Dieses Verschlussmundstück ist dafür ausgelegt, ausschließlich Kunststoffverschlüsse mit Originalitäts-sicherung einschließlich Varianten mit Anbindungselement aufzunehmen.
Emballage - Récipients en plastique rigide - Bague PET 29/25 (12,6)
Le présent document spécifie la conception et les dimensions de la bague à vis de 29 mm à trois (3) filets pour le bouchage des eaux plates et des boissons non carbonatées.
Il est applicable aux bagues désignées « bagues PET 29/25 (12,6) ». La dimension (12,6) est la hauteur, en millimètres, entre le sommet de la bague et le bas de la collerette de préhension.
La bague peut être utilisée pour le remplissage aseptique et pour le remplissage avec utilisation d’azote sous pression, la surpression interne n’excédant pas 1 bar.
Cette bague est prévue pour recevoir uniquement une capsule en plastique avec témoin d’effraction, y compris une capsule restant attachée à la bouteille lors de l’utilisation.
Embalaža - Toge plastične posode - PET-grla 29/25 (12,6)
Ta evropski standard določa zasnovo in mere za navojno grlo s premerom 29 mm ter trojnim (3) začetkom navoja za negazirano vodo in negazirane napitke. To grlo je namensko grlo PET 29/25 (12,6).
To grlo je mogoče uporabljati za aseptično polnjenje in polnjenje z dodajanjem dušika (notranji nadtlak nižji od največ 1 bara). Mera (12,6) je višina v milimetrih od vrha grla do dna podpornega okrajka.
Grlu se lahko doda le plastičen čep, ki varuje pred nedovoljenim odpiranjem. Pri prvem odpiranju se obroček, ki varuje pred nedovoljenim odpiranjem, loči od lupine čepa in ostane na grlu steklenice ali pa se, kot pri povratnih steklenicah, pretrga, vendar ostane pritrjen na lupino čepa.

Overview
EN 16592:2022 is the CEN standard that specifies the design and dimensional requirements for the 29 mm screw finish with three thread starts, designated PET finish 29/25 (12,6). The notation (12,6) denotes the vertical height in millimetres from the top of the finish to the bottom of the support ledge. This finish is intended for bottles used for flat water and non-carbonated beverages and is suitable for aseptic and nitrogen-assisted filling processes where internal overpressure does not exceed 1 bar.
Key benefits include consistent closure fit, reliable sealing performance for top/side/inside seals, and compatibility with tamper‑evident plastic closures (including attached caps).
Key Topics
- Design scope: 29 mm screw finish with three (3) thread starts spaced 120° apart.
- Critical dimensions: height X = 12,6 mm (top to bottom of support ledge); preform diameter under the support ledge indicated as Ø28,00 mm.
- Thread geometry:
- Lead: 6,5 mm (travel per turn)
- Thread run-in/run-out radii: 6,25 mm
- 180° of full thread per lead
- Tolerances and weight:
- General tolerance for other radii: ±0,13 mm
- Weight at height 12,6 mm: 2,42 g (using density = 1,335 g/cm³)
- Finish quality requirements:
- Smooth finish free of defects affecting sealing
- Flash not to exceed 0,13 mm per side and shall not be continuous
- Control diameter on blown bottle must be defect-free up to 4 mm down the internal bore and across the sealing surface
- Capping/closure requirements:
- Designed to accept only tamper‑evident plastic closures
- Allows attached caps
- Out-of-parallel sealing surface tolerance: 0,13 mm maximum
- Thread mismatch at mould seam: ≤ 0,10 mm
- No overhang between specified diameters; limited flush step allowed (0,15 mm on one side)
Applications
This finish is primarily used where consistent closure performance is critical:
- Bottled flat water and non-carbonated beverages
- Aseptic filling lines and nitrogen‑assisted filling (internal overpressure ≤ 1 bar)
- Bottle manufacturers, preform designers, closure suppliers and bottling line engineers seeking standardized neck geometry for trouble-free capping and tamper‑evident solutions
Practical considerations: maintain tight control of the preform diameter under the support ledge for reliable capping; ensure capping equipment is properly adjusted and maintained.
Related Standards
- EN 16592:2022 supersedes earlier edition EN 16592:2014 and aligns with CEN/TC 261 packaging guidance.
- Relevant guidance and datasheets referenced in the standard include Cetie data sheets (e.g., FS18.00, DT23.03) and Cetie Guide N°5 for closure application on PET bottles.
For implementation, consult the full EN 16592:2022 text and national standards bodies for official national adoption and any additional implementation notes.
