Overview
prEN 16287 (2011) - published by CEN as a draft European Standard - specifies the dimensional requirements for a 28 mm screw finish for glass containers designated MCA 1. The MCA 1 finish is intended for pressurised or vacuum liquids closed with tamper‑evident closures (metal or plastic). This draft standard is based on CE.T.I.E. data sheet GME 32‑05 and is intended to harmonize finish dimensions for compatibility between glass containers, closures and tooling across Europe.
Key topics and technical requirements
- Finish designation: MCA 1 finish for pressure capsules; 28 mm nominal screw finish.
- Threads and pitch: Pitch specified at 3.175 mm (equivalent to 8 TPI).
- Cutter and helix: Cutter diameter ≈ 12.5 mm; helix angle β given (approx. 2°12') with a formula to calculate tan β from pitch and nominal thread diameters.
- Bore and profile details: Minimum through‑bore of Ø 16.0 mm and detailed thread/profile geometry illustrated in figures.
- Sealing surface: The sealing surface must be smooth and free of defects or flash; several bore‑entrance constructions are shown to suit glass manufacturers.
- Tolerances and diameters: Guidance on mean diameter limits and tolerances (mean diameter within ±0.2 mm; average of max/min “L” diameter to be close to nominal).
- Manufacturing notes: Notes on mould parting line, optional depressed thread at mould parting, and transition details (Z‑Z last full depth; gradual increase to full thread diameter D1 over 90° turn).
- Reference data: Derived from CE.T.I.E. GME 32.05 (bibliography provided).
Applications and who should use it
- Glass container designers and manufacturers - to specify and produce MCA 1 28 mm finishes that fit standardized closures.
- Closure (cap) and tamper‑evident closure manufacturers - to design compatible caps for pressurised liquids.
- Tooling and mould makers - to machine accurate finish profiles and bore entrances.
- Filling and bottling operations - to ensure closure compatibility and sealing performance for pressurised products (e.g., carbonated beverages, certain liquid foods, or pressurised industrial fluids).
- Quality, inspection and regulatory teams - to verify finish dimensions and tolerances during incoming inspection or product certification.
Related standards
- CE.T.I.E. data sheet GME 32‑05 (source technical data).
