Definitions

• the invention relates to a pack for tobacco products, in particular cigarettes, made of at least one blank of foldable packaging material, such as paper, cardboard or the like, surrounding the pack contents, folding flaps of the blank, in particular bottom-folding flaps, covering one another (in part) and being connected to one another by glue and a Z-fold of the blank is also formed adjacent to an (upper) end wall and / or adjacent to a (lower) bottom wall.
• foldable packaging material such as paper, cardboard or the like
• cigarette packs of the soft cup type in a modified version, namely preferably from a single blank of paper or comparable packaging material.
• a pack of this type it is provided at least in a region adjacent to an end wall with a multiple fold running all around, namely in particular a Z fold (US Pat. No. 4,508,218).
• a cigarette pack in the area of a bottom wall can be provided with material reinforcements, namely a double-layer material, from which correspondingly double-layer bottom folding flaps of the bottom wall are formed (US Pat. No. 5,762,186).
• the invention is concerned with improvements in particular to cigarette packs of the aforementioned designs.
• the invention has for its object to design packs of the aforementioned and similar design so that an improvement in the external appearance and an improved quality assurance for the pack contents are guaranteed.
• the pack according to the invention is characterized in that, on the one hand, between the folding tabs connected by glue and the pack content, on the other hand, a cover flap is arranged against the transfer of glue to the package contents.
• the invention is based on the knowledge that the gluing of folding tabs of the pack, in particular the gluing of bottom-folding tabs of a bottom wall, entails the risk that glue particles are transferred to the contents of the pack, in particular to end regions of the bottom wall of the pack neighboring cigarettes.
• the cover flap according to the invention protects the end faces of the cigarettes against glue transfer.
• the cover flap is expediently part of the cut in the region of the base wall, that is to say connected to it, preferably as an extension or addition or extension of a base corner flap which is usually positioned on the inside. This is a continuation of one of the narrow, upright side walls of the pack.
• the procedure according to the invention is such that the cover flap is part of the double-layered material strip in the region of the bottom wall, but does not participate in the reinforcement of the package in this region. Rather, a floor corner flap is created by means of corresponding die cuts, the length of which corresponds to the width of the double-layer material strip. In the finished pack, this extended floor corner flap lies against the inside of the floor wall and forms the cover flap.
• a plurality of layers can arise in the region of an overlap of side tabs to form a side wall due to overlap.
• a recess is provided in the area of the Z-fold or the overlap thereof, at least in the area of one of the layers, which creates a local, edge-side layer reduction.
• a connection of the layers by means of glue is expediently provided in this area, so that a correct formation of the pack is ensured.
• FIG. 1 shows a modified cigarette pack of the soft cup type in a perspective view
• FIG. 1 shows a greatly enlarged detail as a detailed illustration of FIG. 5,
• FIGS. 1 to 6 shows a blank for a pack according to FIGS. 1 to 6 in the expanded state
• FIG. 8 shows the blank according to FIG. 7 in an intermediate position 1.
• the (cigarette) pack of the type soft cup in a modified design shown in perspective in FIG. 1 consists of a single, one-piece blank (FIG. 7, FIG. 8).
• the rectangular blank surrounds the pack contents (a group of cigarettes) in such a way that front wall 10, rear wall 11 and side walls 12, 13 are formed.
• the side wall 13 is formed from two side flaps 14, 15 on the edge, which partially overlap one another, the wider side flap lying on the outside and covering almost the width of the side wall 13.
• the side tabs 14, 15 are connected to one another by adhesive bonding, in the present example by a plurality of glue dots 16.
• the blank forms an end wall 17. Opposite is a bottom wall 18. End wall 17 and bottom wall 18 are formed by a plurality of folding tabs which partially overlap one another.
• the bottom wall 18 consists of bottom folding tabs, namely bottom longitudinal tabs 19 and 20 and bottom corner tabs 21, 22 on the other hand.
• the respective trapezoidal floor longitudinal tabs 19, 20 are connected to the front wall 10 on the one hand and the rear wall 11 on the other hand.
• the narrower floor corner flaps 21, 22 are connected to the side wall 12 on the one hand and the side wall 13 on the other hand or are extensions of the same.
• the bottom corner flaps 21, 22 form the inside of the bottom wall 18, while the bottom longitudinal tabs 19, 20 are on the outside.
• the bottom longitudinal tabs 19, 20 are connected to one another by gluing, for example by glue points or the like.
• a bottom-side region of the blank or of the pack, namely a folding strip 24, is double-agile.
• the folding strip 24 consists of two partial strips 25, 26.
• the outer partial strip 26 formed at the free edge is folded over along a folding line 27 to form the double-layer folding strip 24.
• the floor tabs described are formed from the double 1-fold folding strip 24.
• a cover flap is formed on the inside of the bottom wall 18, specifically between the bottom wall 18 and the contents of the pack.
• the cover flap protects the contents of the package against the transfer of glue particles when gluing floor folding flaps.
• the cover flap is formed by a bottom flap, specifically by the bottom corner flap 21 connected to the side wall 12.
• the bottom corner flap 21 is not double-layered for this purpose. Rather - the bottom corner flap 21 remains in the length predetermined by the width of the folding strip 24, that is to say essentially twice as long as the bottom corner flap 22.
• the blank is prepared for this by punching lines 28, 29. These extend at the lateral boundaries of the bottom corner flap 21, specifically in the area of the folding strip 24, that is to the fold line 27.
• an additional length results from an edge strip 30 attached to the free side of the folding strip 24. In the finished pack, this extends as an inside reinforcement in the region of the front wall 10, rear wall 11 and side walls 12, 13 (FIG. 2. ).
• the bottom corner flap 21, which is dimensioned accordingly in the longitudinal direction of the side wall 12, extends along the inside of the bottom wall 18 to the opposite bottom corner tab 22 or beyond it (FIG. 2, FIG. 3).
• the contents of the pack are accordingly covered over the entire area by the bottom corner flaps 21, 22 compared to the longitudinal bottom tabs 19, 20 lying on the outside. These are folded in a manner analogous to the end wall 17 and connected to one another.
• the gluing of the bottom folding tabs, namely the bottom longitudinal tabs 19, 20, is expediently carried out in a position corresponding to FIGS. 2 and 3.
• the contents of the pack namely the facing ends of the cigarettes, are covered throughout, namely by the single-layer floor corner flaps 21 on the one hand and through the adjoining floor corner flaps 22 on the other hand.
• Another special feature of the invention also relates to the design of the pack in the area of the multilayered design of the blank.
• the present exemplary embodiment is concerned with a multilayer material strip 31 running around the end wall 17 or immediately below it, which is designed as a Z-fold.
• the blank (FIG. 7) is provided in a front area with a folding strip 32, which is used to form front end flaps, analogous to the design of the bottom wall 18. Accordingly, the front end flaps 33 are formed, 34 and the narrower front corner flaps 35 and 36.
• the front corner flap 36 is partially double-layered, namely analogous to the side wall 13.
• an additional material strip is formed, namely a Z-folding strip 37.
• This consists of two partial strips, namely for legs 38, 39 of the Z strip. Folding.
• the strip-shaped legs 38, 39 are delimited from one another by a Z-fold edge 40 and from the fold strip 32 by a fold edge 41 and from the front wall 10, rear wall 11 etc. by a further fold edge 42. These each form deflection edges of the material in the finished Z-fold (FIG. 5).
• the design of the material strip 31 results in an accumulation of material 1 agen (Fig. 6). This can lead to an undesired opening of the fold in this area.
• material layers are eliminated in the overlap area, so that the total number of layers overlapping one another is locally reduced.
• layers lying on the inside, that is to say covered on the outside are preferably provided with recesses, holes, cutouts or the like.
• an edge that is open toward the free edge is on the edge Recess 43 arranged.
• This is V-shaped and extends approximately centrally in the area of the Z-fold tstrei fens 37, that is, on both sides of the Z-fold edge 40th
• the Z-fold is first formed in the area of the otherwise flat blank (FIG. 8).
• the package contents are then encased by the blank prepared so far, the material covering being created in the region of the side wall 13.
• the recess 43 is arranged in the region of the Z-fold strip 37 facing the (outer) side tab 15. Due to the internal Z-fold (FIG. 6), the recess 43 in the finished pack is covered on the outside by an upper region of the side tab 15. Below the side tab 14, the shape and arrangement of the recess 43 result in a local material or layer reduction , namely in the area of the legs 38 and 39.
• a particularly correct and durable connection in the region of the overlap of the ends of the multi-layer material strip 31 is given if 43 material 1 agen are connected to one another by gluing in the region of the created recess.
• a glue point 44 is positioned in the region of the recess 43.
• the (outer) side tab 15 is connected directly to the inner side tab 14, through the recess 43.
• the arrangement of the glue point 44 is selected such that it is positioned centrally to a (double) edge 45 delimiting the recess 43. Due to the glue point 44, the outer side tab 15 is also connected to the facing leg 39 of the Z-folding tstrei fens 37.
• the blanks described are expediently separated from a continuous web of material by transverse separating cuts, the Z-folding strip 37 expediently extending in the longitudinal direction of the web.
• the recess 43 is through or with a transverse cut for the Blanks attached by appropriate design of a cutting knife. In the subsequent cut, this results in a projection or a tongue 46 in the form of the recess 43 and in continuation of the Z-folding tstrei fens 37. This tongue 46 disappears on the inside in the finished pack.
