Overview
ISO 9100-4:2005 is an international standard that specifies the dimensions and design requirements for vacuum lug finishes with a nominal size of 38 mm medium, specifically designed for wide-mouth glass containers. Developed by ISO in collaboration with the European Committee for Standardization (CEN), this standard is part of a broader series under ISO 9100 that addresses various vacuum lug finish sizes and types for glass packaging.
The importance of this standard lies in its role in ensuring compatibility, quality, and safety of glass containers used for vacuum sealing. Properly designed vacuum lug finishes are critical for maintaining vacuum integrity, protecting contents from contamination, and facilitating efficient packaging and distribution.
Key Topics
- Dimension Specifications: ISO 9100-4:2005 details precise measurements including diameters, thread parameters, and leads necessary for the 38 mm medium vacuum lug finish. Tolerances follow ISO 2768-1 to ensure consistent manufacturing quality.
- Thread and Seal Design: Features a specific thread construction and sealing surface requirements. The standard mandates sharp, perpendicular stop faces for optimal cap stopping function and defect-free sealing surfaces to avoid leakage.
- Quality Requirements: Emphasizes minimizing ovality in finish diameters and maintaining concentricity of critical dimensions to ensure proper vacuum performance.
- Interoperability: The standard supports compatibility with corresponding caps and closures, facilitating interchangeability and reducing packaging errors.
- Technical Collaboration: Based on CE.T.I.E. (International Technical Centre for Bottling and Packaging) data, this document reflects collaboration among industry experts for practical packaging solutions.
Applications
ISO 9100-4:2005 is essential for manufacturers, designers, and quality controllers involved in the production and use of wide-mouth glass containers that require vacuum sealing. Common applications include:
- Food and Beverage Packaging: Ensures airtight sealing for products such as preserves, sauces, and beverages, extending shelf life and preserving quality.
- Pharmaceutical Containers: Provides secure vacuum seals for glass containers used in medicinal products, protecting contents from contamination.
- Cosmetics Packaging: Maintains product integrity by preventing air exposure in jars and pots.
- Industrial Use: Supports packaging strategies where vacuum sealing in glass containers enhances product safety and user convenience.
Using ISO 9100-4:2005 helps optimize packaging processes, improve supply chain efficiency, and comply with international quality standards.
Related Standards
The ISO 9100 series includes multiple parts, each addressing different sizes or variations of vacuum lug finishes for glass containers, such as:
- ISO 9100-1: General requirements for vacuum lug finishes
- ISO 9100-2: 33 medium finish specifications
- ISO 9100-3: 38 regular finish specifications
- ISO 9100-5 to ISO 9100-14: Specifications for other finish sizes ranging from 43 mm up to 110 mm in various depths and profiles
Additionally, related standards like ISO 2768-1 define general tolerances critical to ensuring dimensional accuracy in manufacturing these finishes.
Summary
Adhering to ISO 9100-4:2005 guarantees precise dimensional standards for 38 mm medium vacuum lug finishes, promoting quality, safety, and compatibility in wide-mouth glass container packaging. It supports efficient vacuum sealing essential for protecting a variety of products across industries. Manufacturers and stakeholders benefit from harmonized design criteria that facilitate global trade and product integrity.
