Description

Containers for liquids or products that can be pour.

Technical sector

The present invention refers to a container for liquid products or that can be poured as they are juices, milk, wine, sauces, broths, flakes, cereals, etc.

State of the art

This type of packaging is made from a material with a multilayer structure comprising for example a layer of fiber material, for example, cardboard, coated by both sides with two layers of plastic material, for example, polyethylene, and in the case of long-term aseptic packaging as UHT milk, it also comprises a thin aluminum foil which acts as a barrier against oxygen and which in turn is coated on the inside of the container with another layer of plastic material that prevents the contact of aluminum with the product.

One type of these containers are the containers in form of parallelepiped, "brik", which are formed from a continuous tube obtained by the longitudinal sealing of the material of container. The material is sterilized in the machine itself hydrogen peroxide filling that is removed subsequently with water vapor from the surfaces of the container. Subsequently, the tube is filled with the product sterilized and sealed and cut transversely at intervals equal and determined to form the individual units that they have a typical pillow shape and that thanks to the folding later on the same machine they acquire their definitive form of parallelepiped or polyhedron.

Currently it tends to manufacture containers that optimize the relationship between product quantity packaging and the surface of the container which reduces the cost of the container Among this type of packaging we have the section hexagonal and octagonal cross-section instead of the traditional Rectangular or square section such as the following Patents: EP0999982, EP0650895 or EP1275588.

There are other filling technologies and conformation of this type of packaging but this type of filling and Packaging shaping is easier and cheaper.

To allow the final conformation of the container, from the pillow-shaped structure, the material of the container must have some folding lines, which are actually lines of weakness, which correspond to the edges and lines of folds of the container once formed. This set of lines and their particular arrangement is what is known as a folding pattern "create pattern" and the packaging material itself with this folding pattern as "blank" or "web packaging material".

A first aspect of the present invention is provide a set of packages adapted to said technology of filling without substantial modification of the machinery, which also optimize the relationship between the quantity of packaged product and the container surface being its octagonal cross section and decrease the surface of the flaps that form after the folding and also allow the installation of a device product spill on one of its bases.

A second aspect of the invention is to provide new forms of upper bases or lower bases that can be combine perfectly with the structures of other packages already Existing or future.

A third aspect of the present invention is provide packaging materials with a folding pattern Suitable for obtaining each container.

A fourth aspect of the present invention is provide some methods for obtaining said containers.

They are presented below, by way of example, four types of preferred but not limiting packaging of the present invention, taking into account that when describing forms or lengths of its elements or panels that the container or the packaging material values are given that allow a margin that It depends on the thickness of the packaging material, the goodness and quality of the folding done by the machines and the desired shape of the Packaging elements: bases, flaps or main body.

Figures 1, 2 and 3 show different views of a first container 1 according to the present invention. This first container 1 is manufactured from a packaging material with folding pattern 2, which we will refer to hereinafter as "material of container 2 ". Said container is formed by a main body 3 of eight walls 4. This main body 3 has a section regular octagon shaped cross whose sides and angles are equal (the interior angle formed by two consecutive walls is 135º) as can be seen in figure 3. In others alternatives the section of said main body may present Octagon shape not regular.

This first container 1 also has a base upper 5 and another lower 6 that are identical so that only describe the upper one as it appears in figures 1,2 and 3. It is base 5, which is not flat, has a flat central zone 7 and four lateral areas that protrude and end at the tip or peak 8, 9, 10, eleven.

The flat central area 7 can have a shape square as shown in figure 3 and in other alternatives presents derived forms: a rhombus, a polygon with more than four sides and some or all sides of the perimeter instead of being straight They can be curved.

Limiting with the base and folded over it and out of volume available for the product is a pair of opposite flaps 12, 13. Flap 12 is superimposed and covering part of the lateral areas that protrude 8, 9 and part of the central flat area 7 and in the same way the flap 13 covers part of the lateral areas that protrude 10, 11 and part of the flat central zone 7. Each of these flaps includes the portion of the ends of a narrow sealing zone 14.

This sealing zone 14, whose central part borders the base 5, crosses it from one vertex to the other opposite vertex and its portions of the ends are continued by the flaps 12, 13 as already said. Once the flaps 12, 13 have been folded on the base, the sealing zone 14 is almost completely hidden by said
flaps

The container also has a second zone cross seal 15 and a second pair of flaps (not seen in the figures) that limit with the base 6 and that are identical and located in the same way as those that limit with base 5.

The first container 1 is manufactured by a process that manages to form a continuous tube from the material of container 2 when joining and sealing the longitudinal sealing area 16 with the opposite edge 17 of the packaging material 2 (figure 6). This zone Longitudinal sealing can be seen partly in the package finished of figure 1 according to reference 18. This tube is filled with the product and subsequently it is also sealed and transversely cut at regular intervals forming a product intermediate in the manufacture of the pillow-shaped container 19 called "pillow pack" and that shows figure 4 and where you can see a central body 20 of eight walls and two zones in wedge shape 21, 22 and the two transverse sealing zones 14, 15 of the container

The central body 20 corresponds to the main body 3 of the finished container and the wedge-shaped area 21 will result after folding the base 5 and the pair of flaps 12, 13 that after folding are superimposed on the base 5 and the wedge-shaped area 22 will give rise to the base 6 and its corresponding pair of flaps (not seen in the
figures).

Figure 6 shows in addition to the special arrangement, location and orientation of the folding lines, the proportions and angles of some lines with respect to others. All derives from the geometric calculation represented in figure 5, which shows a side view of the container and a view from below of the same, and that basically consists in determining how much the lateral zones 8, 9, 10, and 11 of the base stand out with with respect to the central flat zone 7 and ultimately the magnitude of those tips or spikes of the bases of the container.

In this first container 1, the projection of the base on a plane containing the flat area of the base, or what is the same, that is perpendicular to the longitudinal axis of the body of the container, coincides with the cross section of the body of the container, and is a regular octagon whose side is represented by the letter " s ". It must be fulfilled that the sum of the distance from point E to point B plus the distance from point B to point D plus the distance from point D to point A must be equal to the distance from point 0 to point C for the container It can be constructed from a flat and rectangular shaped container material. This is only true if the magnitude of those points or peaks that are represented by the letter " p " is approximately equal to the difference between the values of the distance from the point O that is the center of the octagon, to point C , vertex of the octagon, and that is represented by the letter " d ", minus the length of the s side of the octagon. Thus, since d is equal to s divided by 2cos67.5º , or what is the same, d is equal to 1.3065 s , it is verified that the value p , which is equal to d minus s , is of this form 0.3065 s . Therefore, to obtain the value of p we will multiply the value of s , which is normally the main starting data for the design of the package, by a factor f of 0.30.

Regarding this point, we have to point out that for values of f substantially different from 0.30 we obtain bases (and by extension containers) of the same characteristics unless its projection on said plane is no longer a regular octagon and that these alternatives are also within the scope of the present invention.

Figure 6 shows a representation of the packaging material with folding pattern corresponding to the first container 1.

In the packaging material 2, the folding pattern 23 is constituted by a set of folding lines or weakness practiced in said packaging material 2 and especially arranged that correspond to the edges and fold lines of the container once formed.

In this packaging material 2, the pattern of folding 23 by means of its folding lines forms a network that divide the packaging material into a set of panels that correspond to the finished container with faces, flaps or areas of sealed. This set of panels is formed by a first zone cross section of sealing panels 24 and a second cross section of panels 25 that limits with the previous one that corresponds to one of the bases and pair of flaps of the container and also a third zone of panels 26, which are elongated and in the form of an isosceles trapezoid, which it borders the second transverse zone 25 and that corresponds to The body of the container. This set of panels also has a first symmetric zone 27 to the second transverse zone 25, which it borders the third panel area as well, and a second zone symmetrical 28 to the first transverse zone of sealing panels 24, which limits with the previous one, the axis of symmetry being an axis transverse that passes through the center of the third panel area 26. Both symmetric zones 27,28 have the same arrangement as the  originals so they will not be described in detail. By last, it also comprises a longitudinal zone of sealing panels 16 and described above.

The second cross-sectional area of panels 25 is constituted by a set of panels obtained by a composition of panels derived from a base module 29 which is formed by:

- A first panel 30 shaped like a trapeze rectangle that has a first side 31 with perpendicular direction to the first zone of sealing panels, a second side 32 perpendicular to the first one that borders the first transverse zone of sealing panels 24, a third side 33 perpendicular to the anterior and perpendicular to the first panel area sealing, a fourth side 34 that forms an obtuse angle with the side  anterior and acute one with the first side 31.

- A second panel 35 with a triangle shape scalene whose major side coincides with the fourth side 34 of the first panel 30, a second side 36 with direction perpendicular to the first zone of sealing panels and a third side 37 that forms a obtuse angle with the previous one and that limits with the third zone of panels 26.

- A third panel 38 with a trapezoid shape that it has a first side that matches the third side 33 of the first panel 30, a second side 39 that borders the first zone transverse sealing panels 24, a third side 40 forming a acute angle with the previous one and a fourth side 41 that forms a angle with the previous one and obtuse with the first side

- A fourth panel 42 with a triangle shape that it has a first side that matches the second side 36 of the second panel 35, a second side that coincides with the fourth side 41 of the third panel 38, a third side 43 that forms a right angle with the previous.

- A fifth panel 44 with a triangle shape that it has a first side that matches the third side 43 of the fourth panel 42, a second side 45 that forms a right angle with the anterior, and a third side 46 that borders the third zone of panels 26.

- A sixth panel 47 with a triangle shape that it has a first side that matches the third side 40 of the third panel 38, a second side 48 with direction perpendicular to the first zone of sealing panels and a third side that matches the second side 45 of the fifth panel 44 and forms a right angle with The first side.

The composition of panels that form the second cross-sectional area of panels 25 is first obtained by adding to said base module 29 a symmetric module thereof 49 with respect to an axis of symmetry 50 with direction perpendicular to the first zone of sealing panels and coinciding with the second side 48 of the sixth panel 47 and in turn add to this primary composition 51 other symmetric composition 52 to said primary composition 51 with respect of an axis of symmetry 53 with direction perpendicular to the first sealing panel area that matches the first side 31 of the First panel 30 of the base module 29 of the primary composition 51. Finally, between the pairs of panels that limit through a side that matches an axis of symmetry 50, 53 or whatever same, between the pairs of panels that limit through side 31 and 48 described, there is no folding line and they form a single panel in the final composition of the second cross-sectional area of panels 25.

Taking into account the previous description of the second cross-sectional area of panels 25 and geometric calculation previous, what interests is to obtain the proportions that must have the elements of the panels of the second transverse zone of panels 25 to be able to build base 5 and flaps 12, 13 in that the aforementioned, projection of the base, is a regular octagon. These proportions vary although slightly from the theoretical ones (given in parentheses) for a real package, whose  material has a thickness and offers resistance to folding, and always these slight variations will depend on the thickness of the material of container and the quality of the folding made by the machines.

In this way, the elements of the base module 29 they keep the following proportions:

The length of the first side 31 of the first panel divided by a factor of 1.30 is equal to the length of the second side 32 of the first panel divided by a factor of 1.03 (1.00) and a in turn it is equal to the length of the third side 33 of the first panel divided by a factor of 0.30 and in turn is equal to the length on the second side 36 of the second panel divided by a factor of 0.70 and in turn is equal to the length of the second side 39 of the third panel divided by a factor of 0.97 (1.00) and in turn is equal to the length of the second side 48 of the sixth split panel by a factor of 1.30.

On the other hand, the folding line 54 which separates said second cross-sectional area of panels 25 from said third zone of panels 26 is a broken line and the distance that separate imaginary straight lines that pass through alternate vertices of said broken line is equal to the length of the second side 32 of the first panel 30 of said base module multiplied by a factor of 0.29 (0.30).

As can be seen, all the above factors derive from the aforementioned factor f = 0.30 of the geometric calculation, (0.70 = 1- 0.30, 1.30 = 1 + 0.30), and the result of all and each of these divisions is equal to the value of the s side of the regular octagon already mentioned, and which coincides with the width of the panels of the third panel area 26.

To obtain packaging materials with a pattern of alternative folding corresponding to containers whose projection of the base no longer matches a regular octagon there is no more than vary significantly the previous factors remaining also within the scope of the present invention.

Figures 7, 8 and 9 show different views of a second container 55 according to the present invention. This second container 55 is made from a container material with folding pattern 56, which we will call "material" of container 56 ". Said container is formed by a main body 57 of eight walls, one upper base 58 and one lower 59 which are similar to those of the first container 1 and which also admits as alternatives to those of the first container 1 so They will not be described again.

Limiting with the lower base 59 is a pair of flaps and a transverse sealing zone equal in form and arrangement to those of the first container 1 so they will not be described again. Limiting with the upper base 58 and folded, in part on the base 58 and partly on the body walls main 57 and out of volume available for the product, it find a pair of opposite flaps that are only seen in figures one of them according to reference 60. This flap 60 it is superimposed and covering part of base 58 and part of two main body walls 57 and extends between the peaks of the elevated areas. The other flap has the same shape and provision. Each of these flaps includes the portion of the ends of a narrow sealing zone 61.

This sealing zone 61, whose central part it borders base 58, crosses it from a vertex to another opposite vertex and its end portions are continued by the flaps as already said.

In the same way as the first container 1, the second container 55 is manufactured by a process that achieves form a continuous tube from the packaging material 56 when joining and seal the longitudinal sealing zone 62 with the opposite edge 63 of packaging material 56 (figure 10). This longitudinal zone of sealed can be seen partly in the finished container of the Figure 9 according to reference 64 and it is also possible to obtain the intermediate product in the manufacture of the container, a "pillow pack ". In this case after folding the flaps that limit with the upper base 58 is folded, partly on the base itself upper 58 and partly on the walls of the main body 57.

The geometric calculation represented in al Figure 5 is applicable in this second container 55 as well and is they will take into account the same considerations made in the description of the first container 1 above for the magnitude of the tips or spikes of the bases.

Figure 10 shows a representation of the packaging material with folding pattern corresponding to the second container 55.

In this packaging material 56, the pattern of folding 65 by means of its folding lines forms a network that divide the packaging material into a set of panels that correspond to the finished container with faces, flaps or areas of sealed. This set of panels is formed by a first zone transverse sealing panels 66, a second transverse zone of panels 67, a third zone of panels 68, a fourth zone cross section of panels 69, and a fifth cross sectional area of panels sealing 70 and also has a longitudinal area of panels sealed 62 described above.

Except for the second zone of panels 67 all others are equal in form and disposition to the corresponding panel areas of the panel assembly of the packaging material 2 of the first container 1 and will not be described again.

Said second cross-sectional area of panels 67 It consists of a set of panels obtained by a panel composition derived from a base module 71 which is formed by:

- A first panel 72 with a triangle shape rectangle that has a first side 73 with direction perpendicular to the first zone of sealing panels, a second side 74 perpendicular to the first one that borders the first transverse zone of sealing panels 66 and a third side 75 that closes said triangle.

- A second triangle-shaped panel 76 that it has a first side that matches the third side 75 of the first panel 72, a second side 77 that forms an acute angle with the anterior and a third side 78 that forms an obtuse angle with the previous and that limits with the third zone of panels 68.

- A third panel 79 with a triangle shape scalene that has a first side that matches the second side 77 of the second panel 76, a second side 80 that borders the first cross-sectional area of sealing panels 66, a third side 81 that forms acute angles with the other two.

- A fourth panel 82 with a triangle shape scalene that has a first side that matches the third side 81 of the third panel 79, a second side 83 with direction perpendicular to the first zone of sealing panels, a third side 84 that forms an obtuse angle with the previous one.

- A fifth panel 85 with a triangle shape that it has a first side that matches the third side 84 of the fourth panel 82, a second side 86 with direction perpendicular to the first zone of sealing panels, a third side 87 forming a right angle with the previous one.

- A sixth panel 88 with a triangle shape that it has a first side that matches the third side 87 of the fifth panel 85, a second side 89 with direction perpendicular to the first zone of sealing panels and a third side 90 that forms acute angles with the other sides and that borders the third zone of panels 68.

The composition of panels that form the second cross-sectional area of panels 67 is first obtained by adding to said base module 71 a symmetric module thereof 91 with respect to an axis of symmetry 92 with direction perpendicular to the first zone of sealing panels coinciding with the second side of the room, fifth and sixth panels 82, 85, 88 and in turn add to this primary composition 93 another symmetric composition 94 to said primary composition 93 with respect to an axis 95 with direction perpendicular to the first zone of sealing panels that matches with the first side 73 of the first panel 72 of the base module 71 of the primary composition 93. Finally, between the pair of panels that limit through one side that matches the axis of symmetry 95 or which is the same, between the pair of panels that limit through from side 73 of the first panel 72, there is no folding line and they form a single panel in the final composition of the second zone cross section of panels 67.

Taking into account the previous description of the second cross-sectional area of panels 67 and geometric calculation previous, what interests is to obtain the proportions that must have the elements of the panels of the second transverse zone of panels 67 to be able to build the upper base 58 and a pair of flaps in which the aforementioned, projection of the base, Be a regular octagon. These proportions vary, as has already been commented, slightly from the theoretical ones (which occur between parenthesis).

In this way, the elements of the base module 71 they keep the following proportions:

Length of the first side 73 of the first panel divided by a factor of 1.30 is equal to the length of the second side 74 of the first panel divided by a factor of 1.33 (1.30) and a in turn it is equal to the length of the second side 80 of the third panel divided by a factor of 0.67 (0.70) and in turn is equal to the length of the second side 83 of the fourth panel divided by a factor of 0.67 (0.70) and in turn is equal to the length of the second side 86 of the fifth panel divided by a factor of 0.33 (0.30) and a in turn it is equal to the length of the second side 89 of the sixth panel divided by 0.33 (0.30) and in turn is equal to the distance from the common vertex of the second 76, third 79, fourth 82 panels, fifth 85 and sixth 88 of the base module to the folding line of said first cross-sectional area of sealing panels 66 divided by a 0.97 factor (1).

On the other hand, the folding line 96 which separates said second cross-sectional area of panels 67 from said third zone of panels 68 is a broken line and the distance that separate imaginary straight lines that pass through alternate vertices of said broken line is equal to the length of the second side 74 of the first panel of said base module multiplied by a factor of 0.26 (0.23) (where 0.23 = 0.30 divided by 1.30).

As can be seen, all the above factors also derive from the aforementioned factor f = 0.30 of the geometric calculation, (0.70 = 1- 0.30, 1.30 = 1 + 0.30), and the result of each and every one of those divisions is equal to the value of the s- side of the regular octagon already mentioned, and which coincides with the width of the panels of the third zone of panels 68.

To obtain packaging materials with a pattern of alternative folding (and by extension containers) there is only vary significantly the above factors also remaining within the scope of the present invention.

Figures 11, 12 and 13 show different views of a third container 97 according to the present invention. This third container 97 is manufactured from a material of container with folding pattern 98, which we will call from now on "packaging material 98". Said container comprises a body main 99 with eight walls, a bottom base 100, some flaps and a sealing zone that limit with this bottom base 100 which are all similar to those of the first container 1 and which also admits as alternatives to those of the first container 1 so They will not be described again.

This third container 97 also comprises a roof-shaped upper part 101 which includes a front inclined lid 102 and a rear inclined lid 103, adjacent and joined both by the central portion of a narrow cross-sectional sealing area 104 which is located in the easel of said roof. Said inclined covers 102, 103 are not flat. The front inclined cover 102 has a recessed central zone 105 with respect to two raised lateral areas 106, 107 protruding into points or spikes and the rear inclined cover similarly has a recessed central zone 108 with respect to two raised lateral areas 109, 110 that protrude Similarly. These raised areas border the walls of said main body 99. Said inclined covers 102, 103 are formed as shown in Figure 11 by three non-coplanar triangular flat surfaces, but as alternatives they can also be constituted by at least one curved surface or by a combination of flat surfaces and
curves

The package also comprises a pair of flaps opposite 111, 112 that limit the top of the container 101 which include the portions of the ends of said zone transversal seal 104 and are folded and superimposed on the walls of said main body 99 outside the volume Available for the liquid or product. These flaps border with a part of the perimeter of the inclined covers 102, 103. The flap 111 comprises two subsolaps so that one of them 113 is superimposes a part of the other subsolapa 114 and this subsolapa 114 it overlaps in turn on a part of two consecutive walls and extends from the peak of elevated zone 107 to the peak of the elevated zone 109. The flap 112 has an arrangement and analogous structure

In the same way as the first container 1, the third container 97 is manufactured by a process that manages to form a continuous tube from the packaging material 98 when joining and seal the longitudinal sealing area 115 with the opposite edge 116 of packaging material 98 (Figure 15). This longitudinal zone of sealed can be seen partly in the finished container of the Figure 11 according to reference 117 and the same is reached obtain the intermediate product in the manufacture of the container, a "pillow pack". One of its wedge-shaped ends is formed by the inclined front and rear covers 102, 103 and by the flaps 111, 112 half folded that are located at the peaks of the pillow-shaped body

In figure 15 it is observed in addition to the special arrangement, location and orientation of the folding lines, the proportions and angles of some lines with respect to others. All derives from the geometric calculation represented in figure 14 that shows a side view of the container and a top view of the same, and that basically consists in determining the shape of the upper part of the container that has a roof shape.

In this third container 97, and according to Figure 14, the projection of the upper part 101 on a plane perpendicular to the longitudinal axis of the container body coincides with the cross section of the container, and is an octagon whose side is represented by the letter " s ". It must be fulfilled that the sum of the distance from point E to point B plus the distance from point B to point D plus the distance from point D to point A must be equal to the distance from point O to point C for the container It can be constructed from a flat and rectangular shaped container material. This is only true if the difference in height between point D and E is " p " and the difference in height between point C and E is " 3p ", taking into account that " p " is approximately equal to the difference between the values of the distance from point O that is the center of the octagon, to point C, vertex of the octagon, and that is represented by the letter " d ", minus the length or width " s " on the side of the octagon as seen above.

Also here, d is equal to s divided by 2cos67.5º , or what is the same, d is equal to 1.3065 s and therefore also p = d - s = 0.30 s . Therefore, to obtain the value of p we will multiply the value of s, which is normally the main starting data for the design of the package, by a factor f of 0.30.

Thus, the difference in height between point D located at a peak of a cover and E located on the roof stand is p = 0.30 s and the difference in height between point C which is the lowest point of the lid and the E of the easel is 3p = 3 x 0.30 s = 0.90 s .

Regarding this point, we also have to point out that for values of f substantially different from 0.30 we obtain a top 101 of the container (and by extension containers) of the same characteristics unless its projection on said plane is no longer a regular octagon and that these alternatives are also within the scope of the present invention.

Figure 15 shows a representation of the packaging material with folding pattern corresponding to the third container 97.

In this packaging material 98, the pattern of folding 118 by means of its folding lines forms a network that divide the packaging material into a set of panels that correspond to the finished container with faces, flaps or areas of sealed. This set of panels is formed by a first zone cross section of sealing panels 119, a second cross section of panels 120 corresponding to the top and pair of container flaps, a third zone of panels 121 that is corresponds to the body of the container, a fourth transverse zone of panels 122, which borders the previous one, a fifth zone transverse sealing panels 123, which borders the previous one, and a longitudinal zone of sealing panels 115 above described.

Except for the second and third zone of panels 120, 121 all others are equal in form and disposition to corresponding panel areas of the panel set of the container material 2 of the first container 1 and will not be described in new.

The third zone of panels 121 is formed by eight rhomboid-shaped panels half and trapezoid the other half.

The second cross-sectional area of panels 120 is constituted by a set of panels obtained by a panel composition derived from a base module 124 which is formed by:

- A first panel 125 with a triangle shape rectangle that has a first side 126 with perpendicular direction to the first zone of sealing panels, a second side 127 perpendicular to the first one that borders said first zone transverse sealing panels 119, a third side 128 that close that triangle.

- A second triangle-shaped panel 129 which has a first side that matches the third side 128 of the first panel, a second side 130 that forms an acute angle with the anterior, a third side 131 that forms an obtuse angle with the previous and limits with the third zone of panels 121.

- A third panel 132 with a triangle shape scalene that has a first side that matches the second side 130 of the second panel, a second side 133 that borders said first cross-sectional area of sealing panels 119, a third side 134 that forms acute angles with the other two.

- A fourth panel 135 with a triangle shape scalene that has a first side that matches the third side 134 of the third panel, a second side 136 with direction perpendicular to the first zone of sealing panels, a third side 137 that forms an obtuse angle with the previous one and borders the third panel area 121.

The composition of panels that form the second cross section of panels 120 is first obtained from adding to said base module 124 a symmetric module thereof 138 with respect to an axis of symmetry 139 with direction perpendicular to the first zone of sealing panels coinciding with the second side 136 of the fourth panel 135 and in turn add to this composition primary 140 a symmetrical composition 141 with respect to an axis 142 with perpendicular direction to the first zone of sealing panels which matches the first side 126 of the first panel 125 of the module base 124 of primary composition 140. Moreover, between the pair of panels that limit through one side that matches the axis of symmetry 142 or what is the same, between the pair of panels which limit through the side 126 of the first panel 125, there is no folding line and form a single panel in the final composition of the second cross-sectional area of panels 120.

Finally, in at least one module of the primary composition 140 and in at least one module of the composition symmetric 141 to said primary composition, the third panels and fourth of the base module are subdivided into two subpanels triangular, obtaining for example subpanels 144a, 144b, 142a, 142b, and 146a, 146b, 147a, 147b.

Taking into account the previous description of the second cross-sectional area of panels 120 and geometric calculation previous, what interests is to obtain the proportions that must have the elements the panels of the second transverse zone of panels 120 to be able to build the top 101 and flaps 111, 112 in which the aforementioned, projection of the part top of the container, be a regular octagon. These proportions vary, as already mentioned, slightly from the theoretical ones (which are given in parentheses).

In this way, the elements of the base module 124 they keep the following proportions:

Length of the second side 127 of the first panel divided by a factor of 1.27 (1.30) is equal to the length of the first side 126 of the first panel divided by a factor of 1.63 (1.60) and in turn is equal to the length of the second side 133 of the third panel divided by a factor of 0.73 (0.70) and in turn is equal to the length of the second side 136 of the fourth divided panel by a factor of 0.70 and in turn is equal to the distance from the common vertex of the second 129, third 132, fourth 135 panels from the base module to the folding line of said first zone cross section of sealing panels 119 divided by a factor of one.

On the other hand, the folding line 143 which separates said second cross-sectional area of panels 120 from said third panel area 121 is a broken line and we can draw three imaginary straight lines parallel to the previous one that pass through  certain vertices of the broken line so that they keep the proportion:

Length of the second side 127 of the first panel divided by a factor of 1.27 (1.30) is equal to the distances of the folding line of the third panel area 121 with respect to the first imaginary line divided by a factor of 0.7, with respect to the second imaginary line divided by a factor of 1 and respect to the third divided by a factor of 1.63 (1.60).

As can be seen, all the above factors also derive from the aforementioned factor f = 0.30 of the geometric calculation, (0.70 = 1- 0.30, 1.30 = 1 + 0.30, 1.60 = 1 + 0.30 + 0.30), and the result of each and every one of those divisions is equal to the value of the s-side of the regular octagon already mentioned, and which coincides with the width of the panels of the third panel area 68 .

To obtain packaging materials with a pattern of alternative folding (and by extension containers) there is only vary significantly the above factors also remaining within the scope of the present invention.

Figures 16, 17 and 18 show different views of a fourth container 148 according to the present invention. This fourth container 148 is practically similar to the third container 97 and is made from the same packaging material with a pattern of  folded 118 of figure 15 and it is also possible to obtain the intermediate product in the manufacture of the container, the "pillow pack ". The difference of this fourth container 148 with respect to third container 97 is that the pair of opposite flaps 149, 150 that limited to the top of the container 151, and that include the portions of the ends of the transverse sealing zone, are folded and hidden inside the volume available for the liquid or product which greatly improves the image of the container.

Naturally, within this set of octagonal section containers there may be a hybridization constructive that we will point out. The second 55, third containers 97, room 148 as seen use as lower base and flaps that border on it, the same base and flaps as the belonging to the first container 1 but can also use and are within the scope of the present invention, the upper base and the flaps that border on it and that are folded over the container walls corresponding to the second container 55. Also It is noteworthy in the first place that this type of lower base with the two flap arrangements (folded on the same basis or well folded on the walls of the container) can be used in combination with other existing packaging bodies and different from those seen here and secondly, that the same thing happens with the upper part of the third 97 and fourth 148 containers and their two flap arrangements (folded over container walls or well placed within the volume for the product) which also can be used combined in other packaging bodies since existing.

Finally, these packages allow incorporating lines of weakness or stippling in one of its flaps that facilitate cutting or tearing to form a pouring spout or a own pouring device fixed on one of its bases or lid top, as shown by some of the figures that by way of example they have represented it, which facilitate the opening, the pouring of the product and the closure of the container.
