Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lunch boxes, in particular to an anti-suction lunch box. Background Art
[0002] Lunch boxes are widely used in modern life. To save storage and transportation space, lunch boxes are overlapped and packaged before use and taken as needed during use. For easy access, a certain gap needs to be reserved between the stacked lunch boxes, and air circulation with the outside world is also required in these gaps after stacking. Only in this way can it be ensured that when taking, the two lunch boxes are not too tightly attached, and multiple lunch boxes can be taken out simultaneously. However, the common lunch boxes currently lack such detailed designs, so it often happens that the stacked lunch boxes are difficult to separate after being sucked together, causing inconvenience in use. Summary of the Invention
[0003] Aiming at the deficiencies of the above-mentioned prior art, the purpose of the utility model is to provide an anti-suction lunch box with a simple and reasonable structure, small occupied space during storage and transportation, and very convenient and fast access.
[0004] The utility model realizes the above purpose in the following way:
[0005] The anti-suction lunch box of the utility model includes a box body that is wider at the top and narrower at the bottom. The outer surface of the upper part of the box body is convexly provided with a functional ring. The bottom of the functional ring protrudes from the outer surface of the corresponding box body. A plurality of longitudinal convex ribs are arranged at intervals along the transverse direction on the outer surface of the functional ring.
[0006] Further, the box body is in a conical shape that is wider at the top and narrower at the bottom, and the functional ring is annularly convexly arranged outside the box body.
[0007] Further, the functional ring is formed by expanding outward from the inner wall of the box body.
[0008] Further, the inner wall at the opening of the box body expands outward to form an expansion ring corresponding to the outer contour of the functional ring and the longitudinal convex ribs. The expansion ring is located above the functional ring.
[0009] Further, long convex ribs that protrude downward from the bottom edge of the functional ring are also arranged at intervals along the transverse direction on the outer surface of the functional ring.
[0010] Further, the upper edge of the expansion ring expands and turns outward to form an outward turning edge.
[0011] Advantages of the present utility model: The present utility model provides an anti-suction meal box, which includes a box body that is wider at the top and narrower at the bottom. The outer surface of the upper part of the box body is convexly provided with a functional ring. The bottom of the functional ring protrudes from the outer surface of the corresponding box body. A plurality of longitudinal ridges are arranged at intervals along the transverse direction on the outer surface of the functional ring. The outer diameter of the bottom of the box body is smaller than that of the top, enabling nested stacking. And near the opening of the box body, the outer contour diameter of the functional ring is larger than the outer wall of the box body. When two box bodies are stacked, the outer contour of the functional ring of the inner box body contacts the inner wall of the outer box body, while the upper and lower parts of the inner box body do not contact the inner wall of the outer box body and there are gaps. Specifically, since there are longitudinal ridges on the outer surface of the functional ring, it is actually the outer surfaces of these longitudinal ridges that contact the inner wall of the outer box body, and the gaps between two adjacent longitudinal ridges do not contact. In this way, these gaps connect the upper and lower gaps of the functional ring. Thus, when taking out a stacked box body, the design of upper and lower connection can ensure the smooth rotation or separation of the box body. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] As shown in reference to Figures 1 to 4 a kind of anti-suction meal box is shown, which includes a box body 1 that is wider at the top and narrower at the bottom. The outer surface of the upper part of the box body 1 is convexly provided with a functional ring 12. The bottom of the functional ring 12 protrudes from the outer surface of the corresponding box body 1. A plurality of longitudinal ridges 13 are arranged at intervals along the transverse direction on the outer surface of the functional ring 12.
[0019] As shown in the attached drawings, the outer diameter of the bottom of the box body 1 is smaller than that of the top, enabling nested stacking. The functional ring 12 is located near the opening of the box body 1, and its outer contour diameter is larger than the outer wall of the box body 1. When two box bodies 1 are stacked, the outer contour of the functional ring 12 of the inner box body contacts the inner wall of the outer box body, while the upper and lower parts of the inner box body do not contact the inner wall of the outer box body and there are gaps. Specifically, since there are longitudinal ridges 13 on the outer surface of the functional ring 12, it is actually the outer surfaces of these longitudinal ridges 13 that contact the inner wall of the outer box body, and the gaps between the two longitudinally spaced longitudinal ridges 13 do not contact. In this way, the upper and lower gaps of the functional ring 12 are connected through these gaps. Thus, when taking out a stacked box body, the upper and lower connected design can ensure the smooth rotation or separation of the box body.
[0020] Further, the box body 1 is in the shape of a conical frustum with a wider top and a narrower bottom, and the functional ring 12 is annularly protruded outside the box body 1.
[0021] As shown in the attached drawings, the overall shape is conical frustum, which is convenient for overlapping placement. The functional ring 12 can be intermittently protruded, preferably annularly protruded integrally. The longitudinally spaced longitudinal ridges 13 are evenly arranged on this integrally annularly protruded functional ring 12, which can increase the wall thickness of the box body 1 at this position and enhance the anti-deformation strength of the box body.
[0022] Further, the functional ring 12 is formed by expanding outward from the inner wall of the box body 1.
[0023] As shown in the attached drawings, a monolithic annular functional ring 12 is formed by expanding outward along the height of the functional ring 12 on the inner wall of the box body 1. On the one hand, it is convenient for processing and forming, and at the same time, the shape of the functional ring 12 is guaranteed, preventing deformation due to heat or force and affecting the supporting effect of the longitudinal ridges 13 thereon.
[0024] Further, the inner wall at the opening of the box body 1 expands outward to form an expansion ring 14 corresponding to the outer contours of the functional ring 12 and the longitudinal ridges 13, and the expansion ring 14 is located above the functional ring 12.
[0025] As shown in the attached drawings, on the outer wall of the box body 1 from top to bottom are the expansion ring 14 with a gradually decreasing outer diameter, the functional ring 12, and the outer wall of the box body 1. When two box bodies 1 are stacked, the functional ring 12 of the upper box body just inserts downward into the expansion ring 14 of the lower box body, and the longitudinal ridges 13 and the bottom edge of the functional ring 12 just abut against the bottom edge inside the expansion ring 14, restricting the further downward movement of the upper box body; while the outer surfaces of the longitudinal ridges 13 can abut against the inner wall of the expansion ring 14 to prevent close contact, keeping the gaps between the longitudinal ridges 13 upper and lower connected and ensuring the smooth rotation or separation of the box body.
[0026] Further, the outer surface of the functional ring 12 is also provided with long ridges 15 protruding downward at intervals in the transverse direction and protruding beyond the bottom edge of the functional ring 12.
[0027] As shown in the attached drawings, a plurality of long convex ribs 15 are arranged at intervals outside the functional ring 12. The interval distance between them is greater than that between the longitudinal convex ribs 13. Their longitudinal length is relatively long, and they extend downward at the bottom and protrude beyond the lower edge of the functional ring 12. Their width and thickness are also larger than those of the longitudinal convex ribs 13. When two boxes 1 are stacked, the bottom edge of the long convex rib 15 of the upper box abuts against the bottom edge of the expansion ring 14. While restricting the further downward movement of the upper box, it can also connect the gaps between adjacent longitudinal convex ribs 13, making it easier for the boxes to rotate or separate.
[0028] Furthermore, the upper edge of the expansion ring 14 is turned outwards to form an outward-turned edge 16.
[0029] As shown in the attached drawings, the outward-turned edge 16 is formed by turning outwards. Its surface is smoothly transitioned from the inner wall of the expansion ring 14 outwards. On the one hand, it strengthens the strength of the opening of the box, preventing deformation during taking and placing. At the same time, it also ensures that the upper box can be placed into the smooth opening without obstacles when stacked.
