Packing plate cartons with overlapping bottom plates and their blanks
[Abstract] A winding-type packaging board carton with a pair of overlapping bottom plates (12, 20). One of the base plates (12) having locking tabs (38) is located above the tabs (42) projecting from the end edge of the other base plate (20). The projecting tab (42) has a complementary locking hole (40) that engages the locking tab (38) to secure the overlapping base plates (12, 20) together. On either side of the locking tab (38), said one base plate (12) has a hinged flap (50, 52) projecting from the end edge of the panel. Each hinged flap is located below the end edge (44, 46) of the other base plate (20) and on both sides of the protruding tongue (42). This "up and down" arrangement presents fewer external overlapping edges than simply completely overlapping, and thus mitigates floor skew or divergence that can cause the locking device to tear and/or move.
