More Information
Summary:A full aperture beverage end (14) has a centre panel (30), a countersink (22) surrounding the centre panel (30), a main score (50) arranged in proximity to the countersink (22) to define a removeable aperture panel (54) and a vent score (46). The beverage end (14) is adapted for use with products that are pressurised to over 200 kPa when opened and during opening the vent score (46) is adapted to sever first, controlling the pressure differential between the external surface and internal surface of the centre panel (30), thereby allowing the main score (50) to tear in a controlled and reliable manner. The centreline of the main score 50 is located between 0.000 and 0.508 mm (0.020 inches) from the centre (C) of the transition radius (R) between the countersink (22) and the centre panel (30).
