Abstract Carton assembly for sausage casings and the like formed of two rectangular boxes assembled to provide a closed receptacle consisting of a top box having a bottom box telescoping therefrom. The two boxes are formed of blanks respectively folded into locking or semilocking positions. Locking of the top box is through end tabs folded into the box interior. The bottom box is locked or semilocked by means of a positioning of locking tab flaps in slots on cooperatively engaging flaps of the bottom box blank. The top box can be provided with an openable side flap whereby the carton assembly has an easy open end or side.
