oSIST prEN 16290:2011: Glass Packaging - MCA 7.5 R Screw Finish for Pressure Capsules

Overview

oSIST prEN 16290:2011 is a European draft standard developed by CEN/TC 261 Packaging Committee. It specifies the precise dimensions and design requirements for an 18 millimetres screw finish on glass containers, specifically designated as the MCA 7.5 R finish. This finish is intended for bottles subject to internal pressure, such as those used for carbonated beverages or pressurized liquids.
The standard ensures compatibility with tamper-evident closures made of metal or plastic, and plays a critical role in safeguarding the integrity and performance of pressure capsule packaging.

Key Topics

• Scope and Purpose
  Defines the exact dimensional specifications for the MCA 7.5 R screw finish to assure effective sealing and safety in pressurized glass containers.

• Technical Definitions

  • MCA finish: A screw finish designed to accommodate closures that preserve pressurized or vacuum contents with tamper evidence.
  • Clarifications on thread pitch, helix angle, and diameter tolerances precise to industrial usage.

• Dimensional Requirements
  The document details:

  • Pitch and thread specifications (3.387 mm pitch, helix angle of 2° 22’)
  • Critical diameters with tolerances around ±0.2 mm for mean diameters
  • Smooth sealing surface requirements to avoid defects and ensure leak protection
  • Bore entrance design alternatives to suit different glass manufacturers

• Thread Profile and Construction Limits
  Illustrations and guidelines specify the thread shape, depth, and transitions ensuring functional engagement and pressure resistance.

Applications

This standard is vital for manufacturers and designers involved in:

• Glass container production, particularly bottles used in pressurized environments like beverage carbonation or pharmaceutical vacuum sealing.
• Manufacturers of pressure capsules and tamper-evident closures, ensuring proper fit and functionality with MCA 7.5 R finish bottles.
• Packaging engineers aiming to optimize product safety, reduce wastage from leakage or breakage, and maintain consistent global compatibility.
• Quality control specialists implementing uniform dimensions that comply with market regulations and consumer safety standards.

Related Standards

• CE.T.I.E. GME 32-06: The MCA 7.5 R finish is based on this International Technical Centre for Bottling data sheet, ensuring industry-wide alignment.
• Other CEN packaging standards addressing glass container specifications and closures, ensuring a harmonized approach across European markets.
