[0030] When packaging materials, packaging boxes are usually used. When the types or quantities of the packaged materials are large, two or more packaging boxes are needed to be used for separate packaging, and the packaged packaging boxes are stacked for transportation. However, when the stacked packaging boxes are transported at one time, shaking is likely to occur, causing the upper packaging boxes to accidentally fall. In order to avoid this situation, some existing packaging boxes include a bottom box part 100, a box cover part 200 and two pairs of overlapping parts, the box cover part 200 is detachably covered on the bottom box part 100, and the paired overlapping parts are respectively rotated and arranged on opposite sides of the box cover part 200. When two or more packaging boxes are stacked, the packaging box below rotates the overlapping parts to overlap and fix the packaging box above, so that the stacking of the packaging boxes is relatively stable. However, the design of the overlapping parts makes the above-mentioned packaging box structure relatively complicated and relatively troublesome to operate and use.

[0031] Reference Figures 1 to 7 , is a stackable packaging box of an embodiment of the utility model, comprising a bottom box 100 and a cover 200. The bottom box 100 is provided with a material containing groove 110, and at least two clamping parts 120 are provided at the lower end of the bottom box 100; the cover 200 is detachably provided at the upper end of the bottom box 100 and can cover or open the material containing groove 110, and the cover 200 is provided with clamping fitting parts 210 corresponding to the number of the clamping parts 120, and the clamping fitting parts 210 are adapted to the clamping parts 120, and when the clamping parts 120 are clamped with the clamping fitting parts 210, the position of the bottom box 100 relative to the cover 200 can be limited. When two or more packaging boxes are stacked, in two adjacent packaging boxes, the snap-fitting portion 120 of the bottom box member 100 can be snap-fitted with the snap-fitting portion 210 of the lower box cover member 200, so that the stacked packaging boxes are relatively stable; and the snap-fitting portion 120 is directly provided on the bottom box member 100 and the snap-fitting portion 210 is provided on the box cover member 200, so the number of parts of the packaging box is reduced, thereby simplifying the structure of the packaging box and facilitating use.

[0032] In the embodiment, the clamping portion 120 is a clamping slot, and the clamping fitting portion 210 is a clamping hook. The clamping slot and the clamping hook are used to clamp the bottom box member 100 and the box cover member 200 when the packaging boxes are stacked, so that the two are relatively stable when stacked, and the structure is simple and easy to implement. It is conceivable that the clamping portion 120 can also be a clamping hook, and the clamping fitting portion 210 can be a clamping slot.

[0033] Specifically, the hook is integrally formed on the box cover 200 , and the slot is integrally formed on the bottom box 100 .

[0034] In an embodiment, a limiting platform 130 is provided at the lower end of the bottom box member 100, and a limiting groove 220 is provided at the upper part of the box cover member 200. The limiting platform 130 is adapted to the limiting groove 220, the snap-fitting portion 120 is provided on the side wall of the limiting platform 130, and the snap-fitting portion 210 is provided on the hole wall of the limiting groove 220.

When the packaging boxes are stacked, the limiting platform 130 is inserted into the limiting groove 220, and the snap-fitting portion 120 is snap-fitted with the snap-fitting portion 210. The hole wall of the limiting groove 220 can abut against the side wall of the limiting platform 130, further horizontally limiting the position of the bottom box component 100 and the box cover component 200, and cooperating with the snap-fitting portion 120 and the snap-fitting portion 210 for snap-fitting and limiting, so that the stacking of the packaging boxes is more stable and reliable; the snap groove is provided on the side wall of the limiting platform 130, and the snap hook is provided on the hole wall of the limiting groove 220, and the structure is relatively compact.

[0035] It is conceivable that, in some embodiments, a plurality of slots may be directly provided at the lower end of the bottom box member 100 , and a plurality of hooks may be convexly formed at the upper end of the box cover member 200 , without providing the limiting platform 130 and the limiting groove 220 .

[0036] Specifically, the outer side of the limiting platform 130 is provided with a limiting groove 140 extending in the up-down direction, and the hole wall of the limiting groove 220 is provided with a limiting rib 230 extending in the up-down direction, and the limiting rib 230 is adapted to the limiting groove 140, the clamping part 120 is provided at the upper end of the limiting groove 140, and the clamping matching part 210 is provided at the upper end of the limiting rib 230. The limiting groove 140 and the limiting rib 230 are provided, and when the packaging boxes are stacked, the limiting groove 140 can abut against the limiting rib 230, further limiting the position of the limiting platform 130 relative to the limiting groove 220, making it less likely for the two to shake relative to each other during transportation, and also making the structural strength of the box cover 200 and the bottom box 100 better.

[0037] In the embodiment, the upper and lower sides of the hook are provided with guide surfaces 211, so that the end of the hook is a narrow end. The guide surfaces 211 are provided, and when two packaging boxes are stacked, one of the bottom box parts 100 is placed downward on the box cover part 200, and at this time, the periphery of the limiting platform part 130 of the bottom box part 100 can contact the upper guide surface 211, and under the guidance of the guide surface 211, the limiting platform part 130 can be inserted into the limiting groove 220 more quickly and accurately, and it is convenient for the hook to undergo a small amount of elastic deformation and be inserted into the slot; when it is necessary to separate the two packaging boxes, a large force is applied to pull out the upper packaging box upward, and the slot wall of the slot pushes the lower guide surface 211, so that the hook is more easily elastically deformed and allows the hook to be separated from the slot, reducing the difficulty of separating the two packaging boxes from each other.

[0038] In the embodiment, the bottom box 100 is provided with a plurality of clamping parts 120, and all the clamping parts 120 are evenly arranged around the outer side of the bottom box 100. The plurality of evenly arranged clamping parts 120 are provided so that when the packaging boxes are stacked, the stacking stability is relatively balanced and the use effect is better. When there are two clamping parts 120, the two clamping parts 120 are respectively placed on opposite sides of the bottom box 100.

[0039] In the embodiment, the bottom box 100 is provided with four clamping parts 120, and the box cover 200 is correspondingly provided with four clamping matching parts 210. Since the bottom box 100 of the present embodiment is approximately rectangular or elliptical in overall shape when viewed from above, the four clamping parts 120 are evenly arranged, and the four clamping parts 120 are respectively located at the front, back, left and right sides of the bottom box 100, the structure is simple and easy to implement. It can be understood that in other embodiments, the overall approximate shape of the bottom box 100 when viewed from above can also be other shapes, such as circular, polygonal or irregular, and those skilled in the art can make specific configurations according to actual needs.

[0040] It is conceivable that the outer side of the bottom box 100 may also be evenly distributed with two, three or more snap-fitting parts 120, and the corresponding box cover 200 may also be correspondingly provided with two, three or more snap-fitting parts 210. Those skilled in the art may make specific configurations according to actual needs; it is understandable that the snap-fitting parts 120 may not be evenly arranged, as long as the snap-fit ​​connection can be achieved when the packaging boxes are stacked so that the stacking is stable.

[0041] In the embodiment, a boss portion 111 is protruding from the bottom wall of the material receiving groove 110. The boss portion 111 is provided so that the lower end of the bottom box 100 has higher strength, a simple structure, and is easy to implement.

[0042] In the embodiment, the edge of the bottom box 100 is provided with a first gripping piece 150, and the edge of the box cover 200 is provided with a second gripping piece 240, and the first gripping piece 150 and the second gripping piece 240 are partially staggered in the horizontal direction. When the box cover 200 needs to be opened, it is usually difficult for the user to directly and firmly grasp the bottom box 100 and the box cover 200 with their hands, so the first gripping piece 150 and the second gripping piece 240 are provided, and the user grasps the first gripping piece 150 and the second gripping piece 240 with both hands respectively, and separates the bottom box 100 and the box cover 200 with force, so that the bottom box 100 is more easily separated from the box cover 200, thereby opening the box, and the structure is simple and easy to implement; the first gripping piece 150 and the second gripping piece 240 are partially staggered in the horizontal direction, and the first gripping piece 150 and the second gripping piece 240 can be grasped more accurately and easily.

[0043] In an embodiment, the bottom box 100 is a plastic part, and the cover 200 is a plastic part. The bottom box 100 and the cover 200 are made of plastic, and the material is relatively easy to obtain and has good elasticity. Specifically, the cover 200 can be made of transparent plastic, such as transparent polypropylene, or other plastic materials, such as polyethylene, polyester, polyamide, etc. The bottom box 100 can be made of transparent or opaque polypropylene, or other plastic materials, such as polyethylene, polyester, polyamide, etc. It is conceivable that the bottom box 100 can also be made of paper material, and the cover 200 is made of plastic; or the bottom box 100 is made of plastic, and the cover 200 is made of paper material; or both the bottom box 100 and the cover 200 are made of paper material.

[0044] Specifically, the box cover 200 is provided with a ring-shaped mating groove which is closed at both ends, and the periphery of the slot of the material receiving groove 110 of the bottom box 100 is also ring-shaped which is closed at both ends. The periphery of the slot of the material receiving groove 110 of the bottom box 100 can be detachably clamped in the mating groove, so that the box cover 200 and the bottom box 100 can be detachably connected.

[0045] Specifically, in some embodiments, a partition may be provided in the material containing groove 110 of the bottom box 100 to separate the material containing groove 110 into several areas for facilitating the placement of different foods.

[0046] Specifically, the cover 200 and the bottom box 100 are thin-walled parts with substantially uniform thickness, which saves production materials, has low production costs, and has relatively good applicability. The thickness of the cover 200 and the bottom box 100 is specifically configured by those skilled in the art according to actual needs.

[0047] Specifically, the box cover 200 is also provided with exhaust holes, which makes the packaging box more suitable for packaging food and heating in a microwave oven or oven. When heating in a microwave oven or oven, the exhaust holes can balance the air pressure inside and outside the packaging box, preventing the packaging box from bursting due to excessive internal pressure during heating, and timely discharging excess moisture in the packaging box.

[0048] Specifically, the stackable packaging box of the present invention can be used for food packaging. Of course, the stackable packaging box of the present invention can also be used for packaging materials in other fields, which is not limited here.
