AI Technical Summary
Existing antibacterial food containers do not have a scalding-proof structure when filled with hot food, and the internal space is not completely sealed, which can easily lead to hot food mixing with the food or cross-contamination of flavors.
The design incorporates a combination structure of an anti-scalding outer box and an inner box, with a sealing gasket layer at the step to achieve a seal and prevent direct hand contact with the inner box. Meanwhile, a snap ring and snap block structure ensures the lid's airtightness.
It achieves both heat protection and effective sealing of the food space, avoiding problems such as scalding hands and food mixing or cross-contamination of flavors.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of lunch boxes, specifically to an antibacterial plastic composite lunch box. Background Technology
[0002] Chinese utility model patent application number 202220643629.8 proposes an antibacterial split-type lunch box. It has a limiting groove and a limiting frame at the opening of the box body. When the box lid is pressed against the box body containing food, the flow-blocking frame is inserted into the limiting groove, and the bottom edge of the box lid is in contact with the limiting frame, achieving a double sealing effect. During the shaking process, soup and solid food are not easy to flow out, keeping the food inside the lunch box clean and hygienic, and has a good antibacterial effect.
[0003] However, it still has some shortcomings: First, the outer surface of the box is not equipped with a heat-proof structure, which makes it easy to burn your hands when filling it with hot food. Second, although the inside of the box is equipped with multiple spaces for placing food, these spaces are not sealed after the lid is closed. The top of the partition and the bottom surface of the lid do not have a sealing effect, which makes the food inside easily mix or have cross-contamination of flavors under the action of external force.
[0004] Accordingly, this utility model proposes an antibacterial plastic composite lunch box to solve the above problems. Utility Model Content
[0005] To overcome the shortcomings of the prior art, this utility model provides an antibacterial plastic composite lunch box. By setting an anti-scalding outer box, the inner box into which food is directly filled is separated, and the hand will not directly touch the inner box, thereby achieving an anti-scalding effect. At the same time, the sealing gasket can be squeezed to the upper end of the step and the partition, thereby sealing each food storage space and preventing food from mixing or odors from mixing.
[0006] Technical solution
[0007] An antibacterial plastic composite lunch box includes an inner box body, the inner box body having several partitions inside, the partitions separating multiple food storage spaces, the top of each food storage space having a step flush with the top of the partition, a lid being fitted onto the upper side of the step, and an anti-scalding outer box body being provided on the outer side of the inner box body.
[0008] Furthermore, the lower surface of the box cover is provided with a protrusion that matches the stepped portion, and the side of the protrusion near the inner box body is provided with a sealing gasket layer that can be pressed against the upper end of the stepped portion and the partition.
[0009] Furthermore, the four sides and bottom surface of the heat-resistant outer box are provided with several evenly distributed anti-slip ribs.
[0010] Furthermore, the inner wall of the heat-resistant outer box is fixed to the outer surface of the inner box by a number of connecting posts, and the top of the heat-resistant outer box is fixedly connected to the top of the inner box.
[0011] Furthermore, a retaining ring is provided on the upper surface of the inner box, and a groove ring that can cooperate with the retaining ring is provided on the lower surface of the box cover.
[0012] Furthermore, the outer heat-resistant box has locking blocks on its left and right side walls, and the lid is hinged with a buckle. The buckle is fastened to the lower part of the locking blocks and presses the lid against the inner box and the outer heat-resistant box.
[0013] Beneficial effects
[0014] Compared with the prior art, this utility model has the following advantages:
[0015] By setting up a heat-resistant outer box, the inner box that directly contains food is separated, preventing hands from directly touching the inner box and thus achieving a heat-resistant effect; at the same time, the sealing gasket can be squeezed onto the upper part of the step and the partition, thereby sealing each food storage space and preventing food from mixing or odors from mixing.

[0019] To better illustrate the content of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments:
[0020] have Figure 1 As shown, this utility model discloses an antibacterial plastic composite lunch box, including an inner box body 1. The inner box body is provided with a plurality of partitions 2, which separate multiple food storage spaces 5. The top of each food storage space 5 is provided with a step portion 14 that is flush with the top of the partition 2. A box cover 7 is installed on the upper side of the step portion 14. The outer side of the inner box body 1 is provided with an anti-scalding outer box body 3.
[0021] Furthermore, the lower surface of the box cover 7 is provided with a protrusion 8 that is adapted to the step portion 14, and a sealing gasket layer 9 that can be pressed against the step portion 14 and the upper end of the partition 2 is provided on the side of the protrusion 8 near the inner box body 1.
[0022] Furthermore, the four sides and bottom surface of the heat-resistant outer box 3 are provided with a number of evenly distributed anti-slip ribs 13.
[0023] Furthermore, the inner wall of the heat-resistant outer box 3 is fixed to the outer surface of the inner box 1 by a number of connecting posts 4, and the top of the heat-resistant outer box 3 is fixedly connected to the top of the inner box 1.
[0024] Furthermore, a retaining ring 6 is provided on the upper surface of the inner box 1, and a grooved ring 10 that can cooperate with the retaining ring 6 is provided on the lower surface of the box cover 7.
[0025] Furthermore, the left and right side walls of the heat-resistant outer box 3 are provided with locking blocks 12, and the lid 7 is hinged with a buckle 11. The buckle 11 is fastened to the lower part of the locking blocks 12 and presses the lid 7 against the inner box 1 and the heat-resistant outer box 3.
[0026] Specifically, by setting up an anti-scalding outer box 3, the inner box 1, which is directly filled with food, is separated, so that the hand will not directly touch the inner box 1, thereby achieving anti-scalding;
[0027] At the same time, the sealing gasket 9 can be pressed against the upper end of the step portion 14 and the partition 2, thereby sealing each food storage space 5 and preventing food from mixing or odors from mixing.
[0028] The presence of the retaining ring 6 enables the guidance and positioning of the lid 7;
[0029] The presence of anti-slip ridges 3 increases the friction between the hand and the heat-resistant outer shell 3, preventing inconvenience in gripping due to oil stains.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the technical solutions of this utility model have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
