Neck Finish Dimensions

"I" dimensions

The inner diameter of the bottle neck. Specifications require a minimum "I" to allow sufficient clearance for filling tubes. Linerless closures, with plugs and fitment require a controlled "I" dimension for a proper fit.

"T" dimensions

The outside diameter of the thread. The tolerance range of the "T" dimension will determine the mate between bottle and closure.

"E" dimensions

The outside diameter of the neck. The difference between the "E" and "T" dimensions divided by two determines the thread depth.

"H" dimensions

The height of the neck finish. Measured from the top of the neck to the point where the diameter "T" extends down, intersecting the shoulder.

"S" dimensions

Measured from the top of the finish to the top edge of the first thread. The "S" dimension is the key factor which determines the orientation of the closure to the bottle and the amount of thread engaged between bottle and cap.
