Remark
“H?Dimension: The height of the neck finish. Measured from the top of the neck to the point where the diameter, “T? extends down and intersects the shoulder.

Neck Dismension“S?Dimension: Measured from the top of the finish to the top edge of the first thread. The “S?dimension is the key factor in determining the orientation of the closure to the bottle and the amount of thread engagement between the bottle and cap.

“I?Dimension: The inner diameter of the bottle neck. Specifications require a minimum “I?to allow sufficient clearance for filling tubes. Linerless closures, with a plug or land seal, and dispensing plugs and fitments require a controlled “I?for a proper fit.

“T?Dimension: The outside diameter of the thread. The tolerance of the “T?dimension determines the mate between bottle and closure.

“E?Dimension: The minor diameter measured across the root of the threads.
