Description

Technical Field

[0001] This utility model relates to the field of logistics, and in particular to a foldable container. Background Technology

[0002] Existing reusable containers generally consist of a container body and a lid. In actual use, after goods are manufactured and processed, they are loaded into the reusable container, and after filling, the lid is closed. The container is then transported to the customer or destination, where unloading is performed using a discharge device at the bottom of the container or by using external equipment to lift and tilt the container. To facilitate discharge, existing reusable containers typically have a discharge port at the bottom for opening and releasing goods. However, goods can easily remain in the corners of the container, making discharge difficult. Utility Model Content

[0003] The purpose of this invention is to provide a foldable container that facilitates the discharge of goods and reduces the space occupied inside the container.

[0004] To address the aforementioned technical problems, embodiments of this utility model provide a foldable container, comprising:

[0006] A guide discharge component is disposed within the receiving space. The guide discharge component has a frame circumferentially arranged along the inner wall of the housing, and a plurality of plates hinged to the frame. The guide discharge component is operably raised and lowered along the height direction of the housing. When the guide discharge component is located in a first preset position, the plates are operably inclined and extended toward the discharge port, and the plurality of plates surround the frame to form a discharge space that docks with the discharge port. When the guide discharge component is located in a second preset position, the plurality of plates are folded onto the base.

[0007] Compared to existing technologies, this invention allows for the raising and lowering of the guide discharge component. When the guide discharge component is positioned at a first preset position, the plate is tilted, allowing goods to enter the discharge space and slide down through the plate to the discharge outlet. Since the plate is hinged to the frame, a drive device lowers the guide discharge component to a second preset position. With the guide discharge component lowered, the plate rotates around the frame, folding onto the base. This reduces the size of the guide discharge component, minimizing its space requirements. Furthermore, the two pairs of side plates fold onto the base, maintaining a relatively small folded height, reducing operator difficulty and lowering transportation and storage costs.

[0059] The embodiments of this utility model are described below with reference to the accompanying drawings.

[0060] The first embodiment of this utility model relates to a foldable container. For example... Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the foldable container includes: a housing 1, a guide discharge component 2, and a drive device. The housing 1 includes: a base 11 with a discharge port, two pairs of opposing side plates 12, and a gate for opening or closing the discharge port. The two pairs of side plates 12 form a receiving space 14 around the base 11, and the side plates 12 are connected to the base 11 and configured to be operably unfolded or folded relative to the base 11. The guide discharge component 2 is disposed within the receiving space 14, and the guide discharge component 2 has a frame 21 circumferentially arranged along the inner wall of the housing 1, and multiple plates 22 hinged to the frame 21. The drive device is used to raise and lower the guide discharge component 2; wherein, when the guide discharge component 2 is in a first preset position, the guide discharge component 2 forms a funnel shape, realizing its guiding discharge function, and the plates 22 operably extend at an inclined angle towards the discharge port, with the multiple plates 22 forming a discharge space 23 around the frame 21 that connects with the discharge port; when the guide discharge component 2 is in a second preset position, the multiple plates 22 are folded onto the base 11. Specifically, the container 1 has two pairs of opposing sidewalls 15. When the guide discharge component 2 is in the first preset position, the guide discharge component 2 has a funnel-shaped structure, with the plate 22 inclined. The distance between the top of the plate 22 and the sidewall 15 of the container 1 is less than the distance between the bottom of the plate 22 and the sidewall 15 of the container 1. That is, the cross-sectional area of ​​the discharge space 23 gradually increases from the top to the bottom, and the plate 22 can abut against the bottom plate 111 of the base 11. At the same time, each plate 22 abuts against its adjacent plate 22, so that the goods can be stably discharged from the discharge space 23 to the discharge port along the guide plate 22. In other embodiments, gaps between adjacent plates 22 are also feasible. In this embodiment, when the guide discharge component 2 is in the first preset position, the angle α between the bottom end of the plate 22 and the horizontal plane where the base 11 is located is greater than or equal to 25°. Other angles are also possible in actual use. The gate can be configured as a horizontal push-pull mechanism on the base plate 111 of the base 11 to open or close the discharge port, and the gate is also equipped with a handle for easy operation. The drive device allows the frame 21 to slide downward along the side wall 15 of the box 1, allowing the plates 22 to gradually rotate around the frame 21 until they fold onto the base 11. At this time, each plate 22 can be tilted and laid on the base 11 as shown in the figure, reducing the volume of the guide discharge component 2 and releasing the accommodating space 14, which can hold more goods.

[0061] To facilitate the discharge of goods, a funnel is usually prefabricated at the bottom of the container used for packaging and transportation. Before filling semi-finished or prefabricated goods, the funnel is placed on the base 11 inside the box 1. When the semi-finished or prefabricated goods inside the box need to be further processed and discharged from the box, the discharge device at the bottom of the box 1 is opened to discharge the goods. At the same time, the prefabricated or semi-finished goods far from the center of the discharge port are guided along the side wall of the funnel to move towards the center of the funnel discharge port, and finally all the goods in the box are discharged and emptied. Because the pre-fabricated funnel sidewall inside the box needs to maintain a predetermined angle with the plane of the base 11 to guide the goods to the central discharge port, the funnel requires a fixed height. Therefore, when the funnel is placed in the folding container and the goods inside are emptied, the funnel must be removed before the folding container can be folded. In cases where the container is relatively large, the funnel fits closely to the container sidewall, making funnel removal complex and laborious. If the funnel is not removed, its fixed height will occupy space, increasing the height of the folded container and thus increasing the transportation or storage space required for the packaging carrier, ultimately increasing the cost of empty container returns and warehousing costs. In this embodiment, the foldable container uses a drive device to raise and lower the guide discharge component 2. When the guide discharge component 2 is in a first preset position, the plate 22 is tilted, allowing the goods to enter the discharge space 23 and slide down through the plate 22 to the discharge port for discharge. Since the plate 22 is hinged to the frame 21, the guide discharge component 2 is driven to descend by the drive device, allowing the guide discharge component 2 to slide down to the second preset position. As the height of the guide discharge component 2 decreases, the plate 22 rotates around the frame 21 and folds onto the base 11. At this time, the volume of the guide discharge component 2 can be reduced, reducing the occupation of the storage space 14. There is no need to remove the guide discharge component 2 to release the storage space 14. Moreover, the two pairs of side plates 12 are folded onto the base 11, so that the box 1 still maintains a small folding height after folding, reducing the difficulty of operation for operators and reducing transportation and storage costs.

[0062] In this embodiment, one pair of side plates 12 are long side plates and one pair are short side plates. The long side plates include a lower plate 122 that is hinged to the base 11, and an upper plate 121 that is hinged to the lower plate 122. The upper plate 121 and the lower plate 122 are folded together and operably folded above the frame 21 to press the frame 21. The short side plates can be in the same manner.

[0063] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the frame 21 has two pairs of frame edges 214 that are respectively opposite to the two pairs of side plates 12. Each frame edge 214 is connected to a plate 22, and the frame edge 214 can be operably slidable along the side wall surface 15 of the box 1. That is, the shape of the frame 21 matches the box 1. In this embodiment, the cross-section of the box 1 is rectangular, and the frame 21 is also rectangular. The frame 21 has four frame plates, and four plates 22 are also provided correspondingly.

[0064] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the top surface of frame 21 is an inclined surface extending towards the discharge port. Frame 21 has an extension plate 211 extending towards the base 11, which operably abuts against the side wall surface 15. This prevents goods from accumulating on the top surface of frame 21 and allows them to slide into the discharge space 23 through the top surface of frame 21. Furthermore, the abutment between the extension plate 211 and the side wall surface 15 minimizes gaps that could trap goods, reducing the risk of goods residue. The plate 22 is connected to frame 21 by a pin. Both frame 21 and plate 22 have limiting parts to secure the pin, ensuring a stable connection between the plate 22 and frame 21.

[0065] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the drive device includes a support assembly 331 and a drive component 32. The support assembly 331 supports the guide discharge component 2, and the drive component 32 drives the support assembly 331 to move the guide discharge component 2 up and down.

[0066] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the support assembly 331 includes a pair of brackets, bracket 311 and bracket 312, which are cross-connected and hinged together. The intersection of brackets 311 and bracket 312 forms a rotating shaft. Both ends of one bracket 312 are slidably connected to the guide discharge member 2 and rotatably connected to the base 11, respectively. Both ends of the other bracket 311 are rotatably connected to the guide discharge member 2 and slidably connected to the base 11, respectively. A driving member 32 is connected to at least one bracket 312 and drives the bracket 312. In this embodiment, one end of one bracket 312 is provided with a first roller 313 that slides along the bottom edge of the frame 21, and one end of the other bracket 311 is also provided with a second roller 314 that slides along the base 11. The first roller 313 and the second roller 314 are on the same vertical line. When the driving device drives the bracket 312, the included angle and height of the two brackets change, and the ends of the two brackets slide closer or further apart in the horizontal direction via the rollers. A pair of support components 331 are provided and are arranged opposite each other on both sides of the guide discharge member 2. The two support components 331 on both sides are connected by a linkage 33. The linkage 33 can be fixedly connected between the two second rollers 314, so that when the support of one side of the support component 331 moves, the support of the other side of the support component 331 moves synchronously. In other embodiments, a slider can be connected to the support, and tracks are provided on both the frame 21 and the base 11 so that when the included angle and height of the two supports change, one end of the support can slide. It is understood that the ability to raise or lower the guide discharge member 2 by realizing the two cross-arranged supports, and the corresponding adjustment of the connection relationship between the two supports and the base 11 and the frame 21, are all within the scope of protection of this utility model.

[0067] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the driving component 32 is hinged to the brackets 311 and 312 and is located between the brackets 311, 312 and the plate 22. One end of the bracket 312 is slidably connected to the guide discharge component 2 and is slidably disposed along the frame 21. The driving end of the driving component 32 drives one bracket 312, and the other end of the driving component 32 is hinged to the linkage component 33 to achieve hinge connection with another bracket 311. When the driving component 32 drives the bracket 312, the included angle and height of the two brackets change, which in turn changes the height of the guide discharge component 2. For example, when the height of the guide discharge component 2 decreases, the height of the two brackets also decreases. The end of the driving component 32 connected to the bracket can rotate, so that the driving component 32 can be stably placed when the guide discharge component 2 moves up and down. When the guide discharge component 2 is in the second position and the plate 22 is folded, the included angle between the driving component 32 and the brackets 311 and 312 changes, but the driving component 32 still has reasonable placement space.

[0068] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the drive component 32 includes an air pump 321. A slot 16 is provided on the housing 1 for connecting an air passage 322 that interfaces with the air pump 321. The air nozzle 323 of the air passage 322 is inserted into the slot 16. Understandably, in other embodiments, the drive component 32 may not be an air pump 321 but rather a cylinder or other power component.

[0069] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the base 11 has a base plate 111 and two pairs of opposing flanges 112 extending upward from the base plate 111. The two pairs of flanges 112 correspond to two pairs of side plates 12, and the side plates 12 are hinged to their corresponding flanges 112. The slots 16 can be formed on the flanges 112 or on the side plates 12. In addition, the height of the folded guide discharge component 2 is basically no higher than the height of the flanges 112. The side plates 12 are then folded over the guide discharge component 2, and the total height of the folded guide discharge component 2 and the side plates 12 is also basically no higher than the height of the flanges 112. Finally, the cover plate 4 of the foldable container 100 is placed on top of the base 11, so that the overall folded height of the container 1 remains small, reducing the difficulty of operation for operators and reducing transportation and storage costs.

[0070] Furthermore, such as Figure 3 , Figure 4 As shown, when the guide discharge component 2 is in the second preset position, multiple plates 22 sequentially surround to form a bottom opening 20 that connects with the discharge port.

[0071] Specifically, such as Figure 1 , Figure 2 As shown, when the guide discharge component 2 is fixed in the first preset position, the four plates 22 abut against each other and support each other. Simultaneously, two plates 22 are supported by the base plate 111 of the base 11, and the other two plates 22 are supported by the gate. The plates 22 are tilted. In other embodiments, all plates 22 can be supported by the base plate 111. When discharge is required, the gate is pulled to open the discharge port. Because multiple plates 22 abut against each other and are supported by the base plate 111, the plates 22 can maintain an tilted state to allow goods to be discharged. When the guide discharge component 2 needs to be moved, the support can be pulled by the drive component 32, increasing the angle between the supports and reducing their vertical height. This lowers the overall height of the guide discharge component 2 and reduces the angle between the plate 22 and the frame 21, allowing multiple plates 22 to fold onto the base 11. As shown in the figure, the folded plate 22's discharge space 23 is reduced to almost nothing. Multiple plates 22 fold onto the base 11, and the multiple plates 22 sequentially surround each other to form a bottom opening 20 opposite to the discharge port. Figure 3 , Figure 4 As shown, goods are stored in the container 1 in the initial state. The guide discharge component 2 can be located in the second preset position. When goods need to be discharged, the gate is opened and the bottom opening 20 is connected to the discharge port. After the goods in the container 1 are partially emptied, the remaining tail material will pull the guide discharge component 2 to the first preset position through the drive component 32. The guide discharge component 2 forms a funnel shape to assist in the discharge and emptying of the tail material. When storing the foldable container 100, the guide discharge component 2 is unlocked and slid down to the second preset position, and then the container 1 is folded.

[0072] Understandably, in this embodiment, the drive device is located inside the container to drive the guide discharge component. However, in other embodiments, there may be no drive device; instead, an external component is inserted into the container from the outside to support the frame. The guide discharge component is then lowered by manually removing or lowering the external component. For example, if the guide discharge component is initially in the second position and needs to be raised, an external component can be inserted into the container to raise the frame and lift the guide discharge component. This can be done manually using tools such as jacks and support frames, or by using power equipment such as cylinders or support frames to support the guide discharge component. When the guide discharge component needs to be lowered, the same external component can be used, or the external component can be removed to lower the guide discharge component. The external component can be located on both sides or more sides of the container to stably drive the guide discharge component. Of course, it is also acceptable to have an external component on one side to stably drive the guide discharge component.

[0073] Specifically, such as Figure 5 , Figure 6 As shown, the drive device 7 is installed outside the housing 1. The drive device 7 includes a support frame 72 inserted into the housing 1 to carry the frame 21 for lifting. The support frame 72 can be manually operated to raise the guide discharge component 2, or it can be driven by a pneumatic or electric power device.

[0074] by Figure 7 , Figure 8 , Figure 9 , Figure 10 For example, the drive device 7 further includes a drive component 71 connected to the support frame 72. A long cavity 114 extending along the height direction of the housing 1 is provided on the side wall of the housing 1, and the drive component 71 drives the support frame 72 to move along the long cavity 114. The drive component 71 includes an air pump, which drives the support frame 72. The platform 70 can support the base, allowing the base 11 to have a first certain height, thus allowing the support frame 72 sufficient travel. Drive devices 7 can be provided on both sides of the housing 1, and these drive devices 7 can be disassembled or replaced with other types according to usage requirements. In other embodiments, such as... Figure 10 , Figure 11 , Figure 12As shown, a gate may also be omitted. When the guide discharge component is in the second preset position, the multiple plates fold onto the base to cover the discharge port. When material needs to be discharged, the guide discharge component can be driven to rise via a drive device. During the rising process, the multiple plates gradually rise and surround each other to form a bottom opening. Part of the goods can be discharged first, and after the partial discharge, the guide discharge component can be raised again, and the bottom opening can gradually increase in size; or the guide discharge component can be directly raised to the first preset position, at which point the bottom opening is at its maximum for discharging goods. The choice can be made according to the actual situation.

[0075] The second embodiment of this utility model relates to a foldable container 200. The second embodiment is largely the same as the first embodiment, with the main difference being that the support component 51 and the driving component 52 in the driving device 5 are not the same. In the second embodiment, as shown... Figure 14 , Figure 15 , Figure 16 , Figure 17 As shown, the support assembly 51 includes a pair of brackets 511 and 512 arranged vertically opposite each other, and the brackets 511 and 512 are hinged together. The bracket 511 is hinged to the guide discharge member 2, and the bracket 512 is hinged to the base 11. The driving member 52 is used to drive the opposite ends of the brackets 511 and 512 to move closer or further away in the horizontal direction.

[0076] In this embodiment, as Figure 14 , Figure 15 , Figure 16 , Figure 17 As shown, when the guide discharge component 2 is in the first preset position, the angle α between the bottom end of the plate 22 and the horizontal plane of the base 11 is greater than or equal to 25°. Other angles are also acceptable in actual use. The gate can be configured as a horizontal push-pull type set on the bottom plate 111 of the base 11 to open or close the discharge port, and the gate is also equipped with a handle for easy operation. The drive device 5 causes the frame 21 to slide down along the side wall 15 of the box 1, allowing the plate 22 to gradually rotate around the frame 21 until it folds onto the base 11. At this time, each plate 22 can be tilted and laid on the base 11 as shown in the figure, reducing the volume of the guide discharge component 2 and releasing the accommodating space 14, which can hold more goods.

[0077] Specifically, such as Figure 14 , Figure 15 , Figure 16 , Figure 17As shown, bracket 511 is an upper bracket including upper branch 5111 and upper branch 5112, which are hinged to guide discharge component 2. An upper support seat 215 for connecting upper branch 5111 and upper branch 5112 is also provided on frame 21. Bracket 512 is a lower bracket including lower branch 5121 and lower branch 5122, which are hinged to base 11. A lower support seat 113 for connecting lower branch 5121 and lower branch 5122 is also provided on base 11. Upper branch 5111 and lower branch 5121 are arranged opposite each other and hinged together, as are upper branch 5112 and lower branch 5122. Upper branch 5111 and lower branch 5121 are connected to the same connector 513, which has an internal thread and is threaded to a screw. The upper branch 5112 and the lower branch 5122 are connected to the same connector 514, which has an internal thread and is threaded to the screw. The base 11 is also provided with a limiting member 17 to limit the bracket 511 and the bracket 512.

[0078] Furthermore, such as Figure 14 , Figure 15 , Figure 16 , Figure 17 As shown, the driving component 52 includes a screw, and the driving component 52 is threadedly connected to the bracket and the support. The side wall 15 of the housing 1 is provided with an elongated cavity 114 extending along the height direction of the housing 1. The screw extends horizontally, and the end of the screw extends into the elongated cavity 114. The screw can be rotated by an external component, so that the support 511 and the support 512 approach each other horizontally at one end of the screw. At this time, the included angle between the upper branch 5111 and the upper branch 5112 becomes smaller, and the included angle between the lower branch 5121 and the lower branch 5122 becomes smaller. The overall height of the bracket and the support increases, driving the guide discharge component 2 to rise until the first preset position, and the screw moves upward along the elongated cavity 114. The screw is then rotated in the opposite direction, causing the brackets and supports to move away from each other horizontally at one end of the screw. At this time, the included angle between the upper branches 5111 and 5112 increases, and the included angle between the lower branches 5121 and 5122 also increases. The overall height of the brackets 511 and 512 decreases, driving the guide discharge component 2 to lower until it reaches the second preset position. The screw then moves downward along the elongated cavity 114. In this embodiment, the elongated cavity 114 is disposed in the flange 112.

[0079] Understandably, in this embodiment, the drive device is located inside the container to drive the guide discharge component. However, in other embodiments, there may be no drive device; instead, an external component is inserted into the container from the outside to support the frame. The guide discharge component is then lowered by manually removing or lowering the external component. For example, if the guide discharge component is initially in the second position and needs to be raised, an external component can be inserted into the container to raise the frame and lift the guide discharge component. This can be done manually using tools such as jacks and support frames, or by using power equipment such as cylinders or support frames to support the guide discharge component. When the guide discharge component needs to be lowered, the same external component can be used, or the external component can be removed to lower the guide discharge component. The external component can be located on both sides or more sides of the container to stably drive the guide discharge component. Of course, it is also acceptable to have an external component on one side to stably drive the guide discharge component.

[0080] Specifically, such as Figure 18 , Figure 20 As shown, the drive device 8 is installed outside the housing 1. The drive device 8 includes a support frame 82 inserted into the housing 1 to carry the frame 2 for lifting. The support frame 82 can be manually operated to raise the guide discharge component 2, or it can be driven by a pneumatic or electric power device.

[0081] by Figure 19 , Figure 21 For example, the structure of the driving device is roughly the same as that in this embodiment. The driving device 8 also includes a driving component 81 connected to the support frame 82, and the driving component 81 includes a screw 812. The driving device also includes a support assembly. The support frame 82 is connected to the bracket 811 of the support assembly. A long cavity 114 extending along the height direction of the box 1 is provided on the side wall of the box 1. The support frame 82 is driven to move up and down along the long cavity 114 by the cooperation of the bracket 811 and the screw 812 of the support assembly. The specific cooperation structure of the bracket 811 and the screw 812 is the same as the above scheme, and will not be described in detail here. It is understood that the driving component that drives the support assembly and the support frame to move up and down is not limited to a screw, but can also be a cylinder, an air pump or a motor, etc. The driving device can be provided on both sides of the box. The driving device can be disassembled or replaced with other types according to the usage requirements. It is not difficult to find that this embodiment is a system embodiment corresponding to the first embodiment. This embodiment can be implemented in conjunction with the first embodiment. The relevant technical details mentioned in the first embodiment are still valid in this embodiment. In order to reduce repetition, they will not be repeated here. Accordingly, the relevant technical details mentioned in this embodiment can also be applied to the first embodiment.

[0082] The third embodiment of this utility model relates to a foldable container 300. The third embodiment is largely the same as the first embodiment, with the main difference being that the driving device 6 in the first embodiment is different from the driving device 6 in the third embodiment. In the third embodiment, as... Figure 22 , Figure 23 , Figure 24 , Figure 25 , Figure 26 , Figure 27 As shown, the driving device 6 includes a screw 61, which is threadedly connected to the plate 22, and drives the plate 22 to raise or lower the frame 21.

[0083] Furthermore, such as Figure 22 , Figure 23 As shown, the frame 21 has two pairs of frame edges 214 that are respectively opposite to the two pairs of side plates 12. Each frame 21 is connected to a plate 22. Each pair of opposite plates 22 is connected to a screw 61, and the screw 61 penetrates the side wall 15 of the box body 1.

[0084] Specifically, such as Figure 24 , Figure 25 , Figure 26 , Figure 27 As shown, there are two screws 61, one screw 61 connected to one plate 22, and the screw 61 passes through the flange 112 of the base 11, which can be easily driven to rotate the screw 61 from the outside by an external component. The screw 61 extends horizontally and is set close to the bottom plate 111 of the base 11. The bottom of the plate 22 is fixed with a connector 24 with internal threads, and the screw 61 is threadedly connected to the connector 24. When the guide discharge component 2 needs to be moved to the first preset position to perform its guide discharge function, the screw 61 can be rotated to move the ends of the pair of plates 22 connected to the screw 61 in a direction away from each other. The frame 21 is hinged to the top of the plate 22. At this time, the top of the plate 22 can be rotated around the frame 21, and the plate 22 gradually drives the frame 21 to stand upright until the plate 22 forms a suitable tilt angle with the horizontal plane, so that the plate 22 can guide the discharge of goods. When the guide discharge component 2 needs to be folded onto the base 11, the screw 61 can be rotated in the opposite direction, so that the ends of the pair of plates 22 connected to the screw 61 move toward each other. The top of the plate 22 rotates around the frame 21, and the plate 22 gradually tilts down, lowering the height of the frame 21 until it reaches the second preset position, where the plate 22 is folded and laid on the base 11.

[0085] Since the first embodiment corresponds to this embodiment, this embodiment can be implemented in conjunction with the first embodiment. The relevant technical details mentioned in the first embodiment remain valid in this embodiment, and the technical effects achievable in the first embodiment can also be realized in this embodiment. To reduce repetition, they will not be repeated here. Correspondingly, the relevant technical details mentioned in this embodiment can also be applied to the first embodiment. The preferred embodiments of this utility model have been described in detail above, but it should be understood that, if necessary, aspects of the embodiments can be modified to utilize aspects, features, and concepts from various patents, applications, and publications to provide other embodiments.
