Most containers we supply are a continuous thread neck finish. The threaded neck allows metal or plastic closures to rotate until the closure fits against the bottle’s shoulder or neck bead. The neck finish of the bottle will determine the closure style you can use (i.e. 20 -400)
Determining a Plastic Container Thread Finish
When a container finish is designated as 24-410, it means that the diameter across the outside of the threads is approximately 24mm. The 410 designates a specific style of thread.
What About the Letters?
When you receive technical drawings of our bottles and jars, the closure area will have several dimensions listed to help you know more about the tolerances of a particular bottle’s neck.
Give us a buzz to learn more about these important specifications.
