Description

Technical Field

[0001] This invention relates to a container, and more particularly to a container and its side panels. Background Technology

[0002] For existing foldable containers, the maximum height of the side panels generally cannot exceed the length of the base minus the thickness of the side panels; otherwise, it will affect the folding of the side panels (they cannot be folded flat). When the length and width of the base are limited, the maximum height of the side panels is also limited accordingly. To increase the container's volume, it is generally necessary to keep the base's bottom surface unchanged and increase the base height to raise the container and thus increase its volume.

[0003] However, as the base height increases, the total height of the folded container also increases. These types of foldable containers are typically transported via containers or vans during recycling and transfer. The total height of the folded container determines the number that can be packed into the container or van. A higher total height folded means fewer containers can be packed, significantly increasing recycling and transportation costs. Simultaneously, in warehousing management, the total height of the folded container determines the number that can be stacked in the warehouse. A higher total height folded means fewer containers can be stacked in the warehouse, increasing not only warehousing costs but also indirectly raising the container's turnover cost.

[0004] In addition, increasing the height of the side panels can also increase the container's volume. However, the increased height of the side panels, when folded, exceeds the length and width of the base, necessitating folding the side panels in half before folding again. This method not only increases the number of steps and the difficulty of operation, but also, as the thickness of the side panels increases after folding, the base must be raised accordingly, further increasing the total height of the folded container and significantly reducing its recycling rate. Summary of the Invention

[0005] The purpose of this invention is to provide a container and its side panel, such that the upper part of the side panel is adjustable without increasing the thickness of the side panel.

[0006] To address the aforementioned technical problems, embodiments of the present invention provide a side plate for a container, comprising:

[0007] A first plate, the first plate having a first limiting surface;

[0008] A second plate body is arranged with the first plate body along the height direction of the side plate; the second plate body has a main plate and an extension plate located on the side of the main plate facing the first plate body; the extension plate and the first plate body are slidably connected along the height direction of the side plate.

[0009] The third plate is hinged to the second plate via a hinge shaft that extends along the horizontal length of the side plate.

[0010] In this process, the extension plate slides along the first plate to a first position, the side plate height decreases, the third plate is flipped and attached to the outer surface of the first plate, and the first plate and the third plate are positioned together; the extension plate slides along the first plate to a second position, the side plate height increases, the third plate is flipped and abuts against the first limiting surface, and the first plate and the third plate are positioned together.

[0011] Compared to existing technologies, this invention's embodiments differ in that the extension plate can slide along the first plate. When a shorter side plate is needed, the extension plate slides down, shortening the distance between the main plate and the first plate. Then, the third plate is flipped to fit against the outer surface of the first plate. At this point, the third plate, close to the first plate, along with the second plate above the first plate, forms a shorter plate. When a taller plate is needed, the second plate is pulled, allowing the extension plate to slide to a second position. Then, the third plate is flipped to abut against the first limiting surface. At this point, the third plate acts as a limiting element, supporting the extension plate between the main plate and the first plate, preventing further slide of the extension plate, thus forming a taller plate. When the side plate forms both tall and short plates, it does not require folding, nor does it increase the thickness of the side plate.

[0012] In one embodiment, the first plate has a first layer plate portion and a second layer plate portion disposed opposite to each other along the thickness direction of the side plate; the first layer plate portion and the second layer plate portion are spaced apart to form a channel;

[0013] The extension plate has an insertion portion that is inserted into the channel; the third plate body is disposed on the side of the insertion portion facing the first plate layer.

[0014] In one embodiment, the extension plate further has a back plate portion spaced apart from the insertion portion along the thickness direction of the side plate; the second layer plate portion is inserted between the insertion portion and the back plate portion.

[0015] In one embodiment, the first limiting surface is located on the top surface of the first layer plate portion.

[0016] In one embodiment, the first layer plate has an upper section plate arranged along the height direction of the side plate and a lower section plate connected to the upper section plate; the outer surface of the upper section plate away from the second layer plate is offset relative to the outer surface of the upper section plate away from the second layer plate towards the channel direction to form a recess; the third plate can be flipped about the hinge axis into the recess;

[0017] The extension plate slides along the first plate to a first position, and the upper section abuts against the third plate.

[0018] In one embodiment, the bottom surface of the recessed portion is a second limiting surface; the extension plate slides along the first plate to a first position, and the third plate flips so that the recessed portion abuts against the second limiting surface.

[0019] In one embodiment, the sum of the thickness of the third plate and the thickness of the upper section is less than or equal to the thickness of the lower section.

[0020] In one embodiment, along the thickness direction of the side plate, the outer surface of the second plate extends out of the insertion portion along the height direction.

[0021] In one embodiment, the first layer plate has an upper section plate arranged along the height direction of the side plate and a lower section plate connected to the upper section plate; the outer surface of the upper section plate away from the second layer plate is offset relative to the outer surface of the upper section plate away from the second layer plate towards the channel direction to form a recess; the third plate can be flipped about the hinge axis into the recess;

[0022] The outer surface of the second plate extends along the height direction and is located on the same plane as the outer surface of the lower plate.

[0023] In one embodiment, the outer surface of the extension plate is recessed inward to form a recess for mounting the hinge shaft; the top end of the third plate is sleeved on the hinge shaft and located in the recess.

[0024] In one embodiment, the extension plate and the main plate are an integral part; or the extension plate and the main plate are two independent components.

[0025] An embodiment of the present invention also provides a container, the container being a foldable container, comprising:

[0026] Base;

[0027] Two pairs of side plates, which are opposite each other and form a receiving space around the base, and each of the side plates is folded and connected to the base; wherein at least one of the side plates is a side plate as described in any of the above.

[0030] A second plate body is arranged with the first plate body along the height direction of the side plate; the second plate body has a main plate and an extension plate located on the side of the main plate facing the first plate body; the extension plate and the first plate body are slidably connected along the height direction of the side plate.

[0031] The third plate is hinged to the first plate via a hinge shaft that extends along the horizontal length of the side plate.

[0032] In this process, the extension plate slides along the first plate to a first position, the side plate height decreases, and the third plate is flipped to attach to the outer surface of the first plate; the extension plate slides along the first plate to a second position, the side plate height increases, and the third plate is flipped to position itself with the second plate.

[0034] The extension plate slides along the first plate to a second position, and flips the third plate to abut against the second limiting surface. In one embodiment, the first plate has a first layer plate portion and a second layer plate portion disposed opposite to each other along the thickness direction of the side plate; the first layer plate portion and the second layer plate portion are spaced apart to form a channel;

[0035] The extension plate has an insertion portion that inserts into the channel; the third plate is hingedly connected to the first layer plate.

[0036] In one embodiment, the extension plate further has a back plate portion spaced apart from the insertion portion along the thickness direction of the side plate; the second layer plate portion is inserted between the insertion portion and the back plate portion.

[0037] In one embodiment, the first layer plate has an upper section plate arranged along the height direction of the side plate and a lower section plate connected to the upper section plate; the outer surface of the upper section plate away from the second layer plate is offset relative to the outer surface of the upper section plate away from the second layer plate towards the channel direction to form a recess; the third plate can be flipped around the hinge axis into the recess.

[0038] In one embodiment, the sum of the thickness of the third plate and the thickness of the upper section is less than or equal to the thickness of the lower section.

[0058] Embodiments of the present invention are described below with reference to the accompanying drawings.

[0059] One embodiment of the present invention relates to a side plate 101 of a container 100. For example... Figure 1 , Figure 4As shown, container 100 is a foldable container, including: a base 6, a pair of opposing first side plates and a pair of opposing second side plates 102. The first side plates 101 and second side plates 102 form a receiving space around the base 6, and the first side plates 101 and second side plates 102 are folded and connected to the base 6. The first side plate 101 can be the same as in this embodiment, so that when folded onto the base 6, the height of the first side plate 101 can be reduced, facilitating folding. In other embodiments, the second side plate 102 of container 100 can also be the same as in this example.

[0060] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the side plate 101 of the container 100 includes: a first plate 2, a second plate 3, and a third plate 4. The first plate 2 has a first limiting surface 20. The second plate 3 is arranged with the first plate 2 along the height direction of the side plate 101. The second plate 3 has a main plate 31 and an extension plate 32 located on the side of the main plate 31 facing the first plate 2, and the extension plate 32 is slidably connected to the first plate 2 along the height direction of the side plate 101. The third plate 4 is hinged to the second plate 3 via a hinge shaft 5, which extends along the horizontal length direction of the side plate 101. Wherein, as... Figure 4 and Figure 5 In the middle, the extension plate 32 slides along the first plate 2 to the first position. At this time, the side plate 101 is a short plate, and the height of the side plate 101 is reduced. The third plate 4 is flipped to abut against the first plate 2, and the outer surface of the third plate 4 is attached to the first plate 2. The first plate 2 and the third plate 4 are positioned. Figure 1 and Figure 2 The middle extension plate 32 slides along the first plate 2 to the second position, the side plate 101 increases in height, and the third plate 4 flips to abut against the first limiting surface 20. The first plate 2 and the third plate 4 are fixed together, and the third plate 4 is close to the extension plate 32. Specifically, when the side plate 101 is a short plate, the third plate 4 is against the outer surface of the first plate 2, the first plate 2 and the third plate 4 abut against each other, the extension plate 32 will not slide down further, the third plate 4, the first plate 2 and the second plate 3 form a whole plate, and the third plate 4 will not protrude outward. When the side plate 101 is a high plate, the first plate 2 is pulled upward, and the extension plate 32 slides out part of the first plate 2. The third plate 4 is flipped so that the third plate 4 abuts against the first limiting surface 20. At this time, one end of the third plate 4 is positioned by the extension plate 32 in the height direction, and the other end is positioned by the first limiting surface 20. That is, the third plate 4 is positioned, and the extension plate 32 will no longer slide down, so that the side plate 101 is a stable high plate and the third plate 4 will not protrude outward.

[0061] From the above, it is easy to see that since the extension plate 32 can slide along the first plate 2, when the side plate 101 needs to become a short plate, the extension plate 32 slides down, shortening the distance between the main plate 31 and the first plate 2. Then, the third plate 4 is flipped up to be in contact with the outer surface of the first plate 2. At this time, the third plate 4 is close to the first plate 2, and together with the second plate 3 located above the first plate 2, they form a short plate. When a tall plate is needed, the second plate 3 can be pulled, allowing the extension plate 32 to slide up to the second position. Then, the third plate 4 is flipped up to abut against the first limiting surface 20. At this time, the third plate 4 acts as a limiting element, supporting the main plate 31 and the first plate 2. The extension plate 32 can no longer slide down, thus forming a tall plate. When the side plate 101 forms both a tall and short plate, the side plate 101 does not need to be folded, nor does it increase the thickness of the side plate 101.

[0062] Furthermore, such as Figure 2 and Figure 3 As shown, the first plate 2 has a first layer plate portion 21 and a second layer plate portion 22 disposed opposite to each other along the thickness direction of the side plate 101, and the first layer plate portion 21 and the second layer plate portion 22 are spaced apart to form a channel 23. The extension plate 32 has an insertion portion 321 for inserting into the channel 23, and the third plate 4 is disposed on the side of the insertion portion 321 facing the first plate layer. Given the channel 23, in order to ensure the strength of the side plate 101, the insertion portion 321 may have multiple portions arranged along the thickness direction of the side plate 101.

[0063] In addition, such as Figure 2 and Figure 3 As shown, the extension plate 32 also has a back plate portion 322 that is spaced apart from the insertion portion 321 along the thickness direction of the side plate 101, and the second layer plate portion 22 is inserted between the insertion portion 321 and the back plate portion 322. This ensures the strength and stability of the side plate 101.

[0064] Furthermore, such as Figure 2 As shown, the first limiting surface 20 is located on the top surface of the first layer plate portion 21. Therefore, when the extension plate 32 slides along the first plate body 2 to the second position, i.e., when the side plate 101 is a high plate, the third plate body 4 abuts against the top surface of the first layer plate portion 21, preventing the extension plate 32 from sliding further downwards, thus forming a stable high plate. When the third plate body 4 is flipped so that it no longer abuts against the top surface of the first layer plate portion 21, the extension plate 32 slides downwards to the first position, and the side plate becomes a low plate. To form a high plate, the second plate body can be manually pulled upwards, allowing the extension plate 32 to slide upwards to the second position.

[0065] Specifically, such as Figure 5 and Figure 6As shown, the first layer plate 21 has an upper section plate 211 arranged along the height direction of the side plate 101 and a lower section plate 212 connected to the upper section plate 211. The outer surface of the upper section plate 211 facing away from the second layer plate 22 is offset relative to the outer surface of the upper section plate 211 facing away from the outer surface of the second layer plate 22 towards the channel 23 to form a recessed portion 213. The third plate 4 can be flipped around the hinge axis 5 into the recessed portion 213, and the outer surface of the second layer plate 22 faces the side inside the container 100. Thus, when the extension plate 32 slides along the first plate 2 to the first position, that is, when the side plate 101 forms a short plate, flipping the third side plate 101 into the recessed portion 213 can ensure the overall thickness of the side plate 101 in the short plate state, and the third plate 4 will not protrude outward. In addition, when the extension plate 32 slides along the first plate 2 to the first position, the upper section abuts against the third plate 4.

[0066] Furthermore, such as Figure 5 and Figure 6 As shown, the bottom surface of the recessed portion 213 is the second limiting surface 214. The extension plate 32 slides along the first plate 2 to the first position, and the third plate 4 flips over so that the recessed portion 213 abuts against the second limiting surface 214.

[0067] In addition, such as Figure 5 and Figure 6 As shown, the sum of the thickness of the third plate 4 and the thickness of the upper section is less than or equal to the thickness of the lower section.

[0068] In addition, such as Figure 2 and Figure 3 As shown, along the thickness direction of the side plate 101, the outer surface of the second plate 3 extends outward in the height direction beyond the insertion portion 321. That is, the outer surface of the second plate 3 faces outward from the container 100, and this surface extends outward in the height direction beyond the insertion portion 321. When the third plate 4 is flipped to extend along the height direction of the side plate 101, the outer surface of the third plate 4 and the outer surface of the second plate 3 can be approximately on the same plane. The sum of the thicknesses of the third plate 4 and the extension plate 32 along the sliding portion of the first plate 2 is equal to or approximately equal to the thickness of the second plate 3. Therefore, when the side plate 101 is a high plate, the overall feel of the side plate 101 is stronger, and the presence of the flippable third plate 4 will not cause a large difference in thickness between the top and bottom of the side plate 101, thus ensuring the strength of the side plate 101 and improving its stability in use.

[0069] Furthermore, such as Figure 5 and Figure 6 As shown, the extension surface of the outer surface of the second plate 3 in the height direction is located on the same plane as the outer surface of the lower plate 212.

[0070] In addition, such as Figure 5 and Figure 6As shown, the outer surface of the extension plate 32 is recessed inward to form a recess 323 for mounting the hinge shaft 5. The top end of the third plate 4 is fitted onto the hinge shaft 5 and located in the recess 323. The recess 323 is located near the top of the extension plate 32, meaning the hinge shaft 5 is located near the top of the extension plate 32. The top end of the extension plate 32 extends outward from the container 100, covering the second plate 3 above the hinge shaft 5. The third side plate 101 flips downward and abuts against the first limiting surface 20 for positioning. This results in a better overall appearance of the outer surface of the side plate 101, with fewer protruding areas, and the side plate 101 is more robust and stable.

[0071] Furthermore, the extension plate 32 and the main plate 31 are two independent components, which are fixedly connected together to form the second plate 3, and can be connected together by adhesive or inserts. In other embodiments, the extension plate 32 and the main plate 31 can be a single piece.

[0072] In this example, the outer surfaces of the first layer plate 21, the first plate 2, and the second plate 3 can be surfaces located outside the container 100. Of course, when the side plate 101 is mounted on the base 6, the third plate 4 can be placed on the side facing inwards from the container 100 as needed.

[0073] In the embodiment of the other side plate, the structure of the side plate is roughly the same as that of the above embodiment. The main difference is that in the side plate involved in the above embodiment, the third plate 4 is hinged to the second plate 3. When the first side plate forms a high plate, the third plate 4 is flipped downward to abut against the first plate 2. In the other side plate, the third plate 4 can also be hinged to the first plate 2 through a hinge shaft. When the side plate forms a high plate, the third plate 4 is flipped upward to be positioned with the second plate 3.

[0074] The third plate 4 is positioned relative to the second plate 3. This positioning can be achieved through a snap-fit ​​mechanism using protrusions and recesses, or by adding a fixing buckle. Alternatively, a second limiting surface can be provided on the second plate 3, allowing the top surface of the third plate 3 after it is flipped upwards to abut against the second limiting surface. The weight of the second plate 3 then presses down on the third plate 4, thus achieving the positioning of the third plate 4 relative to the second plate 3. Specifically, the second limiting surface can be located on the bottom surface of the main plate 31, that is, the bottom surface of the portion of the main plate 31 that protrudes beyond the extension plate 32. Figure 6 For example, the top surface of the recess 323. A protrusion can be provided on the side of the third plate 4 opposite to its hinge with the first plate (i.e., the top surface of the third plate after it is flipped upwards), and a notch can be provided on the second limiting surface to allow the protrusion to engage with the notch, further positioning the third plate 4 and the second plate 3. When the side plate forms a short plate, the third plate 4 can be flipped downwards to the outer surface of the first plate (similar to...). Figure 5In the middle section (where the third plate 4 is hinged to the top of the first plate 2), the extension plate 32 slides down to the first position. In this side plate, the first plate 2 includes a first layer plate portion 21 and a second layer plate portion 22. The first layer plate portion 21 has an upper section plate 211 and a lower section plate 212 connected to the upper section plate 211. The construction of the recessed portion 213 is the same as the side plate structure in the above embodiment, and will not be described in detail here. The sliding connection structure between the extension plate and the first plate is the same as the side plate structure in the above embodiment, and will not be described in detail here.

[0075] Furthermore, the sum of the thickness of the third plate 4 and the thickness of the upper section 211 is less than or equal to the thickness of the lower section 212.

[0076] Since the extension plate can slide along the first plate, when a short side panel is needed, the extension plate slides down, shortening the distance between the main plate and the first plate. Then, the third plate is flipped up to be in contact with the outer surface of the first plate. At this point, the third plate, close to the first plate, and the second plate above the first plate form a short panel. When a tall panel is needed, the second plate is pulled, allowing the extension plate to slide up to the second position. Then, the third plate is flipped up to be positioned with the second plate. At this point, the third plate acts as a limit, supporting the extension plate between the main plate and the first plate, preventing the extension plate from sliding down further, thus forming a tall panel. When the side panel forms both tall and short panels, it does not need to be folded in half, nor does it increase the thickness of the side panel.

[0077] Another embodiment of the present invention relates to a container. The container is a foldable container, comprising: a base, a pair of opposing first side panels, and a pair of opposing second side panels. The pair of first side panels and the pair of second side panels are arranged opposite each other around the base to form a receiving space, and the first and second side panels are folded and connected to the base. At least one of the pair of first side panels and the pair of second side panels is any type of side panel as described in the above embodiments.
