Description

[0001] Packaging for a product, especially a food product

[0002] The invention relates to a packaging for a product, wherein the packaging is particularly suitable for packaging free-flowing food products.

[0003] Free-flowing products, in particular, are often packaged in bags. These come in a variety of shapes and sizes. The most important examples are pillow bags, gusetted bags, block-bottom bags, 4-corner seal bags, doy bags, etc. The products / bags are presented either upright or horizontally in the sales area. However, from a retailer's perspective, the upright presentation is often more attractive and preferred, as product information and marketing can be arranged directly in the consumer's field of vision on one surface of the bag. Furthermore, upright bags can often be arranged more neatly in the outer or transport packaging.

[0004] To enable a bag to be presented upright, it must be stable enough to prevent it from tipping over. However, the production of such stable bags is typically somewhat more complex because special mold designs are required to create a base and, in some cases, stronger (and more expensive) materials must be used. This is also reflected in slower cycle times on a packaging machine.

[0005] Another common form of packaging that has these disadvantages and advantages is bag-in-box packaging. For example, cereals are often offered to consumers in a bag and folding box. This naturally results in higher material usage. The additional outer carton may allow for the use of thinner film materials. However, the total material usage (bag + outer carton) is usually higher.

[0006] The object of the present invention is to at least partially solve the problems described with reference to the prior art. This object is achieved by the invention according to the features of the independent patent claims. Further advantageous embodiments are specified in the dependent claims as well as in the description and, in particular, in the description of the figures. It should be noted that the person skilled in the art can combine the individual features in a technologically expedient manner and thus arrive at further embodiments of the invention.

[0007] What is described here is a packaging for a product, comprising a bag for holding the product, and a cardboard sleeve arranged outside around the bag, wherein the bag has a flattened shape with two opposing flattened bag surfaces, and wherein the cardboard sleeve has a cardboard base surface which forms a standing surface of the packaging, and two cardboard surfaces which adjoin the cardboard base surface opposite one another and extend upwards from the cardboard base surface, which are connected to the cardboard base surface by first fold lines and cover the flattened bag surfaces, wherein exposed regions of the bag are arranged between the upwardly extending cardboard surfaces.

[0008] The invention allows the upright presentation of a pillow bag using a carton sleeve, which significantly reduces the material used in a bag-in-box by up to 40%. Advantages over existing solutions: Fast production speeds of pillow bags compared to the slower manufacturing speed of rigid bags, product protection through a carton sleeve with significantly lower material consumption compared to a bag-in-box. Solution: Cost reduction through higher speeds and lower material costs.

[0009] The bag is preferably made of a plastic material and is flexible. Preferably, the bag has little or no inherent mechanical stability and would not be stable. Preferably, the bag itself also has no base. Preferably, the bag is made of a tubular material, each end of which is sealed with a straight sealing seam, where the tubular material is pressed flat and welded to itself.

[0010] The term "sleeve" refers to a cardboard border that surrounds the bag and forms the described base. The sleeve ensures the bag remains aligned in an upright position on the base.

[0011] The term "cardboard" refers to a sheet material consisting essentially of fibers (particularly fibers of plant origin) and preferably formed by dewatering a fiber suspension. Compared to paper, a "cardboard" exhibits, in particular, increased mechanical strength. Preferably, the "cardboard" has a minimum weight per square meter of cardboard surface of 130 g / m². 2 [grams / square meter],

[0012] Exposed areas here refer to areas that are not covered by the cardboard sleeve when the packaging is unopened (especially in its intended state, as presented in a sales area). The bag is visible from the outside in the exposed areas. These exposed areas can also be understood as recesses in the cardboard sleeve, for example.

[0013] A crease line of the carton or carton sleeve is an area in which a surface of the carton is folded over so that two carton partial surfaces are formed which are movable relative to each other around the crease line.

[0014] The bag has a flattened shape with flattened bag surfaces. As already explained above, the bag is preferably made from a tubular starting material. This starting material is preferably slightly flattened and at the ends of the bag (where the tubular starting material is connected to itself, for example with a closure seam) is even completely flattened in order to form the flattened shape with flattened bag surfaces. The flattened bag surfaces lie opposite one another. Between the flattened bag surfaces are regions of the bag that can be referred to as narrow sides (or narrow sides). The narrow sides preferably also form the exposed regions of the bag. The flattened bag surfaces are preferably covered by the cardboard sleeve and in particular by the upwardly extending cardboard surfaces of the cardboard sleeve.

[0015] The carton base surface or the standing surface and the upward extension direction of the carton surfaces preferably refer to a geodetic orientation of the packaging in an arrangement for presentation in a sales area. When the bag is arranged as intended in a sales area, it stands on the standing surface or the carton base surface, and the carton surfaces extending from the carton base surface face upward.

[0016] From the user's perspective, the packaging comprising the cuff and the bag is preferably a part in which the cuff and the bag are firmly connected to one another. This applies in particular when the packaging is used for its intended purpose. The cuff and the bag are connected to one another during production of the packaging and are preferably not detachable from one another without damage. If necessary, however, it is possible to separate the cuff and bag for separate recycling. At least, separation and later reassembly of the cuff and bag is not intended when the packaging is used for its intended purpose. The cuff serves to permanently stabilize the bag during use. From the user's perspective, the cuff and the bag together form the packaging.

[0017] This packaging efficiently provides additional protection and stability for a product provided in a bag with the aid of a cardboard sleeve. The cardboard sleeve is formed, in particular, from a cardboard blank that essentially corresponds to the width of the bag and is folded over at two crease lines (each on the side of a section forming the cardboard base surface), thus forming cardboard surfaces that form the two side parts, which essentially correspond to the height of the bag. The depth of the cardboard base surface preferably corresponds to the depth of the bag (perpendicular to the flattened bag surfaces).

[0018] The product that can be placed in the packaging or bag is, in particular, a product that lacks permanent mechanical stability on its own. To present such products in a standing package, it is necessary to ensure sufficient stability and uprightness within the packaging.

[0019] The product is, in particular, a free-flowing product. The product can also be fully or partially viscous. The product is, for example, a liquid or a paste. Another type of product that can be incorporated into the packaging or bag are products that exhibit temporary but not permanent mechanical stability, for example, compactable powdered products whose powder particles temporarily adhere to one another (particularly after compaction). Such products may not be free-flowing. The product can be, for example, one of the following products: flour, coffee, tea, sugar, salt, cereals, muesli. This list is not exhaustive.

[0020] If necessary, even a product which in principle does not require packaging with mechanical stability can be packaged in the packaging described here. This can happen, for example, because the packaging described here is advantageous for the respective product for other reasons, such as for marketing reasons or because the packaging was chosen to enable a user to handle the product particularly conveniently. In design variants, the fill quantity of the product in the packaging may be set in such a way that the product cannot develop its own mechanical stability in the packaging itself, but the product would be able to develop its own stability with a different fill quantity. This can apply, for example, to products such as flour.Flour can be packaged in a standard flour paper bag and can be packed so tightly within such packaging that the inherently flexible packaging, combined with the tight packaging of the product, creates a mechanical rigidity between the packaging and the product. If the flour is packaged in the packaging described here, it is advisable to fill the packaging less or not completely. This can significantly simplify handling for the user when the packaging is open, because the opened packaging may then also have sufficient stability, and removing the product from the packaging may be easier.

[0021] In addition to the advantage that the packaging described here requires relatively little cardboard and bag material overall, because the cardboard material or cardboard sleeve does not completely enclose the bag, while at the same time the bag can be made of a thin material, there are further advantages. Another advantage is that the cardboard material of the cardboard sleeve and the bag material can be easily separated mechanically. This improves the possibilities for recycling the bag material and the cardboard material separately.

[0022] Preferably, the bag consists of a flexible bag material, which preferably has at least one barrier layer.

[0023] The flexible bag material may in particular comprise / be a film material which is formed, for example, with plastic and may have been produced by extrusion blow molding or other suitable manufacturing processes.

[0024] The flexible bag material can also be flexible paper in certain versions.

[0025] The packaging described allows the bag material to be processed without any layer breaks (overlapping sections of bag material). If the bag material is provided as a tubular raw material, only two closure seams are required to close the bag once the product has been filled into the bag. This allows the use of materials for the bag that are not suitable for more complex bag shapes (which inherently guarantee stability) – for example, bags made of sustainable materials (fibrous materials, monomaterials, etc.). This also allows for a tight seal, which can effectively protect sensitive goods.

[0026] The at least one barrier layer serves, in particular, to protect the product in the packaging. The at least one barrier layer can serve to prevent certain substances from the environment from penetrating the packaging bag and damaging the product. These include, in particular, air and moisture. The at least one barrier layer can also serve to prevent product components from escaping through the packaging bag. Such product components include, for example, aromas and flavorings. Such barrier layers are very important, for example, when the product is coffee.

[0027] Depending on the type of product, suitable barrier layers may be provided. Vapor barrier layers can be used as a barrier layer and serve to protect against moisture penetration. Barrier layers can be provided to prevent the escape of aromas. Such barrier layers preferably have low permeability to molecules of any type. Barrier layers can be used to prevent the passage of oxygen.

[0028] In packaging designs for certain products and product groups, barrier layers can be omitted entirely. For example, for products such as flour or sugar, a (separate) barrier layer is usually not required; instead, paper as the bag material may be sufficient.

[0029] The barrier layer can be a stand-alone layer that is bonded to another layer (in particular a carrier layer) of the bag. The barrier layer can also be applied to a carrier layer of the bag, for example, printed, vapor-deposited, or lacquered.

[0030] It is particularly advantageous if the bag is made of a transparent material so that a product contained in the bag is visible in the exposed areas of the bag.

[0031] For promotional purposes, it is often very advantageous for product presentation in a retail space if the product itself is visible within the bag. Completely transparent packaging is often disadvantageous because explanations or advertising displays are not possible on completely transparent packaging. Viewing windows in packaging are often complex to produce because transparent materials must be combined to form viewing windows and opaque materials to provide space for advertising displays.

[0032] The packaging described above allows for transparent areas where the product inside the bag is visible. Advertising space can also be provided on the cardboard sleeve.

[0033] It is also advantageous if the bag is attached to the cardboard base surface of the cardboard sleeve.

[0034] The fastening is preferably designed in the form of a permanent connection between the bag and the cardboard sleeve, which is preferably not detachable without damaging the bag and / or the sleeve and whose dissolution during use of the packaging for its intended purpose of storing the product is also not intended.

[0035] In preferred embodiments, the bag is glued to the base surface. It is also conceivable for the bag to be attached to the base surface of the cardboard sleeve using a provided device (e.g., a tab or something similar), thus forming a plug-in connection. Welding the bag to the base surface is also possible in principle.

[0036] Particularly advantageous is a detachable attachment of the bag to the cardboard base, for example, using an adhesive that can be separated at a certain release force. This allows the cardboard sleeve and bag to be separated for recycling. Hot melt adhesives are particularly used as the adhesive material for the adhesive bonds between the bag and the cardboard surfaces of the cardboard sleeve.

[0037] It is advantageous if the upwardly extending cardboard surfaces are connected to each other on both sides by at least one cardboard connecting web at a position of the packaging spaced from the base, wherein the cardboard connecting webs are connected to one of the upwardly extending cardboard surfaces and to the other upwardly extending cardboard surface by second folding lines. The connection is implemented in particular with an adhesive connection or a plug-in connection.

[0038] Preferably, the position spaced from the base is arranged opposite the base on an upper side of the packaging. The connecting webs, together with the upper edge surfaces of the upwardly extending cardboard surfaces, preferably form a frame that surrounds an opening of the packaging when the packaging is opened.

[0039] It is also advantageous if the cardboard connecting webs are each divided into at least two cardboard web segments separated from one another by third folding lines, so that a deformation of the cardboard connecting webs at the third folding lines enables a change in the distance between the upwardly extending cardboard surfaces on an upper side of the packaging, so that an access area into the packaging can be expanded.

[0040] Before the user opens the package in the form in which it was manufactured, the connecting strips are always "folded together." In this state, the two cardboard surfaces preferably converge from the bottom surface of the carton or the base surface, and the package has a linear closure in its upper area.

[0041] When the package is opened, the cardboard connecting bars can be unfolded and the converging cardboard panels can be moved apart, creating a gap between the cardboard panels limited by the length of the cardboard connecting bars. A package opening is defined by the spacing between the cardboard panels and the width of the cardboard panels at the top of the package.

[0042] It is also advantageous if, in an access area on a top side of the packaging, the bag has an opening line at which the bag can be separated in order to open the bag.

[0043] The bag and the carton panels can preferably be severed together at the opening line. A (top) closure seam of the bag is preferably located above the opening line and can be separated from other parts of the package when the bag and the carton panels are severed at the opening line. Once the (top) closure seam is severed, the two flattened bag panels and the carton panels are no longer connected by this (top) closure seam and can be moved apart to open the bag or package.

[0044] Furthermore, it is advantageous if the flattened bag surface is connected to the upwardly extending cardboard surfaces with at least one linear connection, at least in an upper region opposite the base. The linear connection is, in particular, a linear adhesive bond. Alternatively, it can also be a weld, for example.

[0045] Preferably, at least one adhesive bond exists between each of the two flattened bag surfaces and the cardboard surfaces covering the flat bag surfaces. The two covering cardboard surfaces are thus preferably connected to the bag via the two adhesive bonds and indirectly via a bag closure seam. The two adhesive bonds and the bag closure seam together ensure that the two cardboard surfaces at the top of the package cannot be moved apart (or can only be moved apart to a small extent) when the package is closed.

[0046] Such an adhesive bond can preferably ensure that the bag is held to the cardboard surfaces and stands within the cardboard sleeve. The adhesive bond preferably fixes the bag to the cardboard surfaces of the cardboard sleeve both when the packaging is closed and when the packaging or bag is opened.

[0047] It is also advantageous if at least one of the upwardly extending cardboard surfaces is connected to the flattened bag surface by two linear connections arranged one above the other, with an opening line located between the two linear connections. The two linear connections are, in particular, linear adhesives. Alternatively, this can also be a weld, for example.

[0048] Preferably, there are two linear connections between each of the two flattened bag surfaces and the cardboard surfaces covering the flat bag surfaces.

[0049] Preferably, a closure seam of the bag is located above the opening line and particularly preferably at the level of the upper of the two linear connections. If the packaging is opened or severed at the opening line, the closure seam is preferably removed together with the upper linear connections. Then only the lower linear adhesives of the cardboard surfaces to the bag remain, and the cardboard surfaces can be moved apart. It is also advantageous if the bag has a first width and wherein at least one of the upwardly extending cardboard surfaces has, at least in some regions, a second width that is reduced compared to the first width.

[0050] Preferably, the base or the carton base is the same width as the bag, especially the first width. In some cases, the base may even be slightly wider.

[0051] The reduced width is preferably implemented in the area of ​​the upwardly extending cardboard surfaces so that, when viewed from one of these cardboard surfaces, lateral areas of the bag are visible.

[0052] In some design variants, the reduced second width can also be implemented in areas of the carton base, so that the cardboard sleeve is also narrower than the bag here. Therefore, the cardboard sleeve does not have to cover the entire bag width; it may be sufficient for the cardboard sleeve to cover only part of the bag width.

[0053] Also to be described here is a method for producing a package according to one of the preceding claims, comprising the following steps: a) providing a bag with a flattened shape having two opposing flattened bag surfaces containing a product; b) feeding a carton blank having a carton bottom surface and two carton surfaces which are connected to the carton bottom surface by first folding lines; c) folding the carton blank along the folding lines around the bag so that a carton sleeve is formed around the bag.

[0054] The cardboard sleeve of the described packaging is produced from the cardboard blank. Preferably, during production (particularly before or after step c)), the cardboard blank or the cardboard sleeve formed by the cardboard blank and the bag are connected or fastened to one another. Preferably, at least one permanent (particularly non-destructively detachable) connection is formed between the bag and the cardboard blank or the cardboard sleeve.

[0055] It should be noted that the particular advantages and design features described in connection with the packaging described above are also applicable and transferable to the process described below.

[0056] The process is particularly advantageous if the flattened shape of the bag is aligned horizontally during steps b) and c).

[0057] Particularly advantageously, vibrations of the bag can be used to distribute the product evenly. Once the cardboard sleeve is applied around the bag, the sleeve prevents unwanted deformation of the bag and any undesired changes in the product distribution within the bag.

[0058] In other embodiments of the method, it is advantageous if the flattened shape of the bag is oriented vertically during steps b) and c).

[0059] It is also advantageous if the carton blank is fed to the bag from below. This describes a relative movement of the carton blank to the bag. The bag can be moved downwards to bring it closer to the carton blank and / or the carton blank can be moved upwards.

[0060] The carton blank can be fed directly underneath the bag making machine, where the bags are filled with the product. The bag is preferably placed centrally on the carton blank.

[0061] One advantage of vertical feeding is that the bag is typically filled with product in a vertical orientation, aided by gravity. Typically, the bag hangs from one end during product filling. The bottom end of the bag is preferably already sealed with a seam.

[0062] For horizontal batch feeding, the bag must first be sealed at the top with a closing seam and can then be laid down. This horizontal batch allows the product to be leveled within the bag, ensuring even product distribution.

[0063] The method is further particularly advantageous if the folding of the cardboard blank in step c) is carried out by means of a folding box into which the cardboard blank is inserted, wherein the insertion assists folding of the cardboard blank along the first folding lines.

[0064] Another option for turning the cardboard blank into a cardboard sleeve is using a folding box, which can also be referred to as a cassette. In a first embodiment of the process, the cardboard blank is inserted into the folding box. In a second embodiment, the cardboard blank is placed on the folding box - in particular in such a way that the cardboard base surface covers an opening in the folding box. In the first embodiment, the bag is inserted into the folding box, in which the cardboard surfaces of the cardboard sleeve are already correctly positioned. In the second embodiment, the cardboard blank and the bag are pushed into the folding box together, and the cardboard surfaces of the cardboard sleeve are also aligned in the process.

[0065] The advantage of carrying out the process with a folding box is generally that the carton blank and the bag have a stable enclosure during the joining process, which reduces the joining tolerances of the two objects - especially when cardboard surfaces of the cardboard sleeve and the bag are glued together.

[0066] A particular advantage of producing the described packaging compared to producing packaging with a bag and a complete outer carton is that the cardboard sleeve can be folded around the bag. In contrast, when using a complete outer carton, it is necessary to insert the bag into the already folded outer carton. Applying the sleeve is much easier to integrate into a process for producing a filled package.

[0067] The invention and the technical context of the invention are explained in more detail below with reference to the figures. The figures show preferred embodiments to which the invention is not limited. It should be noted in particular that the figures, and in particular the proportions depicted in the figures, are only schematic. They show:

[0076] packaging; and

[0077] Fig. 9: a representation of a further embodiment of a described packaging.

[0078] Fig. 1 shows a package 1 consisting of a bag 2. The bag 2 is closed on both sides by a closure seam 30, for example, glued, welded, and / or folded, and it has two flattened bag surfaces 4, on which, for example, advertising images and / or product descriptions can be displayed. This type of bag cannot be placed upright in such a way that the flattened bag surface 4 with advertising images and / or product descriptions is clearly presented in a sales area. The package 1 shown in Fig. 1 is often also referred to as a "pillow bag."

[0079] In order to enable the presentation of advertising representations and / or product descriptions on a flattened bag surface, the packaging 1 according to Figs. 2a and 2b are known. In these packaging 1, the bag 2 has a glued, welded and / or folded closure seam 30 only on its upper side 18. On an underside, these bags 2 each have a base 6, which ensures that the bag can be placed upright so that the flattened bag surface 4 with advertising representations and / or product descriptions is clearly presented in a sales area. In the embodiment according to Fig. 2a, the bag 2 has a square cross-sectional shape and the base 6 is preferably formed by folded over areas of the bag 2. In the embodiment according to Fig. 2b, the base 6 is preferably formed by a base element glued or welded into the bag 2. Basically, the bottom surface elements shown in Figs.The embodiments of packaging 1 based on bags 2 shown in Figs. 2a and 2b are complex to manufacture. Additional work steps are required to create the bases 6. Furthermore, with these embodiments, it is often necessary to use a somewhat stronger material for the bag 2 itself, which provides sufficient mechanical stability for the bag 2 or packaging 1 to stand upright. The packaging 1 shown in Figs. 2a and 2b are often also referred to as block-bottom bags (stand-up pouches), 4-corner seal bags, Doy Bags, etc.

[0080] 3a to 3c show a sequence of a method for producing the packaging 1 described here, with a representation of the described packaging 1 in various process states. The packaging 1 described here is based on a bag 2, as also shown in Fig. 1, which would not be stable on its own. In step a), such a bag 2 is provided. In step b), a cardboard blank 26 is then fed, which has a cardboard base surface 5 and further cardboard surfaces 7 connected to the cardboard base surface 5 via first folding lines 8. Steps a) and b) are shown in Fig. 3a. Step c) is then shown in Fig. 3b. The cardboard blank 26 is bent over at the first folding lines 8, so that the cardboard surfaces 7 extend upwards from the cardboard base surface 5 and cover the flattened bag surfaces 4 of the bag 2. In Fig.Figure 3c then shows the packaging 1 described here, which was produced by the method. The cardboard blank 26 forms the cardboard sleeve 3, which surrounds the bag 2 and forms the bottom surface 2, with exposed lateral areas 9 of the bag 2 that are not covered by the cardboard sleeve 3.

[0081] Fig. 4a and 4b show two different variants for feeding a bag 2 to a carton blank 26. The type of feeding of the bag 2 can in particular control the distribution of the product 25 contained in the bag 2. Fig. 4a shows a vertical feed. Here, the bag 2 is arranged vertically and product 25 contained in the bag 2 tends to collect at one end of the bag 2. In this way, packages can be produced which tend to taper towards the top. Fig. 4b shows a horizontal feed, which tends to ensure that the product is evenly distributed in the bag 2. With this type of feed, packages can be produced whose cross-section is more uniform over its height.

[0082] Fig. 5a to 5c show a sequence of a special method for producing the described packaging with the aid of a folding box 27. The folding box 27 specifies an external dimension of the packaging to be produced. First, as shown in Fig. 5a, the cardboard blank 26 is placed with the cardboard base surface 5 on the folding box 27. The packaging 1 is then inserted into the folding box 27. This procedure can be seen in Figs. 5b and 5c. The cardboard blank 26 is folded along the first fold lines 8 and the cardboard surfaces 7 are placed against the bag 2 in such a way that they extend upwards.

[0083] Fig. 6 shows an embodiment of a described packaging 1, in which the bag 2 is attached to the cardboard base surface 5 with an adhesive connection 13. The adhesive connection 13 is indicated schematically here. It is located on an upper side of the cardboard base surface 5 and there connects the bag 2 to the cardboard base surface 5. In an upper region 21 there is an access area 19 through which a product 25 contained in the bag 2 can be removed from the bag 2. In the upper region 21, the bag 2 is connected to the cardboard surfaces 7 of the cardboard sleeve 3 by two adhesive connections 13 arranged one above the other and designed as linear connections 22.Between the linear connections 22 there is an opening line 20, at which the bag 2 and the cardboard sleeve 3 can be severed in order to open the bag 2, a closure seam 30 (not shown here) of the bag 2 is preferably located above the opening line 20 at the level of the upper linear connection 20. By removing the upper linear connection 20, a distance 17 between the cardboard surfaces 7 can be increased in order to open the access area 19 of the bag 2. In Fig. 6, the position 10 spaced from the standing surface 6 or the cardboard bottom surface 5 is also marked as an example, at which position the cardboard connecting webs 11 can be arranged, which will be explained in more detail below with reference to Figs. 7 and 8.7 shows a special cardboard blank 26 for forming a cardboard sleeve 3 for a written package 1 in an unfolded state. In addition, one of the cardboard surfaces 7 is adjoined by cardboard connecting webs 11, which are connected to the cardboard surface 7 via second folding lines 12 and which are each designed to be glued to the other cardboard surface 7 with an adhesive flap 29, thus connecting the two cardboard surfaces 7 to one another. The adhesive flaps 29 are connected to the cardboard connecting webs 11 via fourth folding lines 28. Each of the cardboard connecting webs 11 is itself further subdivided into cardboard web segments 16, so that the cardboard connecting webs 11 can be folded together at third folding lines 15 between the cardboard web segments 16.In this way, the upper edges of the cardboard surfaces 7 and the cardboard connecting webs 11 are arranged together to form a peripheral edge around an access area 19 of the packaging 1.

[0084] Fig. 8 shows a folding diagram in five individual steps, according to which the cardboard blank 26 shown in Fig. 7 is folded to form the cardboard sleeve 3 with the cardboard connecting webs 11. Also shown here are connections of the adhesive flaps 29 of the cardboard connecting webs 11 to the other cardboard surfaces 7, designed as plug connections 14 or adhesive connections 13.

[0085] Fig. 9 shows a variant of a described package 1, in which a second width 24 of the cardboard sleeve 3 is reduced in some areas compared to a first width 23 of the package 1 and in particular of the bag 2. If the bag 2 is made of a transparent material, this design allows the product 25 in the bag 2 to be visible from the side of the flattened bag surface 4. List of Reference Symbols
