ISO 9100-5:2005

Overview

ISO 9100-5:2005 - "Glass containers - Vacuum lug finishes - Part 5: 43 and 48 regular" defines the finish geometry for vacuum lug (lug-type) closures on wide‑mouth glass containers with nominal finish sizes of 43 mm and 48 mm regular. Published in 2005 as part of the ISO 9100 series, the standard gives the required profiles, cutter shapes and dimensional parameters needed to ensure reliable vacuum sealing and interchangeability between glass jars and corresponding closures.

Key topics and technical requirements

• Scope: Dimensions and design details for vacuum lug finishes of nominal sizes 43 mm and 48 mm regular for wide‑mouth containers.
• Finish geometry: Includes a defined cutter profile, thread construction and enlarged section views to control the finish form and moulding/cutting process.
• Thread parameters: Specifies thread construction elements such as pitch, thread profile and leads (see the standard’s Table 1 for full parameters).
• Sealing surface requirements: The sealing surface must be free of checks, dips, crizzles and other defects that could impair vacuum sealing.
• Ovality and concentricity: Ovality of finish diameters must be minimized; key diameters (E and T) should be concentric for proper cap engagement.
• Closure position and clearance: The cross‑hatched closure area and clearance limits are defined so glass will clear cap limits; contours below the H dimension and bead designs are optional but must provide sufficient free space.
• Tolerances: General tolerances apply as referenced to EN 22768‑1 (tolerances for linear and angular dimensions) when not individually specified.
• Drawing references: Figures and a dimensions table (cutter profile, section views, and Table 1) illustrate the required form and measurements.

Applications and who uses it

ISO 9100-5 is used wherever consistent vacuum lug finishes are required for wide‑mouth glass packaging:

• Glass container designers and manufacturers specifying finish geometry for jars and wide-mouth containers.
• Tooling and mould makers (cutter profile and lead design for mould opening).
• Closure and cap manufacturers ensuring compatibility with glass finishes.
• Packaging engineers and quality managers controlling finish tolerances and sealing performance.
• Procurement and regulatory teams requiring conformity across the supply chain for packaging interchangeability.
