Description

Technical Field

[0001] This utility model relates to a blister packaging box, and more particularly to a packaging box structure. Background Technology

[0002] Currently, all blister packaging boxes sold on the market need to be packed and transported to users after production. These boxes are typically stacked one by one during packing to save space and maximize the number of boxes that can fit into a carton. However, due to the presence of interlocking or recessed structural components and the boxes' thinness, forcibly stacking them can cause them to jam together. While this increases the number of boxes per carton, it requires manual and rough handling when handling them individually, which can easily damage the boxes. Loosely stacking the boxes reduces the number of boxes per carton and can also lead to problems with separation due to static electricity. Summary of the Invention

[0003] The purpose of this utility model is to provide a packaging box structure, and the technical problem to be solved is to increase the number of packaging boxes packed in a single carton.

[0004] To solve the above problems, the present invention adopts the following technical solution: a packaging box structure, including a body, the body including a bottom box and a lid connected by a connecting part, the bottom box is provided with a first folded edge bent outward, the lid is provided with a second folded edge bent outward, the bottom box is provided with a first convex recess on its four edges, the lid is provided with a second convex recess on its four edges, the first recess and the second recess both serve as first stacking positions, when the bodies are stacked on each other, the first recesses on two adjacent bodies overlap each other, and the second recesses overlap each other.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 , Figure 2 , Figure 5 as well as Figure 8 and Figure 9 As shown, this utility model discloses a packaging box structure. The packaging box is a blister packaging box with a sheet thickness of 0.2-0.4mm. The packaging box structure includes a body, which includes a bottom box 1 and a lid 3 connected by a connecting part 2. The body is a rectangular box. Both the bottom box 1 and the lid 3 have internal cavities. A first folded edge 4 is provided on the upper edge of the bottom box 1, with a gap between the first folded edge 4 and the outer surface of the bottom box 1. A second folded edge 5 is provided on the opening edge of the lid 3, with a gap between the second folded edge 5 and the outer surface of the lid 3. In this utility model, the lid 3 is a disc-shaped structure with a certain depth. A first protruding recess 6 is provided on the four edges of the upper end of the bottom box 1. On the opposite side of the lid 3 and the bottom box 1 ( Figure 5 The upper part of the packaging box has a second protruding recess 7 on its four edges. The first recess 6 and the second recess 7 are both used as the first stacking position. When the main body is stacked, the first recess 6 on the two adjacent main bodies overlaps and the second recess 7 overlaps. The first recess 6 and the second recess 7 are used to limit the distance between the two adjacent main bodies after stacking, so as to prevent the two main bodies from being stacked too tightly, while compressing the overall height of the packaging box after stacking, and increasing the packing quantity of a single carton.

[0025] Of course, the above structure also avoids the problem of difficulty in separation caused by overly tight stacking.

[0026] In this utility model, the depth G of the first recess 6 and the second recess 7 is 4-5mm. The depth here refers to the distance between the top edge of the bottom box 1 and the bottom of the first recess 6, and the distance between the edge of the cover 3 opposite to the bottom box 1 and the bottom of the second recess 7.

[0027] like Figure 1 As shown, the peripheral walls of the first pit 6 and the second pit 7 are arc-shaped.

[0028] In this utility model, since the packaging box is a blister packaging box, after the first recess 6 and the second recess 7 are set, they both protrude from the outer surface of the bottom box 1 and the lid 3.

[0029] In this year's utility model, such as Figure 1 As shown, the first recesses 6 are distributed at the four corners of the bottom box 1, and are arranged opposite each other. The second recesses 7 are distributed at the four corners of the cover 1, and are arranged in a staggered manner.

[0030] In this invention, a second stacking position can also be provided to further prevent damage to other positions besides the first and / or second recesses due to compression, specifically, as shown below. Figure 6 As shown, the first folded edge 4 includes a first surface 41, a second surface 42, and a third surface 43. The first surface 41 is integrally connected to the bottom box 1, and there is an angle between the first surface 41 and the top of the body wall of the bottom box 1. The second surface 42 is connected to the first surface 41 and has an angle, and the second surface 42 is connected to the third surface 43 and has an angle. The specific degree of the angle can be determined according to the specific size of the packaging box, and is not specifically limited here. A recessed groove 8 is provided on the second surface 42, and the groove 8 protrudes from the first space 101 enclosed by the bottom box 1, the first surface 41, and the second surface 42.

[0031] like Figure 7 As shown, the inner wall of the lid 3 is provided with a protruding buckle 9. The buckle 9 is located near the end of the inner wall of the lid 3 adjacent to the bottom shell 1, so that when the lid 3 and the bottom box 1 are closed, the buckle 9 at the corresponding position can engage with the groove 8. When the bodies are stacked, the inner surface of the groove 8 and the outer surface of the buckle 9 form a second stacking position. The bottom of the inner surface of the groove 8 of the upper body abuts against the first surface 41, and the lower edge of the outer surface of the lid 3 abuts against the buckle 9. The stacking mentioned in this utility model refers to the packaging boxes being unfolded and stacked together (i.e., as shown in the figure). Figure 2 As shown, due to the limitation of the first stacking position formed by the first and second recesses and the second stacking position formed by the groove and the buckle, the packaging boxes are not too tightly stacked. This allows them to be easily separated during use. The size of the first stacking position is defined to ensure that the use of the packaging boxes is not affected. The maximum number of boxes that can be packed in a single box is also defined. The aforementioned "not affected during use" can be understood as not being easy to separate or causing damage when forcibly separated.

[0032] In this utility model, such as Figure 6As shown, the depth H of the groove 8 is 1.7-2.4mm, and the height I is 2.6-3.5mm. These dimensions are the net internal dimensions of the groove 8, and its length can be set as needed, without specific limitation. The height O from the first surface 41 to the lower end of the groove wall of the groove 8 is between 4-5mm. Of course, the groove wall 81 at the upper end of the groove 8 can also be set as an inclined surface from the groove opening of the groove 8 toward the groove wall at the opposite end of the groove opening, so that the protruding buckle 9 can enter the groove 8 more easily, and it is also convenient to separate the protruding buckle 9 from the groove 8. When the groove wall 81 is an inclined surface, the included angle P between it and the groove wall at the opposite end of the groove opening of the groove 8 is at least 125°; the height J of the groove wall at the opposite end of the groove opening of the groove 8 is between 1.5-2.2mm.

[0033] like Figure 6 As shown, in this utility model, the second surface 42 is a slope, so that the upper groove edge and the lower groove edge of the groove 8 are misaligned, so that the upper groove of the groove 8 forms an avoidance part, making it easier to stack the packaging boxes. At the same time, the slope can also play a guiding role, so that the packaging boxes on the top can be stacked smoothly downwards.

[0034] like Figure 6 As shown, the end where the first surface 41 is connected to the second surface 42 can be set as an inclined surface, which can be further used to guide the protruding buckle 9 into the groove 8, and at the same time further improve the guiding effect during stacking.

[0035] like Figure 8 As shown, a recessed clearance 10 is provided on the lower edge of the outer surface of the lid 3, located at the protrusion 9, to allow for clearance of the protrusion 9 of the upper packaging box during stacking. In this invention, the clearance 10 may be provided only at the positions of some protrusions 9, such as... Figure 8 As shown, assuming that the cover 3 has six protrusions 9, four of which are respectively set on the two sides of the cover 3 opposite to the connecting part 2, and the other two are set on the other two sides of the cover 3 away from the connecting part 2. The groove 8 is set in the corresponding position. Then, the two protrusions 9 adjacent to the connecting part 2 are provided with a clearance position 10, while the protrusions 9 in other positions are not provided with a clearance position 10, in order to make it easier to separate the cover 3.

[0036] like Figure 7As shown, in this utility model, the second folded edge 5 includes a fourth surface 51, a fifth surface 52, and a sixth surface 53. The fourth surface 51 is integrally connected to the cover 3, and there is an angle between the fourth surface 51 and the upper edge of the cover 3. The fifth surface 52 is connected to the fourth surface 51 and has an angle, and the fifth surface 52 is connected to the sixth surface 53 and has an angle. In this utility model, the specific degree of the angle can be determined according to the specific size of the packaging box, and is not specifically limited here. It is only necessary to ensure that it can be adapted and connected to the bottom box 1. The second space 102 enclosed by the upper part of the outer surface of the cover 3, the fourth surface 51, and the fifth surface 52 is used to accommodate part of the structure at the corresponding position of the packaging box below.

[0037] like Figure 7 As shown, the protruding length K of the buckle 9 is 1.5-2.1mm, and the height L is 2.1-2.7mm. The dimensions here are the net dimensions of the buckle 9. Its length can be set as needed and is not specifically limited here. It just needs to match the length of the groove 8. The height Q between the fourth surface 51 and the lower end of the buckle 9 is 6.7-7.3mm. In this utility model, the cross-section of the buckle 9 is trapezoidal, wherein the angle M between the outer surface of the upper inclined surface and the top surface is at least 55°, and the angle N between the outer surface of the lower inclined surface and the top surface is at least 60°.

[0038] In this utility model, the connecting part 2 is integrally connected to the sixth surface 53 and the third surface 43 respectively, so that the top of the bottom box 1 and the end of the cover 3 opposite to the bottom box 1 are raised by one section. When the cover 3 is on the bottom box 1, the inner cavity wall of the cover 3 surrounds the second surface 42 at the end opposite to the bottom box 1.

[0039] like Figure 8 and Figure 9 As shown, in this utility model, the first recess 6 is formed on the first surface 41 and the body wall of the bottom box 1, and the second recess 7 is formed on the fourth surface 51 and the body wall of the cover 3.

[0040] This invention addresses the problem of packaging boxes being difficult to separate due to excessive stacking by setting a first stacking position and a second stacking position. In order to prevent this problem, existing packaging boxes are loosely stacked, but this results in a small number of boxes per carton. If the space in the carton is to be maximized, the structure of the packaging box may be damaged and rendered unusable due to excessive compaction. The first stacking position and the second stacking position not only solve this problem, but also maximize the number of boxes per carton.
