A package includes a container having an open end and a closed end and a slider slidably mounted within the container. A releasable locking feature is provided at a side of the package, which comprises locking edges associated with a sidewall of each of the slider and container respectively, and a release area for releasing a locking abutment between the locking edges. The sidewall of the container having the locking edge associated therewith is defined by a panel having a first transverse cutline defining a top flap between the cutline and the open end of the container, with the top flap being connected to a first facing panel of the container along a foldline. An inner surface of the top flap 16 is adhered to an exterior surface of a first glue flap 10, the first glue flap being connected to an opposite facing panel of the container along a foldline. The first glue flap provides the locking edge of the container.
