Abstract

To prevent the transfer of glue onto the contents of the packet a cover tab is located between the glued-together folding flaps on one side and the contents of the packet on the other side. The cover tab is located in the region of the bottom side(18) of the packet on its inner side. The cover tab is part of the blank, especially an enlarged bottom corner tab(21), which forms the tab on the bottom inner side and is preferably complementary to an opposite lying corner tab(22).

Description

The invention relates to a pack for tobacco products, in particular cigarettes, from a single blank of foldable material surrounding the contents of the package Packaging material, such as paper, cardboard or the like, with folding flaps the blank, namely bottom folding tabs to form a bottom wall, each other partially covered and connected by glue.

Cigarette packs of the type soft pack are so far predominantly as Soft container pack running, so with a separate inner blank Paper or tinfoil and an outer cup open at the top. The cigarettes are completely surrounded by the Innenumhüllung. Their folding flaps in the The area of the front wall and the bottom wall are without glue at the ends of cigarettes (US 5,762,186).

But also a soft pack for cigarettes, which consists of a single, US 4 508 218) is applied directly to the cigarette fitting blank. at This blank bottom flaps are connected by glue together. As a result, there is a risk that glue from the area of these floor flaps reaches the free ends of the cigarettes.

The invention is based on the object packages of the initially described Art to further develop that the package content, in particular the cigarettes are protected against transmission of glue.

a) zwischen den durch Leim miteinander verbundenen Faltlappen der Bodenwand einerseits und dem Packungsinhalt andererseits ist ein Abdecklappen angeordnet zum Schutz gegen Übertragung von Leim auf den Packungsinhalt,

b) ein vergrößerter Boden-Ecklappen des Zuschnitts bildet als innenseitiger Teil der Bodenwand den Abdecklappen, vorzugsweise in Ergänzung zu dem gegenüberliegenden Boden-Ecklappen.

To solve this problem, the package according to the invention is characterized by the following features:

a) between the glue-connected folding flaps of the bottom wall on the one hand and the package contents on the other hand, a cover flap is arranged to protect against transmission of glue to the package contents,

b) an enlarged bottom corner tabs of the blank forms the inner side part of the bottom wall of the cover tabs, preferably in addition to the opposite bottom corner tabs.

The invention is based on the finding that the gluing of folding flaps the packing, in particular the gluing of bottom folding flaps of a bottom wall, there is a risk that glue particles are transferred to the contents of the package be, in particular to end portions of the adjacent to the bottom wall of the pack Cigarettes against glue transfer.

The cover flap in the region of the bottom wall is expediently part of the blank, So connected with this, as an extension or supplement a usually inside positioned floor corner flap. This one is one Continuation of one of the narrow, upright sidewalls of the pack.

The details shown in the drawings relate to further developments and Improvements to (cigarette) packages, in particular in the execution according to US 4,508,218 and US 5,762,186.

The in Fig. 1 perspective shown (cigarette) pack of the type soft cup in modified version consists of a single, one-piece blank (Fig. 7, Fig. 8th). The rectangular blank surrounds the package contents (a group of cigarettes) such that front wall 10, rear wall 11 and side walls 12, 13 arise. The side wall 13 is formed of two marginal side flaps 14, 15, the other partially cover, with the wider side lobe outside and almost the width the side wall 13 is covered. The side flaps 14, 15 are by gluing together connected by a plurality of glue dots 16 in the present example.

At the top, the blank forms an end wall 17. Opposite is a bottom wall 18th end wall 17 and bottom wall 18 are partially separated by several Covering folding flaps formed. The bottom wall 18 consists of bottom folding flaps, namely bottom longitudinal tabs 19 and 20 and bottom corner tabs 21, 22 on the other. The each peg-shaped bottom longitudinal flaps 19, 20 are connected to the front wall 10 on the one hand and the rear wall 11, on the other hand. The narrower bottom corner tabs 21, 22 are connected to the side wall 13 on the other hand, or continuations thereof. The Bottom corner tabs 21, 22 form the inside of the bottom wall 18, while the bottom longitudinal tabs 19, 20 are outside. The bottom-long flaps 19, 20 are by gluing interconnected, for example, by glue spots or the like.

A bottom area of the blank or package, namely a folding strip 24, is double-layered. The folding strip 24 consists of two partial strips 25, 26. The outer, formed at the free edge strip portion 26 is along a fold line 27 for forming of the two-ply folding strip 24 folded over. From the double-layered folding strip 24 The described floor tabs are formed.

On the inside of the bottom wall 18, a cover flap is formed, between the bottom wall 18 and the contents of the package. The cover protects the contents of the package before the transfer of glue particles during the bonding of floor flaps.

The cover flap is in the embodiment shown by a bottom flap formed, through the connected to the side wall 12 bottom corner tabs 21. The bottom corner tab 21 is not formed double-layered for this purpose. Much more the bottom corner tab 21 remains in the predetermined by the width of the folding strip 24 Length, that is substantially twice as long as the bottom corner tabs 22. The blank is prepared for this purpose by punching lines 28, 29. These extend the lateral boundaries of the bottom corner tab 21, in the Berich the folding strip 24 so to the folding line 27. This allows the areas of the partial strip 26th folded over to form the bottom longitudinal tabs 19, 20 and the bottom corner tabs 22 while the bottom gussets 21 remain unfolded and thereby correspondingly has greater length. In the present embodiment results an additional length by enen attached to the free side of the folding strip 24 Edge strip 30. This extends in the finished pack as inside reinforcement in the area of front wall 10, rear wall 11 and side walls 12.13 (FIG. 2).

The corresponding in the longitudinal direction of the side wall 12 sized bottom corner tabs 21st extends along the bottom wall 18 on the inside to the opposite floor corner tabs 22 or over this time (Fig. 2, Fig. 3). The contents of the pack are accordingly over the entire surface covered by the bottom corner tabs 21, 22 opposite the outside adjacent bottom longitudinal tabs 19, 20. These are anlalogen in a to the end wall 17 Way folded and connected. The gluing of the ground folding folders, namely, the bottom longitudinal tabs 19, 20 is advantageously carried out in one position according to Fig. 2 and Fig. 3. The contents of the package, namely the facing ends The cigarettes are covered throughout, namely by the single-layered Floor corner tabs 21 on the one hand and by the subsequent bottom corner tabs 22nd on the other hand.

Another feature of the invention also relates to the design of the Packing in the area of multilayer training of the blank. In the present Embodiment is about an adjacent to the end wall 17 or directly below the same surrounding multi-layered material strip 31. This is as Z-fold formed.

The blank (Figure 7) is for this purpose in an end-face area with a fold strip 32 provided, which serves to form Stim folding flaps, analogous to the embodiment the bottom wall 18. It is therefore the formation of Stimlängslappen 33, 34 as well as the narrower Stin gussets 35 and 36. The Stim gusset 36 is partial formed double-layered, namely analogous to the side wall 13th

Between the folding strip 32 and the area with front wall 10, rear wall 11, etc. is formed an additional strip of material, namely a Z-fold strip 37th This consists from two partial strips, namely for legs 38, 39 of the Z-fold. The strip-shaped Legs 38, 39 are separated from each other by a Z-folding edge 40 and by the folding strip 32 by a folding edge 41 and front wall 10, rear wall 11, etc. by another Folded edge 42 delimited. These form each deflection edges of the material in the finished Z-fold (Fig. 5).

In the area of the side wall 13 results from the design of the material strip 31st an accumulation of material layers (Fig. 6). This can lead to an unwanted opening folding in this area. To counter this phenomenon, are in the overlapping area material layers so that the total number of each other overlapping layers is locally reduced. For this purpose are preferably inside lying, so outwardly covered layers, with recesses, extinguishing, punching or the like provided.

In the present embodiment is in the region of the Z-fold strip 37 edge a recess 43 open towards the free edge is arranged. This is V-shaped and extends approximately in the center of the Z-fold strip 37, ie to both Sides of the Z-fold edge 40.

In the manufacture of the package, the Z-fold is first in the area of the remainder flat blank formed (Fig. 8). Thereafter, the contents of the package will be so far vorübereiteten blank wrapped, with the Materalüberdeckung in the side wall 13 arises. The recess 43 is in the (outer) side lobe 15 facing Area of the Z-fold strip 37 is arranged. Through the inside Z-fold (FIG. 6), the recess 43 in the finished package is covered on the outside by an upper portion of the Steitenlappens 15. Below the side flap 14 results by the shape and arrangement of the recess 43, a local material or layer reduction, namely in the region of the legs 38 and 39.

A particularly correct and durable binding in the area of the overlapping of the ends of the multilayer material strip 31 is given when in the area created Recess 43 material layers are bonded together by gluing. In which In this example, a glue point 44 is positioned in the region of the recess 43. As a result, the (outer) side tabs 15 directly with the inside Side tabs 14 connected through the recess 43 therethrough. In the shown Embodiment (Fig. 8), the arrangement of the glue point 44 is selected so that this centered to a recess 43 limiting the (double) edge 45 positioned is. By the glue point 44 thereby at the same time also the outer side flap 15 with the facing leg 39 of the Z-fold strip 37 is connected.

The blanks described are expediently of a continuous material web divided by Quergenchtete separating cuts, with the Z-fold strip 37th expediently extends in the longitudinal direction of the web. The recess 43 is thereby attached by or with a transverse separating cut for the blanks by appropriate design of a separating knife. In each case following Blank is created by a projection or a tongue 46 in the form of the recess 43 and in continuation of the Z-folding strip 37. This tongue 46 disappears inside of the finished package.
