Overview

EN 17220:2019 (CEN) specifies dimensional requirements for flexible aluminium tube nozzles, including orifice diameters and metric thread forms. Prepared by CEN/TC 261 and published in August 2019, this standard supports consistent nozzle geometry across manufacturing and cap systems to help ensure interchangeability and tightness of the filled packaging system.

This standard applies to flexible aluminium tubes and complements terminology from EN 12374:2009 and dimensional references in EN 13046. It defines a set of nozzle shapes (A–E), dimensional tolerances and examples for common metric threads used in tube packaging.

Key Topics

• Scope and purpose: Defines nozzle dimensions, orifice and thread parameters for flexible aluminium tubes.
• Nozzle shapes: Standardized shapes A, B, C, D and E covering smooth-shoulder nozzles, cannula nozzles, applied plastic nozzles (with and without cannula) and membranes.
• Thread types and sizes: Lists metrical outer threads and associated orifice/height values for common sizes (examples include M7, M9, M11, M12×1,25, M13×1,5, M15×1,5, M20×1,5 and others as specified).
• Dimensional tables: Prescribed nominal diameters, orifice diameters, nozzle heights and tolerances are provided in tabular form for each shape.
• Tightness note: Primary objective is to ensure leak-tight performance with the mounted cap; minor deviations may be acceptable depending on cap design.

Applications

The standard is practical and directly useful for manufacturers, designers and quality engineers working with flexible aluminium tube packaging:

• Product design: Select standard nozzle geometries to match caps and dispensing requirements (creams, pastes, adhesives, food pastes, pharmaceuticals where applicable).
• Cap and closure development: Ensure cap threads and sealing features match EN 17220 nozzle dimensions for reliable compatibility.
• Tooling and fabrication: Set die and extrusion tooling parameters to meet the specified orifice and thread tolerances.
• Quality control: Use the defined dimensions and tolerances in inspection plans to verify production compliance and interchangeability.

Benefits include reduced assembly issues, predictable cap fit, consistent dispensing performance and improved leak prevention.

Related Standards

• EN 12374:2009 - Packaging - Flexible tubes - Terminology (referenced for terms and definitions).
• EN 13046 - Packaging - Flexible cylindrical metallic tubes - Dimensions and tolerances (informative reference for nominal tube diameters).

For manufacturers and specifiers, referencing EN 17220:2019 in procurement and design documentation helps ensure compatibility with the European CEN framework and promotes harmonized tube nozzle interfaces across suppliers.
