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:

[0005] The housing includes: a base with a discharge port and two pairs of opposing side panels; the two pairs of side panels form a receiving space around the base, and the side panels are connected to the base and configured to be operablely unfolded or folded relative to the base;

[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 plurality of plates surround the frame to form a discharge space that connects with the discharge port.

[0007] A locking device is provided for locking the guide discharge component to the side wall of the housing or unlocking the guide discharge component from the side wall of the housing.

[0008] When the locking device fixes the guide discharge member in the first preset position of the housing, the plate can be operably tilted and extended towards the discharge port; after the locking device unlocks the guide discharge member from the side wall, the guide discharge member can be operably slid along the height direction of the housing, and when the guide discharge member slides to the second preset position, multiple plates fold onto the base.

[0009] Compared to existing technologies, this invention's embodiment uses a locking device to fix the guide discharge component to a first preset position. At this position, the plate tilts, 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, the locking device unlocks the guide discharge component from the box, allowing it to slide down to a second preset position. The guide discharge component's height decreases, and the plate, upon contacting the base, 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.

[0072] The embodiments of this utility model are described below with reference to the accompanying drawings.

[0073] The first embodiment of this utility model relates to a foldable container 100. For example... Figure 1 , Figure 2 , Figure 3 As shown, the collapsible container 100 includes: a housing 1, a guide discharge component 2, and a locking device 3. The housing 1 includes: a base 11 with a discharge port 10, two pairs of opposing side panels 12, and a gate 13 for opening or closing the discharge port 10. Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, two pairs of side plates 12 surround the base 11 to form a receiving space 14. The side plates 12 are connected to the base 11 and are configured to be operably unfolded or folded relative to the base 11. A guide discharge member 2 is disposed within the receiving space 14. The guide discharge member 2 has a frame 21 circumferentially arranged along the inner wall of the housing 1, and a plurality of plates 22 hinged to the frame 21. The plurality of plates 22 surround the frame 21 to form a discharge space 23 that abuts against the discharge port 10. A locking device 3 is used to lock the guide discharge member 2 onto the side wall 15 of the housing 1 or to unlock the guide discharge member 2 from the side wall 15 of the housing 1. When the locking device 3 fixes the guide discharge component 2 in the first preset position of the housing 1, the guide discharge component 2 forms a funnel shape, realizing its guiding discharge function. The plate 22 can be operably extended at an angle towards the discharge port 10. After the locking device 3 unlocks the guide discharge component 2 from the side wall surface 15, the guide discharge component 2 can be operably slid along the height direction of the housing 1. When the guide discharge component 2 slides to the second preset position, multiple plates 22 fold onto the base 11, that is, the guide discharge component 2 descends to its lowest position. Specifically, the housing 1 has two pairs of opposing side wall surfaces 15. Figure 9 As shown, when the guide discharge component 2 is in the first preset position, the guide discharge component 2 has a funnel-shaped structure, and the plate 22 is inclined. The distance between the top of the plate 22 and the side wall 15 of the box 1 is less than the distance between the bottom of the plate 22 and the side wall 15 of the box 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, so that the plate 22 can be supported. 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 10 along the guide plate 22. In other embodiments, gaps between adjacent plates 22 are also feasible, as long as the supporting force between the plate 22 and the base 11 is sufficient. In this embodiment, as Figure 4 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 where the base 11 is located is greater than or equal to 25°. Other angles are also acceptable in actual use. For example... Figure 5 As shown, the gate 13 can be configured as a horizontally sliding type mounted on the base plate 111 of the base 11 to open or close the discharge port 10, and the gate 13 is also equipped with a handle 131 for easy operation. Figure 13 , Figure 16 As shown, after the locking device 3 unlocks the guide discharge component 2 from the box body 1, the frame 21 can slide down along the side wall 15 of the box body 1, allowing the plate 22 to be gradually pushed and rotated around the frame 21 by the base 11 until it is folded on the base 11. At this time, each plate 22 can be tilted and laid on the base 11 as shown in the figure, so that the volume of the guide discharge component 2 is reduced, releasing the accommodating space 14, which can hold more goods.

[0074] 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 middle of the discharge port 10 are guided along the side wall of the funnel to move towards the middle of the funnel discharge port 10, 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 in order to guide the goods to the discharge port 10 in the middle, the funnel needs a fixed height. Therefore, when the funnel is placed in the folding container and the goods inside the box are emptied, the funnel needs to be removed before the folding container can be folded. When the container is relatively large, the funnel fits relatively well with the sidewall of the container, making the removal of the funnel more complicated and laborious. If the funnel is not removed, its fixed height will occupy space, causing the height of the container to increase after folding, which in turn increases the transportation or storage space of the packaging carrier, ultimately increasing the cost of empty return of the container and warehousing costs. In this embodiment, the foldable container 100 can fix the guide discharge component 2 to the first preset position through the locking device 3. At this time, the plate 22 is tilted, and the goods can enter the discharge space 23 and slide down through the guide plate 22 to the discharge port 10 for discharge, preventing the goods from remaining in the box 1. Since the plate 22 is hinged to the frame 21, the guide discharge component 2 and the box 1 are unlocked by the locking device 3, allowing the guide discharge component 2 to slide down to the second preset position. The height of the guide discharge component 2 decreases, and the plate 22 rotates around the frame 21 after contacting the base 11, thus folding 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.

[0075] 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.

[0076] Furthermore, such as Figure 7 As shown, the locking device 3 includes at least one pair of locking components 31, which respectively lock or unlock a pair of sidewalls 15 to the frame 21.

[0077] Specifically, such as Figure 9As shown, the frame 21 has two pairs of frame edges that are respectively opposite to the two pairs of side plates 12. Each frame edge is connected to a plate 22, and the frame edges 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.

[0078] Furthermore, such as Figure 10 As shown, the top surface 210 of the frame 21 is an inclined surface extending towards the discharge port 10. The 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 the frame 21 and allows them to slide into the discharge space 23 via the top surface 210 of the 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 the frame 21 by a pin 24. Both the frame 21 and the plate 22 have limiting parts 25 that limit the pin 24, ensuring a stable connection between the plate 22 and the frame 21.

[0079] Furthermore, such as Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 As shown, the locking assembly 31 includes: a first connector 311 connected to the frame 21, a first connecting shaft 312 connected to the first connector 311, and a first reset member 313. The first connecting shaft 312 is detachably connected to the side wall surface 15. The two ends of the first reset member 313 abut against the frame 21 and the first connector 311, respectively, and the first reset member 313 provides a thrust to push the first connector 311 toward the receiving space 14. The first connecting shaft 312 is operable to move under the action of an external force to cause the first connector 311 to press against the first reset member 313 and disengage from the side wall surface 15, thereby unlocking the frame 21 from the side wall surface 15.

[0080] In this embodiment, as 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 first connecting shaft 312 is detachably connected to the side wall surface 15. This connection can be either detachably connected to the flanges 112 or detachably connected to the side plates 12. Where possible, the first connecting shaft 312 can be detachably connected to both the flanges 112 and the side plates 12. In other words, the locking device 3 is locked to the flanges 112, or locked to both the flanges 112 and the side plates 12; or locked to only the side plates 12. Furthermore, as... Figure 4 As shown, the height of the folded guide discharge component 2 is basically no higher than the height of the flange 112. The side plate 12 is then folded over the guide discharge component 2. The total height of the folded guide discharge component 2 and the side plate 12 is also basically no higher than the height of the flange 112. Finally, the cover plate 4 of the foldable container 100 is placed on the base 11. Thus, after the entire container is folded, the box 1 still maintains a small folding height, reducing the difficulty of operation for operators and reducing transportation and storage costs.

[0081] Furthermore, such as Figure 10 , Figure 11 , Figure 12 As shown, the direction between the two ends of the first reset member 313 is the first direction, as indicated by arrow A. The locking assembly 31 also includes: a first operating member 314 connected to the first connecting shaft 312, and a receiving platform 151 for receiving the first connecting shaft 312 on the outer side of the side wall 15. Under the action of external force, the first operating member 314, the first connecting member 311, and the first connecting shaft 312 can be operably moved outward along the first direction toward the receiving space 14 to disengage the first connecting shaft 312 from the receiving platform 151 and unlock the frame 21 and the side wall 15.

[0082] In addition, such as Figure 11 , Figure 12 As shown, the first operating member 314 is hinged to the first connecting shaft 312. The outer side of the side wall 15 has a recess 150 for placing the first operating member 314. The recess 150 extends along the height direction of the housing 1, and the receiving platform 151 is located in the recess. Since the first operating member 314 is rotatable, when it is necessary to adjust the guide discharge member 2, the first operating member 314 can be rotated up or down to a suitable position, and then the first connecting shaft 312 can be driven by pulling the first operating member 314. When the guide discharge member 2 has moved to a suitable position and needs to be fixed, the first operating member 314 can be flipped up or down so that the first operating member 314 is embedded in the recess 150 and will not protrude outside the housing 1 to be misoperated or interfere with other external equipment.

[0083] In addition, such as Figure 12As shown, the first connecting member 311 includes: a first connecting body 3111 connected to the first connecting shaft 312, and a first fixing member 3112 connected to the end of the first connecting body 3111 opposite to the first connecting shaft 312. One end of the first resetting member 313 abuts against the first fixing member 3112 and extends toward the side wall surface 15. In this embodiment, the first connecting body 3111 penetrates the side wall surface 15 and is inserted into the frame 21. The first fixing member 3112 is a baffle fixed to the end of the first connecting body 3111 opposite to the first connecting shaft 312 by bolts 3113 or other components. The first resetting member 313 may be a spring sleeved on the first connecting body 3111 and abuts against the first resetting member 313. The frame 21 has a first groove 212, a second groove 213, and a third groove 214 that are interconnected, extending from inside the receiving space 14 to outside the receiving space 14. This direction of the frame 21 from inside the receiving space 14 to outside the receiving space 14 is also the direction in which the first connecting shaft 312 is pulled, separating the first connecting shaft 312 from the side wall 15 of the housing 1. The first fixing member 3112 is movably disposed in the first groove 212, and the first resetting member 313 abuts against the bottom of the first fixing member 3112 and the second groove 213. When the first connecting shaft 312 moves to its limit position (the guide discharge member 2 is unlocked), the first fixing member 3112 abuts against the bottom of the first groove 212, thereby limiting the first fixing member 3112; when the first reset member 313 pulls the first connecting shaft 312 back to its original position, the first fixing member 3112 is also located in the first groove 212, and the first fixing member 3112 does not leave the interior of the frame 21, so the first fixing member 3112 will not affect the discharge of goods.

[0084] Specifically, taking the first operating component 314 as a handle and the first reset component 313 as a spring as an example, such as Figure 9 , Figure 10 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. At the same time, two plates 22 can be supported by the bottom plate 111 of the base 11, and the other two plates 22 can be supported by the gate 13, allowing the plates 22 to tilt. In other embodiments, the plates 22 can all be supported by the bottom plate 111. When discharge is required, the gate 13 is pulled to open the discharge port 10. Since the multiple plates 22 abut against each other and are supported by the bottom plate 111, the plates 22 can maintain an inclined state to allow the goods to be discharged. Figures 9-12 As shown, when it is necessary to unlock and move the guide discharge component 2, the first operating component 314 can be flipped upwards to move it away from the recess 150. Then, by pulling the first operating component 314, the first connecting component 311 moves outwards from the housing 1, compressing the first reset component 313, thus unlocking the guide discharge component 2 and allowing it to slide down. In actual operation… Figures 13-17As shown, the locking component 31 at one end can be operated first to move one side of the guide discharge component 2 downwards, and then the locking component 31 on the other side can be operated to move the other side of the guide discharge component 2 downwards as well, thereby realizing that the entire guide discharge component 2 moves down onto the base 11. During the downward movement, multiple plates 22 are pressed against the bottom plate 111 of the base 11, and the included angle between the plates 22 and the frame 21 becomes smaller, so that multiple plates 22 are folded onto the base 11. As shown in the figure, the discharge space 23 of the folded plates 22 is reduced to almost nothing. Multiple plates 22 are folded onto the base 11, and multiple plates 22 are sequentially arranged to form a bottom opening 20 opposite to the discharge port 10. In the initial state, goods are stored in the box 1, and the guide discharge component 2 can be located in the second preset position ( Figure 16 When goods need to be discharged, the gate 13 is opened, and the bottom opening 20 is connected to the discharge port 10. After the goods inside the container 1 are emptied, the remaining tailings will pull the guide discharge component 2 up to the first preset position and be locked to the side wall 15 of the container 1 by the locking device 3 (e.g., Figure 9 When the guide discharge component 2 forms a funnel shape to assist in the discharge and emptying of tail material, and when the foldable container 100 is stored, the guide discharge component 2 is unlocked and slid down to the second preset position, and finally the box body 1 is folded.

[0085] In other embodiments, a gate may 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 raised using the above method. During the raising process, the multiple plates gradually rise, forming a bottom opening around each other. Partial goods can be discharged first, and after the partial discharge, the guide discharge component can be raised again, gradually increasing the size of the bottom opening. Alternatively, 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 support between the plates and the base plate can be selected according to the actual situation. The guide discharge component can be made of a material with appropriate hardness based on the weight of the goods.

[0086] 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 the locking device and its cooperation structure with the frame 71 of the guide discharge member 7 and the box body 5. For example... Figure 18 , Figure 19 , Figure 20 , Figure 21As shown, the guide discharge component 7's plate 72 and frame 71 are hinged together. The locking assembly 61 includes: a locking tongue 615, a second reset member 613 whose two ends respectively abut against the locking tongue 615 and the frame 71, a second connecting member 611 rotatably connected to the frame 71, and a second operating member 614 fixedly connected to the second connecting member 611. The second reset member 613 provides a thrust to push the locking tongue 615 into the frame 71; the second operating member 614 is rotatably connected to the frame 71 and detachably connected to the side wall surface 55; the second operating member 614 is operably rotated to separate from the side wall surface 55, causing the second connecting member 611 to flip and push the locking tongue 615 away from the side wall surface 55. When the second operating member 614 rotates to engage with the side wall surface 55, the locking tongue 615 locks into the frame 71 to secure the frame 71 to the side wall surface 55.

[0087] Furthermore, such as Figure 20 , Figure 21 , Figure 22 , Figure 23 As shown, the second connecting member 611 has a second connecting body 6111 rotatably connected to the frame 71, and a linkage member 6113 fixedly connected to the second connecting body 6111. The linkage member 6113 is used to flip and push the locking tongue 615 on the second connecting body 6111. The second connecting body 6111 is fixedly connected to the second operating member 614 through the second fixing member 6112. In addition, the locking tongue 615 has a locking tongue guide portion 6151, which facilitates the insertion or withdrawal of the locking tongue 615 from the side wall surface 55. In this embodiment, the second connecting body 6111 and the frame 71 are rotatably connected by a pin 73.

[0088] Furthermore, such as Figure 23 As shown, the outer side of the side wall 55 has multiple slots 552 arranged along the height direction of the housing 5. The slots 552 are used to engage the second operating member 614. In this embodiment, two slots 552 can be provided: one for positioning the second operating member 614 when the guide discharge member 7 is fixed in the first preset position, and the other for positioning the second operating member 614 when the guide discharge member 7 is fixed in the second preset position. In other embodiments, if it is necessary for the guide discharge member 7 to be fixed in multiple positions, more slots 552 can be provided to position the second operating member 614. In another embodiment, slots 552 may not be provided; the second operating member 614 can simply be flipped to a suitable position and the locking tongue 615 can be inserted into the side wall 55.

[0089] In addition, such as Figure 29 , Figure 30 , Figure 31 , Figure 32 , Figure 33 , Figure 34 , Figure 35As shown, the second operating member 614 has a movable cavity 6140, and is connected to the frame 71 via a second connecting shaft 612. When the second operating member 614 engages with the side wall surface 55, the movable cavity 6140 extends along the extending direction of the second reset member 613, and the second connecting shaft 612 is operably movable along the movable cavity 6140. The movable cavity 6140 allows the guide discharge member 7 to be tilted downwards when it moves down, and there is a certain amount of space for rotation between the guide discharge member 7 and the second operating member 614.

[0090] Specifically, taking the second operating element 614 as a handle and the second reset element 613 as a spring as an example, the frame 71 has a cavity, and the second reset element 613 is inserted into the cavity and the locking tongue 615. Figure 20 , Figure 21 As shown, when the guide discharge component 7 is in the first preset position, the second operating component 614 is engaged in the slot 552 on the side wall 55, the locking tongue 615 is inserted into the side wall 55, and the frame 71 is fixed to the side wall 55 of the housing 5. At this time, the guide discharge component 7 is used to provide the function of discharging and discharging goods. Figure 22 , Figure 23 , Figure 24 , Figure 25 , Figure 26 , Figure 27 , Figure 28 As shown, when it is necessary to unlock and move the guide discharge member 7, the second operating member 614 can be flipped downwards, allowing it to leave the slot 552. The second connecting member 611 flips, and the linkage member 6113 presses against the locking tongue 615. The locking tongue 615 is pushed away from the side wall 55, and the second reset member 613 is compressed. The frame 71 is unlocked from the side wall 55, allowing the unlocked side of the guide discharge member 7 to move downwards. Due to the presence of the movable cavity 6140, the second connecting shaft 612 can move within the movable cavity 6140 when the guide discharge member 7 moves downwards. Figures 29-35 This allows one side of the guide discharge component 7 to tilt downwards. When it moves to the second preset position, the second operating component 614 can flip up and lock into the slot 552 below the side wall 55. Then, the locking component 61 on the other side of the guide discharge component 7 is operated again to unlock and lower the other side of the guide discharge component 7, so that the guide discharge component 7 is folded onto the base 51.

[0091] In other embodiments, such as Figure 36 , Figure 37 , Figure 38As shown, a gate may not be necessary. When the guide discharge component is in the second preset position, multiple plates fold onto the base to seal the discharge port. When material needs to be discharged, the guide discharge component can be raised using the above method. During the raising process, multiple plates gradually rise, forming a bottom opening around each other. Partial goods can be discharged first, and after discharge, the guide discharge component can be raised again, gradually increasing the size of the bottom opening. Alternatively, 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 support between the plates and the base plate can be selected according to the actual situation. The guide discharge component can be made of a material with appropriate hardness based on the weight of the goods.
