Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically to a self-heating hot pot packaging box. Background Technology

[0002] With the development of society and the economy, people's living standards have improved, and self-heating foods have been widely promoted and used. Self-heating foods allow for quick and easy consumption of hot food in any environment without any cooking or heating tools. With the development of self-heating food technology, self-heating hot pots have emerged. A self-heating food box mainly consists of an outer box, an inner box, and a lid. The inner box is placed inside the outer box, and the lid covers the opening of the outer box. There is space between the bottom of the inner box and the bottom of the outer box to hold the heating pack. The self-heating principle of the food box is that the heating pack is placed at the bottom of the outer box, and an appropriate amount of water is added. When the heating pack comes into contact with water, it releases heat, which is quickly added to the food inside the inner box. Self-heating food technology was once a military technology in China, mainly used in field mess kits. In recent years, it has become popular in China, with a wide variety of self-heating boxes and foods available, especially plastic ones. However, some self-heating boxes have poor structures, obstructed steam channels, resulting in poor heating performance and slow heating speed. Furthermore, the outer and inner boxes become too hot during heating, making them difficult to move and prone to burns. Therefore, a self-heating hot pot packaging box is needed.

The ring-locking groove part 201 is fixedly connected to the ring-locking part 101. A support column 4 is fixedly connected to the bottom of the box body 1, and a carrier box 3 is placed on the support column 4. The upper side of the carrier box 3 is in contact with the inner wall of the box body 1, and a protruding middle plate 10 is fixedly connected to the middle of the carrier box 3. A support block 8 and a bottom ring block 9 are fixedly connected to the bottom of the box body 1, and the bottom ring block 9 is placed at a distance from the bottom of the support column 4. Ear parts 5 are fixedly connected to both sides of the top of the box body 1, and an arc-shaped block 6 is fixedly connected to the top of the ear parts 5.

[0025] In this embodiment, positioning blocks 14 are fixedly connected to both sides of the middle of the inner wall of the box 1, and an overlapping edge 301 is provided above the bearing box 3, with the overlapping edge 301 positioned above the positioning blocks 14.

[0026] Furthermore, the carrier box 3 is provided with a first loading part 302 and a second loading part 303, and the first loading part 302 and the second loading part 303 are located on both sides of the raised middle plate 10.

[0027] Furthermore, a plurality of first reinforcing ribs 11 are fixedly connected to the upper part of the inner wall of the carrier box 3, and a plurality of second reinforcing ribs 12 are fixedly connected to the bottom of the carrier box 3.

[0028] A positioning block 14 is provided on the inner wall of the box body 1. The positioning block 14 can support the carrier box 3, so that the carrier box 3 is placed stably inside the box body 1. At the same time, the carrier box 3 is further supported by the support column 4 below. The first reinforcing rib 11 and the second reinforcing rib 12 are used to increase the overall strength of the carrier box 3.

[0029] In this embodiment, the support column 4 has a hollow portion 401 inside, and the bottom of the hollow portion 401 has an opening 402. The opening 402 is positioned within the bottom ring block 9 with a gap between them. By utilizing the opening 402 in the hollow portion 401 of the support column 4, the box body 1 becomes more resilient to shrinkage and expansion when heated internally.

[0030] In this embodiment, a thickened plate portion 203 is provided in the middle of the upper cover 2, and an annular groove portion 202 is formed between the edge of the thickened plate portion 203 and the edge of the upper cover 2.

[0031] Furthermore, a vent hole 7 is provided in the middle of the thickened plate portion 203, and the vent hole 7 is connected to the interior of the carrier box 3.

[0032] A thickened plate 203 is provided in the middle of the upper cover 2 to increase the sealing strength of the hot pot inside the carrier box 3. At the same time, the vent 7 on the thickened plate 203 can release hot air to prevent burns when opening the lid.

[0033] In this embodiment, an arc-shaped recess 13 is provided below the ear piece 5. The arc-shaped recess 13 below the ear piece 5 prevents the hot pot from slipping when holding the entire pot.

[0034] Working principle:

[0035] The ring-locking part 101 provided above the box body 1 cooperates with the ring-locking groove part 201 below the upper cover part 2, so that the upper cover part 2 is firmly covered on the box body 1. A support column 4 is provided at the bottom of the box body 1, and the overlapping edge part 301 of the carrier box 3 is placed on the positioning block 14 provided on both sides of the inner wall of the box body 1. In this way, the support column 4 and the positioning block 14 are stabilized inside the box body 1 by the carrier box 3. The carrier box 3 is divided into a first filling part 302 and a second filling part 303 by the protruding middle plate 10. The first filling part 302 and the second filling part 303 can be filled with different hot pot soup ingredients. At the same time, since there is a gap between the edge of the carrier box 3 and the inner wall of the box body 1, the heat in the carrier box 3 is transferred to the middle of the box body 1 more slowly, thereby reducing the heat of the middle wall of the box body 1.

[0036] In addition, the box body 1 contains self-heating material, but the box body 1 has ear parts 5 on both sides, and the ear parts 5 have arc-shaped blocks 6 and arc-shaped recesses 13 above and below them respectively. When a person needs to pick up the entire packaging box, they only need to hold the ear parts 5. At the same time, the arc-shaped blocks 6 and arc-shaped recesses 13 will prevent slipping when picking it up.
