Description

Technical Field

[0001] This utility model relates to the technical field of flame-retardant foam packaging boxes, specifically a flame-retardant foam packaging box. Background Technology

[0002] Flame-retardant foam packaging boxes use lightweight foam core material as the base and are covered with flame-retardant composite film or metal foil on the outside, forming a multi-functional integrated structure that is heat-insulating, moisture-proof, cushioning, and fireproof. They are widely used in the long-distance transportation and warehousing of fragile, flammable, and temperature-sensitive goods. With the improvement of logistics safety levels, the industry has put forward comprehensive performance requirements for the boxes in terms of flame spread suppression, high-temperature dimensional maintenance, stacking strength, reusability, and environmental adaptability. However, traditional box types generally rely on adhesive bonding and rigid connections, resulting in insufficient impact resistance, non-adjustable internal cushioning, fixed air volume, poor handling ergonomics, and the entire box must be scrapped once partially damaged. This makes it difficult to meet the continuous upgrading needs of high-frequency turnover and diverse transportation scenarios, creating an urgent expectation for a purely mechanical linkage improvement solution.

[0003] Existing flame-retardant foam boxes have low rigidity and are prone to collapse. The inner liner is rigidly fixed without cushioning, making them easily damaged by impact. The ventilation holes are not adjustable, leading to uncontrolled temperature and humidity. The handles are detached from the bottom pad, making them inconvenient to handle. They are multi-layered and glued together, so they are scrapped if damaged. They also pose a high risk of flame-retardant dripping. Utility Model Content

[0004] The purpose of this invention is to provide a flame-retardant foam packaging box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A flame-retardant foam packaging box includes a box body, an outer shell on the upper part of the box body, an anti-slip pad fixedly connected to the bottom of the box body, a lid handle on the upper part of the outer shell, side handles fixedly connected to both sides of the outer side of the box body, and an inner liner inside the box body.

[0006] As a further embodiment of this utility model: the interior of the outer shell is connected by an adhesive material to form a heat insulation layer, a polystyrene foam board layer, a flame retardant layer, and a moisture-proof membrane.

[0007] As a further embodiment of this utility model, the inner liner is fixedly connected to the box body via a T-shaped connecting plate.

[0008] As a further embodiment of this utility model: the T-shaped connecting plate has internal threaded connecting bolts.

[0009] As a further embodiment of this utility model, an anti-slip pad is fixedly connected inside the inner liner.

[0010] As a further embodiment of this utility model: a lid handle is fixedly connected to the upper part of the outer shell, and a vent hole is provided on the upper part of the outer shell.

[0011] As a further embodiment of this invention, the anti-slip mat is made of TPE material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by locking the T-shaped connecting plate and the bolts with threads, the inner liner and the box body form a detachable rigid node, which not only improves the overall stacking strength, but also facilitates maintenance and replacement. The integrated bonding structure of heat insulation layer, flame retardant layer and moisture-proof film realizes multi-condition protection of a single box, reduces composite processes and reduces weight. The lid handle and side handle are symmetrically arranged, and with the bottom anti-slip pad, it can be gripped with one hand and stacked without slipping, improving handling efficiency. The ventilation holes are integrally molded with the outer shell, combined with TPE anti-slip pad cushioning, taking into account temperature and humidity balance and item positioning, and extending the transportation safety period.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 In this embodiment of the utility model, a flame-retardant foam packaging box includes a box body 1, an outer shell 2 is provided on the upper part of the box body 1, an anti-slip bottom pad 5 is fixedly connected to the bottom of the box body 1, a lid handle 4 is provided on the upper part of the outer shell 2, side handles 6 are fixedly connected to both sides of the outer side of the box body 1, and an inner liner 9 is provided inside the box body 1.

[0016] Preferably, the interior of the outer shell 2 is connected by an adhesive material to form a heat insulation layer 11, a polystyrene foam board layer 12, a flame retardant layer 13, and a moisture-proof membrane 14. The inner liner 9 is fixedly connected to the box body 1 by a T-shaped connecting plate 8. The T-shaped connecting plate 8 is internally connected to bolts 7. An anti-slip pad 10 is fixedly connected inside the inner liner 9. A lid handle 4 is fixedly connected to the upper part of the outer shell 2. A vent hole 3 is provided on the upper part of the outer shell 2. The anti-slip pad 10 is made of TPE material.

[0017] The working principle of this utility model is as follows: During use, the operator first grasps the lid handle 4 and applies upward force, causing the outer shell 2 to flip open around the hinge, completely opening the top of the box 1. Then, the packaged items are placed stably on the anti-slip mat 10 surface of the inner liner 9. Utilizing the micro-elastic deformation and high coefficient of friction of the TPE anti-slip mat 10, the items are cushioned and stored on the TPE anti-slip mat 10, preventing strong shaking during transportation. After the items are placed, the outer shell 2 is flipped downwards to reset its position, so that its sealing lips fit snugly against the upper edge of the box 1, forming a closed cavity. At this time, the anti-slip pad 5 at the bottom of the box 1 generates static friction with the surface of the transport vehicle or warehouse pallet, preventing displacement of the box 1 during acceleration, braking, or stacking. During transportation, the heat from the external environment is first blocked by the heat insulation layer 11 inside the outer shell 2, and then further reduced by the polystyrene foam board layer 12, thus maintaining a stable temperature in the inner liner 9. The flame-retardant layer 13 can quickly carbonize and isolate oxygen when exposed to open flames, inhibiting the spread of flames. The moisture-proof film 14 prevents moisture penetration, protecting the items from drying out. Vent 3 is located at the upper end of the outer shell 2. It can automatically adjust its opening degree according to the temperature difference between the inside and outside of the box 1 to maintain air pressure balance and prevent the box 1 from bulging or collapsing. If the inner liner 9 needs to be cleaned or replaced after transportation, simply use a tool to loosen the bolts 7 on the T-shaped connecting plate 8, remove the T-shaped connecting plate 8, and the inner liner 9 can be pulled out as a whole. The reverse operation can be used to quickly reset the box 1, enabling repeated use.

[0018] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
