19 by the incision 23 is formed into an extension 24 which runs in the same plane as the cover 15 the extension 24 thus projects beyond the free periphery 17 of the cover 15 and makes it easier for the cover to be manipulated for example for opening purposes the latching opening 22 and a latching protrusion 25 together form latching means 26 the latching protrusion 25 is provided symmetrically to the center of an insertion opening 27 the latter extends within the upper wall 8 parallel to the front upper edge 28 of the container this upper edge being formed by a second folding line 29 the edge 28 and thus the second folding line 29 in the closed state of the cover are closely adjacent to the free periphery 17 and to the connecting edge 21 which is formed by a first folding line the insertion opening 27 is dimensioned so as to allow the insertion tab 19 to be inserted while the latching protrusion 25 is bent away elastically in the process this latching protrusion latches into the latching opening 22 as soon as the cover 15 is fully closed i e the underside thereof butts at least more or less against the upper side of the wall 8 the cover can then only be opened with the latching protrusion 15 being bent away elastically until it releases the latching opening 22 as can be seen in particular in fig2 which shows a first exemplary embodiment of a blank of thin cardboard prior to being folded into the pack according to the present invention it is possible for.
