For use primarily in article carriers, interlocking structure for securing a pair of face contacting overlapping panels in interlocked relation includes a locking aperture formed in one of the panels and having an anchoring edge and a spaced securing edge disposed in generally parallel relation and including side edges together with a locking tab having a body portion, a heel portion, and a toe portion and being struck from the other of said panels and folded through an angle of approximately 180.degree. toward an adjacent edge thereof and into face contacting relation with the part of the other panel which is disposed adjacent the edge thereof and so as to cause the heel portion to enter the locking aperture and to engage the anchoring edge and to cause the toe portion to enter the locking aperture adjacent the securing edge.
Interlocking structure for a pair of overlapping panels comprising a locking aperture formed in one of said panels and having an anchoring edge and a securing edge spaced from said anchoring edge and generally parallel thereto, and a locking tab having a body portion, a heel portion, and a toe portion and being struck from the other of said panels near an edge thereof and folded through an angle of approximately 180.degree. and into face contacting relation with the part of said other panel which is disposed adjacent said edge thereof and so as to cause said heel portion to enter said locking aperture and to engage said anchoring edge and to cause said toe portion to enter said locking aperture adjacent said securing edge so that when the lock is formed the body portion of the locking tab is disposed in enveloping face contacting relation with the edge portion of the panel from which the locking tab is struck.
A generally rectangular blank for a wrap around type article carrier having a lap panel at each end and comprising at least one locking aperture formed in one of said lap panels and including generally parallel spaced anchoring and securing edges arranged in generally parallel relation to the end edge of said one lap panel, at least one locking tab struck from the other of said lap panels and including a body portion foldably joined thereto by a pair of aligned fold lines and projecting inwardly from the end edge of said other lap panel, a heel portion formed integrally with said body portion and projecting outwardly toward the end edge of said other lap panel, and a toe portion foldably joined to said body portion and projecting inwardly from the end edge of said other lap panel.
