In brief

Supply representative bottles and caps for each format. Review how the bottle is supported and the cap is gripped without slipping or distorting the container.

Include the smallest, largest and awkward-to-grip formats. Do not assume that a fixture suitable for one bottle and cap combination will suit every other combination.

On the production floor

Turn your production information into clearer decisions — Closure Torque Measurement

Bring representative bottles and caps to the fixture review. Check support, grip and access for each format before comparing measurements.

What to record

Bottle and Closure Formats: condition, range and effect on your process

Current condition

List the bottle and cap references, dimensions or drawings available, and the way each format is currently restrained and gripped.

Realistic range

Include normal and difficult bottle shapes, closure types and access restrictions, using real samples rather than a nominal drawing alone.

Effect on the system

Record which fixture, grip or procedure changes each format needs and how those changes will be checked.

Before you contact us

Five questions about bottle and closure formats for your application

  1. Who can confirm this information?Identify the person responsible for bottle and closure formats in production, quality, engineering or operations.
  2. How representative is the sample?Include age, supplier, batch, environment and upstream process state where they affect closure torque measurement.
  3. What is the difficult condition?Include awkward bottle support, restricted cap access or other representative cases that make the proposed test method difficult.
  4. How will you judge the result?Agree the method, repetitions, acceptable range, result record and the response if the observed result falls outside the agreed range.
  5. What else must be coordinated?Your final closure torque measurement scope must also account for fixture access and format-change procedure, result review and exception handling, current regulations and the conditions at your site.

Question 1

Bottle and Closure Test Conditions

Use the same conditioning time and method when comparing the effect of different bottle and cap formats.

Question 2

Bottle and Closure Formats

Supply the smallest, largest and unusual bottle and closure formats, including shapes that restrict grip or access.

Question 3

Measurement Event, Range and Units

Define the measurement event and expected range for each approved bottle and cap combination.

Question 4

Sampling and Result Records

Identify each format in the result record so readings from different combinations are not mixed unintentionally.

Question 5

Fixture Access and Format Changes

Review how the bottle is supported without slipping or distortion and how each cap can be gripped.

Question 6

Result Review and Exception Handling

Agree which format changes need a method review or repeat trial, and who will approve the resulting records.
