Description

Packaging device

technical field

The invention relates to a packaging device for dimensionally instable objects having a cubic shape.

Background technique

Such shape-unstable objects mainly composed of fabric or fabric-like materials are flexible and can change their shape at will. A garment such as a pullover is mentioned as an example only, but could also be a blanket, for example. For storage purposes, but often also for sale purposes, ie when these objects are displayed in a store, these objects are usually folded or stacked together and have a cubic shape or have a shape that is at least approximately cubic. For example, the blanket is regularly folded into a cube shape, which is easy to achieve due to its regular rectangular shape. These objects (such as blankets) are usually not packaged, that is, although the blankets are stacked, these blankets can then be freely stacked, and in particular can be displayed individually or on top of each other in a store .

In principle, such objects, such as such blankets, can be placed in boxes, eg made of cardboard, in which the blankets are protected and which are easy to stack. Here, however, the problem is that the contents cannot be identified, ie it is not possible to see which blanket or which blanket pattern is contained. Tactile testing is also not possible. This is only possible with the box fully open, which is particularly difficult when the box is housed in a stack from which it must first be pulled.

Contents of the invention

The invention is therefore based on the problem of proposing a comparatively improved packaging device for such objects.

In order to solve the above-mentioned problems, the present invention proposes a packaging device for non-dimensionally stable objects having a cubic shape, the packaging device includes a sheet-like envelope made of flexible material, the envelope wraps around the object and will The object is wrapped on two sides, the overlapping ends of the envelope in the enclosing position can be connected to each other, and the packaging device has an outer packaging consisting of two packaging halves that are U-shaped in cross-section , the packaging halves are made of a harder material than the wrapper material, the packaging halves each have two side branches and a middle branch connecting the side branches together, wherein the opposite The packaging halves accommodate between them the object to be enclosed by the envelope and cover the object on four sides, two of which are the open sides of the envelope, and by means of which the packaging half The side branches overlap each other and can be connected to each other in the overlapping area, or the packaging halves are formed from rectangular packaging blanks on which a plurality of linear folding embossments are respectively provided in two longitudinal regions. The packaging blank can be folded along the fold embossing into a rectangle with four side branches, wherein two side branches overlapping each other can be connected to each other in the overlap region.

Thus, the packaging device according to the invention is two-part, consisting of an inner envelope and an outer outer wrapper which is stiffer than said inner envelope. The inner envelope is made of a flexible material, which is a correspondingly dimensioned rectangular sheet-shaped envelope, which is particularly preferably made of paper. The inner envelope is dimensioned such that it encloses the object on four sides (i.e. the bottom, two vertical sides and the top), i.e. in particular a blanket folded together in a cuboidal fashion can wrap the envelope around the object . Secure the two overlapping envelope ends relative to each other. That is, the object is enclosed at four sides, but the two opposite sides are open. In this case, the width of the envelope corresponds approximately to the width of the folded blanket or is slightly narrower.

The blanket wrapped in this way is then placed in the outer packaging. According to a first variant of the invention, the outer packaging itself consists of two U-shaped packaging halves in cross-section, said packaging halves being made of a significantly stiffer material than a flexible, preferably paper envelope, Preferably constructed of cardboard or a cardboard-like material. Each packing half is U-shaped, ie has a middle branch and two side branches adjoining the middle branch, which are at an angle of 90° to the middle branch at least in the packing position. To wrap, the wrapped blanket is inserted into one of the pack halves or placed over the middle branch of the pack half, then the side branches are wrapped up if they are not already vertically up. The upper packaging half is then placed such that the middle branches substantially enclose the lower packaging half and the side branches of the upper packaging half at least partially or completely cover the side branches of the lower packaging half. The corresponding overlapping side branches are then fixed relative to each other, so that the outer packaging is finally closed. In this case, the enveloped blanket is placed in the outer packaging such that the two open sides of the envelope are covered by adjacent side branches of the outer packaging, while the side closed by the envelope is visible on the open side of the outer packaging. As mentioned above, the envelope does not completely enclose the contained blanket at the sides or the blanket protrudes slightly at the edges so that, although the blanket is contained in the outer packaging, it is visible at least at the edges. That is, despite the blanket being packed, it is possible to recognize what pattern the blanket has or what color it is, and since the blanket is also slightly open, it is also possible to touch the blanket without taking it out. Of course, it is also possible in principle, after the outer packaging has been opened on both sides, to push the blanket together with the envelope out of the outer packaging, so that the two opened sides of the envelope are more easily accessible.

Thus, the packaging device according to the invention allows, on the one hand, to pack and thus protect cubic objects such as blankets, in particular folded together, but at the same time enables in a simple manner the identification of which blanket or blanket can be touched. blanket. In addition, the stable outer packaging also enables the possibility of stacking the packed blankets in an attractive manner and displaying them in the store, since orderly stacks can be created in which individual blankets can be identified , which is different from stacking blankets that are stacked together in sequence one after the other, resulting in an irregularly shaped, unstable stack.

Another particular advantage of the packaging device according to the invention is that it offers the possibility to pack objects or blankets stacked at different heights with the same packaging device. As mentioned above, the two packaging halves are positioned opposite each other such that the side branches of the two packaging halves overlap. In a blanket that is folded flat, the two packaging halves can be nested relatively broadly within one another, that is to say the two side branches overlap over a relatively large area, at most completely. In this case, the overall height of the outer packaging is relatively low. Furthermore, it is of course also possible to position the two packaging halves further apart from each other, so that the overlap is smaller, so that higher stacked objects or taller folded blankets can be inserted. Ultimately, the maximum package height is defined in such a way that in order to connect these side branches together, a minimum overlap must also be achieved. This means that objects of different heights can be packaged with the same packaging device or the same outer packaging, since the outer packaging itself is flexible with regard to its height.

According to a second variant of the invention, the outer packaging consists of a rectangular packaging blank on which a plurality of linear folded embossments are provided in two longitudinal regions respectively, said packaging blank being able to The folded embossing is folded into a rectangle with four side branches, wherein two side branches that overlap one another can be connected to one another in the overlap region. Here, instead of two packaging halves, only one packaging blank or folding blank of suitable size is used. The packaging blank is characterized in that, viewed in the longitudinal direction of the rectangular packaging blank, the packaging blank has in two longitudinal regions spaced apart from each other a plurality of linear, ie linear and extending transversely to the longitudinal direction, Fold embossments parallel to one another, ie defined fold lines, at which the packaging blank can be folded. This enables a total of five side branches to be folded, wherein the two end side branches overlap each other and can be fixed relative to each other. Multiple fold embossments, i.e. defined creases, are provided in each area so that, for example, a side branch forming the base can be folded, on either side of which a first even longer side branch adjoins each . Due to the multiple fold lines on both sides, it is again possible to fold only each side branch, resulting in two side branches forming the sides and two side branches forming the top, which overlap each other and can be joined together . In this case, the height of the two side branches forming the sides can vary, depending on which folding line the two end side branches are folded around. The shorter the two sides, the longer the two end side branches and the larger the overlapping area, and vice versa. The maximum height is determined by the two fold lines that are farthest from each other, and the minimum height is determined by the two fold lines that are closest to each other in the two regions. It is thus also possible in this very simple manner to produce outer packagings which are variable in height and which are adapted to the height of the objects to be enclosed.

The envelope itself is preferably made of paper, wherein, since the envelope is visible on the open side of the outer packaging, preferably a more stable thick paper can be used, of course, corresponding embossing can also be provided on the paper, as in Logos, brands or other images or descriptions, in which case these embossments are of course also visible. As an alternative, very thin, almost transparent, filamentary papers can also be used. The outer packaging is preferably made of cardboard, ie also paper based. The cardboard should have sufficient weight per unit area to make it sufficiently stable or rigid, so that the middle and side branches have sufficient inherent rigidity to wrap around objects stably and allow stacking. Of course, the outer packaging or the cardboard can also be printed accordingly, as already explained above for the envelope. Of course, since the cardboard as outer packaging is visible over a large area, ie at least the upper middle branch and the outer side branches are visible, large area printing, eg with a logo or any pattern, can be used.

The envelope and the outer packaging are particularly preferably made of recycled material, thus preferably recycled paper or cardboard, which is advantageous for sustainability reasons.

According to a particularly advantageous development of the invention of the first variant with two packaging halves, the side branches of the two packaging halves have the same height. As mentioned above, the side branches of the two packing halves overlap, wherein the degree of overlap is variable, depending on the height of the blanket to be accommodated. A maximum height variation exists if the two side branches have the same height, defined as the direction along which the outer packaging can vary in the degree of overlap. In the smallest packing position, the two side branches completely overlap, precisely because the two side branches have the same height. At maximum packing height, the two side branches are pulled apart as far as possible, leaving only the remaining overlap for connection. In this case, the receiving height corresponds roughly to twice the height of the side branches, minus the small remaining overlap. This configuration is also advantageous from a manufacturing technology point of view, since the two packaging halves ultimately consist of the same folded blank.

Furthermore, it is advantageous if the packaging halves have the same width. This shows that wrappers that wrap around on all four sides have the same width everywhere. This configuration is again advantageous from a manufacturing point of view, since the two folding blanks can again be of the same design, even if the side branches also have the same height.

Another alternative consists in that one packaging half is wider than the other packaging half. That is to say, in the packaging position, the one packaging half, i.e. for example the lower packaging half, is flush with the upper packaging half on one side, but protrudes beyond the upper packaging half on the other side, for example by a few centimeters , for example 5cm. The protruding portion is defined by a segmentally protruding middle branch and a segmentally protruding side branch. The protrusion generally forms a kind of support lug which is able to pull the inner object, ie the wrapped blanket, slightly out, but still rest it on the protrusion so that the blanket is not unsupported. This is advantageous for display purposes. For display purposes, for example, a blanket or the like can be pushed out of the outer packaging partly or as far as the protruding part in order to make the open side of the envelope more accessible.

According to a first variant, the two intermediate branches may have the same length. In this case, it is advantageous to use a thinner cardboard material, so that these side branches are not too thick. Because in this case these side branches can be placed on top of each other without any problem, even if the two packaging halves are pushed apart as far as possible, i.e. given the maximum degree of overlap in which the built-in side branches The two longitudinal ends of the package approximately rest on the middle branch of the other package half.

In the case of a correspondingly thicker cardboard material, a central branch of the one packaging half can in principle be shorter than the other central branch of the other packaging half by at least one single thickness of a lateral branch, in particular Is twice the thickness of the short side branch. The configuration according to the invention with central branches of different sizes enables compensation of the thickness of the side branches so that these side branches can also be superimposed over a large area without the outer side branches protruding.

As mentioned above, the wrapper is secured in the packaging position at the ends, ie the ends of the wrapper are secured relative to each other. The overlapping side branches are also fixed relative to each other. To this end, it is advantageous to provide at least one end of the envelope and at least one side branch of each packaging half, or on the side branches of only one or both packaging halves, for connecting the ends of the envelope or overlapping The side branches are joined together by connecting members. A corresponding fastening in the packaging position is achieved via these connecting elements. Adhesives are preferably used as such connecting means, i.e. for example on the envelope or on the corresponding side branches, the application of a correspondingly thinner adhesive is achieved, wherein the applied adhesive is preferably covered with a removable protective strip, Such as silicone paper. The adhesive or adhesive application is advantageously applied on the edge or edge side, respectively, in order to be able to pull apart to the greatest extent especially with regard to these side branches. However, in the case of envelopes, the adhesive can also be, for example, an adhesive strip bonded to the outside of the envelope, which protrudes at the edge and which is then glued to the adjacent envelope face.

If corresponding connecting means, in particular adhesives, are provided only on one end of the envelope or only on some side branches, it must be ensured that said envelope or said packaging halves are correctly aligned when placing the envelope and assembling the packaging halves , so that the connection member or the adhesive surface is correctly positioned and the connection member or the adhesive surface can be bonded to the counterpart part. In order to avoid relatively complicated alignments which may be associated with finding where the corresponding connecting elements are, a development of the invention proposes that at the two ends of the envelope and/or on the two lateral branches of each packaging half there are Connect components. In this configuration, it does not matter whether the envelope is folded from one side or from the other, or whether the side branches of one or the other packaging half are on the outside. In any case, suitable connecting means or in particular adhesives are provided in the region where the connection is to be made.

The length of the envelope itself can be, for example, 40-120cm, and the width is 20-50cm, while the width of the half of the package can be 12-40cm, wherein the length of the middle branch is 20-50cm, and the height of the side branches It is 5-15cm. In this case it is to be noted that, in the case of packaging, the envelope and the outer packaging are positioned in a manner rotated by 90° relative to each other. Both the envelope and the packaging halves have a rectangular basic shape when they lie flat. However, in the case of packaging, the width direction of the envelope extends in the length direction of the packaging halves and the length direction of the envelope extends in the width direction of the packaging halves. The width of the envelope thus ultimately corresponds to the length of the middle branch, which in turn corresponds ultimately to the width of the packaging halves and, of course, to the height of the side branches by which the height of the outer packaging is defined.

In a development of the invention with a one-piece or one-piece packaging blank according to the second variant of the invention, at least three, preferably at least four folded embossing. Of course, the formation of a correspondingly greater number of folding lines allows a greater variation in the height of the outer packaging since there are several folding planes on the packaging blank or folding blank.

Furthermore, it can be provided that a first longitudinal region is arranged adjacent to a longitudinal end and a second longitudinal region is arranged in the region of the longitudinal center of the packaging blank. This makes one of the two side branches overlapping each other significantly larger than the other, so that this side branch roughly forms the largest part of the visible roof, and is preferably partly to almost completely covered by the larger side branch (depending on the size of the outer packaging). height) the smaller side branches define only a smaller portion of the visible surface. Alternatively, the longitudinal regions can also be arranged symmetrically with respect to the longitudinal center of the folded blank.

In this case, at least one end of the envelope and at least one of the overlapping side branches may be provided with connecting means for connecting the overlapping side branches together. It is also possible to provide connecting members on both ends of the envelope and/or on the two side branches of the packaging blank. In this case, each connecting member is preferably an adhesive, which is preferably covered with a removable protective strip.

The envelope may have a length of 40-120 cm and a width of 20-50 cm, and the packaging blank may have a length of 80-160 cm and a width of 20-50 cm in the unfolded state.

detailed description

FIG. 1 shows a packaging device 1 according to the invention, which is capable of packaging dimensionally non-stable objects having a cubic shape. The packaging device comprises an envelope 2 made of a flexible material, preferably paper, wherein in particular recycled paper is used, which envelope has a rectangular shape and is curved. Since the envelope is flexible or consists in particular of paper, it can be wrapped around a cuboid object not shown in detail, in particular a folded blanket, so that it wraps around the blanket on four sides. At one end there is a connecting member 3 in the form of an adhesive 4 applied in particular by means of a removable protective paper, by means of which connecting member the wrapped envelope 2 can be fixed.

The packaging device 1 also comprises an outer packaging 5 consisting of a first packaging half 6 and a second packaging half 7 . The outer packaging 5 or packaging halves 6, 7 are made of a significantly more stable material than the flexible material of the envelope 2, preferably cardboard, wherein in turn recycled cardboard.

Each packing half has a middle branch 8,9 and two side branches 10,11. On the inside of the side branches 10 , 11 there is again a connecting element 12 , 13 , again preferably an adhesive 14 , 15 provided with a protective strip, which makes it possible to connect the side branches 10 , 11 overlapping each other in the packaging position. connected together, the packaging location will be explained below.

Since the packaging halves 6, 7 consist of sufficiently stable cardboard, the central branches 8, 9 and the lateral branches 10, 11 are quasi-stable in nature, these central and lateral branches only bend towards each other, which can be achieved by introducing corresponding The folding slots are defined so that the middle branches 8, 9 and the side branches 10, 11 are substantially at right angles with respect to each other.

FIG. 2 is a top view of, for example, the upper U-shaped packaging half 6 , which is however geometrically identical to the lower packaging half 7 . Here too, a rectangular blank is given, wherein FIG. 2 shows only the central branch 8 in plan view, the two side branches 10 extending vertically into the drawing plane. The middle branch has a length l and a width b, wherein the length l of the middle branch is between 20-50 cm and the width b is between 12-40 cm, wherein this width is also the same as the total width of the individual packaging halves 6 , 7 . Referring to Fig. 4, the side branches 10, 11 preferably both have the same height h, wherein the side branches have a height between 5-15 cm.

FIG. 3 is a side view showing the faces of the side branches 10 , 11 . It can be seen that the lateral branches 10, 11 are of the same size.

FIG. 4 is a front side view of the two packaging halves 6, 7, wherein the same geometry and dimensions of the packaging halves 6, 7 are also shown, and the figure also shows that the lateral branches 10, 11 are arranged on the inside respectively. Adhesive 14, 15 at the edges.

FIG. 5 is a top view of the envelope 2 . The envelope is also rectangular and has a length / for example in the range between 40-120 cm. The width b of the paper envelope 2 is, for example, in the range of 20-50 cm. The width b of the envelope 2 corresponds to the length l of the respective middle branch 8, 9, since the envelope 2 almost fills the free opening side of the outer packaging 5 in the packaging position, which will be described below. The length 1 of the envelope is dimensioned such that an object, such as a folded blanket, can be conveniently wrapped on all four circumferential sides and there is a sufficiently large area of overlap to attach the ends of the envelope by adhesive 4.

6-9 exemplarily illustrate the encapsulation process. An object 16 is shown having a quasi-cubic shape, here in the form of blankets 17 stacked on top of each other. The blanket has a corresponding height dimensioned such that it can be covered by the two side branches 10 , 11 while connecting them together. The width of blankets 17 stacked together is roughly equivalent to the width of envelope 4 .

For packaging, a blanket 17 is placed on the wrapper 2, as shown in FIG. 6 . The envelope 2 is then wrapped around the blanket 17 such that the blanket is surrounded by the envelope 2 on four circumferential sides. The envelope 2 is then joined with adhesive 4 in the region of its overlapping ends, here at the top side. As shown in Figure 5, the adhesive 4 preferably extends over the entire width. However, it is also possible to provide only partial adhesive points, or to provide adhesive labels protruding at the edges or the like.

In a next step as shown in FIG. 8 , the wrapped blanket 17 is placed on the middle branch 9 of the lower packaging half 7 . Two side branches 11, at which the blanket 17 is exposed, cover a part of the open side of the envelope 2, as shown in FIG. 7 . In the example shown, the stacked blanket 17 is higher than the side branches 11 , ie it protrudes beyond the lower packaging half 7 .

Then, see Figure 9, the upper packaging half 6 is placed. The upper middle branch 8 is placed on the blanket 17 or envelope 2 at the top side. Two side branches 10 extend vertically downward and overlap with two side branches 11 . The total height of the resulting overlapping lateral branches 10 , 11 corresponds to the height of the blanket 17 . Then, after removal of the protective strip, the two side branches 10 , 11 are glued by means of adhesive 14 to the side branch 10 covering the built-in side branch 11 , resulting in a stable outer packaging 5 .

Figure 10 shows a fully packaged object in perspective view. It can be seen that the envelope 2 is exposed at the front and rear open sides of the outer packaging 5 . That is, the blanket 17 can easily be pushed out slightly from the outer packaging 5 so that the blanket 17 can be seen at the open side of the envelope, ie from the side. The color or pattern of the blanket may be recognized, but the sense of touch or the like may also be checked manually.

Overall, a correspondingly stable packaging is provided which is structurally simple and also easy to handle. Especially due to the identical design of the packaging halves 6, 7 and the presence of adhesive 14, 15 on the two side branches 10, 11 respectively, it may not be necessary to ensure that a specific packaging half is in the top or bottom side to ensure adhesion. Since the corresponding adhesive is provided on both packaging halves and are of the same size, it is possible to place one packaging half on the top side and the other on the bottom side and vice versa .

Although in the example only one adhesive 4 is provided on the envelope 2, it is also possible to arrange the adhesive 4 on the opposite edge, so it is not necessary to ensure which edge the adhesive is on or which edge is on. on and which edge is pressed.

As mentioned above, the outer packaging is constructed of a sufficiently stable cardboard material, so that the outer packaging is also compressive since it has sufficient inherent rigidity. Referring to Fig. 11, a plurality of packaged objects can be stacked on, for example, a pallet 18 for transportation. Of course, for the purpose of displaying in a shop, a plurality of packaged objects can also be stacked on top of each other, or Multiple rows of parallel stacks are formed. Since a stable stack can be formed due to the inherent stability or shape stability of the outer packaging, the corresponding blanket can also be seen in it without problems or can also be pulled out slightly without disturbing the corresponding stack. The heap becomes unstable.

A particular advantage of the packaging device 1 according to the invention lies in its variability in height. This is because according to the invention two U-shaped packaging halves 6 , 7 are used which lie opposite each other or one packaging half joins the other packaging half by means of its side branches. As clearly shown in Figures 12-14, depending on how far the two package halves are generally pushed toward each other, the height may vary. Figure 12 roughly shows the lowest outer packaging height and thus the basic packaging height. Here, the lower packaging half 7 is inserted as far as possible into the upper packaging half 6 . That is to say, the side branch 11 is completely covered by the side branch 10 , which with its upper edge approximately rests on the middle branch 8 of the upper packaging half. The blanket 17 is correspondingly lower.

FIG. 13 shows a packaging variant in which the two packaging halves 6 , 7 are pulled apart further. That is to say that the blanket 17 is folded significantly higher than in the example according to FIG. 12 . It can be seen that the outer side branches 10 no longer completely overlap the inner side branches 11 , but only partially, still always achieving a sufficient degree of overlap.

Finally, FIG. 13 shows the packaging form in which the two packaging halves 6 , 7 are pulled apart to the greatest extent, that is to say the maximum packaging height is thus shown. The outer side branches 10 and the inner side branches 11 overlap only in the respective edge regions provided with the adhesive 14 , 15 , so that a branch connection via the adhesive 14 is still possible despite maximum pulling apart. The blanket 17 is here folded at its maximum height.

The envelope 2 used in the packaging according to Figures 12, 13 and 14 can always have the same length, that is to say the length of the envelope is dimensioned so that it can wrap the blanket folded in as small a manner as possible and in a Fold the blanket in the largest possible way. That is, despite the difference in blanket height, it is not necessarily necessary to use a correspondingly adapted envelope 2, but the same envelope 2 can be used, of course for lower blankets compared to taller blankets Wrapping is done in a way that further overlaps.

The geometry or dimensions of the outer packaging 5 and the geometry or dimensions of the envelope 2 can also be selected differently. Another example of packaging geometry is shown in FIG. 15 . In this figure, the outer packaging 5 is wider but lower in height, ie the middle branches 8, 9 are longer and the side branches 10, 11 are slightly shorter than in the embodiment according to Figs. 1-5. This is also just an example of a geometric shape, any other dimensions are of course possible. In this case, the dimensions can be chosen such that the Euro-pallets can be stacked optimally.

Finally, FIG. 16 shows an embodiment of a packaging device 1 which in turn has an envelope 2 of the type described above and an outer packaging 5 comprising a first packaging half 6 and a second packaging half 7, which facing each other in the same manner as described above. For example, the blanket 17 is in turn enclosed on four sides by means of an envelope, and this arrangement is then introduced into the outer packaging 5 . However, in this embodiment the two packaging halves 6, 7 are not identical. It can be seen that the lower packaging half 7 is wider than the upper packaging half 6 , ie the middle branch 9 and the side branches 11 are wider than the middle branch 8 and the side branches 10 . If the two packaging halves 6 , 7 are arranged flush on one side, the lower packaging half 7 protrudes beyond the upper packaging half 6 . Accordingly, corresponding protrusions 18 are produced which provide a kind of support for carrying the blanket 17 which has here been pulled out of the outer packaging 5 for display purposes. This allows for a better view of the blanket 17 since the sides are exposed and easily accessible, as shown in FIG. 17 .

Here, however, the side branches 10 , 11 also overlap in height, so that a corresponding height change as described in connection with FIGS. 12-14 is also possible in this embodiment.

Finally, FIG. 17 shows another variant of the two packaging halves 6 , 7 . In this case, each packaging half 6 , 7 is provided with connecting elements 12 , 13 only on one side branch 10 , 11 , ie adhesive 14 , 15 and cover strip. As shown in Figure 17, this configuration also allows the packaging halves 6, 7 to be used as identical components.

Figure 18 is a schematic view of a packaging blank 19 made of cardboard or relatively strong paper, which forms an outer packaging 5 according to a second variant of the invention. The packaging blank 19 is a one-piece folding blank which can be folded into a rectangle open on both sides, so that the objects contained in the envelope 2 are also visible here on both open sides. The above description regarding the envelope 2 , its design and the way it is placed around the object etc. also applies to the second variant of the invention, reference being made to the above description to avoid repetition.

The packaging blank 19 is rectangular in the unfolded state, with a length l and a width b. The width b is dimensioned such that the objects packed into the envelope end almost flush on both sides of the opening. The length l is dimensioned such that the side branch to be folded that forms the bottom corresponds to the width of the envelope 2 and all other side branches can be folded.

The packaging blank 19 has a plurality of fold embossments 20 arranged in two groups, ie defined fold lines, which are arranged in two longitudinal regions 21 spaced apart from one another. In this example, the longitudinal regions 21 are arranged offset from the longitudinal center. Here, each set of fold embossments 20 comprises four fold embossments 20a, 20b, 20c, 20d, ie four fold lines are defined. The packaging blank 19 can be folded at each of these fold lines in order to form a corresponding side branch. Such a fold embossment 20 can be produced in a simple manner by pressing into an outer packaging material such as cardboard. This packaging blank allows the manufacture of rectangular outer packages 5 of three different heights.

In the example shown in Figures 19 to 21, the packaging blank 19 is folded at the two inner fold embossments 20a closest to each other, so that a first side branch 22 is formed thereon, which forms the outer bottom of the package. That is, the packaging blank is folded along the right set of left fold embossments 20a and the left set of right fold embossments 20a.

Then, in the example according to FIG. 19 , the corresponding adjacent folded embossments 20b are folded so that on the one hand two side branches 23 , 24 are formed which form the two sides and on the other hand the two ends. The upper side branches 25, 26 can be seen to overlap and connect to each other when forming the roof. This connection is achieved by means of an adhesive 27 provided at the left end of the packaging blank 19 and covered by a removable protective strip. The folded overpack shown in Figure 19 has the lowest height hi.

In the example according to Fig. 20, the first side branch 22 is formed again by folding around the innermost fold embossment 20a, ie the dimensions of the bottom remain the same. The other side branches 23, 24 and 25, 26 are formed by folding around the fold embossing 20c. It can be seen that the two side branches 23 , 24 of height h2 are slightly higher than the example according to FIG. 19 , while the side branches 25 , 26 are slightly shorter, but still sufficiently overlap and adhere to each other.

In the example according to FIG. 21 , the first side branch 22 is formed again by folding around the fold embossment 20 a , but the side branches 23 , 24 and 25 , 26 are formed by folding around the outer fold embossment 20 d. Here, the side branches 23 , 24 have the greatest height h3 , while the side branches 25 , 26 are the shortest, but still overlap and adhere to each other.

Thus, with the same base and top lid dimensions, the height of the outer packaging 5 can be varied considerably by means of the one-piece packaging blank 19 , so that different object heights can be adapted by means of the packaging blank 19 .

Finally, FIG. 22 shows an example of another embodiment of a packaging blank 19 , in which two longitudinal regions 21 are arranged symmetrically about the longitudinal center of the rectangular packaging blank 19 . Here, each set of folding embossments 20 comprises six individual folding embossments 20a, 20b, 20c, 20d, 20e, 20f, allowing greater variability in the height of the folded outer package 5 . Here five different heights can be folded in the same way as described for FIGS. 18 to 21 .
