[0001] The utility model relates to the technical field of lunch boxes, in particular to a disposable lunch box which can prevent a port of a box body from being deformed. Background Art
[0002] Generally, the lid of a take-out box is buckled on the outside of the upper end of the box. When the box is squeezed by a lateral external force from the side or when the box is stacked on the lid to bear the weight, the lid and the box will bend and deform, creating a gap between them, causing leakage or detachment of the lid.
[0003] This case arises to solve the above problems. Utility Model Content
[0004] Therefore, in view of the above problems, the present invention proposes a disposable lunch box with a reasonable structural design, which can effectively prevent food from leaking and prevent the deformation of the box body port.
[0005] In order to solve the above technical problems, the solution adopted by the utility model is: a disposable lunch box that prevents the deformation of the box body port, comprising a box body and a cover body, the cover body and the box body are detachably sealed and buckled, the cover body is located on the inner wall of the port of the box body and is provided with an inner reinforcement part, which is always tightly fitted with the inner wall of the box body when the box body is squeezed by external force from the side and when the cover body is subjected to load, and prevents the box body and the cover body from deforming and avoiding leakage, the upper end of the inner reinforcement part is integrally arranged on the inner surface of the cover body, the lower end of the inner reinforcement part is inclined inwardly, and the angle of the acute angle formed by the inner reinforcement part and the horizontal line is greater than the angle of the acute angle formed by the side wall of the box body and the horizontal line.
[0006] A further improvement is that: a transverse reinforcement rib for strengthening the force of the internal reinforcement part is arranged on the inner surface of the cover body and located on the inner side of the internal reinforcement part, the upper end of the transverse reinforcement rib is integrally arranged on the cover body, the outer side of the transverse reinforcement rib is connected to the internal reinforcement part, and the longitudinal width of the transverse reinforcement rib is not greater than one third of the longitudinal height of the internal reinforcement part.
[0007] A further improvement is that the middle portion of the cover body is recessed from top to bottom to form a stacking groove for preventing the stacked lunch boxes from shifting left and right when stacking the lunch boxes, and the inner side of the transverse reinforcing rib is connected to the side wall of the stacking groove.
[0008] A further improvement is that: the cover body is located at the reinforcing rib and is recessed from top to bottom to form a concave platform connected to the stacking groove, and the inner edge angle of the concave platform is an arc angle.
[0009] A further improvement is that the box body is in the shape of a cylinder or a truncated cone or a prism with at least three edges or a prism with at least three edges, and the cover body is in the shape of a circle or a polygon with more than three sides.
[0010] A further improvement is that the reinforcement part is arranged in a closed loop around the cover body and connected end to end, or is arranged in multiple sections at intervals around the cover body.
[0011] A further improvement is that the transverse reinforcing ribs are evenly spaced around the cover body.
[0012] By adopting the above technical solution, the beneficial effects of the utility model are:
[0013] In the present case, an internal reinforcement part is arranged on the inner surface of the cover body. When the box body is squeezed by an external force from the side and when the cover body is subjected to load, the internal reinforcement part can always be tightly pressed against the inner wall of the box body to prevent the box body and the cover body from deforming, thereby avoiding leakage due to a gap between the cover body and the box door. The internal reinforcement part is made integrally with the cover body, and the entire scheme only changes the mold of the cover body, while the box body can still use the original mold, and the improvement cost is relatively low. The lower end of the internal reinforcement part is inclined inwardly to form a snap-fitting gap with the outer edge of the cover body, and the snap-fitting gap facilitates the positioning and snapping of the cover body and the box body. After the cover body and the box body are snapped together, the internal reinforcement part presses against the inner wall of the box body, thereby increasing the tightness of the connection between the box body and the cover body and effectively preventing leakage.
[0014] A further beneficial effect is: in the present case, transverse reinforcing ribs are arranged on the inner surface of the cover body, inside the inner reinforcement part; the transverse reinforcing ribs increase the transverse pressing force of the inner reinforcement part, which can further hinder the deformation of the box body port and the cover body, and effectively prevent food from leaking; the longitudinal width of the transverse reinforcing ribs is not greater than one-third of the longitudinal height of the inner reinforcement part, and does not affect the deformation coordination between the lower end of the inner reinforcement part and the box body; after the cover body is closed, the reinforcing ribs are located at the port of the box body, which can enhance the strength of the force that hinders the deformation of the port.
[0015] A further beneficial effect is that the stacking grooves provided in the present case can prevent the upper lunch boxes from shifting laterally when stacking lunch boxes, making it easier to pack them in bags. After the cover body is loaded with stacked lunch boxes, the middle part of the cover body will sink. The reinforcing ribs can increase the load-bearing capacity of the cover body, and at the same time, transmit the load-bearing force laterally to further increase the sealing of the cover body and the box body.
[0016] A further beneficial effect is that in this case, the cover body is recessed from top to bottom at the reinforcing rib to form a concave platform connected to the stacking groove, and the inner edge angle of the concave platform is an arc angle. After the arc angle is subjected to force, it deforms downward and drives the reinforcing rib to drag the inner reinforcement part to press against the box body. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.
[0021] refer to Figures 1 to 3 The embodiment of the utility model discloses a disposable lunch box that prevents the deformation of the box body port, including a box body 10 and a cover body 11. The cover body 11 is detachably sealed with the box body 10. The shape of the box body 10 is cylindrical or truncated cone or a prism with at least three edges or a prism with at least three edges. The shape of the cover body 11 is circular or a polygon with more than three sides. The cover body 11 is located on the inner wall of the port of the box body 10 and is provided with an inner reinforcement part 12 which is always tightly fitted with the inner wall of the box body 10 when the box body 10 is squeezed by an external force from the side and when the cover body 11 is subjected to load, so as to prevent the box body 10 and the cover body 11 from deforming and avoiding leakage. The reinforcement part is a closed loop setting connected end to end around the cover body 11 or a multiple-segment setting at intervals around the cover body 11. The upper end of the inner reinforcement part 12 is integrally arranged on the inner surface of the cover body 11, and the lower end of the inner reinforcement part 12 is inclined inwardly so that the lower end of the inner reinforcement part 12 can extend into the port of the box body 10 independently when the cover body 11 is buckled. The angle of the acute angle formed by the inner reinforcement part 12 and the horizontal line is greater than the angle of the acute angle formed by the side wall of the box body 10 and the horizontal line. When the cover body 11 and the box body 10 are buckled, the lower end of the inner reinforcement part 12 is forced to deform and press against the box body 10.
[0022] On the inner surface of the cover body 11, inside the inner reinforcement part 12, there are transverse reinforcement ribs 13 for reinforcing the force of the inner reinforcement part 12. The transverse reinforcement ribs 13 are evenly spaced around the cover body 11. The upper end of the transverse reinforcement ribs 13 is integrally provided on the cover body 11. The outer side of the transverse reinforcement ribs 13 is connected to the inner reinforcement part 12. The longitudinal width of the transverse reinforcement ribs 13 is not greater than one third of the longitudinal height of the inner reinforcement part 12, and does not affect the deformation coordination between the lower end of the inner reinforcement part 12 and the box body 10. After the cover body 11 is closed, the reinforcement ribs are located at the port of the box body 10, which can enhance the strength of the force that hinders the deformation of the port.
[0023] The middle part of the cover body 11 is recessed from top to bottom to form a stacking groove 14 for preventing the stacked lunch boxes from shifting left and right when stacking the lunch boxes. The inner side of the transverse reinforcing rib 13 is connected to the side wall of the stacking groove 14. After the cover body 11 is loaded with the stacked lunch boxes, the middle part of the cover body 11 will sink. The reinforcing rib can increase the load-bearing capacity of the cover body 11, and at the same time, the load-bearing force is transversely transmitted to further increase the sealing performance of the cover body 11 and the box body 10.
[0024] The cover body 11 is located at the reinforcing rib and is recessed from top to bottom to form a concave platform 15 connected to the stacking groove 14. The inner edge angle of the concave platform 15 is an arc angle 16. The concave platform facilitates the cover body 11 to drive the reinforcing rib to press against the box body 10 after bearing the load.
