The present invention concerns a full aperture beverage end (14) having 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 30 psi (207 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.
A full aperture beverage end comprising:
A full aperture beverage end according to claim , wherein the main score has an outer wall proximate a lip and an inner wall proximate the aperture panel, the inner and outer walls are separated by a land and the score residual thickness (Ta) of the land adjacent to the outer wall is less than the score residual thickness (Tb) of the land adjacent to the inner wall, whereby upon detachment of the aperture panel from the center panel of the end, the land remains attached to the aperture panel.
A sealed container comprising a container body with a product contained therein and a full aperture beverage end connected thereto by a seam the beverage end including:
