Abstract
Description
Technical Field
[0001] The utility model belongs to the field of disposable lunch boxes, in particular to a self-heating and degradable disposable lunch box. Background Art
[0002] Disposable fast food boxes have shifted from foam lunch boxes to environmentally friendly lunch boxes. The original foam lunch boxes have been eliminated because they are not resistant to high temperatures and the production process causes damage to the environment. They have been replaced by paper lunch boxes, wooden lunch boxes and other easy-to-degrade lunch boxes. In order to make it easier for people to eat meals at a more suitable temperature in cold seasons, some disposable lunch boxes now have self-heating functions.
[0003] Most of the existing self-heating disposable lunch boxes heat the bottom of the lunch box directly, but the temperature of the heating bag is usually high to ensure the heating effect. When heating and keeping warm some fresh foods, the high temperature will affect the taste of the food.
[0004] Therefore, we propose a self-heating biodegradable disposable lunch box to solve the above problems. Utility Model Content
[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a self-heating biodegradable disposable lunch box, which solves the problem that directly heating the lower part of the lunch box affects the taste of some food.
[0006] The technical solution adopted by the utility model is as follows: the self-heating biodegradable disposable lunch box proposed by the utility model includes a lunch box body, a heating box, a connecting plate and a cover plate, one end of the connecting plate is rotatably connected to the outside of the lunch box body, and the other end of the connecting plate is rotatably connected to the outside of the heating box, the upper part of the heating box is set as a heating groove, and a heating pack is arranged inside the heating groove.
[0007] Furthermore, the lower part of the lunch box body is arranged as a lunch box bottom plate, and the interior of the lunch box body is arranged as a lunch box containing groove.
[0008] Furthermore, a supporting bottom plate is fixedly connected to the lower portion of the heating box, and the inner diameters of the heating groove and the supporting bottom plate are the same as the outer diameter of the lunch box body.
[0009] Furthermore, the upper part of the cover plate is set as an upper cover groove, and the lower part of the cover plate is set as a lower cover groove. The inner diameter of the upper cover groove is the same as the outer diameter of the heating box, and the inner diameter of the lower cover groove is the same as the outer diameter of the lunch box body.
[0010] Furthermore, the lunch box body, the heating box and the cover plate are all made of waterproof paper material.
[0011] The beneficial effects achieved by the utility model using the above structure are as follows:
[0012] The self-heating biodegradable disposable lunch box proposed in this scheme is connected by rotating the lunch box body and the heating box, and a cover plate is provided for insulation and shielding. The lower part of the lunch box body can be directly heated to ensure the heating speed, and the rotating connecting plate can embed the heating box on the upper part of the lunch box body, and the food in the lunch box holding slot can be heated and kept warm through air heat transfer on the upper part, so as to avoid excessive temperature affecting the taste of fresh food.

[0020] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation to the present invention. DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0022] like Figure 1 , Figure 2As shown, the utility model proposes a self-heating biodegradable disposable lunch box, including a lunch box body 1, a heating box 2, a connecting plate 3 and a cover plate 4, one end of the connecting plate 3 is rotatably connected to the outside of the lunch box body 1, and the other end of the connecting plate 3 is rotatably connected to the outside of the heating box 2, the upper part of the heating box 2 is set as a heating groove 201, and a heating pack 202 is arranged inside the heating groove 201, the lower part of the lunch box body 1 is set as a lunch box bottom plate 101, and the interior of the lunch box body 1 is set as a lunch box holding groove 102.
[0023] like Figure 2 and 3 As shown, a supporting bottom plate 203 is fixedly connected to the lower portion of the heating box 2, and the inner diameters of the heating groove 201 and the supporting bottom plate 203 are the same as the outer diameter of the lunch box body 1. When the heating pack 202 is heating, the lower portion of the heating groove 201 is isolated from the desktop to prevent the high temperature of the heating pack 202 from scalding the desktop.
[0024] like Figure 1 and 2 As shown, the upper portion of the cover plate 4 is set as an upper cover groove 401, and the lower portion of the cover plate 4 is set as a lower cover groove 402.
