EN 13029:2009 – Packaging – Light-gauge metal packaging – Apertures for plug-in plastic closures
1 Scope
This European Standard specifies the dimensions and profile of the aperture for Type A and Type B plug-in plastic closures used in round and non-round metal containers of nominal wall thickness equal to or less than 0,49 mm.
2 General requirements
If a burr is produced at the piercing diameter it shall be kept to a minimum to avoid leakage.
The thickness, hardness and shape of the sheet around the aperture shall be such that the top end is not deformed by the axial load when the closure is pressed in.
Figure 1 and Figure 2 show examples of Type A and Type B closures respectively.
NOTE The specifications for the metal substrate are laid down in EN 10202, packaging types are described in EN ISO 90-2 and the recommended dimensions may be found in EN 13025-1 and EN 13026.
