EN ISO 9100-11:2005 PDF

Overview

EN ISO 9100-11:2005 - Glass containers: Vacuum lug finishes - Part 11: 82 regular specifies the geometric design and dimensional requirements for a vacuum lug finish with a nominal size of 82 mm (regular) intended for wide-mouth glass containers. Published by CEN and aligned with ISO/TC 63, this standard defines the finish geometry that ensures reliable sealing and compatibility with vacuum lug closures used in food, beverage and other packaged products requiring vacuum sealing.

Key topics and technical requirements

• Scope and intent: Defines the finish dimensions and form for the 82 mm vacuum lug finish for wide-mouth glass containers.
• Dimension drawings: Detailed Figures 1–3 illustrate the cutter profile, thread construction and an enlarged section (A–A) showing sealing and clearance areas.
• Tabulated dimensions: Table 1 lists the specified diameters, cutter leads and thread parameters (including pitch and threads-per-inch where applicable).
• Cutter profile and leads: The standard prescribes the cutter inclination (α angle) and how lead-in/lead-out profiles relate to mould opening requirements.
• Thread construction: Parameters for the lug threads (pitch, T.P.I., angles) are given so caps and closures mate correctly.
• Sealing surface quality: The sealing area must be free of checks, dips, crizzles and other defects that could impair vacuum sealing.
• Form control: Ovality of finish diameters should be minimized and critical diameters (E and T) should be concentric to ensure consistent closure fit and vacuum integrity.
• Closure position and clearance: The C diameter and H height define closure seating; adequate clearance between any mould beads and the closure seating area is required.
• Tolerances: Unless otherwise specified, general tolerances apply as per EN 22768-1.

Practical applications and users

This standard is directly applicable to:

• Glass container designers and manufacturers producing wide-mouth jars and pots with vacuum lug finishes.
• Tooling and mould makers who must produce cutter profiles and finish geometries to the specified dimensions.
• Closure and cap manufacturers designing vacuum lug closures to mate with 82 mm finishes.
• Packaging engineers, quality control and procurement teams specifying interface compatibility and inspection criteria for vacuum-sealed glass packaging used in food, beverage, pharmaceutical and cosmetic products.

Using EN ISO 9100-11:2005 helps ensure interchangeability, reliable vacuum sealing and consistent production quality across suppliers.
