Description

Technical Field

[0001] This utility model belongs to the field of foam box technology, and in particular relates to a foam box for food packaging that is easy to stack. Background Technology

[0002] Food packaging foam boxes are typically made from plastic raw materials such as polystyrene and foaming agents. During the manufacturing process, these raw materials are heated and foamed to form a plastic structure with countless tiny pores inside. This structure gives foam boxes their lightweight, shockproof, and heat-insulating properties.

[0003] However, while existing food packaging foam boxes excel in lightweight, shock absorption, and insulation, their inconvenience in stacking is a significant drawback in practical use. Due to the properties of the foam material, it's difficult to ensure a tight seal between the boxes, leading to wobbling and even collapse when stacked. This not only increases the difficulty of warehousing and transportation but also raises the risk of breakage. Especially during peak logistics periods, large quantities of food packaging foam boxes need to be stacked efficiently and systematically for rapid sorting and distribution; the inconvenient stacking design becomes a key factor limiting efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a food packaging foam box that is easy to stack, in order to solve the problem that due to the characteristics of foam materials, the gaps between boxes are difficult to fit tightly, which makes them easy to shake or even collapse when stacked. This not only increases the difficulty of storage and transportation, but also increases the risk of damage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a food packaging foam box that is easy to stack, comprising a box body with a plurality of downwardly extending loading slots thereon, a reinforcing partition between the loading slots, the reinforcing partitions extending outwards and respectively connected to the inner walls of the box body, and a downwardly extending positioning slot in the middle of the reinforcing partition, wherein when the boxes are stacked on top of each other, the loading slot of the upper box body abuts against the loading slot of the lower box body.

[0006] As a further description of the above technical solution:

[0007] The depth of the positioning groove is less than the depth of the loading groove.

[0008] As a further description of the above technical solution:

[0009] The box extends outward from its periphery to form a limiting edge, and a limiting groove is provided at the bottom of the limiting edge. When the boxes are stacked on top of each other, the limiting groove of the upper box abuts against the limiting edge of the lower box.

[0010] As a further description of the above technical solution:

[0011] The loading slot is provided with an upwardly recessed limiting protrusion, which forms a limiting groove at the bottom of the loading slot. The upper and lower boxes are stacked by abutting against the limiting protrusion through the limiting groove.

[0012] As a further description of the above technical solution:

[0013] Several reinforcing ribs are provided between the reinforcing partition and the limiting edge.

[0014] As a further description of the above technical solution:

[0015] When the boxes are stacked on top of each other, the positioning groove of the upper box abuts against the positioning groove of the lower box.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] 1. In this utility model, several downwardly extending loading slots are provided inside the box body, with reinforcing partitions between the loading slots. Positioning slots are provided within the reinforcing partitions, with the depth of the positioning slots being less than the depth of the loading slots. Simultaneously, limiting edges are provided on the periphery of the box body, and limiting protrusions are recessed upwards at the bottom of the loading slots. When stacking is required, the bottom positions of the upper and lower boxes are abutted against the loading slots of the lower box body through the loading slots of the upper box body. Furthermore, the limiting groove at the bottom of the upper loading slot abuts against the limiting protrusion in the lower loading slot. The middle section abuts against the lower positioning slot through the upper positioning groove, and the top abuts against the limiting edge on the periphery of the lower box body through the limiting groove on the periphery of the upper box body. This structure ensures that the top, middle, and bottom are all positioned during stacking, greatly improving the stability and tightness of the stack, preventing easy shaking or even collapse during stacking, and facilitating efficient and orderly stacking and storage.

[0018] 2. In this utility model, by setting reinforcing ribs between the reinforcing partition and the box body, the stability of the box body is improved, and the probability of damage during transportation is avoided. Attached Figure Description

[0031] Please see Figure 1-3 This utility model provides a technical solution: a food packaging foam box that is easy to stack, including a box body 1, which is provided with a plurality of downwardly extending loading slots 2. Reinforcing partitions 3 are provided between the loading slots 2. The reinforcing partitions 3 extend to the periphery and are respectively connected to the inner walls of the four sides of the box body 1. A downwardly extending positioning groove 4 is provided in the middle of the reinforcing partition 3. When the box bodies 1 are stacked on each other, the loading slot 2 of the upper box body 1 abuts against the loading slot 2 of the lower box body 1.

[0032] The depth of the positioning groove 4 is less than the depth of the loading groove 2. Together with the loading groove and the limiting edge, it serves to limit the top, middle and bottom of the box, ensuring the tightness and stability of the box stacking.

[0033] The box body 1 extends outward from its periphery to form a limiting edge 5. A limiting groove 6 is provided at the bottom of the limiting edge 5. When the box bodies 1 are stacked on top of each other, the limiting groove 6 of the upper box body 1 abuts against the limiting edge 5 of the lower box body 1.

[0034] The loading groove 2 is provided with an upwardly recessed limiting protrusion 7, and the limiting protrusion 7 forms a limiting groove 8 at the bottom of the loading groove 2. The upper and lower box bodies 1 are stacked by abutting against the limiting protrusion 7 through the limiting groove 8.

[0035] Several reinforcing ribs 9 are provided between the reinforcing partition 3 and the limiting edge 5. This improves the stability of the box and reduces the probability of damage during transportation.

[0036] When the boxes 1 are stacked on top of each other, the positioning groove 4 of the upper box 1 abuts against the positioning groove 4 of the lower box 1.

[0037] Working principle: Several downward-extending loading slots are set inside the box, with reinforcing partitions between them. Positioning slots are set within the reinforcing partitions, with a depth less than that of the loading slots. These are complemented by limiting edges on the periphery of the box and upward-recessed limiting protrusions at the bottom of the loading slots. When stacking is required, the bottom of the upper and lower boxes abut against the loading slot of the lower box through the loading slot of the upper box, and the limiting groove at the bottom of the upper loading slot abuts against the limiting protrusion in the lower loading slot. The middle section abuts against the lower positioning slot through the upper positioning slot, and the top abuts against the limiting edge on the periphery of the lower box through the limiting groove on the periphery of the upper box. This structure ensures that the top, middle, and bottom are all limited during stacking, greatly improving the stability and tightness of the stack, preventing easy shaking or even collapse, and facilitating efficient and orderly stacking and storage.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
