The locking tongue 59 is already bent at an angle which is more than 90 °, as shown in FIG. 7 can be seen 1st. At the same time, the holding tongue 63 is already bent out of the plane of the overlapping surface 48 at an angle which is substantially less than 90 °. Is the radial tongues greifeleaent 98 from its in Pig. 7 is pulled into its initial position, the locking tongue 59 is arranged essentially vertically due to its natural elasticity and the free end of the retaining tongue 63 abuts against the locking tongue 59. In other words, according to the present invention, the radial tongue element 98 is activated by means of the tilting shaft 94 la angle sa dan planes of the overlapping surfaces 48 and 5o, as clearly shown in FIG. 5 _f 6, '7 and θ is Taranaohanlicht. Therefore, according to the present invention, it is impossible for the retaining tongue, such as, for example, 63t «nt *! · Wsrriegelungszunge, such as 59, to lie flat against one another against the wall surfaces 48 and So, so that the security of the locking arrangement is greatly improved.

It goes without saying that the circumferential locking element, designated as “all-fine old 89”, is eynohrom for the handling of the cardboard boxes and the primary packaging assigned to them. As shown schematically in flg. 9, the tongue gripping element, such as 98, is rotated clockwise ms the axis of the shaft 94 and is preferably moved from left to right at the speed assigned to the cardoaa as soon as the locking element 98 In vertical, old X basal hard position.
