[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this utility model, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms such as "upper," "lower," "left," "right," "top," "bottom," "side," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this utility model.
[0026] like Figure 1 and Figure 3 As shown, the interlocking packaging box of this utility model includes a box body 100, an inner cover 101, and an outer cover 102. The box body 100 has a top opening. The inner cover 101 and the outer cover 102 are connected to the opposite edges of the top opening. The inner cover 101 is provided with a convex locking hole 103. The outer cover 102 has an arc notch 108 on the opposite edge of the top opening. The edges on both sides of the arc notch are connected to a buckle plate 104. The buckle plate has an arc buckle 105 on the edge connecting to the outer cover 102. The arc buckle 105 corresponds to the arc notch 108 in position and shape. Both ends of the arc buckle 105 have a single-slit cut 106. After the top opening is closed, the inner cover 101 is located below the outer cover 102. The arc buckle 105 is inserted into the convex locking hole 103. The two protruding shoulders 110 inside the convex locking hole 103 are precisely embedded in the single-slit cuts 106 at both ends of the arc buckle 105, thereby achieving locking. In this embodiment, the arc-shaped buckle 105 and the arc-shaped notch 108 are both located in the middle of their respective edges and are semi-circular arc-shaped, while the single-slit cut 106 is "L"-shaped.
[0027] The center of the edge of the snap-fit plate 104 opposite to the outer cover 102 is an arc-shaped flange, and the two sides of the arc-shaped flange to the two sides of the snap-fit plate 104 are two symmetrical arc-shaped edges. When the arc-shaped snap 105 of the snap-fit plate 104 is inserted into the convex snap hole 103 of the inner cover 101 and locked, the snap-fit plate 104 can be horizontally covered on the outer cover 102, or it can be folded up to form a paper display surface, which can be used as a handle for moving the packaging box. In this embodiment, the arc-shaped flange is semi-circular.
[0028] Both sides of the top opening are connected to hinged covers 107 of the same shape. When the top opening is closed, the hinged covers 107 are located below the inner cover 101, which enhances the strength of the top of the packaging box. In this embodiment, the hinged covers 107 are semi-circular.
[0029] like Figure 5 As shown, the box body 100 is formed by folding and connecting single sheets of cardboard. The box body also includes sides, which include a front side panel 200, a rear side panel 201, a left side panel 202, and a right side panel 203. The left and right edges of the front side panel 200 are connected to the left side panel 202 and the right side panel 203, respectively. The left edge of the left side panel 202 is connected to the rear side panel 201. The free edge of the rear side panel 201 is connected to the first adhesive plate 204. The front side panel 200, rear side panel 201, left side panel 202, and right side panel 203 are all of equal height and their top edges are flush.
[0030] The box body 100 also includes a bottom, which includes an outer bottom plate 300, an inner bottom plate 301, a left bottom plate 302, and a right bottom plate 303. The lower edges of the front side plate 200, rear side plate 201, left side plate 202, and right side plate 203 are respectively connected to the outer bottom plate 300, inner bottom plate 301, left bottom plate 302, and right bottom plate 303, and the free edge of the outer bottom plate 300 is connected to the second adhesive plate 304. After folding to form the box, the front side panel 200, rear side panel 201, left side panel 202, and right side panel 203 are arranged in a circle, and the outer side of the first adhesive plate 204 is connected to the inner side of the free edge of the right side panel 203 with glue or staples. The inner bottom panel 301, left bottom panel 302, and right bottom panel 303 are folded and placed on top of the outer bottom panel 300. Then, the inner side of the second adhesive plate 304 is connected to the outer side of the lower edge of the rear side panel 201 with glue or staples, thus forming a closed box. Figure 1 The packaging box shown.
[0031] Both the left side panel 202 and the right side panel 203 have openings 109. This ensures ventilation for the items inside the packaging box, meeting the ventilation requirements of some items. It also enhances the display effect, as the openings act as display windows, allowing consumers to preview the items inside without opening the box, thus increasing the packaging's visual appeal and attractiveness. The openings 109 can be circular, elliptical, angular, rhomboid, etc., and are not listed here. In this embodiment, the openings 109 are located at the center of the left side panel 202 and the right side panel 203 and are circular.
[0032] When packaging items, first place the items inside the box, then fold the flaps 107 on both sides of the top opening inwards, and then close the inner cover 101. At this point, the box should look like... Figure 2 In the state shown, the buckle plate 104 connected to the outer cover 102 is folded up and the outer cover 102 is closed. Finally, the arc buckle 105 is inserted into the convex buckle hole 103 and pushed into the narrow part of the convex buckle hole 103 so that the two protruding shoulders 110 inside the convex buckle hole 103 are just embedded in the single-slit cuts 106 at both ends of the arc buckle 105, thereby completing the locking of the packaging box. The packaging is now complete.
[0033] After packaging, the snap-on plate 104, in its locked state, can smoothly cover the outer surface of the outer cover 102, as shown below. Figure 3 As shown, this allows multiple packaging boxes to be stacked for placement and transfer. When the packaging boxes need to be moved, the snap-on plate 104 can be folded up to form a paper display surface, as shown. Figure 4 As shown, at this point, the packaging box can be moved by lifting the paper, and the lock will remain firmly engaged, preventing the packaging box from tilting or even tipping over.
[0034] As can be seen from the technical solution of this utility model, firstly, by setting a convex latching hole 103 in the inner cover 101 and a latching plate 104 connecting the outer cover 102, when the top opening of the packaging box is closed, the arc-shaped latch 104 of the latching plate 104 is inserted into the convex latching hole 103, and the two protruding shoulders 110 inside the convex latching hole 103 are precisely embedded in the single-slit cuts 106 at both ends of the arc-shaped latch 105, thereby achieving locking, anti-theft and confidentiality, and good packaging effect. Secondly, after the latching plate 104 is folded up, it can serve as both a display surface and a handle, which enhances the display effect of the packaging box and facilitates the movement of the packaging box, resulting in good usability. Thirdly, the packaging box is made of a single sheet of cardboard folded and connected, which is simple to operate, has high packaging efficiency, low cost, and is easy to mass-produce.
[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
