Description

Technical Field

[0001] The utility model relates to a vent valve barrel cover device, in particular to a breathable valve barrel cover device for containing water-based products. Background Art

[0002] During the production and storage process, due to the insufficient consideration of the air permeability of the threaded joint and the imperfect detailed design of the exhaust channel for the 20L water-based metal inner-coated barrel, some of the original threads were a continuous line without a notch in the middle. When the base and the upper cover were screwed together too tightly, and when the base was under greater pressure, there was a possibility of locking the exhaust channel, resulting in frequent abnormalities, triggering quality abnormalities, involving many product types and a wide range. For example, the supplementary coating peeled off, the welds rusted, the barrel bulged, etc., and more than 90% of them were water-based paints. Therefore, due to the problems of the packaging barrels, there were many rework and filtration batches, and the rework manufacturing cost of the products was high. After investigation, mainly in the high-temperature summer season, as the storage time of the water-based products in the barrel extended, gas characteristics would be generated during the storage process, leading to swelling phenomena and the problem of weld rust.
