    摘要： A screw-type bottle neck having areas of reduced wall thickness is provided. The bottle neck includes a neck opening having a neck opening axis, a neck interior surface, and a neck exterior surface. The neck exterior surface includes at least one spiral thread portion. The bottle neck has at least one area of first neck thickness having a first neck thickness, and at least one area of second neck thickness having a second neck thickness. The second neck thickness is greater than the first neck thickness. The difference between the first neck thickness and the second neck thickness allows for a substantial reduction in the amount of material required to manufacture the bottle neck.
