Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging technology, and in particular to a packaging structure. Background Technology
[0002] To prevent damage to goods during transportation, various items need to be packaged before being shipped. The edges of the packaging structure are key areas that bear external pressure, and their mechanical properties directly affect the packaging's impact resistance and stacking stability.
[0003] Current packaging often relies on traditional bending and splicing processes to create sharp edges. For example, the corners of boxes are often formed by simple folding or seam bonding, leading to stress concentration in localized weak areas. Statistics show that approximately 30% of packaging damage during transportation originates from edge deformation or cracking, especially in heavy cargo transport scenarios where corner collapse rates can exceed 40%. To reduce the damage rate of packaged goods, it is currently necessary to improve the structural strength of packaging. Utility Model Content

[0008] Multiple corner protectors are respectively provided at multiple edges of the packaging, and the corner protectors are sandwiched between the packaging and the packaging box.
[0009] In one embodiment, each edge of the packaging is provided with a corner protector.
[0010] In one embodiment, the corner protector includes a first protector and a second protector that are bent and connected together, with an included angle between the first protector and the second protector, and the first protector and the second protector are respectively disposed on both sides of the edge of the packaging.
[0011] In one embodiment, the top support is configured as a flat plate structure, and the corner guards are provided at the periphery of the top support to form a first groove with the top support;
[0012] The corner protector has a clearance section at the upper end of the edge of the side panel, and the clearance section extends into the first groove.
[0013] In one embodiment, the side panel includes a first side panel and a second side panel disposed opposite to each other. The first side panel includes a first body and two first side panels extending from both ends of the first body toward the second side panel. The second side panel includes a second body and two second side panels extending from both ends of the second body toward the first side panel. There is a gap between the two first side panels and the two second side panels.
[0014] In one embodiment, both the first side plates and both second side plates are provided with abutting protrusions, which are used to abut against the packaged items.
[0015] In one embodiment, the heights of the plurality of abutting protrusions are equal; and / or
[0016] The height of the abutting protrusion is less than the height of the first side plate; and / or
[0017] The height of the abutting protrusion is less than the height of the second side plate.
[0018] In one embodiment, the base is configured as a flat plate structure, and the corner protectors are provided at the periphery of the base to form a second groove with the base, the second groove being used to place packaged items.

[0036] To prevent damage to goods during transportation, various items need to be packaged before being shipped. The edges of the packaging structure are key areas that bear external pressure, and their mechanical properties directly affect the packaging's impact resistance and stacking stability.
[0037] Current packaging often relies on traditional bending and splicing processes to create sharp edges. For example, the corners of boxes are often formed by simple folding or seam bonding, leading to stress concentration in localized weak areas. Statistics show that approximately 30% of packaging damage during transportation originates from edge deformation or cracking, especially in heavy cargo transport scenarios where corner collapse rates can exceed 40%. To reduce the damage rate of packaged goods, it is currently necessary to improve the structural strength of packaging.
[0038] This utility model proposes a packaging structure.
[0039] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the packaging structure includes a packaging box 100, a packaging component 200, and multiple corner protectors 300. The packaging component 200 includes a top support 210, a bottom support 220, and side panels 230, which together form a receiving space 201 to accommodate the packaged items 400. The multiple corner protectors 300 are respectively located at multiple edges of the packaging component 200 and are sandwiched between the packaging component 200 and the packaging box 100.
[0040] It is understandable that household appliances, construction equipment, and other items need to be packaged during logistics and transportation to prevent damage. Common household appliances include, but are not limited to, dishwashers, refrigerators, and washing machines. The packaged item 400 shown in the figures of this utility model is a built-in dishwasher.
[0041] In one embodiment, the packaging 200 includes a top support 210, a bottom support 220, and a side panel 230. The upper end of the side panel 230 is connected to the top support 210, and the lower end of the side panel 230 is connected to the bottom support 220. This allows the top support 210, bottom support 220, and side panel 230 to enclose a receiving space 201, within which the packaged item 400 is placed. Specifically, the packaged item 400 is placed on the bottom support 220, the top support 210 is placed on top of the packaged item 400, and the side panel 230 surrounds the sides of the packaged item 400, thus placing the packaging 200 outside the packaged item 400 for protection. By providing the packaging 200 with separate top support 210, bottom support 220, and side panel 230, the assembly of the packaging 200 is facilitated, improving the convenience of packaging the packaged item 400.
[0042] The packaging structure also includes a box 100, which is fitted over the package 200 to further enhance the protection of the packaged item 400. Understandably, in one embodiment, the box 100 has an open bottom and a foldable flap at the top. When packaging the item 400, the package 200 is placed over the item 400, and then the box 100 with its flap open is fitted over the package 200. The flap is then closed, and the base tray 220 and the box 100 are secured together with packing straps to complete the packaging of the item 400. Thus, when the packaging structure needs to be disassembled, the packing straps can be cut, and the box 100 can be removed directly from the top, avoiding the need to move the item 400 during unpacking and mitigating the inconvenience of moving a heavy item 400.
[0043] Understandably, packaging structures have edges, which are key areas for withstanding external pressure. To improve the support capacity at these edges, this invention provides corner protectors 300 on the outer side of the edges of the packaging component 200. Thus, on one hand, the corner protectors 300 enhance the support strength of the edges of the packaging component 200, improving its structural strength. The corner protectors 300 support both the inner edges of the packaging component 200 and the outer edges of the packaging box 100, thereby increasing the overall structural strength of the packaging structure. On the other hand, the corner protectors 300 fill the gap between the packaging component 200 and the packaging box 100, preventing relative movement between them and further enhancing the protection of the packaged goods 400.
[0044] It should be noted that the materials of the packaging box 100, the packaging component 200, and the multiple corner protectors 300 can be the same or different. The materials can be wood, plastic, or paper. No restrictions are placed on the specific materials of the packaging structure.
[0045] In an embodiment of this utility model, each edge of the packaging component 200 is provided with a corner protector 300.
[0046] Understandably, the top support 210, bottom support 220, and side panel 230 of the packaging 200 all have edge settings, and corner guards 300 are provided on the outer side of all the edges of the top support 210, bottom support 220, and side panel 230, thereby strengthening the structural strength of each edge of the packaging 200, ensuring the structural strength of the packaging structure, and improving the protection of the packaged items 400.
[0047] Please see Figure 3 In an embodiment of this utility model, the corner protector 300 includes a first protector 310 and a second protector 320 that are bent and connected. The first protector 310 and the second protector 320 have an included angle. The first protector 310 and the second protector 320 are respectively disposed on both sides of the edge of the packaging 200.
[0048] Specifically, in the embodiment shown in the figures of this utility model, the corner protector 300 includes a first protector 310 and a second protector 320 connected together, with an included angle between the first protector 310 and the second protector 320. It is understood that in packaging structures, edges are generally right-angled edges, and correspondingly, the included angle between the first protector 310 and the second protector 320 is approximately a right angle. That is, the corner protector 300 is configured with an "L"-shaped structure. Thus, compared to the irregular structures of the first protector 310 and / or the second protector 320, the design of this utility model makes the structure of the corner protector 300 simpler, thereby facilitating the processing of the corner protector 300. Of course, the included angle between the first protector 310 and the second protector 320 is consistent with the shape of the edges of the packaging component 200 to better fit the edges and provide better support.
[0049] In one embodiment, the width and thickness of the first protective element 310 and the second protective element 320 are equal. This facilitates the processing and forming of the corner protector 300 and improves the processing efficiency of the corner protector 300. Of course, in other embodiments, the width and thickness of the first protective element 310 and the second protective element 320 can also be different to accommodate packaging articles 400 with different structures.
[0050] In one embodiment, the first protective element 310 and the second protective element 320 have equal widths and thicknesses. In this case, the width of the first protective element 310 is 55-65 mm, and its thickness is 4-6 mm. This ensures that the corner protectors 300 provide sufficient support to the edges of the packaging 200 while avoiding excessive width and thickness, thus contributing to a lightweight and low-cost packaging structure.
[0051] Please see Figure 1 and Figure 2 In an embodiment of this utility model, the top support 210 is configured as a flat plate structure, and the corner guard 300 is provided on the periphery of the top support 210 to form a first groove (not shown) with the top support 210; the corner guard 300 is provided with a relief section 330 at the upper end of the edge of the side panel 230, and the relief section 330 extends into the first groove.
[0052] Understandably, the top support 210 is a flat plate structure, with corner protectors 300 located around its perimeter. In one embodiment, the flat plate structure of the top support 210 is configured as a rectangle, with a corner protector 300 located on each of the four sides of the rectangle. The first protective body 310 of each corner protector 300 is connected to the top of the top support 210, and the four second protective bodies 320 together with the top support 210 form a first groove with the opening facing downwards. Compared to a frame structure, the present invention uses a flat plate structure for the top support 210, which simplifies the structure of the top support 210, while the corner protectors 300 around the perimeter of the top support 210 ensure the structural strength of the top support 210.
[0053] Understandably, the side panel 230 has edges extending vertically, and each edge has a corner protector 300 on its outer side. That is, the corner protectors 300 extend vertically on the side panel 230. At the upper end of the edge of the side panel 230, the corner protector 300 has a clearance section 330. That is, the top of the corner protector 300 is lower than the top of the side panel 230. Thus, when the top support 210 covers the packaged article 400, the top of the packaged article 400 and a portion of the clearance section 330 of the side panel 230 both extend into the first groove, thereby achieving a snap-fit connection between the top support 210 and the side panel 230. In this way, the relative fixation of the side panel 230 and the top support 210 is achieved without using other connecting parts.
[0054] Please see Figure 1 and Figure 2 In an embodiment of this utility model, the side panel 230 includes a first side panel 231 and a second side panel 235 disposed opposite to each other. The first side panel 231 includes a first body 232 and two first side panels 233 extending from both ends of the first body 232 toward the second side panel 235. The second side panel 235 includes a second body 236 and two second side panels 237 extending from both ends of the second body 236 toward the first side panel 231. There is a gap between the two first side panels 233 and the two second side panels 237.
[0055] Understandably, in this invention, the side panels 230 are configured as a first side panel 231 and a second side panel 235, which facilitates packaging of the side panels 230 compared to the overall structure. When packaging the packaged item 400, a robotic arm can be used to push the first side panel 231 and the second side panel 235 into place from opposite sides of the packaged item 400, thereby achieving packaging of the side panels of the packaged item 400 and facilitating packaging automation.
[0056] Please see Figure 2In one embodiment, the first side panel 231 includes a first body 232 and two first side panels 233 extending from both ends of the first body 232 toward the second side panel 235. That is, one first side panel 233, the first body 232, and the other first side panel 233 are connected in sequence and form a roughly "U" shaped structure. The second side panel 235 includes a second body 236 and two second side panels 237 extending from both ends of the second body 236 toward the first side panel 231. That is, one second side panel 237, the second body 236, and the other second side panel 237 are connected in sequence and form a roughly "U" shaped structure. In this way, by setting the side panel 230 as two independent structural components, the front and rear sides and the left and right sides of the packaged item 400 can be packaged simultaneously. This facilitates automated packaging of the side panel 230 and avoids the need for multiple structural components in the side panel 230, thus simplifying the side panel 230.
[0057] Please see Figure 1 and Figure 2 In one embodiment, a first side panel 233 and a second side panel 237 are located on the same side of the packaged item 400, while another first side panel 233 and another second side panel 237 are located on the other side of the packaged item 400. A gap exists between the two first side panels 233 and the two second side panels 237. That is, after the first side panel 231 and the second side panel 235 package the packaged item 400, the first side panel 231 and the second side panel 235 do not contact each other, leaving a gap between them. This gap arrangement allows the first side panel 231 and the second side panel 235 to simultaneously package the front and back sides and left and right sides of the packaged item 400, while also saving on the number of side panels 230 required, which is beneficial for lightweighting and reducing the cost of the packaging structure. It is understood that the distance of the gap can be adjusted according to the size and weight of the packaged item 400, and no specific limit is imposed on the distance here.
[0058] Please see Figure 2 In an embodiment of this utility model, both first side plates 233 and both second side plates 237 are provided with abutting protrusions 234, which are used to abut against the packaged items 400.
[0059] For ease of explanation, the first body 232 and the second body 236 are defined to contact the left and right sides of the packaged item 400, and the two first side panels 233 and the two second side panels 237 are defined to contact the front and rear sides of the packaged item 400. It is understood that there are gaps between the two first side panels 233 and the two second side panels 237, meaning that the front and rear sides of the packaged item 400 are not fully enclosed. To ensure the structural strength of the side panels 230 for the front and rear sides of the packaged item 400, abutment protrusions are provided on the inner sides of the two first side panels 233 and the two second side panels 237. When the side panels 230 package the packaged item 400, the abutment protrusions contact and abut with the front and rear sides of the packaged item 400 respectively, thereby improving the supporting force of the side panels 230 for the front and rear sides of the packaged item 400.
[0060] In embodiments of this utility model, the heights of the plurality of abutting protrusions 234 are equal; and / or, the height of the abutting protrusions 234 is less than the height of the first side plate 233; and / or, the height of the abutting protrusions 234 is less than the height of the second side plate 237.
[0061] In one embodiment, the abutment protrusions on the two first side plates 233 and the two second side plates 237 are positioned at the same location, and the heights of the plurality of abutment protrusions 234 are equal. This facilitates the simplification of the structure of the first side plates 233 and the second side plates 237. In another embodiment, the first side plate 231 and the second side plate 235 have the same structure or are mirror images of each other. This facilitates the simplification of the structure of the side plate 230 and improves the processing efficiency of the side plate 230.
[0062] In one embodiment, the height of the abutment protrusion 234 is less than the height of the first side plate 233 and / or the second side plate 237. This ensures adequate protection for the front and rear sides of the packaged article 400 while also contributing to a lighter packaging structure. It is understood that the height of the abutment protrusion 234 can be set according to the structure, size, and weight of the packaged article 400, and no limitation is placed on the height of the abutment protrusion 234 here.
[0063] Please see Figure 2 In an embodiment of this utility model, the base tray 220 is configured as a flat plate structure, and the corner protectors 300 are provided on the periphery of the base tray 220 to form a second groove 221 with the base tray 220. The second groove 221 is used to place the packaged items 400.
[0064] Understandably, in one embodiment, the base support 220 and the top support 210 are configured the same, that is, the base support 220 is also configured as a flat plate structure, and the corner protectors 300 are provided at the periphery of the base support 220. In one embodiment, the flat plate structure of the base support 220 is configured as a rectangle, and a corner protector 300 is provided at each of the four sides of the rectangle. The first protective body 310 of each corner protector 300 is connected to the bottom of the base support 220, and the four second protective bodies 320 and the base support 220 together form a second groove 221 with the slot opening facing upward. Compared with the base support 220 being configured as a frame structure, the present invention sets the base support 220 as a flat plate structure, which is beneficial to the simplification of the structure of the base support 220, while the corner protectors 300 at the periphery of the base support 220 ensure the structural strength of the base support 220. The second groove 221 is used for placing the packaged item 400. Thus, the setting of the second groove 221 provides guidance for the installation and placement of the packaged item 400, and at the same time, the second groove 221 also provides a limit for the packaged item 400, preventing the packaged item 400 from shaking within the packaging structure.
[0065] Understandably, the side panel 230 has edges extending in the vertical direction, and each edge has a corner protector 300 on its outer side. That is, the corner protectors 300 extend vertically on the side panel 230. In one embodiment, the bottom end of the corner protector 300 is flush with the bottom end of the side panel 230. In one embodiment, the side panel 230 and the corner protectors 300 on the side panel 230 are in contact with the upper end face of the corner protectors 300 on the base support 220. That is, the bottom of the first side panel 231 and the bottom of the corner protectors 300 on the first side panel 231, the bottom of the second side panel 235 and the bottom of the corner protectors 300 on the second side panel 235 are all in contact with the upper end face of the corner protectors 300 on the base support 220. The corner protectors 300 on the base support 220 are used to support the side panel 230 and the corner protectors 300 on the side panel 230.
[0066] When packaging the packaged items 400, the corner protectors 300 are already installed on the edges of the top support 210, bottom support 220, and side panel 230. Thus, when packaging the packaged item 400, the packaged item 400 is first placed in the second groove 221 of the base tray 220, so that the packaged item 400 contacts the inner wall of the groove 221; then the first side panel 231 and the second side panel 235 are pushed in from opposite sides of the packaged item 400, so that the first side panel 231, the corner protectors 300 on the first side panel 231, the second side panel 235, and the corner protectors 300 on the second side panel 235 all contact the upper end face of the corner protectors 300 on the base tray 220; then the top tray 210 is placed on top of the packaged item 400, so that part of the packaged item 400 and the clearance section 330 of the side panel 230 extend into the first groove; then the packaging box 100 is placed over the packaged item 200 and the corner protectors 300 from top to bottom; finally, the packaging box 100 and the base tray 220 are tied together with packaging straps.
[0067] When it is necessary to unpack the packaged item 400, cut the packaging straps, remove the packaging box 100 from the top, then remove the top support 210 from the top, and then remove the first side panel 231 and the second side panel 235 from the opposite sides of the packaged item 400 to take out the packaged item 400.
[0068] In this way, the bottom of the first side panel 231 and the bottom of the corner protectors 300 on the first side panel 231, as well as the bottom of the second side panel 235 and the bottom of the corner protectors 300 on the second side panel 235, all come into contact with the upper surface of the corner protectors 300 on the base support 220, facilitating the packaging and disassembly of the packaging structure. It is worth noting that the corner protectors 300 on the base support 220 and the corner protectors 300 on the top support 210 are of different sizes at this time.
[0069] With increasing global environmental awareness, traditional packaging materials (such as plastics and foams) are gradually being phased out of the market due to their non-degradability, high energy consumption in production, and difficulties in recycling. Against this backdrop, paper packaging, with its renewable, easily degradable, and low environmental impact characteristics, has become an ideal alternative to traditional materials.
[0070] In this embodiment of the invention, the packaging box 100, the packaging component 200, and the multiple corner protectors 300 are all made of paper. The use of paper material contributes to the environmental friendliness of the packaging structure. The corner protectors 300 help improve the structural strength of the packaging structure.
[0071] In one embodiment, the packaging box 100 and the package 200 are configured with corrugated cardboard; the corner protectors 300 are configured with cardboard. Specifically, the cardboard for the corner protectors 300 is made by bonding and laminating packaging paper, and then processing it into a cardboard with a certain angle. In one embodiment, the outer layer of the corner protectors 300 is kraft paper, while the inner layer is not limited; the corner protectors 300 are edged with kraft paper. Thus, the corrugated cardboard ensures the cushioning and shock absorption function of the packaging structure, while the cardboard ensures the structural strength of the packaging structure. In one embodiment, the paper corner protectors 300 are glued to the outer edge of the package 200. This makes the connection between the corner protectors 300 and the package 200 more convenient.
[0072] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
