The dispenser features include a tear line 105 in the front panel 15 that comprises two oblique portions 107 extending from the ends of fold line 19 and a lateral portion 109 connecting the oblique portions. The tear lines 101, 103, 105 define a dispenser panel 111 that includes the first top panel 17, a portion 113 of the front panel 15 defined by the tear line 105, and the second top panel 29 that is adhered to the first top panel 17 in the carton 5 formed from the blank 3. The blank 3 and/or carton 5 could have dispenser features that are otherwise shaped, arranged, and/or configured without departing from the disclosure.

As shown in FIG. 1, the blank 3 includes handle features for forming the handle 11 of the carton 5. The handle features include a handle opening 121 in the back panel 25, two oblique fold lines 123, 125 each generally extending from a respective end of the lateral fold line 31, a curved fold line 127 extending between the oblique fold lines, a handle flap 129 foldably connected to the back panel 25 at the curved fold line 127 and extending from the curved fold line into the handle opening 121, and a handle reinforcement flap 131 formed by a cut 133 in the second top panel 29. In the illustrated embodiment, the handle reinforcement flap 131 is foldably connected to the second top panel 29 and the back panel 25 at the portion of the lateral fold line 31 extending between the cut 133, but the handle features could be otherwise shaped, arranged, and/or configured. The blank 3 and/or carton 5 could have handle features that are otherwise shaped, arranged, and/or configured without departing from the disclosure.

In one exemplary embodiment, the carton 5 is formed from the blank 3 by positioning the panels 15, 17, 21, 25, 29 relative to each other and by folding along respective fold lines 19, 23, 27, 31 to form a bottom, front, back, and top of the carton. The second top panel 29 is folded inwardly so that the first top panel 17 overlaps and is adhered to the second top panel 29. The sides 91, 93 are closed by overlapping and adhering the end flaps 51, 55, 59, 67 at the first side 91 and the end flaps 53, 57, 61, 69 at the second side 93. At each side 91, 93, the end flaps 67, 69 connected to the back panel 25 are folded inwardly first and are overlapped by the end flaps 51, 53 connected to the front panel 15 and the end flaps 55, 57 connected to the first top panel 17 in succession. Prior to closing one or both sides 91, 93 of the carton, the article support flaps 75, 77 are formed in the interior 141 by folding the article support flaps along fold lines 79, 81 and positioning the support flaps generally face-to-face contact or approximate the end flaps 67, 69. The rounded corners 41, 43 are formed by positioning the edge margins of the front panel 15 that include the fold lines 33 in a curved configuration so that each of the edge margins of the front panel conforms to the shape of the curved edges 35, 37, 39 of the first top panel 17, bottom panel 21, and second top panel 29. Prior to closing the top of the carton 5, containers C are placed in the carton with at least a portion of the two front containers (i.e., the containers adjacent the front panel 15) being in secure supporting contact with the rounded corners 41, 43 and at least a portion of the two back containers (i.e., the containers adjacent the back panel 25) being in secure supporting contact with the article support flaps 75, 77. The carton 5 can be formed and/or loaded with containers in alternative methods that can include different or alternative steps without departing from the disclosure.

In one embodiment, the handle 11 can be formed prior to closing one or both sides 91, 93 by downwardly folding the handle reinforcement flap 131 and adhering the handle reinforcement flap to the back panel 25 just above the handle flap 129. The handle reinforcement flap 131 may be secured to the back panel 25 prior to the second top panel 29 being secured to the first top panel 17. The handle reinforcement flap 131 has a curved edge 151 that overlaps and conforms to the curved fold line 127 in the back panel 25. When the handle 11 is grasped, the handle flap 129 can be upwardly folded along fold line 127 and can be positioned in face-to-face contact with the handle reinforcement flap 131 in the interior 141 of the carton 5 so that the carton 5 includes three layers of material above the handle opening 121 (e.g., the upwardly folded handle flap 129, the handle reinforcement flap 131, and the portion of the back panel 25 above the handle opening 121). In this way, the handle 11 is reinforced and strengthened to prevent tearing of the carton 5 upon grasping and lifting at the handle. The handle 11 could be formed by other methods or forming steps without departing from the disclosure.

The dispenser 10 can be activated to access the containers C by tearing along tear lines 101, 103, 105 to at least partially separate the dispenser panel 111 from the remainder of the carton 5. As shown in FIGS. 4-6, the dispenser panel 111 can be lifted and pivoted about fold line 31 to create a dispenser opening 155 in the top of the carton 5. One or more of the containers C can be removed from the carton 5 through the dispenser opening 155. The dispenser 10 and dispenser panel 111 could be otherwise shaped, arranged, and/or configured without departing from the disclosure. In an alternative embodiment, the dispenser panel 111 could be removed from the carton without departing from the disclosure. Also, the dispenser panel 111 and/or the dispenser 10 could be alternatively shaped to allow access to the containers C through other than the top of the carton 5 without departing from the disclosure.

The carton 5 is configured to provide secured packaging of the four containers C in the interior 141 by the configuration of the rounded corners 41, 43 and the article support flaps 75, 77 in the interior 141 of the carton. In this way, all four containers C are held in a tight engagement to reduce movement of the containers and possible breakage. The carton 5 could have other features to prevent breakage of the containers without departing from the disclosure. Further, the handle 11 is reinforced and located in the back panel 25 to allow the carton 5 to be easily carried without tearing during lifting of the carton. The dispenser 10 is configured to allow quick and convenient access to the containers C through the top of the carton 5 without compromising the integrity of the handle 11. Also, the opened carton 5 can continue to be carried at the handle 11 after removing one or more of the containers though the dispenser 10.

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.

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.
