Description

Technical Field

[0001] This utility model relates to the field of frozen food packaging technology, specifically a composite frozen food packaging. Background Technology

[0002] Frozen food packaging refers to packaging methods using specific materials and processes to preserve frozen foods, ensuring their quality, hygiene, and safety, while also facilitating transportation, sales, and consumer use. Frozen food packaging must meet a range of requirements to maintain the stability of food in its frozen state and extend its shelf life.

[0003] In existing frozen food packaging, frozen food and ice packs are usually placed together in a foam box and then sealed with tape. This packaging method has some shortcomings:

[0004] 1. Foam boxes are difficult to lift and carry, making them inconvenient to transport;

[0005] 2. It is not easy to print patterns or text on the outside of the foam box, resulting in poor aesthetics;

[0006] 3. Ice packs inevitably produce condensation. If frozen food is placed with ice packs, the condensation may contaminate the frozen food.

[0007] Therefore, this case arose. Utility Model Content

[0026] This utility model embodiment provides a composite frozen food packaging, such as... Figure 1-4 As shown, the device includes a box body 1 and a box cap 2. Frozen food is placed inside the box body 1 and is packaged using vacuum sealing. The box cap 2 covers the top of the box body 1. A set of fixing grooves 3 are formed on the upper end of the inner sidewalls on both sides of the box cap 2. These fixing grooves 3 are horizontally arranged and oriented opposite each other along the length of the inner sidewalls of the box cap 2. An elastic frame 4 is held within each of the fixing grooves 3. The elastic frame 4 can be integrally molded, preferably made of metal or plastic. The elastic frame 4 includes a bottom surface 41, two side wings 42, and fixing strips 43. The two side wings 42 are located on both sides of the bottom surface 41. The side wing 42 is inclined inward to the bottom surface 41, so that the bottom surface 41 has a certain elasticity. The fixing strip 43 is horizontally set on the upper end of the side wing 42. Several through holes 44 are arranged on the bottom surface 41. An ice pack 5 is placed on the bottom surface 41. A raised platform 6 is set in the center of the bottom surface 41 of the box body 1. The raised platform 6 is surrounded by slopes 7. The elastic frame 4 is also subject to certain size restrictions. For example, in terms of height, it should not exceed the internal depth of the box cap 2, and the bottom surface 41 is smaller than the inner top surface of the box cap 2. This leaves space for fingers to reach into both sides of the side wing 42 when disassembling or installing the elastic frame 4.

[0027] Example 1, as Figure 1 and 2 As shown, the combination of box 1 and box cap 2 in the technical solution is for storing frozen food for carrying or transportation. However, box 1 and box cap themselves have no handles, making them inconvenient to carry. Therefore, an outer packaging is proposed. The outer packaging includes a lower box 8, which is fitted and wrapped around the outside of box 1, providing a second layer of packaging and protection for the frozen food. Simultaneously, the outer surface of the outer packaging can be used to print various patterns or slogans for product promotion, enhancing its aesthetics. Furthermore, handles 9 can be provided on both sides of the lower box 8. These handles are flexible, such as... Figure 1 As shown, the handles 9 on both sides surround the upper part of the box cap 2 from bottom to top. The handles 9 are provided with handle holes 10, through which goods can be lifted.

[0028] In the above embodiment one, as Figure 1 and 2As shown, in order to further fix the lifting belt and thus fix the box cap 2 and the box body 1, a locking hole 11 is provided on one side of the handle belt 9, and a buckle 12 is provided on the corresponding other side of the handle belt 9. The buckle 12 is detachably connected in the locking hole 11. As shown in the figure, the buckle 12 can be set on the belt, and the buckle 12 is connected to the locking hole 11 by the belt passing over the upper end.

[0029] In embodiment 2, the upper opening of the box body 1 is provided with a rim 13, and the upper opening of the lower box body 8 is located at the lower end of the rim 13. A sealing groove 14 is provided inside the rim 13, and a sealing ring 15 is provided at the lower end of the opening of the corresponding box cap 2. When the box cap 2 is closed on the upper end of the box body 1, the sealing ring 15 is adapted to the sealing groove 14. The setting of the sealing ring 15 and the sealing groove 14 greatly improves the sealing performance of the internal space of the box body 1, reduces the hot and cold convection in the internal space of the box body 1, and prolongs the freezing preservation effect.

[0030] For other aspects, commonly used packaging materials can be used. For example, the box body 1 and the box cap are made of foam material, which provides good sealing and insulation. Insulation film is also adhered to the inner walls of the box body 1 and the box cap. The lower box body 8 is made of high-strength corrugated cardboard.

[0031] Working principle: When used in composite frozen food packaging, such as Figure 2 As shown, frozen food is placed inside the box 1, ice packs 5 are placed on the elastic frame 4, and the elastic frame 4 is then installed on the box cap 2. This separates the frozen food and ice packs 5, allowing for independent installation. Specifically, by pressing down on the two side wings 42 of the elastic frame 4, the fixing strips 43 of the elastic frame 4 are slid into the fixing grooves 3 of the box cap 2. Due to the principle of cold air moving downwards, the cold air from the ice packs 5 on the elastic frame 4 will be conducted downwards to the frozen food through the through holes 44 on the bottom surface 41 of the elastic frame 4, creating a preservation environment. Then, the opening of the box cap 2 is closed. The sealing ring 15 at the lower end is aligned with the sealing groove 14 at the upper end of the opening of the box 1, and the sealing cover is closed. Then, the handles 9 on both sides of the lower box 8 are opened to the sides, and the box 1 is placed into the lower box 8. Then, the handles 9 on both sides are overlapped from bottom to top, and the buckle 12 on one side of the handle 9 is fastened into the buckle hole 11 on the other side of the handle 9, so as to fix the two handles 9 on both sides. This also fixes the position of the box cap 2 and the box 1. When it is necessary to lift, it can be taken out through the handle hole 10. When it is necessary to take out the frozen food, the direction can be operated.

[0032] In summary, this composite frozen food packaging achieves independent installation of the ice pack 5 and the frozen food by placing the ice pack 5 on the elastic frame 4, which is clamped in the fixing groove 3 of the box cap 2, while the frozen food is placed inside the box body 1. Based on the principle of cold air sinking, the cold air from the ice pack 5 on the elastic frame 4 will be conducted downward to the frozen food through the through hole 44 on the bottom surface 41 of the elastic frame 4, forming a preservation environment. Furthermore, the ice pack 5 inevitably produces condensation, and the design of the raised platform 6 in the center of the bottom of the box body 1 and the surrounding slope 7 can cause the condensation to flow away from the raised platform 6, reducing the impact of condensation on the frozen food.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
