Description

PACKAGE WITH STRESS RELIEF PANELS FIELD OF INVENTION The invention relates to a container made of a composite material, comprising: a container base with two front base corners and two rear base corners, a container gable with two front gable corners and two rear gable corners, and a container base body with a front panel, a first side panel, a second side panel, and a rear panel, wherein the container base and the container gable are arranged on opposite sides of the container base body, and wherein the composite material has an outer polymer layer, an inner polymer layer, and a fibrous support layer, which is arranged between the outer polymer layer and the inner polymer layer. BACKGROUND OF THE INVENTION Containers (in their filled state: containers) can be manufactured in various ways and from a wide range of materials. One widely used manufacturing method involves producing a blank sleeve from the container material, which is then folded and further processed to create a container sleeve and finally a container. Alternatively, it is also possible to manufacture a container directly from the blank sleeve, without the intermediate sleeve stage. This manufacturing method has the advantage, among others, that the blank sleeves and container sleeves are very flat and can therefore be stacked, saving space. This allows the blank sleeves or container sleeves to be manufactured in a different location from where the folding and filling of the container take place.Composite materials are frequently used as packaging materials; for example, a composite material consisting of multiple thin layers of paper, cardboard, plastic, and / or metal, particularly aluminum. Such packaging is widely used, especially in the food industry. Various types of composite packaging are known in the prior art. While these packages were originally quite simple geometric shapes, such as parallelepipeds, increasingly complex geometric designs are being sought to offer customers visually appealing and functionally advantageous packaging. Composite packaging with more complex geometries is known, for example, from patent documents WO 02 / 04301 Al, WO 2011 / 154173 Al, and WO 2017 / 174210 Al. One disadvantage of the packaging container described in WO 02 / 04301 Al lies in the structure of the composite material. This is because WO 02 / 04301 Al does not specify that the composite material has an inner plastic layer and an outer plastic layer, and in particular, no inner polymer layer or outer polymer layer. The disadvantage of the packaging described in WO 2011 / 154173 Al is that the edges in the sleeve area are approximately 90° and are therefore relatively and significantly twisted. This can lead to damage to the laminate, particularly cracks in the paper or cardboard layer of the laminate. In the composite packaging known from WO 2017 / 174210 Al, one disadvantage lies in the fact that the front side of the packaging merges seamlessly with the side surfaces without fold lines or crease edges, so that the front and side surfaces form a single, continuous bulge. This seamless transition between the front and side surfaces reduces stress on the laminate, but makes it difficult to achieve a defined packaging shape and can also lead to reduced rigidity of the packaging sleeve. In this context, the underlying objective of the invention is to design and develop the container described at the beginning and explained in more detail in such a way that the manufacture of containers, in particular liquid-tight containers, with even more complex geometries, is possible without affecting the rigidity of the container. BRIEF DESCRIPTION OF THE INVENTION This objective is achieved by a container according to the preamble of claim 1 in which the container base body has at least one strain relief panel, which is arranged between the front panel and one of the two side panels. The container according to the invention is manufactured, partially or entirely, from a composite material. The flat composite material has a plurality of overlapping and interconnected layers and thus forms a flat composite. The flat composite material comprises an outer polymer layer, an inner polymer layer, and a fibrous support layer, which is arranged between the outer polymer layer and the inner polymer layer. The inner polymer layer and the outer polymer layer give the composite liquid-tight properties, as they are made of plastic. The fibrous support layer (preferably paper or cardboard), on the other hand, serves primarily to give the composite material improved mechanical properties, in particular enhanced rigidity.Optionally, a barrier layer may also be provided, which is also arranged between the outer polymer layer and the inner polymer layer (preferably between the fibrous support layer and the inner polymer layer). The barrier layer may be made, for example, of aluminum and is intended to prevent the passage of light and / or oxygen. The container may also have a plurality of fold edges, which are created during container manufacturing by folding the composite material flat along the fold lines. The container initially comprises a container base with two front base corners and two rear base corners. Adjacent base corners are connected to each other by lower container edges. The container also comprises a container gable with two front corners and two rear corners. Adjacent gable corners are connected to each other by upper container edges.The container further comprises a container base body with a front panel, a first side panel, a second side panel, and a rear panel. The front panel is preferably arranged opposite the rear panel, and the first side panel is preferably arranged opposite the second side panel. The container base and the container gable are arranged on opposite sides of the container base body; in the case of a container placed on the container base, the container base is arranged below the container base body, and the container gable is arranged above the container base body. According to the invention, the container base body has at least one strain relief panel arranged between the front panel and one of the two side panels. The strain relief panel is used to create the smoothest possible transition between the front and side panels. Preferably, the strain relief panel extends the entire height of the container base body, i.e., from the container base to the gable end, and thus separates the front panel from the two side panels. The technical effect of the strain relief panel is that the composite material needs to be folded or twisted less than at a 90° edge of a rectangular container, since the transition from the front panel to the two side panels is carried out via two less twisted (blunter) edges.This leads to less stress on the composite material and, in particular, a reduced risk of cracked or broken fibers in the fibrous backing layer (paper or cardboard layer) of the composite. Preferably, the packaging has two strain relief panels, positioned between the front panel and each of the two side panels. These strain relief panels also ensure that, unlike rectangular packaging, a gap or space is created between adjacent packages in the region of the strain relief panels, allowing air to circulate. This has the advantage of reducing the risk of mold growth due to moisture.Another advantage of strain relief panels can be appreciated in that the panels or surfaces adjacent to the strain relief panels can be designed narrower and therefore more stable, thus achieving greater grip rigidity during the pouring of the filled container. According to one container configuration, the strain relief panel and the front panel are intended to be attached to the same edge of the container, specifically a base edge. In particular, the strain relief panel and the front panel may be attached together to the lower front edge of the container. According to a further container configuration, the strain relief panel and one of the two side panels are intended to be attached to the same edge of the container, specifically a gable edge. In particular, the strain relief panel and one of the two side panels may be attached together to an upper side edge of the container. Preferably, this configuration results in the strain relief panel and the adjacent front panel and / or side panel (except in the base edge or gable edge region where the panels converge) running at an angle to each other.In other words, the lower portion of the stress relief panel will be assigned to the front panel of the container, while the upper portion will be assigned to the side panel. Therefore, the stress relief panel completely wraps around an imaginary vertical edge of the container. This design of the stress relief panels has the advantage that the technical effects described above (reduced stress in the composite material, improved air circulation) occur not only on one side of the container, but on both sides. According to a further design of the container, it is proposed that a first sleeve fold line, preferably curved at least in sections, be provided between at least one strain relief panel and the adjacent front panel. Providing a fold line between the strain relief panel and the front panel creates a fold edge with a defined path, simplifying container manufacturing. The fold edge also improves the structural properties of the container, particularly its rigidity, compared to a curved shape without edges. The curved path of the sleeve fold line also facilitates the creation of convex or concave surfaces or panels, creating air gaps between adjacent containers that improve air circulation.It may be provided that a first sleeve fold line, preferably curved at least in sections, is provided between both strain relief panels and the adjacent front panel. Alternatively, the first sleeve fold line may be provided to run continuously in a curve. With regard to this design, it is further proposed that the first sleeve fold line terminate with only one of its ends at one of the two front gable corners or one of the two front base corners, and with its other end not terminating at a gable corner or a base corner. By having the first sleeve fold line terminate at one of its ends at or adjacent to one of the two front gable corners or one of the two front base corners, greater rigidity is achieved at these corners of the container. On the other hand, the end of the first sleeve fold line that does not terminate at a corner of the container and is not adjacent to it allows for the smoothest and flattest possible transition between the two surfaces or panels separated by the first sleeve fold line.For example, it may be planned that the other end of the first sleeve fold line terminates or joins an edge of the package, so that the two surfaces or panels separated by the first sleeve fold line and approaching the edge of the package may in any case be in sections approximately in a plane. pfrncnn / zznz / E / YiAi According to a further design of the container, a second sleeve fold line, preferably curved at least in sections, is provided between at least one strain relief panel and the adjacent side panel. As already explained in relation to the first sleeve fold line, the second sleeve fold line also achieves a fold edge with a defined path, which facilitates container manufacturing. The fold edge also improves the structural properties of the container, particularly its rigidity, compared to a curved shape without edges. The curved path of the sleeve fold line also facilitates the creation of convex or concave surfaces or panels, creating air gaps between adjacent containers that improve air circulation.A second sleeve fold line, preferably curved at least in sections, may be provided between both strain relief panels and the adjacent side panels. This second sleeve fold line may also be provided to run continuously in a curve. With regard to this design, it is further proposed that the second sleeve fold line terminate with only one of its ends at one of the two front gable corners or one of the two front base corners, and with its other end not terminating at a gable corner or a base corner. As already described for the first sleeve fold line, greater corner rigidity of the container can be achieved if one end of the second sleeve fold line terminates at or joins this corner. Furthermore, the other end of the second sleeve fold line, which does not terminate at a corner of the container and is not contiguous with it, allows for the smoothest and flattest possible transition between the two surfaces or panels separated by the second sleeve fold line.For example, it may be planned that the other end of the second sleeve fold line terminates or joins an edge of the package, so that the two surfaces or panels separated by the second sleeve fold line and approaching the edge of the package may in any case be in sections approximately in a plane. According to an additional container configuration, a third sleeve fold line is provided between at least one side panel and the adjacent back panel. This third sleeve fold line is preferably curved, at least in sections. As explained in relation to the first and second sleeve fold lines, this third sleeve fold line also creates a fold edge with a defined path, simplifying container manufacturing. The fold edge also improves the container's structural properties, particularly its rigidity, compared to a curved shape without edges. The curved path of the sleeve fold line also facilitates the creation of convex or concave surfaces or panels, creating air gaps between adjacent containers that improve air circulation.It may be provided that a third sleeve fold line is included between both side panels and the adjacent back panel, preferably curved at least in sections. Alternatively, the third sleeve fold line may be provided to run continuously in a curve. With regard to this configuration, it is also proposed that the third sleeve fold line terminate with one of its ends at one of the two rear gable corners and with its other end at one of the two rear base corners. By having the third sleeve fold line terminate with both ends at or attached to a gable or base corner, or at such a corner, greater rigidity is achieved at these corners of the container. Regarding the third sleeve fold line, it is also proposed that it have a plurality of sections, each of which joins a side panel and a back panel, with at least one section curved and at least one section straight. By providing a fold line between the adjacent side and back panels, a fold edge with a defined path is achieved, simplifying container manufacturing. The fold edge also improves the container's structural properties, particularly its rigidity, compared to a curved, edgeless shape. The curved path of the sleeve fold line also facilitates the creation of convex or concave surfaces or panels, creating air gaps between adjacent containers that enhance airflow.Providing straight sections in addition to the curved sections in the third sleeve fold line simplifies container manufacturing. A third sleeve fold line may be provided between both side panels and the adjacent back panel, consisting of several sections, each of which connects to a side panel and a back panel, with at least one section curved and at least one section straight. Furthermore, the third sleeve fold line may have at least two curves directed in different directions; for example, a first curve in the direction of the side panel and a second curve in the direction of the adjacent back panel (curved edge). This further improves airflow between adjacent containers. According to an additional container configuration, the section of the third sleeve fold line that joins the container base and the section of the third sleeve fold line that joins the container gable are intended to be straight. Using straight sections that join the container base and the container gable is particularly advantageous, as it allows for the use of simpler tooling to manufacture the container bases and gables. According to a further design of the container, at least two sections of the third sleeve fold line are intended to have opposite curvature directions. Specifically, one section may be curved toward the back panel and another toward the side panel. This allows for a container with both convex and concave surfaces or panels. Preferably, the section of the third sleeve fold line curved toward the side panel is positioned above the section of the third sleeve fold line curved toward the back panel. This results in a wide, concave back side of the container in the upper region, particularly in the upper half of the container.Since the containers typically have a narrow, convex front edge in their upper region, particularly in the upper half, several containers can be stacked one in front of or behind the other in a space-saving manner, thus maximizing space utilization. Furthermore, by using opposing curvature directions, the reduced filling volume caused by one curvature direction is compensated for by the other, so that the container height for a given volume remains unchanged. According to an additional container configuration, the container is designed to have a flap seam in the gable area, which is reversed toward the front panel. This design allows, for example, better moisture drainage from the gable in the case of a forward-sloping gable, as it eliminates any pockets at the top where moisture could accumulate. This design also allows for more space for an internally sealed dispenser. According to a further design of the container, the container gable is intended to be approximately trapezoidal. The trapezoidal shape of the container gable has the advantage that one of the two parallel sides or edges (preferably the front edge of the container gable) is shorter than the opposite side or edge (preferably the rear edge of the container gable), unlike a rhombus where opposite sides are the same length. This makes it easier to grip larger containers from the front with one hand. An additional container configuration involves using an oblique gable. Specifically, the gable can be designed to slope forward, meaning it is lower at the front of the container than at the rear. Due to the oblique gable, a dispensing element positioned at the gable can negatively impact stacking less than in containers with a flat gable. This is because the dispensing element does not necessarily form the highest point of the container in those with an oblique gable, unlike in those with a flat gable. Furthermore, improved moisture drainage from the gable can be achieved. According to an additional container configuration, the container gable is designed to have a curved front edge that connects to the front panel. Preferably, the front edge of the container gable is curved in the direction of the front panel. This allows for a larger surface area of ​​the container gable, facilitating, for example, the attachment of dispensing elements with a larger diameter. A curved front edge of the container gable also influences the shape of the container's front panel. In particular, a front edge curved in the direction of the front panel can create an outward-curving (convex) front panel. In addition to an attractive appearance, this also offers the previously described technical advantage of improved air circulation between adjacent containers, reducing the risk of mold growth. According to a further design of the container, the front panel is intended to be convex and / or the back panel at least partially concave. Specifically, the container may be convex in the upper region of the front panel, particularly the upper half, and / or concave in the upper region of the back panel, particularly the upper half. By combining a convex front and a concave back, the containers can be stacked in front of or behind each other, saving space despite their visually complex design. With regard to this configuration, it is further proposed that the front panel have its maximum convex protrusion above the midpoint of the container's base height. Because the front panel is particularly arched outwards or forwards in the upper region, it can be configured especially narrowly in the upper area without reducing the container's volume compared to a rectangular container; the forward protrusion thus compensates for the lateral taper. This lateral taper allows the container to be easily gripped from the front, for example, to remove it from a sales shelf with one hand. According to a further design of the container, the two front gable corners are provided to have two large gable corner angles, each greater than 90°. Alternatively or additionally, the two rear gable corners may be provided to have two small gable corner angles, each less than 90°. Angles that are not equal to 90° result in a container gable whose shape deviates from a rectangular or square form. A square container gable with two small (< 90°) and two large (> 90°) gable corner angles can be achieved, for example, by means of a trapezoid, a parallelogram, or a rhombus. In this way, it is possible to achieve a container gable with edges of different lengths, so that, for example, a short front edge can be achieved by which the container can be gripped particularly easily from the front. Finally, according to another container configuration, the four corner angles of the gable are intended to have an angle sum greater than 360°. An angle sum deviating from 360° can be achieved, for example, by one or more sides or edges of the quadrangular container gable not running straight, but curved (as in the case of an arched quadrilateral or arched polygon). An angle sum greater than 360° can be achieved by curving at least one side or edge of the quadrangular container gable outwards. The base corner angles, on the other hand, are preferably 90°, resulting in a rectangular, particularly square, container base. This container gable design pfrncnn / zznz / E / YiAi has several advantages.In addition to a more visually appealing shape, the technical effect is achieved by making the containers easier to grip with one hand. This is because one edge of the container gable (preferably the front edge) is shorter than the other edges (particularly the back edge), resulting in a narrower front. This design also reduces the contact surface between containers placed side-by-side (for example, during transport or on the sales shelf) compared to rectangular containers, where the side panels almost touch. This creates a gap or space between adjacent containers, allowing air to circulate. This reduces the risk of mold growth due to humidity. Furthermore, with the sum of the angles exceeding 360°, more space is available for a dispensing element.Preferably, the square container gable has a sum of angles of at least 370°, particularly at least 380°, and preferably at least 390°. It has been shown that a sum of angles in the range of 390° to 410° is advantageous. BRIEF DESCRIPTION OF THE FIGURES The invention will be explained in greater detail below with reference to a drawing that merely represents a preferred exemplary embodiment, wherein: Figure 1A shows a container according to the invention in perspective view. Figure IB shows the container in Figure 1A in a front view. Figure 1C shows the container in Figure 1A from a rear view. Figure ID shows the container in Figure 1A in a side view. Figure 2A shows a first region of the container in Figure 1A in enlarged view. Figure 2B shows a second region of the container from Figure 1A in enlarged view. DETAILED DESCRIPTION OF THE INVENTION Figure 1A shows a container 1 according to the invention in perspective view. Figure 1B shows the container 1 of Figure 1A in a front view, Figure 1C in a rear view, and Figure 1D in a side view. The container 1 has a quadrangular container base B, which has two front base corners BV1, BV2 and two rear base corners BH1, BH2. The container 1 also has a quadrangular container gable G, which has two front gable corners GV1, GV2 and two rear gable corners GH1, GH2. Furthermore, container 1 has a container base body K comprising a front panel F, a first side panel Si, a second side panel S2, and a rear panel R. The container base body K is arranged between the container base B and the container gable G such that the container base B and the container gable G are arranged on opposite sides of the container base body K and form a container sleeve surface 1.Container 1 is made partially or entirely of a composite material having an outer polymer layer, an inner polymer layer, and a fibrous backing layer between the outer and inner polymer layers. The fibrous backing layer can be, for example, a layer of paper or cardboard. In the container gable region G, container 1 has a flap seam 2, which is turned in the direction of the front panel F. In the container gable region G, container 1 also has two tabs 3, one tab 3 being applied to the first side panel Si and the second tab 3 being applied to the second side panel S2. In the rear panel region R, container 1 has a longitudinal seam 4. The container gable G is approximately trapezoidal and is designed as a sloping gable (like a pitched roof).The container gable G has a front edge V, which is curved in the direction of the front panel F and joins to the front panel F. Further details on the shape of the container gable will be provided in relation to Figure 2A. The container base K of container 1, shown in Figure 1A to Figure 1ID, has two strain relief panels El, E2. The first strain relief panel El is positioned between the front panel F and the first side panel Si, and the second strain relief panel E2 is positioned between the front panel F and the second side panel S2. The strain relief panels El, E2 thus separate the front panel F from the two side panels Si, S2 and form a transition between the front panel F and the two side panels Si, S2. The first strain relief panel El and the second strain relief panel E2 are located in the region where the container base B meets the front panel F in sections within a plane.However, the first strain relief panel El is located in the region where the container gable G joins the first side panel Si in sections in one plane; similarly, the second strain relief panel E2 is located in the region where the container gable G joins the second side panel S2 in sections in one plane. Therefore, the two strain relief panels El, E2 are assigned in their lower regions to a different side of container 1 than in their upper regions; the two strain relief panels El, E2 thus “wrap” around an imaginary container edge from the front panel F in the direction of one of the two side panels Si, S2. In the package 1 shown in Figures 1A to ID, a first sleeve fold line MI, which is continuously curved, is provided between the front panel F and the first strain relief panel El. A second sleeve fold line MI, which is also continuously curved, is provided between the front panel F and the second strain relief panel E2. The first two sleeve fold lines MI are joined, at their upper ends, to the two front gable corners GV1, GV2. However, at their two lower ends, the first two sleeve fold lines MI are not joined to the two front base corners BV1, BV2, but rather to points on the lower front package edge that lie between them. In package 1, a second sleeve fold line M2, which is also continuously curved, is provided between the first strain relief panel El and the adjacent first side panel Si.A second sleeve fold line, M2, which is continuously curved, is also provided between the second strain relief panel E2 and the adjacent second side panel S2. The two second sleeve fold lines M2 are attached, at their lower ends, to the two front gable corners BV1, BV2. However, at their upper ends, the two second sleeve fold lines MI are not attached to the two front gable corners GV1, GV2, but rather to points on the upper side container edges located between the front gable corners GV1, GV2 and the rear gable corners GH1, GH2. In package 1 shown in Figure 1A to Figure ID, a third sleeve fold line M3 is provided between the first side panel Si and the adjacent back panel R. A third sleeve fold line M3 is also provided between the second side panel Si and the adjacent back panel R.The third sleeve fold line M3 is attached, at one end, to one of the two rear gable corners GH1, GH2 and at its other end to one of the two rear base corners BH1, BH2. Further details on the exact path of the third sleeve fold line M3 will be provided in relation to Figure 2B. pfrncnn / zznz / E / YiAi From the side view (Figure ID), it is particularly clear that the front panel F is convex, that is, it curves outwards. The front panel F has its maximum convex protrusion above the midpoint of the container base body K. It can also be discerned in Figure ID that the rear panel R is concave, that is, it curves inwards. Figure 2A shows a first region of container 1 from Figure 1A in an enlarged view. The regions of container 1 already described in relation to Figure 1A through Figure 1D are provided with corresponding reference numbers in Figure 2A. The first region of the container depicted in Figure 2A relates to the region of container gable G, in particular to the front gable angle region GV2 (and the gable corner angle acv2 therein) and to the rear gable angle region GH1 (and the gable corner angle qghi therein). The same applies to the other half of container gable G (not depicted in Figure 2A) due to symmetry.The four corners of container gable G are not at right angles: The two front gable corners GV1, GV2 have front gable corner angles αονι, acv2, which are slightly greater than 90° (αονι, acv2 > 90°) and the two rear gable corners GH1, GH2 have rear gable corner angles oghi, ctGH2, which are slightly less than 90° (ughi, ugh2 < 90°). For the rear gable corner angles (xghi, aom, the deviation from a right angle is due to the fact that the upper side container edges that join the rear gable corner angles «ghi, ugh2 do not run at right angles to the upper rear container edge, but are inclined at an angle βι to a vertical SR1 (cighi = ασH2 = 90oβι).For the front gable corner angles ugvi, ugv2, the deviation from a right angle has two reasons: firstly, the upper side container edges that join the front gable corner angles ασνι, ugv2 do not run at right angles to the rear container edge, but are inclined at an angle β2 with respect to a vertical SR2. Secondly, the front edge V which also joins the front gable corner angles ogvi, acv2 does not run straight, but curved in the direction of the front panel F, where the front edge V (or a tangent touching the front edge V in the region of the front gable corners GV1, GV2 or the gable corner angle αονι, αον2 there) is inclined at an angle γ with respect to a horizontal WR (running parallel to the upper rear container edge) (acvi = aov2 = 90° + β2+ γ).The angle βι corresponds to the angle β2; both angles are preferably in the range between 2 and 6°. Therefore, the two angles of the rear gable corners acm, aGH2 can be, for example, in the range of approximately 86°. The angle γ is preferably in the range between 15° and 25°. The two angles of the front gable corners acvi, acv2 can therefore be in the range of approximately 113°, for example. From the described design, in particular the curved front rim V, it follows that the sum of the angles of the square container gable G is greater than 360° (aovi + aov2 + βhi + βgh2 > 360°). Figure 2B shows a second region of package 1 from Figure 1A in an enlarged view. The regions of package 1 already described in relation to Figure 1A through Figure 2A are provided with corresponding reference numbers in Figure 2B. The second region of package 1 depicted in Figure 2B relates to the region of the third sleeve fold line M3, which separates the back panel R from the two side panels Si, S2 (only one of the two third sleeve fold lines M3 is shown in Figure 2B; the same applies to the other third sleeve fold line M3 due to symmetry). The third sleeve fold line M3, located between the back panel R and the adjacent side panels Si, S2, has four sections I-IV: the first section I is attached to the package base B and runs straight. The second section II is attached to the first section I and runs curved (in the direction of the back panel R).As a result of the curvature, there is a maximum distance dn between the third sleeve fold line M3 and a vertical SR3, which can range from 0.5 mm to 2.5 mm. The third section III is attached to the second section II and runs in a curve (in the direction of the first side panel Si). As a result of the curvature, there is a maximum distance dm between the third sleeve fold line M3 and the vertical SR3, which can range from 0.5 mm to 2.5 mm. The second section II and the third section III therefore have opposite curvatures or directions of curvature. The fourth section IV is attached to the third section III and to the container gable G and runs straight. Therefore, the third sleeve fold line M3 runs straight in some sections (in section I, which is attached to the container base B, and in section IV, which is attached to the container gable G) and is curved in others (in the two central sections II and III). pfrncnn / zznz / E / YiAi 1: 2: 3: REFERENCE NUMBER LIST Packaging Flap seam Lug 4: Longitudinal seam aoni, ogv2: Front gable corner angles aski, aGH2: Rear gable corner angles βi> β2: γ: Slant angle Slant angle B: Packaging base BV1, BV2: Front base corner BH1, BH2: Rear base corner dn, din: Distance E1, E2: Stress relief panel F: Front panel G: Packaging gable GV1, GV2: Front gable corner GH1, GH2: Rear gable corner K: Packaging base body MI: First sleeve fold line M2: Second sleeve fold line M3: Third sleeve fold line D: Back panel Yes, Yes: Side panel SR1, SR2, SR3: Verticals V: Front edge (of the container gable G) WR: Horizontals I, II, III, IV: Sections (of the third sleeve fold line M3) pfrncnn / zznz / E / YiAi
