. In this embodiment, the retaining flaps 22 and 24 are configured to extend into the left and right support rails 14 and 16 a sufficient distance to be intersected by two packaged screwdrivers S1 and S5. To facilitate insertion of the screwdrivers S1 and S4, each retaining flap 22 and 24 includes an opening 92 and 94 of sufficient size to accommodate the corresponding screwdriver shaft. As perhaps best shown in
In this embodiment, the bottom closure 20 is similar to the top closure 18, except that retaining flaps 26 and 28 differ somewhat from retaining flaps 22 and 24. The bottom closure 20 generally includes an outer panel 120, intermediate panel 122, an inner panel 124 and a pair of retaining flaps 26 and 28. The outer panel 120 is joined to the main panel 12 along a fold line 150. The intermediate panel 122 is joined to the outer panel 120 along a fold line 152. The inner panel 124 is joined to the intermediate panel 122 along a fold line 154. The retaining flaps 26 and 28 are joined to the outer panel 120 along fold lines 156 and 158. The inner panel 124 includes a pair of tabs 126 and 128. In this embodiment, the retaining flaps 26 and 28 each define two openings 130a-d of sufficient size to receive the shafts 104 of the two bottom-most screwdrivers S4 and S8.

The package 10 is formed by folding the various panels of the blank 30 into the desired shape. Although there is some flexibility in the order in which the panels are folded, one method for folding the blank 30 into the package 10 will be described. As noted above, the package 10 is formed from package blank 30 and hanging tab blank 138. In this method, the hanging tab blank 138 is formed first by folding the blank 138 along its centerline to move the exposed panels 140 and the retaining panels 142 into side-by-side relationship. The exposed panels 140 are then fitted through slot 86 in the outer panel 70 of the top closure 18. The retaining panels 142 may be folded away from each other to lay flat along the outer panel 70. The hanging tab 88 may alternatively be folded and inserted into the top closure 18 at essentially any time prior to folding the inner panel 74 of the top closure 18 down into its final position. The package blank 30 may next be folded to complete formation of the package 10. In this method, the left and right support rails are formed first and then the top and bottom closures are formed. Before the left and right support rails 14 and 16 are formed, however, the top and bottom closures 18 and 20 are partially folded so that the left and right support rails 14 and 16 can be formed around the retaining flaps 22, 24, 26 and 28. More specifically, in this embodiment, the outer panels of the top and bottom closures 18 and 20 are folded up approximately ninety degrees. The retaining flaps 22, 24, 26 and 28 are then folded inwardly approximately ninety degrees so that are disposed in the space that will be surrounded by the left and right support rails 14 and 16. The outer panel of the left support rail 14 may then be folded upward approximately ninety degrees. The intermediate panel of the left support rail 14 is then folded inwardly approximately ninety degrees. The inner panel of the left support rail 14 is then folded downwardly approximately ninety degrees to form a rectangular rail that entraps the retaining flaps 22 and 26. The same process may then be repeated to fold the right support rail 16 to form a rectangular rail that entraps the retaining flaps 24 and 28.
The top and bottom closures 18 and 20 can then be folded to complete the package 10. More specifically, the intermediate panel of the top closure 18 may be folded inwardly approximately ninety degrees, and then the inner panel of the top closure 18 may be folded downwardly approximately ninety degrees into the space between the left and right support rails 14 and 16. The tabs 89 and 90 on opposite ends of the inner panel are fitted into slots 39 and 61 in the inner panel of the left support rail 14 and the inner panel of the right support rail 16. The process may be repeated for the bottom closure 20. More specifically, the intermediate panel of the bottom closure 20 may be folded inwardly approximately ninety degrees, and then the inner panel of the bottom closure 20 may be folded downwardly approximately ninety degrees into the space between the left and right support rails 14 and 16. The tabs 126 and 128 on opposite ends of the inner panel are fitted into slots 41 and 63 in the inner panel of the left support rail 14 and the inner panel of the right support rail 16.

Although the package 10 is described without any adhesive or other fasteners securing the retaining flaps 22, 24, 26 and 28, the package 10 may be provided with adhesive and/or fasteners, as desired. For example, the package 10 may include adhesive that joins the retaining flaps to the left and right support rails. As another example, tape, staples or other forms of fasteners may be used to secure the retaining flaps to the left and right support rails.
