[0001] Related applications are cross-referenced.

[0002] This application was filed on July 16, 2021, has application number 2021108064143, and claims priority to a Chinese patent application for the invention "Container and Side Plate Thereof," the entire text of which is incorporated herein by reference.

[0003] The present invention relates to a storage device, and more particularly to a container and its side panels. [Background technology]

[0004] Modern collapsible bulk containers are typically made from a composite of plastic and metal reinforcement, with volumes ranging from approximately 250 to 1250 liters. These neutral composite bulk containers are referred to as IBCs. A collapsible IBC has a bottom and two pairs of collapsible side panels, preferably with a small door mechanism for easy loading and unloading. To meet hygiene and strength requirements, the side panels are typically two-layer welded, with flat surfaces on both the inside and outside. Currently, two known welding processes are hot plate welding and vibration friction welding. Vibration friction welding is our preferred method due to its high production efficiency and lack of smoke and odor pollution. Structurally, vibration friction welding requires one layer of the two side panels to be thick and the other thin, while hot plate welding requires the two side panels to be approximately the same thickness.

[0005] In vibration friction welding, a reinforcing metal tube is sandwiched between two layers of side panels. The metal tube is typically steel or aluminum, and the inner and outer side panels are welded together to sandwich and secure the reinforcing member. The inner layer is thick and the outer layer is thin. After fluid or semi-fluid cargo is placed inside the IBC, the cargo exerts an outward force on the side panels. During transportation, the IBC is subjected to inertial impact forces, causing significant deformation of the side panels. The ends of the metal tube apply a reaction force to the outer side panels through a fixed support force transmission method. This results in obvious protrusions at the ends of the steel tube, creating stress whitening, potentially posing a risk to the service life of the side panels and the safety of the box. Summary of the Invention

[0006] An object of the present invention is to provide a container and its side plate which are less likely to whiten and can be used more safely.

[0007] In order to solve the above technical problems, an embodiment of the present invention provides a side plate of a container, and the side plate of the container comprises: a first plate; a second plate body that is disposed opposite to and connected to the first plate body and has a thickness greater than that of the first plate body; at least one first reinforcing member disposed within the second plate; and a connecting member connected to the second plate for operably securing at least one of the first reinforcing members within the second plate.

[0008] In one embodiment, a first mounting groove for mounting the first reinforcing member is provided within the second plate, and the connecting member is connected to a first groove wall of the first mounting groove to fix at least one of the first reinforcing members within the first mounting groove.

[0009] In one embodiment, the first mounting groove has a pair of first groove walls spaced apart from each other, and the first reinforcing member is mounted between the pair of first groove walls, and a first notch is provided on the upper surface of the first reinforcing member, and the connecting member is mounted within the first notch, and both ends of the connecting member are inserted into the two first groove walls, respectively.

[0010] In one embodiment, the first reinforcing member is elongated, and the first notch is formed at both ends of the first reinforcing member.

[0011] In one embodiment, each of the first groove walls has a plurality of pin holes arranged side by side in the extension direction of the first mounting groove, and the connecting member is operably inserted into the pin holes.

[0012] In one embodiment, the connecting member has a protruding position limiting buckle.

[0013] In one embodiment, the connecting member is provided with an annular positioning flange on its outer periphery.

[0014] In one embodiment, the connecting member is slotted.

[0015] In one embodiment, both ends of the first reinforcing member are fixed to the second plate body by the connecting member.

[0016] In one embodiment, the side plate further includes a second reinforcing member provided within the second plate body, and the first plate body and the second plate body cooperate to sandwich the second reinforcing member.

[0017] In one embodiment, the second reinforcing member has a reinforcing body portion and extension portions provided at both ends of the reinforcing body portion, and an upper surface of the extension portions is lower than an upper surface of the reinforcing body portion, The first plate has a pair of first cushion ribs that are operably abutted against the upper surfaces of the two extensions, respectively.

[0018] In one embodiment, a second mounting groove for mounting the second reinforcing member is formed in the second plate, A pair of second cushion ribs are provided in the second mounting groove, and the pair of second cushion ribs cooperate with the pair of first cushion ribs to sandwich the second reinforcing member.

[0019] In one embodiment, the second plate body has a plurality of sequentially arranged second horizontal ribs and a plurality of sequentially arranged second vertical ribs, and the second horizontal ribs and the second vertical ribs are arranged in a staggered pattern, wherein at least two adjacent second horizontal ribs are spaced apart from each other to form the second mounting groove, and at least two adjacent second vertical ribs are spaced apart from each other to form a first mounting groove for mounting the first reinforcing member; the first plate body has a plurality of first transverse ribs arranged in sequence, and at least two of the plurality of first transverse ribs are connected by welding to two adjacent second transverse ribs that form the second mounting groove, respectively; The height of the two second vertical ribs forming the first mounting groove is greater than the height of the two second horizontal ribs forming the second mounting groove.

[0020] In one embodiment, the first reinforcing member is disposed perpendicular to the second reinforcing member, and the second reinforcing member is located at the top end of the first reinforcing member.

[0021] In one embodiment, the first reinforcing member is a metal tube and / or the second reinforcing member is a metal tube.

[0022] An embodiment of the present invention further provides a container comprising at least one side panel as described above, wherein a first plate of the side panel faces outward from the container and a second plate of the side panel faces inward from the container.

[0023] In comparison with the prior art, the embodiment of the present invention has a feature in that the connecting member is connected to the second plate and fixes the first reinforcing member to the second plate. Therefore, when an impact force received by the second plate is transmitted to the first reinforcing member, the first reinforcing member transmits the impact force to the connecting member, which then transmits the impact force to the second plate. As a result, the impact force of the first reinforcing member is transmitted mainly to the second plate, and the second plate receives the force. When the first reinforcing member receives the impact force and presses the first plate, the pressed portion of the first plate at the end of the first reinforcing member does not turn white. This allows the first plate to be used for a longer period of time and makes the container safer to use. [Brief explanation of the drawings]

[0033] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0034] 1 and 2, the side panel 10 of the container according to the first embodiment includes a first plate 1, a second plate 2, at least one first reinforcing member 5, and a connecting member 3. The second plate 2 is disposed opposite and connected to the first plate 1, and the thickness of the second plate 2 is greater than the thickness of the first plate 1. The first reinforcing member 5 is disposed within the second plate 2, and the connecting member 3 is connected to the second plate 2 to operably fix the at least one first reinforcing member 5 within the second plate 2.

[0035] From the above, when the connecting member 3 is connected to the second plate 2 and the connecting member 3 fixes the first reinforcing member 5 to the second plate 2, if an impact force received by the second plate 2 is transmitted to the first reinforcing member 5, the first reinforcing member 5 transmits the impact force received by the connecting member 3, and the connecting member 3 transmits the impact force received by the second plate 2, the impact force of the first reinforcing member 5 is transmitted mainly to the second plate 2, and the second plate 2 receives force, and the first reinforcing member 5 receives force and presses the first plate 1, the portion of the first plate 1 pressed by the end of the first reinforcing member 5 is prevented from turning white, and the first plate 1 can be used for a longer period of time, making the container safer to use.

[0036] 4 and 5, the second plate 2 has a first mounting groove 21 for mounting the first reinforcing member 5, and the connecting member 3 is connected to a first groove wall 22 of the first mounting groove 21, and at least one first reinforcing member 5 is fixed in the first mounting groove 21. In other embodiments, the connecting member 3 may be connected to another part of the second plate 2; for example, the connecting member 3 may press the first reinforcing member 5 and connect the connecting member 3 to a panel of the second plate 2, or the first mounting groove 21 may not be provided in the second plate 2, and the first reinforcing member 5 and the second plate 2 may be connected by the connecting member 3.

[0037] 2, 4, 5, 6, and 7, the first mounting groove 21 has a pair of first groove walls 22 that are spaced apart from each other, and the first reinforcing member 5 is mounted between the pair of first groove walls 22. The first reinforcing member 5 has a first notch 51 on its upper surface, and the connecting member 3 is mounted in the first notch 51, with both ends of the connecting member 3 inserted into the two first groove walls 22, respectively. In other embodiments, the connecting member 3 may be fixed to the second plate 2 in other forms; for example, it is understood that a through-hole through which the connecting member 3 passes is opened (drilled) in the first reinforcing member 5, and the connecting member 3 passes through the first groove wall 22 and the first reinforcing member 5.

[0038] Preferably, as shown in FIGS. 2 and 4 , both ends of the first reinforcing member 5 are fixed to the second plate 2 by connecting members 3. Specifically, a first notch 51 is formed at both ends of the first reinforcing member 5. The first reinforcing member 5 may be elongated, square, or have any other irregular shape. Specifically, in this embodiment, as shown in FIGS. 2 , 4 , 5 , 6 , and 7 , the first reinforcing member 5 may be a metal pipe, such as an iron pipe or an aluminum pipe. It is understood that the first reinforcing member may also be a plastic pipe. A connecting member 3 is pressed and held in each of the first notches 51 at both ends of the first reinforcing member 5, thereby fixing both ends of the first reinforcing member 5. In addition, the number of connecting members 3 extruded per end of the first reinforcing member 5 may be multiple, or of course, only one. In other embodiments, it is understood that other positions of the first reinforcing member 5 may be fixed to the second plate body 2 by the connecting member 3, for example, by drilling a notch in the middle region of the first reinforcing member 5, fitting the connecting member 3 into the first notch 51, and then inserting it into the two first groove walls 22 to press and hold the second plate body 2 against the first mounting groove 21 and fix it.

[0039] 2, 3, 4, 5, 6, and 7, the connecting member 3 may be a latch pin, and each first groove wall 22 has a plurality of pin holes 220 formed side by side in the extension direction of the first mounting groove 21, and the connecting members 3 are operably inserted into the pin holes 220. This allows a plurality of connecting members 3 to be provided so as to stably fix the first reinforcing member 5, and different portions of the first reinforcing member 5 may be fixed by selecting appropriate pin holes 220.

[0040] 3, a positioning flange 32 is provided annularly on the outer periphery of the connecting member 3. After the connecting member 3 is attached to a predetermined position, it is inserted into the two first groove walls 22 to press and hold the first reinforcing member 5, and then the flange abuts against the side of one of the first groove walls 22 opposite to the first attachment groove, thereby regulating the position of the connecting member 3.

[0041] 3, 6, and 7, the connecting member 3 is further provided with a protruding position limiting buckle 33. After the connecting member 3 is attached, the position limiting buckle 33 abuts against the side of one of the first groove walls 22 facing the first mounting groove and becomes hooked around the pin hole 220, thereby preventing the connecting member 3 from coming off the first groove wall 22 after attachment. When attaching the connecting member 3, as the connecting member 3 is inserted into the pin hole 220, the position limiting buckle 33 is also pushed into the pin hole 220, and after the connecting member 3 is inserted into a predetermined position, the position limiting buckle 33 comes off the pin hole 220 again and hooks around the pin hole 220.

[0042] Specifically, as shown in Figures 3, 6, and 7, the flange and the position limiting buckle 33 work together to sandwich one first groove wall 22 between the flange and the position limiting buckle 33, thereby stably connecting the connecting member 3 and the second plate body 2 and also stably fixing the first reinforcing member 5.

[0043] It is understood that in other embodiments, either the positioning flange 32 or the position limiting buckle 33 may be provided, and when only the positioning flange 32 is provided, a fixing sleeve may be provided at the end of the connecting member 3 where the positioning flange 32 is not present, and the fixing sleeve may be fitted onto the end of the connecting member 3 where the positioning flange 32 is not present, thereby fixing the connecting member 3 to the second plate body 2 so that the connecting member 3 cannot slip out from the two first side walls. Similarly, when only the position limiting buckle 33 is provided, the connecting member 3 is similarly fixed to the second plate body 2 by the fixing sleeve. Of course, the connecting member 3 may also be fixed to the second plate body 2 by other connection methods such as welding or screwing.

[0044] Furthermore, as shown in Figures 3, 6 and 7, by opening a slot 34 in the connecting member 3, the connecting member 3 is given elasticity so that the connecting member 3 can be easily attached to and detached from the first groove wall 22.

[0045] In other embodiments, the connecting member 3 may be a latch pin or a locking member such as a bolt. Alternatively, the connecting member 3 may include a protruding member fixed to the first reinforcing member 5 and a bolt detachably connected to the first reinforcing member 5, with the protruding member inserted into one of the first groove walls 22 and the bolt inserted into the other first groove wall 22 and locked to the first reinforcing member 5 with a screw.

[0046] Furthermore, the first reinforcing member 5 may be one or more, and all may be connected to the second plate body 2 in the fixed manner described above. Here, the first reinforcing member 5 may be installed either vertically or horizontally, or, in the case of multiple first reinforcing members 5, the extension lines of the tubes of the first reinforcing members 5 may be configured to form any angle.

[0047] The second embodiment of the present invention relates to a side panel 20 of a container. The second embodiment is substantially similar to the first embodiment, with the main difference being that the first embodiment does not include the second reinforcing member 6. On the other hand, in the second embodiment of the present invention, the side panel 20 further includes a second reinforcing member 6 provided on the second plate body 2, as shown in Figures 8, 9, and 10, and the first plate body 1 and the second plate body 2 cooperate to sandwich the second reinforcing member 6. In this example, the second reinforcing member 6 is a metal pipe, such as an iron pipe or an aluminum pipe. It is understood that the second reinforcing pipe may also be a plastic pipe.

[0048] 8, 9, and 10, the second reinforcing member 6 has a reinforcing main body portion 61 and extension portions 62 provided on both ends of the reinforcing main body portion 61 and having upper surfaces lower than the upper surface of the reinforcing main body portion 61, and the first plate 1 has a pair of first cushion ribs 13 that operably abut against the upper surfaces of the two extension portions 62, respectively. The extension portions 62 are sandwiched between the first cushion ribs 13 and the second plate 2.

[0049] 8, 9, and 10, a second mounting groove 23 for mounting the second reinforcing member 6 is formed in the second plate 2, and a pair of second cushion ribs (not shown) are provided in the second mounting groove 23 to cooperate with the pair of first cushion ribs 13 to sandwich the second reinforcing member 6. This fixes the second reinforcing member 6. The provision of the second mounting groove 23 also limits the position of the second reinforcing member 6, preventing it from moving and facilitating the installation of the second reinforcing member 6.

[0050] Furthermore, as shown in Figures 8, 9 and 10, the second plate body 2 has a plurality of second horizontal ribs 25 arranged in sequence and a plurality of second vertical ribs 26 arranged in sequence, the second horizontal ribs 25 and the second vertical ribs 26 are arranged in a staggered pattern, at least two adjacent second horizontal ribs 25 are spaced from each other to form a second mounting groove 23, the two second horizontal ribs 25 forming the second mounting groove 23 are second groove walls 24, at least two second vertical ribs 26 are spaced from each other to form a first mounting groove 21 in which the first reinforcing member 5 is placed, and the two second vertical ribs 26 forming the first mounting groove 21 are first groove walls 22. In the following, as shown in Figures 10, 11, 12, 13 and 14, the two second horizontal ribs 25 forming the second mounting groove 23 are described as second groove walls 24, and the two second vertical ribs 26 forming the first mounting groove 21 are described as first groove walls 22. The thickness of the second plate body 2 in the area of ​​the first groove wall 22 in the figures is D1, and the thickness of the second plate body 2 in the area of ​​the second groove wall 24 is D2. The height of the first groove wall 22 is higher than the height of the second groove wall 24, so that D1 is greater than D2. The first plate body 1 has a plurality of first transverse ribs 11 arranged in sequence and a plurality of second longitudinal ribs 26 arranged in sequence, and the height of the first transverse rib 11 welded to correspond to the second groove wall 24 is higher than the other first transverse ribs 11 and the first longitudinal rib 12, i.e., the height of the first plate body 1 corresponding to the first transverse rib 11 welded to correspond to the second groove wall 24 is D4, and the height of the first plate body 1 corresponding to the other first transverse ribs 11 is D3, and D4 is greater than D3.

[0051] From the above, it can be seen that the area of ​​the first plate 1 corresponding to the end of the second reinforcing member 6 is thick, and after the first reinforcing member 5 is subjected to an impact force, the area of ​​the first plate 1 corresponding to the end of the first reinforcing member 5 is less likely to turn white. Moreover, the other areas of the first plate 1 remain thin, and no noticeable shrinkage marks appear on the surface.

[0052] The second reinforcing member 6 may be one or more, and each may be connected to the second plate body 2 in the fixed manner described above. Here, the first reinforcing member 5 may be installed either vertically or horizontally, or, in the case of multiple second reinforcing members 6, the extension lines of the second reinforcing members 6 may be configured to form any angle.

[0053] Furthermore, the first reinforcing member 5 is installed perpendicular to the second reinforcing member 6, and the second reinforcing member 6 is located at the upper end of the first reinforcing member 5. It is understood that the first reinforcing member 5 may form any angle, such as 30° or 45°, with respect to the extension line of the second reinforcing member 6. Preferably, the center line of the first reinforcing member 5 is the mid-perpendicular line of the second reinforcing member 6.

[0054] The second reinforcing member 6 may be located above the first reinforcing member 5, below the first reinforcing tube, or on the side plate 20, and will not be described in detail here.

[0055] Since the second embodiment and this embodiment correspond to each other, this embodiment can be implemented in cooperation with the second embodiment. Note that the technical details mentioned in the second embodiment are also valid in this embodiment, and the technical effects achievable in the second embodiment can also be achieved in this embodiment, so they will not be mentioned here to reduce redundancy. Correspondingly, the technical details described in this embodiment can also be applied to the second embodiment.

[0056] A third embodiment of the present invention relates to a container including at least one side panel of the first embodiment or one side panel of the second embodiment, or a container including both side panels of the first and second embodiments. A first panel 1 of the side panel faces outside the container, and a second panel 2 of the side panel faces inside the container 100. Within the container, the side panels are connected to adjacent side panels by interlocking structures 90.

[0057] 15, the container 100 includes a bottom plate 81, a pair of opposing long side plates 82, and a pair of opposing short side plates 83, and the long side plates 82 and the short side plates 83 are both connected to the bottom plate 81. Here, the pair of short side plates 83 may both be the side plates of the first embodiment described above, or both may be the side plates of the second embodiment described above, or one of the pair of short side plates 83 may be the side plate of the first embodiment described above, and the other is the side plate of the first embodiment described above.

[0058] In other embodiments, the long side panels 82 may all be the side panels of the first embodiment described above, or all be the side panels of the second embodiment described above, or one of a pair of long side panels 82 may be the side panel of the first embodiment described above, and the other may be the side panel of the first embodiment described above.

[0059] In other embodiments, each side panel of the container may be the same length, or the container may have fewer than four or more than four side panels.

[0060] While preferred embodiments of the present invention have been described in detail above, it should be understood that aspects of the embodiments can be modified, if necessary, to provide additional embodiments using aspects, features, and concepts from various patents, applications, and publications.

[0061] These and other changes can be made to the embodiments in light of the above detailed description. In general, in the claims, the terms used should not be considered limited to the specific embodiments disclosed in the description and claims, but should be understood to include all possible embodiments along with all equivalents to which these claims are entitled.
