Description

packaging structure

technical field

The invention relates to a packaging structure, in particular to an easily disassembled packaging structure and a buffer support device for loading display panels or other fragile items. the

Background technique

The packaging of fragile items has always been an important issue during product delivery. Insufficient packaging often results in damage to items during transportation, thereby increasing production costs. In particular, fragile items with special sizes and shapes, such as liquid crystal glass or display panels, are prone to stress concentration due to their special sizes and shapes, increasing the possibility of being damaged. the

Taking the transportation of display panels as an example, traditionally, when transporting display panels, it is usually necessary to add cushioning and supporting materials such as polystyrene in the shipping cartons to reduce the direct impact of external forces on the display panels. As shown in FIG. 1 , a traditional packaging structure includes an outer carton 10 , a middle carton 20 and a buffer support material 30 . The buffer support device material 30 is arranged in the middle carton 30 , and the outer carton 10 is covered outside the middle carton 20 and the buffer support device material 30 . After being boxed, the display panel 11 can be protected by the buffer support material 30 . However, in order to save the use of the cushioning and supporting device material 30 , the cushioning and supporting device material 30 is generally only used locally, rather than comprehensively covered. In the case of insufficient filling, the fixing between the buffer support material 30 and the middle carton 20 is more important. In order to effectively fix the buffer support device material 30 on the middle carton 20, glue is generally used as an adhesive for fixing. However, the adhered buffer support device material 30 and the middle layer carton 20 are not easy to disassemble, and require a large waste storage space after use. In addition, because it is not easy to disassemble, it takes a lot of labor and time to disassemble before it can be recycled, and even some joint parts cannot be disassembled and separated because they are too tightly combined, and the waste formed after use cannot be recycled, resulting in environmental protection. question. the

Another object of the present invention is to provide a packaging structure and its buffer support device, which have a reliable positioning effect of the buffer support device. the

Another object of the present invention is to provide a packaging structure and its buffer support device, which can save space for waste storage. the

Another object of the present invention is to provide a packaging structure and its buffer support device, which can reduce the possibility of dust and water entering. the

In order to achieve the above object, the present invention provides a packaging structure, which includes a box body and a buffer support device. The box body mainly includes a bottom plate and a side wall, wherein the side wall intersects with the bottom plate and forms an angle. The buffer support device is arranged on the bottom plate of the box body, and its two ends are in contact with the two side walls of the box body respectively. The buffer support device has a strip-shaped body and an elastic engaging component; the strip-shaped body has a side surface and an end surface connected to the side surface. The elastic engaging component has a connecting portion and an engaging portion, wherein the connecting portion is connected to the elongated body. When the engaging portion is at the first position, the engaging portion protrudes outside the side of the elongated body.

As shown in FIG. 3 , the side surfaces 311 are respectively located on the long sides of the elongated body 310 and distributed along the extending direction of the elongated body 310 . The end surface 313 is located on the short side of the elongated body 310 and is preferably perpendicular to the side surface 311 . the

Two ends of the elongated body 310 respectively abut against two sidewalls 230 of the box body 200 . In this embodiment, since the base plate 210 is a rectangle, the buffer support device 300 is a rectangle formed across the base plate 210 . The top of the buffer support device 300 is preferably formed with a plurality of positioning grooves 301 , and the positioning grooves 301 can provide a positioning function when the display panel or other items to be packed or transported are loaded. In a preferred embodiment, the buffer support device 300 is made of foamed polypropylene (FPP), but it can also be made of other organic resin or rubber materials. the

As shown in FIG. 3 , the elastic engaging component 330 has a connecting portion 331 and an engaging portion 333 , wherein the connecting portion 331 is connected to the elongated body 310 .

In other words, the elastic engaging component 330 straddles the end surface 313 of the elongated body 310 . However, in different embodiments, the elastic engaging component 330 may also only have a single engaging portion 333 , so it only protrudes from a single side 311 . When the engaging portion 333 is at the first position, the elastic engaging component 330 releases all the elastic potential energy, that is, no elastic potential energy generated by external force is accumulated in the elastic engaging component 330 . Therefore, the engaging portion 333 can be maintained at the first position without other external force. the

When combined with the box body 200 , the engaging portion 333 can be bent to the second position, as shown in FIG. 4 . At this time, the engaging portion 333 shrinks into the side surface 311 of the elongated body 310 and accumulates elastic potential energy due to the deformation of the elastic engaging component 330 . In this embodiment, the engaging portion 333 is bent to the bottom of the elongated body 310, but also maintained in the plane extending from the side 311 of the elongated body 310; in other words, the engaging portion 333 is bent to the second position, that is, it is located on the same side of the side surface 311 as the elongated body 310 . In a preferred embodiment, the engaging portion 333 is bent to the second position by an external force, and the engaging portion 333 is maintained at the second position by the external force. When the external force is removed, the engaging portion 333 will fully or partially return to the first position by rebounding through the accumulated elastic potential energy. the

As shown in FIG. 5 , the side wall 230 of the box body 200 has a plurality of lugs 231 and ear holes 233 . The ear holes 233 correspond to the lugs 231 ; in other words, the ear holes 233 are formed corresponding to the lugs 231 . As shown in FIG. 5 , the ear hole 233 is formed surrounded by the lug 231 . In this embodiment, the lug 231 is located at the connection position between the side wall 230 and the bottom plate 210 , that is, at the side of the bottom plate 210 ; In a preferred embodiment, the lug 231 is formed by: cutting parallel and spaced cutting lines 250 on the side wall 230 and the bottom plate 210 along the direction perpendicular to the edge of the bottom plate 210, as shown in FIG. 6; A portion in the middle of the wire 250 protrudes to form the lug 231 . However, in different embodiments, the lug 231 can also be adhered, nailed or otherwise formed on the side wall 230 or the bottom plate 210 . In addition, the shape of the lug 231 is not limited to the rectangle shown in FIG. 5 and FIG. 6 , but may be circular or other shapes. the
