• the side panels 123, 129 and the end walls 191a, 191b can cooperate to at least partially form a sidewall 192 extending around the interior 189 of the tray 107.
• the tray 107 could be formed by other forming steps without departing from the disclosure.
• the lid 111 can be formed by folding the top closure panel 163 and the top end panels 173, 175 relative to the top panel 161 along the respective fold lines 165, 175.
• the locking tab 167 separates from the top closure panel 163 along the cut line 167 so that the tab 167 extends outwardly from the top panel 161 adjacent the top closure panel 163.
• the carton 103 is shown in an open configuration in Figs. 2A and 2B with the lid 111 folded away from the tray 107 so that items can be loaded into and/or removed from the interior 189 of the tray 107.
• the carton 103 can be moved to a closed configuration (Figs. 3A-6) by folding the lid 111 toward the tray 107 at the hinge 115.

• the hinge panel 181 can be folded into face-to-face contact with an interior surface of the first side panel 123.
• the lid 111 can be moved into the interior 189 of the tray 107 so that the top panel 161 is spaced downwardly from the lateral fold lines 183, 153 and the upper edges 193 of the end flaps 139, 141, 145, 147.
• the locking tab 167 can engage (e.g., can be at least partially received in) the locking opening 155 in the bottom closure flap 151 to help lock the lid 111 in the closed position with the tray 107. As shown in Fig.
• the locking opening 155 in the bottom closure flap 151 can be located along the interior of the second side panel 129 (e.g., so that the opening is not in an exterior surface of the tray 107, which can help prevent the contents of the carton 103 from spilling out and/or contaminants from entering the carton 103 via the locking features and/or can hide the locking features from the exterior of the carton 103). Further, as shown in Fig.
• the second side panel 129, the bottom closure flap 151, and the top closure panel 163 can be overlapped and/or in proximity (e.g., with the bottom closure flap 151 sandwiched between the second side panel 129 and the top closure panel 163), and the locking tab 167 can extend outwardly from the top panel 161 into the locking opening 155 in the bottom closure flap 151.
• the locking tab 167 can extend toward and/or abut the interior surface of the second side panel 129.
• the lid 111 could be otherwise closed without departing from the disclosure.
• an upper support feature of the carton 103 can be formed when the carton 103 is in the closed configuration. For example, as shown in Figs.
• the lateral fold lines 183, 153 and the upper edges 193 of the end flaps 139, 141, 145, 147 can cooperate to form a support edge 195 of the carton 103 (e.g., along the sidewall 192 of the tray 107).
• the support edge 195 can contact and support the bottom panel 121 of an upper carton 103 stacked on top ofthe lower carton 103 (Fig. 6).
• the top panel 161 can be smaller (e.g., in the lateral direction L2) than the bottom panel 121 so that the end walls 191a, 191b are sloped inwardly from their bottoms to their tops (e.g., Fig. 4) and so that the upper edges 193 ofthe end panels 191a, 191b are spaced inwardly from the outermost edges of the bottom panel 121 (e.g., along the longitudinal fold lines 138).
• the carton 103 can include two end cutbacks, recesses, or passageways 197 at least partially defined in the end walls 191a, 191b.
• the passageways 197 can be at least partially defined along the distal edge 199 of the bottom end panel 135 between the end flaps 139, 145 and along the distal edge 199 of the bottom end panel 137 between the end flaps 141, 147.
• the passageways 197 can facilitate moving air (e.g., cool, dry air in a refrigerator) over the top panel 161 of a lower carton 103 even when an upper carton 103 is stacked on the lower carton.
• air e.g., cool, dry air in a refrigerator

Accordingly, the moving air can help remove moisture (e.g., by evaporation, entraining the moisture in the air, etc.) that might otherwise accumulate between the stacked containers. While two cartons 103 are shown in the stack 200 in Fig.
• any suitable number of cartons 103 can be arranged in the stack 200, such as in a display case for sale, in a storage facility, in transportation, etc.
• a plurality of cartons 103 with more than two cartons 103 could be stacked.
• the film 179 (e.g., bioderived cellulose acetate) can be sensitive to moisture (e.g., can be adversely affected by moisture).
• moisture can contribute to warping, rippling, deformation, etching, clouding, and/or other damage of the film 179, which may look bad to potential customers and/or can make it difficult for potential customers to see the items in the interior of the container 103.
• removing any moisture that may be present between stacked cartons 103 can help avoid damaging the film 179 and can help keep the film 179 at least partially transparent.

• the blank may also be coated with, for example, a moisture barrier layer, on either or both sides of the blank.
• the blank may be constructed of paperboard of a caliper such that it is heavier and more rigid than ordinary paper.
• the blank 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 blank can also be laminated or coated with one or more sheet-like materials at selected panels or panel sections.
• 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 or depressed 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. In situations where cutting is used to create a fold line, typically the cutting will not be overly extensive in a manner that might cause a reasonable user to incorrectly consider the fold line to be a tear line.
• 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.
• one type of 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.
• 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.
• glue is intended to encompass all manner of adhesives used to secure carton panels in place.
