The anti-theft ring of the plastic barrel lid does not fall off and is closely related to the precision of the abrasive tool. If the precise parameters of the abrasive tool are not reached, it will directly cause the product size inconsistency, which directly affects the fit between the lid and the barrel mouth spiral.
The second reason why the anti-theft ring does not fall off may be directly related to the height of the barrel mouth. The height of the barrel mouth is too high, causing the lid to not be screwed to the end, directly affecting the anti-theft ring not being stuck in the anti-theft teeth.
Third, it is possible that the size of the anti-theft ring is too large and does not fit the anti-theft teeth.
