FIG. 3 shows a detailed view of the transport unit 40a. The transport unit 40a preferentially comprises at least one holding element 92a, by means of which the primary packaging 10a can be held for a transport into the secondary packaging 42a. The holding element 92a may, for example, be realized as a negative-pressure holding element, like for example as a suction cup (the holding element realized as a suction cup is depicted in FIG. 3 by a dashed line and has no reference numeral).

    [0049] In at least one method step 50a the primary packaging 10a is supported during a transport, in particular a transport into a secondary packaging 42a, at least in the region of the fold triangle 26a, 28a of the enveloping unit 14a, and/or the fin 22a, 24a of the enveloping unit 14a is bent, arched and/or folded around at least the axis 44a, 46a. In at least one, in particular alternative or further, method step 52a the fin 22a of the enveloping unit 14a of the primary packaging 10a is bent, arched and/or folded around the axis 44a as a result from a contact with an inner wall 54a (see FIGS. 5 and 6) of the secondary packaging 42a and, in particular directly after this, a pivoting movement of the primary packaging 10a is effected, in particular by means of the transport unit 40a, in which the further fin 24a of the enveloping unit 14a of the primary packaging 10a is bent, arched and/or folded around the further axis 46a. The pivoting movement of the primary packaging 10a is effected preferably around a pivot axis of the transport unit 40a that extends at least substantially parallel to a main support surface 106a of the support unit 104a, in particular toward the support unit 104a.

    [0050] In at least one, in particular alternative or further, method step 56a, during a laying-in into the secondary packaging 42a, the fin 22a of the enveloping unit 14a of the primary packaging 10a is bent, arched and/or folded around the axis 44a as a result from a contact with the inner wall 54a of the secondary packaging 42a and, in particular directly after this, a folding of an outer wall 58a (see FIGS. 5 and 6) of the secondary packaging 42a is effected, in which the further fin 24a of the enveloping unit 14a of the primary packaging 10a is bent, arched and/or folded around the further axis 46a.

    [0051] When a plurality of primary packagings 10a have been arranged in the secondary packaging 42a according to at least one of the method steps described above, in the arrangements illustrated by way of example in FIGS. 5 and 6, a protective sleeve (not shown in detail) of the secondary packaging 42a is arranged around the support unit 104a and the primary packagings 10a which are arranged thereon by the packaging machine 38a.

    [0052] Alternatively to a row-wise arrangement of the primary packagings 10a in the secondary packaging 42a, as shown in FIGS. 5 and 6, it is also conceivable that in at least one method step 60a the primary packaging 10a and at least one further primary packaging (not shown here in detail) are arranged in the secondary packaging 42a in a shingled or cross-wise manner in such a way that fins 22a, 24a of the primary packaging 10a and the further primary packaging are arranged essentially overlap-free or contact-free. Further implementations deemed expedient by someone skilled in the art are also conceivable.

    [0053] In FIG. 7 a further exemplary embodiment of the invention is shown.
