Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, and more specifically, to a pesticide packaging bag that is resistant to crushing and tearing. Background Technology

[0002] Packaging bags are bags used to package various items, usually made of plastic, paper, cloth, or other materials. They are designed to protect items from damage, contamination, or deterioration during transportation, storage, and sales, and to provide convenient carrying and use. The design and printing of packaging bags are also very important and can be customized according to different product and brand needs to enhance product appeal and brand recognition. Pesticide packaging bags are bags used to package pesticide products. They typically have good sealing performance to prevent pesticide leakage and volatilization, ensuring the quality and safety of pesticides. They can resist the chemical corrosion of pesticides and prevent bag damage. Some packaging bags also adopt special leak-proof designs, such as sealing openings and zippers.

[0003] Chinese Patent Publication No. CN221368480U discloses a sealed packaging bag with a sealing clip, including a packaging bag body, an insert bone fixed to the right side of the opening of the packaging bag body, and a closing bone fixed to the left side of the opening of the packaging bag body; it also includes a sealing clip body, disposed on the upper outer side of the packaging bag body, with a pressing piece fixed on the sealing clip body, and ear plates symmetrically fixed on the outer side of the sealing clip body, with connecting rods connected to the ear plates, and magnets fixed on the connecting rods. This sealed packaging bag with a sealing clip uses a sealing clip structure, which can achieve sealing or opening of the packaging bag by sliding the sealing clip. Compared with manual sealing, the operation is more convenient and simple. In addition, with the magnetic structure, the position of the sealing clip can be locked after the packaging bag is sealed, thereby effectively preventing the sealing clip from sliding and opening the packaging bag during transportation and handling, thus ensuring the sealing effect of the packaging bag.

[0022] When packaging bags are subjected to external pressure, they may lose their original shape, become twisted, and may even rupture, causing the contents to leak out and pollute the surrounding environment. It may also damage the airtightness of the packaging bag, allowing air, moisture, or other substances to enter the bag and affect the quality of the contents.

[0023] Therefore, in order to improve the problem of packaging bags being easily broken when squeezed in related technologies.

[0024] Please see Figures 1 to 5A pesticide packaging bag designed to prevent crushing and rupture includes an outer bag body 1, an inner bag body 6, a reinforcing component 7, and a sealing component 8. The outer bag body 1 has a first through hole 14. The inner bag body 6 is disposed inside the outer bag body 1 and has a second through hole 15. The reinforcing component 7 is disposed on the outer bag body 1, and the sealing component 8 is disposed on both the outer bag body 1 and the inner bag body 6. The reinforcing component 7 is used to strengthen the outer bag body 1, and the sealing component 8 is used to seal the first through hole 14 and the second through hole 15.

[0025] Optionally, in some embodiments, please refer to Figure 5 The outer bag 1 includes a wear-resistant layer 2, a reinforcing layer 3, a sealing layer 4, and an anti-corrosion layer 5. The wear-resistant layer 2 is provided on the inner wall of the outer bag 1. The reinforcing layer 3 is fixedly provided on the side of the wear-resistant layer 2 away from the outer bag 1. The sealing layer 4 is provided on the side of the reinforcing layer 3 away from the wear-resistant layer 2. The anti-corrosion layer 5 is fixedly provided on the side of the sealing layer 4 away from the reinforcing layer 3.

[0026] This design allows the abrasion-resistant layer 2 to increase the abrasion resistance of the outer bag body 1, extending the service life of the packaging bag. The reinforcing layer 3 increases the overall strength of the packaging bag, making it more resistant to external forces such as tension, tearing, and puncture. This helps prevent the packaging bag from breaking or being damaged during use, protecting the contents. The reinforcing layer 3 can be combined with the sealing layer 4 to improve the reliability of the seal. It enhances the strength of the seal, preventing leakage and the entry of external substances. The reinforcing layer 3 can be made of different materials and structures to meet specific performance requirements, such as chemical corrosion resistance. The sealing layer 4 prevents air, moisture, and other contaminants from entering the packaging bag, thereby extending the shelf life of the goods and ensuring that liquids, powders, or other substances inside the packaging bag do not leak out, maintaining the integrity of the packaging. The anti-corrosion layer 5 slows down the entry of oxygen, prevents oxidation reactions, effectively inhibits the growth of bacteria and mold, resists moisture penetration, and prevents mold or rot caused by dampness.

[0027] Optionally, in some embodiments, please refer to Figure 1 and Figure 3 The reinforcing component 7 includes transverse reinforcing strips 71 and longitudinal reinforcing strips 72. Multiple transverse reinforcing strips 71 are fixedly arranged at equal intervals around the outer bag body 1, and multiple longitudinal reinforcing strips 72 are fixedly arranged around the outer bag body 1. A bubble strip 9 is provided in the gap between the outer bag body 1 and the inner bag body 6. One side of the bubble strip 9 is fixedly connected to the inner wall of the outer bag body 1, and the other side of the bubble strip 9 is fixedly connected to the outer peripheral surface of the inner bag body 6. Multiple bubble strips 9 are provided.

[0028] With this design, when staff use the packaging bag, the horizontal reinforcing strips 71 and vertical reinforcing strips 72 fixed on the outer periphery of the outer bag body 1 can increase the overall strength of the outer bag body 1, making it more able to withstand external pressure and weight, reducing the risk of breakage or damage, increasing the service life of the packaging bag, enabling it to hold more items or bear heavier loads, and improving stability. The bubble strip 9 can provide a good cushioning effect, protecting the internal pesticides from damage by collision and vibration, and can quickly recover its shape after being subjected to pressure, effectively dispersing the pressure applied to the packaged items. The bubble film can provide a certain heat insulation effect, helping to maintain temperature.

[0029] Optionally, in some embodiments, please refer to Figure 2 The sealing assembly 8 includes a discharge pipe 81 and a sealing cap 82. The discharge pipe 81 is disposed on the outer bag body 1 and communicates with the outer bag body 1 and the inner bag body 6 through a first through hole 14 and a second through hole 15. An external thread 12 is provided on the end of the discharge pipe 81 away from the outer bag body 1. An internal thread 13 is provided on the sealing cap 82. The sealing cap 82 is threadedly connected to the discharge pipe 81. A discharge port 11 is provided on the discharge pipe 81.

[0030] With this setup, when staff use the packaging bag and need to apply the pesticide inside, they first need to rotate the sealing cap 82. The internal thread 13 on the sealing cap 82 engages with the external thread 12 on the outer circumference of the outlet 11, disengaging the sealing cap 82 from the outlet pipe 81 and exposing the outlet 11. Then, the staff pours out the packaging bag, allowing the pesticide in the inner bag 6 to flow out of the outlet 11. The staff then pours out the required amount of pesticide, and finally, through the engagement of the external thread 12 and the internal thread 13, reconnects the sealing cap 82 to the outlet pipe 81, sealing the outlet 11. This prevents air, moisture, and other contaminants from entering the packaging bag, thus extending the pesticide's shelf life and ensuring that liquids, powders, or other substances inside the packaging bag do not leak out, maintaining the integrity of the packaging.

[0031] Optionally, in some embodiments, please refer to Figure 1 A handle 10 is provided at the top of the outer bag body 1.

[0032] Working principle: When using the packaging bag and needing to apply the pesticide inside, the worker first rotates the sealing cap 82. The internal thread 13 on the sealing cap 82 engages with the external thread 12 on the outer circumference of the outlet 11, disengaging the sealing cap 82 from the outlet pipe 81 and exposing the outlet 11. Then, the worker pours out the packaging bag, allowing the pesticide in the inner bag 6 to pour out from the outlet 11. The worker then pours out the required amount of pesticide, and finally, through the thread engagement of the external thread 12 and the internal thread 13, the sealing cap 82 is threadedly connected to the outlet pipe 81 to seal the outlet 11.
