The oblique fold lines 72-75 could be otherwise shaped, arranged, and/or configured without departing from the disclosure.
In the illustrated embodiment, the features that form the two handles 11, 13 are substantially similar, but only one of the handles 11 is described in detail herein. As shown in FIG. 2, the handle 11 includes an elongate handle flap 131 formed in the top end flap 12 and foldably attached to the top panel at fold line 133. In the illustrated embodiment, the handle flap 131 includes two longitudinal fold lines 135, 137 that extend across the length of the handle panel. The fold line 133 extends between respective ends of a tear line 140 that at least partially defines the handle flap 131 in the top panel end flap 12. The fold lines 135, 137 respectively extend between the tear line 140 of the elongated handle flap 131. As shown in FIG. 2, the fold lines 133, 135, 137 divide the handle panel into portions or strips 132, 134, 136 that are respectively foldably connected. The handle flap 131 includes two curved fold lines 141, 143 extending generally laterally between the fold line 137 and a portion of the tear line 141 opposite the fold line. The curved fold lines 141, 143 define two end portions 142, 144 of the handle flap 131 and a central portion 146 of the handle panel. The two end portion 142, 144 of the handle flap 131 are foldably connected to the central portion 146 to facilitate forming the handle 11 when the handle panel is pushed inward. The curved fold lines 141, 143 could be otherwise shaped, arranged, and/or omitted without departing from the disclosure. Tear line 140 extends beyond fold line 133 and into elongated panel 132 terminating at fold line 135.
As shown in FIGS. 3 and 4, the features of the handles 11, 13 include respective curved cutouts 162, 164 in the side end flaps 22, 42 to allow the elongate handle panels 131, 133 to fold inwardly when the handle is activated to form handle openings 170 (FIG. 7) in the carton 5. In the illustrated embodiment, the extension panels 62, 64 are discontiguous with the features (e.g., cutout 162, 164) in a respective side end flap 22, 24 that form handle 11. As shown in FIG. 1, the side end flaps 22, 24, 42, 44 could comprise flaps foldably connected to a respective side end flap instead of cutouts 162, 164. The flaps 162, 164 are positioned for overlapping a respective handle flap 131 upon activation of a respective handle 11, 13. In the illustrated embodiment, features that form the handle 13 in the bottom end flap 14 are identical to those of handle 11 in the top end flap 12. The handle 13 could comprise other features or the handle could be omitted without departing form the disclosure.
The elongate handle flap 131 is shaped and positioned in the blank 3 so that the handle 11 is activated by pressing on the handle panel and folding the handle panel inward into the curved cutouts 162, 164 to form the handle openings 170 in the carton 5. The opening 170 is shaped for insertion of a users fingers during grasping of the carton 5. In the illustrated embodiment, when the carton 5 is closed and the handle 11 activated for grasping of the carton (FIG. 7), the handle flap 131 is folded inward along fold line 133 to be in opposing face-to-face relation with the interior surface of a respective upper portion of the side panel end flaps 22, 42. One or both of the handles 11, 13 may be otherwise shaped and located in the carton 5 without departing from the scope of this disclosure. The handle 13 may be similarly activated for grasping of the carton 5.
In accordance with the exemplary embodiment, the blank 3 can be erected into the carton 5 by folding along the fold lines 21, 31, 41, and 52 and adhering the adhesive flap 50, to the second side panel 40, to form a sleeve 181 (FIG. 3). The side adhesive panels 54, 56 can be adhered to respective side end flaps 42, 44, such that the adhesive panels form reinforced portions of the side end flaps. The blank 3 may be otherwise configured to have multiple top panels and/or multiple bottom panels without departing from the scope of this disclosure. Further, the carton 5 may be a wrap-around type carton, with the blank 3 including locking features that can include primary and secondary locking features as is known in the art. These locking features may also comprise a single locking system or a double locking system such as those disclosed in U.S. patent application Ser. Nos. 10/183,935 and 10/703,704, the entire disclosures of which are incorporated by reference herein.
In the illustrated embodiment, the first end 51 of the carton 5 is closed by respectively overlapping and adhering the side end flaps 22, 42 and the top and the bottom end flaps 12, 32. The second end of the carton 5 is closed by respectively overlapping and adhering the side end flaps 24, 44 and the top and the bottom end flaps 14, 34. Once the blank 3 is formed into the sleeve 181 and with the second end closed, the containers may be loaded in the carton 5 from the first end 51 and then the first end may be closed by overlapping and gluing the side end flaps 22, 42. Alternative loading and closing steps may be used without departing from the scope of this disclosure.
FIGS. 3-6 illustrate the closing of the first end 51 of the carton 5 according to one exemplary method. From the partially assembled position of FIG. 3, the first side flaps 22, 42 are folded inward causing the top end flap 12 to raise and the extension panels 62, 64 to fold inward at the oblique fold lines 72, 74 to partially close the first end 51 of the carton 5 (FIG. 4). The extension panels 62, 64 are in generally face-to-face contact with portions of the top end flap 12 which has been raised by the inward folding of the side and flaps 22, 42. The top end flap 12 is then folded downward at fold line 58 forcing the extension panels 62, 64 to be downwardly folded at fold lines 66, 68. In the downwardly folded position of FIG. 5, the handle flap 131 is aligned with the curved cutouts 162, 164 (FIG. 5). When lowered from the position of FIG. 4, the top end flap 12 contacts the extension panels 62, 64 of the first side panels 22, 42 to fold the extension panels 62, 64 downward along the respective lateral fold lines 66, 68 so that the extension panels 62, 64 overlap a respective upper portion of each of the main panels 26, 46 between the lateral fold lines 66, 68 and the cutouts 162, 164 (FIG. 5). The top panel 12 is then further folded downward and secured in the position shown in FIG. 5 so that the handle flap 131 is aligned with the handle cutouts 162, 164. With the top end flap 12 lowered, the bottom end flap 32 is raised (FIG. 6) to further close the end 51 of the carton 5. In one embodiment, the exterior surface of the downwardly folded extension panels 62, 64 will typically be in opposing face-to-face contact with a portion of the exterior surface of the side end flaps 22, 42. Specifically, the portion of the exterior surface of the side end flaps 22, 42 that is in face-to-face contact with the exterior surface of the downwardly folded extension panels comprises a respective upper portion of the main panels 26, 46 below the fold lines 66, 68 and above the cutouts 162, 164. In one embodiment, at the closed end 51 of the carton a portion of the interior surface of the top end flap 12 is in face-to-face contact with the interior surface of the extension panels 62, 64 and a portion of the interior surface of the top end flap is in face-to-face contact with the exterior surface of the main panels 26, 46 of the side end flaps 22. The downwardly folded extension panels 62, 64 may be secured to the main panels 26, 46 of the side end flaps 22, 42 by adhesive such as glue. Also, the extension panels 62, 64 may be respectively secured to one or both of the top end flap 12 and a respective one of the side end flaps 22, 42. Further, the bottom end flap 32 can be secured to one or more of the top end flap 12, and side end flaps 22, 42.
The side end flaps 24, 44, top end flap 14, and bottom end flap 34 at the second end 53 of the carton 5 can be positioned in a similar manner as described above to close the second end of the carton. Alternatively, the end flaps 24, 44, 14, 34 can be alternatively shaped, arranged, and/or positioned without departing from the scope of the disclosure.
The handle 11 may be used to grasp the carton 5 by pressing against the elongate handle flap 131 to create the handle opening 170 (FIG. 7) in the closed end 51 of the carton 5. The downwardly folded extension panels 62, 64 of the side end flaps 22, 42 provides an extra layer of material above the handle 11 to reinforce the carton 5 when the carton is lifted at the handle. In the area above the handle 11, the carton 5 has four layers of material (e.g., side end flaps 22, 42, extension panels 62, 64, top end flap 12, and the inwardly folded flap 131) above the handle opening 170 to increase the strength of the carton in the area of the handle. The second handle 13 is similar to the handle 11 and is for grasping at the second end (not shown) of the carton in a similar manner as the first handle. The handle 11 is shaped and positioned in the carton so that multiple fingers of a user may be placed through the handle opening 170 in the overlapped top end panel 12 and first side panels 22, 42 and the thumb of a user may be placed on the top panel 10 for grasping and lifting the carton 5 The extension panels 62, 64 increases the strength and rigidity of the carton 5 in the area above the handle 11 to prevent the carton from tearing or otherwise failing when lifted. As illustrated, the extension panels 62, 64, side end flaps 22, 42, and top end flap 12 together form a reinforced region above the handle 11 that has a thickness of three-ply's of material.
The blank 3 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 blank 3 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 3 may then be coated with a varnish to protect any information printed on the blank. The blank 3 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 3 may be constructed of paperboard of a caliper such that it is heavier and more rigid than ordinary paper. The blank 3 can also be constructed of other materials, such as cardboard, hard paper, or any other material having properties suitable for enabling the carton 5 to function at least generally as described herein. The blank 3 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 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.
