The embodiments described herein relate generally to a tray formed from a blank of sheet material and, more particularly, to a tray for supporting a plurality of containers included within the tray.
At least some known trays are configured to hold a plurality of containers therein. Most of these known trays are formed from a relatively large blank having a plurality of panels that fold and/or wrap to define container holders. More specifically, the plurality of panels form a rectangular tube having cutouts into which the containers are inserted. Because these trays are formed from a relatively large blank of sheet material they can be expensive to make. Moreover, because of the plurality of panels, they can be complicated to form.
Another known tray includes single-thickness side and end walls having a cup holder that extends outwardly from each end wall. The end walls of such a tray include side flaps that couple to an adjacent side wall. The end walls and side flaps are taller than the side walls. As such, when a cup is positioned in the tray, the cup is secured by the combination of the cup holder, the end wall, and the side flap. Notably, the retractable cup holders only extend from the end walls because the end wall and side flap cooperate with the cup holder to secure the cup in the tray. Further, the central portion of the tray is configured to allow for other food items to be positioned therein. As such, this other known tray is limited in the number of containers it is able to support therein.
In one aspect, a blank for forming a tray is provided. The blank includes a bottom panel, a pair of opposing end panels connected to the bottom panel, and a pair of opposing side panels connected to the bottom panel. A first divider panel assembly is defined within the bottom panel and a first end panel of the pair of end panels. The first divider panel assembly includes a first upper panel and a first inner panel connected at a first fold line. The first upper panel is defined within the first end panel and the first inner panel is defined within the bottom panel. In an erect configuration, the first upper panel is configured to be at a first angle to the bottom panel, and the first inner panel is configured to be a second angle to the first end panel. A second divider panel assembly is defined within the bottom panel and a first side panel of the pair of side panels. The second divider panel assembly includes a second upper panel and a second inner panel connected at a second fold line. The second upper panel is defined within the first side panel, and the second inner panel is defined within the bottom panel. In the erect configuration, the second upper panel is configured to be at a third angle to the bottom panel, and the second inner panel is configured to be at a fourth angle to the first side panel.
In another aspect, a tray formed from a blank of sheet material is provided. The tray includes a bottom wall, a pair of opposing end walls connected to the bottom wall, and a pair of opposing side walls connected to the bottom walls. A first divider structure extends from the bottom wall and a first end wall of the pair of end walls. The first divider structure includes a first upper panel and a first inner panel connected at a first fold line. The first upper panel is at a first angle to the bottom wall, and the first inner panel is at a second angle to the first end wall. A second divider structure extends from the bottom wall and a first side wall of the pair of side walls. The second divider structure includes a second upper panel and a second inner panel connected at a second fold line. The second upper panel is at a third angle to the bottom wall, and the second inner panel is at a fourth angle to the first side wall.
In yet another aspect, a method for forming a tray from a blank of sheet material is provided. The blank of sheet material includes a bottom panel, a pair of opposing end panels connected to the bottom panel, a pair of opposing side panels connected to the bottom panel, a first divider panel assembly defined within the bottom panel and a first side panel of the pair of side panels, and a second divider panel assembly defined within the bottom panel and a first end panel of the pair of end panels. The first divider panel assembly includes a first upper panel defined within the first side panel and a first inner panel defined within the bottom panel. The second divider panel assembly includes a second upper panel defined within the first end panel and a second inner panel defined within the bottom panel. The method includes rotating the pair of side panels toward the bottom panel to form a pair of opposing side walls, rotating the first upper panel with respect to the first side panel and the first inner panel with respect to the bottom panel to form a first divider structure, rotating the pair of end panels toward the bottom panel to form a pair of opposing end walls, and rotating the second upper panel with respect to the first end panel and the second inner panel with respect to the bottom panel to form a second divider structure.
In still another aspect, a blank for forming a tray is provided. The blank includes a bottom panel, a pair of opposing end panels connected to the bottom panel, a pair of opposing side panels connected to the bottom panel, and a plurality of divider panel assemblies defined within the bottom panel and a first side panel of the pair of side panels. Each divider panel assembly of the plurality of divider panel assemblies includes an upper panel and an inner panel connected at a fold line. The upper panel is defined within the first side panel, and the inner panel is defined within the bottom panel. The upper panel is configured to be at a first angle to the bottom panel, and the inner panel is configured to be at a second angle to the first side panel in an erected configuration.

First side panel 32 has a free edge 40 that defines a top edge of first side panel 32 when tray 100 is formed, and second side panel 36 has a free edge 42 that defines a top edge of second side panel 36 when tray 100 is formed. A first end flap 44 extends from an end edge of first side panel 32 at a fold line 46, and a second end flap 48 extends from an opposing end edge of first side panel 32 at a fold line 50. Each end flap 44 and 48 includes free edges 52, 54, and 56. Similarly, a third end flap 58 extends from an end edge of second side panel 36 at a fold line 60, and a fourth end flap 62 extends from an opposing end edge of second side panel 36 at a fold line 64. Each end flap 58 and 62 includes free edges 52, 54, and 56. In the exemplary embodiment, each end flap 44, 48, 58, and 62 is separated from an adjacent end panel 20 or 24 by a gap 66; however, it should be understood that any of end flaps 44, 48, 58, and/or 62 can be separated from an adjacent end panel 20 or 24 by a cut line without gap 66.
Each end panel 20 and 24 has a height H1, and each side panel 32 and 36 has a height H2. In the exemplary embodiment, height H1 is substantially equal to height H2. Alternatively, height H1 is other than substantially equal to height H2, for example less than or greater than height H2. In the exemplary embodiment, end flaps 44, 48, 58, and 62 each have a height H3 that is approximately equal to, or slight smaller than height H1. Further, end panels 20 and 24 each have a width W1, and side panels 32 and 36 each have a width W2 that is larger than width W1. Alternatively, width W2 is equal to or less than width W1 depending on what type and/or how many products tray 100 supports therein.
Blank 10 further includes a plurality of divider panel assemblies 68. In the exemplary embodiment, blank 10 includes a first divider panel assembly 68a defined within at least one end panel 20 and/or 24 and a second divider panel assembly 68b defined within at least one side panel 32 and/or 36. Each divider panel assembly 68a and 68b is configured similarly and is referred to generically as divider panel assembly 68 for the sake of simplicity. In the exemplary embodiment, each end panel 20 and 24 includes one divider panel assembly 68, and each side panel 32 and 36 includes a plurality of divider panel assemblies 68. Alternatively, each side panel 32 and 36 includes one divider panel assembly 68 such that tray 100 is configured to support four containers. In the exemplary embodiment, divider panel assemblies 68 have any suitable size and/or configuration based on the containers supported by tray 100. Further, divider panel assemblies 68 are configured to cooperate with an adjacent divider panel assembly 68 to secure the containers within tray 100. For example, each of the containers is contacted by two divider panel assemblies 68.
In the exemplary embodiment, each divider panel assembly 68 includes an upper panel 70 defined within a panel 20, 24, 32, and/or 36 and an inner panel 72 defined within bottom panel 22. More specifically, upper panel 70 is defined within a panel 20, 24, 32, and/or 36 by side cut lines 74 and a fold line 76. Inner panel 72 is defined within bottom panel 22 by side cut lines 78 and a fold line 80. Side cut lines 78 are continuous with side cut lines 74 across a respective fold line 26, 28, 34, and/or 38. Upper panel 70 and inner panel 72 are connected to each other at a fold line 82 that is substantially collinear with a respective fold line 26, 28, 34, or 38. Alternatively, fold line 82 is offset from a respective fold line 26, 28, 34, or 38. In the exemplary embodiment, a depth D1 of upper panel 70 is substantially equal to a height H4 of inner panel 72 such that upper panel 70 is substantially perpendicular to inner panel 72 when a divider structure 212 (shown in
Upper side cut lines 74 include at least a curved portion 84 to correspond to a shape of the products supported by tray 100. In the exemplary embodiment, upper side cut lines 74 include curved portion 84 and a substantially straight portion 86. More specifically, curved portion 84 has an edge configured to interface with or engage a container supported within tray 100. As such, curved portion 84 of upper side cut lines 74 defines an engagement edge of divider panel assembly 68. Engagement edges of adjacent divider panel assemblies 68 are configured to cooperate with each other to secure a container within in tray 100, as described in more detail below. In the exemplary embodiment, first divider panel assembly 68a includes a first engagement edge defined by curved portion 84 and second divider panel assembly 68b includes a second engagement edge defined by curved portion 84 adjacent to the first engagement edge. The first engagement edge and the second engagement edge are configured to cooperate with each other to secure a product between first divider panel assembly 68a and second divider panel assembly 68b in the erected configuration. Further, substantially straight portion 86 is configured to space the products from a wall of tray 100. Upper side cut lines 74 define free side edges of upper panel 70 when tray 100 is formed as described below. Inner side cut lines 78 are substantially straight and define free side edges of inner panel 72 when tray 100 is formed. Inner panel 72 has a width between side cut lines 78 based on a size of the containers supported by tray 100.
When blank 10 is in a flat, unformed state, divider panel assemblies 68 are in a flat configuration. More specifically, upper panel 70 is coplanar with a respective panel 20, 24, 32, or 36 and inner panel 72 is coplanar with bottom panel 22 in the flat configuration.
Referring to
When side panels 32 and 36 are substantially perpendicular to bottom panel 22, upper panels 70 are at an angle, such as a right angle, to a respective side wall 104 or 106 and inner panels 72 are at an angle, such as a right angle, to bottom wall 108. In the exemplary embodiment shown in
End flaps 44, 48, 58, and 62 are rotated about fold lines 46, 50, 60, and 64 to be substantially perpendicular to a respective side panel 32 or 36. In the exemplary embodiment as shown in
End panels 20 and 24 are rotated about fold lines 26 and 28 toward bottom panel 22 to be substantially perpendicular to bottom wall 108. Exterior surface 14 of end flaps 44, 48, 58, and 62 are coupled to interior surface 12 of an adjacent end panel 20 and/or 24 to form a first end wall 114 and a second end wall 116. More specifically, first end wall 114 includes first end panel 20, first end flap 44, and third end flap 58. Similarly, second end wall 116 includes second end panel 24, second end flap 48, and fourth end flap 62. In the exemplary embodiment, end walls 114 and 116 and side walls 104 and 106 have substantially the same height.
As end panels 20 and 24 are rotated, divider panel assemblies 68 associated with end panels 20 and 24 begin to buckle inwardly at fold lines 76, 80, and 82, as shown in
In the exemplary embodiment, an upper surface 118 of each divider structure 112 is below a top edge 120 of walls 104, 106, 114, and 116. Further, each upper panel 70 is at angle to a respective wall 104, 106, 114, or 116, and each inner panel 72 is at an angle to bottom wall 108. In the exemplary embodiment, the angles are substantially right angles; however, the angles can be any suitable angle that is other than 0° or 180°.
Products 102 are positioned within a cavity 122 of tray 100 between at least two divider structures 112 as shown in
At least on divider structure 112 can be collapsed to provide tray 100 having at least one less opening 110. More specifically, a force is applied to interior surface 12 around fold line 82 to rotate upper panel 70 about fold line 76 and inner panel 72 about fold line 80 until upper panel 70 is substantially coplanar with a respective panel 20, 24, 32, or 36 and inner panel 72 is substantially coplanar with bottom panel 22. Such a configuration is referred to as a collapsed configuration, and may be used to store or transport trays 100. In the collapsed configuration, inner panel 72 forms a portion of bottom wall 108, and upper panel 70 forms a portion of an associated wall 104, 106, 114, or 116. Divider structures 112 can be re-formed to the erected configuration by applying a force to exterior surface 14 around fold line 82 to rotate upper panel 70 about fold line 76 and inner panel 72 about fold line 80 until upper panel 70 is substantially perpendicular to a respective wall 104, 106, 114, or 116 and inner panel 72 is substantially perpendicular to bottom wall 108.
Side cut lines 204 are curved because an inner panel 206 of each divider panel assembly 202 has a height H5 that is longer than depth D1 of upper panel 70. As such, inner panel 206 will be at acute angles to bottom panel 22 and upper panel 70 when a tray 250 (shown in
Divider structures 252 are beneficial to contact more of product 102 as compared to divider structures 112 and isolate a center round tub product 102a in all directions in a horizontal plane.
In the exemplary embodiment, divider panel assembly 302 includes an upper panel 304 defined within side panel 32 or 36 and an inner panel 306 defined within bottom panel 22. More specifically, upper panel 304 is defined within panel 32 or 36 by side cut lines 308 and a fold line 310. Cut lines 312 separate upper panel 304 from bottom panel 22. In the exemplary embodiment, cut lines 312 are substantially collinear with a respective fold line 34 or 38; however, it should be understood that at least one cut line 312 can be offset from a respective fold line 34 or 38. Side cut lines 308 are substantially straight and configured to space products from a wall 104 and/or 106 (shown in
In the exemplary embodiment, slots 314 are defined within upper panel 304 by cut lines 316 and cut lines 312. More specifically, slots 314 extend inwardly a distance from cut line 312 toward fold line 310. Slots 314 are substantially rectangular in the exemplary embodiment; however slots 314 can have any suitable configuration depending on a configuration of a product supported within the tray. In a particular embodiment, slots 314 are configured to contact a side edge of a product 352 supported in tray 350 to secure product 352 within tray 350. In the exemplary embodiment, slots 314 are equally spaced apart along side panel 32 or 36 regardless of whether slots 314 are on same divider panel assembly 302 or on adjacent divider panel assemblies 302. Alternatively, at least two adjacent slots 314 have a spacing different than the spacing between another two adjacent slots 314. In the exemplary embodiment, each slot 314 defines an engagement edge of divider panel assembly 302 that is configured to engage a product positioned within tray 350 formed from blank 300.
Inner panel 306 is defined within bottom panel 22 by side cut lines 318 and a fold line 320. Side cut lines 318 are continuous with an adjacent slot cut line 316 across a respective fold line 34 or 38. Upper panel 304 and inner panel 306 are connected to each other at a fold line 322 that is substantially collinear with cut lines 312 and/or fold line 34 or 38. Alternatively, fold line 322 is offset from cut lines 312 and/or fold line 34 or 38. In the exemplary embodiment, inner side cut lines 318 are substantially straight and define free side edges of inner panel 306 when the tray is formed. Inner panel 306 has a width between side cut lines 318 based on a size of the products supported by tray 350.
The above-described embodiments provide a tray for supporting a plurality of containers and/or products using less material than is used in known tube-type trays. More specifically, the divider panel assemblies defined within the side, end, and bottom panels do not require a plurality of panels to form a tube. Further, because each container is contacted by two divider structures configured to correspond to the shape of the container, the container is more securely supported within the tray, as compared to trays using the side and end walls in conjunction with one holder to secure a container.
Exemplary embodiments of a tray for supporting containers and a blank for making the same are described above in detail. The methods, blanks, and trays are not limited to the specific embodiments described herein, but rather, components of blanks and/or trays and/or steps of the methods may be utilized independently and separately from other components and/or steps described herein.
