Container preform with threaded tamper evidence finish

A preform suitable for being blow-molded to form a container, the preform comprising:

• a finish portion including an opening to an interior of the preform and including a tamper evidence ledge;
• a neck portion adjacent to the tamper evidence ledge;
• a tapered portion configured to transition from a diameter of the neck portion to a diameter of a cylindrical portion comprising an elongate member that culminates in an end cap;
• one or more threads disposed on the finish portion and configured to threadably receive a cap, wherein the one or more threads share an adjacent intervening valley configured to allow passage of a thread disposed in the cap;
• and
• a handling valley disposed between the tamper evidence ledge and the one or more threads, the handing valley extending circumferentially around the finish portion and having a diameter less than a diameter of the intervening valley and nearer in dimension to a diameter of the neck portion on the opposite side of the tamper evidence ledge from the opening than to the diameter of the intervening valley.
