Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box technology, specifically to a reinforced moisture-proof corrugated cardboard box for quick-frozen foods. Background Technology

[0002] In recent years, with the improvement of people's living standards and the acceleration of the pace of life, the consumption of low-temperature preserved products, aquatic products, and frozen foods has been increasing. As the main tool for transporting frozen foods, corrugated cardboard boxes can cause condensation during storage and transportation due to temperature differences. When the ice on the surface of frozen foods is heated, it melts, and the melted water seeps into the interior of the corrugated cardboard box, reducing its structural strength and causing it to soften and break, thus affecting transportation. At the same time, corrugated cardboard boxes themselves have poor rigidity and are easily damaged by external impacts. To solve the above problems, there is a need for a reinforced moisture-proof corrugated cardboard box for frozen foods.

[0003] Existing corrugated cardboard boxes for frozen foods cannot effectively isolate and protect the frozen food inside during handling. This allows moisture from the melting of the frozen food to seep into the corrugated cardboard box, causing it to soften and break. Furthermore, the boxes lack moisture-proof performance and fail to provide adequate external protection. During storage and transportation, they are easily damaged by external impacts, leading to spoilage of the frozen food inside. Therefore, there is an urgent need for an enhanced moisture-proof corrugated cardboard box for frozen foods. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an enhanced moisture-proof corrugated cardboard box for frozen foods, in order to solve the problems of existing corrugated cardboard boxes for frozen foods that cannot isolate and protect the frozen foods inside, causing the moisture from the melting of the frozen foods to seep into the corrugated cardboard box, resulting in softening and damage to the corrugated cardboard box, poor moisture-proof performance, inability to provide safety protection for the exterior of the corrugated cardboard box, and easy damage to the outer wall of the corrugated cardboard box during storage and transportation, leading to spoilage of the frozen foods inside.

[0013] 1. This utility model, through the design of a box body, thermal insulation partitions, storage compartments, positioning plates, and sealing plates, utilizes environmentally friendly foamed materials for its thermal insulation partitions. These materials are recyclable, impact-resistant, and resistant to repeated freezing, effectively isolating and insulating frozen foods inside the box to prevent rapid thawing. Multiple storage compartments allow for categorized storage of frozen foods, preventing cross-contamination of odors or contamination of other products by thawed liquids. Furthermore, the multiple thermal insulation partitions are interlocked via positioning plates, forming a sealed space that enhances insulation and prevents thawed liquids from seeping into the box, thus improving its moisture-proof properties.

[0014] 2. This utility model uses a protective sleeve, reinforcing ribs, limiting rods, anti-slip grooves, a cover plate, a fixing shaft, and a fixing sleeve to bond the inner wall of the protective sleeve to the outer wall of the box, providing safety protection for the outer wall of the box and preventing direct impact from external forces on the surface of the box, which could cause damage. At the same time, the reinforcing ribs can improve its structural strength and enhance the safety performance during transportation. After the frozen food is assembled, the cover plate is fitted onto the protective sleeve and fixed by the fixing sleeve and the limiting rod. The connection is highly stable and facilitates the storage and retrieval of the frozen food inside, making it more practical. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] Please see Figures 1-5 A reinforced moisture-proof corrugated cardboard box for quick-frozen foods includes a box body 1. An insulation partition 2 is installed on the inner wall of the box body 1. Several storage compartments 3 are formed on the inner wall of the insulation partition 2. Positioning plates 4 are installed on the top of each storage compartment 3. A sealing plate 5 is installed on the top of the uppermost positioning plate 4. The insulation partition 2 is movably connected to the inner wall of the box body 1. The storage compartments 3 are evenly spaced around the central axis of the insulation partition 2. The bottom of each storage compartment 3 has a slotted design. The bottom of the sealing plate 5 engages with the top of the positioning plate 4. The box body 1, insulation partition 2, storage compartments 3, positioning plate 4, and sealing plate 5 are interconnected. The sealing plate 5 and the insulation isolation plate 2 are made of environmentally friendly foam material, which has the advantages of being recyclable, impact-resistant, and resistant to repeated freezing. They can effectively isolate and insulate the frozen food inside the box 1, preventing the frozen food from melting quickly. At the same time, the setting of multiple storage compartments 3 can classify and store frozen food, avoiding cross-contamination of odors or contamination of other products by molten liquid. Furthermore, multiple insulation isolation plates 2 are connected by positioning plates 4 to form a closed space inside, which improves the insulation effect and prevents the liquid from molten frozen food from seeping into the box 1, thereby improving the moisture-proof effect inside the box 1.

[0024] Please see Figures 1-5A reinforced moisture-proof corrugated cardboard box for quick-frozen foods is provided. The outer wall of the box body 1 is fitted with a protective sleeve 6. Several reinforcing ribs 7 are installed on the side walls of the protective sleeve 6. Limiting rods 8 are installed on the outer side walls of the protective sleeve 6. Anti-slip grooves 9 are provided at the bottom of the protective sleeve 6. A cover plate 10 is installed on the top of the protective sleeve 6. A fixing shaft 11 is installed on the outer wall of the cover plate 10. A fixing sleeve 12 is installed on the outer wall of the fixing shaft 11. The protective sleeve 6 is bonded to the box body 1. The reinforcing ribs 7 are arranged in a rectangular array centered on the central axis of the protective sleeve 6. The cover plate 10 is sleeved with the protective sleeve 6. The fixing sleeve 12 forms a rotating structure with the protective sleeve 6 via the fixing shaft 11. The fixing sleeve 12 is elastic. The protective sleeve 6 is attached to the outer wall of the box 1 by means of the protective sleeve 6, the reinforcing rib 7, the limiting rod 8, the anti-slip groove 9, the cover plate 10, the fixing shaft 11, and the fixing sleeve 12. This provides safety protection for the outer wall of the box 1 and prevents external forces from directly impacting the surface of the box 1, thus avoiding damage to the surface of the box 1. At the same time, the reinforcing rib 7 can improve its structural strength and improve the safety performance of transportation. After the frozen food is assembled, the cover plate 10 is fitted onto the protective sleeve 6 and fixed by the fixing sleeve 12 fitted onto the limiting rod 8. The connection is highly stable and facilitates the storage and retrieval of the frozen food inside, making it more practical.

[0025] Working principle: In use, first, place the insulation isolation panel 2 inside the box 1, then put the frozen food into the storage compartment 3, then place a new insulation isolation panel 2 on top of the insulation isolation panel 2 filled with frozen food, and secure it with the positioning plate 4. Finally, seal the top insulation isolation panel 2 with the sealing plate 5. The insulation isolation panel 2 is made of environmentally friendly foam material, which has the advantages of being recyclable, impact-resistant, and resistant to repeated freezing. It can effectively insulate and keep the frozen food inside the box 1 warm, preventing the frozen food from melting quickly. At the same time, the setting of multiple storage compartments 3 can classify and store frozen food, avoiding cross-contamination of odors or contamination of other products by thawed liquid. The multiple insulation isolation panels 2 are connected by the positioning plate 4, forming an internal seal. The enclosed space enhances insulation, preventing liquid from seeping into the box 1 after the frozen food thaws, thus improving the moisture-proof effect inside the box 1. The inner wall of the protective sleeve 6 is then bonded to the outer wall of the box 1, providing safety protection and preventing direct impact from external forces that could damage the surface of the box 1. The reinforcing ribs 7 also improve structural strength and transportation safety. After the frozen food is assembled, the cover plate 10 is fitted onto the protective sleeve 6 and secured with the limiting rod 8 via the fixing clip 12, ensuring high connection stability and facilitating the storage and retrieval of the frozen food. Finally, the entire assembly is loaded and transported, completing the device's operation. Any content not described in detail in this manual is prior art known to those skilled in the art.
