<p>A carton includes first (12) and second (20) overlapping panels and a lock for securing the panels to each other. The lock includes a locking tab (60, 62, 64, 66) struck from the first panel and a retaining tab (70, 72, 74, 76) struck from the second panel and defining a locking aperture (102) in the second panel. The locking tab is foldably joined at its proximal end edge to the first panel and extends to its free end edge opposed to the proximal end edge. The locking aperture has one end edge extending along the proximal end edge of the locking tab and the other end edge opposed to the one end edge. The retaining tab is foldably joined at its proximal end edge to the other end edge of the locking aperture and extends to its free end edge opposed to the proximal end edge of the retaining tab. The locking tab is folded in an angular relationship with the first panel such that the locking tab is received in the locking aperture. The retaining tab is folded in an angular relationship with the second panel such that the retaining tab is in abutment at its free end edge on one of the opposite sides of the locking tab whereby the locking tab is held in the locking aperture. The locking tab has a tongue (84) projecting from the free end edge of the locking tab while the retaining tab is provided with a notch (100) or aperture (120) for receiving the tongue of the locking tab.</p> |
