[0002] High-risk agricultural chemical product packaging barrel is used for packaging pesticides, liquid biological fertilizer, strong acid and strong base, bleaching agent and pipeline dredging agent etc.Currently, the cover of these packaging barrels is generally provided with a breather plug product with a breather film, although the breather film has the characteristics of waterproof and oil-proof, but the viscosity of such high-risk agricultural chemicals is generally high, and during transportation, it is very easy to splash on the surface of the breather film, thereby reducing the breather pressure relief effect due to the adhesion of the liquid to the breather film.

[0003] The breather plug products on the market have the following shortcomings: 1. Breather plug product without bottom cover: without bottom cover protection, liquid splashing during transportation, breather film is easy to be adhered by agricultural product and reduce the breather pressure relief effect; 2. Breather plug product with bottom cover: although it has bottom cover protection, it can block most of the liquid splashing, but due to the large hole around the breather plug, it does not have side protection function, so in some violent shaking process, part of the liquid will still splash on the breather film, thereby reducing the breather pressure relief effect due to the adhesion of the liquid to the breather film.

[0004] At present, many companies want to develop a breather film product that can prevent viscous liquid from adhering to the surface of the film from the perspective of the breather film, but the effect is not very ideal. Therefore, the inventor designs a new breather plug structure that can avoid viscous liquid from contacting the surface of the breather film as much as possible, thereby achieving the purpose of preventing liquid splashing.

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] Please refer to Figures 1-5 A packaging application liquid splash-proof breathable plug assembly, comprising inner plug body 1 and plug cover 3 that can be buckled together, the material of inner plug body 1 and plug cover 3 is PP (polypropylene) plastic or HDPE (high-density polyethylene) plastic, inner plug body 1 is composed of plug column 1a, platform 1b and claw 1c;

[0029] Plug cover 3 is composed of outer cover 3a, inner clamping groove 3b, cover hole 3c and cover bottom 3d, outer cover 3a can cover the four sides of inner plug body; outer cover 3a can block waterproof breathable membrane 2, prevent liquid from splashing on waterproof breathable membrane 2 from the side of the breathable plug;

[0030] One side of platform 1b is fixedly connected with plug column 1a buckled with the bottle cap, plug column 1a is a hollow structure, and the hollow axis center corresponds with the axis center of the breathable hole opened on the bottle cap; waterproof breathable membrane 2 is welded on the other side of platform 1b, the diameter of platform 1b is greater than the diameter of plug column 1a, the middle of platform 1b is provided with a cross or a mesh hole, for welding waterproof breathable membrane 2; claw 1c is fixedly arranged on the platform 1b at the edge of waterproof breathable membrane 2, the number of claw 1c is not less than two, and the top of each claw 1c is provided with a reverse buckle for riveting with clamping groove 3b;

[0031] Waterproof breathable membrane 2 can be composed of the following three structures:

[0032] Structure 1: ePTFE (expanded polytetrafluoroethylene) layer + PO (polyolefin) non-woven fabric layer;

[0033] Structure 2: ePTFE (expanded polytetrafluoroethylene) layer + PP (polypropylene) transparent mesh layer;

[0034] Structure 3: pure ePTFE (expanded polytetrafluoroethylene) film layer;

[0035] Therefore, the surface of the waterproof and breathable film 2 has oleophobic and hydrophobic properties;

[0036] The inner wall of the outer cover 3a is provided with an inner clamping groove 3b that can be riveted with the clamping pawl 1c. The inner clamping groove 3b is located inside the plug cover 3 in a whole circle, without the need for positioning, facilitating riveting with the clamping pawl 1c. The bottom of the outer cover 3a is provided with a cover hole 3c, which is used for the liquid to flow out along the bottom cover hole 3c once the liquid enters the inside of the breathable plug. The bottom of the outer cover 3a protrudes into the inside of the plug cover 3 to form a cover bottom 3d, preventing the liquid entering the breathable plug from depositing inside the breathable plug. The diameter of the 3d is greater than the diameter of the breathable film, so that even if the liquid splashes through the cover hole 3c, it cannot directly contact the waterproof and breathable film 2.

[0037] The number of clamping pawls 1c is consistent with the number of cover holes 3c, and the width of the clamping pawl 1c is less than the cover hole 3c. In this way, the clamping pawl 1c can be prevented from being blocked at a certain angle to cover the cover hole 3c. Even if the liquid enters the inside of the breathable plug, the liquid can flow out along the bottom cover hole 3c, achieving the purpose of preventing liquid splashing.

[0038] The working principle diagram of the breathable plug product is that the plug column 1a of the breathable plug is installed into the installation groove of the barrel cover, and the top end of the cover has a breathable hole. When the internal pressure of the bottle body is higher than the external atmospheric pressure, the air inside the bottle body can be discharged from the bottle body through the waterproof and breathable film 2 and the breathable hole. When the internal pressure of the bottle body is lower than the external atmospheric pressure, the external air can enter the bottle body through the breathable hole and the waterproof and breathable film 2. In this way, the pressure balance of the bottle body is controlled.

[0039] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
