## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a continuation application of U.S. patent application Ser. No. 13/243,404, filed Sep. 23, 2011, entitled “BLANK ASSEMBLY FOR FORMING A REINFORCED, STACKABLE TRAY CONTAINER”, the disclosure of which is hereby incorporated herein by reference in its entirety.


BACKGROUND OF THE INVENTION
The embodiments described herein relate generally to a tray container for shipping and displaying products and, more particularly, to a blank assembly for forming a reinforced tray container capable of nesting within another such tray container when the tray containers are stacked.
At least some known tray containers are used for shipping and displaying products. More specifically, such tray containers include side walls that are open to display the product therein and enable access to the products through the opening in the side walls. However, end walls of such containers are solid and do not enable viewing of or access to the products. As such, the containers can only be used in a limited number of orientations when used for display.
Further, with respect to the known trays, a shipping pad is usually placed in the opening of the side walls to prevent damage to the products during shipping and/or provide additional support to the container during shipping. This shipping pad is a separate piece that must be shrink wrapped, or otherwise coupled, to the known tray during shipping and is not part of the tray wall. At least one of the known tray containers includes a center divider.
Additionally, at least some of the known trays are not knocked-down flat type containers and, thus, requires numerous steps and/or a machine to erect the tray. These known trays also do not include an automatically-erecting bottom wall having a substantially double-overlapping bottom wall.

The following detailed description illustrates the disclosure by way of example and not by way of limitation. The description clearly enables one skilled in the art to make and use an exemplary container, describes several embodiments, adaptations, variations, alternatives, and use of the blanks and/or containers, including what is presently believed to be the best mode of carrying out the disclosure.
A tray container formed from a single sheet of material and methods for constructing the container are described herein. The tray container may be constructed from a plurality of blanks of sheet material using at least one machine. In one embodiment, the blanks are fabricated from a cardboard material. The blanks, however, may be fabricated using any suitable material, and therefore are not limited to a specific type of material. In alternative embodiments, the blanks are fabricated using cardboard, plastic, fiberboard, paperboard, foamboard, corrugated paper, and/or any suitable material known to those skilled in the art and guided by the teachings herein provided.
In an example embodiment, the tray container includes at least one marking thereon including, without limitation, indicia that communicates the product stored in the tray, a manufacturer of the product, and/or a seller of the product. For example, the marking may include printed text that indicates a product's name and briefly describes the product, logos and/or trademarks that indicate a manufacturer and/or seller of the product, and/or designs and/or ornamentation that attract attention. “Printing,” “printed,” and/or any other form of “print” as used herein may include, but is not limited to including, ink jet printing, laser printing, screen printing, giclée, pen and ink, painting, offset lithography, flexography, relief print, rotogravure, dye transfer, and/or any suitable printing technique known to those skilled in the art and guided by the teachings herein provided. In another embodiment, the tray is void of markings, such as, without limitation, indicia that communicates the product, a manufacturer of the product and/or a seller of the product.
The tray container described herein is formed from a blank assembly including a tray blank, two side insert blanks, and two end insert blanks. Referring now to the drawings, FIG. 1 is a top view of an exemplary tray blank 100 of sheet material for forming a tray container, such as a container 700 (shown in FIGS. 8-10). Blank 100 has a first or interior surface 102 and an opposing second or exterior surface 104. Further, blank 100 defines a first edge 106 and an opposing second edge 108. In one embodiment, blank 100 includes, in series from first edge 106 to second edge 108, a first end panel assembly 110, a first side panel assembly 112, a second end panel assembly 114, a second side panel assembly 116, and a glue panel 118 coupled together along preformed, generally parallel, fold lines 120, 122, 124, and 126, respectively. Fold lines 120, 122, 124, and/or 126, as well as other fold lines and/or hinge lines described herein, may include any suitable crease, line of weakening, and/or line of separation known to those skilled in the art and guided by the teachings herein provided.
More specifically, first end panel assembly 110 extends from first edge 106 to fold line 120, first side panel assembly 112 extends from first end panel assembly 110 along fold line 120, second end panel assembly 114 extends from first side panel assembly 112 along fold line 122, second side panel assembly 116 extends from second end panel assembly 114 along fold line 124, and glue panel 118 extends from second side panel assembly 116 along fold line 126 to second edge 108. In the exemplary embodiment, fold line 120 and fold line 124 each include a pair of parallel lines of weakness to facilitate forming container 700 from blank 100 using a machine. More specifically, fold lines 120 and 124 allow for insert blanks 400 and 500 (shown in FIGS. 2 and 4) to be glued to blank 100 and for assembled blanks 100, 400, and 500 to be formed into a knocked-down flat container.
In the exemplary embodiment, each panel assembly 110, 112, 114, and 116 includes a respective free top edge 128, 130, 132, or 134. Free top edges 128, 130, 132, and 134 define a slight arc from first edge 106 to fold line 126 such that, when container 700 is formed, side and end walls of container 700 taper outward from a bottom edge toward a top edge, as described in more detail below. Similarly, each panel assembly 110, 112, 114, and 116 includes a respective bottom fold line 136, 138, 140, or 142. Fold lines 136, 138, 140, and 142 define a slight arc from first edge 106 to fold line 126 such that, when container 700 is formed, side and end walls of container 700 taper outward from a bottom edge toward a top edge, as described in more detail below. In the exemplary embodiment, each top edge 128, 130, 132, and 134 is substantially parallel to a respective bottom fold line 136, 138, 140, or 142, and top edges 128, 130, 132, and 134 and bottom fold lines 136, 138, 140, and 142 are each substantially linear. Because each bottom fold line 136, 138, 140, and 142 is shorter than a respective top edge 128, 130, 132, or 134, blank 100 has the slight arc from first edge 106 to fold line 126 with respect to longitudinal axis 144 of blank 100.
Glue panel 118 is wider toward a bottom edge 146 than at a top edge 148 such that second edge 108 is substantially perpendicular to a longitudinal axis 144 of blank 100 to facilitate assembling blanks 100, 400, and 500 using a machine. For example, a width W is the widest portion of glue panel 118. Alternatively, glue panel 118 has any suitable shape that enables container 700 to be formed from blank 100.
A first bottom end panel assembly 150 extends from first end panel assembly 110 along fold line 136, a first bottom side panel 152 extends from first side panel assembly 112 along fold line 138, a second bottom end panel 154 extends from second end panel assembly 114 along fold line 140, and a second bottom side panel assembly 156 extends from second side panel assembly 116 along fold line 142. When container 700 is formed from blank 100, fold line 136 defines a bottom edge of first end panel assembly 110 and an end edge of bottom end panel assembly 150; fold line 138 defines a bottom edge of first side panel assembly 112 and a side edge of first bottom side panel 152; fold line 140 defines a bottom edge of second end panel assembly 114 and an end edge of second bottom end panel 154; and fold line 142 defines a bottom edge of second side panel assembly 116 and a side edge of second bottom side panel assembly 156.
First end panel assembly 110 includes top edge 128 that is substantially parallel to fold line 136 and slightly longer than fold line 136. First end panel assembly 110 further includes an end panel 158, an inner end panel 160, and a pad panel 162. More specifically, inner end panel 160 and pad panel 162 are defined in end panel 158. In the exemplary embodiment, inner end panel 160 is defined by a horizontal hinge line 164, a horizontal perforated line 166, and two generally vertical perforated lines 168 and 170. Horizontal perforated line 166 separates pad panel 162 from inner end panel 160. Pad panel 162 is further defined by top edge 128 and two generally vertical tear lines 172 and 174 that are substantially co-linear with perforated lines 168 and 170, respectively. Tear lines 172 and 174 are configured to enable pad panel 162 to be removed from first end panel assembly 110 by a user, as described in more detail below. Alternatively, tear lines 172 and/or 174 are other than co-linear with perforated lines 168 and/or 170. In a particular embodiment, pad panel 162 includes indicia (not shown), such as an “X” or an “O”, embossed and/or printed on exterior surface 104 thereof to facilitate stacking a plurality of containers 700. In the exemplary embodiment, perforated lines 168 and 170 and tear lines 172 and 174 diverge from the bottom toward top edge 128. In an alternative embodiment, perforated lines 168 and 170 and tear lines 172 and 174 have any suitable configuration that enables container 700 to function as described herein.

Side edges 408 and 412 are substantially perpendicular to top edge 406 and bottom edge 410. Angled corners are defined between bottom edge 410 and each side edge 408 and 412. Alternatively, blank 400 includes other than angled corners, such as curved corners, or omits angled corners.
In the exemplary embodiment, blank 400 includes a reinforcing side panel 414, a pad panel 416, cutouts 418 and 420, and a removable tab 422. Cutout 418 is defined by side cut lines 424 and 426, a top cut line 428, and a bottom cut line 430. Top cut line 428 and bottom cut line 430 are substantially parallel to top edge 406 and bottom edge 410. Side cut line 424 is generally perpendicular to bottom cut line 430, but includes a first portion that is oriented at an obtuse angle 432 to bottom cut line 430 such that cutout 418 widens from bottom cut line 430 upwards. A second portion of side cut line 424 angles inwardly toward top cut line 428 such that a largest width of cutout 418 is located at an intersection of the two portions of side cut line 424. The shape of cut line 424 is configured to enable inner side panel 180 (shown in FIG. 1) to be inserted through cutouts 418 and 420 when container 700 is erected. More specifically, the shape provides room for error when positioning insert blank 400 on first side panel assembly 112. Alternatively, cut line 424 has any suitable configuration that enables insert blank 400 to function as described herein. In the exemplary embodiment, cutout 420 is substantially a mirror image of cutout 418 and is defined by side cut lines 424 and 426, top cut line 428, and bottom cut line 430.
Removable tab 422 is defined between cutouts 418 and 420 by cut lines 426. Removable tab 422 is further defined by a slit score line 434 and a perforated line 436. Slit score line 434 is substantially co-linear with cut lines 428, and perforated line 436 is substantially co-linear with cut lines 430. Tab 422 is configured to enable the machine to sense insert blank 400 as insert blank 400 is coupled to tray blank 100. More specifically, a photo eye of the machine senses tab 422 to maintain a count. Further, tab 422 is configured to prevent jamming of the machine as insert blanks 400 and blanks 100 pass through the machine. More specifically, tab 422 facilitates preventing material from being inserted through cutout 418 and/or cutout 420 as the machine couples insert blank 400 to tray blank 100 and/or forms the knocked-down flat container from the assembled blank, as described in more detail below. In an alternative embodiment, tab 422 is omitted and insert blank 400 includes one continuous cutout rather than cutouts 418 and 420.
In the exemplary embodiment, pad panel 416 is defined by cut lines 428 and slit score line 434 along a bottom edge thereof. Pad panel 416 is further defined by tear lines 438 and 440 extending between top edge 406 and cut lines 424. Tear lines 438 and 440 are configured to enable pad panel 416 to be removed from insert blank 400 by a user. More specifically, tear lines 438 and 440 are configured to substantially, or at least partially, align with tear lines 192 and 194 (shown in FIG. 1), respectively, such that pad panel 416 and pad panel 182 (shown in FIG. 1) can be removed together. Indicia 442 can be embossed on pad panel 416 to facilitate assembling blanks 100 and 400 into the formed blank. For example, indicia 442 on pad panel 416 corresponds to indicia 198 (shown in FIG. 1) on pad panel 182 to facilitate coupling insert blank 400 to first side panel assembly 112 for assembling the formed blank.
A bottom portion 444 of reinforcing side panel 414 is at least partially defined by bottom edge 410, cut lines 430, and perforated line 436. A first side portion 446 of reinforcing side panel 414 is at least partially defined by side edge 408, cut line 424, tear line 438, and top edge 406. Similarly, a second side portion 448 of reinforcing side panel 414 is at least partially defined by side edge 412, cut line 424, tear line 440, and top edge 406. Side portions 446 and 448 are continuous with bottom portion 444.
Cutouts 418 and 420, tab 422, and pad panel 416 are symmetric about a centerline 450 thereof. In the exemplary embodiment, centerline 450 of cutouts 418 and 420, tab 422, and pad panel 416 is slightly offset from a centerline 452 of blank 400 toward second side edge 412 of blank 400 to correspond to a shape of first side panel assembly 112 caused by the slight arc of top edges 128, 130, 132, and 134 (all shown in FIG. 1) and bottom fold lines 136, 138, 140, and 142 (all shown in FIG. 1) of tray blank 100. Alternatively, centerline 450 is substantially aligned with centerline 452 or offset toward first side edge 408 of blank 400.
When manufacturing blank 400, a plurality of first side insert blanks 400 can be formed from one sheet of material, as shown in FIG. 3.

Second side insert blank 500 is configured to be coupled to interior surface 102 (shown in FIG. 1) of second side panel assembly 116 (shown in FIG. 1). Insert blank 500 has a first or interior surface 502 and an opposing second or exterior surface 504. Further, blank 500 includes a free top edge 506, a first free side edge 508, a free bottom edge 510, and a second free side edge 512. In the exemplary embodiment, top edge 506 and bottom edge 510 are substantially parallel to each other, and side edges 508 and 512 are only partially parallel to each other. More specifically, first side edge 508 includes a first portion that is substantially perpendicular to bottom edge 510 and a second portion that is angled inwardly from the first portion toward second side edge 512. The second portion is connected to top edge 506 at an obtuse angle 514. Second side edge 512 includes a first portion that extends from bottom edge 510 at an obtuse angle 516 and a second portion that connects to top edge 506 at a right angle.
The second portion of side edge 508 and the first portion of side edge 512, i.e., the orthogonal portions, are configured to correspond to the shape of second side panel assembly 116. The first portion of side edge 508 and the second portion of side edge 512, i.e., the perpendicular portions, are configured to enable the machine to properly align insert blank 500 with second side panel assembly 116 even though a longitudinal axis 324 (shown in FIG. 1) of second side panel assembly 116 is not parallel to longitudinal axis 144 (shown in FIG. 1) of tray blank 100. More specifically, longitudinal axis 324 is orthogonal to blank longitudinal axis 144. Additionally, longitudinal axes of first end panel assembly 110 and second end panel assembly 114 are orthogonal to longitudinal axis 144. In an alternative embodiment, the perpendicular portions are omitted from side edges 508 and/or 512 and side edges 508 and/or 512 are orthogonal to edges 506 and/or 510. In the exemplary embodiment, angled corners are defined between bottom edge 510 and each side edge 508 and 512. Alternatively, blank 500 includes other than angled corners, such as curved corners, or omits angled corners.
In the exemplary embodiment, blank 500 includes a reinforcing side panel 518, a pad panel 520, cutouts 522 and 524, and a removable tab 526. Cutout 522 is defined by side cut lines 528 and 530, a top cut line 532, and a bottom cut line 534. Top cut line 532 and bottom cut line 534 are substantially parallel to top edge 506 and bottom edge 510. Side cut line 530 is at an obtuse angle 536 to bottom cut line 534, and side cut line 528 includes a first portion that is oriented at an obtuse angle 538 to bottom cut line 534 such that cutout 522 widens from bottom cut line 534 upwards. A second portion of side cut line 528 angles inwardly toward top cut line 532 such that a largest width of cutout 522 is located at an intersection of the two portions of side cut line 528. The shape of cut line 528 is configured to enable inner side panel 224 (shown in FIG. 1) to be inserted through cutouts 522 and 524 when container 700 is erected. More specifically, the shape provides room for error when positioning insert blank 500 on second side panel assembly 116. Alternatively, cut lines 528 have any suitable configuration that enables insert blank 500 to function as described herein. In the exemplary embodiment, cutout 524 is substantially a mirror image of cutout 522, except for cut line 530, and is defined by side cut lines 528 and 530, top cut line 532, and bottom cut line 534. More specifically, cut line 530 of cutout 524 is substantially parallel to cut line 530 of cutout 522 and is at an acute angle 540 to bottom cut line 534. Alternatively, cut lines 530 have any suitable configuration that enables blank 500 to function as described herein.
Removable tab 526 is defined between cutouts 522 and 524 by cut lines 530. Removable tab 526 is further defined by a slit score line 542 and a perforated line 544. Slit score line 542 is substantially co-linear with cut lines 532, and perforated line 544 is substantially co-linear with cut lines 534. Tab 526 is configured to enable the machine to sense insert blank 500 as insert blank 500 is coupled to tray blank 100. More specifically, the photo eye of the machine senses tab 526 to maintain a count. Further, tab 526 is configured to prevent jamming of the machine as insert blanks 500 and blanks 100 pass through the machine. More specifically, tab 526 facilitates preventing material from being inserted through cutout 522 and/or cutout 524 as the machine couples insert blank 500 to tray blank 100 and/or forms the knocked-down flat container from the assembled blank, as described in more detail below. In an alternative embodiment, tab 526 is omitted and insert blank 500 includes one continuous cutout rather than cutouts 522 and 524.
In the exemplary embodiment, pad panel 520 is defined by cut lines 532 and slit score line 542 along a bottom edge thereof. Pad panel 520 is further defined by tear lines 546 and 548 extending between top edge 506 and cut lines 528 and 532. Tear lines 546 and 548 are configured to enable pad panel 520 to be removed from insert blank 500 by a user. More specifically, tear lines 546 and 548 are configured to substantially, or at least partially, align with tear lines 236 and 238 (shown in FIG. 1), respectively, such that pad panel 520 and pad panel 226 (shown in FIG. 1) can be removed together. Indicia 550 can be embossed on pad panel 520 to facilitate assembling blanks 500 and 100 into the formed blank. For example, indicia 550 on pad panel 520 corresponds to indicia 242 (shown in FIG. 1) on second side panel assembly 116 to facilitate coupling insert blank 500 to second side panel assembly 116 for assembling the formed blank. In the exemplary embodiment, top edge 506 of pad panel 520 includes a pair of notches 552 configured to visually differentiate insert blank 500 from insert blank 400. Alternatively, pad panel 520 does not include notches 552 defined therein.
A bottom portion 554 of reinforcing side panel 518 is at least partially defined by bottom edge 510, cut lines 534, and perforated line 544. A first side portion 556 of reinforcing side panel 518 is at least partially defined by side edge 508, cut line 528, tear line 546, and top edge 506. Similarly, a second side portion 558 of reinforcing side panel 518 is at least partially defined by side edge 512, cut line 528, tear line 548, and top edge 506. Side portions 556 and 558 are continuous with bottom portion 554.
In the exemplary embodiment, a centerline 560 of cutouts 522 and 524, tab 526, and pad panel 520 is slightly offset from a centerline 562 of blank 500 toward second side edge 512 of blank 500 to correspond to a shape of second side panel assembly 116 caused by the slight arc of top edges 128, 130, 132, and 134 (all shown in FIG. 1) and bottom fold lines 136, 138, 140, and 142 (all shown in FIG. 1) of tray blank 100. Alternatively, centerline 560 of is substantially aligned with centerline 562 or offset toward first side edge 508 of blank 500.

FIG. 6 is a top view of an exemplary end insert blank 600 of sheet material for forming container 700 (shown in FIGS. 8-10). End insert blank 600 is configured to be coupled to, or positioned adjacent, interior surface 102 (shown in FIG. 1) of each end panel assembly 110 and 114 (shown in FIG. 1). Insert blank 600 has a first or interior surface 602 and an opposing second or exterior surface 604. Further, blank 600 includes a free top edge 606, a first free side edge 608, a free bottom edge 610, and a second free side edge 612. A first reinforcing end assembly 614 is partially defined by top edge 606 and side edges 608 and 612, and a second reinforcing end assembly 616 is partially defined by bottom edge 610 and side edges 608 and 612. Reinforcing end assemblies 614 and 616 are symmetric across a fold line 618 that horizontally bisects blank 600. As such, first reinforcing end assembly 614 is described below for clarity; however, it should be understood that the description also applies to second reinforcing end assembly 616.
First reinforcing end assembly 614 includes a reinforcing end panel 620 having a cutout 622 and a pad panel 624 defined therein and having a stacking flap 626 or 628 extending from each side edge 630 and 632 thereof A fold line 634 or 636 partially defines side edge 630 and 632, respectively, of reinforcing end panel 620. In the exemplary embodiment, cutout 622 is defined by a pair of side cut lines 638 and 640, a top cut line 642, and a bottom cut line 644. Side cut lines 638 and 640 diverge from each other from bottom cut line 644 to top cut line 642 such that a shape of cutout 622 generally corresponds to a shape of inner end panel 160 and/or 204 (shown in FIG. 1). Bottom cut line 644 includes two downwardly sloping portions 646 and 648 and a substantially horizontal portion 650. Downwardly sloping portions 646 and 648 are configured to narrow a bottom portion 652 of reinforcing end panel 620 adjacent side cut lines 638 and 640. Such narrowing of bottom portion 652 removes material from lower corners 654 of cutout 622 to enable inner end panel 160 or 204 to be folded over bottom portions 652 when container 700 is erected and to reduce stress on inner end panel 160 or 204 when inner end panel 160 or 204 is folded over, as described in more detail below. Top cut line 642 defines a pair of notches 656 configured to facilitate a user's removable of pad panels 624 from end insert 1012 (shown in FIG. 13A), as described in more detail below.
Pad panel 624 is defined by top cut line 642, a pair of tear lines 658 and 660, and fold line 618. Pad panels 624 are connected at fold line 618, and fold line 618 includes a pair of cutouts 662 that are configured to facilitate a user's removable of pad panels 624 from container 700. Tear lines 658 and 660 extend between fold line 618 and a respective cut line 638 or 640. Tear lines 658 and 660 are configured to enable pad panel 624 to be removed from insert blank 600 by a user. In a particular embodiment, tear lines 658 and 660 each include a cut portion 664 that extends from cut line 638 or 640. In the exemplary embodiment, tear lines 658 and 660 are configured to substantially, or at least partially, align with tear lines 172 and 174 (shown in FIG. 1), respectively, or tear lines 216 and 218 (shown in FIG. 1), respectively, such that pad panels 624 and pad panel 162 (shown in FIG. 1) or pad panels 624 and pad panel 206 (shown in FIG. 1) can be removed together.
A first stacking flap 626 extends from fold line 634 to side edge 608. First stacking flap 626 is further defined by fold line 618 and a free bottom edge 666. First stacking flap 626 has a width at fold line 618 that is approximately equal to a width of a first side portion 668 of reinforcing end panel 620 such that, when folded 180° about fold line 634, first stacking flap 626 does not overlap pad panel 624 and/or cutout 622. First stacking flap 626 of first reinforcing end assembly 614 is connected to first stacking flap 626 of second reinforcing end assembly 616 along fold line 618. A relief cutout 670 is defined at the intersection of fold line 618 and fold lines 634 to facilitate rotating stacking flaps 626 about fold lines 634, as described in more detail below.
A second stacking flap 628 extends from fold line 636 to side edge 612. Second stacking flap 628 is further defined by fold line 618 and a free bottom edge 672. Second stacking flap 628 has a width at fold line 618 that is approximately equal to a width of a second side portion 674 of reinforcing end panel 620 such that, when folded 180° about fold line 636, second stacking flap 628 does not overlap pad panel 624 and/or cutout 622. Second stacking flap 628 of first reinforcing end assembly 614 is connected to second stacking flap 628 of second reinforcing end assembly 616 along fold line 618. Relief cutout 670 is defined at the intersection of fold line 618 and fold lines 636 to facilitate rotating stacking flaps 628 about fold lines 636, as described in more detail below.
First side portion 668 of reinforcing end panel 620 is at least partially defined by side edge 608, cut line 638, tear line 658, fold line 634, and fold line 618. Similarly, second side portion 674 of reinforcing end panel 620 is at least partially defined by side edge 612, cut line 640, tear line 660, fold line 636, and fold line 618. Side portions 668 and 674 are continuous with bottom portion 652.
When manufacturing end insert blank 600, a plurality of end insert blanks 600 can be formed from one sheet of material, as shown in FIG. 7.
FIG. 8 is a perspective view of an exemplary tray container 700 formed a blank assembly shown in FIGS. 1-7. FIG. 9 is a top view of an end portion of container 700. The blank assembly includes tray blank 100 (shown in FIG. 1), first side insert blank 400 (shown in FIG. 2), second side insert blank 500 (shown in FIG. 4), and a pair end insert blanks 600 (shown in FIG. 6). Container 700 is shown in an erect configuration 702 in FIG. 8. Referring to FIGS. 1, 2, 4, 6, and 8, container 700 includes a first end wall 704, a first side wall 706, a second end wall 708, a second side wall 710, and a bottom wall 712 that define a cavity 714 of container 700.
First end wall 704 includes first end panel assembly 110, glue panel 118, and a first end insert blank 600. A first end window 716 is defined in first end wall 704 by cutouts 622 of end insert blank 600 and an opening formed by folding inner end panel 160 over bottom portions 652 of reinforcing end panel 620, as described in more detail below. In erect configuration 702, end wall 704 includes end panels 158 and 620 and glue panel 118, and pad panels 162 and pad panels 624 are included in first end wall 704. First end wall 704 further includes a ledge 715 defined by a top edge 717 of pad panels 624, reinforcing end panels 620, and stacking flaps 626 and 628 formed by fold line 618. More specifically, stacking flaps 626 and 628 bias reinforcing end panels 620 and pad panels 624 away from interior surface 102 of first end panel assembly 110 toward cavity 714. However, inner end panel 160 being wrapped about bottom portions 652 and/or free side edges 408 and 512 of side inserts 400 and 500, respectively, force reinforcing end panels 620 and pad panels 624 toward first end panel assembly 110. As such, reinforcing end panels 620 and pad panels 624 are substantially perpendicular to bottom wall 712 while first end panel assembly 110 is at an obtuse angle with respect to bottom wall 712. Accordingly, cavity 714 is a substantially rectangular prism, rather than having the shape of an inverted truncated pyramid.
First side wall 706 includes first side panel assembly 112 and first side insert blank 400. A first side window 718 is defined in first side wall 706 by cutouts 418 and 420 of insert blank 400, a opening formed by removing tab 422 from insert blank 400, and an opening formed by folding inner side panel 180 over bottom portion 444 of reinforcing side panel 414, as described in more detail below.

The ledge is similar to ledge 715 and is defined by top edge 717 of pad panels 624, reinforcing end panels 620, and stacking flaps 626 and 628 formed by fold line 618. More specifically, stacking flaps 626 and 628 bias reinforcing end panels 620 and pad panels 624 away from interior surface 102 of second end panel assembly 114 toward cavity 714. However, inner end panel 204 being wrapped about bottom portions 652 and/or free side edges 412 and 508 of side inserts 400 and 500, respectively, force reinforcing end panels 620 and pad panels 624 toward second end panel assembly 114. As such, reinforcing end panels 620 and pad panels 624 are substantially perpendicular to bottom wall 712 while second end panel assembly 114 is at an obtuse angle with respect to bottom wall 712. Accordingly, cavity 714 is a substantially rectangular prism, rather than having the shape of an inverted truncated pyramid.

Corner columns 740, 742, 744, and 746 are configured to allow a second container 700 to be partially nested within container 700 and to support the second container thereon.
FIG. 11 is a schematic view of an exemplary method 800 for assembling blanks 100, 400, and 500 (shown in FIGS. 1-5) into a formed or assembled blank 802. In a particular embodiment, method 800 is performed using a machine, such as a TANABETM TRI FEEDERTM machine manufactured by Alliance Machine Systems International, LLC (“Tanabe” and “Tri Feeder” are trademarks of Alliance Machine Systems International, LLC of Spokane, Wash., USA). As discussed above, several features of blanks 100, 400, and/or 500 enable the machine to properly align blanks with each other and glue blanks to each other.
Referring to FIGS. 1, 2, 4, and 11, method 800 includes positioning 804 side insert blanks 400 and 500 with respect to tray blank 100. More specifically, first side insert blank 400 is positioned with respect to first side panel assembly 112 such that pad panel 416 is substantially, or at least partially, aligned with pad panel 182. As such, tear lines 438 and 440 are substantially, or at least partially, aligned with tear lines 192 and 194, respectively, and inner side panel 180 is substantially, or at least partially, aligned with cutouts 418 and 420 and tab 422. Similarly, second side insert blank 500 is positioned with respect to second side panel assembly 116 such that pad panel 520 is substantially, or at least partially, aligned with pad panel 226. As such, tear lines 546 and 548 are substantially, or at least partially, aligned with tear lines 236 and 238, respectively, and inner side panel 224 is substantially, or at least partially, aligned with cutouts 522 and 524 and tab 526. Alignment marks 200 and/or 244 can be used to facilitate aligning insert blanks 400 and/or 500 with a respective side panel assembly 112 or 116.
Insert blanks 400 and 500 are then coupled 806 to tray blank 100. More specifically, exterior surface 404 of first insert blank 400 is coupled to interior surface 102 of first side panel assembly 112 using, for example, an adhesive. In the exemplary embodiment, reinforcing side panel 414 is coupled to first side panel 178 and pad panel 416 is coupled to pad panel 182. Similarly, exterior surface 504 of second insert blank 500 is coupled to interior surface 102 of tray blank 100 using, for example, an adhesive. More specifically, reinforcing side panel 518 is coupled to second side panel 222 and pad panel 520 is coupled to pad panel 226. Assembled blank 802 can then be formed into a knocked-down flat container 902 (shown in FIG. 12).
FIG. 12 is a schematic view of an exemplary method 900 for forming a knocked-down flat container 902 from assembled blank 802 (shown in FIG. 11). Knocked-down flat container 902 is similar to container 700 (shown in FIGS. 8-10) in the knocked-down flat configuration. However, in FIG. 12, windows 718, 720, 722, and 724 (all shown in FIG. 8) and/or access openings 750, 752, 754, and 756 (all shown in FIG. 10) have not yet been formed in knocked-down flat container 902. Rather, windows 718, 720, 722, and 724 and/or access openings 750, 752, 754, and 756 are formed in a subsequent erecting method. Method 900 can be performed by a folder gluer machine positioned downstream from the machine used to form assembled blank 802. For example, the folder gluer machine can be a J&L Specialty Folder Gluer manufactured by Alliance Machine Systems International, LLC. Features of blanks 100, 400, and 500 described above facilitate preventing jamming and/or misalignment as the folder gluer machine forms knocked-down flat container 902 from assembled blank 802.
Referring to FIGS. 1, 2, 4, and 12, method 900 includes rotating 904 bottom panels 248, 152, 154, and 300 toward a respective panel assembly 110, 112, 114, or 116. More specifically, first bottom end panel assembly 150 is rotated 904 about fold line 136 toward first end panel assembly 110 such that interior surface 102 of first bottom end panel assembly 150 is adjacent interior surface 102 of first end panel assembly 110. First bottom side panel 152 is rotated 904 about fold line 138 toward first side panel assembly 112 such that interior surface 102 of first bottom side panel 152 is adjacent interior surface 402 of first insert blank 400. Second bottom end panel 154 is rotated 904 about fold line 140 toward second end panel assembly 114 such that interior surface 102 of second bottom end panel 154 is adjacent interior surface 102 of second end panel assembly 114. Second bottom side panel assembly 156 is rotated 904 about fold line 142 toward second side panel assembly 116 such that interior surface 102 of second bottom side panel assembly 156 is adjacent interior surface 502 of second insert blank 500. In an alternative embodiment, first bottom end panel assembly 150 is rotated toward first end panel assembly 110 after coupling panel 302 is coupled to second bottom end panel 154.
In the exemplary embodiment, coupling panel 250 is rotated 906 about fold line 252 toward first bottom end panel 248 such that exterior surface 104 of coupling panel 250 is adjacent exterior surface 104 of first bottom end panel 248. Similarly, coupling panel 302 is rotated 906 about fold line 304 toward second bottom side panel 300 such that exterior surface 104 of coupling panel 302 is adjacent exterior surface 104 of second bottom side panel 300. Alternatively, coupling panel 250 is rotated 906 about fold line 252 after coupling panel 302 is coupled to second bottom end panel 154.
In the exemplary embodiment, adhesive is applied 908 to interior surface 102 of coupling panel 302 and/or to exterior surface 104 of second bottom end panel 154. Second side panel assembly 116 and second bottom side panel assembly 156 are rotated 910 about fold line 124 toward second bottom end panel 154 to couple coupling panel 302 to second bottom end panel 154. More specifically, the adhesive on interior surface 102 of coupling panel 302 contacts exterior surface 104 of second bottom end panel 154 as panel assemblies 116 and 156 are rotated 910 about fold line 124. As such, interior surface 102 of coupling panel 302 is coupled to exterior surface 104 of second bottom end panel 154. Panel assemblies 116 and 156 can be held and/or pressed in position until the adhesive sets.
Adhesive is applied 912 to interior surface 102 of coupling panel 250 and/or to exterior surface 104 of first bottom side panel 152. Adhesive is also applied 912 to exterior surface 104 of glue panel 118 and/or interior surface 102 of first end panel 158. First end panel assembly 110 and first bottom end panel assembly 150 are rotated 914 about fold line 120 toward first bottom side panel 152 to couple coupling panel 250 to first bottom side panel 152 and to couple glue panel 118 to first end panel 158. More specifically, the adhesive on interior surface 102 of coupling panel 250 contacts exterior surface 104 of first bottom side panel 152 and the adhesive on exterior surface 104 of glue panel 118 contacts interior surface 102 of first end panel 158 as panel assemblies 110 and 150 are rotated 914 about fold line 120. As such, interior surface 102 of coupling panel 250 is coupled to exterior surface 104 of first bottom side panel 152, and exterior surface 104 of glue panel 118 is coupled to interior surface 102 of first end panel 158. Panel assemblies 110 and 150 can be held and/or pressed in position until the adhesive sets.
Knocked-down flat container 902 formed using method 900 includes first end wall 704, first side wall 706, second end wall 708, and second side wall 710. Bottom wall 712 is collapsed and received within walls 704, 706, 708, and 710. First corner 724 and third corner 728 are formed at fold lines 120 and 124, respectively, and second corner 726 (shown in FIG. 8) and fourth corner 730 (shown in FIG. 8) are not yet formed. Knocked-down flat container 902 can be shipped, stored, and/or erected into container 700.
FIGS. 13A and 13B are a schematic view of an exemplary method 1000 for erecting and stacking container 700 (shown in FIG. 8) from knocked-down flat container 902 (shown in FIG. 12). Method 1000 can be performed manually by, for example, a customer that has obtained knocked-down flat container 902. As such, a machine is not required to erect container 700 from knocked-down flat container 902.
Referring to FIGS. 1, 2, 4, 6, 8, 9, 13A, and 13B, method 1000 includes forcing 1002 first corner 724 toward third corner 728. As corners 724 and 728 are forced 1002 toward each other, second corner 726 and fourth corner 730 begin forming at fold lines 122 and 126 and bottom panels 248, 152, 154, and 300 begin to rotate downward away from interior surfaces 102 of walls 704, 706, 708, and 710.
Bottom panels 248, 152, 154, and 300 are then forced 1004 downwardly about fold lines 136, 138, 140, and 142, respectively, to form bottom wall 712. More specifically, tabs 278 are inserted into slots 296 and 298 to secure first bottom side panel 152 over other bottom panels 150, 154, and 156 such that bottom wall 712 is secured in position. Bottom wall 712 is generally perpendicular to walls 704, 706, 708, and 710. Cavity 714 of container 700 is formed, and container 700 can be filled with products 1006; however, in the exemplary embodiment, windows 716, 718, 720, and 722 are defined in walls 704, 706, 708, and 710, respectively, before products 1006 are positioned 1022 within cavity 714.
In the exemplary embodiment, inner side panels 180 and 224 are rotated toward cavity 714 to define 1008 windows 718 and 722 in side walls 706 and 710, respectively. More specifically, first inner side panel 180 is rotated about hinge line 184 toward cavity 714 through cutouts 418 and 420. At least a bottom edge of removable tab 422 is separated from reinforcing side panel 414 at perforated line 436 to allow inner side panel 180 to be rotated through cutouts 418 and 420. Removable tab 422 can be removed before, during, or after inner side panel 180 is rotated through cutouts 418 and 420. In the exemplary embodiment, removable tab 422 is removed as inner side panel 180 is rotated. Alternatively, removable tab 422 is removed when container 700 is transitioned from erect configuration 702 to display configuration 748 (shown in FIG. 10). In the exemplary embodiment, tab 196 is coupled within slot 266 to secure inner side panel 180 in position to form first side lip 734. An opening formed by rotating inner side panel 180 defines 1008 window 718 in first side wall 706.
Similarly, second inner side panel 224 is rotated about hinge line 228 toward cavity 714 through cutouts 522 and 524. At least a bottom edge of removable tab 526 is separated from reinforcing side panel 518 at perforated line 544 to allow inner side panel 224 to be rotated through cutouts 522 and 524. Removable tab 526 can be removed before, during, or after inner side panel 224 is rotated through cutouts 522 and 524. In the exemplary embodiment, removable tab 526 is removed as inner side panel 224 is rotated. Alternatively, removable tab 526 is removed when container 700 is transitioned from erect configuration 702 to display configuration 748. In the exemplary embodiment, tab 240 is coupled within slot 294 to secure inner side panel 224 in position to form second side lip 738. An opening formed by rotating inner side panel 224 defines 1008 window 722 in second side wall 710.
End insert blanks 600 are then formed 1010 into end inserts 1012 by rotating first reinforcing end assembly 614 toward second reinforcing end assembly 616 about fold line 618. Interior surface 602 of first reinforcing end assembly 614 is adhered to interior surface 602 of second reinforcing end assembly 616 to form end insert 1012. More specifically, interior surfaces 602 of reinforcing end panels 620 are adhered together, and/or interior surfaces 602 of pad panels 624 are adhered together. Each pair of stacking flaps 626 and 628 are rotated toward exterior surface 604 of first reinforcing end assembly 614. In the exemplary embodiment, stacking flaps 626 and 628 are not glued in place. Rather, end insert blank 600 is folded over and glued to itself.
A first end insert 1012 is inserted 1014 into cavity 714 adjacent first end panel assembly 110. More specifically, exterior surface 604 of first reinforcing end assembly 614 is positioned adjacent interior surface 102 of first end panel assembly 110 such that stacking flaps 626 and 628 are positioned between first reinforcing end assembly 614 and first end panel assembly 110. Insert 1012 and first end panel assembly 110 form first end wall 704. End insert 1012 can be adhered to first end panel assembly 110. However, such gluing can be omitted, and end insert 1012 can be removable from cavity 714 to transition container 700 into the knocked-down flat configuration. Similarly, a second end insert 1012 is inserted 1014 into cavity 714 adjacent second end panel assembly 114. More specifically, exterior surface 604 of first reinforcing end assembly 614 is positioned adjacent interior surface 102 of second end panel assembly 114 such that stacking flaps 626 and 628 are positioned between first reinforcing end assembly 614 and second end panel assembly 114. Insert 1012 and second end panel assembly 114 form second end wall 708. End insert 1012 can be adhered to second end panel assembly 114. However, such gluing can be omitted, and second end insert 1012 can be removable from cavity 714 to transition container 700 into the knocked-down flat configuration.
Inner end panels 160 and 204 are rotated toward cavity 714 to define 1016 windows 716 and 720 in end walls 704 and 708, respectively. More specifically, first inner end panel 160 is rotated about hinge line 164 toward cavity 714 through cutouts 622. Tab 176 is coupled within slot 246 to secure inner side panel 160 in position to form first end lip 732. An opening formed by rotating inner end panel 160 defines 1016 window 716 in first end wall 704. Similarly, second inner end panel 204 is rotated about hinge line 208 toward cavity 714 through cutouts 622. Tab 220 is coupled within slot 286 to secure inner side panel 204 in position to form second end lip 736. An opening formed by rotating inner end panel 204 defines 1016 window 720 in second end wall 708. Further, ledge 715 is formed at first end wall 704 and the ledge is formed at second end wall 708 by stacking flaps 626 and 628 forcing reinforcing end panels 620 and pad panels 624 into cavity 714, away from end panel assemblies 110 and 114.
Depending on the type of product 1006 to be contained within container 700, dividers 1018 can be positioned 1020 within cavity 714. Dividers 1018 can be positioned within cavity 714 before or after products 1006 are positioned 1022 within container 700. However, it should be understood that dividers 1018 are not required. Products 1006 are then positioned 1022 within container 700. Windows 716, 718, 720, and/or 722 enable viewing of products 1006 within container 700. A plurality of containers 700 can be stacked 1024 for shipping, storage, and/or display of products 1006. More specifically, an upper container 700 is nested in a lower container 700 such that upper container 700 is at least partially received within cavity 714 of lower container 700. More specifically, bottom wall 712 of the upper container is supported by first end wall ledge 715 and the second end wall ledge. Because ledges 715 orient at least reinforcing end panels 620 to be substantially perpendicular to bottom wall 712, a weight of the upper container is supported in a normal direction by at least reinforcing end panels 620, stacking flap 626, and/or stacking flap 628 at top edge 717.
To facilitate balancing a stack 1026 of containers 700, containers 700 can be alternately rotated by 180°. Indicia, such as “X”s and “O”s, on exterior surface 104 facilitates tracking which orientation a container 700 is in. Such alternate stacking is used because of the arc of blank 100. In an alternative embodiment, containers 700 are stacked 1024 at any suitable orientation. In the exemplary embodiment, stacks 1026 of containers 700 are positioned 1028 on a pallet 1030.
To ship pallet 1030 of stacked containers 700, a top filler 1032 can be constructed 1034 and positioned 1035 on a top of stacks 1026. If a display including pallet 1030 includes a header 1036, header 1036 is positioned 1038 on top filler 1032. Corner boards 1040 are positioned 1042 at corners of pallet 1030, and a top cap 1044 is positioned 1042 on top filler 1032 and/or header 1036. The pallet assembly is then wrapped in, for example, stretch wrap and/or bands. Notably, no additional shroud is required for shipping because containers 700 include pad panels.
FIG. 14 is a schematic view of an exemplary method 1100 for converting container 700 (shown in FIG. 8) from erect configuration 702 (shown in FIG. 8) to display configuration 748 (shown in FIG. 10). Method 1100 is performed manually to provide a larger opening for viewing and accessing products 1006 within container 700. When containers 700 are received on pallet 1030, top cap 1044, corner boards 1040, header 1036 (shown in FIG. 13B), and/or top filler 1032 (shown in FIG. 13B) are removed 1102 from stack 1026 of containers 700.
To transition container 700 from erect configuration 702 to display configuration 748, at least one pad panel assembly is removed from container 700. In the exemplary embodiment, pad panels 162, 182, 206, 226, 416, 520, and 624 are removed from walls 704, 706, 708, and 710 to form access openings 750, 752, 754, and 756 in a respective wall 704, 706, 708, or 710. In a particular embodiment, each assembly of pad panels is pulled 1104 outward, away from cavity 714, then rotated 1106 horizontally to remove pad panels. In the exemplary embodiment, pad panels 162 and 624 are removed from first end wall 704, pad panels 182 and 416 are removed from first side wall 706, pad panels 206 and 624 are removed from second end wall 708, and/or pad panels 226 and 520 are removed from second side wall 710. Stacked containers 700 in the display configuration can be used for a point-of-sale display, such as a display 1200 shown in FIG. 15.
The embodiments described herein provide a blank assembly that can be assembled and formed into a knocked-down flat container using at least one machine. More specifically, the container tapers outwardly towards the top thereof, but includes features that facilitate assembling the plurality of blanks into an assembled blank and constructing a knocked-down flat container. The taper of the container enables a first container to be nested in a second, lower container for shipping, storage, and/or display. The above-described container further includes an auto-forming bottom wall that automatically forms as the container is transitioned from a knocked-down flat configuration to an erect configuration. At least one bottom panel extends across a width of the container such that the bottom wall is a full-overlap auto-locking bottom wall. The knocked-down flat container can be shipped to a customer or another location, and can then be erected manually. As such, the receiver of the knocked-down flat container does not need a machine and/or adhesive to finalize formation of the container by erecting the container.
Further, the access opening in each wall of the container allows 360° viewing of and/or access to the products within the container. The pad panels that are removed to create the access openings facilitate reducing shipping material by eliminating the need for a shroud between the products and shrink wrap covering a stack of containers. Moreover, the ledge defined at least partially by the stacking flaps enables the container to support an upper container on the ledges to create a stack of containers. The ledge enables the weight of the upper container to be supported in a direction substantially parallel to gravity, rather than by using a force oriented orthogonally to gravity. As such, a lower container can support the weight of the upper container(s) substantially without buckling outwardly.
