[0039] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, each embodiment of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will appreciate that in each embodiment of the present invention, many technical details are provided to help readers better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can still be implemented.

[0040] In the following description, for the purpose of illustrating the various disclosed embodiments, certain specific details are set forth in order to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the relevant art will recognize that the embodiments may be practiced without one or more of these specific details. In other cases, well-known devices, structures, and techniques associated with this application may not be shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0041] 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."

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] The following describes embodiments of the present invention with reference to the accompanying drawings. Figure 1 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, the foldable logistics box 100 includes: an outer box 1 and an inner liner 2 detachably disposed within the outer box 1, the inner liner 2 having an upwardly opening 20. The outer box 1 has a base 11, a lid 12 for sealing the accommodating opening 20 of the inner liner 2, a pair of opposing first side panels 13 and a pair of opposing second side panels 14 foldably connected to the base 11, with adjacent first and second side panels 13, 14 connected and surrounding the base 11, and the top of the inner liner 2 is snap-fitted to each of the first and second side panels 13, 14.

[0047] From the above, it is not difficult to find that since the inner liner 2 and the outer box 1 are detachably connected, and the box cover 12 is hinged to a first side panel 13 and can be flipped and folded to the outer surface of the first side panel 13, when the first side panel 13 and the second side panel 14 are folded onto the base 11, the box cover 12 is also folded onto the base 11, thereby realizing the folding of the outer box 1, saving space, and reducing transportation costs. By snapping the top of the inner liner 2 with the first side panel 13 and the second side panel 14, the inner liner 2 can be positioned in the outer box 1 and is not easily separated from the outer box 1. When the logistics box is flipped to unload the material, the inner liner 2 will not fall out. Moreover, the inner liner 2 is positioned, and when the box cover 12 covers the inner liner 2, it will not leak due to the deformation of the inner liner 2 due to the pressure of the cover, so that the inner liner 2 is doubly protected.

[0048] Further, such as Figure 1 、 Figure 2 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, the inner liner 2 comprises a bottom 22, a pair of opposing first sidewalls 21 surrounding the bottom 22, and a pair of opposing second sidewalls 27. The pair of first sidewalls 21 are disposed opposite and engaged with the pair of first side panels 13, respectively, while the pair of second sidewalls 27 are disposed opposite and engaged with the pair of second side panels 14, respectively. This ensures that the sidewalls of the inner liner 2 are evenly stressed, providing better support. It is understood that in other embodiments, the inner liner 2 may also be cylindrical or have other shapes.

[0049] like Figure 1 、 Figure 2 and Figure 10 As shown, a second side wall 27 of the inner liner 2 has a recessed area 23 that is recessed toward the inner liner 2. The drain port 24 is located within the recessed area 23, so that the drain port 24 does not protrude from the side wall 21 of the inner liner 2, making it easier to place the inner liner 2 into the outer box 1 and allowing the inner liner 2 to be nested. A valve is provided at the drain port 24, which can be opened or closed by the valve. The second side wall 27 with the recessed area 23 is a vertical wall, while the remaining side walls are inclined walls that converge toward the bottom 22 of the inner liner 2. In other words, the drain port 24 is provided on the vertical wall, making it easier to contact the drain port 24 when using it during operation. The remaining inclined walls also allow multiple inner liner 2 to be nested after being removed from the outer box 1. In other embodiments, all four side walls can also be inclined walls that converge toward the bottom 22 of the inner liner 2. The inner diameter of the top of the inner liner 2 is larger than the outer diameter of the bottom of the inner liner 2.

[0050] Further, such as Figure 1As shown, each first side panel 13 is a long side panel, each second side panel 14 is a short side panel, and a flap 5 is disposed on one of the second side panels 14. The flap 5 is connected to the base 11 via a latch 7. The flap 5 can be used to block the drain port 24. When the flap 5 is opened, the drain port 24 can be directly accessed. In other embodiments, the inner container 2 has a drain port 24, and at least one of the first side panels 13 and the second side panels 14 is provided with a flap, with the drain port 24 facing and opposite the flap.

[0051] Specifically, if Figure 2 、 Figure 9 、、 Figure 10 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, each first side panel 13 has a first retaining strip 134 protruding toward the interior of the outer box 1, and the outer surface of the first bladder side wall 21 has a first limiting portion 25 placed on the first retaining strip 134. It is understood that in other embodiments, the first retaining strip 134 can be provided on the first bladder side wall 21, while the first limiting portion 25 is provided on the first side panel 13.

[0052] In addition, if Figure 2 、 Figure 9 、、 Figure 10 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, the upper edge of the first sidewall 21 faces outward from the inner liner 2 and bends downward to form a first stopper 25. This avoids forming the first stopper 25 directly on the surface of the first sidewall 21, thereby increasing the strength of the inner liner 2. This also creates a larger surface area at the top of the inner liner 2 for the lid 12 to abut against and seal the inner liner 2. It is understood that in other embodiments, the first stopper 25 can also be a protruding ridge, with a snap-in position formed on the ridge for the first retaining strip 134 to engage.

[0053] Further, such as Figure 2 、 Figure 9 、、 Figure 10 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15As shown, the first limiting portion 25 has protruding portions 250 extending downwardly at both ends along its length. The length of the first limiting portion 25 is the same as the length of the first liner sidewall 21. The first clamping strip 134 is operably positioned between the two protruding portions 250. The area of ​​the first limiting portion 25 between the two protruding portions 250 supports the first clamping strip 134. The two protruding portions 250 limit the first clamping strip 134, preventing the inner liner 2 from moving along the length of the first liner sidewall 21 and also providing support for the inner liner 2. In other embodiments, the first limiting portion 25 may also be formed with a groove for the first clamping strip 134 to fit into.

[0054] In addition, if Figure 2 、 Figure 9 、、 Figure 10 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, each second side panel 14 has a second retaining strip 143 protruding into the outer box 1, and the outer surface of the second liner side wall 27 has a long groove 270 that is positioned on the second retaining strip 143. This prevents the inner liner 2 from shaking up and down, and prevents the inner liner 2 from detaching from the foldable logistics box 100 when the foldable logistics box 100 is flipped. In other embodiments, the second retaining strip 143 can be formed on the second liner side wall 27, and the second side panel 14 has a long groove, and the second retaining strip 143 can be embedded in the long groove 270.

[0055] In addition, if Figure 2 、 Figure 9 、 Figure 10 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, the upper edge of the second sidewall 27 faces the outside of the inner liner 2 and bends downward to form an outer edge 26, and a long groove 270 is formed on the outer edge 26. The outer edge 26 makes the second sidewall 27 more secure, eliminating the need to form the long groove 270 on the wall surface of the second sidewall 27. Moreover, the top of the inner liner 2 has more area to contact the box cover 12, allowing the box cover 12 to better seal the inner liner 2.

[0056] Further, such as Figure 2 、 Figure 9 、、 Figure 10 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15As shown, each second side panel 14 comprises, from top to bottom, an upper panel 141 and a lower panel 142. The lower edge of the upper panel 141 is hingedly connected to the upper edge of the lower panel 142 via a second hinge 140. The upper panel 141 is connected to the adjacent first side panel 13 via a latch 6. The upper panel 141 is operable to tilt relative to the base 11 toward the outside or toward the inside of the outer box 1. The second side panel 14 is hingedly connected to the upright post on the base 11 via a hinge axis 4. When the outer box 1 is folded, the latch 6 is released, allowing the second side panel 14 to rotate toward the base 11. When the second side panel 14 is to be erected, it rotates about the hinge axis 4, securing the position. A second retaining bar 143 is provided on the upper panel 141. When the upper panel 141 is tilted about the second hinge 140 toward the inside of the outer box 1 to a vertical position, the second retaining bar 143 engages with the elongated slot 270. The second hinge 140 may be a metal hinge.

[0057] Specifically, if Figure 2 、 Figure 9 、 Figure 10 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, when removing the inner liner 2 from the outer box 1, the two upper plates 141 are flipped outwards toward the outer box 1 around the second hinge 140, the second clip 143 leaves the long slot 270, and the first clip 134 is supported on the first limiting portion 25. The inner liner 2 can be lifted upwards and removed from the outer box 1. When installing the inner liner 2 into the outer box 1, the two upper plates 141 are flipped outwards toward the outer box 1 around the second hinge 140, and the inner liner 2 is inserted into the outer box. The first limiting portion 25 corresponds to the first clip 134, and the first limiting portion 25 is supported above the first clip 134. The two upper plates 141 are then flipped into the outer box 1 to a vertical position, and the second clip 143 is snapped into the long slot 270 to position the inner liner 2.

[0058] In this embodiment, the outer edge 26 and the first limiting portion 25 are an integral piece, and are integrally formed with the first gallbladder side wall 21 and the second gallbladder side wall 27 .

[0059] Further, such as Figure 2 、 Figure 9 、、 Figure 10 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, the box cover 12 is hinged to the top of a first side panel 13 through a first hinge 3. The box cover 12 can be operatively flipped to the outer surface of the first side panel 13 to which it is hinged and arranged opposite to the outer surface of the first side panel 13. Figure 3As shown, the first hinge 3 has a hinge body 31, a first hinge pin 32, and a second hinge pin 33. The first hinge pin 32 connects the hinge body 31 and the box cover 12, and the second hinge pin 33 connects the hinge body 31 and the top of a first side panel 13. In other embodiments, the first hinge 3 can also be directly covered on the inner container without being hinged to the first side panel, and the box cover is then locked with the outer box by a lock. In other embodiments, such as Figure 16 As shown, the box cover 500 is detachably connected to the first and second side panels of the outer box 1. When in use, the box cover 5 covers the top of the first and second side panels to seal the inner container, and the box cover 5 is fastened to the outer box 1 on all sides by locks. When not in use, the box cover 5 is removable and separated from the first and second side panels to become an independent unit. The structure of the box cover 500 is also basically the same as that of the box cover 5. When this type of container is folded, the folding structure of the first and second side panels of the outer box 1 is the same as the folding structure of the first and second side panels of the present embodiment. After the side panels are folded onto the base, the box cover 500 can be placed on top of the first and second side panels.

[0060] Further, further, such as Figure 1 、 3 As shown, the base 11 has a bottom plate 111 and two pairs of opposite columns 112 and 113 respectively connected to the four corner ends of the bottom plate 111. The columns can be metal columns. The bottom plate 111 is rectangular, and the four columns are respectively at the four corner ends of the rectangle. Each second side panel 14 and each first side panel 13 are respectively clamped between two different columns and hinged with two adjacent columns. As shown in the figure, a first side panel 13 is clamped between a column 112 and a column 113, and a second side panel 14 is clamped between two columns 112. The structures of the columns 112 and 113 are the same. The following is a specific description taking a column 112 as an example. Figure 3 、 Figure 4 and Figure 5As shown, the column has a column body and a support foot 10 with a groove. The column body is vertically connected to the support foot 10, and the first side panel 13 and the second side panel 14 are both hingedly connected to the column body. A slot 114 opening upward is provided at the top of the column 112, and a protrusion 131 is provided on the side prism 130 of the first side panel 13 to be operably engaged with the slot 114. A slide 115 extending from top to bottom is provided on the column, and the side prism 130 of the first side panel 13 is operably slidable along the slide 115. The slot 114 is provided at the top of the wall of the slide 115 and has an upward opening. A long groove 116 extending from top to bottom is provided on the wall of the slide 115, and an insert 133 is provided on the side prism 132 of the first side panel 13 to be operably slidable along the long groove 116. When the first side panel 13 is upright, the insert 133 is stuck in the bottom of the long slot 116, and the protrusion 131 is embedded in the slot 114. When the first side panel 13 needs to be folded, the lock bolt 6 that locks the first and second side panels 13 and 14 is pulled open. The first side panel 13 is first raised, and the insert 133 slides upward in the long slot, the protrusion 131 disengages the slot 114, and then the first side panel 13 is bent into the outer box 1, finally achieving the folding of the first side panel 13. Each second side panel 14 is hinged to the corresponding column via a hinge shaft 4. The second side panel 14 rotates around the axis of the hinge shaft 4 and folds toward the base 11. The lower ends of the columns 112 and 113 have hinge holes, which are closer to the bottom panel 111 than the long slot 116. The hinge shaft is connected to the hinge hole. When folding the outer box 1 , the two second side panels 14 are folded first, and then the two first side panels 13 are folded, so that the second side panels 14 are located below the first side panels 13 .

[0061] In addition, if Figure 5 As shown, the folded first side panel 13 and the second side panel 14 are separated from the pillars to form a spacing area 70, leaving a placement area for the pillars of other outer boxes 1. As shown in the figure, the column 112 has a first vertical plate 1121 and a second vertical plate 1122 forming an angle with the first vertical plate 1121. The bottoms of the first vertical plate 1121 and the second vertical plate 1122 are inserted into the supporting legs 10. A groove is provided at the bottom of the supporting legs 10. The edges where the first vertical plate 1121 and the second vertical plate 1122 are connected together form the side edges of the column. A sliding groove is formed between the first vertical plate 1121 and the second vertical plate 1122. The sides of the first vertical plate 1121 and the second vertical plate 1122 facing away from each other have inclined surfaces, and the two inclined surfaces gradually move away from the side edges from top to bottom, so that the top size of the first vertical plate 1121 and the second vertical plate 1122 is smaller and away from the first side plate 13 and the second side plate 14, and can be inserted into the supporting legs 10 of other outer boxes 1, and also provide space for placing the supporting legs 10 of other outer boxes 1.

[0062] In addition, if Figure 8As shown, when the outer box 1 is not folded, two outer boxes 1 can be stacked. The outer diameter of the top of the side prism 130 of the first side panel 13 is smaller than the inner diameter of the groove, and the side prism 130 of the first side panel 13 can be inserted into the groove. In other words, when the two outer boxes 1 are stacked, the side prism 130 of the first side panel 13 is inserted into the groove at the bottom of the support leg 10. It is understood that in other embodiments, the top of the side prism of the first side panel 13 can also be provided with a recessed opening, and when stacked, the support leg is inserted into the recessed opening.

[0063] Further, such as Figure 9 As shown, the box lid 12 comprises an outer frame 121 and a cover 122 connected to the outer frame 121. The cover 122 is used to seal the receiving opening 20 of the inner liner 2. The cover 122 has a filling port 120 that allows access to the inner liner 2. The filling port 120 has a cover. The filling port 120 can be a bottle mouth structure, and the cover is screwed onto the filling port 120 via threads. Of course, other structures are also possible. The cover 122 is used to seal the receiving opening 20 of the inner liner 2. The first side panel 13 is hingedly connected to the cover 122 via the first hinge 3.

[0064] In addition, if Figure 1 As shown, the outer frame 121 is a mesh frame and covers the outer surface of the cover body 122. The filling port 120 on the cover body 122 is arranged opposite to the mesh holes of the mesh frame.

[0065] Specifically, if Figure 2 、 Figure 9 As shown, the cover 122 has a protruding abutting boss 1221 on the side facing away from the outer frame 121. The abutting boss 1221 is circumferentially arranged and abuts against the top surface of the inner liner 2. The accommodating opening 20 of the inner liner 2 is a rectangular opening formed by the top surface of the inner liner 2. The abutting boss 1221 abuts against the top surface of the inner liner 2 to seal the accommodating opening 20. In other embodiments, the accommodating opening 20 can also have other shapes, and the abutting boss 1221 matches the top surface of the inner liner 2.

[0066] Further, such as Figure 9As shown, a sealing member 1222 is provided on the abutting boss 1221. The sealing member 1222 is used to be clamped between the abutting boss 1221 and the top surface of the inner liner 2 when the abutting boss 1221 abuts against the top surface of the inner liner 2. The sealing member 1222 can be a rubber pad or other sealing sheet. The sealing member 1222 can be adhered to the abutting boss 1221, or a protrusion can be provided on the sealing member 1222 to snap into the abutting boss 1221.
