As shown in FIGS. 2-8, and described in the following in accordance with one acceptable example, the carton 5 is formed from the blank 3 through application of glue or adhesive onto areas 141 of the intermediate panels 110, 117, 123 (FIG. 2). Thereafter, the intermediate panels 97, 99, 101 may be folded about fold lines 71A, 71B, 71C, 71D, and 113 in the direction of arrow A1 (FIG. 3) such that the intermediate panels 97, 99, 101 are brought into substantially face-to-face contact with the intermediate panels 110, 117, 123, respectively. This folding sequence may be similar to a z-folding sequence where the corner flap 119 and the associated adhesive region 141 are brought into contact with an exterior surface of the first side panel 25; the second side intermediate panel 117 and the associated adhesive region 141 are brought into contact with an interior surface of the first side intermediate panel 99; the second front intermediate panel 110 and the associated adhesive regions 141 are brought into contact with an interior surface of first front intermediate panel 97; the fourth side intermediate panel 123 and the associated adhesive region 141 are brought into contact with third side intermediate panel 101; and, the corner flap 125 and the associated adhesive region 141 are brought into contact with an exterior surface of the second side panel 31. As shown in FIG. 4, the z-folding sequence brings the longitudinal fold line 115 into substantial registration with the longitudinal fold line 71. As shown in FIG. 5, the tear lines 71A, 71B, and 71D, and the fold line 71C are further in registration with the fold lines 71 and 115 after the z-fold sequence.
Thereafter, the panels 23, 25, 31, and 37 may be folded to at least partially form an interior 11 of the carton 5, for example, by creation of a sleeve (FIGS. 6-7). The attachment flap 41 may receive adhesive or glue and may be affixed to an interior surface of the back panel 37 (FIG. 6). Upon formation of the sleeve, the ends 68, 69 of the carton 5 may be closed by inwardly folding and attaching the end flaps 49, 55, 61, 65 and 51, 57, 63, 67, respectively. The end flaps 49, 55, 61, 65 and 51, 57, 63, 67 may be attached with glue in some embodiments. The carton may be filled with products to be held therein during any suitable portion of carton formation, for example, through inclusion of a filled liner containing a food product. The filled liner may be adhered or affixed to an interior surface 9 of the carton 5 in some embodiments.
As shown in FIG. 10, the lid 150 is formed from lid features 91 during folding of the panels 23, 25, 31, and 37. The lid 150 includes the end flaps 49, 55, 61, and the intermediate panels 97, 99, 101, 110, 117, 123. The fold lines 113, 114, 116 form a bottom edge of the lid 150. The alignment of the fold lines 115, 120, 122 with the fold lines 71, 71C and tear lines 71A, 71B, 71D allows the closing of the carton 5 in conventional seal-end processing equipment that is configured to seal conventional cartons without the above-noted z-fold arrangements of the intermediate panels 97, 99, 101, 110, 117, 123. The lid 150, lid features 91, and associated features may be alternatively shaped, arranged, and/or configured without departing from the scope of this disclosure.
As shown in FIG. 10, the closed end 68 of the carton 5 may be initially opened by activating the lid 150 by separating it from at least a portion of the carton 5 and pivoting the lid 150 about the hinge or fold line 71 to an open position. The lid 150 can be pivoted to the open position by sliding an object (e.g., a finger) beneath edge 113 to detach tear lines 71A, 71B, 71D and arcuate tear lines 121, 127. As shown, the tearing and detaching causes locking tab 93 to remain foldably attached to front panel 23 while lid 150 is formed and hinged upon fold line 71. Thereafter, as shown in FIG. 11, the interior 11 of the carton 5 may be accessed.
To close or reclose the end 68 of the carton 5, the lid 150 may be hinged down about the hinge or fold line 71 into a closed position such that locking tab 93 engages with recess 93A created during opening of the carton 5 (FIG. 11). Thereafter, the carton 5 may be reopened by simply lifting the lid 150, which de-engages the locking tab 93 from recess 93A.
Alternative assembling, loading, closing, opening, reclosing, and/or reopening steps may be used without departing from the scope of the disclosure. For example, the sleeve can be loaded and closed in an automated process, and the ends 68, 69 can be partially closed. Additionally, the carton 5 could be otherwise shaped, arranged, and/or configured without departing from the disclosure. The carton 5 could include various handle features for carrying the carton and could include various dispenser features for opening the carton in manners not herein described. Further the carton 5 could include other panel/flap closing configurations without departing from the disclosure.

The blanks may also be coated with, for example, a moisture barrier layer, on either or both sides of the blank. In accordance with the above-described embodiments, the blanks may be constructed of paperboard of a caliper such that it is heavier and more rigid than ordinary paper. The blanks can also be constructed of other materials, such as cardboard, hard paper, kraft lined paperboard, double kraft lined paperboard, or any other material having properties suitable for enabling the carton to function at least generally as described herein. The blanks can also be laminated or coated with one or more sheet-like materials at selected panels or panel sections.
In accordance with the above-described embodiments of the present disclosure, 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 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.
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 foam 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, 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.
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.
