Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmentally friendly biodegradable bags, specifically an environmentally friendly biodegradable bag bundling structure. Background Technology
[0002] Eco-friendly biodegradable bags are a type of plastic bag alternative designed to reduce environmental pollution. They are typically made of biodegradable or compostable materials that can break down in the natural environment, reducing long-term impacts on ecosystems.
[0003] When designing eco-friendly biodegradable bags, a binding structure is usually set at the opening to ensure the bag's airtightness and portability. For example, the most common method is to have two pull-out ropes inside the bag opening, which can be pulled to tighten the bag opening. However, this binding method lacks a continuous and strong binding force when tightened, which makes it impossible for the bag opening to be fully sealed. Moreover, the ropes used are usually nylon ropes, which have the problem of being difficult to degrade.
[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes an environmentally friendly biodegradable bag bundling structure. Summary of the Invention
[0005] The purpose of this invention is to provide an environmentally friendly biodegradable bag bundling structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An eco-friendly biodegradable bag strapping structure includes an eco-friendly biodegradable bag. A strapping strap storage box and a strapping bag positioning box are symmetrically arranged on both sides of the outer surface of the eco-friendly biodegradable bag near the opening. The side of the strapping strap storage box facing the strapping bag positioning box is open. A strapping strap is folded inside the strapping strap storage box. Pulling out the strapping strap allows it to move circumferentially along the outside of the strapping strap storage box and the strapping bag positioning box, thereby securing the bag along the lower side of the opening. The end of the strapping strap facing inwards from the strapping strap storage box has a fixed end, and the end facing outwards from the strapping strap storage box has a stretching end. A self-adhesive strip is attached to the stretching end of the strapping strap, and the self-adhesive strip is bonded to the strapping strap. The strapping is fixed in contact with the inside of the strapping storage box. The first end of the strapping is stretched outward along the opening of the storage box, allowing it to be stored inside. When in use, it is wrapped in a ring between the storage box and the positioning box. After the wrapping is tightened to a certain force, the self-adhesive strip is fixed to the strapping. Positioning tracks are provided on the outer surfaces of the storage box and the positioning box. When the strapping is wrapped along the outside of the storage box and the positioning box, it is repeatedly wrapped along the positioning tracks on both sides to prevent the strapping from slipping or shifting, thus ensuring the stability and long-lasting seal of the wrapping at the opening of the film.
[0008] Compared with the prior art, the beneficial effects of this utility model are: by setting a stretchable strap around the lower outer side near the opening of the eco-friendly biodegradable bag, and then using the adhesive properties of the self-adhesive strip at the end of the strap, in conjunction with the positioning track on the outside of the strap storage box and the bag positioning box, the eco-friendly biodegradable bag is stably and tightly bound around, ensuring that the eco-friendly biodegradable bag is fully closed while maintaining the durability and stability of the tight seal.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0018] Please see Figures 1-4 An environmentally friendly biodegradable bag binding structure includes an environmentally friendly biodegradable bag 10. A binding strap storage box 13 and a binding bag positioning box 14 are symmetrically arranged on both sides of the outer surface of the environmentally friendly biodegradable bag 10 near the opening. The binding strap storage box 13 is open on the side facing the binding bag positioning box 14. A binding strap 12 is folded inside the binding strap storage box 13. Pulling out the binding strap 12 allows it to move circumferentially along the outside of the binding strap storage box 13 and the binding bag positioning box 14, thereby binding and tightening the bag 10 along the lower side of the opening. A binding strap fixing end 15 is provided at one end of the binding strap 12 facing inwards from the binding strap storage box 13, and a binding strap stretching end 17 is provided at the other end facing outwards from the binding strap storage box 13. A self-adhesive strip 18 is provided at the end of the binding strap stretching end 17. The self-adhesive strip 18 and the binding strap 12... The strapping is fixed by adhesive contact. The end 15 of the strapping is fixed inside the strapping storage box 13. The stretching end 17 of the strapping is stretched outward along the opening of the strapping storage box 13, so that it can be stored inside the strapping storage box 13 when stored. When in use, it is wrapped in a ring between the strapping storage box 13 and the strapping bag positioning box 14. After the wrapping is tightened to a certain force, the self-adhesive strip 18 is controlled to adhere and fix the strapping 12. At the same time, positioning tracks 22 are opened on the outer surface of the strapping storage box 13 and the strapping bag positioning box 14. When the strapping 12 is wrapped along the outer side of the strapping storage box 13 and the strapping bag positioning box 14, it is wrapped repeatedly along the inside of the positioning tracks 22 on both sides to prevent the strapping 12 from sliding and deviating, thereby ensuring the stability and long-lasting sealing of the wrapping at the opening of the film 19.
[0019] In this embodiment of the invention, the environmentally friendly biodegradable bag 10 is provided with handles 11 on both sides of the opening to provide convenience for the user.
[0020] The strapping storage box 13 and the strapping bag positioning box 14 are both made of natural rubber, which has good degradability and a certain degree of hardness. By opening the positioning track 22 on its outer surface, it can provide a certain limiting function for the strapping path of the strapping 12, while also having a buffering effect and not damaging the environmentally friendly degradable bag 10 itself.
[0021] In one embodiment of the present invention, the bottom sides of the fixed end 15 of the strapping band are bonded to the outside of the environmentally degradable bag 10 inside the strapping band storage box 13 by adhesive fixing strips 16 to keep the end fixed. In the initial state, the strapping band 12 is stored inside the strapping band storage box 13 in a folded form. Once it is stretched outward by the self-adhesive strip 18, the strapping band 12 gradually expands outward. The strapping band 12 is made of biodegradable cotton rope or PLA material to ensure that it can effectively tighten and bind the environmentally degradable bag 10, while being consistent with the environmentally degradable bag 10, so that it can degrade smoothly and quickly.
[0022] In a preferred embodiment of the present invention, since one side of the cable tie storage box 13 is open, to ensure that the self-adhesive strip 18 can be stably placed at the opening when the cable tie 12 is stored inside the cable tie storage box 13, and to provide a convenient stretching point for the user during use, two closed adhesive strips 20 are symmetrically arranged on both sides of the opening of the cable tie storage box 13. An adhesive strip connecting block 21 is provided on the outer wall of the environmentally friendly biodegradable bag 10 corresponding to the closed adhesive strip 20. Simultaneously, two layers of film 19 are adhered to both sides of the self-adhesive strip 18. 9 is used to separate the adhesiveness of the self-adhesive strip 18. The two ends of the self-adhesive strip 18 extend to the part between the closed adhesive strips 20 and the adhesive strip connecting block 21 on both sides. At this time, the film 19 is squeezed and positioned by the adhesive strips 20 and the adhesive strip connecting block 21. At the same time, the self-adhesive strip 18 extends to the outside of the opening of the strapping storage box 13 to provide a stretching node for the user. After the environmentally friendly biodegradable bag 10 is tied, the film 19 on the self-adhesive strip 18 can be peeled off and fixed by the adhesiveness of the self-adhesive strip 18 to the strapping 12.
[0023] The working principle of this utility model is as follows: In the initial state, the strapping 12 is folded and stored inside the strapping 12 storage box 13. Then, the self-adhesive strip 18 at the end of the strapping 12 is separated on both sides by the film 19 and positioned by the adhesive strip 20 and the adhesive strip connecting block 21. When strapping is required, the self-adhesive strip 18 is stretched to unfold the strapping 12. During the strapping process, the strapping 12 is repeatedly wrapped in a ring along the positioning track 22 outside the strapping 13 and the strapping bag positioning box 14 until the opening of the environmentally degradable bag 10 is closed. Finally, the film 19 on the self-adhesive strip 18 is peeled off, and the strapping 12 is fixed by the adhesive strip 18 and the strapping 12, thereby fully closing the environmentally degradable bag 10.
[0024] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
