DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

The present disclosure generally relates to various features for cartons, carriers, packages, containers, etc., that contain articles such as containers, bottles, cans, etc. The articles can be used for packaging food and beverage products, for example. 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 or carriers 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 beverage cans) as disposed within the carrier embodiments. In this specification, the terms “lower,” “bottom,” “upper,” and “top” indicate orientations determined in relation to fully erected and upright cartons.



FIG. 1 is a plan view of an exterior surface 2 of a blank 3, used to form a carrier 5, shown in FIGS. 4A and 4B, according to one embodiment of the disclosure. The carrier 5 can be used to house a plurality of articles such as containers C. The containers C can be, for example, cups for holding a food product (e.g., yogurt) and can have interconnected rims R, which can be separable along perforated lines extending between adjacent containers C. Alternatively, the carrier 5 can hold beverage cans or other containers. In the illustrated embodiment, the blank 3 is sized to form a carrier 5 that houses eight containers in a single layer in a 2×4 arrangement. But, it is understood that the blank 3 and/or carrier may be sized and shaped to hold containers of a different or same quantity in more than one layer and/or in different row/column arrangements (e.g., 1×6, 2×6, 2×3, 2×2, 2×6×2, 2×4×2, 2×9, etc.). In the illustrated embodiment, the carrier 5 has generally open ends, and the carrier generally wraps around the containers (e.g., the carrier may be referred to as a wrap-around carrier). The carrier 5 could be otherwise shaped and arranged such the ends are at least partially closed such as by end flaps (not shown) or other closing mechanisms.


The blank 3 has a longitudinal axis L1 and a lateral axis L2. In the illustrated embodiment, the blank 3 comprises a top panel 10 foldably connected to a first side panel 20 at a first lateral fold line 21, a first bottom panel 30 foldably connected to the first side panel 20 at a second lateral fold line 31, a second side panel 40 foldably connected to the top panel 10 at a third lateral fold line 41, and a second bottom panel 50 foldably connected to the second side panel 40 at a fourth lateral fold line 51. The blank 3 can include front and/or rear gusset panels connected to respective panels 10, 20, 30, 40, 50 without departing from the scope of the disclosure.


In the illustrated embodiment, the lateral fold lines 21, 41 are perforation lines with relatively widely spaced perforations and each of the lateral fold lines 31, 51 is a series of one hundred percent cuts separated by relatively smaller nicks for generally easy folding relative to the fold lines 21, 41. In the present embodiment, the lateral fold lines 31, 51 can be subjected to less tension during the formation and use of the carrier 5 since the portions of the side panels 20, 40 and the bottom panels 30, 50 adjacent the fold lines 31, 51 are not generally pulled tightly against the bottoms of the containers C due to the relatively large rims R of the containers C. Accordingly, the lateral fold lines 31, 51 can be configured to fold more easily during formation of the carrier 5, which can cause the fold lines to be weaker, without substantial risk of tearing of the fold lines. Alternatively, the fold lines 21, 31, 41, 51 could be otherwise shaped, arranged, and/or configured without departing from the disclosure. For example, any of the fold lines 21, 31, 41, 51 can incorporate such features as scores, creases, nicks, cuts, perforations, and other fold line features, or combinations thereof.


As shown in FIG. 1, the first bottom panel 30 can include primary female locking openings 96 and secondary female locking features 60. Each secondary female locking feature 60 can include a slit 62 forming a female locking opening 63 in the erected carrier 5 (FIG. 5). Each of the slits 62 extends generally laterally across the blank in the lateral direction L2. In the illustrated embodiment the slits 62 are not straight and include multiple turns, but the slits could be otherwise shaped without departing from the disclosure. As shown in FIG. 3, each of the slits 62 can include a central cut 64 and two end cut lines 65 extending from the central cut 64. The end cut lines 65 are generally arcuate as shown in FIG. 3; however, the end cut lines 65 could be otherwise shaped without departing from this disclosure. A fold line 66 generally extends between respective ends of the central cut 64 in each secondary female locking feature 60. In the illustrated embodiment the fold line 66 can be generally lateral and/or arcuate; however, the fold line could be otherwise shaped without departing from this disclosure. As shown in FIG. 3, the fold line 66 and the central cut 64 of the slit 62 can at least partially define a foldable locking flap 68 (broadly “opening flap”) for each secondary female locking feature 60. The locking flaps 68 each include a retention tab or protrusion 69 at the respective free edge thereof, generally opposite to the respective fold line 66. When the locking flaps 68 are folded out of plane with the remaining portion of the first bottom panel 30, a respective female locking opening 63 is formed. The locking flaps 68 or other features of the secondary female locking features 60 could be otherwise shaped, arranged, and/or configured without departing from the disclosure. For example, the first bottom panel 30 can include any suitable number of female locking features 60.


As shown in FIG. 1, the second bottom panel 50 can include primary male locking features 94 that are generally aligned with the primary female locking openings 96 in the first bottom panel 30 along respective longitudinal axes. Secondary male locking features 70 can extend from a main portion of the second bottom panel 50 and be foldably connected to the main portion along a fold line 71. In the illustrated embodiment, the fold line 71 is a cut-crease line; however, the fold line 71 could be any suitable line of weakening (e.g., fold line, crease line, score, cut, etc.) without departing from this disclosure. Each of the secondary male locking features 70 can include a male locking projection 72 and a proximal portion 74 extending between each male locking projection 72 and the fold line 71. The male locking projections 72 are generally aligned with and shaped for being received in a respective female locking feature 60. In the illustrated embodiment, each male locking projection 72 is foldably connected to the respective proximal portion 74 at a fold line 76 that extends across a narrow neck portion 77 of the secondary male locking feature 70. As shown in FIG. 2, the male locking projections 72 can have respective shoulders 78 that extend laterally outward from the narrow neck portion 77. The secondary male locking features 70 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.


In the illustrated embodiment, as shown in FIG. 2, each of the male locking projections 72 has a retention feature 80 comprising a retention flap 81. The retention flap 81 can be formed by a retention cut 82 in the male locking projection 72. In one embodiment, the retention cut 82 has a lateral portion 84 and two oblique end portions 86, 88, but the retention cut 82 could be otherwise shaped, arranged, and/or configured to include other shapes (e.g., arcuate, orthogonal, straight, etc.). In one embodiment, the retention flap 81 is at least partially defined by a lateral cut 90 parallel to and spaced apart from the lateral portion 84 of the retention cut 82. The ends of the lateral cut 90 can be spaced apart from the respective ends of the oblique end portions 86, 88 of the retention cut 82. Accordingly, the lateral cut 90 can generally form a fold line and help facilitate folding of the retention flap 81 out of plane with the male locking projection 72. The lateral cut 90 could be lines of weakening other than a cut (e.g., fold line, crease line, cut/crease line, etc.) without departing from this disclosure.


The retention features 80 can be otherwise shaped, arranged, and/or configured without departing from the disclosure. For example, as shown in FIG. 2A, one or more of the male locking projections 72 can include a retention feature 80′ that defines an opening 82′ for at least partially receiving the retention protrusion 69 of the locking flap 68.


As shown in FIGS. 1 and 2, the secondary female locking features 60 and the secondary male locking features 70 can be interlocked to form respective locking features 100 (FIGS. 4B-8) in the carrier 5 formed from the blank 3. The locking features 100 can be formed when the male locking projections 72 are inserted through the respective slits 62. The locking flaps 68 can fold upwardly to form the respective female locking openings 63, and the shoulders 78 of the male locking projections 72 can engage the end cut lines 65 of the slits 62 to help prevent withdrawal of the male locking projections 72. Accordingly, when the locking features 100 are formed, the shoulders 78 can be positioned above the first bottom panel 30 proximate the respective end cut lines 65. The foldable flap 68 is also biased against the male locking projection 72 to help prevent disengagement of the male locking projection 72 with a respective female opening 63. In the illustrated embodiment, at least a portion of each locking flap 68 (e.g., retention protrusion 69) can at least partially engage the retention feature 80 in the respective male locking projection 72 to further help prevent disengagement of the secondary male locking features 70 from the secondary female locking features 60.


As shown in FIG. 2, each of the primary male locking projections 94 is at least partially defined by a curved cut 95 in the second bottom panel 50 so that the primary male locking projections 94 generally extend from the respective proximal portions 74 of the secondary male locking features 70. As the secondary male locking features 70 are pivoted along the fold line 71, the primary male locking projections 94 can pivot out of the plane of the second bottom panel 50 in the opposite direction to the respective proximal portions 74. For example, the proximal portions 74 can be folded downwardly along the lateral fold line 71 causing the primary male locking projections 94 to pivot upwardly with respect to the remainder of the second bottom panel 50. In the illustrated embodiment, the primary male locking projections 94 and the primary female locking openings 96 are generally aligned with the respective secondary male locking features 70 and secondary female locking features 60 in the blank 3. However, the primary male locking projections 94 and the primary female locking openings 96 can be generally offset from the secondary male locking features 70 and the secondary female locking features 60 without departing from the disclosure.


As shown in FIG. 1, the blank 3 optionally can include knee locks or push-in features 102 extending in the first side panel 20 and the first bottom panel 30, generally aligned with the second lateral fold line 31. Each of the push-in features 102 can include a first push-in panel 104 foldably connected to a second push-in panel 106 along a lateral fold line 108. In the illustrated embodiment, the lateral fold lines 108 are offset from the second lateral fold line 31 towards the first bottom panel 30. The first push-in panel 104 and the second push-in panel 106 of each of the push-in features 102 can be foldably connected to the respective first side panel 20 and first bottom panel 30 along respective lateral fold lines 110, 112. In the illustrated embodiment, the lateral fold lines 108, 112 can be cut-crease lines (e.g., creases or scores extending from the ends of a cut) and the lateral fold line 110 can be a score or crease. Alternatively, the lateral fold lines 108, 110, 112 could be any suitable lines of weakening (e.g., fold line, crease line, cut/crease line, score, cut, etc.) without departing from this disclosure. The push-in features 102 can include openings 114 disposed on either side of the push-in panels 104, 106. The push-in features 102 could be omitted or otherwise shaped, arranged, and/or configured without departing from the disclosure. For example, the blank 3 could include any suitable number of push-in features 102. Additionally, push-in features 102 could extend in the second side panel 40 and the second bottom panel 50 in addition to or instead of the push-in features 102 in the first side panel 20 and the first bottom panel 30.


As shown in FIGS. 4A-8, the carrier 5 is formed from the blank 3 by wrapping the blank 3 around the containers C and overlapping the first and second bottom panels 30, 50 to at least partially form an interior 120 of the carrier 5. In the illustrated embodiment, the top panel 10 is placed on the interconnected rims R of the container C, the side panels 20, 40 are folded downwardly along respective lateral fold lines 21, 41, and the bottom panels 30, 50 are inwardly folded along respective fold lines 31, 51 so that the first bottom panel 30 generally overlaps the second bottom panel 50. In one embodiment, as the first bottom panel 30 is folded along the second lateral fold line 31, the push-in features 102 are pushed inwardly between the respectively adjacent containers C, as shown in FIG. 4B. Accordingly, the push-in panels 104, 106 are folded along fold lines 108, 110, 112 so that the push-in panel 104 is generally horizontal and the push-in panel 106 is generally vertical in the interior 120 of the carrier 5. The push-in panels 104, 106 can help prevent the containers C, which are connected at the rims R, from translating laterally in the carrier 5 to help prevent the containers from sliding out of the carrier 5 through the open ends. The push-in features 102 can be otherwise formed and can otherwise interface with the containers C without departing from the disclosure.


In the illustrated embodiment, the bottom panels 30, 50 can be interlocked by engaging the primary male locking projections 94 with the primary female locking openings 96 and inserting the male locking projections 72 into the female locking openings 63. In one particular embodiment, the secondary male locking features 70 are folded downwardly along the lateral fold line 71 causing the primary male locking projections 94 to pivot upwardly relative to the remainder of the second side panel 50. The primary male locking projections 94 can be inserted into the primary female locking openings 96. The male locking projections 72 can be folded upwardly along the fold lines 76 to be generally perpendicular to the respective proximal portions 74 of the secondary male locking features 70, and the proximal portions 74 can be folded upwardly along the lateral fold line 71 and into face-to-face contact with the first bottom panel 30. Accordingly, the male locking projections 72 are engaged with the secondary female locking features 60. Particularly, the male locking projections 72 can be inserted into the slits 62 so that the leading edges of the male locking projections 72 press against the respective locking flaps 68 to fold them upwardly about the fold lines 66, forming the female locking openings 63. The first bottom panel 30 can separate somewhat adjacent the end cut lines 65 to allow the male locking projections 72 to pass through the slits 62.


In the illustrated embodiment, when the proximal portions 74 are in face-to-face contact with the first bottom panel 30, the respective male locking projections 72 are fully inserted into the secondary female locking features 60 so that the narrow neck portion 77 is disposed in the female locking opening 63 and the shoulders 78 are disposed above the first bottom panel 30 proximate the end cut lines 65 (FIGS. 6 and 7). When the bottom panels 30, 50 are positioned in their final, locked and loaded orientation, the shoulders 78 can be out of alignment with the cuts 62 in the first bottom panel 30 so that the shoulders contact a portion of the first bottom panel 30 to help prevent withdrawal of the male locking projections 72 from the female locking openings 63. The male locking projections 72 can interact and engage the female locking openings 63 by other positioning steps or alternative features and/or arrangements without departing from the disclosure.


In one embodiment, the male locking projections 72 are held in a generally upright position in the inside of the carrier 5 relative to the first and second bottom panels 30, 50 by the engagement of the locking flaps 68 with the retention feature 80 of a respective male locking projection 72. As shown in FIGS. 6-8, the foldable flaps 68 are folded upward relative to the bottom panel 30 and the retentions protrusions 69 at the free edges of the locking flaps are pressed against the retention flaps 81 causing them to fold out of plane with the rest of the respective male locking projections 72. As shown in FIG. 8, the retention protrusion 69 is inserted through the opening 101 in the male locking projection caused by folding the retention flap 81 at fold line 90. Alternatively, the retention feature 80′ of FIG. 2A can be used, wherein the retention protrusion 69 is inserted through the opening 82′ in the male locking projection 72. The engagement of the retention protrusion 69 with the edge 103 of the male locking projection 72 at the opening 101 assists in maintaining the male locking projections in the upright position. For example, when one of the male locking projections 72 is pushed or pulled toward a respective female locking opening 63, the edge 103 engages the retention protrusion 69 of the locking flap 68, which can push against the first bottom panel 30 at the fold line 66 to help resist the movement of the male locking projection 72 toward the female locking opening 63. The secondary male locking features 70 can be locked or engaged with the female locking features 60 by otherwise positioning the aspects and features of the blank 3 without departing from the disclosure.


In one embodiment, the engagement between the retention protrusions 69 with retention features 80, 80′ can help hold the locking features 100 together even under some movement of the bottom panels 30, 50. For example, as shown in FIG. 5, the side panels 20, 40 can be in close contact and/or pulled tightly against the rims R of the containers C adjacent the respective fold lines 21, 41. The bottoms of the containers C can be generally smaller than the rims R, so the portions of the side panels 20, 40 and the bottom panels 30, 50 adjacent the respective fold lines 31, 51 can be spaced apart from the containers C. This spacing can lead to some relative movement of the bottom panels 30, 50, which could help force the male locking projections 72 toward the female locking openings 63. However, the engagement of the retention protrusion 69 of the locking flap 68 with the retention feature 80 for each locking feature 100 can help prevent the male locking projections 72 from withdrawing from the respective locking opening 63.


In an alternative embodiment, the carrier 5 can include one or more locking features 100 as described above in conjunction with a suitable number alternative locking features (not shown) to interlock the bottom panels 30, 50.


In general, the blank may be constructed from paperboard having a caliper (e.g., 14-point board) 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.


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.


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 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. Additionally, the disclosure shows and describes only selected embodiments, but various other combinations, modifications, and environments are within the scope of the disclosure 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.
