Fold lines 46 and 39 together comprise fold line 23. End flap 44 is foldably connected along a fold line 44 at the second end 6 of panel 40.
As shown in FIG. 1, fold lines 13, 15, 19, 23, 25, 26, 33, 35, 39, 43, 45, 46 generally extend transverse to fold lines 9, 11, 21, and 31. One or more of fold lines 13, 19, 23, 26, 33, 39, 43, 46, also could be replaced by a single fold line such as indicated at 53, while one or more of fold lines 15, 25, 35, 45 could be replaced by a single fold line, such as indicated at 55. End flaps 12, 14, 22, 24, 28, 29, 32, 34, 42, 44, 48, 49 generally extend in a direction away from respective fold lines 13, 15, 19, 23, 25, 26, 33, 35, 39, 43, 45, 46 toward the periphery 8 of the blank 5. Further, the “panels,” which define the surfaces of sleeve 80 (FIG. 2) and/or carton 90 (FIG. 5) and form the blank 5, also can be referred to as “walls” or “sides.” Further still, the panels 10, 20, 30, 40 can be referred to as the surface they form when constructing the form of a carton, such as the sleeve shown in FIG. 2 or the carton shown in FIG. 5. For example, panel 10 can be referred to as the back panel, panel 20 can be referred to as first side panel, panel 30 can be referred to as front panel, and panel 40 can be referred to as second side panel. Additionally, end flaps 12, 22, 28, 29, 32, 42, 48, 49 can be closed to form a first end, such as a top end, and end flaps 14, 24, 34, 44 can be closed to form a second end, such as a bottom end, as shown in FIG. 4.
FIG. 2 illustrates the holding of the panels into a sleeve 80 formed from the blank 5 panels of FIG. 1. The blank 5 may be folded along fold lines 9, 11, and 31, and an adhesive, such as glue, can be applied to adhesive panel 7 (such as along an outer surface 3) to secure the panels of the blank 5 into a sleeve configuration, such as shown at 80 in FIG. 2. Generally, the adhesive flap 7 is adhered to an inner surface of panel 40. Alternatively, adhesive can be applied to an interior surface of panel 40 against which the adhesive flap 7 then is received.
FIG. 3 shows the sleeve 80 of FIG. 2 as it progresses from a flat configuration with selected portions folded (FIG. 2) to an open sleeve configuration (FIG. 3). In the configuration shown in FIG. 3, for example, the sleeve 80 can be filled with product, or otherwise can receive product therein. To complete the formation of the sleeve 80 from the substantially flat blank configuration shown in FIGS. 1-2 to the sleeve configuration shown in FIG. 3, generally, the panels 10, 20, 30, and 40 and adhesive panel 7 are folded along fold lines 9, 11, 21, and 31 to form the open sleeve configuration 80.
FIG. 4 shows the end flaps 14, 24, 34, 44 folded to form a bottom end to the sleeve/carton so as to define an open box configuration. To proceed from the open sleeve configuration shown in FIG. 3 to the open box configuration shown in FIG. 4, end flap 14 is folded along fold line 15, end flap 24 is folded along fold line 25, end flap 34 is folded along fold line 35, and end flap 44 is folded along fold line 45.

To enclose the top end of the carton in similar fashion to the formation of the bottom end, end flap 12 is folded along fold line 13, end flap 22 is folded along fold line 23 (or end flap segments 28 and 29 are folded along fold lines 26 and 29), end flap 32 is folded along fold line 33, end flaps 42 is folded along fold line 43 (or end flap segments 48 and 49 are folded along fold lines 46 and 49). Generally, end flaps 22 (or 28/29) and end flaps 42 (or 48/49) are folded inwardly toward an interior of the carton prior to folding end flaps 12 and 32. End flap 12 generally also is folded immediately prior to folding end flap 32, to dispose end flaps 12 and 32 in an overlapping configuration with flap 32 disposed over flap 12. Specifically, end flap 12 includes an adhesive panel segment 16 that is foldably connected along fold line 17. When the top end is closed in the configuration shown in FIG. 5, generally, an adhesive is applied to outer surface 3 of adhesive panel 16 to adhere to adhesive panel 16 to an interior surface of end flap 32. Alternatively, the interior surface of flap 32 can receive the adhesive.
FIG. 6 shows the carton 90 with the dispensing flap 70 being separated along tear line 72 (not shown) (or along tear lines 71, 73, 75, 76, 77, and 79 if individual tear lines are included). Generally, opening feature 74 is depressed slightly into the interior of the carton 90 to be separated along tear line 76. Then, separation of dispensing flap 70 continues along tear line 72 to separate dispensing portion 38 from the remainder portion 36 of the carton.
FIG. 7 shows the dispensing flap 70 entirely detached along tear line 72 (not shown) and opened to expose product P of carton 90. The dispensing flap 70 can be disposed in a display position on orientation to form a display header 95 (not shown). FIG. 8 shows the dispensing flap 70 being folded into position behind the product in the interior of the carton 90 to form display header 95.
FIG. 9 shows the display header 95 in display position. Generally, display header 95 is formed by folding dispensing flap 70 along fold line 17 (not shown) and placing dispensing flap 70 into the display position, such as with end flaps 12 and 32 in a facing relationship and with dispensing portion 38 received into cuts 62 and 64 (not shown).

In general, the blank, sleeve, or carton 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, sleeve, or carton 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, sleeve, or carton 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, sleeve, or carton may then be coated with a varnish to protect information printed on the blanks, sleeves, or cartons. The blanks, sleeves, or cartons may also be coated with, for example, a moisture barrier layer, on either or both sides of the blanks, sleeves, or cartons. The blanks, sleeves, or cartons 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 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 can 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 or creasing 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. 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. As various changes could be made in the above construction without departing from the 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. Furthermore, the scope of the present disclosure covers various modifications, combinations, alterations, etc., of the above-described embodiments that are within the scope of the claims. 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.
