Overview
EN ISO 9100-5:2005 (published by CEN/ISO) defines the dimensional design for vacuum lug finishes with nominal sizes of 43 mm and 48 mm regular for wide‑mouth glass containers. The document provides the required cutter profile, thread construction and sectional views (Figures 1–3) and a tabulated set of dimension parameters (Table 1), all given in millimetres. The standard is intended to ensure compatibility between container finishes and vacuum closures and to promote consistent manufacturing practices across the supply chain.
Key Topics
- Scope and purpose: Specifies the finish geometry for vacuum lug finishes, nominal sizes 43 mm and 48 mm, used on wide‑mouth glass containers.
- Figures and table: Includes Figures 1–3 (cutter profile, thread construction, enlarged sections) and Table 1 with the critical dimension sets required for design and inspection.
- Surface and concentricity requirements: The sealing surface shall be free of checks, dips, crizzles and defects affecting function. The standard emphasizes minimizing ovality and keeping key diameters concentric for proper closure operation.
- Design flexibility: Details not explicitly specified may be selected according to application; general tolerances refer to EN 22768-1.
- Origins and references: Based on CETIE data (GME 20-03:1995) and prepared by CEN/TC 261 in collaboration with ISO/TC 63.
Applications
This standard is directly applicable to professionals and organizations involved in the design, manufacture and quality control of glass containers and closures:
- Glass container designers and mould makers: Use the finish geometry and cutter profile guidance to develop tooling for 43 mm and 48 mm vacuum lug finishes.
- Closure and cap manufacturers: Ensure closure thread and lug designs match the dimensional envelope and sealing interface shown in the standard.
- Quality and inspection teams: Reference the figures and Table 1 when verifying finish dimensions, sealing surface condition, and concentricity.
- Packaging engineers and OEMs: Specify EN ISO 9100-5:2005 where vacuum lug compatibility and reliable vacuum sealing are required for product protection.
Practical benefits include improved interchangeability between suppliers, fewer sealing failures in vacuum applications, and clearer criteria for production acceptance.
