concerning:
"Wrapping of a cuboid container"

The invention relates to a casing of a cuboid container with a long edge "a", a middle one Edge "b" and a short edge "c", consisting of a rectangular blank, the longer side (a + 2b) of which is long and the short side of which is at least (2b + 2c) long, and after it has been wrapped around the longer container surface is - is attached at the end faces folded in and laid flat. This is the most common type of such Wrap the container. There is a strong accumulation of material on the front surfaces of the container, because four Tip twice or even four times the thickness of the wrapping material be placed on top of each other. The packaging process is therefore unfavorable at this point. The "thickening" is unsightly, tends to open up, and also makes sticky labels look ugly because they are warping and wrinkling. This phenomenon is all the more disturbing, the more unfavorable the relationship between the dimensions "b" and "c" is.

Of course, nan could form the corners in a cut Cut out corners. On the one hand, that leads to one additional operation and, on the other hand, has the consequence aass one in itself arv / desired. later ialü ^ lappung car Ur.ihüllungsbahn, What comes out from the corners of the container and forms a certain protection against the ingress of moisture, etc., is not applicable. This is especially important when packing cigarettes in so-called "cartons".

The object of the present invention is to provide the casing of the type mentioned in such a way that with consistently good protection of the coated container sicn on the The front side only results in a relatively flat, well-distributed thickening of the material, so that the pack has a pleasing appearance and the labels stuck to the face remain smooth.

This object is achieved according to the invention in that the blank has two starting from its shorter edges, incisions parallel to the longer edge in the area at least an iCante "b" of each face that extends up to the bisector of the angle from the nearest gap extend, and that after folding in the outside of the incisions lying blank flaps the lying inside the incision unfolded on the aforementioned and doert is attached.

Uie still to be explained in detail, results from this design despite only very little effort for the The incision operation results in a much more favorable distribution of the "tips" on the face. It is advantageous if the incisions the section of the cut edge in the area

the container edge "b" into two outer sections equally Broad and a middle lobe with doubledF.r ^ reite like divide a section.

One can, of course, use the center in the depicted Apply "b" to both edges, but you can - which is preferred - proceed in such a way that the incisions only one edge "b" of each end face is assigned sina, while at the opposite edge incisions for training a tab with dimensions equal to the outer face are. This allows namely, the frontal large Cloth as a label at least as a closed adhesive surface for a solcnes to use.

The invention is described below with reference to attached drawings, which represent a preferred embodiment semi-schematically. the Fig. 1-6 show the individual steps involved in wrapping a container comprising eight individual packs.

Fig. 1 shows the container 10, consisting of the eight packs "P". The container has a longest edge "a", an edge "b" of medium length and a shortest edge "c". A blank 12 is provided for wrapping, the longer side 14 has a length of (a + 2c), while the shorter side 16 (2b + 2c) must be at least long; in general choose a length of (2b + 3c), as shown.

From both shorter sides 16 of the blank, incisions extend inwards parallel to the longer side 14. A first set comprises the two cuts IS of the same length; their location and depth will be discussed later. A second set comprises the two incisions 20, which are also one below the other have the same length.

In Fig. 1 it is indicated by dash-dotted lines where the blank 12 is folded around the container 10; accordingly, it can be seen that the surface parts 22, 23, 24 and 25 on the surfaces 42, 44 of the container and their respective on opposite surfaces. The protruding at the ends of the resulting rectangular tube Blank ends comprise (on the left in FIG. 1) the tabs 32, 33, 34, 35 and 36 and (on the right in FIG. 1) corresponding ones Rag that are not numbered.

During the wrapping process, starting from the surface part 22, the blank as indicated in Fig. 2 is placed around the container. The tab 34 is already at right angles inward folded over, the section between the dash-dotted line 27 and the incision 18 between lobes 34 and 35 placed on the tab 35; it creates a fold line 28 (Fig. 2), which bisects the angle below 45 ° away from the corner of the container. The incisions 18 have a depth that bisects this angle enough; their distance from the fold lines 27 and 29 (FIG. 1) is preferably about a quarter of the length of the edge "b".

During the further wrapping process, the surface part is placed on that designated by 22 and, if necessary, there attached, for example by gluing.

Thereafter, the flap 36 is folded in the same way as previously the flap 33, with the flap lying below 36 32 is turned off with (Fig, 3, 4). Only tabs 35 and 33 are now free. The tab 35 is only about half that wide like "b"; it is folded up and glued if necessary. (Fig. 5).

A09834 / 0174

The incisions 20 have been made along the dash-dotted fold lines 30, 31 and extend up to to the fold line 41. Accordingly, the tab 33 has the dimensions bxc and thus corresponds to the end face 43 of the container. Since the tab 35 lies smoothly under the tab 33, there is a fairly "thin" accumulation of material on the end face 43, so that you can easily apply a label if you do not even design the tab 33 itself as a label.

It goes without saying that in the case of the flap 33, instead of the incisions 20, such as the incisions can provide for the flap 35; however, it is not expedient, instead of the incisions 18, also along the folding lines 27, 29 cut, v / eil then the container would only be inadequately protected against moisture, etc.
