Description

Technical Field

[0001] This utility model relates to the field of goods packaging and transportation, specifically to an inner liner and packaging pallet mechanism for packaging. Background Technology

[0002] With increasing environmental awareness, biodegradable materials are being widely used. In the field of goods packaging and transportation, biodegradable foamed plastic materials are often used to prepare inner linings for carrying goods, offering advantages such as good cushioning and environmental friendliness. However, they also have significant drawbacks, namely, weak inherent support capacity; they cannot provide support when multiple layers are stacked. Therefore, in existing technologies, a sufficiently thick surrounding plate is usually installed around the inner lining to support the objects above; this increases the overall weight, and consequently, material and transportation costs. Utility Model Content

[0003] To address these issues, this invention provides an inner liner and packaging tray mechanism for packaging.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A packaging liner includes a liner body made of biodegradable foamed plastic material, wherein a receiving groove is formed on the liner body; and vertically arranged paper support columns are embedded in the groove wall of the liner body.

[0006] Furthermore, the support column penetrates the upper and lower surfaces of the inner liner body and is flush with them.

[0007] Furthermore, the inner liner body has an outer edge groove wall located at the outer edge position to form a receiving groove, and vertically arranged paper support columns are embedded in the outer edge groove wall at the end corner positions of the inner liner body.

[0008] Furthermore, the inner liner body has multiple receiving grooves, and the inner liner body also has a transverse groove wall and a longitudinal groove wall located on the inner side of the outer groove wall; the outer groove wall, the transverse groove wall and the longitudinal groove wall together enclose multiple receiving grooves, and the inner liner body also has vertically arranged paper support columns embedded at the intersection of the transverse groove wall and the longitudinal groove wall.

[0009] Furthermore, the inner liner body is directly fitted into the support column through a foaming process.

[0010] Furthermore, the inner liner body has mounting holes, and the support column is inserted into the mounting holes.

[0011] Furthermore, the support column is a tubular structure with a certain wall thickness or a solid column structure.

[0012] Furthermore, the material of the inner lining body is EPS foam or EPP foam.

[0013] A packaging pallet mechanism includes a pallet, a side panel, an inner liner, and a top cover. The inner liner is the packaging liner described above. The inner liner has a receiving groove for placing items. The inner liner is placed on the pallet. The side panel covers the outer perimeter of the inner liner. The top cover covers the inner liner and the side panel.

[0014] Furthermore, there are multiple inner lining pads, which are stacked sequentially from bottom to top.

[0015] The technical solution provided by this utility model has the following beneficial effects:

[0016] The inner liner body has vertically arranged paper support columns embedded in the wall of the receiving groove to strengthen the support of the inner liner. This reduces the thickness of the surrounding panel and lightens the overall weight. Furthermore, the paper support columns are low-cost and biodegradable, which not only conforms to the concept of environmental protection but also greatly reduces transportation costs.

[0021] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] In the description of this invention, terms such as "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0024] Reference Figures 1 to 4 As shown, this embodiment provides a packaging liner, comprising a liner body 10 made of biodegradable foamed plastic material and paper support columns 20. In this embodiment, the liner body 10 is prepared by foaming EPS (expandable polystyrene) foam material or EPP (expanded polypropylene) foam material. A receiving groove 11 is formed on the liner body 10; the receiving groove 11 is used to place items (such as batteries). The support columns 20 are embedded in the groove wall of the receiving groove 11.

[0025] Reference Figure 1 As shown, there are six receiving slots 11. The inner liner body 10 has an outer edge slot wall 12 located at the outer edge position and a transverse slot wall 13 and two longitudinal slot walls 14 located on the inner side of the outer edge slot wall 12. The outer edge slot wall 12, the transverse slot wall 13 and the longitudinal slot wall 14 together enclose six receiving slots 11. The inner liner body 10 has vertically arranged paper support columns 20 embedded on the outer edge slot wall 12 at the four corner positions, and two vertically arranged paper support columns 20 are also embedded at the intersection of the transverse slot wall 13 and the longitudinal slot wall 14, forming a relatively uniform support.

[0026] This embodiment also provides a packaging pallet mechanism, including a pallet, a side panel, an inner liner, and a top cover. The inner liner is the packaging inner liner described above. The inner liner is placed on the pallet. Specifically, in this embodiment, there are two inner liners, which are stacked one on top of the other. The side panel covers the outer perimeter of the inner liner, and the top cover covers the inner liner and the side panel.

[0027] The inner liner uses paper support columns 20 to enhance its support function. For example, in two stacked inner liners, the lower liner is supported by the embedded support columns 20, thus supporting the upper liner and the top cover. Simultaneously, if a packaging pallet mechanism or other object is stacked on top of the top cover, the inner liner of the lower packaging pallet mechanism can also effectively support the object above. This eliminates the need for a supporting panel (or reduces the support level of the panel), allowing for a reduction in panel thickness and overall weight. Furthermore, the paper support columns are low-cost and biodegradable, which not only aligns with environmental protection principles but also significantly reduces transportation costs.

[0028] The inner liner body 10 has mounting holes 15. The support column 20 is inserted into the mounting hole 15 by assembly. Specifically, the mounting hole 15 is vertically continuous, and the support column 20 penetrates both the upper and lower surfaces of the inner liner body 10 and is flush with them. That is, the upper end face of the support column 20 is flush with the upper surface of the inner liner body 10, and the lower end face of the support column 20 is flush with the lower surface of the inner liner body 10, thus achieving good support. Meanwhile, the support column 20 is a tubular structure with a certain wall thickness. For example, in this specific embodiment, the diameter of the mounting hole 15 is 4.2 cm; the outer diameter of the tubular support column 20 is 4.2 cm, achieving a tight fit with the mounting hole 15; its inner diameter is 2.5 cm, and the sufficient wall thickness ensures the support capacity of the support column 20.

[0029] The above discloses one of the preferred solutions of this application. Of course, in other embodiments, the inner liner body 10 can also be made of other biodegradable foamed plastic materials. The positions where the support columns 20 are embedded in the inner liner body 10 can be multiple sets spaced along the extension direction of the outer groove wall 12, or multiple sets spaced along the extension direction of the middle transverse groove wall 13 or longitudinal groove wall 14, etc.; or the inner liner body 10 can be directly embedded with the support columns 20 through a foaming process, without the need for subsequent assembly operations, and the combination is firm; or the support columns 20 can be solid column structures, etc.

[0030] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
