Prevent oil leakage

By changing the position of the slender rod, the rubber funnel realizes the concave and convex shift. When the bottle cover is screwed off, the slender rob at the bottle would move upward and the ball part takes the rubber funnel to form the upward protruding. As a result, the funnel protrudes out of the bottleneck for the convenience of pouring. When the bottle cover is screwed on, the ball part pushes the rubber into the bottle. The crevice is formed between the slender rod and the rubber funnel. As a result, the oil attached to the rubber funnel flows into the bottle along the funnel.
