Description

Technical Field

[0001] The utility model relates to the field of degradable environmental protection lunch boxes, and particularly relates to a starch-based degradable environmental protection lunch box. Background Art

[0002] Plastic lunch boxes are often used in people's daily diet, especially in fast food restaurants or takeaways. With the increasing awareness of environmental protection, it is required that the plastic tableware used daily should also be environmentally friendly to facilitate degradation and reduce environmental pollution. However, most of the environmentally friendly plastic tableware in the existing market has a single and simple structure, only one layer of structure, which is unstable and firm, easy to deform, and there is no interlayer in the existing plastic lunch box used. All the meals in one lunch box are placed together, which is easy to mix and smell, or multiple lunch boxes are used to place the meals separately, which will cause waste.

[0003] The Chinese utility model with the application number 201520503040.8 proposes a degradable plastic lunch box with an internal interlayer, but there are still some deficiencies:

[0004] First, the size of the space formed by its partition plates cannot be adjusted, and different foods have different requirements for the placement space, which is inconvenient to use.

[0005] Second, when holding food, condensed water will appear on the lid of the box, and thus splash out when the lid is opened, polluting clothes or the dining environment, which is inconvenient.

[0006] Third, when dining, the tray needs to be taken out, and the structure of its tray is not convenient to take out, and the vegetable soup may also spill out during the process of taking it out unilaterally.

[0007] Therefore, the utility model proposes a starch-based degradable environmental protection lunch box to solve the above problems. Utility Model Content

[0008] In order to overcome the above defects in the prior art, the utility model provides a starch-based degradable environmental protection lunch box. By rotating the rotating partition plate, the adjustment of the vegetable holding space can be conveniently realized, which is convenient for holding meals of different sizes. For example, large pork chops require a larger space. By setting a grasping part, the tray can be taken out stably and conveniently. By setting a water-absorbing material layer, the splashing of condensed water can be avoided when the lid is opened.

[0013] Further, two grasping parts that can extend into the groove are provided on the upper side of the tray.

[0014] Further, a vertical shaft is fixedly provided in the middle of the tray, and three groups of rotation blocks that are symmetrically arranged up and down are rotatably provided on the vertical shaft.

[0015] Further, a rotating partition is fixedly provided on each group of the rotation blocks.

[0016] Further, the rotating partition is in close contact with the inner wall of the tray and can move and seal, and the rotating partition is in close contact with the vertical shaft and the rotation blocks and can move and seal.

[0017] Further, a concave cavity for placing dining utensils is provided inside the upper side surface of the box cover.

[0018] Further, notches for cooperating with other rotation blocks are provided on the rotating partition.

[0019] Beneficial effects

[0020] Compared with the prior art, the present utility model has the following beneficial effects: By rotating the rotating partition, the adjustment of the vegetable holding space can be conveniently realized, which is convenient for holding meals of different sizes. For example, large pork ribs require a larger space; by providing the grasping parts, the tray can be stably and conveniently taken out; by providing the water-absorbing material layer, it can be avoided that condensed water splashes when the box cover is opened.
