Description

TECHNICAL FIELD

[0001] The present application relates to a topologically interlocking container, in particular to a topologically interlocking container. BACKGROUND

[0002] Containers, gas, liquid, solid containers. Among them, liquid containers are the most common, and their volume is divided into several categories as needed, most of which are circular, and occasionally square, hexagonal, etc., such as round cosmetic water bottles, round mineral water bottles, oval shampoo bottles, square milk boxes, small cylindrical yogurt boxes, water barrels, oil barrels, etc. Solid containers, according to the internal items, have various forms. Common boxes, most of which are square and round, occasionally have other shapes, such as medicine bottles, organizers, lunch boxes, and milk powder cans.

[0003] For ordinary bottles or containers:

[0004] Usually, the cross section is mainly circular, and the shape is mostly cylindrical, or slightly curved towards the center around the circumference, forming a shape similar to a jujube core. This form of container (bottle, milk box, can, barrel, etc.) When several identical containers are placed together, they have no complementary properties, so there is a lot of space between them. It occupies a lot of space, causing space waste and unsaturation of warehouse capacity.

[0005] When ordinary containers are placed together, the contact area between them is small, so the contact surface pressure is large, and they are prone to collision damage, or accumulation deformation, or static electricity, and if they are metal, they are prone to friction and sparks, which can cause a fire.

[0006] When ordinary containers are placed horizontally, each container has no restrictions in the horizontal and vertical directions between them, and they lack a certain dependence, so when they are stacked, the horizontal and vertical directions often shift and collide with each other, increasing the damage rate and accidents.

[0007] When several containers are stacked, they lack contact with each other, and often have to rely on sturdy and durable partitions and external boxes for packaging, or be bundled and bound one by one to ensure that each container does not slide and tilt too much relative to each other.

[0008] Therefore, the present application is proposed. SUMMARY

[0009] The present application aims to provide a topologically interlocking container to solve the above technical problems in the prior art.

[0010] The purpose of the present application is achieved by the following technical solutions:

[0011] The topological interlocking container of the present application is provided with a concave surface and / or a convex surface on the side of the container, and the convex surface and / or the concave surface of the adjacent container sides are complementary to each other, and one convex surface of each container corresponds to one concave surface of the adjacent container.

[0012] When the plurality of containers are arranged and placed, the adjacent sides of the plurality of containers are matched with each other, and the topological structure is formed in multiple directions.

[0013] Compared with the prior art, the topological interlocking container provided by the present application is designed to be topologically interlocked, mainly considering the fitting and inlaying between the containers, so that they can be completely matched when necessary, such as when packing, combining, transporting in large quantities, and the like, and after slightly applying pressure or fixing the outer ring range externally, the plurality of containers can be completely matched, and the plurality of containers form a rigid structure as a whole. The rigid structure is no longer loose, and each container is no longer completely independent, but they are tightly matched to form a firm whole. BRIEF DESCRIPTION OF DRAWINGS

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0034] First, the terms possibly used in the present text are described as follows:

[0035] The term "and / or" means either of the two or both at the same time, for example, X and / or Y means three cases including "X" or "Y" or "X and Y".

[0036] The terms “including,” “comprising,” “containing,” “having,” or other similar semantic descriptions should be interpreted as non-exclusive inclusion. For example, “including a technical feature element (such as raw material, component, ingredient, carrier, dosage form, material, size, part, component, mechanism, device, step, process, method, reaction conditions, processing conditions, parameter, algorithm, signal, data, product or article of manufacture, etc.)” should be interpreted as including not only the expressly listed technical feature element, but also other technical feature elements that are not expressly listed and are well-known in the art.

[0037] The term "composed of" excludes any technical features not expressly listed. When used in a claim, it closes the claim to exclude all technical features other than those expressly listed, except for associated conventional impurities. If the term appears only in a clause of a claim, it limits the claim to the elements expressly listed in that clause; elements recited in other clauses are not excluded from the overall claim.

[0038] Unless otherwise explicitly specified or limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this document according to the specific circumstances.

[0039] Terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," and "bottom"

[0040] The orientation or positional relationship indicated by terms such as "inner", "outer", "clockwise", and "counterclockwise" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of description and simplification, and does not explicitly or implicitly suggest that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this document.

[0041] The contents not described in detail in the embodiments of this invention are prior art known to those skilled in the art. Where specific conditions are not specified in the embodiments of this invention, they shall be performed according to conventional conditions in the art or conditions recommended by the manufacturer. Where the manufacturers of the reagents or instruments used in the embodiments of this invention are not specified, they are all conventional products that can be purchased commercially.

[0042] The topologically interlocked container of the present invention has a concave and / or convex side surface on the side of the container, and the convex and / or concave side surfaces of adjacent containers are complementary, with one convex surface of each container corresponding to one concave surface of the adjacent container.

[0043] When multiple containers are arranged in a row, their adjacent sides fit together, forming a topological structure in multiple directions.

[0044] The container has 4, 6, or 8 sides, in two alternate sets of sides:

[0045] A set of sides has an inward concave upper part forming a concave surface and an outward convex lower part forming a convex surface;

[0046] The upper part of the other side protrudes outward to form a convex surface, while the lower part is concave inward to form a concave surface.

[0047] The bottom surfaces of the convex and concave surfaces on each side are flat, and the bottom surfaces of the convex and concave surfaces form a trapezoid or inverted trapezoid as a whole.

[0048] Alternatively, the bottom surfaces of the convex and concave sides of each side are flat, and the width of the convex and concave sides decreases towards both ends from the middle of the bottle, forming a combination of a trapezoid and an inverted trapezoid.

[0049] The bottom surface of the concave surface is concave downwards to form a concave arc surface, and the bottom surface of the convex surface is convex upwards to form a convex arc surface.

[0050] When multiple containers on the four sides are arranged, they form a topological structure arranged in both longitudinal and transverse directions;

[0051] When multiple containers on the six sides are arranged, they form a honeycomb-like topological structure.

[0052] When multiple containers with four sides or multiple containers with eight sides are arranged at intervals, they form a topological structure with intervals in the longitudinal and transverse directions.

[0053] In summary, the topologically interlocked container of this invention utilizes the principle of topological interlocking. Each container's shape is no longer the traditional circle or square, but rather varies greatly; it can be a straight line cut like a diamond, or a combination of curved surfaces. Each container undergoes topological deformation, with its vertical cross-section constantly changing. When assembled, the containers can interlock and lock together. The container of this invention can hold low-pressure gases, liquids, and loose solids, with no gaps between each container, minimizing the unit volume. When several containers are assembled together, the contact area between them is large, resulting in a tight fit, low pressure, and a secure and safe connection.

[0054] To more clearly demonstrate the technical solution and its effects provided by the present invention, the embodiments of the present invention will be described in detail below with reference to specific examples.

[0055] Example 1

[0056] like Figures 1 to 17 As shown:

[0057] This invention utilizes the principle of topological interlocking to create a new container form that can interlock in several directions. The principle it employs is derived from topology.

[0058] This invention primarily focuses on containers for low-pressure gases, liquids, and loose solids. During large-scale storage or transportation, the shapes of these containers are generally not tightly interlocked, resulting in a small contact area and high pressure on the contact surfaces. This makes them prone to breakage, dents, or leaks. Furthermore, the lack of interlocking allows for displacement and friction, potentially generating static electricity or sparks, thus posing a hazard.

[0059] This invention employs the principle of topological interlocking, designing each container to have a unique shape. However, each container with the same shape has an inherent shape connection that allows them to interlock with each other. During stacking and transportation, they can maintain stability, prevent collisions and compression, and reduce mutual sliding to avoid potential dangers.

[0060] "Topological interlocking" incorporates two technical principles: "topology" and "interlocking." Mathematically, "topology" refers to a geometric object retaining certain original properties after continuous deformation. For example, the same species of fish may evolve into different shapes under different growing environments, but still belong to the same family. Such examples are ubiquitous in biology. In this invention, containers of different shapes are topologically the same object. They are all topological objects, like a sphere. "Interlocking" refers to the mutual restriction of relative motion between objects, achieving a relatively stable overall state. Combining these two technical principles means that a group of topologically identical unit containers, through their specific geometric shapes and arrangements, mutually restrict relative motion, achieving a relatively stable state for the cluster, where no single unit container can escape the cluster. Generally, the outermost units of the combined structure need to be fixed, forming a robust, enclosed loop to constrain and limit the internal containers, preventing them from loosening. Since containers are typically bundled together by manufacturers using packaging boxes or cable ties for centralized transportation, this outermost constraint cleverly acts as external pressure, causing all the internal containers to interlock with each other. Unlike conventional round or square containers, this invention does not require additional constraints or binding between each container, such as a grid-style packaging box that allows each container to be held individually.

[0061] In this invention, the convex and concave surfaces of adjacent containers are complementary, meaning they are arranged in a tessellated pattern, with their surfaces fitting together. One convex surface of each container corresponds to one concave surface of an adjacent container; the other direction of this container's convex surface is its concave surface (if this container is a square module, and the convex surface corresponds to the X-axis, then the Y-axis is its concave surface; if it is a hexagonal module, then the two directions are not 90 degrees from the coordinate axes, but 60 degrees, and so on). Adjacent modules of this module are opposite in this direction, with the convex surface corresponding to the concave surface and the concave surface corresponding to the convex surface. This achieves interlocking.

[0062] In this invention, taking container number 1 as an example, at the central waist position (basic shape) of the entire container, the horizontal cross-section of each container at this location is a regular hexagon. Several containers form a tessellated grid of hexagons, gradually changing upwards and downwards, that is, vertically. If the six sides of this hexagon are located as A, B, C, D, E, and F, then every other side A, C, and E form one group, and B, D, and F form another. When they gradually change upwards, the actions of each group are opposite in the vertical direction relative to the midpoint of the hexagon: if A, C, and E are compressed inwards towards the vertical central axis of the container, then B, D, and F are stretched outwards, and the shape and value of the amplitude are completely consistent; the shapes of the two are complementary. When the cross-section changes downwards, the opposite occurs: A, C, and E stretch outwards, while B, D, and F are compressed inwards. Therefore, the upper and lower cross-sections of the same container are complementary, and the cross-sections of two adjacent containers on the same horizontal plane are also complementary (see Figure "Topological Deformation Process of Hexagonal Prism in Container No. 1"). The above changes can also be made only in one vertical direction, such as upward or downward, which can also achieve interlocking. However, the shapes of the top and bottom surfaces are not complete and uniform, and the aesthetics are slightly lacking.

[0063] Therefore, the sides of the containers continuously develop slopes, creating concave and convex surfaces that interlock and lock together. This prevents the containers from moving vertically and also restricts their horizontal movement. Without external forces to wrap, restrict, or compress them, each container must move and be removed in a fixed horizontal direction to escape the group. Once an outermost horizontal restriction is applied to the entire container, each internal container also becomes interlocked in all horizontal directions. Container No. 2 and its variations operate on the same principle, the difference being that the horizontal cross-section at the center of the container is square or rectangular.

[0064] In this invention, the volume of the main body (excluding the nozzle) of containers 1 and 2 is the same as the volume of a prism of the same height formed by a polyhedral (basic shape) cross-section at the center of the container. For example, the volume of a regular hexagonal prism with a regular hexagonal cross-section as the basic shape of container 1 is: V = Sh, where S is the base area (area of ​​the hexagon) and h is the height. The area of ​​the regular hexagon S = 6 × the area of ​​the equilateral triangle = (3√3 / 2)a², where a is the side length of the regular hexagon. Therefore, the volume of each container after topological deformation is also this volume. For another example, the volume of a square prism with a square as the basic shape of container 2 is: V = Sh, where S is the base area (area of ​​the square) and h is the height. The area of ​​the square S = side length × side length = a × a (where a is the side length of the square). The volume of the square prism after topological deformation is the same as that of the square prism. The volumes of other topological containers with other basic shapes are calculated similarly. Therefore, the internal volume of the topologically interlocked containers of this invention can be calculated by subtracting the container wall thickness in this way.

[0065] In this invention, several other basic cross-sectional shapes can achieve topological interlocking and can be fabricated into containers. Even a matrix arrangement of circles can achieve interlocking through topological deformation (e.g., a circular cross-section in the middle waist and elliptical bottom surfaces). Many shapes in periodic and aperiodic tessellation can achieve topological interlocking. Specifically, for example, tessellation patterns formed by octagons and squares, but the containers they form are of two different shapes. For other more complex tessellation patterns, containers with topologically interlocking shapes often require more than two shapes. Due to topological deformation, the top and bottom surfaces of these shapes, if simply processed, often do not completely avoid the combination of the volume blocks at both ends and the recesses on both sides. The volume formula above does not apply in this case. Although this method has more contact surfaces between containers than ordinary containers, these recesses waste some volume; however, the container manufacturing process is significantly reduced, which is the method advocated by this invention.

[0066] Topologically interlocked unit containers have the characteristic of being able to move in small amplitudes within the kinematic constraints that enable interlocking. This characteristic can prevent the entire system from failing under the influence of high-amplitude vibrations and dissipated vibration energy. This is mainly because the mobility of the topologically interlocked structure absorbs some of the vibration energy. Therefore, such containers have excellent seismic performance.

[0067] Because each container undergoes topological deformation, its vertical cross-section is constantly changing. The concave and convex surfaces of adjacent containers correspond to each other. After assembly and fixing of the outer boundaries, the containers can interlock and lock together. It exhibits a stable state in both the horizontal and vertical directions.

[0068] The container employs the principle of topological interlocking, allowing for convenient and quick assembly and disassembly according to its directional shape. Once assembled, the overall stability is excellent. The topologically interlocked unit container possesses the characteristic of allowing small-amplitude movements within the kinematic constraints that enable interlocking. This characteristic prevents the entire system from failing under the influence of high-amplitude vibrations and dissipated vibrational energy. This is primarily because the mobility of the topological interlocking structure absorbs some of the vibrational energy, thus giving this container superior seismic performance.

[0069] In its structural principle, topological interlocking requires perimeter confinement or anchoring, eliminating the need for any rigid connections between the containers in the middle. The containers can then lock together and interlock without loosening. When assembled into a complete package, it exhibits excellent integrity and stability. This invention cleverly utilizes the external boundaries or pressure inherent in packaging materials such as boxes, straps, plastic films, and containers, which provide the necessary perimeter confinement, eliminating the need for partitions or straps between the containers.

[0070] The container of this invention can hold low-pressure gases, liquids, and loose solids, with liquids being particularly preferred. In terms of volume, small to medium-sized containers with relatively low overall pressure are recommended. Examples include plastic mineral water bottles, baby cartons, and grain and milk powder containers.

[0071] When several containers are placed together, the contact area between them is large, they fit together well, the pressure per unit area is small, and the combination is tight. It is not easy to slip or shift, nor is it easy to cause collision deformation or squeezing deformation. It is also not easy to generate frictional static electricity or sparks. The whole is stable, firm and safe.

[0072] The containers fit together tightly, thus maximizing the capacity per unit volume, or conversely, minimizing the total volume of several containers when holding the same quantity of the same liquid. This significantly saves space and storage area.

[0073] For container manufacturing, materials that can be shaped can be used, such as rigid cardboard, plastics, polymer resins, and metals. The manufacturing process for containers has relatively low requirements.

[0074] The containers possess unique forms, exhibiting both scientific rigor and aesthetic appeal. Some are straight lines resembling diamond-cut geometric shapes, while others are graceful, smooth forms combining curves and surfaces. They are charming and unconventional.

[0075] The inventive point of this invention lies in the container body, not in the container opening (such as the bottle neck or box opening). The container adopts a planar graphic design, which is composed of tessellated patterns. For example, square (rectangular) grids, hexagonal honeycomb grids, grids with alternating octagons and quadrilaterals, etc. These periodic or aperiodic tessellated patterns can be used as the original basic graphic for the topological deformation interlocking of this invention. Of course, if the original graphic is relatively complex, it will become more complex after topological deformation, increasing the types of interlocked containers and even causing them to vary in size.

[0076] These tessellation patterns are best implemented in a way that leaves no gaps on the plane itself, i.e., a full tiling. In this way, when viewed from the top view after topological deformation, the interlocking pattern will not have any through holes running vertically through the middle, thus maximizing the advantages of the invention.

[0077] Container No. 1 and its variants use a hexagon as the basic shape. In this invention, the hexagon can be a regular hexagon or a modified hexagon; however, from the perspective of container manufacturing and material conservation, a regular hexagon is recommended. Container No. 1 uses a hexagon as its basic plane, and in the vertical direction of this shape, it gradually changes upwards and downwards (it can also change on one side, but this is not shown in the figure; the shape coordination after a unilateral change is slightly worse). If the six sides of this hexagon are located as A, B, C, D, E, and F, they also have three axes. If the basic shape is a regular hexagon, then the angle between the three axes is 60 degrees. Each axis corresponds to two sides: one axis is A and D, one axis is B and E, and one axis is C and F. During topological deformation, the two sides on each axis move in unison, both moving and deforming in the same direction, defined as a distance L. Adjacent axes move at angles differing by 300 degrees, also with a distance of L. If we consider each side of the hexagon individually, then every other side (A, C, E) forms one group, and every other side (B, D, F) forms another. When they transition upwards, the actions of each group are opposite in the vertical direction relative to the midpoint of the hexagon: if A, C, E compress a vertical distance L inwards towards the vertical axis of the container, then B, D, F stretches outwards by a distance L, and the shape and value of the stretch are completely identical; their shapes are complementary. When the cross-section changes downwards, the opposite occurs: A, C, E stretches outwards by a distance L, while B, D, F compresses inwards by a distance L. Therefore, the upper and lower cross-sections of the same container are complementary, and the cross-sections of adjacent containers on the same horizontal plane are also complementary. Thus, the resulting container body or bottle has a side that gradually changes from convex to concave from top to bottom, and from concave to convex (see Figure "Topological Deformation Process of Container No. 1"). The degree of topological deformation during stretching has no absolute standard; the greater the deformation, the stronger the interlocking relationship, and the smaller the deformation, the weaker the interlocking relationship. However, excessive deformation, as shown in the far right of the image above, leads to excessive topological deformation, resulting in an increase in the container's surface area and making its manufacture overly complex. Therefore, it is necessary to consider factors such as the items to be contained, the ease of manufacturing the container, and the degree of material saving.

[0078] Container #1 can also be made into a curved shape. Curved shapes are more graceful and natural than straight shapes; straight shapes are simpler to manufacture than curved shapes. If it is transparent, straight shapes have a better effect of repeated refraction and crystalline clarity. Each has its advantages. The curves at the top and bottom of the surface can be achieved using arcs or other curves, such as quadratic curves. However, the curves at the edges of concave and convex surfaces must have a positive and negative shape relationship to achieve a perfect fit between the concave and convex surfaces of adjacent containers. The same manufacturing principle applies to containers #2, #3, or other topologically interlocking curved surfaces.

[0079] Container No. 2 and its curved surface shape are based on a rectangle (ideally a square). Container No. 2 uses the rectangle as its base plane, and in the vertical direction of this shape, it gradually changes upwards and downwards (it can also change on one side, but this is not shown in the diagram; the unilateral change results in a slightly less harmonious shape). If the four sides of this rectangle are designated A, B, C, and D, then every other side A and C form one group, and B and D form another. When they change upwards, the actions of each group are opposite in the vertical direction relative to the midpoint of the rectangle: if A and C compress inwards towards the vertical central axis of the container, then B and D stretch outwards, and the shape and magnitude of the stretch are completely consistent; their shapes are complementary. When the cross-section changes downwards, the opposite occurs: A and C stretch outwards, while B and D compress inwards. Therefore, the upper and lower cross-sections of the same container are complementary, and the cross-sections of adjacent containers on the same horizontal plane are also complementary. Thus, the resulting container body or bottle has a side that gradually changes from convex to concave from top to bottom, and vice versa.

[0080] The third set of containers consists of two shapes: a large octagonal container and a small rectangular container. If the octagon is a regular octagon, then the rectangle is a square. Their shape transformations follow a rule of alternating sides, with each side's inward (concave) or outward (convex) movement opposite to its adjacent side. The top and bottom edges also exhibit opposite concavity and convexity, and their shapes are complementary. The resulting octagonal and quadrilateral (rectangular) containers intertwine to form a perfectly fitting graphic, creating a highly aesthetically pleasing composition.
