Wide-mouth glass containers; vacuum lug finishes; dimensions

This technical specification addresses the dimensional characteristics of glass containers designed with wide mouths and vacuum flange closures. The document establishes a unified set of measurements and tolerances specifically for the neck region of bottles utilized in packaging applications requiring a secure vacuum seal. It defines critical parameters such as outer diameters, thread specifications, and sealing surfaces to ensure compatibility across various manufacturing processes. By standardizing these geometric attributes, the specification facilitates interchangeability between containers and their corresponding closures produced by different manufacturers. The guidelines cover the fundamental geometry necessary for the assembly and performance of these vessels, ensuring consistent quality and fit. This approach supports global trade by removing technical barriers related to size discrepancies. The outlined dimensions are essential for the production, inspection, and quality control of glass packaging intended for beverages, pharmaceuticals, or other products requiring hermetic sealing. The focus remains strictly on the physical specifications required for the proper functioning of the vacuum flange mechanism in wide-mouthed glass bottles.
