[0001] The utility model relates to the technical field of takeaway packaging boxes, and particularly relates to a takeaway packaging box with anti-slip stacking function. Background Art
[0002] With the rapid development of the takeaway industry, the demand for takeaway packaging boxes is increasing day by day. Traditional takeaway packaging boxes usually consist of a box body and a lid. The lid is used to seal the box body to protect the food inside from being contaminated and is convenient for carrying. However, in the existing design of takeaway packaging boxes, the surfaces of the box body and the lid are usually smooth, and there is a lack of effective limiting structures to ensure the stability when multiple packaging boxes are stacked.
[0003] During actual use, especially during the delivery process, multiple packaging boxes need to be stacked together for transportation. However, due to the overly smooth contact surface between the box body and the lid, when the vehicle encounters bumps or sharp turns during driving, the stacked packaging boxes are prone to relative sliding, resulting in the packaging boxes being skewed or even toppled. In this case, not only may the food spill, affecting the quality of the food and the dining experience of customers, but it will also cause inconvenience to the delivery staff and increase the delivery difficulty.
[0004] Therefore, this application proposes a takeaway packaging box that can achieve anti-slip stacking effect to solve the above problems. Summary of the Utility Model
[0005] Aiming at the deficiencies in the background art, the utility model provides a takeaway packaging box with anti-slip stacking function.
[0006] The technical solution adopted by the utility model is: a takeaway packaging box with anti-slip stacking function, including a box body and a lid covering the box body. An engaging step is provided on the inner side of the surface of the lid, and an embedding step is provided inside the engaging step. A to-be-engaged step that can be engaged inside the engaging step is provided on the bottom surface of the box body, and an annular engaging groove that is mutually engaged with the above-mentioned embedding step is provided on the outer side of the to-be-engaged step.
[0007] Furthermore, positioning bosses are provided at both ends of the surface of the lid located inside the engaging step, and positioning grooves that are mutually engaged with the above-mentioned positioning bosses are provided on the bottom surface of the box body.
[0008] Furthermore, both the positioning bosses and the positioning grooves are cross-shaped structures that are mutually adapted.
[0009] Further, an "n"-shaped covering portion is provided on the outer ring of the box body. The end of the "n"-shaped covering portion has a limiting extension portion that slopes outward. The outer ring of the opening of the cover body has a covering boss that protrudes and fits with the "n"-shaped covering portion. A covering groove is provided on the outer ring of the covering boss. The outer side of the covering groove has a shrinking inclined surface that slopes inward and contracts, and the inner side of the covering groove has a pressing step that protrudes outward.
[0010] Further, a first convex ring is provided at the end of the limiting extension portion, and a second convex ring is provided inside the shrinking inclined surface.
[0011] Further, a heightening convex ring is provided above the limiting extension portion.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0024] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.
[0025] The present invention provides an anti-slip stacked takeaway packaging box.
[0026] In this embodiment, referring to Figures 1-4 , this anti-slip stacked takeaway packaging box includes a box body 1 and a cover body 2 covering the box body 1. An annular latching step 3 is provided on the inner side of the surface of the cover body 2. An annular fitting step 4 is provided inside the latching step 3. An annular latchable step 5 that can be latched inside the latching step is provided on the bottom surface of the box body. An annular latching groove 6 that is mutually fitted with the above-mentioned fitting step is provided outside the latchable step 5.
[0027] During specific use, the latchable step at the bottom of the box body of the upper-layer packaging box is aligned with and pressed into the latching step on the cover body of the lower-layer packaging box, so that the fitting step and the annular latching groove are mutually fitted, forming a stable locking system when the upper and lower-layer packaging boxes are stacked, effectively preventing the slip between the packaging boxes and improving the safety and reliability during transportation.
[0028] As Figure 2 shown, the annular latching groove is an arc-shaped concave surface, and the corresponding fitting step is also a convex ring structure with an arc-shaped cross-section. The two are mutually fitted to play a limiting role.
[0029] Specifically, positioning bosses 7 are provided at both ends of the surface of the cover body located inside the snap-in step, and positioning grooves 8 that are fitted with the above-mentioned positioning bosses are provided on the bottom surface of the box body.
[0030] In this embodiment, the design of the positioning bosses and positioning grooves is added, further strengthening the precise positioning when the packaging boxes are stacked. The fitting of the positioning bosses and positioning grooves not only helps to quickly and accurately complete the stacking of the packaging boxes, but also restricts the displacement of the packaging boxes in the lateral direction, making the stacking more firm.
[0031] Specifically, both the positioning bosses and the positioning grooves are cross-shaped structures that are adapted to each other.
[0032] In this embodiment, by designing the positioning bosses and positioning grooves as cross-shaped structures, not only the positioning accuracy is ensured, but also a multi-directional limiting effect is provided. This design makes it difficult for the packaging box to shift even under the action of an external force, further improving the stability in the stacked state.
[0033] Specifically, an "n"-shaped covering portion 9 is provided on the outer ring of the box body. The end of the "n"-shaped covering portion 9 has a limiting extension portion 10 that inclines outward. The outer ring of the opening of the cover body has a covering boss 11 that protrudes and is fitted with the "n"-shaped covering portion. A covering groove 12 is provided on the outer ring of the covering boss 11. The outer side of the covering groove has a shrinking inclined surface 13 that inclines inward and contracts, and the inner side of the covering groove 12 has a pressing step 14 that protrudes outward.
[0034] In this embodiment, as Figure 4 shown, by providing the "n"-shaped covering portion and the covering boss, after the cover body is covered on the box body, the "n"-shaped covering portion can be covered on the covering boss. At this time, the limiting extension portion extends into the covering groove. At the same time, the limiting extension portion is pressed against the shrinking inclined surface by cooperating with the pressing step, so that the limiting extension portion is pressed and restricted between the shrinking inclined surface and the pressing step, and the cover body cannot be removed without damaging the shape of the cover body, achieving a good anti-theft effect.
[0035] Specifically, a first convex ring 15 is provided at the end of the limiting extension portion, and a second convex ring 16 is provided inside the shrinking inclined surface.
[0036] In this embodiment, the anti-theft effect is further enhanced by providing the first convex ring and the second convex ring.
[0037] Specifically, a heightening convex ring 17 is provided above the limiting extension portion.
[0038] In this embodiment, by adding the heightening convex ring, the middle part of the "n"-shaped covering portion is slightly warped outward. Cooperating with the inclined shrinking inclined surface, the self-locking anti-theft effect can be further improved.
[0039] Specifically, a reinforcing step ring 18 is provided on the surface of the cover body on the outer ring of the fastening step, and a plurality of reinforcing bars 19 are arranged between the reinforcing step ring and the fastening step.
[0040] In this embodiment, by providing the reinforcing bars and the reinforcing step ring, the strength of the fastening step is increased, and the stability of the connection and fastening is improved.
[0041] All technicians should note that although the present utility model has been described according to the above specific embodiments, the idea of the present utility model is not limited to this utility model only. Any modification using the idea of the present utility model will be included in the scope of protection of this patent right.
