[0047] In order to better understand the technical solution of the present utility model, the embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0048] like Figure 1 As shown, Figure 1 This is a schematic diagram of an expanded product packaging box provided in an embodiment of the present application, wherein the product packaging box includes a box cover 100, a box body 200 and a box bottom 300 that are integrally arranged.

[0049] Among them, the box body 200 includes a first connecting plate 210, a second connecting plate 220, a third connecting plate 230 and a fourth connecting plate 240 which are connected end to end in sequence. One end of the first connecting plate 210 is connected to an extension plate 250, and the extension plate 250 is fixedly connected to the fourth connecting plate 240 by glue or special nails for paper boxes to form a circumferentially closed box body 200.

[0050] Secondly, the box cover 100 includes a first plate 110, a cover plate 120 and two dustproof plates 130. The first plate 110 is connected to the top of the first connecting plate 210, one dustproof plate 130 is connected to the top of the second connecting plate 220, the cover plate 120 is connected to the top of the third connecting plate 230, and another dustproof plate 130 is connected to the top of the fourth connecting plate 240. When closing the packaging box, the first plate 110 is covered on the top of the two dustproof plates 130, and the cover plate 120 is covered on the top of the first plate 110. The two dustproof plates 130 are used to block the gaps that cannot be covered after the first plate 110 and the cover plate 120 are covered, so as to prevent insects, dust or other debris from entering the packaging box.

[0051] Combination Figure 1 and Figure 2 As shown, the cover plate 120 includes a first side 123 and a second side 124. In this embodiment, the first side 123 and the second side 124 are adjacent and their respective extension directions intersect on the same plane, and can be further arranged to be perpendicular. The second side 124 is provided with an inserting tongue 121, and the first plate 110 has a socket 111 for the inserting tongue 121 to buckle into, see Figure 3 The insert tongue 121 includes a first tongue piece 1211, a second tongue piece 1212 and a third tongue piece 1213. A first fold line 121a is provided between the first tongue piece 1211 and the cover plate 120. The first tongue piece 1211 is bent around the first fold line 121a. A second fold line 121b is provided between the second tongue piece 1212 and the first tongue piece 1211. The second tongue piece 1212 is bent around the second fold line 121b. A third fold line 121c is provided between the third tongue piece 1213 and the second tongue piece 1212. The third tongue piece 1213 is bent around the third fold line 121c. The first fold line 121a is perpendicular to the second fold line 121b, and the third fold line 121c is parallel to the second fold line 121b. By providing the fold lines, the tongue pieces have a certain deformation ability and are not easily damaged. The inserting tongue 121 is folded in half along the second fold line 121b and the third fold line 121c to form a stacked structure that can be inserted into the socket 111. The structure is then buckled back into the socket 111 along the first fold line 121a. At this time, the second tongue piece 1212 and the third tongue piece 1213 are restored under the elastic restoring ability of their own structure to release the stacked state, so that the stretched structure is locked inside the socket 111 and cannot be pulled out through the socket 111, thereby achieving stable closure of the cover 120.

[0052] Combination Figure 1 and Figure 4As shown, the cover plate 120 is provided with a tear line 122, the starting point of the tear line 122 is set on the second edge 124, close to the second fold line 121b of the inserting tongue 121 and located on the side of the inserting tongue 121 away from the first edge 123, and the tear line 122 extends from the starting point to the first edge 123. Such a configuration makes it possible for the tear line 122 to form a certain angle with the second side 124, and the tear line 122 is tilted on the cover plate 120. At the same time, since the starting point of the tear line 122 is close to the plug tongue 121 and backed by the first side 123, when removing the packaging box, the hand will grab the cover plate 120 from the second side 124 and at a position on the side away from the first side 123 and open it toward the opposite side of the second side 124. Since the starting point of the tear line 122 is located between the plug tongue 121 and the grabbing position at this time, and since the plug tongue 121 is relatively fixed relative to the box body 200, it can be known from stress analysis that the starting point is easy to be torn, and the packaging box can be opened smoothly along the tear line structure tilted toward the first side 123, ensuring that the overall structure of the packaging box is stable while also having easy disassembly characteristics. Among them, the angle formed by the tear line 122 and the second side 124 of the cover plate 120 can preferably range from 20° to 35°, making it easier to be torn. When the inserting tongue 121 of the cover plate 120 is inserted into the slot of the first plate 110 , the top of the packaging box remains flat without warping.

[0053] In one embodiment of the present invention, the cover plate 120 is provided with a third side 125 different from the first side 123. Figure 1 The third side 125 and the first side 123 are respectively arranged on the opposite sides of the second side 124, and the tear line 122 includes a first tear line 122a and a second tear line 122b that are arranged opposite to each other. The starting points of the first tear line 122a and the second tear line 122b are both arranged on the second side 124 of the cover plate 120. The starting point of the first tear line 122a is close to the tongue 121 and is located on the side of the tongue 121 away from the first edge 123, and the first tear line 122a extends from the starting point of the first tear line 122a to the first edge 123, so that the first tear line 122a is inclined toward the first edge 123 on the cover plate 120, and the starting point of the second tear line 122b is close to the tongue 121 and is located on the side of the tongue 121 away from the third edge 125, and the second tear line 122b extends from the starting point of the second tear line 122b to the third edge 125, so that the second tear line 122b is inclined toward the third edge 125 on the cover plate 120. The first tear line 122a and the second tear line 122b are arranged opposite to each other and are located at the inner side of the tongue 121, so that force can be applied between the two tear lines to quickly and easily tear the cover plate structure.

[0054] In addition, the cover plate 120 is provided with a gripping portion 1221, which is arc-shaped and is arranged between the starting point of the first tear line 122a and the starting point of the second tear line 122b. In this embodiment, it is arranged in the middle area of ​​the second edge 124, and the inserting tongue 121 is arranged on both sides of the middle area. When the user opens the package, the gripping portion 1221 of the upper cover is gripped to apply external force to facilitate the opening of the tear line.

At this time, the force application part is located between the first inserting tongue 12a and the second inserting tongue 12b, because the two sides of the grasping part 1221 in the middle area are fixed by the first inserting tongue 12a and the second inserting tongue 12b, the stress concentration point of the grasping part 1221 during tearing is located at the starting point of the two easy tearing lines and is quickly torn along the easy tearing lines during the tearing process, so that the packaging box of the product is easy to remove.

[0056] The first plug tongue 12a extends in a direction away from the first edge 123, and the second plug tongue 12b extends in a direction away from the second edge 123, so that after the first plug tongue 12a and the second plug tongue 12b are inserted into the corresponding socket 111, the parts in the extending direction (the second tongue piece 1212 and the third tongue piece 1213) thereof abut against the middle area between the two plug tongues, so that the untorn area of ​​the cover plate 120 is stably fixed on the box cover 100 to match the action direction and action area of ​​the grabbing portion 1221.

[0057] Figure 1 As shown, two sockets 111 are provided and are located at relative positions of the first plug tongue 12a and the second plug tongue 12b after the product packaging box is folded, so as to allow the first plug tongue 12a and the second plug tongue 12b to be inserted respectively, wherein the socket 111 includes a first opening area 1111 for the first tongue piece 1211 to pass through and a second opening area 1112 for the second tongue piece 1212 and the third tongue piece 1213 to pass through, the first opening area 1111 is connected to the second opening area 1112, and the long side of the second opening area 1112 is smaller than the long side of the first opening area 1111, so as to reduce the size of the socket 111.

[0058] like Figure 1As shown, the box bottom 300 includes a first bottom plate 310, a second bottom plate 320 and two side bottom plates 330 which are overlapped and connected to form a hook bottom structure, the first bottom plate 310 is connected to the bottom end of the first connecting plate 210, one side bottom plate 330 is connected to the bottom end of the second connecting plate 220, the second bottom plate 320 is connected to the bottom end of the third connecting plate 230, and the other side bottom plate 330 is connected to the bottom end of the fourth connecting plate 240.

[0059] Specifically, first corner cutouts 311 are provided at both ends of the first bottom plate 310, first plug-ins 331 are provided on both side bottom plates 330, and the first plug-ins 331 cooperate with the first corner cutouts 311 so that the two side bottom plates 330 are stacked on the first bottom plate 310, second corner cutouts 332 are provided on both side bottom plates 330, and second plug-ins 321 are provided on both ends of the second bottom plate 320, and the second plug-ins 321 cooperate with the second corner cutouts 332 so that the second bottom plate 320 is stacked on the two side bottom plates 330.

[0060] The first bottom plate 310 has at least one protrusion, and the second bottom plate 320 has at least one recess matched with the protrusion, wherein the protrusion is provided with an extension portion, and after the first bottom plate 310 and the second bottom plate 320 are engaged with each other, the extension portion is superimposed on the second bottom plate 320.
