<p>A box closure device (20) releasably engages the flaps of a box (22) in a closed configuration. The device has a lower element (28) which extends generally in a first plane. An upper element (32) is connected to the lower element and spaced substantially parallel to it by a central stem (34), such that portions of the box flaps are engaged between the upper and the lower element. A tab (36) is connected to the upper element along a living hinge (38) and is pivotable about the hinge from a first position extending substantially in the same plane as the upper element, to a second position which extends upwardly from the upper element, such that the tab may be engaged to assist in the rotation of the device when being installed in a box, and, when released, the tab returns to the first position. The lower element may be a planar disc, or may be cupped.</p> |
