Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a convenient self-adhesive honeycomb paper structure. Background Technology

[0002] In the packaging industry, to meet the cushioning and protection needs of small and lightweight items, a honeycomb-shaped packaging paper that is cut and shaped has emerged. This packaging paper is based on a single sheet of tough paper, and with the help of a precision cutting process, intersecting cuts and folds are pre-set on the paper. No additional gluing steps are required. The flat paper can be naturally stretched into a honeycomb three-dimensional structure simply by pulling and stretching it manually or mechanically. The paper at the cuts supports each other to form a hollow grid and maintains its shape by its own tension.

[0003] This honeycomb-shaped packaging paper is flat when not in use, which can save a lot of storage and transportation space. When unfolded, the honeycomb structure has both cushioning and support properties, which can effectively provide shock protection for small and lightweight items such as jewelry, small cosmetic bottles, and stationery. Moreover, no glue is needed throughout the process, and it can be naturally degraded after disposal. It performs outstandingly in terms of ease of use and environmental protection, making it an ideal lightweight packaging choice to replace bubble wrap and ordinary waste paper.

[0004] However, existing honeycomb-shaped packaging paper still has certain drawbacks. Because its honeycomb structure is formed through cutting and bending, the honeycomb structure exhibits a gradient shape after bending. To achieve sufficient cushioning and shock absorption, multiple layers of wrapping are often required in actual use. However, due to the inherent characteristics of the honeycomb structure, adjacent layers of paper do not have sufficient binding force when they come into contact. Simultaneously, the honeycomb structure allows for air permeability between adjacent layers, making it difficult to secure them with adhesive. On the one hand, the adhesive lacks sufficient contact area; on the other hand, this air permeability allows adhesive to easily penetrate the innermost layer of product, causing contamination. Therefore, after multiple layers of wrapping are completed, if not promptly restrained by binding or other additional means, the paper can easily stretch open naturally, resulting in insufficient wrapping of the product, thus affecting the cushioning and protection effect and causing inconvenience in packaging operations. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0006] A convenient self-adhesive honeycomb paper structure includes a paper body with multiple staggered slits covering the paper body, and the slits having a wavy structure; there are fold lines between adjacent staggered slits on the paper body, and the slits are opened by the fold lines to form a honeycomb structure.

[0007] Preferably, the area between two adjacent staggered tangents on the paper body is a common segment, and there are two fold lines between two adjacent staggered tangents on the paper body, with the two fold lines located at both ends of the common segment; the area between the ends of two adjacent common segments on the paper body is a transition segment.

[0008] Preferably, the length of the shared segment is more than twice the width.

[0009] Preferably, the tangent has multiple arc segments, with an arc transition between adjacent arc segments.

[0010] Preferably, the tangent has multiple adjacent sharp corners, and the sharp corners are isosceles triangles.

[0011] Preferably, the apex angle of the pointed corner is 60°-120°.

[0012] Preferably, the paper body has two surface layers and a line layer located between the two surface layers. The two surface layers are bonded to each other, and the line layer has multiple reinforcing lines extending laterally to both sides of the paper body. The multiple reinforcing lines are bonded between the two surface layers, and the multiple reinforcing lines are parallel to the cut edges.

[0013] Preferably, the surface layer is made of fiber material or leather material.

[0015] It effectively solves the problem of existing honeycomb paper easily loosening after multiple layers of wrapping. The self-adhesive effect is achieved through the mutual restraint of the wavy tangents, eliminating the need for additional restraint steps such as adhesive and temporary restriction, simplifying the packaging operation process and improving packaging efficiency. At the same time, it avoids the product contamination problem that may be caused by the use of adhesive, balancing the tightness of packaging and the cleanliness of the product. It retains the characteristics of the original honeycomb paper, which forms a honeycomb structure by being stretched open by folds, ensuring that the cushioning and protection performance is not affected, and still maintains the environmentally friendly and biodegradable advantages of paper materials. It has significantly improved in terms of convenience, safety and practicality.

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figure 1-5 In this embodiment of the present invention, a convenient self-adhesive honeycomb paper structure includes a paper body with multiple staggered slits 10 covering the paper body, and the slits 10 having a wavy structure. A fold line 20 is provided between adjacent staggered slits 10 on the paper body, and the slits 10 are opened by the fold line 20 to form a honeycomb structure. During packaging, the paper body is first opened by the fold line 20, and the slits 10 unfold with the opening action, causing the paper body to form a honeycomb structure. When the paper body is used to wrap the product in multiple layers, the wavy slits 10 of adjacent layers of paper body will interlock and fit together, utilizing the wavy concave-convex structure to generate a mechanical constraint effect. This achieves a self-constraining effect between adjacent layers without additional adhesive, thus achieving a self-adhesive effect and keeping the package tightly wrapped.

[0028] This design effectively solves the problem of existing honeycomb paper easily loosening after being wrapped in multiple layers. The self-adhesive effect is achieved through the mutual constraint of the wavy tangents 10, eliminating the need for additional constraint steps such as adhesive and temporary restraint, simplifying the packaging operation process and improving packaging efficiency. At the same time, it avoids the product contamination problem that may be caused by the use of adhesive, balancing the tightness of the packaging and the cleanliness of the product. It retains the original honeycomb paper's characteristic of forming a honeycomb structure by being stretched open by the fold lines 20, ensuring that the cushioning and protection performance is not affected, and still maintains the environmentally friendly and biodegradable advantages of paper materials. It has significantly improved in terms of convenience, safety and practicality.

[0029] Please see Figure 2 Based on the above technical solution, a further proposal is made that the area between two adjacent staggered tangents 10 on the paper body is a common segment 30, and there are two fold lines 20 between the two adjacent staggered tangents 10 on the paper body, with the two fold lines 20 located at both ends of the common segment 30; the area between the ends of the two adjacent common segments 30 on the paper body is a transition segment 40. This structure allows adjacent tangents 10 to fit tightly together. After being opened, the four adjacent common segments 30 and two transition segments 40 are connected to form a hexagonal honeycomb structure. Multiple honeycomb structures are arranged sequentially to form a honeycomb structure. When wrapping products, this hexagonal structure combined with the wavy structure can cushion and reduce shock for the product while achieving a self-adhesive restraint effect, greatly improving the ease of use of the paper body.

[0030] Please see Figure 2 Based on the above technical solutions, it is further proposed that the length of the common segment 30 is more than twice the width. When the paper body is spread out along the fold line 20, the longer common segment 30 can guide the tangent 10 to unfold more regularly, so that the hexagonal honeycomb unit extends more fully in the length direction, which improves the density of the wave-like structure, enhances the interlocking depth between adjacent layers, makes the self-adhesive constraint effect more durable, further ensures the tightness of the multi-layer wrapping, makes the connection between adjacent units more coordinated, reduces local wrinkles or twists, and does not affect the buffer space of the honeycomb structure, taking into account both support strength and shock absorption performance, and improving the stability of the overall structure.

[0031] Please see Figure 3-5 Based on the above technical solution, it is further proposed that the tangent opening 10 has multiple arc segments 11, with adjacent arc segments 11 forming an arc transition; for example... Figure 5 As shown, the curved transition allows the wavy tangent edges 10 of adjacent layers to fit more smoothly, reducing jamming while increasing the contact area, making the constraint more stable and less prone to wear on the paper body. Alternatively, the tangent edges 10 may have multiple adjacent sharp corners 12, such as... Figure 4As shown, the pointed corner 12 has an isosceles triangular structure. The symmetrical design of the isosceles triangle ensures uniform force distribution. The apex angle of the pointed corner 12 is 60°-120° to avoid excessively sharp corners that could tear the paper or excessively blunt corners that could affect the constraint. Both of these structures enhance the interlocking ability of the wavy tangent edges 10, making the self-adhesive effect more reliable. At the same time, they adapt to different packaging strength requirements, further improving the tightness and applicability of the packaging.

[0032] Please see Figure 6 Based on the above technical solution, a further proposed method is to have a paper body with two surface layers 50 and a line layer located between the two surface layers 50. The surface layers 50 are made of fiber or leather materials. The use of fiber or leather materials for the surface layers 50 not only retains the flexibility of the packaging material but also enhances its tear resistance and surface abrasion resistance, preventing damage caused by friction or pulling during opening and wrapping. The two surface layers 50 are bonded together, and the line layer has multiple reinforcing lines 60 extending laterally to both sides of the paper body. The multiple reinforcing lines 60 are bonded between the two surface layers 50. Between the layers, multiple reinforcing lines 60 are parallel to the tangents 10; the line layer located between the two surface layers 50 has multiple horizontally extending reinforcing lines 60 that are parallel to and adhere to the tangents 10 between the surface layers 50, forming a supporting skeleton along the direction of force of the honeycomb structure, further strengthening the structural stability of the paper body after it is stretched open, reducing the deformation caused by the constraint of multiple layers of wrapping, and at the same time, the parallel setting of the reinforcing lines 60 and the wavy tangents 10 will not interfere with the interlocking constraint effect of adjacent layers, so that the tightness of the self-adhesive wrapping and the firmness of the overall structure are doubly guaranteed, extending the service life of the packaging.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
