Abstract
Carton apparatus includes lid members having locking tabs received in pockets formed in triple layer sidewalls. The intermediate layer of the sidewall defines a recess for receiving the locking tab, and forms a pocket when inner and outer sidewall layers are brought into contact with the intermediate sidewall layer. The intermediate sidewall layer includes locking edges which engage locking edges on the locking tabs. The tab-receiving pockets may be either open or closed.
