Description

Technical Field

[0001] This utility model relates to the field of kraft paper bag technology, and more specifically to a non-slip and durable kraft paper bag. Background Technology

[0002] Kraft paper bags are non-toxic, odorless, and pollution-free, and are characterized by high strength and environmental friendliness. They are one of the most popular environmentally friendly packaging materials internationally. Kraft paper bags are widely used in supermarkets, shopping malls, shoe stores, clothing stores, restaurants, and other places to package goods and make them convenient for customers to carry.

[0003] Existing commercial takeaway paper bags have significant shortcomings in their opening design. Most bags are completely open, and when items are placed inside, such as when a delivery person hangs the bag with items on their vehicle, the items can easily fall out of the open bag if the vehicle encounters bumps. Patent CN219116135U proposes adding a magnetic closure structure to the bag opening, which can achieve a closed opening, but still has functional defects: when the items inside the bag are shaken during transport, the lateral impact force can easily break through the magnetic attraction force of the bag opening, causing the bag opening to open again. In addition, the magnetic attraction force has a fixed threshold. When the weight of the items inside the bag exceeds the load-bearing capacity, or when the bag encounters a large external impact such as sudden braking or acceleration during transport, the inertial force generated by the items inside the bag may exceed the magnetic attraction limit, ultimately causing the items to fall out. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a non-slip and durable kraft paper bag to solve the problems existing in the background art.

[0005] The utility model provides the following technical solution: a non-slip and durable kraft paper bag, comprising a kraft paper bag body, wherein anti-slip strips are equidistantly and transversely fixedly connected to the inner wall of the kraft paper bag body, and mounting holes are provided on both sides of the kraft paper bag body. A sliding component is installed in two mounting holes on one side of the kraft paper bag body, and a limiting component is installed in two mounting holes on the other side of the kraft paper bag body. A pull rope is fixedly connected to the surface of the mounting hole, and a pull rope is fixedly connected to the surface of the limiting component.

[0006] Furthermore, the sliding assembly includes a fixing plate that is fixedly bonded inside the mounting hole. A magnet is fixedly connected inside the fixing plate. A groove is formed on the surface of the fixing plate. Limiting grooves are formed on both sides of the groove. A sliding plate is slidably connected inside the groove. The end face of the pull rope is fixedly connected to the surface of the sliding plate. A locking plate is fixedly connected to the surface of the sliding plate near the limiting assembly.

[0007] Furthermore, the limiting component includes a fixing plate two fixedly bonded inside the mounting hole, the end face of the pull rope two fixedly connected to the surface of the fixing plate two, an iron plate fixedly connected inside the fixing plate two, a slot opened on the surface of the fixing plate two, a positioning groove opened inside the fixing plate two, and the inside of the positioning groove communicating with the inside of the slot.

[0008] Furthermore, the card plate is L-shaped, and limit plates are fixedly connected to both sides of the slide plate. The outer surface of the limit plate is slidably connected to the inside of the limit groove.

[0009] Furthermore, the card plate matches the positioning groove, and the anti-slip strip is a silicone rubber strip.

[0010] Furthermore, after the kraft paper bag body is closed, the surface of the magnet is magnetically fixed to the surface of the iron plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model, by fixing silicone rubber anti-slip strips at equal intervals laterally on the inner wall of the kraft paper bag, can effectively increase the friction between the bag and the items inside, preventing the items from sliding up and down inside the bag. Especially when carrying or hugging the paper bag, it can significantly improve the stability of the items and reduce the risk of bag damage or items falling due to sliding.

[0013] 2. This utility model features a dual closure structure for the bag opening, employing both magnetic adsorption and card plate positioning. After the main body of the kraft paper bag is closed, the magnet and the iron plate are magnetically attracted and fixed, initially achieving bag closure. When the handle pulls the first rope, the sliding plate drives the "L"-shaped card plate to slide along the slot and embed into the positioning groove, forming a mechanical lock. This can withstand greater lateral impact and inertial force, avoiding the problem of the bag opening opening caused by insufficient adsorption force of a traditional single magnet, thus improving the safety of the goods during transportation. The limiting plates on both sides of the sliding component cooperate with the limiting groove to ensure smooth sliding of the sliding plate and prevent card plate offset. The slot and positioning groove of the limiting component are connected, so that the card plate forms a stable "L"-shaped locking position after embedding, further enhancing the reliability of the closure structure. At the same time, the setting of the first and second pull ropes facilitates carrying and opening / closing operations, taking into account both practicality and convenience.

[0019] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0020] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0021] A non-slip and durable kraft paper bag includes a kraft paper bag body 1. Anti-slip strips 2 are equidistantly and horizontally fixedly connected to the inner wall of the kraft paper bag body 1. Mounting holes 3 are opened on both sides of the kraft paper bag body 1. Sliding components 4 are installed in two mounting holes 3 on one side of the kraft paper bag body 1, and limiting components 6 are installed in two mounting holes 3 on the other side of the kraft paper bag body 1. Pull cord 1 5 is fixedly connected to the surface of the mounting hole 3, and pull cord 2 7 is fixedly connected to the surface of the limiting component 6.

[0022] In this implementation scheme, the anti-slip strips 2 are equidistantly and laterally fixed to the inner wall of the kraft paper bag body 1, which can increase the friction with the items inside the bag and prevent the items from sliding up and down inside the bag. Especially when carrying or hugging the paper bag, it can significantly improve the stability of the items and reduce the risk of damage to the kraft paper bag body 1 or items falling off due to sliding.

[0023] Specifically, the sliding component 4 includes a fixing plate 41 fixedly bonded inside the mounting hole 3. A magnet 42 is fixedly connected inside the fixing plate 41. A groove 43 is formed on the surface of the fixing plate 41. Limiting grooves 44 are formed on both sides of the groove 43. A sliding plate 45 is slidably connected inside the groove 43. The end face of the pull rope 5 is fixedly connected to the surface of the sliding plate 45. A locking plate 46 is fixedly connected to the surface of the sliding plate 45 near the limiting component 6.

[0024] In this embodiment, the magnet 42 inside the fixing plate 41 is magnetically fixed to the iron plate 64 of the limiting component 6, which can initially close the bag opening and prevent items from being thrown out of the open bag opening. The slide plate 45 and the locking plate 46 are mechanically locked. When the hand pulls the rope 5, the pulling force drives the slide plate 45 to slide along the slide groove 43, so that the "L"-shaped locking plate 46 is embedded into the positioning groove 63 of the limiting component 6, forming a mechanical locking structure that can withstand greater lateral impact and inertial force, avoiding the problem of the bag opening being open due to insufficient attraction force of a single magnet. The limiting plates 451 on both sides of the slide plate 45 cooperate with the limiting groove 44 to ensure that the slide plate 45 slides smoothly, prevent the locking plate 46 from shifting, and improve the reliability of the closing structure.

[0025] Specifically, the limiting component 6 includes a fixing plate 61 fixedly bonded inside the mounting hole 3, the end face of the pull rope 7 fixedly connected to the surface of the fixing plate 61, an iron plate 64 fixedly connected inside the fixing plate 61, a slot 62 opened on the surface of the fixing plate 61, a positioning groove 63 opened inside the fixing plate 61, and the interior of the positioning groove 63 is connected to the interior of the slot 62.

[0026] In this embodiment, the iron plate 64 inside the fixing plate 61 is magnetically fixed to the magnet 42, providing an initial closing force. Combined with the mechanical locking of the card plate 46, a double closing structure is formed. The slot 62 and the positioning groove 63 are connected, so that the card plate 46 is embedded to form a stable "L" shaped card position, which further enhances the impact resistance of the closing structure and prevents the bag opening from opening due to external impact.

[0027] Specifically, the card plate 46 is "L" shaped, and the two sides of the slide plate 45 are fixedly connected to the limiting plate 451. The outer surface of the limiting plate 451 is slidably connected to the inside of the limiting groove 44.

[0028] In this embodiment, the matching design of the "L"-shaped card plate 46 and the positioning groove 63 can form a vertical mechanical limit when the sliding component 4 and the limiting component 6 are connected, preventing the bag opening from opening due to lateral force (such as transportation bumps), and significantly improving the stability of the closing structure.

[0029] Specifically, the card plate 46 matches the positioning groove 63, and the anti-slip strip 2 is a silicone rubber strip.

[0030] In this implementation scheme, the silicone rubber material has high elasticity and wear resistance, can maintain anti-slip performance for a long time, and is soft and does not easily damage the items inside the bag. At the same time, it enhances the structural strength of the inner wall of the kraft paper bag body 1 and extends its service life.

[0031] Specifically, after the opening of the kraft paper bag body 1 is closed, the surface of the magnet 42 is magnetically fixed to the surface of the iron plate 64.

[0032] In this embodiment, after the bag opening is closed, the magnetic attraction between the magnet 42 and the iron plate 64 can quickly achieve the initial sealing of the bag opening, which is convenient to operate. At the same time, the magnetic attraction and the mechanical locking of the card plate 46 form a double insurance, which improves the safety of the goods during transportation.

[0033] The working principle and usage process of this utility model are as follows: When in use, after placing the item inside the kraft paper bag body 1, the magnet 42 is attracted to the surface of the iron plate 64. Then, the pull rope 1 5 and pull rope 2 7 are directly pulled by hand. The pulling force of pull rope 1 5 on the slide plate 45 causes the slide plate 45 and the locking plate 46 to slide upwards, and the locking plate 46 slides inside the slot 62 until the outer surface of the locking plate 46 is inserted into the positioning groove 63. At this time, the sliding component 4 and the limiting component 6 are firmly connected together. The connection between the anti-slip strip 2 and the item effectively prevents the item from slipping. The kraft paper bag body 1 moves up and down inside, providing a good anti-slip effect and enhancing the stability of items inside the kraft paper bag body 1. When taking out items, stop applying force to the pull rope 1 5 and pull rope 2 7. Due to the weight of the slide plate 45 and the card plate 46, the card plate 46 will automatically disengage from the positioning groove 63. If it does not disengage automatically, applying downward force by pull rope 1 5 can also quickly make the card plate 46 automatically disengage from the positioning groove 63. Then, directly open the bag opening, the magnet 42 will disengage from the surface of the iron plate 64, the bag opening will open, and items can be quickly taken out.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
