1. A zipper carton comprising:
a first panel having an elongated slot extending therethrough, the slot includes a first end opposite a second end and a tab that projects into the slot, the slot defines a length extending between the first and second ends, and the slot defines a first slot width at the tab, a second slot width between the first end and the tab, and a third slot width between the second end and the tab, the first slot width is narrower than the second slot width and the third slot width; and
a locking panel assembly comprising:
a removable zipper tear strip; and
a locking tab having a linear length that is greater than the length of the slot, the locking tab comprising:
a base having a front edge, an opposing back edge, and a first side edge and a second side edge that both extend between the front edge and the back edge, the base projecting from the removable zipper tear strip;
a first retention flap projecting from the first side edge of the base and being foldable relative to the base;
a second retention flap projecting from the second side edge of the base and being foldable relative to the base; and
a third retention flap projecting from the front edge of the base and being foldable relative to the base,
wherein the locking tab is configured such that, in response to folding the first retention flap, the second retention flap, and the third retention flap from a relaxed position to a folded position, at least a portion of the locking tab including the first retention flap, the second retention flap, and the third retention flap is configured to slide through the slot and, after the first retention flap, the second retention flap, and the third retention flap pass through the slot, the first retention flap, the second retention flap, and the third retention flap automatically resiliently rebound at least partially toward the relaxed position so as to block retraction of the locking tab from the slot, and
wherein the first retention flap and a portion of the third retention flap are configured to slide through the slot between the first end and the tab, the second retention flap and a portion of the third retention flap are configured to slide through the slot between the second end and the tab, and a portion of the third retention flap is configured to slide through the portion of the slot at the tab.
