Description

Technical Field

[0001] The present invention relates to the technical field of kitchen and dining utensils, and particularly to a disposable lunch box. Background Art

[0002] Currently, for takeaway delivery or when users prepare lunch by themselves, lunch boxes are used to pack food. For foods such as soup noodles, two lunch boxes are often used to separately pack the soup and the noodles; or they are packed in two layers in one lunch box, with the soup at the bottom layer and the noodles at the top layer. Then, after receiving the takeaway, the user needs to put the noodles into the soup and mix them before eating. However, during the process of putting the noodles into the soup, the soup often splashes outside the lunch box and onto the hands or the dining table, making it necessary for the user to clean their hands or the dining table, which is very troublesome. Summary of the Invention

[0003] Based on this, the purpose of the present invention is to overcome the shortcomings and deficiencies in the prior art and provide a disposable lunch box.

[0004] A disposable lunch box includes a box body, a partition board, and a cover body;

[0005] The box body is provided with a cavity, and at least one annular groove is provided on the inner wall of the cavity around its circumference;

[0006] The circumferential edge of the partition board can be embedded in the annular groove; a plurality of through holes are provided on the partition board;

[0007] The cover body is arranged above the box body, and the cover body is hermetically connected to the box body.

[0008] For the disposable lunch box of the present invention, by setting the partition board, the soup can be first placed into the box body, then the partition board is embedded in the annular groove, and then the noodles are placed on the partition board. After covering the cover body, the packaging is completed. When it is necessary to eat, the user directly turns the lunch box upside down, so that the noodles fall into the inner space of the cover body, and the soup flows into the cover body through the through holes of the partition board, realizing the mixing of the soup and the noodles. The user can open the box body to eat the noodles. The whole process does not require opening the cover body, which can avoid the situation that the soup splashes outside the lunch box and onto the dining table during the process of putting the noodles into the soup, and at the same time avoid the situation that the soup splashes onto the hands. The present invention has the advantages of simple and ingenious structure, convenient and fast operation, and low cost.

[0009] The present invention can be provided with multiple annular grooves, and then the position of the partition board can be set according to the proportion of the soup and the noodles, improving the adaptability of the lunch box to different situations.

[0010] Further, a storage space is formed by the bottom surface of the cover body being recessed upward. The storage space communicates with the cavity. At least one annular groove is provided on the inner wall of the storage space around its circumference, and the circumferential edge of the partition board can be embedded in the annular groove.

[0011] The beneficial effects of adopting the above further solution are as follows. By recessing the storage space in the lid, it is more convenient to store soup or noodles. There is no need to distinguish between the lid and the box body. Users can hold the soup or water with either the lid or the box body. When in use, only by reversing the lunch box can the soup and noodles be mixed. And when the user fills the soup into the box body, the noodles can be placed in the lid, and the partition board can be embedded in the lid, which is convenient for users to pack separately and then assemble the lid and the box body together. Therefore, users do not need to fill the soup in the box body first, then embed the partition board in the box body, and then place the soup and noodles on the partition board. Vice versa, when the user fills the soup into the lid, the noodles can be placed in the box body, and the partition board can be embedded in the box body, which is convenient for users to pack separately and then assemble the lid and the box body together. Similarly, users do not need to fill the soup in the lid first, then embed the partition board in the lid, and then place the soup and noodles on the partition board.

[0012] Furthermore, the annular grooves of the box body and the lid are respectively and uniformly arranged on the circumferential sides of the inner walls of the corresponding box body and lid from top to bottom.

[0013] The beneficial effects of adopting the above further solution are as follows. By uniformly arranging the annular grooves, it is convenient for users to proportionally distribute the noodles and the soup.

[0014] Furthermore, the opening edges of the box body and the lid respectively extend outward in the circumferential direction to form a first connecting part and a second connecting part, and the first connecting part and the second connecting part are mutually attached. It further includes an annular buckle strip, which is arranged around the circumferential sides of the first connecting part and the second connecting part. The inner ring surface of the annular buckle strip is provided with buckle grooves corresponding to the first connecting part and the second connecting part. The buckle grooves are sleeved outside the first connecting part and the second connecting part, and the connecting parts of the box body and the lid are hermetically connected.

[0015] The beneficial effects of adopting the above further solution are as follows. By setting the annular buckle strip, after the box body and the lid are assembled together, the annular buckle strip can be wound around the first connecting part and the second connecting part, so that the buckle grooves tightly sleeve the first connecting part and the second connecting part, realizing the sealed connection of the lid and the box body.

[0016] Furthermore, a plurality of disconnection grooves are arranged on the top surface of the annular buckle strip along its circumferential direction. The disconnection grooves divide the inner ring surface of the annular buckle strip. The width of the disconnection grooves gradually becomes smaller from the inner ring surface of the annular buckle strip to the direction of its outer ring surface.

[0017] The beneficial effects of adopting the above further solution are as follows. By setting the disconnection grooves, when the annular buckle strip is bent, its inner ring surfaces will not interfere with each other, and thus the annular buckle strip can better fit the first connecting part and the second connecting part.

[0018] Further, a first locking member is provided at the first end of the annular buckle strip, and a second locking member is provided at the second end of the annular buckle strip; the first end and the second end of the annular buckle strip are connected by the first locking member and the second locking member.

[0019] The beneficial effect of adopting the above further solution is that by providing the first locking member and the second locking member, the first end and the second end of the annular buckle strip can be tightly locked, and further, the first connecting portion and the second connecting portion can be tightly and sealingly connected.

[0020] Further, the first locking member is provided with a connecting rack; the second locking member is provided with a connecting tooth groove for inserting the connecting rack.

[0021] The beneficial effect of adopting the above further solution is that by providing the connecting rack and the connecting tooth groove, only by inserting the connecting rack into the connecting tooth groove, the annular buckle strip can be tightened to fasten the first connecting portion and the second connecting portion; by adjusting the depth of insertion of the connecting rack into the connecting slot, the locking degree of the annular buckle strip can be adjusted.

[0022] Further, an arc-shaped convex portion is provided around the circumference of the top surface of the first connecting portion and the second connecting portion, and an arc-shaped concave portion corresponding to the arc-shaped convex portion is provided around the circumference of the bottom surface of the first connecting portion and the second connecting portion; the inner surface shape of the buckle groove is correspondingly arranged with the arc-shaped convex portion and the arc-shaped concave portion.

[0023] The beneficial effect of adopting the above further solution is that by providing the arc-shaped convex portion and the arc-shaped concave portion, the sealing performance of the gap between the first connecting portion and the second connecting portion can be improved, and the soup in the lunch box can be prevented from flowing out from the gap between the first connecting portion and the second connecting portion; at the same time, since the inner surface shape of the buckle groove is correspondingly arranged with the arc-shaped convex portion and the arc-shaped concave portion, the annular buckle strip is not easy to disengage from the first connecting portion and the second connecting portion, and the annular buckle strip can better fasten the first connecting portion and the second connecting portion.

[0024] Further, a circular groove is provided around the circumference of the fitting gap between the first connecting portion and the second connecting portion; a sealing ring is provided in the circular groove.

[0025] The beneficial effect of adopting the above further solution is that by providing the circular groove, the sealing ring can be more conveniently installed, and by providing the sealing ring, the sealing performance of the gap between the first connecting portion and the second connecting portion can be improved.

[0026] Further, reinforcing ribs are provided around the circumference of the top surface and the bottom surface of the partition plate respectively.

[0027] The beneficial effect of adopting the above further solution is that by providing the reinforcing ribs, the overall strength of the partition plate can be improved, and it is convenient to place more flour and noodle foods.

[0028] For better understanding and implementation, the present invention will be described in detail below with reference to the accompanying drawings. Description of the Drawings
