The assembled handle 7, as shown, is formed by the attachment of the central handle portion 73 of the second top panel 23 to the handle portion 83 and the folded handle reinforcement flap 91 of the first top panel 29. As described above, the relief portion 50 of the end flap 49 defined by the cut 77 is adhered to the portion 84 of the handle portion 83 along the end flap 49, and the relief portion 52 of the end flap 51 defined by the cut 79 is adhered to the portion 86 of the handle portion 83 along the end flap 51. In this regard, the handle 7 includes a strap handle portion 121 having a three-ply configuration in the overlapped top panels 22, 29 formed by the central handle portion 73, the handle portion 83, and the handle reinforcement flap 91.
In this regard, in the closed ends 67, 69 the handle 7 is reinforced by the overlapped portions of the handle features. For example, the handle 7 includes portions of the overlapped end flaps 49, 53 forming a three-ply configuration formed by the relief portion 50 of end flap 49 defined by the cut 77 and the portions of handle portion 83 and reinforcing flap 91 along the end flap 53. The handle 7 has a four-ply configuration where the relief portion 50 and portions of handle portion 83 and reinforcing flap 91 are overlapped by only one of the side end flaps 41, 45 in the area adjacent respective cuts 111, 115. The handle has a five-play configuration in the closed end 67 where the marginal portions of the side end flaps are overlapped. Similarly, the closed end 69 has a four-ply configuration where the end flaps 43, 47 are not overlapped and a five-ply configuration where the end flaps 43, 47 overlap at the relief portion 129 formed in the closed end 69. Such reinforced configuration of the handle 7 allows the handle to be used on large cartons 5 such as cartons containing 24 containers without tearing or failure of the handle. The handle 7 can have other features or the features shown herein can be otherwise shaped, arranged, configured, and/or omitted without departing from the disclosure.

Additionally, the relief portion 50 defined by the cut 77 of end flap 49 and the relief portion 52 defined by the cut 79 of end flap 51 provide relief for the handle 7. Because the handle portion 83 is adhered to the relief portions 50, 52 as described above, upward movement of the handle 7 causes the relief portions 50, 52 to flex inwardly toward the interior 92 of the carton 5. Such inward flexion of the portions 50, 52 serves to reduce stresses on both the handle 7 and the ends 67, 69 of the carton 5 to reduce the possibility of tearing. Additionally, such inward flexion of the relief portions 50, 52 serves to provide the handle 7 with an enhanced degree of movement relative to the remainder of carton 5, for example, such that the carton 5 can be jostled or subjected to incidental movement without causing undue stress or strain on either the handle 7 or the hand of a user carrying carton 5. Because the relief portions 125, 129 of the respective ends 67, 69 of the carton 5 formed by respective cuts 111, 115 and 113, 117 are secured to the respective relief portions 50, 52, it will be understood that relief portions 125, 129 may also flex inwardly toward the interior 92 of the carton 5 upon movement of the handle 7 to provide relief as described above.
In one embodiment, the features of the blank 3 that form the handle 7 include a first handle portion 83, a second handle portion 73, a third handle portion comprising the overlapped cuts 77, 111, 115 and relief portion 50 that is overlapped by portions of the side end flaps 41, 45 in the closed end 67 of the carton, and a fourth handle portion comprising the overlapped cuts 79, 113, 117 and relief portion 52 that is overlapped by portions of the side end flaps 43, 47 adjacent the cuts 113, 117 to form the relief portion 129, in the closed end 69 of the carton. The second handle portion 73 is spaced apart from the third handle portion and the fourth handle portion and the first handle portion 83 is connected to the second handle portion 73, the third handle portion, and the fourth handle portion to provide strength and reinforcement of the handle 7.
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 handle features and stress-relief areas of the various embodiments can be incorporated into a carton 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 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 blanks. The blanks may also be coated with, for example, a moisture barrier layer, on either or both sides of the blanks.
In accordance with the exemplary 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 package to function at least generally as described above. The blanks 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 more panels adhered together by glue. The term “glue” is intended to encompass all manner of adhesives commonly used to secure carton panels or flaps in place.
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 there along. 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 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.
