Abstract
A carton having interfitting cover and bottom portions is formed from an integral blank and has improved automatic locking features. Locking tabs struck out from an endwall of the cover are received in recesses formed in an endwall of the bottom portion. The locking tabs are wedged by folded end flaps to insure proper orientation for reception in the recesses, and to provide a bias force to urge the locking tabs into engagement with wall portions surrounding the recesses.
