Description

Technical Field

[0001] The utility model relates to the technical field of kraft paper bags, and particularly relates to an environment-friendly kraft paper bag. Background Technique

[0002] Due to the naturalness and degradability of its production materials, the kraft paper bag has become an excellent substitute for plastic bags. Kraft paper is a kind of paper made from wood pulp or other plant fibers, which has high durability and load-bearing capacity. At the same time, it can be naturally degraded after use, reducing the impact on the environment. In addition, the production process of kraft paper bags is also relatively environmentally friendly, reducing the dependence on harmful chemical substances.

[0003] An environment-friendly kraft paper bag disclosed in Chinese Patent with the publication number CN219613252U includes a bag body. A decorative box is clamped on the surface of the bag body. A strengthening component is installed inside the bag body. A plurality of lifting components are connected to the top of the bag body. By providing the bag body, the strengthening component, and the decorative box, the structure strength of the kraft paper bag can be enhanced, the service life of the kraft paper bag can be increased, and the usage requirements of users can be met. By providing the lifting components and the connecting rings, the lifting postures of different people in different situations can be satisfied, the practicability of the kraft paper bag can be increased, and the usage experience of users can be improved. By providing the cup sleeve and the bearing component, the usage function of the kraft paper bag can be improved, and the usage scenario of the kraft paper bag can be improved.

[0004] Regarding the above related technologies, there are some deficiencies in this device. In the actual use process, the hand-held function of the kraft paper bag is realized through the lifting components. However, the position of the lifting rope on the lifting components is fixed and the length is not adjustable. This means that users can only carry the kraft paper bag by hand and cannot adjust the length of the lifting rope for carrying it on the shoulder. As a result, the carrying method of the kraft paper bag is relatively single, which makes it less convenient and comfortable to use in some cases, especially when it is necessary to free the hands. Therefore, it is necessary to provide an environment-friendly kraft paper bag to solve the above technical problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an environment-friendly kraft paper bag to solve the problems raised in the above background technique.

[0015] Preferably, the cup holder is in a cylindrical shape, and the top of the cup holder is of an open structure.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] 1. Through the combined use of the paper bag body, fixing holes, lifting rope, first connecting block, second connecting block, knob, threaded groove and threaded column, the kraft paper bag can be adjusted at the front and back positions of the paper bag body through the lifting rope, realizing double-strand hand-held and single-strand shoulder-carried, allowing users to switch between the two ways of hand-held and shoulder-carried at any time according to needs, being convenient and comfortable to use. At the same time, the lifting rope has a quick-release structure between the first connecting block and the second connecting block, facilitating the disassembly, assembly and replacement of the lifting rope, and having high practicability.

[0018] 2. By using the combination of the carrier frame, the external connecting pipe, the threaded hole, the external thread, the guiding pipe and the external discharge hole, when the paper bag body is in use, a carrier frame is placed at the bottom inside it, which can increase the load-bearing capacity of the paper bag body and make it more durable. At the same time, the cup carried by the user can be directly placed on the cup holder inside the paper bag body to ensure the stability of the cup placed inside the paper bag body. The cup holder can not only hold the cup, but also directly place the folded umbrella. If there is water on the umbrella, it will directly drip into the inside of the cup holder and be discharged through the guidance of the external connecting pipe. Finally, it is discharged to the outside of the paper bag body through the external discharge hole in time, avoiding the accumulation of rainwater inside the paper bag body and keeping the inside dry. In addition, the cup holder is installed on the carrier frame inside the paper bag body through the threaded connection between the external thread on the external connecting pipe and the threaded hole, making the disassembly and assembly of the cup holder simple and convenient for the user to flexibly assemble and use according to needs.

[0019] 3. By using the combination of the anti-slip sleeve and the anti-slip layer, during the use of the lifting rope, two anti-slip sleeves are movably installed on the lifting rope. Whether it is carried by hand or on the shoulder, it reduces the direct friction of the lifting rope on the user's hand or shoulder, thereby improving the comfort during the carrying process. At the same time, through the setting of the anti-slip layer on the inner surface of the anti-slip sleeve, the friction force between the anti-slip sleeve and the lifting rope is increased, making the stability of the anti-slip sleeve adjusted at a certain position on the lifting rope, preventing sliding or displacement.

[0030] Please refer to Figures 1 - 5 , an embodiment provided by the present utility model:

[0031] An environment-friendly kraft paper bag, which includes:

[0032] A paper bag body 1, symmetrically distributed fixing holes 2 are opened on the upper sides of the front and back of the paper bag body 1. A lifting rope 4 is arranged on the paper bag body 1 through the fixing holes 2. A second connecting block 6 is fixedly installed at one end of the lifting rope 4, a first connecting block 5 is fixedly installed at the other end of the lifting rope 4. A knob 10 is rotatably installed at one end of the first connecting block 5, a threaded column 12 is fixedly installed at the end of the knob 10 away from the first connecting block 5, a threaded groove 11 is opened at one end of the second connecting block 6, and the threaded groove 11 is threadedly connected with the threaded column 12.

[0033] A carrier rack 9 is provided below the interior of the paper bag body 1, and the carrier rack 9 has a concave structure. The concave structure makes the carrier rack 9 fit more closely to the bottom of the paper bag, making the paper bag more stable when placed, reducing deformation or inclination of the paper bag during use, and enhancing its safety in use.

[0034] In one embodiment, an outer discharge hole 20 is provided on one side of the bottom of the paper bag body 1. A threaded hole 16 corresponding to the position of the outer discharge hole 20 is provided at the bottom of the carrier rack 9. A guiding tube 19 is fixedly installed outside the threaded hole 16 at the bottom of the carrier rack 9, and the guiding tube 19 is inserted into the outer discharge hole 20. A cup holder 8 is provided on one side inside the carrier rack 9. An outer connecting tube 15 is fixedly inserted through the bottom of the cup holder 8. An external thread 18 is provided on the outer wall of the outer connecting tube 15, and the outer connecting tube 15 is threadedly connected to the threaded hole 16 through the external thread 18. By inserting the guiding tube 19 into the outer discharge hole 20, the stability of the placement of the carrier rack 9 is improved.

[0035] In one preferred embodiment, an anti-slip sleeve 7 is movably sleeved on the outer wall of the lifting rope 4, and the number of anti-slip sleeves 7 is two.

[0036] In one embodiment, an anti-slip layer 14 is provided on the inner wall of the anti-slip sleeve 7, and the material of the anti-slip layer 14 is rubber. The rubber material has good friction, which can effectively increase the friction between the anti-slip layer 14 and the lifting rope 4, thereby enhancing the stability of the anti-slip sleeve 7 and preventing sliding or displacement during use.

[0037] In one preferred embodiment, a number of equally spaced and uniformly distributed grooves 13 are provided on the outer wall of the knob 10, which can provide better friction, enabling the user to hold the knob 10 more firmly when rotating, reducing the possibility of sliding, and facilitating the quick installation and disassembly of the lifting rope 4.

[0038] In one embodiment, a first circular metal crimping buckle 3 is provided on the fixing hole 2, and a second circular metal crimping buckle 17 is provided on the outer discharge hole 20, which is used to reinforce the edge of the hole-shaped structure on the kraft paper bag, enhance its durability and prevent wear or tearing, and ensure that the structure of the paper bag is more firm.

[0039] In one preferred embodiment, the cup holder 8 is in a cylindrical shape, and the top of the cup holder 8 is an open structure, making the cup body of the cup holder 8 in a closed state, avoiding the liquid leaking into the interior of the paper bag body 1 inside the cup holder 8.

[0040] The working principle of the present utility model is as follows: When the paper bag body 1 is in use, one end of the lifting rope 4 is passed through the inside of the left two fixing holes 2 from the back of the paper bag body 1, then led out from the front of the paper bag body 1 and passed through the right two fixing holes 2 and back to the back of the paper bag body 1. At this time, both ends of the lifting rope 4 are located at the back position of the paper bag body 1. Subsequently, the first connecting block 5 and the second connecting block 6 on both ends of the lifting rope 4 are connected, aligning the first connecting block 5 with the second connecting block 6, and rotating the knob 10. The rotation of the knob 10 drives the threaded column 12 to rotate, causing the threaded column 12 to be screwed into the internal threaded groove 11 of the second connecting block 6, completing the fixation between the first connecting block 5 and the second connecting block 6, and making the lifting rope 4 form a closed loop. At this time, the installation of the lifting rope 4 on the paper bag body 1 is completed. According to the user's usage habit, when the user needs to carry it by hand, directly pull the lifting rope 4 to make the length of the lifting rope 4 in the front and back of the paper bag body 1 in a closed-loop state the same. At this time, there is a U-shaped handle structure on both the front and back of the paper bag body 1. Then, turn the lifting rope 4 outside the paper bag body 1 upward and hold the two U-shaped structures by hand, which realizes the hand-carrying function of the paper bag body 1. When it is necessary to carry it on the shoulder, directly pull the lifting rope 4 to make the lifting rope 4 concentrated on one side of the paper bag body 1, and the lifting rope 4 changes from double-strand to single-strand. At this time, the overall operating length of the lifting rope 4 becomes longer, and the user can directly complete the shoulder-carrying of the paper bag body 1 through the single-strand lifting rope 4. This kraft paper bag can be carried by hand with double strands and on the shoulder with a single strand by adjusting the position of the lifting rope 4 on the front and back of the paper bag body 1, allowing the user to switch between the two methods of carrying by hand and on the shoulder at any time according to needs, which is convenient and comfortable to use. At the same time, the lifting rope 4 is easy to disassemble and replace through the quick-release structure between the first connecting block 5 and the second connecting block 6, and has high practicability.

[0041] When the paper bag body 1 is in use, a carrier 9 is placed at the bottom inside it, which can increase the load-bearing capacity of the paper bag body 1, making it more durable. At the same time, the cup carried by the user can be directly placed on the cup holder 8 inside the paper bag body 1 to ensure the stability of the cup placed inside the paper bag body 1. The cup holder 8 can not only hold cups but also directly place the folded umbrella. If there is water on the umbrella, it will directly drip into the inside of the cup holder 8 and be discharged through the guide of the external connecting pipe 15, and finally be discharged to the outside of the paper bag body 1 in time through the external discharge hole 20, avoiding the accumulation of rainwater inside the paper bag body 1 and keeping the inside dry. In addition, the cup holder 8 is installed on the carrier 9 inside the paper bag body 1 through the threaded connection between the external thread 18 on the external connecting pipe 15 and the threaded hole 16, making the disassembly and assembly of the cup holder 8 simple and convenient for the user to flexibly assemble and use according to needs.
