Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, specifically a double-sided perforated rope handle bag. Background Technology

[0002] A tote bag is a common portable container, usually made of flexible materials (such as cloth, plastic, paper or non-woven fabric), with a bag-like structure to hold items, and a handle (such as a rope, cloth strap or rigid handle) near the opening for easy carrying by hand or over the shoulder.

[0003] Currently, common drawstring tote bags have many shortcomings in their structural design. Most tote bags require the drawstring to be fixed to the front of the bag opening when connecting to the bag body, which not only ruins the aesthetics of the front of the bag but also easily leads to unevenness at the opening. The manufacturing process is relatively cumbersome, with complex steps for connecting the drawstring to the bag body, increasing production difficulty. Furthermore, the drawstring is usually fixed to the bag body, making it difficult to disassemble and reuse for bundling items.

[0004] Therefore, a double-sided perforated rope handle bag is proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a double-sided perforated rope tote bag to solve the structural design problems of commonly used rope tote bags mentioned in the background art, such as the rope connection to the bag body damaging the aesthetics of the front of the bag, resulting in an uneven bag opening, complex manufacturing process, and the rope being difficult to disassemble and reuse.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a double-sided perforated rope handle bag, comprising a bag body and a handle bearing part, wherein a bag opening connection part is fixedly connected to the top of the bag body, and one or two first through holes are opened on each of the left and right sides of the bag body, and the handle bearing part passes through the first through hole and is provided with limiting parts at both ends;

[0007] The bag body is fixedly connected to a first bearing plate inside the first through hole, and the bag opening connection part is fixedly connected to a second bearing plate inside the second through hole at the position corresponding to the first through hole. When the bag opening connection part is bent along the pre-indentation line, the second bearing plate and the first bearing plate form a close fit connection.

[0008] The bag body has a third bearing plate fixedly connected to the inner side of the top of both the front and rear sides. A fourth bearing plate is attached to one side of the third bearing plate, and the other side of the fourth bearing plate is fixedly connected to the inner wall of the bag opening connection part.

[0009] Preferably, when there is one first through hole, it is located at the center of the top of the left and right sides of the bag body; when there are two first through holes, they are symmetrically distributed on both sides of the center of the top of the left and right sides of the bag body.

[0010] Preferably, the handle bearing part is a carrying rope or a carrying strap.

[0011] Preferably, the limiting part is a fixed metal block or a limiting structure formed by knotting.

[0012] Preferably, the first, second, third, and fourth support plates are made of rigid plastic or corrugated cardboard to enhance the local structural strength of the handle connection area.

[0013] Preferably, the bag opening connector is integrally formed with the bag body.

[0014] Preferably, the first and second bearing plates are bonded together by adhesive, and the third and fourth bearing plates are bonded together by adhesive.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This double-sided perforated rope-strap tote bag, by connecting the handle support to the through holes on the side of the bag body, achieves a complete and beautiful front of the bag body, simplifies the production process, allows the rope to be detached and reused, and enhances the stability and load-bearing capacity of the connection parts through the multi-layer bearing plate structure, comprehensively improving the tote bag's aesthetics, practicality, and environmental friendliness. The specific details are as follows:

[0016] First, it effectively improves the aesthetics and smoothness of the bag's front. In existing technologies, the connection between the straps and the bag body is mostly fixed at the front of the bag opening, inevitably compromising the integrity of the front and affecting its appearance. It also easily leads to unevenness such as bulges and wrinkles at the bag opening. This invention, however, places the first through-hole on the left and right sides of the bag body, with the handle support connected to the bag body through the side through-holes. This eliminates the need for any connecting structure on the front of the bag, keeping the front intact and smooth, greatly improving the overall aesthetics of the tote bag. This design also facilitates personalized processing on the front of the bag, such as printing patterns, engraving, or other decorative treatments, further enhancing the tote bag's practicality and promotional effect.

[0017] Secondly, it simplifies the production process and reduces production difficulty. Existing methods for connecting the straps to the bag body are complex, often requiring multiple steps for fixation, increasing production complexity and cost. This invention addresses this by creating a first through-hole on the side of the bag body, through which the handle support directly passes and is fixed by limiting parts at both ends. This simple and direct connection method reduces the steps involved in connecting the straps to the bag body, simplifying the manufacturing process, improving production efficiency, reducing production difficulty and cost, and making it more suitable for large-scale industrial production.

[0018] Secondly, the design achieves detachability of the handle support, facilitating reuse. In existing technologies, the straps are typically fixed to the bag body, making them difficult to detach and preventing reuse. In this invention, the handle support is inserted into a first through-hole on the side, connected to the bag body by a limiting part. When the bag is finished or the handle support needs replacement, it can be easily removed from the through-hole. This allows the handle support to be reused, for example, for bundling items, improving resource utilization and aligning with energy conservation and environmental protection principles.

[0019] Furthermore, the structural stability and load-bearing capacity are enhanced. In this invention, a first bearing plate is fixedly connected to the inside of the first through hole of the bag body, and a second bearing plate is fixedly connected to the inside of the second through hole at the corresponding position of the bag opening connection. When the bag opening connection is bent along the pre-indentation line, the second bearing plate and the first bearing plate are closely connected, which can effectively enhance the local structural strength of the connection between the handle bearing part and the bag body. At the same time, the third bearing plate on the inner side of the top of the front and rear sides of the bag body is closely connected to the fourth bearing plate on the inner wall of the bag opening connection, further improving the stability of the bag opening and the overall structure. The above designs work together to make the force distribution more even when the bag is under load, reduce the risk of damage to the connection part due to excessive force, and extend the service life of the bag.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1 (Single-hole handle tote bag)

[0030] like Figure 1 As shown, this embodiment provides a single-hole handle type double-sided perforated rope bag, the structure of which includes a bag body 1 and a handle support part 4. The bag body 1 is made of kraft paper and has an overall rectangular structure. The top edge is integrally formed with a bag opening connection part 2. The width of the bag opening connection part 2 is the same as the width of the top of the bag body 1, and it can be bent inward along the preset pre-indentation line 11.

[0031] Each of the left and right sides of the bag body 1 has a first through hole 3 at the center of its top. The diameter of the through hole is 2cm, and the edges are rounded to avoid wear on the handle support part 4. The handle support part 4 is made of canvas handle with a width of 3cm. Its two ends pass through the first through hole 3 and the second through hole 7 on the left and right sides, respectively. A limiting part 5 is formed by sewn-on metal blocks. The limiting part 5 is 4cm wide to ensure that the handle will not fall out of the through hole.

[0032] Inside the bag body 1, a first support plate 6 is fixedly connected to the first through hole 3 via hot melt adhesive. This support plate is made of 1mm thick rigid PVC plastic and completely covers a 2cm radius around the first through hole 3 to enhance the tear resistance at the through hole. The bag opening connection part 2 has a second through hole 7 at the position corresponding to the first through hole 3. The second through hole 7 has the same diameter as the first through hole (3), and a second support plate 8 is also fixed to its inner side via hot melt adhesive. Its material is the same as the first support plate 6. When the bag opening connection part 2 bends inward along the pre-indentation line 11, the second support plate 8 and the first support plate 6 are tightly bonded together via double-sided adhesive, further improving the structural strength of the connection part.

[0033] In addition, a third support plate 9 is fixedly connected to the inner sides of the top of both the front and back sides of the bag body 1 with white glue. The third support plate 9 is made of corrugated cardboard, with a thickness of 1mm, a length consistent with the width of the bag body 1, and a width of 3cm. A fourth support plate 10 is attached to the inner side of the third support plate 9. The fourth support plate 10 is also made of corrugated cardboard, with the same dimensions as the third support plate 9, and is fixed to the inner wall of the bag opening connection part 2 with white glue, forming a double-layer reinforcement structure, effectively distributing the force on the bag opening when carried by hand.

[0034] Example 2 (Single-hole carrying rope metal block tote bag)

[0035] like Figure 2 As shown, the main difference between this embodiment and Embodiment 1 lies in the structure of the handle support part 4. The handle support part 4 uses a nylon carrying rope with a diameter of 0.8cm, and the surface of the rope is treated with anti-abrasion coating. The first through hole 3 at the center of the top on both sides of the bag body 1 has a diameter of 1cm, which is adapted to the size of the carrying rope.

[0036] After the two ends of the carrying rope pass through the first through hole 3, they are fixedly connected to the limiting part 5. The limiting part 5 is a metal block, which is fixed to the end of the carrying rope by welding to form a solid limiting structure to prevent the carrying rope from slipping out of the through hole.

[0037] In this embodiment, the first support plate 6 and the second support plate 8 are made of rigid plastic with a thickness of 0.8mm, and the third support plate 9 and the fourth support plate 10 are made of corrugated cardboard. The connection method and positional relationship of each component are the same as in embodiment 1.

[0038] Example 3 (Single-hole handle with knotted rope tote bag)

[0039] like Figure 3 As shown, this embodiment is a single-hole handle rope knotted structure. The bag body 1, bag opening connection 2, and first through hole 3 are the same as in embodiment 2, the difference being the form of the limiting part 5. The handle bearing part 4 is a 0.6cm diameter polyester handle rope. After both ends pass through the first through hole 3, the limiting part 5 is formed by manually knotting. The knot diameter is 1.2cm, and it is heat-fused to fix the knot and prevent it from loosening.

[0040] The first support plate 6 and the second support plate 8 are made of 1mm thick corrugated cardboard and are fixed to the inside of the first through hole 3 and the second through hole 7 respectively with white glue; the third support plate 9 and the fourth support plate 10 are made of rigid PVC plastic and are bonded together with hot melt adhesive. The rest of the structure is consistent with the above embodiment. Embodiment 4 (Double-hole handle knotted tote bag)

[0041] like Figure 4As shown, this embodiment features a double-hole, knotted handle structure. Two first through holes 3 are opened on the top of each of the left and right sides of the bag body 1. These two through holes are symmetrically distributed on both sides of the center of the side, with a spacing of 3cm. Each through hole has a diameter of 0.7cm. The handle support 4 consists of two independent nylon handles. The two ends of each handle pass through the two first through holes 3 on the same side and are knotted to form a limiting part 5. The knot diameter is 1.3cm, and the knots are fixed by heat fusion.

[0042] The bag opening connection part 2 has a second through hole 7 corresponding to each first through hole 3, and a second support plate 8 is fixed inside. Both the first support plate 6 and the second support plate 8 are made of corrugated cardboard and are fixed with white glue. The third support plate 9 and the fourth support plate 10 are made of rigid plastic and are connected by double-sided adhesive. The rest of the structure is the same as in embodiment 3.

[0043] Example 5 (Double-hole handle with metal block tote bag)

[0044] like Figure 5 As shown, this embodiment features a double-hole carrying rope metal block structure. Two first through holes 3 are opened on each of the left and right sides of the bag body 1. The distribution and size of the through holes are the same as in embodiment 4. The carrying support part 4 is a polyester carrying rope, which passes through the through holes at both ends and is connected to the limiting part 5. The limiting part 5 is a stainless steel metal block, which is fixed to the carrying rope by riveting. The metal block has a diameter of 1.4 cm and a thickness of 0.4 cm.

[0045] The first support plate 6 and the second support plate 8 are made of rigid PVC plastic, while the third support plate 9 and the fourth support plate 10 are made of corrugated cardboard. The connection method of each component is the same as that in Example 4. Multiple reinforcements are used to ensure that the force is balanced at the double hole positions.

[0046] Example 6 (Double-hole handle tote bag)

[0047] like Figure 6 As shown, this embodiment features a double-hole handle structure. Two first through holes 3 are opened on the top of each of the left and right sides of the bag body 1, spaced 4cm apart and 2cm in diameter. The handle support 4 is a canvas handle. After passing through the two through holes on each side, the two ends are sewn together to form a limiting part 5 with a sewing width of 5cm, ensuring a secure connection with the through holes.

[0048] The first support plate 6 and the second support plate 8 are made of 1.2mm thick rigid plastic, completely covering the through hole and the surrounding 3cm range; the third support plate 9 and the fourth support plate 10 are double-layer corrugated cardboard, which are tightly bonded together with white latex to further enhance the load-bearing capacity of the bag opening. In this embodiment, the integral molding structure of the bag opening connection part (2) and the bag body 1 ensures the overall structural stability, and the rest of the settings are consistent with the above-mentioned double-hole embodiment.

[0049] Working principle: Before using this type of double-sided perforated rope handle bag, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 7 As shown, during the structural assembly stage, after the bag opening connection 2 at the top of the bag body 1 is bent along the pre-indentation line 11, the second support plate 8 and the first support plate 6 form a close connection. Through the superposition and reinforcement of the two rigid plates (the first support plate 6 and the second support plate 8 are made of rigid plastic or corrugated cardboard), a high-strength stress area is formed around the first through hole 3. At the same time, the third support plate 9 on the inner side of the top of the front and rear sides of the bag body 1 is closely connected to the fourth support plate 10 on the inner wall of the bag opening connection 2, further improving the overall structural strength of the bag opening connection 2 and the bag body 1, and preventing the bag opening from deforming due to stress.

[0050] The handle support part 4 (handle rope or handle strap) is inserted into the first through hole 3 and the second through hole 7 on the left and right sides of the bag body 1. The limiting parts 5 at both ends (fixing metal blocks or knotted structures) can prevent the handle support part 4 from falling out of the through holes. When the handle support part 4 is subjected to external force, the tension is transmitted through the first through hole 3 to the contact area between the first support plate 6 and the second support plate 8. Since this area is reinforced by double plates and the stress is dispersed by the synergistic effect of the third support plate 9 and the fourth support plate 10, the problem of local stress concentration caused by the traditional method of fixing the front of the bag opening can be effectively avoided.

[0051] During use, because the handle support part 4 adopts a double-sided opening design, it does not need to be fixed on the front of the bag body 1, which maintains the integrity and aesthetics of the front of the bag body 1 and avoids unevenness at the bag opening. The handle support part 4 is connected to the bag body 1 by a through-hole method, which simplifies the production process and reduces the manufacturing difficulty. When it is necessary to disassemble the handle support part 4, it can be pulled out from the first through hole 3 and the second through hole 7 simply by releasing the constraint of the limiting part 5, so as to achieve secondary use (such as bundling items), which solves the problem that traditional ropes cannot be disassembled.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
