Abstract
Abstract A carton, and a blank therefor, including a wraparound corner locking flap construction comprising a T-shaped first element joined to part of the carton and two other elements joined to another part of the carton. Reclosure after the initial opening of the carton is obtained by engagement of the T-shaped element with the other locking elements. The construction of the wraparound corner locking flap is of a particular configuration which will give especially effective reclosure of a carton having a wall panel with a corner portion which can be articulated about a diagonal fold line formed in such wall panel.
