Abstract
Description
Technical Field
[0001] This utility model relates to the field of lunch boxes, specifically a pressed and molded environmentally friendly lunch box. Background Technology
[0002] With the fast pace of life, and especially the popularity of boxed fast food, its market spans the globe. However, the white pollution caused by discarded plastic fast food containers has severely damaged the ecological environment and constitutes a public nuisance. Although paper lunch boxes are recyclable and avoid pollution, existing paper lunch boxes contain additives and residual chemicals from the production process, making them environmentally unfriendly. Furthermore, the edges of these boxes are thin and lack rigidity, affecting their usability. Therefore, those skilled in the art have provided a press-molded environmentally friendly lunch box to solve the problems mentioned in the background section. Utility Model Content
[0003] The purpose of this utility model is to provide a pressed and molded environmentally friendly lunch box to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] An environmentally friendly pressed lunch box includes multiple lunch box sides, lunch box edges, corner folding thickened parts, lunch box bottom, and lunch box flat corner parts. The lunch box edges include edge thickened parts and corner thickened parts. The edge thickened parts further include edge folding gaps and edge folding parts. The corner thickened parts further include corner folding parts and corner folding gaps.
[0006] As a further embodiment of this utility model: the side portion of the lunch box and the flat corner portion of the lunch box are alternately arranged on the bottom edge of the lunch box, and the corner folding thickened portion is arranged in the area between the side portion of the lunch box and the flat corner portion of the lunch box.
[0007] As a further embodiment of this utility model: the corner thickening part is formed on the top of the corner folding thickening part and the flat corner of the lunch box, and the edge thickening part is integrally formed on the top of the side of the lunch box.
[0008] As a further embodiment of this utility model: the edge folding portion is formed at the end of the edge thickening portion, and the edge thickening portion has edge folding gaps at both ends of the edge folding portion.
[0009] As a further improvement of this utility model: the thickened corner portion is integrally formed at the end of the corner folding portion, and multiple corner folding gaps are provided on the corner folding portion.
[0010] As a further improvement of this utility model: the lunch box is made of pure paper folded and pressed, and both sides of the lunch box are coated with a cold-sealing adhesive layer or a heat-sealing adhesive layer.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention can be quickly produced by applying a sealing layer to pure paper and then selecting either cold or hot pressing folding to form the shape, depending on whether cold or hot sealing adhesive is applied. This ensures that the folded parts fit more firmly and are less prone to cracking. Moreover, it is made of pure paper, making it more environmentally friendly. The edges of the lunch box have folded sections, which can effectively increase the strength of the edges and improve durability. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-3 In this embodiment of the utility model, an environmentally friendly lunch box is provided by compression molding. The environmentally friendly lunch box includes multiple lunch box side portions 1, lunch box edge portions 2, corner folding thickened portions 3, lunch box bottom portions 4, and lunch box flat corner portions 5. The lunch box edge portion 2 includes an edge thickened portion 201 and a corner thickened portion 202. The edge thickened portion 201 further includes an edge folding gap 2011 and an edge folding portion 2012. The corner thickened portion 202 further includes a corner folding portion 2021 and a corner folding gap 2022.
[0019] The lunch box is made of pure paper folded and pressed, and both sides of the lunch box are coated with a cold-sealing adhesive layer or a heat-sealing adhesive layer.
[0020] By adopting the above technical solution, after applying a sealing layer to pure paper, cold pressing and folding can be selected according to the type of cold or hot sealing adhesive applied, which can quickly produce the product. This ensures that the folded parts are more firmly attached and less prone to cracking. Moreover, it is made of pure paper, which is more environmentally friendly. The edge 2 of the lunch box has a folded part, which can effectively increase the strength of the edge of the lunch box and improve its durability.
[0021] The side portion 1 and the flat corner portion 5 of the lunch box are alternately arranged on the edge of the bottom 4 of the lunch box, and the corner folding thickened portion 3 is arranged in the area between the side portion 1 and the flat corner portion 5 of the lunch box. The corner thickened portion 202 is formed on the top of the corner folding thickened portion 3 and the flat corner portion 5 of the lunch box, and the edge thickened portion 201 is integrally formed on the top of the side portion 1 of the lunch box.
[0022] The edge folding portion 2012 is formed at the end of the edge thickening portion 201, and the edge thickening portion 201 has edge folding gaps 2011 at both ends of the edge folding portion 2012, which can ensure that the edge folding portion 2012 can be folded smoothly.
[0023] The thickened corner portion 202 is integrally formed at the end of the corner folding portion 2021, and multiple corner folding gaps 2022 are provided on the corner folding portion 2021 to ensure that the corner folding portion 2021 can be folded smoothly.
[0024] The working principle of this utility model is as follows: During folding and forming, a cold-press folding or hot-press folding mold is selected according to the applied cold-sealing adhesive or hot-sealing adhesive. Then, the folding is performed along the fold lines between the corner thickened part 3, the bottom of the lunch box 4, the flat corner part 5 of the lunch box, and the side part 1 of the lunch box. During folding, it is ensured that the folded part is folded to the outside of the lunch box. Then, the edge folding part 2012 and the corner folding part 2021 are folded and placed into the mold for pressing and folding. The hot-sealing adhesive layer or cold-sealing adhesive layer can ensure that the folded parts are more firmly attached and less prone to cracking. Moreover, it is made of pure paper, which is more environmentally friendly. The edge part 2 of the lunch box has a folded part, which can effectively increase the strength of the edge of the lunch box and improve its durability.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
