Abstract
Description
Technical Field
[0001] This utility model relates to the field of honeycomb paperboard, specifically to a honeycomb paperboard for packaging. Background Technology
[0002] Currently, honeycomb paperboard can dent and cushion impacts, so it is widely used in the packaging of home appliances, such as refrigerators. Refrigerators require honeycomb paperboard for packaging protection, especially the corners. Currently, two pieces of honeycomb paperboard are attached to the two perpendicular corners of the refrigerator and then connected with tape. This makes the packaging process cumbersome. Because the face paper of the honeycomb paperboard is quite hard, during transportation, it inevitably causes significant friction between the honeycomb paperboard and the refrigerator surface, which can easily scratch the refrigerator's paint. Therefore, existing honeycomb paperboard packaging technology needs improvement. Summary of the Invention
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a honeycomb cardboard for packaging, which facilitates packaging and provides better packaging protection.
[0004] The objective of this utility model is achieved through the following technical solution.
[0005] The honeycomb paperboard for packaging disclosed in this utility model includes a honeycomb paper core, an outer paper layer, and an inner paper layer. The honeycomb paper core is disposed between the outer paper layer and the inner paper layer. The inner paper layer is provided with a pearl cotton layer. It also includes a vertically arranged inward folding clearance groove, which passes through the pearl cotton layer, the inner paper layer, and the honeycomb paper core in the front-back direction.
[0006] Preferably, the pearl cotton layer is bonded to the inner paper layer.
[0007] Preferably, the outer paper layer is a kraft paper layer.
[0008] Preferably, the inner folding clearance groove is centered in the left-right direction.
[0009] Preferably, the thickness of the pearl cotton layer is set to 0.4 mm to 1.1 mm.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting an inner folding clearance groove that runs through the pearl cotton layer, the inner paper layer and the honeycomb paper core in the front and back direction, and the inner folding clearance groove is set vertically, the honeycomb paperboard for packaging can be switched between straight and right-angle shapes conveniently and quickly. This makes the honeycomb paperboard for packaging of this utility model more convenient for packaging and provides better packaging protection. Attached Figure Description

[0015] Labeling Explanation: Honeycomb paper core 1; Fold point 100; Outer paper layer 2; Connecting section 201; Inner paper layer 3; Pearl cotton layer 4; Inner fold clearance groove 5; First cardboard 10; Second cardboard 20; Refrigerator 99. Detailed Implementation
[0016] The present invention will now be further described with reference to the accompanying drawings.
[0017] The honeycomb cardboard for packaging of this utility model, such as Figure 1 and Figure 2 As shown, the package includes a honeycomb paper core 1, an outer paper layer 2, and an inner paper layer 3. The honeycomb paper core 1 is disposed between the outer paper layer 2 and the inner paper layer 3. The outer paper layer 2 and the inner paper layer 3 are respectively bonded to the honeycomb paper core 1. A pearl cotton layer 4 is provided on the inner paper layer 3. The pearl cotton layer 4 is made of polyethylene foam, so the pearl cotton layer 4 has good softness and elasticity. The honeycomb paperboard for packaging of this utility model also includes a vertically arranged inward folding clearance groove 5, such as... Figure 2 As shown, the inward folding clearance groove 5 penetrates the pearl cotton layer 4, the inner paper layer 3, and the honeycomb paper core 1 in the front-to-back direction. This means that the inward folding clearance groove 5 cuts through the pearl cotton layer 4, the inner paper layer 3, and the honeycomb paper core 1. Since the inward folding clearance groove 5 is vertically oriented, it also penetrates the pearl cotton layer 4, the inner paper layer 3, and the honeycomb paper core 1 in the up-down direction. However, the inward folding clearance groove 5 does not penetrate the outer paper layer 2; that is, the outer paper layer 2 remains intact. Figure 2 As shown, the honeycomb cardboard for packaging is thus separated into a first cardboard 10 and a second cardboard 20 by the inward folding clearance groove 5, and the first cardboard 10 and the second cardboard 20 are connected by a connecting section 201 (the connecting section 201 is part of the outer paper layer 2).
[0018] like Figure 4 As shown, when packaging the refrigerator 99, some of the honeycomb cardboard used in the packaging of this utility model is kept in a straight position and can be attached to the flat surface of the refrigerator 99, such as... Figure 3 and Figure 4 As shown, some of the honeycomb cardboard for packaging of this utility model can be folded into right-angle shapes, such as... Figure 2and Figure 3 As shown, the first cardboard 10 is swung 90° clockwise around the fold point 100 (i.e., folded inward at 90 degrees). Thus, the left end of the first cardboard 10 encroaches on the original position of the inward fold clearance groove 5. This can also be understood as the inward fold clearance groove 5 avoiding the left end of the first cardboard 10. The fold point 100 is specifically located at the rear left corner of the honeycomb paper core 1 of the first cardboard 10. Figure 4 As shown, the honeycomb cardboard folded into a right-angle shape can be wrapped around the four corners of the refrigerator 99, thus providing good protection for the refrigerator 99. Since the first cardboard 10 and the second cardboard 20, folded into a right-angle shape, are still connected by the connecting section 201, the honeycomb cardboard can maintain an integrated structure when wrapped around the four corners of the refrigerator 99. This prevents the first cardboard 10 and the second cardboard 20 from easily misaligning or separating, and avoids the need to use tape to connect the first cardboard 10 and the second cardboard 20 for airflow. This makes it more convenient for workers to handle the packaging of the refrigerator 99, and the switching between the straight and right-angle shapes of the honeycomb cardboard is also very convenient and quick. Since the left end of the first cardboard 10 encroaches on the original position of the inward folding clearance groove 5, as Figure 3 and Figure 4 As shown, this provides corresponding protection to the left end of the first cardboard 10 at the corner of the refrigerator 99. Figure 1 The honeycomb cardboard for packaging of this invention, as shown, can be stacked in a straight position when stored, thus reducing storage space. During transportation, the honeycomb cardboard, also in a straight position, is easy to stack inside the vehicle. Figure 3 As shown, since the pearl cotton layer 4 is located on the inner paper layer 3, when the honeycomb cardboard is folded into a right angle, the inner paper layer 3 is located inside the right angle, as shown. Figure 4 As shown, this allows the pearl cotton layer 4 to adhere to the surface of the refrigerator 99. Similarly, the straight-plate honeycomb cardboard also adheres the pearl cotton layer 4 to the surface of the refrigerator 99. Because the pearl cotton layer 4 (relative to the inner paper layer 3) is softer and more elastic, it prevents the pearl cotton layer 4 from scratching the paint on the surface of the refrigerator 99. As can be seen from the above, the honeycomb cardboard for packaging of this invention facilitates packaging and provides better protection.
[0019] like Figure 2 and Figure 3 As shown, the left end of the first cardboard 10 is adapted to occupy the original position of the inward folding clearance groove 5, so that the pearl cotton layer 4 at the left end of the first cardboard 10 can be attached to the right end face of the second cardboard 20, making the corner structure of the honeycomb cardboard folded into a right angle compact and stable. Thus, as Figure 2 As shown, the width dimension “W” of the inner fold clearance groove 5 should be slightly larger than the total thickness dimension “H” of the pearl cotton layer 4, the inner paper layer 3 and the honeycomb paper core 1. That is, the dimension “W” is 1 mm to 2 mm larger than the dimension “H”.
[0020] Furthermore, the pearl cotton layer 4 is bonded to the inner paper layer 3, thus simplifying the connection structure between the pearl cotton layer 4 and the inner paper layer 3 and avoiding the need to use tape to connect the periphery of the pearl cotton layer 4 to the honeycomb paperboard substrate (including the honeycomb paper core 1, the outer paper layer 2 and the inner paper layer 3).
[0021] Furthermore, the outer paper layer 2 is set as a kraft paper layer, that is to say, the outer paper layer 2 can be made of kraft paper. As mentioned above, the first cardboard 10 and the second cardboard 20 are connected by the connecting section 201. Kraft paper has the advantage of strong toughness, so the connecting section 201 can be avoided from breaking easily.
[0022] Furthermore, such as Figure 1 As shown, the inner folding clearance groove 5 is centered in the left and right direction, which helps to make the honeycomb paperboard for packaging have a symmetrical structure. When stacking straight honeycomb paperboard for packaging, the directional requirements of the honeycomb paperboard are reduced, which makes it easier to stack the honeycomb paperboard for packaging neatly.
[0023] Since the main function of the pearl cotton layer 4 is to separate the surface of the refrigerator 99 from the inner paper layer 3, the requirements for the strength and rigidity of the pearl cotton layer 4 are relatively low. Therefore, the thickness of the pearl cotton layer 4 is set to 0.4 mm to 1.1 mm. This means that the thickness of the pearl cotton layer 4 is relatively small, which can still meet the above-mentioned functions of the pearl cotton layer 4 and also helps to reduce costs.
