EN ISO 9100-10:2005

Overview

EN ISO 9100-10:2005 (adopted by CEN as EN ISO 9100-10) specifies the design and dimensions of a vacuum lug finish with a nominal size of 77 mm (77 regular) for wide-mouth glass containers. The standard defines the finish geometry and key requirements that ensure proper function with vacuum lug closures, and it directs users to the illustrative Figures 1–3 and Table 1 for the detailed cutter profile, thread construction and finish section.

This document is produced by CEN/TC 261 in collaboration with ISO/TC 63 and is based on industry practice (CETIE data). It supports manufacturers, closure designers and quality engineers who require a consistent finish for sealing performance and interchangeability.

Key Topics

• Scope: Specifies the dimensions of a 77 mm regular vacuum lug finish for wide-mouth glass containers.
• Design references: The finish design and dimensions are shown in Figures 1–3 and Table 1 of the standard; these include the cutter profile, thread construction and an enlarged section view.
• Sealing surface requirements: The sealing surface shall be free of checks, dips, crizzles and other defects that may affect proper functioning.
• Ovality and concentricity: Proper system functioning requires minimizing ovality of the finish diameters. E and T diameters should be concentric to each other.
• Cutter profile and leads: Cutter inclination (α-angle) and lead start/end details are defined; optional features (e.g., riffles or beads) are allowed where needed for moulding or clearance, provided free space is retained for cap closure.
• Tolerances: For general tolerances not specified in the standard, see EN 22768-1 (General tolerances for linear and angular dimensions).

Applications

This standard is practical and widely applicable across the glass packaging industry:

• Ensures interchangeability between glass containers and vacuum lug closures from different manufacturers.
• Improves vacuum sealing reliability for products packaged in wide-mouth jars and pots requiring vacuum retention.
• Aids tooling and mould designers by providing a consistent cutter profile and finish geometry for production moulds.
• Supports quality control and inspection routines by defining the critical surfaces and concentricity requirements to verify.

Related Standards

• ISO/CEN packaging and glass container standards developed by ISO/TC 63 and CEN/TC 261.

For implementation, consult the figures and table contained in EN ISO 9100-10:2005 for exact profiles and the detailed dimensional data. The standard is intended to reduce variability in finish geometry and to ensure reliable performance of vacuum lug closures across the supply chain.
