ABSTRACT:
Open-faced cartons of the corrugated paper type and corner holders therefor having stacking lugs for cooperating with the apertured bottom of another like carton to preclude lateral movement between a pair of cartons when one is stacked on the other are disclosed. In one preferred form, each corner holder comprises inner and outer sidewall engaging flanges interconnected by a "U" shaped portion to be disposed in a carton sidewall slot with a lug in the form of a relatively flat blade and a pair of reinforcing gussets extending upwardly into the bottom of a superadjacent tray. Two such carton sidewall slot engaging clasps interconnected by a generally flat rib may be employed at each corner around an open carton face to hold the carton material in its folded position, provide a support surface for a superadjacent tray and to prevent lateral movement of that superadjacent tray on the support surface. Column joining tie sheets especially suited to use with such cartons and corner holders are also disclosed.
