Abstract
The packaging sleeve has at a first end (4) thereof an extended (11) back wall (1) and extended (31) side walls (3) connected thereto. The sleeve is closed at the first end (4) by a lid (21) connected to the front wall (2) and provided with a closing flap (23) which extends into the sleeve and is kept enclosed by side flaps (33), which extend from the side walls (3) and which are overlapped by the closing flap (23).
