Description

Technical Field

[0001] This utility model belongs to the field of object packaging technology, and in particular relates to a packaging box. Background Technology

[0002] Packaging boxes are generally equipped with handles. Existing technology typically uses plastic handles, which are difficult to degrade. Furthermore, the plastic handles are integrated with the paper box body, leading to high costs in separating the paper box body and plastic handles during recycling. To address this, early developers created packaging boxes using paper handles, as shown in Chinese Utility Model Patent CN216762498U. This patent uses paper handles, where the lower surface of the handle is glued to the upper surface of the base plate, and the upper surface of the base plate is then glued to the lower surface of the inner wall of the box. However, this patented solution is not only costly and complex to manufacture, but also poses the risk of the handle pulling up the paper layer on the upper surface of the base plate.

[0003] In the early stages, the inventor also developed a packaging box with a structure similar to the one-piece easy-tear gift box disclosed in Chinese Utility Model Patent CN219791110U. The packaging box disclosed in this patent has a one-piece molded reinforcing paper box body. The reinforcing paper is formed by die-cutting. When in use, the reinforcing paper is folded 180 degrees inward along the pressure line between it and the box body, so that the handle mounting hole in the middle of the reinforcing paper is aligned with the handle mounting hole on the box body, thereby improving the support strength of the handle. However, this kind of reinforcing paper is cut from the box body. After cutting, the reinforcing paper needs to be movable and limited between the handle end face and the inner wall of the box, which makes the processing technology of this kind of packaging box complicated. Moreover, because the reinforcing paper is in a movable state, its protection effect on the handle hole is poor. Utility Model Content

[0004] The technical problem this invention aims to solve is that in the prior art, the reinforcing paper for packaging boxes is cut from the box body. After cutting, the reinforcing paper needs to be movable and limited between the handle end face and the inner wall of the box, which makes the processing of such packaging boxes complicated. Furthermore, because the reinforcing paper is in a movable state, its effect of protecting the handle hole is poor.

[0005] To solve the above problems, this utility model provides a packaging box, which includes a box body and a handle. The box body has a handle hole for limiting the handle, and the inner wall of the box body is adhered with reinforcing paper along the outer periphery of the handle hole.

[0006] In the above-described solution of this utility model, the reinforcing paper is not installed on the packaging box by cutting and separate installation, but is directly adhered to the inner wall of the box, and its position corresponds to the outer periphery of the handle hole. This eliminates the need for cutting and aligning the cut cardboard, greatly simplifying the production process. Because the reinforcing paper is tightly adhered to the inner wall of the box, its position is fixed and does not shift, preventing wear and tear caused by movement and the handle. Therefore, it can more effectively protect the handle hole from the impact or wear of the handle's pulling force and the weight of the packaging box and the packaged goods.

[0007] To ensure that the handle is securely installed on the box, as one option for the connection method between the handle and the box body in the above-mentioned packaging box, the handle has an upper surface and a lower surface; the end of the handle passes through the handle hole from the outside of the box body and enters the inside of the box body, so that the upper surface of the handle end is attached to the inner wall of the box body and / or the reinforcing paper.

[0008] In the above scheme, preferably, kraft paper is used as the reinforcing paper. Kraft paper has excellent tear resistance and high stiffness, and can withstand greater tensile and compressive forces without easily breaking.

[0009] To reduce the space occupied by the handle, one option is to have the handle bent at least once in its natural state. When the box needs to be lifted by the handle, it unfolds under gravity after being lifted.

[0010] To improve the tensile strength of the handle, in one alternative, the handle includes several reinforcing ropes along the length of the handle.

[0011] To improve the tensile strength of the handle, another alternative is to use laminated paper for the handle.

[0012] To improve the tensile strength of the handle, in another alternative, the reinforcing rope is located in the interlayer of the handle.

[0013] The technical advantages of this utility model are as follows:

[0014] In the packaging box provided by this utility model, the reinforcing paper is not set on the packaging box by cutting and separate installation, but is directly adhered to the inner wall of the box, and its position corresponds to the outer periphery of the handle hole. This eliminates the need for cutting and aligning the cut cardboard, greatly simplifying the production process. Because the reinforcing paper is tightly adhered to the inner wall of the box, its position is fixed and does not shift, avoiding wear and tear caused by movement and the handle. Therefore, it can more effectively protect the handle hole from the impact or wear of the handle's pulling force and the weight of the packaging box and the packaged goods.

[0015] In a preferred embodiment of this utility model, in order to reduce the space occupied by the handle, the handle is bent. In the scenario of stacking boxes, the handle is in a bent state. When it is necessary to use the handle to lift the box, the bent handle unfolds under the action of gravity after the handle is lifted.

[0016] In a preferred embodiment of this invention, to improve the tensile strength of the handle, the handle includes several reinforcing ropes along its length. In another embodiment, the handle is made of laminated paper. In yet another optional embodiment, the reinforcing ropes are located within the interlayer of the handle. The reinforcing ropes can improve the tensile strength of the handle along its length. Using laminated paper can also improve the tensile strength of the handle. Attached Figure Description

[0028] The lower surface will be combined with the attached Figures 1-7 The embodiments of the technical solution of this utility model are described in detail below. The following embodiments are only used to illustrate the technical solution of this utility model more clearly, and are therefore only examples, and should not be used to limit the protection scope of this utility model.

[0029] Figure 1 This illustration shows one embodiment of the packaging box of this utility model. The packaging box can protect the contents from physical damage such as collisions, compression, humidity, and dust during storage and transportation, and facilitates carrying the items, ensuring the product inside remains intact and is easy to transport. This packaging box can be used for packaging and transporting any item, such as a milk carton, apple carton, etc., and this utility model does not impose any limitations on this.

[0030] like Figures 1-5 The illustration shows a packaging box of the present invention. The packaging box includes a box body 1 and a handle 2. The box body 1 has a handle hole 11 for limiting the handle 2. Reinforcing paper 3 is adhered to the inner wall 101 of the box body around the handle hole 11.

[0031] For example, when the packaging weight is less than 10kg, the box body 1 is a paper box body, and the handle 2 is a paper handle. The handle 2 is a flat handle, and the handle hole 11 on the box body 1 is correspondingly flat and square. Reinforcing paper 3 is provided on the inner wall 101 of the box body 1 around the handle hole 11. The reinforcing paper 3 is bonded to the inner wall 101 with adhesive (not shown in the figure). To improve the bonding effect, the reinforcing paper 3 can optionally be bonded to the inner wall 101 by stamping. The tensile strength of the material used for the reinforcing paper 3 is higher than that of the cardboard. For example, if the cardboard is ordinary corrugated paper, the tensile strength of the reinforcing paper 3 is 80-120 g / m³. 2 The reinforcing paper 3 can be made of kraft paper or other high-strength, tough fiber paper. Kraft paper is preferred because it has excellent tear resistance and high rigidity, can withstand greater tensile and compressive forces without easily breaking, and is also relatively inexpensive.

[0032] When lifting the packaging box using handle 2, the contact area between handle 2 and the handle hole 11 on the box body 1 is small. Therefore, the force per unit area at the contact point between the box body 1 and handle 2 is particularly large. Thus, using a handle made of the same material as the cardboard box not only fails to completely solve the problem of cracking and failure around the handle hole 11 caused by the large force per unit area at the contact point between the packaging box and handle 2, but also, because existing reinforcing paper is cut from the box body, the cutting size needs to be considered, and the cut holes need to be aligned with the handle holes. Since the cut handle stack is not glued to the inner wall of the box, long-term pulling and moving of handle 2 can also cause this type of reinforcing paper to crack and fail at the opening. This invention uses paper with higher tear strength, glued to the box body at the handle hole, improving the tear strength at the handle hole 11.

[0033] In summary, the reinforcing paper 3 in the packaging box provided by this utility model is not set on the packaging box by cutting and separate installation, but is directly adhered to the inner wall 101 of the box, and its position corresponds to the outer periphery of the handle hole 11. This design makes the reinforcing paper an integral part of the box structure, eliminating the need for cutting and aligning the cut cardboard, which greatly simplifies the production process.

[0034] On the other hand, because the reinforcing paper 3 is tightly adhered to the inner wall of the box, its position is fixed and it is not easy to move. At the same time, this fixing method also avoids wear and tear on the reinforcing paper 3 due to movement and the handle 2. Therefore, it can more effectively protect the handle hole 11 from the impact or wear of the pulling force of the handle 2 and the weight of the packaging box and the packaged items.

[0035] In one implementation, such as Figures 1-5 The handle 2 has an upper surface 201 and a lower surface 202; the end of the handle 2 passes through the handle hole 11 from the outside of the box and enters the inside of the box, so that the upper surface 201 of the end of the handle 2 is attached to the inner wall 101 and / or the reinforcing paper 3 of the box 1.

[0036] It should be noted that the terms "upper surface" and "lower surface" are based on the orientation or positional relationship shown in the accompanying drawings or the positional relationship observed when the box is placed upright. They are used only for the convenience of describing this utility model and simplifying the description.

[0037] According to the packaging box of this utility model embodiment, the end of the handle 2 passes through the handle hole 11 from the outside of the box body and enters the inside of the box body. There are three ways to attach the handle: the first way is to attach the upper surface 201 of the handle end across the reinforcing paper 3 to the inner wall 101 of the box body 1; the second way is to attach the upper surface 201 of the handle end to the reinforcing paper 3; and the third way is to attach the upper surface of the handle end to both the inner wall of the box body and the reinforcing paper 3. The attachment method can be a stamping method. In the embodiment where the upper surface 201 of the handle end is attached to the inner wall 101 of the box body 1 and / or the reinforcing paper 3, after the handle 2 is fixed to the inner wall 101 of the box body 1, the end of the handle 2 extends outward.

[0038] In one implementation, such as Figures 1-5 When handle 2 is in its natural state, it has at least one bend.

[0039] It should be noted that "bending" in this utility model refers to possible states such as "bending" or "folding". Generally speaking, "bending" does not have a crease but forms a curved surface, while "folding" has a crease. However, whether it is "bending" or "folding", it will change the direction of the surface's extension.

[0040] The handle 2 is bent to reduce its space occupation. In a scenario where boxes 1 are stacked, the handle 2 is in a bent state. When the box needs to be lifted by the handle, it unfolds under the action of gravity. One or more bends can be used; for example, the handle can be folded in the middle, at one end, at both ends, or at any point on the handle. Generally, when there is only one bend, the lower surface 202 of the end of the handle 2 is adhered to the inner wall 101 of the box and / or the reinforcing paper 3. When there are two bends, the upper surface 201 of the end of the handle 2 is adhered to the inner wall 101 of the box and / or the reinforcing paper 3.

[0041] In one implementation, such as Figures 6-7 The handle 2 includes several reinforcing ropes 21 along its length. The reinforcing ropes 21 improve the tensile strength of the handle in the length direction. The reinforcing ropes can be made of high-strength fibers or high-density paper rope. Optionally, the reinforcing ropes 21 can be located on both sides of the handle 2 extending in the tensile direction, or multiple reinforcing ropes 21 can be arranged along the tensile direction of the handle 2. In one embodiment, the reinforcing ropes 21 are located within the interlayer of the handle 2.

[0042] In one embodiment, the handle 2 is made of laminated paper. Laminated paper is made by stacking multiple layers of paper, thereby increasing the tensile strength of the handle 2.

[0043] Finally, it should be noted that the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this utility model, are intended to cover non-exclusive inclusion. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise expressly specified. References to "embodiment" herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this utility model. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0044] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the technical terms such as "set", "equipped with", "installed", "connected", "fixed", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of this utility model can be understood according to the specific circumstances.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
