Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, specifically a cardboard box suitable for freezing. Background Technology

[0002] In the field of frozen logistics and storage, cardboard boxes serve as crucial packaging containers, their performance directly impacting the quality and transportation efficiency of frozen goods. With the rapid development of the frozen industry, the requirements for frozen cardboard boxes are also increasing. While existing frozen cardboard box technology meets basic needs to a certain extent, it still has many shortcomings that urgently need improvement. Current moisture-proofing measures for frozen cardboard boxes are relatively simple, mostly relying on simple coatings or the inherent properties of the material itself. In a frozen environment, moisture easily penetrates the box, causing goods to become damp and deteriorate. Furthermore, during handling and frozen storage, goods are susceptible to vibration and impact. Utility Model Content

[0003] The purpose of this invention is to provide a cardboard box suitable for freezing, so as to solve the problem of insufficient moisture-proof performance of existing frozen cardboard boxes mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A cardboard box suitable for freezing includes a box body with an open top for freezing and a box lid installed at the four edges of the top of the box body. A moisture-proof base is provided at the bottom of the box body. The moisture-proof base is integrally formed with the box body. Hand supports are installed in the middle of the top outer walls on both sides of the box body. The box body includes a corrugated cardboard core, the outer wall surface of the corrugated cardboard core is provided with a low-temperature resistant kraft paper shell, and the inner wall of the corrugated cardboard core is provided with a moisture-proof coating.

[0005] Preferably, the moisture-proof coating is a waterproof wax coating or a polyethylene film with a thickness of 0.05-0.1 mm, which allows an effective and uniform moisture barrier to be formed inside the box. The waterproof wax coating or polyethylene film has good waterproof performance, preventing external moisture from penetrating the box and protecting frozen items from moisture. The thickness of 0.05-0.1 mm ensures the moisture-proof effect without increasing the cost and weight of the cardboard box due to excessive thickness, achieving a good balance between moisture protection, economy, and portability.

[0006] Preferably, the low-temperature resistant kraft outer shell and the outer wall of the corrugated cardboard inner core are bonded and fixed together by a low-temperature adhesive layer. The low-temperature adhesive layer is a polyvinyl acetate layer or a hot melt adhesive layer. The polyvinyl acetate layer or hot melt adhesive layer still has good adhesion under low-temperature conditions and will not delaminate due to temperature drop, ensuring a tight bond between the low-temperature resistant kraft outer shell and the corrugated cardboard inner core. This enhances the stability of the overall structure of the box in the freezing environment and effectively resists the adverse effects of low temperature.

[0007] Preferably, the moisture-proof base includes an acrylic base plate and a foam shock-absorbing layer disposed at the bottom of the box. The acrylic base plate is rigid and provides stable support for the box, preventing the box from directly contacting the ground and becoming damp. The foam shock-absorbing layer effectively buffers external vibrations and impacts, reducing damage to the items inside the box during handling or freezing. The combination of the two improves the protection performance of the cardboard box for frozen items from both moisture-proof and shock-absorbing perspectives.

[0008] Preferably, the thickness of the foam shock-absorbing layer is 0.5-3cm, which can reasonably control costs and carton space while ensuring shock absorption effect. This thickness range can be adjusted according to the weight and fragility of different frozen items, effectively absorbing vibration energy without making the foam shock-absorbing layer too thick, thus avoiding taking up too much space inside the box or increasing costs excessively.

[0009] Preferably, corner protectors are installed at the four corners where the box body connects to the acrylic base plate, effectively protecting the corners of the box body. During handling, stacking, or use, the corners of the box body are easily subjected to collisions and wear. The corner protectors can buffer and protect the corners, prevent damage, extend the service life of the carton, and reduce the risk of structural damage to the box body due to corner damage.

[0010] Preferably, the handle includes a plastic inner core and a rubber anti-slip sleeve disposed on the surface of the plastic inner core. The plastic inner core provides a basic support structure, and the rubber anti-slip sleeve increases the friction between the hand and the handle. When handling cartons, the hand is less likely to slip, improving the safety and stability of handling.

[0011] Preferably, the bottom surface of the plastic inner core has a groove for easy finger insertion, allowing fingers to be inserted more comfortably and securely into the support during handling. The groove design conforms to ergonomic principles, making it easier for the handler to exert force, reducing handling fatigue, and further improving the convenience and comfort of handling the cardboard box.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: This cardboard box, suitable for freezing, features an open top and four lids at the top edges, facilitating easy opening and closing and convenient storage and retrieval of items. An integrally formed moisture-proof base prevents ground moisture from entering the box, protecting the contents. Handles on the top outer walls of both sides facilitate handling. A low-temperature resistant kraft paper shell on the inner wall of the corrugated cardboard core enhances the box's low-temperature resistance, making it suitable for freezing environments. A moisture-proof coating on the inner wall of the corrugated cardboard core further prevents moisture absorption, ensuring the quality of the contents. Attached Figure Description
