Description

Technical Field

[0001] This utility model relates to the field of logistics, and in particular to a 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 utility model is to provide a container that facilitates the discharge of goods without occupying internal space.

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

[0005] The enclosure includes: a base with a discharge outlet; two pairs of opposing side panels; the two pairs of side panels forming a receiving space around the base; and

[0006] A guide discharge component is disposed within the receiving space. The guide discharge component has multiple plates, each plate having a support portion and a guide portion connected to the top of the support portion. The guide portion is operably bent and connected to the support portion. The support portions of the multiple plates are sequentially connected around the side wall of the housing. The guide portion and at least a portion of the support portion are operably unfolded or folded relative to the base. When the guide portion and the support portion are unfolded relative to the base, the support portion operably carries the guide portion and supports it on the base. The guide portion operably extends obliquely toward the discharge port. The guide portions of the multiple plates are sequentially adjacent to each other to form a discharge space that connects to the discharge port and has a bottom opening.

[0007] Compared to existing technologies, this invention features a guide discharge component. This component comprises multiple plates, a support portion, and a guide portion. When the guide portion and support portion are unfolded relative to the base, the support portion supports the guide portion, which extends at an angle towards the discharge port. The multiple guide portions surround and form a discharge space, allowing goods to enter and slide down through the guide portions to the discharge port, preventing goods from remaining inside the container. Simultaneously, the guide portion and at least a portion of the support portion fold relative to the base, reducing the height of the guide discharge component. At least a portion of the support portion lies on the base, no longer supporting the guide portion, which also folds down onto the base. This reduces the size of the guide discharge component, minimizing the space occupied and eliminating the need to remove the component to free up space. This reduces the difficulty of operation for personnel and lowers transportation and storage costs.

[0009] In one embodiment, the support portion is provided with a second weak portion; when the guide portion and at least a portion of the support portion are operably folded relative to the base, the connection between the portion of the support portion folded onto the base and the portion of the support portion supported on the base is the second weak portion, the guide portion is operably folded onto the portion of the support portion folded onto the base, and the portion of the support portion folded onto the base avoids the discharge port.

[0010] In one embodiment, the base has a base plate and two pairs of opposing flanges extending upward from the base plate, the two pairs of flanges corresponding to two pairs of side plates, and the side plates being connected to their corresponding flanges; the distance between the first weak portion and the second weak portion is less than the height of the flanges.

[0011] In one embodiment, the distance between the first weak portion and the second weak portion is the thickness of the plate.

[0012] In one embodiment, the guide portion has at least one first elongated groove at the connection point with the support portion, forming the first weak portion; and / or

[0013] The support portion has at least one second long groove forming the second weak portion.

[0014] In one embodiment, when the guide portion and the support portion are unfolded relative to the base, the support portion stands upright on the base and abuts against the side wall of the housing, and the guide portion extends to abut against the bottom plate of the base; or

[0015] The housing further includes: a gate for opening or closing the discharge port; when the guide portion and at least part of the support portion are folded relative to the base, the guide portions of a plurality of the plates sequentially surround each other to form a bottom opening that mates with the discharge port; when the guide portion and the support portion are unfolded relative to the base, the support portion stands upright on the base and abuts against the side wall of the housing, and the guide portion extends to abut against the bottom plate of the base or operably abuts against the gate.

[0016] In one embodiment, the plate has two pairs, each corresponding to one of the two pairs of side plates; when the guide portion and the support portion are unfolded relative to the base, adjacent guide portions abut against each other for support.

[0017] In one embodiment, the plurality of said plates are a single piece connected together.

[0018] In one embodiment, the side plate is hinged to the base and configured to be operably unfolded or folded relative to the base; the plate is a honeycomb panel.

[0019] In one embodiment, the housing further includes: a gate for opening or closing the discharge port, wherein when the guide portion and at least a portion of the support portion are folded relative to the base, the guide portions of the plurality of plates sequentially surround each other to form a bottom opening that engages with the discharge port;

[0036] The embodiments of this utility model are described below with reference to the accompanying drawings.

[0037] One embodiment of this utility model relates to a container 100. For example... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the container 100 includes a housing 1 and a guide discharge member 2. The housing 1 includes a base 11 with a discharge port 10, two pairs of opposing side plates 12, and a gate 13 for opening or closing the discharge port 10. The two pairs of side plates 12 form a receiving space 14 around the base 11. The guide discharge member 2 is disposed within the receiving space 14 and has multiple plates 201, each plate 201 having a support portion 21 and a guide portion 22 connected to the top of the support portion 21. The guide portion 22 is operably bent and connected to the support portion 21. The support portions 21 of the multiple plates 201 are sequentially connected around the side wall surface 15 of the housing 1. The guide portion 22 and at least a portion of the support portion 21 are operably unfolded or folded relative to the base 11. Figure 5 , Figure 6 As shown, when the guide portion 22 and at least part of the support portion 21 are folded relative to the base 11, the guide portions 22 of the plurality of plates 201 sequentially surround each other to form a bottom opening 20 that mates with the discharge port 10. Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, when the guide portion 22 and the support portion 21 are unfolded relative to the base 11, the support portion 21 operably carries the guide portion 22 and supports it on the base 11. The guide portion 22 operably extends obliquely toward the discharge port 10. The guide portions 22 of the multiple plates 201 are sequentially adjacent to each other to form a discharge space 23 that is connected to the discharge port 10 and has a bottom opening 20. When the guide portion 22 and at least part of the support portion 21 are operably unfolded relative to the base 11, i.e., in a state where goods can be guided and discharged, the guide discharge member 2 has a funnel-shaped structure. The guide portion 22 is inclined, and the distance between the top of the guide portion 22 and the side wall surface 15 of the box 1 is less than the distance between the bottom of the guide portion 22 and the side wall surface 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 guide portion 22 can abut against the bottom plate 111 of the base 11, so that the guide portion 22 can be supported. At the same time, each guide portion 22 abuts against its adjacent guide portion 22, so that the goods can be stably guided along the guide portion 22 from the discharge space 23 to the discharge port 10. In this embodiment, when the guide discharge member 2 is unfolded, the angle α between the bottom end of the guide portion 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 13 can be configured as a horizontal push-pull type on the base plate 111 of the base 11 to open or close the discharge port 10, and the gate 13 is also provided with a handle 131 for easy operation.

[0038] To facilitate the discharge of goods, a funnel is usually prefabricated at the bottom of the container 100 used for packaging and transportation. Before filling semi-finished or prefabricated goods, the funnel is placed on the base 11 inside the box body 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 body 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 side wall of the prefabricated funnel 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 to have a fixed height. Therefore, when the funnel is placed in the folding container 100 and the goods inside the box are emptied, the funnel needs to be removed before the folding container 100 can be folded. When the container 100 is relatively large, the funnel fits relatively well with the side wall of the container 100, making it more complicated and laborious to remove the funnel. If the funnel is not removed, its fixed height will occupy space, causing the height of the container 100 to increase after folding, which in turn increases the transportation or storage space of the packaging carrier, and ultimately increases the empty return cost and warehousing cost of the container 100. In this embodiment, the container 100 is equipped with a guide discharge component 2. The guide discharge component 2 has multiple plates, each with a support portion 21 and a guide portion 22. When the guide portion 22 and the support portion 21 are unfolded relative to the base 11, the support portion 21 supports the guide portion 22, and the guide portion 22 extends obliquely towards the discharge port 10. The multiple guide portions 22 surround to form a discharge space 23, allowing goods to enter the discharge space 23 and slide down through the guide portions 22 to the discharge port 10 for discharge, preventing goods from remaining inside the container 1. Simultaneously, the guide portion 22 and at least part of the support portion 21 are folded relative to the base 11, reducing the height of the guide discharge component 2. At least part of the support portion 21 lies on the base 11 and can no longer support the guide portion 22, causing the guide portion 22 to also fold down onto the base 11. At this time, the guide discharge component 2 can be reduced in size, reducing the occupancy of the containment space 14. It is not necessary to remove the guide discharge component 2 to release the containment space 14, reducing the difficulty of operation for personnel and lowering transportation and storage costs.

[0039] The implementation details of this embodiment are described below. The following content is only for the convenience of understanding the implementation details and is not necessary for implementing this solution.

[0040] In this embodiment, as Figure 1 As shown, the side plate 12 is hinged to the base 11 and configured to be operably unfolded or folded relative to the base 11. One pair of side plates 12 are long side plates, and the other pair are short side plates. The long side plate includes a lower plate 122 hinged to the base 11, and an upper plate 121 hinged to the lower plate 122. The upper plate 121 and the lower plate 122 are folded together and operably folded onto the base 11. The short side plates can be similarly folded. Alternatively, the side plate 12 can also be a single, straight plate.

[0041] Furthermore, such as Figure 2 , Figure 6 , Figure 8 As shown, a first weak point 24 is provided at the connection between the guide part 22 and the support part 21. When the support part 21 is vertically supported on the base 11, the guide part 22 and the support part 21 are bent and inclined through the first weak point, extending towards the discharge port 10. The guide part 22 can abut against the bottom plate 111 of the base 11, so that the plate can be supported. At the same time, each guide part abuts against its adjacent guide part, so that the goods can be stably discharged from the discharge space 23 to the discharge port 10 along the guide part.

[0042] In addition, such as Figure 7 As shown, the connection between the guide portion 22 and the support portion 21 has at least one first long groove 240 forming a first weak portion 24. This first long groove 240 extends along the length direction (horizontal direction) of the guide portion 22. In this embodiment, two first long grooves 240 can be provided. Through these two first long grooves 240, the guide portion 22 and the support portion 21 can be folded at the required angle. For example, the guide portion 22 can be tilted to accommodate goods, or it can be directly folded onto part of the support portion 21 and laid flat on the bottom plate 111 of the base 11, thus not occupying space inside the box 1. It is understood that in this embodiment, the formation of the first weak portion through the first long groove 240 is merely an example; the first weak portion 24 could also be a thin area that is easily bent.

[0043] Furthermore, such as Figure 2 , Figure 6 , Figure 8As shown, a second weak point 25 is provided on the support part 21. When the guide part 22 and at least part of the support part 21 are operably folded relative to the base 11, the connection between the portion m of the support part 21 folded onto the base 11 and the portion n of the support part 21 supported on the base 11 is the second weak point 25. The guide part 22 is operably folded onto the portion m of the support part 21 folded onto the base 11, and the portion m of the support part 21 folded onto the base 11 avoids the discharge port 10. That is, when it is necessary to fold the guide discharge member 2 onto the base 11 to avoid occupying space, the support part 21 between the second weak point 25 and the first weak point 24 can still stand on the base 11. The other areas of the support part 21 are bent and laid flat on the bottom plate 111 of the base 11 through the second weak point. The guide part 22 is folded onto the portion m of the support part 21 folded onto the base 11 through the first weak point 24, and the length of the guide part 22 is greater than the portion of the support part 21 folded onto the base 11. When the guide discharge section is folded onto the base 11, the discharge port 10 is not completely blocked. After the gate 13 is opened, the bottom opening 20 is connected to the discharge port 10, allowing goods to be discharged. When the goods are discharged to the tail, the support section 21m folded onto the base 11 can be lifted. The support section 21m is fully supported on the base 11, and the guide discharge section is also supported and tilted towards the discharge port 10, allowing the tail to be discharged along the guide discharge section.

[0044] In addition, such as Figure 7 As shown, the support portion 21 has at least one second long groove 250 forming a second weak portion 25. The second long groove 250 can extend along the length direction (horizontal direction) of the support portion 21. In this embodiment, there can be two second long grooves 250. Through the two second long grooves 250, the support portion 21 can be folded as needed. As shown in the figure, part m of the support portion 21 is folded and laid flat on the bottom plate 111 of the base 11, while the other part n is supported and erected on the bottom plate 111 of the base 11. The formation of the second weak portion through the second long groove 250 is just an example. Alternatively, the second weak portion 25 can be a thinner area that is easy to bend.

[0045] Furthermore, such as Figure 1 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 connected to their corresponding flanges 112. The distance between the first weak part 24 and the second weak part 25 is less than the height of the flanges 112.

[0046] Preferably, the distance between the first weak portion 24 and the second weak portion 25 is equal to the thickness of the plate 201. When the guide portion 22 is folded, it can be folded onto the support portion 21 folded onto the base 11, but the thickness after folding will not be too large.

[0047] like Figure 1 and Figure 3As shown, when the guide portion 22 and the support portion 21 are unfolded relative to the base 11, i.e., when the guide discharge component 2 can be used to discharge goods, the support portion 21 is supported upright on the bottom plate 111 of the base 11. At this time, the support portion 21 is in contact with the side wall surface 15 of the box 1, i.e., the support portion 21 can be in contact with the flange 112, or it can be partially abutting the flange 112 and partially in contact with the side plate 12. In other embodiments, when the base 11 does not have a flange 112, the support portion 21 can be in contact with the side plate 12. In this embodiment, the support portion 21 is in contact with the side wall surface 15 of the box 1; in other embodiments, the support portion 21 can also be close to the side wall surface 15 of the box 1. The guide portion 22 extends to abut against the bottom plate 111 of the base 11 or operably abuts against the gate 13.

[0048] In addition, the plate 201 has two pairs, each corresponding to one of the two pairs of side plates 12. For example... Figure 1 and Figure 3 As shown, when the guide portion 22 and the support portion 21 are deployed relative to the base 11, adjacent guide portions 22 support each other, and adjacent support portions 21 also support each other. In other embodiments, gaps may exist between adjacent support portions 21 and between adjacent guide portions 22.

[0049] Furthermore, such as Figure 7 As shown, multiple panels 201 are connected together as a single unit. Panel 201 can be a honeycomb panel, or it can be an aluminum plate, cardboard, or plastic plate, etc.

[0050] In practical use, such as Figure 5 , Figure 6 As shown, the guide discharge component 2 can be pushed by a rod or manually to allow part of the support 21 to fold down and lay on the base plate 111 of the base 11. With part of the support 21 folded down, the guide 22 folds down to the part of the support 21 folded onto the base plate 111 of the base 11. The guide 22 also lies flat and tilts down. At this time, the guide discharge component 2 is folded down onto the base 11 as a whole, without occupying the space inside the box 1, and goods can be stored in the box 1. When discharging goods, the gate 13 is opened, and the bottom opening 20 communicates with the discharge port 10. After part of the goods inside the box 1 is emptied, when the remaining tail material is discharged, the support 21 folded onto the base 11 is supported upright on the base 11 by a rod or manually. The guide 22 is no longer folded down but unfolded and tilted. Figure 1 and Figure 3 Multiple guide sections are arranged similarly around the receiving space 14 to form a discharge space 23. At this time, the guide discharge component 2 roughly forms a funnel to assist in the discharge and emptying of the tail material. After the goods are emptied, the guide discharge component 2 can be folded onto the base 11. If the side plate 12 is foldable, it can be folded on top of the guide discharge component 2. The cover plate 4 is placed on the folded side plate 12, so that the container 100 can be folded as a whole without taking up space.

[0051] In other embodiments, a gate may be omitted. When the guide portion and at least part of the support portion of the plate are folded relative to the base, the guide portions and / or at least part of the support portions of the multiple plates fold onto the base to cover the discharge port. That is, when the guide discharge component is folded, the guide portion may cover the discharge port, the support portion may cover the discharge port, or the guide portion or at least part of the support portion may cooperate to cover the discharge port. When material needs to be discharged, the portion of the support portion folded onto the base can be supported and erected on the base 11 by external components or manual lifting. At this time, the guide portions of the multiple plates sequentially surround each other to form a bottom opening that aligns with the discharge port, allowing the goods to be discharged. Alternatively, the guide portion can be gradually raised while the support plate is being erected from the base, and the bottom opening gradually forms to begin discharging the goods. The guide discharge component can be made of a plate with appropriate hardness according to the weight of the goods. 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 adopt aspects, features, and concepts of various patents, applications, and publications to provide other embodiments.

[0052] In light of the detailed description above, these and other changes can be made to the embodiments. Generally, the terminology used in the claims should not be considered limited to the specific embodiments disclosed in the specification and claims, but should be understood to include all possible embodiments together with the full scope of equivalents enjoyed by these claims.

[0053] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
