[0028] The present disclosure generally relates to cartons 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.

[0029] 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., glass beverage bottles) as disposed within the carton embodiments. In this specification, the terms "lower," "bottom," "upper" and "top" indicate orientations determined in relation to fully erected and upright cartons.

[0030] Fig. 1 is a plan view of the exterior side 1 of a blank, generally indicated at 3, used to form a carton 5 (Fig. 3) according to one exemplary embodiment of the disclosure. The carton 5 can be used to house a plurality of articles such as containers C (Fig. 11). In the illustrated embodiment, the carton 5 is sized to house twelve containers C in a single layer in a 3x4 arrangement, but it is understood that the carton 5 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., 1x6, 3x6, 2x6x2, 4x5, 3x5, 2x9, 2x6, 3x4, etc.). In one embodiment, the carton 5 has a dispenser 7 for accessing the containers C in the carton, hi the illustrated embodiment, the carton 5 includes a handle, generally indicated at 11, for grasping and carrying the carton. As will be discussed below in more detail, the carton 5 includes an insert 205 for restraining the movement of the containers C and for reinforcing the carton.

[0031] The carton blank 3 has a longitudinal axis Ll and a lateral axis L2. hi 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 bottom panel 30 is foldably connected to the first side panel 20 at a second lateral fold line 31. A second side panel 40 is foldably connected to the bottom panel 30 at a third lateral fold line 41. In the illustrated embodiment, the blank 3 includes an adhesive flap 50 foldably connected to the top panel 10 at a fourth lateral fold line 52. In alternative embodiments, the blank 3 can be arranged so that the top panel 10 is foldably connected to both the first and second side panels 20, 40, or the blank 3 can have other alternative panel arrangements.

[0032] The top panel 10 is foldably connected to a first top end flap 12 and a second top end flap 14. The first side panel 20 is foldably connected to a first side flap 22 and a second side flap 24. The bottom panel 30 is foldably connected to a first bottom end flap 32 and a second bottom end flap 34. The second side panel 40 is foldably connected to a first side flap 42 and a second side flap 44. When the carton 5 is erected, the top and bottom end flaps 12 and 32 and side end flaps 22 and 42 close a first end 51 of the carton, and the top and bottom end flaps 14 and 34 and side end flaps 24 and 44 close a second end 53 of the carton (Fig. 3). In accordance with an alternative embodiment of the present disclosure, different flap arrangements can be used for at least partially closing the ends 51, 53 of the carton 5.

[0033] The top and bottom end flaps 12 and 32 and side end flaps 22 and 42 extend along a first marginal area of the blank 3, and are foldably connected at a first longitudinal fold line 62 that extends along the length of the blank. The top and bottom end flaps 14 and 34 and side end flaps 24 and 44 extend along a second marginal area of the blank 3, and are foldably connected at a second longitudinal fold line 64 that also extends along the length of the blank. The longitudinal fold lines 62, 64 may be, for example, substantially straight, or offset at one or more locations to account for blank thickness or for other factors.

[0034] In the illustrated embodiment, the carton blank 3 includes features to form the carton 5 having tapered ends 51, 53. That is, the blank 3 includes diamond comer panels 67, 69 that connect respective side end flaps 22, 42, 24, 44 to a respective one of the first side panel 20 and the second side panel 40. The diamond corner panels 67, 69 are configured to allow the ends 51, 53 to taper from the bottom to the top with a respective edge of the bottom panel 30 at one end being located farther from the centeiiine of the carton than a respective edge of the top panel 10 at the second end. The containers C having a wide bottom B and narrow top T can be tightly held in the carton with the narrow tops of the containers located adjacent to the ends 51, 53 being located in close proximity to the portions of the fold lines 62, 64 connecting the top end flaps 12, 14 to the top panel, hi alternative embodiments, the carton 5 could be otherwise shaped, arranged, and/or configured. For example, the carton 5 could have substantially straight sides and ends and could be without the diamond corner panels 67, 69 without departing from the disclosure.

[0035] As shown in Fig. 1 , the features that form the handle 11 of the carton 5 include a first elongate handle flap 71 foldably connected to the top panel 10 at a lateral fold line 73, and a second elongate handle flap 75 foldably connected to the top panel at a lateral fold line 77. The handle 11 may be otherwise shaped and located in the carton 5 without departing from the scope of this disclosure.

[0036] Fig. 2 illustrates an exterior surface of an insert blank 203 used to form a reinforcing insert 205 (Fig. 10) for use in the carton 5. In the illustrated embodiment, the insert blank 203 includes a central panel 206, two reinforcing end flaps 212, 214 respectively foldably connected to the central panel 206 at respective fold lines 215, 217 at opposite ends of the central panel. The insert blank 203 has two reinforcing side flaps 219, 221 foldably connected to the central panel 206 at respective fold lines 223, 225 at opposite sides of the central panel. In the illustrated embodiment, the reinforcing side flap 221 comprises a handle reinforcing portion 229 that is removably attached to a article restraining portion 231 at a tear line 233. The article restraining portion 231 includes three panels 237, 239, 241 that are independently positionable at respective fold lines 225, 243, 245.

[0037] As shown in Figs. 4-9, in one exemplary embodiment, the carton 5 can be assembled by initially adhering the insert blank 203 to the top panel 10 of the carton blank 3. As shown in Fig. 4, adhesive in the form of glue 275, 277, 279, 281 is applied to the interior surface of the top panel 10 prior to placing the insert blank 203 in face-to-face contact with the top panel. After placing the insert blank 203 on the top panel 10 as shown in Fig. 5, adhesive in the form of glue 283 is applied to the exterior surface of the handle reinforcing portion 229 of the reinforcing side flap 221. Next, the blank 3 of Fig. 5 is folded about fold line 225 (in the direction of arrow Al) so that the reinforcing side flap 221 is folded over the central panel 206 of the insert blank 203 so that the reinforcing side flap is in face-to-face contact with the central panel. The glue 283 on the handle reinforcing portion 229 adheres the reinforcing side flap 221 to the central panel as shown in Fig. 6. Next, adhesive in the form of glue 287 is applied to the side panel 20 as indicated in Fig. 6. Next, the blank 3 is folded about working score line 21 (in the direction of arrow A2) so that the side panel 20 overlaps the insert blank 203. A portion of the side panel 20 is brought into face-to-face contact with the reinforcing side flap 221. When the side panel 20 is folded about score line 21, the glue 287 is brought into contact with the panel 237 of the container reinforcing portion 231 so that the panel 237 is adhered to the side panel 20. When the side panel 20 is folded in the direction of arrow A3 (Figs. 7 and 8), the container reinforcing portion 231 that is adhered to the side panel separates from the handle reinforcing portion 229 that is adhered to the central panel 206 along tear line 233.

[0038] The handle reinforcing portion 229 of the insert 205 remains secured to the central panel 206 below the handle 11 in the top panel 10 to provide three layers of material in the area of the handle (the top panel 10, the central panel 206, and the handle reinforcing portion 229). The container reinforcing portion 231 remains foldably connected to the central panel 206 and is adhesively secured to the side panel 20. As shown in Fig. 11, the portions 239, 241 of the container reinforcing portion 231 are free from attachment to the top panel 10 or the side panel 20 and are spaced in from the comer of the carton 5 at the fold line 21 to restrain the containers C that are adjacent to the side panel 20.

[0039] In one embodiment, the reinforcing side flap 219 is foldable connected to the central panel 206 and is free from attachment to the side panel 40 and adhesive flap 50. The reinforcing side flap 219 extends downward from the central panel and is spaced in from the corner of the carton 5 at the fold line 52 to restrain the containers C that are adjacent to the side panel 40.

[0040] In the illustrated embodiment, the reinforcing end flaps 212, 214 are downwardly folded at a respective fold line 215, 217 in the insert 205 when a respective top end flap 12, 14 is downwardly folded to close an end 51, 53 of the carton 5. In one embodiment, the fold lines 215, 217 are each spaced apart from a respective portion of the longitudinal fold lines 62, 64 that connect a respective top end flap 12, 14 to the top panel and are closer to the interior of the carton 5 than the longitudinal fold lines by a distance D (Fig. 5). In one embodiment, the distance D can be at least about 3 mm (0.118"), or the distance D could be less than 3 mm without departing from the scope of this disclosure. The spacing of the fold lines 215, 217 inward closer to the interior of the carton 5 from the fold lines 62, 64 allows the reinforcing end flaps 212, 214 to provide a tighter restraint on movement of the containers C that are adjacent a respective end 51, 53 of the container.

[0041] As shown in Figs. 10-12, the reinforcing end flaps 212, 214, the reinforcing side flap 219, and the container reinforcing portion 231 of the reinforcing side flap 221 form an article restraining structure 202 of the insert 205 that provides restraint to the tops of the containers C on the four sides of the carton 5. In this manner, the containers C are prevented from excessive movement in the carton.

[0042] Fig. 13 is an enlarged view of the insert blank 203 showing a portion of the tear line 233. The tear line 233 includes a straight cut line 260 with a series of spaced apart nicks 261 that are portions of material that are torn to separate the handle reinforcement portion 229 from the container reinforcement portion 231. Alternatively as shown in Fig. 14, the tear line 233 could be formed by a cut line 270 having V-shaped portions and two nicks 271 on each V-shaped portion of the cut. Alternatively, the tear line 233 could be other configurations.

[0043] Fig. 15 illustrates an alternative embodiment of an insert blank 303 for use in forming an insert 305 placed in the carton 5. Accordingly, like or similar features may be indicated by like or similar reference numbers from the first embodiment. The blank 303 has a central panel 306, reinforcing end flaps 314, 312, and reinforcing side flaps 319, 331. The insert 305 differs from the first embodiment in that the second embodiment does not include a handle reinforcing portion 229. The reinforcing side flap 331 functions in a similar manner as the reinforcing portion 231 of the reinforcing side flap 221 of the first embodiment. The reinforcing side flap 331 has respective portions or panels 337, 339, 341 respectively foldably connected at fold lines 325, 343, 345. In the article retaining structure 302 formed from the insert 305, panel 337 can be adhesively secured to the side panel 20 and the other two panels 339 and 341 can being free from attachment to the side panel 20 or the top panel 10.

[0044] Figs. 16-19 illustrate the second embodiment of the insert blank 303 being formed into an insert 305 that is attached to the carton 5 and has article retaining structure 302. The insert 305 is formed in a similar manner as illustrated above for the insert 205 of the first embodiment. First, the central panel 306 is attached to the top panel 10. Next, the reinforcing side flap 331 is folded about fold line 325 and temporarily attached to the central panel 306 by glue 383 (Fig. 17). Alternatively as shown in Fig. 18, the reinforcing side flap 331 could be folded at fold line 345 without departing from the scope of the disclosure. Next, glue can be applied to the side panel 20 in a similar manner as the first embodiment. When the carton 5 is erected by folding about fold line 21 in the direction of arrow A5, the side panel 20 is brought into fact-to-face contact with the side reinforcing flap 331, so that the glue contacts the panel 337 of the reinforcing side flap 331. When the carton 5 is further formed by folding in the direction of arrow A6 (Fig. 19), the reinforcing side flap 331 folds relative to the central panel 306 at the fold line 325.

[0045] As shown in Fig. 19 the portions 339, 341 of the reinforcing side flap 331 are free from attachment to the top panel 10 or the side panel 20 and the portion 337 is adhesively attached to the side panel 20. The reinforcing end flaps 312, 314 are located in a similar manner as the first embodiment to restrain the containers C that are adjacent the ends 51, 53 of the carton. As with the first embodiment, the article restraining structure 302 comprises the reinforcing end flaps 312, 314 and the reinforcing side flaps 319, 331 that are positioned to be folded downward from the central panel 306 and have a portion free from attachment to the carton 5 so that the reinforcing end flaps and reinforcing side flaps contact the tops of containers C loaded in the carton at the sides and ends of the carton.

[0046] Figs. 20 and 21 illustrate an alternative embodiment of the insert blank 303 that includes a tab 384 on a free edge of the reinforcing side flap 331. The tab 384 is positioned to fit within one of the handle opening 386 of the central panel 306 when the reinforcing side flap 331 is folded over the central panel. The retention features of the tab 384 in the opening 386 eliminates the need for glue 383 to temporarily hold the reinforcing side flap 331 in contact with the central panel 306 when the glue 287 is applied to the side panel 20. The insert blank 303 may have alternative retention features without departing from the disclosure. Further, the insert blank 303 can be otherwise shaped, arranged and/or configured without departing from the disclosure.

[0047] Fig. 22 illustrates an alternative embodiment of an insert blank 303 for use in forming an insert 305 placed in the carton 5. Accordingly, like or similar features may be indicated by like or similar reference numbers from the previous embodiments. The embodiment of Fig. 22 differs from the embodiment of Fig. 15 in that the handle features in the central panel 306 of Fig. 22 vary from the handle features shown in the embodiment of Fig. 15. Also, in the embodiment of Fig. 25, the fold lines 343, 345 in the reinforcing flap 331 that connect the portions 339, 341 to the central portion 337 of the flap have a fewer amount of nicks spaced across the length of the fold lines as compared to the embodiment of Fig. 17. The insert blank 303 of Fig. 22 may be otherwise shaped, arranged, and configured without departing from this disclosure.

[0048] Fig. 23 illustrates an alternative embodiment of an insert blank 303 for us in forming an insert 305 placed in the carton 5. Accordingly, like or similar features may be indicated by like or similar reference numbers from the previous embodiments. The embodiment of Fig. 23 is similar to the embodiment of Fig. 20 in that the reinforcing side flap 331 includes a tab 384 for being received in the handle opening 386 when the reinforcing side flap 331 is folded over the central panel, rn the embodiment of Fig. 23, the length of the reinforcing side flap 331 is less than the length of the central panel 306 of the insert blank 303. The insert blank 303 of Fig. 26 may be otherwise shaped, arranged, and configured without departing from this disclosure.

[0049] The blanks according to the present disclosure can be, for example, formed from coated paperboard and similar materials. For example, the interior and/or exterior sides of the blanks 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 blanks may then be coated with a varnish to protect any information printed on the blank. 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, 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] The foregoing description of the disclosure illustrates and describes various embodiments.
