Description

[0001] MULTIPURPOSE FLEXIBLE HERMETIC CONTAINER

[0002] FIELD OF INVENTION

[0003] The present invention relates to the field of mechanics, and more particularly to multipurpose airtight containers capable of storing liquids, solids, or gases under pressure. The container is manufactured from a flexible membrane such that, when empty, it can be compacted, folded, and rolled up, thus reducing its volume for transport or handling. The container can be used directly on the ground and outdoors, making it suitable for implementation in biodigester systems, water tanks, and other applications.

[0004] BACKGROUND

[0005] Today, as is well known, water scarcity is a significant problem in several regions, as rainfall patterns have been identified as changing, causing droughts to lengthen or shift to different areas. Protecting this resource is vital not only to reach more producers but also to support them. One way to mitigate this problem is by storing rainwater, primarily from the rainy season. Therefore, it is crucial to have the means not only to channel rainwater to a specific location but also to retain and store it for extended periods.

[0006] To achieve water storage in rural areas, many users opt for rigid water tanks, either closed or open. These rigid water tanks can be constructed on-site using building materials such as brick, steel, wood, cement, etc., which allows for large-capacity tanks with a long lifespan, but also comes at a high cost. Furthermore, the rigid tank remains permanently in place, even when empty. There are also other types of rigid water tanks available from catalogs, typically made of polymer. However, these prefabricated tanks are very expensive, and their volumetric capacity depends entirely on the size of the manufacturing facility. In other words, they have a capacity limit due to their manufacturing process, which is usually around 30,000 liters.Although these tanks can be moved when empty, their transportation is not simple, as they take up a lot of space, which increases implementation costs.

[0007] In this regard, several materials have been identified that can be used in the manufacture of water tanks and / or containers. These materials are resistant, easy to machine, and relatively inexpensive. They are typically used for water retention, but can also be used to store large quantities of fluids, as they are impermeable. Many of these materials are geomembranes, which are commercially available in sheet, continuous, and flexible form. They are used as an impermeable barrier against liquids or other fluids, specifically designed for UV exposure, and are made of synthetic polymer. Geomembranes are characterized by their mechanical strength, permeability, and durability in the environment.Thus, geomembranes are normally used in the manufacture of tanks or reservoirs for storing fluids, such as water or waste, where the tank is normally open, that is, an extensive layer of geomembrane is placed on the floor so that the liquid cannot permeate into the ground.

[0008] The use of geomembranes for the manufacture of biodigesters has also been identified. In this process, the geomembrane is used to construct the biodigester reactor, defined as a hermetically sealed container that stores organic matter. This container is subjected to constant pressure resulting from the biodigestion of said organic matter. This method yields good results as long as the biodigester reactor is at least partially supported by a trench that helps withstand the stresses to which the container is subjected. Among these reactors is the one developed under US patent 10,653,054 B2, which claims a biodigester reactor made from a flexible membrane material with a template of a specific shape. When these materials are joined to form the hermetically sealed container that constitutes the biodigester reactor, a final shape is created that reduces creases and increases its lifespan.However, for this reactor, the use of a trench is recommended for its installation. The trench, among other things, covers and contains the reactor, at least partially. Thus, although these reactors are designed to be flexible, pressure-tight vessels with an acceptable lifespan, when used directly on the ground, they can lose their shape due to stress in critical areas. Over time, with constant use, this results in uncalculated deformation of the vessel, reducing its lifespan and making it aesthetically unappealing.

[0009] Therefore, a need has been identified for developing flexible, watertight containers made from geomembrane, whose structure allows them to be used above ground while substantially maintaining their shape, without the need for trenching. Thus, a storage system for water or any other material—solid, liquid, and / or gas—is desirable if it allows for the use of trenches to contain the container, facilitating implementation, preventing deformation, and increasing the container's lifespan. Furthermore, it is known in the field that sheets of flexible material, such as the geomembrane commercially available, are offered in rolls that typically measure 6.87 ± 0.10 m wide by 200 m long, weighing approximately 1400 kg.Therefore, it is also desirable to develop methods and systems for manufacturing airtight tanks and / or containers based on these or other commercially available measures to optimize the material used, that is, to reduce waste.

[0010] Therefore, it is desirable to provide a hermetically sealed container made from sheets of flexible material capable of holding liquids, solids and / or gases, thus having different uses such as water storage, the storage of organic matter for a biodigester and / or for any other type of storage and / or retention.

[0011] SUMMARY

[0012] The present invention relates to methods, systems, devices and / or apparatus related to the storage of fluids and / or to the manufacture of flexible airtight containers that can be applied as storage tanks for large quantities of fluids, made from sheets of flexible material.

[0013] Techniques are provided for the fabrication of pressure-resistant and / or flexible fluid containment vessels made from sheets of flexible material joined in various patterns. The sheet may be a geomembrane with a thickness of 0.75 mm (30 mils), 1.0 mm (40 mils), 1.2 mm (48 mils), 1.5 mm (60 mils), 2.0 mm (80 mils), 2.5 mm (100 mils), 3.0 mm (120 mils), 6.0 mm (240 mils), and / or combinations thereof; or another equivalent material. The techniques provided for fabricating the flexible, watertight vessel involve one, two, or three templates of this material, which also include flexible structural elements that allow it to withstand stress, substantially maintaining its original shape and enabling the vessels to be placed on the ground, thus eliminating the need for trenching.Likewise, the flexible material sheet can be a geomembrane made from a material selected from the list of: linear polyethylene, either high or low density, linear polypropylene, either high or low density, bituminous elastomer, or polyvinyl chloride.

[0014] In this regard, a technician in the field will note that the pressure the container can withstand varies depending on the mechanical properties of the material, as well as the thickness of the flexible sheet or geomembrane used in its manufacture. Therefore, if greater pressure is required, a thicker sheet of flexible material is simply used, or a material with more suitable mechanical properties is selected. It is understood that with greater material strength, a thinner sheet can be used, and vice versa. The strength of the seams in the base must also be considered, as their strength is not necessarily the same as the strength of the material itself.

[0015] In this regard, in one embodiment of the invention, a sheet of flexible material of 1.25±0.1 mm is selected with an elongation capacity of at least 800%, a fracture resistance of at least 33kN / m, a tear resistance of at least 120N, as well as a puncture resistance of at least 310N.

[0016] In one embodiment of the invention, at least one template of flexible material is provided, wherein said at least one sheet is hermetically sealed at its edges or perimeter, thus forming a flexible, airtight container, which includes a container top and a container bottom, the latter being in contact with the floor. Likewise, in a preferred embodiment of the invention, the flexible, airtight container includes a plurality of straps attached thereto, wherein each strap is defined by at least one strip of flexible material whose dimensions depend on the dimensions of said at least one template. In one embodiment of the invention, the length of the strips of flexible material corresponds to the length of said at least one template, and the width of the strips is predetermined.Likewise, in one embodiment of the invention, one strip is overlapped with another strip of the same size, and they are joined to form a thicker strip, thus defining a tie rod. These tie rods, made of flexible material, are attached to the flexible sheet template so that when the resulting container is folded, emptied, or filled, the strips / tie rods also fold and adapt to the container. The tie rods are attached to the container either longitudinally (at least partially), transversely (at least partially), or in combinations thereof (at least partially), on one side of the template, the other side, or both sides. Therefore, the length of the tie rods that are attached longitudinally varies according to the longitudinal shape of the at least one template that forms the container.Likewise, the length of the transversely attached ties varies depending on the transverse shape of the at least one template that forms the container. The ties / ties can be straight, regularly curved, irregularly curved, with variable width, and / or combinations of these characteristics.

[0017] In one embodiment of the invention, the strips are cut to the corresponding dimensions based on a predetermined calculation. This calculation depends, among other factors, on the mechanical properties of the material, such as the geomembrane's strength, thickness, width, type of joint, and its connection to the template. In an alternative embodiment of the invention, the tie rods are defined by strips of plastic and / or metal mesh, which are cut to the corresponding dimensions based on a predetermined calculation. This calculation depends, among other factors, on the mechanical properties of the material, such as the mesh's strength, thickness, width, type of joint, and its connection to the template.

[0018] Thus, by attaching multiple flexible tie rods to the container, it can withstand greater stress while maintaining its predetermined shape (defined by at least one template) without the use of external retaining elements such as a trench. This characteristic, in turn, provides a variety of applications for the storage and / or retention of liquid, solid, and / or gaseous materials in different fields and / or techniques. For example, a flexible, airtight container with at least one inlet at the top and at least one outlet at the bottom can be used as a storage tank. When full, opening the outlet at the bottom will allow the stored material to flow out by gravity.In this same vein, an airtight container with at least one inlet and at least one outlet at the bottom (preferably at opposite ends of the container) and at least one outlet at the top can be used as a biodigester reactor that stores liquid and / or solid organic matter, as well as gases that rise to the top due to their density (such as biogas produced by the decomposition of organic matter). Thus, it has been identified that a flexible airtight container, such as the one disclosed in the present invention, will have different uses depending on the number, location, and / or size of the inlets and / or outlets attached. A person skilled in the art will note that the technique used to create the inlets and / or outlets can vary without affecting the subject matter of the present invention, provided that airtightness is maintained.Furthermore, a skilled technician will note that the components and / or accessories attached to said inlets and / or outlets for their operation may vary without affecting the subject matter of the present invention. Likewise, a skilled technician will note that the number of inlets and / or outlets in any area of ​​the lower and / or upper part of the container may vary to give the container a different use, without affecting the subject matter of the present invention.

[0019] In one embodiment of the invention, the container resulting from joining the edges of at least one flexible sheet template includes a shape that, in turn, includes a center of mass and / or a geometric center. The tie rods attached to said at least one template have a fixed separation distance between adjacent and parallel tie rods. In another embodiment of the invention, this separation distance is variable and changes as the tie rods approach the center of mass and / or geometric center of the container, such that the separation distance decreases as they approach said center. Likewise, in one embodiment of the invention, a failure analysis and / or a computer simulation, such as a finite element analysis, defines the areas of greatest stress in the container, such that the separation distance of the tie rods is smaller and / or decreases as they approach these areas of greatest stress.In this regard, a technician in the field will notice that the way to identify the areas of greatest stress in the container can vary without affecting the subject matter of the present invention.

[0020] In one embodiment of the invention, the upper part of the container, as well as the lower part of the container, are predetermined by the manufacturer.

[0037] DETAILED DESCRIPTION OF THE INVENTION

[0038] The following description is presented to enable any person skilled in the art to make and use the embodiments and is provided in the context of a particular application and its requirements. Several modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of this disclosure. Thus, the present invention is not limited to the embodiments shown; on the contrary, it should conform to the broader scope consistent with the principles and features disclosed herein.

[0039] Figure 1 shows two examples of a hermetically sealed container 12 made from two simple templates 12A and 12B of flexible sheeting, such as geomembrane, one oval and the other a rectangle with rounded corners. These templates are identical, and when one is placed on top of the other and hermetically sealed at their perimeters (shown as dashed lines), a bag is formed. By attaching inlets and / or outlets to this bag, different fluids / materials can be introduced, stored, and / or dispensed, thus defining a hermetically sealed container. A person skilled in the art will note that the shape of the fluid inlet and / or outlet of the container can vary without affecting the subject matter of the present invention. Fig. 2 shows several examples of containers 13 assembled from flexible sheet pieces, such as geomembrane, using at least three templates 13A, 13B and 13C, that is, a container 13 is assembled from three templates.In this respect, two identical templates are used for the ends 13A and 13B, and a rectangular template for the body 13C with height X and base Y measurements. By joining two parallel sides of the rectangular template 13C, a sleeve or cylinder is formed, which can be capped at its ends by joining the end templates 13A and 13B at their perimeters, thus forming the container 13. In this respect, the user defines a lower area that will be in contact with the ground 1000, so the container includes a top and a bottom part.In this sense, the templates of the ends 13A and 13B define the shape that the resulting prism or cylinder will have, which will define the container 13, which will have a height X but: with circular ends 13A and 13B that define a container in the shape of a right cylinder with a circular base; with elliptical or oval ends 13A and 13B that define a container in the shape of a right cylinder with an elliptical base or oval cylinder; with rectangular ends with rounded corners 13A and 13B, whether horizontal or vertical, that define a container in the shape of a rectangular prism with rounded corners; with triangular ends 13A and 13B, either with the different types of triangles, that defines a container in the shape of a triangular prism.In this regard, a person skilled in the art will note that the shape of the end templates 13A and 13B, which define the final shape of the container, can vary without affecting the subject matter of the present invention, and can be not only prisms but also pyramids. In one embodiment of the invention, the end templates 13A and 13B are not identical in dimensions and / or shape, and template 13B is not rectangular but rather a truncated triangle.

[0040] In this regard, the base or width Y of the rectangular template must correspond to the perimeter of the end templates 13A and / or 13B so that they can be joined accordingly. The points where the geomembrane templates are joined to form the container are shown with dashed lines. A joint is made in body 13C, which first forms the sleeve, and then templates 13A and 13B are joined to the ends of this sleeve, forming the closed container. A person skilled in the art will note that the technique for joining sections of flexible sheeting, such as geomembrane, with another of the same or compatible material may vary without affecting the subject matter of the present invention. Likewise, dimension X defines the height of either the cylinders or the prism or container examples 13 in Fig. 2.Also visible is the portion of container 13 that is in contact with the floor or ground 1000; that is, the lower part of container 13 is in contact with the floor 1000, thus defining a lower and upper portion of container 13 from three templates. Figure 3 shows a single template 11A for constructing a watertight container according to an embodiment of the invention, which, when its edges are joined in a specific way, forms a watertight container with straight ends (not shown in Figure 3). Thus, a template 11A is revealed with which, through different joints, cuts, and / or folds, a flexible watertight container is formed from geomembrane or flexible sheet material, which also prevents the formation of creases. Figure 3 shows an example that has been exaggerated from its exact dimensions for illustrative purposes.The template is formed from a rectangle AJWZ of flexible sheet or geomembrane, where cuts BCDE and FGHI are made to remove the quadrilaterals 50, where these cuts are made symmetrically on both sides of template 1 1 A (left and right according to the orientation of Fig. 3), however, for illustrative purposes only the cuts corresponding to the left side of template 1 1A are referred to. Thus, when the template is joined at its longest edge (segmented lines) a sleeve is formed including these cuts which, when joined in a specific way, produce a bag or container that when filled or inflated avoids the formation of folds such as those found in the technique.In one embodiment of the invention, the dimensions of cuts BCDE and FGHI (and their corresponding right-hand counterparts) vary depending on the dimensions of rectangle AJWZ, as well as the mechanical properties of the geomembrane material, such as dimensions, thickness, elastic properties, and / or the intended volumetric capacity of the container, etc. For example, it is more difficult for a manufacturer to perform the corresponding folds on a 6 mm thick flexible sheet material than on the same material that is 1.5 mm thick. These folds include those required for manufacturing and / or transporting the container, since the container must be deflated, folded, and / or transported, or dismantled to occupy the least possible space during transport or handling. In one particular embodiment of the invention, the dimensions of cuts BCDE and FGHI result in a rectangle measuring 50 x 100 cm.

[0041] In this sense, mechanical properties also include characteristics such as elastic properties of the material, thermal properties of the material, resilience, resistance, etc.

[0042] The distance EF is equal to the sum of the distances AB + IJ. The distance AB and the distance IJ may or may not be equal.

[0043] Thus, by joining the longer edges of the template or rectangle AJWZ (segmented line), a sleeve is formed that includes the previously defined cuts, such that elements AB and IJ, when joined, form element Bl. In one embodiment of the invention (not shown in the figures), the rectangle formed by the points

[0044] DEFG is cut to form a rectangle whose projection with respect to the body of the template is smaller.

[0045] In this regard, a method for joining template edges 11 A is included; the method includes the following steps:

[0046] Join element EF with element Bl, where point B is in direct contact with point E, and point F is in contact with I;

[0047] Join element CD with elements DE and BC accordingly;

[0048] Match element GH with elements FG and HI accordingly;

[0049] A person skilled in the art will notice that the method applies equally to the right-hand counterpart of template 11 A.

[0050] Likewise, a technician in the field will notice that there are different techniques for making cuts to the AJWZ rectangle to form the corresponding template, without affecting the subject matter of the present invention.

[0051] In one embodiment of the invention, the cuts are made after the sleeve has been formed, defined by joining the longer ends AZ and JW of the rectangle AJWZ. The different types of edges at each end, which will be joined to form the bag or container, are also visible.

[0052] Figure 4 shows a single template for constructing a watertight container according to an embodiment of the invention. When its ends are joined in a specific way, a watertight container with inclined or angled ends is formed (not shown in Figure 4). A template 11B is shown for manufacturing a watertight container, where the container has an angled shape. Starting with a rectangle AJWZ of geomembrane or flexible sheet material, the cuts shown BODE and FGHI are made (including the equivalent cuts shown in the figures on the right side of the template) to form quadrilaterals 50B, which include cuts with non-right angles Q. These non-right angles vary depending on the final capacity of the watertight container, the mechanical properties of the geomembrane material, the location where the container is installed (whether or not trenches are used), or other factors.In one embodiment of the invention, the dimensions of these cuts and the angle vary and depend on the original dimensions of rectangle AJWZ and the intended final shape of the reactor. Specifically, the vessel becomes wider at the bottom (relative to the top or opposite side) as angle Q approaches 0. s In order to more evenly distribute the stresses generated by the accumulation of liquid / solid and / or denser waste at the bottom of the reactor. The distance EF is equal to the sum of the distances AB + IJ. The distance AB and the distance IJ may or may not be equal.

[0053] Thus, by joining the longer edges of the template or the rectangle AJWZ (dotted line) a sleeve is formed that includes the previously defined cuts so that the elements AB and IJ, after this joining, become the element Bl.

[0054] Figure 4 also shows the midlines M of quadrilaterals 50 along which the sleeve folds will be made. Thus, once the geomembrane sleeve is folded along the midlines of the quadrilaterals, it is possible to join these quadrilaterals to form the reactor that avoids the folds.

[0055] In this regard, a method for joining template edges 1 1 B is included; the method includes the following steps:

[0056] For the lower left quadrilateral:

[0057] Form a sleeve by joining line AZ with line JW;

[0058] Join line CD with the adjacent line DE, partially sealing the sleeve;

[0059] Join line EF with line AB + IJ accordingly;

[0060] A person skilled in the art will note that the method applies equally to each other quadrilateral of template 1 1 B. Likewise, a person skilled in the art will note that there are different techniques for making the cuts to remove the quadrilaterals 50B. In this regard, in one embodiment of the invention, the cuts are made before the sleeve has been formed. In another embodiment of the invention, the cuts are made after the sleeve has been formed.

[0061] Figure 5 shows an alternative embodiment of the template in Figure 4, where the resulting container also has inclined ends. Within dotted boxes, the areas corresponding to the upper portion 11D and the lower portion 11U of the container are shown, and these areas are predefined. A person skilled in the art will note that these same areas apply to the other single-template containers shown in Figure 3. Furthermore, a person skilled in the art will note that area 11D can correspond to the lower portion of the container and area 11U can correspond to the upper portion of the container without affecting the subject matter of the present invention.

[0062] Figure 6 shows a template of the type 11A shown in Figure 3 with straight cuts. The rectangular section 1 of flexible sheet material, such as geomembrane, is visible, with a length X and a width Y. This rectangular section 1 can be cut from the commercially available geomembrane roll. From this rectangular section 1, rectangular cuts 50 are made to form template 11A. Once these rectangular cuts 50 are made, each end of template 11A is defined, including end edges 51A and 51B (in Figure 6, these elements are only identified at one end of template 11A, but they are applied equally and symmetrically to the other end). Thus, once the sleeve is formed, end edges 51A will be joined together, and end edges 51B will also be joined together.In a particular embodiment of the invention, the 50 squares have dimensions of 50x50 ±10 cm.

[0063] Figure 7 shows a top view of a container 11 formed from template 11A shown in Figure 6, where the edges have already been joined and the container is empty (deflated), thus defining a container with minimal volume that occupies less space, compacted and folded symmetrically to be rolled up for transport or storage. Figure 7 does not show the joining of the template that forms the sleeve. Thus, Figure 7 shows the container 11 formed from template 11A, where the end edges 51A are joined together and the end edges 51B are joined together. In this respect, it can be seen how the joined end edges 51B form a resultant line longitudinal to the length X1 of the container. In contrast, the joined end edges 51A form a resultant line transverse to the length X1 of the container.Figure 7 shows a top view of the bag formed from the template in Fig. 6, i.e., it defines the container 1 already formed from the template in Fig. 6.

[0064] Figure 8 shows a perspective view of the container 11 shown in Figure 7 in a full or inflated position. The end edges 51A and 51B, already joined, are also visible in this inflated position. Figure 8 does not show the joint made in template 11A to form the sleeve. The lower part of the container in contact with the ground 1000 is also visible.

[0065] Figure 9 shows a perspective view (simulated and actual image) of container 11, formed from template 11A, where the container is subjected to stress, either through a computer simulation (left) using the finite element technique, or in reality through the introduction of a fluid such as water (right). Figure 9 shows both examples, simulation and actual image, where the deformations due to the stresses are visible, and where these stresses are identified and located. In this sense, the areas of greatest stress usually coincide with areas where planes intersect the center of mass and / or geometric center of the container; however, they can also be located in other areas of the container, such as the vertices and / or sides. Thus, the areas of greatest stress are identified.

[0066] Figure 10 shows a perspective view of an exemplary type of vessel assembled / constructed from either one template 11, two templates 12, or three templates 13, as previously shown, where at least one longitudinal support tie 21 and at least one transverse support tie 22 have been attached. These tie rods are made of flexible sheet material, such as the geomembrane from which the corresponding template(s) are made. These tie rods 21 and 22 are attached to the internal and / or external surface of the vessel to provide additional support. Longitudinal tie rods 21 and transverse tie rods 22 are provided, and these tie rods can be positioned at an angle, at least partially.In this regard, the number and spacing of the longitudinal ties 21 and / or transverse ties 22 may vary depending on the dimensions of the container, the product to be stored, the mechanical properties of the flexible sheet material from which the container is made, as well as the mechanical properties of the material of the ties 21 and / or 22, and / or combinations thereof. For this purpose, at least one mechanical property is selected from the following list: thickness, overall dimensions, Young's modulus, density, hardness, strength, resilience, etc. Furthermore, the container has at least one inlet 30 for introducing solid, liquid, and / or gaseous material, and at least one outlet 31 for removing said material.

[0067] Figure 11 shows a template of type 11A for manufacturing a flexible, airtight container from a single template, to which a plurality of longitudinal tie rods 21 are attached. Each tie rod 21 is separated from the others by a separation distance 21D. Furthermore, each tie rod has a predetermined length and width. In one embodiment of the invention, the length of each longitudinal tie rod 21 is substantially equal to the length of the template 11A. Also, in another embodiment, the width of each longitudinal tie rod 21 and / or the separation distance 21D between one longitudinal tie rod and an adjacent one varies according to the design capabilities of the container. In a particular embodiment, the separation distance 21D is fixed at 30 cm ± 10 cm.In one particular embodiment of the invention, the separation distance 21D is not fixed along the entire template 11A. This separation distance 21D decreases as it approaches the geometric center of mass of a container 11 (not shown in Fig. 11) resulting from template 11A, and increases as it moves away from the geometric center of mass of the container. In one particular embodiment, the longitudinal ties 21 have a fixed width of 30 cm ± 10 cm. In another particular embodiment, the longitudinal ties 21 have a variable width, increasing as they approach the geometric center of mass of the container and decreasing as they move away from the geometric center of mass of the container. Furthermore, in one embodiment, the material used to manufacture each ties 21 is the same as the material used to manufacture template 11A.In one embodiment of the invention, the thickness of the flexible sheet from which each longitudinal tie 21 is manufactured is equal to or greater than the thickness of the flexible sheet from which the template 11A is manufactured. Furthermore, the longitudinal tie 21 can be attached to the template 11A, either on its inner face, its outer face, and / or combinations thereof. In a particular embodiment of the invention, several tie 21 are stacked one on top of the other and joined to form thicker tie rods. In another embodiment, at least two tie rods are stacked one on top of the other and joined. In yet another embodiment, a thicker flexible sheet is used to form the longitudinal tie rods 21.Furthermore, the length of the longitudinal ties 21 can vary in order to cover most of the length of the template 11A, as is the case with tie 21L, which is slightly longer than the other longitudinal ties 21. This is to adapt to the different lengths of the template 11A and cover its surface, at least partially. Likewise, a person skilled in the art will note that the material from which the longitudinal ties 21 are manufactured can vary without affecting the subject matter of the present invention. It can be the same material, a metal mesh, and / or a mesh of another material, provided that the material is compatible in terms of mechanical properties, as well as fusion and / or bonding properties, with the flexible sheet material from which the template 11A is manufactured, such as a geomembrane.In one embodiment of the invention, the longitudinal braces 21 that remain in a lower part of the container, i.e., attached to the floor, are located on the outer face of the container and where said lower part of the container is predetermined.

[0068] Figure 12 shows a template of type 11A, to which a plurality of transverse tie rods 22 are attached. Each tie rod 22 is separated from the others by a separation distance 22D. Each tie rod also has a predetermined length and width. In one embodiment of the invention, the length of each transverse tie rod 22 is substantially equal to the transverse length of the template 11A. Furthermore, in another embodiment, the width of each transverse tie rod 22 and / or the separation distance between transverse tie rods 22 varies according to the design capabilities of the vessel. In a particular embodiment, the separation distance 22D is fixed at 30 cm ± 10 cm. In another particular embodiment, the separation distance 22D is not fixed along the entire template 11A, being smaller or decreasing as it approaches the geometric center of mass of a vessel 11 (not shown in Figure 12).1 1 ) resulting from template 1 1 A, and this separation distance 22D being greater or increasing as it moves away from the center of mass / geometric center of the container. In one particular embodiment of the invention, the transverse ties 22 have a fixed width of 30cm ±10cm. In another particular embodiment, the transverse ties 22 have a variable width, this width being greater or increasing as it approaches the center of mass / geometric center of the container and being less or decreasing as it moves away from the center of mass / geometric center of the container. Likewise, the material from which each tie 22 is made is the same as the material from which template 1 1 A is made. In another embodiment, the thickness of the flexible sheet from which each transverse tie 22 is made is equal to or greater than the thickness of the flexible sheet from which template 1 1 A is made.Furthermore, the transverse braces can be attached to the insole 11A, either on its inner face, its outer face, and / or combinations thereof. In one particular embodiment of the invention, several braces 22 are overlapped and joined to form thicker braces. In another embodiment, at least two braces are overlapped and joined. In yet another embodiment, a thicker flexible sheet is used to form the transverse braces 22. The length of the transverse braces 22 can also be varied to cover most of the transverse length of the insole 11A, that is, to adapt to the different transverse lengths of the insole 11A, as is the case with the transverse brace sections 22S, which are adapted to cover most of the transverse portion of the insole 11A.Furthermore, a person skilled in the art will note that the material used to manufacture the transverse ties 22 can vary without affecting the subject matter of the present invention. It can be the same material, a metal mesh, and / or a mesh of another material, provided that the material is compatible in terms of mechanical properties, as well as fusion and / or bonding properties, with the flexible sheet material used to manufacture the template 11A, which can be geomembrane material. In one embodiment of the invention, the transverse ties 22 that are located at the bottom of the container, i.e., attached to the floor, are positioned on the outer face of the container, where said bottom of the container is predetermined by the manufacturer.

[0069] Figure 13 shows a template of type 11A, which creates a container from a single template, to which straps of types 21 and 22 have been attached. The method of attaching these straps can vary, either stacked one on top of the other or interwoven in different ways, depending on convenience and / or utility. A person skilled in the art will note that the way in which the longitudinal straps 21 are woven with the transverse straps 22 can vary without affecting the subject matter of the present invention. Furthermore, although the figures show longitudinal straps 21 and transverse straps 22, in one embodiment of the invention, template 11A includes inclined straps (not shown in the figures). In one embodiment of the invention, template 11A includes longitudinal straps, transverse straps, inclined straps, and / or combinations thereof.Furthermore, in one embodiment of the invention, the separation distance of the longitudinal ties 21D is equal to the separation distance of the transverse ties 22D. In an alternative embodiment of the invention, the separation distance of the longitudinal ties 21D is greater than the separation distance of the transverse ties 22D. In another alternative embodiment, the separation distance of the longitudinal ties 21D is less than the separation distance of the transverse ties 22D. Accordingly, in one embodiment, the length-to-width ratio of the longitudinal ties is equal to the length-to-width ratio of the transverse ties. In an alternative embodiment, the length-to-width ratio of the longitudinal ties is greater than the length-to-width ratio of the transverse ties.In an alternative embodiment of the invention, the length-to-width ratio of the longitudinal ties is less than the length-to-width ratio of the transverse ties. In one particular embodiment, the separation distance of the longitudinal ties 21D from the longitudinal ties is 20 ± 10 cm. In another particular embodiment, the separation distance of the transverse ties 22D from the longitudinal ties is 155 ± 10 cm. Also, in another particular embodiment of the invention, the length-to-width ratio of the longitudinal ties is 30 ± 10 cm and the length-to-width ratio of the transverse ties is 30 ± 10 cm.

[0070] A technician in the field will note that the technique of using longitudinal ties 21 as well as transverse ties 22 applies equally to containers that are manufactured from one template 1 1 , two templates 12 and / or three templates 13.

[0071] Figure 14 shows a container 11 in its deflated or empty state, flattened and symmetrically folded at its ends, as shown in Figure 7, where a plurality of container inlets 30 and / or container outlets 31 have been included. In this respect, the quantity, shape, location, and / or dimensions of these inlets 30 and / or outlets 31 may vary depending on the application of the flexible airtight container 11, without affecting the subject matter of the present invention, provided that the airtightness of said container 11 is maintained when these inlets 30 and / or outlets 31 are in a closed state. The inlets 30 and / or outlets 31 have different applications, such as inlet and / or outlet of the stored fluid, as well as a vent during filling, etc.

[0072] Figure 15 shows a container 11 in its deflated or empty state, flattened and symmetrically folded at its ends, as shown in Figure 7. Corner supports 45, defined by rhomboid-shaped templates, are included at the corners of the container 11. These corner supports 45 are made of the same flexible sheet material as the container 11 or a compatible material, and can be of the same or greater thickness. To achieve greater thickness, several rhomboid corner support templates 45 are placed one on top of the other and joined at each corner of the container 11.

[0073] Figure 16 shows a perspective view of a container 11 already filled with some product, whether solid, liquid, and / or gaseous, where said container 11 includes at least one outlet 31 at the bottom of said container 11, at least one inlet 30 at the top of the container 11, where inlet extensions 30E have been included to increase the height from which the container 11 is filled. Also visible are the rhomboid-shaped corner supports 45.

[0074] Although this document specifies that a commercially available geomembrane is being used, a skilled technician will note that the same novelty and inventiveness apply to any equivalent flexible sheet material.

[0075] A technician in the field will notice that the measurements and shapes shown in this document are ideal cases, since the final product of the container once filled with some product or material inside said container will have a rounded and / or approximate shape at its vertices / sides, where the heavier products will settle, potentially deforming the lower part of the container and leaving the less dense products at the top of the container.

[0076] A method for manufacturing containers from a rectangular sheet of flexible material is also disclosed. The method comprises the following steps:

[0077] Starting with a rectangular sheet made of a flexible sheet material, fold the first two parallel sides toward the central axis parallel to those sides, forming an apparent sleeve without joining. Once the apparent sleeve is formed, cut off the four corners of said apparent sleeve, where said cuts are in the shape of quadrilaterals 50, which have a longitudinal width 50X and a transverse length 50Y of quadrilateral 50. In one embodiment of the invention, said corner cuts of the apparent sleeve in the shape of quadrilaterals measure 50 cm for 50X and 50 cm for 50Y. In an alternative embodiment of the invention, said corner cuts of the apparent sleeve in the shape of quadrilaterals measure 25 cm for 50X and / or 25 cm for 50Y. However, a person skilled in the art will note that these measurements may vary according to the original template and / or the final dimensions of the container without affecting the subject matter of the present invention.Once the quadrilaterals have been cut in the apparent sleeve, extend again the first parallel sides that were folded so that now the entire sheet of flexible material is extended with the previously made cuts, thus defining a first template, so that now when extended, the resulting quadrilateral has a measurement of (50X x 2) x 50Y.

[0078] On a second rectangular sheet made of flexible material, cut a plurality of strips with a length corresponding to the width and length of the first rectangular sheet, thus defining transverse strips (corresponding to the width of the first sheet, at least partially) and longitudinal strips (corresponding to the length of the first sheet, at least partially). The width of the flexible material strips is predetermined. Overlap at least one strip of the same size on top of another, thus defining a tie rod, so that there are longitudinal and transverse tie rods. Place the longitudinal and / or transverse tie rods on the first template, so that each tie rod is separated from an adjacent and parallel tie rod by a predetermined distance and so that it uniformly covers, at least partially, the first template.In one embodiment of the invention, the spacing between adjacent and parallel braces is 20 cm. In a particular embodiment, the spacing between adjacent and parallel braces is 30 cm. In an alternative embodiment, the spacing between adjacent parallel braces varies according to their location on the first plate, decreasing as they approach either the geometric center, the center of mass, and / or a predetermined area, such as a stress concentration zone. In one embodiment, the longitudinal and transverse braces are placed on the first plate in an interlocking manner.

[0079] In one embodiment of the invention, the joining technique for: the flexible material strips; the braces to the container; the containers made from one, two, or three templates; and / or combinations thereof, depends on the selected material, but particularly the heat-fusion technique already known in the art is used. In one embodiment of the invention, the welding technique is used, where there is a filler material known in the art and which depends on the membrane material. In one embodiment of the invention, the heat-fusion and / or welding technique is used. In this regard, a person skilled in the art will note that other joining and / or welding techniques can be applied to the present invention without affecting the material. Likewise, in one embodiment of the invention, a greater amount of filler material is used in the joint resulting at the corners or vertices, in order to withstand the stresses that are concentrated there.

[0080] In one modality of invention, the joints in the containers, whether from one, two or three templates, are made using the technique of extrusion welding, wedge welding, electrofusion welding and / or combinations of these, where there is or is not filler material.

[0081] A person skilled in the art will notice that the airtight container, made from one, two, or three templates, may include accessories such as at least one inlet and / or outlet through holes drilled in the template. The technique for drilling the hole, as well as the technique for regulating and / or temporarily and / or partially covering said inlet and / or outlet, may vary in shape, dimensions, and / or capacity, without affecting the subject matter of the present invention. These accessories may include valves of different sizes and types, snap-on caps of different sizes and types, flanges of different sizes and types, threaded caps of different sizes and types, water seals of different sizes and types, relief valves of different sizes and types, emergency valves of different sizes and types, etc.In one embodiment of the invention, the flexible airtight container is used as a storage tank that includes at least one outlet at the bottom of the container and at least one inlet at the top of the container.

[0082] In one embodiment of the invention, the flexible, airtight container is used as a biodigester reactor, including at least one inlet and at least one outlet at the bottom of the container, and at least one outlet at the top of the container. In a particular embodiment, the at least one inlet and the at least one outlet at the bottom of the container are sealed by means of a water seal.

[0083] Thus, a hermetically sealed container is claimed, manufactured from at least one sheet of flexible material, comprising: at least a first template of flexible material sheet including a first template width and length, and wherein the first template includes an inner face and an outer face; at least one longitudinal tie defined by at least one strip of flexible material sheet including a longitudinal tie length and a longitudinal tie width, the longitudinal tie being longitudinally attached either to the inner face and / or the outer face of the first template, and wherein each longitudinal tie is separated from at least one other adjacent longitudinal tie by a longitudinal tie separation distance;and at least one transverse tie defined by at least one strip of sheet material of flexible material including a transverse tie length and a transverse tie width, the transverse tie being attached transversely to either the inner face and / or the outer face of the first template, and wherein each transverse tie is separated from at least one other adjacent transverse tie by a transverse tie separation distance; wherein the first template is folded and tightly joined around its contour thus forming a closed container including a lower container portion in contact with the ground and an upper container portion, wherein the length of: the longitudinal tie width, the transverse tie width, the longitudinal tie separation distance and / or the transverse tie separation distance, are predetermined;and wherein the container includes at least one perforation in the bottom of the container and at least one perforation in the top of the container.;

[0084] A system and / or method for manufacturing a flexible airtight container from at least a first template of flexible sheet material is also claimed, the system comprising: means for attaching to the first template at least one longitudinal tie defined by at least one strip of flexible sheet material including a longitudinal tie length and a longitudinal tie width, the longitudinal tie being attached longitudinally either to the inner face and / or the outer face of the first template, and wherein each longitudinal tie is separated from at least one other adjacent longitudinal tie by a longitudinal tie separation distance;means for attaching to the first template at least one transverse brace defined by at least one strip of flexible sheet material including a transverse brace length and a transverse brace width, the transverse brace being attached transversely either to the inner and / or outer face of the first template, and wherein each transverse brace is separated from at least one other adjacent transverse brace by a transverse brace separation distance; and means for hermetically sealing the template around its perimeter, thereby forming a closed container including a lower container portion in contact with the ground and an upper container portion.

[0085] Similarly, a method is claimed for manufacturing a watertight container from a rectangular template of geomembrane, the method comprising the steps of: making cuts, on a first pair of opposite ends of rectangular template, to remove geomembrane forming two quadrilaterals for each said opposite end, wherein each quadrilateral includes two first sides that are non-consecutive and parallel which in turn are parallel to a second pair of opposite ends of rectangular template and a third side that is orthogonal to the first two sides that are non-consecutive and parallel which lies on a corresponding edge of rectangular template, and wherein a separation distance between said quadrilaterals is the same distance as the sum of the separation distances between each quadrilateral and a nearest end of the second pair of ends of rectangular template;Join one edge of one end of the second pair of rectangular template ends to one edge of the other end of the second pair of rectangular template ends, thus forming a sleeve; join each quarter side of a quadrilateral to an adjacent side of a quarter side, so that an adjacent side of one quadrilateral is closest to an adjacent side of another quadrilateral, thus partially sealing the sleeve; and join the remaining edges of the first pair of opposite ends, thus fully sealing the sleeve.

[0086] The preceding descriptions of various embodiments have been presented for illustrative and descriptive purposes only. They are not intended to be exhaustive, nor are they intended to limit the present invention to the disclosed forms. Consequently, many modifications and variations will be evident to those skilled in the art. Furthermore, the foregoing disclosure is not intended to limit the present invention.
