Shampoo Cap (Wedge and Lever)

Explanation: This is the cap to my shampoo bottle. I may be completely wrong, but the actual cap is a class two lever (fulcrum is the end connected to the rest of the bottle, the load is in the middle where the cap locks, and effort is my finger pushing up on the opposite end of the fulcrum). Also, the white piece in the middle of the cap acts as a wedge and seals the bottle so that shampoo doesn't leak out.
