Abstract
A self-locking, reusable carton is formed from a unitary blank of paperboard. The carton and blank have self-locking end closure flaps which are hingedly coupled to adjacent end edges of the side panels of the carton. The closure flaps include two flaps with L-shaped slits formed therein and a locking flap free of fold lines with a locking tab at the free end thereof. During assembly the locking flap is forced downwardly to place the locking tab in the L-shaped slits to lock the carton in its fully assembled configuration.
