[0024] 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.

[0025] 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.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] Reference Figures 1 to 5 As shown, this embodiment provides a paper tray packaging box, including a paper base frame 10, a paper tray 20, a supporting wall panel 30, and a supporting longitudinal beam 40. The base frame 10 is a square frame structure, and the paper tray 20 is also square and is placed inside the base frame 10. Specifically, the paper tray 20 is formed by connecting at least two groove units 201 sequentially along the length direction. In this embodiment, the number of groove units 201 is four, connected sequentially along the length direction. The groove units 201 are used to place product 1. The groove walls of two adjacent groove units 201 are spaced apart and connected at the top. The supporting wall panel 30 is embedded between the groove walls of two adjacent groove units 201. Specifically, two adjacent groove units 201 are connected only through the top of the groove wall to form a receiving cavity 21 with a bottom opening and a side opening. The number of supporting wall panels 30 is three, each embedded in one of the three receiving cavities 21, effectively supporting the groove walls of the groove units 201. All three receiving cavities 21 extend in the width direction, and the supporting wall panel 30 also extends in the width direction.

[0029] The four groove units 201 of the paper tray 20 and the bottom of the supporting wall panel 30 are recessed inward to form an elongated recess extending along the length direction. Specifically, the recess 22 at the bottom of the paper tray 20 and the notch 32 at the bottom of the supporting wall panel 30 together form a continuous elongated recess. Specifically, there are two elongated recesses arranged side-by-side; there are also two supporting longitudinal beams 40, each embedded in one of the two elongated recesses; the supporting wall panel 30 and the supporting longitudinal beams 40 are perpendicular to each other, forming a three-horizontal and two-vertical cross-support structure; this provides excellent support and fixation in both the length and width directions, providing stable support for the paper tray 20, making it less prone to deformation, and effectively enhancing its support performance. Thus, it is not necessary to increase the overall thickness of the paper tray 20 to strengthen its support strength.

[0030] Furthermore, the two ends of the supporting wall panel 30 extend out of the side openings of the receiving cavity 21 and are connected to baffles 31, resembling an "I" shape. The baffles 31 extend to the side ends of two adjacent groove units 201, making the installation of the supporting wall panel 30 and the paper tray 20 more precise and less prone to offset in the width direction. During its embedded installation, the supporting wall panel 30 is inserted from the bottom opening of the receiving cavity 21.

[0031] The supporting wall panel 30 is composed of multiple layers of cardboard stacked on top of each other to give the supporting wall panel 30 sufficient strength, while the baffle 31 can be obtained by bending two of the cardboard layers of the supporting wall panel 30 in the opposite direction, or it can be an independent cardboard that is adhered to the side of the supporting wall panel 30.

[0032] The supporting longitudinal beam 40 is a hollow rigid frame with a square cross-section, which can be obtained by folding a piece of cardboard. This structure saves materials and reduces weight while ensuring the strength of the supporting longitudinal beam 40.

[0033] The paper tray 20 has paper support plates 50 on both sides of its length direction. In this embodiment, the support plates 50 have a "U" shape structure, supporting the paper tray 20 on its side ends in the length direction and part of its side ends in the width direction, and providing effective support for the outer ends of the paper tray 20.

[0034] For the reinforcement design of the paper tray 20 itself, in this embodiment, the bottom of the groove unit 201 has protrusions 23 arranged in an array; the groove wall of the groove unit 201 has reinforcing ribs 24; thus, the strength of the paper tray 20 itself can be effectively strengthened.

[0035] Specifically, the bottom frame 10 is made of cardboard, and its surface is flat, mainly serving as a decorative element for the outer packaging.

[0036] Example 2

[0037] The paper tray packaging box provided in this embodiment has a structure that is largely the same as that disclosed in Embodiment 1, except that: (Refer to...) Figure 6 and Figure 7 As shown, this embodiment also includes a paper base 60, which is housed within the base frame 10. The base 60 has a receiving groove 61 adapted to the paper tray 20. That is, the base 60 does not have a structure with multiple groove units, but rather has only one receiving groove 61, similar to the base frame 10. The paper tray 20 is placed within the receiving groove 61 of the base 60. In other words, an additional layer of base 60 is added between the base frame 10 and the paper tray 20.

[0038] The supporting wall panel 30 is embedded between the groove walls of two adjacent groove units 201 of the paper tray 20, and together with the paper tray 20, is placed in the receiving groove 61 of the base tray 60. This forms a double-layered, double-tray structure. The bottoms of the base tray 60, at least two groove units 201 of the paper tray 20, and the supporting wall panel 30 are recessed inwards to form an elongated recess extending along the length direction; that is, the bottom of the base tray 60 is also recessed inwards, forming this elongated recess at the bottom of the base tray 60. The supporting longitudinal beam 40 is embedded within this elongated recess, that is, the supporting longitudinal beam 40 is embedded in the bottom of the base tray 60.

[0039] In this embodiment, the support plate 50 is also disposed on the outer end of the base 60.

[0040] Additionally, it includes paper support columns 70. Specifically, these support columns 70 are hollow cylindrical structures made of wound paper sheets, providing excellent support. The support columns 70 support the ends and side walls of the paper tray 20. Specifically, the support columns 70 supporting the side walls of the paper tray 20 are directly embedded in the support wall panel 30, forming a fixed structure with the support wall panel 30, making the assembly more reliable. Compared to the structure of Embodiment 1, the paper tray packaging box of this embodiment has stronger support strength.

[0041] The above two embodiments disclose the preferred solutions of this application. Of course, other embodiments are not limited to these. For example, the number of supporting longitudinal beams 40 can be one or more; the supporting wall panel 30 may not have a structure with baffle 31; or a supporting column 70 structure may also be provided in the single support structure of Embodiment 1; the supporting column 70 may also be provided only at the end or side wall of the paper tray 20, etc.

[0042] Specifically, all components of the paper tray packaging box in this application are made of paper.

[0043] 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.
