Airless Assembly and Leak-Test Planning

Define the actual airless container assembly, test conditions and acceptance criteria before ordering packaging.

Containers only — no compounding or filling. Claims are limited to verified capability.

An airless bottle should be reviewed as a complete assembly: body, dispensing components, seals and the intended fill. A test performed on one component does not approve every possible combination.

Identify the assembly

Record the model, capacity and component versions. Ask which components come from Oulete and which come from specialist partners. Confirm how the package will be filled and closed, and share any assembly instructions with the team conducting the test.

Agree a test plan

State the fill, orientation, storage conditions, duration and handling sequence to be assessed. Define what counts as leakage and how observations are recorded. Add the dispensing checks needed by the product brief, including the expected use pattern.

Keep changes traceable

Retain the tested assembly and its results with the approved specification. A changed seal, closure or formula needs a review of whether the existing evidence still applies. Confirm the order-specific inspection requirements before production.

Browse airless bottles or arrange samples.

Put the specification to work

Prepare a sample request. The tool shows its inputs and limits before you use the result in a project brief.
