Waterproof anticorrosion breathable bolt for packaged bottle cap and manufacturing method of waterproof anticorrosion breathable bolt

Abstract

The invention relates to a waterproof anticorrosion breathable bolt for a packaged bottle cap and a manufacturing method of the waterproof anticorrosion breathable bolt. The bolt comprises an injection molding bolt body and a breathable film paster which is connected with the injection molding bolt body, wherein the outer diameter of the injection molding bolt body is in interference fit with an inner hole reserved in the packaged bottle cap; and the breathable film paster is arranged on an inner and outer gas convection channel of a container which is provided with the packaged bottle cap. The waterproof anticorrosion breathable bolt for the packaged bottle cap is designed to have a standard structure, so that the simplification of design and development of the packaged bottle cap of the container is facilitated, and the problem of inconvenience of use of the breathable bolt is solved; moreover, strong acid resistance and strong base resistance are improved, antioxidant capacity is improved, the problem that chemical solution leaks out of a pad is solved, and water resistance, dust resistance, oil resistance and breathable performance are improved, so that a packaging container reaches pressure balance through inner and outer gas convection of a modified membrane, and the transportation and storage safety of the container in a severe weather environment is improved.

Description

technical field [0001] The invention relates to a venting plug, in particular to a waterproof and anti-corrosion venting plug for packaging bottle caps and a manufacturing method thereof. Background technique [0002] Chemical liquids, such as bleach, hydrogen peroxide, peracetic acid, pesticides, cleaning agents, fungicides, etc., or strong acid and alkali solutions or powder packaging containers have very strict requirements. In order to solve this problem, some packaging containers used to use Airtight structure, the packaging container is sealed packaging, with the accumulation of gas in the container or the rise and fall of temperature, this kind of container will burst, collapse, cap cannot be opened or leak chemicals due to the imbalance of internal and external gas pressure. Safety production and transportation bring safety hazards. Inflated or sunken packaging will damage the corporate brand image and affect economic benefits. [0003] The existing technology is n...

AI Technical Summary

Problems solved by technology

[0002] Chemical liquids, such as bleach, hydrogen peroxide, peracetic acid, pesticides, cleaning agents, fungicides, etc., or strong acid and alkali solutions or powder packaging containers have very strict requirements. In order to solve this problem, some packaging containers used to use Airtight structure, the packaging container is sealed packaging, with the accumulation of gas in the container or the rise and fall of temperature, this kind of container will burst, collapse, cap cannot be opened or leak chemicals due to the imbalance of internal and external gas pressure. Safety production and transportation bring safety hazards

Inflated or sunken packaging will damage the corporate brand image and affect economic benefits

[0003] The existing technology is not effective in solving the problems of waterproof, dustproof, breathable, anti-oxidation, acid and alkali solution corrosion and other problems in chemical packaging containers. The disadvantage is that the performance of the original materials cannot meet the requirements of chemical liquids.

The point is that it cannot solve the pressure balance inside and outside the container and the leakage of chemical liquid
