ISO 9100-11:2005

Overview

ISO 9100-11:2005 - "Glass containers - Vacuum lug finishes - Part 11: 82 regular" is an international standard that specifies the geometric dimensions and finish details for a nominal 82 mm regular vacuum lug finish used on wide-mouth glass containers. Published in 2005 and prepared in collaboration with CEN and ISO/TC 63, this part of the ISO 9100 series defines the cutter profile, thread construction and dimensional parameters required to ensure compatible vacuum-cap closures and reliable sealing performance.

Key topics and requirements

• Scope and intent: Dimensioning of the vacuum lug finish for wide-mouth glass containers with nominal size 82 mm regular.
• Dimensional data: The standard provides detailed drawings (cutter profile, thread construction, enlarged section) and a tabulated set of dimensions including finish diameters (E, T, C), cutter inclination and thread parameters. Example values shown in the document include E = 77.60 mm, T = 80.75 mm, C = 71.05 mm and a cutter inclination α = 4°40'.
• Thread and lead parameters: Thread pitch, leads, and thread profile angles are specified to ensure mating compatibility with vacuum caps (T.P.I. and lead/angle values are provided in Table 1).
• Surface and concentricity requirements: The sealing surface must be free of checks, dips, crizzles and other defects that could impair sealing. Ovality of finish diameters must be minimized, and E and T diameters should be concentric.
• Closure position and clearance: Cross-hatched closure zones and minimum clearances between beads and closure areas are defined; optional contours below the H dimension and bead designs are allowed provided adequate free space is kept.
• Tolerances: Where not detailed, general tolerances apply in accordance with EN 22768-1.

Applications

• Design and manufacture of wide-mouth glass jars and containers intended for vacuum-sealed packaging (food preserves, pickles, bulk foods).
• Specification for mould/tooling designers and glassware producers to ensure consistent finish geometry.
• Reference for cap and closure manufacturers to design compatible vacuum lug caps and sealing liners.
• Quality control and inspection in bottling/packaging operations to verify finish conformity and sealing performance.

Related standards

• ISO 9100 series (other parts cover different finish sizes and types).
• EN 22768-1 (general tolerances for linear and angular dimensions).
• CETIE data sheets (historical reference used in preparation).

This standard is essential for engineers, tooling manufacturers, closure designers and packaging professionals working with vacuum lug finishes and wide-mouth glass containers.
