Overview
EN ISO 9100-9:2005 - Glass containers - Vacuum lug finishes - Part 9: 63, 66 and 70 deep (ISO 9100-9:2005) is a CEN-adopted ISO standard that defines the dimensional requirements for vacuum lug finishes on wide-mouth glass containers with nominal depths of 63, 66 and 70 mm. Published January 2005 (approved September 2004), the standard establishes cutter profiles, thread construction and tolerances to ensure compatibility between glass containers and vacuum closure systems.
Key topics and requirements
- Scope: Dimensions for vacuum lug finishes for wide-mouth containers (nominal depths 63, 66, 70 mm).
- Dimensional details: Clause 3 and Table 1 specify the finish geometry, cutter profile, thread parameters and permitted tolerances.
- Thread parameters: The standard specifies thread pitch and form for proper cap engagement (example: pitch shown as 1½ TPI in the table).
- Cutter profile and leads: Cutter inclination (α) is controlled and leads correspond to the cut-in profile; cutter leads of 4 mm are indicated in the document’s data table.
- Sealing surface quality: The sealing surface must be free of checks, dips, crizzles and other defects that could affect vacuum performance.
- Ovality and concentricity: Ovality of finish diameters should be minimized; diameters identified (E and T) should be concentric for reliable sealing and cap removal.
- Cap removal / cam-off point: The theoretical cam-off point is required to lie on the upper flank of the thread to assist cap removal.
- Design flexibility: Details not specified by the standard may be selected according to application; general tolerances reference EN 22768-1.
Practical applications
- Glass container manufacturers use this standard to design moulds and finish tooling for vacuum lug finishes so that containers accept industry-standard vacuum caps.
- Closure and cap designers rely on the defined thread and sealing geometries to produce compatible vacuum closures.
- Packaging engineers and bottlers use it to ensure reliable vacuum sealing for products such as wide-mouth jars, preserves and other vacuum-packaged foods.
- Quality inspectors and test labs refer to the dimensions and tolerance limits when verifying finish conformity and sealing performance.
- Mould makers and tooling suppliers apply the cutter profile and lead specifications when preparing finishing tooling.
Related standards
- EN 22768-1 (General tolerances for linear and angular dimensions) is cited for default tolerance practice.
- The document is based on CETIE data (GME 20-07:1995) and aligns with ISO/TC 63 glass container work.
