(35) With reference to FIGS. 4 and 5, as embodied herein, container 400 can be formed from blank 300 by folding first side flap 318b and second side flap 318d inwardly along first side flap fold line 320b and second side flap fold line 320d, respectively, and folding first side flap 318a and second side flap 318c inwardly along first side flap fold line 320a and second side flap 320c, respectively. In this manner, as shown for example in FIG. 5, first side flap 318a can at least partially overlap first side flap 318b, and second side flap 318c can at least partially overlap second side flap 318d. Additionally, and as embodied herein, first side flap 318a can be joined to second side flap 318c proximate first side flap fold line 320a and second side flap fold line 320c. Furthermore, and as embodied herein, first side flap 318b can be joined to second side flap 318d proximate first side flap fold line 320b and second side flap fold line 320d, with areas 340a and 340b free of adhesive to form opening 340 (shown in FIG. 6).

(36) In this configuration, the joined pairs of flaps can move inwardly independently of each other from an initial flat configuration into the expanded configuration with the first and second body portions 310, 314 in a contoured condition, as shown for example in FIGS. 6 and 7. With reference to FIGS. 6 and 7, in the contoured configuration, contoured upper edges of first side flaps 318a, 318b and contoured upper edges 328a, 328b of second side flaps 318c, 318d can define a contoured upper edge of the interior dividing wall 410, which can facilitate access to compartments 412, 414 in the interior of the container.

(37) In addition, and as embodied herein, at least one of the first and second body portions 310, 314 can have a foldable support formed therein to hold a receptacle, as shown and described for example in U.S. Pat. No. 8,584,884, which is incorporated by reference herein in its entirety.

(38) Reference is made now to another alternative embodiment of a unitary blank 500 for a container shown in FIGS. 8-10, in conjunction with container 600 of FIGS. 11 and 12 formed by the blank 500 of FIGS. 8-10. The unitary blank 500 and container 600 can include some or all of the various features described herein with respect to unitary blank 100 and container 200 and/or blank 300 and container 400.

(39) As shown in FIGS. 8-10, the blank 500 generally includes a first body portion 510 and a second body portion 514 aligned along a longitudinal axis. The first body portion 510 and the second body portion 514 each have a base edge 512a, 512b and opposing sides 516a, 516b, 516c, 516d. The base edge 512a of the first body portion 510 face the base edge 512b of the second body portion 514. The blank 500 further includes first side flaps 518a, 518b extending laterally from the opposing sides 516a, 516b of the first body portion. Each first side flap 518a, 518b is defined in part by a first side flap fold line 520a, 520b along at least a portion of a respective side of the first body portion 510. As shown in FIGS. 11 and 12, and as discussed further below, the first side flaps 518a, 518b form an interior dividing wall 610 when the first and second body portions 510, 514 are joined proximate the opposing sides 516a, 516b, 516c, 516d thereof to define container 600 having an interior. With reference to FIGS. 11 and 12, the interior dividing wall 610 can define a portion of and at least partially separate compartments 612, 614 in the interior of the container 600.

(40) As embodied herein, at least one of the first body portion 510 and the second body portion 514 can have an arcuate first upper edge 536a defining a portion of the mouth and extending toward the interior of the container. The other of the first body portion 510 and the second body portion 514 can have an arcuate second upper edge 536b defining a portion of the mouth and extending away from the interior of the container. Additionally or alternatively, at least one of the first body portion 510 and the second body portion 514 can have bend lines 538 extending along at least a portion of a length thereof to provide the contoured condition of the at least one of the first body portion 510 and the second body portion 514.

(41) Furthermore, and as embodied herein, blank 500 can have one or more engagement features to form container 600 with inner dividing wall 610. For example, with reference to FIG. 8, blank 500 can have an engagement feature in the form of a raised surface disposed within an aperture, as described below. For example, and as embodied herein, one of the first side flaps 568b and one of the second side flaps 568d each can have an aperture 570a, 570b defined therein. Aperture 570a of the first side flap 568b and aperture 570b of the second side flap 568d each can be spaced apart a similar distance from a corresponding base edge 572a, 572b and aligned with each other. The other of the first side flaps 568a and the other of the second side flaps 568c can be secured together at a discrete location 574a, 574b, which can be disposed within the aperture 570a of the first side flap 568b and the aperture 570b of the second side flap 568d. Each second side flap 568c, 568d can have at least one contoured upper edge 528a, 528b extending from the second body portion 514.

(42) Additionally, and as embodied herein, the discrete location 574a, 574b of each of the other of the first side flaps 568a and the other of the second side flaps 568c can include a raised surface 580a, 580b. The other of the first side flaps 568a and the other of the second side flaps 568c can be secured together by an adhesive applied to the raised surfaces 580a, 580b at the discrete location 574a, 574b. For example, and as embodied herein, first side flap 568a and second side flap 568c can be folded inwardly, and first side flap 568b and second side flap 568d can be folded inwardly. In this manner, first side flap 568b can at least partially overlap first side flap 568a, and second side flap 568d can at least partially overlap second side flap 568c. Furthermore, and as embodied herein, in this configuration, raised surfaces 580a, 580b of discrete locations 574a, 574b of first side flap 568a and second side flap 568c, respectively, can be exposed through apertures 570a, 570b in overlapping first side flap 568b and second side flap 568d. Adhesive can be applied to the raised surfaces 580a, 580b, and the corresponding first side flap 568a and second side flap 568c can be joined and adhesively secured together proximate the raised surfaces 580, 580b.

(43) The joined first side flap 568a and second side flap 568c can move, for example and without limitation, within apertures 570a, 570b of the joined first side flap 568b and second side flap 568d from an initial flat configuration into the expanded configuration with corresponding body panels in a contoured condition. That is, as shown for example and without limitation in FIGS. 11 and 12, the secured raised surfaces 580a, 580b at the discrete location 574a, 574b can be disposed at one region 576a, 576b of the aperture 570a, 570b when container 600 is in the flat configuration. The secured raised surfaces 580a, 580b at the discrete location 574a, 574b can move toward another region 578a, 578b of the aperture 570a, 570b when container 600 is urged toward the expanded configuration. When container 600 is in the expanded configuration, the secured raised surfaces 580a, 580b can engage the first and second side flaps 568b, 568d proximate the another region 578a, 578b of the aperture 570a, 570b. With reference to FIGS. 11 and 12, in the contoured configuration, contoured upper edges 528a, 528b of second side flaps 568c, 568d can define a contoured upper edge of the interior dividing wall 610, which can facilitate access to compartments 612, 614 in the interior of the container.

(44) Additionally, and as set forth above, engagement features can be provided in the form of hooks. For example, and as embodied herein, each first side flap 568a, 568b can have opposing hooks 522a, 522b extending from the first body portion 510. With reference to FIGS. 11 and 12, the hooks 522a, 522b are disposed to engage each other when the first side flaps 568a, 568b are folded along the first side flap fold lines 520a, 520b and moved toward each other. Additionally, or alternatively, and as set forth above, engagement features can be provided in the form of tabs (not shown).
