A packet for smoking articles includes: a group of smoking articles; a container having a containing portion for receiving the smoking articles, wherein an empty space, devoid of smoking articles, is defined in the containing portion; a covering body of said container having a tubular wall extending along a reference axis, within which the container is inserted and configured for moving along the reference axis, between a safety position wherein the container is in a retracted condition within the covering body and access to the group of smoking articles is impeded, and a use position wherein the container is in an extracted condition with respect to the covering body for providing access to the group of smoking articles. The packet may include a blocking system arranged to prevent movement of the container from the safety position to the use position and to enable this movement via an unlocking element.
