Description

Technical Field

[0001] This invention belongs to the field of cardboard box and paper bag production, and in particular relates to an environmentally friendly paper strap handle. Background Technology

[0002] Traditional cardboard box or bag handles are mostly made of plastic, but plastic handles have drawbacks such as high cost, environmental unfriendliness, and difficulty in recycling. They need to be separated from the cardboard box before recycling, resulting in high recycling costs. Therefore, they have gradually been replaced by paper handles. While paper strip handles are more environmentally friendly, they suffer from low strength and are prone to tearing and breakage. Increasing the thickness of the paper strip and using thicker cardboard to make the handle can improve strength to some extent, but it still cannot completely solve the problem of easy breakage. Cardboard handles will still break under lateral twisting or uneven stress, and the increased material usage also raises production costs. Although existing technologies use paper rope as handles, paper bags or boxes with paper rope handles are uncomfortable to hold when carrying heavy objects. Therefore, the inventors developed the paper strip handle of this invention, effectively overcoming the above-mentioned defects. Summary of the Invention

[0003] The problem to be solved by this invention is to overcome the defects existing in the prior art and to propose an environmentally friendly paper tape handle.

[0004] To solve the above-mentioned technical problems, the technical solution created by this invention is implemented as follows:

[0005] An environmentally friendly paper strip handle includes a flat handle body made of paper strip, with at least two paper ropes wrapped inside the handle body. One paper rope is arranged on each side of the handle body near the edge in the width direction, and the paper ropes are fixed to the handle body.

[0006] Furthermore, the handle body is made of rolled paper strip, with the two sides of the paper strip overlapping in the width direction.

[0007] Furthermore, the overlapping portions of the paper strip on both sides of the handle body are glued and fixed.

[0008] Furthermore, the handle body is made of rolled paper strip, and both sides of the paper strip in the width direction form a butt joint structure. The butt joint structure is located in the middle of the upper side of the handle body, and a paper rope is arranged on each side of the butt joint structure.

[0009] Furthermore, the docking structure includes a docking portion that retracts inward toward the inner side of the handle body, and a joint portion that fits with the paper rope at the end of the docking portion. The docking portion and the joint portion are uniformly glued and fixed with paper rope, and the docking portions on both sides in the width direction of the paper strip are glued and fixed.

[0010] Furthermore, a transition section is provided between the docking structure and the paper tape body. The transition section has an arc-shaped structure and forms a deformation seam between the transition sections of the docking structures on both sides. The length of the deformation seam is the same as the length of the handle body, which can protect the handle body.

[0011] Furthermore, the handle body has a width of 10-20mm.

[0012] Furthermore, the diameter of the paper rope is 1-3 mm.

[0013] Furthermore, the edges on both sides of the handle body have an arc-shaped structure.

[0014] The advantages and positive effects of this invention are:

[0015] This invention features a simple and rationally designed structure. The handle body is formed by winding paper strips and wrapping paper rope inside the handle body. This ensures high tensile strength while preventing side breakage, resulting in good durability and comfort. The handle provided by this invention can replace existing plastic handles, is easy to recycle, environmentally friendly, has low production costs, high production efficiency, and good economic benefits.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] The specific embodiments of the present invention will be described in detail below.

[0029] An environmentally friendly paper strap handle, such as Figures 1 to 7As shown, the invention includes a flat, cylindrical handle body 1 made of paper strip. At least two paper ropes are wrapped inside the handle body. One side reinforcing paper rope 2 is arranged near the edge on each side of the handle body in the width direction, and the paper ropes are fixed to the handle body. Typically, the paper ropes are glued to the handle body. For example, during production, the inner surface of the paper strip is coated with a hot melt adhesive film. While the paper strip is being formed into the handle body, the paper ropes are wrapped within it. After heat treatment, the handle body and paper ropes are glued together. After cooling, the finished paper strip is obtained. It should be noted that the length of the paper strip handle provided by this invention is usually customized by the customer. During routine production, it can be continuously formed into uncut paper strip handles, which increases production efficiency and facilitates sales, transportation, and storage. The customer then cuts the handle for use. For example, the handle body width is 10-20mm, and the paper rope diameter is 1-3mm. Of course, it can also be produced according to the actual needs of the customer.

[0030] Usually, such as Figures 1 to 3 As shown, the handle body is made of rolled paper strip, with the two sides 3 overlapping in the width direction of the paper strip. Under normal circumstances, the overlapping parts of the paper strip on both sides of the handle body are glued and fixed, that is, the inner surface of the paper strip is coated with hot melt adhesive film. When the paper strip is formed into the handle body, heating melts the hot melt adhesive film, so that the overlapping parts of the paper strip on both sides are glued and fixed.

[0031] In an optional embodiment, such as Figures 4 to 6 As shown, the handle body is made of rolled paper strip, with a butt joint structure 4 formed on both sides of the paper strip in the width direction. This butt joint structure is located in the middle of the upper side of the handle body, and a central reinforcing paper rope 9 is arranged on both sides of the butt joint structure. Specifically, the butt joint structure includes a butt joint portion 5 that tapers inward toward the inside of the handle body, and a joint portion 6 that fits with the paper rope at the end of the butt joint portion. The butt joint portion and the joint portion are uniformly glued and fixed with paper rope, and the butt joint portions on both sides of the paper strip in the width direction are also glued and fixed.

[0032] The connecting structure extends into the handle body, effectively enhancing the tensile strength of the handle body. As the foundation for the central reinforcing paper rope, it ensures that the central reinforcing paper rope is firmly fixed and has good structural stability. This, in turn, ensures that the handle has better overall durability and more outstanding tensile and anti-breakage capabilities.

[0033] Specifically, such as Figure 7As shown, a transition portion 7 is provided between the aforementioned docking structure and the paper tape body. The transition portion has an arc-shaped structure, forming a deformation seam 8 between the transition portions of the two side docking structures. The length direction of this deformation seam is consistent with the length of the handle body. This effectively ensures that when the handle is subjected to torsional force, the deformation seam will undergo contraction or expansion deformation within the deformation range. This not only effectively protects the handle from damage to the handle body but also effectively buffers the load. When lifting heavy objects, the deformation seam adapts to the continuous changes in load (with bumps) during the lifting and walking process, resulting in continuous contraction and expansion. This maximizes the protection of the handle from damage and effectively buffers the impact of the weight of the heavy object on the hand, resulting in excellent comfort. The supporting effect of the docking portions on both sides, coupled with the fixing of the docking portions and the connecting portions with the paper tape, also forms a supporting effect, thus effectively improving the strength at the location of the deformation seam of the handle, playing a supporting and protective role, and allowing the aforementioned buffering and adaptive deformation performance to be fully utilized.

[0034] The side reinforcing paper ropes at the edge of the handle body and the center reinforcing paper ropes on the inner side of the joint structure effectively improve the strength of the handle, making it more resistant to tensile stress. The paper ropes at the edge can effectively prevent the handle body from breaking sideways. As a further improvement, the edges on both sides of the handle body are arc-shaped structures 12. The arc-shaped structures fit snugly with the side reinforcing ropes, providing good resistance to torsional deformation and further preventing side breakage.

[0035] In an optional embodiment, to further enhance the tensile strength of the handle, the paper cords inside the handle body are tightly arranged, i.e., as shown... Figure 8 As shown, inside the handle body, in the space between the central reinforcing paper rope and the side reinforcing paper ropes, auxiliary reinforcing paper ropes 11 are arranged side by side, so that each pair of adjacent paper ropes are closely fitted together. This makes the handle body a core composed of paper ropes, which helps maintain the position of each paper rope and effectively distributes the pressure on the paper ropes, preventing discomfort during use and ensuring comfort. As a further improvement, the portion of the handle body located between the two paper ropes is squeezed to fit snugly against the paper ropes, i.e., as shown... Figure 9 As shown, the handle body has a bonding portion 10 located between the two paper ropes, ensuring a secure connection between the handle body and the paper ropes. This prevents the internal paper ropes from loosening due to twisting, resulting in excellent stability. This structural design distributes torsional deformation of the handle to the recessed areas on the outer sides of each bonding portion, improving overall bending and torsional resistance, durability, and user comfort. Furthermore, the handle's load-bearing capacity, pressure resistance, and bending resistance are significantly enhanced, making it suitable for applications with higher requirements. As an extension of its applications, this invention can also be used in packaging box straps, paper bag reinforcement straps, and other applications, demonstrating a wide range of applicability.

[0036] This invention features a simple and rationally designed structure. The handle body is formed by winding paper strips and wrapping paper rope within the handle body, ensuring high tensile strength while preventing side breakage, resulting in good durability and comfort. Especially in designs with a connecting structure, the overall tensile performance and structural stability are even better. The handle provided by this invention can replace existing plastic handles, is easy to recycle, environmentally friendly, has low production costs, high production efficiency, and good economic benefits.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
