DETAILED PTION OF THE EXEMPLARY EMBODIMENTS {0020] The present disclosure generally s to cartons that contain articles such as ners, bottles, cans, etc., and handle reinforcement features of such cartons. The articles can be used for containing food and beverage products, for example. The articles can be made from materials PCTIUS2012/060530 suitable in ition for packaging the particular food or beverage item, and the materials can include, but are not limited to, glass or other ble material; aluminum andfor other metals; 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 odate articles of any shape. For the the following purpose of illustration and not for the purpose of limiting the scope of the disclosure, detailed description bes beverage containers (e.g., glass beverage bottles) as disposed within the carton embodiments. In this specification, the terms “lower,” “bottom, 77 ” and “top” te orientations ined in relation to fully erected and upright cartons. [00221 Fig. l is a plan view of the exterior side 1 of a blank, generally indicated at 3, used to form a carton 5 (Fig. 9) 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. 3). In the illustrated embodiment, the containers C are bottles, but the containers could be other beverage containers (e.g., cans, etc.) without departing from the disclosure. In the illustrated embodiment, the carton 5 is sized to house twenty containers C in a single layer in a 4x5 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, 2x6, 3x6, 4x6, 3x8, 2x6x2, 3x4x2, 2x9, 3x4, etc.). 10023] The carton 5 has first and second ends 7, 9 that have a reinforced handle 10 at each respective end of the carton. In the illustrated embodiment, the carton 5 can have product protection features 111 at least somewhat similar to the product tion features shown and described in the above-noted incorporated-by-reference patent applications. onally, the carton 5 could be without t protection features, or with a differing number of product protection features, without departing from the disclosure. {0024] Turning back to Fig. 1, the blank 3 has a longitudinal axis L1 and a lateral axis L2. A bottom panel 15 is foldably connected to a first side panel 21 at a lateral fold line 23. A second side panel 17 is foldably connected to the bottom panel 15 at a l fold line 19. A top panel 25 is foldably connected to the first side panel 21 at a lateral fold line 27, and foldably connected to an attachment flap 29 at a lateral fold line 3 l.

The bottom panel 15 is ly connected to a first bottom end flap 33 and a second bottom end flap 35. The first side panel 21 is foldably connected to a first side end flap 43 and a second side end flap 45. The second side panel 17 is foldably connected to a first side end flap 37 and a second side end flap 39. The top panel 25 is foldably connected to a first top end flap 47 and a second top end flap 49. The attachment flap 29 is foldably connected to a first ment end flap 53 and a second attachment end flap 55.

PCTIUS2012/060530 When the canton 5 is erected, the end flaps 33, 37, 43, 47, 53 close the first end 7 of the , and the end flaps 35, 39, 45, 49, 55 close the second end 9 of the carton. In accordance with an ative embodiment of the present disclosure, different flap arrangements can be used for closing the ends 7, 9 ofthe carton 5.

The end flaps 33, 37, 43, 47, 53 extend along a first marginal area of the blank 3, and are foldably connected at a first longitudinal fold line 61 that extends along the length of the blank. The end flaps 35, 39, 45, 49, 55 extend along a second marginal area of the blank 3, and are ly ted at a second longitudinal fold line 63 that also extends along the length of the blank. The longitudinal fold lines 61, 63 may be, for example, substantially straight, or offset at one or more locations to t for blank thickness or for other factors.

The blank 3 has a lateral fold line 65 extending through side end flap 37, second side panel 17, and side end flap 39 so that each of these flaps and panels may be folded along the fold line 65 to have an upper portion that tapers inward ve to a lower portion. A lateral fold line 67 extends through the side end flap 43, first side panel 21, and side end flap 45 so that each of these flaps and panels may be folded along the fold line 67 to have an upper portion that tapers inward relative to a lower portion. The blank 3 includes four diamond corners 71 that comprise a first fold line 73 in a tive end flap 37, 39, 43, 45 and a second fold line 73 in a respective side panel 17, 21. The fold lines 73, 75 of the diamond corners 71 are shaped, arranged and positioned to create a corner of the carton 5 that is in a tight fit with the ner C adjacent the comer. In one embodiment, the fold lines 65, 67 allow the side panels 17, 21 and ends 7, 9 of the carton 5 to angle inward toward the interior of the carton 5. The diamond corners 71 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.

In one embodiment, the top panel 25 of the blank 3 can have a width and a length less than a respective width and length of the bottom panel 15. In the illustrated embodiment, the narrower width of the top panel 25 than the bottom panel 15 causes the side panels 17, 21 to taper so that the bottom of the side panels are spaced further apart than the top of the side panels. The tapered side panels 17, 21 allow the carton 5 to contact the containers C at both the bottom and top of the containers. The r length of the top panel 25 as compared to the bottom panel 15 causes both ends 7, 9 of the carton 5 to be shaped to contact both the top and bottom of the containers C housed in the carton to restrain the movement of the containers in the carton. The bottom panel 15 and/or top panel 25 can be otherwise shaped, arranged, and/or configured without departing from the disclosure.

For example, the bottom panel 15 and top panel 25 could have the same width, the same length, or both the same width and length without departing from the disclosure.

PCTIUS2012/060530 The blank 3 comprises features that form the reinforced handle 10 of the carton 5. In one embodiment the es include a handle flap 81 foldably connected to a respective top end flap 4?, 49 at a longitudinal fold line 83. In one embodiment, the handle flap 81 is formed by a cut 85 extending from respective ends of the fold line 83. The cut 85 has a longitudinal portion 87 that is generally parallel to the fold line 83 and spaced apart therefrom, a concave portion 89 at a respective end of each longitudinal portion 87, and a convex portion 91 extending between a respective concave n 89 and a respective end of the longitudinal fold line 89. In one embodiment, the handle flap 81 has a longitudinal fold line 93 extending across the flap and spaced apart from the longitudinal fold line 83 and a v-shaped fold line 95 extending from the longitudinal fold line 93 to the longitudinal portion 87 of the cut 85. The handle flap 81 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.

The handle features of the blank 3 further comprise a handle feature 105 in a respective end flap 43, 45 attached to a first main panel 74, 76 and the first side panel 21. The handle features of the blank 3 further comprise a handle feature 107 in a respective end flap 37, 39 attached to a second main panel 77, 79 and the second side panel 17. The handle features se a first reinforcement portion 109 of the end flap 43, 45 above or adjacent the handle feature 105 and a second reinforcement portion 113 of the end flap 37, 39 above or adjacent the handle feature 107. The handle features comprise a first handle reinforcement flap 115 foldably connected to a respective reinforcement portion 109 of the end flaps 43, 45 at an extension 27a of the fold line 27. The extension of the fold line 27a terminates at a ed notch l 17 that is between respective free edges of the first handle reinforcement flap 115 and the first rcement portion 109. Further, in one ment, the free edges of the first handle reinforcement flap 115 and the first rcement portion 109 extend from a respective longitudinal fold line by a distance D1. The reinforcement flaps 115 are separated from an adjacent end flap 47, 49 by a cut 119 that extends from the intersection of the lateral fold line 27 with the udinal fold lines 61, 63 to a respective free edge of the blank 3.

In the illustrated embodiment, the handle features of the blank further comprise a second handle reinforcement flap 121 foldably connected to a respective base portion 54, 56 of attachment end flaps 53, 55 of the attachment flap 29 at an extension 31a of the lateral fold line 31. In one embodiment, the second handle reinforcement flap 121 is sized so that a free edge of the second handle reinforcement flap 121 is spaced from the l fold line 61 by a distance D2. In the illustrated embodiment, the distance D2 is less than the distance D1 such that a notch 123 is created in the blank 3 that is between a tive end flap 53, 55 and a respective end flap 47, 49. The handle reinforcement flaps 121 are separated from an adjacent top end flaps 47, 49 of the blank 3 by a cut 124. In the illustrated embodiment, the top end flaps 47, 49 have notches 125 that are , arranged, and positioned to odate the product/article tion features 111 that can be an WO 59261 PCTIUS2012/060530 emboss/deboss area, a bumper, any other product protection feature disclosed in the above-noted incorporated-by-reference provisional patent applications, or any other product protection feature.

As shown in Figs. 2—10, one exemplary method of forming the carton 5 from the blank is shown. The attachment flap 29 is adhesively attached to a marginal n of the second side panel 17 and the attachment end flaps 53, 55 are adhesively attached to the reinforcement portion 113 of a respective end flap 37, 39. The method comprises forming the blank 3 into a generally open—ended sleeve 151 (Fig. 4) and loading the sleeve with containers C. Alternatively, the open-ended sleeve 151 can be formed about the containers C. In one embodiment, one end 7, 9 of the sleeve 151 can be closed prior to inserting the containers into the sleeve. In the rated embodiment, the closing of the end 7 is shown and described, but the opposite end 9 (Fig. 7) ofthe carton 5 is closed in a similar manner. In the rated embodiment, the reinforced handle 7 in each end 5, 7 is formed upon folding the end flaps closing a respective end of the carton 5.

As shown in Figs. 4-6, after the containers C are loaded, the end flaps 33, 37, 43, 47 can be at least partially overlapped to close the end 7 of the carton 5 and form the reinforced handle 10. As shown in Fig. 5, the end flap 43 is first folded about the fold line 61 to partially close the end 7 ofthe carton 5. As shown in Fig. 6, the end flap 37, with attached end flap 53 of adhesive panel 29, is folded about fold line 61 to lly overlap the end flap 43. The reinforcement portion 113 of the end flap 37 partially overlaps the reinforcement portion 109 of the end flap 43. Also, the reinforcement flap 21 partially overlaps the reinforcement flap 115. In the illustrated embodiment, the top edge 155 of the reinforcement portion 113 of the end flap 37 is adjacent the v-shaped notch 1 17 between reinforcement flap 115 and the reinforcement portion 109 of the end flap 43. From the position of Fig. 6, the top end flap 47 is downwardly folded in the direction of arrow A1 with the reinforcement flaps 115, 121 being downwardly folded by t with the top end flap 47. The reinforcement flap 121 is downwardly folded to be in face-to-face t with the rcement portion 113 of the end flap 37. The reinforcement flap 115 is rdly folded and is in face-to- face contact with a portion of the reinforcement flap 121, a portion of the reinforcement n 113 ofthe end flap 37, and a portion ofthe reinforcement portion 109 ofthe end flap 43. 10035] Fig. 11 shows a cut—away portion of the reinforced handle 10 showing the positioning of the reinforcement flaps 1 15, 121 in the downwardly folded position. When the reinforcement flaps 115, 121 are downwardly folded, the top edge 155 of the reinforcement portion 113, a n of the end flap 53, and a portion of the downwardly folded reinforcement flap 121 are positioned in the v- shaped notch 117 between the reinforcement flap 115 and the reinforcement portion 109. The features of the reinforced handle 10 could be otherwise shaped, arranged, configured, and/or positioned t departing from the disclosure.

WO 59261 PCTIUS2012/060530 Fig. 8 shows an alternative embodiment of the present disclosure including glue 161 d to the end flaps 37, 43 including the reinforcement portions 109, l 13. Glue 161 can be used to secure the reinforcement flaps 115, 121 in the downwardly folded position, or glue or other adhesive could be omitted without departing from the disclosure.

As shown in Figs. 9 and 10, the handle 10 can be activated by inwardly folding the handle flap 81 about fold line 83 to create a handle opening 165 in a respective end 7, 9 of the carton 5. The handle flap 81 is shaped by the cut line 81 of the blank so that the inwardly folded handle flap 81 does not interfere with or contact the bottles C that are adjacent a respective end 7, 9 of the carton 5.

The handle flap 8] could be otherwise shaped, arranged, and/or configured without ing from the sure. The reinforcement flaps 115, 121, reinforcement portions 109, 113, end flaps 53, 55, and the attachment panel 29 ate to form a reinforcement band of the carton 5 that s around the perimeter of the top of the carton. In the ends 7, 9 the reinforcement band forms the reinforced handles 10 with reinforcement band being above the handle openings 165. In this way, the carton 5 is reinforced and deformation or tearing at the handles 10 is prevented.

As described above, the handle 10 is reinforced by several layers or plies of al. For example, the handle 10 may be reinforced by a plurality of layers of paperboard directly above the handle opening at least partially formed by the ating notches 105 and 107, top end flap 47, reinforcement flap 121, reinforcement flap 115, reinforcement portion 109, reinforcement portion 1 13, attachment end flap 53, and/or handle flap 81. For example, according to one embodiment, the reinforcement flap 1 15, the first reinforcement portion 109, and the second reinforcement portion 1 13 form three plies of material located above the handle 10 to reinforce the handle 10. According to another embodiment, the attachment end flap 53, the second reinforcement portion 113, the first reinforcement portion 109, the first reinforcement flap 115, and the second reinforcement flap 121 comprise five plies of material located above the handle 10 to reinforce the handle 10.

Figs. l2-16 illustrate a blank 203 for forming a carton 205 having a reinforced handle 210 according to a second embodiment of the sure. The blank 203 has similar features as the blank 3 of the first embodiment and like or similar reference number are used to ted like or similar features between the first and second ments. In the second embodiment, each of the reinforcement flaps l 15, 121 are approximately the same length so that the reinforcement flaps do not overlap in the carton 205 formed from the blank 203. Also, the bottom end flaps 33, 35 have been extended to have a longer length so that the free edge of the bottom end flaps are farther from a respective longitudinal fold line 61, 63 in the second embodiment of the disclosure.

PCTIUS2012/060530 In the embodiment of Figs. 12-16, both the reinforcement flaps 115, 121 have a length D2 extending from the longitudinal fold line 61, 63 to a respective free edge of the rcement flaps.

As with the us embodiment, the handle reinforcement portions 109, 113 of respective end flaps 43, 45 and 37, 39 have a length D1. In the embodiment of Figs. 12-16, both the reinforcement flaps 1 15, 121 have a length D2 that is less than the length D1 of the reinforcement portions 109, 113.

In one embodiment, the length D1 is at least approximately 5.2 inches (131 mm) and the length D2 is approximately 4.1 inches (104 mm) or less. In the illustrated embodiment, D2 is approximately 80 percent of D1, but D2 could be more or less than listed or shown herein without departing from the disclosure. The dimensions listed herein and/0r shown on the drawings are intended to be illustrative of certain embodiments or es of the sure and are not intended to limit the scope ofthe claims unless otherwise noted herein. {0042] In the embodiment of Figs. 12-15, the bottom panel 15 includes protection elements 211 in the form of flaps 215 foldably connected to the bottom panel. The protection ts are similar to the protection elements disclosed in US. Patent ation No. 13/419,740, filed March 14, 2012.

The protection ts 211 could be otherwise shaped, arranged, and/or configured without ing from the disclosure, or the protection elements could be omitted without ing from the disclosure.

As shown in Figs. 13—16 the carton 205 is formed from the blank 203 in a similar manner as set forth above for the first embodiment. As shown in Fig. 13-16, the reinforced handle 210 is formed in a similar manner as the reinforced handle 10 of the previous embodiment. Also, the rced handle 210 can be formed in both ends of the carton, but only one end 7 is shown in the Figures and described herein.

The blank 203 is formed into the carton 210 as shown in Fig. 13 with a partially open end 7 with the reinforcement flaps 115, 121 being in generally face-to-face contact with the upwardly folded top end flap 47. As shown in Figs. 13-16, the side end flap 43 partially overlaps the side end flap 37 so that the reinforcement portion 109 overlaps the reinforcement ponion 113. A distal portion 109a (Fig. 13) of the reinforcement portion 109 is located below the reinforcement flap 121 of the side end flap 37. As the end 7 is closed by the downward folding of the top end flap 47, the reinforcement flaps 115, 121 are downwardly folded at respective fold lines 273, 31a (Figs. 14, 15).

As shown in Fig. 16, the reinforcement flap 115 is further downwardly folded to be in face-to-face contact with the rcement portion 109 and the reinforcement flap 121 is further downwardly folded to be in face-to-face contact with the reinforcement n 1 13 and the distal portion 109a of the reinforcement portion 109. In this way, the handle 210 is reinforced by a plurality of layers of paperboard (e.g., three, four, five, or six plies of material) directly above the handle opening at least PCTIUS2012/060530 partially formed by the cooperating notches 105, 107 (top end flap 47, reinforcement flap 121, distal portion 109a of the reinforcement portion 109, reinforcement portion 1 13, and handle flap 81). As with the previous embodiment, glue or other adhesive can be placed between the reinforcement portions 109, 113 and the reinforcement flaps 115, 121, or at other ons of the flap arrangement.

As with the previous embodiment, the end 7 can be closed by other flap positioning ces and the handle 210 can be formed by other flap positioning sequences without departing from the disclosure. The ment of Figs. 12-16 allows the reinforcement flap (e.g., 121) attached to an opposite side end flap (e.g., 37) to overlap and/or be secured to the reinforcement portion (e.g., 109) of an opposite side end flap (e.g., 43) so that the handle 210 is strengthened and rced. The handle 210 could be reinforced by ate positioning of the reinforcement flaps 1 15, 121 and reinforcement portions 109, 113 without departing from the disclosure. For example, the reinforcement portion 113 could overlap the reinforcement portion 109 and the handle reinforcement flap 115 foldably connected to the side end flap 43 could be positioned to overlap a distal n of the reinforcement portion 113 of the side end flap 37.

The cartons 5 of any of the illustrated or non-illustrated embodiments of the disclosure could have other features (e.g., dispenser features, handle features, reinforcement features, etc.) without departing from the disclosure. Also, the cartons 5 could be otherwise shaped, arranged, or configured and the cartons could be configured to hold articles other than beverage containers C without departing from the disclosure.

In general, the blank may be constructed from paperboard having a caliper so that it is heavier and more rigid than ordinary paper. The blank can also be constructed of other als, 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 d line of ss, and/or a series of spaced apart slits that extend partially into and/or tely through the material along the desired line of weakness, or various ations of these features. As a more specific e, one type tear line is in the form ofa series of spaced apart slits that extend completely through the material, with nt slits being spaced apart slightly so that a nick (e.g., a small at bridging-like piece of the material) is defined n 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 t departing from the present disclosure.
