DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT
The present disclosure generally relates to cartons that contain articles, for example, containers such as bottles, cans, etc. The articles can be used, for example, for packaging food and beverage products. The articles can be made from materials suitable in composition for packaging the particular food or beverage item, and the materials include, but are not limited to, aluminum and/or other metals; glass; plastics such as PET, LDPE, LLDPE, HDPE, PP, PS, PVC, EVOH, and Nylon; and the like, or any combination thereof
Cartons according to the present disclosure can accommodate articles of any shape. For the purpose of illustration and not for the purpose of limiting the scope of the disclosure, the following detailed description describes beverage containers (e.g., aluminum cans or glass beverage bottles) as disposed within the carton embodiments. In this specification, the terms “inner,” “outer,” “lower,” “bottom,” “upper,” and “top” indicate orientations determined in relation to fully erected and upright cartons.
As described herein, cartons may be formed by multiple overlapping panels and/or end flaps. Such panels and/or end flaps may be designated in relative terms to one another, e.g., “first”, “second”, “third”, etc., in sequential or non-sequential reference without departing from the disclosure.
FIG. 1 is a plan view of the interior side 1 of a blank, generally indicated at 3, used to form a carton 5 (FIG. 14) according to one exemplary embodiment of the disclosure. The carton 5 can be used to house a plurality of articles such as containers in the form of beverage cans C (FIG. 42). The carton 5 includes features for facilitating conservation of board material when housing the cans C in a nested arrangement. Additionally, the carton 5 can have a different visual configuration than conventional cartons, for example, so that carton 5 can be more noticeable and/or more easily distinguishable from other cartons on display. As described herein, the carton 5 has features to increase the strength of the carton 5 and opening features to facilitate access to the cans C.
Referring additionally to FIG. 2, in the first embodiment, the carton 5 is sized and configured to contain thirteen cans C in a single layer in a “nested” arrangement N13 having two outer rows of four cans C per row and one inner row of five cans C per row. FIG. 2 also shows various nested pack arrangements for use with carton 5 or other cartons of the disclosure, which include various arrangements for cans C and other containers, such as bottles B. The arrangements N1-N5 and N13 and/or other arrangements shown and not shown in the illustrated embodiments can be considered “fully nested” arrangements. In one embodiment, a fully nested arrangement of containers can have at least one outer row and at least one inner row, wherein each of the inner row(s) can have at least one more container than an outer row. For example, nested arrangement N1 can have six bottles B in each of two outer rows and seven bottles B in each of two inner rows, wherein each of the outer rows is nested with a respectively adjacent inner row. In one embodiment, at least the nesting arrangements N6-N12 can be considered “inverted” or “internal” nesting arrangements since one or more of the interior rows of bottles B or cans C are generally shorter than the outer rows of containers B or C. Other nested or non-nested arrangements of the containers including bottles B or cans C could be provided without departing from the disclosure.

In the illustrated embodiment, the dispenser panel 102 comprises portions of the bottom panel 10, the first side panel 20, the top panel 30, and the gusset panels 16c, 16d, 32c, 32d. In one embodiment, the dispenser panel 102 includes access features 106 in each of the bottom panel 10 and top panel 30 for grasping the dispenser panel 102 and tearing along dispenser tear line 104. The blank 3 could have other features or the features shown could be otherwise shaped, arranged, and/or configured without departing from the disclosure.
With continued reference to FIG. 1, and referring additionally to FIGS. 3-14, various features and steps of one exemplary method of forming the carton 5 from the blank 3 are shown. As shown in FIG. 3, the blank 3 is folded about the fold lines 51, 21, 31, and 41 so that the second side panel 40 at least partially overlaps and is adhered to the third side panel 50 to form a side panel 46, and the side panel 46 and the first side panel 20 are positioned relative to the bottom panel 10 and the top panel 30 to form an open-ended sleeve 121 with an interior 109. The interior 109 of the open-ended sleeve 121 form the interior 109 of the carton 5. In one embodiment, the cans C are grouped together and loaded into the open-ended sleeve 121 in the nested configuration N13 shown in FIG. 2. One of the ends 71, 73 can be closed prior to loading the cans C or the ends 71, 73 can remain open during loading of the cans C without departing from the disclosure. Further, the cans C could be arranged in a different nesting configuration without departing from the disclosure.
Still referring to FIG. 1, and as shown in FIGS. 4-9, the closing of the end 71 of the carton 5 (FIG. 14) will be described, but the closing of the other end 73 can be identical to the end 71 described herein. Alternatively, the end 73 can have other features and/or could have other closing steps without departing from the disclosure. As shown in FIG. 4, the bottom end flap 12 can be upwardly folded about fold line 13 and the gusset portions 12c, 12d are folded inwardly at the fold line 75 in the direction of arrow A1, e.g., in a peaked condition, so that the gusset portions 12c, 12d overlap and the distal portion 12b is correspondingly rotated toward the side panel 46. Next, the side panel 46 that includes overlapped side end flaps 42, 52 is folded inward in the direction of A2 (FIG. 4) about fold lines 43, 53 to the position of FIG. 5. The distal portions 42b and 52b may also be at least partially folded about respective fold lines 85, 79 in such a position. As shown in FIG. 5, the distal portion 12b of the bottom end flap 12 is positioned to be overlapped by the notch 95 of the side end flap 52 such that a portion of the distal portion 12b of the bottom end flap 12 is exposed adjacent the side end flap 52. Also shown in FIG. 5, the base portions 42a, 52a of the side end flaps 42, 52 are positioned to be oblique relative to the remainder of the side panel 46 upon the folding described herein. As shown, the gusset 54 is activated when the side end flaps 42, 52 are folded inward to partially close the end 71 so that the gusset panels 56, 58 are folded about fold line 59 such that the gusset panels 56, 58 are in face-to-face contact and overlap with the side end flap 42 overlapping the gusset panel 56. In embodiments, the gusset 54 may be directly activated by a user.
As shown in FIGS. 5 and 6, the bottom end flap 16 is folded in a similar manner as the bottom end flap 12. In particular, the two gusset portions 16c, 16d are folded relative to each other about the fold line 77 and into face-to-face contact and the distal portion 16b is correspondingly toward the side panel 20 as the end flap 16 is closed. The top end flap 32 can be similarly closed, as shown, by folding the gusset portions 32c, 32d relative to each other about fold line 83 and into face-to-face contact with the distal portion 32b correspondingly rotated toward the side panel 20. As shown, the side end flap 22 is closed by folding along the fold line 25 and a portion of the fold line 81. As the side end flap 22 is closed over the side panel 46 in partial overlapping relation, the distal portion 16b of the bottom end flap 16 and the distal portion 32b of the top end flap 32 are positioned so that the respective notches 91, 93 overlap portions of the respective distal portions 16b, 32b, with portions of the distal portion 16b, 32b exposed adjacent the side end flap 22, as shown. The distal portion 22b of the side end flap 22 is thus folded to overlap a portion of the distal portions 42b, 52b of the overlapped side end flaps 42, 52 and can be adhered to the distal portions 42b, 52b in such position. Also as shown, as the end flap 22 is folded, the distal portions 16b, 32b of the respective end flaps 16, 32 are urged against portions of the flaps 42, 52, 12, with portions of the distal portions 16b, 32b exposed adjacent the respective cutouts 91, 93. With continued reference to FIG. 1, and as shown in FIGS. 7-9, the bottom end flap 14 is upwardly folded to at least partially overlap the overlapped distal portions 12b, 16b, 22b, 42b, 52b of the respective end flaps 12, 16, 22, 42, 52. Similarly, the top end flap 34 is folded to at least partially overlap the overlapped distal portions 32b, 22b, 42b, of the respective end flaps 32, 22, 42 as well as the bottom end flap 14. In embodiments, the top end flap 34 and/or the bottom end flap 14 can overlap portions of one or more of the gusset panels 32c, 32d, 16c, 16d, 12c, 12d, 56, and 58. The overlapping portions of flaps 12, 16, 22, 42, 52, 14, 34 can be secured to one another with an adhesive such as glue. In this regard, the exposed portions of the end flaps 32b, 16b adjacent the respective notches 91, 93 of the end flap 22 are available as adhesion surfaces to respective overlapping end flaps 34, 14, and the exposed portion of the end flap 12 adjacent the cutout 95 are available as adhesion surfaces to respective overlapping end flap 32 to provide a secure closure 100 at the end 71 of the carton 5 (FIG. 14). The end 71 of the carton 5 can be closed by other steps than shown and described herein without departing from the disclosure.
Still referring to FIG. 1, and as shown in FIGS. 10-13, the second end 73 of the carton 5 can be closed in a similar manner as described above for the first end 71 of the carton 5. In particular, the gussets 54, 64 and end flaps 12, 16 can be activated, e.g., folded inwardly about respective fold lines 59, 69 and 75, 77 such that the respective gusset panels 56 and 58, 66 and 68, 12c and 12d, and 16c and 16d are in face-to-face contact, with the distal portion 12b of the end flap 12 rotated toward the side panel 46 and the distal portion 16b of the end flap 16 rotated toward the side panel 20. As shown, the overlapped side panels 42, 52 can be folded about respective fold lines 43, 53 such that the cutout 95 of the distal portion 52b of the side panel 52 overlaps a portion of the distal portion 12b of the end flap 12. In this regard, a portion of the distal portion 12b of the end flap 12 is exposed adjacent the side panel 52. The top panel 22, as shown, can also be folded at fold line 81 such that a portion of the top panel 22 overlaps portions of the side panels 42, 52. The bottom end flap 14 can then be folded upwardly to at least partially overlap the overlapped distal portions 12b, 16b, 22b, 42b, 52b of the respective end flaps 12, 16, 22, 42, 52. Similarly, the top end flap 34 is folded to at least partially overlap the overlapped distal portions 22b, 42b, of the respective end flaps 32, 22, 42 as well as the bottom end flap 14. In embodiments, the top end flap 34 and/or the bottom end flap 14 can overlap portions of one or more of the gusset panels 32c, 32d, 16c, 16d, 12c, 12d, 56, 58, 66, and 68. The overlapping portions of flaps 12, 16, 22, 42, 52, 14, and 34 can be secured to one another with an adhesive such as glue. The end 73 of the carton 5 can be closed by other steps than shown and described herein or can have a different configuration than described herein without departing from the disclosure. For example, in embodiments, the end 73 of the carton 5 can have a similar configuration to the end 71 of the carton 5 described above.
As shown in FIG. 14 each of the ends 71, 73 of the carton 5 have a central portion 131 that is generally perpendicular to the side panels 20, 46, and is generally aligned with the fold lines 15, 35. The ends 71, 73 have two oblique side portions 133, 135 on a respective side of the central portion 131 that are respectively aligned with the fold lines 13, 17. In the illustrated embodiment, the configuration of the ends 71, 73 with central portion 131 and oblique side portions 133, 135 facilitates receiving the nested arrangement N13 (FIG. 2) of cans C. Such a configuration of the carton 5 may conserve material, for example, as compared to a conventional carton that lacks oblique side portions. Further, the configuration of the carton 5 may be readily distinguishable from other conventional cartons. Either or both of the ends 71, 73 of the carton 5 could be otherwise shaped, arranged, positioned, and/or configured without departing from the disclosure, and the nested arrangement N13 could be an alternative nested arrangement (e.g., nested arrangement N1-N12, or a nested arrangement that is otherwise configured) without departing from the disclosure.
As also shown in FIG. 14, the carton 5 can be carried by the handle 105 by rotating the loaded and closed carton 5 so that the side panel 20 is facing downward and the side panel 46 formed by the overlapped side panels 40, 50 in the upright position shown. The handle openings 97, 99 can be accessed by a user and a handle portion 98 between the handle openings 97, 99 formed by portion of the side panel 40 and/or the side panel 50 can be grasped to lift and carry the carton 5. The handle 105 could be otherwise shaped, arranged, configured, and/or omitted without departing from the disclosure.
As shown in FIGS. 15 and 16, the cans C in the assembled, loaded, and closed carton 5 can be accessed activating the dispenser 107 on the closed end 71 of the carton 5. The dispenser 107 is activated by removing the dispenser panel 102 by tearing along the tear line 104 to create a dispenser opening 103 for removal of the cans C. As shown, the arrangement of the secure closure 100 remains intact above the dispenser opening 103 to retain cans C within the carton 5. As also shown, the portion of the side panel 20 below the dispenser opening 103 provides a lip 108 that partially engages a container C for removal from the carton 5. As shown, the container C that partially rests upon the lip 108 can be grasped by top and bottom portions of the container C (which is disposed on its side) along lateral portions of the dispenser opening 103 provided by the removal of access features 106. Upon removal of the container C from the lip 108, a sequentially next container C from the interior of the carton 5 can roll or fall into position in the lip 108 for access by a user. As shown, the lip 108 may cant or tilt slightly outward from the carton 5 under the weight of a container C. The dispenser 107 can be otherwise shaped, arranged, configured, and/or omitted without departing from the disclosure.
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 nesting arrangements and/or the features of the blanks and cartons of the various embodiments can be incorporated into a carton or blank having any carton style or panel configuration. The carton styles and panel configurations described above are included by way of example.
The blanks according to any of the embodiments of the present disclosure can be, for example, formed from coated paperboard and similar materials. For example, the interior and/or exterior sides of the blank can be coated with a clay coating. The clay coating may then be printed over with product, advertising, price coding, and other information or images. The blank may then be coated with a varnish to protect any information printed on the blank. The blank 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 blank may be constructed of paperboard of a caliper such that it is heavier and more rigid than ordinary paper. The blank can also be constructed of other materials, such as cardboard, hard paper, or any other material having properties suitable for enabling the carton to function at least generally as described herein. The blank 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 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, 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.
