FIG. 8A shows a bottom view of a carton formed from the blank ofFIG. 7.FIG. 8B shows a top view of the carton ofFIG. 8A. The blank405 may be folded from the configuration shown inFIG. 7 to the configurations shown inFIGS. 8A and 8B by folding the blank405 alongfold lines409,411,421,431,441,451, and461. During a folding sequence, the end flaps are folded toward the interior, with either the end flaps at thefirst end404 or the end flaps at thesecond end406 folded inward first. Atend404, end flaps412,416,422,432,436,442,446,452,462,466 are folded inwardly alongfold lines413,417,423,433,437,443,447,453,463,467, respectively, so as to extend substantially perpendicular topanel420. Next, end flaps422 and454 are folded inwardly alongrespective fold lines423 and453 so as to extend substantially perpendicular topanel420. Atend406, end flaps414,418,424,434,438,444,448,454,464,468 are folded inwardly alongfold lines415,419,425,435,439,445,449,454,465,469, respectively, so as to extend substantially perpendicular topanel420. Next, end flaps424 and454 are folded inwardly alongrespective fold lines425 and455 so as to extend substantially perpendicular topanel420. Generally, end flaps412,416,422,432,436,442,446,452,462, and466 are adhered, such as by an adhesive such as glue, to form afirst end1404 ofcarton1400, and endflaps414,418,424,434,438,444,448,454,464, and468 are adhered, such as by an adhesive such as glue, to form asecond end1406 ofcarton1400.
Panels407 and470 are folded inwardly to form a ledge or lip over each compartment that extends inwardly along and around an upper portion of thecarton1400 as shown inFIG. 8B.
The flaps and panels detailed herein generally are secured to form a package, or carton. It is understood that forming the carton, packing the carton, and/or loading the carton and methods that differ than the forming, packing, and/or loading configurations discussed herein are within the scope of the disclosure.
In general, the blank may be constructed from paperboard having a caliper of at least about 13, for example, 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 blanks may then be coated with a varnish to protect information printed on the blanks. The blanks may also be coated with, for example, a moisture barrier layer, on either or both sides of the blanks. The blanks can also be laminated to or coated with one or more sheet-like materials at selected panels or panel sections.
The above embodiments may be described as having one or panels adhered together by glue. The term “glue” is intended to encompass all manner of adhesives commonly used to secure paperboard or carton panels in place, and the adhesive material can be replaced by, or supplemented with any suitable fastening devices.
The term “line” as used herein includes not only straight lines, but also other types of lines such as curved, curvilinear or angularly displaced lines. 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.
As an example, a tear line can include: a slit that extends partially into the material along the desired line of weakness, and/or a series of spaced apart slits that extend partially into and/or completely through the material along the desired line of weakness, or various combinations of these features. As a more specific example, one type tear line is in the form of a series of spaced apart slits that extend completely through the material, with adjacent slits being spaced apart slightly so that a nick (e.g., a small somewhat bridging-like piece of the material) is defined between the adjacent slits for typically temporarily connecting the material across the tear line. The nicks are broken during tearing along the tear line. The nicks typically are a relatively small percentage of the tear line, and alternatively the nicks can be omitted from or torn in a tear line such that the tear line is a continuous cut line. That is, it is within the scope of the present disclosure for each of the tear lines to be replaced with a continuous slit, cut line, or the like. For example, a cut line can be a continuous slit or could be wider than a slit without departing from the present disclosure.
Any dimensions shown in the figures are exemplary only and can be expanded or contracted, such as to accommodate items of different sizes, configurations, or dimensions. These dimensions should not be construed as limiting in any manner.
The foregoing description of the disclosure illustrates and describes various embodiments.
