Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bags, in particular to a leakage-proof pesticide packaging bag. Background Art

[0002] The main function of a pesticide packaging bag is to protect the pesticide from external factors and ensure its quality and effect. The existing patent document CN 210028558 U discloses a pesticide packaging bag, comprising a polypropylene film 1, a polypropylene film 2, a polyester propylene film 1 and a polyester propylene film 2, wherein the polypropylene film 1 is pressed onto the polypropylene film 2, and the polyester propylene film 1 is fixed to the lower end surface of the polypropylene film.

[0003] However, the pesticide packaging bag disclosed in the above patent document has ring bands 1, 2, 3 and 4 added to the packaging bag to prevent slipping when the packaging bag is torn along notch 1 or notch 2. However, when the pesticide packaging bag is squeezed by external force, leakage may occur. At the same time, when the pesticide is not used up at one time, it is not convenient to store it.

[0004] For this reason we have proposed a leak-proof pesticide packaging bag. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art. The existing patent document CN 210028558U discloses a pesticide packaging bag, on which a first ring belt, a second ring belt, a third ring belt and a fourth ring belt are added to prevent slipping when the packaging bag is torn along a first notch or a second notch. However, when the pesticide packaging bag is squeezed by an external force, leakage may occur. At the same time, when the pesticide is not used up at one time, it is inconvenient to store it. Therefore, a leakage-proof pesticide packaging bag is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0016] In the present application, when in use, first, the inner packaging bag serves as a direct container for pesticides, and its outer wall is sheathed with an outer packaging bag. The double-layer design provides an additional protective layer to prevent the pesticide from leaking due to external factors. The outer wall of the upper end of the inner packaging bag is fixedly connected to the inner wall of the upper end of the outer packaging bag to ensure the stability of the inner packaging bag. In the design of the drug outlet, a sealing component is provided to ensure the sealing of the pesticide when not in use. The sealing component includes a sealing block fixedly installed at the rear end of the inner wall of the drug outlet, and a sealing groove opened at the front end of the inner wall of the drug outlet. When the drug outlet is closed, the sealing block and the sealing groove are snap-fitted to form a tight sealing structure to effectively prevent the leakage of pesticides. In order to further enhance the anti-leakage performance of the packaging bag, a protective component is also provided. The protective component includes a first airbag and a second airbag respectively installed at the front and rear ends of the inner packaging bag. The airbags can be It acts as a buffer when squeezed by external force, protecting the inner packaging bag from damage, thereby preventing pesticide leakage. When in use, the user can pull the drawstring to pull open the sealing groove and the sealing block to allow the pesticide to flow out. The connecting tube on the connecting belt can be conveniently connected to the addition and pouring of pesticides, and the sealing end cap is used to seal the connecting tube when not in use to prevent pesticide leakage. At the same time, the transparent layer and scale design on the outer packaging bag provide an intuitive display of the pesticide storage amount, which is convenient for users to know the remaining amount of pesticide at any time. When the pesticide needs to be used up, the connecting belt can be torn open through the opening to facilitate pouring out all the pesticides in the inner packaging bag. A sealing head is provided under the first airbag and the second airbag, and the air pipe is sealed by hot melting. A groove is provided on the sealing head to facilitate tearing the sealing head to release the gas in the first airbag and the second airbag.

[0017] In the utility model, the leakage-proof pesticide packaging bag can effectively prevent pesticide leakage through the double-layer packaging bag design and the close cooperation of the sealing component, ensuring the safe storage of pesticides. The provision of the first airbag and the second airbag can play a buffering role when squeezed by external force, protecting the inner packaging bag from damage, and further improving the leakage-proof performance.

[0018] In the utility model, the leakage-proof pesticide packaging bag allows users to easily open the medicine outlet through the design of the drawstring, and the provision of the connecting belt and the connecting tube makes it convenient for users to pour out the pesticide in the pesticide packaging bag, and the sealing end cover is used to seal the connecting tube when not in use to prevent pesticide leakage, thereby improving the convenience of use. At the same time, the transparent layer and scale design on the outer packaging bag provide an intuitive display of the pesticide storage amount, which makes it convenient for users to understand the remaining amount of pesticide at any time and avoid waste.
