Shipping and storage boxes are often provided with a divider that can be inserted into the box for separating individual items from one another. For example, breakable items, such as drinking glasses are often shipped in a box having a divider to prevent the drinking glasses from contacting each other. A divider can also facilitate packing and unpacking of the items within the box by maintaining the items within a defined position relative to one another.
One example of a box and divider system is shown in U.S Publication No. 2008/0283535 to Westrate et al., now U.S. Pat. No. 8,499,956, issued Aug. 6, 2013, which discloses a collapsible container assembly comprising a cell assembly that can be inserted into a box and attached to an interior wall of the box. The box with the cell assembly inside can be folded in a parallelogram motion into a collapsed position which is substantially flat. U.S. Pat. No. 145,137 to Wade discloses an egg carrier comprising a plurality of cells made from strips of pasteboard or thin veneers of wood, which can be used to carry eggs without a surrounding box or container, and which can be folded in a parallelogram motion to a substantially flat condition for transport and storage.
In one aspect, the disclosure relates to a collapsible container assembly includes a collapsible container assembly including a folding container having at four walls, each wall pivotable relative to the adjacent walls at a corresponding corner, the folding container movable between a collapsed position wherein at least two of the four walls are disposed adjacent to one another in parallel and an extended position wherein each of the four walls are perpendicularly arranged relative to each other, and an inside cellular structure attached to at least a portion of each of the four walls, the inside cellular structure comprising a plurality of panels forming a cell assembly, the cell assembly further comprising a plurality of cells in both an X and Y direction with respect to the inside cellular structure, each cell having four cell walls formed by the plurality of panels, at least some of the plurality of cells having two connecting cell walls formed by one of the plurality of panels and another two connecting cell walls formed by an adjacent one of the plurality of panels, each of the connecting cell walls having a curved attachment zone mechanically attached to a curved attachment zone of an adjacent one of the plurality panels. The folding container is further defined by an opposing two of the four corner cells adjacent in the collapsed position, defining a first set of opposing corner cells, wherein the other set of opposing corner cells have a reduced dimension representative of an aggregate size of the attachment zones making up the plurality of panels forming the corner cells such that the attachment zones allow for slack on the inside cellular structure to operably prevent drawing inward of the first set of opposing corner cells adjacent in the collapsed position when the folding container is in the extended position, and wherein the inside cellular structure defines a set of outer perimeter cell walls including the four corner cells, and wherein each of the four corner cells are attached to two of the four walls of the folding container in both the collapsed position and the extended position.
In another aspect, the disclosure relates to a collapsible container assembly including a folding container having four walls movable between a collapsed position and an extended position, and an inside cellular structure comprising a plurality of cells in both an X and Y direction with respect to the inside cellular structure, a series of adjacent continuous panels each mounted to two of the walls of the folding container and to an adjacent wall or an opposing wall of the folding container, each of the series of adjacent continuous panels having a curved attachment portion that is mechanically fastened to an adjacent one of the series of adjacent continuous panels or to one of the four walls of the folding container, whereby the plurality of cells each have four wall portions each formed by the series of adjacent continuous panels between adjacent curved attachment portion. The inside cellular structure defines a set of outer perimeter cell walls having a set of four corner cells, and wherein each of the four corner cells are attached to two of the four walls of the folding container in both the collapsed position and the extended position, an opposing set of two of the four corner cells having a reduced dimension representative of an aggregate size of the curved attachment portions making up the series of adjacent continuous panels between the opposing set of two of the four corner cells such that the curved attachment portions are configured to provide slack on the inside cellular structure in each of the X and Y direction to operably prevent drawing of the folding container inward when the folding container is positioned in the extended position.
In the drawings:
The container 12 can be made out of any suitable rigid or semi-rigid material such as paperboard, cardboard, wood, chipboard, corrugated paper or plastic.
The cell assembly 14 of the container assembly 10 can comprise an interior cellular structure comprising a plurality of cells 30. An example of an interior cellular structure suitable for use according to an embodiment of the invention is the cellular structures disclosed in U.S. Pub. No. 20080283535 to Westrate et al., filed May 15, 2007, now U.S. Pat. No. 8,499,956, issued Aug. 6, 2013, which is hereby incorporated by reference in its entirety.

As used herein, the embodiments of the disclosure according to
While the portion 183 of the cell assembly 114 is described as cut or removed from, embodiments of the disclosure can include manufacturing, forming, or otherwise configuring the cell assembly 114 described herein, wherein the inner superimposed panels 132 include the length of L plus X, but the exterior or outer panels 132A-D have a length of L.
Generally, the second length 194 will be greater than the first length 190, which is greater than the fourth length 200. The third length 196 can, for example, be equal with the second length 194, however, alternative embodiments or alternative sizes of the third length 196 can be included, if not limited by the cell assembly 114 configuration or the container 12. While a four by four cell assembly 114 is illustrated, additional cell assembly configurations can be included (e.g. three by three, five by five, six by six, etc.) wherein the inner cells 130, opposing corner cells 192, 198, and perimeter cells 202 adhere with the sizing examples or wall lengths of the first, second, third, and fourth walls 190, 194, 196, 200. Stated another way, any sizing of a cell assembly can include the opposing corner cells 192, 198, and the perimeter cells 202 (any other outer boundary cells that are not the corner cells 192, 198). Additionally, any cells that are not the corner cells 192, 198 or perimeter cells 202 are located internal to the cell assembly 114 structure, and are inner cells 130.
For ease of understanding, a first example of the cell assembly 114 configuration described in
A container 12 frame has a perimeter lengths of 10″ (L) by 10″ (L), and the cell assembly 114 is configured to include 4 cells by 4 cells. Each of the panels 132, 132A-D can be sized to include an extra dimensional length (X) of 0.125″. The accumulated total lay flat length 180 is 0.25″ (2 times X) longer than the perimeter length. Only the 2 outer corner cells 198 can be shortened to fit into the container 12 frame or fixed perimeter length, so removing 0.125″ from each end 184 will permit the partition to fit into the frame but will make the opposing outer corner cells 198 smaller than is desired, but often workable. In this example, the set of cells 130, 192, 198, 202 can include configurations wherein the resulting first length 190 is 2.5″ (L/4 cells), the second length 194 is 2.625″ (L/4 cells+X; 2.5″+0.125″), the third length 196 is 2.625″ (L/4 cells+X; 2.5″+0.125″), and the fourth length 200 is 2.375″ (L/4 cells−X; 2.5″−0.125″). The total length of an outer perimeter panel 132A-D is 10″ (2.375″+2.5″+2.5″+2.625″), while the total length of an inner panel 132 is 10.25″ (L+2X; 2.625″+2.5″+2.5″+2.625).

Next, in step 404 the cell assembly 114 can be formed by layering and adhering the panels 32, as shown in
In the next step 410, a collapsed, unexpanded cell assembly 114 can be placed on top of the middle sidewalls 16a and 16b. Next, in step 412, the outer sidewalls 16c and 16d can be folded over the cell assembly 114 and adhered to the cell assembly 114 using adhesive that has been applied to the cell assembly 114, creases, and/or the outer sidewalls 16a-d.
In step 414, distal ends of the side walls 16c and 16d can be coupled, such as with additional adhesive or a weld to form a ready to assemble container assembly 10 comprising a partially assembled container 12 and a cell assembly 114. The thus partially assembled, collapsed container 12 can then be expanded and the bottom and/or cover panels 18a-d and 20-a-d can be folded over and secured in a closed position (if needed), using further adhesive, tape or a weld, for example, to fill, ship and store the container assembly 10 in manner similar to that described above for container assembly 10.
The steps in the process of creating the container 12 may be performed in a multitude of different operations, in any order, by a single or multiple processes.
Various materials known in the art can be used to form the cell assembly 114. Commonly used material, such as Kraft paper, is fairly rigid and has minimal or no stretch. Thus, when the cell assembly 114 is made from Kraft paper and connected with the container 12 as described above, as the cell assembly 114 expands, the non-stretching Kraft paper cannot accommodate for the decreased length in the panels 32 between the joints as a result of the curvature of the expanding panels and the width of the joints 34 as the cell assembly 114 is expanded. The extra dimension X, and configuration of the cell assembly 114, as described herein, allows for the expansion of the cell assembly 114 while providing sufficient or adequate slack on the panels 132 to prevent the drawing of the side walls 16a-d of the container 12 inward during expansion. This prevents deformation or uncontrolled collapse of the side walls of the container 12.
Several factors affect the amount of stress applied to the container 12 as the cell assembly 114 expands. Non-limiting examples of these factors include the dimensions of the container, the dimensions of the cells, the type of material the panels are made from, the width of the joint, and the number of joints/number of cells. Increase in the rigidity of the panel material, decrease in the stretch of the panel material, increasing number of cells, and increase in the width of the joint can all increase the amount of stress applied to the container and thus may require different lengths of the dimension X, as well as different lengths of cut or removed portions 184, in order to accommodate the stress.
To the extent not already described, the different features and structures of the various embodiments may be used in combination with each other as desired. That one feature may not be illustrated in all of the embodiments is not meant to be construed that it cannot be, but is done for brevity of description. Thus, the various features of the different embodiments may be mixed and matched as desired to form new embodiments, whether or not the new embodiments are expressly described.
While the invention has been specifically described in connection with certain specific embodiments thereof, it is to be understood that this is by way of illustration and not of limitation. Reasonable variation and modification are possible within the scope of the forgoing disclosure and drawings without departing from the spirit of the invention which is defined in the appended claims.
This application claims the benefit of U.S. Provisional Application Ser. No. 62/292,890 filed Feb. 9, 2016, which is incorporated herein by reference in its entirety.
