Packaging - Flexible tubes - Test method to determine the orientation of the flip-top cap

This document specifies a method to test the orientation of the flip-top cap on flexible cylindrical tubes [1].
It is applicable to aluminium, plastic and laminated tubes used for packing pharmaceutical, cosmetic, hygiene, food and other domestic and industrial products.

Verpackung - Tuben - Prüfverfahren zur Bestimmung der Ausrichtung des Klappdeckelverschlusses

Dieses Dokument legt ein Verfahren fest, um die Ausrichtung des Klappdeckelverschlusses an zylindrischen Tuben [1] zu prüfen.
Es ist anzuwenden für Aluminium-, Kunststoff- und Laminattuben zum Verpacken von Produkten der Pharmazie, der Kosmetik, der Hygiene, von Lebensmitteln und anderen Haushalts- und Industrieprodukten.

Emballage - Tubes souples - Méthode d'essai pour la détermination de l'orientation de l'obturateur à charnière

Le présent document spécifie une méthode d'essai visant à déterminer l'orientation des obturateurs à charnière montés sur des tubes cylindriques souples [1].
Il s’applique aux tubes en aluminium, en plastique et laminés, utilisés pour emballer des produits pharmaceutiques, cosmétiques, alimentaires, des produits d’hygiène et d'autres produits à usage domestique et industriel.

Embalaža - Prožne tube - Preskusna metoda za ugotavljanje orientacije zaskočnega pokrova

Ta evropski standard določa metodo za preskušanje orientacije zaskočnega pokrova na prožnih tubah.
Uporablja se za prožne aluminijaste, plastične in laminirane tube, namenjene pakiranju farmacevtskih, kozmetičnih, higienskih, prehrambenih ter drugih gospodinjskih in industrijskih izdelkov.
Pozor: Med sistematičnim pregledom leta 2020 so v Turčiji dali pripombo, da bo treba obseg področja uporabe verjetno omejiti na valjaste tube. O tem bo moral razpravljati tehnični odbor CEN/TC 261/SC 5/WG 26.

Overview

EN 16565:2022 is a European standard developed by CEN that defines a precise test method to determine the orientation of flip-top caps on flexible cylindrical tubes. This standard is applicable to various tube materials including aluminium, plastic, and laminated types, which are commonly used for packaging pharmaceutical, cosmetic, hygiene, food, and other domestic or industrial products. The methodology ensures consistent quality control in the manufacturing and packaging industries by standardizing the assessment of cap alignment.

The latest edition of EN 16565, published in 2022, supersedes the 2014 version, introducing updates to the test execution and reporting procedures. It supports manufacturers and quality inspectors in verifying the proper orientation of flip-top closures, which is critical for user convenience, aesthetic appeal, and product functionality.

Key Topics

• Scope and Applicability
  Covers flexible cylindrical tubes with flip-top caps made from aluminium, plastic, or laminated materials. Used for packaging various product categories, including pharmaceutical, cosmetic, hygiene, and food items.

• Test Principle
  Focuses on measuring the deviation of the cap hinge axis from the intended orientation using test equipment capable of accurate assessment. The test principle involves quantifying the maximum deviation in millimeters and degrees relative to tube diameter.

• Testing Equipment
  Any device that can reliably measure the orientation of the flip-top cap may be employed. The standard provides an example of a suitable test setup illustrating sample placement and deviation reading.

• Execution Procedure
  Samples of empty tubes with flip-top caps are tested for deviation. The maximum allowable deviation varies according to tube diameter, ensuring precise control at different sizes.

• Deviation Limits
  Specifies maximum permissible deviations both in millimeters and degrees for tube diameters ranging from 19 mm to 60 mm. Provides a conversion formula to calculate the degree deviation from millimeter measurements.

• Test Reporting
  Requires comprehensive test reports to include references to the standard, batch identification, number of units tested, defect counts, testing conditions, and tester information for traceability and quality assurance.

Applications

EN 16565:2022 is essential for quality assurance in the manufacturing and packaging sectors that utilize flexible tubes with flip-top caps. Its practical applications include:

• Pharmaceutical Packaging
  Ensures correct cap placement for secure sealing and patient-friendly access to medications.

• Cosmetics Industry
  Guarantees aesthetic consistency and functional performance of flip-top caps on tubes for creams, lotions, and other personal care products.

• Food Packaging
  Maintains hygiene and usability standards for flexible tube packages containing food substances such as sauces or pastes.

• Hygiene Products
  Supports packaging quality for items like toothpaste and gels requiring reliable flip-top closures.

• Industrial Goods Packaging
  Helps standardize packaging for lubricants, adhesives, and other products where the orientation of the flip-top cap impacts usability.

By applying this standard, manufacturers can reduce packaging defects, improve consumer satisfaction, and comply with European market requirements.
