A neck-finish reference helps start the bottle and closure review. It does not replace the interface drawing or prove that two independently sourced parts will seal together.
Documented finish references
These finishes appear in the company’s supplied range information. Confirm availability for the chosen model. A neck diameter printed in the product catalog is not a complete finish designation.
Send both sides of the assembly
Provide the bottle and closure drawings, including liners or other sealing parts. For a dispenser, include the contact materials and tube or pipette dimensions. Identify who will approve the assembled fit.
Test the finished combination
Agree application and opening requirements, leakage conditions and the relevant storage and transport checks. A matched code does not establish formula compatibility or dispensing performance.
Request a neck and closure review or see caps and closures.
Put the specification to work
Check the bottle and closure evidence. The tool shows its inputs and limits before you use the result in a project brief.
