Abstract
Description
Technical Field
[0001] This application relates to the field of packaging boxes, and more particularly to a folding packaging box. Background Technology
[0002] Most existing packaging boxes are made of corrugated board or PP honeycomb board. Among them, packaging boxes made of PP honeycomb board have high strength when folded and can withstand strong impacts.
[0003] like Figure 1 As shown, the PP honeycomb panel consists of three layers: a surface layer 101, a honeycomb core layer 102, and a bottom layer 103. The honeycomb core layer 102 is located between the surface layer 101 and the bottom layer 103. The surface layer 101 and the bottom layer 103 are typically thin polypropylene plastics. The honeycomb core layer 102 provides high rigidity and lightweight support for the panel. When the PP honeycomb panel is thick, it is difficult to bend. This makes the manufacture of packaging boxes more difficult. Therefore, as... Figure 1 As shown in the intermediate drawing, in the prior art, creases 104 are cut at the positions of the surface layer 101 and the honeycomb core layer 102. When making the packaging box, the panel is bent at the crease 104 position, which solves the problem that PP honeycomb panels are difficult to bend.
[0004] After the PP honeycomb panel is bent along the crease, an angle is formed between the two side panels of the packaging box, and the two side panels of the packaging box are connected by the bottom layer 103 of the PP honeycomb panel. When the packaging box is impacted from the outside, the side panels of the packaging box will be pushed towards the inner cavity of the packaging box, which will cause the bottom layer 103 and the honeycomb core layer 102 to tear. In severe cases, it will cause damage to the packaging box and the goods inside.
[0005] Therefore, how to design a folding packaging box that reduces the risk of tearing between the bottom layer and the honeycomb core layer has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0006] This application provides a folding packaging box to at least solve the above-mentioned technical problems existing in the prior art.
[0007] A folding packaging box is provided, including a honeycomb panel, which is provided with a top layer, a honeycomb core layer and a bottom layer in sequence. The honeycomb panel is provided with a number of creases that penetrate the top layer and the honeycomb core layer along a first direction. The honeycomb panel is bent along the creases to form a box body with a ring-shaped closed shape. It also includes a number of limiting members, which are distributed on both sides of the creases along the first direction.
[0008] The positioning mechanism penetrates the honeycomb panel to fix the limiting component on the surface layer, and there is an insertion gap between the limiting component and the surface layer;
[0009] The reinforcing corner strip is inserted into the insertion gap on both sides of the crease along the first direction.
[0010] In one embodiment, the limiting member includes a limiting stop, an extension stop, and a positioning stop connected end to end in sequence. The limiting stop and the positioning stop are both perpendicular to the extension stop. The positioning stop is fixedly connected to the honeycomb panel through a positioning mechanism. After the limiting member is installed, the plane where the limiting stop is located is parallel to the plane where the honeycomb panel is located.
[0011] In one embodiment, the cross-section of the limiting member is Z-shaped.
[0012] In one embodiment, the positioning mechanism includes a positioning bolt and a positioning nut. A through hole is provided on the positioning stop. The positioning bolt passes through the honeycomb plate and the through hole in sequence. The positioning bolt and the positioning nut are threadedly connected.
[0013] In one embodiment, the cross-section of the reinforcing corner strip is L-shaped.
[0014] In one embodiment, the honeycomb panel is provided with three creases arranged along a first direction, and the honeycomb panel is provided with a first side plate, a second side plate, a third side plate and a fourth side plate connected in sequence, and also includes a positioning member for detachably fixing the first side plate and the fourth side plate.
[0015] In one embodiment, the positioning element includes hook and loop fasteners and loop fasteners, one of which is fixed to the first side plate and the other is fixed to the fourth side plate.
[0016] In one embodiment, the device further includes a bottom sealing plate and a top cover plate. The bottom sealing plate is riveted to and bent to form the bottom of the box. The other end of the bottom sealing plate is detachably connected to the first side plate via a first connector. One end of the top cover plate is riveted to and bent to form the top cover of the box. The top cover plate is detachably connected to the first side plate via a second connector.
[0017] In one embodiment, elastic pads are provided on the inner wall of the box, the inner side of the top cover, and the inner side of the bottom cover.
[0018] In one embodiment, the outer side wall of the box is provided with a handle.
[0019] Compared with the prior art, the folding packaging box of this application has the following advantages:
[0020] This application utilizes creases on the honeycomb panel to bend it into a closed ring-shaped box, laying the foundation for the formation of the packaging box. The creases solve the problem of the honeycomb panel being difficult to bend. A positioning mechanism penetrates the honeycomb panel and fixes the limiting component, thereby positioning the surface and bottom layers of the honeycomb panel on both sides of the crease, preventing the honeycomb core layer from tearing from the bottom layer, improving the strength of the packaging box, and enhancing its impact resistance. Reinforcing corner strips are inserted into the gaps formed between the limiting component and the surface layer on both sides of the crease. At this time, the adjacent side panels of the box are formed as a whole by the reinforcing corner strips. The reinforcing corner strips transfer the force on the side panels to the adjacent side, reducing the risk of relative movement between adjacent side panels, and further reducing the risk of tearing between the honeycomb core layer and the bottom layer.

[0040] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0041] This application improves packaging boxes made of PP honeycomb panels, solving the problems caused by the inconvenience of PP honeycomb panels in folding and the series of problems caused by folding.
[0042] Before introducing the technical solution of this invention, as follows: Figure 1 As shown in the upper middle drawing, the PP honeycomb panel includes a surface layer 101, a honeycomb core layer 102, and a bottom layer 103 arranged sequentially. The surface layer 101 and the bottom layer 103 are made of polypropylene plastic and can be bent. The honeycomb core layer 102 is honeycomb-shaped to improve the strength and support capacity of the PP honeycomb panel.
[0043] Because the honeycomb core layer 102 is relatively thick, when the PP honeycomb panel is bent directly, the innermost surface layer 101 and the honeycomb core layer 102 are subjected to compression deformation at the bending position, while the outermost bottom layer 103 is subjected to tension and is easily torn, thus causing the problem that the PP honeycomb panel is difficult to bend.
[0044] To solve this problem, such as Figure 1As shown in the middle drawing, a crease 104 is provided on the PP honeycomb board that penetrates the surface layer 101 and the honeycomb core layer 102. The cross-section of the crease is triangular. The material at the bending point of the PP honeycomb board is cut, leaving only the connection of the bottom layer 103. By bending the bottom layer 103 at the crease 104, the problem of the PP honeycomb board being difficult to bend is solved.
[0045] When the PP honeycomb panel is bent, as Figure 1 As shown in the bottom diagram, side plates are formed on both sides of the crease 104, and an angle is formed between the two side plates. When one side plate is subjected to a force applied in the direction of the surface layer 101, the two side plates will move relative to each other, which will cause the honeycomb core layer 102 to separate from the bottom layer 103, resulting in a decrease in the firmness of the enclosure 3.
[0046] To address the issue of the bottom layer 103 separating from the honeycomb core layer 102 after the PP honeycomb panel is bent, improvements were made to the packaging box formed by the PP honeycomb panel.
[0047] like Figure 2 As shown, in this embodiment, the box body 3 includes an opening that runs through the top and bottom. The box body 3 is formed by bending a honeycomb panel 2 to form a closed ring structure. The packaging box also includes a bottom sealing plate 91 disposed at the bottom of the box body 3 and a top cover plate 92 disposed at the top of the box body 3. The bottom sealing plate 91 is bent and the bottom opening of the box body 3 is sealed by a first connector 93. The top cover plate 92 is bent and the top opening of the box body 3 is sealed by a second connector 94, thereby forming a packaging box.
[0048] To achieve the formation of the housing 3, in this embodiment, as follows: Figure 3 As shown, it includes a honeycomb panel 2. The structure of the honeycomb panel 2 in this embodiment is consistent with the structure of the PP honeycomb panel in the prior art. The honeycomb panel 2 is provided with a plurality of creases 104 arranged along the first direction X. It is worth noting that in this embodiment, there are three creases 104 arranged along the second direction Y. The first direction X refers to the height direction along the box body 3.
[0049] Among them, three creases 104 separate the honeycomb panel 2 into a first side panel 21, a second side panel 22, a third side panel 23 and a fourth side panel 24 that are connected in sequence. The creases 104 penetrate the surface layer 101 and the honeycomb core layer 102 of the honeycomb panel 2. At this time, the first side panel 21, the second side panel 22, the third side panel 23 and the fourth side panel 24 are connected through the bottom layer 103.
[0050] When the honeycomb panel 2 is bent around the crease 104 to form a closed ring structure, it also includes a positioning component 8 for fixing the box body 3.
[0051] Specifically, such as Figure 2As shown, the positioning component 8 includes hook-and-loop fastener 81 and rough-surface hook-and-loop fastener 82. The hook-and-loop fastener 81 is fixedly installed on the first side plate 21 by rivets, and the rough-surface hook-and-loop fastener 82 is fixedly installed on the fourth side plate 24 by rivets. When the first side plate 21 and the fourth side plate 24 are closed to form a ring, the rough-surface hook-and-loop fastener 82 is attached to the hook-and-loop fastener 81, thereby realizing the connection between the end of the box 3.
[0052] Furthermore, such as Figure 2 and Figure 3 As shown, the side of the fourth side panel 24 away from the third side panel 23 is cut to retain the original bottom layer 103 structure. When the honeycomb panel 2 surrounds the box 3, the bottom layer 103 on the fourth side panel 24 wraps around the first side panel 21, thereby sealing the gap between the first side panel 21 and the fourth side panel 24 and enhancing the sealing of the box 3.
[0053] The positioning component 8 has a detachable structure. When the packaging box needs to be folded for storage, simply tear apart the hook and loop fastener 81 and the rough hook and loop fastener 82.
[0054] To address the issue of adjacent side panels moving into the inner cavity of the housing 3, causing tearing between the honeycomb core layer 102 and the bottom layer 103, in this embodiment, as follows... Figure 4 and Figure 5 As shown, it also includes several limiting members 4 arranged along the first direction X, wherein the limiting members 4 are distributed on both sides of the crease 104, and the limiting members 4 are fixedly installed on the honeycomb plate 2 by the positioning mechanism 5, forming an insertion gap 6 between the limiting members 4 and the honeycomb plate 2. It also includes reinforcing corner strips 7. When the honeycomb plate 2 is bent around the crease 104 at an angle, the reinforcing corner strips 7 are simultaneously inserted into the insertion gap 6 formed between the limiting members 4 on both sides of the crease 104 and the honeycomb plate 2 along the first direction X.
[0055] The reinforcing corner strip 7 has an L-shaped cross-section, which restricts the movement of adjacent side panels toward the inner cavity of the housing 3. This strengthens the housing 3's ability to deform under external impacts and reduces the risk of tearing between the bottom layer 103 and the honeycomb core layer 102.
[0056] like Figure 6 As shown, the limiting member 4 includes a limiting stop 41, an extension stop 42, and a positioning stop 43. The limiting stop 41, the extension stop 42, and the positioning stop 43 are connected in sequence. The limiting stop 41 and the positioning stop 43 are both perpendicular to the extension stop 42. The limiting stop 41 and the positioning stop 43 are parallel to each other. The cross-section of the limiting member 4 is similar to a Z-shape.
[0057] The positioning baffle 43 is attached to the inner surface 101 of the honeycomb panel 2, and the positioning mechanism 5 is used to fix the limiting member 4 to the honeycomb panel 2.
[0058] like Figure 5 and Figure 6 As shown, the positioning mechanism 5 includes a positioning bolt 51 and a positioning nut 52. A through hole 431 is provided on the positioning stop 43. The positioning bolt 51 passes through the honeycomb plate 2 and the through hole 431 and is threadedly connected to the positioning nut 52, thereby realizing the fixation of the limiting member 4.
[0059] It is worth noting that, since the positioning bolts 51 penetrate the honeycomb panel 2 and are located on both sides of the crease 104, the positioning bolts 51 further fix the bottom layer 103 and the surface layer 101 on both sides of the honeycomb panel 2 on the crease 104, reducing the risk of tearing between the bottom layer 103 and the honeycomb core layer 102.
[0060] like Figure 7 As shown, the bottom sealing plate 91 is fixed to the third side plate 23 by rivets. After the bottom sealing plate 91 is bent, it seals the bottom opening of the box 3. Then it is connected to the first side plate 21 by the first connector 93, thereby realizing the fixation of the bottom sealing plate 91.
[0061] Specifically, the first connector 93 includes a strap and a positioning rope. The strap is fixedly installed on the bottom sealing plate 91, and the rope is fixedly installed on the outer wall of the first side plate 21. The strap and the rope are knotted to fix the bottom sealing plate 91.
[0062] like Figure 7 As shown, the top cover 92 is fixedly installed on the third side plate 23 by rivets. The top cover 92 is bent to block the top opening of the box 3. The top cover 92 is fixedly connected to the first side plate 21 by the second connector 94.
[0063] Specifically, the second connector 94 is fixed with Velcro, which includes hook Velcro 81 and loop Velcro 82.
[0064] A handle 10 is fixedly installed on the outer side wall of the box body 3, which can be used to assist in moving the packaging box.
[0065] Furthermore, such as Figure 3 As shown, elastic pads 95 are provided on the inner walls of the box 3, the bottom sealing plate 91, and the inner side of the top cover plate 92. When the goods are placed in the inner cavity of the box, the elastic pads 95 abut against the goods, thereby protecting the goods.
[0066] It is worth noting that the elastic pad 95 here can be a rubber pad or a flannel pearl cotton pad.
[0067] It is worth noting that the top cover 92 and the bottom cover 91 are made of bendable plastic.
[0068] Furthermore, the PP honeycomb panel in this application has a thickness of 5mm and a density of 1600g / m³. 2 .
