Description
Technical Field
[0001] This utility model relates to the field of woven bag technology, specifically a woven bag with a built-in protective fold. Background Technology
[0002] Woven bags are packaging materials made primarily from chemical fibers such as polypropylene and polyethylene. They are produced through extrusion and stretching into flat filaments, followed by weaving and bag making. Due to their low cost, light weight, high strength, and corrosion resistance, they are widely used in agriculture, industry, logistics, and other fields to carry various items such as grains, fertilizers, and building materials. However, in actual use, due to the external forces such as compression, collision, and friction that may occur during transportation and storage, ordinary woven bags cannot effectively protect the contents, easily leading to damage and economic losses. Therefore, the demand for woven bags with good protective performance is becoming increasingly urgent.
[0003] Traditional woven bags mostly only have basic loading functions and simple structures. Their sides lack special reinforcement designs, making them prone to damage when squeezed during transportation, affecting the overall structural stability. The bag openings are mostly sealed with ropes or simple stitching, resulting in poor sealing. This not only fails to effectively prevent items from falling out but also allows dust and moisture to enter the bag, damaging the contents. Furthermore, the inner walls of the bags usually lack cushioning structures, so when encountering collisions, the contents directly bear the impact force, especially for fragile items and precision instruments, posing a very high risk of breakage. These shortcomings severely limit the application range and effectiveness of traditional woven bags, making it difficult to meet the requirements of modern logistics and goods storage for packaging safety and reliability. Therefore, we have proposed a woven bag with a built-in protective fold. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a woven bag with a built-in protective fold, which solves the above-mentioned problems.
[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a woven bag with a built-in protective fold, comprising a woven bag;
[0006] The woven bag has parallel side folds on both sides;
[0007] The side folded edge has a Z-shaped double folded edge cross section, and an inner folded edge membrane is provided on one side of the inner wall of the side folded edge;
[0008] The inner wall has multiple sets of vertically equidistant honeycomb buffer openings at one end.
[0009] Preferably, the outer wall of the inner folded membrane away from the side fold is fixedly connected with three elastic memory buffer strips that are vertically and equidistantly distributed.
[0010] Preferably, the bottom of the inner wall of the woven bag is provided with a stretchable bottom surface.
[0011] Preferably, a fixing strap is fixedly connected to the outer wall of one end of the woven bag, and Velcro is fixedly connected to the outer wall of the end of the woven bag away from the fixing strap.
[0012] The hook and loop fastener is parallel to the fixing strap, and the end of the fixing strap away from the woven bag is bonded to the outer wall of the hook and loop fastener.
[0013] Preferably, the outer walls of the two ends of the woven bag near the top are respectively movably connected with parallel handles.
[0014] Preferably, a rubber sleeve is fitted onto the outer wall of the top end of the handle.
[0015] Preferably, the outer wall of the rubber sleeve has multiple sets of equidistantly distributed anti-slip grooves.
[0016] Compared with the prior art, this utility model provides a woven bag with a built-in protective fold, which has the following beneficial effects:
[0017] 1. This woven bag with built-in protective folds addresses the common problem of traditional woven bags lacking side reinforcement and being easily damaged. The Z-shaped double-fold design on the side folds, combined with the inner folded membrane on the inner wall, forms a double protective structure. During transportation, when subjected to compression, the Z-shaped structure absorbs impact through deformation, while the inner folded membrane further cushions the pressure, effectively preventing side breakage and ensuring overall structural stability. Simultaneously, the honeycomb buffer openings and elastic memory cushioning strips on the inner wall create a three-dimensional cushioning system. Upon impact, the honeycomb cavity collapses and the elastic memory cushioning strips deform to absorb energy. This contrasts sharply with traditional woven bags, which lack inner wall cushioning, making fragile items highly susceptible to damage. For example, when transporting glassware, traditional woven bags may break with even a slight impact, while this device, with its all-around protective structure, significantly reduces the risk of damage, providing reliable packaging protection for high-value, fragile items.
[0018] 2. This woven bag with built-in protective folds, unlike traditional woven bags which lack a secure folding structure and are prone to loosening and deformation during transport, utilizes a combination of straps and Velcro to dynamically secure the side folds. When the side folds deform due to external pressure, the straps and Velcro firmly bind them together, preventing the Z-shaped structure from failing due to excessive deformation. This design acts like a "dynamic support skeleton" for the folds. In scenarios where the protective performance of traditional woven bags deteriorates due to loose folds (such as side collapse after repeated loading and unloading), this device maintains the integrity of the fold structure, ensuring long-term side protection. For example, when handling building materials, the sides of traditional woven bags may collapse due to repeated friction and pressure, losing their cushioning capacity. This device, through the combined fixation of straps and Velcro, maintains the Z-shaped structure of the side folds, continuously protecting the contents.
[0019] 3. This woven bag with a built-in protective fold is different from traditional woven bags, whose handles are usually made of ordinary woven straps that can easily hurt your hands when lifting heavy objects and are slippery. The handle of this device has a rubber sleeve at the top, made of soft material, which can effectively relieve pressure on the hand and greatly improve the comfort of lifting. At the same time, the anti-slip grooves on the outer wall of the rubber sleeve increase the surface friction, ensuring a firm grip even if your hands are sweaty or the contents of the bag are heavy, and preventing slippage. For example, when moving heavy building materials or food, using a traditional woven bag may increase the burden of carrying due to an uncomfortable handle, and there is even a risk of it falling. This device, with its user-friendly handle design, makes the carrying process easier and safer, fully considering the user experience and reflecting the practicality and humanistic care of the design.

[0025] 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.
[0026] Please see Figure 1-4 A woven bag with a built-in protective fold, comprising a woven bag 1, which serves as the main body for carrying various items and is the basic carrier for realizing the function of the entire woven bag;
[0027] The woven bag 1 has parallel side folds 2 on both sides. The side folds 2 protect and reinforce the sides of the woven bag 1, and enhance the side's resistance to compression and wear.
[0028] The side fold 2 has a Z-shaped double fold in cross section. The inner wall of the side fold 2 is provided with a fold inner membrane 3. The Z-shaped double fold design can absorb the impact force through its own structural deformation when subjected to external force. The fold inner membrane 3 further enhances the cushioning performance of the side, providing double protection for the side and reducing the impact of external pressure on the items inside the bag.
[0029] Multiple sets of vertically equidistant honeycomb buffer openings 4 are provided at one end of the inner wall. The honeycomb buffer openings 4 utilize the mechanical properties of the honeycomb structure to absorb energy through cavity collapse when impacted, thereby providing buffer protection for the inner wall of the woven bag 1 and reducing the risk of damage to the internal items.
[0030] Three vertically equidistant elastic memory buffer strips 5 are fixedly connected to the outer wall of the inner folded membrane 3 on the side away from the side folded edge 2. The elastic memory buffer strips 5, relying on their own elastic memory function, quickly rebound after being squeezed, and cooperate with the honeycomb buffer opening 4 to form a buffer system from point to surface, which enhances the protection of the items in the bag in all aspects.
[0031] The bottom of the inner wall of the woven bag 1 is provided with a stretchable bottom surface 6. When loaded with heavy objects, the stretchable bottom surface 6 can be stretched and deformed appropriately according to the shape of the objects, so that the bottom is evenly stressed, which improves the load-bearing capacity and damage resistance of the bottom of the woven bag 1 and extends its service life.
[0032] A fixing strap 7 is fixedly connected to the outer wall of one end of the woven bag 1, and a Velcro 8 is fixedly connected to the outer wall of the end of the woven bag 1 away from the fixing strap 7.
[0033] The Velcro 8 is parallel to the fixing strap 7. The end of the fixing strap 7 away from the woven bag 1 is bonded to the outer wall of the end of the Velcro 8. This bonding method ensures that the bag opening can be tightly sealed, while facilitating quick opening and closing and improving ease of use.
[0034] The outer walls of the two ends of the woven bag 1 near the top are respectively connected to parallel handles 9, which provide users with a convenient way to lift and move the items inside the woven bag 1.
[0035] A rubber sleeve 10 is fitted onto the outer wall of the top end of the handle 9. The rubber sleeve 10 is made of soft material, which can reduce the pain of the handle 9 on the hand and improve the comfort when carrying it.
[0036] The outer wall of the rubber sleeve 10 has multiple sets of equidistant anti-slip grooves 11. The anti-slip grooves 11 increase the friction of the surface of the rubber sleeve 10, prevent the handle 9 from slipping out of the hand, and ensure a safe and stable lifting process.
[0037] Working principle: First, a Z-shaped double-folded edge design (Z-shaped cross-section) is adopted. This structure itself can absorb part of the impact force through the deformation of the folded edge when subjected to external pressure. The inner folded edge membrane 3 set on one side of the inner wall of the side folded edge 2 can further enhance the side's resistance to compression. When external pressure is applied to the side folded edge 2, the inner folded edge membrane 3 can buffer the pressure with its own material toughness, reducing the transmission of pressure to the items inside the woven bag 1. Through the coordinated linkage of the honeycomb buffer opening 4 and the elastic memory buffer strip 5, a three-dimensional buffering effect on the inner wall of the woven bag 1 is achieved. Multiple sets of vertically equidistant honeycomb buffer openings 4 (in a honeycomb structure) are opened on the inner wall. When impacted, the honeycomb cavities will collapse, thereby absorbing the impact energy and playing a preliminary buffering role. At the same time, three vertically equidistant elastic memory buffer strips 5 are fixedly connected to the outer wall on the side away from the side fold 2 of the inner folded membrane 3. They have elastic memory function and can quickly return to their original shape after being squeezed. After the initial buffering by the buffer openings 4, the elastic memory buffer strips 5 can further absorb the aftershocks through their own elastic deformation. The two work together to form a buffer system from point to surface, protecting the items inside the bag in all directions. Through the structural design linkage of the stretched bottom surface 6, the bottom of the woven bag 1 is reinforced and its load-bearing capacity is improved. The stretchable bottom surface 6 provided on the inner wall of the woven bag 1 is made of a material with a certain degree of extensibility. When loaded with heavy objects, the stretchable bottom surface 6 can stretch and deform appropriately according to the shape of the heavy objects, so that the bottom is more evenly stressed and avoids the bottom from cracking due to excessive local stress. At the same time, the stretchable bottom surface 6 and the woven structure at the bottom of the woven bag 1 work together to enhance the overall load-bearing capacity of the bottom and effectively extend the service life of the woven bag 1. Through the connection and linkage of the fixing strap 7 and the Velcro 8, the opening of the woven bag 1 can be opened and closed conveniently and sealed and reinforced. The fastening strap 7 on one end of the outer wall of the woven bag 1 is parallel to the Velcro 8 on the other end. The end of the fastening strap 7 away from the woven bag 1 is adhesively fitted to the outer wall of the Velcro 8. When sealing is required, the fastening strap 7 is attached to the Velcro 8. Through the adhesive action of the hook and loop sides of the Velcro 8, the bag opening can be tightly fixed to prevent items from falling out. When the bag opening needs to be opened, simply tear off the adhesive joint between the fastening strap 7 and the Velcro 8. The operation is simple and convenient. This connection method not only ensures the sealing of the bag opening, but also facilitates the opening and closing operation in daily use. Through the structural linkage of the handle 9, the rubber sleeve 10, and the anti-slip groove 11, a comfortable grip and anti-slip effect are achieved when carrying the woven bag 1. The handles 9, which are movably connected to the outer walls near the top two ends of the woven bag 1, provide users with a point of lifting. The rubber sleeve 10, which is fitted onto the outer wall of the top end of the handle 9, is made of soft rubber material, which can reduce the pain on the hand when lifting heavy objects and improve the grip comfort. The multiple sets of equidistant anti-slip grooves 11 on the outer wall of the rubber sleeve 10 increase the friction of the surface of the rubber sleeve 10, and can effectively prevent the handle 9 from slipping out of the hand even if the hands are sweaty or the contents of the bag are heavy, ensuring the stability and safety of the lifting process.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
