(1) The structure of the glass bottle mouth is unreasonable (the bottle mouth is conical with a large top and a small bottom);

(2) The size of the stopper and the bottle are inconsistent (the inner diameter of the bottle mouth is small, and the diameter of the plug part of the rubber stopper is large);

(3) The silicone oil content of rubber plugs is high;

(4) The hardness of the rubber stopper is high;

(5) Improper strength and speed of the capping machine;

The specific cause of this is a conclusion based on actual measurements.
