The top end flap 12 with handle reinforcing flap 214 attached thereto can be downwardly folded to further at least partially close the first end 51, and the bottom end flap 32 can be upwardly folded to further close the first end 51. As shown in FIGS. 5, 8, and 9, the article retention end flaps 212 are on the inside of the carton 5 such that the lower edge 220 of the article retention end flaps contacts the interior surface of the side end flaps 22, 42. The article retention end flaps 212 are folded downward from the central panel 206 such that the article retention end flaps are generally oblique relative to the top panel 10 of the carton 5. The article retention flaps 212 contact the tops CP of the containers C located adjacent the end 51 of the carton 5 so that movement of the containers C is restrained in the carton. In one embodiment, the article protection flaps 72 in the bottom panel 30 also restrain movement of the containers C. The article retention end flaps 212 could be otherwise shaped, arranged, positioned, and/or located without departing form the disclosure. In the illustrated embodiment, the second end 53 can be closed (not shown) in a similar or identical manner as the first end 51. The first end 51 and/or the second end 53 could be closed by other steps without departing from the disclosure.
The erected carton 5 according to the exemplary embodiment is shown in FIG. 5. In the illustrated embodiment, as the upper portions 141, 143 are placed in overlapping relationship and the cutouts 140, 142 are generally aligned to form an opening to provide clearance for inwardly folding the handle flap 131 when the side end flaps 22, 42 are closed (FIGS. 5 and 8). Then the top end flap 12 and handle reinforcement end flap 214 are downwardly folded from the position of FIG. 5 so the handle reinforcement flap extends across and is in face-to-face contact with the overlapped upper portions 141, 143 to reinforce and strengthen the handle 11. Four plies of material are provided directly above the handle 11 (the overlapped upper portions 141, 143, the handle reinforcement flap 214, and the top end flap 12) prior to activation of the handle flaps 131, 132. When the handle flaps 131, 132 are inwardly folded and pushed upwardly in the direction of arrow A1 (FIG. 8), the upwardly folded handle flap 131, 132 provides a fifth layer of material that reinforces the handle 11. When the handle 11 is activated and the handle flap 131 is folded inwardly as shown in FIGS. 7 and 8, the handle forms a handle opening 304 in the top end flap 12 aligned with the cutouts 140, 142 in the side end flaps 22, 42. The handle 11 may be otherwise shaped, arranged, configured, or could have other reinforcing features without departing from the disclosure. Further, one or more of the handles could be omitted without departing from the disclosure.
