The blank 101 has a longitudinal axis L1 and a lateral axis L2. The blank 101 includes a central panel 110 foldably connected to a first side panel 112 at a first longitudinal fold line 114. A second side panel 116 is foldably connected to the central panel 110 along a second longitudinal fold line 118. A first end panel 120 is foldably connected to the central panel 110 along a first lateral fold line 122 at one longitudinal end of the central panel 110, and a second end panel 124 is foldably connected to the central panel 110 along a second lateral fold line 126 at another longitudinal end of the central panel 110. As shown in
In the illustrated embodiment, the blank 101 includes end flaps 130, 132 foldably connected to the first end panel 120 along respective fold lines 134, 136 at respective ends of the first end panel 120. End flaps 138, 140 are respectively foldably connected to the second end panel 124 along the respective fold lines 142, 144 at respective ends of the second end panel 124. Each of the end flaps 130, 138, 132, 140 includes a locking feature, such as a projection 146 and a recess 148 for engaging a respective slit 150 in a respective side panel 112, 116. The end flaps could be otherwise shaped, arranged, positioned, and/or configured without departing from the disclosure. For example, the locking features could be omitted from the end flaps 130, 132, 138, 140, and/or the end flaps 130, 138, 132, 140 could be glued to the respective side panels 112, 116. In an alternative embodiment, the end flaps 130, 138, 132, 140 could be foldably connected to the respective side panels 112, 116, and the slits 150 could be disposed in the end panels 120, 124. Alternatively, the end flaps 130, 132, 138, 140 could be omitted from the blank 101 without departing from the disclosure.
As shown in
As shown in
In one embodiment, the blank 101 can be formed from a web of material. For example, areas of the material can be deformed upwardly with respect to the neutral area 160 to form the emboss features 154, and areas of the material can be deformed downwardly with respect to the neutral area 160 to form the deboss features 156. Any of the fold lines 114, 118, 122, 126, 134, 136, 142, 144, the cut lines 150, and/or the edges of the blank 101 could be formed before or after the bosses 152 in the web of material. The blank 101, including the bosses 152, could be otherwise formed without departing from the disclosure. Additionally, in alternative embodiments, the blank 101 could be otherwise shaped, arranged, and/or configured.
As shown in
In the illustrated embodiment, the stiffening features 128 can help prevent buckling, bending, and/or other failure of the central panel 110. For example, the bosses 152 can be arranged so that little or none of the edges 158 are aligned with the grain of the blank 101 (in one embodiment, the grain is parallel to the longitudinal direction L1). For example, each of the edges 158 can have a length (e.g., extending around the perimeter of the respective boss 152), and the edge 158 can be nonparallel with the grain of the blank 101 along at least a majority of the length of the edge 158. In another embodiment, the edge 158 is nonparallel with the grain along at least a portion of the length of the edge 158. If the central panel 110 starts to buckle or fold, a fold or crease can start to propagate across the central panel. For example, in one embodiment, a central panel with the stiffening features omitted could form a fold (e.g., buckle) at one corner, and the fold could propagate to extend to the opposing corner, which could cause the tray to collapse. However, for the central panel 110, a fold or crease can intersect with a boss 152 and be redirected along the edge 158 of the boss. The fold can propagate along at least a portion of the edge 158, and the fold can stop or continue to another boss 152, which can further redirect the fold. Accordingly, the bosses 152 can disrupt a fold or crease in the central panel 110 and can help prevent a fold or crease from extending across the central panel 110 to help prevent failure of the tray 103. In one embodiment, the stiffening features 128 can result in a ten percent increase in strength of the central panel 110. For example, a central panel with the stiffening features and comprising an 18 point paperboard might replace a panel without the stiffening features and comprising 20 point paperboard.
In the illustrated embodiment, the plurality of stiffening 128 features is formed in the central panel 110 of the tray 103. In alternative embodiments, however, the stiffening features can be formed in one or more panels of any suitable construct (e.g., fully enclosed carton, wrap, basket carrier, divider panel, etc.). The blank 101 and tray 103 are included by way of example only. Additionally, as shown in
Any of the features of the various embodiments of the disclosure can be combined with, replaced by, or otherwise configured with other features of other embodiments of the disclosure without departing from the scope of this disclosure. Further, it is noted that the stiffening features of the various embodiments can be incorporated into a tray, carrier, carton, or any other suitable construct having any suitable style or panel configuration. The trays described above are included by way of example. For example, the stiffening features could be included in one or more panels and/or flaps of a fully enclosed carton, a basket-style carrier, a wraparound carrier, a divider, etc. Additionally, the shapes of the stiffening features (i.e., the shapes of the edges defining the various bosses described above) can be substantially any shape. The shapes described above and included in the figures are included by way of example.
In general, the blank may be constructed from paperboard having a caliper so that it is heavier and more rigid than ordinary paper. The blank can also be constructed of other materials, such as cardboard, or any other material having properties suitable for enabling the carton to function at least generally as described above. The blank can be coated with, for example, a clay coating. The clay coating may then be printed over with product, advertising, and other information or images. The blank may then be coated with a varnish to protect information printed on the blanks. The blank may also be coated with, for example, a moisture barrier layer, on either or both sides of the blanks. The blank can also be laminated to or coated with one or more sheet-like materials at selected panels or panel sections.
In accordance with the exemplary embodiments, a fold line can be any substantially linear, although not necessarily straight, form of weakening that facilitates folding therealong. More specifically, but not for the purpose of narrowing the scope of the present disclosure, fold lines include: a score line, such as lines formed with a blunt scoring knife, or the like, which creates a crushed or depressed portion in the material along the desired line of weakness; a cut that extends partially into a material along the desired line of weakness, and/or a series of cuts that extend partially into and/or completely through the material along the desired line of weakness; and various combinations of these features. In situations where cutting is used to create a fold line, typically the cutting will not be overly extensive in a manner that might cause a reasonable user to incorrectly consider the fold line to be a tear line.
The above embodiments may be described as having one or more panels adhered together by glue during erection of the carton embodiments. The term “glue” is intended to encompass all manner of adhesives commonly used to secure carton panels in place.
The foregoing description of the disclosure illustrates and describes various exemplary embodiments. Various additions, modifications, changes, etc., could be made to the exemplary embodiments without departing from the spirit and scope of the disclosure. It is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. Additionally, the disclosure shows and describes only selected embodiments of the disclosure, but the disclosure is capable of use in various other combinations, modifications, and environments and is capable of changes or modifications within the scope of the inventive concept as expressed herein, commensurate with the above teachings, and/or within the skill or knowledge of the relevant art. Furthermore, certain features and characteristics of each embodiment may be selectively interchanged and applied to other illustrated and non-illustrated embodiments of the disclosure.
This application claims the benefit of U.S. Provisional Patent Application No. 61/963,866, filed Dec. 16, 2013.
