Description

Technical Field

[0001] This disclosure belongs to the field of packaging technology, specifically relating to a three-dimensional liquid bag and packaging structure. Background Technology

[0002] Current liquid bags are typically pillow-shaped structures. When placed in a turnover box, the pillow-shaped liquid bag does not fit well against the inner wall of the turnover box, affecting the effective utilization of the liquid bag's volume and making it prone to damage during transportation. Some liquid materials may accumulate significant sediment in the liquid bag during storage and transportation, requiring thorough mixing before downstream extraction. Pillow-shaped liquid bags and filling port structures are not suitable for thorough mixing. Utility Model Content

[0003] The purpose of this application is to provide a three-dimensional liquid bag and packaging structure that can enhance the fit between the three-dimensional liquid bag and the inner wall of the box when the three-dimensional liquid bag is placed inside the box, and facilitate the full stirring of liquid materials in the containment space.

[0004] This disclosure provides a three-dimensional liquid bag, which is placed inside a box, and the three-dimensional liquid bag includes: The cylindrical body is hollow inside; the cylindrical body can fit against the inner wall of the box body. A bottom cover is disposed at the bottom of the cylinder body. The bottom cover is connected to the bottom edge of the cylinder body and can be folded relative to the cylinder body to seal the bottom opening of the cylinder body. The bottom cover can fit against the inner bottom wall of the box body. A top cover is disposed on the top of the cylinder, the top cover is connected to the top edge of the cylinder, and can be folded relative to the cylinder to seal the top opening of the cylinder; the top cover, the cylinder, and the bottom cover enclose a sealed receiving space; the top cover is provided with a cutting line, the cutting line being located on the side of the top cover away from the top edge of the cylinder, so as to expose the top opening of the cylinder by cutting the top cover along the cutting line; A filling component is disposed on the top cover, and the filling component is provided with a filling port communicating with the receiving space.

[0005] In one exemplary embodiment of this disclosure, the cylindrical body is in the shape of a quadrangular prism, and the cylindrical body includes four side plates connected end to end; The top cover includes four top sections, which are connected one-to-one with the top edges of the four side plates. The top sections can be folded relative to the side plates. The filling component is disposed on one of the top sections.

[0006] In one exemplary embodiment of this disclosure, the top portion includes a top cover plate in the shape of an isosceles triangle, with adjacent edges of two adjacent top cover plates abutting each other; the filling component is disposed on the top cover plate.

[0007] In one exemplary embodiment of this disclosure, the top section includes top folding plates arranged on both sides of the top cover plate. There is a crease between the top folding plate and the top cover plate, and the crease between the top folding plate and the top cover plate coincides with the adjacent edge between two adjacent top cover plates. When the top cover seals the top opening of the cylinder, the top folding plate is symmetrically folded and attached to the top cover plate, and the top folding plate is spaced apart from the filling port.

[0008] In an exemplary embodiment of this disclosure, the top folding plate includes a top folding edge and a top fitting edge. The top folding edge is connected to the top cover plate, and the remaining edges of the top folding plate are the top fitting edges. The top fitting edges of the two top folding plates on the adjacent edges of two adjacent top cover plates are fused one-to-one to form a top sealing channel. The shear line is located on the side of the top segment away from the corresponding side plate, and the shear line is parallel to the top edge of the corresponding side plate.

[0009] In one exemplary embodiment of this disclosure, the cylindrical body is in the shape of a quadrangular prism, and the cylindrical body includes four side plates connected end to end; The bottom cover includes four bottom pieces, which are connected one-to-one with the bottom edges of the four side plates. The bottom pieces can be folded relative to the side plates.

[0010] In one exemplary embodiment of this disclosure, the bottom portion includes a bottom cover plate in the shape of an isosceles triangle, with adjacent edges of two adjacent bottom cover plates abutting each other.

[0011] In one exemplary embodiment of this disclosure, the bottom section includes bottom folding plates arranged on both sides of the bottom cover plate. There is a crease between the bottom folding plates and the bottom cover plate, and the crease between the bottom folding plates and the bottom cover plate coincides with the adjacent edge between two adjacent bottom cover plates. When the bottom cover seals the bottom opening of the cylinder, the bottom folding plates are symmetrically folded to fit against the bottom cover plate.

[0012] In an exemplary embodiment of this disclosure, the bottom folding plate includes a bottom folding edge and a bottom fitting edge. The bottom folding edge is connected to the bottom cover plate, and the remaining edges of the bottom folding plate are the bottom fitting edges. The bottom fitting edges of the two bottom folding plates on the adjacent edges of two adjacent bottom cover plates are fused together to form a bottom sealing channel. The adjacent edges of two adjacent bottom cover plates are fused together to ensure that the space between the two fused bottom folds is not connected to the receiving space.

[0013] In one exemplary embodiment of this disclosure, the filling component includes: The base is mounted on the top cover, and the filling port is provided on the base. A filling connector is hollow inside and open at both ends. The filling connector is located outside the receiving space. The bottom surface of the filling connector is connected to the top surface of the base bottom, and its bottom opening communicates with the filling port. The inner side of the filling connector is provided with a threaded groove. A sealing cap has threads on its outer periphery to connect with the inner side of the filling connector, thereby sealing the filling port.

[0014] This disclosure also provides a packaging structure, including a box and a three-dimensional liquid bag as described above, wherein the box is hollow inside and open at the top, and when the three-dimensional liquid bag is placed inside the box and the three-dimensional liquid bag is filled with liquid material, the outer surface of the three-dimensional liquid bag is in contact with the inner wall of the box.

[0015] The technical solutions provided in this disclosure have at least the following advantages: The embodiments disclosed herein achieve sealing of the top and bottom openings of the cylinder by providing a top cover and a bottom cover at the top and bottom of the cylinder respectively, and enabling the top cover and bottom cover to fold relative to the cylinder, thereby forming a containment space capable of containing liquid materials.

[0016] In this embodiment, a shearing line is provided on the top cover. The top cover can be folded over and cut along the shearing line to expose the top opening of the cylinder. This allows the stirring tool to be easily inserted into the containing space and the liquid material in the containing space to be fully stirred, thereby improving the problem of uneven unloading of liquid material caused by a large amount of sedimentation in the three-dimensional liquid bag.

[0017] This embodiment of the invention provides a filling component on the top cover. During unloading, a stirring tool can be inserted into the containing space through the filling port on the filling component to fully stir and mix the liquid material in the three-dimensional liquid bag. This can improve the problem of uneven unloading of liquid material caused by a large amount of sedimentation in the three-dimensional liquid bag.

[0018] Furthermore, by providing a top cover and a bottom cover at the top and bottom of the cylinder, the structural strength of the three-dimensional liquid bag can be enhanced. When the three-dimensional liquid bag in this embodiment is placed inside the box, the cylinder can fit against the inner wall of the box, and the bottom cover can fit against the inner bottom wall of the box. This can enhance the fit between the three-dimensional liquid bag and the inner wall of the box, thereby increasing the utilization rate of the three-dimensional liquid bag to the internal volume of the box and reducing the risk of the three-dimensional liquid bag shaking violently and breaking during transportation.

[0019] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.

[0020] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0038] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art.

[0039] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0040] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0041] Current liquid bags are typically pillow-shaped bags made by bonding two pieces of material together and heat-sealing them around the perimeter. These pillow-shaped liquid bags usually have problems such as poor adhesion to the inner wall of the container, low effective utilization of the internal space of the container, and difficulty in fully agitating the liquid material inside the bag.

[0042] like Figure 1 As shown, this disclosure provides a three-dimensional liquid bag 100, which may include: a cylindrical body 1, a bottom cover 3, a top cover 2, and a filling component 4. The cylindrical body 1 is hollow inside. The bottom cover 3 is disposed at the bottom of the cylindrical body 1 and connected to the bottom edge of the cylindrical body 1. The bottom cover 3 can be folded relative to the cylindrical body 1 to seal the bottom opening of the cylindrical body 1. The top cover 2 is disposed at the top of the cylindrical body 1 and connected to the top edge of the cylindrical body 1. The top cover 2 can be folded relative to the cylindrical body 1 to seal the top opening of the cylindrical body 1. The top cover 2, the cylindrical body 1, and the bottom cover 3 can form a sealed containing space. The top cover 2 is provided with a cutting line 23, which is located on the side of the top cover 2 away from the top edge of the cylindrical body 1, so as to expose the top opening of the cylindrical body 1 by cutting the top cover 2 along the cutting line 23. The filling component 4 is disposed on the top cover 2 and is provided with a filling port communicating with the containing space.

[0043] In this embodiment, a top cover 2 and a bottom cover 3 are respectively provided at the top and bottom of the cylinder 1, and the top cover 2 and the bottom cover 3 can be folded relative to the cylinder 1 to seal the top opening and the bottom opening of the cylinder 1 and to form a containment space that can contain liquid materials.

[0044] This embodiment of the present disclosure provides a shearing line 23 on the top cover 2. By folding the top cover 2 and cutting it along the shearing line 23, the top opening of the cylinder 1 is exposed. This allows the stirring tool to be inserted into the containing space through the exposed top opening of the cylinder 1 and the liquid material in the containing space to be fully stirred. This improves the problem of uneven unloading of liquid material caused by a large amount of sedimentation in the three-dimensional liquid bag 100.

[0045] In this embodiment, by providing a filling component 4 on the top cover 2, during unloading, a stirring tool can be inserted into the containing space through the filling port on the filling component 4 to fully stir and mix the liquid material in the three-dimensional liquid bag 100. This can improve the problem of uneven unloading of liquid material caused by a large degree of sedimentation in the three-dimensional liquid bag 100, while also avoiding the need to disassemble the three-dimensional liquid bag 100.

[0046] Furthermore, by providing a top cover 2 and a bottom cover 3 at the top and bottom of the cylinder 1, the three-dimensional structural strength of the three-dimensional liquid bag 100 can be enhanced. When the three-dimensional liquid bag 100 in this embodiment is placed in the box, the cylinder 1 can fit against the inner side wall of the box, and the bottom cover 3 can fit against the inner bottom wall of the box. This can enhance the fit between the three-dimensional liquid bag 100 and the inner wall of the box, thereby increasing the utilization rate of the three-dimensional liquid bag 100 to the internal volume of the box and reducing the risk of the three-dimensional liquid bag 100 shaking violently and breaking during transportation.

[0047] In some embodiments, the cylinder 1 may be in the shape of a polygonal prism, and the polygonal cylinder 1 includes a plurality of side plates 11 connected end to end, with the side plates 11 located between adjacent edges.

[0048] The top cover 2 may include multiple top segments, each corresponding to the top edge of a plurality of side plates 11. The top segments are foldable relative to the side plates 11. The filling component 4 is disposed on one of the top segments. Each top segment has a crease between itself and the top edge of the side plate 11. The top segments are foldable relative to the cylinder 1 along the crease. Multiple top segments folding inward can seal the receiving space together, and multiple top segments folding outward can expose the opening at the top of the receiving space.

[0049] The bottom cover 3 may include multiple bottom segments, each of which is connected to the bottom edge of a plurality of side plates 11. The bottom segments can be folded relative to the side plates 11. Each bottom segment has a crease between itself and the bottom edge of the cylinder 1. The bottom segments can be folded relative to the cylinder 1 along the crease. When multiple bottom segments are folded inward, they can jointly seal the bottom opening of the cylinder 1. When multiple bottom segments are folded outward, they can expose the opening at the bottom of the receiving space.

[0050] For example, in some embodiments, the cylinder 1 may be in the shape of a quadrangular prism, but it is not limited to this. The cylinder 1 in the embodiments of this disclosure may also be in other shapes besides quadrangular prism, such as triangular prism, hexagonal prism, etc. Of course, the cylinder 1 may also be in other shapes besides polygonal prism, such as cylindrical, frustum, etc. The specific shape may be set according to the internal space of the box in which it is placed, so that the three-dimensional liquid bag 100 can fit against the inner wall of the box.

[0051] like Figure 1 As shown, when the cylinder 1 is in the shape of a quadrangular prism, the cylinder 1 may include four side plates 11 connected end to end, but is not limited to this. The cylinder 1 may also be formed by folding a plate-like structure along the four edges of the quadrangular prism to form four side plates 11. The cylinder 1 is formed by connecting the end of the plate-like structure. The specific design can be set according to the actual situation.

[0052] In this embodiment of the disclosure, the side plate 11 can be a membrane material. For example... Figure 2As shown, when the quadrangular prism-shaped cylinder 1 has four side plates 11, the ends of adjacent side plates 11 can be heat-sealed to form edge welds, thereby achieving the connection between multiple side plates 11. When the cylinder 1 is folded from a plate-like structure to form four side plates 11, the ends of the side plates 11 can be heat-sealed to form the cylinder 1. However, this is not a limitation; the side plates 11 in this embodiment can also be made of materials other than film material, and the connection between the ends of the side plates 11 can also be achieved by means other than heat sealing.

[0053] In some embodiments, when the cylinder 1 is in the shape of a quadrangular prism, the top cover 2 may include four top segments, which are connected one-to-one with four side plates 11. The four top segments can be folded relative to the side plates 11 to seal or expose the top opening of the cylinder 1. The filling component 4 may be disposed on one of the top segments, and the filling port of the filling component 4 penetrates through the top segment to communicate with the receiving space.

[0054] For example, such as Figure 3 and Figure 4 As shown, the top section in this embodiment may include a top cover plate 21 in the shape of an isosceles triangle. The bottom edge of the top cover plate 21 is connected to the top edge of the cylinder 1, and the top cover plate 21 can be folded relative to the cylinder 1 along its bottom edge. The adjacent edges of two adjacent top cover plates 21 are fitted together, that is, the isosceles sides of two adjacent top cover plates 21 are fitted together, so that the top opening of the cylinder 1 can be sealed through the top cover plate 21. The filling component 4 is disposed on one of the top cover plates 21.

[0055] However, it is not limited to this. The top cover plate 21 can also be other shapes besides isosceles triangle, such as isosceles trapezoid or other irregular shapes. In this case, the adjacent sides of the two adjacent top cover plates 21 fit together to achieve a seal on the top opening of the cylinder 1.

[0056] like Figures 5 to 7 As shown, the top section may include top folding plates 22 arranged on both sides of the top cover plate 21. A crease exists between the top folding plate 22 and the top cover plate 21, and the crease between the top folding plate 22 and the top cover plate 21 coincides with the adjacent edge between two adjacent top cover plates 21. When the top cover 2 seals the top opening of the cylinder 1, the top folding plates 22 are symmetrically folded to fit against the top cover plate 21, and the top folding plates 22 are spaced apart from the filling port. By providing the top folding plates 22, this embodiment of the present disclosure can strengthen the structural strength of the top cover 2, thereby reducing the risk of damage to the top cover 2.

[0057] Furthermore, the top folding plate 22 may include a top folding edge and a top fitting edge. The top folding edge is connected to the top cover plate 21, and the remaining edges of the top folding plate 22 are top fitting edges. The top fitting edges of the two top folding plates 22 on the adjacent edges of two adjacent top cover plates 21 are fused together to form a top sealing channel.

[0058] When the top folding plate 22 is symmetrically folded and attached to the top cover plate 21, the orthographic projection of the top folding plate 22 in the accommodating space is located within the orthographic projection of the top cover plate 21 in the accommodating space. That is, the top folding plate 22 can be attached to the top cover plate 21 as a whole, thereby reducing the overall space occupied by the three-dimensional liquid bag 100.

[0059] It should be noted that after the top folding plate 22 is symmetrically folded and attached to the top cover plate 21, the eight top folding plates 22 in the top cover 2 can be evenly arranged on the four top cover plates 21.

[0060] For example, such as Figure 7 As shown, the eight top folding plates 22 in the top cover 2 can be symmetrically arranged about the four top cover plates 21. However, this is not the only possibility; in this embodiment, the top folding plates 22 can be folded towards any adjacent top cover plate 21 as needed.

[0061] The top section and the corresponding side plate 11 in this embodiment can be formed by folding a plate-like structure.

[0062] Specifically, such as Figure 3 and Figure 5 As shown, four plate-like structures can be provided and connected end to end to form a quadrangular prism. The plate-like structures can then be folded along the creases between the side plate 11 and the top cover plate 21, and between the top cover plate 21 and the top folding plate 22, to form a three-dimensional liquid bag 100.

[0063] However, it is not limited to this. The four side plates 11 and the four top pieces in this embodiment can also be folded by a plate-like structure along the crease between the side plate 11 and the top cover plate 21, and the crease between the top cover plate 21 and the top folding plate 22, thereby reducing the connection process between multiple side plates 11 and improving the manufacturing efficiency of the three-dimensional liquid bag 100.

[0064] like Figure 8 As shown, in some embodiments, the shear line 23 may be located on the side of the top segment away from the corresponding side plate 11, and the shear line 23 is parallel to the top edge of the corresponding side plate 11. After folding the top cover 2 outward, the top cover 2 can be cut along the shear line 23 to fully expose the top opening of the cylinder 1, thereby facilitating the placement of the stirring tool in the containing space and the thorough stirring of the liquid material in the containing space.

[0065] In some embodiments, the cross-section of the quadrangular prism-shaped cylinder 1 can be square. In this case, the top edge of the cylinder 1 is square. The top cover 2 can include four top cover plates 21 in the shape of isosceles right triangles. The four top cover plates 21 are the same size. The top folding plates 22 connected to the sides of each top cover plate 21 can be isosceles right triangles of equal size, and the base of the top folding plate 22 is connected to the side of the top cover plate 21. When the top folding plate 22 is folded inward symmetrically, the top folding plate 22 can fit against the top cover plate 21. When the top folding plate 22 is folded outward, the top cover plate 21 and the two top folding plates 22 connected to it can form a rectangle.

[0066] In this embodiment, the cylinder 1 is configured as a square prism with a square cross-section. The four side plates 11 of the cylinder 1 and the top part connected to the side plates 11 have the same structure, which simplifies the manufacturing process of the cylinder 1 and improves manufacturing efficiency.

[0067] However, it is not limited to this. In the embodiments of this disclosure, the cross-section of the quadrangular prism-shaped cylinder 1 can also be rectangular, depending on the actual situation.

[0068] In some embodiments, when the cylinder 1 is in the shape of a quadrangular prism, the bottom cover 3 may include four bottom pieces, which are connected one-to-one with four side plates 11. The four bottom pieces can be folded relative to the side plates 11 to seal or expose the bottom opening of the cylinder 1.

[0069] For example, such as Figure 9 and Figure 10 As shown, the bottom section in this embodiment may include a bottom cover plate 31 in the shape of an isosceles triangle. The bottom edge of the bottom cover plate 31 is connected to the bottom edge of the cylinder 1, and the bottom cover plate 31 can be folded relative to the cylinder 1 along its bottom edge. The adjacent edges of two adjacent bottom cover plates 31 are fitted together, that is, the isosceles sides of two adjacent bottom cover plates 31 are fitted together, so that the bottom opening of the cylinder 1 can be sealed through the bottom cover plate 31.

[0070] However, it is not limited to this. The bottom cover plate 31 can also be other shapes besides isosceles triangle, such as isosceles trapezoid or other irregular shapes. In this case, the adjacent sides of the two adjacent bottom cover plates 31 fit together to achieve a seal on the bottom opening of the cylinder 1.

[0071] like Figures 11 to 13As shown, the bottom section may include bottom folding plates 32 arranged on both sides of the bottom cover plate 31. A crease exists between the bottom folding plates 32 and the bottom cover plate 31, and the crease between the bottom folding plates 32 and the bottom cover plate 31 coincides with the adjacent edge between two adjacent bottom cover plates 31. When the bottom cover 3 seals the bottom opening of the cylinder 1, the bottom folding plates 32 fold symmetrically to fit against the bottom cover plate 31. By providing the bottom folding plates 32, this embodiment of the present disclosure can strengthen the structural strength of the bottom cover 3, thereby reducing the risk of damage to the bottom cover 3.

[0072] Furthermore, the bottom folding plate 32 may include a bottom folding edge and a bottom fitting edge. The bottom folding edge is connected to the bottom cover plate 31, and the remaining edges of the bottom folding plate 32 are bottom fitting edges. The bottom fitting edges of the two bottom folding plates 32 on the adjacent edges of two adjacent bottom cover plates 31 are fused together to form a bottom sealing channel.

[0073] The adjacent edges between two adjacent bottom cover plates 31 can be fused together to prevent the space between the fused bottom fold plates 32 from being connected to the receiving space. This can improve the problem of instability of the bottom cover 3 and waste of liquid material caused by liquid material in the receiving space entering the space between the fused bottom fold plates 32.

[0074] For example, the adjacent edges between two adjacent bottom cover plates 31 can be connected by heat sealing, but it is not limited to this. Other methods besides heat sealing can also be used to connect the adjacent edges between two adjacent bottom cover plates 31.

[0075] When the bottom folding plate 32 is symmetrically folded and attached to the bottom cover plate 31, the orthographic projection of the bottom folding plate 32 in the accommodating space is located within the orthographic projection of the bottom cover plate 31 in the accommodating space. That is, the bottom folding plate 32 can be attached to the bottom cover plate 31 as a whole, thereby reducing the overall space occupied by the three-dimensional liquid bag 100.

[0076] It should be noted that after the bottom folding plate 32 is symmetrically folded and attached to the bottom cover plate 31, the eight bottom folding plates 32 in the bottom cover 3 can be evenly arranged on the four bottom cover plates 31.

[0077] For example, such as Figure 13 As shown, the eight bottom folding plates 32 in the bottom cover 3 can be symmetrically arranged about the four bottom cover plates 31. However, it is not limited to this. In this embodiment of the present disclosure, the bottom folding plates 32 can be folded towards any adjacent bottom cover plate 31 as needed.

[0078] The bottom section and the corresponding side plate 11 in this embodiment can be formed by folding a plate-like structure.

[0079] Specifically, four plate-like structures can be provided and connected end to end to form a quadrangular prism. The plate-like structures can then be folded along the creases between the side plate 11 and the bottom cover plate 31, and between the bottom cover plate 31 and the bottom fold plate 32, to form a three-dimensional liquid bag 100.

[0080] However, it is not limited to this. The four side plates 11 and the four bottom pieces in this embodiment can also be folded by a plate-like structure along the crease between the side plate 11 and the bottom cover plate 31, and the crease between the bottom cover plate 31 and the bottom folding plate 32, thereby reducing the connection process between multiple side plates 11 and improving the manufacturing efficiency of the three-dimensional liquid bag 100.

[0081] When folding along the crease between the bottom cover plate 31 and the bottom fold plate 32, the adjacent folded edges of the two adjacent bottom cover plates 31 can be connected to each other to improve the flow of liquid material in the containment space to the interior of the two connected bottom fold plates 32.

[0082] In some embodiments, the cross-section of the quadrangular prism-shaped cylinder 1 can be square. In this case, the base of the cylinder 1 is square. The bottom cover 3 can include four bottom cover plates 31 in the shape of isosceles right triangles. The four bottom cover plates 31 are the same size. The bottom folding plates 32 connected to the sides of each bottom cover plate 31 can be isosceles right triangles of equal size, and the base of the bottom folding plate 32 is connected to the side of the bottom cover plate 31. When the bottom folding plate 32 is folded inward symmetrically, the bottom folding plate 32 can fit against the bottom cover plate 31. When the bottom folding plate 32 is folded outward, the bottom cover plate 31 and the two bottom folding plates 32 can form a rectangle.

[0083] The present invention discloses a cylindrical body 1 with a square cross-section and four side plates 11 and bottom segments connected to the side plates 11 having the same structure, thereby simplifying the manufacturing process of the cylindrical body 1 and improving manufacturing efficiency.

[0084] However, it is not limited to this. In the embodiments of this disclosure, the cross-section of the quadrangular prism-shaped cylinder 1 can also be rectangular, depending on the actual situation.

[0085] In some embodiments, the filling component 4 may include: a base 41, a filling connector 42, and a sealing cap 43. For example... Figure 14As shown, the base 41 is mounted on the top cover 2, and a filling port is provided on the base 41. The filling connector 42 is hollow inside and open at both ends. The filling connector 42 is located outside the receiving space, and its bottom surface is connected to the top surface of the base 41. The bottom opening of the filling connector 42 communicates with the filling port to obtain liquid material from the receiving space through the filling port. A threaded groove is provided on the inner side of the filling connector 42. The outer periphery of the sealing cap 43 is threaded to facilitate threaded connection with the inner side of the filling connector 42 and to seal the filling port, thereby improving the problem of external impurities entering the receiving space and causing liquid material contamination. By separating the sealing cap 43 from the filling connector 42, a stirring tool can be inserted into the filling connector 42 and then into the receiving space through the filling port to achieve thorough stirring of the liquid material.

[0086] For example, the base bottom 41 can be a hollow cylinder with openings at both ends. The base bottom 41 can be heat-sealed onto the top cover 2, so that the filling port on the base bottom 41 is opposite to the opening on the top cover 2, thereby allowing the filling port to communicate with the receiving space.

[0087] This disclosure also provides a packaging structure that may include a box and any of the three-dimensional liquid bags 100 described above. The box is hollow inside and open at the top. The three-dimensional liquid bag 100 is placed inside the box, and when the three-dimensional liquid bag 100 is filled with liquid material, the outer surface of the three-dimensional liquid bag 100 is in contact with the inner wall of the box.

[0088] Specifically, when the three-dimensional liquid bag 100 is placed inside the box, the bottom cover 3 can be completely fitted with the inner bottom wall of the box, and the cylinder 1 can be completely fitted with the inner side wall of the box.

[0089] Before the three-dimensional liquid bag 100 is filled with liquid material, the top and / or bottom sections of the three-dimensional liquid bag 100 can be folded outwards, and the three-dimensional liquid bag 100 can be arranged according to... Figure 15 The folding method reduces the space occupied by the three-dimensional liquid bag 100.

[0090] When unloading from the three-dimensional liquid bag 100, if the liquid material needs to be thoroughly stirred, the sealing cover 43 can be opened to insert a stirring tool into the containing space for stirring. Alternatively, the top cover 2 can be cut along the shear line 23 and folded outwards to fully expose the top opening. In this case, the liquid material can be stirred while unloading.

[0091] In this embodiment, the three-dimensional liquid bag 100 has a high degree of adhesion to the inner wall of the box after being loaded with liquid material. The three-dimensional liquid bag 100 has a high effective utilization rate of the internal volume of the box. When unloading, the three-dimensional liquid bag 100 can be exposed through the filling part 4 or the shear line 23 to expose the top opening of the cylinder 1, so that the stirring tool can be inserted into the containing space to achieve stirring and unloading at the same time. This makes the stirring of liquid material more convenient and thorough, the unloading more convenient, and reduces the residue of liquid material in the three-dimensional liquid bag 100.

[0092] The three-dimensional liquid bag 100 in this embodiment can be used in industries such as liquid chemicals, fruit juices, and jams. The box can be a foldable turnover box, and the volume of the box can be greater than or equal to 1000L, but is not limited to this. The volume of the box can also be less than 1000L, and can be set according to the actual situation.
