Record the bottle and closure as a pair
Ask for the bottle drawing and closure drawing, and confirm the revision of each. Record the mating dimensions and the neck description supplied by the vendor. Keep a labeled sample pair so purchasing can distinguish it from visually similar alternatives. When a supplier proposes a replacement part, request the matching drawing and a fresh sample assembly before transferring the approved reference.
- Record material, capacity and supplier item code for the container.
- Record the insert, liner or overcap as separate parts where applicable.
Plan checks under real use
Have the filler review the sample with the proposed formula and closure. Observe how the assembly fills, closes, opens, dispenses and behaves after typical handling and storage. Record the conditions of each check along with any leakage, poor fit or change in output. Ask the technical team to decide which formal checks and tolerances the project requires based on the product and intended market.
- Record the filled sample reference, date and responsible reviewer.
- Keep open observations separate from the approved findings.
Translate findings into a purchase description
A hypothetical fit record might specify bottle B12, pump P04 and overcap C07 using the approved drawing revisions and the reviewed filled sample. That description lets a receiver match cartons and replacement components against the order. If either supplier changes a material, a dimension or the outer protection, mark the old approval as superseded only after the new sample is accepted.
- Ask the quote to repeat the approved part references.
- Keep a matched physical sample available to the filling site.
