ABSTRACT:
A top-loading carton of paperboard or the like is constructed from a one-piece blank and enclosed by gussetted top panels. The top panels end in handles which define locking tabs which are received in slots in the side walls of the carton. The gusset panels urge the locking tabs into locking engagement with the slots. The end walls and top panels attached thereto taper outwardly from bottom to top of the carton, causing the side walls to bow outwardly when the top panels are closed, enhancing the appearance of the carton. The carton can be initially assembled into a collapsed flattened form from which it can be easily erected. An automatic bottom closure is provided.
