Abstract
A locking arrangement for panels includes a first panel, a locking tab extending from the first panel, a second panel having a main portion, and a leading portion connected thereto along a plurality of collinear panel fold lines, and a pair of locking slits defined in the second panel. Each locking slit extends at least from a first point disposed astride one of the panel fold lines, into the leading portion and to a second point disposed on the main portion, and the locking slits defining therebetween a strut panel. The locking tab is received into the slits, and is held between the strut panel and the second panel. A strut fold line may be disposed across the strut panel from the locking slit to the cut edge substantially in parallel to the panel fold line, the strut fold line being disposed in an offset relationship to the panel fold line in a direction toward the leading portion, whereby folding of the leading portion at least partially opens the locking slit for receiving the locking tab thereinto.
