01Identify the neck before selecting a sprayer
For KRN-0561, request the neck finish drawing, dimensions and tolerances for the actual bottle specification. The 36mm width body footprint does not identify a neck size. Keep the closure method and filling equipment requirements in the same review.
02Check the complete height stack
This reference lists 98mm bottle-body height and 123mm overall height. Use those two published values to compare the pictured arrangement. Do not treat their difference as the exact cap height or a guarantee that a replacement pump will fit.
03Approve the decorative cap and its insert separately
A rounded cap profile is a styling reference, not a neck specification. Ask how the internal insert retains the cap, and check removal, seating and clearance on the proposed sprayer assembly.
04Define functional checks with the sample
Send the intended fill product and application requirements with KRN-0561. Ask which priming, spray, dip-tube, seal and leakage checks are appropriate for that fill and assembly. Agree the test method and acceptance criteria before approving the component set.
