Description

Technical Field

[0001] The embodiments of the present invention relate to the field of transportation and storage, and in particular to a foldable container. Background Art

[0002] A turnover container, which mainly consists of a lid, a side frame, and a base. In order to be able to recycle the container, hinges are generally provided on the side frames, which can be folded up by the hinges, and the side frames and the base are generally clamped together. To ensure the safety of the goods during transportation, it is usually necessary to use strapping tape to tighten the side frames and the base to prevent the components from being separated from the installation position during transportation, thereby causing damage to the goods. Since the length and width of this type of container are generally more than 1m, the strapping tape is not convenient for one person to operate alone, and it is a disposable consumable material, which increases the cost of use. Therefore, a novel and reliable structure is needed that can firmly connect the base and the side frame, replacing the strapping tape and being easy to operate. Summary of the Invention

[0067] Unless the context requires otherwise, throughout the specification and claims, the word "comprise" and variations such as "include" and "have" should be construed in an open, inclusive sense, that is, should be interpreted to mean "including, but not limited to."

[0068] The following will describe in detail various embodiments of the present invention in conjunction with the accompanying drawings to provide a clearer understanding of the objectives, features and advantages of the present invention. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0069] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any manner in one or more embodiments.

[0070] As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. It should be noted that the term "or" is generally employed in its sense including "and / or" unless the context clearly dictates otherwise.

[0071] In the following description, in order to clearly show the structure and working mode of the present invention, many directional words will be used for description, but words such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and should not be understood as restrictive terms.

[0072] The following describes a collapsible container according to an embodiment of the present invention with reference to the accompanying drawings. Figure 1 and Figure 2As shown, the foldable container 3 includes a base 31, a side frame 33, a first hook 4, and a first elastic band 5. The side frame 33 is disposed on the base 31 and is engaged with the base 31. The first hook 4 is disposed on either the base 31 or the side frame 33, while the first elastic band 5 is disposed on the other of the base 31 and the side frame 33, and the first elastic band 5 is operably hooked on the first hook 4.

[0073] Since the first hook 4 and the first elastic band 5 are respectively provided on the side frame 33 and the base 31, the first hook 4 is provided on either the side frame 33 or the base 31, and the first elastic band 5 is provided on the other of the side frame 33 and the base 31. During use of the foldable container 3, the first elastic band 5 can be hung on the first hook 4, so that the side frame 33 and the base 31 can be relatively fixed together, avoiding the need to use a packing tape to fix the side frame 33 and the base 31 together, thereby improving the convenience of use of the foldable container 3.

[0074] Specifically, such as Figure 1 and Figure 2 As described above, there are multiple first hooks 4 and first elastic bands 5, each of which is arranged around the axis of the foldable container 3. Each first hook 4 corresponds to at least one first elastic band 5, and each first elastic band 5 can be hooked onto its corresponding first hook 4. In this embodiment, each first hook 4 corresponds to one first elastic band 5, but it should be noted that in some embodiments, two, three, or more first elastic bands 5 may correspond to one first hook 4.

[0075] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the side frame 33 and the base 31 are both rectangular frames, and the first hook 4 and the first elastic band 5 are both arranged at the top corners of the side frame 33 and the base 31 respectively, that is, when the first hook 4 is arranged on the side frame 33, the first hook 4 is located at the top corner of the side frame 33, and the first elastic band 5 is located at the top corner of the base 31; when the first hook 4 is arranged on the base 31, the first hook 4 is located at the top corner of the base 31, and the first elastic band 5 is located at the top corner of the side frame 33.

[0076] In this embodiment, the first hook 4 is arranged on the side frame 33, and the first hook 4 can slide on the side frame 33 along the height direction of the foldable container 3. At the same time, the foldable container 3 also includes a fixing member 10, which can be operated to fix the first hook 4 on the side frame 33 after the first hook 4 slides to a preset position.

[0077] like Figure 4As described above, in this embodiment, the side frame 33 includes: a plurality of side panels 331 and a first hinge 1 , and the side panels 331 are operably connected along the circumferential direction of the foldable container 3 through the first hinges 1 to form the side frame 33 .

[0078] Specifically, such as Figure 5 and Figures 7 to 9 As shown, the first hinge 1 includes a first connecting member 11, a second connecting member 12, and a first flexible member 13. The first connecting member 11 and the second connecting member 12 are both arranged along the height direction of the foldable container and abut each other. The first connecting member 11 and the second connecting member 12 are made of a rigid material. The first connecting member 11 and the second connecting member 12 are both connected to the first flexible member 13. The first connecting member 11 and the second connecting member 12 can rotate relative to each other around the height direction of the foldable container through the first flexible member 13.

[0079] Compared with the prior art, the embodiment of the present invention has a first hinge 1 including a first connecting member 11 , a second connecting member 12 and a first flexible member 13 . The first flexible member 13 enables the first connecting member 11 and the second connecting member 12 to rotate relative to each other.

[0080] At the same time, the first connecting member 11 and the second connecting member 12 both extend in the height direction of the foldable container, and the first connecting member 11 and the second connecting member 12 also abut against each other. At the same time, the materials of the first connecting member 11 and the second connecting member 12 are both rigid materials. Therefore, when the first hinge is installed on the foldable container, the height direction of the foldable container is the height direction of the foldable container. Since the first connecting member 11 and the second connecting member 12 are both made of rigid materials, the first connecting member 11 and the second connecting member 12 form two columns, which is equivalent to adding two reinforcing ribs along the height direction of the foldable container. Therefore, it can effectively improve the load-bearing capacity of the foldable container and further expand the use scenarios of the foldable container.

[0081] Specifically, such as Figure 5 and Figures 7 to 9 As shown, the first connecting member 11 includes: a first connecting portion 111 and a first abutting portion 112 arranged along a direction perpendicular to the height of the foldable container. The second connecting member 12 includes: a second connecting portion 121 and a second abutting portion 122 arranged along a direction perpendicular to the height of the foldable container. As shown in the figure, the radial inner sides of the first connecting portion 111 and the second connecting portion 121 are respectively connected to the first flexible member 13, and the first abutting portion 112 and the second abutting portion 122 are operably abutted against each other. As shown in the figure, the first connecting portion 111, the first abutting portion 112, the second connecting portion 121 and the second abutting portion 122 all extend in the height direction of the foldable container, together forming two columns.

[0082] like Figure 5 and Figures 7 to 9 As shown, the first flexible member 13 is a flexible strip that extends along the height direction of the foldable container, and the two ends of the flexible strip in the width direction are respectively connected to the first connecting portion 111 and the second connecting portion 122. Since the first flexible member 13 is provided, the first flexible member 13 is located radially inward of the first connecting portion 111 and the second connecting portion 121, so that the first connecting member 11 and the second connecting member 12 can be bent through the first flexible member 13, and due to the flexibility of the first flexible member 13, the rebound force will be very small after the first connecting member 11 and the second connecting member 12 are folded relative to each other. Moreover, the bending resistance of the flexible portion can extend the service life of the first hinge. The material of the first flexible member 13 can be TPU, TPE, POE, silicone, soft PVC and other materials.

[0083] like Figure 9 As shown, the first abutting portion 112 and the second abutting portion 122 are both bent portions. When the first hinge is in the first state, the first connecting portion 111 and the second connecting portion 121 are perpendicular to each other, and the first abutting portion 112 and the second abutting portion 122 abut against each other. Figures 16 to 19 As shown, when the first hinge 1 is in the second state, the first connecting portion 111 and the second connecting portion 121 overlap each other, and the first abutting portion 112 and the second abutting portion 122 are separated from each other. Figures 16 to 19 As shown, when the first hinge is in the first state (i.e., when the first hinge is open), the first hinge 1 is in the shape of an L. Of course, in some embodiments, the first connecting portion 111 and the second connecting portion 121 may not be perpendicular to each other, but may be at an obtuse angle or an acute angle.

[0084] like Figure 5 As shown, the first hook 4 is arranged on the first hinge 1, and either the first abutting portion 112 or the fourth abutting portion 222 has a hollow portion 6, which extends along the height direction of the foldable container 3. Part of the first hook 4 is stuck in the hollow portion 6, and the other part is exposed outside the hollow portion 6 and connected to the first elastic band 5.

[0085] like Figure 5 and Figure 9 As shown, the hollow portion 6 is open toward the radially outer side of the foldable container, and the portion of the first hook 4 engaged in the hollow portion 6 is operable to slide in the hollow portion 6 along the height direction of the foldable container 3. In this embodiment, both the first abutting portion 112 and the fourth abutting portion 222 have a hollow portion 6, and the first hook 4 is partially engaged in either hollow portion 6. Therefore, in actual practice, the first hook 4 can be selectively engaged with the first abutting portion 112 or the fourth abutting portion 222 as needed.

[0086] In addition, in order to form the hollow portion 6 on the first abutting portion 112 or the fourth abutting portion 222, as shown in FIG. Figure 5 and Figure 9 As shown, the first abutting portion 112 and the second abutting portion 122 each include an inner plate 141, an outer plate 142, and a support plate 143. The inner plate 141 and the outer plate 142 are arranged relative to each other in the radial direction of the first hinge 1, with the inner plate 141 located radially inward and the outer plate 142 located radially outward. The support plate 143 is arranged between the inner plate 141 and the outer plate 142 and is connected to the inner plate 141 and the outer plate 142, respectively. The support plate 143 can strengthen the strength between the inner plate 141 and the outer plate 142, thereby improving the supporting force of the first hinge 1. As shown in the figure, the area surrounded by the inner plate 141, the outer plate 142, and the support plate 143 is the hollow portion. A notch is provided in the outer plate 142, so that the hollow portion 6 is open to the outside of the foldable container, and a portion of the first hook 4 is inserted into the hollow portion 6 through the notch.

[0087] In addition, if Figure 5 and Figure 9 As shown, the outer plate 142 is a curved plate that protrudes away from the inner plate 141. The outer plate 142 in the first abutting portion 112 and the outer plate 142 in the second abutting portion 122 abut against each other. The mutual abutment of the two outer plates 142 allows the first abutting portion 112 and the second abutting portion 122 to support each other, preventing the first flexible member 13 from bearing the height force from the foldable container. At the same time, the abutment of the two outer plates 142 acts as a limiter, preventing the first hinge 1 from further outward rotation, thereby maintaining the position and state of the first hinge 1 stable.

[0088] In addition, if Figure 5 and Figure 9 As shown, the first connecting portion 111 defines a first engaging groove 1111 on a side away from the first abutting portion 112, and the first engaging groove 1111 extends through the first connecting portion 111 along the height direction of the foldable container. The second connecting portion 121 defines a second engaging groove 1211 on a side away from the second abutting portion 122, and the second engaging groove 1211 extends through the second connecting portion 121 along the height direction of the foldable container.

[0089] In addition, if Figure 4 As shown, the first hinge 1 is located at the four corners of the foldable housing. When the first hinge 1 is opened, it is 90 degrees. The side edges of each side plate 331 are respectively inserted into the first clamping groove 1111 and the second clamping groove 1211 of the first hinge 1. Figure 5 and Figure 9 As shown, the first hinge 1 further includes a welding rib 15 located in the first snap-fit ​​groove 1111 and / or the second snap-fit ​​groove 1211, and the welding rib 15 extends along the height direction of the foldable container. The two adjacent side panels are respectively snapped into the first snap-fit ​​groove and the second snap-fit ​​groove of the first hinge 1. Specifically, as shown in FIG. Figure 5 and Figure 9As shown, in this embodiment, the first snap-fitting groove 1111 and the second snap-fitting groove 1211 of the first hinge 1 are both provided with welding ribs 15, and the material of the welding ribs 15 is plastic. Before the side panel 331 is inserted into the first snap-fitting groove 1111 and the second snap-fitting groove 1211, the welding ribs 15 can be heated to melt the welding ribs 15, and then the side panel 331 can be inserted. After the welding ribs 15 cool down, the welding ribs 15 are connected to the side panel 331, thereby fixing the side panel 331 in the first snap-fitting groove 1111 or the second snap-fitting groove 1211.

[0090] In addition, if Figure 4 As shown, one pair of side panels 331 in the two pairs of side panels 331, and each of the side panels 331 in the pair of side panels 331 includes: a first plate body 3311 and a second plate body 3312 arranged opposite to each other in a height direction perpendicular to the foldable container 3, the first plate body 3311 and the second plate body 3312 are connected by the second hinge 2, and the first plate body 3311 and the second plate body 3312 can be operated to flip relative to each other into the foldable container 3 through the second hinge 2.

[0091] Specifically, such as Figure 4 、 Figure 6 and Figures 10 and 11 As shown, the second hinge 2 has a substantially identical structure to the first hinge 1. Specifically, the second hinge 2 also includes a third connecting portion 211 and a third abutting portion 212 connected thereto, as well as a fourth connecting portion 221 and a fourth abutting portion 222 connected thereto. The second hinge also includes a second flexible member 23, wherein the third abutting portion 212 and the fourth abutting portion 222 abut against each other. The second flexible member 23 is connected radially outwardly of the third and fourth connecting portions, respectively. The second hinge 2 also extends along the height direction of the foldable container 3, and thus also constitutes a column. As shown in the figure, the main difference between the second hinge 2 and the first hinge 1 is that the structures of the third supporting portion 212 and the fourth supporting portion 222 are different, and the relative positions of the third connecting portion 211 and the fourth connecting portion 221 are different, but the structures of the third connecting portion 211 and the fourth connecting portion 221 are basically the same, and the third connecting portion 211 and the fourth connecting portion 221 also have a first snap-fit ​​groove 1111, a second snap-fit ​​groove 1211 and a welding rib 15. Therefore, the structural description of the second hinge 2 can refer to the description of the first hinge 1. As for the difference between the second hinge 2 and the first hinge 1, it is described as follows.

[0092] In this embodiment, if Figures 16 to 19 As shown, when the second hinge 2 is in the first position (ie, the second hinge 2 is in the open position), the first connecting member 21 and the second connecting member 22 are in the same straight line, and the third abutting portion 212 and the fourth abutting portion 222 abut against each other. Figures 16 to 19As shown, when the second hinge 2 is in the second position, the third connecting portion 211 and the fourth connecting portion 221 are arranged in parallel, and the third abutting portion 212 and the fourth abutting portion 222 are separated from each other. Figures 16 to 19 As shown, in this embodiment, when the second hinge 2 is opened, the third connecting portion 211 , the third abutting portion 212 , the fourth abutting portion 222 and the fourth connecting portion 221 are all on the same straight line.

[0093] In addition, if Figure 4 、 Figure 6 and Figures 10 and 11 As shown, the fourth supporting portion 222 is provided with a groove 241 on the side away from the fourth connecting portion 221, and the third supporting portion 212 is a limit block; when the second hinge 2 is in the first position, the limit block is located in the groove 241 and is radially opposed to the groove 241 by the second hinge 2; when the second hinge is in the second position, the limit block is located outside the groove 241.

[0094] Of course, in this embodiment, Figure 4 、 Figure 6 and Figures 10 and 11 As shown, a weight-reducing groove 243 can be opened on the side of the limit block away from the third connecting portion 211. The weight-reducing groove 243 can reduce the weight of the limit block, and the weight-reducing groove 243 enables the limit block to be elastically deformed, making it easier for the limit block to be inserted into the groove 241.

[0095] like Figure 4 、 Figure 6 and Figures 10 and 11 As shown, the second hinge 2 is the same as the first hinge 1, and the first snap-fit ​​groove 1111 and the second snap-fit ​​groove 1211 of the second hinge 2 are both provided with welding ribs 15. As shown in the figure, the opposite sides of the first plate 3311 and the second plate 3312 are respectively inserted into the first snap-fit ​​groove 1111 and the second snap-fit ​​groove 1211 of the second hinge 2, and the first plate 3311 and the second plate 3312 can be fixed in the first snap-fit ​​groove 1111 and the second snap-fit ​​groove 1211 by heating the welding ribs 15.

[0096] like Figures 1 to 3 As shown, the foldable container 3 further includes: a top cover 32, a second hook 7, and a second elastic band 8. The top cover 32 and the base 31 are arranged relative to each other and can cover the side frame 33. The second hook 7 is arranged on either the top cover 32 or the side frame 33, and the second elastic band 8 is arranged on the other of the side frame 33 and the top cover 32. During use of the foldable container 3, the second elastic band 8 can be hung on the second hook 7, so that the side frame 33 and the top cover 32 can be relatively fixed together, avoiding the need to use a packing tape to fix the side frame 33 and the top cover 32 together, thereby improving the convenience of use of the foldable container 3.

[0097] Specifically, such as Figures 1 to 3 As described above, there are multiple second hooks 7 and second elastic bands 8, and each second hook 7 and each second elastic band 8 is arranged around the axis of the foldable container 3. Each second hook 7 corresponds to at least one second elastic band 8, and each second elastic band 8 can be hooked onto its corresponding second hook 7. In this embodiment, each second hook 7 corresponds to one second elastic band 8, but it should be noted that in some embodiments, two, three, or more second elastic bands 8 may correspond to one second hook 7.

[0098] Specifically, such as Figures 1 to 3 As shown, in this embodiment, the side frame 33 and the top cover 32 are both rectangular frames, and the second hook 7 and the second elastic band 8 are both arranged at the top corners of the side frame 33 and the top cover 32 respectively, that is, when the second hook 7 is arranged on the side frame 33, the second hook 7 is located at the top corner of the side frame 33, and the second elastic band 8 is located at the top corner of the top cover 32; when the second hook 7 is arranged on the top cover 32, the second hook 7 is located at the top corner of the top cover 32, and the second elastic band 8 is located at the top corner of the side frame 33.

[0099] In this embodiment, the second hook 7 is disposed on the side frame 33 and is capable of sliding along the height of the foldable container 3 on the side frame 33. The foldable container 3 also includes a fixing member 10, which is operable to fix the second hook 7 to the side frame 33 after the second hook 7 slides to a predetermined position. In practice, the first hook 4 and the second hook 7 can be slid to appropriate positions along the length of the first hinge 1 based on the lengths of the first elastic band 5 and the second elastic band 8, and then secured with the fixing member 10. This method facilitates adjustment of the preload force of the foldable container 3 after it is connected and locked.

[0100] Preferably, Figure 5 As shown, the second hook 7 is partially engaged in the hollow portion 6 of the third abutting portion 212112 or the fourth abutting portion 222122 and slides along the height direction of the hollow portion 6. The second elastic band 8 is provided on the top cover 32 and is operably hooked to the second hook 7. Specifically, in this embodiment, the structure of the second hook 7 is the same as that of the first hook 4 and has the same connection relationship with the first hinge 1, the difference being that the first hook 4 is located at the bottom, while the second hook 7 is located at the top.

[0101] like Figure 12As shown, the first hook 4 includes a first sliding portion 41, a first hook portion 42, and a first intermediate portion 43. The first sliding portion 41 is engaged within the hollow portion 6 and can slide within the hollow portion 6 along the extension direction of the hollow portion 6. The first hook portion 42 is disposed outside the hollow portion 6 and opposite to the first sliding portion 41. The first intermediate portion 43 is connected to the first sliding portion 41 and the first hook portion 42 respectively. The first hook portion 42 extends upward from the first intermediate portion 43 and toward the first sliding portion 41. Since the first hook portion 42 also extends toward the first sliding portion 41, it is more convenient to hang the first elastic band 5 on the first hook portion 42.

[0102] Similarly, if Figure 13 As shown, the first hook 4 and the second hook 7 each include a second sliding portion 71, a second hook portion 72, and a second intermediate portion 73. The second sliding portion 71 is retained within the hollow portion 6 and is operable to slide within the hollow portion 6 along the extension direction of the hollow portion 6. The second hook portion 72 is disposed outside the hollow portion 6 and opposite the second sliding portion 71. The second intermediate portion 73 is connected to the second sliding portion 71 and the second hook portion 72, respectively. The second hook portion 72 extends upward from the second intermediate portion 73 and toward the second sliding portion 71. Since the second hook portion 72 also extends toward the second sliding portion 71, it is more convenient to hook the second elastic band 8 on the second hook portion 72. Of course, in some embodiments, the first hook 4 and the second hook 7 can also have other shapes, such as a single hook, or the first sliding portion 41 and the first hook portion 42 are parallel to each other, and the second sliding portion 71 and the second hook portion 72 are parallel to each other, as long as it does not depart from the scope of the present invention.

[0103] Specifically, in this embodiment, Figure 8 As shown, the first connecting member 11 and the second connecting member 12 are made of plastic, and the fixing member 10 is a self-tapping screw. When the first hook 4 or the second hook 7 slides to the preset position, the self-tapping screw penetrates the connecting plate and is inserted into the first connecting portion 111 or the second connecting portion 121. Of course, in some embodiments, the first connecting member 11 and the second connecting member 12 can also be made of metal products, such as stainless steel or iron. In this case, the fixing member 10 can be a screw. A plurality of threaded holes are preset on the first connecting member 11 or the second connecting member 12. Each threaded hole is arranged along the height direction of the first connecting member 11 or the second connecting member 12. As needed, the first hook 4 or the second hook 7 can be set between any two adjacent threaded holes, and then the first hook 4 or the second hook 7 can be fixed by using two screws in conjunction with the two threaded holes.

[0104] In addition, if Figure 14As shown, the first elastic band 5 has a plurality of first hook portions 51, each of which is operably connected to the first hook 4; wherein the first hook portions 51 are spaced apart from each other along the length direction of the first elastic band 5. Figure 19 As shown, the second elastic band 8 has a plurality of second hook portions 81, each of which is operably coupled to the second hook 7; the second hook portions 81 are spaced apart along the length of the second elastic band 8. Specifically, the first hook portion 51 and the second hook portion 81 are through holes formed in the first elastic band 5 and the second elastic band 8.

[0105] Specifically, such as Figures 1 to 3 As shown, the base 31 and the top cover 32 are both provided with a card hole 9, the first connecting end 52 of the first elastic band 5 is carded in the card hole 9 on the base 31, and the second connecting end 82 of the second elastic band 8 is carded in the card hole 9 on the top cover 32, as shown in FIG. Figures 1 to 3 As shown, the first connecting end 52 of the first elastic band 5 and the second connecting end 82 of the second elastic band 8 are both ends without a through hole.

[0106] In addition, in order to make the top cover 32 and the base 31 snap together with the side frame 33, as shown in FIG. Figures 20 to 22 As shown, the top cover 32 is provided with an upper slot 321 on the side facing the base 31, and the upper end of each side panel 331 is operably located in the upper slot; and\or, the base 31 is provided with a lower slot 311 on the side facing the top cover 32, and the lower end of each side panel 331 is operably located in the lower slot 311.

[0107] In this embodiment, an upper slot 321 is provided on the top cover 32, a lower slot is provided on the base 31, and both ends of the first hinge 1 and the second hinge 2 in the length direction are also located in the upper slot 321 and the lower slot 311. In this way, the supporting force of the foldable container 3 can be maximized.

[0108] Since the top cover 32 has an upper slot 321 and the base 31 has a lower slot 311 , the side panels 331 will not bend, deform, or shift inward when the container is impacted by an external force, thereby more safely protecting the goods inside the container and more firmly supporting the upper goods.

[0109] In addition, if Figure 1As shown, the base 31 includes a bottom plate 312 and at least three support columns 313. The base 31 is operably engaged with each side plate 331. The lower engaging slot 311 is located on the bottom plate 312, and each support column 313 is located on the side of the bottom plate 312 facing away from the top cover. Each hinge is positioned opposite a support column 313 along the height of the foldable container 3. In this embodiment, there are eight support columns 313 arranged in an array on the base 31, with each hinge corresponding to a support column 313. This ensures that each hinge is supported by a support column 313, thereby enhancing the support strength of the foldable container 3.

[0110] like Figures 16 to 19 and Figure 23 As shown, when the foldable container 3 needs to be folded, the top cover can be removed, the side frame 33 can be removed from the base 31, and the first plate 3311 and the second plate 3312 on both sides can be pushed to rotate into the container. Since the second flexible member 23 of the second hinge 2 is arranged away from the container, and the first flexible member 13 of the first hinge 1 is arranged toward the container, the outer surfaces of the first plate 3311 and the second plate 3312 are overlapped through the second hinge 2, and the outer surfaces of the side plates 331 are overlapped through the first hinge 1, as shown in FIG. Figures 16 to 19 As shown, the side frames 33 are finally folded together.

[0111] During this process, due to the flexible characteristics of the first flexible part 13 and the second flexible part 23, after the side frame 33 is folded, the shape of each side panel 331 will not rebound, and the side panels 331 will fit tightly together, reducing the thickness of each side panel 331 after folding. At the same time, there is no need to use packaging tape to bundle the folded side frame 33 to prevent the side panels 331 from rebounding, thereby improving the ease of use of the foldable container 3.

[0112] When the foldable container needs to be opened, the side frames are opened and inserted into the lower slots, and then the first elastic bands are hung on the corresponding first hooks. When the top cover is closed on the side frames, the upper ends of the side frames are located in the upper slots, and then the second elastic bands are hung on the corresponding second hooks.

[0113] The foldable container of the present invention can tightly connect the top cover, side frame and base together, and is easy to operate. It can provide a certain degree of pre-tightening force during connection, so that the connection between the various components of the box body is tighter, ensuring the transportation safety of the goods.

[0114] While preferred embodiments of the present invention have been described in detail above, it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide further embodiments.
