ABSTRACT:
A paperboard carton and blanks therefor formed from a top unit and a bottom unit which are relatively slidable. A locking mechanism prevents the units from being fully separated. This locking mechanism comprises a locking flap hingedly coupled to and folded against a side wall on either of the top and bottom units and a corresponding stop member formed on an opposed side wall of the other of the top and bottom units. The stop member is comprised of two side glue flaps extending integrally from two adjacent side walls, each having a tab extending therefrom. The tabs engage the distal end of the folded locking flap to prevent full separation. Advantageously, the locking flap is trapezoidal and the side glue flaps form a trapezoidal recess with the tabs forming the smaller base thereof. An air freshener material or insect poison can be located inside the carton.
