DETAILED DESCRIPTION

Reference will now be made to the drawings wherein like reference numerals identify similar structural features or aspects of the subject disclosure. For purposes of explanation and illustration, and not limitation, an illustrative view of an embodiment of a tray in accordance with the disclosure is shown in FIG. 1A and is designated generally by reference character 100.
Other embodiments and/or aspects of this disclosure are shown in FIGS. 1B-7 . Certain embodiments described herein can be used to enable automated stacking of trays whether misaligned or otherwise.
In accordance with at least one aspect of this disclosure, referring to FIGS. 1A-2B, a tray 100 can include a plurality of first medialization features 101 located at a top portion (e.g., extending from a topmost surface and/or edge) of the tray 100, and a plurality of second medialization features 103 disposed at a bottom portion (e.g., extending from a bottom panel) of the tray 100. The first medialization features 101 can be configured to interact with the second medialization features 103 of an adjacent stacked tray 100 to cause medialization of the adjacent stacked tray 100. Medialization (e.g., centering to a midline) can cause tray alignment (e.g., of central axes of multiple trays 100) and automated stacking of trays 100. For example, the medialization features 101, 103 can be configured to cause a center axis of a top tray to have a motion vector pointing at the center axis of a bottom tray such that the center axes converge as the adjacent trays are vertically stacked.
In certain embodiments, the plurality of first medialization features 101 can be or include post tabs 105 extending upwardly from and/or beyond an uppermost portion of the tray 100. In certain embodiments, the plurality of second medialization features 103 can be or include one or more folding tabs 107 defined in a bottom of the tray 100.
The folding tabs 107 can be configured to be pushed upwardly by the post tabs 105 (e.g., as shown in FIG. 1C). The folding tabs 107 and the post tabs 105 can be configured to interact to cause medialization of adjacent stacked trays 100 during stacking. For example, with three or more folding tabs 107 (e.g., four as shown, one in each corner of tray 100) the forces generated by the post tabs 105 pushing up the folding tabs 107 (e.g., due to the material resistance in folding and/or the weight of the folding tabs 107), successive trays 100 will tend to medialize to center each tray 100 when stacked on an adjacent tray 100.
Each folding tab 107 can be connected to the base panel 109 at a tab fold line 111. In certain embodiments, the tab fold line 111 is positioned such that the folding tabs 107 fold inwardly while folding upwardly (e.g., as shown in FIG. 1C). The tab fold lines 111 can be any suitable fold line (e.g., a single crease) and can be sized (e.g., along with a thickness of the material forming the tray 100) to provide a predetermined resistance in folding. In certain embodiments, the tab fold line 111 can be straight. In certain embodiments, the tab fold line 111 can be curved (e.g., convex and/or concave). In certain embodiments, the tab fold line 111 can extend across or can be only a portion across the base panel. The tab fold line 111 can be formed on an upward facing surface of the base panel 109 such that the indentation is downward. Any suitable crease type or other suitable fold line type is contemplated herein.
The tray 100 can include a plurality of vertical posts 113. Each vertical post 113 can include a respective post tab 105 extending upwardly therefrom. In certain embodiments, each vertical post 113 can include an inner wall 115 and an outer wall 117 and each vertical post 113 can define a cavity 119 between the inner wall 115 and outer wall 117 such that a tray area 121 of the tray 100 is separated from the cavity 119 by the inner wall 115 of each vertical post 113.
In certain embodiments, each folding tab 107 is within a respective cavity 119 (e.g., within a planform projection, e.g., as shown in FIG. 1B) of each vertical post 113. In certain embodiments each post tab 105 can be formed from each outer wall 117 of each vertical post 113.
As shown in FIGS. 1A-1C, each vertical post 113 can be located at a corner of the tray 100, for example. Each post tab 105 can also include a corner shape (e.g., bent with the corner as shown). In certain embodiments, each post tab 105 can also include a ramp shape (e.g., as shown in FIG. 1C). In certain embodiments, each vertical post 113 can include a tab aperture 123 defined at a bottom thereof to receive the post tab 105 to allow the post tab 105 to nest within the tab aperture 123 and/or to move outwardly and inwardly relative to the tab aperture 123 (e.g., during medialization).
The tray 100 can be made of paper material or plastic in certain embodiments (e.g., cardboard as shown). Any suitable material is contemplated herein.
In accordance with at least one aspect of this disclosure, referring to FIGS. 2A and 2B, a blank 200 can be configured to form a tray as disclosed herein, e.g., a tray 100 as described above. For example, in accordance with at least one aspect of this disclosure, an embodiment of a blank 200 for a tray 100 can include a base panel 109 configured to form a bottom of the tray 100. The blank 200 can include a plurality of folding tabs 107 foldably connected to the base panel 109 at one or more tab fold lines 111.
The blank 200 can also include a plurality of side panel assemblies 225 (e.g., two on opposite sides of the base panel 109 as shown) foldably connected to the base panel 109 at side panel assembly fold line 226. Each side panel assembly 225 can include a plurality of side panels 227 a, b, c, d foldably connected together and configured to form the plurality of vertical posts 113 of the tray 100, for example.
The blank 200 can include a plurality of post tabs 105. Each post tab 105 can extend away from each side panel assembly 225 away from the base panel 109. The post tabs 105 can be configured to interact with the folding tabs 107 of an adjacent stacked tray 100 when formed to cause medialization of the adjacent stacked tray 100 (e.g., as shown in FIG. 1C with trays 100A and 100B).
In certain embodiments, e.g., as shown, each tab fold line 111 can be positioned at a corner of the base panel 109, for example. Any other suitable locations for each fold line 111 and each folding tab 107 (e.g., to be coincident in stacking with post tabs 105) are contemplated herein.
In certain embodiments, the plurality of side panels 227 a, b, c, d of each side panel assembly 225 can include a base side panel 227 a foldably connected to the base panel 109 at the side panel assembly fold line 226. The base side panel 227 a can include a side wall portion 229 and two leg portions 231. Each side panel assembly 225 can also include a first vertical panel 227 b foldably connected to each leg portion 231 at a first vertical fold line 233, a second vertical panel 227 c foldably connected the each first vertical panel 227 b via a second vertical fold line 235, and a third vertical panel 227 d foldably connected the each second vertical panel 227 b via a third vertical fold line 237. In certain embodiments, the third vertical panel 227 d can include an adhesive 239 (e.g., glue or tape strips as shown or in any other suitable shape or type). The first, second, and third vertical panels 227 b, c, d can be dimensioned to allow each third vertical panel 227 d to be folded onto an inner face of each respectively associated leg portion 231 of each base side panel 227 a to adhere to each respective leg portion 231 to form each vertical post 113 (e.g., as shown formed in FIGS. 1A and 1B).
In certain embodiments, each post tab 105 can extend from each leg portion 231 and each first vertical panel 227 b (e.g., as shown in FIG. 2A). For example, the first fold line 233 can be defined on each post tab 105 (e.g., forming a corner shape). For example, as shown in FIG. 2A, the first fold line 233 can be continuous between the leg portions 231 and each associated first vertical panel 227 b over the post tabs 105. Any other suitable location for the post tabs 105 is contemplated herein (e.g., relative with the folding tabs 107 to allow interaction when trays made from the same blanks are stacked). Any suitable location for the each post tab 105 and each folding tab 107 to interact and create a medialization force is contemplated herein.
A tab aperture 123 for each post tab 105 can be defined on opposite sides of each side panel assembly 225 having the same shape as the respective post tab 105 (e.g., as shown in FIG. 2A). Each tab aperture 123 can be formed for example by the same panels that form each post tab 105 (e.g., as a cut line negative of the post tab). Each post tab 105 can include any suitable shape, and can be different or the same as one or more other post tabs 105. Each tab aperture 123 can include a same or different shape as a respective post tab 105.
In certain embodiments, each post tab 105 includes a ramp shape (e.g., a trapezoidal, triangular, or other similar shape having ramped edges as shown in FIG. 2A). Any suitable shape that allows medialization with or without a ramp is contemplated herein.
In certain embodiments, the blank 200 can include a plurality of side support panels 241 each foldably connected to the base panel 109 at a respective side support fold line 243 perpendicular to each side panel assembly fold line 226. The blank 200 can include any other suitable panels, e.g., foldover support panels 245, 247, 249 configured to fold over to provide strength support, or for any other suitable purpose. As shown, adhesive 239 can be placed on any suitable panel (e.g., at for adhering foldover panels to side panels, for example) for any suitable purpose, e.g., as shown.
FIGS. 3A-3J illustrate an animation showing a misaligned (top) tray 100A interacting with another bottom tray 100B to cause medialization of the top tray 100A and alignment with the bottom tray 100B.
FIGS. 4A-4C illustrate another embodiment of a tray 400 in accordance with this disclosure. FIG. 5 illustrates another embodiment of a blank 500, e.g., for the embodiment of a tray 400. The tray 400 and the blank 500 can be similar to the tray 100 and blank 200, respectively, with different shaped folding tabs 405 (e.g., having a rounded and/or smaller shape).
FIGS. 6A-6C illustrate another embodiment of a tray 600 in accordance with this disclosure. FIG. 7 illustrates another embodiment of a blank 700, e.g., for the embodiment of a tray 600. The tray 600 and the blank 700 can be similar to the trays 100, 400 and blanks 200, 500, respectively, however, tray 600 and blank 700 can have the post tabs 605 and the folding tabs 607 at a different location.
For example, in certain embodiments, each post tab 605 can extend from each second vertical panel 227 c (e.g., and a respective tab aperture can also be defined in the second vertical panel 227 c). The base panel 609 can define the folding tabs 607 therein instead of having the folding tabs 607 extend from the defined edges of base panel 607. There can also be a gap 651 defined in the base panel 609 between the folding tab 607 and a corner of the base panel 609.
While embodiments have been shown having a four sided base panel, any suitable number of sides and corners is contemplated herein. Thus, any suitable number of vertical posts (e.g., three or more) having any suitable number of first medialization features is contemplated herein. Any suitable number and/or location of suitable second medialization features are also contemplated herein. Any suitable shape base panel is contemplated herein. Any suitable features other than post tabs and folding tabs to cause medialization are also contemplated herein. Moreover, embodiments can be applied to any suitable container type and are not limited to trays.
