Overview

EN ISO 12821:2019 - Glass packaging - 26 H 180 crown finish - Dimensions specifies the geometric requirements for the 26 mm tall crown finish used on glass beverage bottles. Published by CEN/ISO, this standard defines the finish profile, bore and sealing-surface requirements, and general tolerances to ensure reliable sealing with metal crown caps (see EN 17177).

Key topics and technical requirements

• Scope: Dimensions and design details for the 26 H 180 crown finish intended for metal crown caps on beverage bottles.
• Finish height: The document applies to a 26 mm tall crown finish configuration.
• Bore and shoulder: The bore diameter measured at up to 3 mm down from the top is specified as between 18.0 mm (max.) and 16.5 mm (min.), with a minimum through bore of 15.5 mm.
• Crimping edge ("P" point): Detailed definition of the contact zone between the glass finish and the corrugated skirt of the cap. The recommended radius for optimum performance is between 0.5 mm and 0.8 mm (excluding the vertical mould joint).
• Sealing surface: The sealing surface must be smooth and free from defects; contact between the crown cap liner compound and the internal mould parting line of the finish should be avoided. Alternative detail views for the sealing surface are provided in Figures 4 and 5.
• Tolerances and references: General tolerances follow ISO 9058 (Glass containers - Standard tolerances for bottles). The standard supersedes EN ISO 12821:2015 and is based on Cetie data (GME 13.01).
• Non-returnable option: For one-way (non-returnable) bottles, certain diameter limits (≤ 18.5 mm) may be permitted by written agreement among bottler, glass manufacturer, and crown cap manufacturer.

Applications and users

• Glass manufacturers use EN ISO 12821:2019 to design and mould bottle finishes that are compatible with industry-standard crown caps.
• Cap manufacturers rely on the finish dimensions to design crown caps (see EN 17177) that crimp correctly and provide consistent sealing.
• Bottlers and beverage producers reference the standard when specifying containers to ensure seal integrity, production interchangeability, and supply-chain compatibility.
• Packaging engineers and quality control teams apply the standard for inspection, acceptance testing, and tolerance verification in production lines.

Related standards

• EN 17177 - Crown cap dimensions and design (26 mm diameter, 6 mm crown cap).
• ISO 9058 - Standard tolerances for bottles (normative reference used by EN ISO 12821:2019).
• Cetie GME 13.01 - Source data referenced in the ISO document.

EN ISO 12821:2019 supports consistent glass packaging design, reliable sealing with metal crown caps, and cross-industry interoperability - essential for beverage bottling and packaging supply chains.
