When the gussets 81, 101 are activated to form the gable top 8 of the carton 5, the upper portions 25a, 31a of the front panel 25 and the back panel 31 are positioned obliquely relative to the bottom portions 25b, 31b of the front and back panel so that the upper portions 25a, 31a converge, and the first top end flap 121 and the second top end flap 131 are brought into face-to-face contact to close the top of the carton.

[0029] With reference to Figs. 1, 3A, and 3B, one or both of the two locking features 9 are activated to lock the top 8 of the carton 5 and releasably secure the top end flaps 121, 131 in face-to-face contact in the closed configuration by folding the first locking tab 135 to overlap the first top end flap 121 and inserting the locking tab 135 into the locking opening 125 in the front panel. The second locking tab 137 is folded to overlap the first top end flap 121 and inserted into the locking opening 127 to lock the carton 5 in the closed configuration. In one embodiment, each locking tab 135, 137 has a locking portion 135a, 137a shaped for insertion into a respective locking opening 125, 127. The top 8 of the carton 5 can have locking features 9 that are otherwise shaped, arranged, configured, and/or positioned without departing from the disclosure. In this regard, locking tabs 135, 137 form male locking features and locking openings 125, 127 form female locking features for the carton 5. [0030] In one embodiment, the interior 152 of the carton 5 can be accessed by removing the locking tabs 135, 137 from a respective locking opening 125, 127 so that the top of the carton 5 can be positioned in an open configuration allowing access to articles held in the carton. The carton 5 can be reclosed by reinserting the locking tabs 135, 137 into a respective locking opening 125, 127.

[0031] The carton 5 could include various handle features for carrying the carton and could include various dispenser features for opening the carton. Further, the carton 5 could include other panel/flap closing configurations without departing from the disclosure.

[0032] 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.

[0033] 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.

[0034] 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 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.
