In the embodiments shown in the drawings is the design of folding boxes for cigarettes. This type of packaging consists of thin cardboard. A lower box part 10 and a hinged lid 11 are closed connected to one unit. The box part 10 is made from box front wall 12, box rear wall 13, Box side walls 14, 15 and from a bottom wall 16. Analog for this purpose the cover 11 consists of the cover front wall 17, Lid rear wall 18, lid side walls 19, 20 and an upper End wall 21. Box part 10 and lid 11 are in the area along the box rear wall 13 and the lid rear wall 18 a transverse line joint 22 connected to each other.

A special feature of the present exemplary embodiments the hinged box with its upright packing edges 23, 24, 25, 26 formed as round edges, that is to say with a cross section in the form of a quarter circle with adaptation to the dimensions a cigarette. Bottom wall 16 and end wall 21 are in the area of corners rounded in an adapted manner. The Pack edges 23..26 arise when folding the blanks for the hinged box (Fig. 7, Fig. 10). For this purpose provide the blanks with edge strips 27, namely with knockouts, which here as in the longitudinal direction of the blank or the packing edges 23..26 running, narrow, parallel grooves consist.

The box side walls 14, 15 are just like the lid side walls 19, 20 double-layer or double-walled. Two each overlapping each other in at least one partial area Box side strips 28, 29 or corresponding lid side strips 30, 31 form said side walls 19, 20 and are for this purpose together by gluing or the like connected. The inside box side strips 28 connect laterally to the box rear wall 13, while the outer box side strips 29 with the box front wall are connected. The lid is designed accordingly.

With the inside lid side strips 31 are lid corner flaps 32 connected in the finished packaging on the Bearing inside the end wall 21 and glued to it are. Correspondingly, bottom corner flaps 33 with the bottom wall 16 connected.

A lid inner tab 34 closes the lid front wall 17 to the inside of the finished hinged box the lid front wall 17 is folded and connected to it.

A collar 35 also belongs to a folding box here consists of a separate blank (Fig. 3). The collar 35 consists of a collar front wall 36 and collar side walls 37, 38. The collar 35 thus formed is in the box part 10 positioned such that a lower part of the collar front wall 36 bears against the inside of the box front wall 12. The collar side walls 37, 38 lie on the inside of the box side walls 14, 15. The collar 35 is with the box part 10 connected, for example by gluing.

The relative position of the collar 35 to the box part 10 is so chosen that an upper part, namely a collar upper part 39th protrudes from the box part 10. The collar top 39 is in the closed position of the hinged box within the lid 11 positioned, namely in the area of the lid front wall 17 and Lid side walls 19, 20. The collar side walls 37, 38 lie thereby on the associated cover side walls 19, 20.

The present folding boxes come with a closing aid provided, that is, with organs that the in Fig. 1, Fig. 2 and in 9 stabilize the closed position of the hinged box shown, however, do not hinder the opening and closing process.

The locking aids in the present case consist of deformed and / or stamped sections from due to the construction a folding box existing walls of the same. In the present Trap becomes an additional closing force through interaction between the lid side walls 19, 20 on the one hand and the collar side walls 37, 38 on the other hand.

An embodiment of the locking aid results from FIG. 1 and FIGS. 3 to 5 and FIGS. 7 and 8 facing each other Walls in the area of the cover 11, namely collar side walls 37, 38 on the one hand and the inside lid side strips 31 on the other hand are provided with projections with the hinged box closed (Fig. 1, Fig. 5) with each other are positively engaged. For this purpose are in the area the collar side walls 37, 38 in the upper area, that is, inside the collar upper part 39, to the lid side walls 19, 20 directed projections 40 arranged. These are through embossing of the material of the collar side walls 37, 38 is formed. The cross section the protrusions 40 result from Fig. 4. After that given an angular cross section with a lower one inclined support surface 41. The adjoining above Wall 42 of the projection 40 is curved here. Overall the projection 40 has an arcuate contour with a transverse direction Conclusion as a support surface 41. The projection 40 is expedient in the manufacture of the blank for the collar 35 molded by embossing.

On the opposite side, i.e. on the inner cover side strips 31, a counter projection 43 is formed. This has the same geometric shape in the present case as the projection 40 with the support surface 41 directed upwards is. The relative position of projection 40 and counter-projection 43 is selected so that in the closed position of the hinged box (Fig. 1, Fig. 5) the projections 40, 43 with each other in a form-fitting manner Stand by. This means that the support surfaces 41 of the the two projections lie against each other (Fig. 5). This gives an effect of snapping into place when the hinged box is closed or snapping. When opening the lid 11 is a slight resistance to overcome.

A modified version of the locking aid results from Fig. 6 and from Fig. 9 to Fig. 11. In this embodiment only on one side, namely on the collar side walls 37, 38, a projection 44 is formed. This is the same here Designed like the projection 40 of the described exemplary embodiments, thus with support surface 41 and wall 42.

The projection 44 works with the inner lid side strip 31 together. When opening and closing the lid, it slides Projection 44 with an outward rubbing edge 45 along the inside of the lid side strip 31. Thereby there is an increased closing force in the closed position.

This effect is reinforced in the present case by the fact that the projection 44 in the closed position in a recess of the Lid 11 snaps into place, namely in a hole 46, which in Lid side strip 31 is formed. The hole 46 (Fig. 10, Fig. 11) is positioned so that exactly in the closed position of the cover 11, the snap effect occurs. The geometrical The shape of the hole 46 corresponds to that of the projection 44, so that this in the closed position of the hinged box, form-fitting takes place in the hole 46 (Fig. 9). The snap-in process when closing and opening the lid 11 is facilitated.

The locking aids can be modified in various ways be. This is especially true for those made from the material of the collar 35 or the cover 11 formed by embossing and / or stamping Ledges. In the simplest version, each can a protrusion only on the inside of the lid side strips 31 or the collar side walls 37, 38 may be arranged. At this simple version, the locking aid is exclusively caused by friction. A better effect is when added a positive engagement with other projections or with depressions or holes.
