Abstract
An interlocking arrangement for panels comprises first and second panels, a locking tab extending from the first panel, an alignment tongue extending from the distal edge of the locking tab, a second panel, a locking slit defined in the second panel for receiving the locking tab, and an alignment slit defined also in the second panel for receiving the tongue when the locking tab is received in the locking slit. The locking tab has a head defining a widened locking shoulder disposed along at least one of its side edges. The shoulder of the locking tab is designed to engage the locking slit to retain the locking tab within the locking slit. The locking slit is disposed alongside the leading edge of the second panel. The alignment slit is disposed adjacent to the locking slit such that the locking slit is interposed between the alignment slit and the leading edge of the second panel.
