Description
Subtract closureDiameter from boreDiameter for nominalGap.
Container and coating geometry converts supplied dimensions, mass, and density into ideal clearances or thicknesses. Sterility, sealing, and functional performance require separate tests.
Subtract closureDiameter from boreDiameter for nominalGap.
When to use this tool
Use Pharmaceutical Container Closure Bench Clearance when you need one pharmaceutical packaging or film geometry term.
How to use the tool and how it works
- Enter boreDiameter, closureDiameter, toleranceBore, toleranceClosure. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read nominalGap, minimumGap, maximumGap. Use the output convention below.
Subtract closureDiameter from boreDiameter for nominalGap. Subtract or add both nonnegative tolerance allowances for minimumGap and maximumGap.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| boreDiameter | Bore Diameter | Required. Finite number; minimum 0. |
| closureDiameter | Closure Diameter | Required. Finite number; minimum 0. |
| toleranceBore | Tolerance Bore | Required. Finite number; minimum 0. |
| toleranceClosure | Tolerance Closure | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| nominalGap | Bore minus closure diameter, a diametral gap. | Required. Finite number. |
| minimumGap | Worst-case diametral gap after subtracting both supplied allowances. | Required. Finite number. |
| maximumGap | Maximum Gap | Required. Finite number. |

}Limitations and assumptions
- These are diametral gaps rather than radial clearances; sealing, deformation, sterility, and container-closure integrity are not evaluated.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use validated measurements and container or coating qualification methods for actual product decisions.
