Current condition
Provide bottle material, dimensions and drawings of the neck, shoulder and base. Note how the empty bottle arrives, any damage and the starting contamination used in the trial.

Review bottle necks, shoulders, bases and stability for air rinsing. Plan nozzle access, handling and repeatable checks across the intended bottle formats.
Illustrative bottle-labelling scene.
Bottle geometry affects how air reaches the inside, how removed material leaves and how the empty bottle is supported. Include the smallest neck opening, awkward shoulders and least stable formats when comparing a proposed rinsing arrangement.
Provide representative normal and difficult bottles, not only nominal capacity. Record material, dimensions, neck opening, shoulder and base shape, then compare handling limits and the cleaning result across those formats. See the air-rinsing arrangement options.
Use bottle drawings and samples to compare nozzle access, gripping, guides and transfers. Check which formats can use the proposed orientation and where displaced debris will go. Keep bottle damage and stability observations separate from the agreed cleaning-result check.

Provide bottle material, dimensions and drawings of the neck, shoulder and base. Note how the empty bottle arrives, any damage and the starting contamination used in the trial.
Include every intended format and representative normal and difficult samples. The smallest opening, awkward shoulder or unstable base may reveal a handling or air-access constraint that nominal capacity does not show.
Identify changes to guides, holders or nozzles and how the correct setting is recorded. Repeat the cleaning-result and handling checks after a format change rather than assuming the first setup applies to every bottle.
Review the neck opening and shoulder shape with the nozzle position and actual airflow path. If particles remain around a shoulder, assess access and orientation before simply increasing pressure.
Include light containers and unstable bases in the infeed, guide and transfer review. Record the bottle flow and any damaged or failed examples through the intended route to the filler.
Check support during inversion and return where that arrangement is proposed. A grip suitable for a rigid round bottle may distort a lightweight shaped container; trial the relevant samples.
Assess bottle orientation, air delivery and collection together. Where inversion is impractical, ask how the nozzle and collection arrangement remove material rather than redistribute it inside the bottle.
List the guides, holders or nozzles that require adjustment and how settings are identified. Include access to inspect and clean the collection path; compare these requirements in the selection guide.
Repeat the agreed cleaning-result, transfer and restart checks on the changed format. Record failed or damaged bottles and the response to an unavailable air or extraction supply; agree the acceptance checks.
