Description

[0001] This application claims priority to Taiwan Patent Application No. 114132776, filed on August 27, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to articles used for warehousing, handling, or storage, and more particularly to a pallet structure for carrying packaging boxes such as containers. Background Technology

[0003] Existing pallets used to carry packaging boxes or containers can often be stored by stacking them one on top of another after use to reduce the space occupied. In order to further reduce the height space occupied and increase the number of pallets that can be stacked, existing pallets can also be partially nested on top of each other when stacked, so that the thickness of each additional layer is reduced, thereby achieving the aforementioned goal of reducing the height space occupied.

[0004] However, regardless of how the pallets are stacked, existing pallets will inevitably become skewed after each stacking due to factors such as tolerances or inaccurate alignment. Furthermore, once the bottom layer is stacked, the skewness accumulates with each subsequent layer, leading to increasing instability and even making it difficult to separate the bottom pallets due to prolonged pressure from gravity caused by the accumulated weight.

[0005] In view of this, in order to improve and solve the above-mentioned deficiencies, the applicant has devoted himself to research and applied theoretical principles, and finally proposed a design that is reasonable and effective in improving the above-mentioned deficiencies. Utility Model Content

[0006] The main objective of this application is to provide a tray structure in which each edge of the tray is provided with an interference structure that interacts with each other when stacked, so as to ensure effective alignment when stacked and prevent misalignment, and to limit the spacing between each other when stacked to prevent problems such as difficulty in separation caused by excessive fit due to weight pressure.

[0007] To achieve the above objectives, this application provides a tray structure, including four side frames and an inner structure. The four side frames are interconnected to form a frame-like structure, and each side frame has a top, an outer side extending downward from the outer edge of the top, and an inner side extending downward from the inner edge of the top. The inner structure is connected to each side frame, and the lower edge of the outer side of each side frame extends downward and is located below the bottom surface of the inner structure. Each side frame is provided with at least one interference notch, and each interference notch is formed by a partial recess of the outer side of the outer side into the top, and has a first interference wall and two second interference walls. The first interference wall is arranged in an outwardly inclined manner from the top part, and the two second interference walls are respectively located on both sides of the first interference wall and are arranged at a distance from each other, and are gradually inclined from top to bottom. Thus, when stacked, the interference notch of the upper tray structure extends to the interference notch of the lower tray structure and interferes with each other.

[0008] Furthermore, each frame has one or more height limiting structures at its top bottom, connecting the top, outer side and inner side.

[0009] Furthermore, the lower edge of the height-limiting structure is located above the internal structure.

[0010] Furthermore, the height restriction structure is in the form of a vertical sheet.

[0011] Furthermore, the outer sides of each frame are inclined or vertical.

[0012] Furthermore, the lower edge of the outer side of each frame extends outward, and the lower edge of the first interference wall also extends outward as a first interference edge, and the lower edges of the two second interference walls also extend outward as second interference edges. The first interference edge is connected to the two second interference edges respectively, and the two second interference edges are connected to the outer edge of the outer side and are integrally formed.

[0013] Furthermore, each frame has a recessed and conical alignment portion at the top surface where they are connected, and the bottom surface of the alignment portion has a mating alignment surface.

[0014] Furthermore, each alignment part is provided with a limiting structure on both sides, and a corresponding structure that matches the limiting structure is provided on both sides of the alignment surface.

[0015] Furthermore, at least one grip portion is provided on any frame, the grip portion having a force-bearing wall integrally extended from the top surface, and two support walls formed outward from the outer side to support the force-bearing wall to form a notch.

[0016] Furthermore, the internal structure may have one or more rib-like parts.

[0017] Furthermore, the internal structure is plate-shaped.

[0018] Furthermore, the internal structure also has multiple supporting ribs located below the plate-like structure. Attached Figure Description

[0062] To further disclose the features and technical content of this application, please refer to the following detailed description and accompanying drawings. However, the accompanying drawings are for reference and illustration only and are not intended to limit this application.

[0063] Please see Figure 1 and Figure 2 The figures shown are a perspective view of the first embodiment of this application and a perspective view of the first embodiment of this application. This application provides a tray structure T, including four side frames 1 and an inner structure 2. The side frames 1 are connected to each other to form a frame-like structure, and the inner structure 2 is connected to each side frame 1 or the frame-like structure and can be integrally formed. In the first embodiment of this application, the inner structure 2 can be in the form of one or more ribs to connect between any two opposite side frames 1, so as to form a plurality of open areas 20 in the frame-like structure, and the inner structure 2 can be interlaced when it is in the form of a plurality of ribs (figure not shown).

[0064] Please refer to the following: Figures 3 to 5 As shown, each tray structure T can be stacked vertically, and at least one interference notch 3 is provided on any side 1 of each tray structure T. Specifically, as... Figure 5 and Figure 6 As shown, each frame 1 has a top 10, an outer side 11 extending downward from the outer edge of the top 10, and an inner side 12 extending downward from the inner edge of the top 10. The inner side 12 can extend horizontally inward to form an inner edge 120, which can be used to connect each frame 1 to each other on the inner side with the inner edge 120 to increase the strength of the frame structure. At the same time, the inner structure 2 can be connected in the form of ribs to form an integral shape. Furthermore, one or more height limiting structures 10a can be provided below the top 10. The height limiting structure 10a can be in the form of a vertical plate and connected between the top 10, the outer side 11, and the inner side 12. In this way, on the one hand, the frame 1 can be provided as a structural reinforcement, and on the other hand, the height limiting structure 10a can limit the relative height of each tray structure T when stacked, and can prevent problems such as excessive stacking.

[0065] As described above, in the first embodiment of this application, the outer portion 11 may be inclined outwards and has an outer surface 110 and an inner surface 111. Furthermore, an outer edge 11a may extend horizontally outwards from the lower edge of the outer portion 11, which can increase stability when placed flat on the ground. Additionally, as... Figure 6As shown, the aforementioned internal structure 2 is horizontally connected between any two opposing frame edges 1. Specifically, it is horizontally connected to the inner side 12 of each frame edge 1, forming a horizontal imaginary line L on the bottom surface of the internal structure 2. The outer edge 11a of the outer side 11 (i.e., the lower edge of the outer side 11) is below or below the imaginary line L, allowing the inner side 111 of the outer side 11 to gradually slide into alignment with the outer side 110 of the outer side 11 of the lower tray structure T when the tray structures T are stacked, thus achieving a preliminary positioning effect during stacking. Furthermore, in this embodiment, the lower edge of the aforementioned height limiting structure 10a is above or above the imaginary line L. When the tray structures T are stacked, the height limiting structure 10a can precisely abut against the top surface 100 of the top 10 of the lower tray structure T, thereby further reducing the overall height or thickness of the tray structures T when stacked.

[0066] Please refer to the following as well. Figure 1 , Figure 2 and Figure 7 As shown, this application mainly involves forming one or more interference gaps 3 on each of the aforementioned frame borders 1 by partially recessing the outer side surface 110 of the outer portion 11 into the top 10. Each interference gap 3 contains a first interference wall 30 and two second interference walls 31. The first interference wall 30 is arranged outward from top to bottom within a portion of the top 10, while the two second interference walls 31 are located on both sides of the first interference wall 30 and are arranged at a distance from each other, gradually tapering downward from top to bottom. Furthermore, the lower edge of the first interference wall 30 can extend outward horizontally to form a first interference edge 30a, and the lower edges of the two second interference walls 31 can also extend outward horizontally to form second interference edges 31a. The first interference edge 30a is connected to the two second interference edges 31a, and the two second interference edges 31a are connected to the outer edge 11a of the outer portion 11 to form an integral continuous structure. Since the first interference wall 30 and the two second interference walls 31 face different directions, any interference gap 3 on each frame 1 can control at least the positive direction of the first orientation (such as the positive or negative direction of the X-axis) and the bidirectional direction of the second orientation (such as the positive and negative directions of the Y-axis). The interference gap 3 on the opposite frame 1 can control the opposite direction of the first orientation (i.e., the negative or positive direction of the X-axis) due to the first interference wall 30. Therefore, the pallet structure T can generate four different directions, such as the positive and negative directions of the first orientation and the positive and negative directions of the second orientation, by means of the mutual arrangement of the equal interference gaps 3 when stacked. This ensures that the four sides of the frame 1 are effectively aligned in four directions when stacked and are not easily tilted. After stacking, it can still maintain a vertically upright position. This not only makes it more stable on the stack and less prone to tipping over, but also makes the arrangement in the warehouse more neat and beautiful.

[0067] Please see again Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, at the connection points of the aforementioned frame 1, a concave and conical alignment portion 112 is provided downward from the interconnected top surface 100. The bottom surface of the alignment portion 112 has an alignment surface 113, which allows the alignment surface 113 to roughly mate with the alignment portion 112 of the lower tray structure T for easy stacking. Furthermore, limiting structures 13 can be provided on both sides of the alignment portion 112. The limiting structure 13 can also be in the form of a cubic pyramid prism, and corresponding structures 130 that cooperate with the limiting structure 13 are provided on both sides of the alignment surface 113, so as to further limit the movement after stacking and positioning.

[0068] Furthermore, this application may further provide at least one gripping part 4 on any of the frame 1 of each of the above-mentioned pallet structures T. The gripping part 4 has a force-bearing wall 40 integrally extended from the top surface 100, and two support walls 41 formed outward from the outer side 11 to support the force-bearing wall 40, so as to form a notch 42 for a person to apply force from bottom to top to hold, thereby facilitating the handling of the pallet structure T.

[0069] Therefore, the tray structure of this application can be obtained by using the above-described structure.

[0070] Furthermore, such as Figure 8 and Figure 9 The figures shown are a perspective view of the second embodiment of this application from one angle and a perspective view from another angle. The tray structure T differs primarily in the shape of its four side frames 1 and internal structure 2, with the internal structure 2 being flat to fill the space within each of the side frames 1, thus providing better structural strength. This demonstrates that this application is applicable to tray structures T designed in various different configurations.

[0071] And such Figure 10 and 11 As shown, in this embodiment, each of the tray structures T can still be stacked vertically. Wherein, as... Figure 12 and Figure 13 As shown, the outer side 11 of each of the frame 1 can be vertically oriented outwards. However, in this embodiment, the height space cannot be reduced as much as in the above embodiments when stacked. Furthermore, the inner structure 2 also has multiple support ribs 21 located below it (i.e., as shown below). Figure 9As shown), the equal support rib 21 can extend downward to be flush with or level with the lower edge of the height limiting structure 10a. At this time, the bottom surface of the inner structure 2 is based on the point where the equal support rib 21 or the lower edge of the height limiting structure 10a is flush with or level with the lower edge. That is, the equal support rib 21 or the lower edge of the height limiting structure 10a forms the above-mentioned horizontal imaginary line L. The equal support rib 21 makes each of the tray structures T abut against the top surface 100 of the top 10 of the lower tray structure T when they are stacked together with the height limiting structure 10a.

[0072] Finally, as Figure 12 and Figure 14 As shown, although this embodiment cannot reduce the height as described above, the first interference wall 30 of each interference gap 3 is still arranged in an outward tilt from top to bottom within the top 10. The two second interference walls 31 are respectively located on both sides of the first interference wall 30 and are arranged with a relative distance between them, and are gradually tilted from top to bottom. Therefore, the outer edge 11a of the outer part 11 (i.e., the lower edge of the outer part 11) is lower than or located below the bottom surface of the inner part 2. In other words, even if the lower edge of the first interference wall 30 extends downward and exceeds the bottom surface of the inner part 2, or even below the imaginary line L (i.e., where the lower edge of the equal support rib 21 or the lower edge of the height limiting structure 10a is cut off or level with it), the same effect as in the first embodiment can be achieved.

[0073] However, the above description is only a preferred embodiment of this application and does not limit the patent scope of this application. Therefore, all equivalent structural changes made using the content of this application's specification and drawings are also included within the scope of this application and are hereby stated.
