Description

Method for folding out a package and package

Technical Field

The present invention relates to a method for folding out a package from a single sheet of foldable material, wherein the foldable material comprises: a rectangular rear panel having adjacent rectangular rear left and right side panels; a rectangular top panel adjacent the rear panel, the rectangular top panel having adjacent square top left and right side panels; a lid panel adjacent to the top panel, the lid panel having adjacent lid left and right side panels; a rectangular bottom panel adjacent the rear panel, the rectangular bottom panel having adjacent polygonal bottom left and right side panels; and a front panel adjacent the bottom panel, the front panel having adjacent front left and right side panels, wherein the respective adjacent panel panels and all of the left and right side panels are integral with each other in the single sheet of foldable material.

Background

Product packages, particularly smoking article packages, are typically produced from a sheet of foldable material. The foldable material is then folded to form a container or box enclosing an interior cavity. Such containers or cartridges generally have the following disadvantages: before the foldable material can be folded into the shape of a container or box, the foldable material must be cut into a customized blank shape depending on the packaging format and shape. When cutting the foldable material, a certain amount of the foldable material is wasted because the foldable material is cut away. Then, after the package is set up by folding, a large amount of adhesive is required to ensure that certain panels of the package are secured and held together in order to provide a three-dimensional package exhibiting sufficient internal storage capacity and mechanical resistance for commercialization.

Thus, a major drawback of current collapsible containers or cases and packaging methods is the waste of material and the overall associated packaging costs.

Disclosure of Invention

It is therefore an object of the present invention to provide a method for folding a package which minimizes waste of raw materials and improves the package itself. Furthermore, it is an object of the present invention to provide a method for folding a package, which is easy to use, cost-effective and easy to integrate at a production site. Further, it is an object of the present invention to provide a package which can be produced in a cost-effective manner and which minimizes waste and adhesive use.

All of the panels, as well as the left and right side panels, are integral with each other in a single piece of foldable material. This means that all panels are composed of the same single piece of foldable material without any cut-outs or slits. Preferably, the single sheet of foldable material comprises a rectangular shape. As a specific example of a rectangular shape, a square shape is also possible. The front, rear, bottom and top panels and the lid panel describe certain areas of the single sheet of foldable material in terms of their final position/function in the finally constructed package after the foldable material is folded.

The package can be formed from a single piece of foldable material by folding without cutting a preferably rectangular shaped single piece of foldable material by folding the top and bottom side panels diagonally in step b) and by folding the triangularly folded bottom side panels under the respective front side panels in step c) to form the smaller triangles.

With this technique, the package can be formed from a single sheet of foldable material without any through holes in the corners. This is a major advantage, since the internal cavity contained in the package is now better protected from its external environment. In particular, the air circulation that would be allowed through the through holes in the corners is now prevented or at least significantly limited, only the material pores allowing the potential gas circulation through the foldable material.

Cutting waste is minimized due to the fact that the package can now be folded from a single sheet of material without any cut-out. It is even possible to cut a single piece of foldable material from a roll without any waste of cutting.

Another advantage of this package is that the lid formed by the lid panel, the lid left and right side panels, the top panel, and the top left and right side panels is connected not only to the rear panel, but also to the rear left and right panels, thereby acting as the sides of the package. This connection of the cover panel to the rear left and right side panels is achieved via the top left and right side panels. This connection allows the lid to be opened by rotating only 90 deg. towards the top. In the open state, a lid rotated only 90 ° reduces the visibility of the package interior from the rear side of the package. This is advantageous whenever a user of the package desires to protect the product contained therein from view by any third party.

Preferably, in step b), the bottom side panels and the top side panels are folded diagonally to the front.

In this way, it is particularly easy to fold the bottom side panels folded triangularly under the respective front side panels, as specified in step c) of the method. In this embodiment, the same folding process performed for the bottom side panel is also performed for the top side panel. The folding process of the top side panels differs from the folding process of the bottom side panels only in one point. In contrast to the bottom side panels, the top side panels are not folded under the front side panels, but under the lid side panels. In this embodiment, neither the lower corner nor the upper corner includes a through hole. This improves even further the protection of the product contained in the package.

Preferably, in step b), the bottom side panels are folded diagonally forward and the top side panels are folded diagonally rearward.

In this particular embodiment, the bottom side panels are folded in exactly the same way as described in the previous embodiment, creating lower corners without any through holes. However, the top side panels are folded diagonally to the rear. This results in an arrangement of the package wherein the lid left side panel and the lid right side panel are placed directly at the lid panel and in full area contact therewith. Therefore, when the cover is closed, the cover left and right side panels are not arranged to be in direct full contact with the front left and right side panels and the rear left and right side panels. This makes opening and closing of the lid easier, because the lid is more accessible to the consumer, in particular because it is not wrapped circumferentially around the package.

Preferably, in step b), the bottom side panel is folded diagonally towards the rear, and the foldable material further comprises a cover panel adjacent to the front panel, the cover panel being folded 90 ° towards the front.

In this embodiment, the cover panel may act as a first closure, in addition to the lid, thereby acting as a second closure. This means that if the consumer wants to close the package, the first step is to fold the cover panel, which has completely closed the opening at the top, 90 ° to the front. In a second step, the cover panel is folded over the cover panel so as to now completely cover the opening of the package.

This double closure of the cover panel and the lid improves the protection of the product contained in the package. It further limits third parties to the visibility of the product contained in the package.

Preferably, the cover panel, the cover side panel, the front panel and the front side panel have a rectangular shape.

The rectangular form of the panel is advantageous because it makes the overall form of the foldable material particularly easy to cut, as this results in an overall pure rectangular form of the single piece of foldable material. However, it is also conceivable that the cover panel, the cover side panel, the front panel and the front side panel have a shape deviating from a rectangular shape. In particular, the edges of each panel may be bevelled, or the panels may comprise recesses or flaps or any other desired shape.

In particular, the edge of the lid side panel opposite the top side panel slopes in a direction outward from the lid panel toward the respective top side panel, and the edge of the front side panel opposite the bottom side panel slopes away from the respective bottom side panel in a direction outward from the front panel at the same angle as the edge of the lid side panel.

By this embodiment it may resemble a standard cigarette pack in shape. Due to the same angle of the front side panels and the bottom side panels, it is still possible to cut a single piece of foldable material from a roll. Due to the inclined front side panels, the edges of the front side panels arranged at the opening of the package are positioned lower relative to the edges of the back side panels arranged at the opening. This creates a plane of the opening that is inclined towards the consumer. This gives the consumer the impression that the opening is inclined towards him, making it easier for the consumer to access the product contained in the package.

Preferably, the edge of the cover panel opposite the top panel is curved in a convex shape and the edge of the front panel opposite the bottom panel is curved in a concave shape having the same curvature as the convex edge of the cover panel.

The extent of the front panel is reduced in height due to the curved shape of the edge of the front panel opposite the bottom panel. In the fully folded state, the foldable material forms a package. In this fully folded state, the edge of the front panel opposite the bottom panel is arranged as the edge of the upper opening of the package. Due to the concave curved shape of this edge, the opening of the package is enlarged. This enlarged opening provides easier access to the product contained in the package. In this embodiment, the similarly shaped edge of the top panel that is curved in a convex shape ensures that the foldable material can still be cut from the roll. Furthermore, no cutting waste is generated and therefore is very effective in material use.

Preferably, the front panel has a cut-out at an edge of the front panel opposite the bottom panel.

The cut-out at the edge of the front panel opposite the bottom panel ensures even better access to the product contained in the package. Since the edge of the lid panel opposite the top panel preferably comprises a linear shape, in this embodiment the foldable material can be cut from the roll, although the area severed at the edge of the front panel opposite the bottom panel generates a minimum amount of waste.

Preferably the lid panel has an outwardly directed flap at an edge opposite the top panel and the front panel has a horizontal slit into which the flap can be inserted.

In the fully folded state of the foldable material forming the package, the cover flaps of the cover panels are now inserted into the horizontal slits of the front panel when the cover is closed. The lid sheet is inserted into the horizontal slit to secure the lid in the closed position. In this way unwanted opening of the package is prevented. This is very advantageous in that unnecessary air circulation between the interior cavity of the package and the surroundings of the package is at least reduced or even prevented.

In this embodiment, the foldable material can still be cut from the roll with a minimum of cutting waste. Depending on the choice of length and height of the coverslip, the amount of cutting waste can be minimized.

Preferably, the foldable material comprises a cover panel adjacent the front panel, the cover panel being folded 180 ° to the front.

Preferably, the cover panel has a longer extent in the longitudinal direction, since the cut is away from the edge of the front panel arranged at the opening. In this case, the longitudinal direction extends in a direction from the lid panel to the top panel and further to the rear, bottom and front panels of the single piece of foldable material lying on the surface. The described extent of the cover panel in the longitudinal direction ensures that the front panel is lined from the inside of the package when the cover panel is folded 180 ° forward. This lines the front panel and also lines the horizontal slits of the front panel. This reduces air circulation from the inside of the package to the outside thereof through the horizontal slits. Furthermore, the flap does not come into direct contact with the product placed in the package when inserted into the horizontal slit. This ensures that the flap does not damage the product contained in the package.

Preferably, at least a second foldable material (which may also be an internal stiffener) having a central panel of the same size or slightly smaller than the front panel of the first foldable material is inserted into the package, preferably parallel to the front panel, before step c).

The second foldable material preferably serves the same purpose as the covering panel. Additionally, the second sheet of foldable material may be more freely shaped as it is not necessarily cut from the same roll as the first sheet of foldable material. For example, the second piece of foldable material may receive a second cover panel in addition to the central panel, which may be folded 90 ° to the front. This second cover panel serves the same purpose as the previously mentioned cover panel to cover the product contained in the package when the lid is in the open state. This means that in order to access the product, the consumer must first open the cover and then fold the cover part back to its original position. This double closure of the package opening additionally protects the product contained in the package.

The second piece of foldable material may also be comprised of a different foldable material than the first piece of foldable material. For example, the second foldable material may have a higher stiffness than the first sheet of foldable material. The second piece of foldable material may then stabilize the package consisting of the first foldable material due to the higher stiffness. Such a stable package improves the protection of the product contained in the package.

Preferably, the foldable material is paper preferably having a weight of 70g/m2 to 130g/m 2.

The use of paper as the foldable material ensures a wide availability of the foldable material and a low cost of the produced package. The preferred weight of 70g/m2 to 130g/m2 ensures the necessary stability of the package in its fully folded and assembled form. This certain stability is necessary to protect the product contained in the package from being damaged or crushed. This is even more important when the package is carried in a pocket or handbag.

Preferably, the second foldable material is a sheet material. Preferably, the material of the inner reinforcement is a plate material.

The board has a higher stiffness than the paper. The use of a sheet as the second foldable material ensures that the second foldable material has an increased stiffness compared to the first foldable material, which is preferably made of paper. This embodiment ensures the stiffening properties of the second foldable material sheet.

A cutting pattern for cutting a foldable material that can be used for folding out a package according to the method of the invention is also conceivable.

The rectangle represents the most convenient shape to be cut from the roll, since only a horizontal cut perpendicular to the longitudinal extension of the web material is required. The cutting pattern may also include shapes that deviate slightly from rectangular shapes. For example, the cut pattern of the foldable material may comprise two at least partially curved edges parallel to each other. Preferably, the edges perpendicular to the longitudinal extension of the web are curved. This embodiment is also easy to cut from a reel with a curved cutting tool. With regard to the specific embodiment with curved edges, reference is made to the diagram of fig. 3 c). The cut pattern of the foldable material may alternatively comprise two at least partially angled edges at the edges opposite to each other. Preferably, the edges perpendicular to the longitudinal extension of the web are at least partially angled. This embodiment also facilitates cutting from the reel with an at least partially angled cutting tool. With respect to the specific embodiment with angled edges, reference is made to the diagrams of fig. 3b), 3h) and 3 i). It is also contemplated to use a rectangular cut pattern that includes v-shaped recesses at the bottom left and

right side panels

13, 14. The v-shaped recess comprises the size of one of the four triangles in which a square bottom left or bottom right panel would be separable.

The present invention may also include a package comprised of a foldable material and comprising a rectangular front panel, a rectangular rear panel, a rectangular bottom panel, and at least two layers of rectangular left and right side panels that collectively enclose an interior cavity of the package, wherein the package further comprises: a lid hingedly connected to the rear panel and capable of closing a top opening of the package with the lid; and four lower corners disposed between the lower edges of the front panel, the rear panel, the left and right side panels, and all edges of the bottom panel. The invention is characterized in that the foldable material completely closes the inner cavity without any through holes at all edges of the four lower corners and the bottom panel in the direction of the adjacent left and right side panels, front panel and rear panel.

The double layer nature of the side panels is achieved by arranging the front side panels on the rear side panels. The product contained in the internal cavity of the package or parts thereof cannot drip out of the package, since there are no through holes and the internal cavity is completely closed at all edges of the four lower corners and the bottom panel in the direction of the adjacent left and right side panels, front and rear panels. Furthermore, air flow between the interior cavity of the package and the external ambient environment is at least reduced or even completely prevented. This improves the freshness of the product contained in the package. Any risk of the product or parts of the product spilling out of the package is also reduced.

Preferably, the foldable material also completely encloses the interior cavity without any through-holes at all edges of the four upper corners and the top panel in the direction of the adjacent left and right side panels, the cover panel and the rear panel. This will even further reduce or even completely prevent air flow between the inner cavity of the package and the external ambient environment. Also, in this embodiment, the spill resistance of the package is further increased.

The present invention relates to a method for folding out a package from a single sheet of foldable material for packaging goods, wherein the foldable material comprises: a rectangular rear panel having adjacent rectangular rear left and right side panels; a rectangular top panel adjacent the rear panel, the rectangular top panel having adjacent square top left and right side panels; a lid panel adjacent the top panel, the lid panel having adjacent lid left and right side panels; a rectangular bottom panel adjacent the rear panel, the rectangular bottom panel having adjacent polygonal bottom left and right side panels; and a front panel adjacent the bottom panel, the front panel having adjacent front left and right side panels, wherein the respective adjacent panels and all of the left and right side panels are integral with each other in the single sheet of foldable material, the method comprising the steps of:

a) wrapping the packaged item in an inner liner;

b) placing internal reinforcements at least two adjacent sides of the wrapped packaged goods;

c) the foldable material is folded around the inner reinforcement and the wrapped packaged goods to form a package.

The invention may be combined with the embodiments described previously and/or the embodiments described below.

The packaged goods, preferably cigarette collations, are wrapped in an inner liner. The inner liner stabilizes the packaged goods, which may be composed of several individual articles, in an overall outer shape. This shape is preferably a cube. The cube shape may deviate from an ideal cube, particularly at the edges or corners, which may not be right angled, slightly rounded or otherwise deviate from an ideal cube. The inner liner is preferably composed of a thin and flexible material. As a result, the liner cannot correct the shape of and/or stabilize the packaged goods. The material is preferably paper or plastic foil. The paper may be coated, preferably with aluminium, or food grade polymer coated paper.

If such packaged goods wrapped in an inner liner should be packaged in a package folded out of a single sheet of foldable material, problems arise as to how to fold the foldable material into the desired shape at the high machine speeds used at current production sites. The use of internal stiffeners as folding supports is a possible solution to this problem. The internal reinforcement is placed at least two adjacent sides of the packaged goods that have been wrapped in the inner liner. Thereafter, the foldable material is folded around the packaged goods, which are wrapped in the inner liner and include internal reinforcements. In this step, the internal stiffeners act as folding supports for the foldable material. The package is folded around the packaged goods. This is in contrast to the following techniques: the packages are individually folded out without the packaged goods and the packaged goods are inserted into the complete package after the folding process. Folding the package around the packaged goods, wherein the packaged goods are stabilized with internal reinforcements, includes the advantage that folding of the folded material becomes easy. Due to the supporting properties of the internal reinforcements, the folds into the foldable material during the folding process become more sharp and precise. Moreover, production waste is reduced due to the more exact folding process with the internal stiffeners as folding supports. By using the internal stiffeners as folding supports for the foldable material, the folding method can be performed at the high machine speeds of prior art production machines. This means that the inner reinforcement makes it possible to realise the concept of a package folded around a packaged good on standard production machines.

The inner stiffener comprises at least two panels arranged at two adjacent sides of the packaged goods. Preferably, the inner reinforcement comprises at least a front panel and a top panel. The front panel and the top panel are arranged at the front side and the top side of the packaged goods. Preferably, the internal reinforcement is comprised of a thin but strong material. Preferably, the material is a sheet material. Preferably, the internal stiffener comprises a contact area with at least two sides of the packaged goods, which contact area extends over the entire surface of the internal stiffener directed towards the packaged goods.

According to another embodiment, the internal stiffeners are placed at least five adjacent sides of the wrapped packaged goods. The support characteristics of the internal reinforcement for the folded foldable material are further increased by covering at least five sides of the packaged goods, which are preferably wrapped in an inner liner. Preferably, the inner stiffener comprises at least five panels arranged at the side of the packaged goods. Preferably, the inner stiffener comprises contact areas with at least five sides of the packaged goods, which contact areas extend over the entire surface of the inner stiffener directed towards the packaged goods. Preferably, the internal reinforcement comprises at least a front panel, a top panel, a bottom panel and two side panels.

According to another embodiment, the inner reinforcement is attached to the inner liner at least one fixing point. Thus, the packaged goods together with the inner liner and the internal reinforcement become easier to handle. The unitized bundle of wrapped goods, liner and internal reinforcement can now be easily rotated and/or moved without risk of moving one of the bundle components relative to one of the other components.

According to another embodiment, the fixing point is located on an upper portion of the front panel of the internal stiffener, a top panel of the internal stiffener, a lower portion of the front panel of the internal stiffener, a bottom panel of the internal stiffener and/or at least one side panel of the internal stiffener. Preferably, the fixing point is located on the top panel of the inner stiffener. Preferably, the fixing point is located at the front section panel, preferably at an upper portion of the front panel. Preferably, the inner reinforcement is attached to the liner at more than one fixing point. In this case, at least one of the fixing points is preferably located at the top panel or at an upper portion of the front panel, wherein the other fixing points are located at the top panel, the front panel, the bottom panel and/or the side panels.

According to another embodiment, at least one additional fixing point is located between the foldable material and the inner reinforcement. With the additional fixing points between the foldable material and the inner stiffener, it is easy to position the foldable material during the folding process. The foldable material is fixed at the inner reinforcement. In particular, the fixing prevents or at least reduces any misalignment between the foldable material and the internal stiffener. This means that any displacement or sliding of the foldable material relative to the inner reinforcement is prevented or at least reduced. This ensures that all folds are correctly aligned with each other and with the packaged goods and/or the internal stiffeners.

According to another embodiment, the front panel of the inner stiffener comprises a perforation between the upper and lower portions of the inner stiffener and at the first opening of the assembled package, the top panel of the inner stiffener and the upper portion of the front panel being removable simultaneously with the upper portion of the liner. The perforations separate an upper portion of the front panel from a lower portion of the front panel. The upper portion of the front panel and the top panel of the internal stiffener are removable through the perforations. This means that after the top and front panel upper portions have been removed, the packaged goods can be accessed through the opening at the previous location of the top and front panel upper portions. By simultaneously removing the removable portion of the internal stiffener (i.e., the upper portions of the top and front panels) and the upper portion of the liner, the consumer has easy access to the packaged goods as compared to a situation where the consumer must first remove the removable portion of the internal stiffener and thereafter remove the upper portion of the liner. Preferably, this embodiment is combined with at least one fixing point between the top panel of the inner reinforcement and/or the upper part of the front panel. This makes it even easier to remove simultaneously.

The present invention also relates to a package comprised of a foldable material and comprising a rectangular front panel, a rectangular rear panel, a rectangular bottom panel, and at least two layers of rectangular left and right side panels collectively enclosing an interior cavity of the package, wherein the package further comprises: a lid hingedly connected to the rear panel and capable of closing a top opening of the package with the lid; and four lower corners disposed between the first edge of the front panel, the second edge of the rear panel, the third edges of the left and right side panels, and all edges of the bottom panel, wherein the foldable material completely encloses the interior cavity at the four lower corners and all edges of the bottom panel without any through-holes in the direction of the adjacent left and right side panels, front panels, and rear panels. The invention is characterized in that the package further comprises an inner liner and an inner reinforcement consisting of at least a front panel and a top panel.

The term package herein refers to a package obtained by the method according to at least claim 1. Due to the combination of the foldable material with the inner liner and the internal stiffener, the package exhibits excellent manufacturing qualities as previously indicated in relation to the manufacturing method.

According to another embodiment, the foldable material has a thickness of at least 0.08mm, preferably 0.09mm, even more preferably 0.1mm and/or a maximum thickness of 0.3mm, preferably 0.25mm, even more preferably 0.2 mm. Preferably, the thickness of the foldable material is between 0.08mm and 0.3mm, more preferably between 0.09mm and 0.25mm and most preferably between 0.1mm and 0.2 mm. Due to the supporting properties of the internal stiffeners during the folding process, only such a low thickness of the foldable material is possible. Furthermore, the given thickness range ensures proper machine running characteristics of the foldable material. With the mentioned thickness range it is possible to achieve sufficient folding quality at the highest manufacturing speed. In case of too high a thickness, the foldable material will require higher force to fold. Also, the crease will become less accurate. Below the optimal thickness, the foldable material will not be foldable with sufficient quality, as the material will become very flexible and less foldable.

According to another embodiment, the foldable material comprises a weight of at least 80gsm (grams per square meter), preferably 100gsm, even more preferably 120gsm and/or a maximum weight of 240gsm, preferably 210gsm, even more preferably 180 gsm. Preferably, the foldable material comprises a weight of between 80gsm and 240gsm, more preferably between 100gsm and 210gsm and most preferably between 120gsm and 180 gsm. This weight also affects machine running characteristics and folding quality. The ranges given ensure good machine running characteristics and high folding quality. This means that the manufacturing process can be performed at the highest speed.

According to another embodiment, at least one additional fixing point is located between the inner reinforcement and the foldable material. As already indicated, this fixing of the foldable material at the inner reinforcement improves the handling properties of the packaged goods and the inner liner and the inner reinforcement during the folding process.

According to another embodiment, the additional fixing points are arranged at the lower part of the front panel, the bottom panel and/or the side panels of the internal reinforcement. The additional fixing points at these locations ensure a good fixing of the foldable material at the internal reinforcement without damaging the internal reinforcement and/or the removable parts of the lining.

Fig. 2a) to 2h) show different steps for folding the package 1 with a sheet of foldable material 2. Fig. 2a) depicts a piece of foldable material 2 lying flat on a surface. In a first step all the

side panels

16, 13, 4, 7, 10, 17, 14, 5, 8, 11 are folded 90 ° forward with respect to the lid panel 9, the top panel 6, the rear panel 3, the bottom panel 12 and the front panel 15. This creates a first fold along the

second edges

16b, 13b, 4b, 7b, 10b of all the

left side panels

16, 13, 4, 7, 10. A second crease is also created along the

fourth edges

17d, 14d, 5d, 8d, 11d of all

right side panels

17, 14, 5, 8, 11.

In the next step, depicted in fig. 2c), the

top panels

6, 7, 8 are folded 90 ° forward with respect to the rear panel 3. This creates an additional crease along the third edge 6c of the top panel 6. In addition to this, the

top side panels

7, 8 are folded diagonally to form a triangle each. This results in two diagonal creases 7e, 8e extending along a linear connecting line from the second corner 72 to the fourth corner 74 of the top left side panel 7 and a linear connecting line from the first corner 81 to the third corner 83 of the top right side panel 8. For the top left panel 7 this means that the first corner 71 is placed on the third corner 73. It also means that the first edge 7a is placed on the fourth edge 7d and the second edge 7b is placed on the third edge 7 c. For the top right panel 8, this means that the second corner 82 is placed on the fourth corner 84. It also means that the first edge 8a is placed on the second edge 8b and the third edge 8c is placed on the fourth edge 8 d.

In the next step depicted in fig. 2d), the

bottom panels

12, 13, 14 are folded 90 ° forward with respect to the rear panel 3. This creates an additional crease along the fourth edge 12a of the bottom panel 12. In addition to this, the

bottom side panels

13, 14 are folded diagonally to each form a triangle. This results in two

diagonal creases

13e, 14e that extend along a linear connecting line from the first corner 131 to the third corner 133 of the bottom left side panel 13 and a linear connecting line from the second corner 142 to the fourth corner 144 of the bottom right side panel 14. For the bottom left panel 13, this means that the second corner 132 is placed on the fourth corner 134. It also means that the first edge 13a is placed on the second edge 13b and the third edge 13c is placed on the fourth edge 13 d. For the bottom right panel 14 this means that the first corner 141 is placed on the third corner 143. It also means that the first edge 14a is placed on the fourth edge 14d and the second edge 14b is placed on the third edge 14 c.

In step e), the

front panel

15, 16, 17 is folded 90 ° forward with respect to the

bottom panel

12, 13, 14. This creates a crease along the

first edge

15a, 16a, 17a of the

front panel

15, 16, 17. In the next step depicted in fig. 2f), the

bottom side panels

13, 14 folded triangularly are folded under the respective

front side panels

16, 17, forming a smaller triangle. For the bottom left panel 13, this operation places the third edge 13c on the second edge 13b and the third corner 133 on the first corner 131. For the bottom right panel 14, this operation places the third edge 14c on the fourth edge 14d and the second corner 142 on the fourth corner 144. In this arrangement, the respective

diagonal fold

13e, 14e is folded under the respective

front side panel

16, 17. This folding operation is accompanied by folding the

front side panels

16, 17 by 90 ° towards the front, so as to arrange the respective

front side panels

16, 17 on the respective

rear side panels

4, 5. At this stage, the twice diagonally folded

bottom side panels

13, 14 are arranged between the respective

rear side panels

4, 5 and the respective

front side panels

16, 17. In order to better secure the package, it is possible to secure the two

front side panels

16, 17 to the respective

rear side panels

4, 5.

The same operation is now performed on the

cover panels

9, 10, 11. This is depicted in fig. 2g) and 2 h). First, the

cover panel

9, 10, 11 is folded 90 ° to the front, thereby creating a crease along the

third edge

9c, 10c, 11 c. The triangularly folded

top side panels

7, 8 are folded under the respective

lid side panels

10, 11, forming a smaller triangle. For the top left panel 7, this operation places the first edge 7a on the second edge 7b and the second corner 72 on the fourth corner 74. For the top right panel 8, this operation places the first edge 8a on the fourth edge 8d and the first corner 81 on the third corner 83. In this arrangement, the respective diagonal fold 7e, 8e is folded under the respective

lid side panel

10, 11. This folding operation is accompanied by folding the

cover side panels

10, 11 by 90 ° towards the front, so as to arrange the respective

cover side panels

10, 11 on the respective

front side panels

16, 17. At this stage, the twice diagonally folded

top side panels

7, 8 are arranged between the respective

front side panels

16, 17 and the respective

lid side panels

10, 11. At this point, the package 1 is fully assembled.

As an alternative to the previously described folding operation, all

top panels

6, 7, 8 and all

lid panels

9, 10, 11 may be folded according to fig. 2i) to 2 k). The

bottom panels

12, 13, 14 and the

front panels

15, 16, 17 are folded as previously described. Only the folding operations of the

top panels

6, 7, 8 and the

lid panels

9, 10, 11 are different. Fig. 2i) depicts the starting position of this alternative folding method. In the next step depicted in fig. 2j), the lid left side panel 10 and the lid right side panel 11 are folded 180 ° forward so that they are arranged on the lid panel 9. For better fixation, the lid left side panel 10 and the lid right side panel 11 may be glued to the lid panel 9. This folding step is accompanied by the fourth corner 74 of the top left side panel 7 and the first corner 81 of the top left side panel 8 moving inwardly toward the corner of the first edge 6a of the top panel 6. In a next step, the top panel 6 is folded 90 ° forward with respect to the rear panel 3. This places the first corner 71 of the top left side panel 7 on the third corner 73 and the fourth corner 84 of the top right side panel on the second corner 82. Besides, it arranges the first edge 7a of the top left panel on the fourth edge 7d, the second edge 7b on the third edge 7c, and for the top right panel 8, the first edge 8a on the second edge 8b and the third edge 8c on the fourth edge 8 d. This means that the top left side panel 7 and the top right side panel 8 are folded diagonally rearward.

As a final step depicted in fig. 2k), the lid panel 9 is folded 90 ° to the front, together with the lid left side panel 10 and the lid right side panel 11. This places the cover panel 9 on the front panel 15. The

cover side panels

10, 11 are arranged between the front panel 15 and the cover panel 9. At this point, the package 1 is fully assembled.

In fig. 3a) to 3i), different embodiments of a single sheet of foldable material 2 are depicted. The respective figures show a single piece of foldable material 2 according to a particular cutting pattern of the respective embodiment and a completely assembled package 1 folded out with the respective single piece of foldable material 2.

Fig. 3a) shows a very simple embodiment of a single piece of foldable material 2. The first edge 2a and the third edge 2c of the single piece of foldable material 2 are completely linear. This results in horizontally arranged

edges

9a, 10a, 11a of the lid on the package 1 consisting of the lid panel 9 and the lid left 10 and right 11 side panels. The

edges

15c, 16c, 17c of the front panel 15 and the front left and

right side panels

16, 17 are also arranged horizontally on the package 1. The cover panel 9 and the cover left and

right side panels

10 and 11 overlap the front panel 15 and the front left and

right side panels

16 and 17. In this way, the package is completely closed.

Fig. 3b) shows an embodiment in which the

first edges

10a, 11a of the lid left side panel 10 and the lid right side panel 11 are angled. The first edge 10a of the lid left side panel 10 is angled towards the fourth corner 74 of the top left side panel 7. This makes the second edge 10b longer than the fourth edge 10d of the top left side panel 7. The first edge 11a of the top right side panel 11 is angled toward the first corner 81 of the top right side panel 81. This makes the second edge 11b shorter than the fourth edge 11d of the top right side panel 11.

In this embodiment, the

third edges

16c, 17c of the front left and

right side panels

16, 17 are also angled. The third edge 16c of the front left side panel 16 is angled away from the third corner 133 of the bottom left side panel 13. This makes the second edge 16b shorter than the fourth edge 16d of the front left side panel 16. The third edge 17c of the front right side panel 17 is angled away from the second corner 142 of the bottom right side panel 14. This makes the second edge 17b longer than the fourth edge 17d of the front left side panel. This overall shape of the single sheet of foldable material 2 creates in the fully assembled package 1 an angled arrangement of the first edge 9a of the horizontally arranged lid panel 9 and the third edge 15c of the front panel 15 and the

first edges

10a, 11a of the lid left and

right side panels

10, 11 and the

third edges

16c, 17c of the front left and

right side panels

16, 17.

Fig. 3c) shows an embodiment where the first edge 9a of the cover panel 9 is curved in a convex shape and the third edge 15c of the front panel 15 is curved in a complementary concave shape. This results in a curved first edge 9a of the lid panel 9 and third edge 15c of the front panel 15 in the fully assembled package 1.

Fig. 3d) shows an embodiment where the single piece of foldable material 2 comprises an additional cover panel 18, which arranges their

first edges

18a, 19a, 20a to the respective

third edges

15c, 16c, 17c of the front panel 15 and the

front side panels

16, 17, and a cover left side panel 19 and a cover right side panel 20. The cover panel 9 and the

cover side panels

10, 11 are slightly shorter to the extent that they are parallel to the longitudinal direction L. In the fully assembled package 1, the

bottom side panels

13, 14 have been folded diagonally to the rear. The

front side panels

16, 17 are covered by the

rear side panels

4, 5. The

cover side panels

19, 20 have been folded diagonally to the rear. Cover panel 18 has been folded 90 deg. towards the front. This means that in the folded and closed state of the package 1, the diagonally folded

cover panels

19, 20 are arranged below the cover panels 20. Cover panel 18 and cover

side panels

19, 20 serve as a first closure of package 1, with cover panel 9 and cover

side panels

10, 11 serving as a second closure of package 1.

Fig. 3e) depicts an embodiment comprising a cut-out 150 at the front panel 15. This creates a recess of the third edge 15 c. Preferably, the cut-out 150 comprises two recessed

portions

151, 153 arranged parallel to the longitudinal direction L and a horizontal portion 152 arranged perpendicular to the longitudinal direction L. The two recessed portions together with the horizontal portion form a generally rectangular recess of the third edge 15c of the front panel 15, which recess forms a cutout 150. Preferably, the generally rectangular shape of the cutout 150 includes rounded corners between the transitions from the recessed

portions

151, 153 to the horizontal portion 152 and also at the transition of the remaining horizontally disposed portion of the third edge 15c of the front panel 15. The package 1 now comprises a cut-out 150 in the front panel 15, which can be completely covered with the lid panel 9 in the fully assembled and closed state of the package 1.

Fig. 3f) shows another embodiment of a single sheet of foldable material 2. The single sheet of foldable material 2 comprises an outwardly directed flap 21 arranged at the first edge 9a of the lid panel 9. It further comprises a horizontal slit 22 in the front panel 15 into which the flap 21 can be inserted. In addition, the foldable material 2 comprises a cover panel 23 and adjacent

cover side panels

24, 25. The cover panel 13 is folded 180 ° forward so that it lines the front panel 15 from the inside of the package 1. The extent of the cover panel 23 in the longitudinal direction L is preferably longer than the distance between the slit 22 and the third edge 15c of the front panel 15.

The

cover side panels

24, 25 may be omitted entirely. Alternatively, the respective slits may be arranged at

first edges

24a, 25a of the cover side panels where they are directly adjacent to the

front side panels

16, 17. The

cover side panels

24, 25 may then be folded 180 ° forward. This creates an arrangement of

cover side panels

24, 25 in the package 1 between the front panel 15 and the cover panel 23.

Fig. 3g) depicts an embodiment of the foldable material 2 with an internal reinforcement 26, also referred to as additional second piece of foldable material 26. In this embodiment, the internal stiffener 26 comprises a front panel 27, a left side panel 28 and a right side panel 29, wherein the

side panels

28, 29 may be omitted, both

side panels

28, 29 being folded 90 ° with respect to the front panel 27. The internal reinforcement 26 may also include a top panel 30. The top panel 30 is folded 90 deg. in the same direction as the

side panels

28, 29. As described below, with reference to fig. 4-6, the internal stiffeners act as folding supports for the foldable material. The complete package folded out of foldable material (in one embodiment, depicted on the right-most side in fig. 3g) comprises internal stiffeners inside the package 1. The front panel 27 lines the front panel 15 with the slits 22 from the inside of the package 1. Top panel 30 and

side panels

28, 29 may serve as a first closure of package 1, with lid panel 9 and

lid side panels

10, 11 serving as a second closure of package 1. Alternatively, the inner reinforcement 26 may include perforations 300. The perforations 300 divide the front panel 27 into an upper portion 27a and a lower portion 27 b. At perforations 300, upper portion 27a may be separated from lower portion 27 b. Preferably, the upper portion 27a can be separated from the lower portion 27b by tearing the upper portion 27a away from the lower portion at the perforations 300. Together with the upper portion 27a, the top panel 30 is separated from the lower portion 27b of the front panel 27. The outer portion 300a of the perforation 300 is located at the edge between the front panel 27 and the top panel 30, seen transversely to the longitudinal portion L. The central portion 300b is positioned parallel to the edge between the front panel 27 and the top panel 30, but displaced towards the center of the front panel 27. The outer portion 300a and the central portion 300b of the perforation 300 are connected via two longitudinal portions 300 c. The longitudinal portion 300c is aligned parallel to the longitudinal direction L. The longitudinal portion 300c is aligned perpendicular to the outer portion 300a and the central portion 300 b. Along the edge between the front panel 27 and the top panel 30 seen perpendicular to the longitudinal direction L, a first outer portion 300a parallel to the longitudinal direction L is followed by a first longitudinal portion 300c parallel to the longitudinal direction L, then followed by a central portion 300b perpendicular to the longitudinal direction L, followed by a second longitudinal portion 300c and finally by another outer portion 300 a. The corners between the outer portion 300a and the longitudinal portion 300c and/or between the central portion 300b and the longitudinal portion 300c may be rounded. In other words, the perforations 300 form a recess from the edge between the front panel 27 and the top panel 30 towards the center of the front panel 27.

Fig. 3h) shows another embodiment. The fourth edge 10d of the lid left side panel 10 is inclined toward the first edge 9a of the lid panel 9. The second edge 11b of the lid right side panel 11 is inclined toward the first edge 9a of the lid panel 9. The corner between the fourth edge 10d and the first edge 10a of the left side panel 10 of the cover is rounded. The corner between the first edge 11a and the second edge 11b of the cover right side panel 11 is rounded. The foldable material 2 also comprises a lining panel 33, which is folded 180 ° forward. In this position, the liner panel 33 lines the lid panel 9 from the interior of the package 1, thereby stabilizing the lid panel 9.

The lid panel 9 further comprises a flap 21 directly adjacent the first edge 9a of the lid panel 9. The edge 21a of the lid sheet is cut, while the part of the first edge 9a which is arranged adjacent to the lid sheet 21 in a direction perpendicular to the longitudinal direction L is not cut but creased.

The cover panel 9 comprises an additional crease 9e arranged in the middle of the cover panel 9 perpendicular to the longitudinal direction L, which extends through the cover panel 9 from the fourth edge 10d of the cover left side panel 10 up to the second edge 11b of the cover right side panel 11 perpendicular to the longitudinal direction L. This crease makes it easier to insert the flap 21 into the slit 22.

The slits 22 may not be a simple cut of the foldable material 2 but include an extent in the longitudinal direction L. This means that a certain area of the front panel 15 is completely cut away. This makes it easier to insert the cover sheet 21 into the slit 22.

Fig. 3i) shows another embodiment of the foldable material 2. The

front side panels

16, 17 include angled

third edges

16c, 17 c. The

third edges

16c, 17c are inclined in the same way as described in the description of fig. 3 b). The

first edges

10a, 11a of the

cover side panels

10, 11 are also inclined. Their inclination is greater and/or the extent of the

side panels

10, 11 in the longitudinal direction L is smaller, so that the fourth edge 10d of the lid left side panel 10 and the second edge 11b of the lid right side panel 11 are completely omitted. This means that the

lid side panels

10, 11 comprise a triangular shape.

Preferably, the extent of the cover panel 9 in the longitudinal direction L is slightly longer than the extent of the

cover side panels

10, 11. Preferably, the corners at the beginning and end of the first edge 9a of the cover panel 9 are rounded. The foldable material may also comprise a liner panel 33 directly adjacent the first edge 9a of the lid panel 9. The two corners of the lining panel, which are arranged directly at the first edge 9a of the lid panel 9, may also be rounded. Preferably, all edges are rounded with the same curvature.

Fig. 3h) and 3i) also show an embodiment of the internal stiffener 26. The internal reinforcement 26 includes a bottom panel 31. The bottom panel 31 may be arranged to line the bottom panel 12 from the inside of the package 1. This further stabilizes the package 1. The bottom panel further eases the folding process of the foldable material 2 when it is folded around the packaged goods 100. The internal stiffener 26 may also include a recess 32 in the top panel 30. This recess 32 allows the simpler opening of the top panel 30 to act as a first closure of the package 1 or, in combination with the perforation 300, allows the consumer to more easily grasp the top panel to remove the top panel 30 and the upper portion 27a of the front panel 27 and preferably also the upper portion 202 of the liner 200.

The inner reinforcement 26 may also comprise fixing points 301, 302 at which the inner reinforcement 26 is attached to the liner 200 and/or the foldable material 2. In order to attach the inner stiffener 26 to the liner 200, the fixing points 301 are located on the side of the inner stiffener 26 facing the inside of the package 1 and facing the inner stiffener 26. To attach the foldable material 2 to the inner stiffener 26, additional fixing points 302 are located on the side of the inner stiffener 26 facing towards the outside of the package 1 and towards the foldable material 2. In this case, the fixing points are preferably located on the lower portion 27b of the front panel 27, on one or both

side panels

28, 29 and/or on the bottom panel 31. The fixing points 301, 302 are preferably located at the top panel 30, the upper portion 27a of the front panel 27, the lower portion 27b of the front panel 27, the bottom panel and/or one or both

side panels

28, 29. Preferably, the fixing points 301, 302 are located at the center of the respective panel or portion. In the alternative where the fixing point 301 is located at the centre of the top panel 30, the top panel 30 may comprise two fixing points 301 located to the left and right of the recess 32 on the top panel 30.

Fig. 4 shows a packaged article 100. In this embodiment, the packaged article 100 is a collation cigarette. The packaged article 100 includes a cube shape 101. The longest axis 102 of the cube shape 101 is aligned parallel to the longitudinal axis L.

Fig. 5 shows the packaged article 100 wrapped in the liner 200. The liner 200 completely covers the packaged goods 100. The liner 200 includes a removable upper portion 202 that is separable from the remainder 201 of the liner 200 at perforations 203. The packaged article 100 wrapped in the liner 200 comprises a cuboid shape comprising front and rear sides 200a, 200f, bottom and

top sides

200c, 200e and two

side surfaces

200b, 200 d.

After the packaged goods 100 have been wrapped in the liner 200, the internal stiffeners 26 are placed at the top side 200a, top and bottom sides 200c, and two sides 200b of the liner 200 in which the packaged goods 100 are wrapped. For clarity, the inner reinforcement 26 is depicted in fig. 6 as being slightly displaced from the liner. When placed at the liner 200, the front panel 27 of the liner is in contact with the front side 200a of the liner 200. Further, the top panel 30 of the inner reinforcement 27 is in contact with the top side 200e of the liner 200. The bottom panel 31 is in contact with the bottom side 200 c. The

side panels

28, 29 are in contact with the

respective sides

200b, 200 d. Preferably, all the interfaces between the internal reinforcement 26 and the lining 200 extend over the respective

entire panels

27, 28, 29, 30, 31 of the internal reinforcement 26. The upper portion 27a of the inner reinforcement 26 is in contact with the upper portion 202 of the liner 200. The top panel 30 of the internal stiffener 26 is attached at fixing points 301 to the upper portion 202, which is part of the top side 200e of the liner 200. Additionally, the upper portion 27a of the inner stiffener 26 may be attached to the upper portion 202 at the fixation point 301, which is part of the front side 200a of the liner 200. The packaged goods wrapped in the liner 200 with the internal reinforcement 26 disposed thereon are now further wrapped in the foldable material 2. The foldable material 2 is folded around the packaged goods 100 comprised in the inner liner 200 and the inner reinforcement 26.

The folding process may be performed as previously described (with reference to fig. 2a to 2 k). Alternatively, a foldable material 2 according to fig. 7 may be used. Figure 7 shows two embodiments of the foldable material 2 comprising the same modified features as compared to the embodiments of the foldable material 2 shown in figures 3h and 3 i. The bottom left side panel 13 and the bottom right side panel 14 include a polygonal shape 400. The polygonal shape 400 is composed of the outer edges of three identical right-angled triangles 400a to 400 c. The three triangles 400a to 400c are arranged in a manner to each other with the right-angled corners at the same point 404, the hypotenuses 13a to 13c, 14a to 14c of the triangles 400a to 400c are arranged perpendicular to the respective adjacent triangles 400a to 400c, and the

catheti

401, 402 of two adjacent triangles 400a to 400c facing each other are aligned with each other. Accordingly, this polygonal shape 400 includes v-shaped recesses 403 of the same shape as the triangles 400a to 400 c. Compared to the square shape, the package 1 folded out of the foldable material 2 with the polygonal bottom left side panel 13 and the bottom right side panel 14 has one less layer of material in the area where the polygonal bottom left side panel 13 and the bottom right side panel 14 are arranged in the folded state. This makes the package 1 less bulky. This improves the visible appearance of the exterior of the package 1. The folded bottom left and

right side panels

13, 14 are also prevented from extending into the interior of the package and occupying any space dedicated to packaging the article of merchandise 100.

In a first step of the folding process, as already depicted in fig. 2c, all

side panels

16, 13, 4, 7, 10, 17, 14, 5, 8, 11 are folded 90 ° forward with respect to the lid panel 9, the top panel 6, the rear panel 3, the bottom panel 12 and the front panel 15. In a second step, as already depicted in fig. 2c, the

top panels

6, 7, 8 are folded 90 ° forward with respect to the rear panel 3. In this step, a second triangle 400b comprising the

second edges

13b, 14b as hypotenuses is simultaneously folded forward over a first triangle 400a comprising the

first edges

13a, 14a as hypotenuses, thereby creating a crease at the coinciding catheti 401 of the first and

second triangles

400a, 400 b. In this folding step, the

first edges

13a, 14a are placed on the

second edges

13b, 14 b. In the next step, the first triangle 400a together with the second triangle 400b is folded 90 degrees onto the rear left and

right side panels

4, 5 along the now coinciding first and

second edges

13a, 13b, 14a, 14 b. In a fourth step, a third triangle comprising the

third edges

13c, 14c as hypotenuse is folded 180 degrees onto the second triangle 400b, wherein the

third edges

13c, 14c are placed onto the

second edges

13b, 14b and the front left side panel 16 and the front right side panel 17 are placed onto the respective rear left side panel 4 and rear right side panel 5. After this step, the folding process may continue according to the description given previously (with reference to fig. 2f to 2 k).
