Definitions
- Shipping containers for articles, workpieces, auto parts, etc. take a variety of shapes and configurations based on the size and shape of the article or part to be transported.
- automotive parts such as vehicle sheet metal parts, i.e., hoods, deck lids, fenders, door panels, widow glass, etc., come in numerous shapes.
- One type of shipping container for transporting single articles is a corrugated cardboard box having folded over panels which are taped or otherwise secured in a closed position.
- dunnage In the shipping container field, it is known to utilize dunnage to protect articles or parts in shipping containers from movement as well as from contact with the container.
- dunnage typically takes the form of foamed plastic blocks or members which are configured with openings for mounting on one edge of the article or part.
- the dunnage is designed for a snug fit within the shipping container or is fixed in place by means of adhesive, fasteners, etc., to prevent dislodgement and to prevent movement of the article during shipping.
- the dunnage after the part is removed from the shipping container, is returned to the manufacturing facility for reuse. More frequent, the dunnage is removed from the shipping container after the part is removed and then discarded. In this situation, the dunnage represents an added cost to the article or workpiece since new dunnage is required for each article or part.
- the present invention is a shipping container and dunnage which provides advantages over prior article shipping containers and dunnage.
- the shipping container includes a shell including a plurality of panels which can include a base panel, a top panel and opposed side panels.

- Bottom panel 29 further includes a first crease 34 at the intersection of both bottom flanges 32 and bottom panel 29 .
- First crease 34 is formed by a slight deforming compression of substrate 20 along a linear path to facilitate folding or rotating bottom flanges 32 along first crease 34 in an angular orientation to bottom panel 29 as best seen in FIG. 5 and described in detail hereinafter.
- the pair of side panels 44 which are separated by and integral with bottom panel 29 .
- Sides panels 44 are defined by a first side crease 46 and second side crease 48 formed in substrate 20 as previously described.
- First 46 and second 48 side creases are separated by a distance sufficient to accommodate the height of the desired contents and supports described below positioned in shipping container 10 .
- Substrate 20 further includes a first top panel 52 and a second top panel 54 which are integral with the respective side panels 44 as best seen in FIGS. 2 and 5.
- the first 52 and second 54 top panels include a second cutout 56 along the front edge 24 and rear edge 26 as best seen in FIG. 2.
- First top panel 52 includes a first front flange 58 and a first rear flange 59 which are both integral with first top panel 52 .
- first top panel 52 includes a second crease 62 at the intersections of first front 58 and first rear 59 flanges and first top panel 52 .
- first front 58 and the first rear 59 flanges are also separated from an outer edge 64 to permit the respective flanges to fold or rotate in an angular orientation to first top panel 52 as best seen in FIG. 5.
- First front 58 and first rear 59 flanges include a flange edge 66 which is positioned such that the respective flanges do not extend beyond the front edge 24 and rear edge 26 as previously described for bottom flanges 32 .

- Each first support 14 further includes opposing rounded portions 90 which partially obstruct first channel 88 adjacent to inner surface 86 .
- Each first support 14 when used on the side of the component 18 , further includes a 45 degree chamfer at the intersections of the top surface 80 and bottom surface 82 with the outer surface 84 as best seen in FIG. 3. It is understood that chamfers 92 may be at an alternate angle from 45 degrees or may take a rounded or radiused form as opposed to a substantially flat chamfer as shown.
- First supports 14 may also be positioned on the component or hood 18 closer to the center of the front edge of the hood 18 . This would move each front support 14 inward toward the opposed front support 14 from the side located position shown in FIG. 1. In these so called “front edge” mounted positions of first supports 14 , the chamfer 92 will not be required but may still be used to reduce weight and the amount of material needed to form the supports.
- first supports 14 are formed of a lower density material than the rear support 16 described hereafter. This lower density material allows front supports 14 to absorb external forces better without transferring a substantial portion of such forces to the hood 18 .
- first supports 14 are positioned on bottom panel 29 adjacent respective first side creases 46 and are distant from front edge 24 in an approximate position as shown to accommodate an automotive hood 18 .
- additional front supports 14 may be used where desired to support, for example, less rigid components where needed to further support and protect the contents.
- First supports 14 are preferably made from expanded polyurethane or polypropylene cut or molded to the desired shape which, in the described configuration, provides both rigidity to support hood 18 as well as flexibility to separate rounded portions 90 to accept hood 18 and provide a cushion to protect hood 18 .
- Alternate materials include molded or cut expanded polystyrene and other materials that provide rigidity in a block form and substantial cushioning or shock absorption properties while permitting flexibility to insert and remove, for example, an automotive hood 18 into and out of first channel 88 as described and illustrated in FIG. 1.
- shipping container 10 preferably includes, for example, a pair of second supports 16 .
- each rear support 16 has a top surface 102 , a bottom surface 104 , an outer surface 106 , an inner surface 108 , a front side 110 and a rear side 112 .
- Each second support 16 further includes an inner channel opening 114 which is partially open to inner surface 108 and includes an undercut 116 substantially as shown. As illustrated, inner channel opening 114 is positioned and oriented in second support 16 to accept and partially retain a rear corner of an automotive hood 18 as best seen in FIG. 1.
- Second support 16 further includes a 45 degree chamfer at the intersections of top surface 102 and bottom surface 104 with outer surface 106 and extend the entire length between the front 110 and rear 112 sides. It is understood that chamfers 118 may be at an alternate angle from 45 degrees or may take a rounded or radiused form as opposed to a substantially flat chamfer as shown.
- the second support 16 is preferably made from expanded polypropylene or polyurethane cut or molded to the desired shape as substantially shown in FIG. 4. Alternate materials for second support 16 include those previously described for first support 14 . As best seen in FIGS. 1 and 2, second supports 16 are positioned on bottom panel 29 adjacent to the respective first side creases 46 and rear edge 26 as substantially shown.
- the second supports 16 are preferably secured to the shell 12 by a hot melt-type adhesive 124 which is pre-applied in one or two strips or beads or other patterns to surface 104 of the second supports 16 respectively.
- the second supports 16 are then placed in contact with and disposed on bottom panel 29 .
- Alternate methods to secure second supports 16 to the container 10 include adhesives other than a hot melt-type, double-sided adhesive tapes and films, or mechanical fasteners such as staples through substrate 20 into the supports 14 and 16 .
- second supports 200 are not mounted to shell 250 but are moveable within shell 250 .
- second supports In an installed position in shell two, and on installation of the article, for example hood 18 , second supports abut opposing side panels 264 and end panel 266 of the shell lower portion 260
- an automotive hood 18 is mounted in the first supports 14 and second supports 16 .
- the rear corners of hood 18 are positioned in inner channel 114 and more particularly in undercut 116
- the forward, outer edges of hood 18 are positioned in open channel 88 in first supports 14 and are preferably in contact with rounded portions 90 to positively locate and retain hood 18 from lateral movement relative to bottom panel 29 .
- bottom flanges 32 on bottom panel 29 are folded or rotated about first creases 34 to angularly displace bottom flanges 32 with respect to bottom panel 29 to an approximately perpendicular orientation as best seen in FIG. 5.
- first front 58 and first rear 59 flanges on first top panel 52 are similarly displaced in a perpendicular orientation along second creases 62 .
- Second front 60 and second rear 61 flanges of second top panel 58 are also displaced at an angular orientation of approximately 90 degrees to second top panel 54 in a similar manner.
- the two beads of adhesive 124 that were pre-applied on top surface 102 of rear supports 16 are revealed through removal of contact or release paper, not shown, to expose the adhesive as shown in FIGS. 1 - 4 .
- side panel 44 adjacent to second top panel 54 is rotated about first side crease 46 until side panel 44 is approximately 90 degrees with respect to bottom panel 29 .
- side panel 44 is directly adjacent to or in slight contact with outer surfaces 84 and 106 of front supports 14 and rear supports 16 supports.
- Second top panel 54 is then rotated or folded along second side crease 48 to angularly displace second top panel 54 at approximately 90 degrees with respect to side panel 44 thereby placing second top panel 54 in opposing and substantially parallel orientation to bottom panel 29 as best seen in FIG. 6.
- second front 60 and second rear 61 flanges are positioned toward the inside of the container with respect to bottom flanges 32 of bottom panel 29 .
- chamfers 92 (optional) and 118 of front 14 and rear supports 16 respectively are utilized to accommodate variances in substrate 20 and variances in first 46 and second 48 side creases both in position of the creases and radii of the creases when folded.
- Chamfers 92 (optional) and 118 further accommodate variances with respect to the variable positioning or the supports 14 and 16 .
- First top panel 52 and side panel 44 are similarly displaced in angular orientation to bottom panel 29 along first 46 and second 48 side creases at approximately 90 degree angles to position first top panel 52 in overlapping relation to second top panel 54 and in opposing and parallel orientation to bottom panel 29 as best seen in FIG. 6.
- adhesive 124 on the exposed top surfaces 102 of and rear supports 16 adjacent to first top panel 52 is compressed against first top panel 52 thereby securing first top panel 52 in this position similar to second top panel 54 as previously described.
- first front 58 and first rear 59 flanges are positioned between bottom flanges 32 of bottom panel 29 and second front 60 and second rear 61 flanges forming three thicknesses of substrate 20 in overlapping orientation to deter movement of automotive hood 18 along open 88 and inner 114 channels.
- shell 12 optionally further includes markings or text 128 (shown in phantom) on the outer surface of substrate 20 to guide a user in applying strapping bands circumferentially around shipping container 10 to maintain the flanges 32 , 58 , 59 , 60 and 61 in an approximately 90 degree orientation to the top and bottom panels to prevent unwanted longitudinal movement of automotive hood 18 with respect to bottom panel 29 and to prevent further angular disposition of side panels 44 or matchboxing of the assembled shipping container 10 .

Abstract
Description
- This application is a continuation-in-part application of co-pending application Ser. No. 10/340,054 filed Jan. 10, 2003 which claims the benefit of priority of the Jan. 10, 2002 filing date of U.S. provisional patent application serial No. 60/347,432, the contents of which are incorporated herein in their entirety.
- Shipping containers for articles, workpieces, auto parts, etc., take a variety of shapes and configurations based on the size and shape of the article or part to be transported. For example, automotive parts, such as vehicle sheet metal parts, i.e., hoods, deck lids, fenders, door panels, widow glass, etc., come in numerous shapes.
- One type of shipping container for transporting single articles, such as automotive parts, is a corrugated cardboard box having folded over panels which are taped or otherwise secured in a closed position.
- As many automotive parts have a Class A surface finish, extra protection is required to prevent damage to the Class A finish on one or more surfaces of the part by protecting the Class A finish surface of the part from contact with the shipping container itself.
- In the shipping container field, it is known to utilize dunnage to protect articles or parts in shipping containers from movement as well as from contact with the container. Such dunnage typically takes the form of foamed plastic blocks or members which are configured with openings for mounting on one edge of the article or part. The dunnage is designed for a snug fit within the shipping container or is fixed in place by means of adhesive, fasteners, etc., to prevent dislodgement and to prevent movement of the article during shipping.
- Although in certain applications, the dunnage, after the part is removed from the shipping container, is returned to the manufacturing facility for reuse. More frequent, the dunnage is removed from the shipping container after the part is removed and then discarded. In this situation, the dunnage represents an added cost to the article or workpiece since new dunnage is required for each article or part.
- It would be desirable to provide a shipping container and support dunnage which adequately supports and protects an article or workpiece disposed within the shell during storage and shipping, enables easy closure of the shipping container after the article or workpiece is inserted into the container, reduces the number of dunnage pieces which come in contact with or are needed to support the article, increases the structural characteristics, impact strength or shock absorption properties of the dunnage, simplifies the shell of the container and requires a minimal amount of disposable dunnage to reduce the total article manufacturing cost. It would further be desirable to provide dunnage having the above benefits which satisfies the rigorous testing requirements of industrial manufacturers including automobile manufacturers.
- The present invention is a shipping container and dunnage which provides advantages over prior article shipping containers and dunnage.
- In one aspect of the invention, the shipping container includes a shell including a plurality of panels which can include a base panel, a top panel and opposed side panels. At least one first support is adapted to mount over a peripheral edge of an article to support the article within the shell. The first support has a generally C-shape formed of two spaced side legs resiliently extending from one end leg. At least one second support is mounted or positioned within the shell in engagement over a peripheral edge of the particle. The second support has an inner channel opening. The channel is configured for mounting over a corner of a peripheral edge of the article.
- In another aspect, the first support is movably disposed within the shell. The second pair of supports are fixedly mounted within the shell.
- In another aspect, indicia means are provided on the exterior surface of the shell to facilitate to optimum positioning of a banding strap about the shell.
- In another aspect, the shipping container includes a shell having a bottom panel, opposed side panels, each contiguous with one of the bottom panel along a foldable edge, and opposed top panels contiguous with the side panels about a foldable edge. The top panels are foldable into overlapping relationship. A first pair of supports is adapted to mount over a peripheral edge of an article to support the article within the shell. The first pair of supports have a generally C-shape formed of two side legs resiliently extending from one end leg. A second pair of supports is fixedly mounted within the shell. Each of the second pairs of supports has an inner channel opening through one side of the support. The channel is configured for mounting over a corner formed in a peripheral edge of the article.
- In another aspect, the invention is a support block engagable with an article for supporting the article in a shipping container. The block can be the above described C-shaped block, or the block with an inner recess or any combination thereof.
- In one aspect, the at least one first support includes a single first support and the at least one second support includes a pair of second supports. In another aspect, the shipping container and dunnage blocks are configured to support and protect and automobile hood.
- In another aspect, the invention is at least one support or dunnage block having an insert block positioned in the dunnage block to increase the structural integrity and impact absorption properties of the dunnage block. In another aspect, the dunnage block is made from polyurethane, polypropylene, polyethylene or any combination thereof In another aspect, the support or dunnage block is made from polyurethane and the insert block is made from polypropylene.
- The present shipping container and dunnage support provides optimum protection for an article disposed within the container, enables easy closure of the container after the article is inserted into the container and, further, utilizes a minimal amount of disposable dunnage to reduce the total article manufacturing cost.

shell 12 includes asubstrate 20 including afront edge 24, arear edge 26, afirst side edge 27 and asecond side edge 28. Thesubstrate 20 is divided into five sections including abottom panel 29, twoside panels 44, a firsttop panel 52 and a secondtop panel 54. Thesubstrate 20 is generally rectangular in shape in an unfolded or unassembled position as shown in FIG. 2 and is made from die-cut, heavy-duty corrugated cardboard material. It is understood thatsubstrate 20 may alternately be any polygonal shape to fit an application and intended contents and may comprise multiple, non-connected pieces. Thesubstrate 20 may alternately be made from other materials which include similar physical properties to rigidly contain articles. As shown in FIGS. 1 and 5,shipping container 10 is designed and proportioned to securely support and retain anautomotive hood 18. It is understood that theshipping container 10 is adaptable for other contents or goods without deviating from the present invention. - Referring to FIGS. 2 and 5,
bottom panel 29 is generally of square shape and is defined byfront edge 24 andrear edge 26 ofsubstrate 20.Bottom panel 29 includes acutout 30 along both thefront edge 24 andrear edge 26 at the approximate center ofbottom panel 29 as seen in FIG. 2.Bottom panel 29 includes a pair ofbottom flanges 32 that are integral withbottom panel 29 and separated frominner edges 38 definingcutouts 30.Bottom flanges 32 include aflange edge 36 defining a length offlange 32 which does not extend beyond the front 24 or rear 26 edge ofsubstrate 20 and is preferably distant therefrom.Bottom panel 29 further includes afirst crease 34 at the intersection of bothbottom flanges 32 andbottom panel 29.First crease 34 is formed by a slight deforming compression ofsubstrate 20 along a linear path to facilitate folding or rotatingbottom flanges 32 alongfirst crease 34 in an angular orientation tobottom panel 29 as best seen in FIG. 5 and described in detail hereinafter. - The pair of
side panels 44 which are separated by and integral withbottom panel 29.Sides panels 44 are defined by afirst side crease 46 andsecond side crease 48 formed insubstrate 20 as previously described. First 46 and second 48 side creases are separated by a distance sufficient to accommodate the height of the desired contents and supports described below positioned inshipping container 10. -
Substrate 20 further includes a firsttop panel 52 and a secondtop panel 54 which are integral with therespective side panels 44 as best seen in FIGS. 2 and 5. The first 52 and second 54 top panels include asecond cutout 56 along thefront edge 24 andrear edge 26 as best seen in FIG. 2. Firsttop panel 52 includes a firstfront flange 58 and a firstrear flange 59 which are both integral with firsttop panel 52. In a similar fashion to the bottom panel, firsttop panel 52 includes asecond crease 62 at the intersections offirst front 58 and first rear 59 flanges and firsttop panel 52. Thefirst front 58 and the first rear 59 flanges are also separated from anouter edge 64 to permit the respective flanges to fold or rotate in an angular orientation to firsttop panel 52 as best seen in FIG. 5.First front 58 and first rear 59 flanges include aflange edge 66 which is positioned such that the respective flanges do not extend beyond thefront edge 24 andrear edge 26 as previously described forbottom flanges 32. - In a similar fashion to first
top panel 52, secondtop panel 54 includes a secondfront flange 60 and a secondrear flange 61 which are integral with secondtop panel 54. Secondtop panel 54 similarly includes asecond crease 62 along the linear intersections of secondfront flange 60 and secondrear flange 61 with secondtop panel 54.Second front 60 and second rear 61 flanges are separated fromouter edge 64 and include aflange edge 66 similar to that of thefirst front 58 and first rear 59 flanges as previously described. First 52 and second 54 top panels are separated from therespective side panels 44 by second side creases 48 which permit first 52 and second 54 top panels to fold or rotate alongsecond crease lines 48 to angularly displace first 52 and second 54 top panels from therespective side panels 44 as best seen in FIGS. 5 and 6. - It will be understood that the above-described
container 10 is by way of example only. The present invention is also usable with other container constructions including a regular slotted carton, a folded-over lap carton or a telescopic carton. - Referring to FIGS.1-3 and 5,

Eachfirst support 14 further includes opposingrounded portions 90 which partially obstructfirst channel 88 adjacent toinner surface 86. Eachfirst support 14, when used on the side of thecomponent 18, further includes a 45 degree chamfer at the intersections of thetop surface 80 andbottom surface 82 with theouter surface 84 as best seen in FIG. 3. It is understood thatchamfers 92 may be at an alternate angle from 45 degrees or may take a rounded or radiused form as opposed to a substantially flat chamfer as shown. - First supports14 may also be positioned on the component or
hood 18 closer to the center of the front edge of thehood 18. This would move eachfront support 14 inward toward the opposedfront support 14 from the side located position shown in FIG. 1. In these so called “front edge” mounted positions offirst supports 14, thechamfer 92 will not be required but may still be used to reduce weight and the amount of material needed to form the supports. - It will also be understood that the
chamfer 92 for side edge mounted first supports 14 is optional. According to one aspect of the invention, first supports 14 are formed of a lower density material than therear support 16 described hereafter. This lower density material allowsfront supports 14 to absorb external forces better without transferring a substantial portion of such forces to thehood 18. - As best seen in FIGS. 1, 2 and5, first supports 14 are positioned on
bottom panel 29 adjacent respective first side creases 46 and are distant fromfront edge 24 in an approximate position as shown to accommodate anautomotive hood 18. In alternate aspects of the invention, additional front supports 14 may be used where desired to support, for example, less rigid components where needed to further support and protect the contents. First supports 14 are preferably made from expanded polyurethane or polypropylene cut or molded to the desired shape which, in the described configuration, provides both rigidity to supporthood 18 as well as flexibility to separate roundedportions 90 to accepthood 18 and provide a cushion to protecthood 18. Alternate materials include molded or cut expanded polystyrene and other materials that provide rigidity in a block form and substantial cushioning or shock absorption properties while permitting flexibility to insert and remove, for example, anautomotive hood 18 into and out offirst channel 88 as described and illustrated in FIG. 1. - Referring to FIGS. 1, 2 and4,

In this position,side panel 44 is directly adjacent to or in slight contact withouter surfaces rear supports 16 supports. Secondtop panel 54 is then rotated or folded alongsecond side crease 48 to angularly displace secondtop panel 54 at approximately 90 degrees with respect toside panel 44 thereby placing secondtop panel 54 in opposing and substantially parallel orientation tobottom panel 29 as best seen in FIG. 6. In this position,second front 60 and second rear 61 flanges are positioned toward the inside of the container with respect tobottom flanges 32 ofbottom panel 29. In this position, adhesive 124 onrear supports 16 adjacent to secondtop panel 54 is compressed against secondtop panel 54 thereby securing secondtop panel 54 to the rear supports 16 andbottom panel 29. To facilitate easy angular rotation ofside panel 44 and secondtop panel 54 with respect tobottom panel 29, chamfers 92 (optional) and 118 offront 14 andrear supports 16 respectively are utilized to accommodate variances insubstrate 20 and variances in first 46 and second 48 side creases both in position of the creases and radii of the creases when folded. Chamfers 92 (optional) and 118 further accommodate variances with respect to the variable positioning or thesupports - First
top panel 52 andside panel 44 are similarly displaced in angular orientation tobottom panel 29 along first 46 and second 48 side creases at approximately 90 degree angles to position firsttop panel 52 in overlapping relation to secondtop panel 54 and in opposing and parallel orientation tobottom panel 29 as best seen in FIG. 6. In this position, adhesive 124 on the exposedtop surfaces 102 of andrear supports 16 adjacent to firsttop panel 52 is compressed against firsttop panel 52 thereby securing firsttop panel 52 in this position similar to secondtop panel 54 as previously described. In this position,first front 58 and first rear 59 flanges are positioned betweenbottom flanges 32 ofbottom panel 29 andsecond front 60 and second rear 61 flanges forming three thicknesses ofsubstrate 20 in overlapping orientation to deter movement ofautomotive hood 18 along open 88 and inner 114 channels. - Referring to FIG. 6, shell12 optionally further includes markings or text 128 (shown in phantom) on the outer surface of
substrate 20 to guide a user in applying strapping bands circumferentially aroundshipping container 10 to maintain theflanges automotive hood 18 with respect tobottom panel 29 and to prevent further angular disposition ofside panels 44 or matchboxing of the assembledshipping container 10. As shown in FIG. 6, in a fully assembled position, throughopenings 126 exist which provide a free flow of air and circulation inshipping container 10 and around the contents, for example,automotive hood 18. Adhesive 124 on the front andrear supports supports hood 18 and inadvertently exiting theshipping container 10. - Referring to FIGS.7-15, an
