Overview

ISO 9100-2:2005 is an international standard developed by the International Organization for Standardization (ISO) that specifies the dimensions and design requirements for vacuum lug finishes sized 33 mm medium, primarily used on wide-mouth glass containers. This standard is part of the ISO 9100 series, which addresses various sizes and types of vacuum lug finishes for glass packaging. It is fundamental in ensuring compatibility, sealing efficiency, and product protection in packaging solutions involving glass containers with vacuum closures.

Key Topics

• Scope and Application
  The standard applies specifically to vacuum lug finishes with a nominal size of 33 mm medium, tailored for wide-mouth glass containers commonly used in food and beverage packaging.

• Dimensional Specifications
  ISO 9100-2:2005 details precise dimensions, including diameters, thread profile, pitch, and key tolerances required for manufacturing vacuum lug finishes. This includes parameters such as:

  • Diameter E and T (concentricity requirements)
  • Thread angle α and β
  • Pitch (threads per inch)
  • Critical tolerances to avoid simultaneous minimal diameter values

• Design Requirements
  The document sets forth critical design rules to ensure proper sealing and ease of use, such as:

  • Sharp thread stops to properly engage the cap
  • Smooth, defect-free sealing surfaces to maintain vacuum integrity
  • Maintenance recommendations to avoid wear on molds affecting thread shape
  • Minimization of ovalization to ensure concentricity and effective closure

• Reference to General Tolerances
  The standard refers to ISO 2768-1 for general dimensional and angular tolerances not specifically covered by the vacuum lug finish specifications.

Applications

ISO 9100-2:2005 is essential in the manufacturing and quality control processes of glass containers featuring vacuum lug finishes, especially those with wide mouths. Key applications include:

• Glass Food Packaging
  Glass jars and containers for preserving food products such as jams, sauces, and pickles rely on reliable vacuum lug finishes to maintain airtight seals and product freshness during distribution and storage.

• Beverage Bottles
  Containers for beverages that require vacuum sealing to preserve carbonation or freshness benefit from compliance with this standard to ensure caps fit securely and maintain pressure integrity.

• Pharmaceutical and Cosmetic Containers
  Wide-mouth glass containers used in these industries require precise finishes to guarantee product protection against contamination and leakage, making adherence to ISO 9100-2:2005 critical.

• Packaging Equipment Calibration
  The standard serves as a benchmark for manufacturers and packaging machinery developers to design compatible capping systems and molds, ensuring interoperability across industry supply chains.

Related Standards

The ISO 9100 series covers a wide range of vacuum lug finish sizes and types, facilitating standardized packaging solutions for glass containers. Related parts include:

• ISO 9100-1: General specifications for vacuum lug finishes
• ISO 9100-3 to 9100-14: Specifications for various other sizes, including 38 regular, 38 medium, 43 and 48 regular, 53 and 58 regular, up to 110 regular finishes
• ISO 2768-1: General tolerances for linear and angular dimensions that complement ISO 9100-2
• CEN/TC 261: European packaging standards harmonized with ISO 9100 series through cooperation agreements, ensuring global alignment

---

By adhering to ISO 9100-2:2005, manufacturers and users of vacuum-sealed glass containers can guarantee component compatibility, product safety, and quality consistency. This standard is a vital reference for glass container producers, cap manufacturers, packaging engineers, and quality control professionals focused on vacuum packaging solutions.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 9100-2 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 261, Packaging, in collaboration with Technical Committee ISO/TC 63, Glass containers, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
