Technical Field
[0001] The utility model relates to the technical field of lunch boxes, in particular to a degradable lunch box with good sealing performance. Background Art
[0002] A degradable lunch box refers to a lunch box that can be degraded into carbon dioxide and water through biochemical reactions under the action of microorganisms (such as bacteria, molds, and algae) and enzymes in the natural environment. The degradation process of this lunch box does not require manual participation and has less impact on the environment. The materials of degradable lunch boxes are mainly divided into two categories: new stone lunch boxes: made of new stones such as paper products, straws, starches, etc. These lunch boxes can be completely degraded and are also called environmental protection products. For example, corn starch-based lunch boxes are one of the more common degradable lunch boxes on the market. They are made of natural corn starch and plant fibers as the base materials, supplemented with substances such as biodegradable polyester and polyols, and have the advantages of being degradable, having good strength, being leak-proof, having no peculiar smell, heat resistance, and oil resistance; plastic-based lunch boxes: mainly composed of plastics, added with substances such as starch and photosensitizers. Although these lunch boxes have the characteristics of being degradable, they may face some problems during the degradation process, such as uncertain degradation time, poor tolerance, and difficulty in recycling.
[0003] During the use of existing degradable lunch boxes, gaps are easily separated at the connection between the bottom box and the top cover of the lunch box, resulting in food leakage inside the degradable lunch box, poor sealing performance, and affecting the normal use of users. Therefore, generally when packing food, a film is wound around the connection between the bottom box and the top cover of the lunch box several times to achieve the effect of increasing the seal. This structure requires operators to wind and seal and then cut the film, which is rather troublesome and affects the packing efficiency. Therefore, the utility model proposes a degradable lunch box with good sealing performance to solve the problems existing in the prior art. Summary of the Utility Model
[0004] In view of the above problems, the utility model proposes a degradable lunch box with good sealing performance, which improves the sealing and packing efficiency while ensuring the sealing performance.
[0005] To achieve the purpose of the utility model, the utility model is realized through the following technical solutions: A degradable lunch box with good sealing performance includes a degradable box body and a degradable box cover. An installation edge is provided at the edge of the top of the degradable box body, and the degradable box cover is covered above the installation edge. A film ring is provided below the outer side of the degradable box cover, and the lower part of the film ring extends out of the bottom of the degradable box cover. The film ring has at least two layers, and an inner cavity is provided between the two film rings.
[0006] A tensioning wire is provided inside the inner cavity. On one side of the outer film ring, there are two sets of insertion holes. The two ends of the tensioning wire extend out of the two sets of insertion holes respectively, and tensioning heads are connected to the two ends of the tensioning wire. Above one side of the degradation box body, there is a fixing component adapted to the tensioning heads.
[0007] A further improvement lies in that: the fixing component includes a fixing rod and a ball head. The fixing rod is connected to the degradation box body. The ball head is arranged at one end of the fixing rod. The tensioning head is used to be wound and connected to the fixing rod and is limited by the ball head.
[0008] A further improvement lies in that: the degradation box body and the installation edge are integrally formed, the degradation box body and the fixing rod are integrally formed, and the fixing rod and the ball head are integrally formed.
[0009] A further improvement lies in that: below the inner side of the degradation box cover, there is an inner convex ring, and between the inner convex ring and the inner side of the degradation box cover, there is a card slot, and the card slot is adapted to the installation edge.
[0010] A further improvement lies in that: at the top of the installation edge, there is a circular convex edge, and the thickness of the circular convex edge is greater than the thickness of the installation edge. Inside the card slot, there is an inner arc groove adapted to the circular convex edge.
[0011] A further improvement lies in that: at the middle position of the top of the degradation box cover, there is an embedded groove, and inside the embedded groove, there is a handle.
[0012] A further improvement lies in that: on the outer side of the installation edge, there are multiple sets of groove rings, and the groove rings are adapted to the tensioning wire.
[0013] The beneficial effects of the present utility model are as follows:
[0014] 1. The present utility model connects the film ring and the degradation box cover into one body. When packing, the degradation box cover is covered on the installation edge. By smoothing the film ring to cover the connection between the degradation box cover and the installation edge, pulling the tensioning head makes the tensioning wire tighten, so that the film ring tightly wraps the connection between the degradation box cover and the installation edge. Winding the tensioning head around the fixing component can complete the sealing and fixing, which improves the sealing and packing efficiency while ensuring the sealing performance.
[0015] 2. When the degradation box cover is covered on the installation edge, the installation edge is inserted into the card slot between the inner convex ring and the inner side of the degradation box cover, and the circular convex edge on the installation edge is clamped with the inner arc groove inside the card slot, so as to achieve the purpose of fixing, and the clamping insertion further improves the sealing performance.
